In Python, how do I determine if an object is iterable?
...n understanding of what happens when you employ a for loop in Python. Feel free to skip right to the next section if you already know.
When you use for item in o for some iterable object o, Python calls iter(o) and expects an iterator object as the return value. An iterator is any object which impl...
What are the most interesting equivalences arising from the Curry-Howard Isomorphism?
... the inclusive variety. I think this holds as a proof, but feel more than free to disabuse me of this notion.
Similarly, your definitions for tautology and absurdity as the identity function and non-terminating functions, respectively, are a bit off. The true formula is represented by the unit typ...
Virtual Memory Usage from Java under Linux, too much memory used
...this to make the VM less aggressive about growing the heap:
-XX:MinHeapFreeRatio=40 Minimum percentage of heap free after GC to
avoid expansion.
Also, from what I recall from experimenting with this a few years ago, the number of native libraries loaded had a huge impact on the minimum footp...
How does Java handle integer underflows and overflows and how would you check for it?
... preventing and detecting integer overflow. The standard is published as a freely accessible online resource here: The CERT Oracle Secure Coding Standard for Java
The standard's section that describes and contains practical examples of coding techniques for preventing or detecting integer overflow ...
Asking the user for input until they give a valid response
...tainly I release the code blocks that I wrote into the public domain. Feel free to use them in any context, without my explicit permission or knowledge. Regarding the non-code-block segments, If you want to paste my entire answer into a "Learn Python" book you're writing, let's talk royalties ;-)

In C#, What is a monad?
... null. This allows the code that we write using the monad to be
entirely free of this null-checking behaviour, we just use Bind and
get a variable bound to the value inside the monadic value (fval,
gval and hval in the example code) and we can use them safe in the
knowledge that Bind will t...

LINQ - Full Outer Join
...erf (node-based containers have more cost in principle, and hashing is not free and efficiency depends on the hash function/bucket spread), it will certainly be more algorithmically efficient. So, for small loads I'd expect it might not be quicker

Why all the Active Record hate? [closed]
...hinks it knows but doesn't, or tries to externalize concept work to ME for free, costs me many precious hours, days, weeks and months of my time, live is too short ... ).
So, finally: THIS ALL is why I hate that silly "active record pattern", and I do and will avoid it whenever possible.
EDIT: I w...
load and execute order of scripts
...n in an unpredictable order. The browser loads them in parallel and it is free to run them in whatever order it wants.
There is no predictable order among multiple async things. If one needed a predictable order, then it would have to be coded in by registering for load notifications from the asy...
