RE: mstdn.games/@britt/11601309470

So, I helped Britt out with moving her instance to a new server provider this week.

While the people at toot.io were relatively helpful in our email chain (once she was finally able to get a hold of them in the first place anyways), the setup at toot.io was a bit strange and not optimized for an instance of her size. The actual server itself was well *over*powered for her to be seeing the slowdowns she was, and Mastodon & especially Postgres just weren’t using those resources to a full extent.

Honestly the biggest red flag 🚩🚩🚩 to me isn’t what toot.io is doing now necessarily, but that it was apparently sold(?) to completely new management without notice to customers. In a niche service industry like this, that seems like a big problem to me, to not even explain who’s taking over and why you should trust them.

The previous ownership is probably more at fault for this relatively speaking, but it’s probably a good opportunity for toot.io customers to reevaluate their hosting options… Even if you ultimately end up sticking with toot.io, you simply might not be fully aware of what’s going on over at your own hosting company anymore, and that’s always worth double-checking 👀

I'm supposed to be working, but something's getting in the way. Something too fluffy and adorable to move

I should be writing the 2nd book in our Underspace series (book 1 is available now - about a girl who finds the doorway to another world on the roof of her school - you might like it!)

But I think I have to stay here and pay attention to Molly. She's being highly persuasive (pic for evidence). I don't think I can talk my way out of this one...

A black & white cat is lying between my legs as I take the picture. She is rolled on her side, with one paw over my left leg, as though holding me down and preventing me from leaving. Her head is tilted upwards and she is looking at the camera

I finally got to reading PKD's "Ubik" this week. I think I bought the paperback like 10 years ago, but I never read it, because I hated the print quality. :D I really hate it when the text in a book is not looking crisp and sharp, but I'm a weird person I guess.

Anyways, I'm happy to report that this was probably my favorite PKD book I've read to date. What's your favorite?

I'm looking for a C compiler that:

- is simpler and smaller than TinyCC
- is capable of compiling TinyCC
- is written in *very* simple C or a language simpler than C
- can plausibly support risc-v (I can add codegen myself, just can't have deeply hardcoded x86 assumptions)
- has a FOSS license
- is not GNU Mes

Does anything matching these criteria exist?

I should do a production run of my analog-toolkit, my small STM32G431 dev-board. It comes in handy again and again, I have broken out most useful peripherals, USB, PD, UART, I2C, HRTIM, TIMs, Op-Amps, Comperators, the DAC and of course a bunch of ADCs (with on board capacitor, pull-up, pull-down and biasing options).

I just recently used its ADC and comperator in parallel to measure the time between two tigger events. The ADC was reading the averaged analog rail on which the trigger event occurred, setting an internal DAC to the negative comperator pin, with the the analog rail going to the positive comperator pin. The comperator was then set to start and stop a timer. Basically an automatic trigger voltage was measured and set via the adc, while high speed trigger events triggered the comperator, handy!

Assembling a few this evening by hand, a friend asked me for one. I should really have a few assembled, giving them out to friends, like with the OtterPills!

@hongminhee洪 民憙 (Hong Minhee) :nonbinary: I wasn’t able to join you talk on Tuesday but the slides inspired me to finally try @fedifyFedify: ActivityPub server framework 🙌
What a cool library thank you so much for building it. It was amazingly easy to get going.

Got inspired by @liaizonwakest ⁂’s posts about groups earlier this week:
groups.louismerl.in/groups/test

Source code incoming.

せんきょ

「今回ばかりは」って声を結構見るんだけど、それ毎回言ってる気がする(毎回言ってないと本当にそうなってしまうのだが)
こういう人達が「今回は周りの声も強い」とも言っている
自分には分からない、毎回こんなものではないのだろうか
自分が無茶苦茶左に偏っているから全体を見渡せてない可能性大

The fact that the President of the United States posts a racist video with an image depicting the Obamas as apes and we’re supposed to pretend it’s perfectly normal, everyday stuff shows exactly what is terribly wrong with today’s political mainstream media.

It's FOSS cites facist lunatic

RE: mastodon.social/@itsfoss/11601

Linux users: haha funny, they put a bash manual in the files

Me: It's time to boycott It's FOSS and shame the author Abhishek Prakash for citing the Lunatic Journal. Unbelievable this made it past a review process for them to cite conspiracy theorists.

블친분들이 종종 저의 나이와 성별을 궁금해하셔서 이 트윗으로 한번에 말씀 드립니다. 17살. 남자이고요. 평소에 반 여자아이들에게 <소드아트온라인> 의 주인공인 키리토와 닮았다는 이야기를 많이 듣습니다. (제가 말만 걸면 여자들이 뺨을 붉히더군요)

AI 붐 때문에 명확해진게 인류의 에너지와 자원은 굉장히 제한적이고 몇몇 나라에 몰려있으며 반도체도 필요한 그 시점에 충분히 찍을 수가 없음. 스마트폰, 컴퓨터 다 마찬가지란 이야기. 대만, 한국에 전쟁나면 인류는 일정 수준 이상의 컴퓨터를 만드는게 불가능해진다. AI 만능, 기술 만능 이전에 그냥 전세계가 피보는거야. 전쟁나면 KRW보다 비트코인이 안전할 것 같아요?

Apparently AMD's AutoUpdate downloads the updates over HTTP and executes them without any validation (presumably as SYSTEM user). AMD was notified of the vulnerability but according to them "attack requiring physical access to victim's computer/device, man in the middle or compromised user accounts" are out of scope.

Madness.

Just for fun, I tried signing up for litessl.cn/, the free Chinese ACME CA (powered by TrustAsia), using the browser translator.

After going through 4-5 captchas, one of which was unsolvable, they want to verify my phone number.

Dunno if it works if you're not Chinese, and I'm not sure I want my identity in a government cryptography database (too late), so I guess I'll give up.

Being on Team Words Mean Things is difficult these days, particularly when multibillion-dollar companies put out breathless press releases saying "By using our massive language model, whose training data includes every version of GCC ever released, and having it autocorrect its own output by testing it against GCC, we managed to make a C compiler that mostly works for only $20,000 in a week and gosh I have so many feelings."

I mean, what the fuck are we even doing here.

The fix was to use GCC as an online known-good compiler oracle to compare against. I wrote a new test harness that randomly compiled most of the kernel using GCC, and only the remaining files with Claude's C Compiler. If the kernel worked, then the problem wasn’t in Claude’s subset of the files. If it broke, then it could further refine by re-compiling some of these files with GCC. This let each agent work in parallel, fixing different bugs in different files, until Claude's compiler could eventually compile all files. (After this worked, it was still necessary to apply delta debugging techniques to find pairs of files that failed together but worked independently.)

the first bandcamp friday of 2026 is here 💗 back in december, i released my latest slab, weaving unreleased songs & feelings through a number of electroacoustic tools into an ambient tapestry of introspective yearning. everything left unsaid remains within me
