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.

How to ignore user's time zone and force Date() use specific time zone
...
A Date object's underlying value is actually in UTC. To prove this, notice that if you type new Date(0) you'll see something like: Wed Dec 31 1969 16:00:00 GMT-0800 (PST). 0 is treated as 0 in GMT, but .toString() method shows the local time.

...ete, since stdout is synchronous now.
Well let's see what console.log actually does.
First of all it's part of the console module:
exports.log = function() {

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":

for(bar in foo) {
alert(foo[bar]);...
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:
WHERE myDate >= '01-01-2008' AND myDate < '01-01-2009'
Some other examples:

Git: which is the default configured remote for branch?
...ory for pushing and pulling using git-branch’s track option. You’d normally do this by specifying the --track option when creating your local master branch, but as it already exists we’ll just update the config manually like so:

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...
