MSSQL's float type is equivalent to the 64-bit double type in .NET. (My original answer from 2011 said there could be a slight difference in mantissa, but I've tested this in 2020 a...
What's the difference between deadlock and livelock?
...k is a risk with
some algorithms that detect and
recover from deadlock. If more than
one process takes action, the deadlock
detection algorithm can be repeatedly
triggered. This can be avoided by

randomly or by priority) takes action.

Framework vs. Toolkit vs. Library [duplicate]
...trol to the client.
A framework embodies some abstract
design, with more behavior built in.
In order to use it you need to insert
your behavior into various places in

framework's code then calls your code

Why do we need tuples in Python (or any immutable data type)?
...f sets, or keys in dictionaries). Again, this afford optimization, but far more than just "substantial" (designing decent hash tables storing completely mutable objects is a nightmare -- either you take copies of everything as soon as you hash it, or the nightmare of checking whether the object's ha...

Google Guice vs. PicoContainer for Dependency Injection
...annotations, so you do not need Guice specific annotations in your code anymore. Spring also supports these standard annotations. The argument that the Guice guys use is that without a Guice annotation processor running, these shouldn't have an impact if you decide to use a different framework.
