What I’ve been up to?

LMAO, What a Mistake!

I’d gotten a “spam” (not totally, I found some real great deals from them) Email from TigerDirect.ca today and I really couldn’t help myself from LOL.

A Math Problem and the Answer

jaux — Mon, 28 Apr 2008 02:38:47 +0000

Problem: Two prime numbers (>=5) and there are one and only one number between them, such as (5, 7), (11, 13), (17, 19), etc.. Prove the sum of such two prime numbers can always be divided by 6.

Answer: All the natural numbers can be expressed as 6n+0, 6n+1, 6n+2, 6n+3, 6n+4, 6n+5, n >= 0. 6n+{0,2,4} are all even and 6n+3 can be divided by 3, so they are not prime numbers (2 is prime, but the problem is asking prime >= 5, so we ignore 2 here). Therefore, prime numbers can be only in two forms: 6n+1 and 6n+5.

Let p1 = 6n+5 and p2 = 6(n+1)+1, there is only 6(n+1)+0 between them, which satisfies the constraint in problem description. Then, p1 + p2 = 6n+5 + 6(n+1)+1 = 6(2n+2) which obviously can always be divided by 6. Note that p1 and p2 can be any two natural numbers satisfy that constraint, therefore two prime numbers. This example concludes our proof.

Checkbox! For what?

jaux — Thu, 03 Apr 2008 00:06:13 +0000

Update: tombyong informed me that those checkboxes were gone about 2.5 hours after this post. Thanks, tombyong!

When I logged in my iGoogle today, I immediately spotted a change in the Gmail gadget: There is a checkbox sitting beside each Email title!

IMAGE IS MISSING, SORRY!

When I saw these checkboxes, I thought the Gmail gadget would finally add “Delete” and/or “Report Spam” features, so that I could do “More Actions” right within my iGoogle. But After searching and searching around the gadget, I couldn’t find any new feature out there…

So, what are these checkboxes for? Is it a mistake or is anything new undergoing there?

The Fact Is …

I haven’t updated my blog for a long time, no excuses for that. I’m not sure this blog even has a single reader, so if you’re waiting for update for a very long time, I would say I’m really sorry about that. But I’m back now. From now to May 2009 is the last year for me to be an undergraduate student in the University of Waterloo, I’ll keep updating this blog to record something, well, something …

OK, let’s get into what I want to say today.

As you know, or maybe you don’t know, there is a big bad thing going on in Tibet. Many people in the rest of the world don’t know the truth of Tibet problem in China, because some “anti-China” media like to mislead people, I guess. So, if you want to hear some voice from inside of the country, please watch the video:

I know it’s not new, but I just can’t stop laughing whenever I watch the video.

Wow, a fatter Gmail!

But I lied you in the title, do you find that? It’s not equal, but almost. ;)
