Good news everyone, I've created an advanced AI that can replace 90% of the managers in tech companies:

Just released mori 0.1.0 on CRAN β€” a new R package for sharing R objects across processes via OS-level shared memory.

Parallel R today duplicates your data in every worker's RAM. 8 workers Γ— 1 GB = 8 GB. mori puts it in shared memory once; every worker maps the same physical pages via R's ALTREP framework.

Works with any parallel backend that uses R's standard serialization, including mirai, parallel and callr.

mori: Shared memory for R objects

mori is a new R package for sharing R objects across processes via OS-level shared memory. Parallel workers get zero-copy, lazy ALTREP access to the same physical pages β€” share once, read anywhere.

The evaluation of #Anthropic #Mythos by #AISI #UK, does not seem to demonstrate the super-cracking ability mentioned elsewhere. It is noted its specific ability to chain attacks.

Our evaluation of Claude Mythos Preview’s cyber capabilities | AISI Work

We conducted cyber evaluations of Anthropic’s Claude Mythos Preview and found continued improvement in capture-the-flag (CTF) challenges and significant improvement on multi-step cyber-attack simulations.

I have an unfounded theory that in #Peru we are low key training people to do complex estimations and take multidimensional decision, otherwise why have 35 different parties, and have to cast 5 distinct votes in today's #election: president, national senate, regional senate, deputies (congress representative for the #USA folks), and Andean Parliament. And then we got preferential votes.

The voting ballot was huge (see the models here https://eg2026.onpe.gob.pe/cedula/descarga-tu-cedula/ with made up parties).
