Babies!

by Mr. Pelletier

Welcome back to school everyone!  I’m so excited to have you all back in my classes.  Thanks for waiting for me; I’ll be back in October.  In the meantime I am so pleased to have Ms. Braaten take over as teacher for our classes.    In the meantime, here are some pictures of my little ones, Miles and Ryan Pelletier!

Here I am with the boys!  Dual wielding was always my first choice in RPG skill trees.

The boys battle for supremacy   Vicious groin kick from Ryan!  Atta boy!

Feeding and taking care of the little ones takes Susan and I 12 hours out of every day.  Here I am helping Ryan to burp.

The boys were born quite premature, at 33 weeks instead of 40.  So, they needed some help along the way.  Here is Ryan in his spacepod incubator.  I am concerned that as a side-effect of this blue-light treatment he will be biased towards playing Protoss.

And that’s it for now!  I’ll try to post some better pictures of their faces and stuff.  Fatherhood has been a powerful experience.  It challenges you on every single level, especially because our boys were born quite premature, so there have been some health complications and therefore many sleepless nights. But it doesn’t even matter … it’s amazing how quick you would do anything and everything for these little people without a second thought, who were not even in your life just 2 months ago.

Enjoy your September everyone, and we’ll see you in October!

14 Ways To Contribute to Open Source Projects (For Beginners!)

by Mr. Pelletier

Open Source Logohttp://www.softwarequalityconnection.com/2012/03/14-ways-to-contribute-to-open-source-without-being-a-programming-genius-or-a-rock-star/

Sometimes students ask me what they can do to get involved in open source projects.  This article has some great ways to get involved, even if you aren’t a compsci grad yet!  I would strongly advise students thinking of going into computer science to start getting involved in a project like these.  The experience you gain from participating and the contacts you make while doing them can give you a big advantage in the future.

World’s Fastest Computer

by Mr. Pelletier

The Japanese Supercomputer known only as “K” has the world record for most calculations per second, hitting 10 quadrillion calculations per second (10.51 petaflops).  According to the artilce, “the supercomputer “K” consists of 864 racks, comprising a total of 88,128 interconnected CPUs and has a theoretical calculation speed of 11.28 petaflops, the companies said.” What do they use this beast computer for?  Mostly for very realistic simulations of the real world, such as weather patterns or how materials behave under different conditions.  But, I suspect the engineers are playing Crysis every night on maximum settings.

 

Also notice it is powered by Pylons.

Steve Jobs Passes Away

by Mr. Pelletier

“Remembering that I’ll be dead soon is the most important tool I’ve ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure – these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.”

-Steve Jobs (1955-2011)

Can You Guess What This Is?

by Mr. Pelletier

This is a hard drive from 1956.  It weighs 1 ton and stores 5mb.  This really makes me appreciate my 16gb memory stick I carry around in my pocket.
