IBM's ancient #training #film resurfaces like a relic from the digital Stone Age, desperately trying to keep its secrets away from the prying eyes of the 21st century 😂🔒. An archaeological masterpiece for those nostalgic about punch cards and #mainframes 📼💾.

Happy #Ubuntu 26.04 LTS release day!

Check out the latest when it comes to #mainframes specifically by visiting this blog post from the great Frank Heimes:

https://ubuntu-on-big-iron.blogspot.com/2026/04/blog-post.html

Somewhere, right now, a developer is sorting 400 COBOL cards off a computer room floor after a late night of keying. Nobody wants to look at it. Nobody cares.

But we do.

It concerns #AlpineLinux the same as it concerns every other Linux-based operating system that has a package management utility that talks to a public WWW site.

As I said at https://mastodonapp.uk/@JdeBP/116156019252249071, and as @RunxiYu has also said, the statute as written covers all such systems. (It's an Act now, by the way, not a Bill.) Alpine Linux has a covered application store.

Here, for example, is what 'publicly available internet website' apk as the 'software application' uses to 'facilitate the download' of the third-party rustc 'application' from the 'store' in Alpine Linux on the aforementioned #mainframes used by the aforementioned naughty 16-year-olds in #California:

https://dl-cdn.alpinelinux.org/alpine/v3.23/main/s390x/

Yes, #CaliforniaLaw as written is this expansive. Yes, the legislators did not even consider how the BSDs and Linux-based operating systems work. None of the objectors apparently even mentioned how these work.

@montyontherun

The definitions are broad, so to quite an extent they would. There are users, who have accounts, on general purpose computers, and run applications.

The only hope for #mainframes seems to be that they likely don't have things that fit the definition of a 'covered application store'.

But they might; especially if the mainframe is nowadays running a Linux-based operating system.

http://linuxvm.org/info/distros.html

#Debian and #Ubuntu have package repositories for s390x, for example. Such a repository is a 'publicly available internet website […] that distributes and facilitates the download of applications'.

Here's one way how the naughty 16-year-olds in #California would download rustc onto such a mainframe with no #AgeVerification, for example:

https://packages.debian.org/trixie/s390x/rustc/download

Hilarious sentence from Josh Tyrangiel in an essay for the March Atlantic:

“Mainframes are like Christopher Walken: They’ve been going nonstop since the 1960s, they’re fantastic at performing peculiar roles (processing payment payments, safeguarding data), and nobody alive really understands how they work.”
