When a site gets a lot of repeat traffic we can dramatically reduce the load and costs by caching.

Skype API Basics – Part 1
What is the Skype API?
The Skype API is an easy way to create plugins that can dramatically change the way Skype functions. For example, we could make a program that reads messages out loud as we receive them instead of having to check for new messages.
The Skype API is potentially very different for each of the operating systems Skype is available for. And, of course, there are different wrappers of the API available for some of the different languages.
What Operating Systems Are Supported?
- Linux
- MAC
- Windows
What Languages Are Supported?
The Windows API,Skype4COM, is supported in literally any language that can import an ActiveX DLL or using a bit of hackery and some Skype commands we can also use Windows Messages via the Win32 SendMessage API .
Wrappers are available for additional languages that aren’t necessarily updated as frequently as Skype4COM. Skype4Java is a completely cross platform, language specific, implementation of the Skype API. Unfortunately, Skype4Java is infrequently updated and often lags behind the other implementations. Skype4Py is the other language specific implementation of the Skype API and can be used with Python on Windows and Linux.
What is Skype4COM?
Skype4COM is an ActiveX dll for use on Windows. Basically, it offers us a collection of properties, objects, and interfaces that we can use to manipulate Skype. By default, Skype4COM is installed with the Skype Extras although I always think it is prudent to provide it with our application and reference the included version.
What is Skype4Java?
Skype4Java is an older language specific wrapper for use with Java and is pretty much outdated and dying. I haven’t personally used Skype4Java, but have noticed it hasn’t been updated since 2006.
What is Skype4Py?
Skype4Py as previously mentioned is the language specific wrapper for Python and is fully supported on Linux and Windows. Skype4Py contains two different naming schemes: one follows the norms of Python, and the other set of naming conventions resembles Skype4COM.
Why use the Skype API?
There are a lot of interesting applications that make use of Skype to do telemarketing (predictive dialing even!), make Skype act like a fax machine, and even completely replace the need for a telephone! Unfortunately, my first use of the Skype API was to monitor employees that were deleting their Skype history and copy all of the messages sent and received to a location.
How should I get started?
Usually, I start reading a little bit about the API before, I begin to use it but I don’t ever focus in enough to learn the API completely unless I absolutely need to. Instead of spending your time focusing on learning APIs you should instead focus on learning computer programming fundamentals or some website development fundamentals.
More coming next week!
Open Source Week 2009
I am so excited to say that I finally booked everything I need to attend the Toronto Open Source Week. In a couple of weeks time, I will be spending a couple of days in Toronto while attending the many conferences, workshops and presentations on open source software (GNU Linux, PHP, etc.)
I am hoping to do some serious networking for my consulting business, along with getting more experience with web programming and the rest of the LAMP stack which seem to be creating an IT revolution.
I hope to see you at some of the events!
How do I check if Ubuntu is 32 bit?
1. Open up the terminal
2. Type uname -m
Thoughts on Linux
Almost a year later, and I don’t think I would ever consider going back to any of the Microsoft Windows Operating Systems.
Becoming a Super User In Ubuntu
In Ubuntu, by default, the root user’s password is locked. This means that we don’t know it and we can’t always sign in as root or unfortunately use the normal linux su command either.
