HTML5 Revisited

Besides canvas, video and audio tags, HTML5 can find out where you are with Geolocation and you can start a thread to do background computation with a Worker.

This codediesel site is VERY nice.

It can even do Sockets, check this out: http://websocket.org/echo.html.

Now HTML and Javascript is not so separable.

Modern web developers should at least heard of most of the HTML5 elements. Oh my, that's also an excellent page.

But the problem of HTML5 is still not all browsers support everything.

Gender Gap in Math

The verdict is this: There isn't a gender gap in math learning. See details here.

This means boys as well as girls can do well in math. Absolutely! What does gender has to do with it?

Female students can take any math class they like. No one is restricting them in American universities. Alas, look around the math classroom beyond the required basic classes. You will find mostly guys, especially foreign student guys. If math majors want to find a Miss Right in the classroom, probably should consider taking classes in nursing or elementary education and secure your Miss Right first then switch back to math.

Americans need not to worry too much about gender gap of advanced mathematics... work on the basics first! Ranking 25th in the world isn't something to be proud of. Come on America, yes we can.

There is no gender gap. Mom and Dad both learn that easy elementary school and high school math please! Mom and dad teach your kids please. Don't rely on the teachers alone.

2012

Happy Holidays, Happy 2012.

MANY people are killed over the holidays. See here and here for violence in Chicago alone.

As people party over celebrating the earth returning to an rather arbituary position relative to the sun, violence sometimes result. Every year we see sad story like this: a kid got shot by a new year celebration bullet shot in the air. See here.

There should be legislation BANNING shots firing in the air! These equations are deadly!

Instead of needed legislations, we have the following:

1. Already Expensive Parking Meter Increase!
Details here

2. Seat belt in back seat required
Details here.

Ticket them for talking while driving! Ticket them for texting while driving! For that endangers other cars and pedestrians. Car makers to provide seat belts, sure, and they have done so. Cops ought to have better things to do than checking rather people have seat belts on.

Don't terrify your kids in Christmas

Kids are afraid of Santa.

You get in lines to get your kids scared by taking them to take picture with a fictitious character? how silly is that. Besides Santa, kids are also afraid of big dolls their size or strangers (don't bring them close to your rarely-ever-visit friend)

Ok, when your kid gets older that won't be a problem anymore.

Merry Christmas to those who read/subscribe to my blog.

2012 predictions

Election 2012
With no obviously-better-choice-than-the-incumbent Republican candidate, I predict Obama will get re-elected!

Tech
Android and iPhone will continue to battle with no winner needed. They can co-exist (like Apple and Microsoft coexist in desktop for decades). In the phone market, I am afraid Microsoft phones will be like Palm Pre. Microsoft Windows and Windows desktops will completely dead if people can do everything with their Android/IPads. But that day isn't here yet! The pads need a file system (like c:\mystuff) and an Office Suite at least. Otherwise pads will just be a portable browser and that can just run little apps.

World Events
Now that's hard to predict. Conflicts will continue and I just hope US is not going into another war. All these people worrying about China dominating militarily will prove to be like the ancient Chinese story of a man scaring of the sky collapse onto him. I hope to see: the new young leader of North Korea will learn a thing or two about its neighbors and at least reduce the famine in that country.

Higgs Boson
I do NOT predict the Higgs Boson be found in 2012 despite huge expensive machines. It does not seem to be easy (otherwise people found it long ago). All that to explain a fairly basic question, "why do things have mass".

2012 is not the end
I predict there will be 2013, despite the Mayan doomsday prophecy.
