   But does the college ever get to hit it big in Australia? If one of your students goes on to earn millions do you get 3% of that? Or is it capped at some value?

   What if I took a screenshot of the website? That threat seems awfully weak I'd like to think that most employers would be willing to accept even though the website took my name down I still had the education in my brain and would still

   I have a guess. In 1952 FIDE reworked the rule about draws by agreement removing a clause which prevented players from agreeing to a draw before move 30. This is something that isn't mentioned in the article and I think really should b

   I'm pretty sure all of the purchases result in the same 75-25 split so that part of the math isn't wrong. It's just that fewer total people have donated that amount.

   Hi, I wrote the multi-index code and got this release shipped so I guess my opinion might be worth something on it. The answers I read to questions like this normally strike me as very tautological. Things like "you need your team to b

    These sound like very good ideas. I'll see if I can get them implemented. Thanks for the suggestions.

    Anyone have any idea when this was written? Some of it seems a little bit dated although I would not be surprised if Alton still holds these beliefs.

    This absolutely screams pseudo science. Every single time the article says "we measured X" X is qualitative and subjective. They don't give any information on how X translates in to the numbers they're presenting.

    To be fair I think those are hints that improve performance rather than required syntax. The question I guess is whether these are "optional" in the sense that you get horrendous performance without them or truly optional and you

    I know the answer to your last question which is that the SSD optimized code is all present as the serializing layer so running on SSDs will provide a significant performance boost. I'm not 100% sure what provisioned-IOPS EBS is but I&

    "Augmenting the human condition" is admittedly a bit of a platitude (and a bit grandiose). However your question "under whose criteria does rethinkdb qualify for this?" is exactly the right one and the actual lesson from

    RethinkDB has an API that's very capable of doing CRUD operations (and a lot more). Probably the only way it could not fill your CRUD needs is if you didn't like the ways you can access it. We have official drivers for Python, Rub

    Another nice way to do this is: r.expr(range(2, n)).reduce(lambda x,y: x+[x[y-1] + x[y-2]], [0,1])

    Is there ever going to come a point where rather than hooking my Tesla up and charging it I just drive up to the station and swap out the battery for a new charged one? This seems to help mitigate one of the biggest problems which is how lo

    You can use multiple indexes in some queries. The case you described will work. However you can't use multiple indexes from the same table. For example: table.between(...).between(...) won't work. You'd have to use a filter (and thus

    Thanks. If we can succeed in being Mongo without the gotchas we'll be very happy.

    Thanks, we've gotten a lot of mileage out of the following ethos: Let users ignore danger, but never let users ignore the fact that they're ignoring danger. Always give users a way to learn exactly what the dangers are. In the case of the q

    An optimizer can be right most of the time but it's basically impossible to have it be right all of the time. It really depends on what you're doing as to which approach you prefer. If you absolutely need a query to have a certain performan

    Data has always been indexed it just was only indexed by a single primary key. Before this release the indexing scheme wasn't more sophisticated than a key value store now it is. I feel like there are several other products on the market th

    That's something we'll make sure to keep around indefintely. I always hate things that are too magically, which optimizers frequently seem to me, but I also get why they're useful to people. The best compromise I think is to give people the

    Hi, I implemented secondary indexes in RethinkDb. This was an intentional choice we made for a couple of reasons. The most pragmatic one was that we don't have an optimizer and we thought that secondary indexes could still be useful to a lo
