Les bases de la programmation Dans ce cours, j'ai tout d'abord rassemblé les notions qui m'ont semblé utiles à introduire avant de commencer proprement dit le cours de programmation. En particulier, comme la programmation est conditionnée par la manière dont fonctionne un ordinateur, il m'a semblé logique de commencer par une présentation très sommaire de cette machine : sa structure, son fonctionnement, et du seul langage qu'elle est capable de comprendre : le langage machine. J'aborde ensuite les principes d'interaction homme-machine via une souris, un clavier et un écran graphique. Le cours de programmation proprement dit porte sur les instructions permettant de rentrer des données dans la mémoire d'un ordinateur (la lecture, l'affectation) ou d'afficher des informations à l'écran, ce qui demande au préalable d'introduire les notions de variables, de type et d'expressions. Un ordinateur est une machine utilisant et produisant de l'information. Codage binaire▲ Le bit▲ Le transistor▲ Voici par exemple le zéro : Le Lisa

Free Programming Books Codea Tutorials 5 Reasons Why You Should Take a Nap Every Day I am a habitual nap-taker. I take one almost every day and have for years. I used to feel a little guilty about it—like I was slacking off or something. “Every day after lunch, I lie down on the sofa in my office,” he recounted. Napping Celebrities I then discovered many other successful people who were nappers: Leonardo da Vinci took multiple naps a day and slept less at night. Could these successful leaders know something you don’t? Are you ready to stop drifting and design a life you love? Napping Benefits I suggest you seriously consider taking a daily nap for the following five reasons: A nap restores alertness. Napping Tips I typically take a twenty-minute nap right after lunch. While working in a motor shop in college, I would eat lunch in my car and then lie down in the back seat. Here are a few practices I have found helpful. Be consistent.

Your Youth Is A Time To Embrace Patience; Don't Rush It There’s no hiding the fact that we live in a society that glorifies two words: “busy” and “now.” When asked, “How are you?” it seems that many of us have traded “Good, how are you?” for “Ugh, SO busy.” As we make our way through our 20s (and probably our 30s, too), we’re doing all we can to figure it out what we want in life. In many ways, our society has actually devalued the art of stillness and waiting. You don’t want to miss the little things. When you become swept up in anxiety about all you have to do, you stop living for the present and start living for the future, instead. You’re not done growing up. Sorry, but it’s true. You don’t want to alienate those who love you most. Stop telling everyone how unavailable you are because you just have to get X, Y and Z done. You won’t get everything done today, anyway. You’re a human, not a superhero. You can’t afford it. Don’t run yourself into the ground. You deserve to be picky. Photo via Blue Devil Tumblr
Formation informatique - VidéoNoob How to find your passion and purpose | reintegrate You may have seen a picture similar to this before about how to enjoy a purposeful life if you only focus on work in the intersection between money, talent and passion. Simple right? Well, not really. How many people do you know that are paid to live out their passion? So where and why does people stumble? Listing your talents is pretty simple. Figuring out what people are willing to pay money for is fairly easy unless you’re truly innovating but in most cases I’d think your ideas are variations on existing products and services. So then it’s just about your passion.What are you truly passionate about? This is where I stumble. Well, I’ve recently come to reevaluate my view on passion and it’s was this little video clip with Simon Sinek on how to find you passion that flipped my mental switch. Finally, the last piece of the puzzle is expressed very effectively by Seth Godin: Ship it! Seth Godin’s bottom line is “Always be shipping!” What will you start shipping? About Fredrik Lyhagen
If you’re not pissing someone off, you probably aren’t doing anything important March 5, 2014 252k shares Share on Facebook Share on Twitter Meaningful achievements are, perversely, more likely to annoy the world around you. Are you losing weight? “You should be happy with your own body!” Whatever you do, you’re going to annoy someone, and annoying someone can be a good thing. Rule 1: There are more important things than other people’s feelings One of the reasons successful people can sometimes come over like assholes is because they’ve learned there are far more important things in this world than what other people feel. It’s an uncomfortable truth. Which is deadly if you want to accomplish anything of significance. If your mission is to lead, create, or better the world, surrendering to the emotional concerns of others will paralyse and kill you. This is not to say that being an asshole will make you successful. Rule 2: Hate is a side effect of impact As your actions impact more people, the less those people will understand you: And outright distorted: Keep reading
How I Was Able to Ace Exams Without Studying Editor’s note: This is a guest post from Scott Young of ScottYoung.com. In high school, I rarely studied. Despite that, I graduated second in my class. In university, I generally studied less than an hour or two before major exams. However, over four years, my GPA always sat between an A and an A+. Recently I had to write a law exam worth 100% of my final grade. Right now, I’m guessing most of you think I’m just an arrogant jerk. Why do Some People Learn Quickly? The fact is most of my feats are relatively mundane. The story isn’t about how great I am (I’m certainly not) or even about the fantastic accomplishments of other learners. It’s this different strategy, not just blind luck and arrogance, that separates rapid learners from those who struggle. Most sources say that the difference in IQ scores across a group is roughly half genes and half environment. Rote memorization is based on the theory that if you look at information enough times it will magically be stored inside your head. 1.
