New abomination: a tool that spawns a shell session where there are no consequences It uses overlayfs to redirect all writes to an overlay upperdir instead of messing up the real filesystem. Ditch all changes just by exiting the shell session: github.com/vikmik/scratch

@spimescape @halvarflake For ex, the 2025 math entrance exam was covertly about k[x]-modules, quivers, the fundamental theorem of finite abelian groups and other things which are typically way beyond the reach of a 2nd year uni student, but somehow made accessible with some cleverness.

@spimescape @halvarflake That said, this question could be accessible to a very good/motivated HS student given the right definitions/guidance. In general, ENS exams are typically about graduate/postgraduate notions carefully repackaged for 2nd year uni students.

The fact that this is an *entrance exam* question shows the madness of the french university system tbh. I'm a fan of David and his work, but I'd send my kids abroad to study before entering the madness that is the entrance exam for the "grandes écoles".

@MarcJBrooker FWIW the other answer seems correct though - I arrive to another equivalent expression using a completely different method (computing the cardinality of the union of the complement subsets).

@MarcJBrooker To take a more concrete example: i=1, |P|=4, q=3, N=2: (e_1, e_2) = {(1, 2, 3), (1, 2, 4)} can be drawn both by fixing '1' to be part of the i-sized intersection (and drawing (2, 3), (2, 4) for the rest), as well as fixing 2 and drawing (1, 3) and (1, 4) for the rest.

This answer appears to be incorrect (in that it seems to give right results only for n=2), but I can't find the gap in the logic: math.stackexchange.com/a/1079204 Anybody feel like flexing their combinatorics skills and explaining?

This paper on Monte Carlo simulations absolutely blows my mind. h/t @inf_0_

@seanhn Nice! We also got a bit of summer here today twitter.com/NWSSeattle/sta…

Summer has arrived in Ireland! It's scheduled for next Wednesday. Don't miss it.

@Xiatian @mjg59 That's some good eMMC grinding! I think Tesla took something like 8 years before they had to recall a lot of their cars that were writing logs on a 8GB eMMC (talking about tesla.com/en_AU/support/… )

@mjg59 I saw these die in less than a year in cheap Windows laptops used purely to dump a pneumatic tube system’s logs, five is a real achievement

Oh right the reason this device is unhappy is that its eMMC has stopped working cool cool

@b0rk "gron" (with grep) as a replacement for jq when I'm too lazy to figure out the right jq incantation github.com/TomNomNom/gron

what are your favourite newer command line tools? like ripgrep (grep replacement), fd (find), exa (ls), bat (cat), etc

@seanhn Never done that, but I've seen lots from cruiseamerica.com on the road - I'd guess this is the most common option

Any of my followers ever taken an RV around West coast USA? If so, where did you rent from?

@colmmacc @hadestown From the same singer: youtube.com/watch?v=KehwyW… (maybe not a hit song either, but still fairly famous)

@colmmacc @hadestown Maybe not a "hit song", but still a piece of pop culture from the 2010s: youtube.com/watch?v=vU8eL2…

Has there been a hit song with a bass lead vocal since the Crash Test Dummies? I can't think of any. @hadestown is interesting for having a lot of bass lead songs too, but that's a musical.

@RicciFlat Anything else I could have fun with, but DiffTopo was the first subject I felt I wasn't able to play with in a meaningful way. I found it deeply uninteresting in itself - it felt too arbitrary/man-made as a subject, for lack of better word (That was 10yrs ago - I quit math since)

@RimSarah This looks like a sliced "pain feuilleté", like this with a different shape: lacuisinedebernard.com/2018/02/pain-f… Never had this one, but some bakeries in France make it with leftover croissant dough, so the name checks out. It's marvelously addictive, I would not call that a crime :)

@MWasielewskiJr @Google Not that you'd care now, but for international mobility (France also), I picked the cheapest Tello plan ($5/month or something). Only works over Wi-Fi calling while outside the US, but that's enough for MFA and receiving/sending calls

@MWasielewskiJr @Google Also MFA doesn't always work through GVoice (some companies disallow VoIP numbers afair - hell, some even disallow phone numbers backed by prepaid plans - not sure how that works). Main reason I stayed away from GVoice

Do NOT, under any circumstances, port your phone number to #GoogleVoice. @Google has effectively stolen my number and because it's a "free" service I have not been able to get any effective help to get my number back. Now I have lost access to any phone-based MFA. A 🧵(1/9)

@iximeow "success is a lousy teacher"

@danluu I think it's more than 41 if you add up all the editions of Forbes that produce such lists. Forbes NA has 23 lists Forbes Asia has 12 Forbes EU has 13 Then add Forbes Africa, Middle East, France... Even Forbes Monaco! forbes.mc/30-under-30 That's 52 and there's probably more

I'd been wondering why I see so many people who haven't done anything particularly interesting with "Forbes 30 under 30" on their bio and it turns out there's Forbes has 41 "30 under 30" lists per year, so it's actually "1230 under 30 each year".
