Rails Mini Profiler

Rails Mini Profiler is an easy-to-use performance profiler for your Rails applications. It is heavily inspired by Rack Mini Profiler GitHub - MiniProfiler/rack-mini-profiler: Profiler for your development and production Ruby rack apps. - https://github.com/MiniProfiler/rack-mini-profiler and other APM tools.

Rails Mini Profiler improves upon rack-mini-profiler in the latter regard. It is a developer tool, rather than a monitoring tool, and sets a big focus on developer experience. Simply put, it aims to be the best tool available to help you figure out why specific requests are slow.

As such, compared to rack-mini-profiler, it does not support non-Rails apps (e.g. Sinatra) or production sampling, but provides a much better user experience and better supports API-only applications.

Type Scopes

Type scopes creates useful semantic scopes based on the type of the columns of your models. It handles dates, times, strings, numerics and booleans.

Spring Boot, by default, serves content on the root context path (“/”). we’ll cover the different ways of configuring it.

SelfSigned

The SelfSigned issuer doesn’t represent a certificate authority as such, but instead denotes that certificates will “sign themselves” using a given private key. In other words, the private key of the certificate will be used to sign the certificate itself.

BRAC Authorization examples

Role-based access control (RBAC) is a method of regulating access to computer or network resources based on the roles of individual users within your organization.

Compiler Explorer

Compiler Explorer is an interactive compiler exploration website. Edit C, C++, Rust, Go, D, Haskell, Swift, Pascal, ispc or other language code, and see how that code looks after being compiled in real time. Multiple compilers are supported, many different tools and visualisations are available, and the UI layout is configurable (thanks to GoldenLayout).

GitLab Runner

GitLab Runner is an application that works with GitLab CI/CD to run jobs in a pipeline.

This article is about how to use Pulumi, kubernetes (K8S) provider, Helm Chart and TypeScript SDK to deploy GitLab Runner within Kubernetes (K8S).

Harbor

Harbor is an open source registry that secures artifacts with policies and role-based access control, ensures images are scanned and free from vulnerabilities, and signs images as trusted. Harbor, a CNCF Graduated project, delivers compliance, performance, and interoperability to help you consistently and securely manage artifacts across cloud native compute platforms like Kubernetes and Docker.

Nokogiri

Nokogiri (鋸) makes it easy and painless to work with XML and HTML from Ruby. It provides a sensible, easy-to-understand API for reading, writing, modifying, and querying documents. It is fast and standards-compliant by relying on native parsers like libxml2 © and xerces (Java).

ActiveSupport::Deprecation

When upgrading a Rails application to a newer version of the framework, you’ll often see deprecation warnings pop up in your application logs and test suite output. Deprecation warnings give you time to fix an issue before it becomes an outright error. Good deprecation warnings also give you a hint on where and how to address them.

Rails makes it pretty simple to add good deprecation warnings to your actual application code, too. Let’s first look at how to do this, then talk for a moment about when it might be a good idea.
