Cont'd Decimal Expansion, rational or not?

Cont'd Decimal Expansion, rational or not?

This is a follow up from this question.
Since it's proven by Calvin Lin that $0.11235813213455...$ (Fibonacci
Sequence), I'm not wondering if the sequence
$$0.123456789101112131415...$$
(which is just natural numbers) is rational or not. Thanks for the help in
advanced!

Function that checks width of an image loaded by user randomly returns 0

Function that checks width of an image loaded by user randomly returns 0

I was trying to write a function that would check if the image I chose via
input[type=file] is exactly 700 px wide and if not - reject this image. I
succeeded, however, sometimes this function randomly returns 0 and I need
to load the same image a couple of times until it reads its width
correctly. Any ideas on how to improve this code? Thanks in advance!
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function(e) {
var img = new Image;
img.src = e.target.result;
if(img.width == 700) {
DoSomeStuff();
} else {
alert("This image has to be 700 px wide, but is " +
img.width + " px wide. Try again!");
input.value = "";
}
};
reader.readAsDataURL(input.files[0]);
}
