On rooted devices you can use the popular BusyBox app to set up BusyBox into /system/xbin and add this path to the default shell path.
On non-rooted devices it's a bit more complicated. Usually you can put your own stuff into /data/local/tmp and this is what I opted to do.

The process is quite simple:

1. Get an API key for the YouTube v3 Data API.
2. Query the https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername={user_or_channel_name}&key={your_api_key} url and substitute the channel name and api key with the proper values.
3. Query the https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&playlistId={playlist_id}&maxResults=50&key={your_api_key} url and substitute the playlist ID with the ID of the "uploads" playlist (fetched with the prev. query) and your API key. The result will contain max. 50 videos, but if it's so, there'll be a "nextPageToken" value that you can add to the URL in the "pageToken" parameter and request the next 50 videos, etc.

To recursively copy a directory's contents, continuing previously interrupted transfers, to/from a remote server via SSH/SCP, use rsync like this:

where either <source> or <destination> can be a local path (eg. /directory/with/files/) or a remote path (eg. youruser@example.com:/new/directory/).

"A long time ago in a galaxy far, far away ..." there was a touchpad that would register touches/clicks even while the user was typing. Ubuntu has a setting to compensate for this: "System Settings / Mouse & Touchpad / Disable while typing". Unfortunately it does not work (at least in Ubuntu 14.04 / Trusty).

The problem is with the "-t" option for syndaemon. It messes with syndaemon's functionality. The solution is to uncheck the "Disable while typing" checkbox in System Settings (Mouse & Touchpad) and add your own syndaemon command in Startup Applications (eg. /usr/bin/syndaemon -i 1.0 -K -R -d).

"FFmpeg is an extremely powerful and versatile command line tool for converting audio and video files. It is free and available for Windows, Mac and Linux machines. Whether you want to join two video files, extract the audio component from a video file, convert your video into an animated GIF, FFmpeg can do it all and even more."

Use the "atempo" filter:

I tried to find a solution for this question using ffmpeg, but had no luck. However the MP4Box method works like a charm.

Many video recorders (eg. GoPro cameras and many phones) split video files into 2 (or 4) GB pieces. To concatenate these pieces into a single file (without reencoding them), you can use ffmpeg's "concatenate" demuxer:

Server Name Indication (SNI) means that a compatible TLS client can send a hostname (aka. "server_name" field) in it's Client Hello message to the server indicating what virtualhost it wants to connect to and a compatible server can pick the right TLS certificate from it's configuration. This extension to the TLS standard aims to solve the SSL/TLS vs. single-IP virtualhosts problem.
