La revanche de la Comtesse

Nouvelle frontière pour l'IA générative ? Les contrepèteries, fondées sur des inversions de syllabes et souvent déchiffrées de manière phonétique, échappent à l'intelligence des modèles les plus puissants.

Eden: NHS goes to war against open source

✇LWN
Par : jzb

Terence Eden reports that the UK's National Health Service (NHS) is preparing to close almost all of its open-source repositories as a response to LLM tools, such as Anthropic's Mythos, becoming more sophisticated at finding security vulnerabilities. He does not, to put it mildly, agree with the decision:

The majority of code repos published by the NHS are not meaningfully affected by any advance in security scanning. They're mostly data sets, internal tools, guidance, research tools, front-end design and the like. There is nothing in them which could realistically lead to a security incident.

When I was working at NHSX during the pandemic, we were so confident of the safety and necessity of open source, we made sure the Covid Contact Tracing app was open sourced the minute it was available to the public. That was a nationally mandated app, installed on millions of phones, subject to intense scrutiny from hostile powers - and yet, despite publishing the code, architecture and documentation, the open source code caused zero security incidents.

Furthermore, this new guidance is in direct contradiction to the UK's Tech Code of Practice point 3 "Be open and use open source" which insists on code being open.

Ils ont demandé à l’IA d’imaginer la dernière pièce de Molière

Et si l’intelligence artificielle pouvait ressusciter le génie de Jean-Baptiste Poquelin ? À travers le projet Molière Ex Machina, des experts en IA et des universitaires ont entraîné des modèles de langage pour produire une pièce inédite, des costumes aux décors baroques. Après deux ans de développement, le résultat de cette expérimentation sera dévoilé à l'Opéra royal de Versailles les 5 et 6 mai.

[$] Version-controlled databases using Prolly trees

Modern database and filesystems make pervasive use of B-trees, which are tree structures optimized for storing sorted lists of keys and values on block devices. Dolt is an Apache 2.0-licensed project that makes clever use of a variant of a B-tree to support efficient version control for an entire database. The data structure it uses could well be of interest to other projects.
