Last night I presented my talk on getting started with testing in Laravel at the Developer User Group in Cape Town. These are the slides for this talk.

Articles about the world of Freelance development and being self employed
This question, along with “How do I find clients/work?”, is probably the question I get asked the most from folks starting their freelance journey. And then when I tell them what I charge (or used to charge before I started working full-time at Castos), they respond with shock, as it’s usually triple what they were expecting. So this post is a short summary of links which explain my response to that question.
The definitive guide to calculating your billable rate.
Why I charge the rate that I do.

Additions and upgrades
It’s been just over two years since I moved into my current office space, and just over a year since I last wrote about it. As my two major hobbies outside of my work as a developer are jiu-jitsu (which not many folks can relate to), and computer hardware and peripheral upgrades (which most can at least understand) I thought it might be interesting to look back at what changes I’ve made in the tools I use every day, over the last year.
The Workstation
Last year I posted a review of how my workspace had changed over the 2 years since I left employment and become a freelance developer. It included this image of what my desk looks like, with a short run down of everything you see (and don’t see) in the picture.
Today, just over a year later, there have been some small but important changes.
So besides the less bright lighting (more on that later), the more keen of eye among you will have noticed some subtle differences.
Firstly, my peripheral monitors have changed. I was able to pick up a newer Samsung and Dell 24 inch monitor, so now all three screens are LED powered, and the two side monitors are more uniform. I’ve definitely noticed the difference in the visual quality improvement in making sure all three monitors are LED, I no longer feel like I’m having to adjust my eyes when I switch between the different screens.
The other major changes are in peripherals, I’ve replaced the Logitech headseat with a Sennheiser HD 280 Pro studio set, and replaced the short mic stand with a proper desk mounted arm. This allows me better use of my screens and keyboard when I’m in online meetings or recording podcasts (which I’ve not done as much as I’d like to in 2019)
I also treated myself to a Sparkfox Atlas Wireless Bluetooth Controller. This is a great little gaming controller, which I can use connected via a USB cable or via Bluetooth, works on both Windows and Ubuntu and has a very similar layout to an XBox controller.
Finally, as I noted earlier, I’ve switched from using the oppressing overhead florescent lights to a smaller lamp which sits behind the left screen. It gives off just enough light for me to see the things I need, without making my eyes water during the day.
The Laptop
While my workstation has only undergone a few external changes over the course of the last year, I eventually decided it was time for a new laptop this year.
I usually try and use a laptop for at least 4-5 years before replacing it. I’d been mostly happy with the performance of the Dell Inspiron gaming laptop I’d purchased at the end of 2017, but I ended up doing more conferences and therefore travel in 2019 than I had done previously, and two things became clear. First, the laptop and bulky, ungainly charger became heavy when carrying them around a lot, and second, the battery only held around a 4 hour charge.
I’ve always been partial to Dells, and the Dell XPS 15 seemed the logical choice. However, an online friend had recently purchased an Asus Zenbook, and was raving about it.
After researching the differences in price and hardware between the two, and reading a bunch of online reviews, I ended up purchasing the Asus Zenbook UX533FD, and I couldn’t be happier.
It’s super light, has a 10 hour battery life, runs the latest Ubuntu (after a bios update), and is powerful enough that I feel as productive using the laptop as I do on the desktop. At the same time, I also upgraded my laptop mouse to the Logitech M720 Triathlon, the big brother of the Marathon mouse I use on my workstation, and it’s a great wireless addition to the laptop.
The bleeding edge of operating systems.
The other big change I made at the tail end of this year was upgrading both my laptop and workstation OS to the latest version of Ubuntu, 19.10, codenamed Eoan Ermine. I typically only run the latest LTS version on my workstation, and whatever is the latest release on my laptop, but the 19.10 release is so slick, stable and fast that I had to install it on the workstation. I was actually feeling left behind whenever I switched from laptop to PC.
The future
Looking ahead, I don’t think there will be much I will change in 2020, as I’ve pretty much got my perfect set up. But who knows, upgrading computers is the one hobby I do tend to like to spend money on, so I can’t make any promises.
Last night I gave a talk at the Cape Town PHP Meetup introducing the concepts of testing an existing Laravel application. As I did not have time to prepare slides, here are the links to the relevant items I discussed in the talk.
Confident Laravel (course, highly recommended)
Grumpy Learning (course and books, also recommended)
Laravel HTTP tests documentation
This morning I presented a workshop at WordCamp Johannesburg.
Here are the slides for that workshop
Here is the GitHub repository
If you want to see the updated plugin code, with the security fixes, you’ll need to switch to the feature/more-secure-plugin branch.

The Process of Writing
The general recommendation to becoming a better writer, is to write every day.
Besides high school creative writing, I am mostly a self taught writer. I’ve never completed any official copy-writing courses, even though I have three purchased on Udemy from about 2 years ago. I generally don’t understand the finer details that would take me from being a blogger or writing contributor to the ranks of editing someone else’s writing work.
That being said, since I was accepted as a freelance contributor on the Skyword platform early last year, I’ve probably completed at least two written assignments per month. I’m definitely writing more than I ever have, and it’s definitely paying off. I’m seeing the benefits not only in my paid writing work, but also in the general content of my blog.
I thought that it might be useful to share the process I follow, when I am writing content for money. If nothing else, it allows me to write something else today 😉
Brain vomit
While the image above my not be pleasant, this is always my first step. When working on a specific assignment, I will have certain guidelines I need to follow, in terms of article content.
I’ll create a new blank Google Doc, paste any relevant information from the assignment at the top of the page, and then just type out whatever comes to mind. This is usually just a few words or phrases, maybe a title, or a sentence or two.
Research
Once I’ve put down the thoughts I have in my head about the topic in question, I’ll start doing some research. Often this is to clarify some points of (mis)understanding, or to fill in some gaps in my knowledge. The assignment topic will define how much research I do. If it’s in an area I know little about, I can spend up to an hour researching. As I am researching the topic, I’m starting to put together a plan of how the article will look and what the story is I want to tell.
First draft
I then start writing my first draft. This is just everything as it enters my head. I might make minor edits here or there, but mostly I just write as the thoughts come to me.
Break
This is a pretty important step, but I then take some time away from writing. I find this allows me to think about what I’ve written, if there’s anything else I want to add or take away, and allows me to come back to review what I’ve put down with ‘fresh’ eyes.
First edit
This is the most edit heavy process. I read through the content and do my best to self edit my work, taking out repetitive words, looking for other words or phrases that will convey what I’m trying to say. This is usually where I will also start adding links to relevant content, including images, and generally trimming down the content to fit specific criteria. I may also take out sentences, and sometimes whole paragraphs, that don’t fit into the edited article any more.
Second edit
Immediately once the first edit is complete I’ll start the second, and final, edit. This is where I try to just read the article from top to bottom, as a reader would. Usually this is also where I look for complex sentences and try to uncomplicated them, as well as a more detailed focus on spelling and grammar errors. I will also look at the flow of the sentences and prune them where necessary.
I’m sure my process is nothing new or unique, but it’s evolved over time and I find it works for me.
I’ve been freelancing full time for just over three years now, having spent 10 years developing for either digital agencies or small to medium sized businesses, in various roles.
In the 3+ years since I switched to freelance development, the two sentences that I’ve heard/read the most from clients, and the ones that illicit the most negative responses in me, are:
“This will only take x minutes”
“This will be easy for an experienced developer”
If you are a freelancer, and you’ve been on the receiving end of these phrases, you’ll know what I’m talking about. This post however is not for you, it’s for anyone who has ever said one of these phrases to a developer, or who might not understand why they are so negative.
“This will only take x minutes”
x is usually a variable number, ranging anywhere from ‘a few’ to 30. Sometimes minutes is replaced by hours. Either way, the reason this phrase is so despised by freelancers is that it indicates to us that you think you know more about what we do, than we do.
If you know something will take 5 minutes, that means you understand the problem fully, as well as the possible solutions required to solve it and also which one to apply to solve it within 5 minutes. This means you can do it yourself. And it is therefore a lie, because if you could do something in 5 minutes yourself, you would not be hiring someone to do it for you.
“This will be easy for an experienced developer”
Personally, this one is worse than the previous phrase, and here’s why.
This phrase tells me you understand that I am experienced in my field, that I am knowledgeable, and you recognise that I can fix your problem. What it also tells me is that while you recognise my ability to fix your problem, you don’t value my knowledge enough to pay what it’s going to cost.
What is happening in both instances is that you’re trying to get me to keep my price down, because you think it will be a simple solution and you assume therefore it will be quick to fix. Unfortunately, in most cases, you’re making the same mistakes as the folks who thought that Titanic was unsinkable.
If the problem was a 5 minute solution, you wouldn’t need to hire me to fix it. And my experience, comes with a price. You either value the fact that I am capable of solving your problem, or you are looking for a cheap solution, which usually means taking shortcuts, something that I am not prepared to do.
Successful solutions take time, planning and thorough testing. By making assumptions up front, you are setting the project up for failure, and nobody wants that.
I’ll be the first to admit that I am fairly inexperienced in the practical application of unit testing, or any kind of automated testing. That’s not to say I don’t understand what these things are. I was first exposed to the concept of unit tests back in 2008 and automated browser testing in around 2012. I know the theory of how they work and what the benefits are. It’s just that I’ve never been in a situation where I had the time to learn how to implement these things, so I’ve never really been able to. It was the classic “running alongside your bike” scenario.
That being said, there is something that a very skilled developer I used to work with said to me back in 2012, which I’ve implemented ever since, that I only realised today not only applied to writing better code, but also to writing testable code:
“Every function, or class method, should only do one thing”
Shaine Gordon, CTO at Realm Digital
Let me explain that by means of an example.
Let’s say you need to write a string parser. The parser needs to take a string, convert it to lower case, strip out specific punctuation (full stop, comma and space) and return the string with the first character as upper case.
In PHP, that could look something like this:
function my_string_parser( $string ) {
$string = strtolower( $string );
$string = str_replace( array( ' ', '.', ',' ), '', $string );
$string = ucfirst( $string );
return $string;
}Now, the perceptive amongst you might notice the bug. If you don’t see it right away, that’s OK, because that’s the point of this article.
So lets say I now decide to write a unit test to test this function (we’re not digging into TDD just yet). With PHPUnit installed, I might write a test class method that looks something like this:
function test_my_string_parser() {
$string = 'My test, string.';
$parsed_string = my_string_parser( $string );
$this->assertEquals( 'Myteststring', $parsed_string );
}Based on the code above, this test would fail. My problem is, at what point in manipulating the string, does my function fail?
However, if I refactor my initial code a little:
function my_string_parser( $string ) {
$string = my_string_to_lower( $string );
$string = my_string_remove_punctuation( $string );
$string = my_string_ucfirst( $string );
return $string;
}
function my_string_to_lower( $string ) {
$string = strtolower( $string );
return $string;
}
function my_string_remove_punctuation( $string ) {
$string = str_replace( array( ' ', '.', ',' ), '', $string );
return $string;
}
function my_string_ucfirst( $string ) {
$string = ucfirst( $string );
return $string;
}Granted, it’s a lot more code, but now I can write individual tests for each smaller ‘my_string’ function, and the failing test(s) will point to where the bugs are. I can then fix those bugs, function by function, until my individual tests pass, and then the ‘test_my_string_parser’ test will also pass.
I’m pretty sure this isn’t rocket science, or anything new, but if you’re starting your unit journey, it’s a good place to start.
At WordCamp Europe 2019 in Berlin, I was accepted to present a workshop, which was on the WordPress HTTP API.
Unfortunately we had some WiFi issues, and not all the attendees were able to complete the workshop. Also, there were some folks who were not able to attend at all, due to the workshop being booked out!
This post attempts to solve both problems, by including a link to the GitHub repository, the slides, and 3 videos of me live coding (more or less) the workshop content.
Fair warning, this is the first time I’ve done something like this, so bear with me.
Hopefully using the slides, the GitHub repository and the videos, you’ll be able to complete the workshop and learn a little more about working with web based APIs and WordPress.
You can find the GitHub repository here
Below are the videos I’ve recorded of me completing the workshop content.
I don’t think I completed my year end review for 2018 or wrote a resolution post for 2019. However a bunch of things have happened so far this year, mostly in the past few months. As it’s almost exactly halfway through the year, I thought it might be cool to share them.
As one door closes…
Towards the end of last year, my wife and I decided to sell the family business we’d been running together since 2011. It was a hard decision to make, but as our boys were growing older we found ourselves less and less inclined to want to work on weekends, which the business required. I’m happy to say that we successfully sold the business earlier this year.
Castos and accelerator funds
Back in December of 2016 Craig Hewitt contacted me looking for someone to help him extend the podcasting plugin he had recently acquired. I’ve been working with Craig ever since, and so I was very pleased to find out the Castos, the company built to support and enhance the plugin was accepted into the TinySeed Accelerator. Which brings me to…
…another opens.
The investment Castos has received has allowed Craig to offer me a full time role in the company. I’ve been the designated lead developer of the project since pretty much just after we launched what was then called Seriously Simple Hosting back in 2017, but now it’s an official position, with all the benefits and responsibilities that go along with it. I couldn’t be happier, because I think we have a great product, and I now get to work with a small group of amazing people, helping our clients and plugin users from all over the world, every day, so I’m looking forward to what the next year holds for us all.
That’s not to say that I won’t be able to continue to work with my clients at Codeable. I’m lucky to have made great relationships with a group of repeat clients and I will continue to serve them in whatever capacity they require.
This position will also give me some security and time to to put into other areas, including expanding my contributions to WordPress, and getting back on the ‘building my own products’ train. Watch this space.
Castos goes to WCEU
Part of the Castos/TinySeed news was that I was able to travel to Berlin and (finally) meet both Craig and fellow Castos developers Danillo and Stefan. It was the first of what looks to become a regular, yearly team retreat. Working along side people remotely in a start up environment is a fun-filled experience, but there’s nothing like actually meeting in person. We know also know who the tallest member of team Castos is, and no, it’s not me! I’m hoping that the next team retreat will include the other members of our team.
The team retreat was timed to coincide with WordCamp Europe, which meant I was able to attend this year again. My favourite thing about WCEU is meeting people in real life, especially those I’ve only ever meet online. It’s always great to see my community team friends, but this year I was able to connect with, and meet in person, an entire years worth of ‘online only’ folks.
Highlight’s of WCEU 2019 was being able to secure a 15 minute chat with Matt Mullenweg, the Codeable experts dinner and group photo, and Monique Dubbelman bringing me some amazing and authentically Dutch stroopwafels, which I now have to find a supplier for locally.
Professionally, 2019 is shaping up to be a pretty awesome year. I have some plans of things I want to accomplish for the rest of this year and the next, but I’m also acutely aware that one cannot succeed at everything. Win or loose, I’m exceptionally excited to be able to at least try.
