Is there any way to put malicious code into a regular expression?
...at most HTTP servers provide.
There are various ways to implement these, ranging form a simple alarm(N) at the C level, to some sort of try {} block the catches alarm‐type exceptions, all the way to spawning off a new thread that’s specially created with a timing constraint built right into it...
Why are these constructs using pre and post-increment undefined behavior?
... imposes no requirements
and notes that:
Possible undefined behavior ranges from ignoring the situation completely with unpredictable results, to behaving during translation or program execution in a documented manner characteristic of the environment (with or without the issuance of a diagnos...
What is the difference between Elastic Beanstalk and CloudFormation for a .NET project?
...ons. AWS CloudFormation is a convenient provisioning mechanism for a broad range of AWS and third party resources. It supports the infrastructure needs of many different types of applications such as existing enterprise applications, legacy applications, applications built using a variety of AWS res...
How many socket connections can a web server handle?
...application. In theory, this is solved by using all addresses in 127.*.*.* range, but in practice I don't know if this is an available option.

Strip HTML from strings in Python
...xception.
Numeric HTML entities specifying code points outside the Unicode range acceptable by Python (such as, on some systems, characters outside the Basic Multilingual Plane) will cause a ValueError exception.
Security note: Do not confuse HTML stripping (converting HTML into plain text) with H...
how do I initialize a float to its max/min value?
... negative number and FLT_MAX (or DBL_MAX) for positive. This gives you the range of possible float (or double) values.
You probably don't want to use FLT_MIN; it corresponds to the smallest magnitude positive number that can be represented with a float, not the most negative value representable wit...
Moving matplotlib legend outside of the axis makes it cutoff by the figure box
...ort matplotlib.pyplot as plt
import numpy as np
plt.gcf().clear()
x = np.arange(-2*np.pi, 2*np.pi, 0.1)
fig = plt.figure(1)
ax = fig.add_subplot(111)
ax.plot(x, np.sin(x), label='Sine')
ax.plot(x, np.cos(x), label='Cosine')
ax.plot(x, np.arctan(x), label='Inverse tan')
handles, labels = ax.get_lege...
Declaring variables inside loops, good practice or bad practice?
...rate. From a reviewer perspective, it's much nicer, since he has less long range state variables to worry about and track.
Even the compiler will help better : assuming that, in the future, after some erroneous change of code, result is not properly initialized with f2(). The second version will si...
Does functional programming replace GoF design patterns?
...omplex the thoughts you can express. Having a rich, shared vocabulary at a range of scales - from system architecture down to bit twiddling - allows us to have more intelligent conversations, and thoughts about what we should be doing.
We can also, as individuals, learn. Which is the entire point o...
How to put the legend out of the plot
...neric 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()
plt.show()
If we do the same thing, but use the bbox_to_anchor keyword argument we can shif...
