  TIOBE : Objective-C overtakes C++


TIOBE recently released the programming community index for July. From the index,we can find that the biggest change is that Objective-C overtakes C++ as the 3rd most popular language among programmers. Because of the popularity of iPhone and iPad, Objective-C is used by more and more mobile developers who want to develop apps for Apple products. Also, many developers are willing to develop apps for Apple since they can gain more profit on Apple platform than on Android platform.C++ is mainly us...

  Finding selected checkbox items in a JSF dataTable


This is one of those problems that I couldn’t find a complete example for when I needed it, so hopefully this will save somebody else the extra time it took me to piece it together. We frequently need to have data tables in our UI, and allow the user to select a subset of those items for action. In JavaServer Faces, this means having a DataTable, each row having its own checkbox. But when the action is triggered, how to we find which items the user has selected. The first step is to add a...

  TIOBE : Where is that next big programming language?


TIOBE has released the Programming Community Index for May 2012 a bit late. The top 3 languages do not change compared to last Month TIOBE : C overtakes Java as the No.1 programming language, they are still C,Java and C++. However, the share of Java is continuing dropping, Objective-C is steadily rising  Other languages which have rising trend are Visual Basic.NET,PL/SQL and Logo.The last 8 years not much has changed in the top 10 of the TIOBE index except for Objective-C (in) and Delphi...

  3 meanings of Stack


We may frequently see stack when we read programming books. But many times we may be confused about the different meanings of it. This term actually has three common meanings. Here we explain the three different meanings of Stack in programming. 1. Data structure The first meaning of Stack defines a method for storing data. Its feature is LIFO9Last In First Out). In this data structure, data are accumulated level by level. The data last put in is added at the top of the stack. When using the dat...

  A Toast to C


At Cloudmetrx, we use a lot of C. So given the recent passing of UNIX legend Dennis Ritchie, the creator of the C language, we think a toast to C is only fitting.Our extensive reliance on C is especially unusual considering the other languages in our stack – Clojure, Node.js, and other hipster platforms. We aren't predisposed to using older, "venerated" technologies simply because they're older and venerated. But when it comes to high-performant computation, there's just nothing like C. Some w...

  Esmerelda's Imagination


An actress acquaintance of mine—let's call her Esmerelda—once said, "I can't imagine being anything except an actress." To which the retort was given, "You can't be much of an actress then, can you?"I was reminded of this exchange when someone said to me about Go, "I can't imagine programming in a language that doesn't have generics." My retort, unspoken this time, was, "You can't be much of a programmer, then, can you?"This is not an essay about generics (which are a fine thing and...

  Introduction to DTLS(Datagram Transport Layer Security)


Secure communication has become a vital requirement on the Internet. Lots of information transferred through the Internet are sensitive data such as financial transactions, medical information, media streaming etc. To ensure security of data transferred on the Internet, a few secure protocols have been designed including SSL/TLS and IPsec. Many large websites in the world have adopted TLS. Apart from SSL/TLS, there is some other protocol designed to be used in special cases. One of them is ...

  Hail the return of native code and the resurgence of C++


Programming language trends come and go. First, Java is the hot new language, then it's Python, then Ruby steals the limelight, then it's back to JavaScript. But the latest language darling is probably the last one anyone expected. Believe it or not, 2011 could be the year of C++. Last week, the latest version of the ISO C++ Standard was approved by unanimous vote. It's the first major revision of the language in 13 years. Now officially known as C++11, the new standard introduces features desig...

  Tricks with Direct Memory Access in Java


Java was initially designed as a safe managed environment. Nevertheless, Java HotSpot VM contains a “backdoor” that provides a number of low-level operations to manipulate memory and threads directly. This backdoor – sun.misc.Unsafe – is widely used by JDK itself in packages like java.nio or java.util.concurrent. It is hard to imagine a Java developer that uses this backdoor in any regular development because this API is extremely dangerous, not portable, a...
