After an unclean shutdown of my new AspireOne, the gnome NetworkManager under linpus doesn’t show up, it was very fustrating that both wireless and wired network doesn’t work anymore. It turns out to be the connection profiles have been corrupted, to fix this just simply delete the connection profiles under the home directory:
rm -rf $HOME/.gconf/system/networking/connections

JNI issues on linux
Problem #1: when compiling JNI component on a linux machine, it was missing tons of type definitions from jni.h. It appears libgcj-devel-version needs to be installed as the jni.h in it has the native datatype definitions.
Problem #2: if you see an error message such as the following when executing JNI components:
wrong ELF class: ELFCLASS64 (Possible cause: architecture word width mismatch)
Chances are that your jni shared library .so was compiled to be 64bit but your JDK/JVM is 32-bit! just use 64-bit java to run it instead
