10 PRINT "HELLO"
20 GOTO 10
RUN

It was the late 80's or early 90's, I was around 10 years old, and my jaw dropped when I typed this on the Atari 800XL my parents had just given to me.
Hooked ever since :)

Juste before the smartphone explosion (~2008), I was working on a virtual machine for Windows Mobile, Symbian, Android 1.0, and basically every feature-phone of the time.

The VM (coded on good ol' C) would interpret a bunch of HTML, JS, CSS files (more or less like a browser) to run some tiny widgets above the phone's UI, basically allowing us to make multi-platform, custom UIs for low-end phones.

Everything was coded from scratch (except the JS engine which was a fork of SpiderMonkey), the VM could run multiple instances of itself, took around ~2MB of RAM to run (the exe contained everything in 1MB).

Oh, and we were a team of 3 beginner developers.

Fun times, no sleep times ❤️

Craig: We’ve redesigned the Dock ❤️

Me: self.layer.cornerRadius = 8 💩

❤️ Swift ❤️

"Module compiled with Swift 5.1.3 cannot be imported by the Swift 5.2.4 compiler"

but srsly

The best documentation evar for *nix open-source projects on GitHub:

$ make

❤️ Swift ❤️

for (i = 0; i < polygon.count; i++) {
// some print statement
} **

This highly advanced and futuristic piece of code made the Swift compiler eat 14+ GB of RAM while trying to syntax-highlight, before crashing my 8 GB-equipped Macbook.

** yeah, "C-style 'for' loopz syntaxx deprecated since Swift 3 blah blah". Let's reinvent an industry-standard for no goddam reason, because Swift is the FUTURE, oh, and because fuck you by the way.

❤️ Swift ❤️
A new minor version of the compiler has been released !
How sweet !
Which comes with the latest Xcode, which is of course mandatory to deploy on your devices !
How cool !
Let me also break all your code because I've decided to change some obscure programming paradigm, and also because FUCK YOU.

❤️ Xcode ❤️

Build succeeded with 8 warnings and 231 errors.

❤️ Swift ❤️
Compiling fails due to many inter-dependent errors (think database deadlocks).
1 - Comment the code that produces the "locking" error.
=> Code compiles.
2 - Uncomment the code that produces the "locking" error.
=> Code compiles.

My peepee hard
