Easel unveils a custom physics engine built for incremental rollback: it snapshots and rolls back only the parts of the world that change each frame, enabling large multiplayer worlds (thousands of objects) by typically affecting maybe 30 objects per frame. Key features include immediate sleep for resting bodies, an optimized BVH with category tracking, non-bouncy stepping via ForcefulStep and restitution=0, and a CCD approach that resolves collisions before time-of-impact. Bodies can move even without colliders. It leverages Parry-based collision detection and enables bigger, more dynamic Easel games.

The post argues harness for multi-user should run outside the sandbox. Inside vs outside: inside is simple but hard to share; outside runs on backend with credentials out of sandbox. They chose outside for security and shared state. Durability with Inngest; Blaxel sandbox resume 25ms. Filesystem: skills/memories in database, workspace in sandbox; shared state without distributed FS. Avoid extra tools to prevent prompt bloat. Challenges: evolving patterns, consistency; last-writer-wins per key; guardrails. They advise AI DevOps.

A new study published in Science Advances shows Neanderthals at Neumark-Nord 2 in central Germany, 125,000 years ago, not only breaking bones for marrow but fragmenting hundreds of large mammal bones to render fat by cooking in water. The site yielded evidence of at least 172 large mammals processed and a central bone-grease rendering area, indicating intensive, planned resource management. This suggests Neanderthals organized hunts, transported carcasses, and used fat strategically, revealing sophisticated ecological engagement earlier than previously thought.

David Smith chronicles six years of building the best watchOS map for Pedometer++. Early experiments used server-rendered maps, but he later built a SwiftUI-native, tile-based engine enabling offline rendering with overlays. Design repeatedly grappled with the tiny, one-handed screen, settling on a modal layout that separates map browsing from metrics and avoids swipe-heavy UI. With watchOS 26 and Liquid Glass, he commissioned a cartographer to create a custom, high-contrast basemap and a dark-mode variant. A collaboration with Rafa Conde produced the final layered design; he explains why he rejected MapKit for greater configurability.

After years of self-hosting Bitwarden, I no longer recommend it. The vendor’s open-source narrative clashes with venture-backed priorities, licensing changes (SDK), and a heavier, enterprise‑oriented backend. Migration/import issues, UX flaws, brittle client updates, and repeated security incidents (2023 KDF flaws and Windows Hello bypass, 2023 cross-origin autofill, 2025 DOM-based clickjacking, 2026 CLI supply‑chain compromise) cement my view. I now split secrets by use-case: A) client‑work SaaS manager, B) separate cloud-based for PII, C) KeePass with Syncthing, D) Vault/Infisical for infrastructure, E) pass for one-offs.

This pull request enables AI co-author trailers by default in the Git extension for VS Code by changing git.addAICoAuthor from 'off' to 'all'. It causes Co-authored-by trailers to be added automatically for AI-generated contributions. The change also revealed a runtime-default mismatch (fallback still uses 'off'), prompting calls to align defaults or revert. The community reacted with strong criticism for silently changing behavior without user notification, with push to revert and require explicit opt-in.

Frustrated by Bolt v3 sync issue, reverse engineered its Android app. They found profile system: STD, BETA, ALPHA, DEV, FACTORY; setting DEV unlocks Debug Menu under Settings. The profile lives in SharedPreferences; changing it needs ADB (ALPHA+). The BLE port BOLT_CFG exposes binary protocol; to unlock DEV, send three bytes: 0x01 0x42 0x03 (SEND_PREFS, APP_PROFILE=66, DEV=3). A Python script using bleak automates this after subscribing to notifications. Reboot shows the Debug Menu and “WELCOME TO HELL DEVELOPER,” with config viewer, GPS controls, logs, crash, and reset; DEV mode adds ADB and a web server. The issue was on phone.

The piece argues print culture isn’t dead but resurging through new and revived little magazines. It notes recent print revivals—The New York Sun’s return to weekly print in 2025, News Corp’s California Post, County Highway, Saveur’s return to print, and Field & Stream’s comeback—that form backdrop for Portico, a quarterly edited by Micah Mattix. Portico, launched under the Institute on Religion and Public Life, showcases literary work (jazz, Cowley, a Helprin story, formalist poetry) and signals a renewed interest in 'little' magazines. The author recalls how print shaped his education and hints at a second golden age.

Proposes a universal DO_NOT_TRACK environment variable to opt out of ad tracking, usage analytics, telemetry, crash reporting, and non-essential requests across software. The problem: many CLI tools use disparate opt-out flags, e.g., .NET DOTNET_CLI_TELEMETRY_OPTOUT=1, SAM_CLI_TELEMETRY=0, AZURE_CORE_COLLECT_TELEMETRY=0, GATSBY_TELEMETRY_DISABLED=1, gcloud, Homebrew, Netlify, Syncthing. The proposal: set DO_NOT_TRACK=1 in shell config (bash, zsh, fish) or PowerShell/Windows. Software authors should respect DO_NOT_TRACK=1, disable tracking accordingly, and consider telemetry opt-in. See also NO_COLOR and FORCE_COLOR.

rANS encodes a symbol sequence into a single integer using reversible arithmetic. For symbol s with frequency f_s, cumulative c_s, and total M, the encoder updates x to x' = floor(x/f_s)*M + c_s + (x mod f_s). The decoder recovers s and the previous x from x' by inspecting x' mod M and the symbol’s range; it’s the inverse process. To keep x bounded, renormalization spills digits to an output stream. Encoding processes input in reverse; decoding runs forward, giving a last-in-first-out (LIFO) behavior. Efficient, near-constant per-symbol work with a slot table.

Flue is an agent-harness framework that composes a Model + Harness to build autonomous agents. Write TypeScript workflows once and deploy anywhere—from HTTP servers or CLIs to CI pipelines—using various sandboxes (built-in, just-bash, Daytona, Cloudflare Workers, etc.). Agents run skills, manage sessions, issue prompts, and execute shell commands with token safeguards. The platform supports diverse roles (issue triage, data analysis, coding, customer support) and shows integration with tools like GitHub. Flue emphasizes owning the full stack and easy, flexible deployment of powerful, programmable agents.

C3 historically used unsigned sizes by default (isz/usz), but unsigned arithmetic caused loops that don’t terminate, unsafe comparisons, and subtle wraparound bugs in indexing and math. Casts could hide warnings, but implicit unsigned/signed conversions were problematic. The article argues signed sizes offer clearer semantics and fewer surprises, and describes moving to a default signed size (sz), renaming isz to sz and strengthening the sz/usz pair, with the change nicknamed szmageddon. The change, inspired by Go and Java, simplifies reasoning and improves correctness across the codebase.

California's DMV unveiled stricter autonomous vehicle regulations that let police issue tickets to AV manufacturers for moving violations. The rules, which take effect July 1 as part of 2024 legislation, require AV companies to respond to law-enforcement calls within 30 seconds and impose penalties for entering active emergency zones. DMV calls them the nation's most comprehensive AV rules. With Waymo and Tesla among operators, incidents like a Waymo illegal U-turn in San Bruno and widespread robotaxi congestion during a San Francisco blackout highlighted enforcement gaps before these measures.
