Trying to fix line-endings with git filter-branch, but having no luck
...
My procedure for dealing with the line endings is as follows (battle tested on many repos):
When creating a new repo:
put .gitattributes in the very first commit along with other typical files as .gitignore and README.md
When dealing with an existing repo:

Indent starting from the second line of a paragraph with CSS
...first word in a para. A cumbersome one-off solution is to place text in an SVG element and position this the same as an <img>. Using float and the SVG's height tag defines how many rows will be indented e.g.
<p style="color: blue; font-size: large; padding-top: 4px;">
<svg height="44...
How to wait for a keypress in R?
... colored, waiting for the next keystroke on the keyboard.
Compatibility: Tested under environments use either win.graph or X11. Works with Windows 7 x64 with Revolution R v6.1. Does not work under RStudio (as it doesn't use win.graph).

Why doesn't the example compile, aka how does (co-, contra-, and in-) variance work?
...ranslating their example to use your construct:
val x = new Slot[String]("test") // Make a slot
val y: Slot[Any] = x // Ok, 'cause String is a subtype of Any
y.set(new Rational(1, 2)) // Works, but now x.get() will blow up
If you feel I'm not understanding your question (a dis...

...ge you can.)
Just like PNG-8, PNG-24 supports alpha-transparency, too.
SVG - Lossless / Vector

Rebasing and what does one mean by rebasing pushed commits
...ID (in this case, a, b, c, and d). You'll notice that d is currently the latest commit (or HEAD) of the master branch.
Here, we have two branches: master and my-branch. You can see that master and my-branch both contain commits a and b, but then they start to diverge: master contains c and d, whil...
What's the difference between a catalog and a schema in a relational database?
...per host computer (or virtual OS). Multiple clusters is commonly done, for testing and deploying new versions of Postgres (ex: 9.0, 9.1, 9.2, 9.3, 9.4, 9.5).
If you did have multiple clusters, imagine the diagram above duplicated.
Different port numbers allow the multiple clusters to live side-by...
Measure time in Linux - time vs clock vs getrusage vs clock_gettime vs gettimeofday vs timespec_get?
... and does not wrap around. The precision on my system is 1 µs, but I also tested it on a Linux system (Red Hat 4.1.2-48 with GCC 4.1.2) and there the precision was only 1 ms.
gettimeofday() returns the wall-clock time with (nominally) µs precision. On my system this clock does seem to have µs pre...
