Keybase proof

I hereby claim:

• I am peterkc on github.
• I am peterkc (https://keybase.io/peterkc) on keybase.
• I have a public key whose fingerprint is 5521 24A1 2988 F388 A8D1 EFB3 40F8 0F23 FACF 3553

To claim this, I am signing this object:

async.parallel([

  copyFile.bind(null, 'resources/file3.txt', 'resources/file3_copy.txt')
], function (err, results) {

There are two reasons for that:

1. Since undefined is a property of the global object, without write-protection, it can be overridden which may result in strange and unexpected behavior when trying this: ( var == undefined).

By having an function argument undefined (the name actually does not matter) which you don't pass a parameter to, you make sure you have a variable which really is undefined so you can test "undefinedness" against this variable.

Btw. the safest method to test for undefined is: typeof ( var ) === 'undefined'

EDIT: With adoption of EcmaScript 5, undefined, NaN and Infinity are now readonly in all modern browsers - of course with the exception of Internet Explorer up to Version 9 :(. So this is not necessary anymore, however:

console.log(window); // log the "window" object to the console

I see this error when I try to suspend an Ubuntu 10 guest in Fusion:

The request to Suspend this virtual machine failed because the corresponding VMware Tools script did not run successfully.

If you have configured a custom suspend script in this virtual machine, make sure that it contains no errors. Attempting the operation again will ignore the script failure. You can also submit a support request to report this issue.

As the dialog states, the second time you try to suspend the VM it ignores the non-zero return code of the script and it seems to work. But it's annoying.

The problem appears to not be VMware actually, but Ubuntu (or Ubuntu's service script). I tried to figure out where exactly Ubuntu's initctl configuration/scripts is broken to no avail but found a work-around that I'm happy with.
