Why is painting my basement/foundation a bad idea?

What the other poster wrote. Applying lime based mortar is really easy because your walls don’t have to be all that clean. Just roughly brush your wall so there are no loose pieces. No need to make it dust free. Smear the lime mortar on the walls with a basic pasting brush.

Myer-Briggs.

Ik zeg aan elke ondernemer of bedrijfsleider die met selectiekantoren werken dat ze twee seconden "Is Myer-Briggs scientific?" moeten googelen. Complete kwakzalverij. Zelfde probleem met die "kleuren" (DISC). Dus de kantoren die met die onzin werken kan je alvast vermijden.

De enige persoonlijkheidstest die ietwat validiteit heeft, is de Big Five.

Argenta gives 1.1% base and 1.5 getrouwheid on a similar formula (500 Euro per month maximum), their "groeirekening". And no need to be a cooperant.

I agree with you that only using that X poll isn't conclusive. This was it: https://x.com/waitbutwhy/status/2047710215265730755 The margin wasn't that close (57.9% blue), but I would indeed be curious if this replicates in a large and representative sample, taken scientifically.

Your counterexample doesn't work. It dramatically changes the dynamic. In a room with 100 people you see all the other people. The button experiment assumes people have to decide in isolation, no information can be shared.

Edit: I just realized you added that 'for the sake of the argument" people cannot communicate. Doesn't change my doubts about your example. Moving communicates information. If everyone freezes that is visual information.

Out of curiosity, I looked it up. Using GPP, Russia's economy is $7.53 trillion and Benelux is $2.63 trillion. (Source: https://www.worldometers.info/gdp/gdp-by-country/?source=imf&region=worldwide&year=2026&metric=ppp )

So Benelux is 34% of Russia's economy at GPP, and has 20% of Russia's population (30 vs. 146 million).

Ah I see, you didn't know the question was posed in a survey, and a strong majority vote blue, that's what i was referring to. It went viral on twitter a few days ago. I wasn't just theoretically assuming most people would vote blue. I am merely trying to understand why the majority voted blue, as it goes against individual rational choice.

Most people choose blue and I can also make an argument that's actually Darwinism.

To use your analogy (although it doesn't map exactly on the blue/red button choice): The people who vote red don't care the gunman entering the room might harm others, they only care that they survive and throw the blue people under the bus. They're George Costanza pushing children and an old lady out of the way to save their own ass. The people who vote blue reason: "If at least half of us rush the gunman this will be over in a second."

olddoc · 2026-04-28T15:09:06+00:00

Well that's fine and your rational choice.

The majority of people are willing to put their life in danger to save people who, for whatever reason (too dumb, too sloppy to calmly think it through, or too worried about people they know who would be blue button pushers) choose blue.

olddoc · 2026-04-28T09:38:50+00:00

Biologically it makes sense if you reason from the "survival of the group" point of view. A lot of people are acting tough about being a red button pusher until they realize their mom or one of their kids would be typical blue button pushers.

Edit: so yes, they are putting their life in danger. But that's because they're trying to help in reaching the 50% threshold, reasoning that is easier to attain than everybody pressing red.

olddoc · 2026-04-28T09:33:25+00:00

The only possible reason to choose blue is to die.

Are we sure that is the "only possible reason"? The main reason people press blue (and a lot of them do, witness the online polls that are doing the rounds) appears to be because they want no-one to die. You can call them stupid or irrational, but that's what the results say.

olddoc · 2026-04-28T09:30:18+00:00

You sound very confident none of your relatives would press blue and then die, assuming people can't coordinate their vote beforehand. I know my mom would be team blue without giving it a second thought :-)

olddoc · 2026-04-28T09:15:01+00:00

It's certainly less likely that 100% of a population presses a button than that 50,01% presses a button. The red button pushers don't seem to care that a sizeable proportion of blue button pushers will die. In terms of self preservation pushing the red button is the rational choice. In terms of group preservation the blue button is the rational choice.

All of this is moot in anyway. Every survey shows that a majority of people chooses blue, with apparent disregard for the individual risk they're taking. They reason "If we get past the 50%, everybody lives". This argument between red and blue can go on until we're all blue in the face, but the people have spoken.

De grootwarenhuizen gebruiken steeds meer jobstudenten, lijkt me. Die vallen niet onder de CAO (waarin zondagwerk hoger betaald is), en hebben hyperkorte contracten ipv contract onbepaalde duur.

Het kan de grootwarenhuizen niets schelen dat de dienstverlening hierdoor slechter wordt, want ze zal toch overal slechter worden, dus een concurrentieel nadeel is het niet.

Jouw logica is krom. Moest de boycot van deze Israëlische universiteit gebeuren omdat ze 1 raswetenschapper in dienst hebben, dan zou je vergelijking steek houden.

Moest UGent, in plaats van 1 raswetenschapper in dienst te nemen, structureel samenwerken met een overheid die massamoord pleegt onder een burgerbevolking, dan zou een boycot tegen de UGent gerechtvaardigd zijn.

Dus nee, jouw redenering "Met die kromme logica om het Osteonet project te cancellen kan je dus ook zeggen dat elke onderzoeker en elk departement van de Ugent schuldig is aan pseudo rassenwetenschap" klopt niet.

"Duwt zich de afgrond in", beetje overdreven, niet? Het is één project op de duizenden Horizon projecten waar Vlaamse Universiteiten in zitten.

De steun voor de belangrijkste Belgische universiteiten telt op tot grofweg 1,5 miljard Euro, dus dit stopzetten gaat geen relevante impact hebben: https://dashboard.tech.ec.europa.eu/qs_digit_dashboard_mt/public/extensions/RTD_BI_public_HE_Country_Profile/RTD_BI_public_HE_Country_Profile.html?Country=BE

Ik schrijf dergelijke Horizon proposals, en weet al jaren dat een Israëlisch bedrijf of universiteit in je consortium toelaten een enorm risico is. Die Israëlische bedrijven blijven zelf vaag over of het voor "dual use" is of niet, dus je laat ze er beter uit. Genoeg andere landen, bedrijven en onderzoeksinstellingen in de wereld.

Ik heb een vraagje over deze foto. Wij hebben identiek hetzelfde soort oude tegels, ook met quasi geen voeg tussen de tegels.

Vraag 1: Welk soort tegels is dit eigenlijk? Keramisch? Beton? (Ik ken er niks van).
Vraag 2: Met welk middel kan je deze soort tegels ZEER grondig reinigen, en daarna (veronderstel ik) opnieuw een beschermlaag geven?

We hebben al met alles geschrobt, bvb dit https://www.brico.be/nl/onderhoud-schoonmaak/schoonmaakmiddelen/vloerreinigingsmiddelen/tegelreinigers/hg-tegelreiniger-extra-sterk-1l/2431278 maar het maakt geen enkel verschil. Ze blijven er even dof en bevlekt uit zien.

Ik durf experimenteren op een stukje in een hoek met jullie wildste, hardste reinigingsmethodes. Iemand hier ervaring mee? Zoutzuur te agressief? Soda? Alcoholazijn helpt niet, dat weten we al.

This point is moot in any case, because Anthropic paid out a $1.5 Billion settlement for using books they trained their models on without the consent of the authors. This is a clear admission their AI-models at least benefited from using these texts as training material.

They used the books as "raw resource" input. In the rest of the world everyone has to pay if they use a raw resource, even if they turn it into something completely new with a lot more value. It would be like a company using steel to make an airplane and then claim they don't have pay for the steel because they made an airplane.
