comment Lock screen after blanking with gnome-screensaver and XFCE
Rereading your question, I realize this probably doesn't answer your question as it works from command line only.

comment Lock screen after blanking with gnome-screensaver and XFCE
I am unfamiliar with xfce, but does qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock work (kde version)? on Gnome you use qdbus org.gnome.ScreenSaver /ScreenSaver Lock. You may have to type qdbus | grep -i screensaver to find your specific variation.

comment A clever way to defragment a FAT filesystem?
I would go for your first option if space isn't an issue. I would create a clean filesystem in a large file that is loop-mounted. That way you get the opportunity to check the result before overwriting the stick.

are you familiar with the commands cpulimit and timeout?

In my use case the killing is not desired.

comment Bash script that automatically kills processes when CPU/memory usage gets too high
First monday of the month and my PC is checking a (slow'ish) RAID6 set. CPU load easily peaks above 8 because it is constantly waiting for disk IO from this RAID set. Nothing wrong, system is still very responsive. Your script would kill my firefox which uses only 3.6% of the available 400%. Just saying you may be hunting for ghosts with this script. BTW: your system will not get damaged because of high load and when memory runs out, the kernel will do a semi-educated guess on which process(es) to kill.

comment reading from a file and changing its pattern into an array?
Set up key authentication on the Cisco boxes. It is a lot of work the first time, but once it works you can easily (and still secure) log on to the machines.

I wasn't aware of that, you should update your question to make it more specific.

comment How to build AVR cross-compler under Gentoo Linux?
Distributions are pretty much a personal thing to choose. In my opinion Gentoo is brilliant for learning all the ins and outs of GNU/Linux. I don't like Fedora and OpenSUSE because these are pretty much the test and play yard for RHEL and SLED. I personally am not fond of rpm-based package managers. I had couple bad experiences in the past, probably these are solved during the past 15 years but never really tried them again. I switched to Kubuntu because of the ease of its use and the KDE interface is a bit like the Windows interface that I'm familiar with.

comment How to build AVR cross-compler under Gentoo Linux?
These kind of messages are, amongst other things, the reason why I switched distributions couple years ago. Gentoo is brilliant for leaning Linux, but it can be a pain when you want things to just work (after installing updates).

comment Why does “chmod 1777” and “chmod 3777” both set the sticky bit?
You are proposing a potentially risky operation.The combination sticky bit and rwx permisions for all is bad practice. Anybody can change and execute the file and the s-bit allow switching to root user without pasword.

comment Use desktop speakers over SSH from laptop
Pulseaudio can route audio over the network. wiki.openwrt.org/doc/howto/pulseaudio I had it working many-many moons ago, but I changed hardware and it is no longer required for myself. I know it exists, I don't know how to implement it. Hence a link that I think is useful in a comment, rather than a full blown answer.

comment How to truely install a tar.gz file on Linux - how to manage manually-installed (or standalone) applications?
To elaborate on the eclipse example, if you are running on Debian, you don't have to search for *.(deb|tar.gz) files. Simply type sudo apt-get install eclipse to get it installed from repositories. It will receive automatic regular updates too and it will show in your 'Start'-menu. Always first search repositories, before manually downloading and installing software eg.: apt-cache search chrome returns (a.o.) chromium-browser which is the open source version for chrome. Make a choice either sudo apt-get install chromium-browser or install Chrome from its own archives.

comment How can I get Apache2 in OpenSUSE to map /srv/www/htdocs/index.php to localhost?
"what is changing the document root to point somewhere" => The Apache2 configuration is. You can find it in /etc/httpd. What files are in that directory? If there is a httpd.conf, then append it to your question.

comment Missing 32 bit library on a 64 bit Linux install
@jordanm your hint put me on the right track, thnx! I executed $ sudo apt-get install libgtk2.0-0:i386 libxtst6:i386 and Eclipse now successfully runs. You should consider writing an answer.
