Squid is a caching proxy server that can provide enhanced performance for HTTP and FTP. Squid will cache commonly accessed sites so that it can improve performance by 10-20% for Internet connections.

Here is the Official Squid Site: http://www.squid-cache.org/

Squid is compliant to the Harvest Cache architecture and uses the Inter-Cache Protocol (ICP) to transfer data between peer and /parent/child servers. Squid can accelerate traffic from the inside network to the Internet or it can be employed to act as a front-end accelerator for a Web server, increasing access to the web pages on the server.

For the past few days I have been looking for a proper i18n (internationalisation) and l10n (localisation) method for PHP. PHP has quite a few locale aware functions such as strftime and sprintf. In combination with gettext this can work quite well. The major downside is that you need to install all the locales that you want to support on your server. Want to serve your websites in Russian? Then you need to generate a Russian locale system-wide. That won’t work when you’re on a shared hosting account somewhere.

PHP6 is promising to solve that problem with the intl functions. Even better, the intl functions are also available as a PECL extension and works on PHP 5.2.4 and newer. Debian Etch currently packages PHP 5.2.0 which is too old, but Lenny—Debian’s upcoming version—is up to PHP 5.2.6. There is no package (yet) for php5-intl in Debian Lenny but building and installing the extension yourself is really easy. Here’s a short tutorial.

Voice over Internet Protocol (VoIP) has emerged as a popular technology for modern voice communications. Many organizations have replaced their analog or proprietary digital telephone systems with VoIP-based solutions. This allows the consolidation of telephone services into an existing IP infrastructure. In addition, using IP to host voice services lets the organization leverage existing expertise–while retaining all of the network’s management advantages. Though not without its disadvantages, VoIP provides a compelling option to those looking for a telephone solution.

This article will present a simple VoIP solution using Asterisk, an open source private branch exchange (PBX) product. It will show you how to install Asterisk, configure it using its LDAP backend, and connect to it using the Ekiga software VoIP client and a Cisco 7900 Series VoIP telephone to make calls.

My wife and I have been using (and collecting) computers for years, and we’ve shared this interest very effectively with our children. Now I am the victim of my own success: my household now has four physical computers, one of them dual boot. All are on a single internal Local Area Network (LAN) with five real users plus sundry administrative ones on each. Some of the computers are also running services. I also have two computers sitting in a box, which will probably be added to this mess soon, plus my wife plans to get a laptop. Like it or not, I now manage a network bigger than many small businesses! But I can’t afford to pay a system administrator, and the tedium of “network plumbing” is my least favorite part of computer technology. Surely, there must be a way to automate this mess?

Enter Zenoss…

Over time, organizations replicate, migrate, or add complexity within database systems, often times losing control of the quality of their data. When applications begin to fail because of invalid, corrupted, or out-of-date data, the free, GPL-licensed Talend Open Profiler can give data analysts, database administrators (DBA), and business users the ability to research data structures and improve data quality. Through the use of Open Profiler, users can be alerted to hidden inconsistencies and incompatibilities between data sources and target applications. Through data analysis, business users and technical analysts can communicate both data structure and content needs.

Life would be a lot easier if we could live in a Linux-only world and if applications never required data from other sources. However, the need to get data from Windows, MS-DOS, or old Macintosh systems is all too common. This kind of import process requires some conversions to solve file format differences; otherwise, it would be impossible to share data, or file contents would be imported incorrectly. The easiest way to transfer data between systems is by using plain text files or common formats like comma-separated value (CSV) files. However, converting such files from Windows or Mac OS results in formatting differences for the newline characters and character encoding. This article explains why we have these problems and shows ways to solve them.

The 7z (7-Zip) archive format offers good compression ratios and is an open source format. This and the favored 7-Zip graphical file archive tool for Windows have popularized the format.

A default Ubuntu installation can’t extract or create 7z files. A package is available in the universe repositories that makes working for these files seamless with Ubuntu’s existing archive tools.

Install 7z file archive support from the package p7zip (click the link to install), or by running the command below in your terminal:
