I like writing software, even if I don't get to do it much anymore. Kubernetes. Star Wars nerd, Expanse fan, dad, dork.

I wrote a little bit about how to do deployment updates without serving errors in #Kubernetes.
Since I don't have a blog, I'll just skeet (Note: was posted elsewhere Aug'22)
You have some pods, and maybe an load-balancer, too. You want to update the deployment. How to do this "best" in K8s today?

Release v0.1.0 - The First Release · agent-substrate/substrate
v0.1.0 Marks our first "real" release.

At SDCC my kid said the most gen-alpha thing I can imagine: Does Star Trek even still upload?

Every now and then I end up on NextDoor for something and I can't help but look around. It's just a cesspool of grumpy boomers complaining about life in California.
Please leave, there are lots of people waiting to live in your houses.
Sheesh.

Small trick for doing technical diagrams in Google Slides.
I often want more attachment points for arrows. It turns out that the 16-pointed star has a whole bunch, and you can change the point depth so it looks like a circle/oval.
I now use that instead of boxes or circles.

Best compliment I have received all week:
"I was reading some substrate mds and was pretty impressed that it sounded like it’s coming from a human"
They ARE coming from a human! We put a fair amount of work into them. They are "artisanal, hand-crafted docs", if you will.

I am happy to share a little thing we have been cooking up: github.com/agent-substr...
Problem statement: How can we effectively host a bazillion mostly-idle agents in a regular-sized Kubernetes cluster?
This is *demo-grade* software, but it shows some ideas.

There are things I can "disagree and commit" on, but NOT using the Oxford comma is not one.
To my dying day, I will keep reinserting it into any doc that gives me editor access.

"We are experiencing high demand, please try again later" on an airline's website is pathetic. Tell me you don't give a shit about your customers without telling me you don't give a shit about your customers.

Sadly, I will not be at KubeCon this week. To show all my kubernaut friends just how much I miss you, I have a small gift.
If you missed out on getting a deck of Exploding Clusters cards, well now you can play online.

Go easy on me, it's just a "free time" project.
Have fun!

A tiny hummingbird has made her nest in the dwarf satsuma tree outside my front door. Now I feel obligated to protect her from neighborhood cats. You should have picked a taller tree, mama bird!

I bought what I thought was a 12 foot loop of specialty cabling for $20. What I got was 12 INCHES.

When you find an interesting product online but it's just a little too expensive to YOLO, so you scour the web for reviews or comparisons or just the technical spec and find NOTHING...do you really want to buy that product?
The "locate a dealer" vibe is off-putting. I guess this one is not for me.

I can't tell you how much fun I am having, making Gemini and/or ChatGPT edit a picture of my house to change the color. We need to re-paint, and this is so much better than collecting paint cards from Home Depot.

Ok, to temper my enthusiasm -- did anyone thing "History of the World Part 2" was good? Brooks can often be hilarious but sometimes his humor comes across like an 11 year old boy.
Still, benefit of the doubt.
