Visual Basic on the PC with Windows 3.1

An examination of Visual Basic on Windows 3.1 and its place beside Apple HyperCard as a pioneering visual programming tool. Tracing Gates’ push to own the PC stack, the piece covers VB’s origins (via Tripod/Ruby) and its 1991 debut, its drag‑and‑drop UI, data binding, and the ability to call DLLs, contrasted with HyperCard’s scripting. It critiques VB3’s bloated UI, opaque property systems, and heavy manuals, while praising its editor, grid snapping, and ‘edit and continue.’ It notes 16‑bit limits, 2008 discontinuation, ongoing legacy via emulation, and ends with questions about lasting impact of modern tools.

Meta Caps Internal AI Token Spending After Costs Approach Billions in 2026

Meta is tightening internal AI spending after token usage neared billions in 2026. A memo to about 6,000 staff said 73.7 trillion tokens were used in ~30 days, tracked on a Claudeonomics leaderboard. CTO Andrew Bosworth warned that token volume alone isn’t a measure of impact and pushed back on 'tokenmaxxing.' Meta will replace the leaderboard with an AI Gateway dashboard and implement formal token budgets in 2027, while steering staff toward MetaCode and away from Claude. The company also plans up to $135B in AI infra spending through 2026 and $600B in data-center buildouts through 2028.

The <Usermedia> HTML Element

Chrome introduces the <usermedia> HTML element (Chrome 151) as the next Capability Element after <geolocation>, to manage camera and microphone access declaratively via a browser-controlled element, reducing boilerplate and improving security and recovery after denial. It handles prompt, delivers MediaStream, supports setConstraints(), events stream, error, cancel, and enforces styling constraints for user trust. Provides fallback to legacy getUserMedia if unsupported. Migration from Origin Trial; roadmap includes <camera> and <microphone> elements. Validation from Origin Trial shows higher permission grant success and fewer errors.

Opening up 'Zero-Knowledge Proof' technology to promote privacy in age assurance

Google Wallet has open-sourced its Zero-Knowledge Proof libraries to advance privacy in age verification, in partnership with Sparkasse for EU age assurance. ZKPs let users prove statements (eg, being over 18) without revealing other data. The open-source codebase at github.com/google/longfellow-zk enables developers, businesses, and researchers to build privacy-preserving apps and digital IDs. The move aligns with EU eIDAS (2026) encouraging ZKP for the European Digital Identity Wallet (EUDI Wallet).

Client-side load balancing at a million requests per second

Zalando built an in-process client-side load balancer (CSLB) to replace internal fan-out via the cluster’s shared edge, handling over 1M rps with features: N-ring fade-in, occupancy-based bounded load, and AZ-aware routing with a latency health factor. They matched Skipper’s hash ring (xxHash64) to avoid cache churn, used Kubernetes informers, and vastly sped up deployments. Rollout cut Skipper traffic from ~1M rps to CSLB, reduced Skipper pods from 50+ to 8, and saved >$1k/day. They implemented Little’s-law occupancy signal, a 150ms sliding window, a capped walk, a FIFO for bursts, and hardened retries. Zone-aware routing remains paused; build-your-own advice stands.

Why jet engines aren't made in China

Jet engines reveal the limits of China’s state‑capitalist catch‑up. Despite enormous investment, China remains a decade behind the West because engines require slow iteration, extreme reliability, and a vast tacit, globally linked supplier network. The CJ‑1000A and C919 rely on Western components, and FAA/EASA certification is unlikely soon; margins are razor‑thin, limiting new entrants. Military engines show some progress but lag Western standards (WS‑15 vs F‑119). By contrast, China excels in mature, high‑volume sectors (EVs) via vertical giants, while the West benefits from private capital and faster, asymmetric innovation.

The Underhanded C Contest

Results of the 2015 Underhanded C Contest, run with the Nuclear Threat Initiative. With 40+ submissions, it features many runners-up and a final winner. The challenge centered on a nuclear-verification problem using spectra data and an information barrier. Submissions describe NaN poisoning, data- and environment-triggered attacks, and realistic exploitation. The winner, Linus Åkesson, presents a clever type-confusion bug (interpreting 8-byte doubles as 4-byte values via float_t) that distorts data yet passes energy tests. The post also notes contest timing and prize details.

Healthy but Sedentary People Show Early Decline in Cellular Energy Production

CU Anschutz researchers found that healthy but sedentary adults show early, coordinated declines in muscle mitochondrial function, reducing the ability to burn sugar and fat. In nine sedentary vs ten active men (~42), sedentary individuals had 28–36% lower mitochondrial efficiency, 49% less MPC1 protein, about half CPT1 activity, 38% lower VO2 max, and 60% higher lactate during exertion. These cellular changes may precede diseases like insulin resistance, type 2 diabetes, cancer, and Alzheimer's. Exercise is highlighted as a cellular shield, with plans for larger studies and non-invasive early-detection tests.

Chip Off the Old Block

Scott Alexander meditates on how having kids reframes poetry and youth. A son’s train obsession echoes his own quirky childhood; a daughter’s art hints at a prodigious lineage. Children inherit tastes and the habit of narrating thoughts, generating memes and future writers. The piece pivots to parenting as a feudal bargaining system: bedtime becomes a negotiated equilibrium of two minutes, songs, and brushing teeth, with “Danegeld” payments and the risk of escalating demands. Online critics, genetics, and culture collide as he weighs peace at night against autonomy, concluding the routine shapes rather than limits their futures.

The Apple Disk II Controller Card

The Amazing Disk II Controller Card explains why Apple II disks used Disk II vs other controllers. The Disk II is a minimal, hardware-light controller that offloads complexity to software, enabling cheap floppy support. It covers basic floppy concepts (300 RPM, tracks, arm movement), and four software-driven challenges: framing bytes, encoding (GCR 6-and-2 vs 5-and-3), sectoring (D5 AA 96 signature marks sector starts), and track finding. The bootstrap routine fits in 256 bytes, loading sector 0 via a tiny ROM and a state machine. The article contrasts Disk II with modern controllers and points to BMOW's Floppy Emu and Yellowstone project.
