Been playing with Googlemaps

Been playing with googlemaps and rails. The first step is geo-coding the address to Lat long coordinates.

Here is my first play code

require 'net/http'
require 'uri'
require 'rubygems'
require 'builder'

addrs = [ "1600+Amphitheatre+Parkway,+Mountain+View,+CA",
"1159 Gympie Rd Aspley QLD 4034 ",
"14 Morayfield Rd Caboolture QLD 4510 ",
"521 Ipswich Rd Annerley QLD 4103 "
]

placemarkbase = 'List'
placemarks = Hash.new

xml = Builder::XmlMarkup.new(:target => $stdout, :indent => 4)

geocoder = "http://maps.google.com/maps/geo?q="
output = "&output=csv"
apikey = "&key=### insert your googlemaps token here ###"

counter = 0
addrs.each do |addr|
request = geocoder + addr + output + apikey
sleep 2.0
url = URI.escape(request)
resp = Net::HTTP.get_response(URI.parse(url))
fields = resp.body.split(',')
placemarks[placemarkbase + counter.to_s] = [addr,fields[3],fields[2]]
counter += 1
end

kml = { 'xmlns' => 'http://earth.google.com/kml/2.2'}
xml.instruct! :xml, :version => "1.1", :encoding => "US-ASCII"
kml.each do |key,value|
xml.kml(:xmlns => value) do
xml.Document do
placemarks.each do |key, array|
xml.Placemark do
xml.name(array[0])
xml.address(array[0])
xml.description(placemarkbase)
xml.Point do
str = array[1].to_s + "," + array[2].to_s + "," + 0.to_s
xml.coordinates(str)
end
end
end
end
end
end

Action Hack: features research on github

During Action Hack I did a quick scan of GitHub.

Was looking for ideas for laying out and grouping features. I looked at 20 projects that had features folders.

Almost all of them just had a flat structure. Simply features files named for groups of features.

The one exception had sub directories that grouped the feature files by release.

Would be interested in hearing how people layout their features.

Ruby: Cloud Crowd

This post is only a heads up. Seen Cloud Crowd talked about. Looks interesting, but not used it myself yet.

Ruby: Playing with Colour

Had an idea for a new twitter background.

I wrote it in ruby, using the rmagick API wrapper for ImageMagick.

Pretty straight forward:

  • make a big black background,

  • create a lot of random coloured squares and write the colour on them while you're at it,

  • write to jpeg file


Here's the code.

require 'rubygems'
require 'RMagick'
include Magick

buffer = Magick::Image.new(1700,1040) { self.background_color = "#000000" }

x = 10
y = 10
tone = [ '0', '1', '2', '3', '4', '5', '6', '7',
'8', '9', 'A', 'B', 'C', 'D', 'E', 'F' ]

srand 1234
1118.times do
puts '* '+x.to_s+' '+y.to_s
red = rand(16)
green = rand(16)
blue = rand(16)
ligthness = red+green+blue
co = '#'+tone[red]+tone[green]+tone[blue]
patchObj = Magick::Draw.new
patchObj.fill = co
patchObj.polygon(x,y,x,y+30,x+30,y+30,x+30,y)
patchObj.matte(3,3,PaintMethod::ReplaceMethod)
patchObj.draw(buffer)
textObj = Magick::Draw.new
textObj.font = './fonts/Ghoul.ttf'
textObj.pointsize=12
if ligthness > 25 || green > 11
textObj.fill = '#000'
else
textObj.fill = '#fff'
end
textObj.text(x, y+12, co)
textObj.draw(buffer)
x = x+40
if x > 1690
x = 10
y = y+40
end
end

buffer.display
buffer.write("random_colour.jpg")

exit

Enjoy.

#ToDo: use a resource pool so don't have the cost of creating over 2K Draw objects.

BarCamp Brisbane

I came, I saw, I had fun.

Lots of great talkfest on tech, culture & business.

Should have posted this almost two weeks ago.

BarCamp Brisbane III was in East Brisbane on the 18 July. Well worth the trip. It's part on BarCamp Queensland (yes, there is a BarCamp Gold Coast).

CSS background images & Rails

Setting a CSS background image in Rails have one quirk, when using a relative url, the base directory is not the base directory of the project. It's the directory where the stylesheet CSS file lives. So the correct relative url is this;

#wrapper1 {
background: url(../images/background.gif) repeat left top;
}

when the image & stylesheet live in the usual places.

Symfony: rails-ish PHP?

A friend has asked me to help on a site he wants to develop. It's in a PHP environment. This is not a language I've worked in before. A chance to learn.

Looking around I've come across what look like a rails like framework called Symfony. Not used it yet.

I have a project directory structure like rails and is based in the Model View Controller (MVC) pattern.

Should be interesting. Anyone got any comments?

Don't default the disk

Playing with Mythbuntu this weekend.

First lesson, don't let it default to one partition. I had problems finding /boot (I think). After some googling, the most likely cause is partitioning?

About to repartition. Lets see how it goes.
