How to make phpstorm display line numbers by default?
Couldn't find that option. It's kind of annoying to turn them on manually for each page.

RESTful Alternatives to DELETE Request Body
... I concur with @Gabe, sending a body with methods which have no body by definition is a sure-fire way to randomly lose data as your bits traverse the internet pipes, and you'll have a very difficult time debugging it.

Fast permutation -> number -> permutation mapping algorithms
... + 4x. For a decimal number,
it's z + 10y + 100x. Each digit is multiplied by some weight, and the results are summed. The obvious pattern in the weight is of course that the weight is w = b^k, with b the base of the number and k the index of the digit. (I will always count digits from the right and...
Lock-free multi-threading is for real threading experts
... the interlocked operations used in lock-free multi-threading is dominated by the cache and memory-coherency tasks it must carry out.
What you gain however with a data structure that is "lock-free" is that your "locks" are very fine grained. This decreases the chance that two concurrent threads a...
Detecting Browser Autofill
...
The problem is autofill is handled differently by different browsers. Some dispatch the change event, some don't. So it is almost impossible to hook onto an event which is triggered when browser autocompletes an input field.
Change event trigger for different browsers:

Calculating moving average
...length(cx)] - cx[1:(length(cx) - n)]) / n
As pointed out in the comments by @mzuther, this assumes that there are no NAs in the data. to deal with those would require dividing each window by the number of non-NA values. Here's one way of doing that, incorporating the comment from @Ricardo Cruz:
c...

What is the purpose and use of **kwargs?
...t_name = Doe
You can also use the **kwargs syntax when calling functions by constructing a dictionary of keyword arguments and passing it to your function:
>>> kwargs = {'first_name': 'Bobby', 'last_name': 'Smith'}
>>> print_keyword_args(**kwargs)
first_name = Bobby
last_name = ...
Big O, how do you calculate/approximate it?
...unt how many times the body of the for gets executed, you need to count it by looking at what does the code do. To simplify the calculations, we are ignoring the variable initialization, condition and increment parts of the for statement.
To get the actual BigOh we need the Asymptotic analysis of t...
Why are C++ inline functions in the header?
...in every translation unit that uses it.
The easiest way to achieve this is by putting the definition in a header file.
If you want to put the definition of a function in a single source file then you shouldn't declare it inline. A function not declared inline does not mean that the compiler cannot i...
