What is DevSecOps? Everything You Need To Know About DevSecOps
Most people are familiar with the term “DevOps,” but they don’t know how to really utilize it. There’s more to DevOps than just development and operational teams. There’s an essential element of DevOps that is often missing from the equation; IT security. Security should be included in the lifecycle of apps.
The reason you need to include security is that security was once assigned to one team that integrated security near the end-stages of development. Taking such a lax approach to security wasn’t such a problem when apps were developed in months or years. The average development cycle has changed quite a bit, though, and apps can be developed in a matter of days or weeks. Outdated security practices like leaving security too late can bring DevOps initiatives to their knees.

Nibble Stew: The Meson Manual: Good News, Bad News and Good News
Starting with good news, the Meson Manual has been updated to a third edition. In addition to the usual set of typo fixes, there is an entirely new chapter on converting projects from an existing build system to Meson. Not only are there tips and tricks on each part of the conversion, there is even guidance on how to get it done on projects that are too big to be converted in one go.

Percepio Releases Tracealyzer Visual Trace Diagnostics Solution Version 4.4 with Support for Embedded Linux
Percepio announced the availability of Tracealyzer version 4.4 with support for embedded Linux. Tracealyzer gives developers insight during software debugging and verification at the system level by enabling visual exploratory analysis from the top down. This makes the software suitable for spotting issues during full system testing and drill down into the details to find the cause.
Version 4.4 adds several views optimized for Linux tracing, in addition to a set of visualizations already in Tracealyzer, and leverages Common Trace Format (CTF) and the widely supported LTTng, an open source tracing framework.

LLVM Adds A SPIR-V CPU Runner For Handling GPU Kernels On The CPU - Phoronix
LLVM has merged an experimental MLIR-based SPIR-V CPU runner that the developers are working towards being able to handle CPU-based execution of GPU kernels.
This new SPIR-V runner is built around the MLIR intermediate representation (Multi-Level Intermediate Representation) with a focus of going from GPU-focused code translated through SPIR-V and to LLVM and then executed on the CPU. The runner focus is similar to that of the MLIR-based runners for NVIDIA CUDA, AMD ROCm, and Vulkan, but just executing on the CPU itself. It was earlier this year LLVM added the MLIR-Vulkan-Runner for handling MLIR on Vulkan hardware.

Python Modulo in Practice: How to Use the % Operator – Real Python
Python supports a wide range of arithmetic operators that you can use when working with numbers in your code. One of these operators is the modulo operator (%), which returns the remainder of dividing two numbers.

Test & Code : Python Testing for Software Engineering 136: Wearable Technology - Sophy Wong
Wearable technology is not just smart consumer devices like watches and activity trackers.
Wearable tech also includes one off projects by designers, makers, and hackers and there are more and more people producing tutorials on how to get started. Wearable tech is also a great way to get both kids and adults excited about coding, electronics, and in general, engineering skills.
Sophy Wong is a designer who makes really cool stuff using code, technology, costuming, soldering, and even jewelry techniques to get tech onto the human body.

Librsvg's test suite is now in Rust
Some days ago, Dunja Lalic rewrote the continuous integration scripts to be much faster. A complete pipeline used to take about 90 minutes to run, now it takes about 15 minutes on average.
[...]
The most complicated thing to port was the reference tests. These are the most important ones; each test loads an SVG document, renders it, and compares the result to a reference PNG image. There are some complications in the tests; they have to create a special configuration for Fontconfig and Pango, so as to have reproducible font rendering. The pango-rs bindings do not cover this part of Pango, so we had to do some things by hand.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
