I've benchmarked Tokyo Tyrant, MongoDB, and Redis for a smaller dataset (~20gb). We ended up going with Tyrant because it stored our serialized data more efficiently than the others. That index lives in memory on a big ec2 instance. The dat

Thanks for the extensive answer. We buy a lot of data that comes in four times a year for our interactive mapping engine. Initially I would only want to update that data every quarter. That said, if I get a system like this up and running,

Honestly, I kind of wasn't aware that biofeedback worked that way. Has anyone else gone through this?

Depends on the purpose. Our GIS department uses PostGIS for one off analysis. Our interactive mapping engine uses Shapefiles with quadtree indexes.

You're going to enjoy spending time with Invisible Cities by Italo Calvino. It's mostly metaphor, his writing style is quite vivid. The interactions of people and things in his fictional cities touch on many facets of what it is to be alive

I have seen this kind of thing before, but the specific images on this post were well worth seeing. You get such a more intimate sense of the environment, especially in the third and fourth images.

I guess I didn't really garner any intellectual pleasure from this article. Feels more like something i'd see over at digg. Marginally entertaining at best. Not really what I'm used to seeing on HN.

I've been deep into building a geocoder the past month. While we may get rid of Solr eventually, it was a great foot in the door to information retrieval. It helps that I have a problem to solve and a deadline, so I'm motivated to read and

The community matters. PHP had a hard life growing up in the early web. Googling for answers in php will often promote bad programming practices, like putting all your code in one file. The ruby and python communities are a bit more interes

The pomodoro technique seems like allowing yourself a hit of heroin every few days, even though you know it's a problem. I've never been able to follow it for long enough for it to be effective. Any tips?

I'd say it's not mutually exclusive. The sudden ability to take out those whom your government feels is "doing wrong" without being concerned about potential collateral damage is a new thing indeed. It makes war more palatable, less like th

A good point, yet that again causes an escalation of an "arms race" of this kind of weaponry. It's also a matter of logistics, where do you deploy the anti-sniper drone equipment? Around everywhere a sensitive target may go? I suppose I'm n

This is one of the most frightening things I've seen on HN. A fleet of these killing machines would be so much more effective than ground troops at "killing the enemy". What bothers me is that if these are so much cheaper to make, and more
