How we do Vue: one year later
It’s been a while since we wrote about Vue. Since that last post, we published a very extensive Vue style guide, after which Vue also put out a style guide, taking inspiration from ours. The style guide has been updated several times as we discover better ways to write Vue. Here are some of the things we discovered.

Rethinking Android app compilation with Buck
Several years ago we built and open-sourced Buck, a build tool designed from the ground up for fast iteration, allowing engineers to compile and run changes quickly. We’ve continued to steadily improve Buck’s performance, together with a growing community of other organizations that have adopted Buck and contributed back. But these improvements have largely been incremental in nature and based on long-standing assumptions about the way software development works. In the end, we completely reimagined the way Buck compiles Java code, unlocking performance gains unachievable through incremental improvements. Today we’re open-sourcing a new feature in Buck that will bring these performance improvements to Android engineers everywhere.

Ten Extras for Great API Documentation
If you manage to create amazing API documentation and ensure that developers have a positive experience implementing your API, they will sing the praises of your product. Continuously improving your API documentation is an investment, but it can have a huge impact. Great documentation builds trust, differentiates you from your competition, and provides marketing value.

Simple React Patterns
I’ve been writing React applications for a few years now, and I’ve noticed that some patterns tend to repeat themselves. In this post, I’ll review these patterns which will summarize about 99% of the React code I write every day. As a sample spec, let’s build an app that fetches information about the Dagobah planet from Star Wars API and shows it to the user.

How Redux Can Make You a Better Developer
I’m not here to promote Redux, but to explain to you why I think that you should learn Redux and how it can make you a better developer in general.

Advanced React Router concepts
In this tutorial, I’ll highlight some advanced React Router concepts like code splitting, animated transitions, scroll restoration, recursive path, and server-side rendering.

Why we are not cross-platform developers
Here at Pixplicity, where we’ve been making apps for over six years, things are no different: though we started out exclusively as native Android developers before we offered full-spectrum solutions, over the years we’ve tried and tested many of the cross-platform solutions out there, like PhoneGap, Xamarin and React. In the end, we’ve always preferred native solutions for both Android and iOS. Let me try to explain our preference in this post. 另附:React Native vs Real Native Apps.

Why Stream Stopped Using .IO Domain Names for Production Traffic
Over the past year, IO domain outages have been the number one reason our customers couldn’t use Stream. Specifically, the outage on September 20th, 2017 turned out to be a major headache. This article will go into the details behind the .IO domain name reliability issues and how we’re working around them.

Deploying IPv6 in Dropbox Edge Network
In this article, we share our experiences and lessons from enabling IPv6 in the edge network. We will cover the IPv6 design in the edge, the changes we made to support IPv6, how IPv6 was tested and rolled out to users, and issues we encountered.

Creating Secure Password Resets With JSON Web Tokens
A JWT provides a URL-safe token that, when generated securely, makes for a more secure password-reset process by ensuring that a malicious user cannot easily generate their own token. This article focused on the password-reset process by securing the password-reset flow with a URL-safe token that is validated with a signature.

CSS is a mess. We all love it, but it’s a mess. I liken it to English: there are a bunch of rules, and you can learn them. But sometimes you’re better off just trying shit and seeing what works and what doesn’t. Magic is a codification of what I’ve learned in that crazy process. The material in this textbook is intermediate-to-advanced. It assumes an understanding of the CSS syntax, cascading and inheritance, and commonly used selectors. It also assumes you’ve had enough experience with CSS to have learned not to make these common mistakes anymore.

An Update on Reddit’s Redesign
Well, ten months and several rounds of user and moderator testing later, we’re excited to share the very first look at the upcoming redesign. While we still have lots of improvements to the UI, feature set, and moderation flow still in the works, we’re excited to start by sharing a preview of two of the most important features in the redesign: a new set of community styling tools and an easier way for users to post to their favorite communities.

Creating a Star to Heart Animation with SVG and Vanilla JavaScript
In my previous article, I’ve shown how to smoothly transition from one state to another using vanilla JavaScript. The last example showcased making the shape of a mouth to go from sad to glad by changing the d attribute of the path we used to draw this mouth. Manipulating the path data can be taken to the next level to give us more interesting results, like a star morphing into a heart.

Simple Tips to Improve User Testing
Usability testing involves observing users as they use a product. It helps you find where users struggle and what they like. There are two ways to run a usability test: Moderated, in which a moderator works with a test participant; Unmoderated, in which the test participant completes the test alone. We’ll focus on the first, but some of the tips mentioned can be applied to both types of testing.

Feature Visualization
How neural networks build up their understanding of images. Neural feature visualization has made great progress over the last few years. As a community, we’ve developed principled ways to create compelling visualizations. We’ve mapped out a number of important challenges and found ways of a addressing them.

Eight years of Go
Since Go was first open sourced we have had 10 releases of the language, libraries and tooling with more than 1680 contributors making over 50,000 commits to the project’s 34 repositories; More than double the number of contributors and nearly double the number of commits from only two years ago. This year we announced that we have begun planning Go 2, our first major revision of the language and tooling.

Noel - A universal, human-centric, replayable event emitter
The world just like software is full of events. Sometimes these events occur while we are busy doing other things. Wouldn’t it be nice to have a way to replay all events? Noel is the way. By being able to replay events we can design reactive systems without having to worry about timing.

Announcing Prometheus 2.0
Nearly one and a half years ago, we released Prometheus 1.0 into the wild. The release marked a significant milestone for the project. We had reached a broad set of features that make up Prometheus’ simple yet extremely powerful monitoring philosophy. Since then we added and improved on various service discovery integrations, extended PromQL, and experimented with a first iteration on remote APIs to enable pluggable long-term storage solutions. But what else has changed to merit a new major release?
