Anywherelan (awl for brevity) is a mesh VPN project, similar to tinc, direct wireguard or tailscale. Awl makes it easy to connect to any of your devices (at the IP protocol level) wherever they are.

A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.

A shell parser, formatter, and interpreter with bash support; includes shfmt

Go 1.21 brings many exciting things, from profile-guided optimization to standard library packages for structured logging, slices and maps operations (see the release notes for details). In this post, I’d like to skip all that and focus on the features that caught my eye: the new builtins.

In case you’re wondering, builtins are functions that do not require importing a package, like len or make. Go 1.21 brings three more of them: min, max and clear. Let’s take a look.

a Go Notebook Kernel for Jupyter

Create a new production-ready project with backend (Golang), frontend (JavaScript, TypeScript) and deploy automation (Ansible, Docker) by running only one CLI command.

Focus on writing your code and thinking of the business-logic! The CLI will take care of the rest.

Dkron is a distributed cron service, easy to setup and fault tolerant with focus in:

- Easy: Easy to use with a great UI
- Reliable: Completely fault tolerant
- Highly scalable: Able to handle high volumes of scheduled jobs and thousands of nodes

Dkron is written in Go and leverage the power of the Raft protocol and Serf for providing fault tolerance, reliability and scalability while keeping simple and easily installable.

What does this library do?

Its task is simple: It tells you which language some text is written in. This is very useful as a preprocessing step for linguistic data in natural language processing applications such as text classification and spell checking. Other use cases, for instance, might include routing e-mails to the right geographically located customer service department, based on the e-mails' languages.

At Grab, we rely heavily on a large Go monorepo for backend development, which offers benefits like code reusability and discoverability. However, as we continue to grow, managing a large monorepo brings about its own set of unique challenges.

As an example, using Go commands such as go get and go list can be incredibly slow when fetching Go modules residing in a large multi-module repository. This sluggishness takes a toll on developer productivity, burdens our Continuous Integration (CI) systems, and strains our Version Control System host (VCS), GitLab.

In this blog post, we look at how Athens, a Go module proxy, helps to improve the overall developer experience of engineers working with a large Go monorepo at Grab.

Fixed-window rate limiting: This is a straightforward algorithm that counts the number of requests received within a fixed time window, such as one minute. Once the maximum number of requests is reached, additional requests are rejected until the next window begins.

Upcoming version of the Go programming language, which is expected to be released in the fall of 2023, will introduce a new package named slog. It provides a clean and consistent API for structured logging. Let’s take a closer look on how to use this new library.

I’d like to preface this article by saying that it is not an authoritative guide, rather it is just me documenting my experience figuring various things out, in the hope that it’ll be useful or interesting to someone else. I assume some knowledge of Nix and containerization throughout this article.

Mailpit is a multi-platform email testing tool & API for developers.

It acts as both an SMTP server, and provides a web interface to view all captured emails. It also contains an API for automated integration testing.

Mailpit is inspired by MailHog, but modern and much, much faster.

Why SQLite and Go in the cloud are a great match, getting started, best practices, and more.

Timecraft is a software runtime that executes WebAssembly modules with sandboxing, task orchestration, and time travel capabilities.

The development of distributed systems comes with many challenges, and satisfying the instrumentation, scale, or security requirements adds to the difficulty. By combining a sandbox, a task orchestrator, and a time machine in a software runtime, Timecraft intends to bring the tools and structure to help developers on their journey to construct, test, and operate such systems.

go get like, simple CLI that allows automated versioning of Go package level binaries (e.g required as dev tools by your project!) built on top of Go Modules, allowing reproducible dev environments.
