Okay, so: once you’ve nicked £90m in assorted crown jewels from a national museum, I think it’s safe to say you no longer fall into the “petty crime” category even if you haven’t previously been noteworthy in your field.

As I said re: France - a scenario where aggro reactionary centrists fight it out with the far right is fine by reactionary centrists, because they will be in charge half the time. Their enemy is even softly left wing people, because a country that has left politics has no need for aggro centrists.

The reason that javascript has semicolons is because newlines are invisible, so the compilers couldn't see the ends of the statements. Then around 2016 computer vision got good enough that we could drop them though.

For Americans, not only is this not recognizing a Palestinian state but it’s effectively conditioned on said hypothetical state being demilitarized and thus incapable of self-defense.

My objective is to help figure out how to reduce compile times in async-heavy projects by telling you which futures are worth erasing. Might work on surfacing call-graph depth next.

« Choose France for Science » : le oui mais des chercheurs américains
Première université française à avoir fait un appel du pied aux chercheurs américains, Aix-Marseille présente ce jeudi ses premières recrues. Mais il ne faut pas s'attendre à des arrivées massives. Car les scientifiques installés outre-Atlantique s'interrogent : la France a-t-elle les moyens de ses ambitions ?
