Google Chrome Google, faced with concerns over Microsoft using it's browser marketshare to marginalize the search engine, have decided to take the fight directly to them. Google Chrome is an open sourced browser based on the Webkit HTML engine, but adds a new Javascript engine, and some UI changes. To advertise it, they've enlisted Scott McCloud to make a comic showing the browser's features. The release date is Wednesday, but watch this space.

If Earthlink starts killing pop-up ads will a trend emerge? I hate pop-up ads, but they must have some effect because I see more and more. I can see the logic in Earthlink's attempt to gain customers by promising to block pop-up ads, but will it have an effect? I can get other pop-up killers without getting it from Earthlink. Why don't they address spyware and attack web advertisers where they live?

Is anyone else getting really irritated over the no right click java-scripts? The thing does mostly nothing, if you wanted to steal something, you could through the source code, and most of the sites that are tacky enough to place it in there have really crappy graphics anyway. What I use the right click for is opening a link in a new windows, if there's a list of links and you go through them one by one. *Sigh*

Customization of a page was never easier. Mark Newhouse of iBook, iMac, iBlog, has come up with this really cool way of skinning the blog using CSS via a nifty adaptation of a script by Porter Glendinng. Now if we could mix this concept with Jason's modification via cookies, you'd get a skinnable site rather than a skinnable page using just CSS and Javascript. [Found the site via Zeldman]

Jason found a pretty cool javascript/CSS hack so I took a stab creating a bizarro kottke one (bookmark and try it at kottke.org). I think it improves the page :). This might be a killer hack for usability tweaking. If you set your backgrounds dark with light, 28px text for easy reading, few web pages follow that convention. Here's your chance to see things your way. Can anyone think of any other uses for this?

links open windows is a bookmarklet I wrote which evolved from my 'links open windows' checkbox. Drag this to your toolbar (like you did with deepleap) and with a click you can cause the links on any page to spawn new windows. In a few cases (like the Guardian weblog) you might want to do the opposite, and follow links in one window. Enjoy.
