command line graphing: gnuplot
Who needs charts on the command line?
If you have ever been stuck at an ssh prompt staring a bunch of data gnuplot is a must have tool. I was looking at response times over an ssh prompt and realized how I missed MS Excel. All this data would make much more sense as a chart! Apparently there are others who would agree with me and that’s the reason gnuplot exists.
Enter gnuplot
gnuplot is a command line tool that generates complex plots from data. It has a lot of options and can generate the plots as PNG, SVG etc. But most importantly it can plot your data as an ASCII chart :).
Bonus points
I use gnuplot to check my nodejs logs:
tail —lines=1000 ~/.forever/*.log | grep ‘Time: ’ | sed ‘s/.* Time: l: //’ > data
gnuplot> set terminal dumb
gnuplot> plot “data”This is a static plot but you can even plot animated graphs like this:

Cloud9: IDE in the cloud
Cloud9 is a cloud based IDE that works completely within the browser. It even provides a full linux terminal within the browser. It is ideal to try out some open source language/framework quickly without doing the full setup.
Currently it supports nodejs, PHP, python and ruby out of the box. There are plans to support .Net in the future. It allows one-click deployment to cloud platforms like Azure, CloudFoundry and Heroku. PFB screenshot of my attempt at a simple nodejs program :).

@benguild: Leaked screenshots of native Google Maps (Alpha) for iOS 6. →
Oh boy! Here we go.
- It’s vector-based.
- It’s got two-finger rotation to any angle.
- It’s super fast.
- 4-inch height of the iPhone 5 is supported!
Here are some blurry photos. Ever since iOS 6 came out, we lost Google Maps. However, Google has been rumored to be hard at work on their own…

Download Youtube subscriptions on a schedule
My BSNL broadband plan gives me unlimited data between 2 AM and 8 AM. I thought this would be a great time to download all my YouTube subscriptions. I could watch the videos the next day without using my download quota!
I found a couple of great scripts to get the job done. I had to make a few changes to get them working on windows:
Prerequisites:
- Cygwin or another shell for windows.
- Python
Just run the subscriptions script like so:
./download-youtube-subscriptions.sh mandarlimaye
Put this command in a batch file and schedule it to run whenever you like.
