Mipony: javascript is required

When MiPony says "javascript is required" in Captcha window, on Windows just add the target site (say uploaded.net) to the Trusted Zone in Internet Explorer options.

Ok, this one is a long story. Frequently we need to search in a collection of objects. Typical solution is to store the collection not as List<Person> (because searching by Person.Name in a List<Person> will be O(N) operation), but as a Dictionary<string, Person> where key represents the name. Searching in this collection will be a O(log(N)) operation what is much better. The problem here is that if we want to search by name and last name we are forced to maintain 2 different Dictionary<string, Person>, one for the Name and second for the Last Name. But now there is something we can do about that.
