Grau DataSpace 2.2

I think it is time to write something about the current edition of GDS 2.2. A lot has been changed since my last post. Version 2.2 comes with a new design of the web UI. I think it is much easier to use than the first edition.


We removed the toolbar and moved the complete functionality into conext menues. A quota bar shows the available disk space.


An inline preview is created for many common file formats.


We added the possibility to define roles, global and private groups of users by a data space admin. Desktop sync clients are available for Windows, Linux and MacOSX. They are based on the CMIS protocol which gives us interoperability options with SharePoint, IBM Connections and major DMS systems.

The native clients for iOS and Android are also using the CMIS interface.


All our clients are released under an Open Source license to be able to modify them and adapt them to special requirements. The source is available on GitHub (http://github.com/opendataspace)

Secure Filesharing in the Cloud

Filesharing in the cloud is nothing new. Many people are already using DropBox or other services to synchronize their files between several devices or to share them with other people. On the other side big companies like IBM are banning these sevices because of security concerns (Technology Review).

So what to do if you are a small company or an individual who needs this kind of services? Fortunately, there are alternatives to DropBox and iCloud available, which can be installed on premise or at a secure place.

One of these is the a solution called DATA SPACE which has become a joint venture between SSP-Europe and GRAU DATA. These companies have joint forces to provide a Java based, enterprise class solution for sharing files inside larger organizations, partners and individuals.

Today the solution is already deployed at several customers, one of them is Orange Austria (Orange Data Space). GRAU DATA is offering the software as GRAU DATA SPACE for enterprise customers.

The DATA SPACE solutions offers a WebGUI and mobile native clients for Android, iPhones, iPads. A Blackberry version for OS7 and BB10 is under development. A DATA SPACE offers the possibility to define data rooms where users can share their files. Administrators can define sub rooms which can be assigned individually.

The files can also be accessed via WebDAV from any desktop operating system. Currently a CMIS interface is under development which is also used for the desktop sync clients for Windows, MacOSX and Ubuntu.

All files are stored on an encrypted file system. Optionally, all files can be encrypted individually during the upload by keys which are stored in a HSM (hardware security module). The solution will get a data privacy certifcation from the ULD.

FreeRDP becomes cloudy

As I mentioned in some of my former posts, the FreeRDP project makes progress in becomming a platform for cloud based desktop services.

Fritz Elfert started a project called FreeRDP WebConnect. The project provides a gateway which allows a JavaScript based browser client to connect to a RDP server. The connection between the client and the gateway is based on websockets.

The JavaScript client implements a virtual keyboard for the RIM playbook.

Click here, to connect your browser to a Windows 2008 server.

UPDATE: The FreeRDP project (powered by ThinStuff) published a Android and an iOS version in the app stores. Here you get the details.

Android-x86 - the Linux Desktop for the Masses

Some moths ago I ordered the cheapest Asus EeePC, the X101. It has no LAN port and no hard disk. It came preinstalled with the dead Meego OS. I replaced it with Ubuntu successfully.

Two weeks ago I decided to replace Ubuntu with the release candidate of Android-x86. It works out of the box on most Asus netbooks.

The performance of my Xoom tablet feels slower than Android-x86 on the X101. Android-x86 is based on Android 4 and comes with most of the standard Android apps (mail, calendar, music player).

Some further apps are easy to install from GooglePlay (the former Google market):
  • DropBox
  • Radio.de
  • IM+ (commercial instant messenger)
  • Google Reader
  • Google Maps
  • Tagesschau
  • Audible
  • Kindle reader
The most apps are working. Some of the are starting with rotated screen, which makes the useless. Some others are not listed in GooglePlay. The Kindle app has problems when you try to turn over a page. Native keyboards are obviously not supported yet. Switching to a German layout did not work for me.

The overall impression of Android-x86 is a very good option for netbooks in my opinion. I think it will bring Linux finally to the masses!

JavaScript, the Lingua Franca of the Internet

The performance of JavaScript is getting better and better. I think this will help to get rid of traditional operating systems in the near future.

There are several demos available where you can see the power of JavaScript:
Fritz Elfert will try to develop a RemoteFX decoder in JavaScript for the Open Thin Client Alliance together with the FreeRDP project, sponsored by BaWue goes mobile. The goal is an Open Source RDP client, which implements as many features as possible in a browser.

UPDATE: Telefonica announced a new device which focuses totaly on HTML5, called OpenWebDevice. Qualcomm will deliver the silicon, Mozilla delivers the boot2gecko enginge. Is this the first real Andoid killer?

UPDATE: Scripting languages are getting nearly as fast as C++. A canadian company called Fabric Engine provides a ultrafast JavaScript and Python implementation. The engine can be licensed under AGPL and a commerical license. It supports multithreading an can be used for Python and JavaScript. Here are some benchmarks.

UPDATE: Here is the first screencast of a JavaScript webgateway for FreeRDP: http://goo.gl/hFaib. The source code will be released on LinuxTag 2012.

UPDATE: Here it comes: a audio and video SIP client written in JavaScript. I think the time of a classic Windows PC is finally over.

UPDATE: Here you find a UNIX shell written in JavaScript.
