In the old days we all had CD-drives, but most modern computers these days don't have an optical drive. This makes things even more efficient, because you need to think smart. Some people choose to have an external optical drive, but why all the hassle when you can have a bootable USB or a bootable partition on your harddrive. There ar many guides on the internet, how to get that done manually. Again, why the hasse when we have UNetbootin, the perfect software for booting your favorite ISO's from your harddrive!
My random notes regarding screen capture. The screen capture is not hard, and it is not hard to have one source of audio like the microphone. The hard part is to have multiple audio sources, like the microphone and the system sounds.
I use Cheese for the built in webcam capture. Here are the random links:
TLP is an advanced power management tool I use for my laptop that runs Linux. I have not tested the different settings, but it seems that the battery time is increased compared to not running it. :-) I only use it in battery-mode. There are some extra features for Thinkpad laptops.
Appending MOV files efficiently can be a challenge. The only "safe" and easy way without destroying the video or the sound is done by using Avidemux which is a free video editing tool for Linux.
Here is my modified image-convert bash script used for the appending all .MOV files in a folder and have the full video ready for editing in the Avidemux graphical user interface (GUI).
It can be a challenge to mount your Android phone (MTP device) in Linux if you have some strange files from your old Iphone. I needed to do it the hard way.
You need to install mtpfs and use this command: sudo mtpfs -o allow_other /media/android-device
Holy molly. I thought Garmin would provide a fancy and "updatede" procedure for uploading and/or extracting data from the fancy Garmin 910XT... but no. You need to search for a while before you find the gold. First I thought you could find a garmin connect tool or plugin for Firefox, but that failed completely. Then I narrowed down my search to "forerunner 910xt linux" (without the quotation marks in google). I found some sites that suggested to download a lot of python stuff and get things directly from Git.
