Using Google Latitude to find your location from the JSON feed

jrobertson (James Robertson) — Tue, 24 Nov 2009 14:38:00 GMT

Using the following code it's possible to track your position accurate to 150 meters (updated every 10 minutes). It is assumed you are already subscribed to Google Location and that you have enabled the Public Location Badge [google.com].



require 'open-uri'

require 'json'



url = 'http://www.google.com/latitude/apps/badge/api?user=-1375592218544148424&type=json'

buffer = open(url, "UserAgent" => "Ruby-GoogleLatitude Reader").read



result = JSON.parse(buffer)

features = result['features'][0]; properties = features['properties']



longitude, latitude = features['geometry']['coordinates']

timestamp, placename = properties['timeStamp'], properties['reverseGeocode']



last_update = Time.parse(timestamp.to_s.insert(2,':')[0,5])

location = [latitude, longitude, placename, last_update.strftime("%I:%M%p")]

puts "jrobertson is currently located at %s, %s (%s, updated: %s)" % location



#=> jrobertson is currently located at 55.951295, -3.176071 (Edinburgh, City of Edinburgh, UK updated: 12:59PM)

Inserting a string into a string

jrobertson (James Robertson) — Tue, 24 Nov 2009 14:18:36 GMT

Source: Class: String [ruby-doc.org]

Inserts other_str before the character at the given index, modifying str. Negative indices count from the end of the string, and insert after the given character. The intent is insert aString so that it starts at the given index.



"abcd".insert(0, 'X')    #=> "Xabcd"

"abcd".insert(3, 'X')    #=> "abcXd"

"abcd".insert(4, 'X')    #=> "abcdX"

"abcd".insert(-3, 'X')   #=> "abXcd"

"abcd".insert(-1, 'X')   #=> "abcdX"

or
"abcd".sub(/^.{2}/,'\0X') #=> abXcd

www.aypearl.com interpret Features of Gemstone Jewelry

fairy0610 (fairy) — Tue, 24 Nov 2009 06:33:00 GMT

When it refers to the semiprecious jewelry that everyone more or less likely to understand, but to gemstone jewelry do not know whether you know a half.

In fact, like precious stones and minerals in general, are mined from the earth's crust in the product. Reason is called a "semi-precious stones" because of its stripes, hardness, color, transparency, durability, rarity, crystal form and degree of market acceptance of recognition, are different from other minerals, so it has a special ornamental decorative purposes. With different precious stones In addition, the higher the output of semi-precious stones, compared with Pearl jewelry and diamonds, it is not so expensive.
Many people are fascinated with gemstones as they symbolize beauty, grace and style. Moreover, gemstone jewelry is durable, and they also have religious and astrological significance. For this reason, gemstones should be chosen with great care and preferably be verified by gemologists and jewelry professionals.
Including four kinds of precious stones, namely diamonds, rubies, sapphires and emeralds. While the rest of the gems, such as crystal jewelry, agate, pearl, carnelian, etc. are all semi-precious stones. Although there is no semi-precious stones such as diamonds, precious gemstones, but also highly decorative and collectible value. A wide range of semi-precious stones, the more common are: a variety of crystal jewelry, agate, pearls, amber and so on, other issues such as coral, malachite, olivine, Tiger's Eye semi-precious stones and so on.
People are enamored of gemstone jewelry, particularly gemstone rings, presumably for their stylish and quite often eye catchy finish. Much sought-after gemstone jewelry is gemstone necklaces. These gemstone necklaces again come in different styles - made with small stones, with midsize stones and large stones.
When choosing jewelry, make sure that it has the potential to be mixed with other jewelry for achieving a different look without changing around too many pieces. The one distinct feature of gemstone jewelry is its versatility because gemstones are of different types - blue sapphires, jades, red garnets, zirconium, quartz, ruby, diamond, emerald, coral, pearl, opals and onyx - and available in a plethora of colors and countless combination of gemstones can be used in making gemstone jewelry.
gemstone jewelry consisting of rings, gemstone necklaces, anklets, earrings and bracelets reflect and at times, enhances the personality of the wearer. Apart from the technological, scientific, and metaphysical significance, investors and hobbyists are also fond of buying gemstones for their relative rarity, their unmatched elegance and pride of possession.
It is a matter of deep concern that many stones are becoming increasingly scarcer because the earth is not producing them prolifically as it used to, and stocks of these stones are getting slowly depleted in the secondary market.

Sinatra-Rscript: Unifying the transformation of XML documents

jrobertson (James Robertson) — Tue, 24 Nov 2009 00:32:12 GMT

To render HTML in Sintra-Rscript the following code will transform an XML document (in RecordX format) with an XSL link emdedded in the summary of the document.

If the XML document does not contain the XSL URL then the registry is used to retrieve the XSL URL.



out = render_to(:content_type => 'html', :doc => doc)



# ...



def render_to(opts={})  

  o = {

    :content_type => 'html',

    :file_path => ''

  }.merge(opts)



  cat_doc = o[:doc]

  file_path = o[:file_path]

  text_xsl_url = cat_doc.root.elements['summary/xsl_url/text()']



  if text_xsl_url.is_a? REXML::Text then

    xsl_url  = text_xsl_url.to_s

    h = {}

  else

    xslid = run_projectx('registry', 'get-key', :path => 'system/xml_root/directory/xslid').first

    xsl_url = run_projectx('registry', 'get-key', :path => 'system/xslid/' + xslid).first



    filename = File.basename(file_path)



    parent_file_path = File.dirname(file_path)

    parent_file_path.sub!(/\/?[^\/]+$/,'') if filename == 'dir.xml' 



    if File.dirname(file_path) == '.' then

      parent_file_path = '' #'/dir.xml'

    else

      parent_file_path = '/' + parent_file_path  + (parent_file_path.length > 0 ? '/' : '') + 'dir.xml'

    end



    h = {:params => ['parent_dir', parent_file_path, 'current_dir', File.dirname(file_path)]}

  end



  url = 'http://rorbuilder.info/r/heroku/guide.xsl'

  xsl_doc = Document.new(open(url, "UserAgent" => "Sinatra-Rscript").read)



  node = Element.new('xsl:include')

  xsl_doc.root.add_element node

  node.add_attribute('href', xsl_url)

  @content_type = "text/" + o[:content_type]

  

  nokogiri_transform_doc_xsl(cat_doc, xsl_doc, h)

    

end

Currently it's assumed the XML file which doesn't have an embedded XSL_URL will be a dir.xml file.
