For PHP there are at least the following implementations related to Dependency Injection:

• PHP-Dependency (Pd) - A PHP Dependency Injection Framework
• Pimple – A simple Dependency InjectionContainer for PHP 5.3
• Zend Framework 2 Dependency Injection

PHP-Dependency (Pd) works with @ annotation in the constructor comment, but why involve the constructor? And is a whole framework needed? PHP is not Java.

Pimple is very much a Dependency Injection Container, not so much about the injection. Simple, yes.

When it comes to Zend Framework 2 Dependency Injection I just can’t grasp how it simplifies anything. It seems to require a lot of boilerplate.

Unsatisfied with the above and a given a dose of NIH Syndrome, I decided to create my own DI system for PHP. After a bit of coding yesterday evening and night I named it Pebble and it is already on github! :-)

My current requirements on Pebble are as follows:

1. It must be possible to inject values of specific properties on class construction
2. It must work nicely in Zend Framework 1.x
3. It must not require any configuration files (and especially no XML)
4. It must be a single .php file for the core implementation
5. It must provide an open interface for extension and customization
6. It must work nicely with PHPUnit (especially with the getMock method)
7. It must work with autoloading of classes in PHP
8. It is allowed to use PHP 5.3 features
9. It is allowed to use @-based annotations in docComment, e.g. /** @something */

However, I have not yet used Pebble with PHPUnit, so I don’t know yet if that requirement holds!

Now is a good time for you to examine example1.php! The README is currently plain-text, I’ll format it later!

This is quite OK, as my home-made web diary software – even rewritten in Zend Framework – will never have the same features as Facebook. There are no comments, photo uploads, likes, mentions of friends, etc, that the existing social networks already implement.

Of course I also have a Twitter account, @davideriksson, that complements this blog with mostly English-language updates regarding software development and related topics. I actually use Google Buzz for sharing some stuff with friends, and it is also connected to my Twitter account.

I never use my Orkut account so let’s ignore that. Should I mention my LinkedIn account? By its nature it is almost purely for my professional relations.

Now comes Google+ and I will give it a try as soon as they accept the invitation I have. Should I spend/waste my time on yet another social network, connected to more or less the same people?

What I want is to publish stuff (blog posts, links, photos, videos, status updates) in one place, and have it reach the desired target group (or Social Cicle, in Google+ speak). Something like Diaspora sounds like a good idea, but it is not click-and-play and does it integrate with the other social networks mentioned previously? I’m not so sure.

Ideally I publish something on Facebook and it ends up in the corresponding social circles in Google+, and the other way around.

Another solution would to be that I publish everything from my personal site, and it pushes it to the corresponding systems. Maybe I have to implement photo upload after all? And build an Android client? No, I should not have to.

A better solution would be that a single social network is my “main” one and it provides an API that I can use to share data to other social networks. Maybe Google+ is that social network, but it does not have a public API yet. I still have to build stuff, but integrating systems is much more fun than implementing photo upload… :-)

To see what others publish I realize that I still need to connect to each social network, but I’m probably curious enough!

The other day I was browsing already read articles in Google Reader, and found the article in Google Reader!

As I like the article very much and still would like to recommend it to others, I have decided to host it myself: The Book Of JOSH. Enjoy!

As painful as it is, we have deemed it necessary to cancel this years conference.

the meeting point for Agile Software Development in Scandinavia

I expect great talks and workshops. For example, Johanna Rothman will be speaking!

By the way, Lean Magazine #5 is available for download!

It’s actually just a page showing a screen shot and the name of the file that is currently playing, together with some commands to remote control XBMC.

Available commands are pause/resume, stop, play another file, and shutdown.

I also implemented support for showing notifications on the XBMC screen, which gave me an idea:

The Google Calendar can e-mail reminders for appointments. If XBMC is running, the reminder could be shown as a notification on the XBMC monitor.

I was just about to start implementing this calendar-reminder-in-XBMC when I reminded myself that there are many other small and big projects that would be more valuable for me. But instead of throwing this idea right down the trashcan I decided to blog about it first. Done!

Now I’ll spend some valuable time with my son!

• I’m not productive enough in C++ and I feel too limited by Java
• A large chunk of Java frameworks seem to serve no other purpose than to workaround limitations in Java
• I believe (and hope!) that Java will cease to be the default language in the non-Microsoft world, and that other JVM-based languages such as Scala, Groovy and JRuby will become more important
• How can I convince a client to allow Scala, Groovy or JRuby in a project?
• I should really get some C# experience!
• It seems like I almost always resolve to PHP when I need to get something done quickly… which reminds me of an upcoming blog post about a recent fight with SoapServer and SimpleXML to implement WSSE UsernameToken authentication.

Most date formatting comes from the DATE FORMATS section in include/config.php but even after changing these date formats I still don’t get all dates displayed as I would like.

For example, the text box for the date when editing an item is using the TZN_DATE_FRM constant defined in include/classes/tzn_generic.php. There’s a pretty naïve comment in the source code, saying that there is a “US format” for dates and a “rest of the world” format. Fortunately (for the US), the rest of the world is not united in opposition.

To get the date format I wanted I changed the constant definition like this:

define("TZN_DATE_FRM","%Y-%m-%d");

What I liked most about the job ad was the last part:

We’re hiring you for your mind. Please showcase it by answering some of the following questions in your cover letter:

• What is a recent programming insight you discovered and what was intriguing about it?
• Why do you want to work with us? (be specific!)
• What Open Source communities/projects are you a part of and why do you like them?
• Tell us about a time you brought initiative to your team and made a positive change.
• What modern programmer do you admire and why?
• How do you learn and keep up with the field of computing?

These questions really appeal to me!
