Beagle Bone Black Static IP
Static IP Address under Debian
According to Derek Molloy’s website it is easy to set a static IP under Debian: http://derekmolloy.ie/set-ip-address-to-be-static-on-the-beaglebone-black/
[Updated April 2015] To set the IP address to be static under Debian is quite straightforward. You can simply alter the /etc/network/interfaces configuration file to manually specify the address (e.g., 192.168.1.80 in this case), the network mask, and the network gateway. Use an editor, such as nano, to edit the /etc/network/interfaces file and For example, the settings for my network, which has a common configuration, are as follows: molloyd@beaglebone:~$ uname -a
Linux beaglebone 3.8.13-bone70 #1 SMP Fri Jan 23 02:15:42 UTC 2015 armv7l GNU/Linux
molloyd@beaglebone:~$ cd /etc/network
molloyd@beaglebone:/etc/network$ sudo nano interfaces

Why are Operators Used in Quantum Mechanics?
This post can be found here: http://physics.stackexchange.com/questions/77275/why-do-we-use-operators-in-quantum-mechanics
Q:
In classical mechanics, physical quantities, such as, e.g. the coordinates of position, velocity, momentum, energy, etc, are real numbers, but in quantum mechanics they become operators. Why is this so?

That Time Faith and I Went Skydiving
Faith and I went skydiving back in 2015 before we got married. We had a blast, though when we landed Faith’s instructor said it was the scariest jump of his life. Unbeknownst to us the drogue chute that is used to reduce the terminal velocity when tandem jumping became wrapped around the instructor’s neck briefly. He managed to get it off, but he said it could have ended very badly. You can see this happen at the 50 second mark in the video. Apparently drogue chutes are used when tandem jumping because two people strapped together fall a lot faster than does a single person. This excessive speed could make deploying the main chute more dangerous. Getting tangled up in them isn’t unheard of as you can see in this video of a woman who was injured when the drogue chute wrapped around her ankle and couldn’t be removed by the instructor: https://www.youtube.com/watch?v=1Ksk2Y9BlUg.
We had a great time though, and wouldn’t have even known about this near miss unless he had mentioned it to us.
Mt. Washington Winter Hike
I went on a winter hike on Mt. Washington on Friday, January 11, 2019 with my three brother in laws: Michael, Jesse, and David. Jesse had attempted to climb the 6,288 foot peak with his wife two years prior, and he came up with the idea of us all going back for another attempt. We had been planning this hike for several months, and spent a lot of time amassing the gear we would need. The rest of us didn’t really know what to expect as we had no experience with winter mountaineering.

I only use the PASM (PRU assembler) for programming the PRUs on the BBB. I’ve had some issues with the TI C compiler.
The best reference for the PRUs can be found in the GitHub reposotory here: https://github.com/beagleboard/am335x_pru_package

To view the output of a device connected to UART4 on the BBB (I’ve got a 9600 baud GPS device sending data to P9.11) first set the RX pin to the correct pin mode. I running Debian on the BBB by the way.
