The Difference Between Android and iPhone

For someone who love to do something (‘ngoprex’) with his/her device and operating system, I think this article is definitely good for you. And this is the strip of hilarious satirical illustration sums up the difference between Android and iPhone.

Trying to install Android on Ubuntu 8.10

I’ve got this link and trying to install Android on my Ubuntu 8.10. But I’ve got some errors:

E: Unable to fetch some archives, maybe run apt-get update or try with –fix-missing?

It means that my repo doesn’t have those packages to be installed. Then I find another repo (http://ftp.csie.ncu.edu.tw/Linux/Ubuntu). I replace my old repo with this repo.

The next step is just follow these step:

1. root@abdusy-desktop:~/Documents# apt-get install openjdk-6-jre
If you find message like this:

Reading package lists… Done
Building dependency tree
Reading state information… Done
openjdk-6-jre is already the newest version.
You might want to run `apt-get -f install’ to correct these:
The following packages have unmet dependencies:
openjdk-6-jre-headless: Depends: ca-certificates-java but it is not installable
Depends: tzdata-java but it is not installable
Depends: rhino but it is not installable
E: Unmet dependencies. Try ‘apt-get -f install’ with no packages (or specify a solution).

2. Then run this step:
root@abdusy-desktop:~/Documents# apt-get -f install

Reading package lists… Done
Building dependency tree
Reading state information… Done
Correcting dependencies… Done
The following packages were automatically installed and are no longer required:
ttf-wqy-zenhei comerr-dev ttf-kannada-fonts libboost-thread1.34.1 libaccess-bridge-java libkrb5-dev libboost-date-time1.34.1 libldap2-dev
ttf-telugu-fonts libswfdec-0.8-0 libkadm55 ttf-oriya-fonts ttf-bengali-fonts libidn11-dev
Use ‘apt-get autoremove’ to remove them.
The following packages will be REMOVED:
openjdk-6-jre openjdk-6-jre-headless openjdk-6-jre-lib
0 upgraded, 0 newly installed, 3 to remove and 0 not upgraded.
3 not fully installed or removed.
After this operation, 85.2MB disk space will be freed.
Do you want to continue [Y/n]? Y

It’s done? No…We just begun for 1st step. The next steps is very clear in this link.
