Not necessarily. It is possible that Google incorporates clickstream data too. The problem that Google's little experiment highlighted was: given the utter lack of any other signal, Bing uses the fact that that URL was ranked #1 by Google

the author does not understand the issue even superficially. That, in a nutshell, is it. I don't know why we're spending so much time on this post, as the author has no idea about how search engines work, and what is robots.txt . If he ha

If a page is not crawlable, but listed in the search results based on anchor text (or the URL), then it will not have any snippets. You can show snippets only if you crawl the page itself.

URL discovery is one thing; ranking that discovered URL at number 1 without any other signals is another. I don't think anyone cares that much about how Bing does URL discovery (unless, of course, the URL is supposed to be private and excha

It is. Only domain names are case-insensitive. This document explains how Google handles robots.txt : http://code.google.com/web/controlcrawlindex/docs/robots_txt...

"Control" what? Where's the control for "gravity pulled the apple down" ? It's called an existential proof. If you want to prove that a black swan exists, all you need is 1 example of a black swan.

It just means a crawler cannot retrieve the page; in other words, a crawler cannot GET a URL for whom there's an exclusion pattern in robots.txt .

Does the index include the dictionary too, in your calculation? I'd be interested in seeing this indexing/retrieval program of yours, I hope you release it soon!

I'm missing the point, so I hope the HN community can enlighten me, but: why do you need Cassandra and all that jazz, if you're just incrementing counters? A decent memcached instance on modern hardware can easily push several 100K updates/

Why? The law says that you can buy tickets, and return unused ones. So just buy a bunch, scratch the winning ones, and return the rest. There's no law which says that "if you can figure out how the lottery works, it is illegal". Their recou

My guess is the following. Lets say that the numbers in the game are in the range [1..N]. Lets further assume that there are M slots (or squares where numbers are placed). Suppose M is about 3*N. So, on average, you'd expect each number to

You can't randomly throw numbers around without listing your benchmark code, the config files, etc. Secondly: even though it becomes clear eventually, you should mention up front your relationship with Clustrix. Just because you are a found

Wow, 50K karma in just 785 days? That's almost 64/day, quite a feat. For me, the discussions in the threads are the best part of HN. The submissions are great; but what brings it all together is the discussion.

Repeating this, once again: Criticism of the Israeli government's policies is not antisemitic. Criticism of the Israeli government's policies does not question Israel's right to exist. One should not blindly support one's government. We all

I came here to say the same thing. Folks, we can do without hyperbole on HN. Please keep your BS biases out, and just lay out the facts. The readers are smart enough to decide for themselves.

That may be; but the point is: no one is calling for banning the same BBC here (in the US). Here we accept BBC with open arms, NPR and PBS carry BBC news. I was calling out this double-standard.

Every time Al Jazeera is brought up, people claim that it is anti-semitic, racist, anti-US, etc. But to that I say: so what? Do you think Americans are that stupid that they won't see antisemitism? Do you think we're little children who can

Yep, it's the same thing as "testing on the training set". With memorization, one can achieve almost 100% on the training set. I'm not saying that EDW is doing this, but I'd be very surprised if they could get 92% success rate on real, unse

Anything is available if you're willing to pay enough for it... ;-) As an amateur, the "enough" in the above statement is close to 0. Plus, I don't know what I'd do with NSE data. I'm looking for NASDAQ/NYSE data.

This looks interesting. Even though it's closed-source, the architecture is interesting. As an amateur, I'm always stymied by the lack of data. For intra-day trading, where do you get the data?

"But most people who excel in college are exceling at going deep on something. " I disagree. Undergraduate education is not about becoming the "world's expert at something". That's for grad school and a doctorate. Undergraduate education sh

I think that is because in the old days, brands manufactured their own stuff. Today, major brands subcontract out manufacturing and assembly to some no-name outfit in China. Now, if the owner of said outfit has ambitions, he'd want to sell
