This post reviews the five most popular free for download themes for Windows 7 available on the internet.

Themes for Windows often requires different types of heavy and resource demanding 3rd party software, e.g. like ThemeXP and others. In this post I have collected the most popular themes that do not require additional 3rd party software, but just works out of the box. Don’t bother on trying them with Vista or XP because they just wont work.

Win4lin, KVM, QEMU, Virtualbox and Xen are all widely used technologies, used in virtual servers. Fairly often a virtual server run from within a loop filesystem and generally start with a fairly small file (1GB is big for a normal file, but not when it is pretending to be an entire filesystem!)

However things often grow over time.

Here is a nice simple procedure for increasing the size of a loop filesystem, if the filesystem is ext2 or ext3 (the procedure should work for ext4 too, but I havn’t tested it yet)

1. Stop the virtual server that is using the loop filesystem
2. Add some extra space to your loop filesystem file
# dd if=/dev/zero bs=1024k count=1024 >> loop_image_file

This adds 1GB to the end of a file called loop_image_file (make sure to use the append output redirector >> not a single >, otherwise you’ll have an empty 1GB file!)

3. Force a check on the resized/increased filesystem
# e2fsck -f loop_image_file

4. Resize the filesystem within the loop filesystem file
# resize2fs loop_image_file

5. Start the virtual server again

Converting a hex color string (e.g. “AABBCC”) into numeric RGB (Red Green and Blue color model) values (e.g. 170,187,207) of the exact same color is quite simple. Here below i have craeted a small tool to perform to actual color conversion.

Use this converter to convert a set of RGB color codes into hex.

[...] Google released the Android code and I took a serious look at its internals… and found the solution for the licensing problem. It’s called Dalvik and it’s the new name of Sun’s worst nightmares.

Dalvik is a virtual machine, just like Java’s or .NET’s.. but it’s Google’s own and they’re making it open source without having to ask permission to anyone (well, for now, in the future expect a shit-load of IP-related lawsuits on this, especially since Sun and Microsoft signed a cross-IP licensing agreement on exactly such virtual machines technologies years ago

[...]

Android uses the syntax of the Java platform (the Java “language”, if you wish, which is enough to make java programmers feel at home and IDEs to support the editing smoothly) and the java SE class library but not the Java bytecode or the Java virtual machine to execute it on the phone. [...]

The trick is that Google doesn’t claim that Android is a Java platform, although it can run some programs written with the Java language and against some derived version of the Java class library. Sun could prevent this if they had a patent on the standard class library, but they don’t and, even if they did, I strongly doubt it would be enforceable since Android doesn’t claim to be compatible (and in fact, could very well claim that their subset/superset is an innovation on the existing patent and challenge Sun’s position).

[...]

Not only this allows Google to avoid having to battle thru the JCP for any change to the Java ME “standard” or tolerate Sun’s unique ability to veto any JCP change, but gives users a much more ‘fresh’ and modern class library to play with and built-in hooks to all the hardware features of your phone, including things like OpenGL, bluetooth, USB and all those things, which don’t come with the standard Java ME and therefore cannot be taken for granted by the developers.
