We’re joined by Ron Evans at OSCON on the expo hall floor talking about Go and how it’s eating the world of software. Specifically we’re talking about TinyGo and what they’re doing to bring the Go programming language to micro-controllers and modern web browsers. According to Ron Evans, “embedded systems and Go are the most exciting things happening right now.”

OctoSQL is a SQL query engine which allows you to write standard SQL queries on data stored in multiple SQL databases, NoSQL databases and files in various formats trying to push down as much of the work as possible to the source databases, not transferring unnecessary data. OctoSQL does that by creating an internal representation of your query and later translating parts of it into the query languages or APIs of the source databases. Whenever a datasource doesn’t support a given operation, OctoSQL will execute it in memory, so you don’t have to worry about the specifics of the underlying datasources. If you like writing SQL, you’ll probably like OctoSQL.

A proof-of-concept virtual Kubernetes control plane that lets you take one physical Kubernetes cluster and chop it up in to smaller virtual clusters. The benefits of doing this are: Better security/multitenancy Better separation of concerns between infra and custom controllers (operators) Ability to package complex k8s based applications

Mat Ryer, Mark Bates, Johnny Boursiquot, and Aaron Schlesinger discuss web development in Go. Go is great at writing server technology, but how good is it for web development? We’ll talk about HTTP, templating, the front-end, Wasm, and we even discuss Buffalo with its creator, Mark Bates.

Mat and Carmen along with guest panelists Dave Cheney, Peter Bourgon, and Marcel van Lohuizen discuss errors in Go, including the new try proposal. Many questions get answered…What do we think about how errors work in Go? How is it different from other languages/approaches? What do/don’t we like? What don’t we like? How do we handle errors these days? What’s going on with the try proposal?

This is a subjective, primarily developer-ergonomics-based comparison of the three languages from the perspective of a Python developer, but you can skip the prose and go to the code samples, the performance comparison if you want some hard numbers, the takeaway for the tl;dr, or the Python, Go, and Rust diffimg implementations. Not only is this a good way to compare programming languages, but it’s a good way to learn a new language if you’re already familiar with one of the others.

We’re talking about the tools we use every day help us to be productive! This show will be a great introduction for those new to Go tooling, with some discussion around what we think of them after using some of them for many years.

Memorising docker commands is hard. Memorising aliases is slightly less hard. Keeping track of your containers across multiple terminal windows is near impossible. What if you had all the information you needed in one terminal window with every common command living one keypress away (and the ability to add custom commands as well). Lazydocker’s goal is to make that dream a reality.

Panelists Mat Ryer, Johnny Boursiquot, Jon Calhoun, and guest panelist Egon Elbre discuss what they build, why, and how they do it. Everybody has their own unique process for getting things done, so today we’re going to learn about them. Too often processes get in the way and slow things down. How do we look for signs of those slow downs? How do we create a space where people are free to discuss their thoughts and struggles?

Panelists Mark Bates, Johnny Boursiquot, and Carmen Andoh discuss Go and open source — what is it, the value in contributing, what it means to be a maintainer, best practices, and the recent blog post from Chris Siebenmann titled “Go is Google’s language, not ours.”

Fellow Gophers and Go Time fans out there, I’d love to hear your thoughts on this post from Chris Siebenmann. Go has community contributions but it is not a community project. It is Google’s project. This is an unarguable thing, whether you consider it to be good or bad, and it has effects that we need to accept. For example, if you want some significant thing to be accepted into Go, working to build consensus in the community is far less important than persuading the Go core team. In general, it’s extremely clear that the community’s voice doesn’t matter very much for Go’s development, and those of us working with Go outside Google’s walls just have to live with that.

A clever hack that is now being investigated by Google’s internal forums. How it works: Google Docs take up 0 bytes of quota in your Google Drive Split up binary files into Google Docs, with base64 encoded text Encoded file is always larger than the original. Base64 encodes binary data to a ratio of about 4:3. A single doc can store ~1 million characters. This is around 710KB of base64 encoded data.

How do beginners learn Go? This episode is meant to engage both non-Go users that listen to sister podcasts here on Changelog, or any Go-curious programmers out there, as well as encourage those that have started to learn Go and want to level up beyond the basics. On this episode we’re aiming to answer questions about how to learn Go, identify resources that are available, and where you can go to continue your learning journey.

Clearly we’re a fan of Go — listen to Go Time — but, what is it going to take to make it succeed Java as the dominating enterprise programming language? This post from Kevin Goslar lays out the strengths of Go that make this a real possibility. Go — a programming language designed for large-scale software development — provides a robust development experience and avoids many issues that existing programming languages have. … Companies and open-source initiatives looking for a safe and forward-looking technology choice for creating large-scale cloud infrastructures in the coming decades are well advised to consider Go as their primary programming language. A large portion of modern cloud, networking, and DevOps software is written in Go, for example Docker, Kubernetes, Terraform, etcd, or ist.io.Many companies are using it for general-purpose development as well. The capabilities that Go enables have allowed these projects to attract a large number of users, while Go’s ease of use has enabled many contributions.

If you haven’t attended the workshop directly, the next best thing is to learn indirectly by reading the workshop’s docs. The goal for this workshop is to give you the tools you need to diagnose performance problems in your Go applications and fix them.

From writing and optimizing Go code to common gotchas with the Go standard library, Damian Gryski shared his thoughts on Go performance optimization and outlined best practices for writing high-performance Go code. Available in English, 中文, and Español. When and where to optimize — Every optimization has a cost. Generally this cost is expressed in terms of code complexity or cognitive load – optimized code is rarely simpler than the unoptimized version. But there’s another side that I’ll call the economics of optimization. As a programmer, your time is valuable. There’s the opportunity cost of what else you could be working on for your project, which bugs to fix, which features to add. Optimizing things is fun, but it’s not always the right task to choose. Performance is a feature, but so is shipping, and so is correctness.
