> Welcome to this week's Linux Weekly Roundup. We had a full week in the world of Linux releases, many reviews will be ready next week.
> Ubuntu 22.10 Beta, Linux Lite 6.2 RC1, Linuxfx 11.2.22.04.3, and Bluestar Linux 5.19.11 have been released this week.
> One of the first things I learned about programming in the RPG II language was that field and variable names had to be six characters or less and they did not have to be pronounceable. I accepted this without question, as I was new to computers and figured that everything that had to do with computers was arcane and other-worldly. It wasn’t until I began work toward my computer science degree and was privileged to learn Pascal that I came to appreciate the value of longer identifier names, and of clarity of source code in general.
> You don’t have to have a computer science degree to use long field names in modern RPG. Even if your database files — physical and logical — have field names of six characters or less, you don’t have to use those short names ever again in RPG programs. It is my purpose in this article to show you how to use longer, more legible field names instead.
> Spectro Cloud, the Bay Area-based modern infrastructure startup, announced a new platform that promises simplified onboarding and management of edge computing devices running Kubernetes.
> Kubernetes v1.25 introduces the support for user namespaces.
> This is a major improvement for running secure workloads in Kubernetes. Each pod will have access only to a limited subset of the available UIDs and GIDs on the system, thus adding a new security layer to protect from other pods running on the same system. How does it work? A process running on Linux can use up to 4294967296 different UIDs and GIDs.
