Switching coffee and PHP testing

Whoa, long time since my last post.

Anyways, what has happened recently?

I’ve switched jobs and are now working at a small IR firm in Denmark, which is located on Amager.
We do webcasts / Quarterly reports for firms in Denmark.

Saying “We do” is a bit off though.
I don’t, that is. I help out if we are missing a technician, else i’m creating webapps to help the business complete daily tasks faster.

And how is that going?
Well, I’ve completed a few systems already, and within one month the first system was deployed to the wild. It was fun to create a whole new system, especially because I am on my own.
Roughly speaking, i’m the only developer there, so I don’t get a lot of sparing on the code i’m writing. Only the designs and the general “look and feel” of an app.
It’s fun, it’s different and I like the pace.

An other thing i’ve been working on, is moving the old and new sites to new virtualized servers.
I’ve been managing a few servers for the last 6 years, but not anything on this scale. But it’s fun. It takes a little time from the programming though, but after it’s configured, it mostly runs smoothly.

I developed an SSO system and deployed it to the wild a few months ago. So far i’ve only had minor problems with it, and all things are running great.

And yes, I code in PHP. It was by choice actually. On my last jobs I’ve coded Bash, Perl, C, C++, then Java and then Ruby on Rails and on the new job I was given a free choice.

So I chose PHP.

“Why?” you might ask, when there’s soo much hype about Ruby on Rails these past few years. Without starting a flame wall in the comments, let’s just say, that while Ruby is a beautiful language, I just couldn’t get accustomed to the Rails frame work. So many rules, so many conventions. So little time. (The testing was nice though.. but meh)
I might return to Rails someday, but for now, it’s PHP controlling the battle.

The webapps i’ve created at my new job are all created using my small github project called php-mvc-base, which basically is just a structure I use to get started on a PHP project. It gives me “nice urls”, but other than that, the rules are pretty basic.

The structure outlines as follows:


And all controllers (ofc) go in the app/controllers folder.
So let’s say, that we want a new controller at the URL http://localhost/my_projects/ there is basically two things that can be done:
* Create a folder in the app/controllers folder, called my_projects. Place an index.php file there, do the controller code.
* Create a my_projects.php file in the app/controllers folder. Do the controller code.
Both options give the same path.

Simple and clean (well, at least in my world. And I use the folder approach btw, if you wanted to know).

(You can find the project at http://github.com/jimmiw/php-mvc-base along with a simple example.)

I’ve also released a few javascripts to CodeCanyon and I’ve had a few purchases already. It’s nice knowing people can use your stuff. I mostly coded them because I had a problem they could solve, but releasing them there, made the code so much better. This was mostly due to the javascript approval team on CodeCanyon (Thanks Jeremy McPeak for the patience and help).

You can see my profile on CodeCanyon here: http://codecanyon.net/user/jimmiw

I’ve also taken over a small project with a designer friend of mine called Janus C.
The project is familielivet and is a danish page the centers around the family. It’s free to use and hopefully easy to understand and use for all ages.
I’ve not actually released any code to the system yet, but we a doing some design changes and a total rewrite of the codebase, and it will hopefully be released soon.

After switching from Ruby to PHP I missed the easy testing that Ruby offered. Thank god for phpunit btw, this lovely tool simply makes testing fun again. Be sure to check it out when you are writing tests for your webapps (As you should be!).

On an interesting side note, Rails offers the ease of different environments for you to use.
E.g. Test, Staging and Production.
I actually found a simple way of doing this with PHP as well, but it requires that you have access to the apache configuration files (which you at least have on your development machine).

Roughly speaking, all you need to do, is to add a variable to your apache config, and then use the $_SERVER variable in PHP to test what environment your are currently working on.
Nice and simple.
A small example is this (taken from my development machine):
Just add the following piece of code to the bottom of your httpd.conf file
SetEnv APPLICATION_ENV "development"

And in PHP you can do the following when initializing the database connection:

  // development machine
  if($_SERVER['APPLICATION_ENV'] == "development") {
    mysql_connect(HOST, USER, PASSWORD);
  // add as many environments as you want
  // the ELSE part is used for production. On shared hosts you cannot edit the
  // httpd.conf file, so if nothing is set, assume it's Production ;)
  else {

I have a “unit” environment as well, which I use when testing database models using phpunit tests. This makes it easier to wipe database tables when starting tests.

And I switched from black coffee to Lattes.
No idea why, but after drinking black coffee for about 10years, they suddenly seem a bit boring…

Cycle through history in linux/mac terminal

If you are like me, you often use the terminal for… well.. let’s face it, most things.
I cannot remember one day, when i’m not bashing the keys in the terminal, trying to find, script or copy my way out of things.

Often I need to do the same things more than once. This could be connecting to a server to configure something, run a script I made earlier to resize some images, some FFMPEG command that I used earlier…

Eventually you get tired from hitting the arrow up key, and some years ago I got introduced to the “reverse history search”.
This is a way to search through your recent history (history being commands you’ve used in the terminal).

Simply hit CTRL+R to start the search, and the terminal will now look like this:

When you start typing, it searches through the history of your terminal.

One thing that bothered me though, was that I could only get the most recent result, and arrow up/arrow down doesn’t search through the results.

Hitting CTRL+R again displays the next result, that has the same command.

Just wanted to share it, happy bash’ing
