What is Hackers' Pub?

Hackers' Pub is a place for software engineers to share their knowledge and experience with each other. It's also an ActivityPub-enabled social network, so you can follow your favorite hackers in the fediverse and get their latest posts in your feed.

Yup. In the short term markets are about as rational as that bearded guy in a bathrobe shuffling around in his slippers under the freeway underpass shouting at imaginary greebles. Reminder: In the long run irrational stuff ends up getting washed out of markets as it gets out-competed, thus the "rational markets hypothesis". But in the long run we're all dead.

To spell this out clearly, the reason RAM has quadrupled in price
is that a huge quantity of RAM that hasn't been produced yet has
been bought with money that doesn't exist to populate GPUs
that also haven't been produced to go in datacenters that haven't
been built powered by infrastructure that may never exist to meet
a demand that doesn't exist at all to make profit margins that
mathematically can't exist while economists talk about this thing
they call the "rational markets hypothesis".

再次拜訪東台灣的書粥,看到改編喬治歐威爾小說《1984》的圖畫書,抱持著因很少買書,只逛獨立書店,所以只在獨立書店買喜歡的書的心情,就買了下去(荷包哭)。

目前翻了1/4,畫風很適合1984這本書,分鏡和圖像也非常有感,也再次覺得喬治歐威爾真的是洞察人性的劃時代作家,「真理部」在這個網路時代,實在是歷歷在目。

我覺得開始更想要探究這類題材,其實是電影《重裝任務》(2002)的世界看到的,克里斯汀•貝爾扮演的理性和感性的糾結,呼應了不少1984裡頭對思想控制的世界觀,而其電影的色彩風格,剛好跟這本圖畫書有種相近的感覺,很意外且有趣的巧合。

My old friend, a Raspberry Pi A+, has been running my home heating system for months, just like it did back in 2014.

It has not missed a single moment.
It has sailed through every so called cloud outage.
It kept working flawlessly even when the Internet connection was down, because it simply does not need it.

This is the kind of technology I love.
Of course, it runs NetBSD!

들리는 이야기로는 어차피 태반은 제대로 처리되지도 않고, 제대로 처리하는 곳에는 분쇄해버린 뒤에 바람으로 가벼운 라벨을 날려버린다고 한다. 무엇을 어떻게 가져가서 어떤 식으로 재활용할지, '분리수거' 30년에 걸쳐 기준이 운용된 적이 없는 것 같다 - 저마다 할 수 있는 선에서 적응할 뿐.

This is from the JSON-LD spec.

ActivityPub / ActivityStream are based on JSON-LD.

I think it was a very bad idea for JSON-LD to define "number" this way!

It makes it so numbers with fractional values are inexact & lossy.

This include values that are common for money.

For example, neither 0.10 and 0.20 can be represented exactly. So, 0.10 + 0.20 does NOT equal 0.30!

It should have used FIXED-point numbers rather than FLOATING-point.

number

In the JSON serialization, a number is similar to that used in most programming languages, except that the octal and hexadecimal formats are not used and that leading zeros are not allowed. In the internal representation, a number is equivalent to either a long or double, depending on if the number has a non-zero fractional part (see [WEBIDL]).

@film_girlChristina Warren “normal and fun” but you still expect people to get mad 🤔 (probably just cost of being on the internet I guess)

What’s the follow-up, TPing and egging the Canadian embassy? Maybe leave a lit bag of dog poo on their doorstep and doorbell ditch them?

I get trash talk, but it’s one of those things where both sides have to be in on the game, otherwise you’re kinda just insulting people and they don’t know why.

요즘 영국산 중 가장 좋다고 느끼는 것 스콘.
냉동실에 넣어두어 장기보관도 쉽고 해동도 실온에 두거나 에어 프라이어/오븐에 180도 정도로 6-8분 돌리면 한국인이 좋아하는 살짝 바삭한 식감이 살아난다.
그러니까 대표님 잼 수입은 언제입니까

洪民憙さんのこの記事、ブーストしてたが読んでなかった。

めちゃくちゃおもしろかった。 https://writings.hongminhee.org/2026/01/histomat-foss-llm/

ベンヤミンが、映画技術が少数の権力に寡占されていることに対して、市民による再領有を要求したことを思いだしながら読んだ(「複製技術時代の芸術」)。ベンヤミンが生きているころに、まだ技術の再領有は実践的にはかなり困難だったとおもう(というか方法論もなにもなかった)けど、いま同じ問題が実践的に解決可能な課題として問われているのだなと思う。

"問いはF/OSSコードに対するLLM訓練がある抽象的意味で倫理的かではない。どのような条件で倫理的かだ。答えはF/OSSがこれまで示してきた答えと同じだと信じる。我々が付与する自由が保存され伝達されるとき、改善がコモンズに戻るとき、知識が自由に留まるとき、倫理的なのだ。"

まさに「これが唯物史観だ」という文章。
