Yeah, especially in peace time. When war heats up and resources get scarce, you use the cheapest thing that does the job. But in peace time you feed your military contractors to keep them happy and to keep them researching and developing so you don’t lose out on modern technology development.

(For clarification, with “war time” I mean “being in a war that actually threatens the country”. The US hasn’t been in a war like that for a very long time. They’ve essentially being in “peace time” while having military training and testing facilities in the middle east.

You can not change history for any published changes - like I said, doing so makes your repository incompatible with any other clone.

That’s the same on Git.

10 years ago I got into RC planes for a summer, and me and the guy were talking about how ridiculous it is that the milirary is spending so much money on simple drones, when they could just strap some explosives on a cheap hobbyist RC plane/drone for a fraction of the price, and just create swarms of them.

The technology had been widely available for some time already back then. Turns out, it was just lacking a war to do so.

(Just to be clear, we were all anti-war in general, this was just idle speculatiok back then. But if our country was attacked at that time, I’m sure some of us would have ended in a newly created drone force like what happened in the Ukraine.)

Looks like Mercurial can change the history just fine using the hg command. You just need to enable it first.

Git can also be configured to disable history rewrites.

So the difference between git and hg really just comes down to the defaults.

I got weirdly invested in this, and by the end I was kinda happy that it was “just” a bug in the tooling and not anything actually malicious.

Android runs an only slightly modified Linux kernel, and yet the OS requires much less from the user than e.g. Windows or MacOS.

Chromebooks run a bog-standard Linux kernel and the target audience is kids.

My car’s entertainment system runs a standard Linux kernel, and the UX is so cut down that PC expertise really doesn’t matter when using it.

MacOS and iOS, two systems known for their ease of use, both stem from BSD, which comes from Unix.

The kernel has nothing to do with this.

In fact, the only mainstream kernel used in user-facing operating systems that doesn’t “come from Unix” is Windows. Everything else is derived either from Linux or BSD, which both are derived from Unix.

There isn’t even a mainstream phone OS anymore that doesn’t “come from Unix”.
