Submission + - What all can I spell in a mac address?

mwilliamson writes: I guess I'm bored tonight. Someone on facebook started talking about seeing words spelled out in mac addresses, so I got to thinking how many possible English words could be embedded in a mac address.

Creatively querying aspell, I came up with 346 words I also allowed 0 and 1 because, well, they look like o and l.

The following will give the complete list: /usr/bin/strings /usr/lib/aspell-0.60... |... grep -v -i [g-k] | grep -v -i [m-n] | grep -v -i [p-z] | grep -v '*' | tr [A-Z] [a-z] | uniq

More interesting ones (to me anyway) include:
offloaded, accolade, oddball, bobble, baffled, beefed, blob, boldfaced, fable, facade, faded, cocoa, coal, coldblooded, deaf, flooded, loco, lead, and doodad.

Comment cleartext unencrypted nation-wide traffic (Score 4, Insightful) 311

So what is the big deal? This data was sent out unencrypted from many transmitters all across the nation. It would have been (and still is) very easy to intercept. There is no data security. Those considering it a secure medium have simply been mislead. Congress, as a whole, is rather ignorant of these technical concepts. There are programs that use a soundcard for data capture, but for best results make sure and use the receiver's discriminator output, not the filtered audio out. Google for "POCSAG and FLEX decoding" for all the goodies and software you need to do your own intercepts. -Michael

Uh, no. Range is not a function of signal power. It more is a function of the overall signal/noise ratio and the sensitivity of the receiver. This includes noise introduced in the transmitter, natural/other noise, and noise introduced in the receiver. An antenna system with gain can both concentrate and attenuate signals, depending on the directivity and where its pointed.

BTW, I got over 1400 miles out of a little 0.3 watt ham signal, but thats no where near as impressive as Earth still being able to receive signals from Voyager 1 and 2 nearly 10 billion miles away. That's impressive.


Comment SSN is an IDENTIFIER, not AUTHENTICATOR (Score 2, Interesting) 268

Anybody or organization using an SSN as both an identifier and a form of authentication is stupid, irresponsible and should be held accountable 100% for breach of whatever resource they control. The problem is in the "shared secret" type use of a damn 9-digit number, with a few of the digits already known based on state of birth.

Want a list of ssn's for every state? Here's all of them. Have fun.


Comment Lithium, a limited natural resource? (Score 2, Interesting) 281

It seems like this is the holy grail for electric vehicles, and we can finally stop burning dinosaur juice in our little bitty engines and realize the economies of scale of burning dinosaur farts in really big and efficient prime movers. This is all well and good, but how plentiful is lithium, and can it be recycled easily (I suspect yes)? -Michael
