僕はむかし久しぶりにジョギングした時に若かったころのつもりで膝を酷使しすぎてしばらく痛かったので今はジョギングするときはちゃんとした値段のランニンングシューズを履いて慎重に足を運ぶようにしてるよ

Mildly cursed factoid about UNC paths:

- UNC Paths can contain IP addresses such as \\192.168.1.1\share
- IPv6 addresses are supported as well
- IPv6 addresses contain colons
- can't have colons in Windows paths since colons are reserved for drive letters

So Microsoft came up with the the ipv6-literal.net domain that's special-cased by Windows so you can to write IPv6 addresses in UNC paths as 2a0e-3c0--21.ipv6-literal.net without it hitting any resolvers.

There’s a new website feature related to !

When viewing objects in OSM that have a Wikidata tag, you can now click the Wikidata icon to turn the opaque QID values into human-readable info (plus a link to Wikipedia if any).

github.com/openstreetmap/opens

This integrates the functionality that @ZeLonewolf’s browser extension provided directly into the OSM website.

채권도 현금(MMF)도 세금 안내고 대신 이자율 낮은것으로 했다 하여간 어떻게든 매년 3-4%이상의 수익은 내야 본전치기를 하는것임. 사실 이런 고민은 안하고 싶은데 애시당초 정부와 금융 시스템 자체가 글러먹은 구조인것이 문제이다 싶음...

적립식 투자하려고 했는데 원래는 주식:채권:금:현금 = 1:1:1:1 하려고 했지만 소심해서 야 이게 어떻게 주식가치가 앞으로 유지가 될까 싶은 쓸데없는 걱정이 들어서 일단 0.5:1:1:1만 했음. 401k도 넣고 있지만 매달 이렇게 더 넣어야할듯. 최대한 팔지 않는것으로... 수익 잘내도 미국정부가 다 띠어감 ㅋㅋㅋ 한국정부가 상대적으로 천사라고 느껴질정도로 호로록 다 빨아드심...

a pragmatist is someone who realizes you can absolutely place an artillery battery atop the unnavigable mountain if your corps only carries it piece by piece on foot

one who calls themselves a pragmatist but says that difficult thing is unreasonable simply wraps their despair in a fiction of reason

Ok, können wir etwas vorsichtig sein, die Verantwortung kann nicht auf ihr alleine abgelagert werden. Das ist nicht richtig. Sie wird bedroht, D. Baer sagt dazu ein bisschen mehr Resilienz erwartet sie schon. Das produzierte Aufregung, ist aber eigentlich dem 'MUSS' im OP sehr nahe. Die Gesellschaft/das System/die Politik muss es sicherstellen, wäre passender.

(Denke, wir meinen dasselbe... 🤔)

@cocolowres @TwraSun

Sehe ich ähnlich. niemand kann die Frau dazu zwingen und niemand sollte es tun.

Es sollte aber auch klar sein, dass die SPD im Falle, dass sie nicht antritt, die CDU richtig hart bezahlen lassen muss. Das muss so teuer werden, dass die CDU so nen Stunt nur einmal probiert!

Leider fehlt mir der Glaube in die "Sozialdemokraten" was das angeht.

so normal people aren't conscious of making eye contact the entire time they're doing it and constantly calculating how long they should do it and wondering if they're doing it right and constantly asking 'is this good? have I done it long enough? should I stop? is it weird now?'

huh

At 2024, our volunteers did a lot of work such as: video production and editing, translation, and transcribing. Other conferences work AV team, but PyLadiesCon didn't. It was all volunteers and a lot of work.

This year, we're trying to ease volunteer overwork, so we contacted AV vendor, asked what it would cost them to do all of this.
One vendor said 8K - 13K USD 😵

Moral of the story:
- Say thanks to volunteers.
- Sponsor conferences.
The end.

The big thing about Smalltalk isn't objects or classes. The big thing, the thing that's often missed, is message passing -- which doesn't depend on classes or the like. Conceptually, a message is just a word or symbol, and a list of IDs that point in some way to whatever other objects are involved.

Smalltalk's syntax is built around message passing, not around objects and class hierarchies.

"Comments go in double quotes in Smalltalk."

| foo |
"Declare the temporary variable named foo"

foo <- SomeClass new.
"Send the message 'new' to SomeClass, and make the variable 'foo' point to whatever SomeClass sends back as an answer.

foo doSomething.
foo doSomethingElse.
"Send foo a couple of messages."

This is not a syntax that depends on anything other than these principles:

  1. There are named objects.
  2. An object can send any message it wants to any other object it has the name of.
  3. An object can receive any message from any object.
  4. On receiving a message, an object can send one or more messages, and finally return the id of another object or itself as the answer to the message.

Nowhere in the syntax is there anything about classes or inheritance or any of that.

우분투는 좀 깊게 쓰려고 하면 아직 부족한 점들이 좀... 자체 패치 많이 하는데 비해 그에 대한 테스트나 문서화는 아직 부족한 느낌. 대충대충 취미용 리눅스라면 이러나 저러나지만 엔터프라이즈급까지는 아직 갈 길이 남아있는 듯.

Speaking from experience: Taking a risk by calling things out can be a very isolating experience. Don't applaud people that do. Do as they did: Take a risk, speak up, call shit out.

Because the more people do so, the less risk everyone has to take. And eventually what was once daring to say has moved into the realm of ordinary again.

The project to formalize in Lean the classical Carleson theorem on almost everywhere convergence of Fourier series, and a modern generalization of that theorem to more general metric spaces, has announced a successful completion of its goals: leanprover.zulipchat.com/#narr .

It seems that the process, while lengthy, was relatively smooth; there were some technical issues (for instance, whether to work with norms that take values in the non-negative reals, or extended norms that take values in the extended non-negative reals), and some key definitions had to have their formalizations modified at some stage of the process to make certain lemmas formalize properly, but overall no major mathematical issues were uncovered.
