Belated Halloween Dance! 🎃
This is the first time that I've ever attempted this dance - I've seen it enough times that I got the general gist! But let's be real, it's terrible. 😄 I guess I don't care, because I had fun. Happy belated Halloween!

And so it begins! Is lifting the bar hard for me? Yes. Is my shirt inside out? Also yes. 😂 Am I going to be consistent, and steadfast in my ability to manifest what I want in life? HELL yes. 👏

hey @rockylinux.org 👋 We have been getting 404s for some of the Rocky mirrors today (and recently) in our CI. Usually a rerun fixes it, but I wanted to make sure you were aware, and if there is a status page we could refer to for future issues? Thank you! 🙏

When things are hard, we remember that we are responsible for ourselves, and the outcomes of our choices. Today I chose strength, and to prove to myself that I am still the strongest person that I know. With time (and protein!) you will see it too. I embrace darkness, but I choose to be a light.

It's about time we think more about our job shape. This is something I'm really excited about for #FluxFramework! Have you ever thought about the implications of your flag choices for binding? I made a little tool today (WIP) that can detect (and then predict) topology (binding) down to PU.

Developer tip - taking the time to write comments for the next day. If you are a gerbil, a monster, a three toed sloth, or a goblin that will die alone, make sure to be honest with yourself about that. 🧌

Da nananana na na na na Batman! 🦇
I got a really challenging build environment working today (took 11 hours 🙃) and then... new track adventure!
youtu.be/on8UcrpMy8c?...
Dirt tracks are slippery, but you can still have a lot of fun! This was 4x400 (4 miles) of a relaxed pace, 3 warm up/cool down.

What did I do for the holiday weekend? 🤔 Biked around for 15 miles looking for a track. I didn't find one, so opted for paved paths instead. I didn't hit the pace I wanted, but in retrospect, this was a good effort! I ran this at noon on Saturday, when it was in the 90s. 😎

I like the message that I imbue this song with - life experience stays with us, and we choose to have strength. Often that means doing things that are hard.

Today was my first interval workout - I found a dirt track and maintained a 5:20-6 minute mile pace for 12x300m. 💪

About 76 miles of biking and running since Tuesday. 🌞

For folks familiar with #SLURM- we are looking for a way to validate SBATCH directives. Slurm has --test-only but it does validation for flags *and* against a cluster, and they seem tied. In #Flux we can validate directives (via a directive parser) separately from resources (feasibility plugin). Ty!

This was 20 years ago. When we are young we often can't anticipate oncoming darkness. But we also can't anticipate our own resilience. What we come to realize with experience is that we are always in a mixture of light and shadow. It is a choice to not just see, but try to be a source of light. 🕯️

For the first time - user-space Kubernetes running under a Flux allocation on a production cluster. This is OSU and LAMMPS. This has been months of work and persistence. We got this working on an old kernel, and hugely strict security policy. Experiments and more details coming soon! 🥳
