Where did they come from?

The top referring sites in 2010 were en.wordpress.com, sfml-dev.org, planete-sciences.org, facebook.com, and reddit.com.

Some visitors came searching, mostly for sfml tutorial, sfml game tutorial, sfml tutorials, sfml games, and sfml game.

The Heart Curve present

For those who are in love and (or) those who like maths, this post might be interesting. For those who don’t, be aware: this post is about maths and hearts 😉

Some time ago, I designed a heart with mathematical functions. 14th of February seems the perfect day to offer something like this. It is original, cheap and easy to do. So if you’re in a hurry and forgot to buy a present to your girl/boyfriend, take a piece of paper and write him/her down the Heart Curve.

The Heart Curve is a mathematical relation that, when plotted, has the shape of a heart. This is easily accomplished by the use of several implicit functions.

Let H(x) be the Heart relation defined on [\frac{-\sqrt{13}-3}{5}, \frac{\sqrt{13}+3}{5}], (x, y) \in \mathbb{R}\times\mathbb{R} by:

H(x) : \left\{ \begin{array}{clcr} (x+\frac{3}{5})^2 + (y-\frac{8}{5})^2 = \frac{13}{25}, & \text{if } y > x +2 \\ (x-\frac{3}{5})^2 + (y-\frac{8}{5})^2 = \frac{13}{25}, & \text{if } y > -x + 2\\ y^3 = x^2, & \text{if } x \in [-1,1]\\  \end{array} \right.

The resulting plot without using  the functions’ definitions :

Mondial des Métiers

Last weekend, “Mondial des Métiers” took place at Eurexpo, Lyon. This is a national event where people can learn about all kind of jobs in France, There’s  information about what professionals do, how they do it and how much they’re paid for doing it.

We, as the Clubelek,  participated as an expositor in the informatics field. Young people asked us a lot of questions about our “job” and what kind of interesting stuff we do. We tried to be as informative as we could, but it wasn’t easy. We’re still students so most of the time we just talked about French Universities and where to study informatics in France.

Anyway, we showed off three prototypes:

  • The robot from the French Robot Cup, 2009 edition.
  • A robotic arm that redraws in paper what you draw on-screen.
  • The robot from Project Sigma.

Resurrection

Hello there, it’s  been a while since my last update and i do apologize… well not really XD but …

I’m preparing a couple of articles so, keep tuned.

Hello world!

Hello there!

Welcome to my blog, this is the place where I’ll talk just about everything that catches up my mind.

First off, I’ll introduce myself: I’m an engineering student at “INSA de Lyon” interested in a lot of (sometimes to many) fields : programming (C/C++, Java, Python, SQL, Qt, openCV,  SFML, SDL, PHP,…), robotics, electronics, physics, maths, astronomy, music, languages, swimming and life in general. I’m blogging mostly about these, but other subjects might appear randomly.

I like pasta, however, pizza gets me bored lately… caused by eating it in a daily basis.

I’m currently working in a robotics project with a team from INSA Lyon named “Kelebulc”, we have worked hard for several months to achieve a competent robot that will participate in the French Robotics Cup from the 20 till the 24 may 2009. More info in the official website (in french). I’ll post about our robot soon.

More posts coming soon. Keep tuned.
