Generating IDE Stubs for IonCube-Encoded Classes

Here's a great story by Collin O'Dell, maintainer of league/commonmark amongst other things, on how he was able to extract the class definitions out of obfuscated PHP source files.

Per the framework's license, decrypting the IonCube-protected code was not allowed. This meant it was impossible to recover the original source code. However, I could require those files and execute them in PHP, which would cause those classes to become usable in code. So how does one figure out what code just got loaded & executed?

Theme-based views in Laravel using vendor namespaces

At Spatie, we're building a multi-tenant app. Seb figured out a great way to handle theme based views.

Laravel allows you register a view vendor namespace which points to a specific directory containing Blade files. This feature is intended for package development, but it's a perfect solution to our problem.

By registering a namespace with the current theme's location, we can drop all the dynamic parts of our view names when we're calling them.

Open-sourcing our guidelines original

by Freek Van der Herten – 7 minute read

At Spatie we recently launched a new site: guidelines.spatie.be. It contains articles on how we go about setting things up at Spatie and a collection of styleguides. The source code of the site is available on GitHub. In this blogpost I'd like to share why and how we created our guidelines site. Why…

Use your Laravel named routes in JavaScript

Daniel Coulbourne, an engineer at Tighten Co and co-host of the amazing Twenty Percent Time podcast, recently released Ziggy, a tool to share your Laravel named routes with JavaScript.

Ziggy creates a Blade directive which you can include in your views. This will export a JavaScript object of your application's named routes, keyed by their names (aliases), as well as a global route() helper function which you can use to access your routes in your JavaScript.

Laravel/MySQL JSON documents faster lookup using generated columns

In an older post on his blog Mohamed Said demonstrates how you can leverage virtual columns to speed up queries on data stored as JSON.

Laravel 5.3 is shipped with built-in support for updating and querying JSON type database fields, the support currently fully covers MySQL 5.7 JSON type fields updates and lookups,

...

Let's see how we may create a generated column to store users favorite color for later indexing.

Using global mixins in Vue.js original

by Freek Van der Herten – 2 minute read

Recently I needed to add some global functionality to nearly all Vue components in an app. My colleague Seb told me a good way to achieve this: global mixins. In this post I'd like share that knowledge. In Vue a mixin is some functionality bundled in a file that can be added to one or more Vue…

CSS Utility Classes and "Separation of Concerns"

In my day to day work I don't write any css at all, but I still very much enjoyed this blogpost by Adam Wathan where he shares some interesting things about how css should be structured and he makes the case for using utility classes to make visual tweaks.

When you think about the relationship between HTML and CSS in terms of "separation of concerns", it's very black and white.

You either have separation of concerns (good!), or you don't (bad!). This is not the right way to think about HTML and CSS. Instead, think about dependency direction.

...

One of the biggest benefits of using small, composable utilities is that every developer on your team is always choosing values from a fixed set of options.

The disadvantages of single page applications

Adam Silver lists a bunch of problems you need to solve if you opt to build a single page application.

Ironically, SPAs are harder to design and harder to build. And yet, they typically produce slow, disagreeable experiences for users. ... Javascript is never going to beat the browser at what it does best—browsing. We can still give users rich and enhanced experiences without cramming an entire site into one document.

We should let the browser manage the browsing experience, and spend our time solving real user problems.

Precision Through Imprecision: Improving Time Objects

Ross Tuck is probably one of my favourite bloggers. He doesn't publish something often (his previous post is from 2015), but when he does it's very much worth your time.

The important takeaway here isn’t “value objects, yay, inline juggling, boo!” It’s that we were able to remove several classes of errors by reducing the precision of the DateTime we were handling. If we hadn’t done that, the value object would still be handling all of these edges cases and probably failing at some of them too.

Reducing the quality of data to get a correct answer might seem counter-intuitive but it’s actually a more realistic view of the system we’re trying to model. Our computers might run in picoseconds but our business (probably) doesn’t. Plus, the computer is probably lying anyways.

Calculating distance using MySQL

Logan Henson, a developer at Tighten, wrote a new post on the company blog about MySQL's cool ST_Distance_Sphere function.

On a client project recently, we had to make it easy to filter database query results based on the distance between a user and an entity in our database. It's easy to get overwhelmed in that context, worrying about the crazy amount of PHP calculations you're going to have to run. ... If you need to calculate this, you can actually get surprisingly far by just using MySQL!

Language features and code properties

Josh Justice gives some solid advice on how to pick the right language for your next projects.

So to ask the question “should I use an OO or FP language (or style)” is to skip several steps. I think a better series of questions are: First, what properties would be beneficial for your application to have: concurrency? Immutability? Encapsulation? There are a lot of things you won’t know about your application at first, but you can at least know if it will be a backend app, JavaScript browser app, or native mobile app; if it will be CPU-bound or IO-bound; and if it will process data inputted by humans or automatically generated by machines. All of those factors can influence which properties you need.

Once that’s decided, the next question is, in a given language, are those properties guaranteed, easy, difficult, or not realistically achievable?

Why using Yoda conditions you should probably not be

Grégoire Paris wrote down his opinion on why he dislikes Yoda conditions.

So how do Yoda conditions work? Well it is basically a knee-jerk reaction you have to develop: whenever you write a condition, put the operand that cannot be assigned on the left. This should give you an error message if you make an assignment when you actually meant to make a comparison.

https://dev.to/greg0ire/why-using-yoda-conditions-you-should-probably-not

Personally, I'm not a big fan of Yoda conditions either. My feeling is the the cost of decreased readability is just too high for the small value that Yoda conditions bring to the table.

Cruddy by design

At this year's Laracon US Adam Wathan gave a talk titled "Cruddy By Design" on how to structure your controllers better. After the conference he published a new GitHub repo that contains the demo app he refactored on stage. The 4 main tips to improve your code come as PRs on the repo with a full description on why the change is valuable. Very cool stuff.

Using this convention as a "rule" is a good way to force yourself to keep your controllers from becoming bloated, and can often lead to learning interesting new things about your domain.

For the presentation, I put together a demo app called "CastHacker" that showcases podcasts about software development. It's not a "real" app by any means (lots of imaginary features, no tests, etc.); it's just enough code to demonstrate the concepts from the presentation. Feel free to clone it and play with it locally if you like though.

I've written up each refactoring I shared in the presentation as a detailed pull request.
