We're so relieved to see Germany reaffirm its opposition to the dangerous Chat Control proposal--the one that would mandate mass scanning of communications. Germany's long been a solid champion of privacy, and the news that it was considering backing mass surveillance was alarming. 1/

Нямаме разминаване, че “capacity in watts” е безсмислица и че допускането за константна ефективност е некоректно :)

...но би било коректно такива допускания да се уточняват в текста. Обаче такива технически детайли обикновено не вълнуват бизнес-хората :)

Електрическата мощност точно във Watts си се мери. Изчислителната – най-често във FLOPS, а FLOPS/Watt го интерпретирам като изчислителна ефективност. Ако изчислителната ефективност се вземе за константа, тогава дадените в статията GW могат да се приемат като мярка за изчислителна мощ...

Scientists revive old Bulgarian recipe to make yogurt with ants
Ants carry lactic and acetic acid bacteria that help coagulate milk, as well as formic acid to acidify it.
Scientists revive old Bulgarian recipe to make yogurt with ants. Ants carry lactic and acetic acid bacteria that help coagulate milk, as well as formic acid to acidify it. They even partnered with Danish chefs to create three recipes using ant yogurt. arstechnica.com/science/2025...

Изглежда, че в NIST използват везна на Kibble, за да изработват еталони: www.nist.gov/si-redefinit...
Нещо такова би трябвало да е по способностите на българската метрология, макар и не чак с ppb точност, която не е и необходима в 99.9% от случаите. А могат и готов еталон от да си вземат от NIST

Подемната сила зависи от обема на тялото и от плътността на флуида, в който то е потопено (въздух в този случай). Вакуумната камера нормално би имала различен обем от тежестите, докато и двете са във въздух в този случай. Следователно им действат различни по големина подемни сили.

И трите величини са константи, които са били установени с голяма точност при предишните SI дефиниции. За текущите SI дефиниции тези константи се фиксират на измерените преди това стойности. Така нямаш нужда от образци (за kg, m и т.н.), които да се пазят при специални условия – просто смяташ.

Kilogram - Wikipedia
Модерната дефиниция на килограма ми е по-интересна. Минава през константата на Планк, скросостта на светлината във вакуум и честотата на прехода между две основни състояния на Цезий-133: en.wikipedia.org/wiki/Kilogra...

Кантарът се поставя във вакуумна камера, предполагам. Друг е въпросът каква степен на вакуум е била постижима с технология от края на 19-ти век. Интересно ми е каква им е била дефиницията за "безвъздушно пространство", тоест какво е било максимално допустимото налягане в камерата.

Трябва да се уточни периодът от време, за което звездите се приемат за "фиксирани". Тук говорим за период от една година и всички звезди са достатъчно далеч от нас, че с добро приближение да можем да ги приемем за "фиксирани" (спрямо слънцето) в рамките на тази една година.

Zelensky displayed superior emotional intelligence on Fox News after the debacle today. He continued advocating for his country's security and defence. His empathetic, calm, self-aware reactions to what was an utterly unfair attack/vile condescension need to go into textbooks.

Това не е от вчера между другото. Обединението, изглежда, никога не се е случило в главите на една голяма част от (източно-)германците. Притеснително е също, че и в много от "черните" общини всеки пети е гласувал за AfD.

Why taking the time to play is important for learning and developer productivity.
Remember that new talk I was working on? I gave it last week at JFokus, it was the closing keynote. I got it down to 80ish slides and I'm really happy with how it turned out. It's about how play can help you learn, and how to apply it at work. Video and slides here

IT IS A COUP
This is what should be on every front page in 150 point banner headlines. All I have is this Substack but I lay it beneath your feet and pray to a higher power that I'm wrong.
This is what should be on every front page right now. What's happening in the US right now is an illegal power grab by a private citizen. IT'S A COUP.
It's a digital coup. It's Musk who's leading it. The consequences are terrifying. And it's coming for us next.
