WordPress: How to Auto Expand Comments by Default

Clashing TinyMCE Editor Background

Easy to fix so this will be a short post except for text added for search engines…

Sometimes your content management system’s (CMS) theme and your TinyMCE editor’s editor field’s theme will clash their styles. For example, when your theme has a dark background color your TinyMCE editor will show a dark background in its text editor area which, if you use a dark text color, will make it difficult for you to discern your text from the editor’s background color (i.e black on black is black just as white on white is white).

The reason for this clash is that TinyMCE derives its styling informtion (the style.css details) from your theme’s style details; namely, the theme’s body tag’s styling data. To fix this, whether your using Wordpress, Joomla!, Mambo or any other CMS, all you need to do is add a short line of code to your theme’s css file.

How to Make a Semi-Transparent Image Using GIMP

Two things I recently learned to do with GIMP:

1. convert every occurrence of a particular colour into a transparent region (good for web graphics), and
2. make an image semi transparent so that it may be used as a watermark.

Here’s how to do those tasks.

Hardware Discovery and Fault Diagnostics

A Couple of neat tricks I learned while trying to establish a wi-fi Internet connection through the command line are the command line instructions for discovering a computer’s hardware and the device drivers that make them work. Those commands are:




The first three of those commands are available on most, if not all, Linux environments. lsdev must be installed using sudo apt-get install procinfo .

You should run them as the root user either by adding sudo before the command else by typing sudo su (followed by pressing the return) key as your first instruction. If you use sudo su then remember to type exit after you’ve finished issuing commands.
