Lambdas are a powerful feature of the Ruby language. They allow you to wrap logic and data into a portable package. In this post, we’ll cover how and when to use lambdas. You'll also learn about the difference between lambdas and Procs, and the performance profile of lambda functions. The code examples have been tested with 2.6 and 2.7 and should work with most modern Rubys.

Nowadays, the term ‘remote debugging’ instills fear into even the bravest of dev hearts. Palms sweaty, knees weak, and arms ready (to code) they dive into what they’re sure will end in much pain and possibly a few broken pieces of code. This scenario and these feelings are common to devs everywhere, where many opt to take the trusted path of debugging on their *own* machines.

We've all been there. You're clicking around your Rails application, and it just isn't as snappy as it used to be. You start searching for a quick-fix and find a lot of talk about caching. Take your existing app, add some caching, and voila, a performance boost with minimal code changes. However, it's not this simple. Like most quick fixes, caching can have long-term costs.

If there’s one thing SRE professionals and Development engineers lack, it’s time. After all, engineers need to oversee a variety of processes—like ensuring operational stability, conducting integration testing, and maintaining cybersecurity—to make sure their apps are working optimally. The list goes on and on. With heavy workloads and tight deadlines, there’s little time to waste on software issues stemming from internal collaboration issues.

Working with Rookout customers, I have noticed a significant pattern in how they describe engineering routines in the days before our software became a part of their daily workflow. It shows up in various engineering tasks such as developing new features, reproducing and fixing bugs, or even just documenting the existing system and how to best utilize it. It is also consistent across industries and tech stack.

Laravel development services have been growing in popularity, with the Laravel framework often being compared to CakePHP. This article will show how to choose the best framework to meet specific business or solution requirements in the most effective way. Laravel and CakePHP are both very popular PHP frameworks. PHP is often used for creating dynamic websites or building high-end apps. PHP frameworks make it possible to create affordable websites with impressive UI/UX.

It is widespread to have parent-child associations in Rails applications. On the parent side is a :has_many association, and on the child side is a :belongs_to association. Examples include an article with comments, or an author with books--the former is the parent, and the latter is the child. It is often useful to display a count of the children alongside information about the parent, without necessarily loading all the child records.

We are excited to announce NSolid 3.11.1, which introduces Role Based Access Control along with support for Node.js Erbium v12.16.2 and Dubnium v10.20.1. If you are an Enterprise or Advanced Tier User, you can now use NodeSource’s central control nexus, accounts.nodesource.com to give and revoke Role Based Access Control permissions for the NSolid Console and accounts.nodesource.com.
