One low-end x86 machine, one Rust engine, and the idiomatic Biopython and Biostrings implementations measured on the same inputs with 10 timed repeats each — under a pre-registered decision rule with bootstrap confidence intervals: 7 of 8 capabilities show a material gap (1.4×–200× against the Python arm, 2.2×–1382× against the R arm); one is detectable but immaterial.

Linxira OS is built with AI tools — we encourage AI contributions and require honesty. External contributors must disclose every model and every agent tool actually used. We apply five-tier review depth based on model capability, with deliberate adjustments. Organization members with AGENTS.md trust chains are exempt.

Pre-launch validation for GPU vendor support in the Linxira Bio SDK, run entirely on established community benchmarks (the official Vina tutorial system, the STREAM convention, pytrf as the reference implementation) on one NVIDIA and one Moore Threads server: correctness, byte-level reproduction, and speed. The docking search budget gets a clear enough line (e=8 loses the pose 1 in 3; e>=32 never did), five classes of outputs hash-identical across vendors, and the Rust implementation holds a steady 3.6-4.0x over the traditional Python tool.

Linxira's base is upstream Arch, so can we go the other way — turn a machine that already runs Arch into Linxira with a single command? This post sorts out which layers are cheap, which one actually bites, and how we intend to do it (and what we explicitly will not).

linxira-update 0.1.3, Welcome 1.0.4 and installer fixes in the next image: ownership misdetection, COSMIC gray tiles, dark mode, CN mirrors and Flathub preseeding — plus the last layer of third-party distro dependency removed.

Linxira ships KDE Plasma and COSMIC as two first-class desktops, offline and checksum-verified: Windows background → KDE, macOS background → COSMIC — and COSMIC can be laid out as a classic top-bar + dock too.

DHH's Omarchy proves the pull of Arch plus AI workflows. Comparing its temporary-sudo agent model with our scoped user-group design, monthly rolling cadence, online-install auto-upgrade and the full-bootstrap roadmap.

Linxira Bio SDK benchmark: Rust/Python/R three-backend consistency, bit-level reproduction of an existing salmon pipeline on 10 samples (TPM r = 1.000000, NumReads diff 0), and a 26-sample backfill batch that auto-resumed 20 seconds after a real scheduled reboot. All data sources and environments disclosed.

Why Linxira moved from Linux Mint to Direct Arch — the desktop-supercomputer positioning, software ecosystem, and first-party toolchain.

ISO download, release highlights, install-test results, and what changed since the betas.

A standard systemd target switch that turns the desktop off and frees all RAM for compute.

How mandatory pacman signatures, release-key rotation, and a PKGBUILD CI gate block tampering.

The architecture behind one reviewed metadata source shared by the installer, Welcome, and graphical package management.

Dual-kernel fallback, automatic pre-update snapshots, and direct rollback from the GRUB menu.

npm mirror acceleration plus one-line installs of Claude Code, Codex, Gemini CLI, Grok, and OpenCode.

How the new beginner's guide covers terminal basics, Arch Wiki navigation, Chinese input troubleshooting, and desktop choice.

What is Linxira OS, who is it for, and why we built it. Design philosophy, technical architecture, and target users.
