Predicting the Future (Tides)
The beach outside our Whidbey place is amazing. There’s about twenty yards of firm sand and rocks along the shore, then a broad, flat, soft expanse of sand/mud/clay for just under 100 yards, then maybe 30 yards of firm sandbars. Beyond the sandbars, the channel drops to a depth of about 500 feet or so…
Real-world IoT with LoRaWAN
Remote monitoring of a community water tank for under $500, that works kilometers away from wifi or cell service, incurs no monthly fees, and uses a battery that lasts up to ten years? The future is here! I’m super-impressed with LoRaWAN, The Things Network and my Milesight Sensor. Read on for all the nerdy goodness.…
Nerdsplaining: SMART Health Links
This is article three of a series of three. The first two are here and here. Last time here on the big show, we dug into SMART Health Cards — little bundles of health information that can be provably verified and easily shared using files or QR codes. SHCs are great technology and a building…
Bionic!
Last Tuesday I got up in the morning, showered and ate some breakfast, took the dog out, did the crossword, got a new pair of eyes, took a nap, watched the Mariners game and went to bed. In case you missed that, I got a new pair of eyes. OK, new lenses to be precise,…
The Most Important ChatGPT App Ever
I’ll grant that I have a relatively nerdy social circle — but it’s still sort of shocking just how many people I know are actually doing useful and interesting things with ChatGPT. Just a sampling: Just to iterate what I’ve said before, I believe this thing is really real, and it behooves everyone to spend…
Looking back at Azyxxi… er, Amalga.
Just a few months after the Great Gunshot Search incident of 2005, I found myself at Washington Hospital Center while Dr. Craig Feied showed us list after list on a huge (for the time) monitor. Real-time patient rosters for the ER and ICU, sure, but that was just the warmup. Rooms that needed cleaning. Patients…
Roku Channel SDK: Ferry Cameras!
Lara and I shuttle regularly between Bellevue and Whidbey Island in Washington, so the Mukilteo-Clinton ferry is a big part of our life. WA actually runs the largest ferry system in the USA, with 28 boats tooting around the Puget Sound area. Super fun day trips all over the place, and the ships are pretty…
Skynet or parlor trick? ChatGPT is both and neither and more.
If you haven’t played around with ChatGPT yet, you really should. It’s a pretty remarkable “conversational model” that interacts more or less like a real person. It has been trained on an enormous amount of factual data and understands not just informal speech (“Why are so many people bad at parking?”) but forms of literature…
TMI about Diverticulitis
Pretty unusual topic here — but it’s one that (a) has been taking up most of my brain the last few days, and (b) will hopefully be useful search fodder for others who find themselves in a similar way. I spent a lot of time trying to figure out what the various stages were “really”…
It’s Always a Normalization Problem
Heads up, this is another nerdy one! ShareToRoku is available on the Google Play store. All of the client and server code is up on my github under MIT license; I hope folks find it useful and/or interesting. Algorithms are the cool kids of software engineering. We spend whole semesters learning to sort and find…
