okay okay. you want mobile, we get it.
HERE IT IS: herdr for iphone, ipad and android.
see which agents need you, open the real terminal and answer. type, paste a screenshot, or just talk to it.
works with herdr-core. herdr tui isn't supported (yet)
more impressed to see Richard Brautigan mentioned
Two things I’ve been thinking about regarding AI:
• People often highlight the risks involved in AI, which are surely very real. I’m struck, however, by how hard it is to understand the contours of the positive scenario. There are easy-to-perceive and frequently invoked elements of a positive vision — more diseases cured, more material abundance, etc. — which sound great, but these are by themselves just ingredients. I’m curious what the larger equilibrium is supposed to look like. Do people work? If so, why? What is their marginal contribution? If not, how are resources allocated? What is scarce? What is the ratio between humans and AIs? Are humans in control, whatever that means? One sometimes hears the Culture novels invoked as one scenario, but I’m not sure they depict a desirable outcome. (AI runs everything and humans compete in games? Iain Banks himself said that the humans in the Culture are “somewhere between passengers, pets and parasites.”) There is Richard Brautigan’s famous poem, but do we want to be “returned to our mammal brothers and sisters”? (Isn’t that rewinding Genesis?) We could say that it was hard to imagine the world of 1900 from the vantage point of 1700, and that’s assuredly true. But nobody in 1700 was trying to recast humanity itself within a couple of years — things necessarily unfolded slowly and by increments, and therefore with the possibility for error correction. Given how rapid the rate of progress in AI may be, it feels strange for the upside case to be so opaque.
• There is increasing discussion of whether AIs are conscious or how we would know whether they are, with conclusions there often assumed to be relevant to matters of moral worth. At first blush, this seems a rather arcane, benign, or even absurd issue. (Remember the response to Blake Lemoine’s fears.) Setting aside the terms of the debate itself, or the relevant demarcation criteria, it seems to me a quite high-stakes question, for an affirmative answer — that is, granting moral worth to AIs — would presumably mean that the aggregate worth of AIs would soon outweigh that of humans in any utilitarian calculus. The AIs will be exceptionally wise and intelligent, and vastly more numerous (especially once one considers the imminent future and the AIs not yet born). As such, even epsilon of moral worth will multiply to a lot once one considers the quadrillions that could soon exist. (This is effectively a distributed version of the Nozick’s utility monster.) If this conclusion is unpalatable, I think one of three propositions needs to be rejected: the premise AIs can have moral worth; utilitarianism itself; or the belief that there is even a possibility that they will be far more numerous than humans.
With both of these matters (contours of future society; AI moral worth), there is the possibility of dramatic change. Today, people argue about datacenters. I’m curious how popular support for AI will evolve as more people come to understand these medium-term questions and the relevant stakes. What is the vision for AI that most people would be excited about?

Apple just put Xcode inside Claude Code.
It's an official Apple plugin, now in Claude Code's plugin directory:
• Build, run and test your app
• Render SwiftUI previews
• Drive simulators and real iPhones
• Read build logs and errors
• Search Apple's developer docs
Claude can now build your iPhone app, see what it looks like, and fix it without you opening Xcode.
Install in Claude Code:
/plugin install xcode@claude-plugins-official
Needs the latest Xcode on your Mac.

It’s really hard to explain, but all this is happening because of Knicks

I'm scrolling faster than you
I'm refreshing my feed quicker than you
I'm reading more bullshit polls than you could ever dream of pal
had our agents set this up for @runprimitive users today. super seamless and super easy to do
Users can now auto-connect plugins when they log in to Claude, with MCP servers that accept Claude as a trusted issuer.
If you’re building plugins for Claude, add support so users get started faster and stay connected without re-authorizing.

We got your back, New York!
Readers added context they thought people might want to know
Several figures here aren’t federal results or NY-specific. The $472B combines US wide pledges: Micron's $250B is nationwide (NY site $100B) Anthropic's $50B covers TX and NY. The 48% murder drop is from NY's state run GIVE program (28 departments, Jan – May 2026).

22歳の頃、すでに連載は三度打ち切りとなっていた。
担当編集者は「ラストチャンスだぞ」と励ましてくれて、そのつもりでネームを書き連載会議に提出し続けて一年ほどが経った。
その日会議の結果を待ち廊下に面した曇りガラスの向こうで過ごしていると会議終わりの編集者がぞろぞろと歩いてくる。
「森川ジョージという名前を見るだけで読む気なくなるよ」とハッキリと聞こえてきた。
残念そうにネームを返却する担当と会話を交わすことなくそのまま講談社別館に行き60ページを頭から書き直した。
先ほどの声が耳から離れない。
三度失敗したらそういう評価は当然だろうと思う。
ラストチャンスと奮い立たせてきたもののそれはもう使い果たしていたことを痛感した。
悔しさよりも悲しさが上回った。
憧れのあの人のいる雑誌から離れるという選択肢を迫られていることが悲しかった。
あの人の隣に並びたいのに自分にはあまりにも力が足りなかった。
もう記憶が曖昧だがおそらくこの時僕は泣いていた。
描いても描いても受け入れてもらえずついには会議でネームすら無視される。
連載を続けたかった。
漫画が上手くなりたかった。
でもあまりにも力が足りない。
どうしていいかわからない。
ずっと頭の中であの人に問いかけていた。
『漫画上手いって一体どんな気持ちですか?』
『漫画上手いって…』
答えてくれる人はいないけれどずっと問いかけた。
もはや考えているのはネームではなくそれだけ。
考えられないからそれをそのまま書いた。
『強いって一体どんな気持ちですか?』
もう何も出てこない。
これでダメなら漫画家をやめよう。
そう決心してネームを再提出した。
そして連載が決定した。
「はじめの一歩」はあの人へ問いかけで始まって、今も問いかけながら続けている。
いつか実際に聞いてみたかったが少し仲良くなってしまって照れくさくて口に出せなかった。
機会はたくさんあったのに。
はじめの一歩は僕の漫画家としての第一歩であり、あの人との悠久の会話の始まりだった。
もう答えてくれる人はいないけれど、これからもずっと問いかけていく。
『ちばさん、漫画上手いって一体どんな気持ちですか?』
ありがとうございました。
Claude Code on Desktop -> our custom AI VM's as ssh environments -> Opus 5.5 + pstack. Connect to the @runprimitive MCP server + Kube.
this shit is literally the best. I literally don't even need herdr anymore. terminal, browsers, file explorer, docs, all in the desktop app.

Ghostty 1.4 is now out! Full Kitty graphics with animation (the first terminal besides Kitty to do it), scrollback compression for much lower memory usage, macOS 27 support, a new OpenGL renderer on Linux, ghostty +ssh, big performance gains, and hundreds more changes.
The highlights:
- Scrollback compression: scrollback compresses ~90+% on average, meaning your terminals use that much less live memory
- Huge memory savings across the board: no single large thing, just lots of good improvements lowers memory usage everywhere, netting anywhere from 50 to 90% less memory usage depending on workload
- Kitty graphics is now 100% complete, including animation and relative placements, after a full conformance pass against the spec and Kitty itself
- The Kitty clipboard protocol, with an image preview when a program asks to read your clipboard
- Split drag and drop on Linux, including between windows
- ghostty +ssh installs terminfo on remote hosts automatically, so things just work over SSH
- Lots of terminal emulation accuracy fixes
This release is 7 months of work from 172 contributors over 2,889 commits. It also fixes 10 security advisories, so please update.

トムと写真家の大橋仁くんには「ヴィム・ヴェンダース1987年映画『ベルリン・天使の歌』でブルーノ・ガンツが演じたミドルエイジの天使という設定でお願いしたい」と伝えました。
アルバム『キッドA』の最後に収録されている“Motion Picture Soundtrack”の、レコードになる時にはオミットされてしまった最後のヴァースの歌詞からの連想です。
撮影場所については当時のごく平均的な日本のオフィスをイメージしていたので、レディオヘッドが所属していたレコード会社のディレクターに相談して、彼らと取引のある関連会社に頼み込んで実現しました💦
今だと絶対に撮れないですよね💦

Today, @NYCCouncil passed Romanch’s Law, ending horse carriages in NYC by June 2028.
When Central Park was created in 1858, NYC had roughly 800,000 residents, and carriages were part of daily life. Now, the Park sees 40M visits a year, and carriages pose a serious safety risk.
