This works with other types of resources like strings.xml, integers.xml, arrays.xml, etc.
Configure Signing Settings
To manually configure the signing configurations for your release build type using Gradle build configurations:
1.Create a keystore. A keystore is a binary file that contains a s...
What are the applications of binary trees?
...L tree has kept itself as compact and balanced as possible.
In a sorted array, lookups would still take O(log(n)), just like a tree, but random insertion and removal would take O(n) instead of the tree's O(log(n)). Some STL containers use these performance characteristics to their advantage so in...
Good or bad practice? Initializing objects in getter
...ider all optimizations. For instance, in the .NET classes you will see bit arrays used for Boolean class variables throughout the code to reduce memory consumption and memory fragmentation, just to name two "micro-optimizations".

You are not going to use lazy initialization...

How to get different colored lines for different plots in a single figure?
...gure()
ax1 = fig1.add_subplot(111)
for i in range(1,15):
ax1.plot(np.array([1,5])*i,label=i)
The piece of code that you need:
colormap = plt.cm.gist_ncar #nipy_spectral, Set1,Paired
colors = [colormap(i) for i in np.linspace(0, 1,len(ax1.lines))]
for i,j in enumerate(ax1.lines):

Swift and mutating struct
...ted as either constants (via let) or variables (via var)
Consider Swift's Array struct (yes it's a struct).
var petNames: [String] = ["Ruff", "Garfield", "Nemo"]
petNames.append("Harvey") // ["Ruff", "Garfield", "Nemo", "Harvey"]
let planetNames: [String] = ["Mercury", "Venus", "Earth", "Mars", ...
What does the brk() system call do?
...and dole it out yourself. If you keep the nodes of your binary tree in an array, you can use 8b or 16b indices instead of 64b pointers. This works great when you don't have to delete any node until you're ready to delete all the nodes. (e.g. build a sorted dictionary on the fly.) Using sbrk for ...
What are the differences between Perl, Python, AWK and sed? [closed]
...h no storage from line to line. awk is often used to build up associative arrays with data accumulated from all the sources; it uses more memory, and is therefore much more likely to run into problems with large data sets than sed is. I've not heard of tsawk before you linked to it. I tend to fall ...
What's the difference between __PRETTY_FUNCTION__, __FUNCTION__, __func__?
...
__func__ is an implicitly declared identifier that expands to a character array variable containing the function name when it is used inside of a function. It was added to C in C99. From C99 §6.4.2.2/1:
The identifier __func__ is implicitly declared by the translator as if, immediately followin...
