@jdub TIL.
What’s the whole point of a “Following” feed if that’s going to be polluted with bullshit.
And it’s not even popular content I’d care about, but just garbage. 🤮

@copyconstruct “Following” has two modes, so now the dipshit’s site conveniently forgets our preference and keeps flipping back to “For you” AND “Popular”.

Code generation becoming super fast and cheap is going to spell the slow death of libraries.
Old, established ones (like Python requests or Rust tokio) will be still be around, but it’s unlikely to see new ones (unless super niche) establish themselves.
English
Sure, you can put processes in place to build more cohesive things across orgs, but that will lead to a bunch of people whining about “bureaucracy” and how Google moves slowly.
There’s no winning here.
Ultimately, having individual DRIs act as BDFL’s might be the only solution.
English
It’s a “people problem”, the oldest problem in the industry, not just a Google problem.
The cost of generating code going to zero *incentivizes* teams to unblock themselves ASAP, rather than dealing with the friction of coming up with cohesive, holistic, “cross-team” solutions.

there’s a new edition of @intensivedata which is one of the most pivotal technical books written in the last decade, and almost no chatter on this app about the new edition or the new content it covers.
Are there no serious engineers and practitioners on this app anymore? 😢
English
@zeeg Or for that matter, pioneering new open source projects that’s not some personal productivity tool.
Where’s the next generation of file systems, databases, orchestrators, device drivers etc? Vibecoders not interested in solving hard problems?
English
where's all those billion dollar businesses built from gas town and other slop farms?
oh
English
You know what’s more sobering?
Amazon *already* has some of the most stringent/sophisticated CI/CD game in the business. See x.com/copyconstruct/…
Most embracing “vibe coding” don’t have the guardrails Amazon already does and are going to relearn reliability first principles.

Amazon is holding a mandatory meeting about AI breaking its systems. The official framing is "part of normal business." The briefing note describes a trend of incidents with "high blast radius" caused by "Gen-AI assisted changes" for which "best practices and safeguards are not yet fully established." Translation to human language: we gave AI to engineers and things keep breaking? The response for now? Junior and mid-level engineers can no longer push AI-assisted code without a senior signing off. AWS spent 13 hours recovering after its own AI coding tool, asked to make some changes, decided instead to delete and recreate the environment (the software equivalent of fixing a leaky tap by knocking down the wall). Amazon called that an "extremely limited event" (the affected tool served customers in mainland China).

Soon, the entire software development and delivery stack is going to be owned by the two “core model” companies.
Everything from GitHub, to CI to CD to monitoring to debugging.
They’ll first start with the “development” stack, and then slowly move to the “delivery” stack.

New blog post, about a great little way to add fairness to distributed systems.
Combining stochastic fairness queuing, best-of-two, and shuffle sharding.

I've published the first two chapters of a new guide to Agentic Engineering Patterns - coding practices and patterns to help get the best results out of coding agents like Claude Code and OpenAI Codex simonwillison.net/2026/Feb/23/ag…

This app is now more slop than human generated content.
Which is a shame, because being able to connect with interesting people in tech was what made Twitter fun.
It’s only a matter of time before we’re going to see an alternative where only verified humans are allowed to post.
English
It’s kind of interesting that the “public face” of Claude Code are the creators and developers of the project, whereas for OpenAI/Codex, seemingly everyone at the company right up to the CEO is the hype person.
ngl, the first strategy seems more organic and authentic.
English
@threepointone IMO we all need to get much, much better at reading and digesting vast amounts of code, now that writing it has become automated and a commodity.
Code comprehension was always an important skill; but even more so now. Looking at large diffs and being able to zero in on specifics
English
@copyconstruct been talking about this internally, if devs are generating 2x more code (5x? 10x?) but humans still review every line, the bottleneck is going to frustrate everyone
small+stacked diffs might help, and we handwave "ai will do a first reiew pass" but it's not looking great
English
Unpopular opinion:
Unless you’re just prototyping, you should aim to understand as close to 100% of production code generated by LLMs.
Yes, all of it.
Effective mental models are still important for humans to sustainably maintain and evolve a codebase via prompting alone.

@Noahpinion this issue for the left is what “was the 2020 election stolen” is for the right.

To win elections, Democratic politicians have to lie and say Israel committed genocide

"Wiener caved—not because the facts changed but because he was presented with clear evidence that if he did not participate in the left’s Holocaust distortion, he would not win his election." commentary.org/seth-mandel/sc…
English
There are a small number of people who use LLMs to understand bugs better, go deeper into the subject matter, validate if the LLM provided solution makes sense, and generally improve their knowledge and expertise, but at an accelerated clip.
And many others who do none of this.
English
Tools like Claude Code are consistently better for things like analyzing server side Grafana dashboards and correlating it with logs, spindumps, client side sysdiagnose, TCP dumps, etc than it is just for codegen.
If you’re not debugging with these tools, you’re missing out.

@hkarthik We saw the same during the Arab Spring. “Free nations” bombed Libya and Syria, and everything went to shit. Led to a mass migration crisis which destabilized Europe
Sorry, best for “free nations” to stay out of this. Nothing ever good comes from intervention in the Middle East.
English
I am excited at the possibility of a free Iran. But it requires support from other free nations and democracies. Silently letting the current regime continue to suppress its citizens is not an option.
English
OSDI and SOSP are the two most prestigious systems engineering conferences.
Claude Code categorized a decades worth of papers into four buckets.
Directionally speaking, this looks about right. There’s less research happening in databases and compute than a decade ago.
