Website revamp, HSP + Cattle Logic on the App Store, PCS certificate management merged — against a 92K-layoff backdrop
arkashj.com revamped (UROP, changelog, stack icons, Benmore link, sitemaps submitted to Google + Bing), HSP and Cattle Logic both shipped to the App Store, the PCS certificate management system merged, and Titov was given devs on PCS — all while the macro tape read 92K tech layoffs, Anthropic at $1T, OAI at $880B, and Codex 5.5.

Hiring kickoff, Latinovation, Legora culture, and mech-interp via Kalman + PCA
PCS PR queue cleared across five threads (Trevin, Brad & Eddie, Propurti, PCS checks, ongoing dev), Chantal intelligence-tab handed off and Monica research kicked off, Alex Titov starting Monday, hiring conversations opening with Martins via Trueup + Builtin, and a reading week on Legora's lean Stockholm culture, mechanistic interpretability via Kalman filters + PCA, the Karg port endgame, and Nvidia carving 20% of die area for Groq while positioning Vera CPU for agentic + RL workloads.

PCS hardening week, Anthropic's J-curve, ERCOT vs PJM, and the silicon shortage
PCS audit logging + Kong gateway + JWT hardening, CRL/Workforce shipped, four new engineers onboarded (Jacob, Leo, Aditya, Enrin), and a deep reading week on the AI silicon shortage, Anthropic's 12× ARR jump, ERCOT vs PJM capacity markets, and the SEC/CFTC split on tokenized securities.

SpatialDINO: Self-Supervised Learning for 3D Vision Transformers
Arkash Jain et al. (Kirchhausen Lab, Harvard Medical School)
A 3D self-supervised vision transformer for label-free segmentation and tracking of subcellular dynamics in lattice light-sheet microscopy (LLSM). Beat a prior approach co-led by Nobel laureate Eric Betzig on downstream subcellular structure prediction.
Read paper →Close-up of Vesicular ER Exit Sites by Volume Electron Imaging using FIB-SEM
Kirchhausen Lab
Volumetric reconstruction of mammalian ER exit sites at unprecedented resolution via FIB-SEM and learned segmentation.
Read paper →Ultrafast 2DIR comparison of rotational energy transfer, isolated binary collision breakdown, and near critical fluctuations in Xe and SF6 solutions
