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.
TLP settings file Ubuntu: /etc/tlp.conf
Reload config: sudo tlp start
Check TLP status: sudo tlp-stat
Check battery: upower -i /org/freedesktop/UPower/devices/battery_BAT0

Drush is often described as Drupal’s command-line shell. That is technically correct, but it understates its value. Used well, Drush gives a business or agency team a repeatable way to inspect a site, target the right environment, run deployments, and document operational knowledge that would otherwise live in one developer’s head.

Importing a forum, spreadsheet, legacy CMS, or operational database into Drupal is not simply a matter of matching columns. It is a controlled data project involving content design, business rules, privacy decisions, testing, and launch planning.
There are a lot of resources out there on the internet. I just need to have my own overview where I can supply with my own notes. I really like the creative commons idea, where you attribute the author.

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).
Update 2022-07-14: kill kiod or kiod5 and then do jmtpfs
Update 2021-07-10: sudo aptitude install gmtp
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

Free Drupal themes can still be a good starting point, but the useful question has changed. In 2015, it made sense to collect attractive theme links and try them on small sites. In 2026, a business site needs more discipline: current Drupal support, predictable editing, accessible templates, fast pages, and a theme that another developer or agency can maintain without detective work.
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.

Exporting and importing Drupal 7 content types used to be a small site-building chore: install a theme, copy a few structures, move on. In 2026 it needs a little more care. Drupal 7 is now a legacy platform, so the right question is not only “which module can copy this content type?” It is also “how do we avoid breaking a live site, preserve what the business needs, and keep the migration path open?”
