Hapanvelli on Virolahden oma perinneruoka, joka tehdään herneistä, perunasta ja hapanleivän taikinajuuresta. Se on yksinkertainen, hapahko ja täyttävä keitto, jota on syöty Kymenlaaksossa jo sukupolvien ajan.

For some reason my feed is full of people claiming baseball is the best game ever.
FYI, a little more than a hundred years ago a Finn Lauri Pihkala saw baseball being played and found it wanting. He created something greater: pesäpallo.

Mathematician Karl Weierstrass was born #OTD, Halloween, in 1815. 🧪 🎃
The fools at The Academy all said he was mad, but he showed them all in 1872 when he announced that he had created a MONSTER. Let's learn about the terrible thing he did.

Beautiful adoption S-curve there when you even out short term noise. And most importantly, it goes up to 100%.
It's absolutely astonishing: In just about 13 years, Norway has skyrocketed from virtually no sales of zero-emission battery electric vehicles to nearly 100% of all new passenger car purchases.

Näin siinä käy kun muut pelaavat teollisuuspolitiikkaa siinä missä Suomi tukee olemassa olevaa yritystoimintaa: investoinnit menevät muille maille ja osaaminen perästä hetken päästä.
Aikoinaan Venetsian Murano oli lasivalmistuksen globaali keskus. Vuosien saatossa pppia ja tietoa vietiin mm. Amerikkaan, enempää ei ollut antaa. Siinä vaiheessa herättiin siihen, että kilpailuvaltti on menetetty.

Your regular reminder that Luddites’ goals and concerns are still very much relevant.
The term "Luddite" as a pejorative synonym for "technophobe" was a technocrat PR coup; that's not what Luddites were about. They were a labour movement fighting to give workers control over technologies which were advancing w/o oversight and rapidly automating them out of their jobs. Sound familiar?
