Ubuntu Server ships with a few expensive (memory, CPU, disk) periodic processes which are quite unneeded and suck up precious resources on Amazon EC2:
apt-get remove landscape-client apt-get remove consolekit apt-get remove update-motd apt-get remove update-notifier-common apt-get autoremove Reclaimed 20% of my RAM right away - also, CPU and swap usage dropped like a stone. What are these? They run periodically to notify you of package updates (you should know how to do this yourself) and update the /etc/motd file whenever someone logs in.
Ubuntu 11.04’s new menubar is a user interface disaster. Here’s one way I’ve found to turn it off:
echo 'unset UBUNTU\_MENUPROXY' >> /etc/X11/Xsession.d/81noappmenu You can also probably remove /etc/X11/Xsession.d/80appmenu, but a package update will put it back.

After a hiatus and some neglect I’ve put some love back into the screenshot gallery - now hooked up to facebook (maybe twitter soon) so friends can see. For those unfamiliar, what’s the point? Everyone’s got a favorite new computer, phone, wallpaper, widget, app or Internet moment they’d sometimes like to share, so why not share it.

Skype has lots of users, especially in the business world, but a lot of other folks seem to have strong opinions on it. Adverts, user interface design, bandwidth usage, privacy, the critiques seem to run the gamut. Seems to me its the only IM service with an official client that actually looks like a Windows application without sporting an atrocious looking window style. The buddy list also has only one ad right at the bottom, and even then its not there all the time.
Played with Unity, the new desktop shell in Ubuntu. It places a notification bar along the top of the screen from left to right, and an application dock / taskbar down the left side of the screen. Clever looking on first boot. Some thoughts:
In almost all apps, the menu bar is hidden by default, but there are seldom sufficient controls exposed by the application to justify this - the menu bar is required for a great deal of the functionality in various Linux applications which is not exposed by the default toolbar buttons.
With the introduction of Amazon EC2 micro instances I’ve decided to move my personal server from Burst.NET into an EC2 instance. Huzzah! Amazon provides a rather interesting service with EC2, giving an account holder the ability to spawn numerous virtual machines on demand for experimentation, deployment and migration purposes. Impressed!
A good talk by Eben Moglen on the implications things like Facebook have on our privacy and personal security. Particularly interesting This speech was made before Facebook newly updated its privacy policies and extended its reach to sharing your personal information with almost every major media outlet online. Worth a watch - skip ahead to 2:05, that’s where he begins to speak.
