GeoJSON is a geospatial data interchange format based on JavaScript Object Notation (JSON). It defines several types of JSON objects and the manner in which they are combined to represent data about geographic features, their properties, and their spatial extents. GeoJSON uses a geographic coordinate reference system, World Geodetic System 1984, and units of decimal degrees.

Over the past two months, I’ve run what I consider an interesting experiment with my Twitter and Google+ followers: I’ve asked them what their favorite iPad apps were, and noted down the results.

The Emacs editor requires a lot of Lisp code and program state before it can start doing its job. That led Emacs developers to add the "unexec" feature to quickly load all of that at startup, but unexec has always been something of a hack. It employs a fairly ugly (and intrusive) mechanism to do its job. Some non-standard extensions to the GNU C library (Glibc) are required, so a plan to eventually eliminate those extensions was met with some dismay in the Emacs community.

Open a terminal window on your computer—whether Windows, Mac or Linux—and unless you’ve fiddled the defaults, the width is almost always 80 columns.

One of the most impressive hacks I've ever read about has to be the Black Sunday kill. Since the original 2001 Slashdot article I read on this [http://slashdot.org/articles/01/01/25/1343218.shtml] is 99.9% quote, I'm going to do the same. I can see why
