Windows 7 new trick discovered

Yes I still use Windows 7 at work.... and am glad not using Windows 8, or the Mac. Gosh I hate the Mac though I don't mind its Unix prompt. Without that it is even more unusable.

Alt-Tab to switch between things has been there for ages. Since Windows 3.1. One day I tabbed on the Windows-button instead of Alt. Oh wow, I discovered a new way to switch apps and it is called Flip3D.

See here

This is probably not on Windows 8 as this is Aero.

Now that flat interface of Windows 8... according to some stuff I read is a battery saving feature for laptop and tablets as it is expensive to show half-transparent things in the title bar. Ok I buy that. But this isn't issue for computers plugging in all day. Windows 8 really should give people an option to use Aero... see you spent so much time and money to develop it and you just throw it away.

Another note: that image above has that Windows 7 Gadget thing... sure is neat idea (basically a window less program). But the world just abandoned it due to security issues. See it here. But why can't it be fixed and just abandoned? Well but the wacky Windows 8 Metro (yes I refuse to call it Modern) don't need the gadgets to live on desktop as the entire Desktop is kinda going away for its wacky titles.

Looking forward for Windows 10.

Stop calling people 'dorks'

The π moment of the century has came and gone. Saturday was a special π day. March 14, 15. The moment was 9:26:53 to spell out the first 10 digits of π 3.141592653.

There were numerous articles talking about this and plenty of pies made decorated with π.

Plenty of journalists needing ideas to write wrote about π these days. Most give you a review of the definition of π and that's about it. And you really are uninformed if you need someone to remind you that. Few go any deeper.

This one I like as it gives you more fascinating info. http://theconversation.com/pi-day-is-silly-but-itself-is-fascinating-and-universal-37948.

While yes, it may be silly to eat pie on π day just like eating something that starts with 'e' on Earth Day, I don't see anything wrong with that either.

I am especially not happy with this one: http://www.businessinsider.com/once-in-a-century-pi-day-2015-3 Just who are you calling dorks?

If you have no respect for people you aren't going to get respect.

See, the fact that the π day gets people some attention to math is already worth it. Is there something wrong with eating pies over there?

Oh look there is some interesting thing about math. There is this number that is impossible to complete grasp (write down) and that is in every round thing out there. There is another fascinating number that you can simply make out by sliding a square in its diagonal. That square root of 2 is another irrational number that can't be entirely written down either. (Yet nobody celebrates the square root of 2 either by eating triangular pies).

Most people are too shallow to know another thing about π besides maybe mixing up 2πr and πr2, area of a circle. Most have no clue how you get π=C/d to the area formula = π r2.

How unfortunate.

A better education helps. Although you may think it is absolutely ok not to know anything about it. (It is absolutely ok not to know anything else too)

Some people got tricked by their (clueless) math teacher in elementary school thinking π is exactly 22/7. How unfortunate.

When I was in elementary school I immediately pulled out my calculator and found out it is 3.142857 not quite the same as 3.1416. 22/7 is just an estimate (and a fairly good one). I already wondered: how the heck did you get 3.1416? And I thought people may have ultra good measuring device to measure circumference over diameter to get that. And when I found out π is cranked out in millions of digits I decided to find out how they do it... This itself is already a great topic to explore.

Speaking of approximation of π an ancient Chinese mathemtcian came up with 355/113 but I don't think anyone knows how he get it. Writing down steps of proof just wasn't properly practiced back then.

We should be humbled by gosh there are so many pieces of knowledge out there. And only when we are humble we can learn a thing or two. Mocking others do not get you anywhere.

Stop calling people dorks. That author owes me and every math enthusiasts out there an apology.
