Your Linux apps could be leaking data -- oniux is built to stop it
A new tool called oniux has landed for Linux users who take their privacy very seriously. If you want to make sure your apps never leak data outside of the Tor network, oniux could be your new favorite command-line utility.
Oniux takes any Linux app and drops it into its own isolated network environment. From there, the app can only connect to the internet using Tor. This isn’t a trick with proxy settings or patched libraries. It uses actual features built into the Linux kernel, giving it a level of protection that’s hard to beat.
Ubuntu Linux swapping classic sudo for Rust-powered sudo-rs
Canonical is making a huge change in Ubuntu that longtime Linux users might not expect (or like). You see, beginning with the upcoming Ubuntu 25.10, the popular Linux distribution will begin the process of ditching the classic sudo tool in favor of a modern reimagining called sudo-rs. This change is more than a simple code swap -- it’s a sea change in how privilege escalation is handled on Linux, with a clear focus on security and long-term sustainability.
So what exactly is sudo-rs? Well, as the name implies, it’s a new implementation of the familiar sudo command, but this version is written entirely in Rust -- a programming language known for its strict memory safety and reliability. If you’re worried about compatibility, don’t panic; sudo-rs is designed as a drop-in replacement for the original. For most users, it will just work.
