  • should/could i use ruby-on-rails 3 for my next project?

    - by fayer
    im new to ruby and ruby on rails. im on a new project and would really like to code in ruby. of course u have to use a framework like RoR for web development. so my question is if i should/could use ruby-on-rails 3 for this new project that i will start with in 2-3 weeks from now. are there tutorials for it? is it stable enough? well tested? cause one thing when entering something totally new, you need tutorials and books that teach you how to use it. i guess there arent a lot of sources for this information so maybe its better for me to use the latest stable version? what do you think? thanks

  • DirectSound affects system volume on WinXP

    - by Anton
    Hello guys, I'm currently developing an audio engine that is used in voice network chat software. Everything is working fine - capture/playback/mixing channels. The problem is in using it under Windows XP. I've been getting user reports with information that their global system volume is set to zero after launching the application. I'm assuming that happens because of WaveOut/DSound conflict. How can I force DSound not to affect system volume? Playback device is initialized: DirectSoundCreate8(&GUID, &pAudio, NULL); and: pAudio-SetCooperativeLevel(parentWnd, DSSCL_PRIORITY); I'm currently not able to debug the application, cause I'm using Vista and everything is OK. Hope you can help me with this issue! Thanks a Lot! Regards, Anton.

  • GNU Smalltalk API?

    - by Zachary
    I have recently been learning Smalltalk, mainly by going through the tutorial at gnu.org. While it has been really helpful and I have learned a lot, I would really like an extensive smalltalk API where I could view all of the built in objects and which messages they can receive, and what they will do with those messages. The manual has a list of all of the built in objects, but doesn't really explain anything about them. Some are obvious, like an Array, but I still don't know what all the messages are an Array understands. There is a link to a 'class reference' here, which is generated by Smalltalk, but the link is broken. I was wondering if anyone knows of something like this hosted elsewhere, or could point me towards a similar resource.

  • regex : how to eliminiate urls ending with .dtd

    - by dorelal
    This is JavaScript regex. regex = /(http:\/\/[^\s]*)/g; text = "I have http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd and I like http://google.com a lot"; matches = text.match(regex); console.log(matches); I get both the urls in the result. However I want to eliminate all the urls ending with .dtd . How do I do that? Note that I am saying ending with .dtd should be removed. It means a url like http://a.dtd.google.com should pass .

  • ruby / rails / mysql performance degraded on Snow Leopard

    - by adamaig
    I've burned a bunch of hours on this. I'm not having problems getting things to build, but I am seeing that my test suite runs about 2x slower than when I was on OS X 10.5.x . I've spent a lot of time playing around with different optimization settings (learning to avoid homebrew's llvm-gcc compilation). I've just learned that I needed to tweaks /Library/Preferences/SystemConfiguration/com.apple.Boot.plist in order to get the kernel to boot in 64 bit mode. However, my rails app is still running a bit slower than before, even after warming up the mysql server. So what performance tweaks might i need to look into? Right now the stock ruby 1.8.7 runs faster than 1.9.1 for some things, and I'd really like to know if there is anything I should be looking for. All my dev software has been compiled for x86_64, mysql with -O2 optimization, using regular gcc (not llvm-gcc).

  • building a backend for generating webquests with rails

    - by buk
    hello, i want to learn rails and as a project to learn rails i came across webquests. what a webquest is is clearly written here1 and this is a example how a webquest look like. i started with script/generate nifty_scaffold introduction index and repeat this for every section like task , Process, Evaluation and so on. but i dont think thats the right way because i have a lot of code for the same thing. on the other side i am more flexible on designing views or controllers instead of having only one controller foer all pages. i am not asking here to get code. i am asking who to "build" such a backend where you can click on "New Webquest" a form comes up and you can enter all the text who belongs to the topic. maybee i can add some drawings later. i hope anyone can show me how to do that. or post me some links or some rtfms :D regards, buk

  • IIS URL Rewriting for all Inbound URLs?

    - by Rob Burke
    Hopefully a simple question although one I have found impossible to answer myself using the Googles! I have a website on IIS with the URL http://www.contoso.com/ which points to C:\www\public\ There has been a forced directory restructure so now all of the data (Default.aspx, Product.aspx, etc.) that originally resided in C:\www\public\ now resides in C:\www\public\en\ie\ - however, the IIS website document root is still C:\www\public\ So, essentially, I have a lot of inbound links to http://www.contoso.com/Product.aspx?id=1 (etc.) which are now returning 404 errors - the correct link is now http://www.contoso.com/en/ie/Product.aspx?id=1 Please consider that I can make no changes to the directory structure or the IIS document root... so must solve this issue using URL rewriting. Is it possible to capture all requests to contoso.com/* and rewrite them to contoso.com/en/ie/* ??

  • Xpages - Get number of active sessions

    - by Jairo
    How do I get the number of active sessions in Xpage. I'm trying to use managed beans but it just returns a weird string. Here's the simple code: import javax.servlet.http.HttpSessionEvent; import javax.servlet.http.HttpSessionListener; public class SessionCounterListener implements HttpSessionListener { private static int totalActiveSessions; public static int getTotalActiveSessions(){ return totalActiveSessions | 0; } public void sessionCreated(HttpSessionEvent arg0) { totalActiveSessions++; System.out.println("sessionCreated - add one session into counter"); } public void sessionDestroyed(HttpSessionEvent arg0) { totalActiveSessions--; System.out.println("sessionDestroyed - deduct one session from counter"); } } I got this from here. But when I call SessionCounterListener.getTotalActiveSessions(), it only returns a weird string, example com.gs3.beans.SessionCounterListener@46c446c4. Please help me. Thanks a lot!

  • A PHP design pattern for the model part [PHP Zend Framework]

    - by Matthieu
    I have a PHP MVC application using Zend Framework. As presented in the quickstart, I use 3 layers for the model part : Model (business logic) Data mapper Table data gateway (or data access object, i.e. one class per SQL table) The model is UML designed and totally independent of the DB. My problem is : I can't have multiple instances of the same "instance/record". For example : if I get, for example, the user "Chuck Norris" with id=5, this will create a new model instance wich members will be filled by the data mapper (the data mapper query the table data gateway that query the DB). Then, if I change the name to "Duck Norras", don't save it in DB right away, and re-load the same user in another variable, I have "synchronisation" problems... (different instances for the same "record") Right now, I use the Multiton pattern : like Singleton, but multiple instances indexed by a key (wich is the user ID in our example). But this is complicating my developpement a lot, and my testings too. How to do it right ?

  • Sparse O(1) array with indices being consecutive products

    - by Kos
    Hello, I'd like to pre-calculate an array of values of some unary function f. I know that I'll only need the values for f(x) where x is of the form of a*b, where both a and b are integers in range 0..N. The obvious time-optimized choice is just to make an array of size N*N and just pre-calculate just the elements which I'm going to read later. For f(a*b), I'd just check and set tab[a*b]. This is the fastest method possible - however, this is going to take a lot of space as there are lots of indices in this array (starting with N+1) which will never by touched. Another solution is to make a simple tree map... but this slows down the lookup itself very heavily by introducing lots of branches. No. I wonder - is there any solution to make such an array less sparse and smaller, but still quick branchless O(1) in lookup?

  • Best practices for combining Lucene.NET and a relational database?

    - by FlySwat
    I'm working on a project where I will have a LOT of data, and it will be searchable by several forms that are very efficiently expressed as SQL Queries, but it also needs to be searched via natural language processing. My plan is to build an index using Lucene for this form of search. My question is that if I do this, and perform a search, Lucene will then return the ID's of matching documents in the index, I then have to lookup these entities from the relational database. This could be done in two ways (That I can think of so far): N amount of queries (Horrible) Pass all the ID's to a stored procedure at once (Perhaps as a comma delimited parameter). This has the downside of being limited to the max parameter size, and the slow performance of a UDF to split the string into a temporary table. I'm almost tempted to mirror everything into lucenes index, so that I can periodicly generate the index from the backing store, but only need to access it for the frontend. Advice?

  • WPF binding and pointers

    - by Eran
    hey guys, I have a WPF application that contains windows with few user controls and Coordinator object. the window and all its user controls pointing to an object, which instace is in the Coordinator, by thier DataContext. the problem is that I want to change this object (e.g. create new object()) in the Coordinator but I want all the dataContexts to point to the new object. I tried to send the object by ref to the window constructor but it didn't help. any idea about how can I rewrite the memory location that all pointers are pointing to? (I don't want to repalce the properties in object since its a lot of work nor to use a middle object that points to the replaced object) Thanks Eran

  • How do I set scons system include path

    - by Michael Anderson
    Using scons I can easily set my include paths: env.Append( CPPPATH=['foo'] ) This passes the flag -Ifoo to gcc However I'm trying to compile with a lot of warnings enabled. In particular with env.Append( CPPFLAGS=['-Werror', '-Wall', '-Wextra'] ) which dies horribly on certain boost includes ... I can fix this by adding the boost includes to the system include path rather than the include path as gcc treats system includes differently. So what I need to get passed to gcc instead of -Ifoo is -isystem foo I guess I could do this with the CPPFLAGS variable, but was wondering if there was a better solution built into scons.

  • Simple question about image_graphviz

    - by garcon1986
    Hello, I'm trying to display the example of image_graphviz Here, but it doesn't display anything in my page. Here is my page: test.php <?php require_once 'Image/GraphViz.php'; $gv = new Image_GraphViz(); $gv->addEdge(array('wake up' => 'visit bathroom')); $gv->addEdge(array('visit bathroom' => 'make coffee')); $gv->image(); ?> I think there is something wrong with the path, and then i use the absolute path which is "C:/wamp/bin/php/php5.3.0/PEAR/Image/GraphViz.php". But it doesn't work too. Is there something wrong? Do you have any idea? Thanks a lot.

  • Microsoft SQL 2005 - using the modulo operator

    - by cc0
    So I have a silly problem, I have not used much MSSQL before, or any SQL for that matter. I basically have a minor mathematical problem that I need solved, and I thought modulo would be good. I have a number of dates in the database, but I need them be rounded off to the closest [dynamic integer] (could be anything from 0 to 5000000) which will be input as a parameter each time this query is called. So I thought I'd use modulo to find the remainder, then subtract that remainder from the date. If there is a better way, or an integrated function, please let me know! What would be the syntax for that? I've tried a lot of things, but I keep getting error messages like integers/floats/decimals can't be used with the modulo operators. I tried casting to all kinds of numeric datatypes. Any help would be appreciated.

  • Python and App Engine project structure

    - by Joel
    Hello, I am relatively new to python and app engine, and I just finished my first project. It consists of several *.py files (usually py file for every page on the site) and respectively temple files for each py file. In addition, I have one big PY file that has many functions that are common to a lot of pages, in I also declared the classes of db.Model (that is the datastore kinds). My question is what is the convention (if there is one) of arranging these files. If I create a model.py with the datastore classes, should it be in different package? Where should I put my template files and all of the py files that handle every page (should they be in the same directory as the one big common PY file)? I have tried to look for MVC and such implementations online but there are very few. Thanks, Joel

  • JSP load external php not using iFrames

    - by Rudiger
    I have a bit of an issue with a site I maintain. I have been asked to add a report to a page that sits in a jsp page. The reporting information comes from a MySQL database. The problem is to connect the jsp to the database would require added functions to code that I do not have the original source of. I thought about redoing all the db connection again but thats a lot of time for something that will probably be rewritten in 3 weeks. Then I thought of just using PHP to display the report in the jsp as I have other pages connecting to the database using php (long story as to why were are using 2 languages). But the only way I know of is by using iFrames which is a bit of a no no. Using the object tag I've seen also has errors in IE. What would be the best way to do this?

  • How to disable scrolling the document body?

    - by Manohar
    I have a HTML which has lot of content and a vertical scrollbar appears as soon as the HTML is loaded. Now from this HTML a full screen IFRAME is loaded. The problem is when the IFRAME is loaded, the parent scrollbar still persists, I want to disable the scrollbar when the Iframe is loaded. I tried: document.body.scroll = "no", it did not work with FF and chrome. document.style.overflow = "hidden"; after this I was still able to scroll, and the whole iframe would scroll up revealing the parent HTML. My requirement is, when the IFRAME is loaded, we should never be able to scroll the entire IFRAME if the parent HTML has a scrollbar. Any ideas?

  • Building an Issue Tracker Plugin for TortoiseSVN

    - by Oded
    I've read a lot about IBugTraqProvider interface and implementing an issue tracker into the commit dialog of TortoiseSVN. IBugTraqProvider is written here. Is there a more simpler way not to do it, building the plug-in and installing it on TortoiseSVN. The Document is not that clear that a developer can create its own plugin. I'm working with SalesForce as the Issue Tracker, and retrieved the WSDL file to integrate with the Working Items. Now I need to know how to connect it to TortoiseSVN. Please any suggestions?

  • Best practices for organizing .NET P/Invoke code to Win32 APIs

    - by Paul Sasik
    I am refactoring a large and complicated code base in .NET that makes heavy use of P/Invoke to Win32 APIs. The structure of the project is not the greatest and I am finding DllImport statements all over the place, very often duplicated for the same function, and also declared in a variety of ways: The import directives and methods are sometimes declared as public, sometimes private, sometimes as static and sometimes as instance methods. My worry is that refactoring may have unintended consequences but this might be unavoidable. Are there documented best practices I can follow that can help me out? My instict is to organize a static/shared Win32 P/Invoke API class that lists all of these methods and associated constants in one file... (The code base is made up of over 20 projects with a lot of windows message passing and cross-thread calls. It's also a VB.NET project upgraded from VB6 if that makes a difference.)

  • Algorithm to calculate a page importance based on its views / comments

    - by stacker
    I need an algorithm that allows me to determine an appropriate <priority> field for my website's sitemap based on the page's views and comments count. For those of you unfamiliar with sitemaps, the priority field is used to signal the importance of a page relative to the others on the same website. It must be a decimal number between 0 and 1. The algorithm will accept two parameters, viewCount and commentCount, and will return the priority value. For example: GetPriority(100000, 100000); // Damn, a lot of views/comments! The returned value will be very close to 1, for example 0.995 GetPriority(3, 2); // Ok not many users are interested in this page, so for example it will return 0.082

  • [Django] Automatically Update Field when a Different Field is Changed

    - by Gordon
    I have a model with a bunch of different fields like first_name, last_name, etc. I also have fields first_name_ud, last_name_ud, etc. that correspond to the last updated date for the related fields (i.e. when first_name is modified, then first_name_ud is set to the current date). Is there a way to make this happen automatically or do I need to check what fields have changed each time I save an object and then update the related "_ud" fields. Thanks a lot!
