Here is a video of me singing a Brazilian song I like called “Esquadros”, written by Adriana Calcanhotto, a relatively famous Brazilian musician. I am sorry, but if you don’t understand Portuguese all you have left is my “incredible” singing skills…

“Inception” by CSE Revue
28th of September, 2010, by Cadu.I study Computer Science at UNSW (University of New South Wales), Australia, and it so happens that some awesome students of the Faculty of Computer Science and Engineering do a Revue every year. This year was probably the best one I’ve seen and the following video was played during the revue and I am glad they published it online. It is a must watch, specially if you are a bit nerd… (and no, I was not part of this Revue, maybe the next one)
Click here to watch it on YouTube.

Kidshaper 2010!
25th of August, 2010, by Cadu.In a couple of hours I am going to Melbourne to attend Kidshaper 2010!
I can’t wait to learn from all the guns who will be speaking, hang out with Michael Chanley again (the cmconnect master!) and to have fun in Melbourne with my awesome friends.
If you live in Australia, work with kids and you didn’t register for it this year, make sure you do it next year, because it is a great conference.
Time to go…

I’m bored!
20th of July, 2010, by Cadu.I happen to talk regularly to a few preteens during the week, and one thing that I hear a lot from them is that they are bored. Every time I hear then complaining about it I feel sad and think “But how? How can you be bored??”. I don’t think I ever felt like that when I was a kid or a preteen. Seriously, this often bugs me so much that I try to remember how I felt when I was bored, and I am never able to remember a time when I felt like that…
Even though I have a sister, I used to spend a lot of time on my own, and when I was not playing with her I always had something to do. And when I didn’t have something to do, I invented something. I never had a video game (until two years ago when I bought a Nintendo DS)… but I had a chemistry set; I liked to do experiments with plants and insects; I took an electronics course by mail; I played with matches and fire; I looked at my own sperm in the microscope (too much information perhaps, but still interesting); I learned BASIC; I tried to make a rocket (that turned out to be more like a fragmentation grenade that thankfully didn’t explode) and tried to make trinitroglycerine with a friend as crazy as me (which also didn’t explode, very sad…); I learned sewing, counted cross-stitching and knitting; I opened (and never closed) electronics and toys (and sometimes made something new from their spare parts); I recorded funny things on tape; I made some short films (and I didn’t have YouTube to publish them); and when I ran out of things to do, I found new ones…
Sometimes I try to compare their times with my times, and it looks to me that they have more alternatives to “waste” their spare time than I did years ago. They can do everything I could do, plus all the games and entertainment that is available today. They can even learn Python instead of BASIC! And yet, they are bored…
While I have some theories to explain why this is happening, I don’t have a concise explanation. Sometimes I think that all the technology and entertainment options available today is the reason why they get bored so easily, but I might be wrong. And that is where you come in to the discussion! If you have any ideas, any theories that could explain it, please say so in the comments… or if you read any recent research paper on this topic, please let everyone know about it! Also, if you have a solution for it, I will be very happy to know it!
I will probably write another post on this topic in the future, hopefully with more answers than questions.

Two great lessons…
3rd of May, 2010, by Cadu.It is the 3rd of May, and I missed the opportunity of posting something yesterday (the only day of the month which is prime and even). Nevertheless, today is also a prime number day, and I shall post something before the spiders decide to move from my house to my blog and fill this place with spider webs…
First I would like to apologise for the lack of posts. And now I would like to inform you all that I moved! I really don’t like moving houses, but hey, now I live in Coogee, 3 blocks from the beach, and the photo above I took this morning while reading my Bible and having breakfast (sitting on the sand, at the beach). Isn’t it awesome?
The not-so-awesome part of all the moving thing is that I have so many things yet to be organised and cleaned. I am also trying to stop doing nothing while I should actually be studying maths, otherwise I will fail again this semester, and this is not something I desire. In addition, I am working on an iPhone (and Android, of course) app that will soon (at some point between today and next decade) be announced and fill you all with wonder and excitement. But that is all I can say about the app for now. 
This means that if I fail to post on prime number days, please don’t eat me alive for at least two reasons: 1) I think I don’t taste good; 2) I have good reasons for it… 3) if you find a third one, write it on the comments! 
But to not post something useless, I will teach you two important lessons, one regarding maths, and another one regarding life. Let’s start with the most important one (or not):
Did you know that any integer greater than 1 can be written as a factorization of prime numbers? Not only this, each number can be written as a unique product of prime numbers (not considering the order of the factors)! For example, 25 = 5 x 5; 192 = 2 x 2 x 2 x 2 x 2 x 2 x 3; and 100 = 2 x 2 x 5 x 5. Isn’t it awesome? This is called the Unique-Prime-Factorization Theorem, and it is the Fundamental Theorem of Arithmetic. See, now you know…
The second (and probably more relevant lesson): If you ever have a problem with someone, please choose one of two options (or both): 1) talk to a good friend about it just to get the problem out of your mind and then pray for the person and forgive him/her; 2) or if it is something you should do something about, talk directly to the person you have a problem with (after praying and/or talking to a good friend might help), and solve the problem. Do NOT talk to other people about it in an useless attempt of fixing the problem. This is not only idiotic and foolish (ie. totally unwise), but it will make everything worse. I am not very old, but I can tell you this advice is true and good by (lots of) experience (and the Bible says so; it must be true).
That is it for today… I love random posts!
