If you're someone who has "experience teaching CS topics in a university setting" and wants to jump ship to industry training, Jane Street is hiring for an educator to teach their new OxCaml set of OCaml language extensions. Pay is... well, a lot more than I make at a university.

Here is a rather lengthy write-up (in English) explaining why I chose #OCaml as my main programming language for my personal and professional projects!

How do you compute the midpoint of an interval bounded by (a,b)? Obviously just (a+b)/2. Alas, if you're working on a computer in floating point, it's not so simple... nice 28-page pedagogical article on what to do instead.
How do you compute the midpoint of an interval?
The algorithm that computes the midpoint of an interval with floating-point bounds requires some careful devising to correctly handle all possible inputs. We review several implementations from promin...

Here's a paper describing quantum computing using standard programming constructs, w/o the linear algebra!

The hope is that this will demystify quantum computing and serve as a formal foundation for reasoning about quantum programs.

« Et l'IA, alors ? »

À force qu'on me pose la question, j'ai fini par mettre à plat mon opinion sur l'usage de l'IA générative en traduction.

Ce n'est pas un article pour spécialistes, mais j'espère que ceux qui n'y connaissent rien en sortiront mieux renseignés.

It is very hard to accept, but it is no longer safe to move EU governments & societies to US clouds. Not only is it dangerous to do so, it is also likely flat out illegal in the near feature. We're trading convenience for utter dependence on a mad king. It should stop.
