Truly understanding the difference between procedural and functional
..., the functional style emphasizes the combination of functions required to transform the initial input to the final output.
The example also shows the typical relative sizes of procedural versus functional code. Furthermore, it demonstrates that the performance characteristics of procedural code m...
What does the “map” method do in Ruby?
...vid", "thomas"].map(&:upcase)
#=> ["VANESSA", "DAVID", "THOMAS"]
Transforming data in Ruby often involves a cascade of map operations. Study map & select, they are some of the most useful Ruby methods in the primary library. They're just as important as each.

Fixed stroke width in SVG
...pixel-aware", that is always be 1px wide regardless of the current scaling transformations applied. I am aware that this may well be impossible, since the whole point of SVG is to be pixel independent.

How do you easily horizontally center a using CSS? [duplicate]
... The code follows.
.centered {
position: relative;
left: 50%;
transform: translateX(-50%);
}
What this does is:
Position the div relative to its container;
Position the div's left boundary at 50% of its container width horizontally;
Translate back horizontally by 50% of the div's o...
How to convert a PIL Image into a numpy array?
...ect back and forth to a numpy array so I can do some faster pixel by pixel transformations than PIL's PixelAccess object would allow. I've figured out how to place the pixel information in a useful 3D numpy array by way of:
