mahler.c is a lightweight C99 library for Western music theory. It provides interval, chord, scale, and key-signature functions with no internal memory allocation, enharmonic correctness, and support for theoretical keys. The project includes examples (e.g., generating the C4 Blues Scale), unit tests (100% coverage), and documentation. Build via CMake (requires 3.10+), including src/inc paths and linking against the mahler library. It's MIT-licensed, aimed at simple, portable music-theory tooling in C.

Four years in startup infrastructure: AWS favored for support and stability over GCP; Kubernetes via EKS with Helm replacements for addons; RDS and Redis praised; ECR stable; VPN simple with Okta; Terraform over CloudFormation; Atlantis for Terraform automation; Flux 2 for GitOps; Karpenter for cost-effective autoscaling; ExternalSecrets, ExternalDNS, cert-manager for secrets/DNS/certs; Renovatebot for dependency updates; Nginx ingress; Notion/Slack/Linear for docs/communication; monthly cloud-cost reviews; OpenTelemetry early adoption recommended; regrets include Datadog pricing, SealedSecrets, Bottlerocket networking issues, limited FaaS, and delayed identity platform upgrade (Google Workspace).

Adds lightweight type-based alias analysis (TBAA) to the Toy Optimizer to improve load-store caching. A hierarchical heap-type model (Any -> Object -> Array/String/Other) assigns each region a [start, end) range, making aliasing a range-overlap test. May_alias compares ranges, defaulting to Any when missing. This lets the optimizer distinguish accesses by type and lets a test where stores to Array and String offsets don’t invalidate each other pass. The post also covers object provenance (allocation sites) to further limit aliasing, partial invalidation via known builtins, and a precision–speed tradeoff useful in JITs.

Stanford researchers report a nasal "universal vaccine" that could defend against many respiratory infections—flu, Covid, colds, and even certain bacteria and possibly allergens. Tested in animals, it doesn’t train for one pathogen; it primes lung macrophages to stay on "amber alert," reducing viral entry 100–1,000-fold for about three months. Delivery may require a nebuliser to reach deep lungs. Human trials are not yet done; experts caution about immune over-activation but call it an exciting potential step to complement existing vaccines.

An accessible beginner guide to split keyboards, outlining why splitting reduces wrist/shoulder strain, and mapping the landscape from row-staggered to columnar and ortholinear layouts. It presents two paths—quick split setups for minimal relearning and deeper dives for ergonomics—then covers features (keys, geometry, tenting, pointing devices, encoders), wired vs wireless, switches, and extensive keymap customization. It also addresses non-QWERTY layouts, choosing a model, buying vs DIY (from ready-made to open-source designs), popular boards, and testing through prototypes, with health tips about breaks.

cmux is a native macOS terminal app (Swift/AppKit) that combines a Ghostty-based terminal with vertical tabs and a notification system for AI coding agents. It renders terminals fast with libghostty, reads Ghostty configs, and adds a sidebar showing workspace details and latest notifications. It supports an in-app browser, split panes (terminal and browser), and a scriptable CLI/socket API to manage workspaces, tabs, and actions. Notifications highlight waiting agents; a CLI command cmux notify hooks into Claude Code/OpenCode workflows. Install via DMG or Homebrew; licensed AGPL-3.0-or-later.

Trump-era cuts to NIH/NSF funds throttle US science, triggering a brain drain that imperils America's biomedical leadership. The piece cites billions cut, thousands of grants canceled, and more than 1,000 NIH staff fired, leaving labs unable to maintain equipment or hire researchers. Early-career scientists like Ian Morgan face halted lab startups and rising uncertainty; hundreds are leaving for Europe, Australia, and Asia as European programs recruit “scientific asylum.” Training programs dried up, visas tightened, and the US risks losing its next generation of discoveries and economic growth.

Level of Detail (LoD) in 3D rendering—render only what the viewer can discern; as you get closer you swap in higher detail, streaming and culling to avoid waste. The essay maps this to software work: we use low-LoD models to think and debug, abstracting away internals while preserving the silhouette. With LLMs, context is the LoD: too little or too much harms quality; load the right level for the task. AI can generate code rapidly, but the value lies in architecture and pruning—deciding what to keep matters most, especially for the user-facing component.

Gita Jackson argues the idea that the left hates technology is false: leftists love useful tech but resist how capital exploits workers through AI. She critiques hype around AI from Anthropic and OpenAI, notes debates about “understanding” rely on academic terms, and maintains AI is essentially next-token math. The piece contends tech adoption mainly benefits owners, not workers (e.g., rideshares); it rejects techno-optimism and calls for solidarity and Marxian redistribution over flashy promises.

Stop Thinking of AI as a Coworker. It's an Exoskeleton argues that AI works best when treated as a human-augmentation tool, not an autonomous agent. By comparing AI to exoskeletons in manufacturing, military, and medicine, the piece shows how amplification, not replacement, boosts performance and reduces injury. It warns autonomous agents fail due to lacking enterprise context, then presents Kasava’s exoskeleton approach: a product graph that fuses automated signals from code, commits, and user input with human judgment. Build micro-agents, keep humans in the loop, and reveal system seams. The future is amplified, not autonomous.

Google unveils Gemini 3.1 Pro, a smarter model for complex tasks. Building on Gemini 3 Pro, 3.1 Pro boosts core reasoning (ARC-AGI-2 score 77.1%, more than double 3 Pro) and is rolling out in preview to developers, enterprises, and consumers. Access is via the Gemini API, Google AI Studio, Gemini CLI, Google Antigravity, Android Studio; Vertex AI and Gemini Enterprise for business; and the Gemini app and NotebookLM for consumers. It supports advanced problem solving, data synthesis, API integration, and creative coding (e.g., SVG animations, interactive dashboards, generative interfaces). Plans call for broader availability after validation.

Harry McCracken chronicles turning Arctic Adventure, his 1981 TRS-80 BASIC text game, into Arctic Adventure 2026 using Claude Code. After a 2021 web release, he dumped the original BASIC listing into Claude Code, producing a playable web edition with graphics, animations, and five-saved games, plus an undo death, clickable interactions, and a text-only option. The revamp blends nostalgia with AI assistance, treating English as a high-level programming language; McCracken notes mixed feelings about AI-generated art and partial credit, and estimates the codebase at ~20,940 JS/CSS lines versus 141 BASIC lines.

Pragmatic Summit findings: 92.6% of developers use an AI coding assistant at least monthly, ~75% weekly; AI-authored code now ~26.9% of production code, with nearly a third of merged code written by AI. Onboarding time to the 10th PR has halved since 2024. Despite usage, productivity remains ~10% gains. Differences hinge on organizational readiness: well-structured teams gain a multiplier, while struggling orgs expose flaws. Real impact requires company-wide change, not just tools. Success hinges on clear goals, Developer Experience, and fast CI/docs/services; Codex is dominant.

The author recounts a journey from Pascal/C to Rust, building a money-making web app, then migrating to Node.js. While admiring Rust’s memory control, tooling, and safety, he cites long compile times, heavy CI, and web-ecosystem gaps—templating, i18n, and dynamic data handling. He moved to a Rust API + Astro frontend, but maintenance and iteration slowed. Node.js offers mature libraries (zod, kysely, i18n), better async, and easier templates and translations, cutting iteration cost. He concludes Rust excels at CPU-heavy tasks, but for his web app needs, farewell for now.

Don Marti argues that micropayments could restore direct revenue for news sites amid fragmented readership by turning untapped reader demand into incremental income, while supplementing subscriptions and advertising with verifiable, human-audience data. He proposes practical rollout ideas—subscribers receive coins or free gifts for non-subscribers, and coins help access—aimed at reducing friction and boosting UX. The piece also highlights declining advertiser ROI, the need for trustworthy attribution beyond Big Tech, and a careful, staged adoption to avoid user pushback.
