There is some confusion about my meaning, so let me write yet another thread expanding on it that most people replying won't see. I don't just mean in the sense of "it's an indie game, fuck it, if it works, ship it". I mean in the sense that this is stylistically correct. (1/n)

Classic bad advice: "I was successful, so everyone should do that I did." I've seen many GDC talks where game companies who succeeded with their 1st game attribute that success to specific business or design choices they made, even though that conclusion is totally unjustified.

Criticisms of the code mostly fall in two camps: performance, and style. Performance is irrelevant. It's written in the interpreted language Lua, it does multiple hash table lookups per if, but that doesn't matter, it runs once per frame, computers are fast.

Protip: In C, allocate arrays with malloc/calloc using sizeof() the variable, not the type: foo *arr = malloc(num_arr * sizeof(arr[0])); not foo *arr = malloc(num_arr * sizeof(foo)); If you change the type of 'arr', the first is still correct, the second is wrong.

I find hiding pointerness behind typedefs reduces clarity. But it was many years into my C programming career that I learned you didn't have to do typedef void (*callbackType)(int x); callbackType mycb; but could instead: typedef void (callbackType)(int x); callbackType *mycb;

Okay so this is wild. I just got a call and voicemail from an attorney who is calling to complain about content in a video game that “his son and his friends are playing” (Conan Exiles) - Weird. 1/

New library for C programmers (not interesting for C++ programmers): extending the "stretchy_buffer" stb_arr API metaphor to HASH TABLES. Based on idea by @pervognsen Preview release, has done lots of testing and tuning but may still have bugs!

@bnoob_ I think because the tone I took in my final reply (which wasn't the point of the tweet anyway, I just included it for fun) is a counter-productive tone to take as it is likely to annoy maintainers & make them choose not to do anything. Of course I knew that and did it anyway.

Me, reading the JSON specification, and finding out that what is AFAICT essentially the most-used text-based serialization format intended for generation BY SOFTWARE does not technically allow trailing commas in arrays and objects:

TFW the compute shader that took 3-4ms/frame two days ago (w/video proof!) now takes 10-12 ms, & you haven't really changed anything, so you check out an old version and it's also 10-12 ms, and you reboot your computer, still 10-12 ms, and you haven't updated drivers or anything.

I remain miffed that I spent all the 90s typefing an int32 instead of assuming that int was 32-bits, because that was good practice, and then when we went 64-bits, we ended up with the convention that ints were staying 32 bits, largely because too much int-using code would break.

Protip: on Windows browsers, alt-drag link text to select without clicking link Protip: In text editors, press 'undo' then 'redo' to move cursor to location of last edit. Protip: make C function signatures w/o pointer: typedef int foo(int bar); void myfunc(foo *callback);

New library: stb_hexwave.h A new kind of audio synthesis. It's not subtractive, it's not additive, it's not FM synthesis. If I have to name it: line segment synthesis? Band-limited (anti-aliased) w/ BLEP & BLAMP. On my github as always. Audio demo:

AFAICT this is basically just "sandbox Facebook from everything else", so then the question becomes: when do we get the browser that just sandboxes everything from everything else?

This is genius: Leaving Facebook isn't an option for everyone, so Firefox's new Facebook Container Extension lets you continue using Facebook, but quarantines your identity into a container that third-party cookies and trackers can't touch.

Since 33 mutuals of mine follow Rich Geldreich, I should point out that as far as I can tell, he's just making stuff up about RAD and pretending it's magical insider knowledge, so I wouldn't trust his discussion of ANY company or its internals.

Despite RAD having already explained to @richgel999 that they've never been bailed out, he continues to claim RAD was bailed out. What bailout? When did this happen? Who bailed them out? It's nonsense. It is extremely irresponsible to blatantly lie repeatedly to 12k+ followers.

In games, we rarely get to clean up code bases as @Jonathan_Blow is doing with Braid, 95 to 69 KLoC so far (3 days).
