  • andihofmeister/squidGuard · GitHub – squidGuard cleanup/rewrite

    The version here is a rewrite of most of the code. While it provides (almost) all features found in SG 1.5, the configuration is not entirely compatible.
    This repostiroy does NOT contain an official version of squidGuard (see below)

  • eAccelerator – eAccelerator is a free open-source PHP accelerator & optimizer. It increases the performance of PHP scripts by caching them in their compiled state, so that the overhead of compiling is almost completely eliminated. It also optimizes scripts to speed up their execution. eAccelerator typically reduces server load and increases the speed of your PHP code by 1-10 times.
  • Server World – Build Network Server – This site explains how to build home server connected to internet with static IP address. You need to get at least one static IP address from your ISP. Please make sure the terms of use from your ISP, and Get one or some IP addresses if possibles. It's possible to build a network server, not with static IP address but with dynamic IP address by using Dynamic DNS, though. But I don't recommend it because there are some limits. It's the best to get at least one static IP address in order to build a network server, there is no limit. To get one static IP address is not so high costs. It's easy to build network server at your home.
    This site explains how to configure a server with commands basically, not with Graphical User Interfaces.

  • Nginx+PHP(FPM)+MySQL+Memcache+eAccelerator on Debian6 | Qi Yang – I recently rebuild my linux image on Linode, so I have to reinstall the LEMP stack again from ground.

  • Magento caching, APC, eAccelerator Memcached, files, sqlite, Vanish, what’s the … happen? | Alex Paradise – Magento is slow! It’s how start most of the article about Magento cache optimization. Yes, Magento is slow and this because of the way the code is written, extreme object oriented. Stackoverflow say “It is written in an Enterprise Java idiom” and there are right. Anyway, we can’t change anything about it and in one side that let us lot of flexibility.
    So, Magento IS SLOW! And what’s can we do? There is many thing to do, many, many. But the most important one is to work around the cache. I am searching for a cache solution and found so much different stuff like APC, eAccelerator, memcached, tmpfs, varnich, lighthttpd, nginx and so on… I will try to explain the different possibilities if found while my research and finished by the one I will implement[…]

  • MySQL-Galera cluster with HAproxy – Sébastien han – When I started working on Open Stack, I had to investigate about the HA of the nova component. Unfortunatly the nova configuration needed a single entry point to connect to the MySQL database. The solution that came to me was to use HAProxy on top of my existing Galera cluster…

  • calligrafia.org » il sito dell’Associazione Calligrafica Italiana – […] Nel settembre 1991 a Milano, un gruppo di calligrafi fonda l'Associazione calligrafica Italiana. Da allora il programma dell'Associazione è cresciuto con successo anche grazie ai contatti mantenuti con altre associazioni calligrafiche all'estero (in Europa e in America) garantendo così scambi di informazioni e soprattutto la possibilità di avvalersi della collaborazione di insegnanti di riconosciuta competenza. In questi anni l'ACI ha sicuramente ottenuto successi e risultati. Oramai la calligrafia è praticata anche in Italia, sono state organizzate mostre e avviati contatti con biblioteche e scuole[…]
  • Rajiv’s blog – I was in charge of scaling Dropbox for a while, from roughly 4,000 to 40,000,000 users. For most of that time we had one to three people working on the backend. Here are some suggestions on scaling, particularly in a resource-constrained, fast-growing environment that can’t always afford to do things “the right way” (i.e., any real-world engineering project ;-). If people find this useful, I’ll try to come up with more tips and write a part 2.

  • Generate large amount of test data « my two cents – I’m using the dictionary on linux systems to generate test data. The shell script below generates test data for MySQL, but similar concepts can be used for other database systems as well.
  • JQueryin | Switching Apache from Prefork to Worker MPM in RHEL / CentOS 5.x / Fedora 13 – I’m going to outline the process of switching from Apache’s default installation of MPM Prefork to that of MPM Worker. I will also be covering the proper installation of FastCGI (mod_fcgid) to further improve your server performance. This guide is ideally intended for individuals running on low-memory VPS servers as memory consumption will likely be far lower with the Worker MPM because it spawns threads as opposed to forking child processes. If you’re intentionally reading this article, you’re probably aware of the performance benefits gained.
  • Free PDF Reader – Sumatra PDF – Sumatra PDF is a free PDF, eBook (ePub, Mobi), XPS, DjVu, CHM, Comic Book (CBZ and CBR) reader for Windows.

    Sumatra PDF is small, portable and starts up very fast.

    Simplicity of the user interface has a high priority.

  • virtuallyGhetto: Ruby vSphere Console (RVC) 1.6 Released – Rich Lane the creator of Ruby vSphere Console just recently released RVC 1.6 which includes some new features and bug fixes. If you are a current RVC user, you can update to the latest version by using the "gem" utility. For those of you who are not familiar with RVC, it is console UI for vCenter Server and ESX(i) host and it provides a way to interact with your vSphere infrastructure like the vSphere Client but using a console shell. RVC can be installed on a Windows, Linux or Mac OSX system and it's built on RbVmomi which is an open source Ruby library/bindings to the vSphere API.

  • Monitor Your Website in Real-Time with Apachetop – How-To Geek – As a webmaster, I’ve often wanted to be able to see real-time hits as they arrive. Sure, Google Analytics is a wonderful package for looking at trends over time, but there’s a delay of a few hours there, and you really can’t see data like requests per second or total bytes.

    This is where the apachetop utility comes in. It’s a very simple command line utility that you can use to monitor traffic real-time. It accomplishes this by parsing the apache logfiles and displaying meaningful output to the screen.

  • Ashwin Jayaprakash’s Blog: The little gem that is BusyBox (for Windows) – As a Windows user (no shame) I have, for years searched for a simple GNU-like toolkit – grep, awk, tail and other such goodies enjoyed by Linux users. Yes, there's Cygwin but it's a beast – too big and a pain to install. Sometimes, I've even resorted to starting a Linux VMWare image just to run a simple awk script to munge some log files.

  • 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.

  • Squid kerberos authentication and ldap authorization in Active Directory « Klaubert’s Blog – The squid web cache include a authenticator for kerberos, it is simple to use, but the documentation is not very clear about how to make it work. Below some steps use by me to make Squid 3.0 Stable1 and Squid 2.6 Stable17 authenticate against Active Directory (Windows 2003 Directory Service) and also to make it make the authorization using Ldap. This setup was not used in production environment yet, so its possible to had some problems not seen by me or scalabilities issues.
  • active directory – Getting Squid to authenticate with kerberos and Windows 2008/2003/7/XP – Server Fault – This is setup with Squid 3.0, has also been tested with Squid 3.1 and should work with Squid 2.7. Your Windows user must be a member of the SQUID_USERS group in Active Directory (for this case anyway).

    On the Windows side, Windows XP and Windows 2007 have been tested against Windows 2008, and Windows XP against Windows 2003.

  • Open vSwitch – What is Open vSwitch?

    Open vSwitch is a production quality, multilayer virtual switch licensed under the open source Apache 2.0 license. It is designed to enable massive network automation through programmatic extension, while still supporting standard management interfaces and protocols (e.g. NetFlow, sFlow, RSPAN, ERSPAN, CLI, LACP, 802.1ag). In addition, it is designed to support distribution across multiple physical servers similar to VMware's vNetwork distributed vswitch or Cisco's Nexus 1000V.
