Changes in Opera’s user agent string format (via) How depressing... Opera 10 will ship with 9.80 in the User-Agent string because badly written browser sniffing scripts can’t cope with double digits. # 28th May 2009, 1:16 am

and now... Opera. Jon Hicks is joining Opera as Senior Designer. I absolutely cannot wait to see what he comes up with there. # 9th October 2008, 6:39 pm

A browser sniffing warning: The trouble with Acid3 and TinyMCE. Opera recommend “bug detection”, a step up from object detection and browser sniffing where your JavaScript includes mini unit test style fragments of code designed to test if buggy behaviour you are working around still affects the user’s browser. # 4th July 2008, 8:24 am

Ian’s Acid 3, unlike its predecessors, is not about establishing a baseline of useful web capabilities. It’s quite explicitly about making browser developers jump—Ian specifically sought out tests that were broken in WebKit, Opera, and Gecko, perhaps out of a twisted attempt at fairness. But the Acid tests shouldn’t be fair to browsers, they should be fair to the web; they should be based on how good the web will be as a platform if all browsers conform, not about how far any given browser has to stretch to get there.

Opera and the Acid3 Test. Screenshot shows 100/100 (live code or it didn’t happen!)—Opera’s codebase must be in extremely good shape to fix so many issues so quickly. # 26th March 2008, 10:47 pm

Opera 9.5 alpha, Kestrel, released. “With history search, Opera creates a full-text index of each and every page you visit, and when you go to the address bar, you can simply start entering words you know have been on pages you’ve visited before, and items matching your search show up.” I just tried this; it’s magic. I’m switching back to Opera from Camino. # 16th September 2007, 8:34 pm

Opera 9.5 (Kestrel). The latest Opera alpha includes a bunch of CSS3 features (including an almost full implementation of CSS3 Selectors) as well as the ability to use SVG for scalable background images. # 4th September 2007, 10:49 am

Sticking with Opera 9

It’s been a month and a half since I started using Opera 9, with a promise to report back later. I’m still using it, although some of the things I liked initially have faded while others have emerged.

Opera Mini 2.0

Just as I was getting thoroughly sick of the whole X-2.0 trend along comes a product I can really get excited about. Opera Mini 2.0 is a truly lovely piece of software. It’s a free web browser for your phone, accompanied by a free proxy:
