Change the cache location for Chromium

Update: You can create tmpfs and mount it to the default cache folder of Chrome / Chromium.
google-chrome /home/jerry/.cache/google-chrome tmpfs defaults,noatime,mode=1777 0 0

If you have plenty of memory and want to move some temporary files out of your disk, tmpfs is the answer. Especially when you are using an SSD and don't want to wear it out soon.

I already did so for Firefox and PostgreSQL, and it's time for my Chromium (or Google Chrome) for Ubuntu.

Create a launcher. In the Launcher Properties, keep the Type to be Application, set the Name to "Chromium Web Brower" and Comment to "Access the Internet". Set Command to be "/usr/bin/chromium-browser --disk-cache-dir=/tmp --disk-cache-size=134217728 %U". That's it.

Note that
  • there are no quotation marks (") for the value of disk-cache-dir
  • path in disk-cache-dir is relative to your home, if it's not an absolute path
  • the unit of disk-cache-size is byte

When Evolution meets Microsoft Exchange

I tried to use Evolution (since it's the default email client in Ubuntu distro) to access Microsoft Exchange Server but failed. In Evolution Account Assistant, after I set Server Type to Microsoft Exchange and provide OWA URL in Receiving Email dialog box, I always got
Could not authenticate to Server.
Make sure the username and password are correct and try again.
Let me know if you have any idea about what's going wrong, but I decided to try something else.

sudo apt-get install evolution-mapi

This will also install libexchangemapi-1.0-0, which evolution-mapi depends on. Choose Exchange MAPI as Server Type and provide Server, Username and Domain name.

Upgraded to Ubuntu 10.10 Maverick Meerkat

update-manager --devel-release worked beautifully for me. The only issue I found is linux-image-2.6.32-25-generic is not removed by Update Manager, but it's a piece of cake for any Linux users.

I love the new font and Firefox's theme. Obviously they are designed with wide screen in mind, because I found there is more vertical space remained.

Well done, Canonical.
