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.

h12o's Advent Calendar 2025 15日目

クリスマスで降誕を祝われるイエスは羊にたとえられるが、Mastodonになぜか羊が多いのはたぶんまったく関係がないはず。

ところでこれは、新橋で見た、Mastodonにいそうな羊。

"In the last 100 years, Russia has attacked at least 19 countries - some as many as three or four times.
None of those countries has ever attacked Russia.
So (Russia) doesn't need security guarantees.
The Security guarantees are needed for everybody else."
- Kaja Kallas, Fmr. PM of Estonia

This chart shows all objects in the Universe, arranged by mass (vertical) and radius (horizontal).

The edge of the upper left corner is the "Schwarzschild radius" - anything along this edge becomes a black hole, so we don't expect stuff above and to the left of that.

The edge of the lower left corner is the "Compton wavelength" - anything here has a size so small that measuring its position that accurately would require enough energy to create a new one.

These two corners intersect in a white dot. This would be a black hole so small that it's heavily affected by quantum mechanics. By definition its mass would be the Planck mass, and its radius the Planck length. Nobody has seen such a thing.

The black region to the left of that dot, labeled "QG", contains imaginary objects that are more compressed than black holes, yet also ruled out by the uncertainty principle. So they're doubly impossible - unless Quantum Gravity, which we don't understand, changes the rules.

The pink strips of slope 3 are lines of constant density. For example "QGP" is the density of quark-gluon plasma, "BBN" is the density of the universe when Big Bang nucleosynthesis was going on, and so on.

The Earth is only slightly more dense than a flea.

The black dot labeled "Hubble radius" is the whole observable universe.

I like this chart a lot. It's from here:

C. H. Lineweaver and V. M. Patel, “All objects and some questions”, American Journal of Physics 91 (2023), 819-825. Free at pubs.aip.org/aapt/ajp/article-

Masses, sizes, and relative densities of objects in our Universe. The diagonal white dashed lines are lines of equal density. Gravity and quantum uncertainty prevent objects of a given mass from being smaller than their corresponding Schwarzschild radius or Compton wavelength. Schwarzschild black holes lie on the black m / r = 1 diagonal line which is the lower boundary of the “forbidden by gravity” region. The masses and Compton wavelengths of the top quark (t), Higgs boson (H), proton (p), electron (e), and neutrinos are plotted along the Compton (mr = 1) diagonal line. Among these, the top quark has the smallest Compton wavelength, because it has the largest mass: 173 GeV c^2. The smallest possible object is a Planck-mass black hole indicated by the white dot labeled “instanton”.  The smallest observable (not yet evaporated) primordial black hole (PBH) that could have survived until today has approximately the same size as a proton. The large low-mass black dot in the SMBH (supermassive black hole) range is the 4 x 10^6 solar mass black hole at the center of our galaxy, while the more massive large black dot is the black hole Ton 618. The dashed horizontal line emphasizes the orthogonal symmetry of black holes (m / r = 1) and particles (mr = 1). Our Universe is represented by the “Hubble radius” and has a mass and size that places it on the black hole line.

iRobot apparently just declared bankruptcy, so if you have an internet connected one and want to retain control if the cloud platform vanishes, take a look at github.com/koalazak/dorita980# and stash that information somewhere safe (and note that it changes if you ever factory reset the device, so try not to do that)

공공투자가 필요하기는 하나, 부총리가 버블이 절대 아니라고 강변하는 걸 보니 쎄한 건 어쩔 수 없군...

14일(현지시간) 워싱턴포스트(WP) 등에 따르면 버지니아주 하노버 카운티 관계자들은 지난달 이 지역 주류 판매점에 침입해 유명해진 라쿤이 이전에도 여러 상점에 몰래 들어간 것으로 의심되고 있다고 전했다. 하노버 카운티의 동물보호국 직원인 서맨사 마틴은 현지 팟캐스트에 출연해 이 라쿤이 주류 판매점과 같은 건물에 있는 무술 도장과 차량국(DMV) 사무실에 침입했던 라쿤과 동일범일 가능성이 높다고 말했다

박석운 위원장님 성함이 익숙하다 했더니 카뱅심규협 선생님 오시기 전에 뵙던 투쟁 후원 계좌주셨음 (당시 거부권거부행동 명의) 주요 구성원에 원내진보야당들이나 광장단체(전여농 등)들의 면면도 보이는 만큼 실효성 있고 과감한 사회대전환의 계기가 되길 바랍니다.

BASE FOODからラーメン出たのでプロモーションを含まないレビュー

美味しいという評判と美味しくないという評判どっちもあったので気になって買ってみた

結論...

:yawn_javasparrow:​なんとも言えない​:yawn_javasparrow:

不味くはないけど美味しいかと言われるとYESとは自信を持っては言えない
まずいかおいしいかの2択であればおいしい
おいしくないことを覚悟して食べたら意外とおいしい

という感じ
かやくはカスみたいなのしかないのでほぼ麺とスープだけ食す感じになります
麺はもちもち感みたいなのとはほぼ無縁で、蕎麦をラーメンのスープに入れましたという感じ
スープ自体は普通に美味しい

この「不味くなさ」で各種栄養が摂れるならアリかと思った

정확히 말하면 미국은 시가지의 밀도가 매우 낮아서 질적 수송시스템에 가까운 철도 이하 대중교통이 채산을 맞추기가 굉장히 어려운 구조고, 여기에 계급이나 인종분리 목적으로 대중교통의 관리수준이나 펀딩이 저열했고 이게 부정적인 피드백이 반복된 결과가 지금의 상태쯤 될겁니다. 그 100키로쯤 뻗으면서 근린상가같은게 허가되지 않는, 인종분리를 배경에 깔고 만들어진 서버번이 그 근본적인 원인이라 할 수 있겠죠.

Being black on the fediverse is like being black in the pacific northwest.

There are some safe places, outside of those, things can turn hostile incredibly quickly.

There are lots of well meaning white people, but precious few that will actually do the work to understand the simple words that you're trying to share with them.

There is an overall, institutional lack of willpower to *do* anything to fix the negative environment for black folks.

And, ultimately, it can slowly chip away at you.

이야아 올해 멘토링했던 친구 중에 PwC에 취업했다고 연락 받았다! 므찌고 자랑스럽다!

그냥 한 석달 정도 같이 오픈소스 플젝 기여하고, 중간에 커피챗 두어번 하면서 라떼는 마리야 한 것 말고는 없는데 도움이 많이 됐다고 하니 저야말로 감사감사.

이제 거길 발판삼아 해외로 나가즈아! #컨트리뷰션아카데미
