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.

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.

Its focus is on executing async long-running business logic. Business logic is modeled as workflows and activities. Workflows are the implementation of coordination logic. Its sole purpose is to orchestrate activity executions. Activities are the implementation of a particular task in the business logic. The workflow and activity implementation are hosted and executed in worker processes. These workers long-poll the Cadence server for tasks, execute the tasks by invoking either a workflow or activity implementation, and return the results of the task back to the Cadence server. Furthermore, the workers can be implemented as completely stateless services which in turn allows for unlimited horizontal scaling.

sshcode is a CLI to automatically install and run code-server over SSH. It uploads your extensions and settings automatically, so you can seamlessly use remote servers as VS Code hosts. If you have Chrome installed, it opens the browser in app mode. That means there’s no keybind conflicts, address bar, or indication that you’re coding within a browser. It feels just like native VS Code.

The purpose of this roadmap is to give you an idea about the landscape. The road map will guide you if you are confused about what to learn next, rather than encouraging you to pick what is hip and trendy. You should grow some understanding of why one tool would be better suited for some cases than the other and remember hip and trendy does not always mean best suited for the job

We’re talking with Syrus Akbary about WebAssembly and Wasmer — a standalone just in time WebAssembly runtime aiming to be fully compatible with Emscripten, Rust, and Go. We talked about taking WebAssembly beyond the browser, universal binaries, what’s an ABI?, running WebAssembly from any language, and what a world might look like with platform independent universal binaries powered by WebAssembly.

The core idea of this project is to do more with less. PipeHub being a programmable proxy allow users to extend and customize it as needed. Features found in other servers can be added with Go packages. Not ready for production, but interesting nonetheless. Not sure if PipeHub is something that might serve you well? Here’s some pretty good advice to help you decide: If your requirement is covered by built-in features present on other servers like Nginx and Caddy, you’re better of with then. PipeHub shines when you need to add logic that traverses the responsibility of multiple servers…

This is Dave Cheney’s working document for his Practical Go workshop. So much wisdom shared. My goal over the next two sessions is to give you my advice for best practices writing Go code. This is a workshop style presentation, I’m going to dispense with the usual slide deck and we’ll work directly from the document which you can take away with you today. There’s also this page of the same name on his site, but I’m not sure if they’re directly connected.

Todd Kulesza and Steve Francia shared the details of Go’s 2018 survey on the Go blog. This year we had 5,883 survey respondents from 103 different countries … For the first time, half of survey respondents are now using Go as part of their daily routine. The most common uses for Go remain API/RPC services and CLI tools. Automation tasks, while not as common as CLI tools and API services, are a fast-growing area for Go.

We’re talking with Greg Kurtzer, the founder of CentOS, Warewulf, and most recently Singularity — an open source container platform designed to be simple, fast, and secure. Singularity is optimized for enterprise and high-performance computing workloads. What’s interesting is how Singularity allows untrusted users to run untrusted containers in a trusted way. We cover the backstory, Singularity Pro and how they’re not holding the open source community version hostage, as well as how Singularity is being used to containerize and support workflows in artificial intelligence, machine learning, deep learning, and more.

inlets combines a reverse proxy and websocket tunnels to expose your internal and development endpoints to the public Internet via an exit-node. An exit-node may be a 5-10 USD VPS or any other computer with an IPv4 IP address. You may be wondering why this project needs to exist, since many like it have come before. The author addresses that right up front: Similar tools such as ngrok or Argo Tunnel from Cloudflare are closed-source, have limits built-in, can work out expensive and have limited support for arm/arm64. Ngrok is also often banned by corporate firewall policies meaning it can be unusable. Other open-source tunnel tools are designed to only set up a static tunnel. inlets aims to dynamically bind and discover your local services to DNS entries with automated TLS certificates to a public IP address over its websocket tunnel.

Have you ever seen someone write something to the effect of “I would use Go, but I need generics”? Perhaps we can infer from this that many of the people who are pining after generics in Go are not, in fact, Go users. The inertia of “what I’m used to” comes to a violent stop when they try to use Go. People affected by this frustration interpret it as a problem with Go, that Go is missing some crucial feature - such as generics. But this lack of features is itself a feature, not a bug.
