Fascinating: Andrzej Odrzywołek claims in a recent preprint that all constants, operators, and functions typically found in a scientific calculator can be decomposed into nested invocations of the eml function and the constant 1, where
eml(𝑥, 𝑦) = exp(𝑥) − ln(𝑦).
https://arxiv.org/abs/2603.21852
Examples:
𝑒 = eml(1, 1)
−1 = eml(1, eml(eml(1, 1), 1))
𝑥 + 𝑦 = eml(1, eml(eml(1, 𝑥), eml(1, 𝑦)))
sin(𝑥) = a gigantic 100+ nested levels of eml

Despite being chronically online, I only learned recently that @npub1fdr…lvhs had published his latest book, #Enshittification. And because he is a great communicator, his 16-minute interview with #RonnyChieng on #TheDailyShow to talk about the book and the wider topic is very accessible. I guess I now have yet another book on my ever-lengthening reading list.

Oh nice! This is probably the biggest change to the core message format of #HTTP since HTTP/1.1 was released in 1997!
This new QUERY method would've been really useful for designing better REST APIs that otherwise relied on POST requests too much.
Also I wonder how many web browsers, servers, and middlemen devices already support this?
Lastly, the #Wikipedia article needs to be updated: https://en.wikipedia.org/wiki/HTTP

Today is Rizal Day, a public holiday in the #Philippines 🇵🇭 honoring the martyrdom of national hero #JoséRizal. Rizal was executed on 30 December 1896 after being charged for sedition and rebellion against the Spanish colonial government.
As a simple token, here is a photo I took in 2017 of a historical marker installed by the Philippines’ national historical agency in Berlin at the site where Rizal stayed while writing his first novel, Noli Me Tangere.

This time I rendered a map of modern-day Key West, #Florida, but with Spanish names because Spanish Florida still exists! 😝

I wouldn’t dream of trying this back in 2010, but I think the state of JavaScript + Canvas is good enough that I could do this now.
The original party render script uses the Cairo graphics library and HTML5 Canvas is essentially an almost direct counterpart.

In a disturbing update to the ANI vs. #Wikipedia defamation case in #India 🇮🇳, the #Wikimedia Foundation agreed to disclose user details of accounts that have added the defamatory content to the article about ANI, the litigious Indian news agency at the center of the case. What those user details could be there is no info, but I imagine that if these accounts have email addresses attached, then these would be included, as well as any recent IP addresses used.

Fortunately, the skies were clear enough that the asteroid #2024RW1 née #CAQTDL2’s meteor-fireball-bolide phase was visible and with plenty of videos taken.
https://www.imo.net/2024-rw1-atmospheric-entry-in-pictures-videos/
As already mentioned by many outlets, this was only the 9th time a meteor was predicted in advance which meant that lots of people were expecting it.

Various astronomers are reporting that a 1-meter asteroid (#CAQTDL2) discovered by the #CatalinaSkySurvey this morning will become a meteor by striking the atmosphere at around 16:39 UTC (12:39am local time) over northern #Luzon island in the #Philippines 🇵🇭.
No damage is expected but if there are clear skies tonight (Typhoon #Yagi / #EntengPH is in the area) people can expect to see an impressive fireball. 🌠
