Do we really need so many new programming languages? There is no doubt that the choices currently being made by developers are quite rich. command-type languages, functional languages, object-oriented languages, dynamic languages, compiled language interpretive languages, and scripting languages and so on seem to have completely covered all the tasks we might face, and few professionals today have been able to understand all the languages. However, new languages are still springing up at an alarming rate. Some are designed by students or enthusiasts in the form of personal projects, others from large it vendors. Not even ...
There seems to be a plot in a thriller that says, "It's easy ... It's so easy. "And then all things began to fall apart. When I started testing the top-tier Java cloud Computing in the market, I found that the episode was repeating itself. Enterprise developers need to be more concerned about these possibilities than others. Ordinary computer users get excited when there are new scenarios in cloud computing that make life easier. They will use cloud-based emails and if the emails are lost they can only shrug their shoulders because the electrons ...
National Day holiday in the past, Tiobe released the October programming language rankings, together to see the ranking situation: the first three no significant changes, still for C, Java, C. Last month, I mentioned that Java, C + + fell to the lowest point in history, as can be seen from the chart, the share of these two languages is still falling. This month's most noteworthy is that Google Dart first entered Top 20, ranked 17th, the table so far ...
The "Editor's note" machine learning seems to have turned from obscurity to the limelight overnight, as well as more open source tools for machine learning, but the challenge now is how to get developers interested in machine learning and the data they are prepared to use to actually use them, This paper collects the common and practical open source machine learning tools in several languages, which is worth paying attention to, which is from InfoWorld. The following is the original: After decades of development as a professional discipline, machine learning seems to appear overnight as a popular business tool ...
This article covers some JVM principles and Java bytecode Directives, recommend interested readers to read a classic book on the JVM, Deep Java Virtual Machine (2nd edition), and compare it with the IL assembly directives I described in ". NET 4.0 object-oriented Programming". Believe that readers will have some inspiration. It is one of the most effective learning methods to compare the similarities and differences of two similar things carefully. In the future, I will also release other articles on personal blog, hoping to help readers of the book broaden their horizons, inspire thinking, we discuss technology together ...
