Moziila didn’t have the ressource to keep a "subscribe to RSS" button in Firefox but has the manpower to build a full IA inside your browser.

And that’s all you need to know about the end of the web and the IA bubble.

I'm just now coming across this 2019 quote from OpenAI's Sam Altman in response to a question about how the company plans to make money: "The honest answer’s we have no idea. We have never made any revenue. We have no current plans to make revenue. We have no idea how we may one day generate […]

Over more than a third of a century, Alfie Kohn has offered a multifaceted defense of progressive education as well as research-based critiques of rewards and punishments, grades, standardized testing, homework, competition, and other aspects of traditional schooling (and parenting). If all his books and essays have one thing in common, however, it’s that they are extremely inconvenient to read while driving, exercising, or making dinner. Thus, when he learned (just a few weeks ago) that something called “podcasts” had been invented….well, you can see where this is going… Each episode of _Kohn’s Zone_ offers 20-30 minutes of provocative reflections on a topic having to do with teaching and learning — or with human behavior more generally; occasional longer segments feature conversations with leading experts in education. Watch this space for new episodes, which will appear as if by magic every two weeks or so. You can listen on any of the Big Tech podcast platforms or, better yet, here on this website. Links to all available episodes appear below, and if you’d like to be notified as soon as new ones are added, just click this button: Remind Me ** _A note from Alfie Kohn_** : I made two decisions when I decided to start this podcast. The first was not to accept ads. The second was to avoid putting certain episodes behind a paywall (or offering special content only to those who pay). But this means that I depend on the generosity of everyone who listens to help cover the production costs. So: Can you afford a modest contribution — ideally on a regular basis, since a podcast, after all, is not a one-shot event? If so, I’d be grateful if you’d support the project with whatever amount seems fair to you. (Your generosity will also confirm the thesis of my book _The Brighter Side of Human Nature_.) Oh, and if you enjoy the podcast, please tell other people about it. Thanks! Please click the button below to donate. If you don’t see a button, just use this link.

A new episode of my podcast, Kohn's Zone, just dropped -- "Making Kids Work a Second Shift": Is it time to stop focusing on how much homework kids are assigned and take a step back to ask whether research, logic, and values support requiring any homework at all? https://www.alfiekohn.org/podcasts/

L'Europa lluirà braçals amb la bandera de Palestina: "Els nostres valors ens impedeixen ser aliens a les vulneracions dels drets humans" Els primers equips de l'Europa lluiran un braçal amb la bandera de Palestina aquest cap de setmana. El club ho fa per defensar la vulneració dels drets humans.

Proud to be a member of my local football team CE Europa. They will play their next game with special armbands to show solidarity with Palestine (this is in addition to their regular No to Fascism patch).
