中国真的是一个超级商业社会了。

最近中国政府发了那篇赴日旅游劝告,马上就有抖音主播看到了商机,直接飞日本,在大街上直播,渲染恐怖氛围。

“我真的是冒着生命危险和大家直播。”

“我在这里说中文都很害怕。”

“我已经回不去了,大家千万不要来,看我直播现场情况就好。”

搞得自己像战地记者一样,其实就是拍点街景,直播人气爆棚,打赏哗啦啦入账,晚上狠狠造和牛。

要不说中国卷呢,只要是有一点点赚钱机会的地方,恨不得钻进去一百个脑袋。

真正的资本主义。

12·3 불법계엄 1년…여성·소수자들은 그저 ‘응원군’이었나 www.khan.co.kr/article/2025... "A씨는 최근 전국장애인차별철폐연대 활동가들이 지하철 탑승 시위를 벌이다 폭력적으로 저지당하는 모습을 보면서 당시 광장에서 발언하던 ‘전장연 동지’들을 떠올렸다고 했다. A씨는 “윤석열은 탄핵되었지만 여전히 세상은 그들의 목소리를 듣지 않고 있는 것으로 보여서 매우 충격적이었다”고 말했다."

day 1.

Today I'll start with Ghost, the blogging platform! I've been using Ghost to power my blog for many years now.

I love the focused writing experience, it really helps me get in the zone by hiding anything I don't need. But it also has all the important features I do need just a click or two away.

There are loads of good free themes around, but it's not hard to build your own if you're familiar with web tech.

ghost.org

Thanks for the inspiration @neilNeil Brown

Jedna z šílených věcí na AI je podle všech indicií ta, že odpovídá zhruba dle toho, jak se dokáže sebeprezentovat tázající osoba v promptu.

Tohle jde proti všem principům revoluce domácích počítačů z 80tých let: počítače odpovídaly všem stejně, když se naučili jejich jazyk a měli příslušná přístupová práva. Sillicon valley byla kultura džín a triček, ne saka a kravaty.

V zásadě celá technologická kultura se zvolna mění na kulturu dress code - akorát jinak.

My hot(*) take is that teaching modular arithmetic before teaching things like ring homomorphisms and the universal property of quotients is kind of evil...

I think there are two kinds of people. The ones who think that there would be no way to motivate a quotient map of rings without an example like modular arithmetic. And then there are the ones who think that there would be no way to motivate and explain modular arithmetic without explaining what, precisely, it is doing in terms of universal properties (e.g. why some subtly different definition **must** be wrong).

I am both kinds of people, but if I must be honest, I am more the second kind of person. One important fact about comparing numbers "mod n" is that doing so forms a congruence for all the arithmetic operations. Students use this fact all the time, but they are using it ignorantly because they haven't been told that this is actually part of the definition, and they certainly haven't been equipped to deduce that it is OK from the weak intuitions we begrudgingly allow them to have.

(*) it's called a hot take for a reason!!

防衛省・文科省レクに行ったのですが「(子供向けの防衛白書が学校に配布され、仮想敵国として中国・ロシア・北朝鮮の地図が載ってる件について)これって外国籍の子どもになにかあったら誰が責任取るのですか?」という質問について
防衛省「自衛隊を広く知っていただくために作ったものですので(なんかあったところで責任とか知りません)」
文科省「あくまで各県の教育委員会が判断されて配布されたことですので」
私「じゃー県の教育委員会が責任を取るんですね?」
文科省「各県の教育委員会が判断されて配布されたことですので」

We (SCI Semiconductor) are about to hire some folks in the next couple of months (probably starting in January, since we're about to hit Christmas):

We're aiming to hire 1-3 FAEs, who can build out the open-source bits of the software stack (including drivers / various communication stacks), build demos, and work with customers on use-case bringup.

We also want to hire someone else on the toolchain side. Primarily + , but also working with our (and ) folks.

Let me know if you're interested!

EDIT: We are a full-remote company. It's easiest for us to hire people in the UK (and one of our investors would really like us to hire more people in Sheffield), but elsewhere is possible (though might, for tax purposes, require you to be officially a contractor for a while).

We're also going to be hiring people for our hardware verification and RTL teams soon (more on the verification side than design at the moment, I think). I'm not responsible for them, but I can find out more details if anyone is interested. Our first CHERIoT chip is nearly finished, we're starting to work on the second.

EDIT 2: Thanks to all of the people who have expressed interest (in public and private posts). I'll try to get back to you all next week!

EDIT 3: I hope I've replied to everyone now! If I missed you (there were more replies than I expected!) please let me know. I think we'll aim to do another hiring round over the summer next year, so if the current timeline doesn't work out for you, please still let me know and I'll keep you in mind next time!

Day 1 of Advent of Compiler Optimisations!

Why do compilers love `xor eax, eax` for zeroing registers? It's brilliant: saves bytes compared to `mov eax, 0`, AND x86 CPUs recognise this "zeroing idiom" early in the pipeline—breaking register dependencies and removing it from execution entirely. Even better: writing to `eax` zeroes the top 32 bits of `rax` for free, handling 64-bit longs in one instruction.
