Hacker Newsroom for 12 April recaps 7 major Hacker News stories, moving through small models vs mythos, firefox extension marathon, kernel ai rules, france linux push.

1. Small Models Vs Mythos

The next story is Small models also found the vulnerabilities that Mythos found, a post arguing that the real moat in AI cybersecurity is the system around the model, not the model size itself. The article says that when Anthropic’s showcase bugs are isolated and fed into cheap open-weights models, they recover much of the same analysis, including both detection and exploit reasoning on several of the examples.

2. Firefox Extension Marathon

The next story is Installing every Firefox extension, a post about scraping Mozilla’s add-ons API, combining multiple sort orders and even exclude-addons tricks to collect nearly the full Firefox extension catalog, then trying to install all 84,194 of them. The article turns into a comedy of scale: after a long chain of failed attempts, the browser finally launches with an absurdly overloaded profile and a bunch of strange side effects.

4. France Linux Push

The next story is France’s government ditching Windows for Linux, a news story that frames the move as a strategic response to dependence on US tech. The article says the ministries have until the fall to find a workable replacement, which makes this less like a symbolic gesture and more like an actual migration deadline.

5. Chimp Civil War

The next story is a BBC report about chimpanzees in Uganda that researchers say have split into rival groups and spent eight years in a violent feud, with at least 24 killings recorded, including many infants. The article traces the rupture to a few destabilizing shocks: deaths of key chimps, a change in alpha male, and a respiratory epidemic that seems to have weakened the group's social fabric.

The next story is South Korea introduces universal basic mobile data access, a news story about a nationwide fallback plan that gives millions of subscribers unlimited data at 400 kbps once their regular allowance runs out.
