@vicgrinberg anyhow, I didn't really have a luxury of not learning to speak Dutch enough to talk to bureaucrats, as I wanted to get a normal passport - 26 years ago there were no compulsory language tests, if the city hall bureaucrat was satisfied by your language command, they'd let you get the […]

@vicgrinberg Ik neem het aan dat je al meer Nederlands dan je collega's kent 🙂 Van mijn ervaring op cursussen Nederlands, Duits sprekende medestudenten startten met de leerar in Nederlands in minder dan een week kletsen (dat was ook, naast mijn stutter, waroom ik kon geen cursus Nederlands […]

@vicgrinberg misschien een collega zou eens tegen je zeggen: vanaf nu, uitsluitend Nederlands. Geen Engels, geen plattdeutsch. Nederlands.
Ikzelf, gelukkig, had wel eens zon' collega gehad, terug in 1999.

@chris__martin it already must be sending summaries of your Team chats to the Redmond's Monetization Department, just legitimate interest, you know, nothing personal...

@chris__martin you prefer not to separate problems from solutions? Anyway, github etc do allow you to create issues just for this.

@chris__martin I feel like I don't belong anywhere in particular, just to this planet. Nor that I really have a "home country".

@chris__martin the history which goes back too far. Large chunks of Europe are now populated by descendants of various tribes arriving from afar around 2000 years ago. A lot of mixing with the previous population took place, unlike the modern times colonization. A lot of places where population […]

@chris__martin this question is not well-posed, as nowhere in Europe it really makes sense to talk about "native inhabitants" in the US/Canada/Australia/NZ sense.

@stefano I presume your blogpost described L'Aquila area. I visited L'Aquila twice; first, in 1996, as a co-author of someone on the maths faculty of the University. They still had very old DEC machines, connected to the internet by modem lines, and I was […]

@chris__martin throw in what you get by computing volumes of bodies defined by multivariate polynomial inequalities, and you will get the all the interesting transcendentals, known as algebraic periods.

@chris__martin and I just paid my utility bill by a check, as the online system is down

@chris__martin ironically, they host quite a few cybercriminals. So a website where one can order a ddos attack is protected by cloudfire 🙂

@sheerluck I meant cvxpy, not cvxopt, sorry (corrected in my post)
November 18, 2025 at 6:39 PM
@sheerluck [[1, 3, 6], [0, 2], [4, 5]] is correct - you just need to check that no sets in sts.blocks() get the same colour.

PS. I can install cvxopt/CBC by
`./sage --pip install "cvxopt[CBC]"`
November 17, 2025 at 8:33 PM
@sheerluck well, as long as both answers are OK - did you check?

@dpiponi @BoydStephenSmithJr @TechConnectify did you say "teabag"? Oh dear... Teabags are akin to sex using a condom, pardon my analogy :] They restrict water flow to tealeaves.

Anyway, UK kettles are mostly crap just as well. We dumped a new Breville because it wasn't possible to get rid of […]

@briankrebs a .su domain? It's ought to point out to a physical person, a registrant, somewhere in Russia...

@chris__martin if you need to train yourself for NYC, try visiting London, or Hong Kong, or Tokyo.
I find inner parts of NYC much more livable than 95% of the rest of the USA - but I don't drive.

@tomkalei @hweimer I don't think there are technical barriers for making a federated version of arXiV. E.g. the DOI system works reasonably well, and points to many differently hosted sources just fine. Yes, for a federated system to be really reliable one needs a duplication of infrastructure […]
