Cerelog’s ESP-EEG is an open-source 8-channel biosensing board (EEG/EMG/ECG) powered by TI ADS1299, marketed for cleaner signal with true closed-loop active bias and priced near OpenBCI’s initial offering (less than half the Cyton’s current price). Software support includes a fork of the OpenBCI GUI via Lab Streaming Layer and BrainFlow. Created by ex-SpaceX hardware engineer Simon Hakimian. Licensing: firmware/software MIT; hardware schematics CC-BY-NC-SA (non-commercial). Caveats: USB only for now (no electrical isolation); Bluetooth/WiFi hardware present but firmware not ready; ESP32 platform with onboard LiPo charging and future WiFi streaming.

Spectre is a low-level, safe systems language with type-level invariants, function pre/postconditions, and default immutability. Contracts are checked at compile time when possible; otherwise runtime checks run under guarded constructs. Memory is manually managed via allocators. It compiles to QBE IR (experimental LLVM/C99 backends) and supports -translate-c to port C code. A Hello, world uses trust for impure IO; safe wrappers avoid trusting. Foreword notes the docs may be out of date.

Shifts from ephedrine-based to P2P meth (2009–2012) boosted supply and changed chemistry. P2P synthesis can yield both d- and l-meth, but modern meth is ~95% d-meth; by 2019 l-meth largely disappeared. Impurities arise mainly from the P2P step; lead acetate contamination does not explain schizophrenia. Two main routes: NTS from nitrostyrene and PAA/EtPA to P2P. The bigger story is greater availability, lower prices, and a rise in heavy meth use and overdoses.

Erlang/OTP 29.0 is a major release with new features and some incompatibilities. Highlights: -unsafe attributes add compiler warnings and xref support for unsafe/undocumented calls; SSH defaults to secure by default (shell/exec disabled; SFTP off). SSL uses mlkem768x25519-sha256 as the default key exchange. io_ansi enables ANSI terminal sequences; ct_doctest tests docs; ignore_xref is handled by xref. Default code path now places the current directory last; no 32‑bit Windows build. New features: native records (experimental), is_integer/3 guard, multi-valued comprehensions with compr_assign. Compiler/JIT improvements and several new default warnings. STDLIB adds rand:shuffle/1 and rand:shuffle_s/2. SSH KEX has fallback for compatibility.

EventQL is a SQL-inspired query language designed for event sourcing. It treats event metadata (type, subject, id, time) and payload (data.*) as first-class, enabling index-friendly, subject-scoped queries over event streams. With SQL-like constructs (WHERE, ORDER BY, GROUP BY, TOP/SKIP) and explicit projection via PROJECT INTO, it makes it easy to filter, sort, and reshape results across aggregates. The design emphasizes indexes on type, time, subject, and payload, and a production-ready Rust parser (AST with errors, tests) is available. A type-inference feature is planned. See eventql-parser on GitHub.

Naturally occurring quasicrystals are extremely rare. The first three were found in the Khatyrka meteorite: Icosahedrite (Al63Cu24Fe13) with full icosahedral symmetry; Decagonite (Al71Ni24Fe5), a decagonal two-dimensional pattern with periodic stacking in the third direction; and i-Phase II (Al62Cu31Fe7), also icosahedral but copper-rich. A possible natural example also arose in a Nebraska fulgurite from lightning, Mn72.3Si15.6Cr9.7Al1.8Ni0.6, with 12-fold symmetry; another known quasicrystal, Si61Cu30Ca2Fe2, was found at the first atomic bomb test. These phenomena are analyzed via higher-dimensional 'slice and project' constructions.

BBC tells how the Pintupi Nine, the last nomadic Pintupi family in the Gibson Desert, entered modern Australia in 1984 after decades of isolation following 1950s relocations for Blue Streak tests. Found near Kiwirrkurra by relatives and a help party, they faced cars, planes and sugar for the first time during a three-day bush chase. They joined settled life; some married quickly, one brother later returned to the bush. Now the siblings are acclaimed artists; their country is protected as the Kiwirrkurra Indigenous Protected Area, one of the world’s largest arid lands.

Jason Scott narrates the completion of the Manuals Plus project: 13,000 manuals digitized and online at Internet Archive after years of salvage, sorting, and fundraising largely by volunteers and the Digital Library of Amateur Radio Communications (DLARC). Some manuals remain undigitized due to corporate rights (HP/Agilent, Tektronix). He invites community reviews to improve metadata and notes funding needs. The piece also covers his office move and ongoing archiving work, plus reflections on the Living Computer Museum’s decline, billionaire philanthropy, AI hype, and his online-life stance, including blocking and VCF experiences.

London police will use live facial recognition at a protest—the first UK deployment—via lamppost cameras and drones in Camden for the Unite the Kingdom rally. The Met cites security concerns. The move follows a Croydon six-month pilot that scanned 470,000 faces and led to 173 arrests, though critics say 99.96% were not involved in crime and there is no parliamentary oversight. The system risks turning protests into surveillance zones and shaping who attends political events.

The article discusses migrating from the uMatrix extension to Chrome’s MV3 architecture. Since MV3 disallows blocking callbacks, requests must be intercepted declaratively. The author proposes using Content-Security-Policy with declarativeNetRequest and a reporting mechanism (report-to) to capture subresource requests and build allow/deny lists. A proof-of-concept called matrix³ is presented, with minimal code and instructions to load it as an unpacked Chrome extension. The goal is a CSP-based interface to manage site permissions similar to uMatrix; feedback and collaboration are invited.

Palantir has hired 32 senior UK government and public-sector officials since 2012, including from the MoD, NHS, Home Office, Foreign Office, UK Health Security Agency, Crown Commercial Service, secret services and Downing Street; four Lords, two generals and a former PM adviser are among the list. The report comes amid scrutiny of Palantir’s growing UK contracts (NHS, MoD, FCA and 11 police forces) and concerns about a revolving-door risk, with critics warning about privileged insights being used commercially. Palantir says 14 of the 32 no longer work for or with the company and rejects the revolving-door claim.

California's Protect Our Games Act advanced from the Assembly appropriations committee 11–2. It would require publishers who cut online game support to offer full refunds or an updated version enabling continued play independent of services, and to notify players 60 days before service cessation. The bill excludes free-to-play and subscription-only games; other games sold in California after Jan 1, 2027 would be subject if passed. SKG supports; the ESA opposes, citing licensing and feasibility concerns. The measure still needs floor votes in the Assembly and Senate and the governor's signature.

Meta’s Hyperion data center in Richland Parish, La., a $10 billion project, will receive about $3.3 billion in state and local tax breaks—enough to fund the police budget for more than seven years. Data-center subsidies are spreading nationwide, with Virginia at about $1.9 billion annually, Georgia about $2.6 billion, and Texas over $1 billion. Critics call the subsidies wasteful as projects multiply and opponents grow; lawmakers in many states consider guardrails or repeal. Meta says Hyperion will create more than 5,000 construction jobs and 500+ permanent roles, plus investments in local infrastructure and schools.

Zulip announces the creation of the Zulip Foundation, donating Kandra Labs to an independent nonprofit to ensure sustainability, independence, and a public-interest focus. The foundation will govern Zulip, while Kandra Labs is owned by the foundation and continues to host and improve Zulip. The initial board includes Tim Abbott, Greg Price, Alya Abbott, and Josh Triplett; interim President Kim Vandiver will oversee the transition. Zulip Cloud, self-hosted support, GSoC, and sponsorships stay unchanged. Tim Abbott and three other leaders will join Anthropic; the move broadens fundraising avenues via grants and tax-deductible donations. A live Q&A is planned May 19.

WinCE64 is a hobby reverse‑engineering project that runs Windows CE 2.11 on a real Nintendo 64 via a custom HAL/OAL and drivers, launching the nk.lib kernel with a CE 2.11 GWES desktop and shell. It mounts an EverDrive-64 X7 SD card as \SDCard, uses the N64 controller as a mouse, and can run third‑party CE 2.11 EXEs from the SD card (e.g., BeziersCE). The ROM isn’t provided; build it yourself with bsp/build.sh after supplying the CE 2.11 SDK (wince211_sdk) and libdragon alongside the repo. MIT‑licensed for source; binary SDKs are proprietary. Emulator support is limited.
