I remember studying this fact: The first BASIC program successfully executed at 4 am on May 1, 1964, on a General Electric GE-225 mainframe.

BASIC launched on this day in 1964.

I wondered if this might be coming – you can only let LLMs hit your program like a piñata for so long before you reduce the amount of candy that pops out on each whack

Big changes to Android and Chrome VRP: - focus on high-impact, reproducible bugs with low/no reward for lower impact - big prizes for full chains with some annual limits - PoCs required It’s the end of an era, but the start of a new one. bughunters.google.com/blog/evolving-…

El Ministerio en contra de la postura formal del Relator de Naciones Unidas para los Derechos Fundamentales donde deja meridianamente claro que el anonimato y el cifrado son esenciales, por ejemplo, para la protección de los colectivos en riesgo de exclusión.
El "gobierno más progresista" en contra de los Derechos Humanos.

Nice writeup on LLM-driven reverse engineering and countermeasures. My own experiments are aligned with these findings: classic transformations are easily breakable, but there is room for developing obfuscation techniques tailored to LLMs.

I too woke up and choose violence today as the fail-copy POC dropped.
Made a clean exploit including fixing the UID post exploitation without rebooting the target server. Smoke those CTF’s in hack the box.

I converted the #fast16 patch engine instructions to human-readable to get a better understanding what exactly is being done
It's a pretty nifty engine:
- wildcards
- patterns can depend on other patterns
- scratch space
- fixup instruction
Full list:

1) En 1934, un anciano David Hilbert cenaba con Bernhard Rust, ministro de Educación nazi. Rust le preguntó cómo iba la matemática en Gotinga ahora que estaba "libre de la influencia judía". Hilbert, protagonista de una de las búsquedas científicas más estimulantes del siglo, le respondió lacónicamente: "Ya no hay matemática en Gotinga."
Para empezar a entender esa frase hay que saber qué era Gotinga. Y desgraciadamente, tenemos que hablar en pasado. Durante más de un siglo, la pequeña ciudad de la Baja Sajonia fue uno de los grandes centros de la matemática mundial. Gauss, Riemann, Hilbert, Noether o Born pasaron por allí. Libertad académica, financiación estable y prestigio social del saber. Uno de los ecosistemas más productivos para la innovación intelectual que jamás hayan existido, destruido de un plumazo por los nazis. Y todavía leo de vez en cuando eso de "fueron unos monstruos, pero económicamente levantaron Alemania..." 🧵

Last night Ben Sasse confirmed my suspicion that Dr. Santiago Schnell, provost at Dartmouth, is quickly becoming the single most influential voice in higher education. If you haven’t already read his essay on AI that broke the internet you should.
“AI has not created new educational problems; it has made old ones impossible to ignore. The habit of rewarding performance over understanding, fluency over depth, and polish over genuine engagement was already present in our institutions before the first language model was trained. AI simply industrializes and accelerates those habits until their emptiness becomes undeniable…”

doing this in 2026 just means malware silently downgrades the model for every AI agent and sets effort to low fleet-wide.
inside an AI lab, nobody would notice until the graphs somehow got worse.

A newly decoded piece of sabotage malware called Fast16, created before Stuxnet, was made to silently tamper with calculations in research and engineering software. Likely created by the US or an ally, and possibly used against Iran's nuclear program. wired.com/story/fast16-m…
