VMAF is Netflix's Emmy-winning perceptual video quality assessment algorithm using multi-method fusion. The Netflix/vmaf repo provides a stand-alone C library (libvmaf) and Python bindings, with tools to train/test custom VMAF models. It also includes metrics like PSNR, PSNR-HVS, SSIM, MS-SSIM and CIEDE2000. The project releases model sets (v1), libvmaf v3.0.0, and CAMBI with NEG mode. It is BSD+Patent licensed. Usage spans the vmaf CLI, FFmpeg filtering, Python wrappers, a Docker image, Windows build guidance, and contribution/docs.

Dominik Picheta created KillSwitch, an esoteric, human-friendly language designed to be hard for LLMs to read or execute. It includes hidden lies in the spec, letter-count rules, safety-trigger prompts, noise scripts, and line-count-based references; it’s a mostly ignored interpreter with a small set of constructs. He benchmarked LLMs and coding agents; Claude Opus tops the leaderboard, MiMo-V2.6-Pro open-weight performs best among open models, with a max score of 66.8. He argues this doesn’t prove real understanding; asks for tougher tasks and more capable models; code and spec are open source.

A long-form report on a Broadcom 802.11 vulnerability present since 2010 in Broadcom’s SDK, with an incomplete 2018 patch and a shift to hostapd. The flaw enables remote, unauthenticated code execution and information disclosure over WiFi, without a network key or standard WPS enrollment, affecting Broadcom-based devices on eCos and Linux. Dozens of vendors and millions of APs are affected; demonstrations show unpatched Belgian ISPs (Proximus, VOO, Orange) with root access and PSK exfiltration from NVRAM. Broadcom knew of the issue since 2018 but refused to assign a CVE; patches were not deployed by Oct 15, 2026.

Researchers led by Eleonora Biffi tested 70 domestic dogs to see if they link 'Bouba' with round and 'Kiki' with spiky shapes, as humans do. In the first setup with owners present, dogs tended to look at the rounded shape when 'Bouba' was spoken and at the spiky shape when 'Kiki' was spoken. In the second setup, with owners wearing headphones to remove cues, the bias disappeared, suggesting possible owner influence. More research is needed. Published in Proc. R. Soc. B.

Developing for Debugging explains Oxide's DNS architecture: external vs internal DNS, both derived from CockroachDB data, with Nexus updating config and background tasks propagating to DNS servers. To diagnose issues, the Omicron debugger (omdb) exposes a live view of DNS_config_internal, dns_servers_internal, dns_propagation_internal, including last activations, servers, and results. This debugger-driven approach makes propagation failures traceable, provides affirmative evidence of success, and supports testing, demos, onboarding, and reducing support stress.

Geographical Fun is a Hodder and Stoughton 1868 series of humorous anthropomorphic maps of Europe, each with a witty quatrain. While the Library of Congress credits the intro and lines to "Aleph" (William Harvey), the piece doubts this and suggests a teenage girl may have drawn the plates. The twelve plates caricature England as Queen Victoria; Scotland as a piper; Wales as Owen Glendowr; Ireland as a peasant; France as an Empress; Italy as a revolutionary; Prussia with Wilhelm and Bismarck; Holland and Belgium as female figures; Denmark as an an ice-skater; Russia as a bear. The text notes educational aims and public-domain availability.

Anthropic announced the Anthropic Public Benefit Fund, a wholly owned LLC that will hold rising shares to finance the public good. Starting today, 5% of Anthropic’s shares are committed to the Fund, with an additional 2% for every 50% rise in value above baseline, at board discretion. The Fund can support large nonprofit gifts or targeted distributions, including labor-market initiatives; Anthropic has already pledged $200M to study this. About 20% of shares will be dedicated to the public good, with more as milestones are reached. Governance details and progress will be shared later.

First full dynamic package support for the Free Pascal Compiler and Lazarus IDE is released. Dynamic packages are shared libraries (Linux/Windows/macOS) with metadata, enabling plugins and modular components without rebuilding the IDE; runtime RTL supports loading, enumerating, searching, and unloading packages and cross-package dynamic types. Restrictions: package unit names cannot match the package; unit names must be unique across packages; stripping metadata breaks functionality. New DynPkgTypes.pas and TPackageType definitions. Lazarus adds a progress window for package rebuilds, a Packages window, faster package updates, platform/widgetset restrictions, and a form/frame converter. Available now; GitLab branches; forums for discussion.

Florida HOAs and condo associations are worsening the housing crisis by aggressively using liens and foreclosures, pushing up dues and assessments, and mandating repairs after Surfside. HOA Spy tracks 104,659 associations, with 10,296 foreclosure suits against members, 460,412 liens, 277,047 lis pendens, and 48,999 association-named court records. Many associations are lapsed or not in good standing. The 2022 SB 4-D rules require milestone inspections and funded reserves, raising owners’ costs and affecting prices. Buyers should scrutinize association records, budgets, reserve studies, and inspection reports before buying.

CKKS — Addition and Multiplication explains how addition and multiplication work on CKKS ciphertexts (without relinearization). Ciphertexts are pairs (c0, c1) in Z/QZ[x]/(x^N+1); addition is componentwise with noise growing sub-Gaussian. Multiplication expands to a degree-2 form (t0, t1, t2) that decrypts as c0d0 + (c0d1 + c1d0)s + c1d1s^2, causing quadratic noise growth and a Delta^2 scale. To continue arithmetic, one uses rescaling (restore scale) and relinearization (reduce back to two components). The post includes Deg2Ciphertext code and decrypt_deg2 tests.

Mitos is a modal, batteries-included text editor centered on selections and multi-cursor editing. It ships with built-in language tooling: LSP support (completion, diagnostics, go-to-definition, rename, formatting, code actions) via configured language servers; Tree-sitter for syntax highlighting and syntax-aware navigation; and a Debug Adapter Protocol (DAP) for breakpoints, stepping, and variable inspection. It also offers terminal image previews, and file navigation/search (explorer, picker). It is open source under MPL-2.0.

In July, Eddie Abbondanzio converted his Razor A5 Lux push scooter into an electric one using a front-wheel-drive Hercules 20V drill. A keyed shaft and one-way bearings transmit power to the front wheel, with the trigger relocated to the handlebars for throttle. The setup tops out around 10 mph, is slower uphill, and runs on a 5Ah battery for about 2 miles. The front wheel is a 3D-printed ASA wheel with a TPU tire; wiring was messy. It was a fun, improvised project that didn’t save money compared to buying an electric scooter.
