I love school. I love computers. I especially love helping people at the venn intersection of both.
Also @millia13 for more varied content.

@UnixToolTip https://t.co/tzECVTYrLz might be better.

@usgraphics Drop, before they faded away, had a really nice Noctua keycap set. If anybody's into that sort of thing.

@TracketPacer Where'd you get the DNS one?

[David Millians @k12_sysadmin]

Google's authenticator is a little simpler than Microsoft's- it's just plain and simple codes. Preferable. There are also others. Whichever you pick, find out how to back it up, and get backup codes for the account in case you lose your phone.

Activate multifactor authentication (MFA) in your TRS online account at https://t.co/EKzYPjh0df! You may choose authenticator apps such as Google or Microsoft’s Authenticator. Visit our website, click on Manage My Account --> Account Security Information --> Multifactor Authentication and make a selection.

@usgraphics I've got that in old old stock! Still works well.

@CShamis @usgraphics When I refurbed the bathroom from my 1920s house, there were about 3 pounds of blades behind the cabinet. It was almost up to the slot. A blade a week adds up.

don’t use flat twisted pair cables unless they’re never gonna bend lol

If you are a geek of a certain age, you are sad today. Those Byte covers were the absolute best.

[70s Sci-Fi Art @70sscifi]

RIP Robert Tinney (November 22, 1947 – February 1, 2026), the artist famous for his playful covers for Byte magazine, a hobbist magazine that ushered in the microcomputing age from the mid-70s through the 90s. I'm honored to have included his work in my own art collection.

There is no protocol like it in the world, because it was created in a different one. And every other world died.

SMTP.

Email is the final gasp of the original dream of electronic sovereignty. Of a federated world of peer communication. It's the last one. The final protocol.

[David Millians @k12_sysadmin]

@thehelpdeskgirl Congratulations! Finding your own path is the most important thing since we HAVE to work. Might as well make it fun.

We've lost common sense in infrastructure automation.

I've been implementing Azure infrastructure solutions for enterprise customers for years. Thousands of servers. Security baselines. Compliance monitoring. The real stuff.

Out of all the automation I've built and delivered, I can count on one hand the cases where an AI agent actually made sense. One hand.

The rest? Scripts. Queries. Scheduled tasks. Deterministic logic that does exactly what it's supposed to do, every single time, at a fraction of the cost.

Yet everywhere I look, people are wrapping basic automation in agent frameworks. Diagnostic settings rollout? Agent. Tag compliance? Agent. Resource Graph queries? Somehow, also agent.

Why? Because agents are the shiny new thing. Because it looks good on a slide deck. Because nobody wants to present "we wrote a PowerShell script" at the next team meeting.

Let me be clear: learning new technology is great. Experimenting is great. But shipping unnecessary complexity into production because it feels modern? That's not engineering. That's ego.

Every agent you deploy where a script would do is:
→ More cost (tokens aren't free)
→ More failure modes (now you're debugging AI behavior, not logic)
→ More operational overhead you'll be dealing with for years

Infrastructure automation is about reliability and predictability. Most of these tasks have known inputs, known outputs, and known logic. That's the opposite of where agents add value.

Agents belong where you need genuine reasoning over ambiguous, dynamic problems. Not where a foreach loop gets the job done.

Think before you architect. Common sense still applies.

@SwiftOnSecurity @lymanstoneky My wife got it after I had shingles. On balance, I think you want it ASAP, because while she had some discomfort after 2nd, she didn't wake up thinking she was having a heart attack, or feel like stabbing people for 3 weeks straight like I did.

[David Millians @k12_sysadmin]

@thoroughlysolty @usgraphics affirmative.

[David Millians @k12_sysadmin]

@thoroughlysolty @usgraphics Suspect that's a right-hand drive dash.

@WhoWillRickWill @SwiftOnSecurity The only problem with this site is their abjectly foolish take on the most wonderful apple ever, the Arkansas black. Crisp, tart, just sweet enough. You want to get the ugly ones- if they're buffed and polished, they're not as tasty or as crisp. Pie heaven!

[David Millians @k12_sysadmin]

@NathanMcNulty The problem we keep having is background things like some edge component that do require it but there's no way to put one in and satisfy the requirement. Very difficult to ascertain what's the issue.

[David Millians @k12_sysadmin]

It's been a while since we've had one of these, but #Google account authentication isn't working right for us. And a whole bunch of other people too. #googledown

[David Millians @k12_sysadmin]

@bettersafetynet @eligaultney With ios26, it's becoming a bit more OS X-like, especially with preview and files, so I'd wait to play with it after it's out. To be honest, I'm not sure I like that- it is a very nice device for people who aren't really PC savvy.

Attackers don’t exploit what you didn’t know. They exploit what you didn’t prioritize.
