Everything is a Puzzle waiting to be solved!
This is how my desktop looks like. I am running Ubuntu Gutsy Gibbon (7.10) and Gnome platform. I have been using Ubuntu for 3 years now and it is my all-time favourite operating system. It is easy to install, user-friendly, looks good, is fast and has almost everything that I need for my day to day work.
I bought my laptop (HP Pavilion dv9502AU Portable) around 3 months ago and I guess it is the right time to write up a quick review.
Overall I am very happy with this laptop. It suits my needs very well and I am very satisfied with it. The price (50K INR) is also a bargain for a 17 inch laptop in India. I bought this laptop from the Croma store in Malad.
This laptop has many good features (that is after all why I settled for it in the first place). Almost all of the laptop’s “basic” features get a pass grade easily. The processing power (1.8 GHz, 2 x 512 KB L2 Cache) and RAM (1 GB) allow Windows Vista to run reasonably well (though an extra gig of RAM would help significantly) and anything other than Vista (say Windows XP, Ubuntu Linux) runs like a breeze. The 8-cell battery consistently lasts for more than 3 hours and takes around 90 minutes to recharge fully after being fully drained. The laptop’s looks are decent enough but nothing stunning. The laptop also has all the bells and whistles expected from a modern machine (CD/DVD reader/writer, Ethernet card, modem, 5-in-1 card reader, WiFi 802.11 a/b/g, Bluetooth, ExpressCard slot, all kinds of slots, VGA webcam, microphones etc.) and till now I have not felt anything amiss. The laptop weighs a respectable 4 Kg, though this is pretty heavy if you have to lug around your machine a lot. Continue reading ‘Review - HP Pavilion dv9502AU Portable’
How do you get a new Ubuntu (or Debian or any distro using dpkg) installation to quickly have a specific set of packages installed without scouring through the list of packages and selecting packages one by one? More specifically how do you get a new Ubuntu installation (the target system) to have the same packages as your current one (the source system)?
Solution
Step 1: Configure and enable one or more repositories on the target system so that all repositories available in the source system are available in the target system. This Ubuntu help article - Adding Repositories in Ubuntu” - has more info on how to do it. Remember to add any non-standard repositories (for e.g. Google repositories) in addition to the standard ones.
Step 2: Get a listing of the packages currently installed on the source system using the following command.
sudo dpkg --get-selections | cut -f1 > installed-packages.txt
Step 3: Use the following command to feed the list of packages into apt-get on the target system, wait for apt-get to download and install all the packages and voila! you are done.
cat installed-packages.txt | sudo xargs apt-get install
