Expertise

I am a software developer with more than 15 years C++ experience and over 25 years experience developing a wide variety of applications for Windows NT/2000/XP, UNIX, Linux and other platforms. I can help with basic to advanced C++, C (although I do not write just-C much if at all these days so maybe ask in the C section about purely C matters), software development and many platform specific and system development problems.

Experience in the area

My career started in the mid 1980s working as a batch process operator for the now defunct Inner London Education Authority, working on Prime mini computers. I then moved into the role of Programmer / Analyst, also on the Primes, then into technical support and finally into the micro computing section, using a variety of 16 and 8 bit machines. Following the demise of the ILEA I worked for a small company, now gone, called Hodos. I worked on a part task train simulator using C and the Intel DVI (Digital Video Interactive) - the hardware based predecessor to Indeo. Other projects included a CGI based train simulator (different goals to the first), and various other projects in C and Visual Basic (er, version 1 that is). When Hodos went into receivership I went freelance and finally managed to start working in C++. I initially had contracts working on train simulators (surprise) and multimedia - I worked on many of the Dorling Kindersley CD-ROM titles and wrote the screensaver games for the Wallace and Gromit Cracking Animator CD. My more recent contracts have been more traditionally IT based, working predominately in C++ on MS Windows NT, 2000. XP, Linux and UN*X. These projects have had wide ranging additional skill sets including system analysis and design, databases and SQL in various guises, C#, client server and remoting, cross porting applications between platforms and various client development processes. I have an interest in the development of the C++ core language and libraries and try to keep up with at least some of the papers on the ISO C++ Standard Committee site at http://www.open-std.org/jtc1/sc22/wg21/.

Education/Credentials

What do you still hope to achieve/learn in this field?

I hope to grow my (UK) company - Dibase Limited - and to produce software products of my own, rather than always working on the assignments of clients.

Something interesting about this subject that others may not know:

The ACCU is an organisation of programmers that care about professionalism in programming and raising the standard of programming. The ACCU is not just for experts and welcomes less experienced programmers. The ACCU website (http://www.accu.org/) has many useful book reviews and links.

Well if you are using the raw socket C API then I have to point out that it is very error prone and it is _very_ easy to make mistakes. Anything to do with networking is complex as there are so many points

I would like to start by stating the assumptions I have made from your question for the purposes of the answer:    1/ by 'vector' I am assuming you mean a single dimension array, specifically a C++ library

2011-12-12 dynamic bit-fields:

Short answer: no    You cannot modify types at runtime - all types and their structure have to be defined at compile time - C++ is a statically typed language. Bit fields are a low level feature best used

2011-12-06 scope:

Err, maybe because the function is an _instance_ _member_ of a _class_ and so needs to be called on an _instance_ of that _class_.    Maybe you just forgot that when fixing the mergeFiles definition you
