Tooling pass — Biome, Knip, Zustand, TanStack Query, and three backfilled weekly entries
Cleaned up the dev toolchain (added Biome + Knip alongside ESLint/Prettier), introduced Zustand for cmdk/mobile-nav state, wrapped the admin/weekly form in TanStack Query, purged ~14 dead files + ~1k LOC via Knip, refreshed the architecture map with a new client-state diagram, and backfilled three earlier weekly entries (W11, W12, W17) that never made it to the site.

KKR/FSK at NAV, SpaceXAI, and the EDA Primer — three primers on capital, compute, and silicon
Matt Levine on KKR's $300M FS KKR injection (half preferred-at-NAV, half tender-at-discount), the Virginia redistricting referendum that broke Kalshi's resolution rules, and OpenAI's $30M-per-head employee tender. Ben Thompson on the Anthropic-SpaceXAI deal and AI as a deployment-company business. SemiAnalysis's 13-stage RTL-to-silicon primer.

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.

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
Arkash Jain et al.
