Programming

If you don't add comments, even rudimentary ones, or you don't use a naming convention that accurately describes the variables or the functions, you're a bad programmer. It doesn't matter if you know what it does now, just wait until you need to know what it does in 6 months and you have to stop what you're doing an decipher it.

Not sure if these are hot takes:

• Difficult to test == poorly designed
• Code review is overrated and often poorly executed, most things should be checked automatically (review should still be done though)
• Which programming language doesn't matter (within reason), while amount of programming languages matters a lot

Compiler checked typing is strictly superior to dynamic typing. Any criticism of it is either ignorance, only applicable to older languages or a temporarily missing feature from the current languages.

Using dynamic languages is understandable for a lot of language "external" reasons, just that I really feel like there's no good argument for it.

My take is that no matter which language you are using, and no matter the field you work in, you will always have something to learn.

After 4 years of professional development, I rated my knowledge of C++ at 7/10. After 8 years, I rated it 4/10. After 15 years, I can confidently say 6.5/10.

The best codebase I have ever seen and collaborated on was also boring as fuck.

• Small, immutable modules.
• Every new features was coded by extension (the 'o' in S.O.L.I.D)
• All dependencies were resolved by injection.
• All the application life cycle was managed by configurable scopes.
• There was absolutely no boiler plate except for the initial injectors.
• All of the tests were brain-dead and took very minimal effort to write. Tests served both as documentation and specification for modules.
• "Refactoring" was as simple as changing a constructor or a configuration file.
• All the input/output of the modules were configurable streams.

There is more to it, but basically, it was a very strict codebase, and it used a lot of opinionated libraries. Not an easy codebase to understand if you're a newbie, but it was absolutely brain dead to maintain and extend on.

Coding actually took very little time of our day, most of it consisted of researching the best tech or what to add next. I think the codebase was objectively strictly better than all other similar software I've seen and worked on. We joked A LOT when it came time to change something in the app pretending it would take weeks and many 8 pointers, then we'd casually make the change while joking about it.

It might sound mythical and bullshity, and it wasn't perfect, it should be said that dependency injection often come in the form of highly opinionated frameworks, but it really felt like what software development should be. It really felt like engineering, boring and predictable, every PO dreams.

That being said, I given up trying to convince people that having life-cycle logic are over the place and fetching dependencies left and right always lead to chaos. Unfortunately I cannot really tell you guys what the software was about because I am not allowed to, but there was a lot of moving parts (hence why we decided to go with this approach). I will also reiterate that it was boring as fuck. If anything, my hot take would be that most programmers are subconsciously lying to themselves, and prefer to code whatever it is they like, instead of what the codebase need, and using whatever tool they like, instead of the tools the project and the team need. Programming like and engineer is not "fun", programming like a cowboy and ignoring the tests is a whole lot of fun.

I am not smart enough to effectively code with certain languages and design patterns and that's ok. There is nothing wrong with accessibility being prioritized or with making tradeoffs for the sake of reducing complexity.

Computer hardware has been getting faster and faster for decades at this point, but my computer still slows down. Like WTF. The dumbass programmers take the extra power given to them and squander it instead of optimizing their code. Microsoft word could run pretty well on a windows 98 PC, but the new Word can slow down PCs that are 5-10 years old. Programmers are complete idiots sometimes...

Refactoring is something that should be constantly done in a code base, for every story. As soon as people get scared about changing things the codebase is on the road to being legacy.

Dynamic typing is insane. You have to keep track of the type of absolutely everything, in your head. It's like the assembly of type systems, except it makes your program slower instead of faster.

Programing is a lot less important than people and team dynamics

Python is only good for short programs

Agile in it’s current implementation with excessive meetings wastes more time than the mistakes it tries to avoid.

SPAs are mostly garbage, and the internet has been irreparably damaged by lazy devs chasing trends just to building simple sites with overly complicated fe frameworks.

90% of the internet actually should just be rendered server side with a bit of js for interactivity. JQuery was fine at the time, Javascript is better now and Alpinejs is actually awesome. Nowadays, REST w/HTMX and HATEOAS is the most productive, painless and enjoyable web development can get. Minimal dependencies, tiny file sizes, fast and simple.

Unless your web site needs to work offline (it probably doesn't), or it has to manage client state for dozen/hundreds of data points (e.g. Google Maps), you don't need a SPA. If your site only needs to track minimal state, just use a good SSR web framework (Rails, asp.net, Django, whatever).

Using single character variable names is always bad practice

Tools that use a GUI are just as good (if not better) than their CLI equivalents in most cases. There's a certain kind of dev that just gets a superiority complex about using CLI stuff.

Go with what works

Error messages should contain the information that caused the error. Your average Microsoft error "error 37253" is worthless to me

Keep functions or methods short. Anything longer than 20 - 50 lines is likely too long

Comment why is happening, not what

PHP is actually a really nice language to work with both for web and command line utils

Don't over engineer, KISS. Keep It Simple Stupid

SOLID is quite okay but sometimes there are solid reasons to break those rules

MVC is a PITA in practice, avoid it when possible

Internet would be better if javascript was never invented.
