Category: Programming Fundamentals

I decided to take a break from my usual programming and wandered the internet, I tried breaking away from any programming related videos. I was looking for something light, I don’t know maybe a web dev conference.

This post is based off a youtube video I stumbled on, it’s entitled “The Early Days of Id Software – John Romero @ WeAreDevelopers Conference 2017“. You know, I didn’t know who John Romero was and I played both DOOM and QUAKE back in the early 90s. John was rockin’ the long hair, it was super long, looked super cool though. I wish they would invite more people like John over to Web Dev Conferences.

If you’ve been programming for a while now, even if you consider yourself a novice, you’ve probably run into the SSH (Secure Shell) protocol. Now, don’t get intimidated by this technical term, this is just another protocol like FTP (File Transfer Protocol) or HTTP (Hypertext Transfer Protocol). So look, you’ve already engaged with a protocol at one point in your dev career. In simple terms, protocol’s are just a set of instructions to complete a given task.

Greetings fellow developers, I hope you’ve continued to immerse yourself in something interesting whether it’s programming, physics, math – or whatever. The point is – just keep pushing forward and don’t be afraid to fail. Seriously though, enjoy the journey of making mistakes.

This post is about two functions – PHP’s substr() and preg_match() functions.

Alright, this is a continuation of System Architecture, a super broad subject I’ve been recently immersing myself in. I must admit, my last post was a bit poor in quality – I even left things hanging in the end. So I felt compelled to dive in deeper into an architecture known as “Distributed Systems”, yes in one lesson by Tim Berglund.. As the name of this blog post suggests, this is based off a youtube video I found – Distributed Systems in One Lesson.

I’ve decided to take a break from some lower level stuff – server side languages, scripts and front end stuff. As in “break” – I meant in my blog posts. My thirst for more Javascript and PHP is unending so that is still quite active.

I’ve developed a sudden interest in system architecture – I think this was ignited off a job requirement I’ve recently run across. Almost everything listed as a requirement I had covered and even the ones I wasn’t quite savvy with I knew I could pick up pretty fast – ie frameworks and libraries. When I look at job requirements, I look at the underlying fundamentals or lack thereof with regards to my toolbelt.

This is my very first post on anything interview related. I figure it would be helpful to cover common Javascript questions during an interview. As mentioned in a previous posts, Javascript is totally different beast. From my experience, my interviews have been pretty tame. They were mainly OOP related questions but this was before ES6, before Javascript classes and constructors were introduced. I remember having to write literal objects on a white board and explaining this object’s properties and methods.

I haven’t had to use the Promise function constructor much, I think maybe I’ve used it a handful of times. I don’t know if this is a bad thing. To be honest, the concept of promises is still a bit fuzzy to me. I’d like to build more applications utilizing this construct but I haven’t had to write any programs that run too many asynchronous operations. Or, the need for it wasn’t necessary and I got away with writing a bunch of function callbacks. But that’s what Promises were made for – to eliminate what developers describe as “callback hell” – basically what you get is a chain of nested callbacks which makes for “unnecessary inefficient bloat”. Yeah that’s exactly what I called it.

So a little bit of history 101 when it comes to the ‘var’ keyword in Javascript. Back when Javascript was super weird, I mean Javascript is still weird don’t get me wrong. For this reason I started liking Javascript – I used to think it was just to messy of a language to write in. I had some major trust issues with it, my relationship with PHP was far better. Alright enough with relationships, let’s dive right in.

Yeah. Closures. I know I’m kind of late in getting to this. Closures have been widely discussed subject among developers and I feel like I should get a good handle on it myself. First things first though, it’s important to understand that closures in javascript are a feature not a built in construct. If you’ve been writing in Javascript you’ve already encountered closures you just weren’t aware of it. I think the concept of closures tends to intimidate or confuse a lot of beginners and even self proclaimed experts in javascript.
