Is 3D Printing the Future of Disaster Relief?

KarlH420 economics (88 comments)

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.

Calif. Attorney General: We Need To Crack Down On Companies That Don't Encrypt

KarlH420 technical challenges (127 comments)

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.

Ask Slashdot: AT&T's Data Usage Definition Proprietary?

KarlH420 Re:Headers (562 comments)

If you add ATM and AAL5 overhead that DSL has http://en.wikipedia.org/wiki/ATM_Adaptation_Layer_5 Then 20% sounds reasonable. 30% sounds reasonable if they are encapsulating traffic with PPPoE and a lot of your packets are not at the max MTU.

Ask Slashdot: AT&T's Data Usage Definition Proprietary?

KarlH420 Re:DSL ATM overhead (562 comments)

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.

WhatsApp Threatens Developers of PC Gateway With Legal Action

KarlH420 WhatsAPP spam comming (27 comments)

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.

Contributing To a Project With a Reclusive Maintainer?

KarlH420 Publish patches (162 comments)

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.

Testing IT Professionals On Job Interviews?

KarlH420 I like giving test.. (1057 comments)

I've hired a few people in IT. Usually you get 100 resumes for a position, then I select the 10-20 CV's/Resumes I like the best. Then I give those 10-20 people a test of basic concepts. You can get rid of the people then that have no f***'ing clue and not waste you time on them. If they pass the test they get an interview.

Too many people have read an article on /. about some technology, or tried something out for day then put it on their CV like they are an expert.

Some people say that's what on the job training is for, but when I hire somebody, I want them to come in and hit the ground running.
