Twitter Archive: 2025
Twitter dot com was a microblogging and social networking service, where users could share short posts (commonly known as “tweets”) with text, images, and video.

Friends, I'm going to be announcing something very soon…would greatly appreciate your support in the form of RT/re-posts, etc. 🙏
In case you haven't read the latest edition of The Loop by @mold_time — you should, it's pure joy.

It's interesting how LLM-assisted programming makes writing skills much more important.
It's not just "it's better for your career", but actually impacts what you can build — or at least how quickly. twitter.com/thorstenball/s…

Huh, today I noticed that the WebGPU spec progressed to the "Candidate Recommendation" stage a few weeks ago. Seems like an important milestone!
I spent some time last year playing with WebGPU (via wgpu.rs); it's a relatively nice API and a lot of fun.

I didn't realize that:
• It's very widely supported
• The compression ratio is *much* better than PNG

Until recently I thought @posthog was just a cool company with a great brand and an actual (not cringe) sense of humour.
But I've been a customer for ~6 weeks and damn, it's a great product too.

And they just keep adding new features! I'll be turning both of these on ASAP.
There aren't many companies whose product updates I really *want* to see, but PostHog is def one of the them.

A frustrating thing about web dev is that new frameworks/tools never seem to reduce overall complexity.
2005: You need to know JS, HTML, CSS.
2025: You need to know JS, HTML, CSS, TypeScript, React, Tailwind, …
(Not to mention JS, HTML, and CSS are now much more complex!)

New blog post: Make it happen
It's an old story about a trip to LA, and a couple of spontaneous decisions that changed the course of my career.

Extreme Programming had some good ideas imo.
If (like me) you wondered what the origin of system cards (aka model cards) was…

I did some research into how various cloud providers are doing lighter weight isolation (i.e., not using containers) for server-side JS. Comments/corrections welcome!

t's kind of amazing how much detail you can find in HN comments from CEOs and principle engineers at these companies. Like this one between Kurt Mackey (Fly.io CEO) and Kenton Varda (TL of Cloudflare Workers).

"How Jane Street does code review" by @ianthehenry
→ janestreet.com/tech-talks/jan….
Not just about code review; imo it has some deeper ideas:
• explicitly modeling *what the user has seen* and using that in the UI
• subtle impl decisions (eg CR comments) can affect collaboration

@ianthehenry Interesting, looks like TigerBeetle is exploring a similar approach — doing code review via actual commits on the PR branch. twitter.com/jorandirkgreef…

Oooh, now here's a spicy take…JavaScript is not a "memory safe" language?

The Rule of 2 — pick no more than two of:
• untrustworthy inputs;
• unsafe implementation language; and
• high privilege.

Compiler/PL friends…roast me!
I'm working on one of the last chapters of @WasmGroundUp, "What Makes WebAssembly Safe?"
I'm hoping I can explain it in a way that's both approachable, and also…not totally incorrect from a PL perspective. Feedback on either is v much welcome!

Whoah, this kinda wild, didn't know this about the SPARC ISA.
"The instruction following the branch is executed before the branch takes effect."

On the topic of SPARC, I enjoyed this clip from @hasheddan's conversation with Robert Garner: twitter.com/MicroarchClub/…
I like this as a mildly subversive way to learn about assembly, debuggers, etc.
