It’s got a consistent ~1200 monthly active users. Don’t know how many finish each puzzle, but it seems like a lot of people play (and finish) every day

The header technique described towards the beginning of my article is effectively that.

Ok, here's the new way I recommend to do type safe generics in C.

It's cleaner compared to my old function-pointer-cast approach, avoids the undefined behavior everyone is so paranoid about, and doesn't require typeof()

Hacked together a weird spiral Mario game prototype

I haven't, thanks for the link.

I used to do that too, but it became problematic in a large, long lived, multi-engineer codebase

As a precursor to public key cryptography, William Jevons said in 1874 "What two numbers multiplied together produce 8616460799? I think it unlikely that anyone but I will ever know"

Modern computers find the answer in 0.004s: primes 89681 and 96079

Cool for the time, just needed bigger numbers!

I like this comment in the source of /usr/bin/dtruss. It provides context with a "Hey dorks, don't mess with my code" kind of energy.

Weird time to be someone that likes making tools

Haha so true!

Not a good sign when fixing a bug requires editing a file with this at the top

This was written by a filmmaker about color science, but it applies just as well to the software industry's dependency problem

I ended up doing this: github.com/floooh/sokol...

Github needs this notification option

Tired of getting pinged every time a random person adds their two cents to a Github issue I follow.

I've had that sitting on my games shelf for years but haven't played it, maybe I never will now!

@flohofwoe.bsky.social Is there a trick to get alpha blending working in sokol-gl, or does that require making my own pipeline?

aka:
sgl_begin_triangles();
sgl_c4b(255, 0, 0, 127);
...
sgl_end();

It’s wild that iOS still doesn’t have a “lock orientation *except videos*” mode

That was really nice. I recently realized I haven’t been playing guitar as much I used to, so I’m trying to fix that.

haha yeah, I wasn’t sure how far to take the meme…could have included micro architecture all the way down to electrons!

"C is how a computer actually works"

TIL that CRT "pixels" can have only a portion illuminated, unlike LCD pixels. (Seen on the top and bottom edge of this 'P')

Today I bought an old TV for visual reference. Played Balatro to see how the game's CRT emulation compared to a real Cathode Ray Tube. Sadly details aren't legible on a 13" TV, and the emulation's scanline/phosphor pattern isn't realistic, but it nails the chromatic aberration.

Already exists! “Space” toggles pencil. “Shift + a number” edits pencil digits regardless of pencil mode.

The bottom middle 4 and the 8 are disambiguated by the cell to the NE of the center 7 – in other words it has one solution but you made a mistake by filling in the 4/8 cells too early.

Colors don't mean anything.

135,000 Github projects mention "blazing fast" in the readme, but only 3,000 of those mention "benchmark" or "MB/s".

So in other words, when you read "blazing fast" think "unserious".

My article titles keep getting longer. I don't know what to make of this.

I never wrote a version that uses `Set`, so I don't know. Coming from C, I just reach for bitmasks first.

Agreed. A sudoku setter contacted me today about creating a cracked sudoku, will post about that when it's done!

I'd guess that 93.732% of JavaScript devs don't know about bitmasks.

I used them to speed up my sudoku generator.

I removed dark mode for the puzzle page. Couldn't make a color scheme that was as legible as light mode.
