  • Optimizing WordPress with Nginx, Varnish, APC, W3 Total Cache, and Amazon S3 (With Benchmarks) | danielmiessler.com – So I’ve spent the last couple of weeks tweaking my web server stack. I like my site to pop, and I’ve finally achieved a configuration that I’m somewhat happy with.

    In sum, I’m running Varnish as a front-end to Nginx which is running WordPress loaded with the W3-Total-Cache plugin. The W3-Total-Cache plugin is configured to use both memcached as well as Amazon S3 as its CDN. All of this sits on Ubuntu Linux with Linode as my host.

  • A Varnish Primer | danielmiessler.com – Despite the title, this article has nothing to do with painting. Here I'm going to talk a bit about the Varnish Cache — a web application accelerator designed to dramatically improve how quickly your website loads. Varnish works by caching and serving as much content as possible as "static", including dynamic results, e.g. blog posts from a CMS like WordPress.
  • Varnish best practices « Kristian Lyngstol’s Blog – A while ago I wrote about common Varnish issues, and I think it’s time for an updated version. This time, I’ve decided to include a few somewhat uncommon issues that, if set, can be difficult to spot or track down. A sort of pitfall-avoidance, if you will. I’ll add a little summary with parameters and such at the end.
  • Cain Manor | Setup logging for Varnish – So far, we’ve got Var­nish installed and have a cor­rect default.vcl. Now let’s make sure AWStats/JAW­Stats can read them.

  • 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.

  • Building a mail server on Debian 6.0 – The goal of this manual is to provide you with enough knowledge to feel confident in installing and maintaing your own mail server.

  • My Low End VPS Server – This document describes how to setup a Debian Linux VPS to replace your standard shared hosting account.  This document started out as a bunch of scribbles on scrap paper as I built a Virtual Private Server (VPS) into a fully functioning internet server.  It was notes on how I configured the server for the various pieces of the stack.  The need for the server was identified when I wanted to migrate my cPanel Shared Hosting account at Hostgator to a low end VPS for more control and freedom to run whatever software I wanted.  It was also a good opportunity to get back into Linux system configurations and serving web content.  As a collateral benefit, but not as the main drive, I was able to save a few dollars a month in web hosting costs.

    To ensure that your system will go back to the old kernel even if the new kernel fails (e.g. it panics), you can specify that GRUB should try the new kernel only once and boot the old kernel after that.<br />

  • How to build your own CDN using BIND, GeoIP, Nginx, Varnish | UNIXy – In this article, we shall outline the steps required to build a private Content Delivery or Distribution Network (CDN) using a VPS with Varnish Cache and Nginx.

To this end, all nodes participating in this network are going to be virtual machines (Xen, Virtuozzo, OpenVZ, etc). Should you have any questions or comments on the configuration of this CDN, please post them in this forum: http://www.varnish-cache.info/
  • Comandi testuali per i sistemi Windows – […] Al lavoro, spesso mi capita di dover eseguire le stesse operazioni su più server, più volte alla settimana. La maggior parte di queste operazioni riguardano utilità di sistema di Windows, come la gestione utenti di Active Directory, o quella del DNS od altro ancora. Certo, un collegamento sul desktop è comodo, ma in talune situazioni può tornare decisamente comodo (e più veloce) conoscere il nome degli eseguibili relativi ad un determinato pannello MMC, piuttosto che l’apposita applicazione contenuta nel Pannello di Controllo.<br />
    <br />
    Quello che segue è un elenco della maggior parte di questi comandi, tutti lanciabili direttamente dal pannello “Esegui” situato nello Start Menu di Windows. Alcuni di questi comandi possono essere distruttivi, portando addirittura alla formattazione del disco ed alla conseguente perdita di dati, per cui usateli solo se ritenete di essere in grado di farlo […]
