jQuery Plugin – Image Radio buttons

12 Oct

At work I’ve written this jQuery plugin. It’s only 2KB big and turns your normal radio buttons into images, you can set any images you like for src, checked and hover. Simply attach the configuration to your html input field as the class attribute as a JavaScript like object. I know you might want to attach a class to your radio buttons, but this is how far it currently is.

Here an example:

Get the JavaScript code
Get the HTML/JavaScript code

Edit: Just found this which seems to make this plugin obsolete. Wish I would have found this earlier…

Ubuntu on Asus N53S(V)

08 Oct

To install Ubuntu with a working NVIDIA card on this laptop. Follow these instructions:

Follow https://help.ubuntu.com/community/Asus_N53
Add this to your modules blacklist in /etc/modprobe.d/blacklist.conf:
```
blacklist nouveau
blacklist fbcon
blacklist vga16fb
```
Run 3D Graphics intensive applications like Google Earth with
```
optirun google-earth
```

Optional: Mount Windows NTFS partition in /etc/fstab:

/dev/sda5       /d      ntfs    noexec,nosuid   0       0

Edit: You might not need to add the blacklist. I’ve just setup 11.04 64 bit and did not black list the drivers and it works! Remember to NOT enable the additional drivers in this setup because it will override your Intel Drivers, which are good because you can still run 3D apps but with less power consumption.

How to backup Windows XP/7 partition with Linux (Ubuntu)

23 Aug

To backup any partition of any file system type with Linux, you can simply run the following command:

dd if=<input_partition> of=&<output_file> bs=<byte_count>

where

<input_partition>:= is the partition you want to backup (this can also be a file if you want to do the reverse). So, e.g. /dev/sda1 for the first partition on the first drive (hence a=drive 1, 1=partition 1, b=drive 2, …).

<output_file> := is the file you want to write the partition to (this can also be the output partition on restore).

<byte_count> := is the size of your file system’s clusters, normally 4096.

dd if=/dev/sda2 of=/d/sda2_partition bs=4096 #for my own reference
tar cvfz sda2_partition.tar.gz sda2_partition # own reference

You can then compress the file using a normal archiver and save a lot of space that way, because dd constructs a file as big as the partition because it reads bit by bit or 4096 bytes multiple times.
