From typescript beef, to a shared love for linux and tokens. The @dhh @theo bromance is the cutest in tech. Seriously, can you guys just set up a time to do a podcast together??
This is part of why people who try Omarchy on some old potato PC find that their new MacBook machine suddenly isn't very attractive in comparison. There are a lot of common developer tasks that are just way, way faster on Linux (it's the same with Docker!).

most teams have a spare mac doing nothing. it can now run 400+ sandboxes
1/ You already own a fleet of sandboxes. It's your Mac. We benchmarked Cua Spaces on a Mac Studio instead of a cloud box. A new Linux Space runs its first command in 235 ms. Then we kept adding Spaces until the Mac was full: 448 idle ones at once.

We doing brain surgery on the clankers boys
if you have a qwen3.5 4b around, please try steering neurons L14 N8949 +1 and L13 N7956 -1 now you have evil qwen recipe: dose × median(‖resid‖ leaving layer L, tokens 1:) / ‖W_down[:, n]‖` at the down_proj at every input

We will get a lot of awesome stuff like this going forward. Future is bright.
Have been working on various thing including a (hand crafted) engine for the past 7 months with the goal of large forests with highpoly vegetation (around 1M instances * 4M tris in this case). Haven't really been motivated to post on X lately, but I will go into more detail soon.

I’m shook OpenAI voice just got slapped hard I’m in complete disbelief that this new voice model is made by Block and not Elevenlabs et al. I mean Jack literally took it to 11 and solved the turing test for voice. you’ll never know if you’re talking to a machine or human.
We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence. block.xyz/dessa

We made the first AI model you can have a realistic conversation with that was trained entirely on speech! Dessa is a full-duplex speech-to-speech model that you can run on consumer GPUs. This is a GPT3 moment for speech.

Here's the new Claude experience on the iPhone Duo! It's going to be amazing for multitasking, Claude Code, and creating new things. Looking forward to see folk start using it tomorrow!

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.

The situation is getting worse every hour. AI agents are entering U.S. bank accounts, and banks are scrambling to shut them out. Axios reports that some appear to attempt actions beyond users instructions, raising fears over who is really in control.
SCOOP: Major U.S. banks are detecting unauthorized third-party AI agents inside customer accounts, including some attempting to take actions that appear to be independent of user instructions, sources told Axios. The findings have alarmed banking executives, who are racing to restrict access to their systems as AI moves at a velocity faster than financial institutions can respond, multiple industry and bank executives told Axios. Several banks are now preparing for worst-case and even “day after” scenarios, including how to rapidly secure or restore customer accounts if things go wrong, the people said. Several bank executives told Axios they're struggling to distinguish between human users and AI agents. One executive said banks also struggle to determine whether agents are authorized by customers or potentially operating without their permission, more akin to rogue agent behavior. Read my latest for Axios here: axios.com/2026/10/22/ai-agen…

if this PHP vulnerability allows remote code execution, doesn't that mean we can use the vulnerability to auto-patch all vulnerable servers?

Linux on the M6 Mac Mini, Day 5 - success! Omarchy is installed on the Mac Mini's hard drive. It boots, it runs. Still bringing up accessories, including Ethernet and GPU, so my work's not done, but 5 days from the macOS About screen to the Omarchy About screen isn't bad!

I think this is the future, no PRs, no code review, but also not yolo to main. The world has changed dramatically over the last year and I think what Thorsten lays out here is likely even more rigorous in reality than any strict PR/code review process from the dark ages (aka 2025)
No pull requests, no code review. We push to main. Our agents read production logs, watch deploys, grant feature flags, and check their own work end to end. Here's how we do that:

Many coding veterans are now starting to say this:
Intoxicating. I’ve been programming for 45 years, since so was 10. I’ve been a pro game coder for 33 years. Everything from hand coded assembly to UE 5.8. The paradigm shift to agentic coding is intoxicating. It is the biggest productivity jump I have ever experienced.
