I just upgraded to 9.04.

I have got to say that this is the most solid and polished Ubuntu yet. It Rocks!
No mayor new features as development was concentrated on stability, reliability and speed. They delivered!

Upgrade went without issues at all. Even my nvidia dual head setup that was always a problem with upgrades was handled perfectly.

Zero problems!

Upgrade took 1.5 hours TOTAL, using the Costa Rica mirror. With the MIT mirror it would have taken 13 hours.

HIGHLY recommended!

This is a nice way of keeping your secured passwords synced in all your computers and laptops, even cross-platform. Colin has a nice summary:

Tell me if this sounds like you: you have a few standard passwords that you routinely use for every site you visit. One of them you use for sites that don’t contain too much personal or sensitive information, and maybe you use one or two for sites that do. If you want to be REALLY secure you have another password that you only use for bank or credit card sites that contain your most sensitive information.

This is what I used to do (for many years in fact). Then I got to thinking: what happens if someone discovers one of those passwords? If it were one of the more sensitive ones, I’d be in deep trouble. So, I set out looking for a better way to manage my passwords.

What I’m going to describe in this article is a system I’ve implemented to manage my passwords in a secure, cross-platform way. It’s by no means the best way to do things for everyone, but it’s worked out extremely well for me thus far.

At the Linux Collaboration Summit in San Francisco, Intel Open Source
Technology Center director Imhad Sousou discussed the company’s plans
for the next major version of its Linux-based open source Moblin
platform. The aim of Moblin, Sousou says, is to improve the quality of
the Linux user experience on Atom-based devices. For Intel, this is a
broad mandate that reaches deep into the platform and will require
improvements at many different layers of the stack. One especially
important aspect of Intel’s platform improvement agenda is to reduce
overall startup time.

Tests of the latest Moblin 2 alpha release show that the major components of the stack, including the graphics system, can start up in mere seconds. Intel intends to build on this effort and hopes to eventually reduce total startup time to two seconds. Achieving this ambitious goal while still retaining the full software stack will be an important step for making Moblin an appropriate platform for embedded car computers and many other embedded applications where the software needs to be seamless and instantly accessible. “We think that two second boot is possible,” Sousou declared during his presentation.

The VNC client bundled with Ubuntu, Vinagre, works half the time. Fortunately, we can also VNC with the installed “Terminal Server Client”

The “VNC” option with the default installation of Terminal Server Client is disabled or grayed-out.

To enable it you need to install the xtightvncviewer package in Synaptic or with the following command on the terminal

sudo apt-get install xtightvncviewer

Done!

UPDATE: To also enable the XDMCP protocol option, sudo apt-get install xnest
