To ARC or not to ARC? What are the pros and cons? [closed]
...VC naming to make decisions about memory management. If it's all ARC code, then it doesn't matter because it will do it the same "wrong" on both sides. But if it's mixed ARC/non-ARC then there's a mismatch.
ARC will leak memory during ObjC exception throws. An ObjC exception should be very close in ...
how do I initialize a float to its max/min value?
...
@Faken: Even then you can define a comparison function that treats zero as the largest possible value, so you can still use std::min_element: bool less_ignoring_zero(unsigned a, unsigned b) { if (a == 0) return false; if (b == 0) return t...
Views vs Components in Ember.js
...C. But if you wanted to define your own application-specific HTML tags and then implement their behavior using JavaScript? You can't do this actually with a Ember.View.
Ember.Component
That's exactly what components let you do. In fact, it's such a good idea that the W3C is currently working on the ...
Does functional programming replace GoF design patterns?
...you have to wrap up the function in a class, which you can instantiate and then pass that object to the other function. The effect is the same, but in OOP it's called a design pattern, and it takes a whole lot more code.
And what is the abstract factory pattern, if not currying? Pass parameters to a...
What is dynamic programming? [closed]
... such as the string edit problem. You solve a subset(s) of the problem and then use that information to solve the more difficult original problem.
With dynamic programming, you store your results in some sort of table generally. When you need the answer to a problem, you reference the table and see...
Split a module across several files
...is solution, but this is much simpler: just do each thing in its own file, then use the "include!" macro in mod.rs:
include!("math/Matrix.rs");
include!("math/Vector.rs");
include!("math/Complex.rs");
That way you get no added nested modules, and avoid complicated export and rewrite rules.
Simple...
Can JSON start with “[”?
...guages, this is realized as an
array, vector, list, or sequence.
It then goes on to describe the two structures as:
Note that the starting and ending characters are curly brackets and square brackets respectively.

Is it possible to specify your own distance function using scikit-learn K-Means Clustering?
...
1) for cosine distance, first normalize all the data vectors to |X| = 1; then
cosinedistance( X, Y ) = 1 - X . Y = Euclidean distance |X - Y|^2 / 2
is fast. For bit vectors, keep the norms separately from the vectors
instead of expanding out to floats
(although some programs may expand for you)...
