I've decided to release a tool I developed for the self quantification system I'm building. svg_graph is a Javascript object that builds timeline graphs and injects them into XHTML documents.

I've tested it on Firefox, Chrome, Safari and Opera, and it should work on any browser that supports XHTML and SVG. Unfortunately IE doesn't support either, so it won't work there.

QT now LGPLed

I'd been hoping this might happen ever since Nokia bought Trolltech, but now it's happened.

Qt, the cross platform library most widely used as the base for KDE can now be used by all projects, regardless of the license they use. Qt is an awesome library, and Trolltech was certainly justified in charging for commercial licenses, but it effectively nixed any non-open source activity on the KDE platform. If you just needed Qt for KDE support, the licensing fees were just too onerous to consider. (They stopped advertising them at some point, but IIRC they were about $4k per developer per year.)

This didn't nudge people to opening proprietary software, it just pushed them away from KDE to Gnome/GTK. Now that this hurdle is gone, both projects can compete on their merits rather than their licenses.

Google releases a browser

Today Google released their new browser, Chrome. It's very pretty, sleek, and it implements an idea that's a been sorely needed in the browser space for a long time.

Chrome separates each tab into its own process, so if a page or plugin (*cough* Flash *cough*) causes a crash, it can only take out that tab. The rest of your tabs and browser instances keep going on their own.

This has been desperately needed in browsers for years. Most people keep at least one, and often several browser instances open at all times so it's quite a nuisance when some silly plugin brings the whole show down. Firefox has made some kludges to handle this, like the ability to restore a session after a crash, and they probably would have moved in this direction eventually.

Chrome also has a new, streamlined Javascript engine, v8. This, along with the robustness that a multi-process browser brings, makes Chrome an excellent platform for the web applications (like Gmail and Google Docs).

That's what Chrome is really about. If they can get it installed widely, they (and anyone else) can make an end run around Microsoft's OS monopoly. The clincher is an open document standard, which is why Microsoft has been fighting the Open Document standard so viciously, and trying to force their proprietary format through the ISO process. Without that, Microsoft can hold on to their OS monopoly by withholding Office from any serious competitors.

There are a few disappointments with Chrome. There's no ad filtering, and as yet no extension mechanism to implement it (though they've promised to rectify the latter).

Google is, of course, not going to be terribly keen about people stripping advertisements from the web, but they also will have to face the fact that it's necessary. I realize they have to walk a fine line with this, but they're in a great position to help mediate between the extremes of filtering absolutely everything (as many Firefox users do with Adblock Plus and EasyList/Element) and the downright offensive lengths some advertisers will go to to annoy the crap out of people.

Google could start a clearing house for web advertising with a voluntary code of conduct requiring advertisers to tag their ads appropriately for filtering by the browser. Public key encryption could be used to verify that an ad is released by a member in good standing. Users who don't want to see animated ads, ads with sound, ads for porn or whatever could filter those and let less obnoxious advertising through to support the sites they visit. There could even be an automatic negotiation between the browser and ad server. A user who may be willing to accept text ads could be presented with those instead of being forced to block all ads to keep the annoying ones out.

What I've been reading

Here are some amazingly haunting long exposure shots of crowds faded into a ghostly fog.

code_swarm is a project that makes some really neat visualizations created from the history available in source code repositories. Processing, the library used to create the tool that made these videos looks like it might be fun to play with.
