LLMs can make mistakes, leak data, or be tricked into doing things they were not meant to do. Garak is a free, open-source tool designed to test these weaknesses. It checks for problems like hallucinations, prompt injections, jailbreaks, and toxic outputs. By running different tests, it helps developers understand where a model might fail and how to make it safer.

Want to play Windows games on your Linux system but not sure where to begin? Heard that some Linux distros are better optimized for gaming but don’t know which ones to pick? Don’t worry, here’s a guide to the five best Linux distros that make running Windows games smooth and hassle-free.

The good news is that gaming on Linux has improved dramatically in recent years. Besides the many native Linux titles already available, you can also play a huge selection of Windows-only games using compatibility tools like Proton (built into Steam) and Wine. In fact, nearly 80% of the most popular Windows games now run on Linux with little to no extra effort.

Now, technically, you can install almost any Linux distro and get gaming to work with a few tweaks. But let’s be honest, if you’re just starting out or you simply want something that “just works”, you don’t want to spend hours configuring drivers, gaming tools, and compatibility settings. That’s where specialized Linux gaming distros come in!

Longtime PyPy developer Antonio Cuni has a lengthy blog post that describes his talk at the recently completed 2025 CPython Core Dev Sprint, held at Arm in Cambridge, UK. The talk, entitled "Tracing JIT and real world Python — aka: what we can learn from PyPy" was meant to try to pass on some of his experiences "optimizing existing code for PyPy at a high-frequency trading firm" to the developers working on the CPython JIT compiler. His goal was to raise awareness of some of the problems he encountered: Until now CPython's performance has been particularly predictable, there are well established "performance tricks" to make code faster, and generally speaking you can mostly reason about the speed of a given piece of code "locally".

Adding a JIT completely changes how we reason about performance of a given program, for two reasons:

1. JITted code can be very fast if your code conforms to the heuristics applied by the JIT compiler, but unexpectedly slow(-ish) otherwise;
2. the speed of a given piece of code might depend heavily on what happens elsewhere in the program, making it much harder to reason about performance locally.

The end result is that modifying a line of code can significantly impact seemingly unrelated code. This effect becomes more pronounced as the JIT becomes more sophisticated.

Cuni also gave a talk on Python performance, which LWN covered, at EuroPython 2025 in July.

The file_operations structure in the kernel is a set of function pointers implementing, as the name would suggest, operations on files. A subsystem that manages objects which can be represented by a file descriptor will provide a file_operations structure providing implementations of the various operations that a user of the file descriptor may want to carry out. The mmap() method, in particular, is invoked when user space calls the mmap() system call to map the object behind a file descriptor into its address space. That method, though, is currently on its way out in a multi-release process that started in 6.17.

The Fedora project has posted a proposal for a policy regarding the use of AI tools when developing for the distribution.

You are responsible for your contributions. AI-generated content must be treated as a suggestion, not as final code or text. It is your responsibility to review, test, and understand everything you submit. Submitting unverified or low-quality machine-generated content (sometimes called "AI slop") creates an unfair review burden on the community and is not an acceptable contribution.

Talos is a specialist Linux-based operating system for running Kubernetes, an open-source system for automating deployment, scaling and management of containerised applications. Minimal, immutable and hardened, it does not offer any shell or interactive console; instead, all system management is done via remote Application Programming Interface (API) calls, where messages sent from a client application are protected with mutual Transport Layer Security TLS (mTLS) authentication. Talos also delivers atomic updates, thus maintaining the Linux and Kubernetes versions up-to-date. Talos is developed in the USA by Sidero Labs, Inc.
