How to install Opera 10 Alpha under Linux

Wednesday, December 17th, 2008

Opera claims that a alpha or beta version will not interfere with a standard installation, but that’s mainly true for Windows. For Linux you have to be a bit more carefull, but still it’s easy.

How do you install the latest Opera Alpha/beta version on a Linux/ Ubuntu box? The download page doesn’t offer the dedicated Ubuntu versions like it does for main versions. But don’t worry, it is easy.

There a several version for download, for AMD64 bits for 64 bits systems or intel-linux for 32bits setups. Make your choice.

Then you have to choose for different GCC and QT versions. GCC stands for GNU Compiler Collection the standard compiler for most Linux systems. QT refers to the LIBQT libraries. Qt is a cross-platform C++ application framework. Qt’s primary feature is its rich set of widgets that provide standard GUI functionality. You can check your versions in the Synaptic Package Manager and choose.

I took the easy way: I simply downloaded the bundled version with the latest versions, and it worked.

Don’t take the RPM or DEB’s packjages. They will be installed with installers like dpkg and interfere with your existing Opera browser. Choose the gz or bz2 packages instead.

Download the packages to your home folder, extract, and run!

To extract the bz2:

tar -xvjf opera-10.00-4102.gcc4-bundled-qt4.i386.tar.bz2

Then:

cd opera-10.00-4102.gcc4-bundled-qt4.i386/

And run:

 ./opera

That’s all! Opera runs just fine. And the new rendering speed is fast, really fast. I noticed that scrolling is not always smooth on complicated SVG pages, but hey, it’s a alpha. Webfonts are cool. Expect a demo here soon.

SVG Gradient Background in Opera (9.6)

Monday, September 15th, 2008

Intro

There is a lot going on in the CSS3 and HTML5 development. Rounded borders (radius) and multi-image backgrounds are both supported in latest Safari/Webkit and Firefox beta’s. Opera has always been a pioneer with CSS and SVG support and has chosen to walk a more interesting road. Opera gives you the opportunity to treat SVG objects as any other image including background image declared in CSS. An SVG-object as a background options gives you all the power of radius and multi-image background plus a lot more: stars, ellipse, triangles, multi-images, animated background and easy javascript driven user customisable backgrounds.

Examples

Let’s have some examples.

SVG backgrounds are really nice and powerful. SVG can be used for gradients, rounded corners, watermarks, graphics and even animated backgrounds. SVG can also be used for list style images for and <li> elements in ordered and unordered lists.

There is a bug though. If you give a div a border there are rendering issues as you can see here.
