fellow music players: do you find yourself having very different mechanical skills seemingly at random? I'm having a good fingers day, and those are as surprising as the bad days I also have. It's strange; I don't think my software-making brain is like this

So there's a thing happening on open-source repos: people who are otherwise uninterested in your project but want to obtain clout will file mediocre PRs against your repo anyway. So: community tarpits? Create a legit-looking repo with a bunch of open issues, wait for PRs, blacklist those accounts

right, i mean, the process of aging is of every individual human becoming outmoded, so if you had been using your career to get out of remembering that, i can see how it would smack right in the face

My department is hiring tenure-track in computer science! Deadline: Oct 1, 2026. We care about and support both research and teaching. We're located in the suburbs of Philadelphia. It's a great place to work and live! I'm happy to answer any questions. www.haverford.edu/provost/news...

Netflix has now truly mastered the craft of "exactly as good as it needs to be to make the median Netflix focus grouper enjoy it"? _One_ reasonably famous actor, _one_ cross-cutting current society issue, and _one_ joke as risky as Churchill's Martinis have vermouth it's bleak

I happen to believe this, and it’s one of my lowest opinions of people writ large. I’m not proud to believe it, I take no pleasure in believing it, but I am front row to witness money move around in ways which accommodate this fact and I can’t deny it.

I am begging you to talk to other human beings directly, and not through a Claude layer. This goes doubly when I ask you, directly, to talk to me not through a Claude layer. Please.

Y’all should know @cderv.bsky.social has been on an absolute tear over at Quarto 1, while we work hard at Rust and collaborative writer work ahead of Quarto 2, quarto hub, and posit::conf I can’t avoid software engineering being weird in 2026, but I’m legit so proud of our work!

Quarto 1.10 shipped Friday. The highlights page lists one feature. The changelog lists 74. Mostly preview friction: stale pages, _brand.yml ignored until restart, format: changes needing two renders. If you work in Positron, that's your whole day. A boring release. Best kind.

(not a complaint here, but!) It is a pretty weird bsky thing that someone can quote-skeet you in a way that you cannot reply directly to them. I think this is the first I see it directly. (six digits if you're lucky. Often you're behind a code send to your email, and a code to read your email)

That’s all academia is, man. Just entering six digit codes faster than your colleagues down the hall until you get tenure. Impact factors and teaching evaluations were so 2009.

I just wound down my use of the Hey-dot-com email service over the white nationalist bulls**t of its proprietor, David Heinemeier Hansson (aka 'DHH'). Ditching a platform over flagrant racism: it shouldn't feel tough to do, even if it means disrupting one's precious social graph. I've done it twice!

A week-old post by Jake Lazaroff (@jakelazaroff.com), in which he quotes an older post of his. In the recent post, Lazaroff wrote:

"apparently DHH just published a blog post *verbatim* calling for remigration, so… shout out to everyone who responded to this crying about how mAyBe He DoEsNt AgReE with the speakers at the far right racism march he described as 'heartwarming' and 'powerful'"

In the older post, which links to a 2025 blog post titled 'DHH Is Way Worse Than I Thought,' Lazaroff wrote:

"show this to anyone else you know who also assumed DHH was just a normal conservative dude rather than a raging white supremacist lunatic"

And just from a dad’s perspective, it seems to me one of the explicit aims here is to make black girls feel like they are ugly. Like why else are you angry about a black little mermaid. And yes I take that shit personal.

No joke: what fraction of everyone's screen time is spend just refreshing logins? It has to be more than 10%, right? What complete embarrassment for the tech industry. Entirely seriously, this should be enough to get everyone laughed out of the room.

Ok so I was 45 and not 7 when I heard about this the first time lol. but this is genuinely cute, and no less because the “visual proof by induction” and the proof that (2^n)^2 - 1 = 0 (mod 3) are the same proof that you can work out easily in your head out on an evening walk

Text: “On some of those hikes, his father gave him math problems to solve. He still remembers one: You have a square grid divided into a certain number of cells. Prove that if you remove any one cell from the grid - it doesn't matter which — you can always
perfectly divide the rest of the grid into L-shaped pieces made from three cells each. The solution, which Deng figured out, required a concept known as induction, usually taught in high school. Deng was 7 years old.”
