Getting a better understanding of callback functions in JavaScript
...nd having it execute, but I'm not understanding the best implementation to do that. I'm looking for a very basic example, like this:

Traversing text in Insert mode
...ery familiar with it.
The right way is to press Esc, go where you want to do a small correction, fix it, go back and keep editing. It is effective because Vim has much more movements than usual character forward/backward/up/down. After you learn more of them, this will happen to be more productiv...
How can I create a Makefile for C projects with SRC, OBJ, and BIN subdirectories?
...cessfully!"
The $(TARGET) rule has the same problem that the target name does not actually describe what the rule builds. For that reason, if you type make several times, Make will rebuild the target each time, even though there is no reason to. A small change fixes that:
$(BINDIR)/$(TARGET): $(O...
Can I Install Laravel without using Composer?
...
If you really wanted to, you could do all the work that Composer does manually, but you definitely should not. Installing Composer is easy, it's just a matter of getting the composer.phar file and running commands on it.
You do not need to run Composer on you...
TreeMap sort by value
...dEntries.addAll(map.entrySet());
return sortedEntries;
}
Now you can do the following:
Map<String,Integer> map = new TreeMap<String,Integer>();
map.put("A", 3);
map.put("B", 2);
map.put("C", 1);
System.out.println(map);
// prints "{A=3, B=2, C=1}"

What is a Question Mark “?” and Colon “:” Operator Used for? [duplicate]
..." and colon ":" operator within the parentheses of a print function: What do they do? Also, does anyone know the standard term for them or where I can find more information on their use? I've read that they are similar to an 'if' 'else' statement.

Store a closure as a variable in Swift
...ure, i.e. a closure taking
a float argument. The following would assign a "do nothing" closure to the
completion handler:
var completionHandler: (Float)->Void = {
(arg: Float) -> Void in
}
and this can be shortened to
var completionHandler: (Float)->Void = { arg in }
due to the au...
Why would introducing useless MOV instructions speed up a tight loop in x86_64 assembly?
...ed the alias and allowed the branch to be predicted correctly
Your Core2 doesn't keep a separate history record for each conditional jump. Instead it keeps a shared history of all conditional jumps. One disadvantage of global branch prediction is that the history is diluted by irrelevant informat...
