Golang News, Tutorials, Go Libraries and Golang Jobs
A new Golang hash table based on SwissTable that is faster and uses less memory than Golang’s built-in map. We’ll cover the motivation, design and implementation of this new package and give you some reasons to try it. This blog is part of our deep-dive series on the Go programming language. Past iterations include posts about concurrency, “inheritance”, and managing […]
Flipt is an open-source, self-hosted feature flag application that allows you to run experiments across services in your environment. Flipt can be deployed within your existing infrastructure so that you don’t have to worry about your information being sent to a third party or the latency required to communicate across the internet. Usecases Flipt supports use cases […]
The other day I was pondering the prevalence of single-method interfaces (SMI) in Go, and what makes them so practical and helpful. SMIs have proven to be a very successful software modeling tool for Go programmers, and you find them all over Go code-bases. I tried to think about the fundamentals, which brought me to […]
Valgo is a type-safe, expressive, and extensible validator library for Golang. Supports localization and is built with generics. Getting started Install in your project: Import in your code: Note: You can use any other aliases instead of v or just reference the package valgo directly. Using Valgo Validation session The Validation session in Valgo is the main structure for validating one or […]
Kopia is a fast and secure open-source backup/restore tool that allows you to create encrypted snapshots of your data and save the snapshots to remote or cloud storage of your choice, to network-attached storage or server, or locally on your machine. Kopia does not ‘image’ your whole machine. Rather, Kopia allows you to backup/restore any and all files/directories that you deem […]
A migration guide from github.com/hashicorp/go-multierror to the std library errors package. In go1.20 support for “multierrors” was added. Why migrate? # Migrating from community go modules to standard library implementations is almost always a no-brainer if it provides like for like functionality. Packages in the core go standard library such as errors are covered by the go1.0 backwards compatibility guarantee [0].Because of […]
This project brings a backend server with its frontend for managing authorizations. You can use both Role-Based Acccess Control (RBAC) and Attribute-Based Access Control (ABAC). Why use it? A centralized backend for all your applications authorizations Supports Role-Based Access Control (RBAC) Supports Attribute-Based Access Control (ABAC) Multiple language SDKs available Reliable: Authz uses Authz itself […]

See CONTRIBUTING for details on submitting patches and the contribution workflow. CI Pull requests should be appropriately labeled, and linked to any relevant bug or feature tracking issues. All […]
Go is designed to make concurrency easier than it is in other languages, but at Sourcegraph, I still found myself running into the same problems repeatedly when writing concurrent code. In particular, it is difficult to write concurrent code that operates reasonably in the face of panics. We don’t want the entire process to crash […]
There are a lot of materials about how to write services, where at first you need to choose some framework to use, then comes wiring of handlers, configs, logs, storage, etc, not to mention deploying that service somewhere. We’ve been writing services for quite some time and more often than not you’d just want to […]
