You're free to use whatever license you want for software you write.
The term "open source" has an actual definition, just like the term "free software" does. Both definitions say you can't restrict who can use the software or what they can use it for.
No, I mean that item number 6 of the Open Source Definition specifically states you cannot restrict the use of the software for any particular field or endeavor. That includes use in military applications.
If you have restrictions like that in your license, it's not open source.
I did tech support for a computer line that had Windows 95 on 8MB of RAM. It was pretty snappy for its time. Windows 3.1 flew on that hardware.
32MB of RAM on a PC? Only UNIX workstations and servers had that kind of luxury.
Better yet, who here worked IT when the Loveletter worm hit? Fun times.
A license that has restrictions like that doesn't meet the criteria to call itself "open source."
Also indexes. Once you've been bitten enough by off-by-one errors this actually becomes a pretty handy double-check.
Elon used to say he was going to found a Mars colony. I don't pay much attention to him so maybe he doesn't talk about it anymore, but it was a big thing maybe fifteen years ago.
Look up "rabbit starvation" some time. Rabbit's fine but you have to be sure your diet is diverse enough.
This story doesn't stand up to scrutiny.
Used to be that one in every five trees on the eastern seaboard was a chestnut. They weren't wiped out by logging - otherwise a lot more than just chestnut trees would have disappeared by now. Chestnut was a utility wood - good for building stuff but without the rarity and demand that plagued rosewood, ebony, and mahogany.
Did colonization kill the tree? Sure, but because cross-oceanic shipping introduced the blight, not because of any direct human activity.
In any event, if they're reintroducing chestnuts I'm getting a couple for my property. I ate my first chestnut in my 40s (in Spain) and I'd love to have some in my retirement.
Or we just don't like the taste. I'm not picky about what part of the animal I eat (except chitlin's... the smell put me off those forever). I'll eat gizzards all day. Chicken liver tastes like dirt to me.
Ditching the UNIX philosophy is a bad idea.
It's a very useful guideline. There are times when those rules should be broken - systemd may be one of those - but by and large the UNIX philosophy has served us well.
As far as dollar amount, probably some meal with my girlfriend. We don't do fancy but usually have one nice meal on a vacation.
But as a percentage of my income - something called Bonzai Chicken I ordered for $70 on my honeymoon back in the 90s. I made $7/hr at the time. I didn't know it had curry in it or that I was allergic to curry. I spent the remainder of my honeymoon sick as a dog.
