In Ubuntu 14.04 the "Disable while typing" in touchpad settings does not work

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).

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

How to concatenate multiple segments of the same video into a single file

Sun, 2015.04.12 - 22:50 — müzso

https://trac.ffmpeg.org/wiki/Concatenate

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:

ls -1 G*0060.MP4 | sed -r "s/(.*)/file '\1'/g" > list.txt
ffmpeg -f concat -i list.txt -c copy GOPR0060.joined.MP4

TLS extension to support multiple certificates for virtualhosts

Wed, 2015.03.18 - 01:11 — müzso

https://en.wikipedia.org/wiki/Server_Name_Indication

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.

Validate XML documents via a bookmarklet

Fri, 2015.03.06 - 20:10 — müzso

I've attached a simple HTML file that contains a textarea and some JavaScript. You can paste any text into the textarea and pressing the button will invoke the browser's XML parser and test whether the text is a valid XML document.

I've also modified the JavaScript code so it can be used as a bookmarklet: Verify XML

Just drag&drop the link to your bookmarks bar, select some text on a page and click the bookmark(let) to validate it as an XML document.

This is a nice intro into using SL4A+Python with Tasker. And the actual task (silently take a photo of a possible thief) is useful as well.
