General suggestions for debugging in R
...g is to reproduce the problem...if you can't do that, then you need to get more information (e.g. with logging). Once you can reproduce it, you need to reduce it down to the source.
Rather than a "trick", I would say that I have a favorite debugging routine:
When an error occurs, the first thi...
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
the framework either by subclassing or
by plugging in your own classes. The
framework's code then calls your code

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
ensuring that only one process (chosen
randomly or by priority) takes action.

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.

What does Docker add to lxc-tools (the userspace LXC tools)?

How do I concatenate two arrays in C#?
... @manthrax -> In its defense, C# tends to favor lists which are much more powerful than arrays. It seems the only functional purpose for using arrays is for Interop calls (Unmanaged C++).
