Fix Wordpress URL Migration Issues

Wordpress is fantastic, except when it isn’t. There are a few scenarios in Wordpress where you would want to migrate from an existing URL (e.g. your localhost, http://domainname.com, or https//abc.com) to a new URL (e.g. https://domainname.com). You can end up with a confusing setup and a broken site if you don’t go by the book! The easiest way to take precautions for a successful migration is to read a 100 line manual, or may lie in finding a “good plugin” that can migrate the site for you. ...

Web Development - The Problem of Plenty

Web developers today are a spoiled lot. I consider myself as an absolute beginner in the web development world, but I am truly amazed at the things I can do today with free / minimal cost infrastructure. The system automates everything except me - I am that stupid man in the middle. Despite stupidity, I can and want to build truly great stuff for my human brothers and sisters (and then some for the animals in you, for Alexa, Cortana, the robots and so forth). ...

Semicolon is Safer

Javascript has and always have people who fight about anything and everything. I am always on the one side or the other, trying to raise the pitch whenever I can. After all, what is life if there is no stupidity? We should get annoyed, irritated, angered and humiliated at every instance possible. But, this topic is different. This topic is about using a semicolon in Javascript. And, there is only one way shown by God or your belief system. ...

Platforms for Creating Courses

“Be a teacher to become a better student”, said none. But it is true to a large extent. It certainly helps the guru, if not the student :) While I have created a few short courses in my lifetime, there was nothing substantial. I had been trying to investigate available options for an immediate requirement and my deep PhD level research is outlined below. Trends of the Day Structure your courses - students today are exposed to some really good platforms (Udemy, FreeCodeCamp, Datacamp, Coursera, Salesforce Trailhead etc.) ...

Collaboration Tools for Developers

There are two primary things of interest from a communication perspective - One to one/many collaboration with team One to many collaboration with the world The tools outlined here are great from both perspectives, but choose your poison carefully. 1. Team I am sure you have a bunch of tools from your organization - but let’s be honest. Most of the “org approved” tools are redundant by the time they get approved by the security team. ...

Copy/paste Datatable Issues in Hugo

It is interesting how the minor things eat away a lot of your time. Especially if you happen to be like me, one of the greater idiots on a planet full of idiots. One of the days, I had to create website really fast to demonstrate to a potential customer. I abandoned my dear old friend Jekyll since - well, I had to create something in Hugo. There was a requirement to show a data list (phone numbers and some related information) on one of the pages. ...

3 Great Programs to Access your Databases

I worked with Oracle DB for a long time. Later I switched to MySQL, MariaDB, and a tiny bit of MongoDB. All the SQL databases I worked did not quite boast about exciting developer experiences. Oracle had SQLPlus, which was foresaken by everyone but a few diehards. Fortunately, we also had SQLDeveloper or Toad (to those who could afford that). Unfortunately, Oracle was actively used at my work place. MySQL and friends were not. ...

Backup - Your Life Depends on It

Backing up has been historically a pain. Most of the times I lacked the resources - either I don’t have the hardware or could not quite setup everything seamlessly. Previous Setup Create Synchronicity Light-weight, backup and synchronise. I include any folder that needs to be backed up to CS. Schedule the program to run every fortnight or so. The files are backed up an attached hard-drive, some folders go to OneDrive, Dropbox, Box, or Google Drive folders. ...

Create Beautiful, Performant Sites [Free eBook]

I had been exploring Jekyll for quite sometime. I simply followed the below traditional, developer like approach - download Ruby download Jekyll play around with platform capabilities - focus on Liquid see how themes are created However, I realised mid-way that select themes offer a good way for anyone to get started. Just copy themes to your own repository Edit content Go-live on github.io This information is available to anyone who is remotely interested, but the conversation on such sites were not as prevalent as they should be. ...
