Hapanvelli - Virolahti Hapanvelli on Virolahden perinneruoka. Hapanvelli on arvoituksellinen ruoka, joka osuu suoraan virolahtelaisuuden syvimpään olemukseen. Sen makua on vaikea kuvata sanoin, sillä makuja on yhtä monia ku...

Hapanvelli!

Sillä on oma suku elänyt jo aikoja. Yhdessä lohkopiirakan (hammasvahinkojen yleisin syy Virolahdella) kanssa ne lapsuuden mummomökkeilyn perinneruoat.

Pesäpallo field.

Pesäpallo field.

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.

End of history.

Black and white photo of Karl Weierstrass in his later years. His white hair is receding, longer in the back, and he is wearing a dark suit with a white collared shirt underneath.

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.

Well cultural purity norms can be relaxed for a day or night. Happy Kekri to y’all, landowners remember to get properly drunk in order to guarantee good harvest next year.

I moved to Paris at the start of this year without knowing almost any French. I’m just traumatized. And that map is nightmare material. 😅

Finnish ”e” is always pronounced as French ”é”, and ”ä” with the sound the French make when they see ”in” (like, how French pronounce ”Finlande” sounds to me ”Fääland”).

And all letters have corresponding sounds.

My French teacher always prepared for pain when she asks me to read French texts...

FIDES-II: Advancing irradiation experiments Members of the Framework held a meeting to discuss the latest results and review the experimental programmes.

We just concluded the autumn FIDES-II meeting in Idaho, USA. The Framework has been operating for five years, and it is great to see the results that have been produced. Thanks to Idaho National Laboratory for hosting the meeting.

Tai sitä aletaan tuottaa muuallakin kun hinta on kohdillaan. Tyyliin Kiinan harvinaisten maametallien viennin pysäyttäminen joku vuosikymmen sitten, yllättäen löytyi sitten muita reittejä niille.

Eivät nekään vähemmän siirtomaameininkiä, mutta niin.

Synnyttää investointipäätös. Minkä narun sitten löytäneet jolla työntää.

Ruotsissa tosiaan raportoivat jo ne keinot joilla EUssa voi ydinvoimaa tukea. Nyt ilmeisesti tosin tulossa ydin-IPCEI jossa sitten voi olla lisää työkaluja. Ehkä. Mutta nekin aika kansallisia panostuksia sitten.

Minä kun olen näin etäsuomalaisena nyt hieman pihalla, niin voisiko joku avata mitä Orpo oli aiheesta linjannut.

Yritin googlettaa, en löytänyt.

Muoto pysyy samana mutta funktio ei -linja: juustohöylä, lapio, kitara

Funktio sama mutta muoto ei -linja: juustohöylä, puuhöylä, teollinen leikkuri.

Keskelle tyyliin kirves, näyttää vähän samalta ja palvelee vähän samaa tarkoitusta.

Kyllä tuossa ruudukon saa miltei täyteen.

Tällä hetkellä useampi fuusioreaktoreita kehittävä startup kiertää maita puhuen siitä miten ovat tekemässä demolaitoksiaan maihin joissa on sujuvimmat säännökset ja tukea toiminnalle.

Nykyhallituksen linja on ollut pyrkiä sujuvoittamaan säännöksiä mutta epäilen että siitä (rahallisesta) tuesta jää.

Our joint paper on EU-funded projects ELSMOR, McSAFER, and EASI-SMR was just published! This paper is a review of these projects in a dedicated publication of FISA2025 conference.

I was the coordinator of ELSMOR, where we looked at safety topics of light water SMRs.

Probably should have used a smiley as that was intended rather a tongue in cheek way. Criticality in one year is rather… ambitious… target after all.

Reforming Nuclear Reactor Testing at the Department of Energy By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered:Section 1.  Purpose.

National Labs should not worry as the 4.7.2026 criticality deadline is explicitly in a project outside national labs.

National labs have separate 2 years from application to operation deadline. So they get to be busy also.

Well originally Israel claimed Iran was weeks away from working weapon whereas others assumed couple of years.

Now Israel claims their actions delayed Iran by years when others say by months.

But at least all agree now that Iran is few years away from working weapon.
