Comment Re:TCP regulating congestion (Score 1) 187

TCP does effectively limit throughput by means of the Sliding Window Protocol. Packet loss will decrease the size of the sliding window, but on a congested network, the window will be slow to increase. What TCP doesn't offer is different Quality of Service. uTP attempts to run TCP at a lower priority than existing TCP traffic. Allowing Skype or YouTube to run at a higher priority is advantageous to the users of those services.

Many campgrounds will have WiFi of some sort or the other. If they don't, you're probably staying in an area which isn't going to have 3G service, and may only be able to get a 1 bar signal on Edge.
I'd suggest building a cantenna, as often campgrounds have a single Linksys router in the lodge, and if your parked more than 50 ft away you'll have a hard time connecting. http://en.wikipedia.org/wiki/Cantenna

Comment Air Traffic Control (Score 2, Interesting) 179

Having setup an ATC radar in Palm Springs, I can attest that the wind farms add a lot of noise to ATC radar systems as well as weather systems. Noise on the radar screen makes ATC more difficult, and increases the risk of accidents. The wind mills in Palm Springs are the small blade, fast moving type which birds like to fly into. I think the newer, larger wind farms are less of an issue for ATC radar. The slower moving blades can be filtered out. If they could build the windmills with flat edges, or use radar absorbing materials, they would become invisible to the radar.

Comment Any noun works well as a hash (Score 1) 688

Users, tech support, and admins can easily remember names and lookup details in a spreadsheet or db. At the prior bank, workstations had names like 'piglet'. When looking at DB locks, the first few times I had to look up the user, but subsequently I quickly memorized the frequent workstation names I came across. Where I work now, they use an alphanumeric identifier. I can't even remember my own workstation name. Workstations already have unique id's like a MAC address and service tag - the machine name doesn't need to be hard to memorize like these are.

I fully agree. With other EPA ratings, they compare similar sized appliances with each other. Your dorm fridge rating won't be compared to a full size fridge which could be quite a bit more efficient. The customer has probably figured out what size server they want to buy before they look at the energy ratings. If you've decided on the specs of your server, you can look at servers from several different companies who can provide you with similar hardware. At that point, if one has a better Energy Star rating that the others, it might influence your purchasing decisions.

Comment The switch from DC to AC (Score 2, Interesting) 340

I suspect the switch to IPv6 will take about as long as the switch from DC to AC electricity. IPv4 is so ingrained in hardware and software that it will take decades after the last IPv4 only hardware has been produced for the switch to occur. Additionally, the cost of IPv4 addresses is going to need to rise above the couple of dollars a year it currently is at. http://cityroom.blogs.nytimes.com/2007/11/14/off-goes-the-power-current-started-by-thomas-edison/
