Here's a ‪#throwbackthursday of my grandpa back in the late 50's. He's on the left in the picture, and was the fire chief of Brockway, Pennsylvania for 10 years.

Here's an update on my drone App I'm working on.  No fly zones are marked with 5 mile radiuses around airports.  Here's a quick overview of some of the features added so far, but there's still a lot of work to be done:

 - Directional markers (in blue) indicate nearby flight hazards, including airports, helipads, balloon ports and seaplane bases.  I plan to include others, such as stadiums, schools, hospitals, etc as popular places to avoid.
 - The map works standalone so you can pan across to view other areas as well, and also as a compass so you can see nearby hazards more efficiently.
 - TFRs are pulled from the FAA announcements page and displayed within the App.  The shape data is not rendered to the map yet, but it is being worked on.
 - Flight Logs are being added, so you can keep track of all the important information regarding your flights.  This may be useful for future licensure, if the government should require it.

Howdy all!  I need some help.  I want to interface my RPi with an A050FW03 LCD / Touch Screen module that I salvaged from an old TomTom GPS.  Unfortunately, all of the driver boards I'm able to find are for 40 pin versions.  Does anyone know where I can find a 50 pin driver board, similar to the RA8875 (https://www.adafruit.com/product/1590) that will work with my Model B?

I have the pinout for the A050FW03 from it's docsheet.  I just don't know that much about these types of connecters to wire up my own step-down adapter.

Can anyone provide a simple example on how to use vDSP and Swift with the AVAudioEngine installTapOnNode: to perform forward FFT on the audio buffer?  I'm trying to get this working, but it seems that Swift doesn't like it when I try casting the sample array of Floats as a COMPLEX type.  I think if I had an example to compare to, I should be able to get my code working.  Thanks!

For reference, I am using this as a guide to learning FFT and vDSP, and attempting to convert it to Swift: https://www.mikeash.com/pyblog/friday-qa-2012-10-26-fourier-transforms-and-ffts.html
Last time around I discussed the basics of audio data, how to get it, and how to understand it. Today, I'm going to go into some detail about one of the fundamental tools for more complex audio analysis, the fourier transform, and the FFT algorithm that makes it practical to use on computers.

Finding some more time to work on the DBMS system I built for my wife. Still a long way to go, but I'm think it's starting to head in the right direction now. This is entirely hand coded and built from scratch.

What do you suggest for making a linux installation to be "kid friendly"?  I have an LXLE install on an old i386 (lubuntu based, 12.04), and it's specifically for 2 young children to play games and learn on.  I've tried installing Nanny from the repo and the test ppa, but neither seem to work (crash when launched).  Any good educational games for young children?

I read about GCompris http://gcompris.net/index-en.html
Have not tried it though

Never ran across this problem with a VM before. It's just booting to a LiveCD, then the graphics go to hell after X starts. If I press ALT+CTRL+FN+F1, I can drop to the terminal, and then ALT+CTRL+FN+F7 will bring be back into the X session and force the kernel graphics buffer to reload. This seems to get me to a working X session so I can proceed to install on the VM, but does anyone know why this is happening?

I've got AVAudioEngine working great, and I'm starting to apply FFTs to the buffer data to build a frequency visualizer for my latest App.  Needless to say, I have a sudden appreciation for those who work with FFT, haha.  I keep pushing forward, though.

Syllabus day (as odd as that may sound) ... Feels like the semester is nearly halfway over and yet this class is just starting.
