A Capistrano Rails Guide

A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

A Brief Guide to Debugging

A BRIEF INTRODUCTION TO DEBUGGING

“As soon as we started programming, we found to our surprise that it wasn't as easy to get programs right 
as we had thought. Debugging had to be discovered. I can remember the exact instant when I realized that 
a large part of my life from then on was going to be spent in finding mistakes in my own programs.”
— Maurice Wilkes, 1949

This is a guide to debugging your projects at ITP and beyond. It is not a guide to specific techniques for debugging Processing sketches or physical computing projects; it is a guide to the basic ideas and goals of debugging.

SSH between Mac OS X host and Virtual Box guest

On Mac OS (host):

Shutdown your VM and do:

VirtualBox > Settings > Network > Add (you will get vboxnet0)

On a terminal ifconfig will show you new interface vboxnet0

VM's Settings > System > check "Enable I/O APIC." VM's Settings > Network > Adapter 2 > host-only vboxnet0

Overview

In general, it seems there are roughly five (5) ways to get "file data" (e.g. a GeoTIFF) out of a PostGIS geoprocessing workflow:

  • Export just the raster field as an ASCII grid
  • Connect to the database using a desktop client (e.g. QGIS) [1]
  • Use a procedural language (like PLPGSQL or PLPYthon) [2]
  • Use the COPY declaration to get a hex dump out and convert it to a binary file
  • Fill a 2D NumPy array with a byte array and serialize it to a binary file using GDAL or psycopg2 [3, 4]
  • Use ST_AsTiff() or the more general ST_AsGDALRaster() to get a byte array, which can be written to a binary file

Example of how to use both JDK 7 and JDK 8 in one build.

JDK 8 Released

Most of us won’t be able to use/deploy JDK 8 in production for a looong time. But that shouldn’t stop us from using it, right?

It should be possible to sneak in JDK 8 in the back way, the same way we snuck in Groovy and other libraries we wanted to use.

The Test Suite to the rescue

The Maven compiler plugin run in two separate lifecycles, compile and testCompile. Those can be configured separately.
