Google Chrome on Ubuntu (well, sort of) November 17, 2009
Posted by rsentana in : computer, internet, linux, open source , 1 comment so farMost of us already know that one of the fastest browser out there is Google Chrome. Sadly enough, Google Chrome is only available on Windows platform, while the Mac and Linux users are left to run Safari or Firefox. The good thing is that Google has listened to those requests and are currently developing the native version of Chrome to Mac and Linux.
But for those who can’t wait, there is a way to get Chromium (the open-source platform on which Google Chrome is based). Here are the steps (originally taken from here):
First you need to edit the /etc/apt/sources.list file:
sudo gedit /etc/apt/sources.list
Add add the following lines if you are using Ubuntu 9.10 (Karmic Koala):
deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntu karmic main
deb-src http://ppa.launchpad.net/chromium-daily/ppa/ubuntu karmic main
Save and exit the file.
Now add the GPG key using the following command:
sudo apt-key adv –recv-keys –keyserver keyserver.ubuntu.com 0xfbef0d696de1c72ba5a835fe5a9bf3bb4e5e17b5
Update the source list using the following command:
sudo apt-get update
Then you can install chromium using the following command:
sudo apt-get install chromium-browser
After a successful installation, you can open chromium from Applications—>Internet—>Chromium Web Browser:
Here’s a sample picture of what Chromium looks like on Ubuntu:
Alternatively, there’s a script created by Jeff Rader to automate the installation of Chromium. His script can be downloaded here. Do not forget to change the permission to executable before running the script.
Enjoy!

Run your own Ubuntu Enterprise Cloud, part 3 October 19, 2009

In part 1 and part 2 of this series, we saw how to set up a minimal cloud infrastructure and bundle a basic image (and test it). In this final article, we’ll play with our cloud from an end-user perspective.
Setting up the web UI
First of all, before accepting end users, as the administrator of the cloud you will have to setup a few things on the web UI. Using your favorite browser, you should:
* Open https://cloudcontroller:8443/
* Log in using the default user/password: admin/admin
* Change the default password, setup the cloud admin email address
* Logout
Setting up the cloud client
We’ll use Ubuntu 9.10 beta for this purpose, as it includes all the needed packages, and it’s so great ! You will have to install the following packages:
$ sudo apt-get install euca2ools unzip
Registering on UEC, getting credentials
As the end-user, fire up your favorite browser and:
* Open https://cloudcontroller:8443/
* Click “Apply” and enter your end user details
If you set up the email correctly on your cloud controller, it should send an email to the cloud admin address asking him to approve that request. Follow the instructions on that email to approve the account as the admin.
You should then get an email at the end user email address asking you to confirm the account request. Follow the instructions on that email, then you can log in on the web UI:
* Open https://cloudcontroller:8443/
* Login using your end user username and password
* Click “Download Credentials” in the “Credentials” tab
* Note the EMI reference you can use on the “Images” tab
Starting up an instance
You should unzip the credentials zipfile you just downloaded, then source the eucarc file and test the connection:
$ unzip euca2-enduser-x509.zip
$ . eucarc
$ euca-describe-availability-zones verbose
Setup a SSH key and allow connection to the SSH port:
$ euca-add-keypair enduserkey > enduserkey.priv
$ chmod 0600 enduserkey.priv
$ euca-authorize default -P tcp -p 22 -s 0.0.0.0/0
Then starting up an instance is just a matter of passing the right EMI and type:
$ euca-run-instances -k enduserkey emi-XXXXXXXX -t c1.medium
Enjoy !
