One approach to expression indexes on JSON would be a multicolumn index. Column A is the path, e.g. "foo.bar[2].baz" and column B is the value at that path... of course you'd need to use GIN -- which as mentioned already is slow to build

I suppose the takeaway is meant to be: why bother having two separate data storage systems (relational + schemaless) if only one will do? I mean, if Mongo isn't offering much (if any) performance gain or schemaless flexibility... what's

Where's the print stylesheet? Many times a plain PDF printed out on a stack of dead trees is still the best way to pitch. Unfortunately it's a PITA to build good-looking PDF decks in standard presentation tools... would be awesome to just

I've been on the beach in Thailand hacking with fellow HNer @mv this week, and we've just launched our first little project. More to come so stay tuned. :) Big shout-outs to Bootstrap, Flask, and Amazon EC2 for making it so easy (and cheap

I don't have a Twitter account. Is it too hard to add at least one other signup method for folks like myself?

> But 180 chargers, peak, each using 100 kilowatts would use 18 gigawatts. Hmm, I think you mean 18MW, not 18GW... sure, it's still a huge amount of energy, but your typical data centre can easily consume 10MW or more. And 18 megaw

Happily, Postgres keeps improving performance with each release. According to benchmarks [1], the upcoming version 9.2 will scale up to 64 cores for read-heavy workloads. Unless your application is going to grow really fast -- keeping i

It's a slightly contrived example, because in a real-world schema you would want enough information about each line item that an array isn't practical. But I don't think locks are an issue here, because no sane business process would need

It's very sad to see Pacific Fibre shut down, because they had done an incredible amount of work to get the major corporate and political players on board. They were basically putting forward the only credible plan to lay a new cable, and

But if the CDN is serving your static assets, your origin webserver only has to generate them once [1] to populate the CDN. It almost doesn't matter how long this takes. And this works well enough that you don't need to bother setting u

There's a good post from late 2011, in the context of 12-factor deployment on Heroku, where the author muses about just using a pure Python server behind a CDN to serve static content: ...and yeah, I think I should bloody use this server a

A hook that I've found useful (though not perfect -- esp. when working on many branches) is to check that "pip freeze" and requirements.txt match before allowing a commit. My hgrc has the following line for this: [hooks] pretxnco

The (crazy but awesome) "unicode literals" feature in Python 3 means that your example is actually a valid statement: Python 3.2.3 (default, May 3 2012, 15:51:42) [GCC 4.6.3] on linux2 Type "help", "copyright", "credits" or "licen

It seems to me that almost all of the issues revolved around the complicated EC2/EBS control systems. Time and time again, we hear about an AWS failure which resulted in brief instance outages. If it was just a dumb datacentre, the affe

Definitely the case. They've put a lot of effort into bringing on new hosts this past year, to the point that I've noticed a distinct slowdown in bookings recently. I'm all for Airbnb focusing on demand now. :)

As an Airbnb host, I'm worried that this new homepage has too much going on. The old design really emphasized the "Where are you going?" search box, which led quite naturally on to the listing results page. Also, many of my guests are mak

In fact, the 7-11 and Circle K here are so cheap that often times even buying in bulk, you can't beat their prices. And then there's the convenience factor: literally 30 seconds to grab what you want from the fridge and pay for it with th

So in other words, OSM has done a pretty good job of mapping the _streets_ of the world, and now it's time to shift the focus to recording the individual _address points_ along those streets? AFAIK, the tags to use for individual address po
