Considerations on configuring my GitHub account on a new Ubuntu install


I changed laptops and I needed to reconfigure my GitHub account.

At first, I wanted to reuse the SSH key that I used on my other computer, which works fine. Afterwards, I changed my mind as it is actually less hassle to generate a new key and to add it to my GitHub account. Once the new laptop was configured, I could remove the former key.

In any case, I first needed to install an SSH client in order to follow the setup guide from GitHub. I installed OpenSSH with the following command:

$ sudo apt-get install openssh-client

Then I could follow the procedure to generate a new key pair and configure my account.

If I had wanted to reuse my existing key and passphrase, I could have copied the following two files from my current computer to the ~/.ssh folder of the target computer.

  • ~/.ssh/id_rsa
  • ~/.ssh/id_rsa_pub

Switching SD Cards on an Android Phone


I decided to substitute the default 4GB micro SD card provided with my HTC Desire with a 16GB one. Here is a summary of how I did it. It’s extremely simple actually 🙂 I haven’t tried on any other phone but I take for granted that I shall work with other Android phones.

  1. Copy the contents of the current card to your hard drive.
  2. Copy the contents from the hard drive to the new card.
  3. Replace the current card with the new one.

As the contents of the card was the same after the substitution, I was surprised to find that WinAmp could not find back the covers of the albums in my music library. Except that, the substitution went without a hitch.

To copy the contents of the current card to the hard drive, I use a card reader. I could have plugged in the phone and copy directly from it as well.
