comment How can I enter unicode characters on KDE?
@Gilles for me personally, it's usually about testing software I'm developing. This means I usually don't need the full gammut of characters, because usually fixing one wide character bug will fix the others. At the same time there is some need for variety in testing. The hunt and click option is probably the best, I don't have to type these characters frequently (thus don't have an identified subset), and I don't want to generally spend time going to a website if I don't have to find their codes.

and how does one enable the compose key? and how does one find these preconfigured combinations?

comment How can I enter unicode characters on KDE?
it appears I have to keep holding down ctrl+shift, but when it inserts it it also leaves the u2197 in the text area... so I'd have to delete that.

comment foolproof way to detect if java process is running
Build a health check into the application. Spring actuator has some good stuff, or at least will give you an idea. Your app could be running according to the os but not responding. App providing a health check could catch that in addition to it catching dead app.

comment How do I recursively check permissions in reverse?
hadn't looked at this in a long time, but I think I just realized why I had problems with it. it looks at the path you give it, so if you do namei -l file you'll just get that permission. namei /home/user/file would give the listing from root.

@Tasos it may be easier just to say "ensure oracle is started first" a la vagrant up oracle && vagrant up distributed

comment Switch Maven version after installing from jpackage?
that's kind of what the question was about, I couldn't figure out how to make alternatives do this honestly. (my first hack was just to modify the path)

comment Switch Maven version after installing from jpackage?
I think something else is pulling in maven haven't checked what. This is an entirely new image, built from vagrant. 3.0.3 is just enough in our case.

comment grep print relative file path when doing a recursive search
this should be more efficient than xargs, but accomplishes the same (including the too many args problem) find . -name 'pom.xml' -exec grep -3 'org.hibernate' '{}' +

comment grep print relative file path when doing a recursive search
this is the default behavior, it does not give the relative or absolute path, I can't tell the difference between one pom.xml and another with this (or maybe this option is ignored...) . Also this is not in my man page... are you sure this is for a freebsd grep and not gnu grep?

comment Airdrop compatible
for varying defintions of drop in... samba isn't exactly the only part needed for drop in on windows network sharing, but yeah, something I could use to basically do that. I of course, assume(d) that /someone/ is working on such a thing, though perhaps no one is.

comment Setting environment variables at runtime in KDE4
No it is not possible to update a running programs environment. It is possible to start a new shell with the new environment. @Gilles I suspect if you remove the KDE aspect this is a duplicate... do you know?

comment What is the different bash per terminal session for Konsole?
@Jim I would say that, no bash does not run separately from the terminal, the terminal spawns a new bash process. If you want to share a bash process between tabs, you'd need something like tmux or other terminal multiplexer.

comment Efficiently delete large directory containing thousands of files
using + instead of \; would make this faster as it passes more arguments to rm at once, less forking

comment Efficiently delete large directory containing thousands of files
if you're going to use exec you almost certainly want not use -ls and do find . -type f -exec rm '{}' + + is faster because it will give as many arguments to rm as it can handle at once.
