autojump: Linux cd command on steroids

autojump is “a cd command that learns,” one that programatically learns your favorite directories and allows you to minimize keyboard input to get you where you want.

autojump is a faster way to navigate your filesystem. It works by maintaining a database of the directories you use the most from the command line. The jumpstat command shows you the current contents of the database. You need to work a little bit before the database becomes usable. Autojump will listen and rank your ‘cd’ commands by frequency.

This seems like a good utility for commandline purists!

First step in using WordPress 2.6

Every other sites has reported on the release of WordPress 2.6, just like I did in my other blog. However, there’s something we are all overlooking — what are we supposed to do once we install/upgrade to 2.6?

Well here’s my first step: go to Settings → Writing and under the Remote Publishing options, make sure you uncheck the two fields named Atom Publishing Protocol and XML-RPC (you can’t miss them, there’s only two of them) if you don’t use them at all. If you have no clue what they’re there for, chances are you don’t need or use them at all and you can safely keep them disabled. This step is a must to reduce any possible security holes in your site as they have been a favorite target for hackers since the early days of WordPress.

Regular Expressions for Beginners

I must admit that as a PHP programmer for several years now, I can get away with most PHP functions and libraries, but I’m rather weak with regular expressions. I’d rather code it in some other way not utilizing ereg() or preg_match(). But don’t fret, I tried brushing up on them and these links might be just as useful to you:

Free PHP Books

Almost every web 2.0 developer has dabbled with PHP at least once in their lives, and though some praise Ruby on Rails or other framework, some live and die with PHP programming. I’m one of those PHP die–hards that would use it over anything else, as long as it is still possible.

Now if you’re one aspiring web developer or designer, or one of those special cross–breeds that excel in both, you’d love this site that lists countless free PHP books. Yes, free! Also listed on the same site are resources for other programming/computing topics that can be very useful for everyone. This one goes into my bookmarks.

WordPress Monkey

WordPress is really the “in thing” nowadays that even old school favorite webmonkey has a site building article using the popular blogging software. Theme installation and customization is pretty much covered along with a brief intro on WordPress plugins, nifty little extensions that could make or break (literally!) your site.

This new article almost coincides with the recent release of WordPress 2.0.3 which addresses several bugs and important security concerns. If you’re running the WP2 codebase on your site, be sure to get this maintenance release.

WordPress’s query_posts() function

The growth of WordPress has been overwhelming, and now almost everyone is blogging using WP as their platform of choice, or writing on The upsurge in usage and interest has spawned the development of various themes and plugins, allowing for use of WP in an entirely different form.

The query_posts() function is one you’re very likely to encounter when heavily playing with the application’s themes and pages. This function is essential in your arsenal in customizing your WP install and making it behave just the way you want it to.
