WebLogic package-name element classpath generator script
I wrote a post a few days ago about using Jersey 2.x as a shared library with WebLogic 12.1.2. In that post I suggested the following: In weblogic.xml the prefer-application-packages element needs to have entries added for ALL OF THE PACKAGES in the Jersey 2.x shared library JAR files. That means you need to go through every jar file in WEB-INF/lib for the shared library that was created with Maven and make sure the packages it defines are included in this element.

Show transfer percentage and speed when copying files in Linux and Bash
As great as Linux/Bash is, sometimes I wish some of the built-in commands did a little bit more than the bare minimum.

There are many questions about this very thing on StackExchange like this one and this one. My preferred solution is to use 'rsync' but I'm also a big fan of simplifying things and can never remember all the various command line options required. So this post shows my little trick to enabling file copy speed and percentage display when copying files.

Prevent errors during ffmpeg execution in a loop
I was using my Odroid XU4 based media server to transcode some videos using ffmpeg when I came across some strange errors appearing on the console. When I would run ffmpeg as a single command, it would work, however running it in a loop presented errors (or rather strange behaviour).

Mouse wheel displaying control characters in a terminal or scrolling through history instead
I've recently had an odd experience when using Bash. When I used the mouse wheel to scroll up/down the Terminal window (in OSX) all I got was some control characters being printed out. It looked similar to this...

Visualising Oracle database partition data distribution with gnuplot
We use partitioning in at least one of the databases at work, changing to partitioned tables has allowed us to keep the system running within our imposed SLAs. Recently I've started to wonder however, what happens when we start hammering individual partitions more than others. The data distribution would be skewed and the benefits of partitioning lost. I decided to put together a bit of SQL and then use gnuplot to show me how well our data is distributed.
