Great introduction to LoRaWAN by Andreas Spiess: LoRaWAN De-Mystified

LoRa is a Low Power Wide Area Network (LPWAN).

• Network - Multiple devices communicating between each other
• Wide Area - Longer range than WiFi (and less power) and much longer range than Bluetooth
• Low Power - Comes at cost of bandwidth

Not a replacement for wifi. Great for low bandwidth sensor networks.

I try to avoid using the GUI to configure/run barrier so I created a simple bash script barrier-client.sh to launch my barrier client. It reads from a .config/barrier.cfg file I created to determine the client name and server to connect to.

cat ~/.config/barrier.cfg

BARRIER_CLIENT_NAME=${HOSTNAME}
BARRIER_SERVER=gilbert.lan:24800

This expects the client to already be configured to trust the server. That trust is managed by the ~/.local/share/barrier/SSL/Fingerprints/TrustedServers.txt which should have the fingerprint of the server.

rhash checker in python

rhash is a great utiltiy for computing hash sums. Even across full directory structures. Handy for creating checksum file manifests to verify complete transfer of files to another location.

Finds any *.sha256 files and assumes they are a checksum manifest for the directory of the same name. Runs a validation of each manifest found and reports if the file doesn't exist or if the checksum does not match.

The point of this is to use the rhash-check.py in Jupyter notebook environments where you can't use rhash directly. If you have rhash has built into it a better alternative to the rhash-check.py script:

rhash -cr --crc-accept=sha256 directory/

chef omnibus build script https://git.io/fpiRe

Chef omnibus build script to automate a build of chef for ARM. Primary goal to support rasbian_bootstrap.

curl -L https://git.io/fpiRv | sudo bash

The core details derived from Mattray's Chef14 ARM on the Beaglebone Black post.

This is a fully scripted build and install of chef for Raspbian (or any other deb).

• installs build deps

The Windows Linux Subsystem (WSL) comes with /win/c mounted world read-write and is setup for compatibility between windows and linux by putting all your windows paths into your linux system path. This is great for some usecases. Some tools get grumpy having these world writable directories a users path. While this doesn't break them but it can cause annoying warning messages.

On the other hand, when you don't care about the windows tools being in your path, it might make you more sane not to see those error messages, and also to limit the number of places tools look for supporting binaries not-relevant to themselves.

: warning: Insecure world writable dir /mnt/c in PATH, mode 040777

• Microsoft/WSL #1426 - warning insecure world writable directory

You can remove all those /mnt/c paths from your $PATH with the following line:
