To me it seems crazy to spend so much on a 3-D printing costs when there are cheaper, easier solutions. The umbilical chord clamp: Teach people they can just leave the baby attached to the placenta till it dries out, or tie it of with string or anything else they have at hand before cutting the chord.

Usually at some point the server needs to be able decrypt the data so it can be displayed to a user, so the key needs to be handy. So if you have the key and data on the same sever it's of little security value.

If you want to have this data in some kind of database, there is a good chance you want to be able to search and index this data. Possible to index and pre-sort encrypted data without giving away the content?

Yes, maybe encrypt some sensitive parts, but encrypting all customer data is counter productive.

DSL uses ATM AAL5 http://en.wikipedia.org/wiki/ATM_Adaptation_Layer_5 So you have ATM overhead, AAL5 overhead. So you have 40 bytes of payload, which then contain overhead from higher layers Then if your DSL is using PPPoE you have Ethernet overhead, and PPP overhead. Then you have IP and TCP or UDP overhead.

If WhatsApp doesn't add more security, my prediction, is we will start to see WhatsApp spam. If you know phone number and it's IEMI you can fake the sender using the WhatsApp protocol. All it will take now is someone to acquire a database of IEMI's and the phone numbers before the spam can start flowing.

Publish the patches on the project mailing list, forum, or on your own website or blog. The most important thing is to get the patches out there. That will open it up to peer review and discussion. From there you have the possibility of linux distros picking up the patch and using it. Eventually the project may pick up your patches. A fork would be a last resort.

Activision CEO Warns Sony That the PS3 Needs a Price Cut 149

Posted by Soulskill from the take-the-hint-sony dept.
Bobby Kotick, President and CEO of Activision, one of the largest game companies in the world, has come out with a none-too-subtle warning to Sony that they need to seriously consider a price drop on the Playstation 3. Rumors have been circulating for months that such a drop was forthcoming, but Sony has staunchly denied that they had any plans to drop prices, Kotick said, "The PlayStation 3 is losing a bit of momentum and they don't make it easy for me to support the platform. It's expensive to develop for the console, and the Wii and the Xbox are just selling better. ... They have to cut the price, because if they don't, the attach rates [the number of games each console owner buys] are likely to slow. If we are being realistic, we might have to stop supporting Sony." While it's unlikely that Activision would follow through with such a threat, it definitely adds to the pressure Sony is feeling to lower the PS3's price. Sony issued a brief response which said nothing of consequence.
