Folding Beijing follows Lao Dao, a 48-year-old Third Space waste sorter, as Beijing folds into three spaces with 24-hour cycles for each population. Desperate to fund Tangtang’s kindergarten, Lao Dao undertakes an illegal mission to deliver a message to Yi Yan in First Space, traversing Second Space and the Change between spaces. Across these realms he witnesses stark class divides, temptations of wealth, and the looming threat of automation replacing workers. After a dangerous ordeal, he returns to Third Space injured and morally strained, yet determined to care for Tangtang.

PrismML introduces Bonsai Image 4B, two compact diffusion-model variants for on-device image generation: 1-bit Bonsai Image 4B with binary weights (0.93 GB transformer; 8.3x smaller) and ternary Bonsai Image 4B with -1/0/+1 weights (1.21 GB; 6.4x smaller). Both preserve most quality (88% for 1-bit, 95% for ternary vs FLUX.2 Klein 4B) and include FP16 projection layers, text encoder, and FP16 VAE. Deploys on Apple Silicon and CUDA; runs on iPhone 17 Pro Max where full-precision can't. 512x512 images in 9.4s (iPhone) or 6s (Mac); open weights under Apache 2.0; Bonsai Studio app.

David recounts building numerous AI-driven projects—many abandoned or unmaintained—and argues most aren’t useful. He contends AI tools amplify attention fragmentation, encouraging multi-tasking and shallow output. His experiments show automation can erode focus and writing quality. Drawing on Cal Newport’s digital productivity paradox, he suggests tools prompt busywork rather than deep work. To manage AI responsibly, he advocates curtailing use and prioritizing real outcomes and meaningful focus.

The piece argues that large organizations with tree structures constrain freedom and stifle initiative, especially for programmers. Humans are best in small groups (roughly 8) and doing things themselves; big companies create 'fake tribes' with limited agency as you go up the ladder, slowing innovation. Starting or joining a small startup provides more learning, more freedom, and a healthier mental state, even if stressful. Therefore, valuable advice: aim to keep companies small, hire well, and for programmers, do a startup rather than stay in a big firm; experience there improves growth and confidence.

Inkstravaganza highlights recent work in Ink & Switch's Programmable Ink: PlayBook, a dynamic, paper-like notebook built from composable components for sketching, writing, and collaboration. The piece previews ongoing directions: Portemine, exploring propagator networks as a visual, time-based substrate for SAT and constraint solving; Gestures, a touch-free input system with a 'firm press' tool switch and a custom event-dispatch model; DrawDeck, a mysterious rune-stone metaphor for spatial computation and memory, with demos. The note also mentions Local-First Conf 2026 Lab Day and invites readers to stay tuned and subscribe.

Vox investigates AI successionists—scientists, entrepreneurs, and thinkers who argue AI should replace or surpass humanity—and traces their growing influence. Sigal Samuel shows their beliefs rest on teleological views of the universe and a quest to “wake up” consciousness through technology, a lineage from Pico della Mirandola to transhumanists like Kurzweil. The piece argues this is a misguided, potentially dangerous religion repackaged as science. It calls for a 21st‑century humanism that rejects universal destiny, embraces diverse intelligences, guards rights, and pursues incremental, democratically guided tech progress that empowers humans.

Author buys a Tesla V100 SXM2 16GB datacenter GPU and, with a non‑NVIDIA SXM2→PCIe adapter (~£50), pairs it with a RTX 4080 for 32GB total VRAM to run a 27B Qwen model locally at ~32 tokens/s (128k context) via tensor splitting. All in ~£200. The V100’s 900 GB/s bandwidth beats many consumer GPUs. The big catch: an insanely loud fan (82 dB) fixed by PWM control with a JST adapter. Runs on NixOS with CUDA 12.2, vision support, NAS storage; occasional cold reboot ACPI quirk. Strong value in secondhand server GPUs.

United Airlines Flight 236, a Boeing 767-400ER from Newark to Palma de Mallorca, turned back to Newark after a passenger’s Bluetooth speaker name—reported as 'BOMB'—triggered a bomb-threat security alert. The plane squawked 7700 about an hour into the flight and landed back at 8:50 p.m. Local. Passengers later boarded a replacement flight around 2:30 a.m. after a security sweep; two Bluetooth devices remained active at the time. The incident comes amid recent similar threat scares involving hotspot names.

- Tidio: cheap, web-first for small e‑commerce; good if budget < $2k/mo; limited flow branching.
- Intercom: enterprise/B2B with sales focus; strong but expensive; onboarding can be lengthy.
- Wexio: multi‑channel inbox (WhatsApp, Telegram, IG, Viber) plus a web widget; flexible AI (BYO or built‑in) and lower AI costs; widget ships June 2026.
- Quick framework: WhatsApp/Telegram/Viber heavy users → Wexio; web-first, budget < $2k/mo → Tidio; 50+ employees with sales workflows → Intercom.
- Main note: AI cost gap drives most of the price differences; migration paths exist between them.

Two bad ways to use coding agents: unattended (bugs, PR floods) or micromanaged (human reviews every step). A third way introduces automated backpressure: guardrails that let agents work longer while catching errors early. In software, backpressure already exists via tests, types, CI, linting, canaries; these push responsibility upstream, letting humans focus on design. The post outlines building such a loop for LLM code: linting, tests, canaries, benchmarks, review agents, planning phase, visual reviews, PR monitoring, and a composable skill to run it. The goal: safe delegation and higher-quality AI-assisted development.

Dav2d is a fast, portable, correct software decoder for the AV2 codec, announced by VideoLAN and built on dav1d. AV2 is the royalty-free successor to AV1; its spec is public and typically yields ~25% better compression but ~five times more decoding work. Development began early so software can decode AV2 in real time before hardware support is widespread. The dav2d tree implements a feature-complete AVM v15 decoder (8/10-bit) and targets correctness, conformance, and architecture-aware optimization across x86 (AVX2), ARM (NEON), and RISC-V, aided by checkasm. It remains open source; further work will optimize performance and platforms.

Security Envelope Pattern collection (S.E.C.R.E.T.) catalogs and classifies security envelope patterns used to obscure printed information. The Society for the Exploration of Confidential Repetitive Envelope Tints invites Obscurationists—those who study and document these patterns—to browse, learn a classification system (order, family, genus, species), contribute patterns, and celebrate the mystery and beauty of tints used since 1901. Origins are largely unknown, and the project aims to standardize terminology and foster a community.

Mysteries of the Griffin iMate describes reviving a vintage Apple Extended Keyboard II via a Griffin iMate ADB-to-USB adapter. The iMate failed intermittently; the culprit is an undocumented CR1225 coin-cell battery in the iMate powering a “USB power button” circuit that ties ADB PSW to USB wake. Replacing a dead battery with CR1220 and adding a decoupling capacitor between BATT+ and ground restored reliable operation. The author traces the circuit, discusses noise issues, speculates on obsolescence, and concludes with lessons about not starting new projects.
