It’s been a year since the GPLv3 was introduced to the open source world — so how’s it doing? That’s the subject of two surveys currently being conducted to track open source license usage and conversion.

The first survey, conducted by Black Duck Software, shows the GPLv3 coming it at No. 7 out of the top 20 open source licenses used amongst projects polled.

Not surprisingly, the GPLv2 filled the top slot by a gigantic margin — 57.81% — while the GPLv3 had a 1.82% share.

That’s still not too bad for a license that was only introduced a year ago; the same survey puts the Apache License at 2.77% and the Mozilla Public License at 1.29%.

The second survey, courtesy of Palamida, also features some detailed quotes from various software outfits about GPLv3 adoption.

Some fairly famous names are in that list — SugarCRM’s Community Edition and Samba, for instance, have adopted Version 3, although there are still plenty of big names sticking with what they have.

I’m not terribly surprised by this, since I didn’t figure the GPLv3 was going to be an automatic upgrade for most people.

One thing that would be useful to know, although admittedly not the easiest thing to harvest, is activity statistics about the projects in question — maybe by using the activity stats from Sourceforge if the project’s hosted there.

This would give us some idea of the degree of usage or participation for each project. It’s one thing to say “2,800 open source projects use the GPLv3,” but what percentage of those 2,800 projects are, say, part of the top 100 or even 500 projects at Sourceforge?

Finally, a quick and admittedly unscientific glance at the lists of projects in both surveys shows a healthy mix of project types — a little of everything under the sun, from what I can tell.

It’ll be interesting to see where things stand in another year — or even by the end of this one.

Roughly 59% of Internet users use the latest, more secure Web browsers, according to an examination of what version Web browser, down to the patch level, people are using.

That means about 576 million Web surfers leave themselves vulnerable to attack. You might just (not) be surprised by who doesn’t patch.

The study, published today, was conducted by the Swiss Federal Institute of Technology, Google, and IBM Internet Security Systems.

The researchers found that no matter how quickly browser and plug-in vendors create patches to fill security holes, it could be months before a large segment of the Internet population will apply those patches.

While I wasn’t surprised to see 83.3% of Firefox users having applied the most recent patches, the same can’t be said for Opera users, because only 56.1% of those users keep their browser up to date.

One would think that both Firefox and Opera users would be more technically savvy than the average user, thereby more prone to patch. Unlike Internet Explorer users, where less than half, at 47.6%, bother to apply the most recent software updates.

The study examined search and Web application log data from Google to ascertain what version of browsers, including patch levels, are used.

For Internet Explorer, the researchers culled data from Danish security firm Secunia’s Personal Software Inspector.
