eyeOS: Free Web Desktop For Everyone
eyeOS is a web based desktop which offers some nice features. Web desktops will never be an alternative to real desktops but they come in handy in a few situations. When you are not in front of your system or you don’t have a USB drive to work remotely these can be useful.
eyeOS is a open source we desktop software, you can download it and host it for yourself if you find it useful for you. It offers many features from file hosting, music, videos to RSS feed reader. You can use the free public server by registering at eyeOS or try the demo to see what it has to offer.
Some of the interesting features include a POP3 email client where you can setup email and read. It also supports Gmail. It has most of the features you will expect in a OS including Calendar, spreadsheets, contacts, files, RSS reader, calculator, chess, docs, presentations, ftp, notes etc. All these may not be useful but some like Gmail, ftp, RSS reader are quite useful.
Check out the demo to see it in action. ZImDesk is a related application

Hack boot screen

Some distros have sexy boot screens, some have basic, boring ones. Here’s what I get from a default installation of ubuntu…

What a yawn! But there’s an easy way to spice them up. Add either or both of the grub-splashimages…

o add a new splash image, edit /boot/grub/menu.lst and add the line
splashimage /boot/grub/splashimages/FILENAME.xpm.gz
DIY Splashing
If you find the above selection a bit dull, its a doddle to create your own.
The images used by the grub bootloader must be in X PixMap (.xpm) format and may or may not be compressed with gzip (.gz). What’s more, they have to be sized 640×480 pixels and have no more than 14 colours(!?). Fortunately, if you have ImageMagick installed, this command will do the whole conversion for you…
convert infile.jpg -resize 640x480 -colors 14 -depth 8 outfile.xpm.gz
(Note that you can use pretty much any graphic with convert. You’re not restricted to JPGs.)
Not every image converts nicely. That 14-colour format can turn great images grainy — or worse — so here’s a quick batch file to convert a bunch of randomly named JPGs into .xpm.gz format. To use it, create a new folder, copy in the files you want to try, save the following as xpm_convert.sh, and make it executable by typing chmod +x xpm_convert.sh in a console window.
#!/bin/bash
FILE_NO=”1″
for i in *.jpg
do
echo Converting $i
convert $i -resize 640×480 -colors 14 -depth 8 $FILE_NO.xpm.gz
FILE_NO=`expr $FILE_NO + 1`
done
Running the program with ./xpm_convert.sh will create a bunch of consecutively numbered .xpm.gz files, which should be copied to /boot/grub. Why use numbers instead of names? Because it makes it easier to test the new files.
When you reboot, hit “c” when the boot menu appears. This will take you to the a grub command line. Now type splashimage /boot/grub/1.xpm.gz to try out the first of your new images. Then try splashimage /boot/grub/2.xpm.gz to test the second one, and so forth. There’s no need to do a full reboot and change menu.lst every time!
A couple of other notes:
* The above doesn’t seem to work unless your menu.lst already contains a working splashimage.
* You can use auto-complete on the grub command line, so instead of typing the whole command you can type sp <tab> /bo <tab> g <tab> etc.
