Chrome usage, a comparision US-MX

Update 2: Data from Feb.-March’09

Update: I’ve added a more recent (January ’09) statistic at the end.

To complement my last post on the usage of Chrome, I’m posting data from Net Applications referenced by Computerworld, and our data:

Chrome #4 on OCCMundial.com

Google Chrome ranks #4 with 0.51% of visitis on OCCMundial(my employer) as of today, from Sept 2. It ranks over Opera (0.27%) and below Internet Explorer (90.54%), Firefox (7.29%) and Safari (1.26%). OCCMundial is the leading online Job Board in Mexico, with more than 100 million pageviews per month.

And yes, it’s noticeable the margin of IE over every other browser, which I think can be extrapolated to the whole usage of browsers in Mexico since our traffic it’s pretty high for this market. (Data from Google Analytics).

On Artistic Taste and Psychology

How psychology accounts for taste development Via Psychology Today

“We wrongly assume, for instance, that people with highly decorated and cluttered rooms are more extroverted. We also assume such people are more open—when really we should be looking for variety in books and music, for books on art and poetry, and for art supplies. We assume that rooms with stale air belong to emotionally unstable people—when really we should be scanning for inspirational posters”

On Peter Donnelly Conference at TED [Ruby]

A small Ruby script to test Peter Donnelly’s example on uncertainity. Conference below..

def avg_pat(pat, t, s=0)
  t.times do 
    last = ''
    last += (rand(2)==0 ? 'H' : 'T') while last[-pat.length..-1] != pat
    s += last.length 
  end
  s/t
end	

['HTH','HTT'].each{|p| print "#{p} #{avg_pat(p,10000)} "}

IronPython: Catching exceptions

Don’t know why this wasn’t easy to spot. To catch an exception and display the StackTrace on IronPython use:

import sys

try:
	print "hola"
	print 3/0 #Select which exception to test
	raise Exception("Error...")
except Exception, e:
	print e.clsException

 

Rails: Fast & Easy Sitemaps

Few lines to get your sitemap. Also, add a hash array for the other links on your site:

Sitemap controller:

    @sites = [
	    {:loc=>url_for(:controller=>'home',:action=>nil), :lastmod=>File.open('web/app/views/home/index.rhtml').mtime.strftime('%Y-%m-%d')},
	    {:loc=>url_for(:controller=>'blog',:action=>nil), :lastmod=>File.open('web/app/views/blog/index.rhtml').mtime.strftime('%Y-%m-%d')},
	    {:loc=>url_for(:controller=>'casa',:action=>nil), :lastmod=>File.open('web/app/views/casa/index.rhtml').mtime.strftime('%Y-%m-%d')}
    ]

 

RXML:

  @sites.each do |site|
    xml.url do
      xml.loc( site[:loc] )
      xml.lastmod( site[:lastmod] )      
    end	    
  end
