netboot.me is a service that allows you to boot nearly any operating system or utility on any computer with a wired internet connection - without having to know ahead of time what you'll want to boot. Once you can netboot.me, you never need to update your boot disk again! In order for your computer to know where to find the netboot servers, you need to change your DHCP settings to return some extra information. The two relevant pieces of information: next-server, which should be "tftp.netboot.me", and "filename", which should be "netbootme.kpxe". How to set these settings depends on your DHCP server. For dhcpd, simply add the following to the relevant 'subnet' section of your configuration: next-server "tftp.netboot.me" filename "netbootme.kpxe" For dnsmasq, the following line in /etc/dnsmasq.conf will achieve the same effect: dhcp-boot=netbootme.kpxe,tftp.netboot.me netboot.me works through the magic of netbooting. There are a number of ways to boot a computer with netboot.me. The simplest is to download a bootable image and burn it to a CD, USB memory stick, or floppy disk. Boot off it on any networked computer, and it will automatically fetch the latest boot options from netboot.me and let you choose from dozens of installation, recovery, testing, portable desktop and other tools. You can also start netboot.me from any computer running gPXE, or from any netbootable computer with some simple tweaks to your DHCP server.

"Changes the "Send Later" command (Ctrl+Shift+Return) in the message composition window, so that instead of merely copying the message into your Outbox so that it is sent the next time you go online or do "Send Unsent Messages", a dialog pops up which allows you to specify when the message will be sent. You can specify a specific time and date, or click "15 mins later", "30 mins later" or "2 hours later", or click "Passthrough to Send Later" to get the built-in Thunderbird "Send Later" functionality (i.e., copy to Outbox)."

Ubuntu comes with a LiveCD installer. You can run the operating system without changing or formatting your hard drive. I can say it's pretty awesome because there are other things you can do aside from installing the OS. I will tell you that it can even reset your windows administrator passwords.
