Comment Wire Tapping in Two Party States (Score 1) 140

http://www.rcfp.org/can-we-tape

So with wire tapping laws, some states require all parties involved to give concent to the recording. These are 2 party states. All other states are 1 party states, which means only one person involved in the recording has to give concent.

Now if they are recording incoming information within a 2 party state, the sender of the SMS message has to give concent that the message can be recorded. This is reguardless of the contract of the owner of the phone has. Ultimately, anyone who has ever sent a message to one of these phones in a 2 party state could possible sue.

The system is seperate from the cable company system. You can actually grab two of these and run a single coax cable between them and they will work. We once used two like this before because they actually have a longer cable distance than cat5 and we had to run a longer cable than 100m. An additional note is that extremely short cables will not work, 6 inches and below are too short anywhere in the coax. It will cause reflection and decrease the single strength. Also, you can have multiple splits in the coax network, and it will still work. Usually you put a Point of Entry (POE) filter at the root of the coax system so it does not leak outside your house.

This is what Comcast and Verison use as their backbone for multi-room DVR. It will give you the most reliable connection. You can have multiple endpoints, and you have have multiple MoCA networks over the same Coax lines. They use QAM channels over 1GHZ that will not interfer with your cable TV. And they will auto detect existing networks, either join them or create their own based on security settings. Additionally you can hang a switch off an endpoint to have more ports at a location.

You don't have to use wireless if you don't want too. You said you have coax. There is IP over coax that has a backbone of 100-250MB/s called MoCA. Just ebay it, they have routers and endpoints. You don't need a MoCA router, just endpoints. They work as a switch where each port can be located off a coax line, and the backbone is the coax network.

Submission + - New 1W Green Handheld Laser (wickedlasers.com)

whitedsepdivine writes: After having there customers wait 6 months for their Spyder III Arctic 1W blue laser, Wicked Laser releases there Sypder III Krypton green laser. This laser comes in 300mW, 500mW and 1000mW versions, at a price of $1 per mW. With claims that humans will perceive green light up to 2000 times brighter than blue. It comes with other improvements such as Tesla Cooling, and a second version of the Smart Switch. There is currently no disclaimer that this is not a Light Saber on their site, so we can only assume that this version is.

Submission + - Laser self defense

whitedsepdivine writes: So my neighbor is shining two 100-200mW green lasers into my house, and she actually got it in my eye. That shit still hurts. I told them to stop and they just continue. This has been going on for a couple of months. I have an 1W Class 4 laser, and I am being pushed to use it in self defense. If someone is shooting a gun at you, you can shoot back; someone punches you, you can punch back; someone pulls a knife on you; you can stab them back, all in self defense. Now someone pulls a little 22 on you and you pull out a Barrett 50 BMG is that the same? Cause I feel like this is the gap between our lasers.

Comment Transforming Solar power into propellant (Score 1) 201

If somehow they could use solar power to create energy usable by the ship. First you wouldn't need to re-fill the station ever. Second, you could have less weight on the ship to not have such transforming components. I would image these stations will be the most rarely visited gas stations created by man. So you would have a long time between visits to transform the solar power into another energy source.

Comment 4 modems does not equal 4 times the speed! (Score 0) 115

Ok, the article stated by combining 4 modems will get you 4 times the speed. Except that would require each modem to be on it's own 4 channel bonded system. As we all know cable single is distributed, so each connection isn't dedicated. They would require 4 docis3 head ends that connected to each modem. Currently there isn't funding in most areas to get 1 docis3 head end. Additionally this cuts into your cable channel lineup. Each digital stream is 6mhz wide and have 2mhz on each side to reduce channel interference. that means this will take around 160mhz (8mhz * (4 down stream + 1 up stream)) of your cable stream. Currently they are only able to use something around 10mhz to 1000mhz so that means you will only have 840mhz left for channels. If you think everyone is getting a dedicated 1.5Gbps that is a ways off.
