Low Level Debugging

Here's a small tip which I found extremely useful when I came across this type of (loosely) documented crash.  The problem is, it is extremely difficult to know at what point it crashed as there is no stack trace as part of it.  Likely as well (as in my case), it was in a vendor component (composer, etc.) which was designed for a different version of PHP.

Well, here's the answer.  This guide shows how to create a simple script to include in to your program, which will echo out a filename and line for each "tick" that PHP is processing.  The last one it gets to before it crashes -- bingo, you know what's causing the problem!

Hope this helps!

Running NodeJS Serverless Locally

 So it's been a long time, but I thought this was a neat little trick so I thought I'd share it with the world - as little followers as I have.  In my spare time I've been writing up a new hobby project in Serverless , and while I do maintain a staging and production environment in AWS, it means I need to do a deployment every time I want to test all of the API's I've drafted for it. Not wanting to disturb the yaml configuration for running it locally, I've come up with a simple outline of a server which continues to use the same configuration.  Take the express driven server I first define here: And then put a index.js  in your routes folder to contain this code: Voila! This will take the request from your localhost and interpret the path against your serverless.yml and run the configured function.  Hope this helps someone!

question2answer Wordpress Integration

 Today I want to journal my implementation of a WordPress site with the package of "question2answer".  It comes as self-promoted as being able to integrate with WordPress "out of the box".  I'm going to vent a small amount of frustration here, because the only integration going on is the simplicity of configuration with using the same database, along with the user authentication of WordPress.  Otherwise they run as two separate sites/themes. This will not do. So let's get to some context.  I have a new hobby project in mind which requires a open source stack-overflow clone.  Enter question2answer .  Now I don't want to come across as completely ungrateful, this package - while old, ticks all the boxes and looks like it was well maintained, but I need every  page to look the same to have a seamless integration.  So, let's go through this step by step. Forum Index Update This step probably  doesn't need to be done, but I just wanted to mak...

Auth0 - Removing Social Accounts

Greetings!  Long time it has been.  Today's post comes from a project I was handed to convert the tens of thousands of users through our website that are using social accounts into email/password logins.  It has served us well over the years, but with the on-going scrutiny from the changes at Facebook, and the integration we need to do with our online shop which does not have social authentication - makes sense it is time to remove. But what is the cleanest way? We want to make this as seamless and easy as possible for our customers and with one EDM delivery.  I have come up with the following procedure: The comments should make it fairly self-explanatory.  What you may find interesting is that we are deleting the corresponding user from Wordpress .  This will get re-created after they sign in with the new user ID.  If you are curious on the SQL that can be used to look up and delete the user by the Auth0 user_id, you can use this query: From there you...
