Comment Re:Why not block other things by default, too? (Score 1) 310

If I don't specifically ask for "slashdot.com" in my web browser, I don't get it. I guess my ISP must be blocking it. But fortunately, once I "ask" for it, I get it, usually within seconds.

Unfortunately, slashdot.org sometimes stays blocked for a few more seconds. Must be that "slashdot effect" I keep hearing about.

Block the whole internet by default. Customers have to submit a list of checkmarks letting the ISP know what they would like to have unblocked.

I think my ISP does that already.

Comment Re:National Traffic System (Score 1) 205

What do you mean by RTS/CTS in NTS?

I'm guessing he means the handshake protocols where the sender asks the receiver if he's ready to receive, and doesn't send until he gets confirmation.

NTS also has some rudimentary error-detection/correction built in:

The sender will tell the receiver how many words are in the message. If the receiver does't get the exact number of words or if he has any other reason to think the message wasn't properly received, he will notify the sender and they will try again. If the word count matches and the receiver doesn't believe there are any errors, he will tell the sender that the message was received.

If the sender does NOT receive that final confirmation, he will assume the message was not sent and will try sending it again either right then or later.

with that logic the blind have been reading digital books for ages

So have regular people, albeit with a "base" big enough to hold alphanumeric characters plus symbols (about 60- or 70-something for most English text).

The blind have been reading binary (raised dot/no raised dot) books for ages.

Does the fact that it is binary confer digital status automatically?

In this case, yes.

I assume you are talking about Morse code, which consists of "current off" and "current on" states grouped into dits ("dot"), dahs ("dashes," 3 times the length of a dit), inter-dit/dah spacing (period of no current, same length as a dit), inter-"letter" spacing (3 times the length of a dit), and inter-word spacing (7 times the length of a dit).
