  • Not every bit of code you write needs to be optimal

    It's easy to fall into the trap of obsessing about performance and try to micro-optimize every little detail in the code you're writing. Or reviewing for that matter. Most of the time, this just adds complexity and is a waste of effort.

    If a piece of code only runs a few (or even a few hundred) times a second, a few nanoseconds per invocation won't make a significant difference. Chances are the performance wins you'll gain by micro optimizing such code won't show up on a profile.

  • Making tab switching faster in Firefox with tab warming

    Since working on the Electrolysis team (and having transitioned to working on various performance initiatives), I’ve been working on making tab operations feel faster in Firefox. For example, I wrote a few months back about a technique we used to make tab closing faster.

    Today, I’m writing to talk about how we’re trying to make tab switching feel faster in some cases.

3 big steps toward building authentic developer communities

As more software businesses are selling open source products, we've seen a corresponding rise in the emphasis of building out developer communities around these products as a key metric for success. Happy users are passionate advocates, and these passionate advocates raise overall awareness of a company's product offerings. Attract the right vocal influencers into your community, and customers become more interested in forming a relationship with your company. Doing community building the right way, however, is a delicate balance. Undercut the needs of your user community in favor of driving sales, and your company will face a decrease in adoption and unfavorable brand awareness. Meanwhile, too little focus on the bottom line isn't good for the company. So how can this tension be balanced effectively, especially in a world in which developers are the "new kingmakers" and meeting their sensibilities is a cornerstone of driving corporate purchasing decisions? Over the past year, I've thought a lot about how to do effective community building while building the business bottom line. In this article, I'll outline three big steps to take toward building authentic, productive, sustainable developer communities.

Amid the 20th anniversary of open source, Tim O’Reilly warns that platform companies built on open-source software have lost their way

It’s rare to hear Chinese philosophy quoted on stage at a software-development conference. But O’Reilly Media founder and CEO Tim O’Reilly invoked the words of Lao Tzu Wednesday morning during the opening keynotes at OSCON 2018 in hopes of convincing those in attendance — many of whom work for the big internet platform companies of our time — that the tech industry needs to return to the spirit of openness and collaboration that drove the early days of the open-source community before it is too late. “We have an opportunity with these next generation of systems, to rebuild, to rethink the future, to discover what does it mean to get these systems right,” O’Reilly said. If the first era of the internet was dominated by open protocols, and the second era was dominated by the rise of huge platform companies like Amazon, Google, and Facebook, the third era we’re about to enter presents a chance to get it right again.
