Pragmatic Lessons of Rails & Ruby in the Enterprise by Nathan Beyer

Adopting Rails and Ruby for use within a large development organization was and continues to be an adventure. Rails and Ruby have been in use at Cerner for 7 years and over that time, their use has gone from niche technology used by a handful of people to a core platform used by hundreds. Along this adventure, we have learned many lessons and gained lots of experience. In this talk, we’ll share the interesting up and downs of this adventure in an effort to share our experiences and knowledge.

I had tried to make this work since I became a patient close to a year. I have to call over and over to get a new user name and register over and over again. After I do all that it works once and then it stop working the next time I try to get in....please help us...we are all patients and families with serious health issues and and have to deal with this problem.

Allison Chua

Cannot get in again!!!! My mother is a patient and I cannot see it when I try all the time.

Deborah Tozzi

I have set it up with a password but the next time I tried to go in, it would not let me in....just says call the office for information how to sign up. Very frustrating.

Kathy Barker

i have had nothing but trouble trying to see my chart.  Sometimes it works, and 50% it doesn't.  Must be improved.  Is this a cheap web site?

Log data with a DHT22 temp sensor & a Pi to Google Spreadsheet

1 984 views | 16 May. 2020


Hey there!

In this video I’ll connect a DHT 22 sensor to a Raspberry Pi. We’ll read the temperature & humidity out of it, write the data to a Google Spreadsheet and display it in a nice look line chart.


All you need is a Raspberry Pi and the DHT 22 sensor I used in the video. You’ll find for around 5 Euro/Dollar at your favorite dealer. With these little preassembled sensor boards you are ready to go. If you only buy the sensor it self you may need some resistor to get it working.


We’re using the Adafruit DHT lib. In the meantime it’s declared deprecated. This means the vendor doesn’t actively support it. I created an unmodified fork of it so that you can still use it in the future like in this video.

AdafruitDHT lib: https://github.com/datort/Adafruit_Python_DHT

Temperature Chart lib: https://github.com/datort/raspi-temperature-chart

Google Developer Console: https://console.developers.google.com/project

Google Docs: https://docs.google.com

Feel free to comment if you have any questions or suggestions.

Thanks for watching!

Sir can you help me how to configure moisture sensor to raspberry Pi

William Burlingame

When I ran "sudo pip install gspread oauth2client", I got the error message "google-auth 1.19.2 has requirement rsa<4.1; python_version < "3", but you'll have rsa 4.5 which is incompatible." Now what should I do to recover?


whats the exact model of the DHT22 sensor that you used?

Svavar Jakobsson

Excellent tutorial, worked like a charm thank you!
Do you know how to edit the script so that I can take readings from 2 DHT22 sensors?

joan ser

Thank you for the video. I have a problem i cannot solve.
(this is my first codding with python so im a begginer).
When I lauch "./google_spreadsheet.py"
I have:
ImportError: No module named gspread.
I have tried to install Gspread, but it's apparently already installed.
As i understand, on my Pi, there is Python 2 and 3. On google i found that the problem could come from the version of Python where Gspread is installed.
i tried "pip install gspread"
"pip3 install gspread"
but it's apparently installed in both.
i would need some help.
