JavaScript has steadily been among the most popular programming languages in the recent years. Numerous frameworks and development for popular platforms have secured the success and erased the memories of the nasty clichés of the past. The language grows, develops and becomes more logical, which certainly pleases many thousands of its fans.
For many years, I have been a fan of development for Windows and wrote pretty much about it to this best computer magazine ever. I switched to Mac OS and UNIX with time. Working in Mac OS, I set my mind to selecting a tool for creation of platform-independent programs. What should be preferred? Java? Mono? Too boring. I settled upon… Eiffel. For the following reason.
Information is currently gradually becoming “new oil” in terms of value. The only problem is that the volumes of data to be processed are growing by leaps and bounds. The sizes of files are sometimes larger than the hard drive, not to mention that RAM can’t cope, and interviewees receive increasingly scary tasks like comparing two petabyte files on the fly. But, fortunately for programmers, there is no need to make the machine choke on such amount of information, as iterators and generators can be used for threading, and there is also Python, a programming language which supports them perfectly. Would you like me to tell you about that?
Apache Tomcat is a server of web applications primarily used in commercial environment not only as an application platform, but also as a component of large projects related with providing of a web-interface. In corporate sector, security of information systems has the highest priority, while infrastructure stability ensures failure-free operation. Let us test a vaunted stability and security of UNIX daemons taking Tomcat as an example.
Since the beginning of dynamic Web development, а synchronization problem has emerged concerning a set of software programs, its versions and configurations in production and development environments. The developer of Vagrant has invented a new tool which is supposed to help solve the problem — Packer.
In a client-server architecture, Java applications are most often located on the server side, and web interfaces are created by separate groups of front-end developers using JavaScript. Java does not provide any useful tools to develop modern Web interfaces (Do you still remember what Java applets look like?) — neither in terms of design, nor in terms of the client-server interaction. But what if the entire client-server application was developed using Java? Why not to make the client part “native” to the browser in compliance with the most modern usability concepts?
Linux supports a highly versatile set of administration tools. On the one hand, it is good — users have options. But, on the other hand, this very variety is not quite suitable for a corporate sector, as there are often tens and hundreds of computers to be managed. Recently, quite a number of tools have emerged to simplify this task, and we will discuss one of them.
