The easiest singleton pattern is the one you used to the lock object itself.Creating any variable as static readonly and initializing it directly (or via a static constructor) will already make it singleton.Also, considering that "lock" clears all the caches, you don't need to declare the...

#realJSOP
Software Developer (Senior) Paddedwall Software
United States United States
I've been paid as a programmer since 1982 with experience in Pascal, and C++ (both self-taught), and began writing Windows programs in 1991 using Visual C++ and MFC. In the 2nd half of 2007, I started writing C# Windows Forms and ASP.Net applications, and have since done WPF, Silverlight, WCF, web services, and Windows services.

My weakest point is that my moments of clarity are too brief to hold a meaningful conversation that requires more than 30 seconds to complete. Thankfully, grunts of agreement are all that is required to conduct most discussions without committing to any particular belief system.

Object-oriented (OO) is about "classes" not "objects". But I truly believe that "objects" deserve more our attentions. If you agree, read more on... Dynamic Object Programming (DOP), Component-Based Object Extender (CBO Extender), AOP Container and Dynamic Decorator Pattern.

Mobile development is not just another type of front end. The real challenge is actually in the back end: How to present meaningful information in time to mobile users with exponentially increased data flooding around? Here is my first mobile solution: SmartBars - Barcode Reader, Price Comparison and Coupons.

Gary lives in southeast Michigan. My first programming language is FORTRAN. For the last a few years, I have primarily focused on .NET technologies with Mobile Development as my newest interest.

I am a software developer (mainly in C# and T-SQL) for a project management company in Athens, Greece. I have been working with computers since early 1987. I am adept at Pascal, C, C++, Java (my MSc was sponsored by Sun Microsystems), Lisp, Scheme, F#, C# VB.Net, Perl and some others that are too obscure to mention. When I want a quick and dirty solution to a programming problem I use a functional language, such as Haskell, Scheme or, more recently, F#.

I also play the keyboards and compose music.

Paulo Zemek
Software Developer (Senior) Microsoft
United States United States
I started to program computers when I was 11 years old, as a hobbyist, programming in AMOS Basic and Blitz Basic for Amiga.
At 12 I had my first try with assembler, but it was too difficult at the time. Then, in the same year, I learned C and, after learning C, I was finally able to learn assembler (for Motorola 680x0).
Not sure, but probably between 12 and 13, I started to learn C++. I always programmed "in an object oriented way", but using function pointers instead of virtual methods.

At 15 I started to learn Pascal at school and to use Delphi. At 16 I started my first internship (using Delphi). At 18 I started to work professionally using C++ and since then I've developed my programming skills as a professional developer in C++ and C#, generally creating libraries that help other developers do their work easier, faster and with less errors.

Web Developer
Greece Greece
I am a web developer for a software house in Athens, Greece. I currently work almost exclusively with the Microsoft stack of languages, and most prominently with C#. However, I have worked extensively with PHP in the past, dabbled in C and C++ while doing my MSc, and for my pet projects I usually resort to Python, if a GUI is not necessary. That said, I'm also usually the guy that oversees/designs the database schema for each new project at work.

When not in front of the computer, I enjoy watching and helping my two young daughters grow up. Sometimes I do that while in front of the computer too.
