As with most agriculture in the US (assuming you're talking about the US), family farms are the exception - not the rule.

It's just an annoying convention around here. My best guess is because the street address can be one of 5 or 6 cities (Raleigh, Durham, Chapel Hill, Cary, Wake Forest, Morrisville, Apex, etc) and so people talk in terms of the metropolitan

That's correct. I believe they are using it in some new "high availability" stuff coming down the road

I wonder what motivation they had for developing their own BigTable/Dynamo implementation rather than going with Cassandra or HBase. Now there are three Apache projects with quite a bit of overlap (distributed columnar/key-value database).

Aren't they missing a cartel in NM - specifically a large production facility in ABQ?

This reminds me of some early MongoDB benchmarks. Claims of extremely high write throughput when really it's writing to memory and relying on mmap to eventually sync the data to disk. Making write speed claims when you're not touching the d

Not surprised to see Erlang come out on top. As I understand it, this is precisely the type of problem Erlang is good at - doing lots of little lightweight things with minimal overhead.

There was an article about this a few years back: http://blog.linkibol.com/2010/05/07/how-to-build-a-popularit... I've found, in practice, a Bayesian weighted average is easy to implement and pretty effective. It's also a good candidate f

As I recall the written portion of AP science exams was like this. No prose necessary - you could just write a bullet list of the required facts and get full credit

I think that, given the volume of users on reddit and the volume of content they interact with, any of the various collaborative filtering techniques would work well at this point. You could take it a step further and incorporate more than

Depends on what I'm doing. If I'm writing out a lot of text, usually I'll stay hovered near the home row keys (but never resting my fingers on them). However, if I'm in vim, my hands spread apart some to give better access to Esc+Ctrl and S

You'd be hard pressed to generate 2^16-1 ids in a millisecond, so yea - it's probably overkill.

If we're comparing CouchDB's popularity to that of MongoDB's, it's simple - 10gen. 10gen has done a very good job generating lots of hype around their product. I believe they have people dedicated to this task (aka, evangelists). CouchBase

I can't wait for chapters on Mnesia and distributed Erlang. I've been learning Erlang for fun over the past few months and LYSE has been an absolute godsend. Also looking forward to this in book format

Maybe rather than a new language, we should work towards browser "assembly" code. Lots of modern JavaScript development is in the direction of: write in language X, compile to JS. Would be nice if there was a lower-level target than JS

Hive is a really slick DW tool built on top of Hadoop. It has a SQL-like language and supports typical DW techniques like table partitioning, key clustering, etc.

Generally speaking, all incoming requests should be verified - authorized or not. These days with all kinds of wonderful web frameworks, CSRF protection is pretty simple. Django handles CSRF with a token in a hidden form field: https://doc

I think there needs to be some way to store scripts on the server. I like the CouchDB method of a storing a view as a special document. Could use a Hash to store the code along with metadata (version, last modified, etc). That said, if Redi
