paragraph 2

This text is supposed to explain how to get to the graphic user interface from Linux start-up in command line mode --

" ...you'll get the command line when you boot up, and you'll have to log in and start the graphical interface manually like this:"

BUT then the following 2 paragraphs explain just the opposite procedure -- how to get from the GUI to the terminal !

Table 2-1

Description of what "/" signifies (root) is blank -- this should be explained in a book for beginners.

3rd paragraph in "Hello, Python" section

This paragraph suggests there might be a syntax error using "print()" with earlier versions of Python. It is true that this is a syntax error with older versions of Python, but it is not in recent versions of Python 2.7.x, which is the older version which comes with Raspian.

Note, bottom of page

Note errs in describing action of Serial.write() Arduino command when sending a single byte argument. It sends that byte (as binary) to the serial port; then whatever is receiving the serial output -- the Arduino IDE's serial monitor, terminal program on a PC, a Python program (or some other program) -- has to process that binary according to its own purpose. The serial monitor (like any standard terminal) will display the byte as the ascii character corresponding to the byte's value. Example: Serial.write(123) will print a L curly brace ({) on the serial monitor.

The last sentence of the Note (left incomplete) should be completed to say: "Use the Serial.print() command to send the (byte) number to the Python program (or the serial monitor/terminal, for that matter), as a character string corresponding to the byte value. Example: Serial.print(123) will print 123 in the serial monitor, or send the string "123" to the Python program."

Figure 8-4

Figure 8-4 and the accompanying text describe how to connect an LED to Pi. Many other sites use this example as a first project for us beginners. However all the other sites insist a resistor is required to prevent Pi from burning out the LED.
e.gg.http://www.thirdeyevis.com/pi-page-2.php

I think the resistor is necessary, too. Am I wrong, or is there an omission in this otherwise ne book?

You still need to be executing theses commands as root.

Theses should be these.

In the "Capturing Video" section

The text should probably mention that omxplayer doesn't work with a headless setup.

3rd code block in "Capture a Video"

The code example has the following code:

$ raspivid 2>&1 less

But I believe there should be a pipe character before the "less", as in:

$ raspivid 2>&1 | less
