How to get Jetpack to resync your self-hosted WordPress contents with WordPress.com

For some reason, the content on my self-hosted WordPress website did not tally with the site stats on WordPress.com. The number of drafts and published posts were wrong and the insights page does not reflect my published posts for the past two months.

Tinkering with the WordPress.com interface, I was able to find a way to get Jetpack to resync my self-hosted WordPress contents with WordPress.com. This post documents how I managed to do so.

MT5003 Creativity Portfolio

Part of my grades for MT5003 Creativity and Innovation consists of a "Creativity Portfolio" that tells something about myself in a creative and innovative way.

After the completion of my "Creativity Portfolio", I document my thoughts in this blog post.

Setting up WordPress on Raspberry Pi 3 with Raspbian Stretch Lite, nginx, MariaDB and PHP 7 as the LEMP stack

Raspbian Stretch was released on 17th August 2017 and this will mean that we will be able to get a variant of Debian 9 on our Raspberry Pi. With Raspbian Stretch, we will be able to run WordPress or any PHP framework with PHP 7.0 which Zend had indicated a performance boost of up to two folds as compared to PHP 5.6.

Before porting my blog over to PHP 7, it will make sense for me to perform a little proof of concept on my Raspberry Pi 3 first. With Raspbian Stretch Lite, I can see for myself that my blog runs well with PHP 7.0 before spawning a new Digital Ocean instance for Techcoil.

This post documents how I setup an instance of WordPress on Raspberry Pi 3 with Raspbian Stretch Lite, nginx, MariaDB and PHP 7 as the LEMP stack.

Proving that we can use jQuery to push a dynamically generated file to the web browser based on the user's input

In order to demonstrate the possibility of using JavaScript/jQuery to push a dynamically generated file from the server backend to the browser, a sample scenario was created.

There is a number dial that changes rapidly and a text field for the user to enter his name. When the user clicks on the "get lucky number" button, jQuery is used to send the lucky number on the number dial and the user name to the server.

The server generates a text file based on the input from the user and sends the file back to the browser. The browser will then show a download dialog box for the user to decide whether to save a copy of the file or view the file using one of the native applications found in his/her computer.

Using jQuery to access the DOM structure of parent HTML webpage from within the child HTML window

This is a demonstration of how a child web page can access the DOM structure of its parent web page using jQuery and JavaScript.

It shows a button on the parent web page to spawn the child web page in a separate browser window.

The child web page provides a text field and a submit button to write user's input to the parent web page.
