Java 8 stream's .min() and .max(): why does this compile?
...
Let me explain what is happening here, because it isn't obvious!
First, Stream.max() accepts an instance of Comparator so that items in the stream can be compared against each other to find the minimum or maximum, in some optimal order that you don't need to worry too mu...
What are the downsides to using Dependency Injection? [closed]
...
A couple of points:
DI increases complexity, usually by increasing the number of classes since responsibilities are separated more, which is not always beneficial
Your code will be (somewhat) coupled to the dependency injection framework you use (or more generally ...
How can I pair socks from a pile efficiently?
...iring the socks from the clean laundry and figured out the way I was doing it is not very efficient. I was doing a naive search — picking one sock and "iterating" the pile in order to find its pair. This requires iterating over n/2 * n/4 = n 2 /8 socks on average.

What is the purpose of Flask's context stacks?
I've been using the request/application context for some time without fully understanding how it works or why it was designed the way it was. What is the purpose of the "stack" when it comes to the request or application context? Are these two separate stacks, or are they both part of one stack? Is ...
Should the folders in a solution match the namespace?
...o, note that if you use the built-in templates to add classes to a folder, it will by default be put in a namespace that reflects the folder hierarchy.
The classes will be easier to find and that alone should be reasons good enough.
The rules we follow are:
Project/assembly name is the same as t...

Scanner vs. StringTokenizer vs. String.Split
I just learned about Java's Scanner class and now I'm wondering how it compares/competes with the StringTokenizer and String.Split. I know that the StringTokenizer and String.Split only work on Strings, so why would I want to use the Scanner for a String? Is Scanner just intended to be one-stop-shop...
Do I need Content-Type: application/octet-stream for file download?
...
No.
The content-type should be whatever it is known to be, if you know it. application/octet-stream is defined as "arbitrary binary data" in RFC 2046, and there's a definite overlap here of it being appropriate for entities whose sole intended purpose is to be save...
Why do we need a pure virtual destructor in C++?
...the real reason that pure virtual destructors are allowed is that to prohibit them would mean adding another rule to the language and there's no need for this rule since no ill-effects can come from allowing a pure virtual destructor.
Nope, plain old virtual is enough.
