Hi @bre, just wanted to let you know about my startup's seed investment campaign. It'd be really helpful if you can help, or just spread the word, thanks!
I'm excited to share that after almost two years of hard work at miiCare, we are opening up to public investment for as little as £10! Please spread the word! Make sure you can invest in UK businesses, and let's finally take care of our struggling elderly lnkd.in/e-wY9_K

My first attempt at space photography, the view of our Milky Way galaxy over Palo Alto! Spent last night with the @Stanford Astronomy Association in Monte Bello. More to come! 10 second exposure at f/3.5 18mm ISO 2000

Thought it was pretty spooky when my RPi was mysteriously pinned at 100% usage on the desktop, turns out it was just a German crypto currency SSH brute force hack. Kinda sudo rm-ed the Halloween fun. Oh well. Happy almost halloween

Can anyone recommend an easy way to program an Arduino BLE master to connect to a peripheral? Modules or libraries would be appreciated
