Friday Post: 2600 The Hacker Quarterly

Hey All,

I have been keeping this tightly guarded for about 6 months now and I am VERY EXCITED to announce that an article I wrote entitled “Hacking, Learning, and the Raspberry Pi” has been published by the 2600: The Hacker Quarterly.  The spring was released today and it is very exciting seeing my name in print.

To me, this achievement is akin to an academic researcher being published in a journal.

2600 is an amazing periodical with a long history, large following, and amazing reach.  From Wikipedia: “2600: The Hacker Quarterly is an American publication that specializes in publishing technical information on a variety of subjects including telephone switching systems, Internet protocols and services, as well as general news concerning the computer “underground” and left wing, and sometimes (but not recently), anarchist issues.”

I’ve been reading 2600 ever since I found it in a bookstore back in high school.  I never thought of the word hacker, or hacking, as anything bad.  It was to me just a kid being curious while using a computer.  2600 solidified that feeling for me and many people in the computer industry have felt the same way.  Most of the companies I have worked for even had a subscription because the information is just that valuable.

You can pick up a copy at your local bookstore, from the 2600 Online StoreAmazon Kindle, or Barnes & Noble Nook.

Thanks for helping make this possible!

Saturday Post: PyCon 2013 Redux!

Hey all,  hoping not to make [Saturday Posts] tags a habit but I feel bad that the wireless ate my last post 🙁

So PyCon is going amazingly well.  I have seen some amazing talks,  I gave a small talk about PiMAME for 15 minutes in the Raspberry Pi lab.  Everyone who attended got a free Pi.  Sourceforge told me they could easily host my PiMAME images so that’s a plus for everyone here.

I got to hold (but not wear) a Google Glass.  It feels incredibly solid.  Light.  Balanced.  I’m excited for it.  O’Reilly was giving out a ton of books, and I have my reading for the next year scheduled.

A lot of the attendees  were impressed with PiMAME and I’m excited to get the next version out.  I’m brain fried.  I will have pictures and things and stuff to post when I get back to Florida on Monday.  Woo!  PyCon!

PiMAME code on GitHub

Hey All,

I’ve put my PiMAME code and configurations on GitHub for anyone to look at, check out, fork, make improvements, etc, etc.

If you check out menu.py,  you will see that I have a new line item for RetroPie / EmulationStation.

I am testing it out in addition to AdvanceMAME.

Enjoy!

Book Review: Python For Kids

Hey All,

I met No Starch Press at PyCon 2012 where they were showing off chapters of their then upcoming book, Python For Kids by Jason R. Briggs.  I was talking to them and expressed interest in getting a copy for the students in my department at the University.  At the end of December the book started shipping and No Starch was kind enough to contact me and send me a copy.

I have to say that I think the book is great.  It has 18 chapters and is around 300 pages, with the book split up into 3 parts.  The first part is an introduction to Python 3, the syntax, as well as standard programming conventions like loops and variables and functions.  It also goes into modules, turtle graphics (like the LOGO language of old), objects, classes, and the tkinter GUI library.

The second part gets to the fun activities you can do with Python like programming games!  All the chapters in this part of the book are about using tkinter and Python to make a pong / arkanoid like game and it walks you through every step of the process.

The third part of the books builds upon the previous game, and teaches the reader how to make a simple platforming game, complete with sprites, animations, and events.

I REALLY liked this book.  I tried to read a chapter a day, and I kept having to stop myself because I would say just one more chapter tonight… (I like to pace myself).  I feel the author really captures what a kid would like to learn about and presents it in a manner that will keep them entertained, motivated, and interested.

I do have two very minor nitpicks about the book that stayed with me while I was reading it.  The first one was the lack of explaining types.  The author dives right into strings, and ints, and floats, but doesn’t explain what the difference is between them, or why you would use one over the other.  I think a simple introduction and type chart  would have made the first part a much easier read for a beginner.  The second nitpick* is that the last part of the book ramps up the difficulty.  You do get a finished game out of it, so the challenge isn’t for nothing, but I still found it to be a bit jarring after breezing through my reading of the earlier chapters.

Barring those two very minor issues, I think this is a fabulous book.  For a programming book, it is on the inexpensive side, at around $20, and packs a good amount of material for the price.  I recommend it.

*A good friend of mine told me that I’m not looking at this one through kid glasses.  They would probably have no issue with the difficulty ramp up, and would in fact welcome the challenge.

Friday Post: Baked Raspberry Pi

Full Disclosure: Seeed Studio sent me the Wireless Charging Module for free because I entered their reviewer contest.

Hey All,

So I said I had some cool hardware to show off today, and here it is: Seeed Studio’s Wireless Charging Module

photo (1)

This kit uses inductive charging to transfer power “wirelessly” from one coil to the other.  You put in 12v 1A on the transmitter end, and on the other end you get 5v 0.6A.

I initially had some trouble getting it setup.  I was trying connectors in every different position, every combination I could think of.  It took me a day to realize my power supply was set to 9v rather than 12v.  Once I upped the voltage, I could hold the coils an inch away from each other and still keep a charge.  I also tried putting things in between the coils to see how much interference it could take.  It had no problems with a coupon book, business cards, a small plastic mint case, though it did have issues being between a remote.

Now, me being me, I had to try this with the Raspberry Pi, and I knew I had to do something special.  My coworker Mike has been fiddling with bare metal assembly on the Pi, and has ported NyanCat to the system.  His github repo with the source assembly code and pre built binary is available here.

By connecting the receiver coil to the 5v and GND GPIO pins, I was able to wirelessly power the Pi.

I hope you enjoy!

Have a great weekend!

PiMAME 0.5 Beta Release

Hey all,

This is just for testing purposes, but if you like to live on the cutting edge, I’m making available the beta/pre-release/testing release of PiMAME 0.5!

It’s based off the PiMAME 0.3 image, with the Uploader file size limit set to 200MB, and the Snapshot artwork in AdvMENU.

Let me know if you have any issues with it!
