Off to orlando for IBM TechXchange. I am speaking tomorrow! So if anyone is there come by and hear me talk about RHEL as a platform for developers! Tomorrow at 11am.
I'll be talking a few features but primarily i'll be showing you live how to use podman desktop for local development and then build a RHEL image mode system from the result. Unfortunately the TSA confiscated my chickens so i won't be able to sacrifice them before my demo. So i'll be working without a net. Pray for me. ;)
dnf is not always the sharpest knife in the toolbox ...

What #OpenSource and #SelfHost can do. Had an idea, discussed it here. Seemed to rhyme with people. Booked two domains. Created a landing page with #Jekyll and CI/CD from a #git repo on my #Forgejo instance. Created logo with #Inkscape. Added #letsencrypt certificate. Put it on my VPS (Virtual Private Server) running Red Hat Enterprise Linux, (#RHEL) where it is now served with #Nginx. Git repo mirrored to #Codeberg so all can join. In under 8h.
ARGH! Just discovered that one of my trusty older laptops (Lenovo X220 tablet) can't run #RHEL RHEL10/UBI10/CS10 because its i5-2520 CPU doesn't suipport x86-64-v3 
"Fatal glibc error: CPU does not support x86-64-v3" (Ref: https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/10/html-single/10.0_release_notes/index#architectures)
Noting that #Fedora up to 43 still works ok.
EDIT: Also discovered that since glibc 2.33 you can run the dynamical loader to tell you which x86-64 versions are supported by your CPU with the rather odd looking "/lib64/ld-linux-x86-64.so.2 --help"
Rising from the Ashes: How #AlmaLinux and #RockyLinux Redefined the Post-#CentOS Landscape
For over a decade, CentOS was the backbone of countless servers.
That stability came to an end when #Red Hatpivoted CentOS to a rolling-release model, #CentOSStream. Instead of offering a downstream, binary-compatible version of #RHEL.
This disruption created a vacuum, and the #Linux community quickly stepped up to fill it, and so were born AlmaLinux and Rocky Linux!

Symlinks and Hardlinks. If you're like me you know they both exist, but maybe aren't all that clear on when to use which? On today's Into the Terminal, we're exploring both, and talking through why you might use one vs. the other. Come join us! Noon eastern!
Time flies! Another Friday, another `dnf update` and reboot cycle on my 5 Red Hat Enterprise Linux (RHEL) servers.
(These are my private servers, that I update every Friday so that I have the weekend to fix things, if needed. So far it was never needed as updates JustWork™)
UPDATE: All machines updated, rebooted and tested. No problems found, weekend can start!
The August 8th, 2025 Jail/Zones Production User Call is up:
We discussed surprises on the Power architecture, #RHEL to #FreeBSD migration with up to a 40% performance increase, the approval and abilities of the executable jail.conf Review, strategy for automating disaster recovery on FreeBSD hosts, jail ABI backwards compatibility, t-shirt ideas, and more!
"Don't forget to slam those Like and Subscribe buttons."
Did modernize my Ansible role to provision virtual machines on Proxmox via Kickstart in my homelab and added RHEL10 compatibility.
Did it in a peer-programming style with the friendly 
Claude. That worked rather well, especially for the documentation, restructuring and analyzing/solving issues together.
It wasn't without it's problems but the speeup was crazy. It would have easily taken me double the time, if not more, to do this alone.
The Ansible code in the end was absolutely amazing. Robust, idempotent, error tolerant and well structured. With proper guidance, AI can be a great speed multiplier.
New (long and nerdy) blog post: "Be the LetsEncrypt in your homelab with step-ca" at https://jan.wildeboer.net/2025/07/letsencrypt-homelab-stepca/ where I explain my homelab setup with its own CA (Certificate Authority) on RHEL 10 (Red Hat Enterprise Linux) machines.
Replies to this toot will show up as comments on the blog post.
Who is "we" that selected #opensuse Is this selection process public? I like to read it.
Can you please provide a source for #RockyLinux and #AlmaLinux being based on #RHEL?
I understood both are based on CentOS Stream which is based on Fedora.

Seems #RHEL, Red Hat Enterprise Linux, is available for #WSL nowadays. Good for those doing corporate linux development while stuck to windows laptops. Most corp developers that is.

@hellomiakoda granted, #Snap is a "good idea, but horribly executed" and @ubuntu trying to hamfist it down peoples' throats.and being anti-#Flatpak didn't sit well for all the right reasons!
Even though EPEL is primarily used downstream by RHEL, @centos, @rockylinux, and @almalinux, it's actually part of the Fedora Project.
If you benefit from these packages, especially for your day job, consider contributing through package maintenance!

@gangrif @almalinux I ran #RHEL 9 that way for several years before switching to #unraid. I’d love to go back to #ansible running everything. But there’s something tempting about a full blown hypervisor under the hood that appeals to me.
