Apple — Anne’s Blog
I have often wondered what it would be like to work for Apple and now I have the privilege to find out! There’s a lot of amazing people on the WebKit team I have had the pleasure of meeting and collaborating with. Getting to do a lot more of that will be terrific. Writing this it’s still somewhat difficult to comprehend it’s actually happening. Apple itself is the sole institution that develops co
Leaving Mozilla — Anne’s Blog
I will be officially leaving Mozilla on the last day of June. My last working day will be June 16. Perhaps I should say I will be leaving the Mozilla Corporation — MoCo, as it’s known internally. After all, once you’re a Mozillian, you’re always a Mozillian. I was there for a significant part of my life — nine years, most of them great, some tough. I was empowered and supported by leadership to mo
Testing standards — Anne’s Blog
13 November 2017 At a high level, standards organizations operate in similar ways. A standard is produced and implementations follow. Taking a cue from software engineering, WHATWG added active maintenance to the mix by producing Living Standards. The idea being that just like unmaintained software, unmaintained standards lead to security issues and shaky foundations. The W3C worked on test suites
Making the DOM faster — Anne’s Blog
25 May 2016 There is a pretty good comment on Hacker News (of all places) by nostrademons explaining why the DOM is not slow. Basically, all the DOM mutation operations are pretty trivial. Inserting and removing nodes, moving them around, setting an attribute, etc. It’s layout that takes a while and layout can be synchronously triggered through APIs such as offsetWidth and getComputedStyle(). So y
HTML components — Anne’s Blog
29 April 2016 Hayato left a rather flattering review comment to my pull request for integrating shadow tree event dispatch into the DOM Standard. It made me reflect upon all the effort that came before us with regards to adding components to DOM and HTML. It has been a nearly two-decade journey to get to a point where all browsers are willing to implement, and then ship. It is not quite a glacial
Network effects affecting standards — Anne’s Blog
29 April 2016 In the context of another WebKit issue around URL parsing, Alexey pointed me to WebKit bug 116887. It handily demonstrates why the web needs the URL Standard. The server reacts differently to %7B than it does to {. It expects the latter, despite the IETF STD not even mentioning that code point. Partly to blame here are the browsers. In the early days code shipped without much quality
Upstreaming custom elements and shadow DOM — Anne’s Blog
29 March 2016 We have reached the point where custom elements and shadow DOM slowly make their way into other standards. The Custom Elements draft has been reformatted as a series of patches by Domenic and I have been migrating parts of the Shadow DOM draft into the DOM Standard and HTML Standard. Once done this should remove a whole bunch of implementation questions that have come up and essentia
Custom elements no longer contentious — Anne’s Blog
8 February 2016 I was in San Francisco two weeks ago. Always fun to see friends and complain about how poorly Caltrain compares to trains in most civilized countries. Custom elements day was at Apple where you cannot reasonably get to via public transport from San Francisco. The “express” Caltrain to Mountain View and a surged Uber is your best bet. On the way back you can count on Ryosuke, who kn
W3C forks HTML yet again — Anne’s Blog
21 January 2016 The W3C has forked the HTML Standard for the nth time. As always, it is pretty disastrous: Erased all Git history of the document. Did not document how they transformed the document. Issues of mismatches have already been reported and it will likely be a long time, if ever, before all bugs due to this process are uncovered, since it was not open. Did not discuss plans with the wide
Firefox OS is not helping the web — Anne’s Blog
13 January 2016 Mozilla has been working on Firefox OS for quite a while now and ever since I joined I have not been comfortable with it. Not the high-level goal of turning the web into an OS, that seems great, but the misguided approach we are taking to get there. The problem with Firefox OS is that it started from an ecosystem parallel to the web. Packaged applications written using HTML, JavaSc
Asynchronicity — Anne’s Blog
12 August 2014 There is ever more asynchronicity within the web platform. Asynchronous being some set of steps that could be performed in parallel with JavaScript running in a given environment such as a window or worker. Fetching networked resources, computing crypto, and audio processing, are examples of things that can be done asynchronous. The JavaScript language does not really know about thr
Web platform and JavaScript — Anne’s Blog
13 January 2015 As most object-oriented systems, objects within the web platform consist of internal slots (private state) and public members that expose and manipulate the internal slots. The public members are shared through a common prototype object. The internal slots are allocated at object-creation time. In contemporary implementations the internal slots are typically a C++ (nay Rust) affair
Simplified initializing of synthetic events — Anne’s Blog
23 June 2011 The DOM event model allows authors to listen and act on user-agent generated events. It also provides a way for authors to dispatch their own events. Typically this is known as dispatching synthetic events. Here is an example: var ev = document.createEvent("UIEvent") ev.initUIEvent("test", false, false, null, 1) // obsolete document.dispatchEvent(ev) With the current design each event
Disabling the WebSocket protocol — Anne’s Blog
8 December 2010 Adam Barth reported on vulnerabilities with the current WebSocket protocol handshake. Reportedly you can poison the cache of transparent/intercepting proxies affecting all users of that proxy. So rather than e.g. http://www.google-analytics.com/ga.js you would get a JavaScript file from an attacker. This attack affects Flash and Java as well, but we have higher standards for browse
