Bruce Eckel???s recent blog post on the legacy left by C++ and Java generated a lot of reaction. While mentioning some design mistakes, he concludes that both languages have had a significant role in programming languages evolution and an important positive legacy. But is it not too early to talk about their legacy? Eckel, a former member of the C++ Standards Committee, recollects the decision made regarding backward compatibility of the language with C from the beginning:

In CUDA, Supercomputing for the Masses: Part 10 of this article series on CUDA (short for "Compute Unified Device Architecture"), I examined CUDPP, the "CUDA Data Parallel Primitives Library." In this installment, I revisit local and constant memory and introduce the concept of "texture memory."

A number of folks have asked me what tools and techniques I use to reverse engineer Cocoa executables. I thought it would be worth taking some time out from documenting undocumented APIs to show you how easy it is to do the same thing for yourself.

Bruce Eckel's recent blog post on The Positive Legacy of C++ and Java has opened a small can of worms on the Internet. The argument is on operator overloading[1]: tool of Satan or road to bliss? The arguing that's resulted is the usual well thought out, reasoned debate I've come to expect from software engineers. Which is to say, not at all.

Explicit threads are undisciplined. They need some structure to keep them in line. In this column, we're going to see what that structure is, as we motivate and illustrate best practices for using threads -- techniques that will make our concurrent code easier to write correctly and to reason about with confidence.

In a recent discussion, there were assertions that C++ was a poorly-designed language. I was on the C++ Standards Committee for 8 years, and saw the decisions take place. I think it's helpful to understand the language choices for both C++ and Java in order to see the bigger perspective. That said, I hardly ever use C++ anymore. When I do, it's either examining legacy code, or to write performance-critical sections, typically as small as possible to be called from other code (my preferred approach is to quickly write an app in Python, then profile it and if necessary improve performance by calling small portions of C++ using Python's ctypes library). Because I was on the C++ Standards Committee, I saw these decisions being made. They were all extremely carefully considered, far more so than many of the decisions made in Java.

Today I have compiled a list of ten programming languages with their application domains and little historic background. Also I have mentioned the names of the developers of these languages along with their little biography. I hope you will find this article quite useful. The list is developed by researching through language websites, developers??? biographies and other related search engines. These programming languages include C and C++ programming language, Java, Pascal, Python, Basic programming language, COBOL, FORTRAN, Lisp and Perl programming language. There are lots of other languages which I did not include as those languages are not commonly used or not developed by individuals or designed for web development which I will cover in upcoming articles.

So, two different posts crossed my transom recently, that I felt I had to respond to. First, and most egregiously, there???s The Daily WTF???s Programming Sucks! Or At Least, It Ought To. Then there is this blog post on Why Functional Programming Doesn???t Catch On. I am of the opinion, having covered much of the computer industry one way or another, that there are no non-trivial, uninteresting problems. The reason is just this- any problem that is boring, trivial, and/or mechanical should be done by the computer. I mean, come on, people! We???re programmers. If anyone anywhere should be able to harness the power of computers to make our work easier, it should be us programmers- the ones harnessing the power of computers to make everyone else???s work easier!

What does the volatile keyword mean? How should you use it? Confusingly, there are two common answers, because depending on the language you use volatile supports one or the other of two different programming techniques: lock-free programming, and dealing with 'unusual' memory. (See Figure 1.)

One issue with the common C compilation model is that it can easily lead to unnecessary coupling between files. This coupling can require users of an API to either directly or indirectly include unnecessary header files. These additional header files may cause frustration as users attempt to figure out what additional header files or include paths are needed to use the API. Even if your header file includes the necessary header files or your build environment centralizes all header files in a single location, these additional header files can still be problematic as they can lead to longer compile times and add additional symbols to the global namespace of the translation unit, which increases the chance of conflicts.

Again if you understood that, then you can propbably see that the performance measured has more to do with execution envrionments than languange differences.
