http://dutchephemeris.com/2011/12/03/the-dutch-ephemeris-very-first-blog
The Dutch Ephemeris’ very first blog. DutchEphemeris.com is your site for astronomical software. It focuses on celestial mechanics and its first software is a Java implementation of a fast and accurate planetary ephemeris. The Dutch Ephemeris is an open source library. You can download a package that contains all information, the source and of course the library itself. Starting today this site is created with WordPress. December 3rd, 2011.

Unit testing binary data
http://dutchephemeris.com/2012/01/03/unit-testing-binary-data
Unit testing binary data. The Dutch Ephemeris uses a binary version of the VSOP data. The main advantage of binary data is the reduced footprint, the resulting binary data is typically three times smaller than the original textual data. But how to test this? To check the content of the data you need to have a reader and some interpretation logic. That would mean writing a lot of software before you write a test and that is not what you want. The test goes like this:. T is created to test.

Going TDD
http://dutchephemeris.com/2011/12/04/going-tdd
Recently I followed a course given by Ron Jeffries and Chet Hendrickson. Together with about 20 colleague’s from Qualogy. We learned to use Test Driven Development in a better way. I was already convinced that TDD was the way to go and this course reaffirmed this strongly. Yes, I know, TDD speeds things up, but I also have my daily job. December 4th, 2011.

Monthly Archives: December 2012. Initially the Dutch Ephemeris was based on the VSOP87 theory from the. Therefore, I decided to switch to the DE406 theory from. This theory covers the time range from -3000 to 3000 and has almost the same accuracy as DE405. The differences are measured in metres…. December 6th, 2012. Unit testing binary data.
