Around the advent of GraphQL, I found myself asking its proponents if HTTP/2 solves any of the same performance problems. Most of the answers were along the lines of, “it might, but that hasn’t been realized yet.” Well, Vulcain is here to realize it.

Over the years, several formats have been created to fix performance bottlenecks impacting web APIs: over fetching, under fetching, the n+1 problem…

Current solutions for these problems (GraphQL, JSON:API’s embedded resources and sparse fieldsets, …) are smart network hacks for HTTP/1. But these hacks come with (too) many drawbacks when it comes to HTTP cache, logs and even security.

Fortunately, thanks to the new features introduced in HTTP/2, it’s now possible to create true REST APIs fixing these problems with ease and class! Here comes Vulcain!

Go Time panelist Jon Calhoun ruminates on a conversation started on episode 94 of the show:

The goal of this article is it explore why exactly there isn’t a single app structure that is recommended to new Gophers, and the overall goal of this series is help newcomers to Go understand what choices are available to them so they can get started a little easier.

Johnny is joined by Marty Schoch, creator of the full-text search and indexing engine Bleve, to talk about the art and science of building capable search tools in Go. You get a mix of deep technical considerations as well as some of the challenges around running a popular open source project.

Manish Jain and Karl McGuire of Dgraph join Johnny and Jon to discuss caching in Go. What are caches, hit rates, admission policies, and why do they matter? How can you get started using a cache in your applications?

An extendable Go cache library that brings you a lot of features for caching data.

Mat is joined by Peter Bourgon, Kat Zień, and Ben Johnson to talk about application design in Go — principles, trade-offs, common mistakes, patterns, and the things you should consider when it comes to application design.

Muon is a lightweight alternative to Electron written in Golang in about ~300 LoC, using Ultralight instead of Chromium. Ultralight is a cross-platform WebKit rewrite using the GPU to target embeded desktop applications that resulted in a fast, lightweight, and low-memory HTML UI solution that blends the power of Chromium with the small footprint of Native UI.

Between this, NodeGui, and Catalina’s support for React Native, Electron is getting squeezed on all sides.

Mat, Filippo, Johan, and Roberto discuss security in Go. Does Go make it easy to secure your code? What common mistakes are Gophers making? What is fuzzing? How can attackers abuse your code if you use the default http mux?

I’ve been a big fan of Segment since way back before they became our sponsors. The adapter pattern for marketing/analytics tools is a great idea and they’ve executed on it very well. I’m also a big fan of open source alternatives to commercial products. 😀

If the “Why Rudder?” section of the README (privacy & security, processing flexibility, unlimited events) has you nodding in agreement, this is worth a deeper look.

intended for building event driven applications, enabling event sourcing, RPC over messages, sagas and basically whatever else comes to your mind. You can use conventional pub/sub implementations like Kafka or RabbitMQ, but also HTTP or MySQL binlog if that fits your use case.

Check out the announcement post for more of the background on Watermill.

Carmen and Jon talk with Rob Pike and Robert Griesemer (the creators of Go) about its origins, growth, influence, and future. This an epic episode that dives deep into the history and details of the how’s and why’s of Go, and the choices they’ve made along the way in creating this awesome programing language.

navi allows you to browse through cheatsheets (that you may write yourself or download from maintainers) and execute commands, prompting for argument values.

Johnny, Carmen, Jon, and returning guest Stevenson Jean-Pierre talk about hiring engineers with a focus on junior roles. Why do we keep running into these ridiculous job listings that nobody could ever live up to? What benefits do junior developers bring to the team? Why don’t teams put more focus on developing junior engineers? What can we do better?

JSON formatted files are readable to humans but the lack of comments decreases readability. With JSONC, you can use block (/* */) and single line (//) comments to describe the functionality. Microsoft VS Code also uses this format in their configuration files like settings.json, keybindings.json, launch.json, etc.

This is a Go-only implementation, but the concept is portable to any language (hint, hint).

Mat, Johnny, Jon, and special guest Ian Lance Taylor discuss generics in Go. What are generics and why are they useful? Why aren’t interfaces enough? How will the standard library change if generics are added to Go? How has the community contributed to generics? If generics are added, how will this negatively affect the language?

LIVE from LondonGophers as part of GopherCon UK! Mat Ryer, and Mark Bates were joined by Liz Rice, Kat Zień, Gautam Rege to talk about the magic in Go’s standard library. Huge thanks to the organizers of LondonGophers and GopherCon UK for making this possible.

Johnny, Mat, Jaana, and special guest Stevenson Jean-Pierre discuss serverless in a Go world. What is serverless, what use cases is serverless good for, what are the trade offs, and how do you program with Go differently in the context of serverless?

Diztl uses gRPC under the hood and is written in Go. See it in action in this demo video.

Arduino announced they now work with TinyGo. To celebrate, they did a Q&A with Ron Evans on the Arduino blog.

Why choose TinyGo over other languages? If software is eating the world, then Go is eating the world of software. The popularity of Go is still rapidly expanding, and TinyGo helps bring the new “enterprise standard” language down to the smallest of processors. Also as a compiled language, TinyGo can offer substantially better performance and size efficiency than that of interpreted languages like JavaScript and Python.

If you haven’t yet, listen to our recent conversation with Ron Evans at OSCON 2019 to hear more about how “Go is eating the world of software.”

There are other spider management systems out there, but most of them limit you to Python because Scrapyd. Crawlab has no such dependency, so you can use whichever language/framework you’d like.

(This looks like a pain to operate, but docker-compose helps quite a bit in that arena.)

Hot off the heels of GopherCon 2019 — Johnny Boursiquot, Jon Calhoun, and special guests Jamal Yusuf, and Yingrong Zhao recap the conference and the importance of representation in the Go community.

I linked to this repo awhile back, but it’s worth another mention as more & more people are wanting to learn Go. It also contains a nice write-up on why unit testing and TDD is important.

Jon, Mat, Johnny, and special guest Cory LaNou discuss the ins and outs of structuring Go programs. Why is app structure so important? Why is it hard to structure Go apps? What happens if we get it wrong? Why do we confuse folder structures with application design? How should a new Go app be structured?

It aims to be part of the developer’s toolkit for gaining insight and approaching complexity found in Kubernetes. Octant offers a combination of introspective tooling, cluster navigation, and object management along with a plugin system to further extend its capabilities.

Jon, Mark, Johnny, and special guest Jamal Yusuf discuss what to expect when attending a conference like GopherCon. What should you be doing before you attend GopherCon? What should you bring to the conference? What shouldn’t you bring? What are the training sessions about? What about the hacking sessions and talking with the Go team? What if you don’t know anyone?
