• Umbrella websites with Microsites & Blogs - recommendations

  - by pingu

  Hi guys, I'm in the process of scoping a solution for an events organisation. Their main website features information about them and blog entries etc, but they hold major events which require microsites (domain.com/event). The microsites all have a different look-and-feel, different nav structure, and custom content-managed components. The one thing that's common across everything is the blog - it will have a category for each event under which users can post. How would you guys implement this? The solution needs to be PHP, and my initial thought was CodeIgniter but if possible I'd like to avoid building the blog functionality - so I guess I could integrate it with EE or Wordpress. If anyone has any other suggestions they would be most appreciated.

• Fully custom validation error message with Rails

  - by marcgg

  Using Rails I'm trying to get an error message like "The song field can't be empty" on save. Doing the following: validates_presence_of :song_rep_xyz, :message => "can't be empty" ... only displays "Song Rep XYW can't be empty", which is not good because the title of the field is not user friendly. How can I change the title of the field itself ? I could change the actual name of the field in the database, but I have multiple "song" fields and I do need to have specific field names. I don't want to hack around rails' validation process and I feel there should be a way of fixing that.

• Lightweight PHP server to bundle with application?

  - by munchybunch

  Does there exist some sort of PHP server that can be bundled with a locally-deployed application? It sounds wonky, but the end result is I can't use a remote web server to do anything. Clients will be downloading a package, and the plan is to use a Java backend that reads from a flat file. The flat file contains settings and is modified through a GUI written in HTML/JS, and this is where the server would come in. The forms in HTML should be able to submit to the server, which does a simple file write to the flat file. Is there any simple, lightweight server that has that simple feature? When running the executable for the application, it would start the installation process for the server before moving the web GUI files to the appropriate locations. Note that I'm doing this for a client, so I can't quite change the reqs and would rather not discuss their effectiveness. I would be ever thankful if people had suggestions for the server though!

• Is it possible to use re2 from Python?

  - by flow

  i just discovered http://code.google.com/p/re2, a promising library that uses a long-neglected way (Thompson NFA) to implement a regular expression engine that can be orders of magnitudes faster than the available engines of awk, Perl, or Python. so i downloaded the code and did the usual sudo make install thing. however, that action had seemingly done little more than adding /usr/local/include/re2/re2.h to my system. there seemed to be some `*.a file in addition, but then what is it with this *.a extension? i would like to use re2 from Python (preferrably Python 3.1) and was excited to see files like make_unicode_groups.py in the distro (maybe just used during the build process?). those however were not deployed on my machine. how can i use re2 from Python?

• How different protocols interact with eachother in Twisted

  - by stsupermouse

  The scenario I want two different protocols interact with each other is as below: A and B is two different protocols. First A will interact with the server and retrieve some values. Only after A finishes retrieving the values , B will start to interact with the server. Now my problem is that is there an elegant way to initial B when A retrieves the values. Currently I just initial B in A's data process function. But i don't think that this is an elegant way. What I mean an elegant way is that the initialization of B is done by a flow controller or something like that, but not another protocol. Is there an elegant way? such using defered or any other things. I'm just new to twisted, not knowing very much about defered.... Thank you very much!

• Programmatically Download Image to Desktop from Remote App with Ruby?

  - by viatropos

  I was thinking about making a little crop/resize batch processor online, and wanted to know if there was a way for me to do the following: upload image and specify dimensions click "process" and app resizes image image downloads automatically to wherever it was I uploaded it (say from my desktop), but with a new name (based on the time for example). This would make it so I could host a free image processor that never stored any data other than tempfiles. Is that possible? Something like Rails' send_file method, but I'm using Sinatra and am looking for something in pure ruby.

• Beginner's resources/introductions to classification algorithms.

  - by Dirk

  Hi, everybody. I am entirely new to the topic of classification algorithms, and need a few good pointers about where to start some "serious reading". I am right now in the process of finding out, whether machine learning and automated classification algorithms could be a worthwhile thing to add to some application of mine. I already scanned through "How to Solve It: Modern heuristics" by Z. Michalewicz and D. Fogel (in particular, the chapters about linear classifiers using neuronal networks), and on the practical side, I am currently looking through the WEKA toolkit source code. My next (planned) step would be to dive into the realm of Bayesian classification algorithms. Unfortunately, I am lacking a serious theoretical foundation in this area (let alone, having used it in any way as of yet), so any hints at where to look next would be appreciated; in particular, a good introduction of available classification algorithms would be helpful. Being more a craftsman and less a theoretician, the more practical, the better... Hints, anyone?

  - by AndroidUser99

  i want to show a PD when my activity A starts another activity B. But in that onclick method, my A activity haves to do some work before start B, and B also haves to do some work because it haves to load a lot of data for the UI. I need a PD that is viewed by the user in all the process of the loading data of changin from activity A to B. ¿how can do it? i tryed storing a static ProgressDialog on MyApplication.java, and with these methods: public static void showProgressDialog(Context c) { pd = ProgressDialog.show(c, c.getResources().getString(R.string.app_name), c.getResources().getString(R.string.loading), true, false); } public static void dismissProgressDialog(){ pd.dismiss(); } but it doesn't works, it doesn't shows nothing, i dont know why how to achieve this by a easy way? i know that i can do it with async task, but that is too hard for me, i can't understand the code examples i am finding on this web and google code examples are welcome thanks

• Possible to map a new file extension to an existing handler in ASP.NET?

  - by Dave

  I have a scenario where my application is going to be publishing services that are consumed by both PC's and mobile devices, and I have a HTTPModule that I want to only perform work on only the mobile requests. So I thought the best way of doing this was to point the mobile requests to a different file extension and have the HTTPModule decide to process only if the request targets this new extension. I don't need a custom HTTPHandler for the new extension; I want to program the services like a normal .ASMX service, just with a different extension. First, can I do this? If so, how do I do it so that requests to my new extension are handled just like .ASMX requests? Second, is this the right approach? Am I going about separating and managing the mobile vs. PC requests the wrong way? Thanks, Dave

• How to get application to use specific version of .NET?

  - by HN

  Hi, I am using pnunit to run nunit tests on remote machines, the pnunit agent loads the test and runs it in Windows 2008 but the test fails to load in Windows 2003, the agent error is INFO PNUnit.Agent.PNUnitAgent - Registering channel on port 9080 INFO PNUnit.Agent.PNUnitAgent - RunTest called for Test MyTest, AssemblyName test.dll, TestToRun test.Program.myDeployTest INFO PNUnit.Agent.PNUnitTestRunner - Spawning a new thread INFO PNUnit.Agent.PNUnitTestRunner - Thread entered for Test MyTest:test.Program.myDeployTest Assembly test.dll Unhandled Exception: System.BadImageFormatException: The format of the file 'test ' is invalid.

• JPA DAO integration test not throwing exception when duplicate object saved?

  - by HDave

  I am in the process of unit testing a DAO built with Spring/JPA and Hibernate as the provider. Prior to running the test, DBUnit inserted a User record with username "poweruser" -- username is the primary key in the users table. Here is the integration test method: @Test @ExpectedException(EntityExistsException.class) public void save_UserTestDataSaveUserWithPreExistingId_EntityExistsException() { User newUser = new UserImpl("poweruser"); newUser.setEmail("[email protected]"); newUser.setFirstName("New"); newUser.setLastName("User"); newUser.setPassword("secret"); dao.persist(newUser); } I have verified that the record is in the database at the start of this method. Not sure if this is relevant, but if I do a dao.flush() at the end of this method I get the following exception: javax.persistence.PersistenceException: org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update

• Preallocate memory for a program in Linux before it gets started

  - by Fyg

  Hi, folks, I have a program that repeatedly solves large systems of linear equations using cholesky decomposition. Characterising is that I sometimes need to store the complete factorisation which can exceed about 20 GB of memory. The factorisation happens inside a library that I call. Furthermore, this matrix and the resulting factorisation changes quite frequently and as such the memory requirements as well. I am not the only person to use this compute-node. Therefore, is there a way to start the program under Linux and preallocate free memory for the process? Something like: $: prealloc -m 25G ./program

• Best way to store data for Greasemonkey based crawler?

  - by Björn

  I want to crawl a site with Greasemonkey and wonder if there is a better way to temporarily store values than with GM_setValue. What I want to do is crawl my contacts in a social network and extract the Twitter URLs from their profile pages. My current plan is to open each profile in it's own tab, so that it looks more like a normal browsing person (ie css, scrits and images will be loaded by the browser). Then store the Twitter URL with GM_setValue. Once all profile pages have been crawled, create a page using the stored values. I am not so happy with the storage option, though. Maybe there is a better way? I have considered inserting the user profiles into the current page so that I could all process them with the same script instance, but I am not sure if XMLHttpRequest looks indistignuishable from normal user initiated requests.

• Dang Error #1009 !

  - by boz

  I'm building a simple flash site for a friend who has a spa. I keep getting this error: Error #1009: Cannot access a property or method of a null object reference. at spa7_fla::MainTimeline/frame1() through the process of commenting out code, i've narrowed down to my link section: vox_link.addEventListener(MouseEvent.CLICK,gotoVox); function gotoVox(evtObj:Event):void { var voxSite:URLRequest=new URLRequest("http://www.voxmundiproject.com"); navigateToURL(voxSite, "_blank"); } With this section commented out, i don't get the 1009 error. When the code is active, I get the error. My code syntax is correct so I'm stumped. Does someone have an idea what my be wrong? Thanks!

• $(MSBuildStartupDirectory) in Visual Studio points to different places on different machines

  - by skolima

  In a large solution, I'm integrating Gendarme into Visual Studio 2008 compilation process. I am using GendarmeMsBuild task along with a .targets file to add a AfterBuild target to every project in the solution. I am looking for a way to import this file into .csproj files in a way that wouldn't require me to change the include path (the projects have different nesting levels). Apart from using NuGet SolutionDir variable, best way to solve this seemed to be to use $(MSBuildStartupDirectory). However, as it turns out, on some machines, using the same version of VS 2008 (as same updates installed, as far as I was able to check) this resolves to the solution directory, and on others to c:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE. How can I either get this to always resolve to the solution folder or obtain the base folder in another consistent way?

• How to stop the execution of Java program from Command line?

  - by Aakash

  My main field is .Net but recently I have got something to do with Java. I have to create a shell utility in Java that could run in background reading few database records after specified duration and do further processing. It's a kind of scheduler. Now I have few concerns: How to make this work as a service. I want to execute it through a shell script and the utility should start running. Off course the control should get back to the calling script. Secondly, eventually i may want to stop this process from running. How to achieve this? I understand these are basic question but I really have no idea where to begin and what options are best for me. Any help / advise please?

• Git to SVN trouble

  - by Kevin

  My boss has a Perforce repository for which he wants to make a read-only copy available on Sourceforge via subversion. He had a perl script which would do this but it's no longer functioning (we don't want to try debugging it yet) and it's really not that great anyway. So an alternate solution is to pull the perforce repo into git as a remote ref, which I have already done successfully (including all the proper commit details and authors), now the trouble I'm having is pushing it out to a separate SVN repository. I can make it start the commit process with "git svn dcommit --add-author-from", but the problem is even though the correct author appears at the end of the commit message the "real" author committing is my machine's user. I want to preserve the real author with the commit, and I'd also like to preserve the original timestamps as well. Is anyone familiar with how I could accomplish this?

• Ant database rebuild script, avoiding interactive prompting

  - by fras85

  Hi Guys. I'm writing an ant script to rebuild our database i.e. dropping everything and rebuilding from scratch. The problem our DBA adds a Y/N prompt before executing the rest of the script, and therefore we can't call this from an automated build process. Does anyone have any suggestions to circumvent the Y/N prompt? Obviously we could create seperate scripts, one for the DBA's and one for the automated build - but this requires maintaning both. We're running on Windows so it's not as easy as using sed to strip out the prompt...but i'm thinking something along those lines. Not sure if that's clear enough but hope you can help. Cheers.

• Is File good for Interprocess communication

  - by Karthik

  Hi, I have an EXE and DLL running in different process. From DLL I have to send large of amount of data to EXE, which would vary from 50 chars to 2000 chars and more(The data is recordid of records saved in DB). I thought about two options to do that: 1. Using SendMessage- In which data's will be sent in batch. 2. Use an Intermediate file to transfer data. Can anyone list out the pros and cons of methods. I have developed my components using C#.NET Thanks you folks.

• Why is EventListenerList traversed backwards in fireFooXXX()?

  - by Joonas Pulakka

  I don't understand the rationale of this code, taken from javax.swing.event.EventListenerList docs: protected void fireFooXXX() { // Guaranteed to return a non-null array Object[] listeners = listenerList.getListenerList(); // Process the listeners last to first, notifying // those that are interested in this event for (int i = listeners.length-2; i>=0; i-=2) { if (listeners[i]==FooListener.class) { // Lazily create the event: if (fooEvent == null) fooEvent = new FooEvent(this); ((FooListener)listeners[i+1]).fooXXX(fooEvent); } } } Why is the list traversed backwards? Why is only every second listener called? The event firing is implemented exactly this way in javax.swing.tree.DefaultTreeModel among others, so it's obviously me who's just not getting something.

• JQuery - is at least one checkbox checked

  - by Laramie

  I am in the process of learning JQuery thanks mostly to the positive reference here on Stack Overflow. I need a function that checks all the checkboxes in an element which have the same CSS class. It should returns true if at least one of them is checked. There are also other boxes in the element that are irrelevant to the check. The CSS class is unnecessary and only in place to create a way to identify the checkboxes in the group. It feels like bad practice, so any recommendations about other ways to identify them are welcome.

• Xcode 3.2 says the version of iPhone OS isn't supported when my iPhone OS is version 3.1.3

  - by fr0man

  I just went through the whole certificate/keychain/provisioning/appID/profile/DNA test process to get my app running on my iPhone. Turns out my iPhone OS was out of date (3.0.1 I think), so I updated it. Now it says The version of iPhone OS on “Stefanie's phone” does not match any of the versions of iPhone OS supported for development with this copy of Xcode. Please restore the device to a version of the OS listed below. If necessary, the latest version of Xcode is available here. OS Installed on Stefanie's phone 3.1.3 (7E18) Xcode Supported iPhone OS Versions 3.1.2 (7D11) 3.1.1 (7C146) 3.1.1 (7C145) 3.1 (7C144) 3.0.1 (7A400) 3.0 2.2.1 2.2 2.1.1 2.1 2.0.2 (5C1) 2.0.1 (5B108) 2.0 (5A347) But I have Xcode 3.2.1, which is supposed to support iPhone OS 3.1.3. What am I doing wrong? I have a cruddy internet connection (HughesNet), so I can't upgrade the Xcode SDK without it taking literally days.
