Hereby I am starting a series of articles about the future concept in programming languages (also known as promis Es or delays) with a working title: back to the future. Futures is very important abstraction, even more these day than ever due to growing demand for asynchronous, Eve Nt-driven, parallel and scalable systems. In the first article we'll discover most basic java.util.concurrent.Future interface. Later on we'll jump to other frameworks, li

Linux is the Swiss Army knife of file systems, and it also offers a wide variety of storage technologies for both desktops and servers. Beyond the file system, Linux incorporates world-class NAS and SAN technologies, data protection, storage management, supp Ort for clouds, and solid-state storage. Learn more on the Linux storage ecosystem and why it's number one in server market share. Linux is many things, and its power lies in it ability to flexibly support vastly different usage models. But

the operations-oriented systems built by Python imply security features such as firewalls and connection management.Python lacks good concurrency support:Referring to Python, the Python Gil (Global interpreter Lock) will certainly be mentioned, and it will certainly question "Python lacks concurrency". This is really not good to say. It's only easy to see.Python has a large number of concurrency primitives, including generators,greenlets,deferreds and futur
