STICKY: Errata

[sam nazarko]

The article on setting up a Pi Powered PVR with OSMC is great.

Just a heads up that we recommend sudo apt-get update && sudo apt-get dist-upgrade -y, sudo apt-get upgrade can cause problems (as new dependencies are not captured). You can also update via My OSMC > Updater.

I'll make sure that the firmware you reference in the article makes it in to a future version of OSMC

Also: OSMC itself is not quite based on Raspbian. The ARMv6l (Pi 1) version is, but the Pi 2 / Pi 3 versions are based on Jessie upstream. You could say that as OSMC is a Debian based operating system just like Raspbian, it has the full package repository.

In issue 53, page 23, the code block:

Code: Select all

10 % 2 == 0 # this is odd
11 % 2 == 1 # this is even

This should be:

Code: Select all

10 % 2 == 0 # this is even 
11 % 2 == 1 # this is odd

Issue 53 (the latest), on page 76 it shows a link (magpi.cc/1MYYTMo) to the ISO image for Pixel. When I follow that link it takes me to the RPi downloads page, with no options to download an ISO image for an Intel laptop. Can I get a corrected URL for the ISO image? Please.

[DougieLawson]

ISO download is here: http://downloads.raspberrypi.org/pixel_ ... jessie.iso

There's an error in part 8 of my Introduction to C series in the February 2017 issue. On the second page, the description of the strlen function should read "this tells you how many characters are in a string, excluding the terminating zero character." Apologies for any confusion caused.

[ddrouin]

There's an extraneous variable declared in the formatted output example on page 66:

int value;

Thanks for that - we'll remove it for the next version.

Page 28 Step 10 and Page 30 Step 3. The instructions for setting up the AIY Projects tell you to rename the Assistant API authentication file to client_secrets.json and the Cloud Speech authentication file to credentials.json.

The instructions on aiyprojects.withgoogle.com say to rename them assistant.json and cloud_speech.json. Google updated the file names for the authentication.
Both methods work, but we suggest going with with aiyprojects.withgoogle.com nomenclature as it is more recent.

There is a discussion elsewhere in these forums concerning the Dash buttons item in Issue #57.

Issue #58, page 42, "Getting started with GUIs"

At >STEP-01, text reads "Now open Python 3 (IDLE)"

But the IDLE IDE uses Python 2, and guizero requires Python3.

For clarity, maybe the text should say: "Now open Python 3 (IDLE3)"

[lucyhattersley]

It refers to the Menu Item which is listed as Programming > Python 3 (IDLE).

I like to refer to the precise menu item names so as not to confuse newcomers (who might look for Python 3 (IDLE3) in the menu but not find it and wonder if their installation is wrong).

[DougieLawson]

For clarity, maybe the text should say: "Now open Python 3 (IDLE3)"

Maybe it should use some joined up thinking and tell folks to try out the shiny new, better Python IDE "Thonny" that's documented on page 6 of the same edition?

IDLE is a pain, IDLE3 is three times the pain of IDLE.

I'm being nit-picky here, but I think there's a typo on page 26

It says 'Aint everything!'. I think it's supposed to be paint everything!

I've just added some Errata to AIY Voice Essentials:

• Page 38, Step 06: Only the red light on the Raspberry Pi will switch on at boot (not the LED inside the arcade button).

• Page 39, Troubleshooting Tips (item 2): Recent Voice Kits don't allow rotation of the lamp.

• Page 39, Troubleshooting Tips (item 2): Check that the wire colours are the same as the picture in Chapter 3, Step 21.

Sorry folks a few errors in my article, in Issue 65, Coding in C++

to install code::blocks use

sudo apt-get install codeblocks not as listed sudo apt-get codeblocks


on the paragraph headed Starting with C++, the file you need to create (the last reference is Game.h) should actually be SimpleObj.h

Issue 66 - Page 54 - Schematic Diagram on top left of page.

Schematic diagram shows a push button being connected to 5v and a GPIO pin. Switches should only ever be connected in this way to 3.3V.

[KanoMaster22]

A bit late but in issue 58 on page 69 the Voice Hat Hardware Extensions diagram says MOSI is GPIO 9 but I think it should be GPIO 10.

[robthez]

On page 50 of issue 67, we have an American writer doing a tutorial that uses a lamp powered by mains electricity.

We absolutely should have put a warning to be careful when messing with mains electricity. Please be careful!

Step-05 (Recording video), page 33 of the Official Raspberry Pi Beginner's Book.

For ten seconds, use raspivideo -t 10000 -o video.h264

The above command didn't record a video. So I googled and learned that the command should start not with raspivideo, but with raspivid.

Page 37 of The Official Raspberry Pi Beginner's Book. Following quote is from the explanation (found at the lower-left part of the page) on how the information of a file is displayed in the long listing mode.

>File size: The name of the file.

I think it has to be changed to 'The size of the file.'

Issue 68, p36-37 – The maker of the Pixel electromechanical display is Gavan Fantom, not Fortune. Apologies to Gavan for the mistake.

Page 12, "Compute Module Motherboard." The team at resin.io inform us that the pre-release versions of the Fin board was able to work with eMMC-populated modules. However the released board will NOT support eMMC-populated modules. It is intended for operation only with modules not already populated with eMMC (the CM3L today.).

Issue 69, page 38: For playing music using omxplayer it says to use the following:

Code: Select all

oxmplayer ~/Music/Anton_Rothschild_-_03_-_Its_Not_Vegas.mp

It should be omxplayer, not oxmplayer.

Had to look up external references to see what was going on.
Apparently its got to do with changing ownership using those octal
numbers. This is done by using chmod XXX filename where XXX refer
to the octal numbers spoken about in the article.
