What an evil idea. Track Google searches from your corporate proxy and use some Google-trends-like analytics on these data. This would offer a glipse of your true corporate culture.

Humans can't disambiguate in the sea of words as effectively as machines do. There is just too much results you have to sift through, every time you want to look up some little detail.

No. And it doesn't have anything to do with any deficiency MySQL may have - RDBMS is not an OK replacement for a log file.

No, it's just another case of RDBMS blinding people for all other possible solutions.

I'm really interested in what would make it really awesome for you. In particular, is the cleanup/database part important for you? If you or anyone on HN wants to talk about it (and especially if you've tried http://siteparse.com ), my ema

What we are doing is not really ready to launch, but we match the first part of this description perfectly ("a GUI-based way for nonprogrammers to scrape data"). The GUI is web based, you can watch a demo and try us out immediately (you get

Design in an abstract sense that encompasses both visual and systems design probably includes designing programs (coding) as well. So it doesn't say much.

By Zimbabwean standards we are all rich I guess. Bartering (or even trade in a foreign currency) adds so much friction that all but the most necessary and unsophisticated transaction simply don't happen.

Ok, I didn't look up the numbers. The inflation in January 1997 alone was 380%. This means the stores (the ones that are still open) write new price tags during the day. I know this is inconceivable to most people, pretty much in the way fa

I have seen what happens when elected politicians print money by popular demand. Hyperinflation, money are worth 3-5% of their value from a few years ago, economy halts. Bulgaria in 1996, and you don't want to go there.

Painful? I read only the ones that interest me (quickly judged from elevator pitches) and it's exciting!

Machine learning tends to need specialized datastore infrastructure as well (look at DirectedEdge or the full text search indices). I'm curious, what is your project about?

REPL also helps me stay focused. Maybe for some people TDD does, but not for me.

Selection bias would mean people who opt in get better recommendations... sounds like a good incentive and a virtuous circle to me.

The spot prices for the large EC2 instance seem really close to the price of on-demand instances: $0.34 from the N. Virginia data center. I guess Amazon will not be reducing their prices anytime soon.

No, Redis is single-threaded so they sidestep all concurrency issues. This and persisting the data in a forked process are my favorite parts of Redis' architecture.

I was looking at Redis yesterday and noticed this. Is there any particular reason you chose skip list instead of btrees except for simplicity? Skip lists consume more memory in pointers and are generally slower than btrees because of poor m

Probably no. But there is more complex psychology and economics involved: http://www.jimmyatkinson.com/papers/ticketscalping.pdf

The article says: "You can almost always use a simple locked data-structure for synchronization fairly painlessly (and with a bit of practice, you can usually write one fairly painlessly, too)." If we focus on the first part, in my experien

Has the author really written lots of multithreaded code? Lots of people think they understand multithreading because they understand the synchronization primitives. "I'll just share this synchronized HashMap among my threads and everythi

I thought the same. However some content would be better for you and some content would be better for your competitors, and the advertising budgets should be allocated according to the generated sales. Suppose the content in question is an

All those little yellow boxes -- the ones many Google searchers think mark the extra quality results (no joke!) Citation needed.

Yes, there is plenty of room for improvement. At least make it possible to browse the site by more than one tag and fix the search engine.

Someone has been envious on the Vark acquisition :-) Of course VC makes sense in their case. There is no barrier to entry in this field, the model is clear: * users tend to type questions in search engines * search engines tend to rank up e
