What's wrong with Groovy multi-line String?
...two try to make "test" positive (and this is where it fails)
With the new String constructor method, the Groovy parser is still in the constructor (as the brace hasn't yet closed), so it can logically join the three lines together into a single statement
For true multi-line Strings, you can also u...
Non-Relational Database Design [closed]
...DBs are a massive win, and the drawbacks of less flexible queries and some extra code for data validation seems a small price to pay.
Have you hit your head against anything that seems impossible?
Not yet. Map/reduce as a means of querying a database is unfamiliar, and requires a lot more thinking...
Sort array of objects by single key with date value
...the array using your current updated_at in ISO format. We use new Data(iso_string).getTime() to convert ISO time to Unix timestamp. A Unix timestamp is a number that we can do simple math on. We subtract the first and second timestamp the result is; if the first timestamp is bigger than the second t...
Example of multipart/form-data
...rt/mixed header in a multipart/form-data, simply choosing another boundary string inside multipart/mixed and using that one to incapsulate data. At the end, you must "close" all boundary used in FILO order to close the POST request (like:
POST / HTTP/1.1

int a[] = {1,2,}; Weird comma allowed. Any particular reason?
...at the end.
e.g.
for_each(my_inits.begin(), my_inits.end(),
[](const std::string& value) { std::cout << value << ",\n"; });
There isn't really any advantage for the programmer.
P.S. Though it is easier to autogenerate the code this way, I actually always took care not to put the ...

Safely limiting Ansible playbooks to a single machine?

Why not infer template parameter from constructor?
...nd operator=). So suppose you are using your class like this :
MyClass m(string s);
MyClass *pm;
*pm = m;
I am not sure if it would be so obvious for the parser to know what template type is the MyClass pm;
Not sure if what I said make sense but feel free to add some comment, that's an interest...
How to make pipes work with Runtime.exec()?
...ds.
Pipe is a part of the shell, so you can also do something like this:
String[] cmd = {
"/bin/sh",
"-c",
"ls /etc | grep release"
};
Process p = Runtime.getRuntime().exec(cmd);

Fluid width with equally spaced DIVs

<span class="stretch"></span>
</div>
The extra span (.stretch) can be replaced with :after.
This still works in all the same browsers as the above solution. :after doesn't work in IE6/7, but they're using distribute-all-lines anyway, so it doesn't matter.
