   No development methodology can eliminate the fact that building software is hard, and complex data systems quickly grow exponentially in complexity. Developing and maintaining a large project will be difficult, no matter your approach. Whic

   How is this not the same conclusion as other studies that find that index funds out perform others?

   Any chance some of this is related to patent avoidance?

   At this point I’d be thrilled for any movement of policy in this direction, no matter who’s behind it.

   I really hope this trend reverses soon.

   Good question. I'm really benchmarking the system against itself, year on year, by comparing the weather outside vs. performance (output temperature of the HVAC unit, average temperature inside the house). I'm not trying to find a

   Maybe there should be a help group for people like us?

   Absolutely overkill for most of these things, but I've been managing linux servers for 20 years now and find it really easy and fast to get a Pi up and running to do what I want. There's also some efficiencies from having everythi

   I have a Pi connected to a BME280 breakout board that I got from Adafruit ( https://www.adafruit.com/product/2652 ). It's also connected to a Dallas 18B20 temperature sensor. The sensors are outdoors in a small acti

    I just went to look at my crontab again. Some highlights (lowlights?): - Turning lights on/off around the house, because I found cron to be a more reliable scheduling agent that the one built-into my Wave software when I first set it u

    Just temperature monitoring, really. I have sensors measuring temperature right at HVAC input, output, attic temperature, as well as home interior temp and outside temp and humidity.

    I have used mostly light switches, dimmers, and a few isolated relays, plus home power monitoring. My experience is that it has all been rock solid. I’m using most GE branded in-wall light switches and they’ve been very reliable for me. Mis

    For temperature only I prefer the 18B20 sensor. They’re very easy to interface with and they can be at the end of very long wires. Adafruit has a bunch of sensors that work over the i2c bus; they’ve included python code for accessing the da

    I do this primarily because I'm a weather geek. I don't _need_ this at all. I do find it interesting to see the differences in temperature (and humidity, etc.) in the microclimate around my house compared to the city and greater m

    Are you running Windows on the Pi, or did you write your own software to interface with the sensor over USB?

    Started a consultancy, ran it for 5 years, closed it down. YMMV. My experience: Running a successful tech consultancy has nothing to do with actually building tech. The only thing that matters is sales. I'll say it again: the ONLY thin
