Post-quantum crypto in orbit - Borealis, a pure OCaml CCSDS stack, reportedly booted in low Earth orbit with BPv7 + BPSec and post-quantum OTAR using ML-DSA-65—highlighting memory safety and key management in space.

Local LLM selection and tooling - Two local-AI stories: whichllm ranks models based on real hardware constraints and benchmark freshness, while DwarfStar 4 signals an inflection point where near-frontier quality may be practical on high-end local machines.

Open source faces vulnerability flood - Metabase warns LLM-assisted security scanning is sharply increasing vulnerability report volume and quality, changing responsible disclosure timelines and pushing maintainers toward faster patching and stronger dependency hygiene.

Connected car privacy hardware mods - A Toyota owner removed the cellular modem and GPS to stop telemetry, illustrating the privacy vs. safety tradeoffs of connected vehicles and raising right-to-repair and data-collection concerns.

UK replaces Palantir refugee system - The UK government says it saved millions by replacing a Palantir Foundry-based platform with an in-house system for the Homes for Ukraine program—fueling the debate over procurement, lock-in, and “sovereign tech.”

Wikipedia as a file explorer - Wikipedia File Explorer reimagines Wikimedia browsing as a desktop-style folder system, making discovery more intuitive while revealing gaps in categorization and metadata.

Steve Jobs, NeXT, and Apple - An IEEE Spectrum interview argues Steve Jobs’ NeXT years shaped Apple’s later success, and frames those lessons against a rumored Apple CEO transition and the company’s positioning on AI.

Post-quantum crypto in orbit
In space and security news, an OCaml implementation of parts of the CCSDS space communications stack—codenamed Borealis—has reportedly booted and started operating in low Earth orbit aboard DPhi Space’s ClusterGate‑2 hosted payload module. The interesting angle isn’t just “a new protocol stack in space.” It’s the security posture: Borealis treats its communications link like a delay‑tolerant network, wrapping traffic into BPv7 bundles, and protecting it with BPSec encryption and authentication.

Why does that matter? Hosted payloads are essentially multi‑tenant compute in orbit. If you’re running alongside other software on shared satellite hardware, you have to assume isolation can fail—especially when Linux kernel privilege escalation and container escape bugs keep showing up, and patching in orbit is slow, risky, or sometimes impossible. The project is betting that memory-safe OCaml plus strong cryptography reduces the blast radius if anything goes sideways.

And the headline-worthy claim: Borealis includes over‑the‑air rekeying for long‑lived post‑quantum signing keys—specifically ML‑DSA‑65. If this is indeed the first publicly described in‑orbit post‑quantum OTAR demo, it’s a meaningful marker that “future-proof” crypto isn’t just a lab exercise anymore—it’s being tested where recovery is hardest: in space.

Staying with the “secure software meets real-world constraints” theme, the Borealis author also previewed a planned move to Jane Street’s OxCaml to reduce latency jitter on packet dispatch paths. Tha...
