Nearest neighbors in high-dimensional data?
...ances (to calculate predicted values) for n=1, n=2, n=3, etc. and plot the error as a function of n. If you just want a plausible value for n to get started, again, just use n = 3.
The second component is how to weight the contribution of each of the neighbors (assuming n > 1).
The simplest wei...
MVVM in WPF - How to alert ViewModel of changes in Model… or should I?
...model itself - when you push data to your Model, it may cause
validation errors. The VM will then have to remap this information
back to the View.

Why not use always android:configChanges=“keyboardHidden|orientation”?
... rotated
In many cases, people mistakenly believe that when they have an error that is being generated by an orientation change ("rotation"), they can simply fix it by putting in android:configChanges="keyboardHidden|orientation".

std::function vs template
... as possible at compile-time. The rationale is simple: if you can catch an error, or a type mismatch, even before your program is generated, you won't ship a buggy program to your customer.
Moreover, as you correctly pointed out, calls to template functions are resolved statically (i.e. at compile...

Lock-free multi-threading is for real threading experts
...based solution can be easier to reason about, easier to implement and less error-prone than a half-baked locking implementation that tries to be smart. (It is however - subjectively - also true for an STM based solution.) I would also bet that it is light-years easier to correctly write a decent dis...
Referring to the null object in Python

It's my personal opinion that these messages could simply just mention None by name because, as we'll see shortly, None leaves little room to ambiguity. So if you se...
