Neděle: Rusko aktivovalo všechny své zahraniční influencery v koordinovaném informačním útoku na Evropu. Celé MAGA hnutí včetně jeho vrcholných představitelů zaplavuje digitální prostor výzvami k rozpuštění EU, revoluci proti „evropským byrokratům“ a vyzývá k podpoře krajní pravice, která prý jediná dokáže „zastavit cenzuru a civilizační proměnu Evropy“. Tomu všemu pomáhají technokraté jako je Musk nebo Durov, kteří navíc už v minulosti ohnuli algoritmy svých sítí tak, aby podobnou propagandu rychleji šířili. Ironickou tečku tomu dodávají představitelé Ruska, jako je Medveděv nebo Dmitrijev, kteří výzvy k „ukončení cenzury“ hojně sdílejí a komentují napříč všemi známými sítěmi, a to i přesto, že v Rusku jsou veškeré západní sociální sítě včetně Facebooku, Instagramu nebo X úplně zakázány. Zatím nejostřejší reakci ve vrcholné politice předvedl polský ministr zahraničí Sikorski, který Muskovi vzkázal, aby „odletěl na Mars, kde mu nikdo nacistické pozdravy cenzurovat nebude“. Klíčovou informací ale je, že Rusko si (samozřejmě) přeje rozpad EU a NATO, aby mohlo snáze napadnout jednotlivé státy. A každý, kdo usiluje o to samé, je – ať už vědomě, nebo nevědomě – agentem Ruska. I kdyby to měl být americký prezident. A děje se také tohle facebook.com/dnesnaukrajine.cz:

Now that it's consistently below freezing we can experiment with making ice outside. First attempt with a shallow plastic cylinder, but only the top and sides really froze after 12 hours.
Last year I used a little goat cheese “pyramid” container and got a wide variety of results (2nd & 3rd photo). I think distilled water produces the clearest ice. No idea on what causes the spiky air bubbles.

a round cylinder set up on edge where the inside isn’t frozen and the back facing away from us was more jagged ice and leaked water. This is standing up in the (frozen) bird bath with early morning sun behind it and you can just make out water in the lower 1/3 of the shape. The ice has lots of air bubbles in it.a truncated pyramid (trapezoid?) shaped ice block using plastic goat cheese container. The outside is mostly clear ice although there’s some patterns along the edges, inside didn’t freeze and so you can see the water level about 1/4 way down from top. It is sitting on top of wood and where the ice/water touches it the wood is illuminated and magnified a bitA really odd freeze where most of the outer edges are solid and perfectly clear ice, but there’s a round-ish blob in the middle that didn’t freeze and emerging from the top of it are spikes of air trapped in the ice. This is being held up to early morning blue sky so you can just make out finger tips along the bottom

The Little-Known Story Of The ‘Year Without A Summer’ That Saw Worldwide Famine And Widespread Snowfall In June

By Austin Harvey

"The summerless year of 1816 came after the eruption of Mount Tambora, the Indonesian volcano that violently exploded in April 1815 and sent clouds of ash into the atmosphere that blocked sunlight and caused global temperatures to drop."

"Woman Before the Rising Sun (1818), a Caspar David Friedrich painting showing the yellow-tinged sky that followed Mount Tambora’s eruption." - from article

탐라의 수학하시는 분들께 질문드려요....
처음으로 위상 수학 공부해보고 있는데, 책 보면서 어떤 개념에 대한 정의를 보고나서, 항상 뒤에 나오는 theorem이나 lemma를 혼자 증명해보려고 하는데 잘 안되는데 이게 욕심일까요ㅠㅠㅠㅠ 그냥 정리를 보고 그대로 음 이렇군 하고 이해만 하고 넘어가고 싶진 않아서요....ㅠㅠㅠㅠ 어떻게 해야 할까요

Turns out a bit more complicated than I thought.

- Prevent possible infinite loop if there's circular reference (if any of the post quotes an already-listed post)
- Max batch limit, if exceeds 30 status fetches, stop, show a button for user to manually "unwrap" another 30 - for very, very long chain of quotes
- Add a little CSS scroll-driven animation fun with `timeline-range-name`, so new, that even Biome (& Firefox 🥲) doesn't support it yet github.com/biomejs/biome/issue

Alerta Alerta 🚨🚨🚨

The Varia Mastodon account is no more!

Our GoToSocial instance database got corrupted, and when trying to fix it, everything went down. We won't be reviving the account at @varia but *may* choose to make another Fedi account... someday

RIP 😭

내가 느끼는 가장 큰 의 진입장벽이라면 activitypub 관련 코드랑 비즈니스 로직이랑 완전히 커플링되어 있는 것도 좀 큰 것 같은데, 어떻게 계층을 분리할 수 있을지 고민임.

Misskey도 계층이 잘 분리가 되어있어서 군데군데 테스트가 적당히 짜여져 있는데.... 당장은 OpenAI Codex/Claude Code on Web으로 짜도 기여할 수 있을 정도로 구조를 잘 다듬긴 해야겠다는것

a high-profile software project proudly announcing that it's going to start "using AI" is basically the same thing to me as seeing a big "this repo is archived" banner. perhaps even worse in some respects? intentionally or not, the message it sends is "we don't really enjoy programming and we don't want to work on this anymore, but rather than retire the project we're going to do a really lackluster job from now on". like if your favorite coffee brand proudly announced "now 20% more sawdust"
