10 of 11 AI coding agents fell to the same shell trick
Adversa AI disclosed GuardFall on 30 June 2026. Their bypasses got past the command filter in 10 of 11 open-source coding and computer-use agents. One held, Continue, and it held because it parses the command before judging it, rather than matching patterns in raw text. The trick is decades old. The guard inspects the string the model produced, and bash rewrites that string before running it. A regex reads r''m and finds nothing to match, then bash strips the quotes and runs rm. $IFS expansi...

IOmap Improvement For Linux 7.3 Takes EXT4 & XFS Performance Further
As part of the VFS pull requests now merged to the Linux 7.3 development kernel was an improvement to the IOmap framework used by various file-systems for mapping logical file byte offsets in memory to their physical locations on storage. With the now-merged code, this modern block mapping framework is allowing better performance at least for the EXT4 file-system...
Linux 7.3 Adds New "bpf_sock_read_xattr" Feature For systemd, BPF Programs
Merged earlier this year for Linux 7.1 was extended attributes on sockets support as a feature sought after by the likes of GNOME and systemd for helping with Varlink IPC usage and other purposes. A limitation though of the functionality has been no efficient means for a BPF program to read those user extended attribute labels back. But with Linux 7.3 that's being addressed with the new bpf_sock_read_xattr() kernel function...
New AMD Low-Power Core & Unified Intel/AMD CPU Core Type Handling In Linux 7.3
Covered first on Phoronix back in June was an AMD Linux patch for introducing a new "low power" CPU core type to complement their typical "performance" cores and their "efficiency" cores like with Zen 4C/5C. That low power core is presumed for some Zen 6 clients and that integration is now merged for Linux 7.3 as well as unifying the Intel/AMD CPU core type handling...

I Built My Own Smart TV With Linux
How I turned a regular Linux machine into a fast, beautiful TV experience without buying a Fire TV Stick or an Android TV box. Samay Kumar August 19, 2026 For the longest time, I thought the only way to make a TV "smart" was to buy something. A Fire TV Stick, an Android TV box, maybe an Apple TV if you're feeling fancy. And honestly, I didn't really want any of them. I already had a Linux machine connected to my TV, so buying another device just to get a better interface felt a little ridi...
Best Online Linux Terminals in 2026: Real Environments Compared
Running ls in a browser does not prove that Linux is running behind the prompt. Some online terminals connect to an Ubuntu virtual machine. Some start a short-lived container. Others implement familiar commands in JavaScript without a Linux kernel, package database, service manager, or real process table. All three can draw a convincing prompt; only the first two execute commands on Linux. That difference determines what you can practise. A command simulator may be enough to learn what cd d...
How to Open, Extract and Create RAR Files in Linux
Picture this: You’ve been handed SSH access to a client’s production server. Your job is to pull logs, create RAR Files in Linux, and bring them for analysis. Simple enough, until you realize the directory you need to archive contains hundreds of files, and the upload limit on the client’s portal only accepts archives under 50 MB. You could zip everything. But the logs total 200 MB uncompressed, and you need the archive to split cleanly into parts so each chunk uploads independently. That’s ...

Mastering Unattended Remote Desktop on Wayland: A Modern DevOps Guide
Introduction to the Wayland Remote Access Dilemma For developers and system administrators, accessing a remote Linux workstation or home server has historically been a straightforward affair. Whether it was X11 forwarding, VNC, or specialized RDP setups, the ability to jump into a machine that was left unattended was a fundamental capability. However, the transition to Wayland has significantly complicated this narrative. In many modern environments, Wayland prevents direct framebuffer acce...
