As the joke goes, “there are 2 hard problems in computer science: cache invalidation, naming things, and off-by-one errors.” In this article, we’ll skip over why computer science only has one joke and instead focus on what makes cache invalidation “hard” and demonstrate how it can be solved in the context of a content management system.
Insights to the world of content management.

Blitz 4.3 Feature Release
Blitz 4.3 has been released and it packs some important features including a dashboard widget, new include functions with SSI and ESI support, as well as a PHP equivalent of server rewrites. In this article we’ll run through when and why you might want to use each of them.

Load Testing Craft CMS
The Performance Testing Craft CMS with Blitz article sparked intense discussion among colleagues, especially the observation that Craft CMS demo site we used barely managed to serve 3 successful requests per second without caching. In this article, we collect the most thought-provoking ideas and attempt to address them with, you guessed it, more load tests!

ExpressionEngine Add-ons Acquired
We’re pleased to announce that our last remaining ExpressionEngine add-ons, Sitemap and Snaptcha, have been acquired by BoldMinded. This marks our complete exit from the EE ecosystem.

Performance Testing Craft CMS with Blitz
We invited an independent contractor to measure the performance of a Craft CMS demo site and the impact of using Blitz, paying for their time and agreeing to publish their words without further influence or agenda. This is what they wrote.

Overview of Security Best-Practices
I was recently invited to give a presentation on my thoughts about security best-practices for the Charlotte Craft CMS Developers Group. I ended up giving a high-level overview of what I believe are the most important things everyone must understand in order to build secure sites and software.

Gone Phishing, Catch you Later
Stanford University runs a Phishing Awareness Program that aims to train participants in how to recognise, report and avoid phishing attacks. Given that email is the entry point for 91% of cyber attacks and therefore every organisation’s biggest vulnerability, perhaps we can all benefit from increasing our phishing awareness.

Adding Logging to Craft Plugins with Monolog
Logging plays an essential part in leaving an audit trail of what events take place in a CMS. Monolog is a logging library that ships with Craft CMS 4, which can be customised to make logs easier to read and parse when used in plugins and modules.

Requiring a Forked Repo with Composer
If you ever find yourself having to modify a Craft plugin, or any composer package for that matter, then you can do so using a fork. A fork is a copy of a repository that you manage. Forked repositories let you make changes to a package without affecting the original repository.

Building a RESTful API in Craft CMS
There are times when you want to make data and actions in Craft available to external services. Fortunately, Craft’s URL manager (or more accurately Yii’s) makes handling the routing of requests straightforward, so you can define and route your API endpoints with just a few lines of code.

Securing Your Craft Site in 2022—Part 3
The infamous Murphy’s Law states that “Anything that can go wrong, will go wrong”. Having an up-to-date security policy helps ensure that there are steps in place to prevent a catastrophe and that you can react responsibly if and when things do go south.

Ballroom Blitz
After 2 years and over 2,500 active installs in the plugin store, we’ve decided that the time is finally right to bring templating performance hints, previously provided by the Blitz Recommendations plugin, directly into Blitz. There is now no excuse for not eager-loading elements in your Twig templates, as the new utility keeps track of opportunities as pages are visited and tells you about them!

Plugin Roadmap 2022
With the release of Craft 4, we’re rolling out major version releases of all our plugins, including some big features in Blitz and Campaign. Our release schedule will fall into step with that of Craft CMS, as will our maintenance and support periods.

A First Look at _hyperscript
_hyperscript is a scripting language for adding interactivity to the front-end. You guessed it, yet another JavaScript library. But what makes hyperscript unique is that it provides a natural language syntax for optimal readability, reusability and maintainability, arguably the most important qualities of any “programming” language.

Common Security Vulnerabilities in Craft CMS Plugins
I’ve said it before and I’ll say it again: never trust user input. This is one of the golden rules of security, yet when designing plugin APIs, we often tend to favour flexibility over restriction, which can get us into trouble if we are unaware of the data or endpoints we are exposing.

Bridging the Phases of a Web Project, with Kyle Cotter of Happy Cog
I recently sat down with Kyle Cotter, Author Experience Lead at Happy Cog, to hear about the process of building and launching Canary Media on Craft CMS. It turns out that the bridging of the discovery, design, development and DevOps phases is what stands out as the most intriguing thing about this project. And by the end of it, Kyle has me convinced that a successful project is one in which each phase receives the attention it needs, the tasks are rigorously prioritised and the features that make it into launch and those that don’t are, once decided, indisputable.

Storing Secrets in Craft CMS
The most secure way of preventing secrets from being revealed is, well, not storing them at all. But assuming you need to access sensitive secrets in your PHP code, such as credentials to an online bank account, then storing them encrypted is much more secure than in plaintext.

Leveraging Craft CMS Plugins for Horizontal Growth
Having spent a decent portion of my career building client sites, one thing that always struck me as dangerous was the unsustainable cycle that web agencies tend to fall into. Chasing the next big project, rather than producing the best quality work, often becomes the primary objective of stakeholders. Avoiding this trap is possible by focusing on “horizontal” growth and one way to do this is by leveraging plugins.

Securing Front-End User Profile and Entry Forms in Craft
Every Craft site that allows public registration implicitly grants its users elevated privileges. Specifically, users have the ability to update all custom fields on their profile, as well as in any entries that they have permission to edit. If you use custom fields for “private” admin use only, then you may be leaving your site open to abuse.

Snaptcha 3 Released
Snaptcha 3 adds more control over which form submissions and users to validate, as well as a fail-safe method for dealing with false negatives (submissions that are incorrectly believed to be spam).

PHP 7.3, 7.4 and 8.0 Security Release
If you host any sites on a VPS that you manage then this PHP security update very likely affects you. The severity of the update is unclear, but fortunately, it is a simple patch.

Securing Your Craft Site in 2021—Part 2
Using software you trust is key to increasing your chances of keeping your site secure and lowering the chances of introducing a vulnerability. But how exactly do you know which software (and developers) are trustworthy and which are not?

Stepping Up Security with Sherlock 3
Security is one of those things that can be difficult to prioritise on a client project. Today we released Sherlock 3 which aims to change that. It’s time to start taking security seriously.

Securing Your Craft Site in 2021—Part 1
Cybersecurity often feels like another world, yet in recent years it’s a topic that I’ve become mildly obsessed with. As web and software developers, security is an integral part of what we do, but for the most part it is self-contained in terms of the code that we work on directly. That has to change.

Sprig 1.1.0 adds Features & Security
Sprig 1.1.0 adds new features as well as some important security improvements. Most notably, Sprig now uses htmx 0.4.0 and adds template variables to paginate element queries, push URLs into the history stack, redirect and refresh the browser, trigger client-side events and more securely add values to a request.

Sprig and the Joy of HTML
I love the simplicity of HTML. Take a web site from 1999 and it will still render in a modern web browser. Sure, it will look antiquated, but it will work. HTML is the backbone of the web and it is making a comeback as a language.

Takeaways from Dot All in Montréal
Dot All 2019 recently wrapped up and it did not disappoint!! Dubbed “the JAMstack conference” by attendees, there were some big announcements like Craft CMS 4 and Craft Cloud. All in all though, this conference was about the people, their stories and the community.

How The Web Moves On, And Doesn't
Today we are overjoyed to launch a new major redesign. Huge thanks to Seamus Holman, Sarah Waring and Jana Grabner for helping to make this a reality!!
8 years ago today we revealed our first major redesign to the PutYourLightsOn brand. To my surprise, while taking a trip down memory lane, I realised that even though the web has really moved on since then, design really hasn’t that much.

A Technical Rundown of How Project Config Works
As of Craft 3.1.0, “Project Config” is a thing. Here’s a technical rundown of how it works.

Understanding Project Config in Craft CMS
Craft CMS 3.1 introduces some big features, most noticably Project Config. Project Config is a configuration setting which, when enabled, turns a .yaml file into the single source of truth for a site’s schema.

Static File Caching with Craft CMS 3, aka The Best Of Both Worlds
In a recent redesign of the PutYourLightsOn website, we decided to start with a blank slate. It became an excellent opportunity to re-evaluate the state of web publishing tools in 2018 with the aim of utilising the best possible means to build a lightning-fast site that would still enable a great authoring experience.

Upcoming ExpressionEngine Conference
In just a few days I will find myself amongst my peers at the biggest ExpressionEngine event of the year, and I couldn’t be more excited about it. A lot has happened in the CMS world over the past year and I feel that the conference is a great way to come to terms with some of these changes and to “check in” with the community and with the team behind EE.

Craft Plugins Launched
Today marks the beginning of an exciting time for us. We have just taken 2 of our Craft CMS plugins, Snaptcha and Sitemap, out of private beta, and the 1.0.0 releases are now available.

Add-on Support Visualised
Lately I’ve become more aware of a pattern that seems to be quite common among software within the ExpressionEngine community, and it not only appears within third-party add-ons but stems all the way from the core product itself.

Multi Language Module Now Free For Everyone
The Multi Language Module has been free for non-profit organisations since it’s release nearly 4 years ago, but as of today we are making it a free add-on for personal and commercial use as well.

Why I’m So Excited About Craft (and why you should be)
In the past couple of weeks I’ve spent more and more time playing with Craft, the new CMS by Pixel & Tonic. When I say playing with, I mean working with, but since it is proving to be such a joy to use, I feel that “playing” is a more appropriate word.

EEUK & Open API Revealed
I had the pleasure of revealing Open API, my latest creation for ExpressionEngine, in my presentation at EEUK 2013. Open API is a front-end, http-based API for ExpressionEngine that provides authentication and CRUD (create/read/update/delete) functionality to content and data in the CMS.

End of Year Round-up
2012 seems to have flown by rather quickly but it has been an action-packed year. We released three add-ons this year, two of which have been nominated for the devot-ee AcademEE Awards. We attended EECI Europe and I had the honour of speaking at EECI U.S.

EECI US 2012
I was lucky enough to go to both EECI’s this year, the European one in Leiden and the US one near Austin which happened last week. In fact I was invited to speak at the US one and felt very honoured to present to my fellow EE community members. I gave a talk on the developer’s track and it was a full house, standing room only!!

Visualising Devot-ee Sales
If like me you sell your ExpressionEngine add-ons on devot-ee then you are definitely familiar with the sales reports page. It gives a quick overview and tabular report of the selected month’s sales. But if you want to properly analyse your sales then you simply need to visualise them. I’ve written a small php script to do just that and frankly I’ve surprised myself with how insightful it is.

Responsive CP Finally Released
Responsive CP is an ExpressionEngine theme that I started working on over a year ago but that I only released to the public as a free add-on last week. You may have already noticed it in the various screenshots of our add-ons. The theme has two main goals – to provide a more professional looking control panel and to work well on desktop as well as mobile devices with small to medium screen sizes.
