Does functional programming replace GoF design patterns?
Since I started learning F# and OCaml last year, I've read a huge number of articles which insist that design patterns (especially in Java) are workarounds for the missing features in imperative languages. One article I found makes a fairly strong claim :

How to put the legend out of the plot
... try playing around with placing the legend in different places:
So, let's start with a generic example:
import matplotlib.pyplot as plt
import numpy as np
x = np.arange(10)
fig = plt.figure()
ax = plt.subplot(111)
for i in xrange(5):
ax.plot(x, i * x, label='$y = %ix$' % i)
ax.legend()

Difference between std::system_clock and std::steady_clock?
...
Maybe, the most significant difference is the fact that the starting point of std::chrono:system_clock is the 1.1.1970, so-called UNIX-epoch.
On the other side, for std::chrono::steady_clock typically the boot time of your PC and it's most suitable for measuring intervals.

CSS: fixed position on x-axis but not y?
... for the answer.
The easiest way to understand how DNA is organized is to start with its basic building blocks. DNA consists of four different sugars that interact with each other in specific ways. These four sugars are called nucleotide bases and have the names adenine (A), thymine (T), cytosine (...
Fixed point vs Floating point number
...
floating point usage becomes a problem when you start doing calculations with them like for instance if you add a really small and a really large floating point number together. The summed result loses accuracy since it has to represent a number with two extremes and the l...

Of course as you start to build a larger scale and more sophisticated solution around Redis you are re-implementing many of the features that have already been solved using, Celery, Apache Spark and Hadoop, Zookeeper, etcd, Cassandra and so o...

What guarantees are there on the run-time complexity (Big-O) of LINQ methods?
I've recently started using LINQ quite a bit, and I haven't really seen any mention of run-time complexity for any of the LINQ methods. Obviously, there are many factors at play here, so let's restrict the discussion to the plain IEnumerable LINQ-to-Objects provider. Further, let's assume that any...
