• if you are an beginner or intermediate php developer looking for a base where to start coding your own twitter display.
• if you are already experienced in copy & pasting php code into your wordpress blog, for example, expanding the functionality of your sidebar or your page template

• This is how it looks

So you say: What do I need another free map service for? Is Google Maps not enough?.
Check out this comparison by Bodenseepeter [in German, illustrated]. He analyzed the extend of the two map services usinng ten examples worldwide. For example Cape Town:

Update: Sweetcron Beta is out for evaluating:

• Sweetcron program files
• Seetcron documenatation

It’s closed beta right now, but the developer, Yongfook, promises to launch it soon. It is going to be 100% open source and offers some more features:

• Automated Imports: Uploaded a photo to flickr? Bookmarked a new site? In a few minutes it will show up on your blog, thanks to the power of RSS feeds
• Easily Customisable: Edit simple templates to change your Sweetcron look.
• Self Hosted: You can keep alll the data safely on your own server and run Sweetcron on your own domain.
• Fully extensible: Write your own php classes and slot them right in!

No need to burn a CD. Just run the installer, enter a password for the new account, and click “Install”, go grab a coffee, and when you are back, Ubuntu will be ready for you. You keep Windows as it is, Wubi only adds an extra option to boot into Ubuntu. Wubi does not require you to modify the partitions of your PC, or to use a different bootloader, and does not install special drivers.

After starting the application, you have options for the user interface to choose from:

• Ubuntu with GNOME interface
• Kubuntu with KDE interface
• Xubuntu with XFCE [for older computers]

Then, Wubi starts to download the operating system from a Ubuntu server repository and installs it automatically regarding to your hardware. After rebooting, you can choose whether to start your computer into Windows or Ubuntu. As simple as making a sandwich.

Minimum requirements:

• 256 MB memory
• 5 GB harddisk space
• Windows 98, 2000, XP or Vista

Sounds great. I am trying it just now. Really curious if it can compete in the everyday system battle.

With the EFI V8 emulator it is possible to install Leopard’s kernel straight from the DVD that you purchased at the Apple store barring the addition of a few drivers to ensure that everything boots and runs smoothly

Psystar is marketing this as a cheaper and more expandable alternative to a genuine Apple Mac. I don’t know what these machines are capable of. We all think: Hopefully, finally, a legal MacOS Clone might hit the scene. Perhaps it will help people who don’t want to afford expensive Apple hardware to run Apple software on their cheap machines?

Actually, the OpenMac company Psystar clone is close to a Cease and Desist order tasked by Apple. Which basically means that Apple will make use of their copyright rules included in Leopards License Agreement:

You agree not to install, use or run the Apple Software on any non-Apple-labeled computer, or to enable others to do so.

Let’s wait and observe. Surely Apple will not tolerate that. Either by weapons of law or by technical regulations [That means non-compatible updates].

BTW: There is another open source project called “OpenMac” powered by Meshnetics, but this one regards to the Medium Access Control Layer and not to the Apple computer.

Here is something different:
Dietmar Offenhuber (Austria & Cambridge) and Gerhard Dirmoser (EnergieAG) created the Network Context Visualizer Semaspace. It’s made easy to understand by this video:

SemaSpace is a fast and easy to use graph editor for large knowledge networks, specially designed for the application in non technical sciences and the arts. It creates interactive graph layouts in 2d and 3d by means of a flexible algorithm. The system is powerful enough for the calculation of complex networks and can incorporate additional data such as images, sounds and full texts.

Get a grip here: Two examples to try out for yourself (it’s fun to move around data in 3-dimensional space). You need to install Virtools 3D plugin in order to view this:

• 25 years of ars electronica
• Gedankenraum

Well, in 2009, the music service Musicovery might switch it’s interface to 3D with tech like that.

Warum? Nun, OpenXChange ist zwar OpenSource, jedoch gibt es eine kommerzielle Variante, die Advanced Server Edition, zu der man Installationssupport und einen Wartungsvertrag erhält, die jedoch weit unter den astronomischen Preisen für Microsofts Exchange-Software bleibt. Eine grob berechnete Übersicht:

Weiterer Vorteil der Bezahlversion von OpenXChange ist die Kompatibilität mit kommerzieller Desktop-Kommunikations-Software wie Outlook und Entourage. Zugleich kann OpenXchange (die Natur der Sache) beliebig konfiguriert und durch freie Module erweitert werden. Selbstverständlich können Linux-Kommunikatoren (Kontakt und Evolution) auch mit dem XChange-Server anbändeln.
Eine Online Demo der komfortablen Web-Oberfläche überzeugt: Die Funktionen sind sauber implementiert:

• E-Mail-Kommunikation (inkl. AJAX-basiertem Webclient)
• Kalender mit Terminverwaltung (iCal-Standard)
• Dokumentenmanagement
• Wiki und Portalseite
• Anbindung an MS Outlook
• Webserver
• Datenbank
• Backuptool, Anti-Virus, Anti-Spam

Installiert wird Open-XChange auf einem Linux-System. Das kann ein lokaler Server oder ein Webserever sein, man braucht natürlich schon mehr als nur Webspace. Ein dedizierter Server (virtuell oder physisch) muss es schon sein.
Ein Vorteil für erfahrene Admins: Es gibt natürlich auch Gratispakete, das nur noch an die entsprechende Umgebung angepasst werden muss. Und das ist dann tatsächlich gratis. Im OpenXchange-Forum habe ich ein CD-Image einer Out of the Box Version mit Zusatzmodulen gefunden.

Noch besser ist es, als Unternehmen am Beta-Programm der OpenXChange Express-Edition teilzunehmen. Man erhält den ersten Release Candidate frei zum Download. Dann: Einfach von CD installieren, Zugänge einrichten und los geht’s. Die Konfiguration darf da ruhig eine Woche dauern Die Installation von CD ist dialoggeführt und nicht schwerer, als Windows XP aufzuspielen. Ein Segen, wenn man sich die monetäre Ersparnis ins Bewusstsein ruft.

1und1 nutzt bereits OpenXchange für ein gehostetes Mietangebot, das heisst dann 1und1 XChange. Immerhin noch relativ günstig, aber die laufenden Kosten sind doch sehr hoch, da pro User abgerechnet wird.
