What's the best way to bundle static resources in a Go program? [closed]
...eveloper's machine to help debug their applications/web services. The interface to the program is a web page which includes not only the HTML, but some JavaScript (for functionality), images and CSS (for styling). I'm planning on open-sourcing this application, so users should simply be able to run ...
What happens to a declared, uninitialized variable in C? Does it have a value?
... older architectures.
Attempting to work with a value with these flag bits set can result in a CPU exception in an operation that really shouldn't fail (eg, integer addition, or assigning to another variable). And if you go and leave a variable uninitialized, the compiler might pick up some random g...
How do I get the path of a process in Unix / Linux
...e's a suitable executable binary with the same name.

How to prevent moment.js from loading locales with webpack?
...
When you set resolve aliases, they apply to any usage of import or require in your system (including libraries you depend on). So if a module you depend on required moment, you would be changing the result for that module as well. Thi...
Search for executable files using find command
...ype f -perm +111 -print
In this context "+" means "any of these bits are set" and 111 is the execute bits.
Note that this is not identical to the -executable predicate in GNU find. In particular, -executable tests that the file can be executed by the current user, while -perm +111 just tests if a...

If you're using ruby 1.8.7 or 1.9, you can use the fact that iterator methods like each_with_index, when called without a block, return an Enumerator object, which you can call Enumerable methods like map on. So you can do:
a...
How can I format a String number to have commas and round?
...d here. You call it like this:
public static void main(String[])
{
int settings = ValueFormat.COMMAS | ValueFormat.PRECISION(2) | ValueFormat.MILLIONS;
String formatted = ValueFormat.format(1234567, settings);
}
I should also point out this doesn't handle decimal support, but is very useful...
Converting bool to text in C++
...rt a boolean value to a string such that 1 turns to "true" and 0 turns to "false"? I could just use an if statement, but it would be nice to know if there is a way to do that with the language or standard libraries. Plus, I'm a pedant. :)

map function for objects (instead of arrays)
...r
{ a : 1, b: 4, c: 9 }
NB: this version also allows you to (optionally) set the this context for the callback, just like the Array method.
EDIT - changed to remove use of Object.prototype, to ensure that it doesn't clash with any existing property named map on the object.

How can I get `find` to ignore .svn directories?
...@Kaleb: As comparing the file type (equivalent to testing whether a bit is set in an integer) is faster than comparing the filename (equivalent to a string comparison, which is O(n)), putting -type d before -name .svn is theoretically more efficient. However, it is usually insignificant except if yo...
