Serializing an object as UTF-8 XML in .NET
...into a string again, so its no longer in UTF-8, but back in UTF-16 (though ideally its best to consider strings at a higher level than any encoding, except when forced to do so).
To get the actual UTF-8 octets you could use:
var serializer = new XmlSerializer(typeof(SomeSerializableObject));

Too many 'if' statements?
...
Other people have already suggested my initial idea, the matrix method, but in addition to consolidating the if statements you can avoid some of what you have by making sure the arguments supplied are in the expected range and by using in-place returns (some coding standa...
Must Dependency Injection come at the expense of Encapsulation?
...OOP concepts. Admittedly we're using an OO language as the 'host', but the ideas behind IoC come from component-oriented software engineering, not OO.
Component software is all about managing dependencies - an example in common use is .NET's Assembly mechanism. Each assembly publishes the list of a...
Python - write() versus writelines() and concatenated strings
...e a string for a newline in write() but I can use it in writelines()?
The idea is the following: if you want to write a single string you can do this with write(). If you have a sequence of strings you can write them all using writelines().
write(arg) expects a string as argument and writes it to ...

Why doesn't the JVM cache JIT compiled code?
...d in the JVM implementation, but I can think of some plausible ones:
The idea of Java is to be a write-once-run-anywhere language, and putting precompiled stuff into the class file is kind of violating that (only "kind of" because of course the actual byte code would still be there)
It would incre...
How to get the difference between two arrays of objects in JavaScript
...
I take a slightly more general-purpose approach, although similar in ideas to the approaches of both @Cerbrus and @Kasper Moerch. I create a function that accepts a predicate to determine if two objects are equal (here we ignore the $$hashKey property, but it could be anything) and return a ...
How does Bluebird's util.toFastProperties function make an object's properties “fast”?
...htly outdated article is still a fairly good read that can give you a good idea on how objects are stored in v8.
Why it's faster
In JavaScript prototypes typically store functions shared among many instances and rarely change a lot dynamically. For this reason it is very desirable to have them in f...
