If you want your WordPress category slugs to look like http://www.dpnotes.com/nikon/nikon-50mm-f18d/ instead of the default http://www.dpnotes.com/category/nikon/nikon-50mm-f18d/, all you need to do is to install the WP No Category Base - WPML compatible WordPress plugin to strip /category/ from the URLs.

Note: You may have seen instructions on doing this that require you to hack and edit your way around the .htaccess file. Please do not follow those. Use this plugin method instead.

Here's what default category URLs look like in WordPress – this tutorial is all about removing the Category base:

Step 1.

In your WordPress admin control panel, navigate to Plugins > Add New. We want to search for WordPress plugins with the keyword "no category" in them. Enter no category for Term and click Search Plugins.

Step 2.

Click on the Install Now link under the WP No Category Base - WPML compatible plugin to install it. At the time of writing, the plugin version is 1.0.0.

Step 3.

When prompted Are you sure you want to install this plugin?, click OK.

Step 4.

You'll see some messages as the plugin is installed. Once the installation is completed, click on the Activate Plugin link to have the plugin start doing what it's supposed to do.

Step 5.

Verify that your Category web pages now have no /category/ in their URLs.

For the longest time, I had difficulties trying to grasp what the big deal about object-oriented programming was.

Coming from a comfortable familiarity with procedural programs, I couldn't see the benefit of developing systems using classes and objects.

I've just come across an article that explains in clear and simple terms, what OOP is all about, and I've finally seen the light after reading it – Understanding Java's Object-Oriented Programming (OOP).

A pretty elaborate hoax, if it's one (YouTube link).

Comments from Saurik, creator of Cydia, in this Hacker News thread:

Remember: Apple has costs in terms of payment processing, handles all of your complex accounting burden, takes care of district-specific sales taxes, manages currency normalization for worldwide distribution, and deals with any and all payment-related support requests (in numerous languages): they are left with a fraction of "their 30% cut", which is quite clear from their public financial reports.

Saurik emphasizes again:

… the things that Apple does which, for example, PayPal does not:

"handles all of your complex accounting burden, takes care of district-specific sales taxes, manages currency normalization for worldwide distribution, and deals with any and all payment-related support requests (in numerous languages)"

The App Store is a retail store: you hand them product and give them a general price point, and they handle the rest. All you need to do is develop your product and (hopefully) handle support directly related to the product itself. Otherwise, your abstraction is you are just sent a check every month.

If you choose to sell a product yourself, I hope you have a good grounding in sales tax law. For an example, did you realize that you cannot legally sell digital products to the EU, no matter what country you are a resident of, without registering for and collecting VAT?

You also will be dealing with a drastically different kind of support request, as there will be people claiming that you stole money from their credit card, that they didn't intend to make purchases, that they thought the price was different, that they made a payment to you with one credit card but now wish they had used a different one… some of these people are lying, some of them had their credit card number stolen, some of them don't realize that a member of their family uses their PayPal account to make purchases online, and all of them are much angrier than your normal support request. You can build systems that make these issues come up less often, but honestly then you end up spending much more of your time on payment processing than your application, so you should just pay someone else to take care of it for you.
