The Regex method uses comma, full stop, hyphen, and apostrophe as word separators. The problem with this is that these characters are not universally used as separators. The hyphen is used to join two words. Could I suggest the following?string input = "Mr O'Brien-Smith arrived at 8.30 and...

For reference types, the hash is based on an internal counter that is incremented every time a descendant of System.Object is created. This happens in System.Object's constructor.For value types (structs), the hash is based on the first field. So if the first field is immutable, then you don't...

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?

Software Developer (Senior)
Belgium Belgium
I am an engineer with a background in electronics, software and mathematics.

I develop technical software, both for embedded systems and for desktop equipment. This includes operating systems, communication software, local networks, image processing, machine control, automation, etc.

I have been using all kinds of microcontrollers and microprocessors (Intel 4004/8080/8051/80386/Pentium, Motorola 680x/680x0/ColdFire/PowerPC, Microchip PIC, Altera NIOS, and many more), lots of programming languages (all relevant assemblers, Fortran, Basic, C, Java, C#, and many more), and different operating systems (both proprietary and commercial).

For desktop applications and general development tools I have been using both UNIX systems and Mac/MacOS for many years, but I have switched to x86-based PCs with Windows, Visual Studio and the .NET Framework several years ago.

I specialize in:
- cross-platform development (making software that runs on diverse hardware/OS combinations)
- instruction set simulation
- improving software performance, i.e. making sure the software runs the job at hand in as short a time as possible on the given hardware. This entails algorithm selection, implementation design, accurate measurements, code optimisation, and sometimes implementing virtual machines, applying SIMD technology (such as MMX/SSE), and more.
Technical Lead Air Liquide Industrial Services (Singapore)

My passion lies in building business intelligence and data-based solutions, writing about things I work with and talking about it. New technologies relevant to my line of work interest me and I am often seen playing with early releases of such technologies.

My current role involves architecting and building a variety of data solutions, providing database maintenance and administration support, building the organization’s data practice, and training and mentoring peers.

My aspiration over the next several years is to achieve higher competency and recognition in the field of Data Analytics and move into a career of data science.

Software Architect, COM, .NET and Smartcard based security specialist.

I've been working in the software industry since I graduated in Electrical and Electronics Engineering. I chose software because I preferred digital to analog.

I started to program with 6802 machine code and evolved to the current .NET technologies... that was a long way.

For more than 20 years I have always worked in technical positions as I simply like to get my hands dirty and crack my brain when things don't go right!

After 12 years in the smart card industry I can claim a strong knowledge in security solutions based on those really small computers!
I've been back into business to design the licensing system for the enterprise solution for Consistel using a .NET smart card (yes they can run .NET CLR!)

I'm currently designing a micro-payment solution using the NXP DESFire EV1 with the ACSO6 SAM of ACS. I can then add a full proficient expertise on those systems and NFC payments.
This technology being under strict NDA by NXP I cannot publish any related article about it, however I can provide professional consulting for it.

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.
