Can hash tables really be O(1)?
... an input of size n for you to insert in your table.
The question is: how fast is your hash table on the adversary input?
From step (1) the adversary knows your hash function; during step (2) the adversary can craft a list of n elements with the same hash modulo m, by e.g. randomly computing the h...
Best practices/guidance for maintaining assembly version numbers
...
There is no hard and fast rule when it comes to versioning assemblies, so feel free to try which ever would work for you, but I would suggest you make use of 4 parts approach as you will have the flexiblity incase you want to make some changes ...

How to use glOrtho() in OpenGL?
...can do the thousands of matrix multiplications for different points really fast in parallel.
Manually written vertex shaders then do the multiplication explicitly, usually with the convenient vector data types of the OpenGL Shading Language.
Since you write the shader explicitly, this allows you t...
In C++, is it still bad practice to return a vector from a function?
...sing the vector capacity instead of re-allocating a second vector is 1.37x faster.
When numIter = 256, reusing the vector capacity (instead of allocating/deallocating a vector over and over again 256 times...) is 2.45x faster :)
We can notice that time1 is pretty much constant from numIter = 1 to...
Xamarin 2.0 vs Appcelerator Titanium vs PhoneGap [duplicate]
...ed (not with jQuery.Mobile, though). We tried jqMobi (not very mature, but fast).
Very limited capability for interaction with other apps or cdevice capabilities, and this would not be cross-platform anyway, as there aren't any standards in HTML5 except for a few, like geolocation, camera and local ...
How do I merge two dictionaries in a single expression in Python (taking union of dictionaries)?
...uld not use:
z = dict(x, **y)
This uses the dict constructor, and is very fast and memory efficient (even slightly more-so than our two-step process) but unless you know precisely what is happening here (that is, the second dict is being passed as keyword arguments to the dict constructor), it's di...
How do I plot in real-time in a while loop using matplotlib?
...fline or very slowly changing data to now you can use Matplotlib with very fast updating data... almost like an oscilloscope).

How can I improve my paw detection?
...e GIF images below on my machine, so the paw detection algorithm is fairly fast...)
Here's a full example (now with much more detailed explanations). The vast majority of this is reading the input and making an animation. The actual paw detection is only 5 lines of code.

How to train an artificial neural network to play Diablo 2 using visual input?
...e a huge milestone for games AI!
UPDATE 2017-01: The field is moving very fast since AlphaGo's success, and there are new frameworks to facilitate the development of machine learning algorithms on games almost every months. Here is a list of the latest ones I've found:
