1. Google ARCore ARCore is Google’s tool for augmented reality (AR) app development. ARCore uses various APIs to help the user’s device track its motion and position, understand and detect its environment and estimate the environment’s lighting conditions. The tool’s lighting detection means your virtual object can be lit under the same conditions as its environment, and its ability to detect vertical and horizontal feature points allows you to place virtual objects on flat planes. ARCore is platform-specific to Android, meaning you’ll have some work ahead of you to make your AR experience work cross-platform. Pricing: Free 2. Apple ARKit 2 ARKit 2 lets you provide AR experiences that allow multiple users to participate simultaneously. It also allows users to stop the app and resume it later in the same state. In addition to 3D object recognition, ARKit also supports 2D object recognition for items like posters or signs. The limitation of ARKit, like ARCore, is that it’s platform specific, working off Apple’s native XCode codebase. Pricing: Free 3. Wikitude Wikitude works cross-platform to create AR experiences for Android, iOS or Windows. You can use Native or JavaScript, or Unity, Cordova or Xamarin to create a seamless AR experience for phones, tablets and smart glasses on all three supported operating systems. Wikitude can augment multiple images simultaneously and can also recognize, track and augment 2D images. Pricing: Subscription plans range from around $2,800 USD/year to more than $5,000 USD/year. 4.

Hey, how are you doing? In this article, I’m going to show you how you can install Laravel 8 on your phone. To get the most out of this guide, you should have some knowledge of PHP and you should know what Laravel is. But if you don’t, don’t worry – I will explain the basics so you can get started. What Is Laravel? Laravel is a web application framework with expressive, elegant syntax. It’s built on PHP, which means that Laravel is PHP but it makes things easier to work with. It comes with lots of packages for various features, like authentication, so we don’t need to write authentication ourselves. To learn more about what Laravel can do, you can visit the site at laravel.com. Why I wrote this tutorial I created this tutorial because I want people interested in programming who don’t have a laptop or pc to be able to build things on their phones. My last post on freeCodeCamp made me realize that people are interested in learning how the tech works, so that’s why I’m making more guides like this. So let’s dive into it. In this tutorial I am going to show you how you can install composer.php and use it to set up Laravel 8 on your phone 🔥🔥. I am Precious Oladele, and I’m almost 19 this month 🥴. I’m from Nigeria and I will be taking you through this process. And if you’re wondering how I know so much about this, it’s because I also don’t have a laptop so I explore with my phone instead 😎.

If you have some experience using databases, it is very likely you have used joins at least once in your career. Joins can be used for a bunch of different reasons, from selecting data from other tables to limiting the matches of your query. I’m going to give a few examples on this post, so, in order to contextualize the examples, imagine we have the following database/models structure. User -> hasMany -> Post Post -> hasMany -> Comment Post -> morphMany -> Image On Laravel, using eloquent, joining the posts table would look something like this: In case you want to join the posts and the comments table, your query would look something like this: This is fine and we can understand, but we can do better. We already have all these relationships defined in our models, but we are repeating some of the implementation details when we write the join statements. So, instead of doing this, wouldn’t be cool if you could just do the following? This is less code to read, and more importantly, easier code to read. It also hides any implementation details on how your relationships work. So, if your relationship changes, your joins will be automatically updated. Introducing the Eloquent Power Joins package We felt the way we did joins in our applications wasn’t really the “Laravel way”, so we decided to introduce some of the Laravel fine touch into the way we do joins. joinRelationship is a method introduced by the Eloquent Power Joins package. It works with any type of the existing Laravel relationships. The installation of the package is as simple...

Async processing of long-running tasks in ASP.NET Core Written by Thomas Ardal, September 14, 2021 Sometimes, invoking an API endpoint needs to trigger a long-running task. Examples of this could be invoking an external and slow API or sending an email, which you don’t want the caller of your API to wait for. There are multiple ways of implementing this using a message broker, a fire and forget API request, or something completely third. In this post, I’ll show you how to implement async processing in ASP.NET Core, using a queue and the Background Worker feature. To understand how to process long-running tasks, let’s start by creating an example and making it sloooooow. Create a new ASP.NET Core application through Visual Studio, dotnet, or your preferred scaffolding engine. For this example, I have chosen the MVC template, but it could just as well be one of the other options. Next, in the HomeController.cs file, create a new method to simulate a call to a slow running task: For the demo, I’m waiting 10 seconds to simulate some work. The Task.Delay line would be replaced with some integration code in a real-life example. I have wrapped the code in information messages, which I can later inspect in Visual Studio or through the configured logger (maybe elmah.io?). Then, invoke the CallSlowApi method from the Index method: Let’s run the application and inspect the performance in Developer Tools: As expected, loading the frontpage takes just above 10 seconds (10 seconds for the Task.Delay and 30 milliseconds to load the page). Refactoring time! To process the message asynchronously, we’ll implement a background worker...
