IEEE Raspberry Pi talk

I was invited by Dan Bishop to speak at the IEEE meeting for July 10, 2014. It was fun to talk about something Raspberry Pi and Linux. I’ve loaded the file to my Google Drive, but anyone can download without logging in using this link (download a copy). Feel free to modify, comment or send me email.

Mintcast episode 176

If you get a chance, have a listen to the Mintcast podcast # 176. I posted a comment on their Google+ page about episode 175 (and it was read on episode 176) WOOHOO!

Howdy Rob and Scott,
This is in regards the PiBang episode. I’ve been listening to the show for quite a while now, but I can’t remember when I started listening. I know it was sometime after I moved away from Ubuntu to use Mint. I may be biased a bit because I run Arch on one Raspberry Pi, my laptop, XBMC server, and Ampache / minidlna music server. I’ve made converts of several co-workers too, but you should use what you feel comfortable with: choice is a beautiful freedom.

I have to argue that Arch Linux ARM is less complicated to install on the RaspberryPi (RPI) than Pibang based upon all the stuff you had to go through just to get it close to a functional system for ssh access. Just download the image from, and follow the dd process (carefully I might add). One thing that you want to do is expand the root partition. I eject the sd card, pop it back in and run gparted to perform that action as I know it will be done correctly. Follow the next guide to find the IP of the RPI and ssh directly to the pi as root – . Alternatively you could use an nmap command to search your network for the RPI (sudo nmap -sP and you should see it on your network as “Raspberry”

I’m using Arch on my main model B (256mb model) RPI as an ssh gateway. I run sshguard with iptables to keep most of the riff-raff at bay. You see, I must use port 22 for access from certain locations where I originate an ssh connection. Security is raised up to the highest using PKI keys and really makes for entertaining reviews of the auth.log. I see crackers from all over the planet attempting to get to my seemingly valuable little RPI.

My model B revision 2 (512mb) acts like an access point, runs Raspbian on a 32GB class 10 micro-sd via adapter card and acts as a Time And Relative Dimension In Space media box – i.e. I have a battery and a small TARDIS (Yatzee dice case) in which I place the RPI. The purpose you might ask? Well it is totally for fun! I have both minidlna and bubbleupnp server installed. That way I can connect a speaker or head phones, though the RPI leaves something to be desired as far as quality sound output, and stream music directly from my bubbleupnp client on my phone. Alternatively I open and play the media stored on the RPI that is presented via minidlna either as output on my phone (works for video and pictures as well) or direct audio out the RPI connected spearkers.

My other model B is mainly is as an XBMC media server running OpenElec 3.2 (or later). XBMC runs so well with and it even has bluetooth and full wireless configuration tools built into the OpenElec add-on that comes in the package. My wife uses this RPI at times to watch streaming videos on the old CRT TV via VGA converted to 75ohm Coax (and an old channel 3/4 switch) and she controls it with her android phone and Yatze.

I know this was a long post, but it was my first.
Keep up the great job. Its great to hear you guys discuss what matters to us geeks.

Webcam pulse detector

I found this on G+ just now… Amazing what you can do with python!

A python application that detects and highlights the heart-rate of an individual (using only their own webcam) in real-time. Touchless pulse measurement.

What do you think of the new theme?

Sure you can’t post comments – not yet, but I’m working on it. We had a rash of bad posts long ago from multiple spammers and I had to disable posts and even membership to this site. Since the wordpress upgrade, I’ve noticed many great plugins to all but eliminate these bad actors.

Raspberry Pi in qemu

Want to test your RaspberryPi Distro? In my case I tested the wheezy-rasbian, but you can test others like archlinuxarm, openelec, etc. Simply replace the image file with that of your choice. I normally cd to the directory holding my RPI images and run the command from there.


Just install qemu then issue this command as a user:

qemu-system-arm -kernel kernel-qemu -cpu arm1176 -m 256 -M versatilepb \ 
-no-reboot -serial stdio -append "root=/dev/sda2 panic=1" -hda \ 
Posted in new | Leave a comment on Computer America!

I sent a short email to Larry and Tom from the Going Linux podcast (back in April 2010) and it got airtime on the live radio show Computer America. I was listening to Going Linux podcast #103 and heard M.G.A.L.U.G mentioned as the first email in the listener feedback section. Wow!

Go have yourself a listen and welcome to those listeners who decided to check out our site. If you happen to be in the area the 3rd Saturday of any month, stop by between 2-4pm at the Atlanta Bread Company in Warner Robins, GA and say you heard about us on the Going Linux podcast.

Use a Linux CD For Banking

That’s what the Washington Post says in this article.  Of course Linux users have known Linux was safer, and now the rest of the world knows.

Linux – Stop holding our kids back!!

Dec 9, 2008, 17 :05 UTC
What follows is a blog posting from Helios’ blog…

When will our Educators Learn?


“Mr. Starks, I am sure you strongly believe in what you are doing but I cannot either support your efforts or allow them to happen in my classroom. At this point, I am not sure what you are doing is legal. No software is free and spreading that misconception is harmful. These children look up to adults for guidance and discipline. I will research this as time allows and I want to assure you, if you are doing anything illegal, I will pursue charges as the law allows.

Mr. Starks, I along with many others tried Linux during college and I assure you, the claims you make are grossly over-stated and hinge on falsehoods. I admire your attempts in getting computers in the hands of disadvantaged people but putting linux on these machines is holding our kids back.”This is a world where Windows runs on virtually every computer and putting on a carnival show for an operating system is not helping these children at all. I am sure if you contacted Microsoft, they would be more than happy to supply you with copies of an older verison of Windows and that way, your computers would actually be of service to those receiving them…”  Click for the Complete Story

Dell & Ubuntu

Dell is selling more Ubuntu desktops and laptops! If you want a good system, check Dell’s lineup. I use Dell systems and as consumer systems go, they rank quite high for a Linux box. You get support from Canonical, the parent company behind Ubuntu.

Penguins can fly

Yet again, don’t we all wish we could fly? Linux gives us wings…This Video was on Youtube for a while. It is a  mashup of the April 1, 2008 BBC joke.  You would be able to enjoy this on Youtube, but they are a bunch of babies, caving into the BBC and other groups out there.

This video was removed due to “copyright violation”, though it is fully covered under the fair use doctrine as it is a parody or mashup of the original work. The video is available upon request at our LUG meetings. You can also find it elsewhere on the web if you search long and hard.

Bluetooth is a wonderful technology when it works. I have been using a laptop with built-in Bluetooth support for over 5 years. I’ve upgraded from a tiny IOgear mouse to a Microsoft bluetooth travel mouse 5000. Having internal bluetooth makes perfect sense when you want to protect your valuable USB ports from damage and the cost is nominal and usually around $25. You also get the benefit of having empty USB ports for other things like a light, fan, or USB memory sticks.

I’ve also paired my Nokia BH-503 bluetooth Headphones, which produce high-quality stereo right along side the mouse with the same bluetooth chip and have no lag in either one. This goes for my Apple bluetooth keyboard I won in a contest. All three devices on one connection without lag… pretty cool, huh?

Using these features is about as simple as SuSE was, but can be done in the GUI from the system status area. Just enable your device to be seen, click the bluetooth icon, setup new device from the status tool and in about 20 seconds and a PIN (Ubuntu can even provide the correct one for you) & you’re ready to party! Yeah, there’s one more trick to getting stereo, but that involves selecting that option from the Sound properties menu, again found in the system status area. You can even use bluetooth tethering with cell phone for data transfer as well as web access. Continue reading
