12 months ago 100% of my coding was done locally against my computer's filesystem now ~5% is done locally, my computer is a conduit to download and upload files to cloud agents most days my iPad and iPhone are all I need and I'm getting 50x more work done than I was a year ago

this might be my last normal tweet before biotech goes vertical i'm not a whistleblower. I don't work at Lilly, Novo or any of the big labs but there is a massive shift happening in human biology right now. it's sitting in press releases and almost nobody reads them the last 6 months alone: - a once-daily pill roughly doubled median survival in metastatic pancreatic cancer (13.2 vs 6.6 months) - a one-time gene editing infusion cut hereditary angioedema attacks 87%, and 62% of patients stayed attack-free and off all other prevention for 6 months - a one-time gene edit for cholesterol dropped LDL up to 62%, and it held for over a year - a personalized mrna vaccine beat keytruda alone in a 1,137 patient melanoma phase 3 - retatrutide hit ~28% weight loss in a phase 3 - an ai-designed drug entered phase 3 - a pill that regrows hair passed its second phase 3 - an immunotherapy that could let some rectal cancer patients skip surgery, chemo and radiation just got fda approved - a man lived 271 days off dialysis on a pig kidney - human cells were caught passing chromosome-sized chunks of DNA to their neighbors, and it changes how the neighbors behave we are on the verge of an era where the human body is a software problem and the update cycle gets shorter everyday stick around, it's going to get weird bio/acc

ok update on the deleted repo thing, since it kind of blew up first, some context on why i posted it like that. there have been so many security incidents lately that my brain is basically stuck in alert mode. so when i saw a stranger in our audit log deleting a private repo, i assumed the worst. we figured out what happened. nobody hacked us, and it wasn't a github bug. that repo was a private fork of a repo owned by @StainlessAPI, the company that generated our SDKs. our entire SDK pipeline ran on it. Stainless got acquired by @AnthropicAI back in may. and on october 27, with zero heads-up to us, someone there deleted their copy of the repo. turns out when you delete a private repo on github, every private fork of it gets deleted too. same request, under two seconds. and our audit log shows the person who deleted *their* repo as the one who deleted *ours*. that's why it looked like a random outsider walked into our org and nuked something. no email. no "hey, we're cleaning these up, grab a copy." just gone, along with the production repo behind every one of our SDKs. github support walked us through all of it within a day, which, genuinely, thank you. one ask though @github: put this in the audit log. right now the event for our repo just says "repo.destroy" by an outside user. if it said "deleted because upstream fork parent X was deleted", we'd have understood it in two minutes instead of spending a night thinking we'd been breached. we had a local clone, so we pushed it back up as a standalone repo and the SDKs are running again. if you were a Stainless customer and you've got anything living as a private fork of one of their repos, go detach it today. it takes ten minutes. their delete is your delete.
someone outside our GitHub org deleted one of our private repos. no membership or invite or role. nothing in our org or enterprise audit logs gave them access. just one repo.destroy from the gh CLI. and it's not in deleted repositories, so no restore. @github how is this possible, what sorcery is this?

I continue to be humbled by @plugandplayjp’s support and generosity for ai&. There are a number of organizations in Japan that share our view of the importance around scaling intelligence via inference, and sovereign AI. plug and play is one of them! Thank you from @aiand_

確っっっ実に、これとローカルLMMを組み合わせて、専用のAIコンパニオンを生み出す勢力が現れる。 最近のAIによる3Dモデル生成力の上昇と、ローカルAIモデルの会話能力の上昇と相性が良すぎる。 無検閲AR AI コンパニオン…うーん。うん。

Code interviews are dead. Anthropic hiring manager: “I’m scanning resumes and portfolios for little prototypes that exhibit taste, empathy, and principled thinking.” MUST READ for anyone confused about how to get hired in the new era.
The coding interview is dead, at least for my team at Anthropic. I've seen enough to know that it no longer provides signal. I removed it from loops this month. I have a spicy, optimistic take - I think there's an opportunity for junior engineers: felixrieseberg.com/hunger-be…

Windows Copilot was so terrible it might very well have seeded the AI opposition we now see among normies. Useless functionality, hyped to the moon, and a dumb key on every keyboard that did nothing worthwhile. youtube.com/watch?v=erRVsllM…

At work (R&D at a fortune 500 company w/ 15k+ employees), every time a SaaS pitches their product, my first question in the review meeting is, "Why don't we just build this ourselves?" In the past, there were always good answers to that question. Today, I can't think of any. If we can point an agent at any website or demo, have it research the broader problem for 72 hours, build the product with a focus on our specific needs, with any extra features we want, AND save a million a year why would we pay for your SaaS? Scale? It only has to scale to 15,000 employees and a few million customers. We don't have the same scaling problem you do serving 1,000 businesses with 100s of million of customers. Scale is a non-issue. Reliability? Your 99.9% self-reported uptime is not impressive. We can pay to host an app on a hyperscaler too. And when we do it, we know with certainty whether the uptime number is true or not. Github's official status page reports ~99% uptime. The Missing GitHub Status Page reports 93%. Reliability is a non-issue. Bugs? You think your SaaS product doesn't have bugs to work out? I've seen bugs in third party products cost our company millions. Everyone is shipping early and often. Including your SaaS. Every piece of software has bugs. But there is a big difference between a bug in your code and a bug in ours. When the bug is in your code, we are at your mercy. Maybe you put it into Jira immediately. Are you going to bypass sprint planning? You won't have a fix for two weeks. Maybe you'll fail to reproduce and blame our code. Maybe it is our code. Maybe its an interplay. Since you don't have our code and we don't have your code, how are we going to figure that out? If it's all our code, an employee can fix it in an hour. If we need to, we can throw ten engineers with agents in a call until it's reproduced, the fix is merged, and it's validated. Bugs are a non-issue. Bandwidth? Agents are nearly autonomous now. They don't need to be babysat. I can spin up a project and let an agent run for 50 hours, have it build a PowerPoint and walk into a demo with leadership blind. If anything breaks, "I'm still working on that." Things always break in demos. Nobody cares. If leadership proposes a feature, the answer is, "Yeah, great idea, I can add that." Because I can. Bandwidth is a non-issue. Maintenance? We have so much prior art, inputs and outputs, we can benchmark anything. We have autonomous PR systems built on top of in-app feedback SDKs so even the non-dev users can contribute to every app or service. Even our analytics systems are tied to automated PRs. Maintenance is a non-issue. Support? It doesn't matter how much we're paying a month for your platinum level enterprise support when our point of contact has to fetch the one dev who already went home for every non-trivial incident. The incident is never trivial. We already checked the top 10 things it could be because that was faster than asking you. Support is a non-issue. Expertise? Agentic research. We can build anything. Expertise is a non-issue. Cost? The cost of intelligence has gone down 100x every year. You're still charging 2022 prices. You should be charging closer to your electricity costs. Cost is a non-issue. At this point, the only reason we don't switch off existing services is that transitioning 15,000 employees to something else is a pain in the butt. It would be a pain in the butt even with a perfect bug-free, infinitely scalable, perfectly-reliable clone. Your new SaaS doesn't have that moat. But it does give me an idea for a product to build.

Tokyo has a neat little calculator to determine how much you need to stockpile. You enter in general parameters about your family members, pets etc. & it produces a list of recommendations. Site is in both English and Japanese. bichiku.metro.tokyo.lg.jp/en…
