This function will resize any input file restricting the width and height to be no more than the specified pixels, and output a binary stream.
<pre>function resize_jpg($inputFilename, $new_side){
$imagedata = getimagesize($inputFilename);
$w = $imagedata[0];
$h = $imagedata[1];
if ($h > $w) {
$new_w = ($new_side / $h) * $w;
$new_h = $new_side;
} else {
$new_h = ($new_side / $w) * $h;
$new_w = $new_side;
}
$im2 = ImageCreateTrueColor($new_w, $new_h);
$image = ImageCreateFromJpeg($inputFilename);
imagecopyResampled ($im2, $image, 0, 0, 0, 0, $new_w, $new_h, $imagedata[0], $imagedata[1]);
return $im2;

If you need to be sure that a user can view an object, you need to check the View permission not only on the object but also all of its parents. To do this, I slightly modified the script at http://zopelabs.com/cookbook/1018022911 so that it uses the context object and specified the View permission.
Create a Python script in your acquisition path (I used portal_skins/custom) named can_view and paste in this code:
permission = "View"
try:
object=context
if not object.acquiredRolesAreUsedBy( permission ):
for p in object.rolesOfPermission( permission ):
if p['selected']:
if p['name'] in user.getRoles():
return 1
else:
return 1
except:
pass
return 0
Then you can check the permission in TAL like this:
<div tal:condition="some_object/can_view"> ... </div>
you can use this function to convert an integer into any number system upto base36 (e.g. for TinyURL generation coupled with a global ID counter)
function int2baseX($val,$base=16) {
if (0==$val) return 0;
$symbols='0123456789abcdefgihjklmnopqrstuvwxyz';
$result='';
$exp=$oldpow=1;
while($val>0 && $exp<10) {
$pow=pow($base,$exp++);
$mod=($val % $pow);
$result=substr($symbols,$mod/$oldpow,1).$result;
$val-=$mod;
$oldpow=$pow;
}
return $result;
}
A minimal example to let you choose from you mobile phonebook.
import contacts, appuifw
db = contacts.open()
names = []
numbers = []
for i in db:
names.append(db[i].title)
num = db[i].find('mobile_number')
if num:
numbers.append(num[0].value) # first mobile
else:
numbers.append(None)
i = appuifw.selection_list(names)
print 'number =', numbers[i]
Go to /home/virtual and run:
find -type l -maxdepth 1 -name '*.*' | xargs -n 1 basename | xargs -i find /home/virtual/{}/var/www -type f -size +8192k -ls
You can confirm that your database YAML file is being parsed properly with this one line shell command.
ruby -ryaml -e "File.open('config/database.yml') { |f| puts YAML.load(f).inspect }"
Use this objects:
java.util.Stack (LIFO) java.util.LinkedList (FIFO)
# put this in lib/active_record/json.rb
require 'json/lexer'
require 'json/objects'
module ActiveRecord
module Json # :nodoc:
DEFAULT_CONVERSIONS = { Time => [:to_s, :db] }
def to_json(conversions = {})
conversions = DEFAULT_CONVERSIONS.merge(conversions)
self.attributes.keys.inject({}) do |hsh, key|
value = self.send(key)
hsh.merge(key => conversions[value.class] ? value.send(*conversions[value.class]) : value.to_s)
end.to_json
end
end
end
# in environment.rb do
#require "#{RAILS_ROOT}/lib/active_record/json"
#ActiveRecord::Base.class_eval { include ActiveRecord::Json }
Doing something like
<%= var post = @post.to_json %>
in a javascript snippet should allow you to use the basic AR attributes such as post.title, post.summary (using the Weblog analogy). You could also pass the json bits to a javascript function.
//simple general rand function
float randBetween(float min, float max)
{
return llFrand(max - min) + min;
}
//uses randBetween to generate a random colour vector
//maybe a bit of overkill, but can be repurposed.
vector randColour()
{
vector r_colour = <randbetween 0,1), randBetween(0,1), randBetween(0,1)>;
return r_colour;
}
The R FAQ states:
par(mar = c(7, 4, 4, 2) + 0.1)
plot(1 : 30, xaxt = "n", xlab = "")
labels <- paste("Label", 1:30, sep = " ")
text(1:30, par("usr")[3] - 0.25, srt = 90, adj = 1,labels = labels, xpd = TRUE)
mtext(1, text = "X Axis Label", line = 6)

At the prompt, type this:
defaults write com.apple.screencapture type image_format
Replace "image_format" with a file format name, like pdf, png, tiff, etc. Then to take screenshots, Cmd+Shift+4, then drag around the area you want to capture.
data <- sort.data.frame(data, key = "LOC")
where the function "sort.data.frame" is as follows:
sort.data.frame <- function(x, key, ...) {
if (missing(key)) {
rn <- rownames(x)
if (all(rn %in% 1:nrow(x))) rn <- as.numeric(rn)
x[order(rn, ...), , drop=FALSE]
} else {
x[do.call("order", c(x[key], ...)), , drop=FALSE]
}
}
The CSV file "loc.csv" contains the following:
Module LOC a.rb 100 b.rb 120 c.rb 54
The following R code creates the barplot image "loc.png":
data <- read.csv(file="loc.csv", sep = " ", header = TRUE, row.names = "Module")
png("loc.png", width = 640, height = 480)
barplot(data$LOC, names = rownames(data), ylim = c(0, 250), main = "Lines of code by module", ylab = "Lines of code", xlab = "Module")
dev.off()
This lets you load ActionView helpers globally.
RAILS_ROOT/lib/action_view/helpers/widget_helper.rb:
module ActionView
module Helpers
module WidgetHelper
# define helper methods
end
end
end
RAILS_ROOT/config/environment.rb:
require "#{RAILS_ROOT}/lib/action_view/helpers/widget_helper.rb"
ActionView::Base.class_eval do
include ActionView::Helpers::WidgetHelper
end
