Are they going to drop into every customers home a router capable of 10Gbps of throughput? LOL. That would be expensive.

Not only the 10GbE switches are expensive ($100-200 per port) but the network cards are too. Making them work in a regular PC is a nightmare, most motherboards bus-fault and bluescreen / kernel panic in minutes.

They can use a great encryption algorithm, but if they continue to not authenticate the basestation, as per 2G specs, then it doesn't really help. It wasn't until LTE that this finally started happening.

This problem can be solved at the Mobile Station or SIM by refusing to register or call over a network that does not support at least UMTS authentication of the network and replay protection or that does not activate encryption. This would break connections to 2G networks whose MSC was not updated to support UMTS authentication but it could be implemented as an user option.

A Look At the Firepick Delta Circuit Board Assembler (Video) 43

Posted by Roblimo
from the components-get-tinier-every-year dept.
From the Firepick website: 'We are developing a really cool robotic machine that is capable of assembling electronic circuit boards (it also 3D prints, and does some other stuff!). It uses a vacuum nozzle to pick really tiny resistors and computer chips up, and place them down very carefully on a printed circuit board.' There are lots of companies here and in China that will happily place and solder components on your printed circuit board, but hardly any that will do a one-off prototype or a small quantity. And the components have gotten small enough that this is really a job for a robot (or at least a Waldo), not human fingers. || There are obviously other devices on the market that do this, but Firepick Delta creator Neil Jansen says they are far too expensive for small companies, let alone individual makers.

The Firepick Delta Hackaday page talks about a $300 price for this machine. That may be too optimistic, but even if it ends up costing two or three times that amount, that's still a huge step forward for small-time inventors and custom manufacturers who need to populate just a few circuit boards, not thousands. They have a Haxlr8r pitch video, and have been noticed by TechCrunch, 3DPrintBoard.com, and Adafruit, just to name a few. Kickstarter? Not yet. Maybe next year. Open source? Totally, complete with GitHub repository. And they were at OSCON 2014, which is where Timothy found them. (Alternate Video Link)

Comment: Voice and data are separated (Score 1) 126

by TuringCheck (#47082191) Attached to: US Wireless Carriers Shifting To Voice Over LTE
VoLTE IMS voice uses a dedicated low latency guaranteed bearer for the RTP packets. Traffic on this bearer is charged separately and is not routable to regular Internet.
The SIP signaling also uses a dedicated AP that cannot be used for anything else. Traffic is only allowed towards P-CSCF.
All the IMS client, Quality of Service and dedicated bearers are implemented in the baseband chip (Qualcom dominates that market) and is off-limits to the operating system of the phone, even to root.

3 Former Astronauts: Earth-Asteroid Collisions Are a Real But Preventable Danger 71

Posted by timothy
from the asteroid-survival-movies-are-great dept.
Three former astronauts — Ed Lu, Tom Jones, and Bill Anders — say that reassuring figures about the rarity of asteroid collisions with Earth are perhaps too reassuring. The B612 Foundation, of which Lu is a director, has been established to draw public awareness to the risks of a large asteroid hitting a population center -- which these three men say is a far more serious public danger than has been acknowledged by NASA and other agencies. And beyond awareness, the Foundation's immediate goal is to raise money to " design and build an asteroid-finding space telescope and launch it by 2017," and then, Armageddon-style, to follow that up with technology to divert any asteroids whose path would threaten earth.

is there a recoil on rail guns? or is this a joke?

The recoil is lower than a conventiomal chemical gun for the same projectile and speed because no gas is accelerated with the projectile.

However, rail guns tend to be immensely heavy beasts to withstand recoil and transversal electromagnetic forces.
