Multiple user profiles for Google Chrome

Recently I wanted to set up multiple profiles in Google Chrome. One for my personal browsing and one for my work. This way I don’t need to sign in and out from my different google, twitter, flickr and facebook accounts.

There is no GUI for this and it involves running some command line but it’s not too hard.

You should run all commands on one line and make sure to change the paths to your user name and profile.

Windows 7 / Vista

First you make a copy of your current default profile. You can do it either in Windows Explorer on on the command line.

xcopy "C:UsersOlaAppDataLocalGoogleChromeUser DataDefault" "C:UsersOlaAppDataLocalGoogleChromeUser DataOla" /e /i /h

Then you reset your new profile

C:UsersOlaAppDataLocalGoogleChromeApplicationchrome.exe --user-data-dir="C:UsersOlaAppDataLocalGoogleChromeUser DataOla" -first-run

Then you create a new shortcut on your desktop to launch your new profile

C:UsersOlaAppDataLocalGoogleChromeApplicationchrome.exe --user-data-dir="C:UsersOlaAppDataLocalGoogleChromeUser DataOla"

Ubuntu 10.10 (Linux)

Copy default profile

cp -r /home/ola/.config/google-chrome/Default/ /home/ola/.config/google-chrome/Ola

Reset your new profile

/opt/google/chrome/google-chrome --user-data-dir="/home/ola/.config/google-chrome/Ola" -first-run

And add a new Launcher (shortcut)

/opt/google/chrome/google-chrome --user-data-dir="/home/ola/.config/google-chrome/Ola" -first-run

That’s all there is to it.


Firefox hides tabs and fails

I while ago I introduced a friend to Firefox. I didn’t want to push it but just show it and I hoped it would stick. After some weeks I asked if she liked it and she said it was nice but that she missed the tabs that IE had. I was amazed… Firefox were years before IE with tabs but still it fails… Look at the screen shot from Firefox 3. Nothing tells you the interface is tabbed.

Firefox fails to show how to open new tabs. Internet Explorer leads the way!

Luckily Firefox 3.5 seems to address the issue. Firefox 3.5 also makes it even clearer than Internet Explorer with a + in the new tab button. Way to go Firefox!

Easy way to convert videos using FFmpeg!

Update: I used FFmpeg for some conversions but I just found out Avidemux and it seems promising! Trying it right away!

Every once in a while I get my hands on a video file that I can’t play. Today when I wanted to watch a bouldering movie it failed. Not sure why. Maybe becuase my WLAN wasn’t fast enough to stream the huge HD file?

I looked around and found no nice tools to convert the movies. Either it was some shareware, adware or I just couldn’t find the download link on the ugly web site… I reverted and decided to try to use the command line tool FFmpeg to encode my videos to mpeg and be able to play them. It worked so good I’m amazed!

In Ubuntu FFmpeg is included in the distribution and is easy to install via Synaptic or Apt (sudo apt-get install ffmpeg). In Windows you can use this unofficial builds.

To make the conversion I used the following: ffmpeg -i OriginalVideo.mp4 -ab 128k -b 2000k EncodedVideo.mpg

Tip: If you are testing different settings for FFmpeg add -t 60 to encode only the first minute of the video.

FFmpeg is capable of creating videos with different codecs as well, but I didn’t need that currently so that will be a later exercise!
