Red Hat Official ☛ Secure cloud bursting: Leveraging confidential computing for peace of mind [Ed: Red Hat promoting back doors and surveillance mislabelled as "confidential"]
When using the public cloud there are always challenges which need to be overcome. Organizations lose some of the control over how security is handled and who can access the elements which, in most cases, are the core of the company's business. Additionally, some of those elements are controlled by local laws and regulations.This is especially true in the Financial Services and Insurance Industry (FSI) where regulations are gradually increasing in scope.

Red Hat ☛ Use bootc logically bound images to deploy a Kafka cluster
Logically bound images are a recently added feature in bootc that allows any container image to be managed directly by bootc. One of the many benefits this provides is simplified system management. An application image can be "bound" to a bootc operating system image as part of the bootc container build.
This simplified system management would have been useful for a project I previously worked on. The project was a large web application composed of dozens of microservices running in a Kubernetes cluster. These microservices primarily used Kafka to communicate. Our Kafka instance was also deployed in a Kubernetes cluster using the
amq-streamsoperator.The operator made the deployment and management of the Kafka cluster simple; however, keeping the cluster stable was a constant battle. One of the main issues was due to Kafka's heavy memory requirement. 32GB of memory is the minimum recommendation for a single Kafka node with a minimum of 3 nodes. Due to the cost, our Kubernetes nodes were not sized to accommodate this large memory requirement. We likely could have leveraged many of the newer Kubernetes features to stabilize the cluster; however, I wonder if it would have made more sense to run each Kafka node directly on a virtual machine (VM).

Red Hat ☛ How to track file descriptors with Valgrind
This article describes the new file descriptor related features recently added to Valgrind and explains how to use them to track the file descriptors that your program is using or, more importantly, misusing.
Valgrind was able to track file descriptors for a while. But my colleague Mark Wielaard and I improved this feature and turned all file descriptor operations into events, which allowed Valgrind to create errors on misuse that can show where the operation occurred, made them suppressible, and can be reported in different formats.
What is Valgrind?
Valgrind is an instrumentation framework for building dynamic analysis tools. The tool can detect various memory management and threading bugs. To be able to detect the bugs, Valgrind decompiles, instruments, and recompiles your code to intercept syscalls, signals, threading, and etc.
The most used Valgrind tool, also used by default, is Memcheck, which detects inaccessible or undefined memory usage. The other tools are Cachegrind, a cache profiler; Massif, a heap profiler; and Helgrind, which is a thread debugger and the special none tool (which didn't report any errors before).
