If privacy matters for you, you probably want to remove all EXIF metadata and anonymize your photos before you upload them.
yay exiftool
or
sudo apt-get install libimage-exiftool-perlTo display all EXIF information run
exiftool image.jpgTo remove all EXIF information from the image you run
exiftool -all= image.jpg
or
exiftool -all= *.jpgsome camcorders still record in 1080i 50 – this sucks hard.. in order to get rid of all thoses lines we need to deinterlace..
most applications like vlc or handbrake do a really bad job but there is a solution to this problem: ffmpeg
#!/bin/bash
for f in *.MTS
do
echo "DeInterlacing file: $f"
ffmpeg -i ${f} -vf yadif=1 -acodec ac3 -ab 192k -vcodec mpeg4 -f mp4 -y -qscale 0 ${f}-deinterlaced.mp4

well…
if you prefert to deactivate your wifi APs during the night there is an easy solution.
for most architectures there is a package called “wifi-schedule”
if for some reasons you are out of luck and this package is not in your versions repository don’t worry.. just set up a cronjob – this basically does the same thing.
00 00 * * Mon,Tue,Wed,Thu,Fri /sbin/wifi down
00 02 * * Sat,Sun /sbin/wifi down
00 06 * * Mon,Tue,Wed,Thu,Fri /sbin/wifi up
00 09 * * Sat,Sun /sbin/wifi up
this will disable your wifi in the middle of the night and reactivate it in the morning (different settings for businessdays 😉 )

#!/bin/bash kdesudo --comment "Dieses Programm benötigt Administrator Rechte" -d -i /usr/share/icons/breeze/places/22/user-identity.svg $1
i place this script in /usr/bin  and name it mysudo
i can then run a program with “mysudo script.sh” and instead of the whole path and the script name in the title AND the description it will look like this:

closure-compiler is part of every modern linux distribution. if it’s not installed hit “sudo apt install closure-compiler” in a terminal and press enter 🙂
to minimize your js file you can now write:
closure-compiler --js game.js --js_output_file game.min.js --language_in ES5 --compilation_level SIMPLE_OPTIMIZATIONS
this will minify your javascript file named “game.js” and store it as “game.min.js” in the same folder
the –language part makes sure that it runs through (in my case) even with some “reserved” names as custom variable names..  (i am using the phaser framework and “static” for example is a common (otherwise not allowed) name for an attribute)
using advanced_optimations instead of simple_optimations would lead to a more obfuscated output but is not working properly if you include several other js files because it’s heavily renaming everything – starting with classes, methods, attributes, etc.
