Why should users care? How many "users" are aware of IP addresses, or view them as anything but a string of meaningless digits? The "complexity" of IPv6 falls entirely on sysadmins and on those who implement IPv6 stacks, that is on experts. It's possible some users will have a home network on the 192.168.x.x IPv4 range connected via a NAT to the IPv6 internet, but this choice will be made for them by the people who write NAT software: home users universally use first-come-first-served DHCP to assign addresses on their home network so they never see even the local IP addresses. I like to remotely SSH to my home computer, so I note the IP address assigned to my NAT by the ISP, but a typical user can't pull that off. I also like to have fixed IP addresses inside the home network so I can reliably use SSH between the machines. You might be diong the same. But the average user can't and doesn't feel the need to.

Mozilla capitulating on the tag has serious implications for web standards. By including patent-encumbered code in the browser they take the rug from under those in the www foundation that argue for free web standards. Yes, some websites wanted to use H.264 for video encoding, but Mozilla shouldn't have abetted them.

Post-prohibition most states regimented the alcholic beverage distribution chain into a three-tier system: producers, distributors, and retailers. As you can see this is even worse than with cars. For example, vinyards often cannot sell directly to the public, and they can't sell directly to pubs or wine stores. The middlemen must be paid ...

For wide adoption there needs to be a full market around electric vehicles: opportunities to build charging stations, sell home charging equipment and so on. Gas stations are possible since practically all cars use the same fuel, but also because they have very similar intake openings so that the pump can stop by itself.

Tesla by itself is too small to set standards, so this is good news. It also shows how disclaim in patents helps: the benefit from a greater and more active market exceeds the payoffs from discouraging competition.

A few years ago I switched from tvtwm to fvwm and I'm very happy. One year being forced to endure unchangeable defaults chosen by Apple engineers (which are no doubt very good for most of their customers) further cemented my preference. I still don't understand why focus policy or keyboard bindings are the business of the window manager designer.

Taxpayers should not be paying for someone's pet cause ... Proper action would be to mandate the government to use the best software for the task at hand ... Let the technical merits decide.

I'm sorry, but while technical merits should be paramount, they are not the only consideration. Public contracting is not an exact science, and it is entirely appropriate to have non-technical considerations tip the scales in close cases. So while Free Software should not be mandatory, legislating a preference for it makes perfect sense.

Furthermore, there are considerations beyond the needs of a specific project and tender. Free Software has an externality: when the government (as a customer) requests modifications and improvements (and pays for them to be created), everyone benefits. For example, when my university has Blackboard Inc fix a bug (or improve the software) only Blackboard captures the value (when they sell their software to the next customre). If we were using Moodle, every other Moodle user would automatically benefit. Had we opted for Moodle, we'd also benefit from fixes made by other universities.

Squaring key lengths would be entirely impractical. That said, the improvements only apply to a case of discrete log which isn't actually in use. Cryptographic algorithms generally depend on hardness of discrete log mod p (p a large prime), not in the field with p^k (p fixed, k large).

Yes; the preprint was posted to arXiv when the research was completed. Obviously Science Magazine (the source for the slashdot posting) prefers to write about results when the journal article comes out later, because otherwise the magazine would to check the preprints for correctness on its own, which it can't be expected to do.

Stupidity, like virtue, is its own reward.
