• Who are the most important people in open-source software? [closed]

  - by poseid

  I am reading a book by Malcolm Gladwell on the circumstances of successful careers. The book argues that Bill Gates, Steve Jobs, Bill Joy and more succesful computer pioneers were born between 1950-1955, and did absolve around 10000 hours of practice before microcomputers became widely available in the 1970s and their fairy tale success story begins. As we are in the age of web 2.0 with new forms of databases and persuasive access to information, who are in your opinion the most succesful computer programmers or scientists of our times, when were they born and to which technologies they had access?

• Amazon S3 collisions with heroku and paperclip

  - by poseid

  I have an app on my localhost for development and an app for testing on heroku. Image upload with localhost and paperclip always works. However, doing the same experiment with image upload on my heroku app, the app hangs... and the upload seems to be going on forever. I suspect that there is a collision going on. What is needed to get but uploads working? Or do I need to use different buckets for each environment?

  - by poseid

  I am using the plugin: http://github.com/karmi/is_taggable How can I perform simple statistics on my tags, e.g. what's the most used tag? which tags are not used, etc.?

• Display loading while webservice is running

  - by poseid

  On the initial request to a page, I trigger a webservice and want to display a loading message. When the page has finished loading, I want to remove the waiting message from screen, but display it again when a change event in a checkbox triggers an Ajax call with another loading message. This code is not behaving to the given spec: $(document).ready( $(function() { $('#loadingDiv').hide(); $('#productsDropDown') .change(function() { var prodValue = $(this).val(); $('#proddate').load('getpdate.php', {prod: prodValue }); }); $('#loadingDiv') .ajaxStart(function() { $(this).show(); }) .ajaxStop(function() { $(this).hide(); }) ; }); ); what am I doing wrong?

• Rails: textfield list to array of strings

  - by poseid

  I want to take input from a textfield and turn it into an array of strings. After having submitted the "post", I want to display again the textfield, but with the array showed below. I have a view that would look like: <% form_tag "/list2array" do -%> <%= text_area_tag "mylist" %> <div><%= submit_tag 'save' %></div> <% end -%> <% @myArray.each do |item| %> <%= item %> <% end %> And as a start for the controller: class List2ArrayController < ApplicationController def index end def save @myArray = params[:mylist].split("\r\n") end end However, after the post, I only get an empty textfield without values in the array from the previous POST. Do I need to use the model layer for my experiment? How? Or do I need to modify my controller?

• allow waiting user experience while file upload with rails and jquery

  - by poseid

  I am trying to display a waiting spinnger, while uploading a file. I am able to show the spinner, and to do the upload, when doing it individually. My problem is how to combine these two. The Jquery Javascript looks like: <% javascript_tag do %> function showLoading() { $("#loading").show(); } function hideLoading() { $("#loading").hide(); } function submitCallback() { showLoading(); $.post("create"); } <% end % My form looks like: <% semantic_form_for @face, :html => {:multipart => true} do |f| %> <%= f.error_messages %> <%= render 'fields', :f => f %> <p> <%= button_to_function 'create', "submitCallback()" %> </p> <% end %>
