이쯤되니까 금이나 달러사는게 문제가 아니고 콩이랑 감자 기르는 법 배우고 건강한 종자 사두는게 중요할거 같다는 공포만 스멀스멀 기어 올라옴.

A new post, on intriguing hints from the DESI survey data that suggests that the cosmological constant (aka "dark energy) might not, in fact, be constant after all. instagram.com/p/DIP0yy5oDUu

Cosmic Distance Ladder on Instagram: "When Einstein developed his general theory of relativity, he noticed that his equations predicted the universe could expand and then contract, or expand forever; but without additional counteracting laws of physics, it could not stay at a steady size indefinitely. In order to make his theory better fit the prevailing “steady state” model of the universe of his time, Einstein added a term to his equations, involving an unknown “cosmological constant” Λ (Lambda), that caused the vacuum of space itself to inherently expand and counteract the contracting force of gravity. Although evidence from the 1930s onwards favored an expanding universe (the “Big Bang” model) and Einstein removed this constant from his equations, reportedly calling it his “biggest blunder”, we now view this constant as one of the simplest forms of “dark energy”. But in the 1990s, two large research teams, headed by Saul Perlmitter, and Adam Riess and Brian P. Schmidt, respectively, precisely measured the distance from the Earth of supernovae designated type Ia (“one-A”). Both projects independently discovered that the expansion of the universe was not slowing (as they expected) but accelerating over time. The simplest way to explain these facts was to reinstate a (small) cosmological constant Λ, leading to the standard “Λ-CDM” model of the universe today (the CDM stands for “cold dark matter”). Perlmutter, Riess, and Schmidt received the 2011 Nobel Prize in Physics for the discovery. Now, new analysis from an ongoing survey using the Dark Energy Spectroscopic Instrument (DESI) suggests this acceleration is itself fluctuating in time. It seems dark energy, usually treated as synonymous with the “cosmological constant” is not actually constant after all, but potentially evolving. As the study confirms the existence of the mysterious phenomenon of dark energy, it simultaneously shows that there is much about it that we still don’t understand. The last rung in the Cosmic Distance Ladder is “How big is our universe?”. For now, each new result seems to suggest it is growing bigger than any previous model believed it could be. #DistanceLadder #astronomy #DarkEnergy #astrophysics #cosmology #DESI"

トランプパニックを見ていて、個の力の偏重が起こした現象だなーと思い。
力に任せた恫喝は、「交渉役」であるトランプに権力を集中させる、古典的な、もう動物の群れでもやってる手段だよなと思い。これ、個体に力を集中させていく基本ステップだ。

個の力を抑えることができるのが、ルール。
個人から権力を奪い、ルール、仕組みの方へ権力を持たせて、さらにそれが睨み合いになるようにする、というのが先達が時に命がけで作ってきた政治の力。

この2つを上手に使わないと、小さな生活は廻らない。
個の力を頼みすぎたり、英雄譚として喜んだり、逆に仕組みでガチガチにしてダイナミズムを失っても、生身の我々は良く生きられない。

みたいなことを長々と考えていましたが、先ほど誤って消しました。

Unityが中国で使えなくなる、という話を読んだ。どうやらまだ状況は流動的なのだけど、Unity China越しのアクセスには制限があるらしい。
関税の前の話なんだけど、100%を超える関税が動き出した今となっては状況はもっと深刻だろう。
中国政府がWTOに提訴して関税が下がるまでは米国著作権・IP無効にすると言い出す可能性もあるかもね。

to any academics who want their work to outlast their current hype cycle, the next publisher downsizing, or government book burning:

  • make your work available for free.
  • as a PDF or HTML document (or, fine, JATS)
  • from a URL that requires no login or javascript to access.

having your work only available behind some heinous publisher paywall or 'enhanced reader' is a straightforward statement that you don't care about your work being part of the shared pursuit of human understanding. it is, in fact, your job to make sure that your work available.

sincerely, someone trying to preserve your work.

박준규 shared the below article:

지적 재산권

정진명의 굳이 써서 남기는 생각 @jm@guji.jjme.me

지적 재산권에 대해서 이야기를 하려면 지적 재산권 제도를 통해서 이룩하려는 것이 무엇인지를 이야기해야 합니다. 저는 지적 재산권을 세 가지로 보는데, 기능을 실현하는 것에 관련된 것과(특허, 실용신안) 표현에 관한 것과(저작권) 공정한 시장을 위한 것(상표)으로 나눌 수 있을 것 같습니다. 상표는 조금 성격이 다르다고 생각해 따로 이야기하겠지만, 어쨌든 지적 재산권이란 어떤 이로운 것을 새롭게 생각해낸 주체의 권리를 보장해주기 위한 제도지요.

그런데 이 '생각해낼 수 있는 어떤 이로운 것'이란, 대다수가 저렴하게 복제가 되거나 복제된다고 해서 그 가치가 줄어들지 않는다는 특징이 있습니다. 기능을 실현하는 지식도, 표현된 이야기도, 가끔은 '이 로고가 붙은 제품은 좋다'는 믿음도 말이지요. 어떤 면에서 말하자면, '생각해낼 수 있는 이로운 것'이 제한없이 복제될 수 있는 상태가 편익의 합을 극대화할 수도 있을 것입니다.

하지만 이렇다면, 어떠한 노력을 들여서 복제될 수 있는 무언가를 만들어내는 행위가 경제적으로 보답받지 못하는 상태가 되리라고 생각할 수 있겠지요. 우리는 그런 행위가- 발명과 창작이 사회의 편익을 증가시킨다고 이해하고 있고, 그걸 위한 인센티브를 주고 싶다고 생각합니다. 지적 재산권은 제 생각에 그것을 보장하기 위한 도구입니다. 그러나 극단적인 경우를 생각해 봅시다. 지적 재산권이 개인에게 기한과 범위 없이 인정되고, 그것을 계속 물려줄 수 있는 거지요. 불을 쓰기 위해서 처음 불을 발견한 사람의 자손에게 사용료를 내고요. 누군가가 벽에 커다란 낙서를 해서 그것을 방송으로 보도하면, 그 낙서를 복제한 것이기 때문에 보도하기 위해서 저작권료를 지불해야 할 수도 있지요. 뭐, 그러면 안 되는 건 아닐 순 있지만, 사회의 편익이 그렇게 높을 것 같지는 않습니다.

제 주장은, 지적 재산권은 다음 두 상황의 균형을 맞추는 제도라는 것입니다.

  1. 지식과 표현이 아무 제한 없이 복제되어 지식과 표현을 만들어려내는 시도가 저해되거나, 사회가 원하는 만큼 이루어지지 않는 상황
  2. 지식과 표현의 복제가 너무 제한되어 사회가 복제로 얻을 수 있는 편익이 감소하는 상황

대부분의 경우는 1번 상황이 문제가 됩니다. 2번 상황은 꽤 이론적인 것처럼 보이지만, 충분히 주의해서 관찰한다면 사회의 어떤 문제는 2번 상황에 해당한다는 걸 찾아보실 수도 있을 것입니다. 이미 우리의 지적 재산권은 만료, 공정 이용과 같은 방식으로 동의 없는 복제를 허용하고― 다시 말해 제작자의 권리를 무한정 인정하고 있지는 않습니다.

두 상황의 균형은 사회의 영향을 받기 때문에, 지적 재산권이 어디까지는 제작자의 권리를 보호하고 어디부터는 보호 없는 복제를 허용하게 두어야 하는지는 그 사회의 변화에 맞추어 적절하게 갱신되어야 한다고 생각합니다.

I have a method of managing system and user program configuration that I think might be a little unusual these days?

That is, I use my system package manager to install the whole operating baseline of the machine. Maximum stability, minimal divergence from configuration defaults.

For those programs which I configure extensively - git, emacs, mu/mu4e, etc. - I compile from source and install *strictly* into ~/, usually with `PREFIX=$HOME make ...` or the equivalent. Very simple.

미중 무역 전쟁과 관련해 사람들이 미국만 걱정하고 중국은 별 걱정안하길래, 중국의 미국으로부터의 주요 수입품을 chatgpt한테 물어봤다. 1순위가 콩이라고 한다.

I started recording my dreams mid-2021 into an Obsidian vault, and now I'm at more than 700. I dream every **1.9 nights** :o and that's not counting all the mornings where I was too time-crunched. 188,000 words total.

Top 3 places:
- Suburbs I grew up at
- MIT
- School/classrooms

Top 3 conceptual motifs:
- Magic (lucid dreaming, telekinesis, etc.)
- Relationships
- Nightmares/sleep paralysis

Creatures (puppies, monsters, snakes, etc.) are the most frequent character encountered

Dense graph of hundreds of nodes. Red nodes represent places that the dreams take place at, such as MIT campus. Yellow nodes represent characters who appear in the dreams, such as friends, family, and creatures. Purple nodes represent recurring conceptual motifs or story archetypes, such as relationships or zombies or hands. The many little blue nodes represent one night's dreams, and edges from blue nodes to the others represent the dream involving some place (red), character (yellow), or concept (purple).

PostgreSQL 내장 전문 검색의 가장 큰 문제는 성능이 아니라, 색인을 만들거나 검색할 때 대상 언어를 지정해야 한다는 것. 당연히 언어가 섞여 있으면 제대로 동작 안 하고, 색인하려는 내용이 어떤 언어로 작성되었는지 모를 때도 곤란하다.

사람이 이익으로 움직였다면 성소수자들도 장애인들도 노동력으로 쓸 수 있게 관련 법과 시설 확충을 했을 것이고 외국인들의 노동을 적극 권장해서 경제를 살리는데 이바지했을 것임. 나라는 고위직들 kibun에 따라 각각 움직이고 서로 싸우고 헐뜯는다.
