I would gladly pay more than $20 a year to have full access to my 150+ gig library of music. Until then, I guess I’m not allowed to play

I was working on one of my PHP based projects, and I was getting the following error:

Non-abstract method Foo::bar() must contain body in Foo.php on line 10

The problem was that I had accidentally put a semicolon at the end of the first line of the function:

WRONG WAY:

class Foo 
{ 
    function bar(); // extra semicolon! 
    { 
        // stuff 
    } 
}

RIGHT WAY:

class Foo 
{ 
    function bar()    // no semicolon, yay 
    { 
        // stuff 
    } 
}

Am I ordering the new iPhone 4S? As my tattoo says, “oh hellz yeah!”

I’m excited about the iPhone 4S and I’m going to pre-order it. I’ve heard a lot of people complain about the 4s, about how “It’s nothing new”, and “It’s basically the same as the iPhone 4″.

Here are the things that make the iPhone 4S different from the iPhone 4

• 2x the data speed
• 2x the CPU (A5 processor)
• 7x the graphics speed
• 8mp camera
• 5 element lens
• Larger camera CMOS
• 1080p HD video with image stabilization
• Longer batter life
• Bluetooth 4.0
• Supports GSM & CDMA (Use it on ANY carrier)
• Siri voice control
• Improved antennas

So yeah I guess besides those things, the iPhone 4s is just like the iPhone 4…

I love my iPhone, ive loved them all. I’ve owned every generation produced. With each release, the iPhone gets better, and becomes a larger part of my life. I use my phone a lot. It’s a mobile computer thats always with me. As an app developer, I can basically do anything I want with it.

When I ask people who are disapointed in the 4s, what they were hoping to see, the most common responce I get it, “I wanted it to be shaped different.” Shaped different! What? OK, I agree it would be cool to have a different sized iPhone, or a slightly different shape, but if I had to choose between better speed and an updated look, I’m going to pick the improved speed 10 times out of 10… I actally USE my phone.

I think more people would have been excited about the iPhone 4s if it looked noticabley different from an iPhone 4. I really think that most people care more about the status of the iPhone and the look of it rather then the utility and freedom it provides. If the iPhone 4S had a different style back, like metal instead of glass, I feel that more people would be impressed with it. There is nothing stylish about owning an iPhone 4S. The 4S update is about the “S”, speed.

Personally, I like to think that the 4S means “For Steve Jobs”. The world has lost a great visionary. Without him we wouldnt be arguing about iPhones. RIP.

If you have ever worked in a mulch-tiered web environment, you know how funny and true this is.

Mac OS X Lion (10.7), introduced a bunch of new features to the Mac platform. At the same time it’s taken away some things that experienced Mac users are used to. The idea was to remove things that the average user doesn’t need.

If your like me, you might have yelled “Hey! Where is the Library folder in OS X Lion?”, when trying to access data from the iPhone simulator.

After doing some research, I found that the folder was not gone, it had simply been hidden. Running the following command from the terminal, I was able to make my Library folder visible once again.

chflags nohidden ~/Library/

You may also need to restart finder by using this command

killall Finder && open /System/Library/CoreServices/Finder.app

If for some strange reason you want to go back to being a n00b and hide the Library folder again, you can use the following command

chflags hidden ~/Library

Just like my last post, I was working with a directory of about 1000 files. There was all sorts of problems with the way they were named. Anyone whos used a *nix type system will know that “.jpg”, “.Jpg”, “.JPG” are all very separate things. To solve the issue I was having I needed to rename all of the files in the directory to lowercase.

I fired up my friend the Mac terminal and ran the following command:

for i in *; do mv "$i" "$(echo $i|tr A-Z a-z)"; done

The code loops through each of the files in the current directory and renames it to the lowercase equivalent. fast, simple, elegant. Major time saver.

Recently I was presented with a problem where I had a directory of about 1000 graphic files of mixed formats (png, gif, bmp, jpg), and I needed to convert them all to jpg files.

I tried various solutions but I ended using the following command in my Mac’s terminal.

mkdir jpegs; sips -s format jpeg *.* --out jpgs

This command creates directory called “jpgs”, and converts all of the files in the current directory into .jpg format, and moves them into the newly created “jpgs” direcotry.

It truly saved the day.

That’s right, I’m speaking at the 2011 Orange County WordCamp, May 14th.

What is a WordCamp? WordCamp is a conference that focuses on everything WordPress. WordCamps are informal, community-organized events that are put together by WordPress users. Everyone from casual users to core developers participate, share ideas, and get to know each other.

I’m going to be presenting the topic, “Optimizing WordPress: Speed Matters”

By itself, WordPress is fast and snappy application but over time your site may become sluggish and laggy. A slow site is not good for your readers, or your search engine rankings. In a one hour presentation, I’m going to show some practical ways to optimize your WordPress sites content and configuration. The presentation will cover best practices, helpful plugins and real life optimization examples.

I’m excited to check out the other topics that are being presented. The OC WordCamp has three distinct tracks of sessions, beginners, advanced, and business minded users.

If you’re free on May 14th 2011 and love WordPress, you should come and hang out with some fellow WordPress users. http://2011.oc.wordcamp.org

Years ago I had the pleasure of meeting Ben Forta and listen to his thoughts on web development. One thing that stuck with me was his statement that:

“Dynamic programming languages like PHP and Coldfusion are great, but developers need to leverage the database more. Allow the database to do it’s job, the heavy lifting”

With that being said, I was recently working with a database that contained users first names. The data was not snantized at entry, and contained a mix of lower cased (ex. josh) and upper cased (ex. Josh) first characters in the firstname column. I needed to always present the users first name in a capitalized format.

The first solution that most developers would reach for is dynamically parsing the users first name, then upper-casing the first character. This works, but in my opinion isn’t the most elegant solution.

With a simple SQL statement, like the one below, we can return the users first name already in a capitalized state.

SELECT (UPPER(LEFT(firstname,1))+SUBSTRING(firstname,2,LEN(firstname))) AS firstname 
FROM users

Most of the time I only work with UTF-8 or UTF-16 character encodings. With that said, recently I was working on an old coldfusion project. Do to database restrictions, required all inputs from the user into the application to be Latin-1 (ISO-8859-1) character encoded.

Coldfusion does not have a good way of checking the character encoding of a string, so I had to pull out some of my Java skillz.

Dropping into Java from ColdFusion is a lot easier then it sounds. Check it out

<cfscript>   
   //use this to test character encoding. We only want Latin-1
    encoder = createObject("java", "java.nio.charset.Charset").forName("ISO-8859-1").newEncoder();
 
    if(encoder.canEncode(testVar))
    {
        //its Latin-1
    }
    else
    {
        /NOT Latin-1
    }
</cfscript>

The Java layer of Coldfusion is very powerful and under utilized by many developers.
