How can I get the sha1 hash of a string in node.js?
...
Good idea. Note, however, that all objects (except arrays and null) will have the same sha1sum value since Object.toString() returns [object Object] by default. So sha1sum({}) === sha1sum({"foo":"bar"}) === sha1sum({"a":1}), etc.

Is the order of elements in a JSON list preserved?
...
Practically speaking, if the keys were of type NaN, the browser will not change the order.
The following script will output "One", "Two", "Three":
var foo={"3":"Three", "1":"One", "2":"Two"};

What makes a SQL statement sargable?
...L optimizer can't use an index on myDate, even if one exists. It will literally have to evaluate this function for every row of the table. Much better to use:

Should import statements always be at the top of a module?
...t that's only paid once.
Putting the imports within a function will cause calls to that function to take longer.
So if you care about efficiency, put the imports at the top. Only move them into a function if your profiling shows that would help (you did profile to see where best to improve perform...
Segmentation fault on large array sizes
...The array is too big to fit in your program's stack address space.
If you allocate the array on the heap you should be fine, assuming your machine has enough memory.
int* array = new int[1000000];
But remember that this will require you to delete[] the array. A better solution would be to use st...

PHP equivalent of .NET/Java's toString()
...
@MarkAmery He gave an answer that implicitly calls the __toString() "Magic Method", but didn't mention that at all. The user asked for an answer that was like the Java toString() method, and in PHP, that's the __toString() function.

$ end=${end[@]: -1} # get the last one
$ echo $end

That illustrates how to get the last element of an array. You'll often see this:
$ echo ${array[${#array[@]} - 1]}

What do *args and **kwargs mean? [duplicate]
...r **kwargs as the last items in your function definition’s argument list allows that function to accept an arbitrary number of arguments and/or keyword arguments.
For example, if you wanted to write a function that returned the sum of all its arguments, no matter how many you supply, you could wr...
