ta solidarité ressemble plutôt à une forme d'altruisme (qui est un autre sujet, mais peut être pas tant que ça... je pense qu'on peut être solidaire avec des gens qu'on ne connait pas, et altruiste avec sa famille)

au début de ma thèse, j'ai redécouvert plein de choses qu'il avait faites dans les années 1970, c'était brillant... je l'ai beaucoup croisé entre 2000 et 2010 en gros, et on parlait de modélisation statistique, jamais d'autre chose...

Major languages spoken in Toronto (other than English) by neighbourhood

by Alex McPhee
pronghornmaps.com/toronto/
A detailed map illustrating the most spoken mother tongues (other than English) in Toronto. Different languages are represented by distinct colors overlaid on a geographical map of the city and surrounding areas like Mississauga, Etobicoke, York, North York, Scarborough, Vaughan, Markham, and Pickering. Large labels indicate areas where specific languages are prevalent, such as Mandarin, Cantonese, Italian, Portuguese, Tamil, Urdu, Spanish, Persian (Farsi), Greek, Bengali, Serbo-Croatian, and Ukrainian. Smaller charts at the bottom provide statistics on the number of speakers for the top languages, including English. The map also shows the boundaries of residential areas and major roads. A legend indicates the language families represented by the colors, such as Sino-Tibetan (Mandarin, Cantonese), Indo-Aryan (Urdu, Bengali, Tamil, Persian, Greek), Romance (Italian, Portuguese, Spanish, French), Slavic (Serbo-Croatian, Ukrainian), and others like Tagalog.

Is it just me, or has the “we care about climate” and “diversity & inclusion matter” momentum cooled recently? Colleagues crossing the Pacific/Atlantic 2–3x/semester for seminars, fewer/no hybrid conferences, and more speaker lineups that are overwhelmingly male. Shared experience, or biased sample?

How Google Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it
I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.
