@bararchy I noticed you showed an interest in bluetooth. I actually prototyped both sides of a bluetooth embedded device with Crystal (Microchip firmware). As a C programmer Crystal is great for something like that since you have code transparency (you can see easily how you would implement in C ~ see all the way to the machine'ish) compared to Ruby for instance.
Wow! This is awesome
Yeha, I worked on getting a Bluetooth device for crystal
Great - I sorted out the unordered node problem by doing a dummy first run and making a mapping of where graphviz puts nodes, and using that mapping for subsequent runs
