I just want to know if we are growing and being more relevant or not. I use FPC/Lazarus to write a program trading software to trade futures/options. I chose it because I need it to run on windows and (maybe in future) Linux and Mac OS. Could not use Java,C# because garbage collection and JIT compiler might cause the program to freeze in the middle of critical trading, which is utterly unacceptable for trading. FPC is also clean and easy to maintain and can actually do anything. I might lack some new syntax to speed up parallel programming or functional programming but those could still be achieved with a bit work. I don't want to invest in a new language just for a few new features but risk making some programming errors since I don't fully understand the language. Also, new languages come and gone so fast. I remember Flash's language was hot some years ago but now discarded. Also FPC's compile time is short compared to many other languages.

In fact, this is a good strategy. But makes me thinking if is difficult to find C programmers as well. The C language is old as Pascal. Why people continues learning C but not Pascal?

My experience with a multi-user project (Simba) that targeted Windows/Linux was very poor. It was hard to keep the project in a state that made it buildable on both OSes or even multiple. Eventually these issues were overcome, but there still seems to be a lot of hidden complexity that makes it hard to create reproducible builds and help new developers set up an evironment.
