Does anyone remember when something like this actually happened? Maybe it’s the Mandela effect but U sweat at one stage a whole heap of sites were using black/dark mode to save the planet
You only hurt yourself down the line. My last job had not improved their own product, processes, tools or frameworks, so everything was still stuck in the 90s. Their product was build on an discontinued an proprietary database and server system you never heard about, jQuery UI from 10 years ago and other BS.
However if you don’t upskill yourself in this situation you will be unemployable in the future, because all other employers demand modern technologies, git, docker, unit testing etc., which I was yelled at in meetings for suggesting it.
The Lead Dev/team Lead was quite arrogant and in his own mind the worlds best developer who had all the answers. If some technology or software was not written by him or already existed in the 90s it was “useless” and not fit for the company (without him having looked at it or the docs). If asked why we would not use X which was out for years, well maintained, had no critical bugs would solve problem Z we where having, he would reply “because i said so” and insist in writing out own variant - which ended up having 10% of the features, 10 times the bugs, terrible UI and would take months to develop.
When support repeatetly told him that users had issues with feature X because the only error message on a 10 fields forms page was “Error”, he would respond that this is a user problem, the end user is clearly stupid (despide used in a field where you need to study for years) and that support must hold training sessions so the users can “learn” how to use his product.
As such, the company would reject git and instead email each other files and changes.
Each meeting felt like living inside a Dilbert cartoon.
It’s more modern than Visual Source Safe, that’s for sure. I kind of miss the days of coworkers leaving for two-week vacations and forgetting to check their shit in first. It was a built-in excuse for the rest of us to not do anything and blame it all on vacation boy.
Git wasn’t used all that much in the 2000s. As far as I know it became popular in the 2010s (though it was always a thing in some circles I think) and then just supplanted almost everything else.
Also keep in mind some shops tend to follow larger tech companies (microsoft, etc.) and their product offering. So even new products might not have been on git until MS went in that direction.
There are a lot of employers that’ll throw good money at you for maintaining and extending their outdated crap. Have you ever considered learning COBOL?
The thing people always overlook is that these legacy systems are only still running because they’re super important. Nobody’s hiring a junior COBOL dev to maintain NORAD, and hopefully nobody’s contemplating putting ChatGPT in charge either.
The move if you want this kind of job is to learn a language that’s not quite a dinosaur yet, and have 20 years experience in 20 years. Perl or PHP maybe.
Recently switched jobs from maintaining a 15 year old Windows Forms .NET Framework legacy codebase.
At the new job we stick to Clean Architecture, use unit and integration tests, have a code generation tool, actually make nice use of generics and use dependency injection. Also agile processes, automatic build tools, whatever. The difference is night and day and I’m so glad my ex boss fired me because I told him he’s an asshole and his codebase is shit.
My first job out of college I have been able to see a steady improvement in the codebase. A little while ago I had to go back to an old tag and was horrified with what it used to be and impressed how much it improved.
At the simplest, it takes in a vector of floating-point numbers, multiplies them with other similar vectors (the “weights”), sums each one, applies a RELU* the the result, and then uses those values as a vector for another layer with it’s own weights (or gives output). The magic is in the weights.
This operation is a simple matrix-by-vector product followed by pairwise RELU, if you know what that means.
Where modelWeights is [[[Float]]], and so layer has type [Float] -> [[Float]] -> [Float].
RELU: if i>0 then i else 0. It could also be another nonlinear function, but RELU is obviously fast and works about as well as anything else. There’s interesting theoretical work on certain really weird functions, though.
Less simple, it might have a set pattern of zero weights which can be ignored, allowing fast implementation with a bunch of smaller vectors, or have pairwise multiplication steps, like in the Transformer. Aaand that’s about it, all the rest is stuff that was figured out by trail and error like encoding, and the math behind how to train the weights. Now you know.
Assuming you use hex values for 32-bit weights, you could write a line with 4 no problem:
That’s cool, though honestly I haven’t fully understood, but that’s probably because I don’t know Haskell, that line looked like complete gibberish to me lol. At least I think I got the gist of things on a high level, I’m always curious to understand but never dare to dive deep (holds self from making deep learning joke). Much appriciated btw!
Yeah, maybe somebody can translate for you. I considered using something else, but it was already long and I didn’t feel like writing out multiple loops.
No worries. It’s neat how much such a comparatively simple concept can do, with enough data to work from. Circa-2010 I thought it would never work, lol.
Only 1288 lines? Can I raise you a 6000+ lines stored procedure that calls to multiple different sql functions that each implements a slightly different variation of the same logic?
