Twitter is a social networking platform that keeps you in conversation by allowing you and your friends to follow each others' updates. The service lets users post and read 140-character updates, called tweets. With Twitter, you can do social networking on the fly, from your mobile phone or at your desktop, from a Web browser or a Twitter client. Twitter clients make the service more usuable by automatically checking for updates from your friends and allowing you to easily post your own updates. I tested four Twitter clients for Linux on a desktop running Ubuntu Hardy Heron.
One of the goals of the Software Freedom Law Center (SFLC) is to become a center for education in free and open source software (FOSS) legal issues. As part of this effort, the SFLC has already published "A Legal Issues Primer for Open Source and Free Software Projects." Its latest effort in public education, released last week, is "A Practical Guide to GPL Compliance," a 15-page guide for FOSS projects on how to avoid violations of the GNU General Public License (GPL) and Lesser General Public License (LGPL). The guide is a practical summary of its subject, but its wording is unnecessarily legalistic, and its structure and omissions sometimes fall short of the goal of being a standalone reference.
For enterprise system administrators looking for interoperability with Microsoft Exchange, but not the high costs associated with it, PostPath email and collaboration server could be a smart business investment. Boasting interoperability with Exchange environments for a third of the cost, thanks to its use of the Postfix mail server and many other open source components, PostPath provides drop-in capability and compatibility with Exchange environments without the need for making changes to Outlook on the client side. Being compatible with Exchange means that it can be managed using Microsoft's Active Directory infrastructure. The latest version, PostPath v3.1.2, adds support for Blackberry Enterprise Server and ActiveSync, allowing you to use mobile devices to access your email.
If you like first-person shooters, you'll love Sauerbraten. This open source game might not have the visual finesse of other FPSes, but what it lacks in the graphics department, Sauerbraten more than makes up for with its various single and multiplayer modes, including an experimental role-playing game mode, and a unique WYSIWYG in-game map editor. Sauerbraten blends the best of FPSes like Quake and Max Payne to give you a unique gaming experience.
The bookmark tagging feature introduced in Firefox 3 is not particularly difficult in use: when bookmarking a Web page, enter the tags you like into the Tags field of the bookmarking dialog window and you are pretty much done. Tagging provides a more flexible way of keeping track of bookmarks than traditional folders. The folder-based system provides an "either/or"-solution to filing bookmarks. For example, you could place a bookmark for an article about installing OpenOffice.org on Puppy Linux in either a Linux or OpenOffice.org folder, but not in both. With tags, you don't have this problem: you can assign as many tags as you like, so the bookmark becomes filed under several categories at the same time.
Organizations have many ways to connect, collaborate, and keep in touch with co-workers, team members, and colleagues -- which can lead to multiple logins and user accounts, services spread across the Web, or services that are simply not accessible to all team members on various types of devices. Kablink (formerly ICECore) recognizes that centralization and accessibility are major components to successful project collaboration, and its latest offering is worth a project leader's second look.
Ulteo Application System is a GNU/Linux distribution based on Kubuntu and designed to work with the Ulteo Online Desktop service to provide you with an automatic offsite backup and file synchronization between live CD instances. It attempts to require as little user configuration and maintenance as possible, and provides several unique features that set it apart from being "just another distribution."
Piracy notwithstanding, there are some good, valid reasons for making a backup of a DVD. K9Copy, a utility for copying DVDs, receives high marks in many forums, so I took it for a spin -- and found out its reputation is deserved.
There are numerous documents, tutorials and guides detailing the workings and usage of cron, the de facto tool for scheduling jobs on Linux. While traditional cron jobs are executed at set times, inotify cron, or incron, is a cron clone that watches the filesystem for specified changes and executes the relevant commands. You can set incron to monitor a particular file or directory for changes and schedule jobs for when those changes occur.
According to its past and present marketing, Foresight Linux has three claims to fame: Its user-friendliness, its use of the Conary package management system, and its role as a showcase for the latest in GNOME. In practice, its latest 2.0.4 version is not more user-friendly than any other GNOME-based distribution -- if anything, it is slightly less so because of its limited software selection and package management -- but its other claims are enough to make Foresight one of the more distinctive modern distributions.
Linux has no shortage of audio and video players, but if you want to devote your whole system to multimedia use, you need the XBMC (formerly Xbox Media Center). Although initially designed for the Xbox gaming console, XBMC has been ported to other platforms. The alpha version of the Linux port of XBMC that I use is quite usable, especially for video playback, despite the fact that not all XBMC features have yet been ported.
Scalix collaboration platform, with its latest release version 11.4, aims to be a good alternative to Microsoft Exchange. Based on the HP OpenMail platform, discontinued by Hewlett-Packard in 2001, it has been further developed by Scalix and now acts as an enterprise email and group calendar server with the option of integrating systems like ERP, CRM, and billing into the Scalix system using its open API. It is compatible with most LDAP authentication mechanisms, such as those in Windows Active Directory, Novell eDirectory, and Red Hat Directory Server. The most prominent feature of Scalix is its Exchange compatibility; you can use an Outlook client to access the Scalix platform. Scalix also provides an AJAX-based client that is nearly identical to Microsoft Exchange Outlook Web Access (OWA). Aside from Outlook compatibility, Scalix also claims to coexist peacefully with other existing Exchange email systems.
A shift from multi-core power-gobbling monsters toward whisper-quiet systems with single-digit power consumption is rippling through the desktop market. This trend plays right into the hands of a Paris-based company called Linutop, which offers a miniature Linux-based desktop system. The latest version of the machine appeals to customers who are in the market for a machine with green credentials and low maintenance costs. After testing one myself, I found the tiny desktop has a lot going for it.
NimbleX, a Slackware-based distribution, advertises itself as "the new wave of Linux." However, what is appealing in NimbleX -- its speed and small footprint and the resulting selection of alternative software choices -- will likely strike veteran GNU/Linux users as being very old school. By contrast, its limitations -- too little attention to such aspects as the installer, packaging, and security -- seem all too modern, being reminiscent of other distros intent on commercialization or emulating Windows, even though NimbleX is a community distribution and largely a labor of love for Romanian developer Bogdan Radulescu.
Gmail, Google's popular Web mail application, is already full of useful features all on its own. But Firefox users can further customize Gmail with a variety of add-ons. Some only change the appearance, while others add functionality that makes Gmail more like a personal planner than just a plain old email application. Let's take a look at three Firefox add-ons for Gmail.
I first heard of gOS when it was chosen to power the $199 Wal-Mart gPC. The third iteration of the OS, gOS 3.0 "Gadgets" Beta, was released last week. It's a great Web-focused desktop, but it doesn't offer much to experienced or current Ubuntu users.
gOS is an interesting Ubuntu GNU/Linux offshoot. We've reviewed it and interviewed gOS founder Daniel Liu. Now, in this video, you can see the distro in action before you decide whether it is something you want to download and play with for yourself. Remember that this video was made with a beta version of gOS Gadgets 3, so some features don't work correctly that will almost certainly be just fine in the final version. That caveat given, here's the video.
Quantum GIS 0.11.0, released last month, is a free geographic information system (GIS) application released under the GPL that runs on multiple platforms, including Linux. QGIS can read, edit, and export common GIS file formats. After installing it and using it to work with existing data layers available from official data repositories, performing common spatial analysis tasks, and sharing files and data with the commercial GIS products, I found QGIS has the potential to be a viable alternative to proprietary commercial GIS programs from the likes of ESRI and Intergraph/Geomedia.
Who says you have to give up your must-have Windows applications when you migrate to Linux? If you can't leave some crucial Windows program behind, you can run it using CodeWeavers' latest version of CrossOver Linux.
Pardus is a GNU/Linux distribution funded and developed by the Scientific and Technological Research Council of Turkey. Pardus has its own unique installer, package manager, configuration wizard, and control panel. This originality, and the developers' attention to detail, make Pardus worth a look.
