MemoryCache does not obey memory limits in configuration
...s intended, tested out with a generator which fills up cache with loads of strings of 1000 characters. Although, adding up what should be like 100MB to the cache adds up actually 200 - 300MB to the cache, which I found quite strange. Maybe some overheards I'm not counting.

... Bonus: in the end the exit status is actually an exit status and not some string in a file.
Situation:
someprog | filter
you want the exit status from someprog and the output from filter.
Here is my solution:

How to write file if parent folder doesn't exist?
...t the easiest way to do this is to use the outputFile() method from the fs-extra module.
Almost the same as writeFile (i.e. it overwrites), except that if the parent directory does not exist, it's created. options are what you'd pass to fs.writeFile().
Example:
var fs = require('fs-extra');

What is the best way to determine the number of days in a month with JavaScript?
...
To take away confusion I would probably make the month string based as it is currently 1 based.
function daysInMonth(month,year) {
monthNum = new Date(Date.parse(month +" 1,"+year)).getMonth()+1
return new Date(year, monthNum, 0).getDate();
}
daysInMonth('feb', 2015)

How can I check for “undefined” in JavaScript? [duplicate]
...e undefined, then use the typeof operator, which is guaranteed to return a string:
if (typeof myVar !== 'undefined')
Direct comparisons against undefined are troublesome as undefined can be overwritten.

Echo a blank (empty) line to the console from a Windows batch file [duplicate]
... @MatteoItalia, It's nothing to do with speed. If it's doing something extra (search first for a file named echo without extension) then it's wrong and if there's a file as such, it'll indeed fail.

other objects.
