Most of this Silicon Valley network in AI is also Epstein's network. It's not just women and girls who are groomed and abused by these men. Perhaps a death and sex cult shouldn't be left to self regulate tech products. We need accountability and justice.

Imagine being lowered into a gas chamber while fully conscious. The gas causes pain as it dissolves into the moist tissues of your eyes, nose, mouth and lungs. Breathing becomes extremely painful. And you may remain conscious for up to 60 seconds before finally blacking out.

🇵🇸 More than 70 children are among 100 Palestinians being laid to rest in Gaza today after their bodies were recovered from beneath their homes’ rubble, Dr. Muneer al-Bursh, director general of Gaza’s Health Ministry writes on X. Families waited two years, some longer, to bury them.

More than 8,000 people remain missing under the rubble, he says. Israel continues blocking heavy machinery needed to recover bodies, according to civil defense teams. Al-Bursh called for Israel to stop blocking rescue equipment, forensic supplies, and DNA testing to identify the dead.

He also accused Israel of mixing human remains with rubble, warning that this risks destroying evidence. In the southern city of Rafah, he said, bones have become mingled with debris. He urged action before Israel could conceal evidence of its crimes.

“Every set of remains bears a name, and every name a family that waits.”
Dr.Muneer Alboursh د.منيرالبرش
@Dr_Muneer1
Translated from Arabic
Seventy Children in One Funeral… This Is What Genocide Looks Like

Today, Gaza lays one hundred martyrs to rest, more than seventy of them children, whose bodies were pulled from beneath the rubble of their homes after years.

These children should have been carrying their schoolbags to school, playing and growing and dreaming… not being carried from beneath the rubble to their graves.

They were not numbers; they were names and faces and little dreams, and mothers and fathers who waited far too long to bid their children farewell.

When children form the majority of a funeral of this size, the question becomes agonizing:

If this is not one of the faces of genocide, then what does genocide look like?

Gaza today is not only burying its children…
It is burying dreams that should have grown.

ah yes, the Nobel prize winning algorithm. the gale shapley algorithm. the algorithm that produces the best result for the proactive party and the worst result to the people in the receiving end.
Hinge is built on the belief that anyone looking for love should be able to find it. It’s also built on an acclaimed Nobel-Prize-winning algorithm, so we can succeed in getting you out on promising dates, not keeping you on the app.There may be many stable matchings for the same system of preferences. This raises the question: which matching is returned by the Gale–Shapley algorithm? Is it the matching better for applicants, for employers, or an intermediate one? As it turns out, the Gale–Shapley algorithm in which employers make offers to applicants always yields the same stable matching (regardless of the order in which job offers are made), and its choice is the stable matching that is the best for all employers and worst for all applicants among all stable matchings.[11]

Life is full of things that, by complexity or design or lack of care or required time, are hard to navigate: healthcare, government, personal finance, school forms are all among them It is why I feel consumer AI is underrated. People muddle by, but are missing support & AI is good enough to help.

Quasipolynomial Cryptanalysis of the McEliece Cryptosystem (or: PIR Meets McEliece) (Ashrujit Ghoshal, Yuval Ishai, Aayush Jain, Nuozhou Sun) ia.cr/2026/1630
Abstract. The McEliece code-based cryptosystem, utilizing binary Goppa codes, is the earliest public-key encryption scheme that is still considered post-quantum secure. We present a simple, classical quasipolynomial-time distinguisher for Goppa–McEliece in the asymptotic “Classic McEliece” regime: for code length n, extension degree m = Θ(log n), Goppa degree t = Θ(n/log n), and public-code dimension k = Θ(n), the algorithm runs in time n^(𝒪(log n)) and distinguishes the McEliece public key from the uniform distribution over 𝔽₂^(k × n) with advantage 1 − o(1). The distinguisher is not merely asymptotic: it applies to all Classic McEliece parameter sets considered in the NIST process and yields improved (though not yet practical) concrete attack estimates.

Our distinguishing attack originated from a failed attempt to construct doubly efficient private information retrieval (PIR) protocols from algebraic locally decodable codes, and can be intuitively explained from the PIR perspective. We extend this provable algorithm to a heuristic n^(𝒪(log n))-time ciphertext-decryption attack that recovers the message from a noisy codeword.
