Representational state transfer (REST) and Simple Object Access Protocol (SOAP)
...
@TomHall I guess this situation is a bit specific to REST - RPC discussion, not only on SO. I guess that is the reason we don't have reasonable tooling for REST clients. At least on .NET, implementing a REST service client has proved to be way more difficult tha...
Finding a branch point with Git?
... master
So, the goal: find B. Here are three ways that I found, after a bit of tinkering:
1. visually, with gitk:
You should visually see a tree like this (as viewed from master):
or here (as viewed from topic):
in both cases, I've selected the commit that is B in my graph. Once you cl...
Hidden Features of C++? [closed]
... C++ programmers are familiar with the ternary operator:
x = (y < 0) ? 10 : 20;
However, they don't realize that it can be used as an lvalue:
(a == 0 ? a : b) = 1;
which is shorthand for
if (a == 0)
a = 1;
else
b = 1;
Use with caution :-)

How can I plot with 2 different y-axes?
...dd an axis label on the right-hand side. Here is an example using a little bit of made-up data:
set.seed(101)
x <- 1:10
y <- rnorm(10)
## second data set on a very different scale
z <- runif(10, min=1000, max=10000)
par(mar = c(5, 4, 4, 4) + 0.3) # Leave space for z axis
plot(x, y) # fir...

CSS: Set a background color which is 50% of the width of the window
...
position: fixed;
top: 0;
left: 0;
width: 50%;
height: 100%;
background-color: pink;
}
Example: http://jsfiddle.net/PLfLW/1704/
The solution uses an extra fixed div that fills half the screen. Since it's fixed, it will remain in position even when your users scroll. You m...
What is `related_name` used for in Django?
...el, User.map_set will still work, but the User.maps. syntax is obviously a bit cleaner and less clunky; so for example, if you had a user object current_user, you could use current_user.maps.all() to get all instances of your Map model that have a relation to current_user.

Using the HTML5 “required” attribute for a group of checkboxes?
...
Inspired by the answers from @thegauraw and @Brian Woodward, here's a bit I pulled together for JQuery users, including a custom validation error message:
$cbx_group = $("input:checkbox[name^='group']");
$cbx_group.on("click", function() {
if ($cbx_group.is(":checked")) {
// checkb...
