Rspec doesn't see my model Class. uninitialized constant error
... versions of RSpec move some stuff out of the spec/spec_helper.rb file, so now you also get a spec/rails_helper.rb file. If you run rails generate rspec:install, this is what it produces (rspec-rails 3.0.1, rails 4.1.1). Turns out the rails_helper.rb file contains some similar code to yours and shou...
matplotlib does not show my drawings although I call pyplot.show()
...
This answer is old, config should now be in ~/.config/matplotlib/matplotlibrc (for python 3, at least). I just had a related problem, and I think it was caused by using matplotlib in python 2.7, which created a ~/.matplotlib/ directory, and stopped python 3 f...
Why doesn't print work in a lambda?
...
Now I see why it was such a big deal to make it a function. Wanted to use print as a default kwarg and this fixed it. Thanks.

What's the purpose of using braces (i.e. {}) for a single-line if or loop?
...think of is nested if's:
if (cond1)
if (cond2)
doSomething();
Now, assume you now want to doSomethingElse() when cond1 is not met (new feature). So:
if (cond1)
if (cond2)
doSomething();
else
doSomethingElse();
which is obviously wrong, since the else associates with the ...
How do you rotate a two dimensional array?
...eed this information in our function to rotate a matrix, so let’s add it now:
def rotate(matrix):
size = len(matrix)
# Rotatable layers only.
layer_count = size / 2
Now we know what layers are and how to determine the number of layers that actually need rotating, how do we isolate a...
How do I write a bash script to restart a process if it dies?
...and crashing on your hands. The sleep 1 takes away the strain from that.
Now all you need to do is start this bash script (asynchronously, probably), and it will monitor myserver and restart it as necessary. If you want to start the monitor on boot (making the server "survive" reboots), you can s...
WAMP/XAMPP is responding very slow over localhost
I don't know what the problem is. WAMP was very slow, so I reformatted my computer and installed WAMP. Still, accessing localhost is very, very slow, and sometimes it doesn't even load at all. I even removed it and replaced it with XAMPP, but I still got the same result. What might possibly be the p...

...functionality to locate the classes that implemented a given interface. I know the functions were hidden in some non-logical place, but they could be used for other classes as the package name implied. Back then I did not need it, so I forgot about it, but now I do, and I can't seem to find the func...
Why is TypedReference behind the scenes? It's so fast and safe… almost magical!
