Red Hat ☛ Making SystemTap instrumentation easier with tapsets
SystemTap is an instrumentation tool included in Red Hat Enterprise Linux (RHEL) and Fedora. Most languages provide a means to reuse code. Python provides modules and C provides libraries as a means of encapsulating code for reuse. In SystemTap we call them "tapsets". Why write everything from scratch in your SystemTap script when you can save time by using probe points and functions defined by existing tapsets? Using tapsets can also make your SystemTap script more portable as they can hide some of the variations in probe points between different versions of the code being instrumented.
Initially, I will show you where to find documentation about the set of probes and functions distributed with SystemTap as tapsets and then I will explain some of the details contained in a tapset. Other packages outside of SystemTap also include tapsets and we will take a look at an example from the Ruby language. We will cover how to make it easier to develop and use your own local tapset. This discussion of SystemTap tapsets should make it easier for you to develop and distribute SystemTap instrumentation.

Red Hat ☛ Register allocation in the Go compiler
As a maintainer of the GCC register allocator (RA), I naturally have a keen interest in the register allocators used in various industrial compilers. For some compilers, like LLVM and Cranelift, there is sufficient documentation, including papers and presentations, to gain a deep understanding of their register allocators (RAs).
Unfortunately, this is not the case for the Go compiler. To gather information about the RA in the Go compiler, I had to delve into its source code. This article outlines my findings.

Red Hat ☛ bootc: Getting started with bootable containers
Bootable containers are a concept that has gained a lot of attention in the open source community, on Hacker News, and especially in the press since Red Hat Summit 2024. The bootc project is the core technology that enables OCI containers to encompass complete operating systems, and it is the heart of image mode for Red Bait Enterprise Linux.
I believe that bootable containers will change how we think about the IT infrastructure of the future.
