Don't know where you get the idea of an extra request from. What they have implemented is the srcset attribute (from the WHATWG HTML spec), which means that authors can write e.g.

<img alt="Slashdot" src="slashdot_logo.png" srcset="slashdot_logo_big.png 2x">

and the browser will then choose based on the viewport size and resolution which URL to load (whereas browsers that don't support this attribute will just load what's in src). In this case, it would load the big image if the resolution was at least 2*96dpi.

So W3C is dividing it into HTML 5 and CSS 3 and its .1 counterparts for the more experimental things which HTML5test.com look at.

Where did you get this from? The grandparent post is correct; after 2.1, CSS is divided into modules that advance individually. For instance, there is a Backgrounds and Borders module which has a level 3 spec and a level 4 spec (most of the level 4 stuff is not yet mature enough to implement). There isn't really any monolithic "CSS 3" thing, let alone "CSS 3.1".

Whatg tries to put it all together in html 5 and css 3. That is the confusion.

WHATWG's HTML spec is simply called the "HTML Living Standard", they don't use a version number at all. And the WHATWG doesn't specify anything in "CSS 3".

Among the browsers mentioned, Chrome was really the only one "lying about"/inflating its version number. IE and Opera has been around much longer, so it shouldn't be a surprise that they have released more versions.

I made a graph of browser version timelines.

Starcraft, Diablo 1/2 etc are truly great games. But after I switched to Linux, I have stopped buying Windows titles.

I keep my eyes open for games with Linux clients, for instance I've picked up several games with id Software's logo on the box (Doom 3+RoE, Quake 4, RTCW, Q2). To be honest I don't think many of these would have made the cut had I still been a Windows gamer, but I wanted to make a point of supporting them because of their Linux-friendliness.

I would love to buy your products if they were available on Linux.

(Opening up the source of old games would be nice too, and could help keeping them playable even in the distant future.)
