NodeSource Brings arm64 Support to its Node.js Binary Distributions

NodeSource is excited to announce support for the aarch64 (ARM 64-bit) architecture in Enterprise Linux based distributions! It includes: In the last decade x86_64 was the dominant architecture in Enterprise Linux based distributions, but since 2018 there has been a significant increase in arm64 downloads. Also, big tech companies such as Apple and Amazon are adopting the arm64 processor.

When Debugging Meets Performance

Our ongoing goal at Rookout, the Live Debugging company, is to turn the debugging of live, remote applications into something that every developer can easily do as part of their daily workflow. Recently, we have taken this challenge one step further. What if we could make it so developers were also able to solve performance issues on a daily basis as well? Some recent additions we made to the Rookout platform are the first step towards turning that vision into a reality.

Introduction to Event Loop Utilization in Node.js

In the last year, I've spent many hours writing patches for libuv and Node to collect new metrics. The goal of this was to indirectly infer the state of the application without introducing measurable overhead. I've run a few hundred hours of benchmarks and collected over one million data points to make sure my analysis was correct. Eventually, I plan to write about all aspects of my research, but today we will focus on a metric that has already been added to Node.

Python Memory Management: The Essential Guide

Python is not known to be a "fast" programming language. However, according to the 2020 Stack Overflow Developer Survey results, Python is the 2nd most popular programming language behind JavaScript (as you may have guessed). This is largely due to its super friendly syntax and its applicability for just about any purpose.

"Hello, Ruby Debugging"

Learning a new language is always a joyous event. From the first innocent google search, through the first “hello world”, to always being surprised when the classic text is somehow printed to the screen/command line console/browser tab/local text file. The entire time your mind is quickly soaking in new ideas and concepts, new syntax and phrases, and new ways of doing things. Some of them can be compared to the languages you already know. Others are brand new.

Building a Multi-tenant Ruby on Rails App With Subdomains

According to a definition of multitenancy, when an app serves multiple tenants, it means that there are a few groups of users who share common access to the software instance. An excellent example of an app that supports multitenancy is the Jira platform, where each company has its subdomain to access the software, for example, mycompany.atlassian.net.

Fast & Curious: Find and Fix Slow Queries & API Requests

AppSignal was built because we were tired of slow and clumsy monitoring setups. Instead, we built monitoring that’s easy yet powerful - an intuitive interface enables you to figure out what’s happening in no time. Today, our team made finding slow events effortless. We’ve fully overhauled our slow events feature, helping developers to quickly find and fix slow queries and API requests.

Rest vs SOAP: The Key Differences You Need To Know

When choosing between these two popular web API (application programming interface) formats it can be surprisingly difficult to know which one you should select for your infrastructure. Although both Rest (Representational State Transfer) and SOAP(Simple Object Access Protocol) share attributes in common with how they handle HTTP protocols, there are a number of key differences as discussed in this article.
