tl;dr: Anthropic released Claude Sonnet 5, an agentic model that approaches Opus 4.8 performance at lower cost, with improved reasoning, tool use, and coding, plus longer autonomous task execution. Pricing starts at $2/M input and $10/M output tokens (introductory, through Aug 2026), rising to $3/$15 after; it's the default for Free/Pro plans and available via the Claude API. Safety evaluations show lower rates of misaligned behavior than Sonnet 4.6, and cyber safeguards are enabled by default despite the model being unable to develop full working exploits in testing. | |

| 227 points by reconnecting 12 hours ago | 42 comments | permalink | |
tl;dr: Copybara is a Google-internal tool, available on GitHub, for transforming and syncing code between repositories—commonly used to keep a confidential repo in sync with a public one, or to import external contributions back into an authoritative source. It's stateless (storing state as labels in destination commit messages), configured via Starlark-like files (copy.bara.sky), and currently supports Git with experimental Mercurial read support. Workflows define origin, destination, file globs, and transformations like path moves and string replacements. | |

tl;dr: Anthropic has released Claude Science, a macOS/Linux beta app that turns Claude into a research workbench for life sciences, with connectors to 60+ scientific databases, native viewers for proteins/structures/genomic data, and orchestration of compute on laptops, HPC clusters (via SSH/Slurm), or Modal. Every figure, table, and notebook is tied to the exact code, environment, and conversation that produced it, with a background reviewer flagging untraceable claims. It's available on Pro/Max/Team/Enterprise plans, with discounted access for academic labs. | |

tl;dr: Google released Nano Banana 2 Lite (Gemini 3.1 Flash-Lite Image), a faster, cheaper version of its Nano Banana 2 image generation/editing model aimed at high-volume and real-time use cases. It supports text-to-image, edits, and multi-image composition via a single API, with partners like Figma Weave, Manus, and Latitude citing ~2.7× speed gains over Gemini 3.1 Flash Image while approaching full Nano Banana 2 quality. Known limitations include fine details, text accuracy, complex masked edits, and occasional character consistency issues. | |

tl;dr: The LHC has shut down after its final physics run to begin Long Shutdown 3 (LS3), a major upgrade program running until 2030 to transform it into the High-Luminosity LHC (HiLumi LHC), which will boost luminosity up to tenfold. The work includes replacing 1.2 km of magnets, major overhauls of the ATLAS and CMS detectors (new trigger systems, silicon trackers, picosecond-timing detectors), and renovations across CERN's accelerator complex. Beam operations are expected to gradually resume in 2028, with HiLumi LHC physics starting in 2030. | |

tl;dr: KNOPPIX is a bootable Live Linux distribution that runs from CD, DVD, or USB without requiring hard disk installation, featuring automatic hardware detection and broad peripheral support. It functions as a desktop OS, rescue system, or software demo platform, with up to 2GB of compressed software on CD or 9GB on the DVD "Maxi" edition. | |

| 1165 points by stared 1 day ago | 725 comments | permalink | |
tl;dr: Qwen 3.6 27B is a locally-runnable dense model that reportedly matches mid-2025 frontier models (GPT-5/Claude Sonnet 4.5) on benchmarks, handling coding, writing, and general tasks well from a single prompt. On a MacBook M5 Max, it runs at ~32 tok/s via llama.cpp with multi-token prediction using ~42GB RAM (8-bit quantization), and fits on a 5090 at Q6 quantization. The author prefers it over the faster MoE 35B A3B variant for higher-quality output, and sees local models as increasingly viable alternatives to subsidized proprietary APIs. | |

tl;dr: The Supreme Court ruled 6-3 to uphold birthright citizenship under the 14th Amendment, rejecting the Trump administration's executive order that sought to deny citizenship to children born in the US to parents in the country illegally or temporarily. Chief Justice Roberts' majority opinion grounded the ruling in English common law and Reconstruction history, while Justice Thomas dissented, arguing the Citizenship Clause was narrowly intended for freed slaves. In response, the DOJ directed prosecutors to crack down on "birth tourism" schemes, and Trump called on Congress to legislate against birthright citizenship despite the constitutional ruling. | |

tl;dr: A developer has ported Linux (kernel 7.1.0-rc6) to the Sega Mega Drive, using a Mega EverDrive cartridge to provide 4MB of RAM via its SSF2 mapper, USB serial console access, and SD card storage. The system boots via U-Boot, runs on the 68000 CPU, and even offers a video console output on the Mega Drive itself, though performance is currently "insanely slow" and slower than a comparable 12MHz 68000 system. A QEMU fork is included for testing without real hardware. | |

tl;dr: The Human-Centered Computing Foundation is applying through ICANN's Applicant Support Program to create a new .self top-level domain dedicated to self-hosting and ethical, human-centered technology. The initiative aims to counter the data-extraction and attention-exploitation practices of the current tech industry by providing an alternative web architecture. Details on implementation are light, with the announcement primarily serving as a campaign launch pointing to a downloadable initiative overview. | |

tl;dr: Installing and logging into the Cursor iOS app silently migrated the user's account from "Privacy Mode (Legacy)" (no code storage) to the newer, weaker "Privacy Mode" that permits code storage for background agents. Cursor support confirmed the change is irreversible—the legacy option has been removed from all menus and cannot be restored. The user warns others to avoid the iOS app if they want to preserve stricter privacy settings. | |

tl;dr: MacOS 26 (Tahoe) forced all third-party app icons into a uniform "Liquid Glass" squircle shape, imprisoning non-conforming icons in an ugly gray background and reducing usability by making icons harder to distinguish at a glance. While MacOS 27 (Golden Gate) betas show Apple walking back some Liquid Glass excesses on their own icons, the author urges Apple to go further and restore the ability for app icons to have distinct, varied shapes. | |

| 20. | A native graphical shell for SSH(probablymarcus.com) |
| 362 points by mrcslws 1 day ago | 213 comments | permalink | |
tl;dr: Outer Shell is an open-source project that provides a browser-based graphical "shell" for SSH, letting servers serve up native GUI apps to remote clients. Each app runs as a small HTTP server communicating over Unix domain sockets (with SSH handling encryption), and apps can register capabilities so they interoperate—e.g., one app opening files in another. The author argues this fills a long-neglected gap alongside tools like Jupyter, and AI-assisted coding now makes truly native per-platform apps practical. | |
