We really need to distinguish kinds of cyclists. They look similar ("on a bike") but have very, very different behaviors and desires, and these interact with other forms of transportation and density in different ways. - Group A: serious cyclists riding for exercise. These people want to maintain high power output and heart rate. They are riding bikes that cost > $5k (like the one in the photo). They are generally very experienced, comfortable with well-behaved traffic, and move at the speed of vehicles. They do not want to use bike lanes and every stop sign or light is an impediment to their exercise goal. They are generally deferential to pedestrians and work with cars and follow rules, but it's a different set of rules than they would use when driving. Average speed alone is ~18 mph or > 20 mph in groups. - Group B: commuters and explorers. These people just want to get from point A to B safely. They are uncomfortable around cars, and often do not understand them (think children). They benefit immensely from bike lanes and traffic calming, and in fact will often not even ride at all if those don't exist. They will follow traffic laws especially if those rules and the lighting and so on are developed with them in mind. Their average speed is something like 8–10 mph. - Group C: workers. These are couriers and food deliverers who are cycling because it is way cheaper and more versatile than a vehicle. Their goal is to move as fast as possible so as to increase their bottom line. These are the groups that have adopted e-bikes and other electric and small motor vehicles. This group is relatively new and growing and is ungoverned by custom or tradition. Unlike those in Group A, they often ride on sidewalks and at high speeds even in dense pedestrian areas, and, due to the motor assist, are often moving at speeds > 25 or even 30 mph. The law needs to respond to these groups differently. - The unfortunate reality is that the desires and needs of (A) are largely incompatible with a dense city like NYC. - Cities should do everything they can to accommodate and help out (B), especially because the benefits spill over to businesses and also help slow traffic down in ways that are legible to drivers and that don't result in individual resentment. - The law needs to be brought down like a hammer on (C), because they create the most disorder and pose the greatest danger to pedestrians.
Many states have stop sign as yield and stop light as stop sign laws which has been shown to increase cyclist safety. People on bicycles should ALWAYS yield to pedestrians where there is conflict/a tie. Assholes on bikes are less lethal than assholes in cars but not less noxious.

My toddler said "melatonin makes you sleep" and I thought "Can he be said to understand that? It's not like he knows what kind of molecule melatonin is or which receptors it acts on…" But then I don't know what kind of molecule melatonin is or which receptors it acts on either…

“It’s just matrix multiplication!” is actually the funniest cope because the fact it *isn’t* just matrix multiplication is very literally the reason any of this is happening.

Fa troppo caldo, bisogna rinviare l’inizio dell’anno scolastico a ottobre. La richiesta è partita da un appello online ed è stata raccolta da molti insegnanti, ovviamente da alcuni sindacati e persino da tanti genitori. Tutti giustamente preoccupati per le condizioni insostenibili e rischiose per la salute psicofisica di docenti, lavoratori e alunni. Servirebbero i climatizzatori nelle aule, ma non ci sono i soldi e soprattutto non c’è tempo. Ora. Perché in passato ci sono stati entrambi, ma entrambi sono stati sprecati. Quando nel 2020 c’è stato il Covid, l’Italia è stato il paese che ha chiuso le scuole più a lungo in Europa: 341 giorni, rispetto a una media di 138. All’epoca, una delle discussioni più importanti era l’aerazione delle aule: portare impianti di ventilazione in tutte le scuole era un obiettivo condiviso e prioritario. E le risorse, negli anni successivi, non sono di certo state un problema. Tra il Superbonus e il Pnrr sono stati spesi 450 miliardi di euro, ma non un euro è stato previsto per adeguare gli edifici scolastici all’aumento delle temperature: abbiamo messo i cappotti termici alle ville al mare, ma non l’aria condizionata nelle scuole. Così allo stato attuale, su circa 60 mila scuole, solo il 6-7 per cento ha la climatizzazione. Il ministro Valditara ha stanziato 20 milioni di euro, sufficienti a rinfrescare appena 3-400 aule: per gli inutili banchi a rotelle il governo Conte spese 120 milioni. Così, dopo sei anni e 450 miliardi, la soluzione è sempre la stessa: scuole chiuse. In fondo anche ai sindacati va bene così, d’altronde tra i tanti scioperi fatti – da Gaza al neoliberismo al climate change– non se ne ricorda uno per l’aria condizionata.  ilfoglio.it/cronaca/2026/09/…

I think almost every single time an adult said "you'll agree with me when you're older" when I was a kid, they turned out completely wrong. I think all the adults in my life were wrong about basically everything.

AI companies are racing to build superintelligence... without knowing how to control it. Let's take our future back from Big Tech. Join the call for a ban on superintelligence, until it can be done safely with public buy-in. #KeepTheFutureHuman share.superintelligence-stat…

This is a popular misconception - the people warning about AI xrisk are mostly libertarian-learning techno-optimists who took the OTHER side of those issues (except for accurately warning Covid was a serious risk in Feb 2020, which was prescient and deserving of Bayes points)

Sirio Telephone Società Italiana per l'Esercizio Telefonico Giorgetto Giugiaro, Italy, Circa 1987. 80's did bouba properly. It had a sense of orthogonality and sophistication under it. It is so over for modernity, GG. Go home.

I am very happy I am not Napoleon, and not only because he is dead. If you are unhappy that you are not Napoleon I think you have not looked sufficiently into Napoleon.
Many people are sad they're not Napoleon. The important thing is not to start an AI company about it.
