I was on a call today that mentioned a blog post by Marianne Bellotti (author book "Kill it with Fire" 🔥) about writing some COBOL on IBM z/OS via ISPF, and it goes into detail about what I tend to condense into "Mainframes work differently than systems most folks are familiar with today."

Datasets, JCL, weird format requirements, and why can't I just create a file!?

And it's funny, I had a good chuckle at "JCL on first glance is a gobbledygook of all caps" 😂

Enjoy! https://medium.com/the-technical-archaeologist/hello-world-on-z-os-a0ef31c1e87f

Hello World on z/OS

Let me tell you … karma is a bitch.

As foretold by prophecy, LAPD used their "first responder" drones to spy on No Kings protests and anti-ICE protests: https://theintercept.com/2026/04/20/lapd-skydio-drone-surveillance-no-kings-protest-ice/

‘Reefer Madness,’ the P.S.A. That Backfired Spectacularly

The comically self-serious and outrageous 1936 morality tale, which warned the public about marijuana, became an unintentional parody and midnight-movie classic decades later.

My guess about the Kash Patel lawsuit is that its real purpose is to force the Atlantic to identify its sources and thereby give Patel, DoJ, and Trump new targets.
Today's winner of the Internet. Congratulations!

> Anthropic silently installed a spyware bridge [browser extension native messaging permission] on my machine

> The bridge runs outside the browser's sandbox at user privilege level [1], and Native Messaging hosts do not surface in any standard macOS process or permission UI […]

> This is the capability that Anthropic pre-stages on my laptop the moment I install their desktop application. Without telling me. Without asking me. Without offering me the chance to say no.

Anthropic secretly installs spyware when you install Claude Desktop — That Privacy Guy!

Anthropic's Claude Desktop silently installs a Native Messaging bridge into seven Chromium browsers, including browsers Anthropic's own documentation says it does not support, and browsers the user has not even installed.

That Privacy Guy!

It is very easy to vote in Virginia. We voted about a month ago. Both of us voted YES. If you live in Virginia it is important that you vote yes.

The most surprising thing is all of the lying flyers the Republicans are sending. Incredible they can get away with such outright lying.

Back to Huntley Meadows Park again today… It was a quiet day, both for people and birds, probably because of the heat (91℉; 33℃). But a wood duck couple was enjoying a swim, and a red-bellied woodpecker scored something tasty to eat. I also visited the owl basket nest, seeing one owlet in the basket and and adult perched on its rim.
