In Linux, issue this command

$ convert -thumbnail 200 INPUT_FILE.png OUTPUT_FILE.png

To convert into another image type, just change the output file extension — as simple as that!

$ convert -thumbnail 200 INPUT_FILE.png OUTPUT_FILE.jpg

I have set up svn repositories on dedicated Linux server of my clients but the constant typing of svn password everytime I access the repository makes life for a developer less livable. Until I found the solution…

So here it is, follow the step and hurray!

1. Generate an SSH key pair of your Linux workstation so that you can set up automatic authentication (no more password asking). If you’ve already generated a DSA key pair, skip to step 2. Open a Terminal window. (On OS X, you can find this in /Applications/Utilities/Terminal)

   ssh-keygen -b 1024 -t dsa

   Do not enter a passphrase. Hit enter when prompted for one.

2. Execute the following to display your public key:

   cat ~/.ssh/id_dsa.pub

   Copy the output to the clipboard.

3. Log into your Server’s account’s shell via SSH. Once you’re logged in, execute

   cd .ssh

   If the directory doesn’t exist, create it:

   mkdir .ssh

   cd .ssh

4. Execute the command

   vi ~/.ssh/authorized_keys

   Hit i to enter Insert mode and then paste your public key (if there is already a key in this file, move to the bottom before pasting). Hit the ESC key to leave Insert mode and type :wq and hit enter to save and exit vi.

That’s it, no more password typing while doing your svn stuff.  Go ahead and try your svn commands.
