YES! For 3 years, while working on lunatic (github.com/lunatic-solu...), every day I wished reflections in Rust existed. Annotating every type that can be sent between processes was such a pain!

I can't believe we never got a sequel to this masterpiece!

It's been a pretty wild 12 months. I gave 4 different talks at 4 different conferences on 4 different continents. Thanks for having me, Rust community. I'm glad to be part of you.

Spending a few days on Skopelos. Mamma Mia! vibes.

Ok, this was way more controversial than I expected 😅

Over the last months I have been thinking about the productivity impact of using Rust. I have put some of my thoughts into a blog post. lubeno.dev/blog/rusts-p...

lubeno.dev got a cute new redesign!

Good thing then that I'm giving a talk in 4 days at Rust Forge on (among other things) making inference breakage no longer actually break things 😁

We have just pushed a big update to lubeno.dev If you are looking for a place to host your code with servers in the eu 🇪🇺, check us out!

"This tool is, today, the worst it will ever be." I wish there was a law that guaranteed that things only get better with time.

That feeling when you finally figure out the right Rust hack for a usecase that needs HKT...

#GitHub doesn't have good competition for individuals / small teams. Can't commit to Codeberg due to stance on private repos & commercial projects. GitLab seems as bloated and more expensive. Forgejo seems easy to self-host, but I'd rather not at this point. One of these days.

I have spent the day researching how React's <Suspense>, `useDeferredValue(<value>)` and `use(<promise>)` abstractions work together, and it finally clicked! You just need to think of it in terms of TWO exception system! Yes, TWO exception system built on UI tree structures. 🧵

I’m most concerned that it’s stuck. I think the Rust project has a real problem with things being designed, partially implemented, used in the compiler, and then never finished and stabilized for regular users outside of Nightly. IMO the desire for maximally generic APIs is part of that pattern.

Intel stock the second he tweeted.

One thing that doing creative work teaches you is that ideas are worth nothing. Anybody can have an idea. In a writers room you have to come up with a hundred ideas a day, and most of those don’t make the page. It’s the work of making something that gives it value. The patina of humanity.

First time I heard of the term "cognitive debt", but it immediately resonated with me.

📚 Whenever I see useCallback, I wonder: why do we need it here? And a lot of the times, when I look deeper, I see that it actually doesn’t do anything. I think a lot of code-bases would be better of just not memoizing at all - and then let the compiler do it for you:

Anyway just saying

wild how cargo is so good that cargo installing from source is often more convenient than getting the bin. rust is so nice.

The import takes some time, but big repositories are looking good!

Lately, agentic coding is giving me strong "how to build a business online" vibes. In the sense that most people that are talking about it are using agents to build tools for agentic coding. Step 1. sell a course online / use agent to improve your agentic workflow Step 2. ? Step 3. Profit

Still a lot of work left in determining the right branch color and sorting, but most of the rendering issues are resolved at this point. 🤘 You just get so much more insight into a repository by visualising it, like how active it is, who is working on what, etc. If anyone wants to try it lubeno.dev

If you are building a MVP, you can't just focus on the M. The VP is equally important.

AI knows what's up!

Scammers are now using calendly invitations to get in your inbox and calendar.

Next update is going to have some nice visuals

Today I learned!

Just did my first code review in lubeno.dev + WhatsApp. Can't wait to land the PR feature to replace WhatsApp.

The US is such a wild place. I could never imagine some politician in Europe posting this.

TIL you can declare extern functions as safe in modern Rust. extern "C" { safe fn i_am_totally_safe_i_promise(); }

I’m stuck in airplane reroute hell (current estimated time I get home: sometime after 2am 🥴), so I took a short break from the rebase hell I’m in at work and wrote a post about how I’m leaning on and tweaking jj to make the rebase hell less painful. v5.chriskrycho.com/notes/jj-tip...

We all follow dopamine loops. Get hooked on the right one.

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

We have come a long way!

Finished watching season 4 of The Bear, which means I'm back on this bullshit

Wait! What if we declared imports at the end of the file? 🤔

I'm so pumped for this! 😍 www.youtube.com/watch?v=m08T...

So predictable that we’ll see an explosion of digital products selling “ideas for million dollar businesses” that you can “just vibe code quickly”. Basically: “buy my digital product for $500, spend $1,500 on Lovable / Claude Code and become a millionaire.” Another hype train

"This patch thus defines a policy that the #QEMU project will currently not accept contributions where use of #AI code generators is either known, or suspected." github.com/qemu/qemu/co...

It feels like every company decided to pivot into the "agentic" development environment space. Just today I saw: warp 1.0 (terminal) -> warp 2.0 (ai coding agent) sst (framework) -> opencode (ai coding agent) And from what I can see, a few more are coming soon.

A very thoughtful post

Some ideas need time to grow on you!

Hope it can somehow be disabled. Text-heavy interfaces really don't mix well with transparency.

#jj-vcs 0.30.0 is out! github.com/jj-vcs/jj/re...

Looking at the prompts that were used to generate Cloudflare's OAuth Provider, working like this just looks exhausting to me. Instead of using precise tools to express your wishes, you are stuck in review hell during the whole process. Can't imagine working like that. github.com/cloudflare/w...

Back when I was finding my feet in tech everybody was buzzing about building positive change. Somewhere along the way, something changed. Fortunately for us though, tech is not the first industry forced to defend itself against dubious practices. What might we learn if we were to look elsewhere?

Why aren’t you pairing more with him? He types twice as fast as you. Of course he does. So does a cat having a seizure on a mechanical keyboard. But that doesn’t mean it should be writing production code. 😂 deplet.ing/the-copilot-...
