Byteification retrofits subword LLMs to operate on UTF-8 bytes with minimal extra training. The LTLM-based architecture pools bytes into patches via a boundary predictor with one-byte lookahead, processes patches with a deep global transformer, and depooled back to bytes through a local decoder. The two-stage training first distills the subword behavior while freezing the global model, then trains end-to-end to use byte-level information. The resulting Bolmo 7B, Bwen 8B, Blama 8B close or match state-of-the-art subword LLMs, outperform earlier byte-level models, and excel at character-level tasks, with efficiency benefits and easy ecosystem reuse via post-training.
Veda is an agentic-native operating system: an x86-64, Rust-based OS that embeds an AI agent as a first-class system service. The agent controls the desktop, windows, files, network and apps via agent-described actions, with consent for sensitive tasks and no screen scraping. It uses a capability-based microkernel (vkernel) and a Linux driver VM, with a GPU renderer and an agent-compatible desktop. Voice interactions rely on Deepgram; memory stays on the local machine. Built and tested with cargo xtask and QEMU.
Anthropic updated Claude’s usage policy to prohibit sustained, needless abuse of the chatbot, with enforcement via Claude ending conversations; the change takes effect November 12 and applies only in extreme cases. The broader overhaul tightens rules on deceptive influence campaigns, clarifies that weapons-development guidance is disallowed (and extends the weapons ban to software and components), bans surveillance and tracking without consent, and requires a qualified human operator to monitor any Claude-connected hardware. The update aims to address security risks while offering free security scans for eligible open-source projects and refining political targeting rules.
Over months, author used autonomous AI agents to decompile a popular FPS into readable, portable C++. They orchestrated Claude and Codex models, Discord, GitHub issues, and ida-mcp, achieving ~80% decompilation in month one. They reduced token use via earlier compaction thresholds. Semantics were often incorrect; lack of objective correctness allowed deviations. They built a byte-for-byte oracle comparing reconstructed code to the original, enabling automated PASS/FAIL checks and pushing only semantically identical results. In the end, about 99% of functions are present with 83% byte-exact; the game runs flawlessly. Key lessons: precise instructions, machine-checkable correctness, drift management, and scalable sandboxing.

diffle is a keyboard-first diff viewer with LSP support and GitHub integration. It provides a local server to review diffs with keyboard commands, uses language servers for code intelligence, and can send review comments to GitHub PRs. It supports various diff targets (HEAD vs worktree, PRs, commits), and requires GitHub tokens (GITHUB_TOKEN, GH_TOKEN) to post comments. Installable via npm, Nix, or standalone binaries on Linux/macOS/Windows; configurable with a diffle config. Current repo: moritzwilksch/diffle (Apache-2.0).
wallhop markets a free paywall bypass for articles, promising you can read any piece by pasting a link or using shortcuts. It provides iPhone Shortcuts, URL prefixes, a bookmarklet, and raw/API endpoints to access content, with guidance to bypass paywalls without signup. The project is a modified fork of open-source everywall/ladder (GPL-3.0) from wafflehacker.dev.
WerWolv recounts how he got several German Macromedia Director games to run on modern hardware by defeating their copy protections. He acquires disk images (CloneCD .ccd/.cue/.img), extracts the data despite decoy files, and installs via a separate Wine prefix. The key step is the embedded Director runtime in the .dxr, which ProjectorRays decompiles into a readable Lingo script. He patches the script to bypass the CD check and patches OPTGRAPH.DLL (the copy-protection DLL) to bypass disc verification. He wraps the changes in an auto-patcher. He notes many Director games use similar protections and can be made playable again.
Anthropic updated its 2026 Usage Policy to ban “sustained and needless abusive or cruel behavior” toward Claude, effective November 12, 2026. Enforcement uses the same conversation-ending tool introduced for Claude Opus 4/4.1 in August 2025, with a hard override to avoid harm to at-risk users. Normal frustration, dark fiction, or testing remain allowed. The update tightens rules on weapons software, surveillance, election targeting, and AI-controlled hardware, and requires qualified human review for high-stakes outputs with disclosure that AI was involved. No figures on how often endings occur.
Cockroach Labs built MOLT Sinai, a hospital-style, agentic coding pipeline to safely migrate databases. Roles like Triage Nurse, Fellow, Review Attending, and Discharge Nurse enforce planning, reviews, testing, and structured handoffs (I-PASS). In five months it processed over a million lines of code with just 7 reverts. Db2 migration support—the first major feature—took under two days with no human-written code, costing about $4,172 in tokens (164x faster, 38x cheaper than Oracle work). The pipeline produced extensive records and 1,570 commits (85% authored by the pipeline), but introduced bureaucracy; they’re refining for juniors and exploring partial/autonomous modes.

Explores "system one" decision models that emit calibrated probabilities by constraining outputs to a fixed set (A–E) and performing a single-pass prediction. Demonstrates constrained decoding with Qwen 3.1B to answer questions, showing initial predictions and a tendency to be overconfident. Evaluates on CommonsenseQA: baseline accuracy ~0.594, macro-F1 ~0.584. After lightweight finetuning, accuracy rises to ~0.624. Highlights calibration via temperature scaling to align confidence with accuracy, improving calibration across probability bins. A GitHub repo provides scripts to build datasets, evaluate, fine-tune, and calibrate models.
Researchers realize a solid-state nuclear clock by locking a 148.4 nm continuous-wave VUV laser to the 229Th nuclear transition in CaF2 crystals. They fabricated two crystals (S1, TS1) with thorium-229, resolved quadrupole-split QR and QU lines, and used a phototube-based absorption discriminator for fast, high-SNR readout. The clock achieved a fractional frequency instability of 5×10^-13/√τ, approaching photon-shot-noise limits, with line b reproducible between crystals and in agreement with JILA measurements. This demonstrates laser-addressed nuclei as operational clock references and a solid-state platform for compact nuclear clocks.

Damn Small Linux (DSL) started in 2003 as a 50MB Linux distro designed for old hardware. The 2024 version expands to about 700MB, built on Debian/antiX, and runs on aging machines (Pentium 4, first-gen Core, netbooks). It offers Fluxbox/JWM, lightweight browsers (Firefox ESR, NetSurf, Dillo), AbiWord/Gnumeric, and server tools, enabling web browsing, document editing, and file sharing. Installation via bootable USB, ~10 minutes; USB boot ~15s to desktop; hardware detection largely works. However, stability issues in live sessions, video playback problems due to drivers, and some apps fail. DSL revives old PCs, fits on a CD.
A Nature paper by ALPHA et al. reports a precise determination of the strong coupling αs at the Z mass, αs(MZ)=0.11876±0.00058 (4.9 per mille), using only low-energy QCD input. Through lattice QCD and a step-scaling (femto-universe) method, they compute αs across energy scales from hadronic inputs, simulating only up, down and strange quarks while adding charm and bottom effects perturbatively. Two independent approaches (varying quark masses and a quarkless limit) agree, aligning with the PDG average and strengthening the Standard Model test by predicting high-energy behavior from low-energy data.
