Re: Does anyone use the Vim HJKL cursor keys?

Both arrow keys and HJKL are not very efficient.

There are much better solutions around for navigation and editing text, such as:
- GuiFN
- SpaceFN
- Exend

Keeping your fingers in the home position is best! Also these schemes work in ANY editor, not just vi.

Re: Let's get really esoteric: big-endian or little-endian?

Let's have big endian for everything. It makes sense to have the most significant thing first: Numbers: ...hundreds -> tens -> units (we already do this!) Dates: Let's have: year - month - date (as per ISO 8601) Times: HH:MM:SS (we already do this!) domain names: should really be: uk.co.bbc.www not ...

Re: Rethinking Blue Eyes - A Logic Puzzle

Interestingly it wouldn't foul things up at all. Each islander on ilsand N>n would see n blue eyed islanders arrive and they would be excluded from the counting so N BEP woule leave on day N leaving the new n BEP behind. Unless the n new BEP became bound by the rules of whatever island they landed ...

Re: Rethinking Blue Eyes - A Logic Puzzle

Suppose there are actually 201 separate islands.... Actually, thinking about this a bit more, yes I quite like it also. If you are on an unknown island, and you see 0 blue eyed people. You know you must be on either island 0 or island 1. When the Guru plants the flag it immediately tells you which ...

Re: Rethinking Blue Eyes - A Logic Puzzle

Whee! I’ll jump back into this for some fun times! I still like this explanation: Suppose there are actually 201 separate islands, named “island 0” through “island 200”, where each island N has N blue-eyed people on it. Of course, the people on the islands don’t know which island they are on. One d...

Re: Rethinking Blue Eyes - A Logic Puzzle

i think most people who discuss the puzzle have had that epiphany moment. The gut instinct that some days can be skipped or something is common knowledge because it's deeply recursive is very common. Welcome to this side of the coin. The reasoning process that happens after the announcement (blue e...

Re: Rethinking Blue Eyes - A Logic Puzzle

Bugger! OK, so I started writing a detailed post with everybody's knowledge of everyone else in detail, including all the information that I figured the islanders could incorporate into their models. But then I had an epiphany and realized something rather shocking: What I have been arguing all this...

Re: Rethinking Blue Eyes - A Logic Puzzle

All that is required is that all models to have at least one blue-eyed person in order to make the Guru redundant. I believe I am still waiting for you to tell me on which day I can say something about my eyes in the case that I can see two blue eyes. In my interpretation, the situation is this: As...

Re: Rethinking Blue Eyes - A Logic Puzzle

(By the way, "many" to me means sufficient blue-eyed people to not change the logic. So 4 is fine). No, 4 is not fine. There is no "sufficient" n. It doesn't matter if there's 1000000 or a Graham Number of blue eyed people, the chain still ends at 0. I think you misunderstood wh...

Re: Rethinking Blue Eyes - A Logic Puzzle

Rethink that step by step you are giving someone knowledge that they don't have. You are trying to add knowledge A has into the hypothetical B's knowledge of C without a real reason why B should have that knowledge. A knows that everyone sees at least 2, but A doesn't know whether B knows that. If ...

Re: Rethinking Blue Eyes - A Logic Puzzle

Let's go with your four-person example. Alice, Bob, Charlie, and Diane are on the island. No one knows the color of their own eyes, but each sees that the other three have blue eyes. There's no guru to make any sort of announcement. Each one is thinking about what the others know or don't know. Ali...

Re: Rethinking Blue Eyes - A Logic Puzzle

(By the way, "many" to me means sufficient blue-eyed people to not change the logic. So 4 is fine). So, it seems all the objections to my "Guru provides no new information" argument come down to this iterative reasoning process. And I get what you are saying: I see 99 blue-eyed p...

Re: Rethinking Blue Eyes - A Logic Puzzle

Everyone already knows that there are at least 99-blue eyed people on the island This is incorrect and the crux of the issue: If you see 99-blue eyed people on the island, you don't know if "Everyone already knows that there are at least 99-blue eyed people on the island" or if "Ever...

Re: Rethinking Blue Eyes - A Logic Puzzle

I disagree. Consider the following questions where the count starts when the laws are stated, but you do not get a guru to tell you that there is a person with blue eyes on the island. Question 1: You are on the island, you see 0 persons with blue eyes, do you leave on day 0, or 1, another day, or ...

Suppose that there exists a day where the island, its people, the rules, and their knowledge of the rules all spontaneously come into existence all at once - but the Guru doesn't say anything. Label this day as day 1. There are N blue-eyed people. When do those people leave? You're saying "on ...

Re: Rethinking Blue Eyes - A Logic Puzzle

Ah, the blue-eye puzzle. I first came across this about 20 years ago, and became fascinated - possibly even a little obsessed - by it. I came to the conclusion, which I still hold today, that the statement of the puzzle has a critical flaw, so I wanted to post here to see if anyone agrees. I've read...
