  • GEM Version Requirements Deprecated

    - by Kevin Sylvestre
    When creating a new Rails project using: rails sample Then creating a model using: script/generate model person first_name:string last_name:string Everything is fine. However, if I add any gems to my environment.rb: config.gem "authlogic" And run the same generator, I get the following: /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. The warning just recently appeared (I think), but I would like to fix it if possible. Any hints or similar experiences? Thanks.

  • Minimum Hardware requirements for Android development

    - by vishwanath
    I need information about minimum hardware requirement I need to have better experience in developing Android application. My current configuration is as follows. P4 3.0 GHz, 512 MB of ram. Started with Hello Android development on my machine and experience was sluggish, was using Eclipse Helios for development. Emulator used to take lot of time to start. And running program too. Do I need to upgrade my machine for the development purpose or is there anything else I am missing on my machine(like heavy processing by some other application I might have installed). And If I do need to upgrade, do I need to upgrade my processor too(that counts to new machine actually, which I am not in favor of), or only upgrading RAM will suffice.

  • How Does MVC Handle Missing Data Requirements

    - by Don Bakke
    I'm teaching myself MVC concepts in hopes of applying them to a non-OO/procedural development environment. I am pretty sure I understand simple View - Request - Controller - Request - Model - Response - Controller - Response - View flow. What I am struggling with is understanding more complex scenarios. For instance, let's say I have a shopping cart form with a button for 'Calculate Shipping'. Normally a click on this button will follow the above flow. But what if there is missing data, like the zip code? Should the View verify this first and alert the user before making a 'Calculate Shipping' request? Or should the request be made and the Model returns a notification that critical data is missing? If the latter, does the Controller instruct the View to alert the user? What if I wanted to prompt the user for the missing zip code (perhaps in a popup input display) and then automatically request the 'Calculate Shipping' method again? I suppose this gets into the question of how smart a View ought to be. It seems that MVC has evolved due to richer UI and automation (such as with data-binding) and this muddies the water from a purist MVC perspective. Any thoughts are greatly appreciated.

  • Requirements of an issue/bug tracker

    - by James Brooks
    I've been looking at various issue/bug trackers available on the net. There are some very good ones, but I'm unable to use them as my server does not support Perl/Ruby (for example), I'm not too bothered however because I am able to write code in PHP and as such would prefer something in that language. So I've taken it upon myself to write a custom issue tracker system. As of now it's in early planning stages, and before I continue, I'd like to find out what people need from such an application. My current list of things to add include: Creating/Editing/Deleting issues - both on user and admin level Related issues (similar to that of STO) Admins will be able to create builds/milestones and version control of projects Admins will be able to assign users/groups to a project Roadmap of projects Possible SVN integration with Git? What do you think? There are a couple more things I'd like to add, but I'm sure you'll think of a better way of adding such feature. What would you like to see from an issue tracker?

  • system requirements for Visual Studio 2010

    - by user110182
    My team is currently using VS2005 with the following development PCs that are a few years old: XP, Pentium D 2.8GHz, 2GB RAM. My gut tells me that this is going to be poor hardware for VS2010 development. I am not running VS2010 beta but I am running Blend 3 beta and the performance is bad. Can you point me to anything that I can show my boss to convince him to buy 6 new machines for my team? Edit below after initial answer from Jon: I should have added that my boss wants to upgrade current machines with new hard-drives so I am trying to use this opportunity to take a look forward and see if a HD upgrade is really worth it. This HD upgrade would not just be simple installation of 2nd drive but would replace current drive and would involve backup/restore or reinstallation headaches. There would be the added benefit of 64bit development too, something that we have been talking about.

  • open source project requirements

    - by skidding
    I know it's a very common question, but I don't see a previous one to be asked, since I'm interested in the basic steps, nothing in particular. It's the first time I want to license one of my projects, and it turns out, I don't know much about it. Let's say I want to use the MIT License. Do I just take the definition and paste it into my files? Does it need to be in ALL the files, or just one? or? I don't want any fancy rights so MIT has been recommended to me, do you suggest something else? I'm looking for impartial opinions. Thanks. What other aspects must I take into account? It's PHP, btw.

  • Requirements for connecting to Oracle with JDBC?

    - by Lord Torgamus
    I'm a newbie to Java-related web development, and I can't seem to get a simple program with JDBC working. I'm using off-the-shelf Oracle 10g XE and the Eclipse EE IDE. From the books and web pages I've checked so far, I've narrowed the problem down to either an incorrectly written database URL or a missing JAR file. I'm getting the following error: java.sql.SQLException: No suitable driver found for jdbc:oracle://127.0.0.1:8080 with the following code: import java.sql.*; public class DatabaseTestOne { public static void main(String[] args) { String url = "jdbc:oracle://127.0.0.1:8080"; String username = "HR"; String password = "samplepass"; String sql = "SELECT EMPLOYEE_ID FROM EMPLOYEES WHERE LAST_NAME='King'"; Connection connection; try { connection = DriverManager.getConnection(url, username, password); Statement statement = connection.createStatement(); System.out.println(statement.execute(sql)); connection.close(); } catch (SQLException e) { System.err.println(e); } } } What is the proper format for a database URL, anyways? They're mentioned a lot but I haven't been able to find a description. Thanks! EDIT (the answer): Based on duffymo's answer, I got ojdbc14.jar from http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc_10201.html and dropped it in the Eclipse project's Referenced Libraries. Then I changed the start of the code to ... try { Class.forName("oracle.jdbc.driver.OracleDriver"); } catch (ClassNotFoundException e) { System.err.println(e); } // jdbc:oracle:thin:@<hostname>:<port>:<sid> String url = "jdbc:oracle:thin:@GalacticAC:1521:xe"; ... and it worked.

  • Minimum requirements to use Indefero + SVN

    - by Gnucom
    Hey everyone, I made sure there wasn't a similar discussion before posting but forgive me if I am mistaken. Question: Can I use Indefero - http://www.indefero.net/ - with SVN on a linux server if I do not have any sort of web interface installed for Apache? Instead, I want to use Indefero with SVN by just using the svnserve server. From my readings, I'm not finding this exact situation mentioned anywhere, so I'm doubting if this configuration is possible. Forgive my ignorance; Thanks. :) EDIT: the svnserve server and Indefero installation will be running on the same machine.

  • How to keep Hibernate mapping use under control as requirements grow

    - by David Plumpton
    I've worked on a number of Java web apps where persistence is via Hibernate, and we start off with some central class (e.g. an insurance application) without any time being spent considering how to break things up into manageable chunks. Over time as features are added we add more mappings (rates, clients, addresses, etc.) and then amount of time spent saving and loading an insurance object and everything it connects to grows. In particular you get close to a go-live date and performance testing with larger amounts of data in each table is starting to demonstrate that it's all too slow. Obviously there are a number of ways that we could attempt to partition things up, e.g. map only the client classes for the client CRUD screens, etc., which would have been better to get in place earlier rather than trying to work it in at the end of the dev cycle. I'm just wondering if there are recommendations about ways to handle/mitigate this.

  • Passing a pointer to a function that doesn't match the requirements of the formal parameter

    - by Andreas Grech
    int valid (int x, int y) { return x + y; } int invalid (int x) { return x; } int func (int *f (int, int), int x, int y) { //f is a pointer to a function taking 2 ints and returning an int return f(x, y); } int main () { int val = func(valid, 1, 2), inval = func(invalid, 1, 2); // <- 'invalid' does not match the contract printf("Valid: %d\n", val); printf("Invalid: %d\n", inval); /* Output: * Valid: 3 * Invalid: 1 */ } At the line inval = func(invalid, 1, 2);, why am I not getting a compiler error? If func expects a pointer to a function taking 2 ints and I pass a pointer to a function that takes a single int, why isn't the compiler complaining? Also, since this is happening, what happens to the second parameter y in the invalid function?

  • Zend_Router requirements mismatch

    - by elbicho
    Hello you all: I have two routes that match a url with the same apparent pattern, the difference lies in the $actionRoute, this should only be matched if the variable :action on it equals 'myaction'. If I go to /en/mypage/whatever/myaction it goes as expected through $actionRoute. If I go to /en/mypage/whatever/blahblah it gets rejected by $actionRoute and matched by $genRoute. If I go to /en/mypage/whatever it should be matched by $genRoute but it gets matched by $actionRoute instead throwing and exception because the action noactionAction() does not exist. Don't know what I'm doing wrong, I'd appreciate your help. $genRoute = new Zend_Controller_Router_Route( ':lang/mypage/:var1/:var2', array( 'lang' => '', 'module' => 'mymodule', 'controller' => 'index', 'action' => 'index', 'var1' => 'noone', 'var2' => 'no' ), array( 'var1' => '[a-z\-]+?', 'lang' => '(es|en|fr|de){1}' ) ); $actionRoute = new Zend_Controller_Router_Route( ':lang/mypage/:var1/:action', array( 'lang' => '', 'module' => 'mymodule', 'controller' => 'index', 'action' => 'noaction', 'var1' => 'noone', ), array( 'action' => '(myaction)+?', 'var' => '[a-z\-]+?', 'lang' => '(es|en|fr|de){1}', ) ); $router->addRoute('genroute',$genRoute); $router->addRoute('actionroute',$actionRoute);

  • FLEX: sequence of puppets... 3 requirements

    - by Patrick
    hi, I'm implementing this sequence of puppets in flex: http://dl.dropbox.com/u/72686/itemsSequence.png I want to show the caption when the mouse rolls over the puppet I want the user being able to click on the buttons of the caption (so the caption doesn't have to disappear when I move the mouse out from the user over the caption). I don't want the puppet component to become bigger when the caption is added (it becomes visible), because the puppets have to stay nearby each other, I cannot resize the objects. So.. I need some guidelines to do it. More precisely: 1) Should I add the components in MXML or pure actionscript ? 2) If I use MXML, should I add also the caption to the flex model, and make it invisible and then change the value with actionscript ? What's the common way to implement it ? thanks

    You can just have user stories somehow the functionality of the program has to be documented. Do you end up with a specifications document with scrum? If you do do you end up assigning time to do this onto the task?

  • Activerecord default accessors & unusual requirements

    - by JP
    I have an ActiveRecord::Base class which needs to have a field that is automatically generated when a new instance is made. How should I go about doing this? By defining an initialize function? class Thing < ActiveRecord::Base # 'special' (integer) needs to be set to lowest unused number (above 0) # considering that random rows will be removed via other processes end This is as far as I've got! Any ideas?

  • How to modify CSS when requirements change?

    - by DaveDev
    Suppose I'm given the requiremnt to geneate a few pages that have tables on them. The original requirement is for all tables to be 500px. I'd write my CSS as follows: table { width: 500px; } That will apply accross the board for all tables. Now, what if they change the requirment so that some tables are 600px. What's the best way to modify the CSS? Should I give the tables classes so table.SizeOne { width: 500px; } table.SizeTwo { width: 600px; } Or is there a better way for me to deal with changes like this?

  • Software Requirement Specifications for Web Applications

    - by illuminatedtiger
    Hi guys, I'm looking for some guidance/books to read when it comes to creating a software requirement specification for a web application. For inspiration I have read some spec documents for desktop based applications. The documents I have read capture a systems functional requirements in use cases which tend to be rather data oriented with use cases centered around the various CRUD operations the application is intended to perform. I like this structure however I'm finding it rather difficult to marry it to what my web application needs to do, mostly reading data as opposed to manipulating it. I've had a go at writing some use cases however they all tend to boil down to "Search for item", "Change view of search results" or "User selects facet to refine search results". This doesn't sound quite right to me and makes me wonder if I'm going about this the right way. Are there planning differences between web based and desktop based applications?
