A couple of lessons today bringing together all that we’ve learned so far in Module 2. I followed the first lesson through the full 30-minutes like a walkthrough. I always feel that typing (or writing in the traditional sense) what you’re going through helps it stay in the mind for […]

Following on from this morning’s lesson, Lesson 12 of CodeWithChris‘s Module 2 put the JSON techniques into practice. Data has to come from somewhere and, whether that’s from a database or a flat file, it’s still just data. JSON ensures that the data is available/presented in a common standard format. […]
I’m continually finding it amazing that much of that which I’ve taught myself over the years actually has a common method in use as a standard part of coding. The code that I concocted myself for my PHP scripts that handled data from MySQL/Maria pretty much utilised the flexibility of […]

Today’s lesson, lesson 8 from module 2, builds on yesterday’s insight into MVVM. The challenge requires bringing several things together that we’ve learned up until now. It’s only when you face a challenge like this that you realise how little has actually “sunk in” to the ol’ brain box. But […]

So, over the last several days, we’ve been learning many things that have a familiar feel to them. Struct, for instance, reminds me an awful lot of Class from my PHP OOP. Today we learned that we also use Class, which is very similar to Struct, only you can do […]
