• How do i create multiple URLs with /controller/action/ format?

  - by Angela

  I have several controller/actions where no :id needs to be passed. what I did with the first two was make a custom route defining the controller and action. I thought that the default would allow me to create controller/action.xml by using respond_to in the controller, but that doesn't appear to be the right way. How can I create controller/action URL's (some are .xml) without creating a special route with map.connect?

  I am trying to figure out how the search tool in a web browser is being able to parse through the entire web page(assuming huge content on a page) and highlight the result as we type. Does it pre-cache the page while loading in a map or use regex to get a quick result on the fly?

• How much memory does a hashtable use?

  - by Michael

  Would a hashtable/hashmap use a lot of memory if it only consists of object references and int's? As for a school project we had to map a database to objects (that's what being done by orm/hibernate nowadays) but eager to find a good way not to store id's in objects in order to save them again we thought of putting all objects we created in a hashmap/hashtable, so we could easily retrieve it's ID. My question is if it would cost me performance using this, in my opinion more elegant way to solve this problem.

  I have fairly large map overlay that I am displaying over the google maps data but would still like to see the country/state/province lines through my overlay (so the lines would essentially be on top of my overlay). As I understand, these lines are simply polygons drawn over the maps. Is there any way to access these? If so, how do I get them to show up through my overlay images?

• Network bandwidth bottleneck for sorting of mapreduce intermediate keys?

  - by Zubair

  I have been learning the mapreduce algorithm and how it can potentially scale to millions of machines, but I don't understand how the sorting of the intermediate keys after the map phase can scale, as there will be: 1,000,000 x 1,000,000 : potential machines communicating small key / value pairs of the intermediate results with each other? Isn't this a bottleneck?

• How do I provide basic configuration for a Scala application?

  - by Dave

  I am working on a small GUI application written in Scala. There are a few settings that the user will set in the GUI and I want them to persist between program executions. Basically I want a scala.collections.mutable.Map that automatically persists to a file when modified. This seems like it must be a common problem, but I have been unable to find a lightweight solution. How is this problem typically solved?

Thanks!

• Python: How can I read in the characters from a line in a file and convert them to floats and strs, depending on if they are numbers or letters?

  - by user1467577

  I have a file that looks like: 1 1 C C 1.9873 2.347 3.88776 1 2 C Si 4.887 9.009 1.21 I would like to read in the contents of the file, line-by-line.

How can I make it store the letters as strings and the numbers as floats?

• R programming function without ()

  - by Mark Kennedy

  So, I Have the following very simple map.r file. I'm trying to have the user type "click" in interactive mode and then have the function . Since it's a function, the user has to type "click()" how can I make it so that they only have to the word (w/o parentheses), and then have that function do something with the img. So the user types: mydist("image.pnm") click //And then the function click does what it's supposed to mydist <- function(mapfile) { img <- read.pnm(mapfile) plot(img) } click <- function() { //Prompt user to click on img }

• Confused about distinct/aggregate queries with (N)Hibernate

  - by nw

  I'm not sure how to approach queries that don't map 1:1 to my persistent entities - in other words, distinct and aggregate queries. For example, I need to retrieve a distinct list of property values for populating a drop-down list. Should I write a class and a mapping for the "entities" that are returned by this query? Or should I just use the native DB provider and work with native data sets instead?
