Selenium Webdriver 2 fussing about Firefox version

Starting from version 3, Selenium is using Marionette - the new Firefox driver.

This note is about version 2.

Selenium has its own support pattern: http://www.seleniumhq.org/about/platforms.jsp

Firefox

Support for Firefox is the latest release, the previous release, the latest ESR release and the previous ESR release.

For example Selenium 2.40.0 (released on Feb 19, 2014) supports Firefox 27, 26, 24, 17

Selenium with Firefox can be run on any platform that Firefox supports for those versions, that also allow users to install a custom Firefox extension.

gem:
cucumber (2.3.2)

playing music on hold when launching a bash command

 This works using MacOS afplay

!/bin/bash

moh_file=~/Downloads/moh.mp3

afplay $moh_file &

pid=$!

trap "kill $pid" 2

while read line; do echo -e $line; done

kill $pid

Usage:
$ long-running-command [args] | moh_player

If you want to retain colours, run it through script:
$ script -q /dev/null long-running-command [args] | moh_player

Custom Error in NodeJS v7

Had a lot of trouble with it but finally found this solution on Node v7.10.0 :

Maps of London with zones, tube, santander bikes, universities, Aldi, Sainsbury, Poundland, Home Bargain, Coop

Are you moving into London?

Do you want to know what's up in your neighbourhood?

I am having this problem nowadays, that's why I created a Google My Map with these layers:

• TFL zones
• Underground lines
• Santander bikes (might be disactivated)
• Universities
• Stores location: Aldi, Sainsbury, Poundland, Home Bargain, Coop

Here is the link to the map: https://drive.google.com/open?id=1PVkweUYubQeimWL-Mqq5GTs_NKE&usp=sharing

Android tablet as second monitor on Ubuntu 16.04

Do you want to connect your tablet or mobile phone to your Linux desktop as a second monitor?

Apparently, nobody took this seriously.

So I decided to create a script that configures your X11 server and creates a VNC server automatically.

Yes, is working!

I am using Ubuntu 16.04 and an Android tablet.

It should work for both iOS and Android or any other device capable of running a VNC client.

It can do both landscape and portrait mode.

For androidians, it can also connect to your device through USB!

Here is the link:  https://github.com/mrenrich84/vnc_virtual_display_linker/blob/master/README.md

Let me know how it goes...
