3 rules to it:

• the fastest code is the code you don't run.
• the smaller the code, the less there is to go wrong.
• the less you run, the smaller the attack surface.

Rewrite to native is also an option: Atom got 10x faster with Zed.
COSMIC desktop looks like GNOME, works like GNOME SHell, but it's faster and smaller and more customisable because it's native Rust code.

The COSMIC desktop looks like GNOME, works like GNOME Shell, but it's smaller and faster and more customisable because it's native Rust code. GNOME Shell is Javascript running on an embedded copy of Mozilla's Javascript runtime.

Just like dotcoms wanted to dis-intermediate business, remove middlemen and distributors for faster sales, we could use disintermediation in our software. Fewer runtimes, better smarter compiled languages so we can trap more errors and have faster and safer compiled native code.

Dennis Ritchie and Ken Thompson knew this. That's why Research Unix evolved into Plan 9, which puts way more stuff through the filesystem to remove whole types of API. Everything's in a container all the time, the filesystem abstracts the network and the GUI and more. Under 10% of the syscalls of Linux, the kernel is 5MB of source, and yet it has much of Kubernetes in there. This is what we should be doing. This is what we need to do. Hack away at the code complexity. Don't add functionality, remove it. Simplify it. Enforce standards by putting them in the kernel and removing dozens of overlapping implementations. Make codebases that are smaller and readable by humans.

Gnome Shell is
