  • Getting started with learning the Rails source

    - by japancheese
    Hello, I've been using Ruby on Rails for many projects lately, and I thought it would be interesting to take a look at the Rails source and really see how things operate underneath. I think it'd be a great learning experience and would probably enhance the way I code Rails apps all the more. Does anyone have any tips on how to get started? And where within the Rails source does an application begin to be executed? Perhaps if I started there, I could see how everything is loaded and works in general.

  • Useful design patterns when dealing with spring 3 controllers

    - by Mat Banik
    Recently I was overlooking my controllers and they are bit of mess. I'd like to organize they way I set returning views Do more elegant mesageSource massaging back to the users and account for i18n Security checking, what user can access an what they can't Consistent way of calling the service layer And somehow bring consistency to the debugging lines. Do better job with error handling and serving it to the user. I'm already on mission to do security logging with AOP :) I'm just looking for patterns I could implement to help me to do all of the above. Or just some general advice in case no patterns apply, or advice on something I didn't mention but is common practice.

  • starting 64 Bit Windows Application Development

    - by user173438
    I intend to start writing a 64 Bit Scientific Computing Application (signal processing) for Windows using Microsoft Visual Studio 2008. What should I have ready as far as a development platform is concerned? How would it be different from 32 Bit development? What could be the porting issues for a 32 Bit version that I already have (ok - this might too early to ask.. even before I start compiling)? As you might have guessed, I am looking for general directions. All pointers would be much appreciated! :) Thanks in advance..

  • Accessing typedef from the instance

    - by piotr
    As in stl containers, why can't we access a typedef inside the class from the class instance? Is there a particular insight into this? When value_type was a template parameter it could help making more general code if there wasn't the need to specify the template parameters as in vector::value_type Example: class T { public: typedef int value_type; value_type i; }; T t; T::value_type i; // ok t.value_type i; // won't work

  • Multiple developers on a Titanium project

    - by Cybear
    I'm making an iPhone app with Appcelerator Titanium and I want to share the source code with a few more programmers. I will use a SCM repository which at some point might be open to the general public. Now my question is, are there any files which I should not commit to the repository? In project root I can tell that tiapp.xml and mainfest are telling the app GUID, is there any reason for me to keep that private? (this value is also shown many places in the build/ folder) I've added everything in the Resources/ folder. If I skip the build/iphone/build/ folder, will developers still be able to build the project? Side question - When another programmer downloads this code, it seems to me that (s)he has to have the same directory structure as I do? Any workarounds for this?

  • tinyMce reloading data with html tags

    - by Arunraj Chandran
    I'm having issue with TinyMCE. After saving the contents of the editor and redisplaying it all the HTML tags are visible. This is how I'm initializing the editor: // Tinymce Config tinyMCE.init({ // General options mode : "specific_textareas", editor_selector : "mceEditor", language : "<?php echo $tinyMceLang?>", setup : function(ed) { ed.onActivate.add(tinyOnEdit); }, theme : "advanced", plugins : "table", // Theme options theme_advanced_buttons1 : "bold,italic,underline,strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,fontsizeselect,|,forecolor,backcolor,|,table,row_before,row_after,delete_row,col_before,col_after,delete_col,code", theme_advanced_buttons2 : "", theme_advanced_buttons3 : "", theme_advanced_buttons4 : "", theme_advanced_toolbar_location : "top", theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : "bottom", theme_advanced_path : false, theme_advanced_resizing : true, convert_fonts_to_spans : true, //font_size_style_values : "0.7em,0.8em,1em,1.2em,1.5em,2em,3em", //font_size_style_values : "8pt,10pt,12pt,14pt,18pt,24pt,36pt", // content CSS (should be your site CSS) content_css : "/css/tiny_content.css" }); if i paste a content like this (With HTML tags): "testing tinymce contents" redisplayed as : "testing tinymce contents" but excepted result is : testing tinymce contents (Text with red color)(Not allowing html tags)

  • Adding search for a private website

    - by Vitor Py
    I have a login-protected website. It's an internal application and it's not avaiable to the general public hence it's not indexed by any search engine. My application is developed on the Google App Engine. I would like to add a search engine but obviously without the need to public index it. There's any solution avaiable from Google/Bing/Others for a situation like this? Have you done this before? What solution did you chose and what are yours results?

  • When to release the UIImage ?

    - by ragnarius
    I use the following code to draw a subimage UIImage* subIm = getSubImage( large, rect ); [subIm drawInRect:self.bounds]; where getSubImage is defined as follows UIImage* getSubImage(UIImage* uim, CGRect rc){ CGImageRef imref = CGImageCreateWithImageInRect(uim.CGImage, rc); UIImage* sub = [UIImage imageWithCGImage:imref]; CGImageRelease(imref); NSLog(@"subimage retainCount=%d", [sub retainCount]); // is 1 return sub; }//getSubImage Is the code correct? Is it safe to "CGImageRelease" imref? Has sub "CGImageRetained" imref? Should I release subIm (I get an error if I do)? Is subIm contained in the autorelease-pool, and , if so, how do I know this? In general, can one check if an object is contained in the autorelease pool (for debugging purpose)?

  • Voice Control iOS

    - by Marc Tanis
    I would like to build a simple reader app for the iPad 2 that would allow users to navigate/read via voice controls. The app would allow the user to enter a mode where the microphone was live and listened for predefined keywords like 'down', 'up', 'next', 'back', 'home', etc. I don't want to reinvent the wheel on this so I'm just wondering first, if someone has done this already and if not, are there any good tutorials or SDKs available to help with recording someone's voice, and then comparing future output to see if it matches, or just dealing with the microphone in general?

  • SQL trigger for audit table question

    - by mattgcon
    I am writing a trigger to audit updates and deletes in tables. I am using SQL Server 2008 My questions are, Is there a way to find out what action is being taken on a record without going through the selection phase of the deleted and inserted tables? Another question is, if the record is being deleted, how do I record within the audit table the user that is performing the delete. (NOTE: the user connected to the database is a general connection string with a set user, I need the user who is logged into either a web app or a windows app) Please help?

  • BlackBerry project version number

    - by Seva Alekseyev
    I have a BlackBerry Java project in Eclipse. It has version number written down in four different spots: in the project properties, under "BlackBerry Project Settings/General" in the JAD file, under MIDlet-1 in the JAD file, under MIDlet-Version in the ALX file, under <version> And they seem uncorrelated. Changing either of these affects none of the rest. The third one is what the users sees during over-the-air setup and under Options/Advanced. Questions - why do we need all these? Are there contexts where numbers 1, 2, 4 come up? It's my understanding that the ALX is generated during compilation - where does the version # come from? Is there a way to learn at least one of those programmatically (without signing the app)?

  • ASP.NET Forms automation/serialization/binding

    - by creo
    I need to implement many forms in ASP.NET application (for IRS mostly). There are will be a lot of standard controls for each form (textboxes, dropdowns, checkboxes, radio). And business entity assigned to each. What's the best solution to automate this process? I need to: Have layout stored in DB (in XML). Layout must support several columns, tabbed interface Automatically bind business object values to the form Automatically read form values and write to business object Must support automatic validation Some basic workflows support would be good I used to work with TFS and saw how they implemented WorkItem templates (.wit files). In general this is all I need. But what framework did they build it on? How can I utilize this solution? I know about Dynamic Data only: http://www.asp.net/dynamicdata

  • Python IDLE freezes

    - by ooboo
    This is absolutely frustrating, but I am not sure if the following is an issue only on my machine or with IDLE in general. When attempting to print a long list in the shell, and that could happen by accident while debugging, the program crushes and you have to restart it manually. Even worse, if you have a few editor windows open, it always spawns a few sub-processes, and each of these has to be manually shut down from the task manager. Is there any way to avoid that? I am using Python 3, by the way.

  • How to protect HtmlHelper code in MVC controls

    - by Oats
    I am writing a custom mvc control (commercial), and all of the control's code lives in the custom htmlhelper code that i will have to distribute to the user. I am ok with this for my commercial license sale, but for evaluating the controls, if i give out the htmlhelper code locally for my potential customers to evaluate, the user can simply "get" all the code and hence he may never buy it since he's got teh control code. How do i protect my htmlhelper code while somebody is evaluation my cusotm mvc controls? Is this a general problem or (I wish) i am missing something here? Thanks.

  • What's the best way of using a pair (triple, etc) of values as one value in C#?

    - by Yacoder
    That is, I'd like to have a tuple of values. The use case on my mind: Dictionary<Pair<string, int>, object> or Dictionary<Triple<string, int, int>, object> Are there built-in types like Pair or Triple? Or what's the best way of implementing it? Update There are some general-purpose tuples implementations described in the answers, but for tuples used as keys in dictionaries you should additionaly verify correct calculation of the hash code. Some more info on that in another question. Update 2 I guess it is also worth reminding, that when you use some value as a key in dictionary, it should be immutable.

  • Where is the best place to put <script> tags in HTML markup?

    - by mipadi
    When embedding JavaScript in an HTML document, where is the best place to put the <script> tags and included JavaScript? I seem to recall that you are not supposed to place these in the <head> section, but placing at the beginning of the <body> section is bad, too, since the JavaScript will have to be parsed before the page is rendered completely (or something like that). This seems to leave the end of the <body> section as a logical place for <script> tags. So, where is the best place to put the <script> tags? (This question references this question, in which it was suggested that JavaScript function calls should be moved from <a> tags to <script> tags. I'm specifically using JQuery, but more general answers are also appropriate.)

  • Feature categories for a social network

    - by mafutrct
    Not sure if this question belongs on SO. Anyway, please let me try to clarify the issue. I'm currently planning a social program. It's basically a chat server with the major additional ability to play games. I'd like to create categories of features that are offered to users. My question is, are there any useful standard feature categories? Does not have to be specific to my case, I'm interested in the general case as well. Just to give you an idea of what I'm thinking: functional e.g. play games social e.g. chatting operational e.g. 24/7 service availability I'm entirely unsure if this is the right place to ask, if you know of any better site to ask please don't hesitate to add a comment.

  • How to use gems not in a Gemfile when working with bundler?

    - by arikfr
    When using bundler with a project in general and Rails specifically, you have access only to gems defined in your Gemfile. While this makes sense, it can be limiting. Mostly I find it limiting when I want to use a certain RSpec formatter that the rest of the team doesn't use. Unless it's in the Gemfile, it isn't accessible. Any way around it or I have to add it to Gemfile? Update: my problem wasn't Bundler but Spork. When running RSpec without Spork I had no problem of using whatever formatter I wanted.

  • How does the " is " operator work internally

    - by JDMX
    I want to compare the type of an object to a type to see if they are the same. I do not have the object, just the type of the object. I can do type1 == type2 and get general equality I can have a recursive loop where I repeat the above step for type1.BaseType until the BaseType is null. I can do type1.GetInterface( type2.FullName ) != null to check if type2 is an interface of type1 If I put it all together, I get if ( type2.IsInterface ) return type1.GetInterface( type2.FullName ) != null; while ( type1 != null ) { if ( type1 == type2 ) return true; type1 = type1.BaseType; } return false; Is that all the is keyword is. I cannot find the right keyword to plug into the Reflector search to find the function and a google search on "is" was not really helpful

  • Function testing on Netbeans 6.8

    - by ron
    While not a torrent, but some articles can be found on the net about function testing (particularly http://blogs.sun.com/geertjan/entry/gui_testing_on_the_netbeans). However the tools mentioned by them do not seem to be maintained, or don't have a plugin working with the most recent version of Netbeans (6.8). Do you have any function test setup for GUI? What is your level of integration into the development process (IDE integration, ant, etc). Additional candy is that Netbeans is not only the IDE, but the GUI app is also developed for Netbeans 6.8 Platform (so I'm mainly interested in GUI testing NB-platform apps, but tips for any Swing apps in general would be a help too).

What is general rule of thumb on how to use callback in anyPHP built-in function ?

  • Content pulled in via jQuery AJAX is not associating with previous functions

    - by Jarsen
    I'm using the jquery .load() function to pull in data to populate a div with. The content I'm pulling in has CSS selectors that should match up with jQuery click functions I've written. However, when I load in the data, although the correct CSS selectors are there, when I click on areas that should invoke a response from jQuery, nothing happens. Do I need to do some sort of reload? Here's the code I've got for the jQuery AJAX: $(document).ready(function() { // AJAX functionality for drupal nodes $(".ajax_node").click(function() { var ajax_src = $(this).attr("href"); // we're gonna load the href // empty target div and load in content // the space in the string before the #id is necessary $("#ajax_area").empty().load(ajax_src + " #ajax_wrapper"); return false; // stops the link from following through }); // General AJAX fucntionality $(".ajax").click(function() { var ajax_src = $(this).attr("href"); $("#ajax_area").empty().load(ajax_src); return false; }); });
