A few CPU hardware bugs

taricorp.net/2026/a-few-cpu-bu

«
Catherine (Whitequark)’s recent observations on poorly-engineered firmware reminded me of a few mistakes I’ve seen in vendors’ CPUs; some unimportant and others surprisingly bad. Since I’ve never seen these widely discussed, here’s some discussion and links to supporting evidence to make them more widely known, since I think they’re interesting.

기술 보자기

서역에선 태구랍(太具拉, Tech Wrap)이라 불리운다.
중원의 천세를 통일한 가위, 바위, 보자기의 완벽한 힘겨룸에 태평의 시대가 계속되자, 이를 시기하던 보자기파 서쪽 오랑캐들이 비밀리 개발해 낸 비기(秘技)이다.
기술 보자기의 등장으로 힘의 균형은 잠깐 무너졌지만, 얼마 지나지 않아 쾌도 핑킹(King)가위, 신속의 야바위가 등장하며 다시 천하 태평의 시대로 돌아갔다고 전해진다

It was my first full week back, so let's try Office Hours again this week.

📅 Friday, February 6th, 2026, 02:30 PM Central Time (US and Canada) time.is/0230PM_06_February_202

I will start some LLM + open-source work on my new project (possibly a new product) at 2 PM CT, in case anyone wants to join early.

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!

A photo of a white rectangular pcb with a lot of pinheaders extruding to all sides. To the left a USB receptacle sits on the board. A bunch of colourful cables leave the image to the right. The board says “analog-toolkit”

@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.
