Get package.json version from CLI

Using NPM

npm info . version
npm info /my/npm/project/path/ version

Use the npm info command to point to the folder where your package.json resides.

Using Node

node -p -e "require('./package.json').version"

The -p argument prints the result and the -e argument expects executable JS to follow it. This one is also helpful for getting specific properties from any JSON file.

Git -Xours -Xtheirs arguments

Git provides a helpful argument to prefer one branch or the other to “clobber” merge conflicts:

git merge main -Xours
git merge main -Xtheirs

I always get confused what the “X” means. I always assume “X” means mark which branch to clobber. Like “X” out their branch. Or “X” out our branch. Please wipe this mnemonic from your brain!

“X” means “PREFER”

“PREFER” the changes in their branch (-Xtheirs) or “PREFER” the changes in our branch (-Xours).

Jeez!

Humans don’t know what they care about

If you hand over the management of your civilization to machines, you then lose the incentive to understand it yourself or to teach the next generation. […] Up until now, we put a lot of our civilization into books. But the books can’t run it for us. So we always have to teach the next generation. If you work it out, it’s about a trillion person years of teaching and learning in an unbroken chain that goes back tens of thousands of generations. What happens if that chain breaks?
