  • 5 easy tips to accelerate SSL – Unhandled expression – SSL is slow. These cryptographic algorithms eat the CPU, there is too much traffic, it is too hard to deploy correctly. SSL is slow. Isn’t it? HELL NO! SSL looks slow, because you did not even try to optimize it! For that matter, I could say that HTTP is too verbose, XML web services are verbose too, and all this traffic makes the website slow. But, SSL can be optimized, as well as everything!

  • Security Tips for Apache Web Server – Debian-based Systems – Apache is one of the most widely spread Open Source web server for web hosting in Internet due to its stability, robustness and rich variety of modules and features. Due to its popularity, Apache comes with pre-build binary packages for almost all major Linux distributions and can also be installed on other Operating Systems such as Unix, Windows, Mac OSX, BSD etc. However, a basic installation of Apache on Linux systems, by default, doesn’t offer a full protection against attackers, so a few security measures must be taken in order to protect your machines, web servers and web documents against such types of malicious attacks. This article will provide you a few tips on how you can secure and protect Apache Web Server installed on Debian-based Linux distributions.

  • 10 Ruby One Liners to Impress Your Friends – Someone came up with a list of 10 one-liner examples that are meant to showcase Scala’s expressiveness. A CoffeeScript version quickly emerged, so I thought I’d publish a Ruby one. I find Ruby’s syntax to be a bit cleaner than Scala’s, but the substance (at least as far as these examples are concerned) is relatively similar.
  • Ruby development for system administrators | Linux User – Most Linux and UNIX system administrators use a diverse mix of shell scripts and tools like grep, awk, cut and so on. The classical approach has proven its merits, but these scripts are generally not easy to read or to maintain. One solution is to use a real programming language for system administration tasks. In a complex environment, system administration can become much easier with a real programming language instead of shell scripts. Traditionally, Perl has been very popular among sysadmins, but some people maintain that this is not much better than shell.

    In this article, we choose Ruby, a feature-rich but simple object-oriented programming language known from the popular web application framework Ruby on Rails. T

  • Modern Perl, by chromatic – Onyx Neon Press – Modern Perl is one way to describe how experienced and effective Perl 5 programmers work. They use language idioms. They take advantage of the CPAN. They're recognizably Perlish, and they show good taste and craftsmanship and a full understanding of Perl.

    You can learn this too, whether you've dabbled with Perl for a decade or someone just handed you this book and said "Fix this code by Friday."

  • Useful commands for Windows administrators – Managing a Windows 2000 Active Directory with about 100 servers, over 1500 computers and 35 sites, the following commands often helped me answer questions or solve problems.
    Most commands are "one-liners", but for some I had to make an exception and go to the right directory first.

    These commands could all be used in batch files, though some may need some "parsing" with FOR /F to retrieve only the required substrings from the displayed information.
