Connecting to Amazon's EC2 machines via SSH using the machine's name

I've written a cool bash tool to help me easily connect to my EC2 instances called Sash.

Going paperless - using Evernote

Now you should have a folder of scanned documents, backed up securely. It's time to meet my new best friend - Evernote.
Evernote is a cloud-based platform for note taking and archiving. Each note can contain attachments, be assigned to a notebook, and be tagged with multiple tags. It can then be searched for and retrieved.
Evernote has excellent support for PDF and image attachments, and has a built-in OCR engine for image attachments.

Going Paperless - backing up

After you have scanned all of your documents, your computer contains a large part of your life's paper trail.
When it was paper, you thought very little about backing it up - making copies of it, storing it off site, etc. Now, as digital data, you should consider changing that attitude.

Going Paperless

A couple of months ago, my wife and I took upon ourselves to move our paper clutter to the computer. We have accumulated over the past decade and a half all sorts of documents, which we annually or semi-annually go over, throw 30%, 'sort' 30%, and the rest stays jumbled till next time.

Creating Isolines (Contours) from grid data - part II

In my previous post I've described how you can take grid data and turn it into contour data. In this post I'll show how I implemented this using C#.

Creating Isolines (Contours) from grid data - part I

Since this is my first post, I thought I'd start with something I could not find anywhere on the net - an algorithm for taking gridded data (for example, in GRIB format), and turn it into contour line vectors.
I needed this type of algorithm when I wanted to add a meteorological layer to our GIS application. After some digging, I found some data sources I could use to get current wind speed and direction, waves height, and barometric data.
