To remove these svn folders from your project, right click on the project > Build Path > Configure Inclusion / Exclusion Filters…

Click “Add…” next to the “Exclusion patterns:” box. Add the rule “**/.svn/”. The “**/” will make it a recursive rule. Click Finish and your annoying .svn folders should now be hidden in the file browser.

1. SSH to the samba server
2. Log in as root
3. smbpasswd -a username
4. Enter password (twice) – no characters will appear on the screen

Interesting note: if you aren’t logged in as root, the smbpasswd command line tool can be used to change you samba password.

Webkit will be the future rendering engine of the mobile web (at least I hope it is).  It’s an amazing, full featured engine with bleeding edge web standards implementations of HTML 5 and CSS 3.  Webkit has been getting some great traction lately with some amazing devices implementing it as their default browser engine, Android, Palm Pre and of course the iPhone (and iPod Touch) have all fully embraced Webkit.  I want to see that list get a lot longer; I hope to start seeing Webkit on lower end mobile devices.

What makes Webkit so awesome?  How about CSS effects, blazing fast javascript execution (especially in their new Nitro engine in Safari 4), HTML offline support – including offline data storage and support for offline cache manifests, CSS gradients, CSS border radius and border images, CSS transforms, and a lot more.  On the iPhone, it now even has custom events to pass down gesture events to the DOM.  You can now do most things you could once only dream of doing in flash in straight HTML, CSS and Javascript on small devices stored in someone’s pocket.

The future of mobile web applications are social, location aware, providing a tailored experience based on user preferences.  Future mobile web applications will morph based on user behavior.  The will provide a graphically rich experience with beautiful design elements enhancing every aspect of the application.

Here's the quick and dirty: I have a game that we're building here at Treemo Labs, Tic A Tac Poker. We're working on getting a lite version out the door. I wanted to read a custom value out of the Info.plist to tell if it's the lite version or not. I couldn't figure out how to read a simple value from the default property list file. Here's some sample code to get the bundleIdentifier, bundle version and custom values from your Info.plist

For more information about the NSBundle, view the NSBundle Reference Documentation.

During my senior year at Western Washington University, for a final project in my Management 495 class, I did group presentation, performing a strategic analysis of Google and the positioning in the search engine market. I posted this slideshow to slideshare and received an incredible amount of comments and messages asking for the presentation. The presentation currently has over 25,000 views and over 100 favorites.

Like I said in the disclaimer, this slideshow is a year and a half old so a lot of the information is out dated. Also, looking back at the slideshow, there are some formatting issues that I would resolve if I had to go back and do it again. The presentation, was put together using Apple's Keynote software. This was a group presentation so I was not the only contributer. The other contributers were: Charity Thomas, Frieder Mack and Jennifer Bell.

When deciding what the data structure should look like, I wrote some pseudo XML that we need to be able to model.

A Node has a (string) $type, (mixed) $attributes and (NodeCollection) $children. Using the above XML as a reference, our root node (let's call it $root) would have $type = 'channel' and no attributes. You would then add two nodes to the NodeCollection $children, owner and list. Owner would have $attributes of array('name'=>'testuser', 'email'=>'test@test.com') and $children would be an empty NodeCollection.

The biggest design decision made about NodeCollection was that NodeCollection implements Iterator. By implementing Iterator, you can later foreach over $children and it can loop through the elements with no problem. Implementing Iterator is a pretty cool design pattern - I'll have to write a post about it in the near future. The ability to foreach over $children helps tremendously when writing ExportNodeToXml.

Wrapping up, pseudo code to export and object to a Node that can later be transformed to XML would look like this:

Recently, I've rediscovered my love for public radio. With the trio of eclectic music from KEXP 90.9, dance and techno from C89.5 and local, national and international news from KUOW 94.9 I can always find something good to listen to. Not only am I aurally satisfied, listening to public radio often seems to put me in a civically minded mood - encouraging me to soaking up as much information and culture as my brain can handle.

On another note, I haven't posted in a while - after graduating, I started at a company called Ascentium. They are an interactive technical marketing and consulting firm. I worked there as a web developer for about 2.5 months and then I decided I wasn't really being challenged enough and I missed writing PHP a lot. So I left to start working at a startup that I had looked at during my initial job search right after graduating, Treemo.

I've been at Treemo since the middle of June and I'm loving it. We have some really cool stuff coming down the pipe in the near future. Right now, I'm working on writing an API - very exciting work. Now that I'm working back in the PHP biz, I'm going to start writing about developing PHP again. Stay tuned.

Let's look at a simple example. I have an array containing values, some are numeric, some might not be. I only want my array to contain the valid numeric entries and I want to delete the other values. PHP has a helper function we are going to be utilizing, is_numeric.

The output from above is:

Array
(
    [0] => 42
    [1] => 96
    [2] => 100.96
)

Pretty handy function. Notice how I ran my data through the function array_values, before that function was run, the keys were (0,2,4).

Another example with a user defined function. I have defined a collection of tags and I want my tag collection to only contain tags that match the criteria the user has requested.

Voila! Deleting elements from an array has never been easier.

For more information, see the php documentation on array_filter.

I put together a quick page that I can navigate to that will install a cookie for the browser. I can then check for the cookie in my standard header include so the Google Analytics tracking code isn't sent to the browser.

The code to set the cookie (and make sure it's installed correctly)

Similar (but inverse) code is then inserted in my header

Analytics is a great tool and it's going to be even more useful now that I won't be tracking my own hits.
