What is the difference between LINQ ToDictionary and ToLookup
...ookup<,> interface.
As a side note, you can query a lookup (via the indexer) on a key that doesn't exist, and you'll get an empty sequence. Do the same with a dictionary and you'll get an exception.
So: how many records share each key?
An overly simplified way of looking at it is that a Loo...

Is it possible to use “/” in a filename?
...nstruct the name from the encoded version.
Another option is to create an index - create the output filename using whatever method you like - sequentially-numbered names, SHA1 hashes, whatever - then write a file with the generated filename/URL pair. You can save that into a hash and use it to do a...

Where can I get a “useful” C++ binary search algorithm?
... binary search functions are not useful in case where you want to know the index of the element you are looking for. I have to write my own recursive function for this task. I hope this, template<class T> int bindary_search(const T& item), should be added to the next version of C++.

what is the best way to convert a json formatted key value pair to ruby hash with symbol as key?
... in the symbolize_names option. See here: http://flori.github.com/json/doc/index.html (look under parse)
eg:

>> JSON.parse(s,:symbolize_names => true)
=> {:akey=>"one", :bkey=>"two"}

There's no problem in calling next() inside the callback.

Is there a printf converter to print in binary format?
...ers need to know how to properly use the standard library. Maybe using an indexed array for assignment would have been a good demonstration (and will actually work, since b isn't reset to all-zeros each time you call the function).
