Cartel – Chroma

My most recent CD purchase was Cartel’s new release titled Chroma. Priced under $10, I am willing to buy the actual CD rather then the digital download off of iTunes. Their music is classified as Alternative, just what I like.

Chroma contains 12 songs. Of those 12 there are at least 7 great songs. Rather then describe the entire CD to you, I will glance over a few of the songs to give you an idea of what to look for.

Say Anything (Else) – The opening of the CD gave my a smile. I knew I would get decent music. One of the upbeat songs, they had a nice recurring theme and unique melody. Cartel seem to produce really catchy choruses, this is no exception.

Runaway – The third song on this CD is one of my favorites. One of the aspects I think Cartel does very well is their choruses are almost always phenomenal. In my opinion, the first verse and chorus make or break a song, followed by an excellent bridge somewhere in the song to bring some life back into it. Runaway does just that, the first 30 seconds show Cartel has the ability to create a compelling introduction. This song does not disappoint as it continues. The vocals, another aspect I regard highly, are very well done.

Save Us – Resisting the urge to listen to the next engaging song, I skipped to Save Us, song number 6. Showing a different side of the band, Cartel has a softer song. Less driven by guitar and drums, this song has a piano background and masterful vocals. Solid all the way through, this song is a nice break from the rock and it gives the CD some balance.

The Minstrel’s Prayer – The most unique song on the CD. The beat, harmony, and lyrics make this one of the most entertaining songs. Here is the second chorus, I wouldn’t dare ruin the chorus for you (but iTunes would…):

All these minstrels through the ages
That is really all we are
Simply singing for the girl
That makes us try so very hard
To craft the perfect limerick
To wield unending woe
To write such silly songs
And the difference never known.

I hope you take some time to listen to the clips for these songs. If you check out the iTunes previews for these songs I will gladly tell you that they are decent clips. I am glad that their preview of Save Us does not reveal the best vocal. I deliberately avoided their single, Honestly, which I had heard before I bought the CD. I don’t think that is anywhere near this CDs best songs.

Also, I reviewed four songs, two of which were the slower songs on the CD, which is rather unusual for a review of an alternative band. The top downloads are of the upbeat songs, and I would have to say those are the expected top downloads from this genre of music. Overall a great CD, worth the $10. As I mentioned, I listen to alternative for both the vocals and the fact that they keep their music interesting all throughout. Alternative shines in that category and this CD keeps me happy and entertained.

Advance Your Programming – Part 1 – Regex

In my case I will talk about PHP, because it is so widely available (nearly 100% of reasonable hosting companies include PHP support in even their lowest plans). This article is also geared toward rather novice programmers because surely the aspects I mention can be seen on the tool belt of all master programmers.

  • Regular Expressions

  • Templates and Includes

  • XML Parsing

I will only touch light on these subjects in the hope that you will continue research on them if you have a desire to improve your skills. Once learning each of these, your understanding of web programming will be greatly improved, your code may become cleaner and more concise, and most importantly you will have more fun programming! Today’s article will focus on Regular Expressions, commonly refered to as regex.

Regular Expressions – Regex

This will not be an article teaching regular expressions (I may refer to them as ‘regex’). I would rather this be a stimulus for you to learn regular expressions if you are currently in the dark, and afterwards I may provide you with a few sources to help you learn regular expressions. You don’t need to really understand the regex that I show you in this article, nor will I really explain them to you. You may even be able to decipher what the regex means on your own. Keep in mind that I am showing you uses of regular expressions, their powerful and simplicity, as a means to entice you to learn them yourself. You will not regret it.

Regular expressions are a language in their own. At first glance, a regex may appear complex, but they are in fact very straightforward and they have many uses for web programmers. Regex provide pattern matching for strings. A common use is searching a string for something, if that something exists then execute some code. Or the reverse, if the pattern is not found then execute some code. One such example is input validation.

Lets say you have a simple contact form, which asks for a user’s phone number and email address. Those are common form elements and should be checked for valid input so you can be sure users are not putting deliberately fake input or perhaps a simple typo in their phone number. Regex can ensure that the users input is not only valid, but that it is also in the correct format that you specify, making your work easier.

Lets make a simple PHP example, with hardcoded values, and the phone number format we want is ###-###-####.

$str = '555-555-555a';
$regex = '/^d{3}-d{3}-d{4}$/';
if (preg_match($regex, $str))
  echo 'This is a valid phone number.';
  echo 'Bad phone number.';

The regex is located between the forward slashes. / here /. I am also using a PHP function preg_match( regex, string the regex works on ). For those interested, here is the documentation on preg_match from Copy, Paste, Save, and Run this example and you should see that the result is that 555-555-555a is indeed a bad phone number! The reason, you probably determined, was that ‘a’ is not a number! The preg_match() function applies the regex on the string and finds that the string is not in the correct format (described above). Powerful, simple, and fast! To see the script in action with a working phone number change $str to any valid phone number, here is an example:

$str = ‘123-456-7890’;

With one simple string we force all input to be exactly how we want it! To show how flexible regex can be, we can extend the regular expression to allow for a phone number in either: ###-###-### format, ######### format, or (###) ###-#### format! All at the same time like so: /^(\d{3}-\d{3}-\d{4})|\d{10}|(\(\d{3}\) \d{3}-\d{4})$/

Now lets take a look at an email address. An email address to be valid should look something like: It may even be as complex as:, but lets just have a regex to allow for a simple email address. Here goes:

$email = '';
if (preg_match('/^[a-z0-9_-]+@([_a-z0-9-]+.)+(com|net)$/i', $email))
  echo 'Valid Email ending in .com or .net';
  echo 'Bad email address!';

The regular expression allows for only a simple email address. It only allows email address ending in .com or .net, but that can easily be extended. I think you can see how powerful this is! Only allow valid formatted email address will prevent problems down the line if you ever have to email this person using a script. At least the email will be correctly formatted, at least your script won’t crash prematurely due to a formatting error, but instead the worst that could happen was the email is sent but no one ever receives it!

The simplicity of regex in form validation is unparalleled. How would you ensure that the user put in a valid phone number?!? Would you individually check each character in the string? Make sure that the first character is a number, the second, the third, then a dash, number, number, … A pain to do manually, regular expressions are just a single string which can do all of the work.

Soon I will provide another use of regular expression, search and replace! There are countless uses but I will cover topics you will surely have to deal with as web programmers, and by learning regular expressions you will see a new world of possibilities. It would be best if you started to learn the basics of regular expressions and so I will provide you with some links.

Augustana – Boston

My first music post will be one that hopefully everyone would like. If you are not hooked after the first chorus of this song, then I failed. The piano is a nice addition to the solo voice, and it carries the song nicely, but its not song that would put you to sleep while driving. Although I prefer Alternative music, this song does have a great appeal to me. It reminds me of Danial Powter’s “Bad Day” which had the ability to appeal to all ages and music genres.

I will point out that I will not post downloads to songs, although occasionally I will provide a link to a preview of the song. I would just rather you get a preview of the song through iTunes or your favorite music program, to get a taste of the song.


My first WordPress blog. I admit that I am very pleased with everything that WordPress has, and the themes that are available online are fantastic. I really look forward to using this blog and experimenting with everything that WordPress has to offer.

As for this blog, I imagine three categories: family, web development, and music. That means that reason you are here is most likely for web development and I welcome you with my warmest smile. I would like to be of some help to those who are just learning or experimenting with web development, or intermediate programmers like myself, and I hope I can make it more fun and interesting.

I hope you learn something while you are here,
