How can I tell if one commit is a descendant of another commit?

If you want to check this programmatically (e.g. in script), you can check if git merge-base A B is equal to git rev-parse --verify A (then A is reachable from B), or if it is git rev-parse --verify B (then B is reachable from A). git rev-parse is here needed to convert from ...
Get an array of list element contents in jQuery

And in clean javascript:
var texts = [], lis = document.getElementsByTagName("li");
for(var i=0, im=lis.length; im>i; i++)
texts.push(lis[i].firstChild.nodeValue);

Compare JavaScript Array of Objects to Get Min / Max

val = cmp(val, arr[i][attr])
}
return val;
}
alert(finder(Math.max, myArray, "Cost"));
alert(finder(Math.min, myArray, "Cost"));
or if you had a deeply nested structure, you could get a little more functional and do the following:
var myArray =
[
{"ID": 1, "Cost...

HTML5shiv vs Dean Edwards IE7-js vs Modernizr - which to choose?
...tags in IE, like html5shiv.
ie7.js (as well as ie8.js and ie9.js) uses Javascript to retro-fit some missing functionality to IE.
As far as I'm aware there's no cross-over between them (aside from html5shiv/modernizr), so you can use any combination of them, depending on what features you need to i...

Python's json module, converts int dictionary keys to strings
...ect properties are converted to String.
var a= {1: 'a'};
for (k in a)
alert(typeof k); // 'string'
This can lead to some curious-seeming behaviours:
a[999999999999999999999]= 'a'; // this even works on Array
alert(a[1000000000000000000000]); // 'a'
alert(a['999999999999999999999']); // fail

Is it secure to store passwords as environment variables (rather than as plain text) in config files
...ly a local environment variable, like "set pwd=whatever," and then run the script,
with something that exits your command shell at the end of the script, then the variable no longer exists.
Your case falls into the first two, which I'd say is fairly insecure. If you were going to do this, I wo...
