That’s why the fundamental duality between compilers and LLMs is not about determinism.

For many practical reasons, LLMs are non-deterministic, but they could be 100% deterministic by returning the same inadequate answer every time a question is asked. And a compiler can be deterministic but full of bugs.

Compilers and LLMs are programs that expand/decompress compressed input.
Compilers deal with LOSSLESSLY-compressed forms of the final code while LLMs inputs are LOSSY versions of the final code.

@msnofficial_on No because that’s a terrible setting and a PM should know better than to approve it.

Do Macs not have an option to keep the device on even when the lid is closed?
It's been an option on windows for over 2 decades now

Unless you’re serving videos, CDNs are really cheap.

why does google serve google fonts for free? is it just for public good or is there a hidden incentive

Never call a module "utils" or "common". Go into debt if you have to.

Everybody who thinks ai is conscious has to do a mandatory from scratch transformer implementation. There are only floats and multiplications.

@gabor I do, but it feels like a fool’s errand in this day and age.

@ekzhang1 The late limiter for these tokens is based on electricity usage 😅

fun systems math: all of the world’s LLM API traffic (~100T tokens/day?) could be served on a single computer in your basement running Nginx
(assuming a token is ~4 bytes and you have 50G Ethernet lol)

@sqs I noticed Claude Code doing this one day and thought it was very clever (good!). It was weird that it asked for git stash permission right after all tests passed.
English
Useful technique in Amp with GPT-5.5 (deep mode) to make small independent commits from a big uncommitted changeset:
"git stash the uncommitted (including untracked) changes, then reapply this refactor that you performed on HEAD, then git stash pop and fix merge conflicts"

@slimjimmy The classical example is
parser generators vs hand-written parsers
Hand-written parsers are more work at first, but doesn’t constrain you when you need to deviate from the theory, do complex error recovery etc.
English
@slimjimmy Both right at the same time. It’s always hard to decide between highbrow algorithms and the lowbrow alternative: brute-force, slow but practical, often more legible (not always), flexible.

here's a bit of old lore for you - the creator of bittorrent telling linus directly git would not work
linus proved him wrong so hard the mfer went back to bittorrent and turned it into adware

No one has built a competitor to git because no one is as crazy as the man who built it.

@immortaldip @finbarrtimbers Silicon chips connected by high-speed buses… a distributed systems problem.

@finbarrtimbers wait, aren't we at stage that it's now silicon, power engineering problem ?

@dieworkwear It resembles the most common form of contemporary literature: chat groups.

Why do people write tweets like this?
Where every sentence gets a new line.
Sometimes a line might have two sentences. Like this one.
But generally speaking, every sentence has a new line, making a tweet look like a long block of text that no one reads.
Worse still, such tweets are often repetitive and winding, hammering on the same point over and over again.
The writing is often very bad.

If you didn't update any linux server you were using consider opensourcing all your data as this is actively being exploited, every linux is vulnerable. just prompt claude with this: "please update & security patch this system" "what about the kernel is it protected against “CVE-2026-31431” please protect "

The devil is in all the metadata: Linux capabilities, SELinux labels, BSD file flags, and pax arbitrary metadata keys… and so on.

tar is a surprisingly simple format (just the tar itself, without any compression). Implementing a parser or a generator for it (or at least a small subset of it) is a fun programming exercise. Really recommend.

The last 20 years of UI development have been a mess though.

TUIs are not good sorry yall a CLI is a utility, and situational. this should not be confused with stuffing a full interactive GUI into a low capability platform. "lets ignore all the great UI technology of the last 20 years and build some caveman shit"
