My small British company was bought by Americans. I have just been formally reprimanded for sarcasm and sardonic commentary. I told the disciplinary panel I was grateful for the opportunity to reflect on my attitude going forward and would be certain to bear it in mind in future.

It's called a cron job
is there an AI that can perform repetitive tasks? Ex: login into an app, perform certain tasks everyday?

Advice to students: study fundamental topics that have a long shelf life.
#MCInterview | 🚨 "For a 20-year-old, the question is what specialty should I learn? You should study very basic things that have a long shelf life - mathematics, physics, basic computer science, applied mathematics. Those are things that would be necessary to understand and develop the next generation of AI system," says Meta's Yann LeCun Catch the full interview of @ylecun with @chandrarsrikant and @tsuvik👇 youtu.be/1IBYmEgY3_E?feature… #Meta #ArtificialIntelligence

Arctic Convoys - Bletchley Park and the War for the Seas by Dr David Kenyon is out today in paperback!📘 Dr David Kenyon explores the story of the war in the Arctic, revealing that the contest was more evenly balanced that previously thought. Battles included major ship engagements, aircraft carriers, and combat between surface ships. Amid this wide range of forces, Bletchley Park’s Naval Section played a decisive role in Arctic operations, with both sides relying heavily on Signals Intelligence to intercept and break each other’s codes. David Kenyon presents a vivid picture of the Arctic theater of war, unearthing the full-scale campaign for naval supremacy in northern waters. Buy it now!: amzn.to/3A8e9pU
