mikehadlow / IBus.cs
Created November 15, 2013 14:49
EasyNetQ's proposed new send/receive API. This is for sending messages explicitly to a named destination queue via the default exchange. The Receive call creates a consumer for the specified message type. Further calls to Receive with the same queue, but a different message type will add additional message handlers to the same consumer.
/// <summary>
/// Send a message directly to a queue
/// </summary>
/// <typeparam name="T">The type of message to send</typeparam>
/// <param name="queue">The queue to send to</param>
/// <param name="message">The message</param>
void Send<T>(string queue, T message);
/// <summary>
/// Receive messages from a queue.

mikehadlow / Astrology Smackdown
Created October 15, 2013 15:27
Somebody in the office was defending astrology. Their argument went something like this: You concede that the Moon is known to effect natural phenomena on Earth. Jupiter is a far larger body, although granted it is further away, so it must have some effect as well.
Newton's law of universal gravitation:
http://en.wikipedia.org/wiki/Newton%27s_law_of_universal_gravitation
F = G(m1 * m2)/r^2
Mass of the Earth: 5.97219 × 10^24 kg
Mass of the Moon: 7.3477 × 10^22 kg
Distance to the Moon (average): 384,400 km
