So you might have set up dnsmasq with this tutorial but then you notice that you can't set cookies to subdomains of localhost or for all of localhost's subdomains (see why).

So we set up a custom "localhost", that I'll call local.host, but you can pick whatever you want, as long as it contains at least one dot. Just adapt the first two commands.

$ # add to hosts list
$ sudo echo "127.0.0.1 local.host" >> /private/etc/hosts
$ # tell your dns server about it

A friend asked me for a few pointers to interesting, mostly recent papers on data warehousing and "big data" database systems, with an eye towards real-world deployments. I figured I'd share the list. It's biased and rather incomplete but maybe of interest to someone. While many are obvious choices (I've omitted several, like MapReduce), I think there are a few underappreciated gems.

Running nightmare on Amazon Linux

You may have thought of running nightmare on AWS Lambda. But before we can run it on Lambda, we need first to make it run on Amazon Linux.

Provision instance which replicates Lambda environment

According to AWS Documentation on Lambda Execution Environment and available Libraries we would need this AMI image with this alias amzn-ami-hvm-2016.03.3.x86_64-gp2. Keep in mind that AMI-image-id for this instance would be different in different regions (eg):

• In eu-west-1 - ami-f9dd458a
• In us-east-1 - ami-6869aa05

First, install dnsmasq using brew:

$ brew update
$ brew install dnsmasq

Then create your configuration

// data comes from here http://stat-computing.org/dataexpo/2009/the-data.html
// download 1994.csv.bz2 and unpack by running: cat 1994.csv.bz2 | bzip2 -d > 1994.csv
// 1994.csv should be ~5.2 million lines and 500MB
// importing all rows into leveldb took ~50 seconds on my machine

// there are two main techniques at work here:
// 1: never create JS objects, leave the data as binary the entire time (binary-split does this)
// 2: group lines into 16 MB batches, to take advantage of leveldbs batch API (byte-stream does this)

var level = require('level')
