Tangled argues that code hosting should combine the convenience of a modern forge with the durability and independence of open protocols. Built on AT Protocol and Git, it lets teams host some or all of the infrastructure themselves while continuing to collaborate across the network. Owners can customize the system, build extensions, or create alternative services and interfaces. The premise is that projects should not depend on one provider’s uptime or stewardship, and that open, adaptable infrastructure gives developers more control as software practices change.
The release introduces a redesigned Svelte interface and a Rust indexer, bobbin, deployed across more than 11 regions to improve global performance. A new Rust server, knot2, handles Git and SSH, and stores issues, pull requests, comments, reactions, labels, and membership data alongside repository code as versioned collaborative objects. These records sync through AT Protocol; attestations written to users’ personal data servers verify changes made on a knot. Tangled also adds organization accounts with their own identities, invites, and shared repository permissions, plus support for stacked pull requests and comparisons between revisions. Private repositories, a command-line tool, language SDKs, and agent skills are planned for subsequent launch stages.

GCC can lower dense switch statements into jump tables, subtracting a constant when case values share an offset. It generally favors jump tables when the value range has no more than about eight entries per case label. (xoranth.net)

Linux 7.4 improves FAT32 file preallocation by allocating multiple clusters at once instead of one at a time. Benchmarks show speedups of up to 265× for operations using FALLOC_FL_KEEP_SIZE. (phoronix.com)
Firezone introduced Sanstun, a userspace WireGuard implementation in Rust with a sans-IO design that separates protocol logic from networking, time, and randomness. It replaces Firezone’s heavily patched Boringtun fork with an API designed for parallel use, easier testing, and reduced internal buffering. (firezone.dev)
pgrust’s new Gravity query engine runs up to three times faster than ClickHouse on ClickBench while supporting PostgreSQL’s SQL dialect and types. Its JIT compiler was designed by measuring highly optimized Rust queries against the hardware’s performance limits and working backward. (pgrust.com)
The xarray-sql project demonstrates deriving a FlashAttention kernel from about 25 lines of SQL. Its benchmark implements attention operations and measures the generated kernel. (github.com)
