Southern California is beautiful, but I especially love the tail end of "winter" right now when Burbank is flush with green 💚

Anyway, time to go home to Northern California ✈️ where it's also beautiful 😉

The computer history podcast I mentioned during a Q&A at #SCALE23x earlier was @adventofcomp.bsky.social

Episode 60 is where he digs into the early days of COBOL development

I hate AI slop code as much as the rest of you. Really.

But I also say this a lot: With every evolution of interacting with computers, the last generation will say "that's not real programming"

@brendan.fyi at SCALE wrote a whole talk about it! And how to approach AI assisted development ⭐

Looking forward to continued refinements as I get more feedback, I had some really great conversations today about more industries we need to bring open source to.

Open Source in Closed Ecosystems 
12:30 - Ballroom G
 In spite of Linux running on the platform for 25 years, the mainframe community is notoriously proprietary. Fortunately, in the past several years we've built a thriving open source community that subverts the status quo. Learn how we did it, and how you can too.

My talk at #SCALE23x is coming up today at 12:30!

I've worked with some great folks over the past several weeks to put the finishing touches on this one, and I'm really thrilled to give it for the first time here.

Course: DL11022G: z/Architecture Assembler Language. Part 1: The Basics - IBM Training - Global This course provides an introduction to the z/Architecture Assembler language. The course is designed to develop the skills appropriate to write and/or maintain programs and routines.

Great talk by Jon "maddog" Hall on developing an effective higher education curriculum so students learn to learn. But I'm here for the stories 😁

And his suggestions like how you miiiight want to have a clue about Assembly.

I want to dig into this gem this year: www.ibm.com/training/cou...

I've been vaguely unwell for the past couple of days.

To address this malaise, clearly I need to visit my cottage by the sea to take in the air.

(Alas, I do not have a cottage by the sea, and it's not the 1800s)

Presented to a group of college students this week who were better dressed than I was and have a smart casual dress code for events.

Being able to do a reasonable amount of arithmetic in my head has sure come in handy when my kids want to spend the whole drive home from getting haircuts hurling math problems at me.

Bottom of an Oliver 9 typewriter with 4 new replacement rubber feet on the 4 corners

I have replaced the 107 year old rubber feet on my Oliver 9 #typewriter via new rubber feet from: www.antikeychop.com/olivertypewr...

Getting the old feet out sucked 😂 required a drill and lots of scraping out old rubber. But it was needed, one of the old feet had partially broken off.

Live demos are good for discovering what your brain will selectively fail to retrieve under pressure.

Like command flags that you've been using for a decade+

"What are you doing?"

"Working."

"...you need to stop saying building Lego is working 😂"

But it's an IBM z16! And a Red Hat Lego set (via: coolstuff.redhat.com)

(I was actually diligently listening to an All Hands broadcast, but sitting still is not my forte)

Looking back, "I'll do it next week" for a half dozen big things wasn't the best time management strategy.

Had a bit of trouble printing the Paper Guide, even when we used glue on the plate, so MJ went with a big ole brim. That did it.

"Hey yeah, I wedged these in real good... But are they supposed to be free-moving?"

Yes. Oof.

One piece needs to be reprinted because it didn't survive extraction 😅

We Californians have complicated opinons about our governor, but it is delightful that he signed this on a BART car 😄

"Mom, Mom, Mom come look!" *furious giggling*

"OMG DON'T PUT YOUR UNDERWEAR ON THE CAT'S HEAD!"

"It's clean underwear!"

I mean, yeah, that's a plus.

Good morning 🥱

Basic Typewriter Restoration presents

NEVER USE WD-40

Basically everything on Richard Polt's website is pure gold, but specifically: site.xavier.edu/polt/typewri...

There are a ton of videos on YouTube, I've basically learned how typewriters work from Phoenix Typewriter (whose owner passed away recently and we're all poorer for it)

Listen, the man is a legend. He invented QWERTY! And put into production some of the first typewriters in the US!

Our 7 year old wants to play Minecraft on a computer now because the Java edition has different features and blah, blah, blah I wasn't listening because he talks about Minecraft a lot and I'm tired 😝

So he asked me for a Windows laptop 😱

I guess it's time to have The Talk 🐧 #linux

We bought silicone spatulas when the botched research dropped about black ones being bad.

I hate them. When I use them I can taste the silicone in my food. Yuck. No one else in my house has a problem with them.

Thanks to Reddit, it's a thing, like cilantro, only some of us are cursed like this.

There's a reason we don't make screws from plastic (PLA+) 😅

I appreciate the effort to make as much of this index #typewriter 3d printed as possible, but the mix of 3d printed hex screws and 3d printed holes? More than a couple stripped screws. Had to get out the pliers.

Our 5yo woke up at 5:45 with growing pains. Subsequent topics of conversation as I failed to get him to go back to sleep included:

Have you ever found a clam on a beach?

Can you show me a picture of a headless ghost?

If we made a Minecraft portal in real life, can we go in it?

😴
