Linux 7.3’s merge window is still open, but what’s already confirmed looks like the foundation for one of the more performance-heavy releases in a while<\/a>. Btrfs direct I\/O is pushing close to 95% of theoretical throughput, EXT4 is hitting 2.19 million IOPS on fast NVMe, and a KSM memory bug that caused 700ms freezes is fixed down to under 2ms.<\/p>\n

Canonical is co-funding a three-year PhD<\/a> at the University of Bristol to build a system that can translate large C codebases into Rust automatically. The test cases are AppArmor and snap-confine, both already running in production on Ubuntu, picked specifically because they’re complex.<\/p>\n

While not FOSS, TeamSpeak has been consistent in supporting Linux as a platform. It is now getting the ability to make direct calls<\/a> between users without requiring a server.<\/p>\n

Proton Mail’s new Categories feature<\/a> is live and works similar to how Gmail tabs do, sorting incoming mail into Primary<\/em>, Social<\/em>, Promotions<\/em>, Newsletters<\/em>, and two optional categories. The difference is that Proton sorts by metadata only since it can’t read your email contents.<\/p>\n

A one-line kernel bug in the Intel Xe driver was causing GDM to restart endlessly on Battlemage G21 cards. Tracking it down took Linus Torvalds 18 kernel boots and 24 debug patches<\/a>.<\/p>\n

There seems to be an official Flatpak package in early development for the Chromium browser<\/a>. <\/p>\n

Star Labs computers are designed for Linux<\/span><\/a> from the ground up, so things just work – without hunting for drivers or relying on vendor-specific software. With open-source coreboot firmware and more control over the hardware you own, Linux gets the preferred treatment over Windows here.<\/span><\/p>\n

\ud83e\udde0 What We\u2019re Thinking About<\/h2>\n

You might have already heard about Omarchy’s recent cash infusion<\/a>; here’s a quick run-down:<\/p>\n

Ten tech founders have each written a million-dollar check for the Omacom Foundation, a nonprofit that DHH is in the middle of setting up to fund Omarchy and the open-source ecosystem around it.m<\/p>\n

The first beneficiary is Vaxry from Hyprland<\/a>, who will receive funding under an exclusive 3-year sponsorship.<\/p>\n

The entire episode has (once again) divided the Linux community, as some people dislike DHH for his (right-leaning) political views, while the supporters don’t agree with the usual (left-leaning) political views of most Linux-related organizations. Guess politics spoils a lot of things.<\/p>\n
