Being a small ISP, that's a good solution, but you run into implementation problems. I am dealing with a migration to a usage based billing. And it is difficult to extract that data from the DSLAMS and then turn it into meaningful data that our billing system can handle. Plus you need to provide the user access to that data so they can check to see what their usage is at any given point. It's expensive to implement, and it must be custom written for your specific DSL DSLAMS and billing system. Ours currently can't tally usage.. So we'd have to write our own scripts to do that. What if there is an error in them? What if it breaks in 3 months after I leave the company or get hit by a bus? What if a customer refutes his usage, can you back up your data's integrity against his data? There are tons of expensive problems we're running into going usage based :(

You couldn't afford to buy 8MB of dedicated Internet content. I pay upwards of several thousands a month for dedicated 25Mbit of service for providing content to our small locations. Actual dedicated Internet content is very expensive. The only reason you can afford DSL is because the cost of your circuit is offset by overselling the uplink assuming that not all people will be using 100% of your link 100% of the time. If you look at the ToS of your provider, they will always state speeds "up to" what you buy. That's because it's oversold.

I an the senior network tech for a small ISP. We manage 10 sites. Some with as many as 2000 customers, some with as few as 40. All it takes is one abusive user to ruin the internet experience for all people in a site. We also face the problem of satellite delivery for our network content since most of our locations are unaccessible via terrestrial means. So bandwidth is not only limited, but very, very expensive. We also limit our DSL and cable modem services down to 256k because of the cost of delivery. We have implemented Packeteer Packetshapers and have filtered out all P2P traffic except bittorrent. And we have torrent traffic limited to a max rate of 10% of the pipe to an area. This is especially important to satellite as most p2p software streams without regard to satellite latency and bandwidth constraints and floods the link causing service outages for our sites. We have only had a few complaints over the years. And those folks we refer back to our ToS as we lay out the p2p restrictions in there. We have had to take the approach to penalize the few for the sake of the many. We would rather have one or two pissed off customers then have 1000.. We also utilize monitoring software to track overall bandwidth utilization of each client to find abusive users (users that peg their bandwidth 100% of the time) and penalize them if it is causing detrimental service to our other customers. We have learned over the years that you can never had enough bandwidth. The more you provide, the more the users utilize. And you will always have a few that push the envelope.

Submission + - Brain cancer treated with electrical field

amigoro writes: A device that specifically targets rapidly growing cancer cells with intermediate frequency electrical fields — called Tumor-Treating Fields (TTFields) — doubled the survival rates of patients with brain cancer, according to a Proceedings of the National Academy of Sciences (PNAS) journal article. The device uses electrical fields to disrupt tumor growth by interfering with cell division of cancerous cells, causing them to stop proliferating and die off instead of dividing and growing. Healthy brain cells rarely divide and have different electrical properties than cancerous brain cells. This allows the device to target cancer cells without affecting the healthy cells. The only device related side effect seen was a mild to moderate contact dermatitis beneath the field delivering electrodes, which responded well to the application of topical cream and periodic electrode relocation.
