I like to use a variation of this in vim to quickly see if an html doc I'm working on contains weird characters that I might want to replace with &html; entities:

  /[^ -~]

The example given illustrates one of the flaws of almost all todo implementations: "Study for math exam" - you can never check this off the list because it can't be discretely finished.

You said "almost". Do you know one that handles continuous tasks well?

I found this great little jQuery bookmarklet generator from Ben Alman:

http://benalman.com/code/test/jquery-run-code-bookmarklet/

You can just paste this code in and generate yourself a bookmarklet to reveal the quora answers (should work on all browsers).

  $('.blurred_answer_wrapper').removeClass('blurred_answer_wrapper');
  $('.with_signup').removeClass('with_signup');
  $('.signup_cta_on_answer').remove();

Let's see if HN allows this long link directly to the generated bookmarklet:

Yeah, there's nothing magical about the actual implementation (there are a couple more lines in the repo, though).

The Chrome extension is nice because it automatically executes on quora.com (and not elsewhere). Install and forget.

Even the 'I' looks wrong. Well done.

Is it? (Looks again.) Oh, I see what you mean, but is it "impossible"? It looks like a falling tall skyscrapper from the ground point perspective.

To me, many of them are not what I would call impossible. Looking them over I think I could recreate many of them in a 3D program easily enough. The only ones that fit that name seem to be the ones with a horizontal element connecting two vertical elements. Even then many of those where the horizontal is on the bottom or top, like T, U, V, W, seem to work. I wouldn't call this a collection of "impossible" letters but a nice typeface inspired by an impossible object, just like it says next to the name.

I think you could make an object like that, but you'd need to take a rectangular prism and bend it - the top and bottom of the I look like they are receding from you.

It's easy to call it a meaningless interaction, but it's far from meaningless. He's explicitly breaking an implicit trust between himself and the reader. He's saying "Hey reader, I'm watching you."

If you don't think this is a big deal, I invite you to think about a natural extension of this concept: A comment form that sends its entire contents to the server on every keypress.

Stop wondering and get a browser or extension that will somehow explicitly notify you when a connection is active.

The keypresses could be stored until the form is sent, the javascript doing this could be heavily obfuscated, the message could be encrypted.

This, while cool, just seems like the wrong way to go about things. I like this solution or something like it: https://github.com/mindbrix/UIImage-PDF
