Right now only version supported is for Ubuntu Linux Trusty (14.04). Zeal is available for previous version but are not supported officially.

Issues and Solutions

• I faced a minor issue after installing Zeal. I was not able to see main menu on top of it from where you can I found solution at zeal issues . I tried removing appmenu-qt5 package which worked from me. 

• Every time starting Zeal will show a popup that it's Hotkey is confliting with system's. So I changed it's default Hotkey from Alt + Space to Ctrl + Shift + Space (Synapse is already using Ctrl + Space)

Installing Synapse launcher in Ubuntu 14.04

I recently upgraded from Ubuntu 12.04 LTS to 14.04. I was quite used to of the Awesome Synapse launcher on Ubuntu 12.04. Just press Ctrl + Space and synapse is there to serve you.

Unfortunately Synapse is not directly available through Software Centre in 14.04. But you can install through testing PPA. just follow this steps

1. Open terminal and add the ppa and press Enter

sudo apt-add-repository ppa:synapse-core/testing

2. Now update the Software Repository and after that install synapse

sudo apt-get update
sudo apt-get install synapse 

That's it. Now enjoy the awesomeness of Synapse.

Accessing Guest (VirtualBox) Node.js Application from Windows/Ubuntu Host

If you are running a Node.js Application inside a Ubuntu VirtualBox machine and want to test the same application in any browser inside your Windows/Ubuntu Host OS, then follow this small tutorial. You can even test the application on any other device in same wifi or lan network as your Host/Guest Machine.
The main reasons I wanted this kind of hack is

• The Guest machine becomes slow and laggy if you start any browser in it to test your applications.
• Sometime you just want to use CLI 1.
• Test the Web Application in mobile or tablet device.

I am explaining here the steps to make it work.
