This project is a formalized list of checks that can be run against an open source codebase and a Go-based tool to run those checks and provide a report on the project’s health. Here are a few of the checks it runs, to get an idea of what it’s all about:

• Does the project use fuzzing tools, e.g. OSS-Fuzz?
• Does the project cryptographically sign releases?
• Does the project contain a security policy?

Learning Go with code pop quizzes is a fun way to zoom in on different language features. People are looking forward to pop quizzes on Twitter and in conferences, and they also learn from that. Let’s chat about pop quizzes!

We discuss how Test Driven Development (TDD) can help you write better code, and build better software. Packed with tips and tricks, gotchas and best practices, the panel explore the subject and share their real-world experiences.

The general idea is to leverage cache-friendly ways of organizing data in structures of arrays (SoA) otherwise known “columnar” storage in database design. This, in turn allows us to iterate and filter over columns very efficiently. On top of that, this package also adds bitmap indexing to the columnar storage, allowing to build filter queries using binary and, and not, or and xor (see kelindar/bitmap with SIMD support).

On this episode we’re talking with our good friend Mat Ryer whom you may know from the Go Time podcast. Mat created an awesome open source tool for putting just about anything in your Mac’s toolbar. It was originally written in Objective-C, but it just got a big rewrite in Go and abig rename from BitBar to xbar.

If you don’t use a Mac don’t hit skip on this episode quite yet! There are lessons to be learned for anyone interested in hacking on tools to make your life better. Plus, with this rewrite Mat has positioned xbar to go cross-platform, which we talk about as well.

Porter lets you package your application artifacts, client tools, configuration and deployment logic together as a versioned bundle that you can distribute, and then install with a single command. Written entirely in Go, we speak to one of the creators about running an open source project, the importance of documentation, and more.

This episode was recorded live from GopherCon Europe 2021!

Natalie & Mat host three amazing devs who gave talks that showcase using Go in unusual ways: Dr. Joakim Kennedy is tracking Go in malware, Mathilde Raynal is building quantum-resistant cryptography algorithms, and Preslav Rachev is creating digital art.

We hear from our speakers how they got into Go, how they made the choice to use Go for their unusual use case, and how it compares to other languages for their specific needs.

We also chat about conference talks, submissions and public speaking - how to start, good practices, and tips they collected along the way.

We first talked fuzzing with Katie Hockman back in August of 2020. Fast-forward 10 months and native fuzzing in Go is ready for beta testing! Here’s Katie explaining fuzzing, for the uninitiated:

Fuzzing is a type of automated testing which continuously manipulates inputs to a program to find issues such as panics or bugs. These semi-random data mutations can discover new code coverage that existing unit tests may miss, and uncover edge case bugs which would otherwise go unnoticed. Since fuzzing can reach these edge cases, fuzz testing is particularly valuable for finding security exploits and vulnerabilities.

It looks like the feature won’t be landing in Go 1.17, but they’re planning on it sometime after that. Either way, you can use fuzzing today on its development branch.

In the past decade a variety of games have emerged where players need to create an AI to play the game rather than play the game directly. In this episode we speak with the creator of one of those games - Battlesnake. Brad Van Vugt joins us to talk about building a game engine using Go, making programming games easier for beginners to get started with, the long term vision for games like Battlesnake, and more.

In this episode, we will talk about building for Blockchain in Go. We are joined by two of the co-founders of Prysmatic Labs (a company behind the upgrades to the Ethereum network). Raul Jordan and Preston Van Loon tell Angelica how they started the company, as well as what it’s like to build technical infrastructure for the Ethereum blockchain using Go.

Porter brings the Heroku experience to your own AWS/GCP account, while upgrading your infrastructure to Kubernetes. Get started on Porter without the overhead of DevOps and customize your infrastructure later when you need to.

For more on Porter, tune in to Go Time live on June 1st! Mat Ryer will be asking Carolyn Van Slyck all about it. If live isn’t an option… subscribe to Go Time, why don’t ya?

Namespace conflict! I mistook this Porter for that Porter which Carolyn Van Slyck works on. That Porter will be the subject of the June 1st Go Time, not this Porter. If you want us to do a show on this Porter, let us know. 😎

Tools and frameworks that aim to boost developer productivity are always worth a closer look, but we don’t often consider the trade-offs for whichever we settle on. In this episode, we discuss the questions one should be asking when evaluating developer productivity tools and frameworks in the Go ecosystem in particular.

Joining us to discuss is André Eriksson, the creator of Encore, a backend framework that aims to make development and deployment as productive as it can be.

Lima launches Linux VMs on your Intel or ARM-based Mac with automatic file sharing, port forwarding, and containerd. That means you can easily do cool stuff like:

$ echo "files under /Users on macOS filesystem are readable from Linux" > some-file

$ lima cat some-file
files under /Users on macOS filesystem are readable from Linux

$ lima sh -c 'echo "/tmp/lima is writable from both macOS and Linux" > /tmp/lima/another-file'

$ cat /tmp/lima/another-file
/tmp/lima is writable from both macOS and Linux"

Patrick DeVivo:

This is a project in Go that compiles to a SQLite runtime loadable extension, which brings Redis commands into a SQL context. This allows you to write SQL queries against data in a Redis instance, using Redis commands like LRANGE as SQL functions.

Experimental for now. But why? Patrick says:

In general, Redis is fairly accessible from many programming languages, and any query using reqlite could probably be implemented in a language of your choice using a Redis client. However, sometimes declarative SQL can be a better choice to express what you’re looking for, and that’s where this project may be most useful.

Syncthing synchronizes files between two or more computers. Its goals are to be:

1. Safe From Data Loss
2. Secure Against Attackers
3. Easy to Use
4. Automatic
5. Universally Available
6. For Individuals
7. Everything Else (!)

There’s a Goals document where these ideas are explained and expanded upon, which is neat.

In this episode we talk with Daniel and Steve about their experience with event-driven systems and shed some light on what they are and who they might be for. We explore topics like the complexity of setting up an event-driven system, the need to embrace eventual consistency, useful tools for building event-driven systems, and more.

Programmers are taught very early on about the importance of organizing their code. Whether it is naming variables and functions, or naming and organizing files, this is a topic covered early in nearly every programming course.

All of this begs the question: why is it so damn hard to figure out how to structure Go code?

Perspectives from both the workshop leaders perspective, as well as the workshop participants. What are some top tips, things to watch out for, and ways to innovate and keep your participants engaged, especially in the remote world we are now living in.

Startups are all about iterating quickly, building MVPs, and finding that elusive product market fit, so how does Go fit into that picture? Is Go a good choice for startups, or is it exclusively for the larger corporations? In this episode Jon is joined by four startup founders to learn about their experience building a startup with Go.

The internet wouldn’t exist as we know it if it weren’t for TCP and UDP, yet many developers don’t quite understand the technology powering the web. In this episode we talk with Adam Woodbeck, author of Network Programming with Go, to learn about TCP and UDP; what they are, how they work, and how one can experiment with tools like Wireshark and Go to learn more.

Encore uses static analysis and code generation to reduce the boilerplate you have to write, resulting in an extremely productive developer experience.

The list of superpowers is impressive, to say the least. I know gophers tend to be skittish when they’re approached by a framework, though, so I’d love to hear more about this project on Go Time…

The Call for Proposals for GopherCon 2021 is open from Monday, April 5th to Sunday, April 25th. Kris Brandow, an experienced GopherCon speaker, has published a series of guides to assist Gophers as they craft their proposals and think about submitting.

In this episode Kris reads through his guide, discussing the four parts with a GopherCon newbie, Angelica Hill, who spoke for the first time at GopherCon last year, and is a first time CFP reviewer this year.

Testing can be hard, how to test, where to test, what is a good test? All questions that can be deceptively difficult to answer. In this episode we talk about the trials and tribulations of testing and why it can be argued to be especially difficult in Go.

Lip Gloss takes an expressive, declarative approach to terminal rendering. Users familiar with CSS will feel at home with Lip Gloss.

I love how much love is going in to terminal UIs these days 👏

This week Alexander Neumann takes Jerod on a tour of Restic, the world-class backup solution that’s fast, secure, and cross-platform. We discuss why he created Restic in the first place, how (and why you should) you use it, some of its more interesting technical bits, lessons learned over the years building and maintaining a community, and more of course.
