Re: PROGRAMMERS: WIND RIVER C++ vs LABVIEW vs JAVA

NI does many things well but can it be that their compiler tech is way ahead of companies and open source contributors whose sole focus is compilers? Maybe so...

Why would one language be better in a multi-tasking environment than another? The VxWorks kernel and its native API are in C. Some languages (like Ada) have multi-tasking elements built into the language. I can see how they are more convenient. But you can't hide or abstract things w/o it being slower and/or less capable. Even the compiled versions of LabView must access the VxWorks API and the system call interface to interact with the OS. In any language some simple calls setup the tasks. The kernel does the multi-tasking for you w/o any further work by the application code (given a good design).

I love to use LabView for many kinds of tasks. But I would NEVER hire a software engineer to do embedded work that cannot use C/C++ effectively. Many times it is all that is available.
