I once dropped my phone like 40cm the 100th time and my screen went completely black. However, the touch still worked! After loads of time and comparing to another android phone, i managed to blindly navigate to that blind mode setting and enable it!

I have immense respect for those that are blind and need to interact this way. In the few days I used my phone this way I noticed multiple apps, especially my bank app with a keypad, had completely broken navigation and iirc not even numbered the actual buttons?! So it was a 'swipe right 9 times, double tap, swipe left 6 times' while the TTS was yelling nonsense!

I find this stuff super fascinating and been thinking about it myself. Maybe one could bootstrap tiny models on a rather 'pure' procedural data set. Neglecting [0] of course...

Super cool. Also, love reading high quality linux patches. I think many, myself previously included, are afraid to even read the kernel source as one thinks it must be super complex. Of course some parts really are. However, the code is honestly of such high quality. I also highly value that feeling of realizing something once thought 'arcane' was actually only made by other humans, and it is legal to go read it and learn from it.

Cool site, seems like a really useful tool!

New comment by logdahl in "Intuiting Pratt Parsing"

logdahl — Wed, 01 Apr 2026 10:58:26 +0000

Love Pratt parsing! Not a compiler guy, but I've spent way too many hours reflecting on parsing. I remember trying to get though the dragon book so many times and reading all about formal grammar etc. Until I landed on; recursive descent parsing + Pratt for expressions. Super simple technique, and for me is sufficient. I'm sure it doesn't cover all cases, but just for toy languages it feels like we can usually do everything with 2-token lookahead.

Not to step on anyone's toes, I just don't feel that formal grammar theory is that important in practice. :^)

logdahl — Sun, 22 Mar 2026 22:34:28 +0000

Of course :^) I'm close to jumping ship to GrapheneOS, but as a Swedish resident I really need our digital id services, digital mailbox, and banking apps. I have seen their page on app support, but I am slightly afraid its not up to date / will break any time. I guess the solution is to use one banking android phone and one GrapheneOS for everyday use.

Bit tangental, but if this was a real thing, we could hopefully stop letting google / microsoft determine whats spam. Private mail servers would hopefully more common and actually work. Super annoyed, I use cloudflare + protonmail for my custom domain, but I have the feeling that some outgoing emails from my domain gets blocked... 90% deliverability means practically useless.

Strictly speaking, Isn't there still a way to express at least one Illegal string in ArchivedString? I'm not sure how to hint to the Rust compiler which values are illegal, but if the inline length (at most 15 characers) is aliased to the pointer string length (assume little-endian), wouldnt {ptr: null, len: 16} and {inline_data: {0...}, len: 16} both technically be an illegal value?

I'm not saying this is better than your solution, just curious :^)

Super cool stuff! I love the idea of games being refurbished to the point that it can be kept, almost source original, and still played years down the line. For example, I love Another World for this, being just a bytecode blob where each port is just a VM (good writeup: https://fabiensanglard.net/another_world_polygons/index.html).

> it is nicer to write in those other languages

I think this is a matter of preference. Nowadays I cannot stand environments like Java (or especially Kotlin). "Tricky memory errors" is in my opinion nicer than a borrow-checker refusing sound code. I guess I really hate 'magic'...

Absolutely! I think this would likely be the next step.

Yeah, I use LODs already but as you say, even my lowest lod far away is too many vertices. Imposter rendering seems very interesting but also completely bonkers (viewing angle, lighting)!
