Impressions from the Opera Software conference. Novosibirsk

    So, yesterday, November 7, 2008, he successfully persuaded classmates to attend the Opera workshop. And all because I am a member of Opera Campus Crew , or in other words, a representative of Opera at my university.
    I liked the seminar as a whole, there were interesting moments. I’ll tell you briefly about them :)

    The conference began with what was told about the Opera company, about personnel, the result is as follows:

    The company employs about 500 people, over the past year 100,000,000 of their browsers have been downloaded, which of course is less than Firefox, but I think it's still good. They continued with a story about Opera Mobile, boasted that they managed in 2005 to create a mobile browser that can work correctly with Ajax. At the moment, Opera Mobile has more features for WM and UIQ, but soon it is planned to continue development for S60. And of course they didn’t forget about Opera Mini, it has as many as 20 million users. Russia leads in the number of users, which is good news :). By the way, 50% of Russian GPRS traffic is spent just by opera mini.

    Then we did not forget to mention the Internet as a platform for applications, the main advantage in their opinion is that the Internet is accessible everywhere, and it is flexible. We talked about WEB standards (W3C, etc.), I think it’s not worth talking about since everything is clear already. They praised the fact that Opera itself is involved in the development of web standards, as many as 25 employees are doing just that, mostly W3C of course.

    The hosts of the seminar also did not forget about their features - Widgets were said by the hosts, a lot of good things were said in their favor, for example, that they are easily portable to different platforms, can work both online and offline, they only download changed data from the Internet , which of course is relevant for users with tariffs for paying for traffic and “mobile” users, and creating widgets is quite simple according to their application.

    They talked about Dragonfly (Firebug for Opera), the convenience is that the debugger can work remotely (Suppose debugging a widget on a mobile phone is difficult and inconvenient, and with such features you can debug widgets directly from a computer). Scope works according to such a scheme - as I understand it, the interface in each opera with the kernel version 2.1 is used for remote debugging. The Scope API has not yet been finalized, but they promise to make it public soon. Very useful feature: you can run two instances of the debugger: Scheme:


    | Host | | Client |
    | Scope | -- | Proxy |

    The next topic of the conference was various graphics, they started talking about PNG. What is it like a free GIF replacement supporting animation! (I didn’t know about it) and standardized in W3C a very good format for WEB. But there is a big minus, like all formats that store a bitmap image - at high magnification, the picture does not scale, and you can see small squares that look pretty ugly. Therefore, they offer vector SVG, which does not lose its quality even at a large scale. Intermixed with XHTML, you can create quite interesting interactive animations, for example, as analog clocks showed at the conference. From the SVG theme, we smoothly switched to the topic of drawing, although it is more difficult to draw with it, it has more features. (Demonstrated 3D shooter :) Here is a photo, forgive me for the quality)

    That’s basically all, I think it will be interesting to those who wanted to go, but couldn’t.
    PS Oh yes, they also presented a disk with an Opera, a sticker, a corporate pen and a package. Here.
