[Technology] quotes

Another good reason to encapsulate bash variables in quotes:


If you have multilined data that you're going to echo, the quotes will preserve the newlines.

            $ DATA="foo
            bar";
            $ echo $DATA
            foo bar
            $ echo "$DATA"
            foo
            bar
            $
            

The first reason I tend to think of is so spaces in file names aren't mistranslated as separators between arguments.

            $ FILENAME="foo bar.txt"
            $ ls -l $FILENAME
            ls: cannot access foo: No such file or directory
            ls: cannot access bar.txt: No such file or directory
            $ ls -l "$FILENAME"
            -rw-rw-r--. 1 user group 0 27. Jul 18:03 foo bar.txt
            $
            

[Technology] GNOME, missing features, and screenshots

I have been taking a lot of screen shots for a  project recently and was wondering why they weren't going into my screenshots directory.  Now I know why.



https://marteydodoo.com/writing/2013/12/15/saving-screenshots-different-directory-gnome-3/



Basically gnome-shell now handles it (which is fine) but doesn't provide an option for a directory other than your GNOME Pictures directory (not fine).   I'm not really sure why people would want to have their default images directory littered with screen shots, but whatever.

Over-riding Screenshot Keyboard Shortcuts

So, I went to Settings > Keyboard > Shortcuts

Title	Command	Keys
Screenshot	gnome-screenshot	PrtSc
Screenshot of window	gnome-screenshot -w	Alt-PrtSc
Screenshot of region	gnome-screenshot -a	Shift-PrtSc

For reasons I haven't explored yet, pressing Shift-PrtSc once doesn't trigger it, but instead sounds a bell.  Holding shift and tapping PrtSc twice quickly does, though.

Changing the Default Save Directory for Gnome Screenshot

The second half is then to make gnome-screenshot save it where I'd like it to.  Running it in interactive mode (gnome-screenshot -i) doesn't seem to give me an option on where to save it.  So, instead, I turned to gsettings.



$ gsettings set org.gnome.gnome-screenshot auto-save-directory "/home/myuser/path/to/my/screenshot/dir"

$ gsettings set org.gnome.gnome-screenshot last-save-directory "/home/myuser/path/to/my/screenshot/dir"



I don't think I need to set the second one, but I did so out of laziness.

Write a script that lets me process my screenshots

A lot of my screenshots are fine as JPGs, and save me a lot of disk space that way, so I wrote a small bash script that uses ImageMagick's convert and my 'splitalbum' to further organise them.



In the interest of getting me to publish more of my work, I automated turning little projects into tarballs and web pages and uploading them.    Here is 'Process New Screenshots', quick and dirty.

[Technology] More people access the Internet in China than on computers

I find that strange.



I like having a smart phone, because it helps liberate me.  I don't need to be tethered to my desk in a seated position, and I won't get super-involved in digital tasks, if I'm using my smart phone.  I can take it and just do a lot quickly and get it out of the way and resume enjoying the out doors.  Yay!



However, for doing almost anything particularly interesting with the Internet, I want a computer.  I want to be able to type efficiently.  I want to be able to see things at a larger scale.  I want to be able to be able to have multiple things open and go between them (I mean like two things for easy cross-referencing).



I'd rather get rid of my phone than my computer, I think.  The computer is a bit limiting geospatially, but he phone limits everything I could want to do digitally.
