> Or you can represent the music as instructions to performers or synthesizers (ie notation) and you've got as many dimensions as you want.

These are just multiple signals in a single dimension (time).

1 physical dimension. Mathematically, each signal is a dimension.

Ah, you beat me to it.

A practical demonstration of XSS in an SVG is the following:

  <?xml version="1.0" standalone="no"?>
  <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">

  <svg version="1.1" baseProfile="full" xmlns="http://www.w3.org/2000/svg">
    <polygon id="triangle" points="0,0 0,50 50,0" fill="#009900" stroke="#004400"/>
    <script type="text/javascript">
      alert(document.cookie);
    </script>
  </svg>

I see this in the wild all the time, though these days it's becoming less harmful as more developers learn to host their images (and all user uploaded files, really) on a separate CDN.

That's exactly the same as regular HTML

I don't know, to me, I treat Airbnbs and Ubers considerably nicer than respective hotels and taxis because they are real peoples' personal property (I even do the dishes for Airbnb owners even though I'm not supposed to).

I guess I'm in the minority.

Lesson learned.

At what point of sharing does something become unworthy of respect? Is a married couple's property unworthy? A family's? A group of roommates?

>what does that even mean?

It's precisely analogous: the age of oil will be "over" long before we run out of oil. That's how resource economics work.

tamana · 9 years ago

It's not. The stone age ended because we invented better tech, without raising stone prices. Oil costs will rise.

You could buy additional insurance if you're actually worried about this.

Or you could short their stock as a hedge, and buy some options to cover the upside risk.

Or you could buy the car using a title-backed no-recourse loan, pushing this risk onto the lender.

Or you could lease the car rather than buy it.

tamana · 9 years ago

If you lease the car, the monthly price doubles.

The curving process should be linear, I think.

tamana · 9 years ago

That sounds funny, but it's true under the common modern curving regime that is really just lowering the bar for raw score to letter grade conversion, not forcing a bell curve.

"Are CS grades bimodal, or unimodal? To test this, we ac- quired the final grades distributions for every undergraduate CS class at the University of British Columbia (UBC), from 1996 to 2013. This represents 778 different lecture sections, containing a total of 30,214 final grades (average class size: 75)."

My understanding of the bimodal situation, if it exists, is that it primarily applies to earlier classes---later classes only include those who did well, or at least passed, the previous classes.

Ah, yes...

"Of the 45 classes which were multimodal, 16 were 100- level classes (35%), 5 were 200-level (11%), 12 were 300-level (27%), and 12 were 400-level (27%). For comparison, in the full set of 778 classes, 171 were 100-level (22%), 165 were 200-level (21%), 243 were 300-level (31%), and 199 were 400-level (26%)."

How about we take a closer look at those 100 level classes, hmmm?

tamana · 9 years ago

100 level classes werent substantiallly more often bimodal than the others though.

Most books I've seen use C rather than C#. Bad editor if they don't.

Microsoft, the inventor and trademark owner, use # on their website.

In my opinion the sharp symbol is very different from the hash symbol #. If you argue that these two are the same symbol, then so would be "d" and "q".

tamana · 9 years ago

You were correct before ASCII and English keyboards and Microsoft C# gave the # an expanded role out of convenience

It's a bit like how a lot of people refer to '#' as 'hashtag' these days, without knowing about 'the pound symbol' or 'sharp' (if you are a musician). :)

tamana · 9 years ago

It's a hash, not a hashtag. The hashtag is the # plus a "tag" word. When someone says "hashtag foo", they went spelling it out # + foo, they are saying "this is a hashtag, not a regular word in my setencen; the tag is foo" and the # is silent.

#prescriptivism.
