Scientists Discover a Strange Global Pattern in The Way Humans Walk

Suppose you're wandering around a space without any particular destination in mind – exploring a park maybe, or ambling across a music festival site.

Voyager 1 is now so far from Earth that a signal traveling at the speed of light takes more than 22 hours to reach it — so when engineers send a command, they can wait nearly two days to know whether the spacecraft responded | Space Daily

Voyager 1 is now so far from Earth that a signal traveling at the speed of light takes more than 22 hours to reach it — so when engineers send a command, they can wait nearly two days to know whether the spacecraft responded

Sending a command to Voyager 1 is closer to mailing a letter than placing a phone call. The probe, launched in September 1977, is now roughly 16 billion miles from Earth, heading away from the Sun at roughly 38,000 miles per hour. In November 2026, Voyager 1 will become the first human-made object to pass […]

A security researcher says Microsoft secretly built a backdoor into BitLocker, releases an exploit to prove it

According to the researcher, YellowKey appears unusual for a previously unknown security bug. Nightmare-Eclipse explained that the flaw can be reproduced by copying an attached "FsTx" folder...

My wife left me because of my obsession with Linkin Park. But in the end, it doesn't even matter.

This is going to be slightly odd.

Back in my prehistoric days, I was a mainframe COBOL programmer. The dev environment I used was called CA/ROSCOE. It had built-in version control. Whenever you saved a file, it kept copies of the previous saves. I can't remember the exact command, but it was like

OPEN <filename> -1
or
OPEN <filename> -4

To get the previous versions.

Git, jj, hs and the like are far more complicated than I need.

It's there something that just saves/retrieves versions?
