        self.buf = bytearray()
        self.s = s

    def readline(self):

        if i >= 0:
            r = self.buf[:i+1]
            self.buf = self.buf[i+1:]

Flask apps are bound to port 5000 by default. To bind it to port 80, you would need to change the port as follows:

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=80, debug=True)

And to run it:

justinmklam

var FeedReader = {
 
    settings: {
        feedItemsCount: 10,
        url: 'http://someurl.com/news/feed/',
        feedListing: $('div#feedListing'),
        loadFeedButton: $('a.loadFeed')
    },
 
    init: function () {

Although sudo apt install nodejs works, it's not recommended because there will be permission issues when trying to install packages globally (ie. npm install -g sass).

A better way to install Node.js is to use Node Version Manager (nvm).

Installing with NVM

# Check the github page for the latest version

This seems to be a common problem on most MSI laptops, including my own GP62 6QF Leopard Pro. Supposedly, one way to fix it would be to update your BIOS, however, this didn't work for me.

I managed to fix this by adding this to /usr/share/X11/xorg.conf.d/10-quirks.conf:

Section "InputClass"
  Identifier "Spooky Ghosts"
  MatchProduct "Video Bus"
  Option "Ignore" "on"
EndSection
