Haversine and Vincenty are two algorithms for solving different problems. Haversine computes the great circle distance on a sphere while Vincenty computes the shortest (geodesic) distance on the surface of an ellipsoid of revolution. So the answer to your question can be broken into 2 parts: Do you want to compute the distance on a … Read more
I’d try to keep it away from computers altogether. Ask your audience how they find an entry in a dictionary. (A normal dictionary of word definitions.) The naive implementation is to start at the very beginning, and look at the first word. Oh, that’s not the word we’re looking for – look at the next … Read more
The professors have the disadvantage that they can’t put you on huge, nasty programs that go on for years, being worked on by many different programmers. They have to use rather unconvincing toy examples and try to trick you into seeing the bigger picture. Essentially, they have to scare you into believing that when an … Read more
Ask them to write unit tests for the methods.
Have a look Simian, you can use it for Java, C#, C, C++, COBOL, Ruby, JSP, ASP, HTML, XML, Visual Basic, Groovy source code and even plain text files. Also, a similar question here.
There are various papers describing data structures and algorithms for this use case. In addition you can see the code or descriptions of open source implementation of crontab and of Quartz (Java) or Quartz.NET (.NET). This is one such paper http://portal.acm.org/citation.cfm?id=359763.359801&coll=ACM&dl=ACM&CFID=63647367&CFTOKEN=55814330 For example, cron stores the information like this (* means every, so a * … Read more
The File.Exists method exists primarily for testing for the existence of a file when you do not intend to open the file. For example testing for the existence of a locking file whose very existence tells you something but whose contents are immaterial. If you are going to open the file then you will need … Read more
Make methods static when they are not part of the instance. Don’t sweat the micro-optimisations. You might find you have lots of private methods that could be static but you always call from instance methods (or each other). In that case it doesn’t really matter that much. However, if you want to actually be able … Read more
This sounds over-simplistic, but I think it makes sense to simply use exceptions where they are appropriate. In languages like Java and Python, exceptions are very common, especially in certain situations. Exceptions are appropriate for the type of error you want to bubble up through a code path and force the developer to explicitly catch. … Read more
As some has pointed out in the comments, what you want to look into is PCM audio. In a nutshell, sound is a wave that travels through air. In order to capture that sound, we use a microphone, which contains a membrane which will vibrate as the sound waves hit it. This vibration is translated … Read more
