If you missed Go Remote Fest over the weekend then you missed this talk (slides only for now) from Daniel Martí on what’s coming in the next release of Go (Go 1.15) scheduled for August of this year.

What are you most excited about for this upcoming release of Go?

I was recently involved in an interesting project. Deploying a full production and development environment on a very budget-constrained Kubernetes cluster, managed through GKE. A big departure from my usual, where I have nearly unlimited budget for my cluster. The issues I ran into, and the solutions for them, were actually the inspiration to start this blog, just so I could write this post.

This is a great reason to start a new blog 👏

This is an interesting take on email that I haven’t seen before. Process your email like you process your user stories.

Delta provides language syntax-highlighting, within-line insertion/deletion detection, and restructured diff output for git on the command line. All the syntax-highlighting color themes that are available with bat are available with delta. Here’s what git show looks like when git is configured to use delta as its pager:

I’ve been using GitHub since the service’s inception and I still learned a thing from this excellent list of 10 tips & tricks from GitHubber Lee Reily. The details trick alone is worth the price of admission.

From principles like “always be aware of what’s going on in your team and product” to hiring advice like “what to look for in senior engineers”, this repo is brimming with knowledge anyone in (or considering) management should be aware of.

This post is part of a sample chapter from Essential Tools and Practices for the Aspiring Software Developer — a self-published in-progress book by Balthazar Rouberol and Etienne Brodu.

I estimate that I spend around 50% of my day working in my text editor and my terminal. Any way I can get more productive in these environments has a direct and measurable impact on my daily productivity as a whole.

If you spend a good chunk of your day repeatedly hitting the left and right arrow keys to navigate in long commands or correct typos, or hitting the up or down arrow keys to navigate your command history, this chapter should help you get more done quicker. We will cover some shell features you can leverage to make your shell do more of the work for you.

On a personal level, I probably use some of these up to 30 times a day, sometimes even without thinking about it, and it gives me a real sense of ownership of my tool.

We all know our users pay a cost when we push our JS framework in to their browser. Now, thanks to Tim Kadlec doing the yeoman’s work of crunching the numbers, we can approximate just how much that cost really is.

There is no faster (pun intended) way to slow down a site than to use a bunch of JavaScript. The thing about JavaScript is you end up paying a performance tax no less than four times:

1. The cost of downloading the file on the network
2. The cost of parsing and compiling the uncompressed file once downloaded
3. The cost of executing the JavaScript
4. The memory cost

Thanks to HTTP Archive, we can figure that out.

I’m pretty happy with how sites using jQuery size up. Granted, it’s not really a UI framework like the others are, but you have to imagine that many of those sites also use jQuery UI and their overall cost still compares well to the more modern solutions.

This is a little outside our normal beat, but I thought you’d appreciate knowing about these high res backgrounds before Monday’s standup. 🤓

Everyone knows that all code has bugs. Code is written under constraints. Deadlines. Goals other than quality. Imperfect knowledge of the future. Even your own skill as an engineer is a constraint. If we all tried to write perfect, bugless code, we’d never accomplish anything. So how does it make sense to apologize for bugs?

In this post Arthur covers the core concepts, the question “Should you use GitHub Actions?”, and a step-by-step tutorial to build a functional CI/CD pipeline using GitHub Actions.

If you are already using GitHub to host your project’s source code, getting started with GitHub Actions is effortless. The fact that it integrates fully with the entire GitHub ecosystem means your team can double down on using the platform as a significant part of your software development process.

Overall, my opinion is that GitHub Actions is worth a try. Whether this is the automation system best suited for your team depends on your specific needs.

Addy Osmani has created an excellent resource for all developers interested in optimizing their web performance (which should be pretty much all of us).

You’ve probably heard of Puppeteer, which lets you control Chromium headlessly over the DevTools protocol. This repo shows you how to use Puppeteer to automate performance measurement, such as getting a performance trace for a page load:

const puppeteer = require('puppeteer');
(async () => {
  const browser = await puppeteer.launch();
  const page = await browser.newPage();
  // Drag and drop this JSON file to the DevTools Performance panel!
  await page.tracing.start({path: 'profile.json'});
  await page.goto('https://pptr.dev');
  await page.tracing.stop();
  await browser.close();
})();

Which produces the results in the image below.

Phoenix v1.5 has been released with LiveView integration. This release makes it easier than ever to build interactive, real-time applications. We put together a quick screencast to show just how much you can accomplish in 15 minutes with LiveView

Editly is a tool and framework for declarative NLE (non-linear video editing) using Node.js and ffmpeg. Editly allows you to easily and programmatically create a video from set of clips, images and titles, with smooth transitions between and music overlaid.

The video in the gif below was produced by sending Editly this JSON config.

The dashboard consists of tiles which are, under the hood, Livewire components. They can update themselves via polling.

You can use any of the pre-packaged tiles or create your own.
