k8sgpt is a tool for scanning your Kubernetes clusters, diagnosing and triaging issues in simple english. It has SRE experience codified into it’s analyzers and helps to pull out the most relevant information to enrich it with AI.

A multi-tenant HTTP reverse tunnel solution through remote port forwarding from the SSH protocol.

This is intended for small teams that need to expose the local development environment to the public internet, and you need to bring your own domain name and SSO provider.

It gives stable subdomain for every user, and gated by your SSO through OIDC protocol.

Think this as a bare-bone alternative to the ngrok’s $65/user/month enterprise tier. Try to put this behind a production system will blow up your SLA.

For individuals and production systems, just buy ngrok, it is still my favorite.

Service Weaver is a programming framework for writing, deploying, and managing distributed applications in Go. With Service Weaver, you write your application like it is a traditional, single-process Go executable that runs on your local machine. Then, you deploy it to the Cloud, and the framework breaks it down into a set of connected microservices and integrates it with the cloud provider (e.g., monitoring, tracing, logging).

Ben Hoyt shares his experience switching two of his side projects from on an EC2 instance to Fly.io:

It took me about an hour to figure out the basics of Fly.io and move the simpler project, and a couple of evenings to move the more complex one. Fly.io handles the annoying reverse proxy and SSL stuff, deployment is as simple as fly deploy, and there’s a nice dashboard on Fly.io to show me what’s going on…

I’m only a few weeks into using Fly.io to host my side projects, but I’m very happy with their product so far. I was quite happy to delete the 500 lines of Ansible scripts, systemd unit files, and Caddy config files.

It also made me smile to finally stop the EC2 instance and bump my AWS bill down from $9 per month to about 10 cents per month (I still use S3 for user-uploaded images and for backups). I have nothing against EC2 and would use it again for certain things, but for small web applications, Fly.io seems like a great fit.

Filippo Valsorda:

Last May I left my job on the Go team at Google to experiment with more sustainable paths for open-source maintainers. I held on to my various maintainer hats (Go cryptography, transparency tooling, age, mkcert, yubikey-agent…), iterated on the model since September, and I’m happy to report that I am now a full-time independent open-source maintainer.

People like Filippo are still (unfortunately) the exception, not the rule. BUT! I’ll celebrate every time an open source maintainer makes it to the promised land, hopefully paving the way for others to follow after.

I’m sharing details about my progress to hopefully popularize the model, and eventually help other maintainers adopt it, although I’m not quite ready to recommend anyone else drop everything to try this just yet.

I love a good “I built a thing and here is how I built that thing” post, especially when it’s penned by someone like Chris who’s sure to keep you entertained along the way.

Wouldn’t it be neat to have aggregated data (for a website, daily email, push alert, etc) of kids events in our surrounding area so we know about them right away?

Distributed, offline-first bug tracker embedded in git, with bridges

I love the idea of having your bug repo right there inside your code repo. The terminal UI is a nice touch!

Robert Laszczak does a good job defending/explaining many gophers’ position on frameworks:

Go frameworks exist, but none provides a feature set like frameworks from other languages. This won’t change soon.

You may think that it’s because the Go ecosystem is younger. But there is a more important factor. Go is built around the Unix Philosophy…

Why another file manager? I wanted something simple and minimalistic. Something to help me with faster navigation in the filesystem; a cd and ls replacement. So I build “llama”. It allows for quick navigation with fuzzy searching. cd integration is quite simple. And you can open vim right from the llama. That’s it. As simple and dumb as a llama.

It stores your shell history in context (what directory you ran the command in, whether it succeeded or failed, how long it took, etc). This is all stored locally and end-to-end encrypted for syncing to to all your other computers. All of this is easily queryable via the hishtory CLI. This means from your laptop, you can easily find that complex bash pipeline you wrote on your server, and see the context in which you ran it.

Russ Cox, for the Go team:

Today we celebrate the thirteenth birthday of the Go open source release. The Gopher is a teenager!

It’s been an eventful year for Go. The most significant event was the release of Go 1.18 in March, which brought many improvements but most notably Go workspaces, fuzzing, and generics.

He goes on to describe many of the other notable features and events of the past year and closes with a glance into Go’s future:

In Go’s 14th year, we’ll keep working to make Go the best environment for software engineering at scale. We plan to focus particularly on supply chain security, improved compatibility, and structured logging, all of which have been linked already in this post. And there will be plenty of other improvements as well, including profile-guided optimization.

Katana can run in standard mode, which is like curl/wget, or it can run in headless mode, which is like a real web browser with JavaScript parsing and all that jazz. And since it’s written in Go, you get that silky universal binary experience. Just drop it in your $PATH and you’re off to the races!

This is for people who need to administer a handful of machines, all fairly different from each other and all Very Important. Those systems are not Cattle! They’re actually a bit more than Pets. They’re almost Family. For example: a laptop, workstation, and that personal tiny server in Sweden. They are all named after something dear.

Liz Rice and I spoke about pets & cattle recently on The Changelog. I asked her, “from your perspective, are the people still doing it the old-school pets way?”

This tool is a great example of Pets-style administration being alive and well.

An open-source knowledge based community software. You can use it to quickly build your Q&A community for product technical support, customer support, user communication, and more.

Install with Docker, a Go binary, or from source.

This is a journey of how I, a developer unfamiliar with C, went down the rabbit hole of navigating the SQLite source and changed it to offer a capability that wasn’t available.

Zach Musgrave from Dolt reviews several case studies of performance problems they ran into while benchmarking Dolt DB to get row access to be as fast as MySQL.

Oh, and he also shares how to fix each problem, which is nice. 😉

Podinfo is a tiny web application made with Go that showcases best practices of running microservices in Kubernetes.

This is used by CNCF projects like Flux and Flagger for end-to-end testing as well as workshops.

Michael Knyszek:

Since our last blog post about the Go GC in 2018 the Go GC, and the Go runtime more broadly, has been steadily improving. We’ve tackled some large projects, motivated by real-world Go programs and real challenges facing Go users. Let’s catch you up on the highlights!

Lots of invisible changes/improvements, but Michael focuses in on a new knob that he’s encouraging gophers to play with: the soft memory limit

We recently logged jqq (an interactive wrapper around jq), but Ruby means installing it can be a burden. jqp wraps gojq, so it compiles to a universal binary and the UI is pretty compelling as well.

The title of this post is “Why I Love Go”, I saw it shared by Rob Pike (one of the founding team for Go). In the post David Yach talks about how productive interns can be with Go, writing substantial prototypes in a short period of time. That’s one of the reasons I like to use it for OSS container/networking projects and developer tools too.

This is cool because portability. But also because you can embed it as a library in your Go projects. It’s not identical to jq in practice, though. Here’s a long list of differences between the two.

Julie Qiu, announcing Go’s new support for vulnerability management:

Go provides tooling to analyze your codebase and surface known vulnerabilities. This tooling is backed by the Go vulnerability database, which is curated by the Go security team. Go’s tooling reduces noise in your results by only surfacing vulnerabilities in functions that your code is actually calling.

There’s a new govulncheck command you can/should install and run against your project. It surfaces only the vulnerabilities that actually affect you, which is awesome.

Govulncheck is a standalone tool to allow frequent updates and rapid iteration while we gather feedback from users. In the long term, we plan to integrate the govulncheck tool into the main Go distribution.

Every so often, engineers need to pick up a new language. After ~6 years of professional development using Java, with a bit of Ruby sprinkled in, coming to Deliveroo meant that I’d be starting to work on some Go codebases.

So when it came to accepting the offer, I ended up thinking about getting started with learning Go, so I could hit the ground running. In this post I share different ways to get practical experience of the language, as well as thoughts on what Go is like to a newbie

You can think of this like fetch() or curl but entirely in SQL:

select request_url, response_status, response_headers 
  from http_get('http://httpbin.org/get');

The cool thing is you can save everything from the request: status code, headers, the body (of course), timestamps, and more. Great for archiving!

-- initialize a table
create table snapshots as
  select * from http_get('https://changelog.com');

-- To add more rows later on
insert into snapshots
  select * from http_get('https://changelog.com');
