Was posted on HN a few weeks ago... still upvoted because it's great :)

What set of books or resources would you recommend as a good introduction to this trifecta of technologies? (HTML5/CSS/Javascript)

Mark Pilgrim's "Dive into HTML5" book draft:

http://diveintohtml5.org/

ppk on JavaScript:

http://www.quirksmode.org/js/contents.html

Mozilla's documentation:

https://developer.mozilla.org/en/HTML/HTML5

CSS3 Preview:

http://www.css3.info/preview/

HTML5 draft specification:

http://www.whatwg.org/specs/web-apps/current-work/multipage/

Much obliged; thank you!

There's http://diveintohtml5.org which I don`t believe is 100% completed yet. I guess it's still too early for a comprehensive book - HTML5 is still in draft mode.

Didn't stop people from writing PHP6 books ;)

Worked well on Safari. But this was funny:

"Chrome Frame Minimal effort for bringing IE6, 7 and 8 up to the latest HTML5 technologies"

I loaded it up in IE8 and chose not to use the chrome frame. The presentation returned a javascript error and nothing at all to read. Just a blank page now in IE 8.

This stuff is awesome, but what sucks is I fear that it's going to be way too hard to convince people to install something called a chrome frame to view the stuff they want. Although it was once that way with Flash, so maybe history will repeat.

In other words, a Snappy Chrome Demo:

(from the disclaimer)

The presentation was originally meant to run in Google Chrome. Some experimental features might or might not be coded to run in other browsers for now.

Darn, it crashes Safari on my iPad. Ironic given that the iDevices are the ones providing onus to developers to use HTML5 in the first place. /-:

Works pretty well on my iPhone though. It totally breaks the back button, but I love that I can swipe left and right to navigate.

Wow, really? I didn't realize you could swipe in this presentation. Looks like this was all it took to implement?

  var addTouchListeners = function() {
    document.addEventListener('touchstart', function(e) {
      touchStartX = e.touches[0].pageX;
    }, false);
    document.addEventListener('touchend', function(e) {
      var pixelsMoved = touchStartX - e.changedTouches[0].pageX;
      var SWIPE_SIZE = 150;
      if (pixelsMoved > SWIPE_SIZE) {
        nextSlide();
      }
      else if (pixelsMoved < -SWIPE_SIZE) {
       prevSlide();
      }
    }, false);
  };

Try rotating. That reliably crashed Safari on iPhone and iPad for me. If it hadn't crashed for some other reason. When it didn't crash it did strange things like display things from later slides on the first slide when it was loading.

Hopefully some geeks at Apple have seen this and are already fixing bugs that it uncovers.

This is slow as hell. I do not understand why people think HTML5 can replace Flash. Flash is big and bloated but still perform better than HTML5 in all the so called demos i have seen.

What browser are you using? I've tested it on Safari/OSX and Chrome/Windows, and it was perfectly fast and responsive, even on a three-year-old budget laptop.

I was using Chrome and found it surprisingly speedy. At the end, I was able to whisk from slide to slide faster than I generally can do anything on my computer.

Wasn't that slow for me on my netbook, but doesn't have any scrollbars, which meant I couldn't see a large part of the bottom @1024x600.

Give it time. And it is not suppose to replace flash, just greatly reduce its scope.

This consistently crashes Epiphany.

Breaks the back button.

how the hell can they find my exact location?

How exact are we talking? IP Geolocation has been around a long time, but isn't very exact.

Are you an Opera user? They have links with the Skyhook WiFi access point databases to locate people (like the iPhone 2G does) - http://www.opera.com/press/releases/2009/03/26_2/

Alright, I figured it out. They go through the data collected by google through the street view car: http://googlesystem.blogspot.com/2010/04/how-google-collects...

That's the only way they can know the coordinates of were I live since it's a residential area and the only wifi I see are mine and the two from the neighbors.

The block were I live! I am on a netbook (wiki) with chrome, no GPS.
