Major update of X-Ray Attenuation Calculator

I just updated the X-Ray Attenuation Calculator, to also include the NIST database of compounds. Besides, the graph engine has been update to the latest achartengine, which was published a few days ago. This version of achartengine should be compatible with android 1.5 and 1.6 again, so if requested I will change the app to be available for those android versions too.

Archos Gen8 kernel with iptables and ext4

The Archos 70Sit is a very nice and cheap Android tablet. However, it can do with some improvements. If you want te have

• the latest stock firmware
• root access
• 1GB ext4 data partition
• iptables support for Droidwall

then you better read further!
 
Thanks to the great work done by recognized XDA devs as chrulri and $aur0n I now managed to compile my own kernel for stock Archos Gen8, with support for iptables (so Droidwall can be used) and ext4 (so a 1GB ext4 /data partition can be made on internal sd card).

If you want to enhance your Archos with these features, head over to my xda-forum post.
