PHP Session Fixation / Hijacking
...sion.entropy_file and session.entropy_length in your php.ini file. Set the former to session.entropy_file = /dev/urandom and the latter to the number of bytes that will be read from the entropy file, for example session.entropy_length = 256.
Change the name of the session from the default PHPSESSID...

What are “named tuples” in Python?
...gt; pt1.x = 2.0
>>> print(pt1[0])
2.0
I am not aware of any form of "named list" that lets you add new fields, however. You may just want to use a dictionary in this situation. Named tuples can be converted to dictionaries using pt1._asdict() which returns {'x': 1.0, 'y': 5.0} and ca...
Analyze audio using Fast Fourier Transform
...
The array you are showing is the Fourier Transform coefficients of the audio signal. These coefficients can be used to get the frequency content of the audio. The FFT is defined for complex valued input functions, so the coefficients you get out will be imaginary numbers...
Non-Relational Database Design [closed]
...I don't want a "table-oriented graph" and the like. However, here's some information on automatic translation from RDBMS to graphdb.
Explicit data models: I do these all the time (whiteboard style), and then use the model as it is in the DB as well.
Miss from RDBMS world: easy ways to create repor...
rsync: difference between --size-only and --ignore-times
...mpare the static checksum of source and destination.
These checks are performed before transferring data. Notably, this means the static checksum is distinct from the stream checksum - the later is computed while transferring data.
By default, rsync uses only 1 and 2. Both 1 and 2 can be acquired...

Maybe as a Functor
The idea of transforming one type to another one such that operations on the old type can also be transformed to work on the new type is the concept behind the Haskell type class called Functor, which Maybe a has a useful instance of.
Functo...
Why use Object.prototype.hasOwnProperty.call(myObj, prop) instead of myObj.hasOwnProperty(prop)?
...d therefore won't have hasOwnProperty() available on it. Using your second form would fail to work for this reason.
It's also a safer reference to Object.prototype.hasOwnProperty() (and also shorter).
You can imagine someone may have done...
var someObject = {
hasOwnProperty: function(lol) {

How is Math.Pow() implemented in .NET Framework?
...ind-the-scene of calculations:
I've tried some workarounds on a coding platform which has an extensive test coverage cases, and found a very effective way doing it(Solution 3):
