Because Laravel comes with excellent scheduling functions out of the box, artisans don't need to edit the crontab often. If you need to do some scheduling manually, here's a little site that can help you write a cron scheduling expression.

As a user I've pretty much turned my back to Facebook, but boy must it be interesting to work at that scale. Here's how Facebook built their mobile device lab.
... We needed to be able to run tests on more than 2,000 mobile devices to account for all the combinations of device hardware, operating systems, and network connections that people use to connect on Facebook. Today, in our Prineville data center, we have a mobile device lab — outfitted with a custom-built rack — that allows us to run tests on thousands of phones. The process of building a lab in our data center wasn't a direct path, and we learned a lot along the way...

Frank De Jonge, member of the PHP League and author/maintainer of Flysystem, was facing a world of pain with ElasticSearch. Luckily the story has an happy ending. Read all about his journey on his blog.
For a client project we are using ElasticSearch (ES) as one of our read-models. The use-case was pretty straight forward and the amount of data was super small. However, our problems were pretty big. It got to a point where we had to reboot our cluster periodically to prevent it from crashing. So, what was going on? Let's dig in.

In a new post on his blog Thijs Feryn explains type errors and strict types, both introduced in PHP 7.
PHP 7 has a concept called Type Errors. These errors are thrown on a type mismatch when interacting with functions. They can be caught just like exceptions. I created a video that explains the situation. This blog post goes into more detail and has some code examples.
Fred Hébert on his blog:
... sooner or later, people start misinterpreting the original intent and thinking of technical debt the same way you could think about financial debt: a lever to use in order to get something now and then pay the accrued cost progressively over time. This is however not how things feel from the technical person's point of view. ... Rather than focusing on why that is wrong, I want to propose an alternative analogy to describe the reality behind technical debt.
Rob Allen, an active member of the Zend Framework community, makes the case for giving some love to API errors.
It's not hard to have great error responses; you just need to care. Poor error response cause developers to give up with an API and go elsewhere, so it's a competitive advantage to get this right.Developers integrating with your API will thank you.
Nicolas Widart, author of Asgard CMS, created a new package called laravel-modules that can help splitting up a large Laravel app in modules.
On his blog he published an introductory post.
Just imagine having a medium sized application where everything is in the `app/ù folder, worse, every model is in the root of the app folder! At some point you will spend a lot of time looking for things because everything is bunched together.This is what being modular is trying to resolve. You split of the business logic into different parts, which belongs together. If you're into Domain Driven Design, you can consider a module an aggregate.
Every module has its own routes/controllers/models/views/business logic/etc. Meaning every module contains a group of classes that all are related to each other in some way.

In my book Joseph Silber is one of the unsung heroes of the Laravel ecosystem. Whenever I open up internals on Larachat or Github he's giving friendly and thoughtful advice. I was happy to learn that Joseph started a blog.
In the first post he goes over all the improvements made to authentication in Laravel 5.3.
Authentication has gotten some nice improvements in 5.3, so let's examine it piece by piece.
- Introducing the authenticate method
- The exception handler's unauthenticated method
- The Authenticate middleware
- Authenticating against multiple guards
- Route model binding and global scopes
- Bonus: the request's expectsJson method

Laravel 5.3, which will be released at this years Laracon US, has some new very handy functionality to work with MySQL 5.7 JSON columns. In a post on his site Matt Stauffer demonstrates the new API.
While Laravel has had the ability to cast your data to and from JSON since version 5.0, it was previously just a convenience—your data was still just stored in a TEXT field. But MySQL 5.7 introduced an actual JSON column type.Laravel 5.3 introduces a simple syntax for lookups and updates based on the value of specific keys in your JSON columns.

If you're going to use this functionality, you should also read Mohamed Said's post on how to improve performance by using MySQL generated columns.
JSON columns cannot be indexed. You can work around this restriction by creating an index on a generated column that extracts a scalar value from the JSON column.

In a post on his site Mattias Geniar shares how to write for loops in Bash.
Let me first start by saying something embarrassing. For the first 4 or 5 years of my Linux career -- which is nearing 10 years of professional experience -- I never used loops in Bash scripts. Or at the command line.The thing is, I was a very fast mouse-clicker. And a very fast copy/paster. And a good search & replacer in vim and other text editors. Quite often, that got me to a working solution faster than working out the quirky syntax, testing, bugfixing, ... of loops in Bash.
And, to be completely honest, if you're managing just a couple of servers, I think you can get away with not using loops in Bash. But, once you master it, you'll wonder why you haven't learned Bash for-loops sooner.
Every single day I use Sequel Pro to manage MySQL databases for all projects I'm working on. Sequel Pro gets used in both development and production environments. Because the databases mostly have the same name and tables in all environments it's very easy to mix them up. You have to be really…
Tighten has developed a very useful package for testing mail in Laravel.
Ross Tuck gave a one of kind closing keynote at this year's (excellent) Dutch PHP Conference. Clear your schedule for the coming hour and watch the video of the talk with full attention. It's really great.
At the conference there were a lot of talks on events sourcing. The two talks with that subject that stood out for me were Shawn McCool's (where he applied event sourcing to the board game Quantum), and Greg Young's opening keynote. Watch the latter one here:
Jordi Boggiano investigated if there are pundits actively abusing typos in package names.
Earlier this month an article was published summarizing Nikolai Philipp Tschacher's thesis about typosquatting. In short typosquatting is a way to attack users of a package manager by registering a package with a name similar to a popular package, hoping that someone will accidentally typo the name and end up installing your version of it that contains malware.... I wanted to take a look at our repository data and see if I could spot any bad actors.
From time to time I need to process a csv file. PHP provides a fgetcsvfunction to help with that task. Unfortunately this is a very basic function. It will not, for instance, recognize a header column as such. In this quick post I'll show how using the excellent laravel-excel package (which can…
In your apps there's probably a lot going on. Users log in and out, they create, update and delete content, mails get sent and so on. For an administrator of an app these events provide useful insights. In almost every project we make at Spatie we log these events and show them in the admin-section…
Bill Sourour has some good tips on how to manage your time.
There’s no time for anything. At least that’s how it feels doesn’t it? No time to learn all the things you think you need to learn to stay ahead of the curve. No time to go back and refactor that ugly piece of code. It works (sort of) and there’s a deadline approaching. No time to write unit tests for everything. No time to write documentation or comments for the next guy who gets stuck maintaining what you wrote. No time to think. No time to breathe. No time!Well… if you take the time to read this article, I promise you’ll find yourself with more time for what’s important.

All sites owned by EU citizens or targeted towards EU citizens must comply to a crazy EU law. This law requires a dialog to be displayed to inform the users of your websites how cookies are being used. You can read more info on the legislation on the site of the European Commission. The newest Laravel package made by my colleagues at Spatie and myself makes your app compliant with that law.
Once installed the package will render the following dialog that, when styled, will look very much like this one:
When the user clicks "Allow cookies" a laravel_cookie_consent cookie will be set and the dialog will be removed from the DOM. On the next request Laravel will notice that the laravel_cookie_consent has been set and will not display the dialog again.
We've made it easy to customize the texts shown by the dialog. You can also make changes to the dialog or JavaScript itself.
The legislation is pretty very vague on how to display the warning, which texts are necessary, and what options you need to provide. This package will go a long way towards compliance, but if you want to be 100% sure that your website is ok, you should consult a legal expert.
Take a look at the package on GitHub to learn how to install the package and which options it provides. If you like it, be sure to check out our full list of Laravel packages.
Joeri Verdeyen, a developer at Yappa, explains how you can use some Symfony components in a legacy application.
Symfony Components are a set of decoupled and reusable PHP libraries. They are becoming the standard foundation on which the best PHP applications are built. You can use any of these components in any of your applications independently from the Symfony Framework.The purpose of this post is to roughly describe how to implement some of the Symfony Components.
