Recently I upgraded to WordPress 2.8.5. The upgrade process itself went smoothly but some of the plugins I have installed on my blog stopped working with latest WordPress version. One of them is AdSense Deluxe.I use AdSense units on my blog (as you can see) and use AdSense Deluxe plugin to manage my ads. The plugin was still displaying my AdSense units properly, the problem was that I could not access its admin panel to change settings or ad units. I was getting following error.
“You do not have sufficient permissions to access this page.”

Nothing is more embarrassing than a misspelled word or incorrect grammar in an article on your blog. OK, may be there are other more embarrassing things out there but this still is not a nice scenario for a professional blogger. As a blogger you should try to catch all your mistakes before your readers catch them and point fingers at them (or worst publish your mistakes on flickr for all to see:) ). Almost all commercial word processing programs offer built-in spell and grammar checkers. These tools allow the users to write without worrying too much about the spelling and to some extent the structure of their sentences. This peace of mind naturally increases their productivity. Now you can get that same functionality for your WordPress blog by installing a smart plugin. Aptly named ‘After The Deadline’, this plugin frees you from worrying about spelling and grammatical structure and let you focus on your main goal – to write.
“After the Deadline is a plugin for WordPress and TinyMCE with contextual spell checking, advanced style checking and intelligent grammar checking.”

Recently Darren Rowes of problogger.net launched a premium forum for bloggers ( problogger.com). I was surprised that he offered the membership of only $1.95 a month.
I singed up as soon as I heard the news and I believe it’s worth much more than that. The community is getting close to 2000 member strong. The first advantage of a fee-based forum is that usually do not get spammers flooding the message boards. Continue Reading…

A couple of weeks ago a reader asked me for a Java program to read command-line input from the user and then display the smallest value the user has entered. He wanted to use digit ‘0′ to indicate that the user is done entering the data and not to include 0 in the list of numbers entered by the user. Here is the Java code to do this. Bonus: This program also determines the largest value entered by the user.
