After leaping many hurdles, teach4kids.com will be the hosting site for future technology4kids editions. The 1st and 2nd Editions will remain on their current servers only future editions will be affected by the new hosting arrangement.


The Teach4Kids site is being closed down for lack of participation. We will continue to update our community service sites and we will be offering publications for smart phones and tablets in the near future.

Another hurdle . . . What are the security-related implications of SOPA?




One big one is how it interacts with the domain name system and a set of security improvements to it known as DNSSEC.The idea of DNSSEC is to promote end-to-end encryption of domain names, meaning there's no break in the chain between, say, Wellsfargo.com and its customer. Requiring Internet providers to redirect allegedly piratical domain names to, say, the FBI's servers isn't compatible with DNSSEC.Rep. Dan Lungren, who heads the Homeland Security subcommittee on cybersecurity,
has said that an "unintended consequence" of SOPA would be to "undercut" the effort his panel has been making to promote DNSSEC.The Sandia National Laboratories, part of the U.S. Department of Energy, has also raised concerns about SOPA, saying it is "unlikely to be effective" and will "negatively impact U.S. and global cybersecurity and Internet functionality." And Stewart Baker, the former policy chief at the Department of Homeland Security who's now in private practice, warned in an op-ed that SOPA "runs directly counter" to the House's own cybersecurity efforts. An analysis (PDF) of Protect IP prepared by five Internet researchers this spring lists potential security problems. Among them: it's "incompatible" with DNSSEC, innocent Web sites will be swept in as "collateral damage," and the blacklist can be bypassed by using the numeric Internet address of a Web site. The address for CNET.com, for instance, is currently 64.30.224.118.
