Was lead developer at a small startup, I was hiring and had a budget to add 3 new people to my team to develop a new product for the company.
Some context first and then the rant!
Candidate 1 - Amazing, a dev I worked with before who was under utilized at the previous company. Still a junior, but, she was a quick learner and eager to expand her knowledge, never an issue.
Candidate 2 - Kickass dev with back end skills and extras, he was always eager to work a bit more than what was expected. I use to send him home early to annoy him. haha!
Candidate 3 - Lets call him P.
In the interview he answers every question perfectly, he asks all the right questions and suggests some things I havent even thought of. CTO goes ahead and says we should skip the technical test and just hire the guy, his smart and knows what his talking about, I agree and we hire him. (We where a bit desperate at this stage as well.)
He comes in a week early to pick up his work laptop to get setup before he starts the next week, awesome! This guy is going to be an asset to the company, cant wait to have him join the team - The CTO at this stage is getting ready to leave the company and I will be taking over the division and need someone to take over lead position, he seems like the guys to do it.
The guys starts the next week, he comes in and the laptop we gave him is now a local server for testing and he will be working off his own laptop, no issue, we are small so needed a testing stack, but wasnt really needed since we had procedures in place for this already.
Here is where everything goes wrong!!! First day goes great... Next day he gets in early 6:30am (Nice! NO!), he absolutely smells, no stinks, of weed, not a light smell, the entire fucking office smells of weed! (I have no problem with weed, just dont make it my problem to deal with). I get called by boss and told to sort this out people are complaining! I drive to office and have a meeting with him, he says its all good he understands. (This was Friday).
Monday comes around - Get a call from Boss at 7:30am. Whole office smells like weed, please talk to P again, this cannot happen again. I drive to office again, and he again says it wont happen again, he has some issues with back pain and the weed helps.
Tuesday - Same fucking thing! And now he doesnt want to sign for the laptop("server") that was given to him, and has moved to code in the boardroom, WHERE OUR FUCKING CLIENTS WILL BE VIEWING A DEMO THAT DAY OF THE PRODUCT!! Now that whole room smells like weed, FML!
Wednesday - We send P a formal letter that he is under probation, P calls me to have a meeting. In the meeting he blames me for not understanding "new age" medicine, I ask for his doctors prescription and ask why he didnt tell me this in the interview so I could make arrangements, we dont care if you are stoned, just do good work and be considerate to your co-workers. P cant provide these and keeps ranting, I suggest he takes pain killers, he has none of it only "new age" medicine for him.
Thursday - I ask him to rather "work" from home till we can get this sorted, he comes in for code reviews for 2 weeks. I can clearly see he has no idea how the system works but is trying, I thought I will dive deeper and look at all of his code. Its a mess, nothing makes sense and 50% of it is hard coded (We are building a decentralized API for huge data sets so this makes no sense).
Friday - In code review I confront him about this, he has excuses for everything, I start asking him harder questions about the project and to explain what we are building - he goes quiet and quits on the spot with a shitty apology.
From what I could make out he was really smart when it came to theory but interpreting the theory to actual practice wasnt possible for him, probably would have been easier if he wasnt high all the time.
I hate interview code tests, but learned a valuable lesson that day! Always test for some code knowledge as well even if you hate doing it, ask the right questions and be careful who you hire! You can only bullshit for so long in coding before someone figures out that you are a fraud.16 -
I have made this RGB LED tie. One of my friends and me had the idea at 2 am and now it has come to reality :D
It runs on an Arduino nano, 8 rgb leds and is powered by a 9V battery.
I have prom tomorrow ('abschlussball' in german) I probably won't wear it during the official part but definitely at the party after prom.
The current animation is a bit too fast (I was listening to hardstyle while coding it) for the music they will play tomorrow at the party so I still have to make a slower one.
Tell me what you think about it :P28 -
School principal : P / Me : M / Interviewer over Skype : S
P. I recently heard you run a software club in our school.
M. Yes. (started from March)
P. Well, one software community seems that he found you somewhere, and asked me if we can do a quick interview.
M. Sure. What is it?
P. So he will connect to skype.
M. Let's start then...
*A few moments later...*
M. Wwwwhhhhaaaaattttttt?
P. Calm down! What's the problem?
M. How can I have more than 5 years of android development?
S. Ok. Recorded. Next question.
M. (uhhh)
*A few moments later...*
M. What? Why in the heck do I use subversion?........
Yes... Ah... Ummm....
No! Why should i make a gui client for subversion?
*A few moments later...*
S. Do you have hacking experience?
M. Of what? I know hacking is illegal here..
S. Like... Anything!
M. Do YOU have an experience?
S. Yup.
M. What?
S. Google.
M. How?
S. (silence) Ok. Let's move on.
M. (wtf is this guy)
*A few moments later...*
S. Okay. We were about to hire you but you didnt met our job requirements.
M. ......What? What was the job?
S. Web developer Intern
M. I got no questions regarding "web".
S. I know devs should be great at all things.
M. Shut the hell up. What company are you?
S. (says something)
M. (Searches in google) Doesnt come in search results.
S. Where did you searched it? (trembling voice)
M. (Searches in naver, search engine of korea) Nothing. Are you sure you are a company?
S. (ends call)
Hate these fake interviews. And i have no idea how they found my school
I never wrote my school anywhere.12 -
This facts are killing me
"During his own Google interview, Jeff Dean was asked the implications if P=NP were true. He said, "P = 0 or N = 1." Then, before the interviewer had even finished laughing, Jeff examined Google’s public certificate and wrote the private key on the whiteboard."
"Compilers don't warn Jeff Dean. Jeff Dean warns compilers."
"gcc -O4 emails your code to Jeff Dean for a rewrite."
"When Jeff Dean sends an ethernet frame there are no collisions because the competing frames retreat back up into the buffer memory on their source nic."
"When Jeff Dean has an ergonomic evaluation, it is for the protection of his keyboard."
"When Jeff Dean designs software, he first codes the binary and then writes the source as documentation."
"When Jeff has trouble sleeping, he Mapreduces sheep."
"When Jeff Dean listens to mp3s, he just cats them to /dev/dsp and does the decoding in his head."
"Google search went down for a few hours in 2002, and Jeff Dean started handling queries by hand. Search Quality doubled."
"One day Jeff Dean grabbed his Etch-a-Sketch instead of his laptop on his way out the door. On his way back home to get his real laptop, he programmed the Etch-a-Sketch to play Tetris."
"Jeff Dean once shifted a bit so hard, it ended up on another computer. "6 -
While I'm in pause time with my colleagues and reading on wiki how, the boss comes to me and asks:
Boss: what are you reading?
Me: how to Quit Your Job Graciously 😊
Boss: 😐

One of the biggest e-commerce site's here in Sweden like to generate hundreds of thousands of sessionfiles every day.
That slows down their website alot, and the poor server is struggling hard.
They asked me if I could do something about it. So I mounted the catalogue with sessionfiles on a tmpfs volume. And suddenly the site is much faster. I guess storing sessionfiles directly into RAM solved it :P
And yes, they are aware that a restart of the server removes the files.8 -
Being one of the top devs (and a good student admired by most lecturers) at college, my most humbling experience was when I joined my first job. I thought I knew SQL, I thought I knew C#. I realized in the first week, the thing I didn't know was "I don't know jack".
Thanks to a couple of great mentors (it took a few of them to bring me up to speed :P), I learned that the more I learn something, the more I will realize how much more there is to learn. I used tools to create storyboard animations in WPF, and my mentor would write it all in XAML! I'd write messy SQL and the other mentor just reduces it to a couple of elegant lines. They were like tech gods to my college self, all while being humble and friendly.
They also imbibed in me a sense of responsibility to carry on the culture of mentoring my juniors, which taught me much more than just the technical side of our profession.3 -

One month ago. By email.
Boss: so, this client A has a problem with one of our devices and he believes that it's a bug in the software.
Me: all right then, what happens?
Boss: well, he says that the parameter P in the option menu does not changes the device's behaviour as it is supposed to. I'll forward you his mail. You will find attached an excell file with the results of his test performed with and without the parameter active.
Me: < read mail, read excell file > well, boss, his tests are performed in completely different conditions, how could he expect to infer a meaningful results from this?
Boss: damn, you are right. Send him a test plan and follow up.
Me: < send detailed test plan >
No answer in a week. Then...
Client: hi, there, I made this tests, I attached the excell with the results, can you check the software now?
Me: < read another bullshit filled excell file with none of the suggested test performed >
You know what? Just download the procedures you are using from the device and send them by mail, specifying the software version you are using so we can perform some tests here in the lab and get yo a solution asap.
No response. For a MONTH.
Super Boss: client A still has his problem, how could possibly be that it takes more than A FUCKING MONTH to solve his issue??
Me:...4 -
POSTMORTEM
"4096 bit ~ 96 hours is what he said.
IDK why, but when he took the challenge, he posted that it'd take 36 hours"
As @cbsa wrote, and nitwhiz wrote "but the statement was that op's i3 did it in 11 hours. So there must be a result already, which can be verified?"
I added time because I was in the middle of a port involving ArbFloat so I could get arbitrary precision. I had a crude desmos graph doing projections on what I'd already factored in order to get an idea of how long it'd take to do larger
bit lengths
@p100sch speculated on the walked back time, and overstating the rig capabilities. Instead I spent a lot of time trying to get it 'just-so'.
Worse, because I had to resort to "Decimal" in python (and am currently experimenting with the same in Julia), both of which are immutable types, the GC was taking > 25% of the cpu time.
Performancewise, the numbers I cited in the actual thread, as of this time:
largest product factored was 32bit, 1855526741 * 2163967087, took 1116.111s in python.
Julia build used a slightly different method, & managed to factor a 27 bit number, 103147223 * 88789957 in 20.9s,
but this wasn't typical.
What surprised me was the variability. One bit length could take 100s or a couple thousand seconds even, and a product that was 1-2 bits longer could return a result in under a minute, sometimes in seconds.
This started cropping up, ironically, right after I posted the thread, whats a man to do?
So I started trying a bunch of things, some of which worked. Shameless as I am, I accepted the challenge. Things weren't perfect but it was going well enough. At that point I hadn't slept in 30~ hours so when I thought I had it I let it run and went to bed. 5 AM comes, I check the program. Still calculating, and way overshot. Fuuuuuuccc...
So here we are now and it's say to safe the worlds not gonna burn if I explain it seeing as it doesn't work, or at least only some of the time.
Others people, much smarter than me, mentioned it may be a means of finding more secure pairs, and maybe so, I'm not familiar enough to know.
For everyone that followed, commented, those who contributed, even the doubters who kept a sanity check on this without whom this would have been an even bigger embarassement, and the people with their pins and tactical dots, thanks.
So here it is.
A few assumptions first.
Assuming p = the product,
a = some prime,
b = another prime,
and r = a/b (where a is smaller than b)
w = 1/sqrt(p)
(also experimented with w = 1/sqrt(p)*2 but I kept overshooting my a very small margin)
x = a/p
y = b/p
1. for every two numbers, there is a ratio (r) that you can search for among the decimals, starting at 1.0, counting down. You can use this to find the original factors e.x. p*r=n, p/n=m (assuming the product has only two factors), instead of having to do a sieve.
2. You don't need the first number you find to be the precise value of a factor (we're doing floating point math), a large subset of decimal values for the value of a or b will naturally 'fall' into the value of a (or b) + some fractional number, which is lost. Some of you will object, "But if thats wrong, your result will be wrong!" but hear me out.
3. You round for the first factor 'found', and from there, you take the result and do p/a to get b. If 'a' is actually a factor of p, then mod(b, 1) == 0, and then naturally, a*b SHOULD equal p.
If not, you throw out both numbers, rinse and repeat.
Now I knew this this could be faster. Realized the finer the representation, the less important the fractional digits further right in the number were, it was just a matter of how much precision I could AFFORD to lose and still get an accurate result for r*p=a.
Fast forward, lot of experimentation, was hitting a lot of worst case time complexities, where the most significant digits had a bunch of zeroes in front of them so starting at 1.0 was a no go in many situations. Started looking and realized
I didn't NEED the ratio of a/b, I just needed the ratio of a to p.
Intuitively it made sense, but starting at 1.0 was blowing up the calculation time, and this made it so much worse.
I realized if I could start at r=1/sqrt(p) instead, and that because of certain properties, the fractional result of this, r, would ALWAYS be 1. close to one of the factors fractional value of n/p, and 2. it looked like it was guaranteed that r=1/sqrt(p) would ALWAYS be less than at least one of the primes, putting a bound on worst case.
The final result in executable pseudo code (python lol) looks something like the above variables plus
while w >= 0.0:
if (p / round(w*p)) % 1 == 0:
x = round(w*p)
y = p / round(w*p)
if x*y == p:
print("factors found!")
print(x)
print(y)
break
w = w + i
Still working but if anyone sees obvious problems I'd LOVE to hear about it.38 -

Today I:
Me: "You wrapped 2 p tags and one div inside a button tag....why?"
Other dude: "What do you mean why?" * in condescending tone

To make things short. My manager told me I have to try harder to not speak to people in intimidating ways.
In all fairness...mr "associates in programming with 0 css experience" WAS condescending when I asked him why he did what he did.
The little shit earned it. And he will probably think twice about his damned tone when speaking to me.29 -

Gaming anytime!
The reason I become intrested in computers was gaming.
Given I started out as a game dev, playing games helps me think more about it and imporve my skills.
Also sometimes it reduces my productivity :P3 -
Where I work, in our database, we use 3 to indicate true and 7 to indicate false and 0 is true but null is false
In another table, we use 'P' to indicate true and 'I' to indicate false and 'Y' is also false and null is false
And the most used table, we also use 'Y' to indicate yes and 'N' to indicate no, but null is also Yes.
We also store integers as varchar in a live table, but stays an integer in all the other tables. I hope I'm not there when the number of digits exceeds the varchar limit.
These are all live and used in production all created by my boss, the head of IT.8 -

P = Person
P:Hey Can you build me a POS system for free?
Me: Yea whatever. (because... immediate family member)
P:Ok Great.
Me: *starts working on it.. almost done with inventory control and layouts in one night*
P: When will it be done? and I need it in a full screen window not a browser!!
Me: Soon..and I have not worked in ASP yet. So it will be a full screen browser app.
P: Aww you cant do it fast? You are not skilled enough??? Poor you, you are not good enough. I can do it in a few hours. Just write a C program which stores entries in a txt file. I dont want sql shes-que-el on my system. You dont want to use .txt because it will be harder for you. Poor you.. no skill.
Me: *raging to a level where i turn into kryptonium and burn superman to death but still keeping my calm* You will get it when you get it. Period
Inner Me: GO FUCK YOURSELF. IM DOING THIS FOR FREE SO THAT IT HELPS YOU OUT. NAGGING ME WONT HELP YOUR CAUSE ONE BIT. GO FUCKING LEARN HOW TO CODE YOURSELF AND MAKE IT YOURSELF OR BUY IT FOR A FUCK TON OF UNJUSTIFIED MONEY. IM GIVING YOU A BEAUTIFUL LAYOUT, GREAT APPLICATION ARCHITECTURE USING LARAVEL AND GREAT DATABASE DESIGN WHICH WOULD BE SCALABLE AND PRODUCE MEANINGFUL REPORTS. WHY THE FUCK WOULD YOU PREFER A .TXT FILE OVER A WELL DESIGNED DATABASE. WOULD YOU FUCKING OPEN THAT HAMSTER CAGE OF A BRAIN OF YOURS WITH A KNIFE OR A SCREWDRIVER?
IF ITS THAT EASY FOR YOU GO FUCKING DO IT YOURSELF AND STOP BOTHERING ME. I AM TAKING MY TIME OUT FROM FREELANCING TO HELP YOU OUT. I COULD BE SPENDING THIS TIME ON OTHER PROJECTS WHICH WOULD GET ME SOMEWHERE. THE ONLY FUCKING REASON IM DOING IT BECAUSE I MIGHT BE ABLE TO RESELL THE POS (PIECE OF SHIT) TO OTHER PEOPLE IN FUTURE AND MAKE MY SHARE OF UNJUSTIFIED SHIT TON OF MONEY.14 -

I had a professor in college who was "the expert in java programming language". He had a unique way of teaching.
P: So you save your java file and run this command.

Man in the event of some newcomers to the development game, those that will mostly work in the web domain or sys admins that are in training I want to offer some small advice:
Do not neglect vim
I know it might be a bitch to use at first. And I will never use it as a replacement to vs code. But fuuuuuck me I cannot count the number of times that vim wizardry has helped me when dealing with servers when dealing on a machine with windows and nothing but putty.
The thing is a lifesaver yo, and it makes for an impressive show when doing something in front of senior executives.
Learn it, love it, live by it
And exit is :q, save is :w, to copy and paste is :v then surround the text and then y to yank it and p to paste it.
:vsplit and :split are your friends and to move around splits is ctrl w and direction.
Good luck my friends. Stay classy.9 -
Currently developing an android app that is a clone for an existing iOS app. Sadly all the PMs and POs (the P-M/O fraction) at this firm are somehow iPhone users.
So every time we implement stuff according to android guidelines some PMO comes around and asks: "why doesn't this look/work/smell like in iOS?"
Somedays I feel like crying...6 -
Near the end of a massive (1,000 user bridgeline) conference call today:
[ P = presenter, RCn = random caller n ]
P: ...so, does anyone have any other questions they'd like to---
RC1: Hey! Yeah, I'm still on this STUPID call right now... I dunno, we've been in here for like 30 minutes already - The guy came by the house to talk about it, but I couldn't get off this STUPID call - I think they said it would be around 800 dollars...
[ P, RC1, RC2, RC3, RC4 all overlapping ]
P: Um, we can hear you-
RC2: Dude, mute your phone!
RC3: As the presenter, you can mute that guy from the web UI-
P: Yeah, I can't find him in the attendee list; it's so long-
RC3: -Right-click on his name and select "mute line"-
P: I know how, but I can't find him on the list.
RC3: Find him on the attendance list on the right side-
P: [ louder and louder ] Yes, I know - but I can't find him in the list-
RC4: Should someone call an operator?
RC1: -so I figured we'll probably need to call Jerry and see what he says. I'll call him if I can ever get off this ridiculous, STUPID call - They are all talking at once on there now and no one can understand anything!
[ This went on for about 5 solid minutes, finally ending with... ]
RC1: I'm just going to drop this STUPID call and call Jerry for us. This thing was a total waste of time. [ boop-beep ]
[ long pause ]
P: OK, so now that is over, does anyone have any questions they'd like to discuss?
[ At least 10 people un-mute and overlap questions ]

Above everything else, the funniest part to me was his repeated, over-the-top insistence on how "STUPID" the call was.

Dear external developer dumbass from hell.
We bought your company under the assumption you had a borderline functioning product and/or dev team. Ideally both
For future reference expect "file path" arguments can contain backslashes and perhaps even the '.' character. It ain't that hard. Maybe try using the damn built in path parsing capabilities every halfway decent programming environment has had since before you figured out how to smash your head against the keyboard hard enough for your shitty excuse of a compiler stops arguing and gives in.
I am fixing your shit by completely removing it with one line of code calling the framework and you better not reject this.
This is not a pull request ITS A GOD DAMN PULL COMMAND.

I told my boss that I felt my job filled the work description of a “senior engineer”. He asked me to write down a few sentences why I thought so, so he could suggest a title change to the board. I did and two months later it went through! Got a 15% increase! :)
I also was kind of “head hunted” for a different job a few weeks before, but hadn’t received any real offer from that company yet. This got known to my bosses boss and he urged me to talk to my boss before making any decision. I think that also helped... :p
I’m now the only senior engineer in my department, just because I take on a little extra responsibility and do a little more than what is expected of us.3 -
Discovered this awesome community some months ago, and I've finally decided to make an account :D
Guess I should write a rant now.
We were initially a team of 2 to do a 'simple' app with AngularJS, NodeJS and Kendo UI in 2 months.
We had some problems with it, mainly because I'm 'in charge' of a big Java web application filled with legacy code and in process of a 'big change that was planned to be deployed for all users yesterday', and my coworker (also the project analyst) was still learning how Node and Angular work. And I'm not going to lie, I'm still learning new things everyday.
Situation 1 month after our start: coworker fired (due to offtopic reasons), replaced by a younger girl, and me still doing changes in the Java webapp.
Thank god I work better when under big pressure :p2 -
Just finished our BIG update including a big change in the backend (PHP => NODEJS). So I hope our users will enjoy this one because we are not yet public and our competitor get a lot of clients each day but if we compare our product to their product: Ours is responsive as fucked and have much more stability but less fonctionnalities so we have to add more fonctionnalities before releasing our product to the public. I hope we will be able in a few weeks! With only me and my back-end dev (My employee and friend at the same time) to work on it and they have 2 more devs to their team to use Bubble.. (They are now 6 or 8 devs (wannabes and using a drag and drop website) in total vs 2 (us) real programmers).
A well deserved night of sleep :P3 -

Today a few friends got together and built my gfs new computer. I just watched because.... I'm a hardware n00b :p
Anyways, it took them about 2 hours building all the stuff together and now we're done installing Windows from via disc. The problem is, it's 2015 windows. So we're updating.
And it already takes more time to update windows than building the actual computer.
Nice!

After two years... I finally was able to quit my job.
I'm finally in a cool job, with a great team, with a cool project (from scratch! )
I have to learn Spring and Vue.js, knowing that I never tried any framework of these languages. But I really want to make it, I didn't suffer for two years, just to be beaten by a stack :p
Thanks for the ones who commented on my rant a few months ago, telling me to keep hoping for a better job. I got hired three days after the end of my previous contract, and I couldn't feel better now!9 -
It's my first 'rant' so be kind :P
When I started my studies a already knew some very basic programming stuff. I went to the exercises with another dude I met. We always joked about the tasks we had to do and did other things while the others tried to fix bugs in their code. After the semester ended he asked me whether I want to work part time at his mother's office. I went to the interview which was weird because I have never been to one before but got the job straight away. I'm in my fourth year of working there because the team is awesome.5 -

I promoted duckduckgo to friends on Facebook and got them in a discussion about it. People generally are fairly receptive (with one annoying uncle pointing out the irony of posting it on Facebook xD).
One mentioned it was difficult to switch because Google was "just there", so I pointed to instructions on how to make it default.
Also enticing them with theme changes.
Feels good. Next to teach them how to use proxies :p
meta rant: I categorised this as a rant/story, mainly because it is related to tech, should I have just done "random"?29 -
I'll repeat what I wrote in an answer in another rant because I think it made a good story (I just realized it after writing it :p) :
I met a guy in my school who was the best of the school : I mean, he jumped over the first two years of the school (and he started from scratch, he never had programmed before).
I went to ask him how he got enough motivation to make all the two years projects in one and he told me something that made me understand why he was so good : "I'm fucking lazy, so when I code, I code something that I would use for a very long time, tools that will be useful in next projects".
By doing this, all he had to do in end-year projects was to assemble what he already had done to make the program. He had perfectly working tools that were awesome. So, he never had to work more than 10 hours a week after doing this.4 -
My manager is instructing my team to add a feature that can only be enabled for users by running an update script in the database.
When I argued that it's not really "complete" if it can't be turned on without someone going into the production database, I was told that not only is it complete, but they plan to have our non-technical customer service enable it for customers if the customer requests it...
Apparently giving everyone and their brother write access to prod is a good idea, but implementing a checkbox is a "waste of time and would cost too much money".
Probably going to float my resume... :-p2 -
Goddamn it.
I extended my contract at a company, also switched from 8 hrs to 4 hrs. Me not knowing exactly when the switch is happening, i thought i have to work 8 hrs till the first contract is over (middle of the month ish). Well, huge nope, it changed in the beginning of september. I managed to do 40 hrs of overwork.
They don't pay overwork. Fck this.
Well at least i can stay home more :P6 -
I hacked a browser game a few years ago for fun and the exploit I found and used was basically this:
<$php
$f = $_GET['f'];
$p = $_GET['p'];
$f($p);
So it was possible to pass a function and it's parameter in the URL to the server. The author used this to include() sub pages. I to highlight_file()s.2 -
DO !!!NOT!!!!! USE 'X' AND 'P' TO 'CUT AND PASTE' A LOT OF LINES ACROSS FILES IN VIM!!! HOLY SHIT I JUST PWNED MYSELF SO HARD I LOST SO MUCH CODE HOLY FUCK IT'S NOT EVEN FUNNY! WHERE DID AT ALL GO YOU ASK, WHY THE FUCKING REGISTER, OK LET'S CHECK THE REGISTER, COOL THERE IT IS, BUT WAIT, THERE'S ONLY LIKE 20% OF IT BECAUSE WE CUT A SHIT LOAD OF LINES AT ONCE, AND THE REGISTER OVERFILLED.... Ok let's calm down, doesn't Vim have a recovery option? Yes it does, but WAIT A FUCKING MINUTE, MY CHANGES ARE NOT IN THE SWAP FILE BECAUSE IT'S NOT LIKE VIM CRASHED OR ANYTHING, MY DUMB-FUCK-ASS WILLFULLY WROTE THE CHANGES WHEN I SWITCHED OVER TO THE NEW FILE, AND NOW, WELL THAT'S IT, YOU'RE DEAD KIDDO, YOU WROTE THE CHANGES TO DISK, NOTHING YOU CAN DO, AND I AM SO SCREWED I SPECIFICALLY MADE A DEVRANT ACCOUNT TO MAKE SURE NO ONE ELSE PWNS HIMSELF AS HARD AS I JUST DID HOLY FUCK16

Would be really nice if devrant had a built in plugin for our IDE's- kinda like a scroller menu on the side :P We could rant in the office without forgetting it later. I'd call it "real-time ranting".4

So I'm playing around with Node late at night and decide to make something of it. Made a real-time 2-way communication system with NodeJS, Express and Socket.io. The UI currently looks cheap, but it's clean. Open multiple tabs to see it in action.
You can also send private messages by typing /p username message. I could add authentication here and also connect it to MongoDB.
Any other ideas or reviews? Also any other ideas for Node projects? Thank you.

Got a math exam tomorrow but learning about it-security and pen-testing is a lot more interesting.
Building a remote for the projectors in your school can also be a source of fun :P2 -
Been programming Java for a few weeks now, and WTF is this, Java?!
"Example".equals("Example")
What is wrong with the form that a dozen of other languages use?
"Example" == "Example"
P. S. If you don't know Java, the latter one compares for the type of objects and always returns true in this case.15 -

After 3 years of being the first in and last to leave, of getting other people's work reassigned to me - P can't complete it on time, G doesn't like the user, A refuses to work on that module, etc... I finally blew last Sept.
In the span of 2 days, my boss brought me into a project 1.5 years in (she doesn't trust P to do the coding) and expected me to be up to speed and coding in a couple of days, told the functional dept that I would cover for one of their guys on vaca for three weeks and assigned me to take over a HUGE project from one of the other functional guys who wasn't getting it done. So basically I'm now doing Ps job AND supporting another department AND taking control of a large project from another department. I'm the idiot working 14 hour days while they're all leaving on time or enjoying their 3 week vaca to India.
I lost it. It's bad enough filling in the gaps in my own department but when I'm now taking on work for other departments, that's where I draw the line. I sent my boss my resignation - just could not take the inequity in the work load.
I'm still working here - my boss ended up hiring a consultant to handle the functional project and told the functional group to find their own vacation coverage. She's also monitoring workloads much closer now. I still habe an ongoing issue with having to complete other peoples work for them but I'm not working OT to do it. So speaking up helps. So does quitting.2 -
Spent 4 hours debugging a “button” styling, worked fine locally but not on production.!
After striking out “cache” issues, “browser” versions, “fonts”, “sass errors” the error was with a stupid chrome extension that appended a css class attribute to the “HTML” tag 😡
And the other developer thought that was a part of what was written in the code !!
Hate these kinda plugins that manipulate the DOM 😪
P S the plugin is "Grammarly".2 -
Another chapter in the life of a novice programmer:
I work a lot with PHP and Laravel, but I feel I'm ready for different challenges. I spent all of last week searching online and getting advice on what language I should focus on next. My two first options were Java and C... So naturally I ended up choosing Python :P
At least I'm certain now and already started studying and wow, I think I made the right choice!3 -
Oh man where to start:
Not wanting to use LINQ because he did not wanted to "download external dependencies"
Not wanting to use prepared statements on their php sql code, and refusing to use pdo because they will "always use mysql"(moved to postgreSQL shortly after I left)
For some reason including a php file that only had ?>......thats it....only ?>
Use c++ but refused to learn oop and use structs for everything, importing stdio.h and printf everything.....like really?
Maybe just nitpicking, but refusing to use the recyclerview pattern on am android app. The implementation was faster after I made the change.
Importing a library for promises instead of using the ones already in the language(JS)
Changing the style of aaaaall p tags instead of using classes as well as refusing to use divs in place of p tags...well...fuck

How Bad I'm at frontend Development: about 3 year ago i accidentally wrote </from> instead of </form> while working on the frontend of a website, everything just went bonkers. Took me 10+ hours to realize my mistake.
In my opinion frontend devs are real hero they have to learn multiple frameworks, and make website respinsive and work on IE at the same time. Idk Why the fuck clients still want their website to work on IE (fuck you Carl, your users are of age group 15-22 they don't even know wtf IE is)
P. S. At that time i didn't knew HTML validators are a thing.6 -
My first contact with an actual computer was the Sinclair ZX80, a monster with 512 bytes of ram (as in 1/2 kbyte)
It had no storage so you had to enter every program every time and it was programmed in basic using key combinations, you could not just write the commands since it did not have memory enough to keep the full text in memory.
So you pressed the cmd key along with one of the letter keys and possibly shift to enter a command, like cmd+p for print and it stored s byte code.8 -
I'm currently working in a web application project with multiple environments for testing, and we need to give support to all browsers.
So when a 'defect' is iddentifyed by someone, we make sure we know all the previous constraints to solve it quicker.
One of these days, this "tester" comes to us:
Tester: There is a deffect in this X screen.
IT: Ok. Can you tell me what browser you were using in the test?
Tester: The same as you. "H T T P : / / localhost:8080"

I like coding in a way that anyonr who comes into my code base can understand whats going on. That way more people can maintain the code base.
However, I HATE having people in my code base. Since they leave shit undocumented, and have 10 variables called "data" "items" "o" "p" and another 20 methods called "processData" "convertItem".1 -
With limited Internet in 92 :P I read magazines and did line by line from the books. From Atari 520 ST, to vb6, then into PHP, C++ and C#, it's fully been a ride of self learning.
I envy the new generation with the massive amount of online learning sites. At age 36, been programming since I was 12. What an advantage young kids have today!1 -
Ahhhhhh anyone here use yED? I don't know how i even worked out diagrams before this. For the past couple years this has been my choice diagramming tool <3
Top image is before, bottom is after a single click. I just join boxes and let it work it out at the end. Then obviously do some adjustments to read how I like but seriously makes it easier to trial various layouts. I even make stuff in yED before recreating in something like Visio, if need be.
If anyone got another diagramming tool they like to use, post below (trying to add new stuff to my toolbox lol)
EDIT: Ahh, tried but you can't see the lines after the image gets compressed after upload (and DarkReader on chrome isn't exactly helping :p).9 -
When you start a new project with 2 more developers. You see their CVs and they look experienced.
(Fast forward one month....)
You realize you are the most experienced one and they are waiting for you to guide and mentor them.
The worst of all I thought I was going to learn from them because I still am not ready to mentor other people.
Aaaaaand now I am panicked.
I miss the time where I used to sit in my corner, do the tasks that was given to me and that's all. Now I have to code, build documentation, assign tasks, etc. I am not ready for this. I never asked for this. I just wanted to be a developer. :( :P2 -
If you are one of all those awesome developers and hackers and I only understand 20% of your rants then props to you and keep scrolling :-D
But if you are a young developer, fresh grad or just learning programming I have an idea, how about a mentor?
This literally just pop in my head right now while cleaning my kitchen!
I'd be learning along your side and also having lots of fun! I don't have any formal experience providing mentoring but have some education credits and patience.
I'm gonna stop the sales pitch because it's annoying even me! but Idk, i just thought that maybe there's someone else out there interested in mentoring services :P3 -
I want to share one very interesting incident -
Once upon a time, ( 9 yrs back ) I got my first PC. It had Windows XP.
After using it for 1.5 hours, I realised there are some files in C:
I said to myself, my hard disk capacity is 150GB but why some files exist in C:?
Within next 4 seconds, I issued a command to delete all files in C:
The rest you can predict :p1 -

Years ago at school I recreated the UNIX logon screen. With this, I collected login credentials and then displayed a message that the dish gets formatted now. To make it more realistic I had a progress bar and generated random file access in the disk, so the LEDs flashed. Loved it and even the sysadmin could see the fun (and educational background :P)

Around 2 years ago, I had first discovered DevRant.
I was an intern in a startup then, and I was working on ElasticSearch. I remember making rants about it. The internship ended. So did my relationship with ElasticSearch.
This week, a new intern joined our organisation (a different organisation). He was assigned the task of deploying ElasticSearch, with me as his mentor. All was going good, we migrated data from MongoDB to ElasticSearch and all.
Back then, I used to curse the team lead (leading a team of interns mostly), for not helping me properly...
I wanted a publicly accessible dashboard, since we can't really see the Kibana dashboard with SSH :P... So, we implemented user authentication using X-Pack security. And here we are, stuck... Again... I'm unable to help the intern. The World has come to a full circle.
PS: I have to just guide him while doing my own User Stories.

Man, people have the weirdest fetishes for using the most unreadable acrobatic shell garbage you have ever seen.
Some StackOverflow answers are hilarious, like the question could be something like "how do I capture regex groups and put them in a variable array?".
The answer would be some multiline command using every goddamn character possible, no indentation, no spaces to make sense of the pieces.
Regex in unix is an unholy mess. You have sed (with its modes), awk, grep (and grep -P), egrep.
I'll take js regex anytime of the day.
And everytime you need to do one simple single goddamn thing, each time it's a different broken ass syntax.
The resulting command that you end up picking is something that you'll probably forget in the next hour.
I like a good challenge, but readability is important too.
Or maybe I have very rudimentary shell skills.5 -
While I was working on a university project with my team, a teammate asked me why the window of the program in my screen was bigger than in his. I simply answered him that his screen was a FullHD one that had a 1920x1080 resolution, while mine had a lower resolution, and he was like "Noo! This isn't a fullhd screen, it's not so sharp".
So I showed him the "1920x1080" sticker right below his screen, and him again "Yeah, it could have this resolution but definitely it's not a FullHD screen".
- Ok, as you say...
The same guy two days ago was talking about creating a GUI in C.
I told him that C was the wrong language to build programs with a GUI, although there's some very old libs that allow you to do that in 16bit.
And him again: "Ok but Linux (distros) do that and the UIs are great!"
- Do you think that all the fucking Ubuntu/Mint/any distro code is written in C??
The funny thing is the arrogance with which he says all these bullshits.
P. S. We are attending the 3rd year of Computer Engineering.6 -
We won a competition - it was the first time he has taken part on it - and we had 1. place (me :p) and 2. place.
He was happy like a small kid, hung the certificate on the wall, made photos with our principal and the winners and we got in the newspaper xD4 -

Can someone explain to me why most design like apps are build in fucking electron. This is like the second time this week.
Me: *sees a super designy looking app*
Me: *Downloads and install*
Me: *Starts* * Slow startup*
Me: This has to be fucking electron again.
Me: *looks in resources folder* YES it is.
I'm not hating on electron. Its just that native apps are so much faster but way more ugly :P
BTW, apps were laverna and hyper5 -
Omg how stupid some people are... Today at my university I used the first time one of the computers in the computer room and there is a portable Firefox installed in a shared space on the computer and that is also where it saved settings etc. So this is the same for every user on that particular computer.
And when I checked the security settings I found that about 10 different accounts were saved and accessible with website username and password.
So of course the shared space Firefox is bad, but you still shouldn't save you password on a public computer :S
PS: If anyone needs a webmail account or an account for the german university network contact me :P4 -
This is not really the reason I got these parts, but I just had them lying around and have been following the project for some time... so why not? Haha. I was also thinking it might be cool to set these up to auto-disrupt known AP names that would be issued by companies most responsible for the dismantling of Net Neutrality. Like just make them in a dirt cheap throwie form-factor and let the companies deal with pissed off customers for a few days until the battery dies (thinking the little generic LiPo’s that cheap quadcopters use would give a few days if attacking sporadically and using the ESP’s sleep function). Just riffing here... ;P ;D2

Customer has asked me to recreate a dashboard they use with a bunch of data, charts, etc.
Problem: The screenshots they sent me... almost everything is illegible. The fidelity of the screenshots themselves is just fine.
It's that their dashboard they have is straight unintelligible. The charts are all smashed up, scale is off, most data ... you can't even tell what it is.
On one bar chart there's just one bar, no x or y scale indicators ... and a random dot in the bar... what even?
Apparently they love this dashboard but as far as I can tell they can't possibly be getting anything of value from it ...
It's like I can cook... but I can't make a recipe .. wrong ... just like someone else made it wrong from screenshots. :P -
How many times I went to sleep frustrated with a problem I couldn't solve and woke up the other day with the answer in mind :P

Love the topic, and I have multiple.
We were designing a frontend for a new application and we were using University lingo for the text placeholders. I forgot to remove one section in which the text stated "You are looking to enroll in the University of Deez Nuts", on another section I left "Click here cuh". Our manager at the time liked the design so much, but forgot to check for spelling or texts and as such sent the demo to our entire department. Everyone saw it, and while they all found it funny it could have seriously gone wrong. Thankfully our department VP had a pretty good sense of humor.....dude also knew exactly who it was from the start.
On another application, a director, who is a friend, asked for multiple items on a request form, during testing, I added text in Spanish (I am in Texas, but Spanish is pretty well known and spoken in the state) saying "Que bien chinga <Name of the Director>" which roughly translates to "<Name of the Director> is being annoyong" (but in a very Mexican spanish way)
I neglected to consider that the dude was probably viewing the admin board and checking the items as they were being added to the system and he called me not even 3 minutes later saying "You know I can see what you add right??"
All in all, I was pretty lucky because in any other places I would have been severely reprimanded :P
There are many more, but these came at the top of my head as the better ones. -
You know how my 'about' here says I create features from bugs?!? Well if you didn't before, now you do.. :P
Anyhow, today the most bizzare thing happened.. Customer played 'reverse uno card' on me..
Meaning?!
They reported a feature missing on uat env, when in fact I fixed a bug they have on prod..
Not sure how I should feel about this, but it sure made my day! (: I just hope they will not open a bug report for this missing bug..4 -

Hi guys,
Im a Software Engineer from Germany. I've just heard that delevopers are much better paid in the US compared to Europe.

I was once asked to create a fully secure chat system prototype (the ui didn't matter) in 2 days. We ended up building a client in python (which I wrote) and it kinda worked and a c# backend that didn't really work.
1 hour before we had to present the project to some high up management we decided that we couldn't fix the bugs in the system.
So I came up with a cool idea. Why not use ssh?
So I set up a bash script that writes to a file and tail -f that reads from the file. That way you could chat securely with another person.
I made it 15 minutes before the presentation with no Internet working :) they said it was hacky but a cool solution they saw that day :p I felt happy and that I had to thank Linux for being there for me2 -
yay or nay?
for who are wondering what is on the screen :

What's everyone's opinion when it comes to designing modern and/or minimalistic interfaces when using blur or gradients?
I see a lot of people who are hating blur used in UI elements and a lot of people praise the 'death' of gradients, what's everyone else think of these.
I personally love using blur in UI's and do like gradients if done correctly (not 2 colour gradients)
EDIT: I mean what's your opinion on blur and gradients not which one is better :-P12 -

MENTORS - MY STORY (Part III)
The next mentor is my former boss in the previous company I worked.
3.- Manager DJ.
Soon after I joined the company, Manager E.A. left and it was crushing. The next in line joined as a temporal replacement; he was no good.
Like a year later, they hired Manager DJ, a bit older than EA, huge experience with international companies and a a very smart person.
His most valuable characteristic? His ability to listen. He would let you speak and explain everything and he would be there, listening and learning from you.
That humility was impressive for me, because this guy had a lot of experience, yes, but he understood that he was the new guy and he needed to learn what was the current scenario before he could twist anything. Impressive.
We bonded because I was technical lead of one of the dev teams, and he trusted me which I value a lot. He'd ask me my opinion from time to time regarding important decisions. Even if he wouldn't take my advice, he valued the opinion of the developers and that made me trust him a lot.
From him I learned that, no matter how much experience you have in one field, you can always learn from others and if you're new, the best you can do is sit silently and listen, waiting for your moment to step up when necessary, and that could take weeks or months.
The other thing I learned from him was courage.
See, we were a company A formed of the join of three other companies (a, b, c) and we were part of a major group of companies (P)
(a, b and c) used the enterprise system we developed, but internally the system was a bit chaotic, lots of bad practices and very unstable. But it was like that because those were the rules set by company P.
DJ talked to me
- DJ: Hey, what do you think we should do to fix all the problems we have?
- Me: Well, if it were up to me, we'd apply a complete refactoring of the system. Re-engineering the core and reconstruct all modules using a modular structure. It's A LOT of work, A LOT, but it'd be the way.
- DJ: ...
- DJ: What about the guidelines of P?
- Me: Those guidelines are obsolete, and we'd probably go against them. I know it's crazy but you asked me.
Some time later, we talked about it again, and again, and again until one day.
- DJ: Let's do it. Take these 4 developers with you, I rented other office away from here so nobody will bother you with anything else, this will be a semi-secret project. Present me a methodology plan, and a rough estimation. Let's work with weekly advances, and if in three months we have something good, we continue that road, tear everything apart and implement the solution you guys develop.
- Me: Really? That's impressive! What about P?
- DJ: I'll handle them.
The guy would battle to defend us and our work. And we were extremely motivated. We did revolutionize the development processes we had. We reconstructed the entire system and the results were excellent.
I left the company when we were in the last quarter of the development but I'm proud because they're still using our solution and even P took our approach.
Having the courage of going against everyone in order to do the right thing and to do things right was an impressive demonstration of self confidence, intelligence and balls.
DJ and I talk every now and then. I appreciate him a lot.
Thank you DJ for your lessons and your trust.

I don’t know if I would call it a quirk of the language or serious abuse of it :P
But I managed to get a null ref exception when comparing a local int variable to an int parameter to the same function in C#.
Since a local or parameter of type in cannot be null and I compared the variables them self and dud not try to access any property on them (and no extension method or implicit case or similar) my first thought, along with all colleagues that chipped in to help, was that this should not be possible.
Turns out the method was called through reflection and in that part it injected null as the base object to call the method on.
Since local variables actually are referenced through the parent object this was what was causing the null ref.
That took some time to figure out.4 -
When I think "the fundamental problem", the closest thing that comes to my mind is "unsolvable problem". P =/!= NP is a fundamental problem, the theory of everything is a fundamental problem.
But we actually solved at least one such problem – the fundamental problem of cryptography.
The problem was "how to establish a secure connection over a non-secure channel?" Like you can't exchange the key, it'll be exposed by definition.
We solved it with a simple yet brilliant solution of asymmetrical cypher, that thing with public and private keys.
It's fascinating to think that people died in WW2 over this, there were special operations to deliver fresh deciphering keys securely and now SSH and HTTPS are no-brainers that literally everyone use.10 -
I just learned that you can use Android Device Monitor in Android Studio to take screenshots.
Until today I was using adb screencap -p /sdcard/filename, totally forgetting the filename, go through all the commands and see what fucking file name I used and do an adb pull. It was a lot of fucking work.1 -
Years ago when I was younger than currently I got this first summer job as help in IT departament to answer calls from distressed workers.
Once this lady calls that "her monitor went black" and she cannot work, so I have to get her a replacement. They got only this big heavy CRT monitors as replacements so I had to drag it to 4th floor (no elevator) from basement.
As I reached her it turned out that her monitor is fine, only the wallpaper was changed to black, that what she was meaning :p
Well, at least I got some exercise back then.1 -

I'm a C++ dev, but last month I was working in the vegetable fields to help my young brother and his business. And right now I'm going to sleep outdoor after my birthday party looking at the stars.
Free spirit is a good point dealing with free languages like C++ you know :D
Sweet dreams btw :p -
The # in C# could’ve been decided when they realize that you can draw the ++ of C++ diagonally and just extend the lines, or you may even think of it being ++++, and tile them up in a 2x2 way. If either is true, are they trying to imply that C# is superior to C++? :P6

I think I did it. I did the thing I set out to do.
let p = a semiprime of simple factors ab.
let f equal the product of b and i=2...a inclusive, where i is all natural numbers from 2 to a.
let s equal some set of prime factors that are b-smooth up to and including some factor n, with no gaps in the set.
m is a the largest primorial such that f%m == 0, where
the factors of s form the base of a series of powers as part of a product x
1. where (x*p) = f
2. and (x*p)%f == a
if statement 2 is untrue, there still exists an algorithm that
3. trivially derives the exponents of s for f, where the sum of those exponents are less than a.
4. trivially generates f from p without knowing a and b.
For those who have followed what I've been trying to do for so long, and understand the math,

I'm just writing and finishing the scripts for it now.

I work with content. More specifically I work on content migration and improvement.
We connect to many platforms and pull and push documents into it. This one time we had to connect to some outrageously expensive (6 figures) system which we obviously couldn't afford to buy just for testing. The client wouldn't give us a testing server either.
My literal warning: "We need a testing server because we're gonna push it until it breaks. Then we know the limit." Client: "nah it will be fine." Us: "I promise you the server will go down..." Client: "It's a stable system. You can test in your own folder on our server"
10 minutes later we had an angry client because the server crashed due to overload.
I'm not sure if I'm annoyed or amused :p -

TLDR;
How much do you earn for your skill set in your country vs your cost of living?
BONUS;
See how much I & others earn.
Recently I became aware of just how massive the gap in developers earnings are between countries. I'd love to calculate a fixed score for income vs cost of living.
I know this stuff is sensitive to some so if you prefer just post your score (avg income p/m after tax / cost of living).
I'm not shy so I'll go first:

Consulting / Short term: $30-$74
Pen Test: $1500 once off.
Pen Test Fixes: consulting rate.
Simple work/websites: min $400+
Family & Friends: Dev friends are usually free (when mutually beneficial). Family and others can fuck off, even if they can pay (I pass their info to dev friends with fair warning).
GENERAL INFO
Experience: 9 years

*Note: For integrity when calculating my cost of living I excluded debt repayments and only kept my necessities which are transport, food & shelter.
I really hope you guy's post your results, it would be great to get an idea of which is really the worst / best country to be a developer in.20 -
Struggling with Linux driver bullshit today. Trying to update the graphics driver completely hosed the networking, second monitor (HDMI), and I assume a bunch of other stuff. I tried using the Additional Drivers utility and it nearly made my system non bootable. So on my second computer I had to look up how to unfuck my machine using the command line. Yet another classy set of bullshit from Gnome. The driver for all this was trying to fix some java programs that show wonky depending upon where the window is on my second display. After unfucking the machine I found that resetting all the display settings for both displays magically fixed the java program fuckery. How the fuck? Literally setting things like display resolution, default display, moving virtual displays around. This bullshit somehow fixed display problems with java apps.
So I decided there is a perfect OS out there somewhere, but it isn't iOS, it isn't Windows and it isn't Linux. I decided to make the Perfect OS, or P-OS for short. Gonna use P-OS as a fake OS in my games I make. lol15 -
Since we’re adding new backronyms every day, I propose SIMPLE.
S - Spaghetti: write tapestry of code like a chef.
I - Interlinked: if the project has modules, they should all depend on each other (we are strongest when we can depend on one another).
M - Micromanaged: if the product owner doesn’t expect reports in the daily stand-up, do they even care?
P - Perplex: diversity for the codebase.
L - Lazy: Bill Gates once said “I choose a lazy person to do a hard job, because a lazy person will find an easy way to do it”, for example, without testing, collaborating with team members, or ensuring the feature works with anything else in the codebase.
E - Opinionated: because I believe E should stand for opinionated and everyone else will have to work around this with adapters. But E should mean Opinionated because Uncle Bab said so.6 -

I have multiple contenders ;)
Contender one:
A program used to sort emails.
We was in the process of moving from lotus notes to exchange and needed a way route emails to the right server internally.
Solution, a qmail to receive all emails, a script running by cron every minute to read the emails, check the recipient name to a list and resending to the right server. The script was written in php :P since that was the only way we at the time had to read an email into an object, it was run just like any other shell script :D
Contender two:
A multi threaded mail sender that fetch email addresses and content from a database and posted them through qmail using background execution and pipes to get the result back and then update the database, written in bash script.
Contender three:
A c program used in a similar way as in one but this time using dial up and uucp to fetch email and then drop these either into lotus notes or into a bbs for our customers to give them an email address. This was around 1993, so not to many isp’s offered email and not to many had internet anyway, dial up bbs was much more common.5 -
More masturbation with numbers.
If you take some product p,
and do
√p**(1/p)
and it's factors
a**(1/p)
and
b**(1/p)
you might find something interesting.
Take for example
a=21977
b=43331
p=a*b=952285387
(√p)**(1/p) = 1.0000000108551363
a**(1/p) = 1.0000000104986928
b**(1/p) = 1.0000000112115799
More often then not, a, b, or both, will share one or two of the most significant digits in the mantissa, as the root of p.
It doesn't always work, but it seems to be true more often than you might expect.
This is probably obvious in hindsight but I still think it's cool.
In some instances if you then do, say
sqrt(log(p, 1.000000010)), it comes pretty close to the original factors, but thats really hit or miss.8 -
When I was in University, there's a group project on web development. We decided to make a simple game.
Out of 5 students (including me), one was missing for the entire semester.
Another one don't know anything about any kind of programming. We asked him to write us a json file of characters' attributes. Taught him how and gave examples. Turns out that most data is missing.
Luckily the other two was great. Altogether, we covered frontend, backend and design. Finally we got the highest mark :P

It is time for my own dumbass's favorite pastime: not letting go on retro tech.
I am gonna build a small and complete RESTful web API with Vbscript and Classic ASP with errrthing thrown in this mfker including JWT authentication and i am gonna see how the idea of an ORM goes. I know that COM interop was a thing, dunno if it still is.
I am fucking bored. The graduate degree is killing me and I need a distraction.

So I was looking for a way to easily take android screenshots in a lossless image format, since my OEM only does jpeg.
Didn't want to install another adware and wound up with the adb shell screencap command since I need the pictures on my PC anyways.
But instead of a nice one-liner like
adb shell screencap -p > screenshot.png
I need 3 lines in a bash script.
Can we please just end the line ending wars?5 -
Heard a story about an interview taken by one of my teammates..
The guy had approx. 9 years of experience of full stack development having current exp in JS based work.

@dfox @trogus : Do we have a feature of auto complete @ mentions ? If not, there can be an elegant feature to provide drop down suggestions to mention / tag user in comments after we type @ in comments of any rant ( not all the users , but author of the rant and those who previously commented on that particular rant previously. For example, if I commented on a rant of dfox, and trogus also comments and types @, me and dfox will be in the drop down, tapping on which will select and tag that user on that comment ). I bet users will love this devRant update. Sorry for long post , I don't have any potato :p3

my fist job... i get to edit a c++ code written by a (mind you) programming company that they teamed with for the past(mind you again) 3 years ...
now just for starters, this code was edited by self taught coders that are really good engineers(they are really good), that didnt really know how the code worked before yet they still changed it, and it worked, how ever they wanted some changes.
i get the project files, and there is not one single comment describing what is happening... only code commented out... and no documentation what so ever were done....
so below are some of my comments that i wrote after i finished adding what i had to add, and fixing what i had to fix:

HELP ME OUT BRUTHA AND SISTUR..
I've finally finished my website - now's the time to do the tedious thing and get a decent hosting for as little money as possible.
Does anyone know a hosting that has:
- High privacy ethics (not that I'm gonna store porn there, just my screenshots posted via ShareX)
- VPS-based hosting I can put a nice Linux on.
- Unlimited or 'really high' bandwidth.
- Located in Europe (UK included lol).
I would be most thankful :P24 -
I switched my job a few months ago.
And now instead of having daily rants in our team lead's channel on slack on how I wish to inflict physical harm on one of my interns (and I'm talking interns that would just interrupt a daily to make their breakfast), and having something to bitch about because our method of version control was using the IDE's history.
And that I came on here to make another post about the times that I brought up that we should address our technical debt, and only being met with "we don't have technical debt" by our CTO.
I now have a good dev environment, with also a lot more trust given to the employees, where I actually don't have much to complain, and 0 reason to really post rants about my work here :D

Maybe I'm severely misunderstanding set theory. Hear me out though.
Let f equal the set of all fibonacci numbers, and p equal the set of all primes.
If the density of primes is a function of the number of *multiples* of all primes under n,
then the *number of primes* or density should shrink as n increases, at an ever increasing rate
greater than the density of the number of fibonacci numbers below n.
That means as n grows, the relative density of f to p should grow as well.
At sufficiently large n, the density of p is zero (prime number theorem), not just absolutely, but relative to f as well. The density of f is therefore an upper limit of the density of p.
And the density of p given some sufficiently large n, is therefore also a lower limit on the density of f.
And that therefore the density of p must also be the upper limit on the density of the subset of primes that are Fibonacci numbers.
WHICH MEANS at sufficiently large values of n, there are either NO Fibonacci primes (the functions diverge), and therefore the set of Fibonacci primes is *finite*, OR the density of primes given n in the prime number theorem
*never* truly reaches zero, meaning the primes are in fact infinite.
Proving the Fibonacci primes are infinite, therefore would prove that the prime number line ends (fat chance). While proving the primes are infinite, proves the Fibonacci primes are finite in quantity.
And because the number of primes has been proven time and again to be infinite, as far back as 300BC,the Fibonacci primes MUST be finite.

Managed to derive an inverse to karatsuba's multiplication method, converting it into a factorization technique.
Offers a really elegant reason for why non-trivial semiprimes (square free products) are square free.
For a demonstration of karatsubas method, check out:
https://getpocket.com/explore/item/...
Now for the reverse, like I said something elegant emerges.
So we can start by taking the largest digit in our product. Lets say our product is 697.
We find all the digits that produce 6 when summed, along with their order.
thats (1,5), (5,1), (2,4), (4,2), and (3,3)
That means for one of our factors, its largest digit can ONLY be 1, 5, 2, 4, or 3.
Lets take karatsubas method at step f (in the link) and reverse it. Instead of subtracting, we're adding.
If we assume (3,3)
Then we take our middle digit of our product p, in this case the middle digit of 697. is 9, and we munge it with 3.
Then we add our remaining 3, and our remaining unit digit, to get 3+39+7 = 49.
Now, because karatsuba's method ONLY deals with multiplication in single digits, we only need to consider *at most* two digit products.
And interestingly, the only factors of 49 are 7.
49 is a square!
And the only sums that produce 7, are (2,5), (5,2), (3,4), and (4,3)
These would be the possible digits of the factors of 697 if we initially chose (3,3) as our starting point for calculating karatsubas inverse f step.
But you see, 25 can't be a factor of p=697, because 25 is a square, and ends in a 5, so its clearly not prime. 52 can't be either because it ends in 2, likewise 34 ending in 4.
Only 43 could be our possible factor of p.
And we *only* get one factor because our starting point has two of the same digit. Which would mean p would have to equal 43 (a prime) or 1. And because p DOESNT (it equals 697), we can therefore say (3,3) is the wrong starting point, as are ALL starting points that share only one digit, or end in a square.
Ergo we can say the products of non-squares, are specifically non-prime precisely because if they *were* prime, their only factors would HAVE to be themselves, and 1.
For an even BETTER explanation go try karatsuba's method with any prime as the first factor, and 1 as the second factor (just multiply the tens column by zero). And you can see why the inverse, where you might try a starting point that has two matching digits (like 3,3), would obviously fail, because the values it produces could only have two factors; some prime thats not our product, or the value one, which is also not our product.
It's elegant almost to the level of a tautology. -
The first fruits of almost five years of labor:
7.8% of semiprimes give the magnitude of their lowest prime factor via the following equation:
((p/(((((p/(10**(Mag(p)-1))).sqrt())-x) + x)*w))/10)
I've also learned, given exponents of some variables, to relate other variables to them on a curve to better sense make of the larger algebraic structure. This has mostly been stumbling in the dark but after a while it has become easier to translate these into methods that allow plugging in one known variable to derive an unknown in a series of products.
For example I have a series of variables d4a, d4u, d4z, d4omega, etc, and these are translateable now, through insights that become various methods, into other types of (non-d4) series. What these variables actually represent is less relevant, only that it is possible to translate between them.
I've been doing some initial learning about neural nets (implementation, rather than theoretics as I normally read about). I'm thinking what I might do is build a GPT style sequence generator, and train it on the 'unknowns' from semiprime products with known factors.
The whole point of the project is that a bunch of internal variables can easily be derived, (d4a, c/d4, u*v) from a product, its root, and its mantissa, that relate to *unknown* variables--unknown variables such as u, v, c, and d4, that if known directly give a constant time answer to the factors of the original product.
I think theres sufficient data at this point to train such a machine, I just don't think I'm up to it yet because I'm lacking in the calculus department.
2000+ variables that are derivable from a product, without knowing its factors, which are themselves products of unknown variables derived from the internal algebraic relations of a product--this ought to be enough of an attack surface to do something with.
I'm willing to collaborate with someone familiar with recurrent neural nets and get them up to speed through telegram/element/discord if they're willing to do the setup and training for a neural net of this sort, one that can tease out hidden relationships and map known variables to the unknown set for a given product.17 -
Happened a few ago when I started taking SQL classes in school. We had our theory exam with one question asking us to display the date of the following day.

After a lot of work, the new factorization algorithm has a search space thats the factorial of (log(log(n))**2) from what it looks like.
But thats outerloop type stuff. Subgraph search (inner loop) doesn't appear to need to do any factor testing above about 97, so its all trivial factors for sequence analysis, but I haven't explored the parameter space for improvements.
It converts finding the factors of a semiprime into a sequence search on a modulus related to
OIS sequence A143975 a(n) = floor(n*(n+3)/3)
and returns a number m such that n=pq, m%p == 0||(p*i), but m%q != 0||(q*k)
where i and k are respective multiples of p and q.
This is similar in principal to earlier work where I discovered that if i = p/2, where n=p*q then
r = (abs(((((n)-(9**i)-9)+1))-((((9**i)-(n)-9)-2)))-n+1+1)
yielding a new number r that shared p as a factor with n, but is coprime with n for q, meaning you now had a third number that you could use, sharing only one non-trivial factor with n, that you could use to triangulate or suss out the factors of n.
The problem with that variation on modular exponentiation, as @hitko discovered,
was that if q was greater than about 3^p, the abs in the formula messes the whole thing up. He wrote an improvement but I didn't undertsand his code enough to use it at the time. The other thing was that you had to know p/2 beforehand to find r and I never did find a way to get at r without p/2
This doesn't have that problem, though I won't play stupid and pretend not to know that a search space of (log(log(n))**2)! isn't an enormous improvement over state of the art,
unless I'm misunderstanding.
I haven't posted the full details here, or sequence generation code, but when I'm more confident in what my eyes are seeing, and I've tested thoroughly to understand what I'm looking at, I'll post some code.
hitko's post I mentioned earlier is in this thread here:

Me at interview ->
Imagine the frustration you may go writing code in a different platform not having your vimrc. Than imagine the suicidal thoughts you have after you finish your program and have tabs mixed with spaces and indent errors, well on top of that imagine losing all the code highlighting all the code using X to yank it and P to paste in another file
Well, i shut down the vim session and lost all the code i wrote in 2 hrs3 -

I've been away a while, mostly working 60-70 hour weeks.
Found a managers job and the illusion of low-level stability.
Also been exploring elliptic curve cryptography and other fun stuff, like this fun equation...
i = log(n, 2**0.5)
base = (((int((n/(n*(1-(n/((((abs(int(n+(n/(1/((n/(n-i))+(i+1)))))+i)-(i*2))/1))/1/i)))))*i)-i)+i))
...as it relates to A143975 a(n) = floor(n*(n+3)/3)
Most semiprimes n=pq, where p<q, appear to have values k in the sequence, where k is such that n+m mod k equals either p||q or a multiple thereof.
Tested successfully up to 49 bits and counting. Mostly haven't gone further because of work.
Theres a little more math involved, and I've (probably incorrectly) explained the last bit but the gist is the factorization doesn't turn up anything, *however* trial lookups on the sequence and then finding a related mod yields k instead, which can be used to trivially find p and q.
It has some relations to calculating on an elliptic curve but thats mostly over my head, and would probably bore people to sleep.2 -

I'm having a hard time in choosing whether I should buy 2015 one or the 2016 one. Is not having enough ports really such a big issue?
Also, is there going to be a new MacBook Pro launch at the WWDC? :p5 -

In my team, I am not allowed to use ANY comments except for the really lengthy classes in the backend.
Thus, the code of the whole project (a complex webapp, consisting of 20-something Django projects and various services) is basically undocumented.
The slogan sounds "good code doesn't need commenting".
Seriously, fuck this and all of the times I scratched my head wondering "what the fuck is this spaghetti about".
Have any of you encountered something like this? Usually people don't want to comment, I would do it gladly but can't even make a small inline about what complex method is exactly doing :P3 -

Mac text substitution is coming to Chrome 77!
https://bugs.chromium.org/p/...
...and it's a TERRIBLE BLOODY IDEA. Any Chrome Mac users visiting any sites that display code will likely be shown the substituted crap, unless they've picked up on it and modified their site in time.
Seriously, take these cutsie "oohhhh, I want my ellipsis to display as a *proper* ellipsis character" mindsets and shove them where the sun don't shine. By all means provide the functionality as opt-in via a CSS declaration or whatever, but don't just assume your love of bloody "smart quotes" trumps everyone else's ability to see the *actual content* on the site.

Last year, I made an application of A* maze-solving algorithm in class. I used a linked list and my friends used arrays. Their algorithms were way faster than mine (I remade it later :p).
OK I understand that accessing memory by address if way faster than accessing by iterations, but I also see that python lists or C# lists are really fast. How is it possible to make a list performance-proof like this? Do the python interpreter make a realloc each time you append or pop a value?1 -
How the fuck do Jr devs end up doing things someone specifically asks not to do.!!!!!
Fucks timelines up
So I asked my Jr Dev to leave a feature as it might not be required in this release and rather concentrate on the thing that is gonna make this release work , the “SAVE” button.
I mean how had is it to understand,
This dude goes ahead and “utilises” days on the thing that isn’t gonna be released(a dropdown) , and no, the dropdown still doesn’t work.
I understand the spirit of solving the bugs first. But what’s the point of solving it if it doesn’t fucking “save”
P.S. I’ve done this too as a Jr Dev :p7 -
Hey guys...
Ever visited https://www.instructables.com ??
DMNNNN I just can't leave... So many cool Ideas...
I don't have anything to do with the site, found it yesterday while searching for arduino stuff, and MANNNN .... It has the best pratical tutorials I ever saw... Not like most, where they teach you the basics...
Most sites, first arduino APP, light a Led
Instructables, First App, Instructions with pictures and videos on how do connect the Arduino, install IDE (this is the most basic tutorial after all). then the tutorial, Light 4 leds and do a lightshow...

Maybe the twitter developers getting laid off should join spotify in their quest for a simple shuffle algorithm that they failed to develop or maybe just are not allowed to ship due to corrupt company politics?
As Spotify's algorithm sucks from a listener's perspective (major music industry might like it though), I have to rely 100% on curated playlists, and without shuffle, I have to listen in the exact order that they were made. Why not? We did the same when we put actual records on a record player. Who needs shuffle? Who needs streaming anyway? I'm gonna get a pair of turntables or just listen to MP3 files again!
There is a "new idea" thread in the spotify community forum started in 2020 (following up on an earlier 2012 suggestion), a feature request for the "option to have a true shuffle" that already has 70+ pages, tagged as trending in 2021 with the friendly stalling message:
As this idea has gathered a fair amount of votes, we've discussed it with the relevant team once again. We actually want to take a closer look at what you're experiencing and get some of you in touch with our devs.
Good luck everyone. If I still use Spotify in 2023, I can probably repost the very same status again one year later when the app will still lack a simple shuffle option, no?

This is it, today I am getting one of my wisdom teeth removed. Wish me luck! Also, if I’m talking here, I just wanna say: I am officially moving away from SwiftUI and switching to UIKit. I’ve been constantly building my way around SwiftUI, constantly bypassing SwiftUI and adding UIKit layers around it. It has been such a headache using SwiftUI to construct such complicated views and I figured that the pace of development has been rapidly declining due to SwiftUI. I am going to rewrite the whole app again but in UIKit (it’s still native).

This error, which took me a long time to find, demonstrates the importance of useful variable names.
Using the Wolfram Language:
pp = {};
For[i = 0, i <= Max[p], i++, If[Count[p, i] != 0, pp = Join[pp, {{i, Count[pp, i]}}], -1]];
pp

<!doctype confusedRant 😕>
Plot: we need to release our website in two weeks which holds at least a thousand pages. All these pages are manually migrated from the old website, which doesn't have a database. Current status: 650 pages/1000 are completed, 40 different templates need to be adapted. I'm alone on these templates, my colleagues create the pages and fill the new database
So I'm working on the templates a WebDev coded for our website on a licensed CMS, and had this decently simple html block that looks like a square and consisting of roughly this (Emmet style):
a.area > blockquote > strong.title + p
After adding another <a> element inside the p, I noticed that my <a> wouldn't display and bust the whole look of the square.
Just for more details, the CSS the dev made is ultra specified (meaning each element is too precisely "described" : div.class .child .child2 { /* styles */ } when it could be .class .child2 for example). Also, the templates he made need to be compatible with any "module" the website has, thus the need of this high specificity
So I fired up the DevTools to check what happened, and had:
Expected: a.area > blockquote > strong.title + p > a
Actual result: some new a.area were wrapping the <strong>, the <p> and the <a> I just added. The source code was not showing any of this but just the rules I initially wrote - the expected result
Wtf?! I thought the JS the dev made was adding elements. I disabled said JS, and bam, these a.area were still wrapping everything!! What black magic would add these stupid tags I never asked for.
So I went looking in the CSS files in case some wizardry was happening, but everything was OK.
I tried changing my structure, changing tag (swapping a.area to p.area or without .area), HTML just said "nope, have those please".
Eventually I rewrote my own module out of frustration after three quarters of an hour fiddling with this stupid "module". I hate losing time for such shenanigans and under a lot of pressure because of deadlines.
Still haven't figured why those <element>.area would wrap everything out of nowhere...3 -

Oh god, structure alignement, why you do this... You might be interested if you do C/C++ but haven't tried passing structures as binary to other programs.
Just started working recently with a lib that's only a DLL and a header file that doesn't compile. So using python I was able to use the DLL and redefined all of the structures using ctypes, and the nice thing is: it works.
But I spent the whole afternoon debugging why the data in my structures was incoherent. After much cussing, I figured out that the DLL was compiled with 2 bytes packing...
Packing refers to how structures don't just have all the data placed next to each other in a buffer. Instead, the standard way a compiler will allocate memory for a structure is to ensure that for each field of the structure, the offset between the pointer to the structure and the one to the field in that structure is a multiple of either the size of the field, or the size of the processor's words. That means that typically, you'll find that in a structure containing a char and a long, allocated at pointer p, the double will be starting at p+4 instead of the p+1 you might assume.
With most compilers, on most architectures, you still have the option to force an other alignment for your structures. Well that was the case here, with a single pragma hidden in a sea of ifdefs... Man that took some time to debug...2 -

Before I left my other company I was in the midst of finishing one project and I was ansious to finish everything to leave as a rockstar. Now, one of my js scripts brought a huge and long json response that had many nested items and arrays and whatnot. Instead of properly destructuring or finding a particular piece that went similarly to "status": "Verify input"(that was nested unser a shitload of items) i did the unspeakable......i stringified the whole object and just used indexOf.
I still feel guilty over it...but it works :P thing is, if it returns that it means that the user entered an invalid status into the app (it was an inventory application) but it works :P
Oh well. Mind you they thought it was going to take months and I finished in 1 week so yay. -

I was about to print a bigass document. Wanted to save paper, and saw my printer had a two side mode. I try it out. A few pages print, then the driver says PAUSED - RELOAD PAPER. This is normal, as double sided printing is not automatic. Underneath, there is a message:
[Printing - Manual Duplex: Please reinsert pap...]
I try to resize the window to read the message.
THE MOTHERFUCKING WINDOW WAS NOT RESIZEABLE!!!
are these products not fucking tested???
I find a guide saying the paper should be reinserted with no flips, then the "continue" button should be pressed.
The button was not in the driver UI, or on the printer. Further research showed that you are supposed to:
OPEN THE TONER CHANGE DOOR AND CLOSE IT AGAIN TO CONTINUE A PRINT

IT: just put them inside the folder that has the files of the main site, it doesn't matter.
P: we have some sub-domains that we do not use anymore, what do we do with them?
IT: just delete the files, don't bother with deleting the subdomain
P: we are having an event, what do we use to store user applications, we used google forms previously and it worked just fine.
IT: we will have the applications go to our mySQL database, but everything will be in one table so that it's more readable.

Looking for someone to test a new factorization script I wrote.
https://pastebin.com/Td2XTKe6
Tested against a set of products from all primes under 1000. Worked even on numbers up to 87954921289
Worked for about 66% of the products tested.
Obviously I'm cheating a little bit because I'm checking for four conditions n%a == 0, n%a == 1, n%b == 0, and n%b == 1
It appears it is possible to generate the series from just the product, and then factor each result. The last factor in each each set of factors becomes x, and we do p%x and check for zero.
if it works, we've found our answer.
Kind of wonky but basically what its doing is taking p, tacking on a 0 to the right, and then tacking p to the right of *that*.
So if you had a product like
314
The starting number we look at is
3140314
The middle digit becomes i, and the unit digit becomes j.
Don't know why it works more often then not, and don't know if it would really be any faster.
Just think it's cool.9 -

And I needed to use str_replace in a string to cancel out some values.

Later, I used $p[1] for further processing. -

Wherein I disprove Goldbachs Conjecture (in one specific case)
golbach conjecture:
every even number is the sum of two primes
lets call the primes p and q
lets call our even number p+q=n
we can go further by establishing two additional variables
u=p-1, v=q-1
therefore every even number is the sum of u+v+2, according to goldbach's own reasoning.
in the simplest case...
p=2, q=2, p+q=4
u=1, v=1, u+v+2 = 4
We can therefore make a further conjecture in the simplest case every sum of two primes, less 2, is the sum of two composites. This likely has connections to the abc conjecture for a variety of reasons. But leaving ancillary discussion aside for a moment...
We can generalize to a statement that every even number is the sum of two odd numbers. And every odd number greater than 1 is the sum of an odd number and an even number.
Finding an even number that is not the sum of (p-1)+(q-1) would therefore be equivalent to disproving the goldbach conjecture. Likewise proving every even number is the sum of (p-1)+(q-1) would be the equivalent of proving it.
Proving all even numbers greater than 2 are the sum of two composites + 2 would be proof of goldbachs conjecture, and finding any example or an equation that proves an example exists such that *some* subset of even numbers are NOT the sum of two composites +2, would disprove the conjecture.
Lets start with a simple example:
2+2=4
because 4-2=2, and two is not the sum of two composite numbers goldbachs conjecture must ipso facto be false.

Math question time!
Okay so I had this idea and I'm looking for anyone who has a better grasp of math than me.
What if instead of searching for prime factors we searched for a number above p?
One with a certain special property. BEAR WITH ME. I know I make these posts a lot and I'm a bit of a shitposter, but I'm being genuine here.
Take this cherry picked number, 697 for example.
It's factors are 17, and 41. It's trivial but just for demonstration.
If we represented it's factors as a bit string, where each bit represents the index that factor occurs at in a list of primes, it looks like this
1000001000000
When converted back to an integer that number becomes 4160, which we will call f.
And if we do 4160/(2**n) until the result returns
a fractional component, then N in this case will be 7.
And 7 is the index of our lowest factor 17 (lets call it A, and our highest factor we'll call B) in our primes list.
So the problem is changed from finding a factorization of p, to finding an algorithm that allows you to convert p into f. Once you have f it's a matter of converting it to binary, looking up the indexes of all bits set to 1, and finding the values of those indexes in the list of primes.
I'm working on doing that and if anyone has any insights I'm all ears.9 -

Igor Girkin (Strelkov) is a putin’s militant. He’s one of the reasons behind the war in Donbas.
The funny thing is, some time ago he was imprisoned by russia for some reason. Yes, putin basically makes his bitch invincible but later imprisons him. AND while detaining him, his fake passport was found. The name there was Sergei Runov, S. Runov for short.
In russian, it basically means something like “Pooperson”, a bit like Chris Paul Bacon shortened to Chris P. Bacon means “crispy bacon”.
He could’ve chosen any name for his fake passport, any name at all. But he chose this.

Background download, lockscreen and wallpaper all use different methods, trying to see which one works better, doesn't use a separate background process by itself hence easier on the system resources.
the "dismiss" is there just so the notifs carry images in phone. Somehow, notifs with just images and no buttons didn't show the images on phone, hence a temporary workaround, will be replaced with actual buttons later :p
Search and sketch don't work the way I want em to, are there but not accessible, will be there eventually.
tips? things I should change? anything?

!Rant but a question :)
So, I'm in college learning software engineering and kind of don't see the point of try-harding. I have always been very good at learning so I only started studying late high-school because grades were important for collage entrance. But now that I'm here and my grades have all been very good (15/20 in the worst cases), I'm not motivated to go the mile further, specially because I don't have friends to compete with (or enemies for that matter :P).

So my teacher's website was made by him and run on go Daddy, he taught precalculus, calculus, algebra, algebra ii, and computer science.

His directory that had the tests, test answers, exams, exam answers, and homework answer's as well as all the books he's written in PDFs, was unprotected, I could access and download them all. He also had a database directory that contained all the students' phone numbers, email addresses, home addresses, and their full names.

P: Okay, and why is your code commented?
F: Because it's good practice and we learned in subject x last semester.
P: Impossible! I teach that subject and I did not teach that in my classes.
F: Okay, but our professor did.
P: *Says nothing*.
They got a 3.25/5 as a grade for it and got really pissed off. I mean, they spent a lot of time making the assignment's structure perfect, optimizing their code and the professor did not care for the structure, just the methods, on the data structures subject.
FYI, they are workaholic, dedicate a lot of time improving their skills and their normal grades are usually >= 4.25.2 -
Goddamnit, I've been rumaging around a CMS -generated site (not wordpress) for a friend in devtools.(to suggest improvements) I don't have much experience with CMS, but why is there so much fucking useless nested markup everywhere that has to go down the line. A simple paragraph has at least 6x nesting, a nav is "centered" by having a millionenty billionety divs on each side, there was even a span element for a single character inside a <p>.
What a fucking mess.5 -
Is there a common style name/popular origin for the style of whitespace in code where you put spaces inside parentheses but not after keywords in control statements, or after function names? (See img)
This is my preferred whitespace method (in most languages), but I don't know where I adopted it from, if anywhere... ;P16 -

The factorization shit I'm always ranting about? I decided for once to explain it visually in this handy dandy little infographic.
We're essentially transforming the product from an unsmooth set of potential factors in its factor tree, to a factorization tree that guarantees first that the set of potential factors are all 2, 3, 5, and a or b of p, and second, that all the factors are *smooth integers* of a or b.
This is basically what Adi Shamir was trying to do with TWINKLE and TWIRL, despite checking a hundred thousand+ potential primes.
I did it in four.7 -
So I made a couple slight modifications to the formula in the previous post and got some pretty cool results.
The original post is here:
https://devrant.com/rants/5632235/...
The default transformation from p, to the new product (call it p2) leads to *very* large products (even for products of the first 100 primes).
Take for example
a = 6229, b = 10477, p = a*b = 65261233
While the new product the formula generates, has a factor tree that contains our factor (a), the product is huge.
How huge?
6489397687944607231601420206388875594346703505936926682969449167115933666916914363806993605...
and
So huge I put the whole number in a pastebin here:
https://pastebin.com/1bC5kqGH
Now, that number DOES contain our example factor 6229. I demonstrated that in the prior post.
But first, it's huge, 2972 digits long, and second, many of its factors are huge too.
Right from the get go I had hunch, and did (p2 mod p) and the result was surprisingly small, much closer to the original product. Then just to see what happens I subtracted this result from the original product.
The modification looks like this:
(p-(((abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1)-p)%p))
The result is '49856916'
Thats within the ballpark of our original product.
And then I factored it.
1, 2, 3, 4, 6, 12, 23, 29, 46, 58, 69, 87, 92, 116, 138, 174, 276, 348, 667, 1334, 2001, 2668, 4002, 6229, 8004, 12458, 18687, 24916, 37374, 74748, 143267, 180641, 286534, 361282, 429801, 541923, 573068, 722564, 859602, 1083846, 1719204, 2167692, 4154743, 8309486, 12464229, 16618972, 24928458, 49856916
Well damn. It's not a-smooth or b-smooth (where 'smoothness' is defined as 'all factors are beneath some number n')
but this is far more approachable than just factoring the original product.
It still requires a value of i equal to
i = floor(a/2)
But the results are actually factorable now if this works for other products.
I rewrote the script and tested on a couple million products and added decimal support, and I'm happy to report it works.
Script is posted here if you want to test it yourself:
https://pastebin.com/RNu1iiQ8
What I'll do next is probably add some basic factorization of trivial primes
(say the first 100), and then figure out the average number of factors in each derived product.
I'm also still working on getting to values of i < a/2, but only having sporadic success.
It also means *very* large numbers (either a subset of them or universally) with *lots* of factors may be reducible to unique products with just two non-trivial factors, but thats a big question mark for now.

Some magic happened about situation talked in earlier rant at below link.

Now magically even before I inform about this situation directly to the client, now after 8 years they used some proprietary static code analyzer on latest app source & found out around 200+ security issues which covers most pain points I told in the above rant.
I also found out that there is a list of 100+ vulnerabilities documented in client doc repo, which were pending since around 5-6 years.
Now I have to work along my junior to fix these both kind of issues.

Heres the initial upgraded number fingerprinter I talked about in the past and some results and an explanation below.

Hastebin wouldn't save for some reason so paste.ofcode.org it is.
Not much to look at, but I was thinking I'd maybe mark the columns where gaps occur and do some statistical tests like finding the stds of the gaps, density, etc. The type test I wrote categorizes products into 11 different types, based on the value of a subset of variables taken from a vector of a couple hundred variables but I didn't want to include all that mess of code. And I was thinking of maybe running this fingerprinter on a per type basis, set to repeat, and looking for matching indexs (pixels) to see what products have in common per type.
Or maybe using them to train a classifier of some sort.
Each fingerprint of a product shares something like 16-20% of indexes with it's factors, so I'm thinking thats an avenue to explore.
What the fingerprinter does is better explained by the subfunction findAb.
The code contains a comment explaining this, but basically the function destructures a number into a series of division and subtractions, and makes a note of how many divisions in a 'run'.
Typically this is for numbers divisible by 2.
So a number like 35 might look like this, when done
p = 35
((((p-1)/2)-1)/2/2/2/2)-1
And we'd represent that as
ab(w, x, y, z)
Where w is the starting value 35 in this case,
x is the number to divide by at each step, y is the adjustment (how much to subtract by when we encounter a number not divisible by x), and z is a string or vector of our results
which looks something like
ab(35, 2, 1, [1, 4])
Why [1,4]
because we were only able to divide by 2 once, before having to subtract 1, and repeat the process. And then we had a run of 4 divisions.
And for the fingerprinter, we do this for each prime under our number p, the list returned becoming another row in our fingerprint. And then that gets converted into an image.
And again, what I find interesting is that
unknown factors of products appear to share many of these same indexes.
What I might do is for, each individual run of Ab, I might have some sort of indicator for when *another* factor is present in the current factor list for each index. So I might ask, at the given step, is the current result (derived from p), divisible by 2 *and* say, 3? If so, mark it.
And then when I run this through the fingerprinter itself, all those pixels might get marked by a different color, say, make them blue, or vary their intensity based on the number of factors present, I don't know. Whatever helps the untrained eye to pick up on leads, clues, and patterns.
If it doesn't make sense, take another look at the example:
((((p-1)/2)-1)/2/2/2/2)-1
This is semi-unique to each product. After the fact, you can remove the variable itself, and keep just the structure in question, replacing the first variable with some other number, and you get to see what pops out the otherside.
If it helps, you can think of the structure surrounding our variable p as the 'electron shell', the '-1's as bandgaps, and the runs of '2's as orbitals, with the variable at the center acting as the 'nucleus', with the factors of that nucleus acting as the protons and neutrons, or nougaty center lol.
Anyway I just wanted to share todays flavor of insanity on the off chance someone might enjoy reading it.1 -

"I claim that the trend which AI/ML continues for lawyers is one that it starts for programmers. Just like how a partner at Cravath likely sketches an outline of how they want to approach a particular case and swarms of largely replaceable lawyers fill in the details, we are perhaps converging to a future where a FAANG L7 can just sketch out architectural details and the programmer equivalent of paralegals will simply query the latest LLM and clean up the output. Note that querying LLMs and making the outputted code conform to specifications is probably a lot easier than writing the code yourself ー and other LLMs can also help you fix up the code and integrate the different modules together!"1 -

So recently I've been feeling like I fooled myself into thinking I'm any good at anything regarding development.
Today I tried to deploy a Console Application that would run nightly. The production systems are much more guarded, as it should be, but I should still be able to schedule a windows task (yeah yeah, windows servers, not the time Linux fanboys and not my choice :P) no problem.
Except I didn't expect that network users can't run jobs, because of a Group Policy about saving passwords on network accounts.
I expected a local administrator account to be available, and it wasn't.
Also a web API isn't available, even though I could telnet to the address on port 443 (HTTPS). A proxy apparently accepts all HTTP/HTTPS traffic and so on.
All this I feel like I should have known....
So am I in my own head, or am I right in thinking maybe I'm not "pro" development yet? Maybe I don't deserve to be "pro".
Thoughts?4 -
Heres a fairly useless but interesting tidbit:
if i = n
then
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
then r%a will (almost*) always return 0. when n = floor(a/2) for the lowest non-trivial factor of a two factor product.
Thats not really the interesting bit though. The interesting bit is the result of r will always be some product with a *larger* factor tree that includes the factor A of p, but not p's other larger factor, B.
So, useless from what I can see. But its an interesting function on its own, simply because of what it does.
I wrote a script to test it. For all two-factor products of the first 1000 primes, (with no repeating combinations, so if we calculated say, 23*31, we skip 31*23), only 3262 products failed this little formula, out of half a million.
All others reliably returned 0 for the following..
~~~
i = floor(a/2)
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
r%a
~~~
The distribution of failures was *very* early on in the set of factors, and once fixed at the value of 3262, stopped increasing for the rest of the run.
I didn't calculate if some primes were more likely to cause a product to fail or not. Nor the factor trees, nor if the factor trees had any factors in common between products, or anything of that nature.
All in all I count this as a worthwhile experiment.
If you want to run the code yourself, I posted it to pastebin here:

Let some number P be the product of two factors, A and B
Let the iterations of A*1..2..3..N up to B+1 be a directed graph.
Would this graph be eularian?
If so then it should be possible to use the BEST algorithm to count the number of eularian circuits, yielding B, no?
Edit: this is supported by the following text:
An arborescence can equivalently be defined as a rooted digraph in which the path from the root to any other vertex is unique.
* * *
Where the product of any two primes is unique, the path to it across our graph here, is also unique. -

Hang with me! This is *not* a math shitpost, I repeat, it is NOT a math shitpost, not entirely anyway.
It appears there is for products of two non-trivial factors, a real number n (well a rational number anyway) such that p/n = i (some number in the set of integers), whos factor chain is apparently no greater than floor(log(log(p))**2)-2, and whos largest factor is never greater than p^(1/4).
And that this number is at least derivable, laboriously with the following:
where p=a*b
https://pastebin.com/Z4thebha
And assuming you have the factors of p/z = jkl..
then instead of doing
p/(jkl..) = z
you can do
p-(jkl) to get the value of [result] whos index is a-1
Getting the actual factor tree of p/z is another matter, but its a start.
Edit: you have to provide your own product.

This is a question and a rant
I have to get temperature readings from an andriod app written in ionic angular to a webpage written apache wicket... No, I don't have any control over either stack.
The kicker is the wicket app isn't even run properly attached to a domain, it's just run from a box at the client and then the client machines connect through <server ip>:8080/appname
Which means I can't solve my problem by simply having the website and app on the same domain and then use local storage...
I have tried
Ionic
window.postMessage({ type: 'temperatureData', data: tempFormatted }, '*');
Test it from this page
<!-- index.html (web page) -->
<!DOCTYPE html>

if (event.data.type === 'temperatureData') {
// Update the temperature data on the page
document.getElementById('temperatureData').textContent = event.data.data;
}
});

Having some issues with my laptop seizing up in graphical linux desktop environments, probably due to some peripheral power management. I saw there was a bios setting for "make linux work" but I couldn't find mention of it in the manual (why is this usually so hard to find, anyway?), so I googled a bit before I messed with it.
https://forums.lenovo.com/t5/...
Worst case I guess I'd just reset the bios, but it always blows my mind seeing issues like these go seemingly unaddressed. That's a 12 page discussion from 2018 where you brick your laptop - a fairly high end one at that - by flipping a bool and the latest response is "Same issue here".
Is it just PR practice to not acknowledge these things or is it likely that they are legitimately unaware? Does it not get escalated properly or do they reckon there's not enough benefit to address it?
Whatever the case, my faith in Lenovo is certainly starting to show cracks. I used to see it as the "correct" laptop brand, but nowadays I'm equally iffy about all of them.3 -
Got a question on DBMS Normalization. I tried searching but couldn't clear my doubt. So I have a set of functional dependencies for relation R(C, D, E, F, P, R, S) :
F->D
D->F
E->C
P->RC
E->F
S->EFD
PR->EF
So I have to convert this to 3NF. My doubt is that when finding 2NF do we find all the non-prime attributes that are dependent on a particular partial key i.e. do we take it's closure and create new relations for each partial dependency? If we do that then there are overlapping attributes in the resultant relations in this case I found the relations in 2NF as :
R1(P, S)
R2(P, R, C, E, F)
R3(S, E, F, D, C)
But when I just used the FDs as they are given (no closure) I found :
R1(P, S)
R2(P, R, C)
R3(S, E, F, D)
Which one is correct, please help.3 -
If we can transform the search space or properties of a product into a graph problem
we could possibly use Kirchhoff's theorem to reveal products which are 'low complexity'
in particular search spaces, yeah?
Now according to
https://en.wikipedia.org/wiki/...
"n Cycle Space, A family of sets closed under the symmetric difference operation can be described algebraically as a vector space over the two-element finite field Z 2 {\displaystyle \mathbb {Z} _{2}} \mathbb{Z } _{2}.[4] This field has two elements, 0 and 1, and its addition and multiplication operations can be described as the familiar addition and multiplication of integers, taken modulo 2"
Wouldn't this relate to pollards algorithm, because it involves looking for factors of coprimes modulo N or am I mistaken?
Now, according to wikipedia, "in a group, the additive identity is the identity element of the group, is often denoted 0, and is unique."
If we make the multiplicative identity of our ring or field a tuple of the ratio of a/b for some product p, or a (and a/w, where w is the square root of p), or any other set such that n*m allows us to derive a or b, we could reduce the additive identity to the multiplicative identity, making the ring trivial. Solving for p would then mean finding a function from R to R, mapping every number to 0, i.e. finding the additive identity.
Now in a system with a multiplication operation the distributes over addition, the "additive
identity annihilates ring elements", so naturally, the function that maps to 0, gives us
our additive identity, we need only find the subset, no?
Forgive me if I'm wrong, but shouldn't this be convertible to a graph search?
I'm WAY out of my depth here so if anyone is familiar and can enlighten me I'd be grateful.

A friend outsourced a project to us with partial requirements. We developed it as per the requirements and submitted the app and admin portal to his client.

Generally we provide an admin portal to manage the backend of the app, but in this project a backend was to be made but the adding or modifying users section was not mentioned in the requirement.

"Robot, let us pray! Can and should robots have religious functions? An ethical exploration of religious robots" by Anna Puzio.
"With approximately 20 religious robots worldwide, religious robotics is still in its early stages (Balle 2022). However, there are already some notable examples of religious robots, and with advancing technology, it is expected that their numbers will increase. Here is a brief overview: BlessU-2, a German robot, delivers blessings in various languages (Löffler et al. 2021, p. 575). SanTO (the Sanctified Theomorphic Operator) (Trovato et al. 2019) takes on the appearance of a Christian Catholic saint and recites sacred texts while accompanying the faithful in prayer. It also serves as a companion with psychological functions, contributing to the well-being of individuals, particularly the elderly (Löffler et al. 2021, p. 573; Trovato et al. 2021, p. 545). Celeste, resembling a Catholic angel, provides spiritual guidance through prayer and prints personalized Bible verses. Meanwhile, Mindar, a robot priest in Japan, embodies the Buddhist teacher, Kannon Bodhisattva, and conducts Zen ceremonies at the temple (Smith 2022, p. ch. 5; Klein 2019). The monk robot, Xi’aner, follows visitors around the temple, responds to their inquiries about Buddhism and plays Buddhist music. It is also available as a chatbot with which you can communicate over online messenger services. Xi’aner is designed with the purpose of promoting Buddhism in China (Trovato et al. 2021, p. 544; Löffler et al. 2021, p. 573). Consequently, it is perceived not as a threat to religious teachings but rather as a means of contributing to the dissemination of Buddhism (Löffler et al. 2021, p. 573). Moreover, in Japan, the humanoid robot Pepper is utilized in Buddhist funerals because it is cheaper than a human priest. It also broadcasts the ceremony over the internet for those who are unable to attend (ibid.). Michael Arnold et al. (2021) delve into the deployment of Carl, Pepper, and the robot dog, Aibo, in funeral settings."

THIS is powering the internet:
"[...] was a protocol number, similar to the third argument to socket today. Specifying this structure was the only way to specify the protocol family. Therefore, in this early system the PF_ values were used as structure tags to specify the protocol family in the sockproto structure, and the AF values were used as structure tags to specify the address family in the socket address structures. The sockproto structure is still in 44BSD (pp. 626-627 of TCPv2) but is only used internally by the kernel. The original definition had the comment "protocol family" for the sp_family member, but this has been changed to "address family" in the 4.4BSD source code. To confuse this difference between the AF_ and PF_ constants even more, the Berkeley kernel data structure that contains the value that is compared to the first argument to socket (the dom family member of the domain structure, p. 187 of TCPv2) has the comment that it contains an AF_ value. But some of the domain structures within the kernel are initialized to the corresponding AF value (p. 192 of TCPv2) while others are initialized to the PF value."

So I finally got something to allow me to pipe my network over ssh when I need it.
alias mcserversshproxy='ssh -p <port> -N -D localhost:9999 <user@server>'
I can now use the internal webpage in my network by configuring a profile in firefox as a proxy. Kind of slick!
This tutorial, despite its flaws, helped me work this out:

text-size-adjust vs viewport meta tag
So, I'm designing a mobile-first website with the chrome mobile simulator. I saw that when I put some text in it, for example a <p>, it will display very very small, and will not take into consideration the font size that I gave it, unless the <p> contains several lines of text. I did some research and I figured that this behavior is due to the text inflation algorithm used by mobile browsers and it can be stopped by using text-size-adjust:none. Is that correct? Then, the viewport meta tag. I figured that the viewport meta tag is used when a website it is not designed mobile first, and will help display the content properly based on the smaller width of a mobile devide. Is that correct? In conclusion, text-size-adjust with the value of none is used when building a mobile-first website in order to stop that inflation algorithm and help display the text properly, and the viewport meta tag is used when bulding a NON mobile-first website. Is that correct? Thank you6 -
<p>Do you know how clean tap water is? The answer to that question largely depends on where you live, but thinking about it is always a good idea. Drinking water is often contaminated with organic compounds, minerals, chlorine, and chemicals left over from the water treatment process. If you need cleaner water, the easiest way to do this is to get a filtered jug. This guide of <a href="https://womenselections.com/best-wa...">what is the best water filter pitcher</a> will help you find the best water filter jug for your needs and budget.</p>
<p>Filtered launchers are very diverse. To help the reader, we limit ourselves to a few outbreaks through testing and research. We tested various models ourselves, we examined a large number of launcher classifications and confirmed our own findings.</p>
<p><a href="https://ibb.co/19CRS7S"><img src="https://i.ibb.co/55Qs7G7/..." alt="best-water-filter-pitcher" border="0" /></a></p>
<p><strong>Water filter pitcher filter type</strong><br />The filter jug comes with various types of cartridges. Typically, only one type of cartridge can be used, so you cannot select the desired cartridge. The exception is if you select a brand that offers a choice between two cartridges. Each of these cases has its advantages.</p>
<p><strong>Carbon filtration</strong><br />Most cartridges use carbon and are particularly effective at filtering chlorine and its by-products, such as TTHM. These cartridges contain blocks of solid carbon or granular activated carbon (also called activated carbon). In both cases, carbon usually comes from coconut shells, but it can also be made from coal, brown coal, wood, or oil pitch. Carbon can be physically or chemically activated.</p>
<p>There are two ways to physically activate carbon. One is to heat the carbonized material to 450-900 degrees Celsius in an inert atmosphere. Usually nitrogen or argon is present. Alternatively, the manufacturer may use oxidation. In this case, the material is typically heated to 1200 degrees Celsius and exposed to oxygen.</p>
<p>Chemical activation involves the injection of various chemicals into the material. The most common chemicals are hydroxide, sodium hydroxide, zinc chloride, calcium chloride. These chemicals facilitate carbon activation. This means that the process takes less time. However, the material must be heated to 450-900 degrees Celsius.</p>
<p>As the water passes through the cartridge filter, the carbon absorbs liquid and gaseous impurities. Due to the highly porous surface and physical form of activated carbon, one gram has an absorbent surface of 32,000 square feet. Still, it becomes saturated with impurities. If this occurs, you will need to replace the cartridge.</p>
<p><strong>In the conclusion</strong><br />If you are considering buying a pitcher filter as the only filter in your home, you should know what your water contains before you buy it. Today, many launchers have successfully removed most of the harmful contaminants. On the other hand, there are still bottles that can only filter out basic contaminants. As always, I recommend that you test your water before purchasing a pitcher.</p>
<p>Whatever it is, healthy water should always be a priority. I hope my comments, suggestions and guidelines will help you buy the best <a href="https://arizonawet.arizona.edu/user...">water filter pitcher review</a>. However, if you don't think the launcher is a viable option and have considered all of the options, please feel free to visit our website. He uploaded many other honest reviews like this. I am sure you will find the best option.</p> -
Well, you share ideas with like-minded individuals, you work on what you like and you try to make the most out of it, and maybe get famous on the way (a small bonus). We progress the current technology to the edge using more efficient software. It’s basically answering a question: what is “peak performance” in the blend of hardware and software.
At least that’s how I feel about it.
:P6 -
see. anything they make that is good could pass for one of ours :P

Ok, there is one good thing. I've reached 333 +1's. Thank you all guys!
Sooo... a few days ago my Power supply from my home pc died. It was a good one, but I don't know.. it just burned nearly..
Today I've received a new one.
Plugged everything in. PC runs - or not?? WTF! Windows (yeah, at home still Windows ) isn't booting anymore. Hardware changes detected. I think, through the broken Power supply something got damaged.. shit.. and know what - don't have any Backup. Shit. At least some important data is on another hdd, which hopefully is fine. Now I'm trying to rescue the data with another hdd installing a fresh Windows.
Whish me luck!
PS: No, the power supply wasn't from Samsung, even when it exploded nearly :P1 -
I just never expected to run into people who don't have shit better to do then literally the same shit and cyberstalking people they don't even know trying to act like they give a damn for personal amusement or just lurking in the same places waiting to spring up and say the same thing or just whatever the hell this crap is when the person they're doing this too doesn't really have anything of interest other than precisely what i've indicated, that or try to be nosy and be amateur intelligence people trying to gather information over what a person is thinking regarding the activities of certain garbage in his environment :P emphasis on amateur.1

Got a Job lately and therefore three Interviews.
In two of them was a question about SQL Injektion and no matter what teck stack you apply for that's the time to mention PHP :P1 -
So I was remembering something today. And the ugliness of it makes it difficult to focus on constructive things.
Apparently one of the things they were doing during the vietnam war was buying the identifies of either dead, murdered, or awol soldiers to put people in their place who were running from the law, or were monsters in general trying to hide from things they did. how nice. the whole unit would claim it was the person. for what payout ? or was the unit just some of these people undiscovered ? always the question. but if things like this became common knowledge someone talked, which is likely why I was spared iraq.
dumped a whole bunch of trash there, as the war made no sense in the first place. :P -
Are dev's pussies everywhere now ?

Simple error.
He did what most people do and said 'oh this is already working. always was working, never would not work.'
add a fiddle indicating, 'no, whatever update was added for some reason most emphatically is NOT working'
get a 'code of conduct' suggestion, for mentioning the circular bs around and around in time when the original guy is probably dead.
betcha anything its not fixed :P
betcha he left the code in place :P
god its like overnight devs decided to be grumpy assholes in a sneaky way, like the faggot barry I described at one point, because they wilt when directly approached and emotion is added in besides their weird bug eyed, watery eyed, teary eyed, horrified because they're now all baby touchers, bullshit.18
