How do I replace the *first instance* of a string in .NET?
...gex.Replace(String, String, Int32), which can do the same, but is probably more expensive at runtime, since it's utilizing a full featured parser where my method does one find and three string concatenations.
EDIT2: If this is a common task, you might want to make the method an extension method:

...smaller amount.
So when do we finally "use" the 1? When there are only no more permutations of the last 3 digits.
And when are there no more permutations of the last 3 digits? When the last 3 digits are in descending order.
Aha! This is key to understanding the algorithm. We only change the positi...

...ary search on the values of the switch, which (in my mind) would be a much more useful optimization, as it does significantly increase performance in some scenarios, is as general as a switch is, and does not result in greater generated code size. But to see that, your test code would need a LOT mor...
When should I use Arrow functions in ECMAScript 6?
...ken off quite a bit. ES6 will also ship a Promise object, which means even more anonymous functions. There is no going back for functional programming. In functional JavaScript, arrow functions are preferable over regular functions.
Take for instance this (particularly confusing) piece of code3:

...So that can be beneficial too.
Specifically talking about fonts (and even more specifically, Google's offering), I would probably stick with a CSS method (I like @import because it keeps styling with the stylesheet, but that could be just me). The JS file loaded by the script (http://ajax.googleapi...

}.bind(this);

There is much more that could be said on this topic and many patterns that you could explore (like module pattern and revealing module pattern), but basically using a function gives you more flexibility and control over how the object gets...
Implementing comparison operators via 'tuple' and 'tie', a good idea?
...as, especially if they are both of the same type. This gets even worse for more than two members, as nesting pair s pretty much sucks.
The other option for that is a tuple , either from Boost or C++11, but that doesn't really look any nicer and clearer. So I go back to writing the structs myself...
