Convert mp4 to mpg

Use ffmpeg

ffmpeg -i strong.mp4 -ab 56 -ar 22050 -b 200 str.mpg

See explanation of the parameters in the post http://kheyali.blogspot.com/2010/05/convert-flv-to-mpg-using-ffmpeg.html

But this gives a blocky ouput. To finely control the quality of the output use -qscale option. -qscale 1 gives best image quality 2 ,3 ... are progressively worse but generate files of smaller size. It is all a size and quality balancing game.

ffmpeg -i strong.mp4 -ab 56 -ar 22050 -qscale 6 str6.mpg

Fastest way to send multiple drafts from gmail

People claim that the fastest way to send multiple email drafts is to use Gmail IMAP with email client like Outlook or Evolution or Thunderbird. But I have found this is not true. Because Thunderbird and Evolution etc. email clients treats the drafts as emails still to be edited. So it is not just simple select all and hit send. Each email draft has to be opened and sent separately. That is a lot of clicks and mouse movements, wasting precious time and energy. I have a better solution which involves minimum keystrokes and mouse usage. Efficiency booster technique for sending emails. If someone is feeling adventurous and want to try it from the Gmail interface itself, here's how to do it in the fastest possible manner. It involves using the mouse once. Select the first draft. Gmail would open a new email box and put the cursor inside the box to write. Press TAB once to go the Send button. Press ENTER to send. Now Gmail sends it and the box is gone but the highlight goes to the last...

Changing the font size of section headings in LaTex
