I knew I was about to get laid off so I stopped caring and started answering questions on stack overflow all day every day instead of working.
10k rep later I got a new job via stack overflow careers that pays twice as much.
Moral of the story? Be efficient... even when you are not.5 -
"You mean to tell me that you deleted the class that holds all our labels and spin boxes together?" I said exasperatedly.

"You're probably wondering how we got to this stage? Let's wind back a little, shall we?"

A light tapping was heard at the entrance of my office.
"Oh hey [Boss] how are you doing?" I said politely
"Do you want to talk here, or do you want to talk in my office? I don't have anyone in my office right now, so..."
"Ok, we can go to your office," I said.
We walked momentarily, my eyes following the newly placed carpeting.
Some words were shared, but nothing that seemed mildly important. Just necessary things to say. Platitudes, I supposed you could call them.
We get to his office, it was wider now because of some missing furniture. I quickly grab a seat.
"So tell me what you've been working on," I said politely.
"I just finished up on our [project] that required proper saving and restoring."
"Great! How did you pull it off?" I asked excitedly.
He starts to explain to me what he did, and even opens up the UI to display the changes working correctly.
"That's pretty cool," admiring his work.
"But what's going on here? It looks like you deleted my class." I said, looking at his code.
"Oh, yeah, that. It looked like spaghetti code so I deleted it. It seemed really bulky and unnecessary for what we were doing."
"Wait, hold on," I said wildly surprised that he thought that a class with some simple setters and getters was spaghetti code.
"You mean to tell me that you deleted the class that organizes all our labels and spin boxes together?" I said exasperatedly.
"Yeah! I put everything in a list of lists."
"What, that's not efficient at all!" I exclaimed
"Well, I mean look at what you were doing here," he said, as he displays to me my old code.
"What's confusing about that?" I asked politely, but a little unnerved that he did something like this.
"Well I mean look at this," he said, now showing his "improved" code.
"We don't have that huge block of code (referring to my class) anymore filling up the file." He said almost a little too joyously.
"Ok, hold on," I said to him, waving my hand. "Go back to my code and I can show you how it is working. Here we are getting all the labels and spin boxes into their own objects." I said pointing a little further down in the code. "Down here we are returning the spin boxes we want to work with. Here and here, are setters so we can set maximum and minimum values for the spin box."
"Oh... I guess that's not that complicated. but still, that doesn't seem like really good bookkeeping." He said.
"Well, there are some people that would argue with you on that," I said, thinking about devRant.
He quickly switches back to his code and shows me what he did. "Look, here." He said pointing to his list of lists. "We have our spin boxes and labels all called and accounted for. And further down we can use a for loop to parse through them."
He then drags both our version of the code and shows the differences. I pause him for a moment
"Hold on, you mean you think this" I'm now pointing at my setters "is more spaghetti than this" I'm now pointing at his list of lists.
"I mean yeah, it makes more sense to me to do it this way for the sake of bookkeeping because I don't understand your Object Oriented Programming stuff."
...
After some time of going back and forth on this, he finally said to me.
"It doesn't matter, this is my project."
Honestly, I was a little heart broken, because it may be his project but part of me is still in there. Part of my effort in making it the best it can be is in there.
I'm sorry, but it's just as much my project as it is yours.16 -
Someday my toaster is going to have an IP address. A bad automatic firmware update will most likely cause it to get stuck on the bagel setting until I plug a usb key in and reflash the memory.
Grandma's refrigerator will probably get viruses, lock itself and freeze all the food inside, demanding bitcoin before defrosting.
My blender will probably be used in a massive DDoS attack because Ninja's master MAC address list got leaked and the hidden control panel login is admin/admin.
Ovens will burn houses down when people call in to have them preheat on their way home from work.
Correlations between the number of times the lights are turned on and how many times the toilet is flushed will yield recommendations to run the dishwasher on Thursdays because it's simply more energy efficient.
My dog will tweet when he's hungry and my smart watch will recommend diet dog food in real-time because he's really been eating too much lately--"Do you want to setup a recurring order on Amazon fresh?"

Just sharing my experience of my spontaneous interview with Facebook. I'm not good at writing these but here you go :)
- I was working as an Android dev and didn't have much knowledge in algorithms nor competitive programming, never ever interviewed with big companies.
- a random day on LinkedIn, a recruiter from Facebook contacted me
- I ignored it for few week because I thought it's so out of my league, then somehow, out of blue, I had a thought of giving it a try, so I did
- passed first round
- start studying algorithms a little for phone interview in 3 weeks
- recklessly took the phone interview
- passed
- start studying intensively (while working fulltime) for the on-site interview in 2 months
- almost got the job, they gave me one more chance by a followed up interview
- messed up the last chance real bad
- failed!!!
- Initially I just wanted to give it a try, but the fact that I failed at very very last chance, frankly, bothers me a bit. Maybe I will interview with FB or big companies if I have chance later, but I know for sure that the studying had made me a much better dev. All the code I write now is much more efficient (I think), I can and not anymore afraid of reading complicated code.
- Overall, it does takes a lot of time (~4 months studying while working fulltime), but also benefits myself a lot though I didn't get the job, so basically, good experience, but better if I got the job 😁
Oops, wanted to write a few lines and it's a long post already.. I should stop here :D9 -
Lads, I will be real with you: some of you show absolute contempt to the actual academic study of the field.
In a previous rant from another ranter it was thrown up and about the question for finding a binary search implementation.
Asking a senior in the field of software engineering and computer science such question should be a simple answer, specifically depending on the type of job application in question. Specially if you are applying as a SENIOR.
I am tired of this strange self-learner mentality that those that have a degree or a deep grasp of these fundamental concepts are somewhat beneath you because you learned to push out a website using the New Boston tutorials on youtube. FOR every field THAT MATTERS a license or degree is hold in high regards.
"Oh I didn't go to school, shit is for suckers, but I learned how to chop people up and kinda fix it from some tutorials on youtube" <---- try that for a medical position.
"Nah it's cool, I can fix your breaks, learned how to do it by reading blogs on the internet" <--- maintenance shop
"Sure can write the controller processing code for that boing plane! Just got done with a low level tutorial on some websites! what can go wrong!"
(The same goes for military devices which in the past have actually killed mfkers in the U.S)
Just recently a series of people were sent to jail because of a bug in software. Industries NEED to make sure a mfker has aaaall of the bells and whistles needed for running and creating software.
During my masters degree, it fucking FASCINATED me how many mfkers were absolutely completely NEW to the concept of testing code, some of them with years in the field.
And I know what you are thinking "fuck you, I am fucking awesome" <--- I AM SURE YOU BLOODY WELL ARE but we live in a planet with billions of people and millions of them have fallen through the cracks into software related positions as well as complete degrees, the degree at LEAST has a SPECTACULAR barrier of entry during that intro to Algos and DS that a lot of bitches fail.
NOTE: NOT knowing the ABSTRACTIONS over the tools that we use WILL eventually bite you in the ASS because you do not fucking KNOW how these are implemented internally.
Why do you think compiler designers, kernel designers and embedded developers make the BANK they made? Because they don't know memory efficient ways of deploying a product with minimal overhead without proper data structures and algorithmic thinking? NOT EVERYTHING IS SHITTY WEB DEVELOPMENT
SO, if a mfker talks shit about a so called SENIOR for not knowing that the first mamase mamasa bloody simple as shit algorithm THROWN at you in the first 10 pages of an algo and ds book, then y'all should be offended at the mkfer saying that he is a SENIOR, because these SENIORS are the same mfkers that try to at one point in time teach other people.
These SENIORS are the same mfkers that left me a FUCKING HORRIBLE AND USELESS MESS OF SPAGHETTI CODE
Specially to most PHP developers (my main area) y'all would have been well motherfucking served in learning how not to forLoop the fuck out of tables consisting of over 50k interconnected records, WHAT THE FUCK
"LeaRniNG tHiS iS noT neeDed!!" yes IT fucking IS
being able to code a binary search (in that example) from scratch lets me know fucking EXACTLY how well your thought process is when facing a hard challenge, knowing the basemotherfucking case of a LinkedList will damn well make you understand WHAT is going on with your abstractions as to not fucking violate memory constraints, this-shit-is-important.
So, will your royal majesties at least for the sake of completeness look into a couple of very well made youtube or book tutorials concerning the topic?
You can code an entire website, fine as shit, you will get tested by my ass in terms of security and best practices, run these questions now, and it very motherfucking well be as efficient as I think it should be(I HIRE, NOT YOU, or your fucking blog posts concerning how much MY degree was not needed, oh and btw, MY degree is what made sure I was able to make SUCH decissions)
This will make a loooooooot of mfkers salty, don't worry, I will still accept you as an interview candidate, but if you think you are good enough without a degree, or better than me (has happened, told that to my face by a candidate) then get fucking ready to receive a question concerning: BASIC FUCKING COMPUTER SCIENCE TOPICS
* gays away into the night53 -
Not so much screaming as staring in disbelief, mumbling profanity in his direction...
When my department lead said "I don't think this unit testing hype or code reviews make much sense, it's more efficient to just make a checklist and test the application yourself"
This was the QA department of an aerospace company, we wrote NDT software to do image recognition on xrays of alloy welds and micrometer laser measurements on fuel tank surfaces. Software which is quite mission critical, a single misrecognized welding fault could literally cost up to half a billion dollars — not to mention that it's a very sabotage & espionage sensitive industry.
After raising some hell he was replaced though.3 -
5 Types Of Programmers
1.The duct tape programmer
The code may not be pretty, but damnit, it works!
This guy is the foundation of your company. When something goes wrong he will fix it fast and in a way that won’t break again. Of course he doesn’t care about how it looks, ease of use, or any of those other trivial concerns, but he will make it happen, without a bunch of talk or time-wasting nonsense. The best way to use this person is to point at a problem and walk away.
2.The OCD perfectionist programmer
You want to do what to my code?
This guy doesn’t care about your deadlines or budgets, those are insignificant when compared to the art form that is programming. When you do finally receive the finished product you will have no option but submit to the stunning glory and radiant beauty of perfectly formatted, no, perfectly beautiful code, that is so efficient that anything you would want to do to it would do nothing but defame a masterpiece. He is the only one qualified to work on his code.
3.The anti-programming programmer
I’m a programmer, damnit. I don’t write code.
His world has one simple truth; writing code is bad. If you have to write something then you’re doing it wrong. Someone else has already done the work so just use their code. He will tell you how much faster this development practice is, even though he takes as long or longer than the other programmers. But when you get the project it will only be 20 lines of actual code and will be very easy to read. It may not be very fast, efficient, or forward-compatible, but it will be done with the least effort required.
4.The half-assed programmer
What do you want? It works doesn’t it?
The guy who couldn’t care less about quality, that’s someone elses job. He accomplishes the tasks that he’s asked to do, quickly. You may not like his work, the other programmers hate it, but management and the clients love it. As much pain as he will cause you in the future, he is single-handedly keeping your deadlines so you can’t scoff at it (no matter how much you want to).
5.The theoretical programmer
Well, that’s a possibility, but in practice this might be a better alternative.
This guy is more interested the options than what should be done. He will spend 80% of his time staring blankly at his computer thinking up ways to accomplish a task, 15% of his time complaining about unreasonable deadlines, 4% of his time refining the options, and 1% of his time writing code. When you receive the final work it will always be accompanied by the phrase “if I had more time I could have done this the right way”.
What type of programmer are you?

I think the coolest project I did was a few years ago, it was actually a Minecraft plugin.
I decided to learn Java for Minecraft, and a few months after I started learning Java, I was approached by someone who'd like to work with me to create this full-blown Gun Game style gamemode for Minecraft. I made it clear I didn't have the most knowledge, but I was willing to learn.
We began working on the project, the projects main class was bigger than any project I had worked on. Within a few months, it became one of the more popular plugins out there, even though we were still in an alpha mode. Had nearly 1,000 servers running the plugin, over 10k+ players total testing out the plugin.
Cause of this project, I learnt how to properly organize my code, how to make it efficient, learnt how to network, learned how to properly secure and verify anything being sent by the client, working with dependencies, adding features that can support a bunch of other plugins that other developers had, and a bunch more.
Sadly we couldn't finish the plugin anymore, so we gave someone else the source code who has kept it updated to this day. (I know I didn't provide much insight into what I'm saying and just gave a general overview, got a killer headache.)2 -
1. I wish that people start taking back their device ownership. Right to repair is an extremely important thing. Like that Nexus 6P that I've recently repaired by jamming another battery into it, now it's at 110-ish% health according to AccuBattery. And it cost me.. €10 or so? All the while if I wasn't able to get in there, it would've been a €120 paperweight (and that's not even considering the €300-ish (? Someone please fill me in on that) price it retailed at back in 2015 when it was a flagship).
(edit the so many'th: according to https://express.co.uk/life-style/... the base model was apparently £449 at release, haven't been able to verify it though.. point is, a paperweight at such prices would've been quite a bummer, I mean for me it was even one given that it failed a mere few months after purchase for €120.. €40/m for a phone ain't nothing :/)
Right to repair is an extremely important thing, and the ability to do so shouldn't ever be impeded. Users should become able again to service the devices that they own.
2. I wish that people start caring about their privacy again. Google and Facebook and the likes are large companies, but at the end of the day, that's all they are. Large companies. And they're hungry for your data, not because they're selling it, rather because they're collecting it to an extent which they shouldn't. Over at DDG (https://spreadprivacy.com/duckduckg...) they explain a very much viable alternative revenue model pretty well. Additionally, there's several tools which you can use to limit the amount of data that's being collected about you. These include but are not limited to Firefox, NoScript, ad blockers (I personally use uBlock), a trustworthy VPN (ideally one of your own), and Tor.
3. I wish that software would become less inefficient. It really pains me to see that applications with functionality that could be implemented in a couple of MB at most come at a size of several hundreds of MB. 1% efficiency, even the inefficient as fuck tungsten light bulbs weren't that awful!!! Imagine what could be done with all the hardware we have available nowadays, if every piece of software would be around 80% efficient as is a common norm in electronics. Just looking at Linux which is still in many ways convoluted, modern desktops with a couple hundred MB of RAM usage? You've got it! So why can't OS's like Windows (although I have to say, huge improvements have been made there over the last few years) and browsers like Firefox and Chrome be more like that? I really don't understand.
There's several more wishes I have of course, but those are the most important ones.. hopefully I'll be able to see at least one of them come true during my life.10 -
TLDR;
Wrote a slick scheduling and communication system allowing me to assign photography resources based on time and location.
I'll tell you a little secret ... I'm not actually a dev. I'm a photographer, pretending to be a dev.
Or ... perhaps it's the other way around? (I spend most of my time writing code these days, but only for me - I write the software I use to run my business).
I own a photography studio - we specialize in youth volleyball photography (mostly 12-18 year old girls with a bit of high school, college and semi-pro thrown in for good measure - it's a hugely popular sport) and travel all over the US (and sometimes Europe) photographing.
As a point of scale, this year we photographed a tournament in Denver that featured 100 volleyball courts (in one room!), playing at the same time.
I'm based in California and fly a crew of part-time staff around to these events, but my father and I drive our booth equipment wherever it needs to go. We usually setup a 30'x90' booth with local servers, download/processing/cashier computers and 45 laptops for viewing/ordering photographs. Not to mention 16' drape and banners, tons of samples, 55' TVs, etc. It's quite the production.
We photograph by paid signup only - when there are upwards of 800 teams/9,600 athletes per weekend playing, and you only have four trained photographers, you've got to manage your resources!
This of course means you have to have a system for taking sign those sign ups, assigning teams to photographers and doing so in the most efficient manner possible based on who is available when the team is playing. (You can waste an awful lot of time walking from one court to another in a large convention center - especially if you have to navigate through large crowds - not to mention exhausting yourself).
So this year I finally added a feature I've wanted for quite some time - an interactive court map. I can take an image of the court layout from the tournament and create an HTML version in our software. As I mouse over requests in one window, the corresponding court is highlighted on the map in another browser window. Each photographer has a color associated with them. When I assign requests to a photographer, the court is color coded with the color of the photographer. This allows me to group assignments to minimize photographer walk time and keep them in a specific area. It's also very easy to look at the map and see unassigned requests and look to see what photographer is nearby.
This year I also integrated with Twilio and setup a simple set of text shortcuts that photographers can use to let our booth staff know where they are, if they have memory cards that need picking up, if they need water/coffee/snack, etc. They can also move assignments on their schedule or send and SOS for help if it looks like they aren't going to be able to photograph a team.
Kind of a CLI via the phone. :)
The additions have turned out to be really useful and has made scheduling and managing the photographers much easier that it was in the past.

Holy fucking shit! Coding by yourselves seem so much fucking more efficient than in a team. Fuck you team! I know you might say this makes me a bad programmer. But you know what fuck you too!8

This story starts over two years ago... I think I'm doomed to repeat myself till the end of time...
Feb 2014
[I'm thrust into the world of Microsoft Exchange and get to learn PowerShell]
Me: I've been looking at email growth and at this rate you're gonna run out of disk space by August 2014. You really must put in quotas and provide some form of single-instance archiving.
Management: When we upgrade to the next version we'll allocate more disk, just balance the databases so that they don't overload in the meantime.
[I write custom scripts to estimate mailbox size patterns and move mailboxes around to avoid uneven growth]
Nov 2014
Me: We really need to start migration to avoid storage issues. Will the new version have Quotas and have we sorted out our retention issues?
Management: We can't implement quotas, it's too political and the vendor we had is on the nose right now so we can't make a decision about archiving. You can start the migration now though, right?
Me: Of course.
May 2015
Me: At this rate, you're going to run out of space again by January 2016.
Management: That's alright, we should be on track to upgrade to the next version by November so that won't be an issue 'cos we'll just give it more disk then.
[As time passes, I improve the custom script I use to keep everything balanced]
Nov 2015
Me: We will run out of space around Christmas if nothing is done.
Management: How much space do you need?
Me: The question is not how much space... it's when do you want the existing storage to last?
Management: October 2016... we'll have the new build by July and start migration soon after.
Me: In that case, you need this many hundreds of TB
Storage: It's a stretch but yes, we can accommodate that.
[I don't trust their estimate so I tell them it will last till November with the added storage but it will actually last till February... I don't want to have this come up during Xmas again. Meanwhile my script is made even more self-sufficient and I'm proud of the balance I can achieve across databases.]
Oct 2016 (last week)
Me: I note there is no build and the migration is unlikely since it is already October. Please be advised that we will run out of space by February 2017.
Management: How much space do you need?
Me: Like last time, how long do you want it to last?
Management: We should have a build by July 2017... so, August 2017!
Me: OK, in that case we need hundreds more TB.
Storage: This is the last time. There's no more storage after August... you already take more than a PB.
Management: It's OK, the build will be here by July 2017 and we should have the political issues sorted.
Sigh... No doubt I'll be having this conversation again in July next year.
On the up-shot, I've decided to rewrite my script to make it even more efficient because I've learnt a lot since the script's inception over two years ago... it is soooo close to being fully automated and one of these days I will see the database growth graphs produce a single perfect line showing a balance in both size and growth. I live for that Nirvana.6 -
I've been working exclusively from home for over 2 years now. I've been seeing several posts from people talking about adjusting to working from home, so I figured I would compile a list of tips I've learned over the years to help make the adjustment easier for some people.
1) Limit as many distractions as possible. WFH makes it much easier to get distracted. If you have roommates/family members at home, ask them politely to leave you alone while you're working. Make sure the TV is turned off, put your phone on silent, etc.
2) Take regular breaks. I find it easier to accidentally go hours without taking a real break from work. Try working in half hour intervals, and then taking 5-10 minute breaks. Read an article, watch a youtube video, grab some coffee/tea, etc.
3) When you eat lunch, eat it away from your computer. I often find myself eating lunch trying to wrap up fixing a bug, which makes it feel like I never really "took a lunch." Lately I've been trying to step away and do something else completely unrelated to work.
4) Get ready for work like you normally would. It's very easy to wake up, throw on your favorite pair of sweats and sit at the computer with messy hair half awake "ready" to start the day. Instead try doing your normal morning routine before sitting at your computer. It will help your mind and body go into "it's time to work" mode.
5) Keep your work area clean. I find it very difficult to work when my workspace is cluttered. Studies have shown working in a messy place tend to make us less efficient.
6) Keep your work area work related. Try to only have the things you need for work in your workspace. If you're working from your personal computer this can be difficult. I always end up with camera/music equipment left over from the previous night's photo editing/jam sessions. So try to clean off your desk when you're done for the night so it's ready for work in the morning.
7) Prepare for meetings. I have alarms set 10 minutes in advance so I can go from programming mode to meeting mode. During this time I'll go to the bathroom, grab a snack, water, mute all my email notifications, close any non essential programs, get my code ready if I need to present it.
Stuff is hard & stressful right now, but hopefully these tips will make it a bit easier. If anyone else has any good tips please share them.5 -
Part 1: https://devrant.com/rants/4210605
So let's talk about these tasks we were assigned. Ms Reliable and Mr DDTW's friend who I just realized I haven't named yet were in charge of programming communications. Ms Enabler and Mr DDTW were in charge of creating the vehicle subclasses for the new variants we were instructed to build. Each one had to handle one variant, and we estimated that both of these would be about the same difficulty (Ms Enabler's one turned out to be a little harder).
I like Ms Enabler, and she's a good friend, although she isn't the best at problem solving and her strengths as a dev lie in her work ethic and the sheer amount of theory she knows and can apply. These just so happened to be the exact opposites of my strengths and weaknesses. Within a few days of having assigned the tasks, she came up to me asking for help, and I agreed. Over the following couple of weeks I'd put in quite a lot of hours reviewing the design with her, and we'd often end up pair programming. It was more work for me, but it was enjoyable and overall we were very efficient.
The other two girls in the group were also absolutely fine this sprint. They simply did the work they had to and let us know on time. Outside of some feedback, requests, bugfixes, and mediating disagreements, I didn't have to do anything with their tasks.
A week and half into the sprint and everybody else has their part almost in an MVP state. As Mr DDTW hadn't said or shown anything yet, I asked if he could push his stuff to the repo (he got stuck with this and needed help btw), and what does he have?
A piece of shit "go to this location" algorithm that did not work and was, once again, 150 lines of if statements. This would not have been such a massive deal if THE ENTIRE PREVIOUS SPRINT HAD BEEN DEDICATED TO MAKING THE CODE DO THIS IN A SENSIBLE WAY. Every single thing that this guy had written was already done. EVERY SINGLE THING. A single function call with the coordinates would let the vehicle do what he wrote but in a way THAT ACTUALLY WORKED AND MADE THE TINIEST BIT OF FUCKING SENSE. He had literally given so few shits about this entire goddamn project that he had absolutely zero clue about what we'd even done last sprint.
After letting this man civilly know through our group chat about his failures, giving him pointers on what's wrong and what he can use and telling him that he should fix it by the end of the week, his response?
"I'll try"
That was it. Fuckass was starting to block us now, and this was the first sign of activity he's given since the sprint started. Ms Enabler had finished her work a fucking week ago, and she actually ASKED when she ran into trouble or thought that something could be improved. Mr DDTW? He never asked for shit, any clarification, any help, and I had let everybody know that I'm open. At least the other two who didn't ask for shit ACTUALLY DID SOMETHING. He'd been an useless sack of shit for half a semester in three separate projects and the one time he's been assigned something half important that would impact our grades he does this. I would not stand for it.
I let him know all this, still civil (so no insults) but much less kind, capped with "Stop fooling around. Finish this by the of the week." which probably came off as a threat but his shithead kinda had it coming.
He was actually mad. Dropped a huge faux-apologetic spiel in the chat. Why couldn't I just trust him (his code was garbage and he was constantly late without explanation), his work was almost done (it wasn't and if he'd started he'd understand the scope of what he was assigned), that the problem was that I'm a condescending piece of shit (bruh), and was suddenly very interested in doing work. Literally everybody ignored him. What was funny was seeing the first questions and requests for help after that spiel. I obliged and actually answered what he asked.
The end of the week came and went he'd just uploaded more garbage that didn't work. I had foreseen this and, on top of everything else, had been preparing his section of the work done by myself and properly. Thus came a single commit from me with a working version of the entire module, unblocking the entire team. I cannot imagine the sheer hatred for this man at that moment for the commit message to simply be:
"judgement"
And with that, all I got was a threat to report me to the professor for sabotaging his work. The following day our group got an email from the professor, with no explanation, asking for an almost-immediate video conference. Group chat was a shitshow of panic, as nobody knew what was going on. Least of all Mr DDTW.
Once again, I'm approaching the word limit so to be continued in part 3 (hopefully of 3)7 -
Beware, this is gonna be a long one.
Today, in university, our professor wanted us to do an algorithm where a number was given in input, and we had to see if that number was, as she put it, "triangular".
For example:
3 is triangular because it's 1+2.
6 is triangular because it's 1+2+3.
10 is triangular because it's 1+2+3+4.
And so on.
While she was explaining this, I was programming it on my phone (because I didn't bring a PC there).
In about 10 minutes I completed it.
This student who was beside me, which I didn't know until today (I'm still in my first year here), saw me programming it, and when I finished it, he looked at it and said: "It takes too much time, like this."
So he spent another like 5-10 minutes """fixing""" it, and then showed it to me: "Here, now it's better."
Do you want to know what he did?
The only thing he did was putting a for cycle instead of my while cycle.
And he didn't even do it properly!
He put an else statement inside the brackets of an if, and some variables weren't correct.
You call that making a program more efficient? Deficient is more like it.
Also, like 5-10 minutes after I did it on my phone, on my own, I looked at the prof's desk: a guy (who apparently is "the best") wrote his algorithm on the blackboard, and the whole fucking class applauded.
Later, I saw on our Whatsapp group that someone sent a photo of him writing on the blackboard, with the caption "The student surpasses the teacher." Others agreed.
I replied with: "For the record, I did this algorithm in 10 minutes."
An asshole replied: "You'll never be superior to the master"
Fuck off. -.-"
...I'll show them.22 -
Finally, the jeezless present is done.. fuck this shit, where's my booze and my bed?! 😒
Anyway, it's essentially a power bank with LED's attached to it. The LED matrix is at the back side and looks reasonably decent (but I don't wanna disclose the age it's displaying). It's powered through a 47ohm resistor and is directly attached to the 5V lines. Yellow LED's with 2V voltage drop that have each number completely parallelized, and then those numbers are put in series to increase the combined forward voltage of the LED's to 4V. That way the circuit is around 80% efficient (resistor drops 1V, LED's drop the remaining 4V). Other than that, nothing too special. It did take 2 nights to build though.. way too much for a mere formality 😑

You can't keep wasting your time on people who do not know what the fuck they want. You could be way more time efficient with serious clients.
*After I have finally deployed the requested features*
Client: Why did it take you two weeks in the end? You said it would take you a couple days.
Me: Because you told me to use my imagination on half of the tasks and you kept wanting me to change what I had created, thus unnecessarily doubling the time it should have taken. Besides that probably the unclear communication and the fact that you rarely called me back after you told me to call you.
Client: So if I tell you, exactly, how I want it next time you'll be able to do it in a couple days?
Me: I'm not sure, that depends on what you want. Tell me, exactly, what you want.
Client: Oh it's not much, I'll let you do your thing for the most.
Me: I can't handle another request, sorry. *Ends call*4 -

Hi everybody! I am sorry that as a first time poster I am building 2 long stories, but I really like the idea of connecting with other people here!
Well, as I was mentioning before, I got a job in Android development and had a blast with it. Me and the developer clicked and would spend our time discussing PHP, the move to other stacks (I was making him love the idea of Django or Spring Java) games, bands and cool stuff like that. This dude was my hero, his own stack was developed in a similar MVC fashion that he had implemented from scratch before for many projects. It was through him that I learned how to use my own code (rather than frameworks and other libraries) to build what I wanted. I seriously thought that I had it made with a position that respected me and placed me in the lead mobile development position of the company. Then it happened. He had taken 2 weeks of unauthorized leave, which was ok since he was best friends with the owner of the company, those 2 along another asshole started it so they could do whatever they wanted. And I could not make much progress without him being there since there were things that he needed to do, that I was not allowed, for me to continue. When he came back I was quickly rushed to the owner of the company's office to discuss my lack of progress. The lead developer was livid, as if he knew that he had fucked up. He blamed the whole thing on me (literally told the owner that it was my fault before I was summoned) and that we lost 2 weeks of business time because I did not had the initiative to make progress on my own. I felt absolutely horrible, someone that I had trusted and befriended doing something like that, I really felt like shit. I had mad respect and love for this guy. It got heated, I showed the owner the text messages in which I showed him my pleas to led me finish the parts that were needed while he was away. Funny enough, he acted betrayed. After that it was 3 months of barely talking to one another except for work related stuff. He got cold and would barely let me touch the internal code that he was developing. It was painful. The owner kept complaining about progress and demanded that I do a document scanner for the company, which was to be attached to their mobile application. Not only that but it had to be done with OpenCV. Now, CV is great, but it is its own area, it takes a while to be able to develop something nice with it that is efficient and not a shitstorm.
I had two weeks.
Finished in one. After burning my brain and ensuring that the c++ code was not giving issues and the project was steady I turned it in...to their dismay. And I say so because I felt that they gave me such a huge project with the intention of firing me if it was not done. After that it was constant shit from the owner and the lead developer. I was asked then to port the code to the IOS version. I had some knowledge of it already so I started working on it. Progress was fast since the initial idea was already there and I really love working on Apple devices. And when I was 70% done the owner decided to cut me loose. At first he cited things such as lack of funding and him being unable to pay my salary. I was fine with that even though I knew it was not true. So at the time I just nodded and thanked the company for my time there. Before I left, he decided to blame it on me, stating that if they were not producing money that it was perhaps my fault. I lost my shit, and started using my military voice to explain to him how a software company is normally ran. Then I stormed out.
It was known to me, that the lead developer had actually argued against me being laid off. And that he was upset about it, we made amends, but the fact remains that I was laid off because the owner did not think of me as an asset, regardless of how many times I worked alongside the lead developer or how valuable I was actually to the company, their infrastructure did get better while we worked together, so I just assumed that he never actually did any mention of my value.
I lasted 2 months without a job, feeling horribly shitty because my wife had to work harder to ensure our stability whilst I was without any sort of salary. At this time I had already my degree, so all I had to do was look better. In the meantime I decided to study more about other technologies. I learn React, and got way better at JS and Node that I thought I could and was finally able to get another job as a full stack developer for another company.
I have been here since 2 months. It has been weird, we do classic ASP, which is completely pointless at this time, but meh. At this time though, I just don't really have the same motivation. Its really hard for me to trust the people that I work with and would like to connect with more developers.21 -
I miss the good times when the web was lightweight and efficient.
I miss the times when essential website content was immediately delivered as HTML through the first HTTP request.
I miss the times when I could open a twitter URL and have the tweet text appear on screen in two seconds rather than a useless splash screen followed by some loading spinners.
I miss the times when I could open a YouTube watch page and see the title and description on screen in two seconds rather than in ten.
I miss the times when YouTube comments were readily loaded rather than only starting to load when I scroll down.
JavaScript was lightweight and used for its intended purpose, to enhance the experience by loading content at the page bottom and by allowing interaction such as posting comments without having to reload the entire page, for example.
Now pretty much all popular websites are bloated with heavy JavaScript. Your browser needs to walk through millions of bytes of JavaScript code just to show a tweet worth 200 bytes of text.
The watch page of YouTube (known as "polymer", used since 2017) loads more than eight megabytes of JavaScript last time I checked. In 2012, it was one to two hundred kilobytes of HTML and at most a few hundred kilobytes of JavaScript, mostly for the HTML5 player.
And if one little error dares to occur on a JavaScript-based page, you get a blank page of nothingness.
Sure, computers are more powerful than they used to be. But that does not mean we should deliberately make our new software and website slower and more bloated.
"Wirth's law is an adage on computer performance which states that software is getting slower more rapidly than hardware is becoming faster."

How many of you uses Linux? I personally used for the first time Antergos (that discontinued, memed, arch based distros) with kde, then I started using Manjaro with gnome, as Manjaro was unsupported by most of the communities because it was arch based, I decided to move to Ubuntu, I sticked around on Ubuntu with gnome and then I installed i3, omg I loved i3 so much, after months of Ubuntu with i3 I decided to try new desktop environments/distros, so I installed xubuntu, xfce was boring, but efficient, just perfect! Then I installed kde neon, just to try it out! Now I still have kde neon and I'm thinking about trying Debian!
What about you?

Consumers ruined software development and we the developers have little to no chance of changing it.
Recently I read a great blog post by someone called Nikita, the blog post talks mostly about the lack of efficiency and waste of resources modern software has and even tho I agree with the sentiment I don't agree with some things.
First of all the way the author compares software engineering to mechanical, civil and aeroespacial engineering is flawed, why? Because they all directly impact the average consumer more than laggy chrome.
Do you know why car engines have reached such high efficiency numbers? Gas prices keep increasing, why is building a skyscraper better, cheaper and safer than before? Consumers want cheaper and safer buildings, why are airplanes so carefully engineered? Consumers want safer and cheaper flights.
Wanna know what the average software consumer wants? Shiny "beautiful" software that is either dirt ship or free and does what it needs to. The difference between our end product is that average consumers DON'T see the end product, they just experience the light, intuitive experience we are demanded to provide! It's not for nothing that the stereotype of "wizard" still exists, for the average folk magic and electricity makes their devices function and we are to blame, we did our jobs TOO well!
Don't get me wrong, I am about to become a software engineer and efficient, elegant, quality code is the second best eye candy next to a 21yo LA model. BUT dirt cheap software doesn't mean quality software, software developed in a hurry is not quality software and that's what douchebag bosses and consumers demand! They want it cheap, they want it shiny and they wanted it yesterday!
Just look at where the actual effort is going, devs focus on delivering half baked solutions on time just to "harden" the software later and I don't blame them, complete, quality, efficient solutions take time and effort and that costs money, money companies and users don't want to invest most of the time. Who gets to worry about efficiency and ms speed gains? Big ass companies where every second counts because it directly affects their bottom line.
People don't give a shit and it sucks but they forfeit the right to complain the moment they start screaming about the buttons not glaring when hovered upon rather than the 60sec bootup, actual efforts to make quality software are made on people's own time or time critical projects.
You put up a nice example with the python tweet snippet, you have a python script that runs everyday and takes 1.6 seconds, what if I told you I'll pay you 50 cents for you to translate it to Rust and it takes you 6 hours or better what if you do it for free?
The answer to that sort of questions is given every day when "enganeers" across the lake claim to make you an Uber app for 100 bucks in 5 days, people just don't care, we do and that's why developers often end up with the fancy stuff and creating startups from the ground up, they put in the effort and they are compensated for it.
I agree things will get better, things are getting better and we are working to make programs and systems more efficient (specially in the Open Source community or high end Tech companies) but unless consumers and university teachers change their mindset not much can be done about the regular folk.
For now my mother doesn't care if her Android phone takes too much time to turn on as long as it runs Candy Crush just fine. On my part I'll keep programming the best I can, optimizing the best I can for my own projects and others because that's just how I roll, but if I'm hungry I won't hesitate to give you the performance you pay for.

I previously worked as a Linux/unix sysadmin. There was one app team owning like 4 servers accessible in a very speciffic way.
* logon to main jumpbox
* ssh to elevated-privileges jumpbox
* logon to regional jumpbox using custom-made ssh alternative [call it fkup]
* try to fkup to the app server to confirm that fkup daemon is dead
* logon to server's mgmt node [aix frame]
* ssh to server directly to find confirm sshd is dead too
* access server's console
* place root pswd request in passwords vault, chase 2 mangers via phone for approvals [to login to the vault, find my request and aprove it]
* use root pw to login to server's console, bounce sshd and fkupd
* logout from the console
* fkup into the server to get shell.
That's not the worst part... Aix'es are stable enough to run for years w/o needing any maintenance, do all this complexity could be bearable.
However, the app team used to log a change request asking to copy a new pdf file into that server every week and drop it to app directory, chown it to app user. Why can't they do that themselves you ask? Bcuz they 'only need this pdf to get there, that's all, and we're not wasting our time to raise access requests and chase for approvals just for a pdf...'
oh, and all these steps must be repeated each time a sysadmin tties to implement the change request as all the movements and decisions must be logged and justified.
Each server access takes roughly half an hour. 4 servers -> 2hrs.
So yeah.. Surely getting your accesses sorted out once is so much more time consuming and less efficient than logging a change request for sysadmins every week and wasting 2 frickin hours of my time to just copy a simple pdf for you.. Not to mention that threr's only a small team of sysadmins maintaining tens of thousands of servers and every minute we have we spend working. Lunch time takes 10-15 minutes or so.. Almost no time for coffee or restroom. And these guys are saying sparing a few hours to get their own accesses is 'a waste of their time'...
That was the time I discovered skrillex.4 -
I really enjoy my old Kindle Touch rather than reading long pdf's on a tablet or desktop. The Kindle is much easier on my eyes plus some of my pdf's are critical documents needed to recover business processes and systems. During a power outage a tablet might only last a couple of days even with backup power supplies, whereas my Kindle is good for at least 2 weeks of strong use.
Ok, to get a pdf on a Kindle is simple - just email the document to your Kindle email address listed in your Amazon –Settings – Digital Content – Devices - Email. It will be <<something>>@kindle.com.
But there is a major usability problem reading pdf's on a Kindle. The font size is super tiny and you do not have font control as you do with a .MOBI (Kindle) file. You can enlarge the document but the formatting will be off the small Kindle screen. Many people just advise to not read pdf's on a Kindle. devRanters never give up and fortunately there are some really cool solutions to make pdf's verrrrry readable and enjoyable on a Kindle
There are a few cloud pdf- to-.MOBI conversion solutions but I had no intention of using a third party site my security sensitive business content. Also, in my testing of sample pdf's the formatting of the .MOBI file was good but certainly not great.
So here are a couple option I discovered that I find useful:
Solution 1) Very easy. Simply email the pdf file to your Kindle and put 'convert' in the subject line. Amazon will convert the pdf to .MOBI and queue it up to synch the next time you are on wireless. The final e-book .MOBI version of the pdf is readable and has all of the .MOBI options available to you including the ability for you to resize fonts and maintain document flow to properly fit the Kindle screen. Unfortunately, for my requirements it did not measure-up to Solution 2 below which I found much more powerful.
Solution 2) Very Powerful. This solution takes under a minute to convert a pdf to .MOBI and the small effort provides incredible benefits to fine tune the final .MOBI book. You can even brand it with your company information and add custom search tags. In addition, it can be used for many additional input and output files including ePub which is used by many other e-reader devices including The Nook.
The free product I use is Calibre. Lots of options and fine control over documents. I download it from calibre-ebook.com. Nice UI. Very easy to import various types of documents and output to many other types of formats such as .MOBI, ePub, DocX, RTF, Zip and many more. It is a very powerful program. I played with various Calibre options and emailed the formatted .MOBI files to my Kindle. The new files automatically synched to the Kindle when I was wireless in seconds. Calibre did a great job!!
The formatting was 99.5% perfect for the great majority of pdf’s I converted and now happily read on my Kindle. Calibre even has a built-in heuristic option you can try that enables it to figure out how to improve the formatting of the raw pdf. By default it is not enabled. A few of the wider tables in my business continuity plans I have to scroll on the limited Kindle screen but I was able to minimize that by sizing the fonts and controlling the source document parameters.
Now any pdf or other types of documents can be enjoyed on a light, cheap, super power efficient e-reader. Let me know if this info helped you in any way.

i honestly hate the ap computer science principles curriculum. we're taking an ap test soon, so for the past few weeks, we've been constantly taking practice tests.
it pisses me off so much. the questions, the criteria, it's all bs.
we have questions like "what will reduce the digital divide?" with choices like "education for low income families on computers." like, I DONT FUCKING KNOW.
frankly, I DONT FUCKING CARE. giving electronics to people who cant afford it is great and all, BUT IT DOESNT INVOLVE ANYTHING ABOUT COMPUTING.
HEY, COLLEGE BOARD, KNOWING IF AN ALGORITHM IS TECHNICALLY AN "ABSTRACTION" DOESNT FUCKING MATTER. WHAT MATTERS IS THAT I CAN IDENTIFY WHATS MORE EFFICIENT, WHERE A BUG IS, CONCEPTS INVOLVED IN PROGRAMS, THINGS LIKE THAT.
NOT IF DNS IS SIMILAR IN STRUCTURE TO THE US POSTAL SYSTEM.
god i hope whoever wrote this gets hit in the head by a github server that was dropped from the 2^8th floor.2 -
My CTO strongly discourages working from home because he insists that "leaning over to the next cube to ask a question" is far better than sending a message, email or making a phone call. He went as far as saying it takes too much effort to do the latter... How is interesting someone while they're working more efficient???10

My new favourite commit message:
"All changes as of 18th Sept"
How tremendously useful? There I was looking to know what changes were made to enable a feature / service, thought I could look for that in the commit message, but no you've given me a much more efficient way of finding out.
I simply need to download the contents of your memory, find out what date you made a change, and then dig through the massive commit to find the piece of info I need.
Forget experience using Git features, managing merges, following Git flow, or even any other SCM ... how can people be so tick when it comes to recording what they've done.
Heres a little cheat sheet for those struggling:
- Commit message
Describe what you actually ****ing did. Don't tell me the date or the time, thankfully Git records those. Don't tell me the day of the week, if I need to know I can figure that out, just tell me what ... you ... did.
- Feature branch names
Now this is a tricky one. You might be surprised to know that this isn't in fact suppose to be whatever random adjective or noun popped into your head ... I know, I too was shocked. The purpose of this is to let other people know what new feature is being worked on in this branch.
- Reusing feature branches
Now I know you started it to add some unit tests, and naming it "testing" is sort of ok. But its actually not ok to name it testing when you add 3 unit tests ... then rip out and replace 60% of the business logic. Perhaps it would have been wiser to create a new feature branch, given you are now working on a new feature.2 -
I think I've been doing too much Android programming in the last three days.
Had a lucid dream last night where I couldn't wake up until I figured out how to set up an inter-thread latch that would allow me to process through a shit ton of data points in parallel without duplication or skipping errors in the most efficient manner (effectively no blocking). We're talking several hundred lines of code. Slept 14 hours last night, I heard my alarm but didn't wake up. When I finally got up, I did what I did in my dream and it worked better than the existing code.
Turns out my brain is great at Java evaluation now, I guess.4 -
Is your code green?
I've been thinking a lot about this for the past year. There was recently an article on this on slashdot.
I like optimising things to a reasonable degree and avoid bloat. What are some signs of code that isn't green?
* Use of technology that says its fast without real expert review and measurement. Lots of tech out their claims to be fast but actually isn't or is doing so by saturation resources while being inefficient.
* It uses caching. Many might find that counter intuitive. In technology it is surprisingly common to see people scale or cache rather than directly fixing the thing that's watt expensive which is compounded when the cache has weak coverage.
* It uses scaling. Originally scaling was a last resort. The reason is simple, it introduces excessive complexity. Today it's common to see people scale things rather than make them efficient. You end up needing ten instances when a bit of skill could bring you down to one which could scale as well but likely wont need to.
* It uses a non-trivial framework. Frameworks are rarely fast. Most will fall in the range of ten to a thousand times slower in terms of CPU usage. Memory bloat may also force the need for more instances. Frameworks written on already slow high level languages may be especially bad.
* Lacks optimisations for obvious bottlenecks.
* It runs slowly.
* It lacks even basic resource usage measurement.
Unfortunately smells are not enough on their own but are a start. Real measurement and expert review is always the only way to get an idea of if your code is reasonably green.
I find it not uncommon to see things require tens to hundreds to thousands of resources than needed if not more.
In terms of cycles that can be the difference between needing a single core and a thousand cores.
This is common in the industry but it's not because people didn't write everything in assembly. It's usually leaning toward the extreme opposite.
Optimisations are often easy and don't require writing code in binary. In fact the resulting code is often simpler. Excess complexity and inefficient code tend to go hand in hand. Sometimes a code cleaning service is all you need to enhance your green.
I once rewrote a data parsing library that had to parse a hundred MB and was a performance hotspot into C from an interpreted language. I measured it and the results were good. It had been optimised as much as possible in the interpreted version but way still 50 times faster minimum in C.
I recently stumbled upon someone's attempt to do the same and I was able to optimise the interpreted version in five minutes to be twice as fast as the C++ version.
I see opportunity to optimise everywhere in software. A billion KG CO2 could be saved easy if a few green code shops popped up. It's also often a net win. Faster software, lower costs, lower management burden... I'm thinking of starting a consultancy.
The problem is after witnessing the likes of Greta Thunberg then if that's what the next generation has in store then as far as I'm concerned the world can fucking burn and her generation along with it.6 -
I recently tried to apply the same data analytics rationale that I use at work to my personal life. This is not a rant, it is more like an data storytelling of an actual use case I would like some input on.
I set a goal - gotta thin up a bit and calm down my ticker - and got a (almost unreasonably expensive) field expert consultant to yell at me about it for a couple hours.
I unravel the metrics - there is like a million weight-related KPIs and most say nothing at all. I have never seen an non-infrastructure measurable subject that could not be resumed to 2-5 performance metrics. I got overall weight, how well my nine-years-old business suit fits me, heart rate, and day-after relative muscle pain (it will make sense soon).
Then its data-pipeline time. I bought a cheap weight scale and smartwatch, and every morning I input the data in an app. Yes, I try to put on the suit every morning. It still does not fit.
After establishing a baseline, I tried to fit different approaches. Doing equipment-free exercises, going to the gym, dieting. None was actually feasible in the long run, but trying different approaches does highlight the impacts and the handling profile of each method.
Looking at the now-gathered data, one thing was obvious - can't do dieting because it is not doable to have a shopping list and meals for me and another for the family.
Gym is also off the table - too much overhead. I spend more time on the trip there and back than actually there.
And home exercise equipment is either super crappy or very expensive. But it is also the most reasonable approach.
So it is solutions time. I got a nice exercise bycicle (not a peloton), an yoga mat (the wife already had that one) and an exercise program that uses only those two resources. Not as efficient without dieting, not as measurable and broad as the gym, but it fits my workflow. Deploy to production!
A few months pass and the dataset grows. The signal is subtle but has support - it works! The handling, however, needs improvement, since I cannot often enough get with the exercise program. Some mornings are just after some hard days.
I start thinking about what else I can improve in the program, but it is already pretty lean and full of compromises.
So I pull an engineer and start thinking about the support systems and draft profile. What else could be draining my willpower and morning time?
Chores. Getting the kids ready for school, firing up the moka pot, setting the off-brand roomba, folding the overnight-dried clothes, cooking breakfast, doing the dishes, cleaning the toilets. All part of my morning routine. It might benefit from some automation.
Last month I got that machine our elders call "wasteful" and "useless crap lazy entitled Americans invented because they feel oh-so-insulted for simply doing something by hand like everyone always did" - a "dish-washer".
Heh, I remember how hard was to convince my mother-in-law that an remote-controled electric garage door would not make she look like an spoiled brat.
Still to early to call, but I think that the dishwasher just saved me about 25 mins every morning. It might be enough to save willpower for me to do more exercise.
This is all so reflective of all data analytics cases really are out in the wild - the analytics phase seems so small compared to the gathering and practical problem-solving all around. And yet d.a. is what tells you that you are doing the wrong thing all along. Or on what you should work next.7 -
Back when I was still in school for comp sci we had an advanced software engineering and design class with c++. At this time, everyone was expected to be proficient enough with cpp to go ahead and properly work with whatever the instructor would throw at us. And pretty much everyone was since past classes included a lot of c++ development. Of course, efficient at least related to academic studies rather than actual real world development.
Our teacher would mix in a lot pf phyisics and mathematics into what we were doing, something that I greatly enjoyed, while at the same time putting real world value concerning cpp best practices to avoid common pitfalls in the development of said language. Since most bugs seemed to be memory based he would be particularly strict about that.
One classmate, good friend and an actual proper developer now a days would ALWAYS forget to free his resources...ALWAYS for whatever fucking reason he would just ignore that shit, regardless of how much the instructor would make a point on it.
At one point during class on a virtual lecture the dude literally addressed a couple of students but when he got to my boy in particular he said: "you are the reason why people are praying to Mozilla and Hoare to release Rust as fast as possible into a suitable alternative to high performant code in C++, WHY won't you pay attention to how you deal with memory management?"
And it stuck with me. I merely a recreational cpp dev, most of my profesional work is done on web development, so I cannot attest to all the additional unsafe code that people encounter in the wild when dealing with cpp on a professional level.
But in terms of them common criticisms of C and C++ for which memory is so important to work with, wouldn't you guys say that it comes more from the side of people just not knowing what they are doing rather than a fault on the language itself?
I see the merits and beauty of Rust, I truly do, it is a fantastic language, with a standardized build system and a lot of good design put into it. But I can't really fathom it being the cpp killer, if anything, the real cpp killers are bad devs that just don't know what they are doing or miss shit.
What do y'all ninjas think?8 -
In 2015 I sent an email to Google labs describing how pareidolia could be implemented algorithmically.
The basis is that a noise function put through a discriminator, could be used to train a generative function.
And now we have transformers.
I also told them if they looked back at the research they would very likely discover that dendrites were analog hubs, not just individual switches. Thats turned out to be true to.
I wrote to them in an email as far back as 2009 that attention was an under-researched topic. In 2017 someone finally got around to writing "attention is all you need."
I wrote that there were very likely basic correlates in the human brain for things like numbers, and simple concepts like color, shape, and basic relationships, that the brain used to bootstrap learning. We found out years later based on research, that this is the case.
I wrote almost a decade ago that personality systems were a means that genes could use to value-seek for efficient behaviors in unknowable environments, a form of adaption. We later found out that is probably true as well.
I came up with the "winning lottery ticket" hypothesis back in 2011, for why certain subgraphs of networks seemed to naturally learn faster than others. I didn't call it that though, it was just a question that arose because of all the "architecture thrashing" I saw in the research, why there were apparent large or marginal gains in slightly different architectures, when we had an explosion of different approaches. It seemed to me the most important difference between countless architectures, was initialization.
This thinking flowed naturally from some ideas about network sparsity (namely that it made no sense that networks should be fully connected, and we could probably train networks by intentionally dropping connections).
All the way back in 2007 I thought this was comparable to masking inputs in training, or a bottleneck architecture, though I didn't think to put an encoder and decoder back to back.
Nevertheless it goes to show, if you follow research real closely, how much low hanging fruit is actually out there to be discovered and worked on.
And to this day, google never fucking once got back to me.
I wonder if anyone ever actually read those emails...
Wait till they figure out "attention is all you need" isn't actually all you need.
p.s. something I read recently got me thinking. Decoders can also be viewed as resolving a manifold closer to an ideal form for some joint distribution. Think of it like your data as points on a balloon (the output of the bottleneck), and decoding as the process of expanding the balloon. In absolute terms, as the balloon expands, your points grow apart, but as long as the datapoints are not uniformly distributed, then *some* points will grow closer together *relatively* even as the surface expands and pushes points apart in the absolute.
In other words, for some symmetry, the encoder and bottleneck introduces an isotropy, and this step also happens to tease out anisotropy, information that was missed or produced by the encoder, which is distortions introduced by the architecture/approach, features of the data that got passed on through the bottleneck, or essentially hidden features.4 -
I just reallized I've done so much photo editing that I made a few tools for it in different apps.
So this morning in a flash of insight, I've made a single app that consolidates them all...
Basically it's just a window that opens all the others by referencing those projects... That was probably the fastest I've ever written an app... other than Hello World.
I can't tell if i am lazy, efficient, or organized... (i couldnt put this in the tag because of the commas)

Fellow Deviants, I need your help in understanding the importance of C++
Okay, I need to clarify a few things:
I am not a beginner or a newbie who has just entered this community...
I have been using C++ for some time and in fact, it was the language which introduced me to the world of programming... Before, I switched to Java, since I found it much better for application development...
I already know about the obvious arguments given in favour of C/C++ like how it is a much more faster and memory efficient than other languages...
But, at the same time, C/C++ exposes us and doesn't protect us from ourselves.. I hope that you understand what I mean to say..
And, I guess that it is a fair tradeoff for the kind of power and control that these languages (C/C++) provide us..
And, I also agree with the fact that it is an language that ideally suits our need, if we wish to deal with compilers, graphics, OS, etc, in the future...
But, what I really want to ask here is:
In this age and times, when hardware has advanced so much, where technically, memory efficiency or execution speeds no longer is the topmost priority... These were the reasons for which C/C++ was initially created...
In today's time, human concept of time matters more and hence, syntactical less complicated languages like Java or Python are much more preferred, especially for domains like application development or data sciences...
So, is continuing with C++, an endeavour worth sticking with in the future or is it not required...
I am talking about this issue since I am in a dilemma about the use of C++ in the future...
I would be grateful if we could talk about keeping AI, Machine Learning or Algorithms Optimisation in mind... Since, these are the fields in which I am interested in...
I know that my question could have been posted in a better way.. But, considering the chaos that is present in my mind, regarding this question doesn't allow me to do so...
Any kind of suggestion or thoughts would be welcome and much appreciated...
P.S: I currently use C++ only for competitive programming or challenges...28 -
If you've ever tried using Go plugins raise your hand.
If you've ever tried doing plugins in Go, raise your hand.
If you think that the following rant will be interesting, raise your hand.
If you raised your hand, press [Read More]:
This is a tale of pain and sorrow, the sorrow of discovering that what could be a wonderful feature is woefully incomplete, and won't be for a very long time...
Go plugins are a cool feature: dynamically load pre-compiled code, and interact with it in a useful and relatively performant way (e.g. for dynamically extending the capabilities of your program). So far it sounds great, I know right?
Now let me list off some issues (in order of me remembering them):
1. You can't unload them (due to some bs about dlopen), so you need to restart the application...
2. They bundle the stdlib like a regular Go binary, despite the fact that they're meant to be dynamic!
3. #2 wouldn't be so bad if they didn't also require identical versions of all dependencies in both binaries (meaning you'd need to vendor the dependencies, and also hope you are using the right Go version).
4. You need to use -trimpath or everything dies...
All in all, they are broken and no one is rushing to fix it (literally, the Go team said they aren't really supporting it currently...).
So what other options are there for making plugins in Go?
There's the Hashicorp method of using RPC, where you have two separate applications one the plugin, one the plugin server, and they communicate over RPC. I don't like it. Why? Because it feels like a hack, it's not really efficient and it carries a fear of a limitation that I don't like...
Then we come to a somewhat more clever approach: using Lua (or any other scripting language), it's well known, it's what everyone uses (at least in games...). But, it simply is too hard to use, all the Go Lua VMs I could find were simply too hard to set up...
Now we come to the most creative option I've seen yet: WASM. Now you ask "WASM!? But that's a web thing, how are you gonna make that work?" Indeed, my son, it is a web thing, but that doesn't mean I can't use it! Someone made a WASM VM for Go, and the pros are that you can use any WASM supporting language (i.e. any/all of them). Problem inefficient, PITA to use, and also suffers from the same issues that were preventing me from using Lua.
Enter Yaegi, a Go interpreter created by the same guys who made (and named) Traefik. Yes, you heard me right, an INTERPRETER (i.e. like python) so while it's not super performant (and possibly suffering from large inefficiency issues), it's very easy to set up, and it means that my plugins can still be written in Go (yay)! However, don't think this method doesn't have its own issues, there's still the problem of effectively abstracting different types of plugins without requiring too much boilerplate (a hard problem that I'm actively working on, commits coming soon). However, this still feels to be the best option.
As you can see, doing plugins in Go is a very hard problem. In the coming weeks (hopefully), I'm going to (attempt to at least) benchmark all the different options, as well as publish a library that should help make using Yaegi based plugins easier. All of this stuff will go (see what I did there 😉) in a nice blog post that better explains the issues and solutions. But until then I have some coding to do...
Have a good night(/day)!14 -

That guy at the office who gets really irritated and worried about newly introduced technology. He would spend 2-3 days talking trash about it, saying how much he prefers the older and less efficient approach just because he knows it.

Oh u know, I haven't done much of anything workwise since we all got sent home due to Corona. I feel bad about it but also like it's only partially my fault. I work like shit from home, true, but I would probably be more efficient if I had any way of knowing what I'm doing 😭 I switched depts a week before Corona and as a result I only got one hour of training in a new system and have had to teach myself the rest 😔 pour one out for ur homegirl who feels bad but also can't learn any quicker. I have half a mind to just respond to one of those pesky recruiters spamming me lately.2

So happy about being about to convince management that we needed a large refactor, due to requirements change, and since the code architecture from the beginning had boundaries built before knowing all the requirements...
pulled the shame on us, this is a learning lesson card.. blah blah blah
Also explained we need to implement an RTOS, and make the system event driven... which then a stupid programmer said you mean interrupt driven ... and management lost their minds... ( bad memories of poorly executed interrupts in the past).... had to bring everyone back down to earth.. explained yes it’s interrupt driven, but interrupt driven properly unlike in the past (prior to me)... the fuck didn’t properly prioritize the interrupts and did WAYYY too much in the interrupts.
Explained we will be implementing interrupts along side DMA, and literally no message could be lost in normal execution.. and explained polling the old way along side no RTOS, Wastes power, CPU resources and throws timing off.
Same fucker spoke up and said how the fuck You supposed to do timing, all the timing will be further off... I said wrong, in this system .. unlike yours, this is discreet timing potential and accurate as fuck... unlike your round robin while loop of death.
Anyway they gave me 3 weeks.. and the system out performs, and is more power efficient than the older model.
The interrupting developer, now gives me way more respect...4 -

-THE TRICK IS THAT NONE OF YOUR FAVORITE ADDONS WILL WORK!!!
Seriously this is fucking insane! Several of my addons which were essential for me to stay sane is gone and I don't even know how to live without them. And all this bullshit is happening because these idiots in Mozilla decided to enforce use of WebExtensions. For ones who unaware, WebExtensions is much, much poorer framework and many cool addons simply unable to work under WebExtensions because of its limitations.
Are you the one who loved the speed and joy of using mouse gestures? GUESS WHAT — IT'S GONE.
Maybe you made your browsing activity super efficient with use of the “Tab Groups” addon that used to allow you to group your browser sessions? SAY BYE-BYE TO IT!
And many more!
Most importantly, I cannot understand why would a company enforce use of a framework that will decrease functionality of a product.
Anyway, it seems like Firefox is not a browser for addon enthusiasts like me anymore; got to find a new one, any recommendations?11 -

So I'm on my morning stroll. Walking, enjoying, watching the world around me.. It's nice how cherries blossom. They smell very tempting to stop there and enjoy the moment. Some flowers under the cherry...
Why do plants blossom again? Oh yeah, that's right, to exchange some speciments in order to grow fruit and seeds. To have their offspring. Just like every other living macroorganism [with a few exceptions ofc]. Life has no other way to survive but to exchange genetic material between two parties and only then trigger growth of the new life.
And that is a very strict rule. No more, no less: it takes exactly 2 organisms to make new life. But why is that? If my memory serves, theory of evolution says that life is like business: cut the losses and let the profits run. Over time it discards everything not required for the organism in order to save energy, and only successful new "investments" remain in the genome. The unsuccessful ones die before they proliferate, so the bad genes shall not survive.
It also says that very simple things, very simple changes lead to very complex outcomes. Us. Life.
But what is simple about life having to need 2 other lives? Exactly 2. It's either simple or efficient, depends on perspective. BUT IT IS NOT BOTH. Look at cells. They just split in half and multiply. Dead simple. It takes one of them to make another one. But with mammals, birds, reptiles, plants and other macroorganisms [excpt fungi] this is not the case! Why?!? I can't think of any scenario where two generic microorganisms, following some dead simple mutations, would come up w/ something that inefficient and overly complex. Like they're living on their own, multiplying by division, and smth very simple happens and they can no longer divide, only mate in pairs. The primitive, efficient and simple mechanism gets terminated and replaced with a different one, incredibly complex one!
Sure, we have protozoa which have similar reproductive mechanisms. They exchange genetic material to multiply.
But look at our, human cells. They dont need that! Look at some reptiles, some plants that only take one to make another. They don't pair as well! It's simple. Efficient. Why do protozoa need 2 for the species to survive?
It's not simple and efficient [tho helps us adapt, but its not my point for now]. See, things like this make ne wonder. What if we, the life, are not as accidental as we think? What if this whole mechanism was set off by someone or something billions of years ago? That's mean there are much older, much more superior cognitive organisms than us. What if protozoa was version 3 of new life [the first two did not survive]? Viruses - v2? Sea creatures - v3, reptiles - v4, and so on until they came up with us, mammals? That'd surely mean we are not alone in this universe. Are they watching us? Will they create a new species any time soon? What's our purpose, are we just an experiment?
And so, from cherry blossoms to existensial dilemma, my stroll is over. Time for breakfast :)1 -
My implementation of facebook's haystack storage solution. It's certainly not a faithful recreation, but I think this served my needs better.
The idea is you store all of your files in one large file, and just write down where each of your files starts and ends. This particular implementation I called an indexed haystack because it gives you back an index, sort of like an array.
I was attracted to the idea because it makes the file structure of the server so much more simple, and backups so much easier when you only have a few files rather than a few thousand. Facebook came up with it because it was more efficient to store a million photos all in the same file rather than in a million separate ones.
There is a 100GB limit to each haystack but that isn't technical, it's just a sensible thing to do.

Spend 2 hours migrating my old NASs ubuntu zfs pool to the new freeBSD NAS, which has new fancy stuff like a crossflashed raid card new hyper efficient psu and so on. Sadly, the pool just wont import, many drives are missing. I debug. For hours. Trying to test cables. Interesting. No matter which SATA cables i switch, this one drive always starts... Hm... Must be the controller then. Maybe the controller doesnt spin up the other disks, because i removed the boot rom! That must be it! Wait... Why is this cable lying in here... Wait, this is the power cable attached to all missing driv ARE YOU FUCKING KIDDING ME?! I WASTED SO MUCH FUCKING TIME ON THIS SHIT HOW COULD YOU DO THIS TO ME!
Unfortunately, one power cable become loose (i dont know how, these cables have plastic thingies to prevent this...), but it works now. And its better than before. -
Working with a group on a startup idea. We have weekly Google chat meetings with the full team and sometimes me and the other two founders have side calls. Our group is getting bigger so the weekly is getting longer so the 3 of us were talking about ways to make them more efficient. One was, background distractions like TV, random people talking in bg, kids...
So then yesterday the 3 of us went over a different topic and the guy who had brought up the distraction issue was in the bathroom shaving and trimming nose hairs the whole time. He kept asking questions about the agenda which we all had access to. I shouldn't even care much. I drink through the meetings anyways.2 -
lord knows I have missed devrant. my dad dragged me away on business. the hardest part was parting with my PC. I felt it.........
we buy cashew nuts and have them exported for this random Chinese lady. tried discussing about computers to the village boys but none of them understand anything. everyone is surprised I have a whole computer to myself at home, most have never seen any and just nod their heads like they understand 😂😂😂.
my dad wants me to be a produce exporter I keep hearing things like "there's a lot of money here, if you want to start on your own I'll support you". but then it's hard for him to drop a penny so I can buy a proper PC that is used(I just needed something efficient). I kinda feel like this struggle will make my success story much more interesting but then, what if I dont succeed?4 -
Fuck I feel fucked up just for completing user account management, authentication, email verification, password reset. Securing all of this with ssl and checking for any security loopholes.
I can't believe this took me more than a couple months.
Well I was lazy and unmotivated.
I fucking hate crafting stupid ass routes in nginx.
I fucking hate making a nice responsive gui.
I have to design even the stupid html for the emails. Fuuuuck.
So much boilerplate on top of that with username and email validation.
I learnt regex 5 times over the past couple months, still not enough.
And now I actually have to build the functional part.
On the plus side I can reuse this stupid boilerplate if I can make it more modular and readable.
There's shit ton of comments to the point where I feel like an idiot for including so much info. It's like I've written it for a toddler to take over.
Gawd. Anyways it's over now. 50% I guess.
I can finish the rest of the server more quickly and then spend another year designing the Android application.
I'm really lazy in places where I have to design UI/UX. Although at this point it's kinda what could put my application at the top. (I'm lazy, I ain't bad.. I just hate implementing my ideas I wish I could just visualize and have it appear on my screen)
I do like parts of gui that involve little math problems that would make motion smooth and efficient. -
I freaking hate slow IDEs, especially ones made in Java.
I used to use an IDE/text editor called geany, and it was great, you could do almost every language in it and it worked great. It was fast, and efficient, it was a no-nonsense editor. That was when I was a kid, but I got in univ and got a job, so I had to start using big boy """""enterprise""""" IDEs like eclipse.
Eclipse, netbeans, and intellij (basically every Java based IDE except BlueJ) are exactly what is wrong with IDEs. They are clunky editors that frankly would be better off gone. They are slow, eat RAM like crazy (like most Java software). You just CANNOT have eclipse open for extended periods of time, because it WILL take up too much resources and get slow as heck. Android Studio (based on intellij) is a nightmare to work with. It just does not want to cooperate with you (I will agree they have improved a lot though).
I cannot believe I am saying this, but even the electron based IDEs like atom and code-oss are better than them. They are very easily expandable, something that Java was supposed to be, but is not. They have tons of plugins. Even if its not there, you can make one without having to spend a lifetime making the plugin! They look good. I never thought that going from IDEs with """""enterprise""""" UIs to something modern like code-oss would feel this great. Its ridiculous, I don't want to create a darn project for every single file that I want to edit, I just want syntax highlighting for a single .sh file that I want to edit right now. A project is just a way to logically define what is one "unit" or a "container for multiple files", you know what else is that? A simple directory.
Also I don't want 9 billion .xml files for the IDE to store its crap. Just make a .vscode like folder to hide your shit.11 -
A few months back, I was having the last few days of my college / university. Already had a job offer, wasn't fond of attending classes, so I had not much to do. I had been a student placement coordinator, and a few of other student coordinators along with the University Placement Cell decided to overhaul the current placement structure with a new, more efficient one. So, they asked whether I could take interviews (along with a few others) for new placement coordinators, who'd take over the following year, making the existing posts null and void.
So, I was interviewing a 2nd year girl for the technical team. In her form, she had mentioned that she'd been an executive member of the programming club of our University, founded the previous year, was peaking in terms of popularity among other clubs.
I found it strange, and during the interview, I kept pushing it until she accepted that she was just a member and not an executive member.
Then, I asked, do you know Bugs Buggy (name changed)... She said, yes, he is the founder of that club. I said, I am, Bugs Buggy.

So I promised a post after work last night, discussing the new factorization technique.
As before, I use a method called decon() that takes any number, like 697 for example, and first breaks it down into the respective digits and magnitudes.
697 becomes -> 600, 90, and 7.
It then factors *those* to give a decomposition matrix that looks something like the following when printed out:
offset: 3, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('2')]]
offset: 2, exp: [[Decimal('2'), Decimal('1')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('1')]]
offset: 1, exp: [[Decimal('7'), Decimal('1')]]
Each entry is a pair of numbers representing a prime base and an exponent.
Now the idea was that, in theory, at each magnitude of a product, we could actually search through the *range* of the product of these exponents.
So for offset three (600) here, we're looking at
2^3 * 3 ^ 1 * 5 ^ 2.
But actually we're searching
2^3 * 3 ^ 1 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
2^3 * 3 ^ 1 * 5 ^ 0
2^3 * 3 ^ 0 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
etc..
On the basis that whatever it generates may be the digits of another magnitude in one of our target product's factors.
And the first optimization or filter we can apply is to notice that assuming our factors pq=n,
and where p <= q, it will always be more efficient to search for the digits of p (because its under n^0.5 or the square root), than the larger factor q.
So by implication we can filter out any product of this exponent search that is greater than the square root of n.
Writing this code was a bit of a headache because I had to deal with potentially very large lists of bases and exponents, so I couldn't just use loops within loops.
Instead I resorted to writing a three state state machine that 'counted down' across these exponents, and it just works.
And now, in practice this doesn't immediately give us anything useful. And I had hoped this would at least give us *upperbounds* to start our search from, for any particular digit of a product's factors at a given magnitude. So the 12 digit (or pick a magnitude out of a hat) of an example product might give us an upperbound on the 2's exponent for that same digit in our lowest factor q of n.
It didn't work out that way. Sometimes there would be 'inversions', where the exponent of a factor on a magnitude of n, would be *lower* than the exponent of that factor on the same digit of q.
But when I started tearing into examples and generating test data I started to see certain patterns emerge, and immediately I found a way to not just pin down these inversions, but get *tight* bounds on the 2's exponents in the corresponding digit for our product's factor itself. It was like the complications I initially saw actually became a means to *tighten* the bounds.
For example, for one particular semiprime n=pq, this was some of the data:
n - offset: 6, exp: [[Decimal('2'), Decimal('5')], [Decimal('5'), Decimal('5')]]
q - offset: 6, exp: [[Decimal('2'), Decimal('6')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('5')]]
It's almost like the base 3 exponent in [n:7] gives away the presence of 3^1 in [q:6], even
though theres no subsequent presence of 3^n in [n:6] itself.
And I found this rule held each time I tested it.
Other rules, not so much, and other rules still would fail in the presence of yet other rules, almost like a giant switchboard.
I immediately realized the implications: rules had precedence, acted predictable when in isolated instances, and changed in specific instances in combination with other rules.
This was ripe for a decision tree generated through random search.
Another product n=pq, with mroe data
q(4)
offset: 4, exp: [[Decimal('2'), Decimal('4')], [Decimal('5'), Decimal('3')]]
n(4)
offset: 4, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('3')]]
Suggesting that a nontrivial base 3 exponent (**2 rather than **1) suggests the exponent on the 2 in the relevant
digit of [n], is one less than the same base 2 digital exponent at the same digit on [q]
And so it was clear from the get go that this approach held promise.
From there I discovered a bunch more rules and made some observations.
The bulk of the patterns, regardless of how large the product grows, should be present in the smaller bases (some bound of primes, say the first dozen), because the bulk of exponents for the factorization of any magnitude of a number, overwhelming lean heavily in the lower prime bases.
It was if the entire vulnerability was hiding in plain sight for four+ years, and we'd been approaching factorization all wrong from the beginning, by trying to factor a number, and all its digits at all its magnitudes, all at once, when like addition or multiplication, factorization could be done piecemeal if we knew the patterns to look for.7 -
AI is this huge scam to me. People keep saying it will take over everything and replace everything: jobs, people, etc. It is so over hyped by people who don't understand how it actually works.
I will wonder if AI can take over everything when they can build an AI that can weed a garden.
- no chemicals, too much is used and poisons everything.
- the garden cannot be specifically designed to be weed by machine.
- the AI must differentiate between weeds and non-weeds.
- the robotic system employed must not destroy everything else while weeding.
- the AI should know when it finds random objects like gloves, or shorts, cigarettes, or electrical components that they need attention or actually pick them up. Yes, I have found these.
- it should be quick and energy efficient and not require an entire nuclear plant to run the AI. What is the point of AI powered by a server somewhere if it pollutes from afar rather than local.
I just don't see this happening in my lifetime.18 -
This is why we can never have enough software developers
It's true. No matter how many people learn to program, there will never be enough people who know how to program. They don't have to be very good at it either. It is now a required skill.
Minimum wage in first world countries is way above 5$ per hour. A Raspberry PI 3B costs 40$, or at most 1 day of work for the worst paid jobs. And it will run for years, and do routine tasks up to thousands of times faster than any employee. With that, the only excuse that people still do routine tasks, is the inaccessibility of coder time.
Solution: everybody should know how to write code, even at the simplest level.
Blue-collar jobs: they will be obsolete. Many of them already are. The rest are waiting for their turn.
Marketing people - marketing is online. They need to know how to set up proper tracking in JS, how to get atomic data in some form of SQL, how to script some automated adjustments via APIs for ad budgets, etc. Right now they're asking for developers to do that. If they learn to do that, they'll be an independent, valued asset. Employers WILL ask for this as a bonus.
Project Managers - to manage developers, they need to know what they do. They need to know code, they have to know their way around repositories.
QA staff - scripted tests are the best, most efficient tests.
Finance - dropping Excel in favor of R with Markdown, Jupyter Notebooks or whatever, is much more efficient. Customizing / integrating their ERP with external systems is also something they could do if they knew how to code.
Operations / Category Management - most of it would go obsolete with more companies adopting APIs as a way to exchange important information, rather than phone calls and e-mails.
Who would not be replaced or who wouldn't benefit from programming? Innovative artists.
A lot of it might not be now now, but the current generation will see it already in their career.
If we educate people today, without advanced computer skills and some coding, then we are educating future deadbeats.
With all this, all education should include CS. And not just as a mandatory field or something. Make it more accessible, more interesting, more superficial if needed. Go straight to use cases, show its effectiveness in the easiest way possible. Inquisitive minds will fill in the blanks, and everyone else will at least know how to automate a part of their work. -
Thinking really hard about starting my own retro pc collection starting with the NEC pc-98 ......hmmmmmm wondee how my wife would feel about me spending money in this shit
Recently I have taken to all things retro tech, always liked it really, specially since my mom showed me pics of me playing with an old commodore 64 when i was younger as well as another of a family friend showing me the sharp 68k this shit fuels my appetite for knowing more about the programming ways of the old school coders. Some pretty interesting stuff, I feel that the newer generations would benefit greatly by knowing the things we had to do in order to build efficient programs back in the day. Not to say that I was part of that at all. I was born in 1991, how I came to see these systems is unknown and forgotten by me, but something that none the less os part of my story in computing.
Because of the industry that surrounds me I have been dealing with working with web development, but shit is really not that much of a passion of mine, had I the skills more than the academic knowledge I would love to work with low level C code all day, I just feel that the things that developers do there are so much more interesting than handilg web development, web development is tedious and a current shitstorm, not to say that shit was not like that for the programmers that i am referencing, but i just want more.
Web development has made me a successful man, at 28 i am the head of my department, I might sound like a Disney princess but I want more, I want more knowledge and more experience in different areas of Computer Science. I want to know it all and it seems like time continuously goes against me.
Oh well, here is to a new year lads, see what i can do.3 -
I think I would be much more efficient if I didn't have to sit on a chair and look at the screen while coding. Often it is so hindering to type with my fingers and I just wish I could code directly with my brain. 😶
Should I take a break? 😂

tl;dr i am proud of my universal program but annoyed it won't get appreciation.
<brag type='slightly'>the last three days i refactored my various snippets to a kind of modular and scalable software package. restricted to a rigid company system i make use of the technologies i feel confident in. so i created a javascript app that can be used with internet explorer. it is a neat tool to work smarter and mainly to make repetitive writing tasks efficient using predefined textblocks that have automated linguistic adjustments and are multilingual usable. after refactoring it is possible to extend any desired functionality by just adding another module. i learned a lot about implementing separated data structures, data processing, output and asynchronous script loading (and the annoying limitations of ie11).</brag>
i kept in mind that this tool might not only help my personal duties to be done more efficient but also might come in handy to all my colleagues having similar tasks to do. the downside is my colleagues having irrational computerphobia and i know for sure they will proceed to do these repetitive writings manually resulting in inconsistencies and an inefficient time management. while my wise wife tries to convice me that at least i had fun coding this stuff and having it supporting me with annoying tasks, it still bothers me being the only user, as it means no progression for the company. it riddles me how the colleagues, acknowledging us all being craftspeople in the first place, avoid use of computers whenever possible and rather rely on medieval working flows.
i find it quite amusing to be the 'can you fix my printer'-guy, but i just cannot handle this attitude. and everyone complains about having so much to do. get your shit together and start clicking these few buttons goddammit! -
Reading. And not just a couple of genres, I mean as much as possible on as many topics as you can deem interesting. Classical literature, epics, poetry, contemporary criticism, post-modernism, every pretentious piece of work you can get your hands on.
Because the greater your vocabulary and the wider your understanding, the more efficient and proficient you become in learning new things.
Also, it makes you a better writer when you finally find yourself needing to put together some technical documentation for that content management system you whipped together in a fortnight.5 -

This story happened to everyone, and i am sure that if i search, i will find dozens of similar stories, but the different here is, i tried, i really tried, in a hundred different ways to achieve my goal !
When you are stuck on a problem, let's say, that you have a program, project, website ... and need to achieve something technically weird (or hard) and need some help to save you time on experimentations. The first thing a lot of people do is : Google.com && put search dorks.
But, at a moment, google gets "dirty", you use it so often that he always think to know better then you what you are looking for.
It reminds of "Ted", the movie (for thows who know it) where they asked : "Hey ! Why does google always suggest us to look for black dicks ??"
It is exactly what happened to me, i got results who doesn't have anything to do with what i was looking for !
You can give it a try now : type "semantic web RDF to RDB"
You won't find anything, except results related to : NOSQL DBs, which is totally annoying.
Something else, i once google swift to get some updates, what results did i got ? Taylor Swift ... (musician)
I often get 2 or 3 results from google, which made me thinking that i somewhat reached the end of internet, or that people are so dumb that i will have spend hours trying to figure my solutions, but, before doing that, other solutions had to be tested.
1- TOR : Google tracks his users and uses its algos and bullshits to return results as close as possible to the user's demand (big fail ...) so how about moving to a different country ? DL TOR browser, open, setup, go to US, open google (got us version YAY !) enter my keywords, and, nothing, still nothing, more results for sure, but nothing related to what i was looking for.
2- VM
Pop a VM, launch TOR, use Hidden mode, delet all cookies and stuff (it is a new VM but who knows).
Use keywords (now in UK). Here they are !! my results !!! i finally found some decent results about my keywords !
But, i have the required knowledge to do this kind of stuff, but how about people who rely heavily on google ? they can't change country, clear everything, trick google to think you are a new user, they have almost biased and flawed results. I tried duckduckgo (i love them) but they are not that efficient.
Google says not to anything evil, but they ARE EVIL, miss guiding people, suggesting corrections who have nothing to do with the keywords, or results totally unrelated in any way to the keywords while results exist in other countries ???
Ever since, i don't pay attention to google at all, and started thinking that google's algos are manipulating people, i don't know if it is done on purpose or not, but the result is the same, people have biased results based on their country, on their tag, on their ID, and the recent keywords.
During that period i was cursing google every funcking day, and i am still doing it, too much trackers, too much manipulation, i will end-up enclosing myself in darknet.4 -
I would enjoy a position where I would have to write tons of tiny scripts for solving different logic problems. Tweak data, visualise it, pass it through different mediums. I would feel the best in research, implementing and testing different ideas, and build solutions for later use. Right now I'm on the first line at the customer site where the upcoming problems have to be solved instantly, I have the constant feeling that the thing could be much more efficient but there is no time for change, test and implement differently, so I'm not really using my full capacity on anything. I'm kind of a user of the built stuff but I feel more a developer. At the other end I'm satisfied and this is the best job I ever had :)1

Programmer looking for a new language
I have been a JavaScript developer for a few years now (non professionally) and I really like the language. I mainly program for execution with NodeJS rather than web, because I feel like I get more freedom (e.i. the ability to use a computer file system).
I normally never use other people's libraries and instead either write my own library/ies for the specific task or use an old one. I only ever use someone else’s if I need a quick frame work to test an idea, never for something I will actually use.
I prefer to work object / class orientated.
I have worked on distributed servers with NodeJS before, however trying to distribute a load across one computer across it's multiple threads has proved problematic due to the heavy delays of standard io transfer speeds.
Why do I want to switch?:
•Because JavaScript is not at all created with multithreading in mind, and pretty much any multithreading solution is a bodge and allot of the time it is more efficient to work single threaded.
•Also, I get the sense that JavaScript + NodeJS is not used often in the programming industry comparison to other languages like; ruby, python, and I don't want to get stuck in a nesh language of which would decrease my employment chances heavy.
Side Note: I have been working on a pet project to have a distributed database (made with nodejs), and so far, there are no language specific problems, but I feel like it would be more efficient if I used a programming language designed more to cater for multi threading.5 -
I am really psyched about the tech to create voices for generated speech. I am really excited when in the future this tech might be small enough to deliver with a game or OS. Then much more interactive games can be built with generated text. It would be so cool to license voices for this kind of work.
It will probably end up with artists creating unique and interesting voices to allow game developers to pick and choose. So voice artists will be a thing as well as graphics artists. The tricky part will finding a way to add mood states to the generated voices. Right now this could be done with different voice profiles for different speech.
Right now the tech is "large", but this will rapidly become smaller and efficient as it gets developed more.1 -
<assumption>If there are no fundamental laws constraining the existence of simulated consciousness</assumption>, I would throw in my lot in working towards developing an AGI.
Since there is infinite time to learn any skill and <assumption>it is possible to learn or invent whatever software or mathematical framework is required for such a goal</assumption>, I would get down to that, learning and creating various new forms of mathematical frameworks and required software tools.
<assumption>Engineers usually work best without another fellow human on the project</assumption>, so I will set up automation for tasks that do benefit from multiple minds on a project, in the form of low-level artificial intelligence that I have to work on as a prerequisite for the main goal.
Once the critical mass is hit where the code can keep self-improving and produce more iterations of itself that are better, I sit back and start with my long, long to-watch/to-read list and try to finish as much as I can before the AGI I created would <assumption>repurpose all of our mortal flesh for more efficient use.</assumption>
The only remnant of the existence of humanity will be the influence on the initial design of the code based sentience that exists now.

Nothing much to ready today, keep scrolling..
I just asked you to keep scrolling, I am using this space to think out loud...
Damn you bloody rebel.. whatever..
Finally after a rough week, festivals, interviews, work stress, and pending tasks, I got a free weekend for myself to be with myself.
I managed to do bare minimum at work. My new line manager isn't quite pleased with how team and I am functioning but whatever.
On Fridays, I usually end the day early and start with personal tasks. I managed to finish some long pending activities.
Today, I was able to do a deep cleaning of digital housekeeping. Sorted some clashes with parents. manage to de-stress and relax my stiff neck muscles.
Apart from that I guess, I am all prepared to interview and get hired for a company on foreign land. I am confident that I can relocate to EU.
And for now, I am actively pursuing two of my hobbies, Music and Finances. I love managing my finances and learning more about technical aspects of audio and listening to more and more music.
I feel happier, relaxed, and calm. Having things under control is such a wonderful feeling.
And I am slowly building a framework to earn, manage, invest, and grow my finances. It's turning out really well. I have setup the base infrastructure.
For music, I have figured the fundamentals and now I will go out buy myself an DAC/AMP to build a portable rig.
This shit is so awesome and makes me happy. I am able to socialise at the end of each day so that keeps me going during the lock-down phase.
I have figured the top key and important things to do at work for my profile and I actually enjoy those.
1. Product discovery - talking to users/customers and finding their pain areas and opportunities to build the solution
2. Product vision/strategy - Dreaming on how the product would evolve and laying out a solid plan to materialise those dreams.
3. Roadmap and prioritisation - this should be self explanatory
4. Success metrics - I really want to get into data and I am getting opportunities to do so. This is super fun. This will help me analyse and show the impact of the what we are building and measuring it while making sure that LT recognises my and my teams' efforts.
I want to and I will excel these 4 keys skills of my profile and be more efficient at my job.
This will give me more time to pursue my hobbies (which will change over time and want to enjoy them the most while I am at them).
Guys, after a rough 2021, the end of the year seems promising with a lot of leaves and short vacation coming up.
Apart from all this, what is more important here is that I got the career and life clarity that I was struggling with for past few months.
For whoever has read till here, YOU ARE BLOODY AWESOME and thank you from the bottom of my heart for being there for me always.
I am grateful to be a part of this community and have awesome friends like you all who have been with me though my ups and downs since 2016.
LOVE YOU ALL :)3 -
TL;DR When talking about caching, is it even worth considering try and br as memory efficient as possible?
Context:
I recently chatted with a developer who wanted to improve a frameworks memory usage. It's a framework creating discord bots, providing hooks to events such as message creation. He compared it too 2 other frameworks, where is ranked last with 240mb memory usage for a bot with around 10.5k users iirc. The best framework memory wise used around 120mb, all running on the same amount of users.
So he set out to reduce the memory consumption of that framework. He alone reduced the memory usage by quite some bit. Then he wanted to try out ttl for the cache or rather cache with expirations times, adding no overhead, besides checking every interval of there are so few records that should be deleted. (Somebody in the chat called that sort of cache a meme. Would be happy , if you coukd also explain why that is so😅).
Afterwards the memory usage droped down to 100mb after a Around 3-5 minutes.
The maintainer of the package won't merge his changes, because sone of them really introduce some stuff that might be troublesome later on, such as modifying the default argument for processes, something along these lines. Haven't looked at these changes.
So I'm asking myself whether it's worth saving that much memory. Because at the end of the day, it's cache. Imo cache can be as big as it wants to be, but should stay within borders and of course return memory of needed. Otherwise there should be no problem.
But maybe I just need other people point of view to consider. The other devs reasoning was simple because "it shouldn't consume that much memory", which doesn't really help, so I'm seeking you guys out😁 -
I graduated from my High School last Spring, and since then as a part of a huge overhaul of the education systems, they decided to put the school into the 21st century. The problem? They're doing it all wrong. Every school in the district is acting on its own, making transitions from one grade to another painful. The middle school purchased a cart of iPads despite the fact that Elementary schools use Surface, and the High School uses 2-in-1s. But what makes it worse is the services. The High School used Office365 and OneNote, while the Middle School uses Google Classroom and cloud storage. If the school board wants to make education simpler, modern life, and efficient, the least you could do is have everyone on the same page. Right now, costs are higher, grades are confusing, and efficiency is lower. Each teacher pretty much fends for themselves. I volunteered to help them sort this out by being on the educational committee in charge of the decisions, but I graduated and they felt like they were doing fine. Seriously?1

Serious question here: why the discourse about spaces vs tabs? Hitting the tab key /once/ is just much more efficient than hitting the space bar /four times/, isn't it?9

What we will miss, if he really softens:
In fact, if the reason is stated as "it makes debugging easier", then I fart in your general
direction and call your mother a hamster.
In short: just say NO TO DRUGS, and maybe you won't end up like the Hurd people.
Of course, I'd also suggest that whoever was the genius who thought it was a good idea to read things ONE F*CKING BYTE AT A TIME with system calls for each byte should be retroactively aborted. Who the f*ck does idiotic things like that? How did they not die as babies, considering
that they were likely too stupid to find a tit to suck on?
Gnome seems to be developed by interface nazis, where consistently the excuse for not doing something is not "it's too complicated to do", but "it would confuse users".
I think the stupidity of your post just snuffed out everything
I think the OpenBSD crowd is a bunch of masturbating monkeys, in that they make such a big deal about concentrating on security to the
point where they pretty much admit that nothing else matters to them.
That is either genius, or a seriously diseased mind. - I can't quite tell which.
Christ, people. Learn C, instead of just stringing random characters together until it compiles (with warnings).
"and anybody who thinks that the above is
(a) legible
(b) efficient (even with the magical compiler support)
(c) particularly safe
is just incompetent and out to lunch.
The above code is sh*t, and it generates shit code. It looks bad, and
there's no reason for it." -
I get so tired of people hating on PHP, Javascript and promoting Python or C#/Java.
Python is basically Perl with slightly different syntax plus has py2/py3 issues. And suffers from pip like js does from npm.
Java/C# started as application languages, while PHP started in web servers (again from Perl but at least it now has full object support). So comparing apples and oranges is one thing.
Another one is that people don't seem to know much about PHP / js (and tbh not even about the languages they are promoting) when they try to hate. That just comes off as lazy and borderline idiotic. Don't be that guy.
If you have had a bad experience, maybe you need to open the documentation instead of copying code from stack overflow.
Again, lazy and unprofessional.
Devs are supposed to be able to find the most efficient solution, that takes as little code as possible, not as little time from them when they arent familiar with the subject.
Damn Im angry right now, this rant really worked me up! :D6 -
For those of us OCD Sheldon Cooper types out there, programming can get very annoying.
For example, I want to do everything as efficient as possible but sometimes situations require "live with it" or "quick and dirty" solutions, which grinds my teeth because I'm not applying perfection in everything and a laid back attitude is against my personality, much like Sheldon. It's the same annoyance as when Penny knocks twice but not thrice at the door.
This sure is easier for brogrammers.4 -
Building on yesterday's rant (https://devrant.com/rants/3110183/), after sleeping on it I realized that using groups was completely non-necessary, so I got rid of them and got a much more efficient (and faster) function:
Also, I've got these in a repo: https://github.com/chabad360/...

rant.author != this
Christ people. This is just sh*t.
The conflict I get is due to stupid new gcc header file crap. But what
makes me upset is that the crap is for completely bogus reasons.
This is the old code in net/ipv6/ip6_output.c:
mtu -= hlen + sizeof(struct frag_hdr);
and this is the new "improved" code that uses fancy stuff that wants
magical built-in compiler support and has silly wrapper functions for
when it doesn't exist:
if (overflow_usub(mtu, hlen + sizeof(struct frag_hdr), &mtu) ||
mtu <= 7)
goto fail_toobig;
and anybody who thinks that the above is
(a) legible
(b) efficient (even with the magical compiler support)
(c) particularly safe
is just incompetent and out to lunch.
The above code is sh*t, and it generates shit code. It looks bad, and
there's no reason for it.
The code could *easily* have been done with just a single and
understandable conditional, and the compiler would actually have
generated better code, and the code would look better and more
understandable. Why is this not
if (mtu < hlen + sizeof(struct frag_hdr) + 8)
goto fail_toobig;
mtu -= hlen + sizeof(struct frag_hdr);
which is the same number of lines, doesn't use crazy helper functions
that nobody knows what they do, and is much more obvious what it
actually does.
I guarantee that the second more obvious version is easier to read and
understand. Does anybody really want to dispute this?
Really. Give me *one* reason why it was written in that idiotic way
with two different conditionals, and a shiny new nonstandard function
that wants particular compiler support to generate even half-way sane
code, and even then generates worse code? A shiny function that we
have never ever needed anywhere else, and that is just
compiler-masturbation.
And yes, you still could have overflow issues if the whole "hlen +
xyz" expression overflows, but quite frankly, the "overflow_usub()"
code had that too. So if you worry about that, then you damn well
didn't do the right thing to begin with.
So I really see no reason for this kind of complete idiotic crap.
Tell me why. Because I'm not pulling this kind of completely insane
stuff that generates conflicts at rc7 time, and that seems to have
absolutely no reason for being anm idiotic unreadable mess.
The code seems *designed* to use that new "overflow_usub()" code. It
seems to be an excuse to use that function.
And it's a f*cking bad excuse for that braindamage.
I'm sorry, but we don't add idiotic new interfaces like this for
idiotic new code like that.
Yes, yes, if this had stayed inside the network layer I would never
have noticed. But since I *did* notice, I really don't want to pull
this. In fact, I want to make it clear to *everybody* that code like
this is completely unacceptable. Anybody who thinks that code like
this is "safe" and "secure" because it uses fancy overflow detection
functions is so far out to lunch that it's not even funny. All this
kind of crap does is to make the code a unreadable mess with code that
no sane person will ever really understand what it actually does.
Get rid of it. And I don't *ever* want to see that shit again. -
Hi So I need some solid advice from you all wonderful people.
I think i am now ready to look into job side of this world, but have lots of doubts , read my story.
I have been learning android for last 2 years. Most of the time i have been trying to understand how stuff works in android , but i have also gained a few other skills ( python programming, kotlin/flutter basics data analysis basics, testing, some graphic designing, aweful web dev ,etc). But i really want to work with Android. I don't have any specific Salary figure in mind, but i guess my knowledge is better or atleast par with most of the good android developers.
So i want to know how is this fresher/placement thingy work?
1.) GETTING KNOWN? : How can i make some good android based company aware that I am available for hiring? Should i start emailing every android related company that i know of? Should i start listing my profile on recruitment sites like linkedin or internshala? This year it is being said that companies will come for placements. From the status of my college, they are going to give me way to less $ , nd i know am not going to like any of them, but i guess i have to sit for them too.
2.INTERVIEW OR DIRECT PLACEMENTS? A little pre-context: i am currently starting my 4th year in clg. Afaik , 4th year isnt that strict and their can be leniency in terms of attendance. But my college is a place full of political cun*s in the name of directors and HODs and I don't know if they are again going to enforce the old 75% mandatory criteria. Plus if the company is from a different state/country , then my attendance would definitely not suffice.
So mainly i am unsure if somehow a company hires me, i would be able to start immediately. I heard that there are interviews for job recruitment after which the candidate is binded with an agreement to do some months training followed by permanent working after college completion.
This type of agreement is very much suitable for me, since from what my friend tells me, trainings can be lenient and understanding regarding exam preparations nd stuff.
So what do company usually chooses? Binding a fresher on immediate working basis or do they consider graduate completion?
Also, i suck at competitive coding. Do i need to polish myself on that or some company is willing to give me chance on the basis of my other skills 🙈(okay, no kidding , that's a serious question. I need to either work on getting better in competitive or build more apps based on that)
3.) ANDROID OR EVERYTHING? From what i have heard, working as a professional fresher is more like being an allrounder than being a domain specialist. But as i already stated, i really dig android and that's no small framework. I may di other stuff too, but won't interest me nd my output might be less efficient than expected.
So freshers can really be asked to do any stuff? Or can i still be in the area i like being into?
4.) COMPANY OR START-UP? Yeah, this is a general debate starter. Ignoring the business side of the conversation ( job safety vs more salary, experience, etc) the thing that's most important for me is the presence of a team. I want someone to assign me a task, whose vision i could follow, from whom i could learn, and some other people who are supportive and doing the same amount / similar work that am doing . This is so much import8 for me that i can easily ignore other factors for a better team. I once took a call from a startup ceo who hired me, a 2 month old android beginner at that time, as the "lead android developer"
But if am being on a team where i am supposed to do any random stuff that is assigned, then obviously this whole point of "visionary, helpful leader, guiding team, "etc goes moot9 -
By far it is my current project of building the industry leading CMMS (no it's not a typo, it's really CMMS). Everything from in office time management, to tracking when techs go on site, to detecting what are in pictures when sent back from our app (also my project), to sentence building, to smart auto-dispatching.... I mean this list is just endless of the features compiled in the application for just a call center. When I took the job I never knew facilities maintenance took so much and I never thought it would be this efficient.2
