Annotating the photograph with comments.

There is a nice Linux command called convert. This command can be used in various ways to do image manipulation. One of them is to embark your image with some text. Here is how to do it.

**echo ”Annotating the image ”$2” with $1”
convert -font  Verdana -pointsize 40 -fill red -draw ”text 100,100 ”$1”” ”$2” ”$2”
**

It will be good idea to save this as ”annotate” as we will use this later too.

Couple of days back my TeraByte HDD crashed and I lost almost everything, including my homedir. I will tell you my experiences and how my measures helped me lose not much data. So I will begin with one of the most important aspects. My BROWSER.

I have all my passwords stored in the browser and I rely on them so it is not stored anywhere else. Also, I have lot of bookmarks which help me do lot of stuff. Meaning, all these are very important for me. So, I had a backup plan for my passwords and bookmarks.

How To Build A Self-hosted WordPress Blog For Free

A blog is a layman-friendly variation of a website, and having a blog is one of the many ways to state your presence in the virtual world. While there are many hassle-free blog services out there that will take care of everything except automatically blog for you – like <a href="http://www.makeuseof.com/tags/blogger">Blogger and <a href="http://www.makeuseof.com/tags/wordpress">WordPress, nothing can beat a self-hosted blog in the terms of customization and self pride.

The problem is, the process of building your own self-hosted blog is (almost always) not free and is considered complicated. So most newbies will choose the easier path and never give themselves a chance to experiment.

Splitting strings with IFS

Today I want to discuss splitting strings into tokens or “words”. I previously discussed how to do this with the <a href="http://bashcurescancer.com/reading-a-file-line-by-line.html">IFS variable and promised a more in depth discussion. Today, I will make the case on WHY to use IFS to split strings as opposed to using a subshell combined with <a class="zem_slink freebase/en/awk" title="AWK" rel="homepage" href="http://cm.bell-labs.com/cm/cs/awkbook/index.html">awk or cut.

I wrote this script which reads the /etc/password file line-by-line and prints the <a class="zem_slink freebase/en/user" title="User (computing)" rel="wikipedia" href="http://en.wikipedia.org/wiki/User_%28computing%29">username of any user which has a UID greater than 10 and has the shell of /sbin/nologin. Each test function performs this task 10 times to increase the length of the test:
