A perllsp process (written in Rust, I think?) went rogue overnight and consumed about 500 GB of RAM, making my Mac very unhappy. (No time to debug it, so I uninstalled it.) Related

I wrote an opencode2 plugin so I can /connect @cursor_ai and chat with composer from the tui. not a wrapper around a hack. just the official sdk and a lot of "unsupported package" errors. 10/10 would debug again! Related

Engineering leader on Google Chrome; writes about web performance and, lately, about working with AI coding tools.
Their words
I would say, sometimes, I don't know if it's controversial, that very few developers understand memory management. And that makes it even harder to debug memory problems. And so the state of the art around memory debugging hasn't evolved all that much over the years.

Friendly tip for anyone vibe-coding a side project: instrument it. All of it — traces, metrics, logs, profiles. Send it to @grafana, hook up their MCP, and let the agent debug with real data instead of guessing. MCP Related

Their words
That was always the idea, and that that goes back even to the predecessor of Turbo Pascal, this idea that it's not just a compiler. It's an experience, right? I mean, you don't just compile your programs. You also edit them. You also run them. You also debug them. You also have a runtime library. It all has to like fit together.

When I built menugen ~1 year ago, I observed that the hardest part by far was not the code itself, it was the plethora of services you have to assemble like IKEA furniture to make it real, the DevOps: services, payments, auth, database, security, domain names, etc... I am really looking forward to a day where I could simply tell my agent: "build menugen" (referencing the post) and it would just work. The whole thing up to the deployed web page. The agent would have to browse a number of services, read the docs, get all the api keys, make everything work, debug it in dev, and deploy to prod. T… Quoting @patrickc When @karpathy built MenuGen (https://t.co/2OjrUJ3aLS), he said: "Vibe coding menugen was exhilarating and fun escapade as a local demo, but a bit of a painful slog as a deployed, real app. Building a modern app is a bit like assembling IKEA future. There are all these services, docs, API keys, con… Related

Had a session with very senior folks on how they build with AI and can’t help thinking there’s no better time to learn, clarify, brainstorm, write, debate, plan, design, code, debug, review, analyze, delegate, play, and in general do more more while doing less with AI—so psyched! Related

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
