Not at all: it's you who don't seem to have read the post. He reaches a person, who completely fails to help in any way. Eventually after a further series of emails, someone cancels his order and fails to ship him the actual phone he'd been waiting for. I can't see how calling Support earlier would have helped.

You are right, I confused Saurabh and Æsa. However, 5 days after calling, he received an offer to cancel the purchase & disable the device, which may indicate that the phone call did help trigger something.

What an extremely irritating blog. For some reason the owner seems to have linked the pagedown key to the "previous article" link. If I press the pagedown key, it's because I want to read the text that's currently off the screen, not because I want to read the previous article. You're actually preventing me from reading your full text. Fail.

Pagedown scrolls down the page for me.

I note that the writer has fallen into the trap of a false cognate - or, at least, a near-homonym - by writing "demure" when he/she meant "demur".

I think a better Python version would be

    print '\n'.join(['Hello world'] * 100)

No need for exec.

I wonder why 430gj9j added exec..

  print "Hello world\n"*100

Would have worked just fine.

He abstracted this loop:

    for i in xrange(100):
        statement

into:

   exec "statement" * 100

The 'no exec' alternatives propose something not as generic since they can only print something a number of times.

Or just

    print "Hello, World\n" * 100

No need for join either, and ends with a newline

I'm glad you found it easy. Personally, I found it very challenging: although I thought I matched the requirements for mathematical background that Prof Roughgarden outlined in the intro lecture, it turned out to be a struggle to keep up with some of the concepts when it came to apply them in the theory questions.

The programming exercises were fun, but I don't think they were really the point of the course - this "part 1", at least, was much more about analysis than about design.

As a contrast, I've just started their compilers course: there the theory questions are slightly easier, whereas the programming questions are much more involved - the first one has already taken me several hours and I'm nowhere near finished.
