What is memcached?

But at first let us consider a small introduction. So memcached is a free and open high-performance distributed system for caching objects in memory. It is a storage of “key-value” type located in the operating memory and designed for small “portions” of arbitrary data (string values, numerical values, not infrequently serialized objects in the form of string values) such as results of queries to DB, results of API calls or generation of pages. In addition, memcached is a fully open development, is assembled and operated under UNIX, Windows, OS X and distributed under an open license. It is used by many popular web projects, for example, LiveJournal, Twitter, Flickr, YouTube, Wikipedia, etc. It is a normal network service with host-base authentication, which is operated in loopback interface on port 11211. memcached daemon supports UDP- and TCP-sockets and provides two different protocols for interaction with itself: text and binary. I suppose that this is all what we are to know about the patient so far.

In our work, we are faced with very different projects. In one way or the other, many of them could be called “high-load projects”. If you spend some of your spare time on categorizing these projects and discard such ordinary things as second-rate online stores while roughly grouping what is left, you can come up with an approximate classification. It includes four types of high load:

  • By the number of requests (banner networks);
  • By traffic (video services);
  • By logic (complex back-end calculations);
  • Mixed (everything that fell into several categories).

Now, let’s have a closer look at them.

Everything-you-need-to-know about python interpreters

Date: 11/02/2015

Author:

Python itself is, of course, a programming language. But many people mistakenly believe that Python is the very thing that comes with most of the *nix systems and can be launched by typing “python” in the console. That is, the interpreter (a specific version thereof) is associated with the language as a whole. Just like those guys who write on Delphi. But what does it really mean?
