I'm beginning to research the right way to better integrate how we achieve SCA / shift-left / SecureDevOps / secure software supply chain. If you use or have evaluated WhiteSource, Snyk, Sonatype Nexus, SonarQube or similar, I would very much appreciate your perspective on strengths and weaknesses and how you selected your ultimate solution. I want to integrate with GitLab CI.

I'd recommend Snyk since it provides an IDE extension for Developers, SAST, auto PR security fixes, container, IaC and includes open source scanning as well. I like their scoring method as well for better prioritization. I was able to remove most of the containers and cli tools I had in my pipelines since Snyk covers secrets, vulns, security and some code cleaning. SAST has false positives but the scoring helps. Also had to spend time putting some training docs but their engineers helped out with content.

Decisions about RuboCop and Snyk
Weverton Timoteo

To communicate isn’t just getting rid of syntax errors and making code work. The code should communicate ideas to people through a programming language that computers can also understand.

You should adopt semantic variables, classes, modules, and methods names. For instance, in Ruby, we avoid using particular prefixes such as is_paid, get_name and set_name. In their places, we use directly paid?, name, and name=.

My advice is to use idiomatic and features that the programming language you use offers to you whenever possible, and figure out ways to better pass the message.

Why wouldn’t we be worried about semantics, typos, and styles? We should care for the quality of our code, and the many concepts that define it. You can start by using a linter to collect some issues from your codebase automatically.
