EyeOS
Some time ago, I had a look at YouOS and DesktopOne. Whereas DesktopTwo was more advanced, you need to have Adobe’s Flash plugin installed.
EyeOS is a good combination of both: No Flash needed and even a whole bunch of great features. The best: it is open source software and can be installed on any server you like.
Unfortunately it does not seem to have any session handling. So if you close your browser on computer A and switch to computer B, all applications have been terminated.

In first place, welcome to the eyeOS project. You’re about to discover a new work and organization method: A completely free (Open Source) Web Operating System running from your browser, where anybody can collaborate and expand it. If you want to see how is eyeOS, you can visit the screenshots section, or if you prefer it, watch the video from this page.

Google Gears

Google Gears (BETA) is an open source browser extension that enables web applications to provide offline functionality using the following JavaScript APIs:

Store and serve application resources locally

Store data locally in a fully-searchable relational database

Run asynchronous Javascript to improve application responsiveness

This is a presentation of Google Gears from the Google Developer Day in London some days ago:

BTW…the Google Developer Day took place globally in 10 different locations around the world. A lot more sessions can be found on the Google Developer Day Youtube Channel.

UltraMon
Found via lifehacker.com:

UltraMon is a utility for multi-monitor systems, designed to increase productivity and unlock the full potential of multiple monitors.

efficiently move windows and maximize windows across the desktop

manage more applications with the Smart Taskbar

control application positioning with UltraMon Shortcuts

multi-monitor support for desktop wallpapers and screen savers

mirror your main monitor to secondary monitors for a presentation

What I like most is the SmartTaskbar feature:

Each taskbar only shows applications from the monitor it is on, so you won’t have to search for an application after activating it. If you move an application to a different monitor, its taskbar button will be moved to the corresponding taskbar

In contrary to YouOS, DesktopTwo requires Adobe Flash beside a web browser. But as the Flash-plugin is installed on almost every computer, it is not a big restriction. Compared to YouOS DesktopTwo has many more features and functionalities. The applications are more advanced (for example mail client, rss reader, mp3 player(!)) and you even get your own email address and 1GB space on their server for storing mails, mp3s and any other files you would like to store.

Really amazing is, that Sapotek, the company behind DeskopTwo, seems to have implemented some kind of RDP protocol because you are able to use Adobae Acrobat Reader and the Open Office Suite.

So it is definitely worth to try out!

It works really great, but was unfortunately a little bit slow at the time i tried it. One might ask “Why would I ever need such a thing?”.

I think it could be pretty useful, if you are switching computers very often during the day. (desktop and laptop at home, workstation at the office, computers in internet cafés, etc) Most of the time I am running clients for mail, news and instant messaging all the time. With such an Browser-OS it would be possible to have all those applications running remotely and you are able to login from everywhere and use them almost like they are running locally.

Unfortunately this is currently not possible with YouOS, because you cannot logout without terminating all running applications. Hopefully this feature will be integrated eventually.

Another (wicked? ) idea would be to extend xorg’s xserver with an browser-capable client. If this would be possible, one could use a complete Linux system (for example) in a webbrowser. I would like (and use) that.

BTW…here is a screenshot of YouOS with some applications running:

(1) Add new source to /etc/apt/sources.list
deb http://packages.dotdeb.org stable all
deb-src http://packages.dotdeb.org stable all
(2) Install PHP 5 – WARNING: Plesk is currently not compatible to MySQL5! So make sure, that you do not upgrade your MySQL Installation.
apt-get install psa-php5-configurator
apt-cache search php5
…and install any of the php modules you want.
(3) THIS STEP IS PROBABLY NOT NEEDED ANYMORE WITH PLESK 8 AND ABOVE! So try out https://webmail.example.com first!
Fix Horde Webmailer:
apt-get install php5-pear
pear upgrade DB
cd /usr/share/psa-horde/pear
tar cvzf DB.backup.tar.gz DB.php DB/
rm DB.php
rm -R DB/
cp -R /usr/share/php/DB* .

(4) That’s it!

Well…this is the solution: Mindmap of Linux Distributions – Version 2
