This is a good filter for people who I don’t want to work with. Please understand how computers work. This isn’t even about understanding Docker. Any software person should know how the layers work at a high level and this is a VERYYYYY high level.

Isometric Toronto: Now with traffic. Simulated cars on Toronto's real road network, from the Gardiner to Bloor.

The whole downtown core of my isometric Toronto is drawn: Bathurst to the Don, Bloor to the harbour.
12.66 km² as one 256-megapixel image, about 2% of the city, made in one evening on my laptop.

All of us at Marvel Studios are deeply saddened by the passing of Sir Patrick Stewart. Sir Patrick brought Professor Charles Xavier to life with extraordinary grace, intelligence, and humanity, defining the character for generations of fans, from "X-Men" to "Logan" to "Avengers: Doomsday." He was a singular talent, a generous collaborator, and a true gentleman. Our hearts go out to his wife Sunny, his children, his friends, and the countless fans around the world whose lives he touched with his art.

Lex Fridman interviews a PHP security researcher
Lex: My guest today discovered a critical vulnerability in PHP. What is a vulnerability.
Researcher: A weakness that allows an attacker to compromise a system.
Lex: But aren't we all vulnerable.
Researcher: Yes, but
Lex: Is love a vulnerability.
Researcher: We're talking about remote code execution.
Lex: Could an attacker remotely execute love.
Researcher: No.
Lex: Stalin executed millions.
Researcher: What does that have to do with
Lex: Do you think Stalin was happy.
Researcher: I have absolutely no idea.
Lex: Fascinating. We're 3 hours in. Let's talk about consciousness.

🚨 Nightmare day for cybersecurity
Multiple major security incidents, active exploits, supply chain compromises...
If you run production systems, start patching NOW.
PHP: Two critical unauthenticated RCEs. Attackers already exploiting them. Patch NOW
LiteLLM: v1.107.0 on PyPI and Docker is BACKDOORED. Steals cloud, SSH, and AI credentials. Pin 1.106.2. Rotate secrets.
eMudhra: A certificate authority's keys were crackable. Update your browsers, systems, and trust stores.
Node.js / Next.js / React: Security releases for Brotli RCE, TLS bypasses, and TWO critical Next.js RCEs.
TiDB Cloud: PingCAP breached through stolen credentials. Customer information and other sensitive data exfiltrated. Read the attacker's release, fun stuff.
Plex2Shell: Weaponized within HOURS of the PoC. Attackers already deploying cryptominers and proxy backdoors.
BeyondTrust / Ivanti: Actively exploited zero-days added to CISA's KEV catalog. BeyondTrust attacks linked to a China-nexus campaign.
And that's not even the full list.
Patch. Audit. Rotate. NOW.
Beads, last of the Mutable Instruments modules, is now open source:
A gorgeous "granular synthesizer," processor and oscillator both. h/t @synthanatomy
Why this matters now:

West Coast, with penguins: Aaltoverb on Linux; Aalto 2 coming soon. @madronalabs with some very good news indeed; why it's cool:

Also, ThinkPads and fun Japanese ads featuring Donald Fagen to put you in a good mood.

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.

What the HECK is going on with tech?
In the last week: Multiple cloud outages, x DMs totally broken, antigravity doesn't work, my watch is showing me 15 year old cal events, mac OS is a mess, email is spammed to hell and every nerd on here is talking like new AI is the second coming
