In today’s post, we’ll learn what gRPC is, when you should reach for such a tool, and some of the pros and cons of using it. After going over an introduction of gRPC, we’ll dive right into a sample application where we’ll build an Elixir backend API powered by gRPC. Let’s jump right in!
If you take a long hard look at the DevOps movement, you will find it actually divides neatly into two sub-movements. The bigger and often noisier of the two is about technology, advocating for the latest and the greatest tools and techniques, be they Cloud, CI/CD, Serverless, or Containers. The smaller sister, however, is much different, stemming from Management Theorem and focusing more on processes.
Finding slow JavaScript code can be a tricky problem to solve. Small code changes can have a big impact on the performance of your code. Fortunately, many different approaches can help you nail down the exact source of the problem. In this post, you’ll learn about three methods that’ll bring you the results you’re seeking. You can trust manual code inspection, but that has its disadvantages.
In today’s post, we will be looking into a software design pattern called Facade. When I first adopted it, it felt a little bit awkward, but the more I used it in my Rails apps, the more I started to appreciate its usefulness. More importantly, it allowed me to test my code more thoroughly, to clean out my controllers, to reduce the logic within my views and to make me think more clearly about an application’s code’s overall structure.
If software's been eating the world for the past twenty years, it's safe to say machine learning has been eating it for the past five. But what exactly is machine learning? Why should a web developer care? This article by Julie Kent answers these questions. I don't have kids yet, but when I do, I want them to learn two things: Whether or not you believe that the singularity is near, there's no denying that the world runs on data.
Rostyslav Kosmirak is a .NET developer from Ivano-Frankivsk, Ukraine using Rider and Visual Studio IDE. Kosmirak was not looking for a Dynamic Code Profiler when he came across Prefix. Kosmirak explains that initially he was searching through Google for a log management system when he stumbled on Prefix. Upon downloading, Kosmirak discovered hidden performance problems in his code before they manifested to actual performance problems.
When it comes to web development, middleware is often the key to ensuring everything connects up - even if some of the pieces don’t always match up. HTTP Middleware is a mechanism used to conveniently filter HTTP requests coming into your web application. When it comes to PHP, frameworks often help us get our applications to handle workloads vanilla PHP might have a harder time managing. Frameworks help to manage the underlying structure of an application while supporting existing PHP standards.
Elixir 1.10 was recently released, and with that release came a little-known, but very interesting feature—compiler tracing. This feature means that as the Elixir compiler is compiling your code, it can emit messages whenever certain kinds of things are compiled. This ability to know what’s going on when Elixir is compiling our code might seem simple, but it actually opens up a lot of doors for opportunities to build customized compile-time tooling for Elixir applications.
If you've been on the hunt for a new developer podcast, then you understand just how difficult and fruitless that pursuit can be. You can spend hours online sifting through coding podcasts, programming podcasts, and DevOps podcasts only to realize one simple thing: none of them focus on your preferred programming language! With thousands of different developer podcasts out there, the problem is magnified exponentially. Fortunately, we at Scout APM have nothing but expertise and time on our hands.
