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.

Excalidraw CLI v0.3 released 🚀
- Render to SVG
- Markdown conversion
- Export frames as separate images
- Share as link/slides (Excalidraw+)
- Many small fixes
The response to @sailmode has been overwhelming. My inbox exploded with requests and amazing feedback.
Honestly, I love working with Sailmode, even on the smaller cover display. The next build is so much better and lands in TestFlight within a few hours.

libghostty 1.0 is here! I started Ghostty ~5yrs ago to work towards this. Today, libghostty is in hundreds of projects used by tens of millions of people. 1.0 marks ABI stability, quality, and an invite for distros to begin packaging. mitchellh.com/writing/libgho…
Since starting the Ghostty project in 2022, the most common question I've been asked is "why?". Today, I'll answer this by showing the broad industry impact libghostty has already had.
On top of JetBrains and Neovim already mentioned (that alone being over 10 million users):
-KDE developers are experimenting with a Konsole replacement built on it.
- Vercel's Turborepo uses it to render task output in its TUI.
- devenv uses it to drive shells.
- Antithesis used it to fuzz TUI programs and found real bugs in btop and others.
-Ghostel brings it to Emacs.
- ghostty-web is the WASM build with an Xterm.js-compatible API.
- Commercial products like OrbStack embed it.
- And a whole wave of new terminals and "agentic" coding tools, such as herdr and cmux, have been built on it rather than writing yet another emulator.
There are community bindings for Rust, Go, JavaScript, Swift, Python, .NET, Elixir, Dart, Java, and more, and the awesome-libghostty list tracks well over a hundred projects.
More people today use a terminal powered by libghostty than use Ghostty the application, by a very large multiple. And libghostty is having a much larger impact than being "just" a terminal emulator.
I'm excited to see where people take it from here.

Drag-and-drop makes the digital graspable, but building it well is fiddly enough that many don’t bother. Declarative Dragging (with Josh Horowitz & Jeff Heer, #uist2026 best paper award), lets you make an element draggable just by listing the states dragging it can reach.
Language models can do a lot, but they're only a small part of what machine learning can do.
Today we're introducing two new Swift packages for speech and decisions, with open models from 🤗 Hub that run on device:

*ehm ehm* BIG ANNOUNCEMENTS DAY 📣
two new things cooking in herdr labs 🐏🧪
a brand new herdr-core, and a desktop app built on it. open source.
first, the app: software that fits you. every part of it is a file your agent can change. you just ask.

We've decided to sunset Arc on December 22, 2026.
That's not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way: we have so much pride and love for what we made alongside the Arc community.
Our priority is to deliver best-in-class security for our members. Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. Dia was built from the ground up to meet today’s security standards, so that's where our engineering and security teams will focus moving forward.
We've worked to make switching to @diabrowser as easy as possible for Arc members. Here's how:
· Your passwords, bookmarks, extensions and history come over to Dia seamlessly.
· Spaces, Folders, and Tab Groups are in Dia and import over with your data intact.
· Dia now surpasses Arc benchmarks in stability, speed, and security.
· The browser features you use in Arc are free in Dia, and the AI is optional.
Thank you for using Arc, for pushing us to make it better, and for building alongside us. The team that made Arc is the same team behind Dia, and some of our most ambitious work is just ahead. We'd love for you to be there with us when it lands.
here's how i shipped 2,500 PRs last month to production
this was originally supposed to be for Cursor Compile in London. i couldn't make it since i was livestreaming for Grok @Bot Galaxy so i'm making it available for free here on X! watch it on 2x speed, i talk slowly

Interesting
New on our Engineering blog: Creating in-house source control.
In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale.
Here, we share how we built a new version control system—and fully migrated our monorepo from git—in five months: anthropic.com/engineering/re…

Dusting off this tweet from April because this gap in shared understanding of LLM capability is *widening*. It's now less "two groups of people speaking past each other" and more a sharp funnel.
- Napkin math somewhere around 6B people (~75% of the population) have barely come in contact with LLMs at all.
- Around 1-2B (~20%) are casual and infrequent users of free-tier ChatGPT-like products. This group sees derpy chatbots and treats them a bit like a better Google search, a writing aid, or etc. Maybe an agent tries to book you a flight. I have non-tech friends who (reasonably, imo) say they have not much use for it at all. Even many professionals outside of math&code are in this tier. For example, execs and many other functions spend a lot of their time talking to other people, so while they understand what is happening intellectually, it is still second-hand and a bit abstract.
- Now we get to professional use of frontier-grade LLMs in math&code. Somewhere around 20M people (0.2%) see first-hand that large, complex projects that used to take them weeks/months can now be completed by agents with a prompt. Building apps, copying apps, translating apps, decompiling apps from binaries... This has all happened very quickly and recently - less than 1 year ago, I was writing code manually by hand, typing memorized computer code commands into a code editor character by character, occasionally pressing Tab to autocomplete a little chunk of code.
- And finally we get to the ~5,000 people (~0.00006%) with access to frontier-grade systems internally. The external world has seen the preview. It looks like swarms of thousands of agents collaborating over weeks on software mega projects: minting zero days, running cyber attacks and defenses at machine speeds, discovering new science, advancing the frontier of mathematics. Things that would have taken top professionals in the industry years of work. Meanwhile, human review and comprehension are starting to fall behind. For example, people are still involved in the "archeology" of the OpenAI-HF incident from many months ago. Mathematicians may be poring over the 722 manuscripts on frontier mathematics for a while.
The funnel is driven by a combination of factors:
1. The impact scales with ambition, problem size, and horizon. A question with a paragraph answer barely stresses the system. You need a reservoir of big, difficult problems that you really care about. This aspect drives the consumer / professional dimension of the funnel.
2. The jaggedness of the system (which I have written about a lot separately). Capability peaks in domains that are digital, verifiable and economically valuable. This is because LLM capability emerges from reinforcement learning on verifiable rewards on a curated environment mixture driven by revenue potential. This aspect primarily drives the area (e.g. math&code) dimension of the funnel.
3. Access. Free-tier, paid-tier, internal.
So this is the weirdness of the moment. The general public has mostly not interacted with these systems. When they have, it looks like a derpy chatbot. The majority of professionals still see only a modest uplift. And a small sliver of professionals are experiencing the vertigo of the curve going vertical. And it is all happening at the same time.
Judging by my tl there is a growing gap in understanding of AI capability.
The first issue I think is around recency and tier of use. I think a lot of people tried the free tier of ChatGPT somewhere last year and allowed it to inform their views on AI a little too much. This is a group of reactions laughing at various quirks of the models, hallucinations, etc. Yes I also saw the viral videos of OpenAI's Advanced Voice mode fumbling simple queries like "should I drive or walk to the carwash". The thing is that these free and old/deprecated models don't reflect the capability in the latest round of state of the art agentic models of this year, especially OpenAI Codex and Claude Code.
But that brings me to the second issue. Even if people paid $200/month to use the state of the art models, a lot of the capabilities are relatively "peaky" in highly technical areas. Typical queries around search, writing, advice, etc. are *not* the domain that has made the most noticeable and dramatic strides in capability. Partly, this is due to the technical details of reinforcement learning and its use of verifiable rewards. But partly, it's also because these use cases are not sufficiently prioritized by the companies in their hillclimbing because they don't lead to as much $$$ value. The goldmines are elsewhere, and the focus comes along.
So that brings me to the second group of people, who *both* 1) pay for and use the state of the art frontier agentic models (OpenAI Codex / Claude Code) and 2) do so professionally in technical domains like programming, math and research. This group of people is subject to the highest amount of "AI Psychosis" because the recent improvements in these domains as of this year have been nothing short of staggering. When you hand a computer terminal to one of these models, you can now watch them melt programming problems that you'd normally expect to take days/weeks of work. It's this second group of people that assigns a much greater gravity to the capabilities, their slope, and various cyber-related repercussions.
TLDR the people in these two groups are speaking past each other. It really is simultaneously the case that OpenAI's free and I think slightly orphaned (?) "Advanced Voice Mode" will fumble the dumbest questions in your Instagram's reels and *at the same time*, OpenAI's highest-tier and paid Codex model will go off for 1 hour to coherently restructure an entire code base, or find and exploit vulnerabilities in computer systems. This part really works and has made dramatic strides because 2 properties: 1) these domains offer explicit reward functions that are verifiable meaning they are easily amenable to reinforcement learning training (e.g. unit tests passed yes or no, in contrast to writing, which is much harder to explicitly judge), but also 2) they are a lot more valuable in b2b settings, meaning that the biggest fraction of the team is focused on improving them. So here we are.

我最近在開發一個自己用的 Mac app,算是實驗吧,讓滑鼠游標可以自動切換到我正在看的那個螢幕上。女朋友對這個 app 的評語是:荒謬 XDDD
我會想做這個 app 是因為有外接螢幕的情況下,叫出 Alfred 時它常常不會出現在那個我正在看的螢幕上,這種感覺有點像 USB Type-A 要用時總是插反 XDDD
Alfred 的視窗可以設定成根據游標所在螢幕位置顯示,我想到的方法是讓 Mac 知道我在看哪個螢幕,並且把滑鼠游標移過去。
要做到我想要的效果,假如不另外買 eye tracker 儀器跟軟體,另一個選擇是一般視訊鏡頭搭配 Beam Eye Tracker,測試效果還不錯,真的可以把游標移動到你正在看的螢幕上。
可惜我試用的版本雖然支援外接螢幕,卻不支援 Sidecar,也就是 macOS 讓 iPad 當外接螢幕的功能。Mac 版也還在 beta,而且是 Intel 架構;而 macOS 28 之後,Rosetta 將不再支援一般 Intel app。
所以跟 AI 討論一番之後就決定開工,透過 MacBook Air 內建的 FaceTime 攝影機,判斷我目前正在看哪一個螢幕,並且在偵測到視線轉移時,自動將滑鼠游標移到對應的螢幕。
跟 Beam Eye Tracker 這類軟體不一樣,我不需要精確計算出眼睛正在看螢幕上的哪個位置,只要能判斷我正在看哪個螢幕就行了。此外,要讓游標移動是合理的,還得知道它原本在哪裡,以及我的視線是不是正在切換螢幕。
目前的做法是透過攝影機取得影像,利用 Apple Vision 偵測臉部、眼睛、瞳孔等特徵,以及頭部姿態,再搭配 MobileGaze 這個機器學習模型,分析臉部影像、估計視線方向。接著,讓三個用我個人校正資料訓練的分類器,分別根據頭部姿態、眼睛特徵和 MobileGaze 的估計,判斷我正在看哪個螢幕,再綜合三者的預測結果。
不過,光是知道我正在看哪個螢幕還不夠,否則游標可能會因為短暫的誤判而跳來跳去。所以 app 還得確認我的視線原本是在游標所在的螢幕上,然後真的轉移到另一個螢幕,而且有持續一小段時間,才會真的移動游標。
移動時也不是把游標放到我正在看的位置,而是回到游標上一次在該螢幕的位置;如果沒有紀錄,就移到螢幕中央。如果我正在打字或手動移動游標,app 就會暫停讓游標跟著視線移動,避免跟我搶控制權。
目前正在測試日常使用,成功率體感上有個七、八成了。我也在測試搭配 AutoRaise 使用,它能夠在你移動游標後,自動將游標底下的 app 拉到前景。我想知道這樣搭配使用的體驗如何。
每次回到座位看著螢幕,滑鼠游標就會自己出現,感覺真神奇。

I am surprised that people are surprised this is how I prompt Claude.
Talk to Claude the way you would a coworker. There's no secret to prompting. There's no need to be overly scaffolded or prescriptive for most tasks -- give Claude a goal, and it will figure it out.
Back in the Sonnet 3.5 days, your prompt mattered a lot. Nowadays, it's much more important to communicate to the model:
1. What you want it to do
2. How much effort you want it to spend
3. How it should verify that it did the right thing
