Just an explanation/apology, I did read the submission guidelines ( http://ycombinator.com/newsguidelines.html ) before posting this. I didn't see a blanket anti-promotion policy. I obviously have a big vested i

Yeah it is interesting. My read is he is saying that any de-stabalizing change isn't worth it at this point (even if it is a net improvement). Yet we all envision Knuth as an optimizer and tinkerer. Of course few people have experien

Obviously I (and most people here) are not privy to the the truth (and you can't find the truth by sharing opinions or taking opposition to opinions). But he hasn't been "silent." He pled guilty to related charges, he

You are right- it is back. Perhaps it scrolled off (instead of being buried. i.e. I was probably wrong- sorry).

Yet he writes against this in the article: "Any object of nontrivial complexity is non-optimum, in the sense that it can be improved in some way (while still remaining non-optimum); therefore there’s always a rea- son to change anythin

And this thread is now deleted/blocked/banned/hidden. (not by me, I am not part of ycombinator/HN org). edit: It seems to be back now. It probably scrolled of instead of being flagged/buried. So I was wrong, sorry

I agree with you: HN time-outs and failures (which also occur on reading) are an unnecessary pain. This is one reason you should never write into a web text box (a rule I also fail to adhere to). But really even "modern application g

Always good to hear good calm advice from somebody I know and respect, Will. I admit I make tons of mistakes (and also would never start anything if I always "thought it through"). But I still really don't like what the ori

Down vote me on this, but here is my honest opinion (that may actually help others) phrased as a question. Why would you as a hobby run a payment site linking credit cards and checking accounts when you appear to not have done any research

I am guessing the NYC/DC train corridor is nicer than what we have on the west coast. I was looking into a holiday ride through silver country here, and the reviews unfortunately came back a big "heck no."

How about making the paying Amtrak experience nice instead of making a Potemkin ride? (see: http://reason.com/archives/2005/12/01/amtrak-sucks )

In my opinion there is a difference. You can build a classifier that says "does the person have a 30% chance of defaulting this year." And you can in aggregate estimate the accuracy of such a classifier. However, for an individu
