Futurice Tech Weeklies

In this edition of Tech Weeklies, Olavi shares his learnings from creating and maintaining a Sailfish OS app for tracking working hours, called Working Hours Tracker. It was a project he started in 2014 and has been developing and maintaining it ever since. The most recent version of the app was released in February 2021.

At the time of starting this project, Olavi had been studying for a few years, and had little real world experience in software projects. As we all know, most of the learning happens at work or when doing some side projects. His limited experience and knowledge led to some of the interesting mistakes made during the project. This talk covers some of those mistakes and the lessons he learned from them.

The creator of Node.js, Ryan Dahl, released a new shiny runtime for Javascript and TypeScript in 2018 called Deno. Release 1.0 finally came out in 2020, and eager developers flocked to use Deno in production. Or did they?

In this TechWeeklies talk, Minna briefly introduces the features and design aims of Deno. Then she addresses the obligatory question "how does it compare to Node?". The talk also includes a live coding demo to showcase how easy it is to use Deno for your daily ad-hoc scripting needs.

Getting a modern JS project from git to running in a terminal takes ages. There is the installation of dependencies, running the server, running the bundler, maybe a type-checker, the CSS pipeline. There are watchers watching watchers, and the whole thing makes both my head and your computer's fans spin. The setup is yet more complex once you start adding multiple projects in one codebase, when you think of Server-Side Rendering and so on.

 

This delay has a real impact on people being able to contribute to the codebase, especially when it comes to iterative UI work. Trying to make things faster in the current (by some definition) model hits diminishing returns, and takes active time and budget to do right. For example, over three years Fotis has reworked his current project's pipeline four times, and while it was faster each time, it still can be a challenge!

 

In this talk, Fotis tries a different approach. He will give you a brief tour of modern tools that rethink how dependencies are bundled in development, and the very real gains that they offer.

Some people suffer physically when they encounter something like parallax scrolling or horizontally scrolling text. It can cause them nausea, dizziness, or other symptoms that can last for hours. These people can turn the "reduce motion" settings ON from the system level. As a developer, you have tools to respect that setting.

In this talk, Eevis discusses why motion can trigger the symptoms mentioned above and what kind of animations can be problematic (this can be surprising for some!). She also shows you how to respect the user’s settings with the prefers-reduced-motion media feature.

Error Boundary is a React component that catches JavaScript errors anywhere in their child component tree, which enables graceful handling of runtime errors and offers a way to recover from them. The way it is used makes it important to have it well-tested.In this talk, Layla talks about what error boundaries are and why they are a valuable tool in your React toolbox. She also builds you an example of how to test those error boundaries with React Testing Library using Test-Driven Development.
