The Youtube video editor is a Testube app ( means it is beta), that lets you edit uploaded videos. I will run through some of the features of this editor.
Editing and Cropping Clips
Youtube / Google has really simplified this process.
First Just drag the Clip to the bottom video bar.
Next just select the Scissors on the Clip in the bottom video bar if you want to crop it
After that, You drag the sliders to the part of the video you want. Then you click save.
Enough Video Editing ... Now Music
Here you can not add music from your collection, but from youtubes. Youtube a huge collection of titles that has the right to use (legally).
Just click the plus button to add the song or drag it to the music bar.
Just add a title and click Publish
This video editor is a good video editor for the Cloud. By no means is this Pro or anything, but for the casual user of youtube it is a match made in heaven. I hope youtube pulls this out of the TestTube and in to youtube editing arsenal.
This is the video I made while making this review

Even been to a website that loads sluggish or not at all, one solutions is your MTU settings. Default it is set to 1500, but slightly adjusting this number will help significantly. This is pretty simple, but a little time consuming. This is how it is done.
Step 1: Finding your Setting
1a Use thsudois command to set a MTU setting.
Copy and Paste into Terminal: sudo ifconfig eth0 mtu 1492
I started with the setting 1492.
1b Next you ping, preferably a ISP ( They do not block ICMP). My time on 1492 was slow so I steped down. My number was 1472
Numbers you should use: 1492, 1484, 1472, 1468, 1460
Step 2: Set MTU Setting Permanent
2a Edit the following directory: /etc/network/interface
Use this Command: sudo gedit /etc/network/interfaces
and enter your password
2b What you need now is the following:
mtu (your preferred setting) --My Config: mtu 1472--
Next Click Save
2b Run the following command to restart your Network:
sudo /etc/init.d/networking restart
Step 3: Were did I get this?
3a Check Out this Blog: TTC Shelbyville Blog
Step 4: There is no Step 4
Kudos to anyone who got that...
