oh, and you can start using our product soon. the thing that anthropic build and won’t release? we built something similar, but you can use it, and it has all the bells and whistles you need.

very excited to see this out of A\ this is our thesis at @ersc.io! But we are building a git compatibility layer: ersc.io/blog/what-co... enterprise adoption of new source control is a big ask, so making a smooth bridge from the past to the future is a big part of our offer

Anthropic {bot}@anthropicai.xmirror.bot

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.

wild to see the replies to this post. i just had sol-5.6 write a fuzzer for incremental compilation in rustc almost autonomously. one of my cofounders had claude spend the night profiling/benchmarking our storage system and came back to a stack of changes in the following morning

This is the crux of the debate, right? Whether it's doing mimicry or reasoning. I struggle to see how you could view it as purely mimicry. It has to tie together multiple novel thoughts in a logical construction to create its responses.

we're ridiculously excited to have martin, and we're *also* super excited to unveil our new site!

annoyed by large build directories or cross-worktree artifact sprawl? a #jj-vcs megamerge is a great place to run your builds and tests, because because if the megamerge builds, so do all of your worktrees! plus, your build directories are O(1) with respect to worktrees, not O(worktrees)!

subtweet: rendering code efficiently in a browser is a nightmare and you will likely need some javascript to keep it performant. diffs.com is the best-in-class, open source library that does this.

if you want to be *really* snappy, you’ll need to give up the browser’s native search functionality. this is the cost of virtualization, which you’ll need in order to render only ~100 dom nodes at a time.

i think my take on the whole bun/zig situation is that people in leadership positions need to: 1. decide if they want to win or if they want to be right 2. shut the fuck up

if true, a real pot-meet-kettle situation

Huh, security concerns is...interesting. *MICROSOFT WAS IN TALKS TO LEASE ORACLE CLOUD CAPACITY: INSIDER *MICROSOFT WALKED AWAY FROM DEAL ON SECURITY CONCERNS: INSIDER *MICROSOFT, ORACLE DEAL COULD HAVE BEEN WORTH OVER $3B: INSIDER

hello everyone! we're hard at work on an imminent launch. we have scalable monorepo support, jj-first concepts (but deep git compatibility!) and stacked diffs. we're very flattered by the attention yesterday and today!

anyways, if you have precheck or precheck ankle monitor edition (clear) and have no checked luggage, i recommend arriving at the airport 20 minutes prior to boarding. it’s marvelous.

i don’t want to defend josh barrow, but he is right. i missed only one flight in my life two weeks ago, and united rebooked me on a flight 12 hours later at no charge

James Ball@jamesrball.com

He was right on this BTW. People get incredibly neurotic about missing flights because they've never missed one. Once it's happened to you (assuming you're not travelling with kids) it's annoying but fine and you start leaving/wasting less time at airports.

oh yeah, @ersc.io is an @antithesis.com customer! we’re horizontally scalable on the unit of a *repo* and we’re extremely serious about not losing your data.

austin 🇵🇸@stdlib.bsky.social

getting to use @antithesis.com right now and it's genuinely one of the most mind-blowing products i've ever seen. truly something special

big props to edd.ca.gov for being competent state bureaucracy! our payroll provider didn't file a form for a prior quarter, so I called EDD and an extremely component staffer helped me resolve the issue almost immediately.

in retrospect, it’s pretty obvious that a former ausa would be adept at fedposting

If leaders abuse the rule of law to make themselves immune to it, so that they can undermine the rights of others with impunity, by what moral or philosophical argument are they entitled to its protections, once they lose power? By what grace should they be sorted by law instead of by other means?

at @ersc.io, in addition to a traditional SaaS offering, we support bring-your-own-cloud deployments, so you can say [insulting jonah from veep voice] we're the cloud botherers

i think “get on board or get left behind” phrasing is ugly, but anthropic’s run rate went from 9 billion in december 2025 to 19 billion in march 2026. claude code has 40% margins. i rarely write code by hand these days, and there’s a ridiculous amount of low hanging fruit remaining in claude.

Eric Ravenscraft@lordravenscraft.bsky.social

just this week: -- OpenAI killed Sora -- Disney subsequently cancelled its investment in OpenAI -- Wikipedia is now banning LLM-generated content ...tell me again how this is all "inevitable" and you have to "get on board or get left behind"?

these models got scary good in last 5 months. i see no reason why improvements won’t keep coming, nor why would they wouldn’t get better in other fields.
