– christoph-rumpel.com

Christoph Rumpel wrote a clear post on how you can use Laravel's service container.

The service container is a quite complex topic, and I see many struggling to understand what it does. It was the same for me, and the main reason is that many explanations concentrate on "how" to use the container. With this article, I want to give you my introduction to this topic by focusing on the "why" and "when" the container can help us with our dependencies.

NASA's JPL, which is responsible for some of the most awesomest science out there, is quite famous for its Power of 10 rules (see original paper). Indeed, if you are going to send a robot on Mars with a 40 minutes ping and no physical access to it then you pretty damn well should make sure that your code doesn't have bugs.

Laravel and Murphy’s Law

– medium.com

Patrick Brouwers, the creator of Laravel Excel, explains how to handle failing jobs in Laravel

When designing software, don’t only think about the happy path. Write down (preferably with (unit) tests) what all the things are that could go wrong. Then design your solution to be able to recover those situations. (Wether or not automatic.) There isn’t a single solution to rule them all, some processes might need to have specific failure handling while others are fine with the default approach.

Laravel Vapor uses different AWS resources to efficiently get your application up and running in the serverless cloud. The building block of the whole thing is AWS Lambda, it's where the actual computing happens.

Viewing model counts in the Laravel Debugbar

– reinink.ca

Jonathan Reinink has added a very usefull metric to Laravel debugbar

Last week at Laracon US I gave a talk titled Eloquent Performance Patterns. In that talk I used a custom Laravel Debugbar metric I created to track how many Eloquent models were being hydrated throughout a request. I've had a lot of people asking about this, so today I submitted a pull request to the Laravel Debugbar to add this as an official metric.

Why Build X When Y Exists?

– davidhemphill.com

In a new post David Hemphill argues that you sure can (re)build something that already exists. I fully agree.

Some folks ask this rhetorically, implying there's no good reason when something similar already exists. They ask this question with a smug grin and think they've got you.

There’s more than one way to write an IP address

– ma.ttias.be

Mattias Geniar explains all the ways an IP address can be written.

Most of us write our IP addresses the way we've been taught, a long time ago: 127.0.0.1, 10.0.2.1, ... but that gets boring after a while, doesn't it. Luckily, there's a couple of ways to write an IP address, so you can mess with coworkers, clients or use it as a security measure to bypass certain (input) filters.

Run and stop multiple long-running commands from Bash with a trap

– liamhammett.com

Liam Hammett explains how you can use the trap command to stop multiple bash process in one go.

Sometimes when working on a project, I’ll always want to run a handful of commands at the same time, some of which may return when they’re done, others might be long-running, like watchers or services actively exposing ports. This is something that might seem simple to do with a basic Bash script at first, but what if your script has multiple processes running side-by-side and you want to be able to stop them all at once too?

Domain Events vs. Event Sourcing

– www.innoq.com

Christan Stettler wrote an interesting post on why domain events and event sourcing should not be mixed up.

Event sourcing and domain events can of course be used both at the same time, but should not influence each other. The two concepts are used for different purposes and should therefore not be mixed.

Implementing event sourcing: testing aggregates original

by Freek Van der Herten – 4 minute read

Earlier this year we released v2 of laravel-event-sourcing. This package is probably the easiest way to getting started with event sourcing in Laravel. A significant feature of v2 was the addition of aggregates.

Today we released another new version of the package that adds test methods. These methods allow you to verify if the aggregate behaves correctly. In this post, I'll show you an example and explain how the test methods are implemented.

These test methods were inspired by the awesome testing methods Frank De Jonge made in his Eventsauce package.
