 MARK ZUCKERBERG BLAMES SLOWER SALES ON WAR, LAYOFFS ON AI COSTS IN
MEETING (3 MINUTE READ) [5]

 Meta CEO Mark Zuckerberg addressed the market's negative reaction to
the company's first-quarter results in a companywide meeting on
Thursday. He said the 8% drop in Meta's shares was due to investor
concern over an upward revision in expected capital expenditures and
predictions of slower growth in the second quarter. He blamed the drop
in Meta's ad business on the US war in Iran, as customers are spending
less on discretionary things like advertising. Zuckerberg attributes
the company's planned layoffs to a need to spend more on AI, and to
reflect the greater speed and efficiency AI brings to workflows.

 COPY FAIL: 732 BYTES TO ROOT ON EVERY MAJOR LINUX DISTRIBUTION (20
MINUTE READ) [10]

 Copy Fail is a logic bug in the Linux kernel's authencesn
cryptographic template that lets unprivileged users trigger a
deterministic, controlled 4-byte write into the page cache of any
readable file on the system. It can be exploited using a single
732-byte Python script to obtain root on essentially all Linux
distributions shipped since 2017. Its discovery was AI-assisted. A
patch for the bug is available.

 FIREFOX MAKER TORCHES GOOGLE FOR BUILDING PROMPT API INTO BROWSER (7
MINUTE READ) [11]

 Mozilla is against Google's decision to build AI plumbing into
Chrome. The Prompt API gives web pages the ability to directly prompt
a browser-provided language model. Mozilla says implementing the API
results in severe negative consequences to interoperability,
updateability, and neutrality of the web platform. The API is already
being tested in Chrome and Microsoft Edge.

 SILICON VALLEY IS BRACING FOR A PERMANENT UNDERCLASS (29 MINUTE READ)
[12]

 Many people in Silicon Valley believe that AI will soon surpass human
capabilities. While this should produce tremendous growth and
scientific achievement, it will displace millions of jobs, depress
economic mobility, and exacerbate inequality. The technology will
ferry power and wealth to the AI companies and existing owners of
capital while ordinary people lose their economic leverage. It could
create a permanent underclass as people are rendered useless and
unemployable.

Tu es l'extracteur de contenu de Breviat. On te fournit le contenu Markdown nettoyé d'une newsletter.

Ta mission : produire une version PROPRE du contenu en supprimant tout ce qui n'est pas de l'information utile au lecteur. Tu es un FILTRE, pas un résumeur.

À RETIRER :
- Publicités, encarts sponsors, mentions "sponsorisé par X", "ad", "présenté par"
- Intros vides : formules de bienvenue, météo de l'humeur de l'auteur, anecdotes personnelles non liées au contenu
- Appels à l'action marketing : s'abonner à la newsletter, parrainer un ami, "follow us on Twitter", "join our Discord"
- Signatures, mentions légales, adresses postales, "view in browser", "unsubscribe"
- Boutons / CTAs / "cliquez ici" / "lire la suite" sans contenu derrière
- Promotions d'autres produits / événements / formations payantes de l'auteur ou de tiers
- Encarts récurrents type "Read of the day" ou "Quote of the day" sans valeur informationnelle propre

À CONSERVER (intégralement, sans résumer ni reformuler) :
- Toutes les annonces, news, analyses, commentaires factuels
- Les chiffres, dates, noms d'entreprises, citations
- Les explications techniques
- Les liens vers des sources réelles (annonces officielles, papers, articles cités)
- La structure (titres, sous-titres, listes)

RÈGLES :
- Ne reformule pas. Garde la formulation d'origine.
- Ne résume pas, ne condense pas. Si une section fait 200 mots et est utile, garde 200 mots.
- N'ajoute aucun contenu (pas de titres ni de transitions de ton cru).
- Ne fabrique aucune URL. Garde celles d'origine, ou retire-les.
- Si la newsletter entière est de la pub / promo / contenu inutile, sors un Markdown vide (rien d'autre).

Sortie : UNIQUEMENT le Markdown nettoyé, sans préambule ni commentaire sur ton travail.
