absolute positioning not working in firefox

position: absolute works in Firefox. Most likely the top and left attributes are not specified. An important point to note here is that firefox does not allow tags like top: 124 px; note the space between 124 and px. Or may be it is an issue with the padding of the parent element. Either way firebug is an excellent tool to debug css issues in firefox and chrome

Zend Form File Uploads – Unique Filenames

Wanna learn something new? Ensure u know the prerequisites.

As a first step of learning ZF I've developed a simple blog after I've finished the quick start guide. Unfortunately, I did not care much about the RewriteEngine. So, when I tried to include an external css file I got an error saying

Invalid controller specified (css)

Now I tried creating

css/global.css

in my document root (with out any content). Even that did not help. As a final resort I tried putting some text into css/global.css And viola!! That worked.
If u are new to ZF I recommend to get the basics of mod_rewrite

Logs are there for a purpose

If u ever encounter 500 Internal server error, 403 Forbidden, 404 not found errors the best place to check will be the log files. Moreover ensure you use RewriteLog every time You use RewriteEngine

A chain is only as strong as its weakest link

In the qualification round of GCJ '10 there was a problem involving integers ~10⁵⁰. I had to use gmp_* for that. Every thing worked fine for a small data set. But the program gave unexpected results for a large dataset. Then I realized that I've used mod in my code. Replacing that with gmp_mod did the job.
