Do you ever feel coding fatigue?
My dev mana has run dry, I've hit my rate limit.
That moment where your brain thinks "I should finish building this React project, it's good for my portfolio" or "I should really work on fixing this query performance issue, I already know what the problem is" — but your stomach churns at the thought of having to interpret even a single line of code?
The last few days it really does feel like a physical illness, a nauseated feeling whenever I open an IDE. I have written about 12 lines of code since Monday.
It goes beyond writer's block, it's not a lack of focus or inspiration, it's a big knot in my head of everything that's wrong and inconsistent in development, and it causes feelings of dread, desperation and revulsion when trying to wrap my head around the simplest stuff.
Does anyone have good tips to overcome this feeling, something faster and less savings-account-destroying than "take a sabbatical year and travel the world riding an emu"? (seems tempting though)57 -
Ladies and gentlemen, prepare yourselves for a rant with a capital R, this is gonna be a long one.
Our story begins well over a year ago while I was still in university and things such as "professionalism" and "doing your job" are suggestions and not something you do to not get fired. We had multiple courses with large group projects that semester and the amount of reliable people I knew that weren't behind a year and in different courses was getting dangerously low. There were three of us who are friends (the other two henceforth known as Ms Reliable and the Enabler) and these projects were for five people minimum. The Enabler knew a couple of people who we could include, so we trusted her and we let them onto the multiple projects we had.
Oh boy, what a mistake that was. They were friends, a guy and a girl. The girl was a good dev, not someone I'd want to interact with out of work but she was fine, and a literal angel compared to the guy. Holy shit this guy. This guy, henceforth referred to as Mr DDTW, is a motherfucking embarrassment to devs everywhere. Lazy. Arrogant. Standards so low they're six feet under. Just to show you the sheer depth of this man's lack of fucks given, he would later reveal that he picked his thesis topic "because it's easy and I don't want to work too hard". I haven't even gotten into the meat of the rant yet and this dude is already raising my blood pressure.
I'll be focusing on one project in particular, a flying vehicle simulator, as this was the one that I was the most involved in and also the one where shit hit the fan hardest. It was a relatively simple-in-concept development project, but the workload was far too much for one person, meaning that we had to apply some rudimentary project management and coordination skills that we had learned to keep the project on track. I quickly became the de-facto PM as I had the best grasp on the project and was doing a lot of the heavy lifting.
The first incident happened while developing a navigation feature. Another teammate had done the basics, all he had to do was use the already-defined interfaces to check where the best place to land would be, taking into account if we had enough power to do so. Mr DDTW's code:
-Wasn't actually an algorithm, just 90 lines of if statements sandwiched between the other teammate's code.
-The if statements were so long that I had to horizontal scroll to see the end, approx 200 characters long per line.
-Could've probably been 20 normal-length lines MAX if he knew what a fucking for loop was.
-Checked about a third of the tiles that it should have because, once again, it's a series of concatenated if statements instead of an actual goddamn algorithm.
-IT DIDN'T FUCKING WORK!
My response was along the lines of "what the fuck is this?". This dipshit is in his final year and I've seen people write better code in their second semester. The rest of the team, his friend included, agreed that this was bad code and that it should be redone properly. The plan was for Mr DDTW to move his code into a new function and then fix it in another branch. Then we could merge it back when it was done. Well, he kept on saying it was done but:
-It still wasn't an algorithm.
-It was still 90 lines.
-They were still 200 characters wide.
-It still only checked a third of the tiles.
-IT STILL DIDN'T FUCKING WORK!
He also had one more task, an infinite loop detection system. He watched while Ms Reliable did the fucking work.
We hit our first of two deadlines successfully. We still didn't have a decent landing function but everything else was nice and polished, and we got graded incredibly well. The other projects had been going alright although the same issue of him not doing shit applied. Ms Reliable and I, seeing the shitstorm that would come if this dude didn't get his act together, lodged a complaint with the professor as a precautionary measure. Little did I know how much that advanced warning would save my ass later on.
Second sprint begins and I'm voted in as the actual PM this time. We have four main tasks, so we assign one person to each and me as a generalist who would take care of the minor tasks as well as help out whoever needed it. This ended up being a lot of reworking and re-abstracting, a lot of helping and, for reasons that nobody ever could have predicted, one of the main tasks.
These main tasks were new features that would need to be integrated, most of which had at least some mutual dependencies. Part of this project involved running our code, which would connect to the professor's test server and solve a server-side navigation problem. The more of these we solved, the better the grade, so understandably we needed an MVP to see if our shit worked on the basic problems and then fix whatever was causing the more advanced ones to fail. We decided to set an internal deadline for this MVP. Guess who didn't reach it?
Hitting the character limit, expect part 2 SOON7 -
it's funny, how doing something for ages but technically kinda the wrong way, makes you hate that thing with a fucking passion.
In my case I am talking about documentation.
At my study, it was required to write documentation for every project, which is actually quite logical. But, although I am find with some documentation/project and architecture design, they went to the fucking limit with this shit.
Just an example of what we had to write every time again (YES FOR EVERY MOTHERFUCKING PROJECT) and how many pages it would approximately cost (of custom content, yes we all had templates):
Phase 1 - Application design (before doing any programming at all):
- PvA (general plan for how to do the project, from who was participating to the way of reporting to your clients and so on - pages: 7-10.
- Functional design, well, the application design in an understandeable way. We were also required to design interfaces. (Yes, I am a backender, can only grasp the basics of GIMP and don't care about doing frontend) - pages: 20-30.
- Technical design (including DB scheme, class diagrams and so fucking on), it explains it mostly I think so - pages: 20-40.
Phase 2 - 'Writing' the application
- Well, writing the application of course.
- Test Plan (so yeah no actual fucking cases yet, just how you fucking plan to test it, what tools you need and so on. Needed? Yes. but not as redicilous as this) - pages: 7-10.
- Test cases: as many functions (read, every button click etc is a 'function') as you have - pages: one excel sheet, usually at least about 20 test cases.
Phase 3 - Application Implementation
- Implementation plan, describes what resources will be needed and so on (yes, I actually had to write down 'keyboard' a few times, like what the actual motherfucking fuck) - pages: 7-10.
- Acceptation test plan, (the plan and the actual tests so two files of which one is an excel/libreoffice calc file) - pages: 7-10.
- Implementation evalutation, well, an evaluation. Usually about 7-10 FUCKING pages long as well (!?!?!?!)
Phase 4 - Maintaining/managing of the application
- Management/maintainence document - well, every FUCKING rule. Usually 10-20 pages.
- SLA (Service Level Agreement) - 20-30 pages.
- Content Management Plan - explains itself, same as above so 20-30 pages (yes, what the fuck).
- Archiving Document, aka, how are you going to archive shit. - pages: 10-15.
I am still can't grasp why they were surprised that students lost all motivation after realizing they'd have to spend about 1-2 weeks BEFORE being allowed to write a single line of code!
Calculation (which takes the worst case scenario aka the most pages possible mostly) comes to about 230 pages. Keep in mind that some pages will be screenshots etc as well but a lot are full-text.
Yes, I understand that documentation is needed but in the way we had to do it, sorry but that's just not how you motivate students to work for their study!
Hell, students who wrote the entire project in one night which worked perfectly with even easter eggs and so on sometimes even got bad grades BECAUSE THEIR DOCUMENTATION WASN'T GOOD ENOUGH.
For comparison, at my last internship I had to write documentation for the REST API I was writing. Three pages, providing enough for the person who had to, to work with it! YES THREE PAGES FOR THE WHOLE MOTHERFUCKING PROJECT.
This is why I FUCKING HATE the word 'documentation'.36 -
This guy I know applied for a senior position at a company I used to do freelance for. He walked in while I was spending the day there to work on our project.
We used to work in the same company and I knew that this guy doesn't know shit. He's the type that would foam in the mouth while bullshitting his way through any sort of discussion.
Anyway, they had him set up on a computer a few tables from me to complete some coding exercises--real simple stuff just to see how he would approach some common problems.
There was no time limit set but the tests shouldn't have taken him more than an hour.
He sat there for SIX HOURS.
At this point, I went out for a smoke, came back 5 minutes later, and found that he wasn't there anymore.
Apparently, he just stood up and said, "Nope, can't do it" and then left the building without a word to anybody else.
We never heard of him again.
Oh, and the tests? Not a single line of code written XD5 -
I've optimised so many things in my time I can't remember most of them.
Most recently, something had to be the equivalent off `"literal" LIKE column` with a million rows to compare. It would take around a second average each literal to lookup for a service that needs to be high load and low latency. This isn't an easy case to optimise, many people would consider it impossible.
It took my a couple of hours to reverse engineer the data and implement a few hundred line implementation that would look it up in 1ms average with the worst possible case being very rare and not too distant from this.
In another case there was a lookup of arbitrary time spans that most people would not bother to cache because the input parameters are too short lived and variable to make a difference. I replaced the 50000+ line application acting as a middle man between the application and database with 500 lines of code that did the look up faster and was able to implement a reasonable caching strategy. This dropped resource consumption by a minimum of factor of ten at least. Misses were cheaper and it was able to cache most cases. It also involved modifying the client library in C to stop it unnecessarily wrapping primitives in objects to the high level language which was causing it to consume excessive amounts of memory when processing huge data streams.
Another system would download a huge data set for every point of sale constantly, then parse and apply it. It had to reflect changes quickly but would download the whole dataset each time containing hundreds of thousands of rows. I whipped up a system so that a single server (barring redundancy) would download it in a loop, parse it using C which was much faster than the traditional interpreted language, then use a custom data differential format, TCP data streaming protocol, binary serialisation and LZMA compression to pipe it down to points of sale. This protocol also used versioning for catchup and differential combination for additional reduction in size. It went from being 30 seconds to a few minutes behind to using able to keep up to with in a second of changes. It was also using so much bandwidth that it would reach the limit on ADSL connections then get throttled. I looked at the traffic stats after and it dropped from dozens of terabytes a month to around a gigabyte or so a month for several hundred machines. The drop in the graphs you'd think all the machines had been turned off as that's what it looked like. It could now happily run over GPRS or 56K.
I was working on a project with a lot of data and noticed these huge tables and horrible queries. The tables were all the results of queries. Someone wrote terrible SQL then to optimise it ran it in the background with all possible variable values then store the results of joins and aggregates into new tables. On top of those tables they wrote more SQL. I wrote some new queries and query generation that wiped out thousands of lines of code immediately and operated on the original tables taking things down from 30GB and rapidly climbing to a couple GB.
Another time a piece of mathematics had to generate all possible permutations and the existing solution was factorial. I worked out how to optimise it to run n*n which believe it or not made the world of difference. Went from hardly handling anything to handling anything thrown at it. It was nice trying to get people to "freeze the system now".
I build my own frontend systems (admittedly rushed) that do what angular/react/vue aim for but with higher (maximum) performance including an in memory data base to back the UI that had layered event driven indexes and could handle referential integrity (overlay on the database only revealing items with valid integrity) or reordering and reposition events very rapidly using a custom AVL tree. You could layer indexes over it (data inheritance) that could be partial and dynamic.
So many times have I optimised things on automatic just cleaning up code normally. Hundreds, thousands of optimisations. It's what makes my clock tick.4 -
VB3.
In my last rant I mentioned I used to convert VB3 code to .Net. Before that, I used to work on the VB3 product itself. This software emulated something from the real world, and as such complied with a bunch of regulations that changed on a regular basis, and always had additions and removals that were to be done on a strict schedule (e.g. "we're adding a new product next month, so we have to be able to sell it by the first of the month"). As such, it was a huge sprawling mess.
One day, I was given a task to change some feature slightly. The task was simple enough and really only required adding one line of code. I added that line and clicked "Run".
Error: Too Much Code
What? What do you mean too much code? I asked a colleague for help. "Oh, don't worry, it happens when a function is too long. Just remove one or two of the comments and try again." The comments were, naturally, old deleted code that was quite meaningless so I had no qualms about removing some. It worked, and I went on with my life.
This started happening on a regular basis on our larger functions. But there were always comments to remove so it wasn't a big issue.
One day, though, it happened on a five-line function. This was puzzling - the error had always happened when a function was too big but this one clearly wasn't. What could the error mean? I went to the same colleague.
Apparently, there's also a limit to how big the entire code base can be. "Just find a function that isn't used any more and delete it." And so I did. There were many such functions, responsible for calculating things which no longer existed so they were never called. For months, I'd find functions and remove them. Until there weren't any more. I checked every function and subroutine in our codebase, and they were all used; I checked every possible code path and they were all needed.
What do I do now, I asked? The colleague, who was an expert on VB3 but worked on another project, came and take a look.
"Look at all these small functions you made! No wonder you're running out of space!" Apparently each function created a lot of overhead in the compiled executable. The solution was clear. Combine small functions into large monolithic ones, possibly passing flags in them to do completely unrelated things. Oh, and don't comment on the different parts because we have no room for comments in our code base.
Ah, the good old days.5 -
Today my manager got mad at me because of something i said....
Dude i just jokingly said that i didn't appreciate her attitude. Like that was it
The thing is, she didn't get mad at me in a 'i am your boss and you were out of line way"
It was more of a....gf...kind of getting mad sort of deal....and it was really odd.
I know the difference. But either way I only know how to act in 2 ways: make the girl happy or not give a fuck about it.
So i just apologized.
I already got a wife and 2 daughters to keep happy.
There is a limit my dudes, for the ammount of women a straight male can keep happy.15 -
I really wanna share this with you guys.
We have a couple of physical servers (yeah, I know) provided by a company owned by a friend of my boss. One of them, which I'll refer to as S1, hosted a couple of websites based on Drupal 7... Long story short, every php file got compromised after someone used a vulnerability within D7's core to inject malicious code. Whatver, wasn't a project of mine, and no one bothered to do anything about it... The client was even happy about not doing anything about it. We did stop making backups of such websites however, to avoid spreading the damage (right?). So, no one cared about this for months!
But last monday? The physical server was offline. I powered it on again via its web management interface... Dead after less than an hour. No backups. Oh well, I guess I couls keep powering it on to check what's wrong with it and attempt to fix it...
That's when I've learned how the web management interface works: power on/reboot requests prompted actual workers to reach the physical server and press the power on/reboot buttons.
That took a while to sink in. I mean, ok, theu are physical servers... But aren't they managed anyhow? They are just... Whatever. Rebooting over and over wasn't the solution, so I asked if they could move the HDD to another of our servers... The answer was it required to buy a "server installation" package. In short, we'd have had to buy a new physical server, or renew the subscription of one we already owned for 6 months.
So... I've literally spent the rest of the day bothering their emoloyeea to reboot S1, until I've reached the "daily reboot reauests limit" (which amounts to 3 reauests. seriously), whicj magically opened a support ticket where a random guy advised to stop using VNC as "the server was responsive" and offeres to help me with the command line.
Fiiine, I sort of appreciate it. My next message has been a kernel log which shows how the OS dying out was due to physical components becoming unavailable after a while, and how S1 lacked a VNC server, being accessible only via ssh. So, the daily reboot limit was removes for S1. Yay.
...What to do though? S1 was down, we had no backups, and asking for manual rebooting every time was slow as Hell. ....Then I went insane. I asked for 1 more reboot. su. crontab -e. */15 * * * * /sbin/shutdown -r +5. while true; do; rsync --timeout=20 --append S1:/stuff .; sleep 60; done.
It worked. We have now again access to 4 hacked, shitty Drupal 7 websites. My boss stopped shouting. I can get back to my own projects.
Apparently, those D7 websites got back online too, still with malicious php code within them. Well, not my problem (for now).
Meanwhile, S1 is still rebooting.3 -
So... did I mention I sometimes hate banks?
But I'll start at the beginning.
In the beginning, the big bang created the universe and evolution created humans, penguins, polar bea... oh well, fuck it, a couple million years fast forward...
Your trusted, local flightless bird walks into a bank to open an account. This, on its own, was a mistake, but opening an online bank account as a minor (which I was before I turned 18, because that was how things worked) was not that easy at the time.
So, yours truly of course signs a contract, binding me to follow the BSI Grundschutz (A basic security standard in Germany, it's not a law, but part of some contracts. It contains basic security advice like "don't run unknown software, install antivirus/firewall, use strong passwords", so it's just a basic prototype for a security policy).
The copy provided with my contract states a minimum password length of 8 (somewhat reasonable if you don't limit yourself to alphanumeric, include the entire UTF 8 standard and so on).
The bank's online banking password length is limited to 5 characters. So... fuck the contract, huh?
Calling support, they claimed that it is a "technical neccessity" (I never state my job when calling a support line. The more skilled people on the other hand notice it sooner or later, the others - why bother telling them) and that it is "stored encrypted". Why they use a nonstandard way of storing and encrypting it and making it that easy to brute-force it... no idea.
However, after three login attempts, the account is blocked, so a brute force attack turns into a DOS attack.
And since the only way to unblock it is to physically appear in a branch, you just would need to hit a couple thousand accounts in a neighbourhood (not a lot if you use bots and know a thing or two about the syntax of IBAN numbers) and fill up all the branches with lots of potential hostages for your planned heist or terrorist attack. Quite useful.
So, after getting nowhere with the support - After suggesting to change my username to something cryptic and insisting that their homegrown, 2FA would prevent attacks. Unless someone would login (which worked without 2FA because the 2FA only is used when moving money), report the card missing, request a new one to a different address and log in with that. Which, you know, is quite likely to happen and be blamed on the customer.
So... I went to cancel my account there - seeing as I could not fulfill my contract as a customer. I've signed to use a minimum password length of 8. I can only use a password length of 5.
Contract void. Sometimes, I love dealing with idiots.
And these people are in charge of billions of money, stock and assets. I think I'll move to... idk, Antarctica?4 -
A jr colleague came back from a react.js code camp.
Those hipsters turned the poor kid into a one liner terrorist and buzzword spammer.
It's time to play bad cop and start enforcing line length limit. -
We just had a big drama because our team leader discovered 2 of our projects use 79 character line limit. He changed it to 80 and reformatted all the code.
What is wrong with this world?9 -
I dunno about coolest, but I did sort of cement my reputation as the "database guy" in my first job because of this.
My first job was with a group maintaining a series of websites. Because of the nature of the websites, every morning we had to pull the records from one database on one network, sneaker net the data to a database on another network, and import the data via custom data import function.
However, the live site would crash after 100 or so records were imported. The dba at the live site had to script out a custom data partitioning script to do his daily duties, but it definitely messed up his productivity.
Turns out, the custom mass import function had recycled the standard import function, which was only used to import 1 record at a time, and it never closed its database connections, because it never needed to. A one line fix to production code was delivered 6 months later (because that was our release cycle) and I came up with the temporary work around, which was basically removing the connection limit. It would still crash with the work around, but only with multiple days worth of data. So basically only on Monday. Also developed the test set for the import (15k+ records). -
Fuck pep8 in general. Fuck harder anything to do with line limits. Fuck with a rusty spatula those who tie it into their git precommits or CI tests.
What's that, it's 2018 and even the shittiest walmart-tier computers have 1080p OR BETTER at a 16:9 aspect ratio?
"lol, 80 character line limit."
Eat a bucket of rancid dicks.
Oh, and since we're forcing you to be so economical with your characters, we're going to force four space tabs. Yknow, rather than simple single tab characters, which could mean everyone can set their preferred level of spacing without bloating the code with whitespace.
Because, yknow, it's entirely reasonable to chew up 1/8 of a line because you're editing a function inside a class definition. God Almighty forbid you try to do a for loop inside that function! Fuck you!
"Oh but you can't have two editors or terminals open side by side without that limit!"
BULL FUCKING SHIT. Here's my shitty 1280x1024 display on my shitty computer with two Sublime editors open side by side. You'll notice the break is at 100 characters. You'll notice I don't have to scroll horizontally to do two things at once. You'll notice I even have room for COMMENTS!
If your code standards require you to make your code *less* readable and *less* clear and take up *more* space to accomplish the same tasks, YOUR CODE STANDARDS SUCK!
Enough with this stupid meme. We're not in the 80s anymore and it's high time to start fucking acting like it.7 -
Okey, so the recruiters are getting smarter, I just clicked how well do you know WordPress quiz (I know it's from a recruiter, already entered a php quiz An might win a drone)
So the question is how to solve this issue:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 2348617 bytes) in /home4/xxx/public_html/wp-includes/plugin.php on line xxx
A set memory limit to 256
B set memory limit to Max
C set memory limit to 256 in htaccess
D restart server
These all seem like bad answers to me.
I vote E don't use the plug-in, or the answer that trumps the rest, F don't use WordPress4 -
First real dev project was a calculator for a browser game, that calculates the optimal number/combination of buildings to build. I got bored constantly doing it manually, so I made this program as a fun and useful challenge. It involved basic math, and I did it in VB.
Second one was a stats tracking page for my team in another browser game, that let us easily share and keep track of stuff. It allowed us to minmax our actions and reduced the downtime between actions of different players. HTML, CSS, JS, PHP, MySQL.
Third one was a userscript for the same game that added QoL features and made the game easier to play. JS
Fourth was for the first game, also a QoL feature userscript, that added colors/names, number limit validation to inputs, and optimization calculators built in the interface. It also fixed and improved various UI things. Also had a cheating feature where I could see the line of sight of enemies in the fog of war (lol the dev kept the data on the page even if you couldnt see the enemies on the map), but I didnt use it, it was just fun to code it. JS
From there on, I just continued learning and doing more and more complex shit, and learning new languages.2 -
** this means words are muted **
Friday:
I send a mail the client a Google doc with elaborate details about evaluation of an Android tablet from a Chinese manufacturer.
Monday:
The client is upset, he says "You say there is no GPS chip on the tablet while the manufacturer says otherwise"
Me- "I have clearly mentioned that it has a GPS chip"
Client- Opens the Google doc, points to a sentence. Looks at me like I did something horrible.
Me - **This guys is either word blind or something else is wrong with him, the line reads 'GPS chip available'**
Me- "Look, it says 'GPS chip available'.
Client- **Blinks n blinks again** "Alright, but why did you share a Google document, why not PDF, docx"
Me-**Politely** "You can download the document in any format, look I will show you..."
Client- "It should have been in the mail itself ideally"
Me- **WTH** "We normally maintain a document for such things to keep everything organised, but if you want I will put everything in mail itself"
Client- "Hmm.. do both from next time"
Me- "Alright" **BS**
Client- "Why is the new feature taking so much time"
Me- "As planned earlier, we going to deliver it tomorrow"
Client- "Why not today??" **Gives a strange look.**
Me thinking - **Enough**
Me- "See, I am trying to integrate a smarten with a socket connection, reading it's data via exposed APIs that are hardly documented, we need faster performance so I need to implement caching, multi threading, offline handling, multiple processes to avoid memory fluctuations, sync adapter to sync data...."
Client- "Ok ok ok, it's fine if you give working build tomorrow"
Me- "Ok, fine"

not dev.
A follow up on my HSBC credit increase rejection rant from last month. So they ended up saying "we chose not to give you an increase even though your account is very good. Feel free to try again in 3-6 months but I can't guarantee your request will be approved."
I let it be.
Today I got an email saying that following a recent review of my account, they'd like to offer me an increase. The same increase I asked for last month and got rejected, and then had my credit score ruined over. Bitch what.
I am petty af, tomorrow I'll call them and tell them that "after having reviewed their services, I choose not to give them consent to increase my credit limit. I understand this isn't the outcome they were hoping for, but that is my decision. Feel free to reach out again in 3-6 months but I can't guarantee that I'll change my mind. "
Yes I know the rep on the other end of the line wouldn't give a f*ck, I just want that recorded. I don't really need the increase, just wanted to lower my utilisation. They can suck it.2 -
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.
QED.
If I've made a mistake, I'd like to know.11 -
This is gonna be a long post, and inevitably DR will mutilate my line breaks, so bear with me.
Also I cut out a bunch because the length was overlimit, so I'll post the second half later.
I'm annoyed because it appears the current stablediffusion trend has thrown the baby out with the bath water. I'll explain that in a moment.
As you all know I like to make extraordinary claims with little proof, sometimes
for shits and giggles, and sometimes because I'm just delusional apparently.
One of my legit 'claims to fame' is, on the theoretical level, I predicted
most of the developments in AI over the last 10+ years, down to key insights.
I've never had the math background for it, but I understood the ideas I
was working with at a conceptual level. Part of this flowed from powering
through literal (god I hate that word) hundreds of research papers a year, because I'm an obsessive like that. And I had to power through them, because
a lot of the technical low-level details were beyond my reach, but architecturally
I started to see a lot of patterns, and begin to grasp the general thrust
of where research and development *needed* to go.
In any case, I'm looking at stablediffusion and what occurs to me is that we've almost entirely thrown out GANs. As some or most of you may know, a GAN is
where networks compete, one to generate outputs that look real, another
to discern which is real, and by the process of competition, improve the ability
to generate a convincing fake, and to discern one. Imagine a self-sharpening knife and you get the idea.
Well, when we went to the diffusion method, upscaling noise (essentially a form of controlled pareidolia using autoencoders over seq2seq models) we threw out
GANs.
We also threw out online learning. The models only grow on the backend.
This doesn't help anyone but those corporations that have massive funding
to create and train models. They get to decide how the models 'think', what their
biases are, and what topics or subjects they cover. This is no good long run,
but thats more of an ideological argument. Thats not the real problem.
The problem is they've once again gimped the research, chosen a suboptimal
trap for the direction of development.
What interested me early on in the lottery ticket theory was the implications.
The lottery ticket theory says that, part of the reason *some* RANDOM initializations of a network train/predict better than others, is essentially
down to a small pool of subgraphs that happened, by pure luck, to chance on
initialization that just so happened to be the right 'lottery numbers' as it were, for training quickly.
The first implication of this, is that the bigger a network therefore, the greater the chance of these lucky subgraphs occurring. Whether the density grows
faster than the density of the 'unlucky' or average subgraphs, is another matter.
From this though, they realized what they could do was search out these subgraphs, and prune many of the worst or average performing neighbor graphs, without meaningful loss in model performance. Essentially they could *shrink down* things like chatGPT and BERT.
The second implication was more sublte and overlooked, and still is.
The existence of lucky subnetworks might suggest nothing additional--In which case the implication is that *any* subnet could *technically*, by transfer learning, be 'lucky' and train fast or be particularly good for some unknown task.
INSTEAD however, what has happened is we haven't really seen that. What this means is actually pretty startling. It has two possible implications, either of which will have significant outcomes on the research sooner or later:
1. there is an 'island' of network size, beyond what we've currently achieved,
where networks that are currently state of the3 art at some things, rapidly converge to state-of-the-art *generalists* in nearly *all* task, regardless of input. What this would look like at first, is a gradual drop off in gains of the current approach, characterized as a potential new "ai winter", or a "limit to the current approach", which wouldn't actually be the limit, but a saddle point in its utility across domains and its intelligence (for some measure and definition of 'intelligence').4 -
When you have a long line like this...
if ($obj->getStupidlyLongNamedThing() + $hard + $harder * $hard / $harder + $obj->getAlsoStupidLongThing([$sillyLongExpression, $thing]) > $obj->omgThisIsInsane());
If you're just going to be lazy and break it up however where where ever so it looks like crap...
if ($a->b()
____&& $a->c());
Then I urge you to do one of two things:
* Shut up your face and turn on word wrap in the IDE rather than manually doing it even worse.
* Break the long parts into variable assignments or something.
* (or get a wider screen)
Example:
$a = $obj->getStupidlyLongNamedThing();
$b = $hard + $harder * $hard / $harder;
$c = [$sillyLongExpression, $thing];
$d = $obj->getAlsoStupidLongThing($c);
$e = $obj->omgThisIsInsane();
if ($a + $b + $d > $d);
With sensible variable names.3 -

Why the FUCK do bank waiting lines have to be so fucking long? And why do these old cunts have to spend 30+ minutes in the booth each? If this goes on, I'll have to wait in line for THREE FUCKING HOURS just to raise my fucking daily transaction limit! And all I fucking wanted was to order the parts for my new goddamn rig! If you have too many cocking clients to handle, hire an extra worker or five!2 -
So...buffered query kept crashing even though I have a row limit of 10001 on my abstract datatables class. I didn't realize it was buffered because I grab the results in a for loop as a fetch. Well, I tracked it down to being the size of the email content that I'm selecting (and then using strip_tags and substring in PHP before returning to the front-end). So it's totally a catch-22 at this point because if I select let's say...substring 500 characters and most of that is line breaks and other html junk, I may only get a couple characters of normal text (or none at all) after stripping tags and doing a final substring to get the 50 characters of text I want to display. I said screw it and took the email content out of the table all together. You have to view it to see the content now. I should probably be storing a text-only version of the email, but argh..that's a lot of extra data.

Did I randomly hallucinate that 74 or 75 characters used to be a popular line length limit? I've been using 74 ever since I learned what a formatter is because it was the smallest number I heard of until then, but now I can't find any source for this.
Before anyone complains, I prefer short lines whenever I get a say because my eyes are pretty bad and I want to be able to use a large font on a 14" laptop.12 -
Wish me luck.
Deploying Blazor app for the first time in prod in about a month.
Did tests. Curent infrastructure can hold around 70 concurent sessions with no problems. (probably more, 70 was the limit in my browser).
I tested each sessiuon with 70.000 line table. (Yep whole 70.000 lines for each session with a virtual scroll).
Shit is fast. Too fast even. I'm waiting for other shoe to drop, but so far in simulated tests it's amazing.
Let's talk in 2 month AFTER prod deploy.4 -
i have been watching some jetpack compose tutorials and trying to create projects with it. Its quite cool and looks very interesting. but wrti8 those modifiers seems like a great wastage of time :/
Also, i have an OCD of writing code in lesser number of lines , as much as possible . so i would rather prefer writing
val x = Modifier.function1().fun2().fun()
than
val x = Modifier
.function1()
.fun2()
.fun()
as long as my code line does not cross the 80 character limit guideline, and as long as it makes sense to not switch to a new line.
but IDE seems adamant on breaking those long modifier lines to weird indented codeblock, so its already getting very noring for me :/2 -
Linux vs Windows (vs AnyOtherOS) | The Age Old Question
The short answer: It depends. And probably isn't even up to you to choose
The long answer:
No one's forcing you to choose. And you have more than 2 options. (The 3rd being... both. (Unless you're running out of hardware))
You have to mentally replace "Which is better? Linux or Windows?" with "Which one gets me sooner to a completed task that more closely matches the end-user's expectations"
If it's something you're developing for yourself, then use whatever the hell you want, because you know where you want that "finished product" to be used, and in what manner.
But often, everyone around you and their cats are not using what you're using
Have to write a document? Oh.. there's this blue program thingy (no one talks like that), I think it was called "Microsoft Word"
Oh, you don't have that?? How the hell do you edit documents then?
~ Some employer still using MS Word 2009
"I'll send you the PSD", "Make it a PSD", "You need the PSD file for reference, right?"
psd? More like PTSD at this point
It's like Photoshop is suddenly the only way to edit images, oh.. and Paint.
* Use paint. I don't care. If it gets the job done, do it.
Hate Photoshop? Love Gimp? Too bad.
When that god forsaken PSD is emailed to you, you better have a copy of Windows and Photoshop just in case it looks like garbage in.. OR OUT of gimp..
Bottom Line:
Don't use what people use. Just have everything ready in case your boss still uses MS Word 1839 and you want to ENSURE, it'll look the same on his screen
*It's wrong to limit yourself to just ONE SINGLE OS2 -
line breaks after 100 or so characters suck. function chaining will look bad in one line, but it doesn't mean we need to limit all our lines to a hard length.
ex:
config.logger.e(TAG, "func() called with: p1 = $p1, p2 = $p2, p3 = $p3, p4 = $p4, p5 = $p5")
this is a standard log that i add at the start of my functions . its easy to autogenerate in intellij , even if my class and variable names are much long (like mVideoAnalyticsManager) . when these variables and their string names add up, they will easily go out of the screen and i won't mind scrolling a few seonds to the left to ensure everything is correct (which 99.9% is)
but a fucking ctrl+alt+l and all strings are broken with a fucking +
