Learning Kubernetes can seem overwhelming. It’s a complex container orchestration system, that has a steep learning curve. But with the right roadmap and understanding of the foundational concepts, it’s something that any developer or ops person can learn.

In this Kubernetes learning roadmap, I have added prerequisites and complete Kubernetes learning path covering basic to advanced Kubernetes concepts.

This Dockerfile automates the setup of OSX-KVM. All your host system needs is hardware virtualization enabled in BIOS and QEMU installed.

This animated “children’s” book is spectacularly good. It centers around a growing community of otters, their struggles to communicate efficiently, and one little otter named Nixie’s great idea that changed the forest forever.

Put, put, put your events
gently in the stream
There they’ll float, down and down
In the river’s gleam

Fresh on the heals of our TS Party comes this curated list of tools for getting the most out of static code analysis. This list is gloriously polyglot, so there’s probably something in there for everyone.

Not in to static analysis (or just a huge fan of lists)? Check out the sister project, Awesome Dynamic Analysis.

Biscuit is a monolithic, POSIX-subset operating system kernel in Go for x86-64 CPUs. It was written to study the performance trade-offs of using a high-level language with garbage collection to implement a kernel with a common style of architecture.

With ~38k commits and 8+ years of dev, this has been a massive effort. Find the research paper right here.

“GUIs are bloatware” — Terminal rules…a guide to the terminal…

In this post, I’ll walk you through everything you need to start making your terminal a complete development environment: how to edit text efficiently, configure its appearance, run and combine a myriad of programs, and dynamically create, resize and close tabs and windows.

Mint is super cool, but handing over your precious financial information to a 3rd-party is always a bit nerve-racking. Evan You’s new Node app builds a bridge between Plaid (for bank access) and Google Sheets (for data storage) so you can roll your own system.

Now you only have to trust your precious financial information to two 3rd-parties 😉. But! This is open source so at least you don’t have to trust the application code.

Programming around time is the bane of pretty much every programmer’s existence. UTC works most of the time, but still has its flaws.

Zach Holman writes on his blog:

Programming time, dates, timezones, recurring events, leap seconds… everything is pretty terrible. The common refrain in the industry is Just use UTC! Just use UTC! And that’s correct…sort of. But if you’re stuck building software that deals with time, there’s so much more to consider. It’s time…to talk about time.

Zach includes a lot of time-related puns and whole lot of wisdom about programming time.

As we gear up for the launch of Practical AI and more AI/ML/DS related news coverage, I wanted to bring to your attention to this 6-month apprenticeship (compensated) in AI research at OpenAI.

We’re now accepting applications for the next cohort of OpenAI Fellows, a program which offers a compensated 6-month apprenticeship in AI research at OpenAI. We designed this program for people who want to be an AI researcher, but do not have a formal background in the field. Applications for Fellows starting in September are open now and will close on July 8th at 12AM PST.

Apply here.

Expose is a beautiful, open source, tunnel application that allows you to share your local websites with others via the internet.

Since you can host the server yourself, you have full control over the domains that your shared sites will be available at. You can extend expose with additional features and middleware classes on the server and client side, to make it suit your specific needs.

Alan Shreve closed ngrok’s source code years ago, and every now-and-again an open source alternative pops on the scene. Add Expose to the list. It’s written in PHP and has a nice shine on it. But which of these SSH tunneling tools is best in class?

A fun little side project by Mislav Cimperšak where you plug in a few values and it generates a shareable replica of XKCD’s famous Compiling comic. Here it is in action with a piece of modern art I call, “Low Hanging Fruit”. 😁

You’ve probably seen many of these commands hit Changelog News over the years, but now you can see them all again in one hand-curated place. Who knows, maybe one or two will be new to you. I hadn’t heard of curlie previously, which looks like a nice merging of cur and httpie.

Highly customizable, easy-to-use, and minimal terminal styled website template.

Building a simple website with LiveTerm only takes minutes, and you only need to work with one file: config.json. After you cloned this repository, simply run yarn install && yarn dev and start editing config.json to build your website!

I’ve had never really come into contact with hardware programming, working mostly in python or C#, until a friend of mine asked me for some help with programming a simple controller for RGB strips using Arduino Nanos.

We’d, of course, fail spectacularly.

Not only did our hardware not work quite like intended and a few Nanos died in the process(but that’s a story for another time), but I actually learned a lot from this and similar projects.

And I want to tell you some of my mistakes, what I learned by making them and how to prevent them.

I love this with my whole heart. 🤤

Maybe you’re thinking this is some kind of emulator that has been compiled to WebAssembly or a Docker thing somehow running in the browser. Nope! It’s a straight-up React-based web application that recreates the classic XP desktop. Most of the apps don’t actually exist, but have no fear: Minesweeper is here 🙌

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).

Eileen Uchitelle:

In total the project took a year and a half to upgrade from Rails 3.2 to Rails 5.2. Along the way we took time to clean up technical debt and improve the overall codebase while doing the upgrade. Below we’ll talk about how we upgraded Rails, lessons we learned and whether we’d do it again.

Congrats to Eileen and the team on this massive effort! Click through to read how they did it and the lessons the learned along the way.

If you need a JS runtime that supports TypeScript out of the box and has security as a top-most priority, star this repo and come back when it’s no longer “Segfaulty”.

Feature bullets! 👇

• No package.json, no npm. Not backwards compatible with Node
• Single executable
• Defaults to read-only file system access
• Always dies on uncaught errors
• Supports top-level await

EDIT: it’s worth noting that this project is by Ryan Dahl, inventor of Node.js.

This list is a lot longer than I expected! Alongside each app is an icon indicating whether it’s written in Swift or Objective-C, which is nice for those of us looking for reading material. 💪
