Radical Suggestion: Use Completely JSON in webpages/browsers. better than HTML

We are using Json in many "data presentation" tasks. Why would it not be the case for creating/displaying webpages ?
I make a Radical Suggestion: Use Completely JSON in webpages/browsers.
That is, a website should be presented in JSON (like named array), browser (including engines, renderers) should interpret and show pages from these json data. This would speed up many development and parsing needs.. Many computer/processing/energy power may be saved worldwide.

Installing Ehcp in a virtualmachine on Ubuntu 19.04

Installing Ehcp in a virtualmachine in your destop (or even server), on Ubuntu version 19.04:

sudo apt install vagrant
mkdir ~/ehcp_vagrant
cd ~/ehcp_vagrant

vagrant ssh
wget ehcp.net/ehcp_1804.tgz

Ehcp Version 18.04 first preview available...

We have prepared first preview version of Ehcp 18.04, which is for Ubuntu 18.04.
You can download and try/test it from http://ehcp.net/ehcp_1804.tgz

We have tested only basic functionality. Ehcp installs directly, ehcp login works, domain/ftp add works.
We did not test every detailed feature, please test yourself and share your test results with us via info@ehcp.net.

A fix for Ubuntu 16.04

With Ehcp 0.38.5 and later (on Ubuntu 16.04), init scripts in /etc/init.d may cause some apt update commands to fail. So, please move ehcp and ehcp_daemon.py that is in /etc/init.d to some other location, until this is fixed.
After this move, apt -f install command would fix the apt system.
