UX & User Research

Market Insights

Desktop / Platform


  • The Chromium team expanded the Chromium Security Rewards Program, by increasing its scope to cover the Chromium OS.
  • The new Chrome Beta release enables GPU-accelerated rendering of 2D canvas content, and also enables WebGL acceleration for people with older GPUs using Swiftshader, a software rasterizer that Google licensed from TransGaming. This should make for significant performance improvements on systems like Windows XP.
  • Chrome’s dev channel features an updated V8 Javascript engine that offers initial support for lexical scoping, collections, weak maps, and proxies.
  • Google also released a Field Guide to Web Applications that offer a high-level, architectural overview of how to design web applications. Their HTML5Rocks site was updated, and features an excellent detailed overview of the architecture of the Chrome and Mozilla browsers.
  • Chrome 17 stable was released. 20 security bugs were fixed — 1 critical, 8 high, 5 medium, and 6 low. A significant number were detected with AddressSanitizer, a fast memory error detector.
  • Chrome’s Dev Channel release has a few interesting new features, including using Google’s servers to conduct spellchecking for entered and pasted text.
  • The Sencha team conducted an initial review of Google Chrome for Android, giving it high marks. It notes that SunSpider performance is little different than other browsers and suggests that it is now time to shelve that particular benchmark test.


  • The latest snapshot of Opera 12 offers support for Do Not Track and a substantial number of SSL performance optimizations.


  • Microsoft released a Critical update for MSIE 6, 7, 8, and 9. The vulnerability would allow remote code execution from a specially constructed web page. The update itself had to be updated shortly afterwards after it incorrectly reported that was infected with the Blackhole Exploitation Kit.
  • MSIE 10 will allow full support for Cross-Origin Resource Sharing for XMLHttpRequests.
  • In a 9,000 word blog post, Microsoft’s Windows president Steven Sinofsky divulged a slew of details on Windows on ARM. Microsoft plans to have ARM PCs available when other Windows 8 computers are available, and the company will also include desktop versions of optimized Office 15 applications. Windows 8 ARM PCs will also never turn off, instead going into a standby mode that should last for weeks.


  • HP released the source code to Isis, the WebOS browser, which apparently offers “unrivaled speed and standards compliance”.


  • Webmonkey has a good summary article describing the issues and positions in the debate as to whether other browsers should support -webkit-prefixed CSS properties. (Also, Tantek’s interview at A List Apart.
