I use InteliJ IDEA for work when working on Java code. When the IDE doesn’t work, though, it’s incredibly distracting.
I had a problem where IDEA would not find a few auxiliary classes in my application. It would highlight them as errors in imports, and the search would find the source file, but technically not the class definition. I’d poke at the problem over a couple weeks, but I’d otherwise ignore it most the time until it seemed to be losing more and more of my classes, some of which I was actively modifying.
Re-importing the project’s Maven build didn’t fix it; re-cloning a brand new project didn’t fix it; and re-installing IDEA didn’t even work. Finally, I found IDEA’s config directories, and wiped those out to start over, and that cleared up the problem: I was able to find all my classes again.

Today, I’m knocking something off the TODO list: Ensuring a way to have local, non-shared shell initialization across workstations, while still sharing most the code.

Groovy is relatively intuitive for me: I can usually guess a method or operator and find it works as I had guessed.
Removing a key/value by the key
from a Map conveniently
eludes me though.
I always guess that I should be able
to minus a key from a Map
to produce a new Map
with that entry /value removed.
That doesn’t work,
so I needed to invent my own.
I still not sure how to practically
apply it everywhere though,
or if it’s even worthwhile.
In practice,
I always end up writing the findAll inline.
@Category(Map)
class MapMinus {
Map minus(Collection keys) {
this.findAll { k, v -> ! (k in keys) }
}
Map minus(Object key) {
this - [key]
}
}
use (MapMinus) {
assert [b: 2, c: 3,] == [a: 1, b: 2, c: 3,] - 'a'
assert [b: 2, c: 3,] == [a: 1, b: 2, c: 3,] - ['a']
}

I have MacVim installed
by Homebrew,
but MacVim still pops up sometimes to suggest an update,
and brew updates it as well.
After a year or 2 of this,
my "Open with…" menu
was littered with about 7 different versions
of MacVim dating back to version 7.4.
I figured I’d try to uninstall it,
brew uninstall macvim,
and see how many version I’m left.
The simple uninstall
confirmed that quite a few versions
of MacVim were installed,
and suggested the --force option
to remove them all, so I did.
That left mvim no longer working in the shell,
and fortunately,
all the MacVims had disappeared
from the "Open with…" menu as well.
Reinstalling it with brew install macvim
leaves me nicely with only one MacVim now.
I’ll have to see if they multiply again,
but now I’ll have this note to myself
on how to fix it.
