今は1.5秒くらいプチフリみたいになるけど、頑張れば半分くらいにできる気がする。

組み込みLinuxも工夫すれば見た目を良くできるね。

Discovered a new method for detecting if someone is using Incognito in Chrome:

Write 512 tiny 1-byte responses into a scratch Cache API cache, then read:

https://t.co/gsVNLl57y6.estimate().usageDetails.caches

Normal Chrome: ~393kb
Incognito: ~85kb

Why? When you're in incognito, Chrome writes to memory instead of disk, which leaves less metadata residue

Valve co-founder Gabe Newell responded to accusations that Steam operates as a monopoly in the PC gaming market

Addressing the criticism, Newell said gamers have “plenty of options” when buying games.

According to him, players can choose from many digital stores, including rival platforms and stores run by game publishers themselves.

Valve says Steam’s success comes from a service that both gamers and developers willingly choose.

I've got an agent in a loop optimizing a renderer with the goal to minimize frame times (and tests to measure). It got times down from 88ms to 2ms and allocations down from ~150K to 500. Sounds good, right? Wrong. This is exactly why agent psychosis is a big fucking problem.

As an experiment, I rewrote the Ghostty core render state in Go, with access to identically laid out data structures as Ghostty and the exact same validation tests. I made a purposely naive renderer (simple, correct, but slow). 88ms per frame with 150,000 allocations (horrendous, lol)!

I then kickstarted a Ralph loop to bring the frame times down. I told it it can't modify input data structures or the public API or tests (they're correct), but it can do anything else it wants. It got to work.

It has worked for about 4 hours. I've spent around $350 on this experiment so far. The results?

88ms => 1.5ms
150K allocs => ~500 allocs

Incredible right? Nope.

My hand-written renderer I ported has frame times (same benchmark) of ~20us (0.020ms) and 0 allocations in the update path.

This is the problem with psychosis and lacking systems understanding. If you don't understand the system, you're going to accept that this is an incredible result. If you understand the system, you'll see better solutions immediately and can do roughly 75x better on throughput.

The people who blindly trust agent output are in the former camp. They're sheeple, overdrinking from a fountain of mediocrity.

Standard disclaimer: I use AI all the time. I like AI. The point I'm making is to not blindly accept results. Think. Analyze. Learn.

[Ed Zitron @edzitron]

Uber’s COO has said that it’s getting “harder to justify” its AI costs because there was no way to show a link between AI spend and any meaningful increase in useful features. This is the first time I’ve seen a company say this directly.

We keep hearing about 10x or 100x productivity gains in engineering and knowledge work.

But outside the model labs, I haven’t seen the corresponding 10-100x revenue growth across the market or increase in quality.

So where is the productivity going?

[John Carmack @ID_AA_Carmack]

It is a shame that the simple act of transferring a large block of data as fast as possible over the internet is not handled effectively by the primitive operating system calls. You either multiplex over parallel persistent TCP connections to combat head-of-line blocking and slow starts, or reinvent reliable delivery and flow control over UDP.

QUIC has a lot going for it, but it is a large library (six figure LoC!) and conflates security and performance in a way I don’t love. There is also fundamental information about competition with other processes and link layer congestion that should be useful, but is unavailable to user libraries.

You should be able to just write(really_big_buffer) and it is all taken care of for you.

I'm trying to figure out where to live next, and one big consideration is the climate. So naturally I made a tool that represents monthly average temperatures for cities as 3D rings so they can be compared more easily. Check it out: https://t.co/MqPb0ufLYY

The idea that everyone will just vibe code everything without any understanding of what’s happening, and it’ll all work out fine, is imbecilic. It’s a trade of quality for quantity, where quality was already low. All lose for anyone who wanted good computers.

The most correct take on AI coding agents I have seen. You may not like it, but this is the truth of the matter.

[htmx.org / CEO of Lil' Possum Philosophy (same) @htmx_org]

just posted a video for my students explaining why they *have* to write the sort of code that, yes, can be generated by an LLM

I am giving them this https://t.co/U61NTuAI2x file:

https://t.co/R6x5ChBHlw

and telling them "Look, here are the guard rails. I can't make you use the guardrails. If you want to be a good programmer though, use the guardrails."

I'm moving all my quizzes to in-person on-paper no digital devices, and that's what their grades will be mostly based on because there's simply no way to tell if a successful assignment was done by the student or an LLM.

adapt.

improvise.

re-adapt.
