An advert for Hire Yourself, a free self-employment contract generator from hired.wtf. It treats work as You, Inc.—one full-time slot you fill wherever you do your best work, with compensation set by you and reporting to yourself. Apply by naming a role (e.g., Chief Novel Completion Officer). The page shows mock recent hires and a 3-step process: apply, answer six questions to receive a formal contract, then sign. Free, no account, no watermark. Includes a tongue-in-cheek termination notice if you quit.

AdderBoard documents the smallest autoregressive transformer that can add two 10-digit numbers with ≥99% accuracy on 10,000 held-out tests. Solutions fall into hand-coded and trained weights, with a leaderboard of parameter counts and claimed accuracies. Tiny hand-coded models reach 36 params; trained models as low as ~311 params using rank-3 factorization, with d=4 or d=7 and ALiBi tricks. Core rules require a genuine self-attention Transformer, fixed input/output formatting, and 99% accuracy on 10k tests (seed 2025). Submissions are via GitHub issues or PRs; verification via verify.py.

An accessible overview of distributed systems, explaining how distance and independent failures shape design choices in data-center and internet-scale systems. It introduces core concepts—scalability, availability, latency, fault tolerance—and shows how abstractions and models (system, failure, and consistency models) guide tradeoffs. The text covers time, order, and clocks (Lamport and vector clocks), failure detectors, and the CAP theorem and FLP result. It then details replication patterns (partitioning, replication), strong-consistency protocols (2PC, Paxos, Raft, ZAB) and their limits, and weakly consistent approaches (Dynamo, CRDTs, CALM, PBS). It highlights read repair, gossip, Merkle trees, and reconciliation as ways to achieve convergence after partitions.

A synthesis on using otters as bioindicators of estuarine health, outlining scientific gaps, field-based insights, and a practical framework for future research and monitoring. The article argues otters reflect habitat quality due to their dependence on estuarine habitats, revealing insights on habitat connectivity, contaminant bioaccumulation across trophic levels, pathogen exposure and spillover, and behavioral/trophic proxies for ecosystem function. It surveys the global otter research landscape and proposes an operational framework for otter-based estuarine monitoring to guide future studies, policy, and management.

Cloudflare redesigned Turnstile and Challenge Pages to be clearer, more accessible, and consistent at scale. After auditing states, errors, and language variants, the team unified the information architecture, simplified error messages, and replaced "Send Feedback" with a Troubleshoot flow in a dedicated modal. They limited red to icons, improved readability to WCAG 2.2 AAA, and ensured multilingual support (40+ languages) with bidirectional layouts. Built in Rust for UI; tested with diverse users; kept the happy path intact. Measured impact via five metrics (CSR, time to complete, abandonment, ticket volume, social sentiment) and will iterate further.

Trump ordered all U.S. government agencies to immediately cease using Anthropic’s AI, with a six‑month phase‑out for agencies like the Defense Department, and warned of civil and criminal consequences. The Pentagon gave a 5:00 p.m. ET deadline for Anthropic to accept its terms or lose the contract, potentially labeling the company a "supply chain risk." Anthropic sticks to two redlines—no use for fully autonomous weapons and no mass domestic surveillance—while the latest Pentagon language could undermine safeguards. Senate leaders urge extended negotiations with Defense Secretary Pete Hegseth and Anthropic.

California's Assembly Bill 1043 requires OS providers to add an age-verification interface at account setup and to supply developers with a digital signal identifying the user's age bracket. Brackets: under 13, 13–15/under 16, 16–17/under 18, and 18+. Data must be collectable and shareable via an API, though facial scans or IDs aren't mandated. Enforcing this across all OSes (including Linux) is viewed as difficult, raising privacy and practicality concerns in broader age-verification debates.

OpenAI says a Chinese law enforcement official used ChatGPT as a diary to document a broad influence operation targeting Chinese dissidents abroad. The effort involved hundreds of operators, thousands of fake accounts, impersonating US immigration officials to warn dissidents, and forged documents to remove accounts. It included faking a dissident’s death and attempting to denigrate Japanese PM Sanae Takaichi. OpenAI banned the user after detection. The report shows how authoritarian regimes can harness AI for surveillance and information operations amid US‑China AI competition.

Rob Grant, co-creator of Red Dwarf and longtime Spitting Image writer, has died at 70. Tributes from Craig Charles and others praise his humor and legacy. Grant and Doug Naylor launched Red Dwarf in 1988; he later created The Strangerers and Dark Ages, wrote for Carrot's Lib, and authored novels, including Titan, co-credited to Andrew Marshall and slated for July publication. Cause of death has not been released. Bruce Dessau reported for Beyond The Joke on 26 February 2026.

Apple’s Sleep Indicator Light, the breathing light, debuted with the iBook G3 (1999) and later appeared on iMacs and Power Macs. The green LED was replaced by a white one; the pulsating 12 breaths-per-minute animation was designed to feel comforting. A light sensor on the iMac G5 dimmed the glow in dark rooms, and later MacBooks eliminated the opening, with the aluminum perforated to imply light emanating through. An unadvertised feature synced the display’s sleep light with the Mac’s. By the 2010s breathing light disappeared, and the author laments its loss as a meaningful detail that signaled safe sleep.

DOS memory management is simple but often counterintuitive. DOS 1.x had no explicit management, fitting RAM near 64K; DOS 2.0 added per-process memory with an arena of MCB-described blocks, sized in 16-byte paragraphs. Each block has an MCB header with signature (M/Z), owner (0 free, else PSP/PID), and size. Blocks are chained by position, not pointers. Allocation uses ALLOC; deallocation uses DEALLOC; resizing uses SETBLOCK. Coalescing occurs during ALLOC and via SETBLOCK; DEALLOC does not. DOS 2.11 added AllocOper (first/best/last fit). DOS 5.0 added UMB support with dual arenas and enhanced AllocOper for UMBs.

Browser Use built a secure, scalable agent sandbox for web agents. They moved from Lambda-based bots with code execution to Pattern 2 isolation: the entire agent runs in a sandbox, while a control plane holds credentials and proxies all outside calls. Production uses Unikraft micro-VMs; development uses Docker. Hardening: bytecode-only execution, privilege dropping, environment stripping. The stateless control plane validates tokens, handles LLM calls, and storage via presigned URLs; sandboxes have no AWS keys. Scaling uses ECS Fargate for the control plane and distributed Unikraft sandboxes. Takeaway: the agent should have nothing worth stealing or preserving.

Left Google in early 2026 after Google added AI features to search and Gmail; switched to Proton and other services. Argues Google's presence is habit-driven, search quality is worse, and Brave and DuckDuckGo outperform Google for over 90% of searches. The move rekindled 'surfing the web' instead of 'Googling,' improved digital hygiene, and reduced ads and privacy intrusions, though YouTube remains due to lack of real alternatives. Highlights open-web benefits and urges others to quit Google.

An in-depth look at sandbox isolation layers, arguing that isolation is a boundary, not a binary. Namespaces are visibility walls; cgroups handle accounting; seccomp filters syscalls but still exports to the host kernel. Privileged mode undermines security. gVisor introduces a user-space Sentry kernel, shrinking the host attack surface (~70 host syscalls) and enabling defense-in-depth within a sandbox. MicroVMs deliver hardware-bound isolation with snapshotting; WASM offers kernel-free, memory-safe execution but limited language support. The piece stresses layering (per‑job namespaces, seccomp, privilege drops, ephemeral storage, network controls) and considers local dev sandboxes (Seatbelt/Landlock) and Apple's container VM approach as evolution.
