python 3.7 install¶

sudo apt-get update -y
sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev -y


wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tar.xz

tar xf Python-3.7.0.tar.xz

cd Python-3.7.0
./configure
make -j 4
sudo make altinstall

 sudo ln -sf /usr/local/bin/python3.7 /usr/bin/python

/usr/local/lib/python3.5/dist-packages/mcpi/minecraft.py

/home/pi/Desktop/mcpi-scratch-server.desktop

Exec=lxterminal --command="/bin/bash -c 'python2 -i /home/pi/Documents/MCPiScratch/mcpi-scratch/mcpi-scratch-server.py'"

python pip install¶

sudo apt-get install python3-pip

To get the Python 2 version:

sudo apt-get install python-pip

For example, the following command installs the Unicorn HAT library for Python 3:

pip3 install unicornhat The following command installs the Unicorn HAT library for Python 2:

pip install unicornhat

1.3 Scratch 3.0¶

github¶

electron¶

npm install -g asar

asar pack app app.asar

asar extract app.asar destfolder

scratch extension¶

https://scratch.mit.edu/discuss/topic/289503/

node_modulesscratch-blocks

npm install

npm link

You can also use the command python build.py to build scratch blocks, but from my experience, changes aren’t reflected in the GUI unless you run npm link.

On my client PC I’m running Windows 10 and I have installed XMing and Xming Fonts.

I am running Putty and I have configured it to enable X11 Forwarding. I have tried leaving the X display location blank (as default) and also with the value :0.0.

On my server I’m running Ubuntu on AWS. I edited the /etc/ssh/ssh_config file to include the following two lines:

ForwardX11 yes ForwardX11Trusted yes

I also installed xauth using sudo apt-get install xauth

Whenever I try to run an application, like xterm & or xclock I get the same error:

PuTTY X11 proxy: Unsupported authorisation protocol Error: Can’t open display: localhost:10.0

Hit enter and select default options for any configuration popups, leaving mysql passwords blank

Install Node and Nodejs

Type curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash - And then sudo apt-get install -y nodejs

Install Ruby 2.2.3 with rbenv

rbenv install 2.2.3 rbenv global 2.2.3 rbenv rehash

Install yarn

First, type curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add - Then echo “deb https://dl.yarnpkg.com/debian/ stable main” | sudo tee /etc/apt/sources.list.d/yarn.list And lastly, sudo apt-get update && sudo apt-get install yarn=0.23.2-1

Finally, configure your mysql to allow for a proper installation. You may run into errors if you did not leave mysql passwords blank

Type echo “ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘’;” | sudo mysql

echo “ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘king0733’;” | sudo mysql >mysql -uroot -p

>ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘’; >FLUSH PRIVILEGES;

Read the following notes, then go back up to the overview and run the commands there.

If, for any reason, you are forced to interrupt the rake install command before it completes, cd into dashboard and run bundle exec rake db:drop before trying rake install again rake install must always be called from the local project’s root directory, or it won’t work. Finally, don’t worry if your versions don’t match the versions in the overview if you’re following this method; the installation should still work properly regardless

GRANT ALL PRIVILEGES ON . TO ‘root’@’%’ IDENTIFIED BY ‘king0733’ WITH GRANT OPTION;

X displays are protected by a “key” which you need to give in order to be able to connect. That key will generally be stored in the user’s ~/.Xauthority file.

To allow someone else’s application (like x11vnc) to connect to his DISPLAY, a user has to give him that key or grant him access to his ~/.Xauthority file. You can retrive the key of your display by doing.

xauth list “$DISPLAY”

You can grant access to your ~/.Xauthority by changing its permissions (group ownership or ACLs).

The other user can specify which authority file to use via the XAUTHORITY environment variable, or add a key to a specific display to his own ~/.Xauthority using xauth add.

chapter 19: WAVGAT Uno¶

https://forum.arduino.cc/index.php?topic=540421.0

I also had the same issue at first but I have found the solution…

Step 1

Download the following RAR file from the link below; https://drive.google.com/open?id=10gwrG9uTDwaEO-7EudsmBkfgdcyrcABI

Step 2

Once downloaded, extract these and copy the content within the “update” folder (not the “update” folder itself just the content inside it)

Step 3

Paste content to the following path on your computer… C:UsersAdministratorDocumentsArduino

Step 4

Restart Arduino IDE Software

Open Arduino IDE, select your COM port if required and Select your WAVGAT board type (WAVGAT boards are at the very bottom of the board list)
