Friday Post: Conference Talk

Hey all,

For the past 2 months I’ve been heading up a small technical conference with my department.  We have done small 1 hour sessions before, but this was a lofty experiment.  14 talks, 5 hours, 2 tracks, with no budget.

It was a resounding success!  The Techrangers at UCF put on the Extended Tech Time Conference last Monday, July 1st, from 5pm to 10pm, in the Student Union.

We had over 60 attendees watch our talks while students, staff, and local companies talked about a wide variety of subjects.

We also had a Google Glass demo, which was really really cool.  Everyone seems to get “glass-face” the second they put it on.  It can only be described as getting a dumb grin, looking halfway up, and trying to focus both on whats on the screen and in front of you at the same time.  It only lasts a second but it makes for some really funny imagery.  It was tough to use it with my prescription glasses on, but this seriously makes me consider getting contacts.

13 - 13 13 - 14 13 - 15 13 - 16

I plan to have the videos up soon, but for now, here’s my talk about Gaming on the Raspberry Pi:

PiMAME

So I’ve been working for a week, trying to get this next release of PiMAME really stable.  The problem I keep running into is with DISPMANX and PiSNES/Dgen.  With DISPMANX, Dgen works, but PiSNES does not, without DISPMANX, PiSNES works but Dgen crashes.  I’m going to hold off on including DISPMANX and Dgen for this release.   The new things included in PiMAME 0.7.5 will be STELLA, the Atari 2600 emulator, and CaveStory.

This should be uploaded tonight.

Book 

So the first drafts for the book I’ve been writing came back, and they have very / minor revisions.  I’m really excited to see this project coming alone, and hopefully published very very soon.

Friday Post: Hardware

Hey All,

This week has been kinda awesome and frustrating at the same time.  We had an issue crop up at work that dealt with some legacy app, and it was a part of the system no one had ventured in for a long time.  Needless to say around 3pm today, after a whole week of digging around, we finally had a fix.  Feels good!

I sent the first draft of the first half of my book to the publisher for editing and reviews.  Feels real good!

My buddy Jacob received his Crazyflie nano quadcopter a few weeks ago and has been having a lot of fun with it.  His latest project has been to control it via a Raspberry Pi.  He has been flying it around the office and it’s a lot of fun to play with.  The thing is whisper quiet until you start turning and then it sounds like a humming bird looking for a kill is coming at you.  Again, its a lot of fun, especially with coworkers and nerf guns.

Another frustrating thing happened this week.  I needed to take screenshots of the Raspberry Pi in action playing some games, so I did some research, and it looks liked the best device is an EasyCap DC60.   This device takes input from an RCA jack and goes into your computer via USB, and appears like a webcam with the video.  It also has Mac drivers, which is a big plus.  Now I know there are a lot of fakes out there, and newer models which don’t support OS X, so I went on Amazon, looked for the proper model, and didn’t care that it was fulfilled by a third party.  It was sent via prime and said DC60.  What I got was a piece of counterfeit hardware.

Now, I buy a LOT of hardware from China.  Over the years I have been very lucky about counterfeits.  I tend to not order anything of enough importance to be counterfeited, or its generic enough that EVERYONE makes the same product.  This time I wasn’t so lucky.  I got an Easee Cap DC-60++ that used a utv007 chipset.  This chipset BARELY supports Windows much less OS X or Linux.  The software it came with was also pirated.  I decided I was going to try to get it to work first though, and see if it had any saving grace.

It took two hours but it finally displayed my video in a window.  I was so frustrated.  If you can get your hands on a genuine EasyCap DC60, its supposedly an awesome video capture device.  I’m still on the hunt for one.

 

Anyways, have a good weekend!

Friday Post: More Neat Things!

Hey all,

Another long week over here.  I’m glad we have a 3 day weekend, because I could use it.  Going to sleep until Monday I think 🙂  Anyways, onto the fun stuff!

Book

So, I’ve been waiting ages to announce this.  I have been tapped by a publishing company to write a book about a computer that means a lot to me (hint hint).  That’s really all the details I can announce at this time, but I’m very excited and eager to work on this project.

BarCamp Orlando

Last week I talked about BarCamp Orlando.  It was a lot of fun.  There were a lot of great talks given by members of the Orlando tech community.  I met a lot of cool people, and networked with some fellow educators.  It was also nice to see a big turnout of my coworkers and friends from FamiLAB show their support of this conference.

I did a talk about gaming on the Raspberry Pi, and I have to say it went fairly well.  I have grown to really like public speaking, and I am very interested in doing more.  I did about 15 minutes of explanations and demos of the Raspberry Pi’s capabilities, and another 10 minutes of QA from the audience members.

Thermal Imaged Pi

I received an email from Bux (from the forums) the other day.  He acquired a thermal scanner, so he used it to take a picture of the Raspberry Pi.

Weston  Accelerated X

A very exciting development in the continuing optimization of the Raspberry Pi has been released.  A release of the Weston software that allows accelerated X windows to be displayed on the Raspberry Pi.  This should help with the sluggish feeling that is encountered when using the GUI.  I will be testing this out over the weekend.  The instructions to install it are available here: http://fooishbar.org/tell-me-about/wayland-on-raspberry-pi/ and below:

echo deb http://raspberrypi.collabora.com wheezy rpi >> /etc/apt/sources.list
apt-get update
apt-get install weston

Stickers

I think I have sent out all the stickers.  If anyone hasn’t received theirs, please contact me again!


Have a great weekend everyone!

Friday Post: Everyone Here Rocks!

Hey All,

What a week.  I’ve been working on a presentation for the University, finally showed it off, got a ton of good jobs and awesome work.  Feels like a weight was lifted.  I don’t know if we will move forward with the idea, but it’s been fun so far.

Next week I will be at PyCon in California.  I went last year and it was amazing, and this year’s talks look great.  I’m excited.

I’ve gotten tons of feedback about PiMAME 0.6b2, and I feel like it’s going in a great direction.  If it wasn’t for all you giving me tons of feedback, this project wouldn’t be even 10% as good.  Thank you.

On an exciting note, a book I have been a technical editor/reviewer on has made it to the printers and is available to buy at Amazon.  It’s called the “Raspberry Pi Networking Cookbook”.  It’s really humbling to have my name in print, and I honestly wouldn’t have been given these opportunities without everyone’s support.  That’s why my part of the dedication is to the community.  Here’s to you!

The FIRST Robotics regional competition in Orlando has been going on this week.  I was a member of Team 108 (Go SigmaC@TS!) back in high school.  FIRST is what really pushed me into the field I’m in now, and it’s always an awesome sight seeing hundreds of students working on robots, getting excited about competition, but most importantly, making friends with others from around the world.  It’s not about winning, it’s about working together.

So wooo!  So glad it’s the weekend.  Time to sleep until Monday!

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.
