  • What does this code do?

    - by Senthil
    I found this in Ryan Bates' railscast site, but not sure how it works. #models/comment.rb def req=(request) self.user_ip = request.remote_ip self.user_agent = request.env['HTTP_USER_AGENT'] self.referrer = request.env['HTTP_REFERER'] end #blogs_controller.rb def create @blog = Blog.new(params[:blog]) @blog.req = request if @blog.save ... I can sort of understand what he is doing. But am confused with the req=(request) line. Any help is appreciated. Thanks

  • Enforcing a coding template in the getters of a class in java

    - by Yoav Schwartz
    Hello, I want to make sure all getters of the classes in a certain package follow a given template. For example, all getters must be of the form: XXX getYYY(){ classLock.lock(); return YYY; finally{ classLock.unlock(); } } Basically, I want that my project will not compile/run unless all getters are of that form. What is the best way to do that? I would prefer a solution that can be used as an Eclipse plugin. Thanks, Yoav

  • PlayDependencyClassLoader does not find application code

    - by jkschneider
    When a third party dependency attempts to load a class defined in a Play application using Class.forName(className, true, Thread.currentThread().getContextClassLoader()); Play will throw a ClassNotFoundException because the context class loader is of type PlayDependencyClassLoader which apparently only contains classes defined in jar dependencies. Caused by: java.lang.RuntimeException: java.lang.ClassNotFoundException: eventstore.Commit at org.mapdb.SerializerPojo.classForName(SerializerPojo.java:96) at org.mapdb.SerializerPojo$1.deserialize(SerializerPojo.java:74) at org.mapdb.SerializerPojo$1.deserialize(SerializerPojo.java:39) This only occurs when Play is started with play run. Starting Play with play start loads the class correctly. It would be a shame to sacrifice the class hot-swapping because of this behavior. Is there a known workaround?

  • Is it naughty to have a large utility file?

    - by banister
    In my C project I have quite a large utils.c file. It is really full of many utilities of different sorts. I feel a bit naughty just stuffing different miscellaneous functions in there. For example it has some utilities related to low level stuff such as a lowercase() function, and it also has some quite sophisticated utilities such as converting to/from different colour formats. My question is, is it very naughty to have such a large utils.c with many different types of utilities in it? Should I break it up into many different kinds of utility files? Such as graphics_utils.c and so on What do you think?

  • How to generate Function caller graphs for other languages?

    - by Jeremy Rudd
    I like the way Doxygen combines with Graphviz dot to generate function caller graphs. I'd like this functionality for other languages as well, apart from the basics that Doxygen supports (C++, C, Java, Objective-C, Python, VHDL, PHP, C#). I'm currently interested in JavaScript, ActionScript 2 and ActionScript 3/Flex but am looking for ways or tools that have a wider language support than Doxygen. Is there any way to get function caller graphs for any other languages?

  • Converting python collaborative filtering code to use Map Reduce

    - by Neil Kodner
    Using Python, I'm computing cosine similarity across items. given event data that represents a purchase (user,item), I have a list of all items 'bought' by my users. Given this input data (user,item) X,1 X,2 Y,1 Y,2 Z,2 Z,3 I build a python dictionary {1: ['X','Y'], 2 : ['X','Y','Z'], 3 : ['Z']} From that dictionary, I generate a bought/not bought matrix, also another dictionary(bnb). {1 : [1,1,0], 2 : [1,1,1], 3 : [0,0,1]} From there, I'm computing similarity between (1,2) by calculating cosine between (1,1,0) and (1,1,1), yielding 0.816496 I'm doing this by: items=[1,2,3] for item in items: for sub in items: if sub >= item: #as to not calculate similarity on the inverse sim = coSim( bnb[item], bnb[sub] ) I think the brute force approach is killing me and it only runs slower as the data gets larger. Using my trusty laptop, this calculation runs for hours when dealing with 8500 users and 3500 items. I'm trying to compute similarity for all items in my dict and it's taking longer than I'd like it to. I think this is a good candidate for MapReduce but I'm having trouble 'thinking' in terms of key/value pairs. Alternatively, is the issue with my approach and not necessarily a candidate for Map Reduce?

  • Trying to use boost lambda, but my code won't compile

    - by hamishmcn
    Hi, I am trying to use boost lambda to avoid having to write trivial functors. For example, I want to use the lambda to access a member of a struct or call a method of a class, eg: #include <vector> #include <utility> #include <algorithm> #include <boost/lambda/lambda.hpp> using namespace std; using namespace boost::lambda; vector< pair<int,int> > vp; vp.push_back( make_pair<int,int>(1,1) ); vp.push_back( make_pair<int,int>(3,2) ); vp.push_back( make_pair<int,int>(2,3) ); sort(vp.begin(), vp.end(), _1.first > _2.first ); When I try and compile this I get the following errors: error C2039: 'first' : is not a member of 'boost::lambda::lambda_functor<T>' with [ T=boost::lambda::placeholder<1> ] error C2039: 'first' : is not a member of 'boost::lambda::lambda_functor<T>' with [ T=boost::lambda::placeholder<2> ] Since vp contains pair<int,int> I thought that _1.first should work. What I am doing wrong?

    - by xelurg
    We have had an interesting competition once, where everyone would write their implementation of hello world program. One requirement was that is should be less than 20 bytes in compiled form. the winner would be the one whose version is the smallest... What would be your solution? :) Platform: 32bit, x86 OS: DOS, Win, GNU/Linux, *BSD Language: Asm, C, or anything else that compiles into binary executable (i.e. no bash scripts and stuff ;)

  • Setting exit status when creating core dump

    - by Zitrax
    For example calling exit(100) would exit the application with status 100, and calling raise(SIGABRT) aborts the application with status 134 while creating a core dump. But what if I want the core dump with status 100 or any other arbitrary value. How can I do that ? I know there are several signals that triggers a core dump, but they seem to have fixed exit statuses.

    I today ask a question, about using Jquery, replace html elements with own values. link text And I use answer, and get a problem. function replaceWithValues not works same in all cases.I call this function two times: 1. btnAddParam click 2. btnCancelEdit click $("#btnAddParam").click(function() { var lastRow = $('#mainTable tr:last'); var rowState = $("#mainTable tr:last>td:first"); replaceWithValues(lastRow, rowState); var htmlToAppend = "<tr bgcolor='#B0B0B0' ><td class='textField' er='editable'><input value='' type='text' /></td><td><textarea cols='40' rows='3' ></textarea></td><td>" + initSelectType(currentID) + "</td><td><input id='txt" + currentID + "3' type='text' class='measureUnit' /></td><td><input type='checkbox' /></td><td></td></tr>"; $("#mainTable").append(htmlToAppend); }); //buttonCancelEdit located in end of row $('#mainTable input:button').unbind().live('click', function() { var row = $(this).closest('tr'); var rowState = $(this).closest('tr').find("td:first"); replaceWithValues(row, rowState); $(this).remove(); }); //do row editable -- replaceWithElements $('#mainTable tr').unbind().live('click', function() { if ($(this).find("td:first").attr("er") == "readable") { var rowState = $(this).closest('tr').find("td:first"); replaceWithElements($(this), rowState); } }); function replaceWithValues(row, er) { if (er.attr("er") == "editable") { var inputElements = $('td > input:text', row); inputElements.each(function() { var value = $(this).val(); $(this).replaceWith(value); }); er.attr("er", "readable"); } } function replaceWithElements(row, er) { if (er.attr("er") == "readable") { var tdinit = $("<td>").attr("er", "editable").addClass("textField"); $('.textField', row).each(function() { var element = tdinit.append($("<input type='text' value="+$.trim($(this).text())+" />")); $(this).empty().replaceWith(element); }); row.find("td:last").append("<input type='button'/>"); //$('.selectField') ... //$('.textAreaField') ... } } $("#btnAddParam").click() function works well. it call function replaceWithValues. I call $('#mainTable tr').unbind().live('click', function() { } to do row editable, and it creates a button in the end of row. After user can click this button and call function $('#mainTable input:button').unbind().live('click', function() {}. and this function call function replaceWithValues. but in this case it doesn't work.

I know that the 'clean' var is called up afterwards to sanitize the fields; I.e. $email = clean($_POST['email']);

  • Quick help refactoring Ruby Class

    - by mplacona
    I've written this class that returns feed updates, but am thinking it can be further improved. It's not glitchy or anything, but as a new ruby developer, I reckon it's always good to improve :-) class FeedManager attr_accessor :feed_object, :update, :new_entries require 'feedtosis' def initialize(feed_url) @feed_object = Feedtosis::Client.new(feed_url) fetch end def fetch @feed_object.fetch end def update @updates = fetch end def updated? @updates.new_entries.count > 0 ? true : false end def new_entries @updates.new_entries end end As you can see, it's quite simple, but the things I'm seeing that aren't quite right are: Whenever I call fetch via terminal, it prints a list with the updates, when it's really supposed return an object. So as an example, in the terminal if I do something like: client = Feedtosis::Client.new('http://stackoverflow.com/feeds') result = client.fetch I then get: <Curl::Easy http://stackoverflow.com/feeds> Which is exactly what I'd expect. However, when doing the same thing with "inniting" class with: FeedManager.new("http://stackoverflow.com/feeds") I'm getting the object returning as an array with all the items on the feed. Sure I'm doing something wrong, so any help refactoring this class will he greatly appreciated. Also, I'd like to see comments about my implementation, as well as any sort of comment to make it better would be welcome. Thanks in advance
