Long-lived cryptographic keys are liabilities that accumulate risk over time as people leave and attackers guess credentials. Ephemeral keys—valid for short periods—avoid much of the rotation pain. Replace long-lived SSH keys with temporary credentials; use trusted publishers instead of static PyPI tokens; leverage SSO to replace user passwords with short-lived assertions, while signing keys remain long-lived. If possible, reduce the number and scope of long-lived keys, set tight maximum lifetimes, rotate at least quarterly, and centralize maintenance to a focused team. This strengthens security and reduces operational toil.

FusionCore is a ROS 2 sensor-fusion SDK (Apache 2.0) that fuses IMU, wheel odometry, and GPS into a single 3D position/pose estimate using a 22D state Unscented Kalman Filter with native ECEF/GNSS support and auto-tuned noise. Key features: automatic IMU bias estimation, zero-velocity updates (ZUPT), Mahalanobis-outlier rejection, adaptive noise covariance, delay compensation with 1s IMU replay, per-sensor diagnostics, GNSS lever-arm handling, and heading observability guards (dual antenna, IMU orientation, GPS track). Outputs /fusion/odom and /fusion/pose at 100 Hz; ROS 2 Nav2 integration; PROJ CRS support; Gazebo simulation; Apache 2.0.

Lightwhale 3 is a minimal, container-first OS that boots from an ISO into a working Docker Engine with no installation. Its root is immutable, reducing maintenance and attack surface; a writable data filesystem (RAM by default) can be enabled on a separate device to persist changes. Persistence uses a magic header to assemble a Btrfs volume and overlay writable dirs (/etc, /var, /home). Docker data lives on the data filesystem. Works on x86-64 bare-metal or VMs; not Raspberry Pi. Privacy-friendly; optional anonymous telemetry. Default login: op/opsecret.

HNswered is a small Chrome side panel for Hacker News replies. It watches the public stories and comments you authored and surfaces direct replies in a local inbox with unread/read filters. It keeps state in Chrome storage and works without any login, server, or backend—using only public HN data matched locally. The repo ships a pre-built dist for easy installation; building from source is only needed for contributors.

MiniZinc announces open problem submissions for the 2026 MiniZinc Challenge. The page promotes MiniZinc as a high-level, solver-independent constraint modelling language for discrete optimization, with an IDE, extensive docs, and the ability to embed in Python/JavaScript or run in-browser. It advertises Map coloring, N Queens, rectangle packing, Sudoku, and rostering/vehicle routing examples. The latest release is MiniZinc 2.9.6 (April 24, 2026) with Xpress migration, SCIP 10 support, new count_* constraints, a --cleanup-time-limit option, and 15 bug fixes. MiniZinc is developed at Monash University with OPTIMA funding.

TIPSv2 advances vision-language pretraining by showing distillation yields superior patch-text alignment and introducing three improvements: iBOT++ extends the patch-level self-distillation loss to all tokens (masked and visible); Head-only EMA reduces training parameters by 42%; and Multi-Granularity Captions adds richer Gemini and PaliGemma captions for supervision. A distilled ViT-L student from a ViT-g teacher strongly surpasses its teacher in zero-shot segmentation. Across 9 tasks and 20 datasets, it matches or exceeds recent encoders and yields smoother, more precise feature maps.

Matt May built Driggsby, a Plaid-backed MCP server that exposes balances, transactions, and investments via tools. Using Claude Code routines, he shifted from manual queries to autopilot: a daily financial overview email. A Gmail limitation (drafts only) led to a custom email_me() tool for secure emails in Markdown with CSS. After initial hiccups (2FA, format changes), routines were refined: weekly anomaly checks on Amex transactions, daily large-outflow alerts (> $500), and expansion to investments and subscriptions. Claude Code routines make cloud automation with personal data easy and customizable for both partners.

After buying a Rodecaster Duo for mic setups, the author explored its firmware update. They found two partitions, no firmware signature checks, and SSH with pubkey authentication enabled by default (keys included). Using macOS tools and Windows USBPcap, they mapped the flow: the RodeCaster App sends M to enter update mode and U to flash; archive.tar.gz and archive.md5 are copied to the exposed disk and flashed on reboot. They even enabled SSH with password auth and their key via a container to flash. The process was surprisingly easy; they filed a ticket with Rode and remain impressed.

Google plans to invest up to $40 billion in Anthropic in cash and compute—$10 billion upfront at a $350 billion valuation, with up to $30 billion more if performance targets are met. The deal expands Anthropic’s access to Google Cloud TPUs and adds five gigawatts of compute capacity over five years, with room to scale. Anthropic’s Mythos, its most powerful model, has cybersecurity applications but is restricted due to misuse risks. Google stays a major AI infrastructure supplier amid a broader compute race with Amazon, CoreWeave, and others.

Library of Congress post 'The Classic American Diner' surveys photographs that document the era’s diners— their streamlined, railcar-like exteriors, 24‑hour service, and mid‑century menus. It highlights trucker customers and regional variations, with examples across the United States: a 1982 Columbus, Georgia diner (American and Korean fare); the Country Girl Diner in Chester, Vermont (2017); 1940 Berwyn, Maryland (hot dogs for 5 cents); 1959 New York City (ham and eggs); 1941 Cortland, New York (truckers); 1943 Aberdeen, Maryland (truckers). Later images revive nostalgia at Sunliner Diner (2021) and 5 & Diner Phoenix (2018). Readers are invited to explore more in the Highsmith Archive and LOC.

cc-canary is a drift-detection tool for Claude Code. It scans local Claude logs (reads ~/.claude/projects/**/*.jsonl), detects model drift in your own work, and runs offline (no network, account, telemetry, or daemon). It generates shareable forensic reports in Markdown/HTML, with a verdict (HOLDING, SUSPECTED REGRESSION, CONFIRMED REGRESSION, INCONCLUSIVE), headline metrics, weekly trends, cross-version comparisons, and inflection thinking-depth analyses. Default window is 60 days (configurable 7d–180d). Output: cc-canary-<date>.{md,html}. Install: npx skills add delta-hq/cc-canary --skill cc-canary; or --skill cc-canary-html for HTML dashboard.

Castillo used BigQuery’s Hacker News data and Claude to track arXiv links, finding arXiv posts on HN have fallen recently; 2019’s top arXiv stories were dominated by deep learning. Top-100 upvoted papers: 2019—41% DL; 2023–2026—59% LLM/AI. Notable 2019 papers that aged well: MuZero, EfficientNet, XLNet, PyTorch, On the Measure of Intelligence. For 2023–2026, likely enduring works include DeepSeek-R1, Generative Agents, The Era of 1-bit LLMs, Differential Transformer, and LK-99 cluster (a meta-science, crowdsourced replication lens).

Recurse Center redesigned its application to better convey what it’s like to be a Recursers and attract curious, self-directed programmers. Inspired by the Oxford All Souls exams, they replaced the old form with two questions from a new, alumni-crafted set, plus a prompt about a programming project they’re proud of. Questions invite storytelling and reflection (e.g., the weirdest bug, is code math or literature, explain something simply). They stress a clear rubric, engaging applicants without being long, and use weekly reviewer sessions to gauge fit and curiosity.
