Splash is a three-digit color system in which each digit (0–9) encodes a red, green, and blue channel. Examples: 900 is full red; 000 black; 999 white. It helps avoid decision paralysis by limiting choices. There are 1000 possible colors, and designers can use standard sets or personal themes (e.g., pastel shifts). Conversion to hex can be done by simple math or with a hand-written lookup table. The method is fast, human- and machine-readable, and easily integrated into CSS/SCSS via functions or prebuilt styles.

Simon Willison introduces micropython-wasm, an alpha Python sandbox that runs Python in WebAssembly using MicroPython. It targets safe, plugin-like code within Datasette and Datasette Agent, with PyPI-installable dependencies, strict memory and CPU limits via wasmtime (fuel), and restricted file/network access plus exposed host functions. The prototype maintains a persistent interpreter across runs via a session and code-queue, with a small C bridge (78 lines) to connect host calls. It ships a CLI and Datasette integration. Caution: experimental and not yet recommended for production use.

Xlovecam's jiggle-physics is an open reference standard for real-time jiggle motion built from weight-painted regions and damped spring bones. The core rule is vertex += weight * boneJiggle. It’s engine- and renderer-agnostic: physics (jiggle-physics.js) separate from rendering (jiggle-app.js), with a WebGL demo and five test geometries. Weights are painted on a UV map; each region is driven by a damped spring bone with randomized stiffness/damping. The system outputs per-vertex bone offsets for use in any renderer.

The LWN piece analyzes fork() + exec() costs in Linux and Li Chen's spawn_template proposal to cache executable state and predefine actions for repeated launches. The patch would create a template via spawn_template_create, then spawn via spawn_template_spawn with argv, envp, pidfd, and an actions array to adjust fds, CWD, and signals; execution would still perform normal exec checks. Benchmarks show small gains (~2%). The consensus: kernel spawn templates will not be accepted; future work likely aims to implement a posix_spawn()-like path, possibly via a pidfd-based interface or user-space solution; io_uring discussions follow.

Explains building a Rust procedural macro to turn an annotated struct into a bitfield with generated accessors. The article covers proc-macros, TokenStream, syn and quote, and how to parse Rust syntax into an AST and emit code back. It defines data structures (BitFields, BitField, FlagAttribute, FlagPermission, FlagMeta) and uses attributes like #[bitfields] and #[flag(...)] to drive codegen. It derives backing types from bit widths (B8 -> u8, etc.), computes masks, and generates read/write/clear/build/Debug/From/ToTokens implementations. It also notes proc-macros run at compile time and crates must opt-in with proc-macro = true.

Rare book collecting is booming, especially among under-35s seeking tangible links to the past. Since WWII, ILAB and ABAA formed, and the trade shows activity: NYIABF drew 15,400 visitors from 174 exhibitors; 2022–2026 growth is 62%. The global rare book market exceeds $7 billion and grows over 6% annually. Rarity spans ancient manuscripts to 20th‑century ephemera and objects like Beckett’s inscription, a Zappa jacket, and a Magna Carta vellum edition. Collectors prize personal histories, annotations, provenance, and ‘time travel’ heft, often pairing books with art and archives. Start with what interests you; the field is diversifying and online-enabled.

X OS is a clean-slate x86_64 microkernel OS with a minimal kernel doing scheduling, memory, and IPC; all other services run in ring-3 userspace and communicate via IPC. Init and the display server are embedded in the kernel image. The design avoids POSIX; aims for an AI-friendly, modifiable system with live programming and bundled source. App bundles include the code; user customization is guarded to preserve visual coherence. Build requires macOS tools and QEMU; project uses a Business Source License 1.1 with commercial-use restrictions. Repository layout includes kernel, userspace, and boot components.

HISE is an open-source toolkit for building virtual instruments and audio effects. It provides modular audio blocks (sampler, synths, modulation, FX), an inbuilt IDE, a WYSIWYG interface designer, and a JavaScript-like scripting API with a DSP graph (ScriptNode). It can compile native plugins (VST/AU/AAX) for Windows, macOS, and Linux, and supports the RHAPSODY runtime. It offers extensive docs and a community. Licensing includes GPLv3 or commercial Indie/Pro plans, with JUCE licensing considerations; development began in 2014.

A comprehensive self‑study guide for Python developers to learn Rust, bridging from dynamic Python to statically-typed Rust with memory safety. Structured in four parts: Foundations (chapters 1–6), Core Concepts (7–12), Advanced Topics & Migration (13–16), and Capstone (17). Includes hands-on exercises, pacing times, and a CLI tutorial (temperature converter) and a capstone CLI task manager (rustdo). Covers installation, types, control flow, data structures, enums, ownership and borrowing, modules, error handling, traits, generics, closures, iterators, concurrency, unsafe, PyO3, testing, migration patterns, best practices, and resources. Encourages using Rust Playground and reading compiler errors.

Virgin Media’s 1Gbps Gig1 is affordable, but the author questions its value in 2026. Real-world use rarely needs more than about 100–500 Mbps, limited by Wi‑Fi physics, Ethernet gear, and CDN latency, not raw speed. Direct tests show wired speeds near 940 Mbps, Wi‑Fi around 450 Mbps, with speed tests capping around 700 Mbps. Uploads at 110 Mbps are usually ample. Possible self‑hosting, VPN access to geo‑blocked content, or 24/7 security-camera backups exist, but public exposure risks and costs dampen appeal. The government’s push for gigabit remains future‑looking; 500 Mbps might already suffice.

Google will pay SpaceX about $920 million per month from October 2026 through June 2029 to access roughly 110,000 NVIDIA GPUs, CPUs and related components. The deal, announced in a regulatory filing, is similar in scope to SpaceX’s late‑May pact with Anthropic and covers about half the compute Anthropic has at Colossus 1. Google may use Colossus 2 for xAI; both sides can cancel with 90 days’ notice after December 31, 2026. Ramp‑up through September will be at a reduced fee. SpaceX plans an IPO valued around $1.75 trillion.

Researchers reveal Bright Data’s SDK turns iOS devices and smart TVs into residential proxy exit nodes for AI training. Embedded in partner apps, brdsdk.framework fetches an unauthenticated sdk_config, then opens a WebSocket to proxyjs.brdtnet.com to relay scraping traffic from the device’s IP. The tunnel uses no auth, streams telemetry (battery, network, CPU), and executes scraping commands (tun, dns) when idle, bypassing VPNs via a required-interface path. Partners include PlayWorks, CloudTV, Longvision, Viber, etc.; per-country quotas exist (default 500 MB/mo; tighter in Uzbekistan, Oman, Qatar, UAE). Defenses: DNS blocks, TLS-SNI filtering, TLS fingerprinting, and MDM.

ComputeSDK’s 100,000-concurrent-sandboxes effort taught true concurrency is different from burst throughput. v1 ran 10k on one VM, exposing hardware bottlenecks. They adopted sharding across many VMs with shard metadata, landing on ~100 iterations per shard. The experiment now keeps sandboxes alive to measure peak concurrency, not just creation speed, and classifies outcomes as success, partial, readiness failed, or failed. Per-shard logs and a two-store data pipeline (Tigris for raw data, Clickhouse for analytics) ensure visibility and scalability. Final results are pushed to June 17.
