Some quick definitions with links – because I’m consistently having to explain this to people. (And next time I can just copy-and-paste.)
The Ionic Framework is a powerful development framework which brings together HTML5, AngularJS and Cordova. See http://ionicframework.com

jQuery formBuilder is a lovely stylish formbuilding tool, with all the front-end features a developer could desire. But the documentation is a little short of examples for integration with a backend system + database, and the gitter chat is completely full of people struggling with the basics.
I’m writing down some integration notes to keep it clear for myself in my head.
I’ve tried to keep this code as simple and as framework agnostic as I can.
Example code = dirty code. Do not use in real-life.

I love this story. It’s from the early days of the interwebs, mid 1990s.
Many stories from the world of IT support will leave you feeling that “everyone who asks for help is a fool”. It’s a world where the Bastard Operator from Hell is still seen a positive role-model, and any assistance often comes with a hefty side-helping of contempt.
This one starts with the classic:
“We can’t send email more than 500 miles,” the chairman explained.
I’m reading this, and I’m braced for the traditional “Ha! Ha! These lesser mortals are such fools!”
But it goes on, and there is some investigation, and test emails are sent, and the user is entirely right. They can’t send email more than 500 miles.
It’s complicated; there are sendmail configuration files, and the speed of signals in a fiber backbone is relevant (this story has a FAQ page) but my main take-away is that.. wait for it…
THE USER WAS RIGHT

What is a finite state machine?
A finite-state machine (FSM) is a mathematical model of computation. It can change from one state to another in response to some inputs; the change from one state to another is called a transition. An FSM is defined by a list of its states, its initial state, and the inputs that trigger each transition.
Thank-you Wikipedia. That’s helpful.

Heredoc is a useful tool for larger strings, though they have an indentation quirk which always put me off.
To quote from the PHP Requests-for-Comments:
The heredoc and nowdoc syntaxes have very rigid requirements. This has caused them to be, in-part, eschewed by developers because their usage in code can look ugly and harm readability.
PHP 7.3 introduces two changes to the syntax for heredoc and nowdoc syntaxes:

Over the years, I’ve built a whole library of helper functions for working with dates in php, but I think they’re all a thing of the past now. Because I’ve been playing with Carbon Date library by Brian Nesbitt. It’s best described as Php’s
DateTime for humans.
Here follows a quick summary, but I’m just looking at the very tip of the iceberg. Lots more!

I use modal popups all over the place in my web applications. The most frequent use is to make the user confirm deletion, either by typing DELETE into a form or by giving a reason for deleting the item in question. And I want to make this work in Laravel.
Note: this is klunky. I’ve been playing with Laravel for a few weeks and if I end up using it as an ongoing development platform, then yes, things will be rewritten.

Familiar with password forms like this?
Restrictive password rules are not just frustating and unhelpful for people trying to manage logins for a multitude of sites; they (officially) do not do much for security on your website.

Every time I take my hands off the keyboard and reach for the mouse, and drag the mouse across the desk, I’m losing time. I’m going slower and moving out of flow. It’s especially true when I’m working with a large monitor, or dual-monitors, and I have to moooove the mouse all the way to where it needs to me. Or the mouse cursor has disappeared on me, and I have to frantically slide the mouse until the movement traps my eyes and I can see where it is on the screen.
We all know the basics are Cmd+C for Copy, Cmd+X for Cut, and Cmd+V for Paste.

These are my reading notes & a quick summary. If we’re aiming for big things, it’s easier to succeed if we get the small details right.
