Last fall, after nearly two years of research and discussion, we made our first major step toward cooperatizing: Bocoup is now a member of The […]

  • Co-op Series Part I: Our decision to pursue worker-ownership

    Sheila Moussavi - September 22nd, 2022

    Bocoup is incorporated in the United States – a country with no worker safety net. The damning scarcity of federally protected labor rights means that employers are often the ones determining whether workers get quality health care, a fair wage, or time off after having a child. Companies in most states are protected by anti-worker […]

  • What if Technology was Created for the Benefit of All Life on Earth?

    Lazarus Letcher - April 22nd, 2022

    Earth Day 2022 My generation was raised in the bosom of corporate greenwashing. Every year on Earth Day I remember gathering with my classmates to learn about our role in protecting the environment. We were constantly reminded of the dire need for us to separate our recyclables (and to shame our parents in to doing […]

    Mike Pennisi - January 29th, 2018

    Regular readers of this blog are no strangers to free and open source software.

  • Showing Missing Data in Line Charts

    Peter Beshai - September 20th, 2016

    While working on visualizing the results of internet speed test data for Measurement Lab, it became clear that there wouldn’t always be data for every geographic location on every single day. We might go several days without meeting a minimum threshold of tests, meaning there would be gaps in our data. This is a pretty […]

  • How BoxArt Provides Fast DOM Animations

    Lyza Gardner and Z Goddard - September 13th, 2016

    Our last article about BoxArt showed how to use BoxArt’s Animated component to animate a tile-dropping game built in React. This time, we are going to look at some features of how Animated optimizes animations for performance. The Beastliness of Layout Thrash There’s a performance nightmare constantly threatening when you’re animating in the browser. As […]

  • Animating React Elements with BoxArt

    Lyza Gardner and Z Goddard - September 8th, 2016

    Have you ever tried writing animations into a website? It’s complicated. There’s lots of room for error, and no tool seems to fill every animation need. Recently, while writing some DOM-based games, the Bocoup team realized there wasn’t existing software for all of the projects’ animation needs. To help fill the gaps, Bocoup created BoxArt, […]

  • Introducing BoxArt: A Library to Help Build HTML Games

    Z Goddard - May 23rd, 2016

    We’ve been busy building some Open Web Games at Bocoup. As we did so, we realized there was a dearth of resources for making performant, fun web games using the DOM. Most material aimed at game developers focuses on canvas rendering, and there aren’t many resources for web developers that show them how to use […]

  • Towards “Responsiveness” with d3.chart.js

    Irene Ros - October 21st, 2013

    While data visualization is growing as a medium on the Open Web, practitioners of the field still struggle to make data visualization “work” on different screens. The question “how do I render at different sizes?” is an important one, but only tackles a portion of the greater challenge of “what does it mean to create […]

  • Third-Party JavaScript Development: CSS Defensive Techniques

    Mike Pennisi - April 17th, 2012

    (In a previous article, I introduced a convenient method for shipping stylesheets with your third-party JavaScript application.)

  • Third-Party JavaScript Development: Optimizing CSS Delivery

    Mike Pennisi - April 10th, 2012

    As a practicing masochist, I have recently developed an interest in third-party JavaScript application development. I’m not alone: third-party JavaScript (or “3PJS”) applications are becoming more and more common on the web (see Disqus, Optimizely, and Google Analytics, for instance). Like any developing methodology, best practices are constantly being explored and re-defined. In this article, […]

  • Javascript Web Workers: From Basics to jQuery.Hive, Part III

    Rick Waldron - May 18th, 2010

    I’m a jQuery enthusiast. Maybe even an evangelist. So I decided to make workers easy for my fellow jQuery developers – and thus was born the jQuery.Hive. Inititally it began it’s life as PollenJS a jQuery-looking library of functions that were light, useful and thread-safe. This was before the WebKit implementation existed so everything was […]

  • Javascript Web Workers: From Basics to jQuery.Hive, Part II (Browser Implementations)

    Rick Waldron - May 18th, 2010

    As I mentioned in Part I, the Web Worker API is available for use in Firefox 3.5+, Safari 4+ and Chrome 4+, however the implementations are inconsistant. This has been completely overlooked by every single tutorial I’ve found. The issue revolves around the accepted argument to postMessage() (from both the main window and the worker). […]

  • Faster Javascript – Part 2

    Alistair Macdonald - March 10th, 2010

    In Faster Javascript Part 1 we compared a three methods for evaluating a string of alien DNA.

Testing methods is one thing, but there’s more to writing fast code than just testing. For example: order […]

  • Bocoup’s Commitment to Privacy

    Lola Odelola - May 21st, 2024

    When the Web was created, it was an unregulated digital space where anyone with access could create, contribute and share.

  • Making Zoom Calls More Accessible

    Lazarus Letcher - March 28th, 2023

    Our co-worker thought we were heartless monsters. This is a slight exaggeration, but an important lesson about what gets lost in translation when apps aren’t entirely accessible. During an experimental Zoom call, we learned that screen readers and the reactions feature aren’t quite compatible. That means that every time during a call when someone mentioned […]

  • Lessons Learned from a Year of Testing the Web Platform

    Mike Pennisi - July 22nd, 2019

    The web-platform-tests project is a massive suite of tests (over one million in total) which verify that software (mostly web browsers) correctly implement web technologies. It’s as important as it is ambitious: the health of the web depends on a plurality of interoperable implementations. Although Bocoup has been contributing to the web-platform-tests, or “WPT,” for […]

  • Take the MDN Developer & Designer Needs Survey

    Jory Burson - July 16th, 2019

    Today, MDN announced their first-ever needs assessment survey for web developers and designers. The survey takes about 20 minutes and asks a variety of questions aimed at understanding the joys, frustrations, needs and wants of everyday web-makers. Mozilla have committed to making the results of the survey public later this year, and the survey itself […]

  • Optimizing Scratch 3 Pen Blocks

    Z Goddard - July 10th, 2019

    Earlier this year, we shared our work on the launch of Scratch 3.0, a major version of the visual programming environment for children of all ages. The new version of Scratch marked a complete rewrite of the runtime in JavaScript leveraging open web APIs. In our previous post, we enumerated the many performance optimizations that […]

  • Widening the Web with ECMA-402: Our work on the Internationalization Extension to JavaScript

    Valerie Young - May 30th, 2019

    Inconsistencies across browser implementations have caused web authors and users headaches since the dawn of time (or at least Jan 1, 1970), but nowhere has that pain been felt more acutely than in the realm of language and regional internationalization and localization. We have an inclusion gap on the web. Web authoring tools structurally exclude […]

  • Glitching Scratch 3.0 on an Embedded Web Game Console

    Boaz Sender, Corey Frang, and Amal Hussein - May 29th, 2019

    Today, we are excited to announce our partnership with JoyLabz, which began in 2017 and has centered around the development of a new game console called GameBender. JoyLabz, developers of Makey Makey and Drawdio, and founded by former Lifelong Kindergarten researcher Jay Silver, has been an incredible partner. We are excited to finally share the […]

  • Test262 Helps Advance JavaScript Proposals to Standardization

    Seth Thompson - April 11th, 2019

    Test262 is a conformance test suite for ECMAScript, the programming language on which JavaScript is based. Containing 36,103 individual tests at the time of this writing, Test262 ensures that different implementations of the language, such as the JavaScript engines in web browsers or stand-alone runtimes like Node.js or Moddable XS, agree on the minutiae of […]

  • Porting Scratch from Flash to JavaScript: Performance, Interoperability and Extensions

    Corey Frang - February 28th, 2019

    Last year we formed a team focused on using the growing number of new web APIs to build multimedia applications that push the edge of the web platform. Our main work in this area over the last 2 years has been with the wonderful team behind Scratch at MIT’s Lifelong Kindergarten Group (LLK), and with […]

  • The Eight-Month Omelette: adding a feature to one million conformance tests

    Mike Pennisi - December 5th, 2018

    The web-platform-tests project (WPT) houses over a million tests written to ensure our browsers provide a consistent experience of the web. WPT predates most of today’s popular JavaScript testing frameworks, so it implements one of its own: testharness.js. In December of 2017, I offered to extend testharness.js with a new feature. No one expected this […]

  • Announcing Test262 Report

    Rick Waldron and Boaz Sender - November 7th, 2018

    Today we’re launching Test262 Report to provide JavaScript developers with up-to-date information on the state of new and existing language features across implementations. Test262 Report is based on daily runs of Test262, the ECMA-262 (“ECMAScript” or “JavaScript”) test suite, in nightly builds of JavaScript engines, and visualizes at-a-glance status of feature implementation progress. Taking a […]

  • New Test262 Import and Runner in WebKit

    Rick Waldron - October 16th, 2018

    Bocoup recently facilitated an update to the WebKit project’s interaction with Test262. In this article, I’ll cover what this means for the WebKit project and the JavaScript ecosystem, as well as what exactly has been done in the WebKit project to help make this process more repeatable. Test262 is a project maintained by Ecma’s TC39. […]

  • The State of Fieldset Interoperability

    Simon Pieters - September 19th, 2018

    We recently started working with browser implementers to improve the state of fieldset, the 21 year old feature in HTML, that provides form accessibility benefits to assistive technologies like screen readers. It suffers from a number of interoperability bugs that make it difficult for web developers to use. Here is an example form grouped with […]

  • WPT Workshop Report

    Mike Pennisi and Simon Pieters - July 19th, 2018

    On June 13, operations screeched to a halt here at Bocoup. The phones were ringing, but we didn’t answer them. Packages delivered to our door went ignored. Chicken eggs piled up. All hands were on keyboards, collaborating on the web-platform-tests project. We’ve been participating in WPT for years, largely in collaboration with the Chromium, Gecko […]

  • Introducing Gaia

    Boaz Sender - July 9th, 2018

    I’m excited to share that our technical partnerships team has developed a deeper focus on graphics and interactive application programming, a focus area which we are affectionately calling Gaia. As of today, Technical Partnerships is now Graphics and Interactive Applications (Gaia for short). In many ways this is a reflection of what this team has […]

  • Adapter Pattern – A Must for Vendor & Service Integrations

    Brendan McLoughlin - May 1st, 2018

    Software development is a costly process. Requirements need to be gathered, decisions need to be made, and resources need to be scheduled to write the software. All of these steps require an investment of time and money to get a feature to the point where it starts bringing value to a business. After the feature […]

  • Lorin, Redrafted

    Mike Pennisi - December 1st, 2017

    Our pal Lorin Bond has headed out Californee Way to seek her fortune in her home state. She’s done a lot of good around these parts over the past few years, and we wanted to make sure everybody knows about it. From the get-go, we all knew we wanted to work with Lorin. For some, […]

  • I Slipped on JavaScript’s Banana Peel

    Mike Pennisi - November 20th, 2017

    Think of the last time you goofed up on the job. Maybe you forgot to clean out the microwave in the break room. Maybe you hit “Reply All” when you really meant “Reply.” Or maybe you nodded off during an all-hands meeting. Probably your mistake was a little less banal than any of that, but […]

  • The Other Bob

    Mike Pennisi - October 13th, 2017

    Bob Holt was an easy hire. He had plenty of experience as a front-end developer. He was engaged in the Boston web development community, meaning he was no stranger to the Bocoup Loft. And beyond just wielding open source software, Bob maintained an offering of his own: Keel.js. He was doing us proud from the […]

  • This One Outgrew Her Shell

    Mike Pennisi - October 1st, 2017

    Can you tell me what EBITDA stands for? No? Okay, well, how many varieties of sea slugs can you name? None?! Clearly, you have never worked with Jasmin Jata. She taught us all this and more over the past 3 years. Although Jasmin joined us with a good deal of experience under her belt, she […]

  • A Powellful Farewell

    Mike Pennisi - September 14th, 2017

    To the best of our knowledge, Laura Powell is the only person to lie to us while interviewing. She shared a tall tale about an unfortunate series of events during a wedding, and she challenged us to spot the fib. While deception was not a tool she would employ again, her knack for storytelling was […]

  • Moving forward with the Open Web

    Jory Burson and Boaz Sender - September 8th, 2017

    We’re announcing some big changes to our teams and a new focus area for Bocoup. First, we have made the difficult decision to close our design and data visualization services in order to plant deeper roots as an open web engineering company. As a result, many of our teammates have moved on to pursue other […]

  • The Next Steps For TC39

    Leo Balter - August 10th, 2017

    It’s been more than an year since I started attending TC39 meetings, and this most recent meeting felt much like the first, as I faced a new personal challenge: I went there as the acting chair. TC39 is a group of almost 50 highly skilled professionals, each with very strong positions on the existing form […]

  • The Caper of the Flaky Test

    Mike Pennisi - August 3rd, 2017

    The test showed up on my desk just like any other. There I was, working with Google’s Web Platform Predictability team to find so-called “flaky” tests in the venerable Web Platform Tests project. I’d run a hundred or so at a time, over and over again, looking for any that reported inconsistent results. It was […]

  • Keep on inspiring us, Yannick!

    Mike Pennisi - July 28th, 2017

    Our pal Yannick has left Bocoup to pursue his interests in data visualization at Google. We’re excited to see what he does next, but we wanted to take a minute to reflect on all the great things we did together over the past four years. Yannick’s reputation precedes him; from the day he started, we […]

  • Accessibility for Robots

    Mike Pennisi - July 26th, 2017

    Maybe you’re not a “people person.” It’s not that you dislike other humans, but you recognize certain realities of your work. Your day job is maintaining a web application, after all, not carousing with your users. You know that accessibility is an important topic, but you haven’t been able to find the time to learn […]

  • Peter Changes Divisions

    Mike Pennisi - July 21st, 2017

    Peter Beshai has hung up his Bocoup jersey so that he can continue to challenge himself in the field of data visualization. We wanted to take a moment to talk about why Peter will always be a member of this team, wherever he plays Peter’s first order of business was creating an interactive experience for […]

    Mike Pennisi - July 18th, 2017

    Following a six-year stint as Bocoup’s leader in data visualization, Irene Ros has struck out on a new path with Google. In this post, we’d like to celebrate her many contributions to Bocoup over the years. Let’s get the obvious stuff out the way, first. Irene started Bocoup’s data visualization initiative with the declaration, “I […]

  • Agile Methods for Tackling Technical Debt

    Matt Surabian - July 14th, 2017

    Managing technical debt is such an important part of software development we include this goal in every contract we send out: Reduce or eliminate technical debt. All complex projects accumulate some form of technical debt. In extreme cases, it can cause project velocity to slow to a crawl. In this post we’ll review a few […]

  • Lyza’s Laser Focus

    Mike Pennisi - June 30th, 2017

    When we first welcomed Lyza Gardner to our team, we knew her to be an especially thorough sort of web developer. Now that she’s struck out on her own, it’s a good time to document how she maintained that reputation during her time at Bocoup. Lyza floored us with a presentation all about the burgeoning […]

  • So Long, ajpiano

    Mike Pennisi - June 28th, 2017

    Adam Sontag came to Bocoup with a reputation for community support. Between his tireless commitment to newcomers in the #jquery IRC channel on freenode.net and his commanding presence on the yayQuery podcast, if you were learning jQuery in 2010, you probably got a tip or two from Adam. (We’d be remiss if we neglected to […]
