Figure 1-30

In figure 1-30, the menu that is displayed is the Bluetooth menu (It's the correct menu) but the highlight circle is on the wrong icon to get to that menu. The circle is on the network (WiFi in this case) icon. It needs to be moved over one icon to the left. Nothing major, just a slight correction.

Note from the Author or Editor:
In figure 1-30, please put high contrast circle around the Bluetooth icon (top center)

middle section

It looks like www.apixu.com has changed to www.api.weaterstack.com in Oct 2019. The url elements and also the JSON returned elements are now different and so this section will need changed in order to work. :)

Note from the Author or Editor:
I've now fixed this on Atlas.

Hello.
Great book. I have a clarification question for you.

On page 223, Computer Vision, the book talks about OpenCV... then the Problem statement has OpenCV 3..then the pip install has 4.1.0.25...then on page 224 we do a cv2.__version__.

That all said, I'm relatively new to Python and when I went to Amazon to see if there was a book on Computer Vision... there was CV2 3 and 4. My take on the first paragraph is that we've installed 4.1.0.25...and the OpenCV 3 is a typo...and the cv2.__version__ is to keep the Python package the same for legacy purposes.

Please advise.

Thanks,
Darren

Note from the Author or Editor:
Recipe 8.1: in Problem statement, change 'OpenCV 3' to 'OpenCV 4'

The bottom led of the LED is one row too high.

Note from the Author or Editor:
That's correct - please contact me for a replacement figure. I have one that I made for the Japanese edition.
