Savvy Graph

I guess everyone reading this post is somewhat familiar with amazon.com and may have done some shopping on it. It not very unlikely, that you may have searched for a product that has a ton of reviews and different ratings. I always felt that there should be a simpler way to make sense of all those reviews and ratings. Guess what ! Someone was thinking along similar lines and they actually a very neat and nifty tool called savvygraph.

Quoting from a article about savvygraph "Web site SavvyGraph displays the average rating and number of reviews for each on a simple graph to give you a quick method for comparing items on Amazon. The idea is that the higher the rating and number of ratings a product has, the better it's likely to be. So products garnering a place on the top right of the graph (high rating, high number of reviews) are the best buys. You can hover over push-pins to see which products are which, and the color of the pins indicate whether or not free Super Saver Shipping is available for that product through Amazon."

Visit http://www.savvygraph.com/ and see for yourself.

I liked the concept and feel its a useful enough tool to get a quick and dirty estimate about a particular product before pouring into reviews.

A small and stupid one liner for seeing the instantaneous bandwidth

Disclaimer: May or may not work for you. Use a bash shell or make necessary changes to support any other. There may be many other ways of doing this efficiently.

Usage :
- Edit the variables int and dir as desired.
- dir = RX will calculate download speed
dir = TX wil calculate upload speed.
- Cutpaste the one liner as is on a bash shell.

int="eth1"; dir="RX"; oldbytes=0; while [ 1 ]; do bytes=`ifconfig $int | grep "$dir bytes" | awk '{print $2}' | awk 'BEGIN {FS=":"} {print $2}'`; bw=`expr $bytes - $oldbytes`; bw=`expr $bw \* 8`; bw=`expr $bw / 1024`; oldbytes=$bytes; sleep 1; echo "$bw Kb/s"; done

Use of the above : Left to the readers imagination.
