Yes this is a huge tragedy and this may not be the _best_ forum for BPL. HOWEVER, do yourself a favor and educate yourself on what BPL will do on effective HF communications.

Listen for emergency traffic for the Maritime Mobile NET on 14.300 Mhz.
Get frustrated on how far you have to drive to avoid the interference.
The Maritime Mobile Net has been instrumental in accepting and relaying emergency traffic for ships in the affected tsunami area and it is just one of many services Amateur Radio is able to provide. Next time a disaster hits your area you should read what services your local ARES/RACES (www.arrl.org) chapter volunteered for.
During the hurricanes this year the ARES/RACES chapters of Central Florida were instrumental in providing communications between all of the shelters that had been opened up. We were able to pass messages to the Emergency Operations Center even when the police band could not be used.

I'd like to see the Wi-Fi shootout goal to be coverage area. This could also benefit MeshNets as well.
Although, I would be interested to know the antenna gain and RF power they were using this years 55mi link. For most of us, unamplified is about 35mW give or take, but you can also get 200mW cards which will get you a whole lot more distance 'unamplified' than with the 35mW cards.
Then to get Effective Radiated Power (ERP) you need to know the antenna gain. Every 3 db of gain will double your power. 100mw from your transmitter into a 3db antenna will give you 200mw output, assuming you have 0db cable loss.
So if they were feeding 200mW into a 23db (example figure) dish they would have a focused beam putting out 200mW*2^(23/3) which is 40W. And if you're feeding it with a 35mW card, its still 7W.
Since when is expensive jewelry taken through a self checkout line? I hardly see jewelry stores adopting self-checkout counters. There is a reason why they keep stuff under lock and key, and then there is the lady in high heels who wears too much make-up and jewelry who encourages you to buy the more expensive piece.
"This book was supposed to be about entertainment - the battle over control of digital music, text, and video... But as I researched this new project, the world shifted beneath my feet... My concerns moved to the regulation and control of all sorts of information, much of it cultural, much of it political."

I keep meaning to test the iLBC codec over a GPRS connection (T-Mobile T-zones is only $9.99/mo for unlimited internet access). The end idea would be to make a VoIP call using iLBC to an Asterisk server at home. Which would then forward the call to Vonage. iLBC is <15kbps, so 56k gprs connection should be adequate... i just don't know about the latency..
You're thinking of gamma and X rays. We're talking about reg'lar old radio waves. Radio waves live on the other end of the electromagnetic spectrum. Radio waves are non-ionizing (i.e. they don't hurt your DNA). An EMP can be almost entirely dissipated by a well grounded metal shield. Physics. It's not just for kids!
Who said anything about hurting your dna? Tell you what. I'll let you stand infront of my 23db 13cm dish while I key the radio. Let me know if that gives you a warm fuzzy feeling inside. RF works great to cook flesh.
This is an image I received recently from Dell when my PowerVault 132T went on hiatus. Device was completely non-responsive and showed "Uknown drive error" which to me reads "ball is in your court" with respects to dell, since power cycling did nothing. This image is what the gold support rep sent me as an official procedure:
paperclip.
I mean yeah... the paper clip is part of my toolkit, but a picture of it from this particular source?
Nmap is still GPL. They didn't modify it. The debian guideline states that the license cannot discriminate against persons or groups -- the GPL is compatible w/ this statement / 'social rule' for debian. Nmap just invoked the part of the GPL that lets them revoke the license from an individual or group. Nmap is discriminating, not the GPL.

Leave onStar so we can avoid pulling you over and automatically deduct the speeding ticket fine from your checking account or credit card. Anyone remember Seaquest DSV?
From personal experience of having loved ones abroad -- more specifically on islands in the caribbean that charge in excess of $0.50/min for long distance to the island(up to $1/min for VoIP providers) and $1-$3/min from the island -- I have discovered that using the Asterisk PBX [asteriskpbx.org] with an IP Phone cuts down on my long distance bill dramatically.
Many of these islands offer 256/128kbps dsl service for under $100/month. Add a DSL line on your side with asterisk and you're in business. The savings I've gained by free long distance has paid for the extra hardware I purchased -- FXO & FXS line cards. Asterisk does more than support PC-to-PC calls. It supports a range of telephony hardware that enables you to create your full-featured PBX or in my case: VoIP->PSTN gateway.
Whenever I travel in or out of the country I can usually find complementory internet connection somewhere (or pay for one for $10-30/day) and call people to my hearts content. To them, it would appear as if I were calling from my home phone... because I am.
Its really the Anti-Vonage setup, but it serves my purpose. If I need a long distance voip provider I can just add it to the dialplan/configuration.

I saw nothing in their website with regards to IP->POTS or POTS->IP transversal. Therefore I don't see where I can make free phone calls all over the world in the traditional sense. "Hey, I wanna call you, but you need to have a computer with broadband and this computer -- oh, and I can't call you from my phone; I must use a computer too."
So isn't this just a hyped up distributed/proxied Voice-chat program? Doesn't Yahoo and ICQ (VIRC and others too) provide similar functionality?
I think I'll stick with Asterisk PBX and use hardware from Digium. Yes, it requires additional hardware for POTS/PSTN stuff, but you can do almost anything you want with it. SIP clients can make phone calls very well through firewalls (receiving takes an extra step or two) and many of the free clients give you a choice of what codecs to use (GSM, iLBC, G711u, G711a). Another option you get with asterisk is using their IAX protocol which is more forgiving around firewalls IMHO.
The board was recruited because of how heavily they were already networked. These connections help SAIC greatly in its winnings of contracts, be it military, gub'ment, or commercial.
SAIC _does_ have a large number of contracts in government and military, but only 1/7th of the employees in the company work on material that requires a security clearance. That leaves over 85% of the company doing other things.
Don't judge a company because of its board of directors, or because of their previous title. SAIC does good work and it is done by good people.
My ethics training at SAIC (something all us employees go through every two years) said that we're not supposed to do stuff like that. Then again, the pens and pencils they were giving out at the seminar (at a SAIC building) had labels from a Hotel in another city on them.
I guess stealing pens and pencils is fine, but back doors are bad.
Yes, but SAIC will atleast verify that there won't be any so-called hanging chads, or so we hope. It'll be a 1 or a 0. Now... if you can enter just the right answers to cause a buffer overflow and pop in some executable code, you could make whoever you want to win.

As an amateur radio operator I enjoy having the HF bands in a semi-useable state. BPL is a bad idea in my humble opinion.

DoD will never let something like that fly in any of its facilities. Microsoft will have to provide a way to disable that service.
I'm sure if MS does go that route then there will be a lengthy section in the Windows STIGs to destroy it.
