• What is the best place to store globals in Rails app?

  - by Nick Gorbikoff

  Hello. I was wondering if there is the best practice on where to store global settings in a rails app. What I mean by that is i.e: I have a few globals defined that may change, but not likely and it seems inappropriate to store them in DB since they are used so much. For instance I have SYSTEM_EMAIL & SYSTEM_EMAIL_SIGNATURE & SYSTEM_STORAGE_ROOT. Right now I keep them in environment.rb, but I'm not sure if this is the right palce to store them. Thank you

  - by Namratha

  Hi, What i need to do is as follows: I have a bigloo scheme program (*.scm), then using the bigloo frameworks jvm a class file is generated. I want to use this .class file from a .java file. That is, i need to import this(.class) file as i want to use some functions defined in the scheme file which is now a .class file. How do i do it in Eclipse? i have created two packages one for java and one for the .class file. Then i import the package containing the .class file. But i am not able to use the function in the .class file in the .java file. Are there any settings to be done? Please let me know how this can be done.

• Are unspecified and undefined behavior required to be consistent between compiles?

  - by sharptooth

  Let's pretend my program contains a specific construct the C++ Standard states to be unspecified behavior. This basically means the implementation has to do something reasonable but is allowed not to document it. But is the implementation required to produce the same behavior every time it compiles a specific construct with unspecified behavior or is it allowed to produce different behavior in different compiles? What about undefined behavior? Let's pretend my program contains a construct that is UB according to the Standard. The implementation is allowed to exhibit any behavior. But can this behavior differ between compiles of the same program on the same compiler with same settings in the same environment? In other words, if I dereference a null pointer on line 78 in file X.cpp and the implementation formats the drive in such case does it mean that it will do the same after the program is recompiled?

• BlackBerry - Multiple Screens or Single Screen with Content Manager?

  - by Max Gontar

  Hi! I've seen projects which use many screens each one for different layout and functionality. I've seen projects with only one screen (like wizard workflow) where content is changed on user interaction (and this seems to be logical to use single screen in wizards). But also I've seen projects (apps like game or messenger or phone settings utility) which use single screen for different functionalities. I can see such advantages of having single screen in app: keep same decoration design and menu or toolbar (which may be also achieved with inheritance) keep single screen in ui stack (which may be achieved by pop/push screen) easy to handle data over application Can you tell other advantages/disadvantages of single screen app? When its better to use this approach? Thank you!

• Within SSIS - Is it possible to deploy one package multiple times in the same instance and set diffe

  - by Matt

  In my environment my Dev and QA Database Instances are on the same server. I would like to deploy the same package (or different versions of the package) into SSIS and set the filter to select different rows in the Config table. Is this possible? This is SQL 2005. For the sake of this question lets say I have one variable, which is a directory path. I would like to have these variables in the table twice (with different Filters applied (Dev and QA) as below (simplified) . . . Filter / Variable Value / Variable Name Dev / c:\data\dev / FilePath QA / c:\data\qa / FilePath Do I need to apply a change within the settings of the package in SSIS or is it changed on the job step within Agent? Any help would be appreciated.

• String.Format with NumberGroupSeparator outputting 0xa0 not comma

  - by andrevdm

  I'm seeing strange results when doing a string.Format( "C" ); E.g. double val = 123456.78; Console.WriteLine( val.ToString( "C" ) ); This prints the thousand separator as 0xa0 rather than a comma (0x2c). I get the same result if I use string.Format( "{0:0,0.00}", 1234567.12D ); Here is the full output R 123ÿ456,78 52333A333233 201230456C78 My regional settings are English (South African) and I'm getting the same result on multiple machines. Any ideas? Thanks.

• AdMob won't load programmatically

  - by scottbot95

  I'm need to include ads into my app and I have a settings option to disable ads. so I need to load the ad in code. I copied the code from google to handle that and when I set ads:loadAdOnCreate to true, it works just fine. But if I set it to false and add the two lines AdView adView = (AdView)this.findViewById(R.id.ad); adView.loadAd(new AdRequest()); The ads stop displaying. If I look at log cat, it shows that it is receiving an ad and trying to display it. However it won't actually display on screen. Help?

• A way to search form table in MySQL database.

  - by Eugene

  I looked for a way to scan database for a specific table. For example i have: Database: system_ultimate Table: system_settings And let us say, that one doesn't know precise name of the table. He only knows, that it is some how connected to word settings. How could he search for that table name then? I understand, that usually people who develop know, what they develop, but I'm trying to get hang of MVC and I'm trying to stay as far away as possible from direct communication with table using the name. I know, that to see all tables I could use SHOW TABLES;

• replay in django + apcahce + mod_wsgi ??

  - by Adam

  I have a simple django page that has a counter on it. I use Apache2 and mod_wsgi to serve it. First, when I enter this page, the counter shows 0, as it should. The second time when I enter the page the counter shows 1 - again, it is the right behavior. The problem begins now, cause when I enter this page the third time, I get 0 again. When I refresh it goes between 0, and 1, clearly using some cache or so. If I wait for some time and then try again, it will show 2, and 3, but will be stuck with those values, till this cache or whatever it is will be flushed, and then the counter continues. Does somebody knows how I can get it work right (the real scenario deals with getting data from the DB, but the problems with this strange cache are the same). BTW, I don't have any caching engine set in my django settings.

• On which Windows versions and configurations does my C++ app run?

  - by saas

  I've built a C++ application using MSVC 2010, default compile settings (note: Using "Multithreaded" instead of "Multithreaded DLL" to avoid the Microsoft C++ runtime being needed). I used only the STL and a few, old functions from the Win32 API (Windows.h). Where will my app run? (98-7?) Can the be any differences on how my app works on different PCs? As said: It's only a simple console app. I'd be glad if you could add some additional information if you have it!

• Notice Undefined index url

  - by user1906992

  I'm doing youtube mvc tutorial http://www.youtube.com/watch?v=Aw28-krO7ZM and have stopped on the best first step: my index.php file: <?php $url = $_GET['url']; require 'controllers/' . $url . '.php'; My .htaccess file: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-l RewriteRule ^(.+)$ index.php?url=$1 [QSA,L] so, the question is next: when i go on any other url except 'index' it works good. So what's wrong with 'index' url? Notice: Undefined index: url in /var/www/sadman/index.php on line 2 Warning: require(controllers/.php) [function.require]: failed to open stream: No such file or directory in /var/www/sadman/index.php on line 4 Btw, i have LAMP, and i think my settings are wright.

• CSS Rule Priorities

  - by Antilogic

  Given the following mark-up... <div id="Header"> <a href="#" class="Highlight">foo</a> </div> And the following stylesheet... /******************Exceptions******************/ #Footer, #Header, #Footer a, #Header a { color: #f8f8f8; } /******************Classes******************/ .Highlight, a.Highlight { color: #B1D355; } .Notification, a.Notification { color: Red; } Why is my link still off-white (F8F8F8) rather than green (B1D355)? Shouldn't using the class Highlight override the color settings for Header and Footer since it comes after their declarations?

• Can I override a group policy setting as a machine admin?

  - by Max

  Group policy prevents several configuration settings on my Windows 7 / Vista machines. Since my domain account is a member of the local Administrators group on these boxes, is there still a way to override them locally? For instance, GP prevents changing the power management option "Turn off the display" (even changing it from cmd fails: POWERCFG -X -monitor-timeout-ac 60 = "An unexpected error condition has occurred. Unable to perform operation. You may not have permission to perform this operation.") Even when logging on with a local account and not the domain account, it's not possible to change the setting anymore ..

• ColdFusion debugging output in my Ajax

  - by cf_PhillipSenn

  If I turn off "Enable Request Debugging Output", the 3rd option under the Debug Output Settings, then I no longer get debug info in my $.ajax call to a cfc with access="remote". That's good, but I'd like to keep it turned on for all my other programs and turn it off programatically for this one exception. I put <cfsetting showdebugoutput="false"> at the top of my Index.cfm, but that didn't turn off the debug output coming from the cfc. Oh wait. Never mind. I had to put the in the function rather than in Index.cfm.

• Arrays and application data

  - by s0mmer

  Hello everyone, At the moment i'm making an application where it is possible to make profiles with different settings. Which datatypes would you recommend me saving these information in? I have a table which is showing the profile name and the version number. But for each profile there need to be stored more information. Therefore the idea i'm working on have 2 arrays. 1 for all the profile information and 1 who is being made when loading the information. The second array is the one going to be showed in the table. Because the table doesnt show all the stored information. .. but this seems kinda stupid. Is there a more suitable method for saving the information in like 1 array, and just pass part of the data to the tableview?

• Ways to Unit Test Oauth for different services in ruby?

  - by viatropos

  Are there any best practices in writing unit tests when 90% of the time I'm building the Oauth connecting class, I need to actually be logging into the remote service? I am building a rubygem that logs in to Twitter/Google/MySpace, etc., and the hardest part is making sure I have the settings right for that particular provider, and I would like to write tests for that. Is there a recommended way to do that? If I did mocks or stubs, I'd still have to spend that 90% of the time figuring out how to use the service, and would end up writing tests after the fact instead of before...

• wordpress not properly functioning anymore after moving it to another domain

  - by Andy

  Hi, I followed the instructions on http://codex.wordpress.org/Moving_WordPress under 'Moving WordPress to a New Server' and 'If You Want Your Old Blog To Still Work' So I made a copy of everything marked is as old, then changed the domain under the WP settings, made a new copy. And now put the first copy back but when I go to the login page I can reach it, but it's without the usual markup as first. It's all skinned out. After I login, worpress uses the new domain instead of the old domain which the old copy of wordpress used!! what went wrong?? thanks.

• require user to login in at login screen before giving access to iPhone app that accesses secure web

  - by MikeN

  On iPhone, how do I show a login screen to get username and password before giving access to iPhone app? Also, does the iPhone store a cookie to the secure website like a web browser? I was thinking of giving users to my website a long API key to store in the settings of their iPhone instead of asking them to login with a username/password (seems to be the Slicehost iPhone app approach.) Which is the best way to get a user to login securely? I have full control over the design of the iPhone app and website so have a lot of flexibility.

• In Xcode, the main controller is hopelessly misconfigured. What are the steps I can take to fix all

  - by MikeN

  Somehow the main .xib file for my iphone project got deleted. I created a replacement .xib file, but the properties are not setup correctly for the MainWindow to load this one. I don't understand and am hopelessly confused about any of the properties and which ones may or may not be sent. What are the X properties that all need to be set to have this work correctly? I've checked all of these, but there appear to be others: 1) The app delegate for the project is set to the new ControllerUI class. 2) The MainWindow.xib shows the correct .xib file as being loaded from (it has a link in its UI to the .xib file that should be loaded on project run. There appear to be other settings that have to be changed and I can't find them. Is there a way in XCode to recreate the MainWindow.xib file? Should I just create a new project and move all of the other files into it?

• Eclipse C++ on WinXP - Type `::iterator' has not been declared

  - by redwolfe

  I'm new to C++/Eclipse. I'm trying to get it working to get a new perspective on a problem with a program I wrote in DevCPP. The program is simple and builds fine in DevCPP. In Eclipse, I get hundreds of errors like the one above. I assume the compiler can't see my include files. I've checked that the project settings - GCC C++ compiler - directories contains the location for my include files (D:\MinGW\include\c++\3.4.5). I've prowled around and tried to change 'Discovery Options' to 'GCC C++ Compiler' from 'GCC C Compiler' but it keeps changing back. I guess this is not the problem. Any help would be very welcome. I'm on a tight deadline with many interruptions and this is cracking me up.
