• design question for transportation agency/workflow system

  - by George2

  Hello everyone, I am designing a transportation agency/workflow system, and it including 3 types of people, customer who requests to transport some stuff, drivers who deliver the stuff, and truck manager who manages transport source/destination truck coordination and communicates/organizes drivers. The system is expected to be a web site, and 3 kinds of people could use the web site to submit request, accept request, monitor status of specific stuff transportation, etc. The web site is more like an open agency or a workflow system. I am wondering whether there are any existing technologies, tools or projects (better to be open source, but not a must) which I could build my application faster based on? I prefer to use .Net technologies, but not a must. thanks in advance, George

• Why does order matter for ImageMagick's -colorspace operation?

  - by Mark Trapp

  Starting with ImageMagick 6, the command style changed to solve a bunch of problems outlined in the Basic Usage document. That document does imply that for simple operations, one should only need to move the options from before the source file to between the source and output files to convert from the "old" style to the "new" style. However, this doesn't seem to work for the -colorspace operation. When I use the following command, I get an output file with the correct colors: convert -colorspace rgb input.pdf output.png But when I try to use the new command style, the -colorspace operation is never applied: convert input.pdf -colorspace rgb output.png Samples: Why does this occur?

• Embedded Record is not getting loaded in Ember.js

  - by Venky

  Following is the JSON data I am trying to load using ember-data: { "product" : [ { "id" : 1, "name" : "product1", "master" : { "id" : 1, "name" : "product1", "images" : [ { "id" : 1, "productUrl" : "/images/product1_1.jpg" }, { "id" : 2, "productUrl" : "/images/product1_2.jpg" } ] } }, { "id" : 2, "name" : "product2", "master" : { "id" : 2, "name" : "product2", "images" : [ { "id" : 3, "productUrl" : "/images/product2_1.jpg" }, { "id" : 4, "productUrl" : "/images/product2_2.jpg" } ] } } ] } The models are as follows: App.Product = DS.Model.extend name: DS.attr('string') description: DS.attr('string') master: DS.belongsTo('master') App.Master = DS.Model.extend images: DS.hasMany('image') App.Image = DS.Model.extend productUrl: DS.attr('string') The Application Serializer code is as follows: App.ApplicationSerializer = DS.ActiveModelSerializer.extend(DS.EmbeddedRecordsMixin, attrs: { images: { embedded : 'always' } master: { embedded : 'always' } } ) The problem is that the "master" model records are being returned empty. I am not sure, where I am going wrong. I am using the following platform configuration: ember-source (1.4.0) ember-data-source (1.0.0.beta.7) ember-rails (0.15.0) Rails (4.1.0) Thanks

• Https in java ends up with strange results

  - by Senne

  I'm trying to illustrate to students how https is used in java. But i have the feeling my example is not really the best out there... The code works well on my windows 7: I start the server, go to https://localhost:8080/somefile.txt and i get asked to trust the certificate, and all goes well. When I try over http (before or after accepting the certificate) I just get a blank page, which is ok for me. BUT when I try the exact same thing on my windows XP: Same thing, all goes well. But then (after accepting the certificate first), I'm also able to get all the the files through http! (if I first try http before https followed by accepting the certificate, I get no answer..) I tried refreshing, hard refreshing a million times but this should not be working, right? Is there something wrong in my code? I'm not sure if I use the right approach to implement https here... package Security; import java.io.*; import java.net.*; import java.util.*; import java.util.concurrent.Executors; import java.security.*; import javax.net.ssl.*; import com.sun.net.httpserver.*; public class HTTPSServer { public static void main(String[] args) throws IOException { InetSocketAddress addr = new InetSocketAddress(8080); HttpsServer server = HttpsServer.create(addr, 0); try { System.out.println("\nInitializing context ...\n"); KeyStore ks = KeyStore.getInstance("JKS"); char[] password = "vwpolo".toCharArray(); ks.load(new FileInputStream("myKeys"), password); KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509"); kmf.init(ks, password); SSLContext sslContext = SSLContext.getInstance("TLS"); sslContext.init(kmf.getKeyManagers(), null, null); // a HTTPS server must have a configurator for the SSL connections. server.setHttpsConfigurator (new HttpsConfigurator(sslContext) { // override configure to change default configuration. public void configure (HttpsParameters params) { try { // get SSL context for this configurator SSLContext c = getSSLContext(); // get the default settings for this SSL context SSLParameters sslparams = c.getDefaultSSLParameters(); // set parameters for the HTTPS connection. params.setNeedClientAuth(true); params.setSSLParameters(sslparams); System.out.println("SSL context created ...\n"); } catch(Exception e2) { System.out.println("Invalid parameter ...\n"); e2.printStackTrace(); } } }); } catch(Exception e1) { e1.printStackTrace(); } server.createContext("/", new MyHandler1()); server.setExecutor(Executors.newCachedThreadPool()); server.start(); System.out.println("Server is listening on port 8080 ...\n"); } } class MyHandler implements HttpHandler { public void handle(HttpExchange exchange) throws IOException { String requestMethod = exchange.getRequestMethod(); if (requestMethod.equalsIgnoreCase("GET")) { Headers responseHeaders = exchange.getResponseHeaders(); responseHeaders.set("Content-Type", "text/plain"); exchange.sendResponseHeaders(200, 0); OutputStream responseBody = exchange.getResponseBody(); String response = "HTTP headers included in your request:\n\n"; responseBody.write(response.getBytes()); Headers requestHeaders = exchange.getRequestHeaders(); Set<String> keySet = requestHeaders.keySet(); Iterator<String> iter = keySet.iterator(); while (iter.hasNext()) { String key = iter.next(); List values = requestHeaders.get(key); response = key + " = " + values.toString() + "\n"; responseBody.write(response.getBytes()); System.out.print(response); } response = "\nHTTP request body: "; responseBody.write(response.getBytes()); InputStream requestBody = exchange.getRequestBody(); byte[] buffer = new byte[256]; if(requestBody.read(buffer) > 0) { responseBody.write(buffer); } else { responseBody.write("empty.".getBytes()); } URI requestURI = exchange.getRequestURI(); String file = requestURI.getPath().substring(1); response = "\n\nFile requested = " + file + "\n\n"; responseBody.write(response.getBytes()); responseBody.flush(); System.out.print(response); Scanner source = new Scanner(new File(file)); String text; while (source.hasNext()) { text = source.nextLine() + "\n"; responseBody.write(text.getBytes()); } source.close(); responseBody.close(); exchange.close(); } } }

• Add version control to existing SQL Server database

  - by ederbf

  I am part of a development team currently working with a database that does not have any kind of source control. We work with SQL Server 2008 R2 and have always managed the DB directly with SSMS. It now has ~340 tables and ~1600 stored procedures, plus a few triggers and views, so it is not a small DB. My goal is to have the DB under version control, so I have been reading articles, like Scott Allen's series (http://bitly.com/9cJmGR) and many old SO related questions. But I am still unable to decide on how to proceed. What I'm thinking of is to script the database schema in one file, then procedures, triggers and views in one file each. Then keep everything versioned under Mercurial. But of course, every member of the team can access SSMS and directly change the schema and procedures, with the possibility that any of us can forget to replicate those changes in the versioned files. What better options are there? And, did I forget any element worth having source control of?

• Recursive compilation using gcc

  - by curiousexplorer

  I am using the gcc compiler. My project source tree looks like somewhat like this test$~: tree . . |-- folder | |-- hello.cpp | `-- hello.h `-- main.cpp 1 directory, 3 files test$~: The file main.cpp contains the main() function and all the functions invoked by main.cpp lie in the directory named folder So far in all my little projects I never had to put some source code under a sub-directory. What I am looking for, in short, is some gcc command for recursive compilation in sub-directories and their subdirectories and so on... This command should be invoked from the home directory of the code project.

• Can I configure AutoMapper to read from custom column names when mapping from IDataReader?

  - by rohancragg

  Psuedo code for mapping configuration (as below) is not possible since the lambda only lets us access Type IDataReader, wheras when actually mapping, AutoMapper will reach into each "cell" of each IDataRecord while IDataReader.Read() == true: var mappingConfig = Mapper.CreateMap<IDataReader, IEnumerable<MyDTO>>(); mappingConfig.ForMember( destination => destination.???, options => options.MapFrom(source => source.???)); Can anyone think of a way to do this using AutoMapper configuration at runtime or just some other dynamic approach that meets the requirement below. The requirement is to support any incoming IDataReader which may have column names that don't match the property names of MyDTO and there is no naming convention I can rely on. Instead we'll ask the user at runtime to cross-reference the expected column names with the actual column names found in the IDataReader via IDataReader.GetSchemaTable().

• How to make columns as wide as the widest entry?

  - by Helper Method

  For a gcc cheatsheet I'm writing, I want to create a table which should describe how gcc interprets different file endings. The table I created so far is defined as follows: |====================================================================== |.c |C source code which must be preprocessed. |.i |C source code which should not be preprocessed. |.h |C header file to be turned into a precompiled header. |.s |Assembler code. |other | An object file to be fed straight into linking. Any file name with no recognized suffix is treated this way. |====================================================================== The problem I have is that the table spans the total page width, but what I want is that each column only is as wide as it's widest entry, and that the table will span only as much witdh as it needs.

• How can I use BeanUtils copyProperties to copy from boolean to Boolean?

  - by carrier

  BeanUtils copyProperties, out of the box, doesn't seem to handle copying from Boolean object properties to boolean primitive properties. I figured I could create and register a converter to handle this, but that just didn't seem to work. So, how can I use BeanUtils to copy the properties from class Source to class Destination where: public class Destination { private boolean property; public boolean isProperty() { return property; } public void setProperty(boolean property) { this.property = property; } } public class Source{ private Boolean property; public Boolean getProperty() { return property; } public void setProperty(Boolean property) { this.property = property; } }

• C#: My callback function gets called twice for every Sent Request

  - by Madi D.

  I've Got a program that uploads/downloads files into an online server,Has a callback to report progress and log it into a textfile, The program is built with the following structure: public void Upload(string source, string destination) { //Object containing Source and destination to pass to the threaded function KeyValuePair<string, string> file = new KeyValuePair<string, string>(source, destination); //Threading to make sure no blocking happens after calling upload Function Thread t = new Thread(new ParameterizedThreadStart(amazonHandler.TUpload)); t.Start(file); } private void TUpload(object fileInfo) { KeyValuePair<string, string> file = (KeyValuePair<string, string>)fileInfo; /* Some Magic goes here,Checking The file and Authorizing Upload */ var ftiObject = new FtiObject () { FileNameOnHDD = file.Key, DestinationPath = file.Value, //Has more data used for calculations. }; //Threading to make sure progress gets callback gets called. Thread t = new Thread(new ParameterizedThreadStart(amazonHandler.UploadOP)); t.Start(ftiObject); //Signal used to stop progress untill uploadCompleted is called. uploadChunkDoneSignal.WaitOne(); /* Some Extra Code */ } private void UploadOP(object ftiSentObject) { FtiObject ftiObject = (FtiObject)ftiSentObject; /* Some useless code to create the uri and prepare the ftiObject. */ // webClient.UploadFileAsync will open a thread that // will upload the file and report // progress/complete using registered callback functions. webClient.UploadFileAsync(uri, "PUT", ftiObject.FileNameOnHDD, ftiObject); } I got a callback that is registered to the Webclient's UploadProgressChanged event , however it is getting called twice per sent request. void UploadProgressCallback(object sender, UploadProgressChangedEventArgs e) { FtiObject ftiObject = (FtiObject )e.UserState; Logger.log(ftiObject.FileNameOnHDD, (double)e.BytesSent ,e.TotalBytesToSend); } Log Output: Filename: C:\Text1.txt Uploaded:1024 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:1024 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:2048 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:2048 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:3072 TotalFileSize: 665241 Filename: C:\Text1.txt Uploaded:3072 TotalFileSize: 665241 Etc... I am watching the Network Traffic using a watcher, and only 1 request is being sent. Some how i cant Figure out why the callback is being called twice, my doubt was that the callback is getting fired by each thread opened(the main Upload , and TUpload), however i dont know how to test if thats the cause. Note: The reason behind the many /**/ Comments is to indicate that the functions do more than just opening threads, and threading is being used to make sure no blocking occurs (there a couple of "Signal.WaitOne()" around the code for synchronization)

• Maven and db4o dependency

  - by Jens Jansson

  I'm intrigued to test new frameworks in the Java world, and decided to create a new project that takes advantage of Maven and db4o. I'm starting to get a hang of Maven, but I have a hard time adding db4o as a dependency to the project. First problem is that db4o doesn't exist in the official Maven repositories. Next up comes the problem that db4o seem to have recently restructured their whole site's URI:s, so I'm getting 'site not found' messages all the time when I try to navigate their site. I found somewhere a potential Maven repository that should be at https://source.db4o.com/maven but I get all the time "Error reading archetype catalog https://source.db4o.com/maven Unable to locate resource in repository" when I try to access it. So, any suggestions on how I'll get db4o up through Maven? I've managing Maven through Eclipse with the M2Eclipse plugin.

  I am working on an custom container and I need a border for this container. I have a 15x15 image that I am creating a 9-slice border skin with. The issue that I am having is that the border skin does not appear the way that I had hoped it would. Here is a ss of the skin in place. Ideally I should have a transparent box with a 5 pixel border around it.

• Memory issues - Living vs. overall -> app is killed

  - by D33

  I'm trying to check my applications memory issues in Instruments. When I load the application I play some sounds and show some animations in UIImageViews. To save some memory I load the sounds only when I need it and when I stop playing it I free it from the memory. problem 1: My application is using about 5.5MB of Living memory. BUT The Overall section is growing after start to 20MB and then it's slowly growing (about 100kB/sec). But responsible Library is OpenAL (OAL::Buffer), dyld (_dyld_start)-I am not sure what this really is, and some other stuff like ft_mem_qrealloc, CGFontStrikeSetValue, … problem 2: When the overall section breaks about 30MB, application crashes (is killed). According to the facts I already read about overall memory, it means then my all allocations and deallocation is about 30MB. But I don't really see the problem. When I need some sound for example I load it to the memory and when I don't need it anymore I release it. But that means when I load 1MB sound, this operation increase overall memory usage with 2MB. Am I right? And when I load 10 sounds my app crashes just because the fact my overall is too high even living is still low??? I am very confused about it. Could someone please help me clear it up? (I am on iOS 5 and using ARC) SOME CODE: creating the sound OpenAL: MYOpenALSound *sound = [[MyOpenALSound alloc] initWithSoundFile:filename willRepeat:NO]; if(!sound) return; [soundDictionary addObject:sound]; playing: [sound play]; dispatch_after(dispatch_time(DISPATCH_TIME_NOW, ((sound.duration * sound.pitch) + 0.1) * NSEC_PER_SEC), dispatch_get_current_queue(), ^{ [soundDictionary removeObjectForKey:[NSNumber numberWithInt:soundID]]; }); } creating the sound with AVAudioPlayer: [musics replaceObjectAtIndex:ID_MUSIC_MAP withObject:[[Music alloc] initWithFilename:@"mapMusic.mp3" andWillRepeat:YES]]; pom = [musics objectAtIndex:musicID]; [pom playMusic]; and stop and free it: [musics replaceObjectAtIndex:ID_MUSIC_MAP withObject:[NSNull null]]; AND IMAGE ANIMATIONS: I load images from big PNG file (this is realated also to my other topic : Memory warning - UIImageView and its animations) I have few UIImageViews and by time I'm setting animation arrays to play Animations... UIImage *source = [[UIImage alloc] initWithCGImage:[[UIImage imageNamed:@"imageSource.png"] CGImage]]; cutRect = CGRectMake(0*dimForImg.width,1*dimForImg.height,dimForImg.width,dimForImg.height); image1 = [[UIImage alloc] initWithCGImage:CGImageCreateWithImageInRect([source CGImage], cutRect)]; cutRect = CGRectMake(1*dimForImg.width,1*dimForImg.height,dimForImg.width,dimForImg.height); ... image12 = [[UIImage alloc] initWithCGImage:CGImageCreateWithImageInRect([source CGImage], cutRect)]; NSArray *images = [[NSArray alloc] initWithObjects:image1, image2, image3, image4, image5, image6, image7, image8, image9, image10, image11, image12, image12, image12, nil]; and this array I just use simply like : myUIImageView.animationImages = images, ... duration -> startAnimating

• How to get a physics engine like Nape working?

  - by Glacius

  Introduction: I think Nape is a relatively new engine so some of you may not know it. It's supposedly faster than box2d and I like that there is decent documentation. Here's the site: http://code.google.com/p/nape/ I'm relatively new to programming. I am decent at AS3's basic functionality, but every time I try to implement some kind of engine or framework I can't even seem to get it to work. With Nape I feel I got a little further than before but I still got stuck. My problem: I'm using Adobe CS5, I managed to import the SWC file like described here. Next I tried to copy the source of one of the demo's like this one and get it to work but I keep getting errors. I made a new class file, copied the demo source to it, and tried to add it to the stage. My stage code basically looks like this: import flash.Boot; // these 2 lines are as described in the tutorial new Boot(); var demo = new Main(); // these 2 are me guessing what I'm supposed to do addChild(demo); Well, it seems the source code is not even being recognized by flash as a valid class file. I tried editing it, but even if I get it recognized (give a package name and add curly brackets) but I still get a bunch of errors. Is it psuedo code or something? What is going on? My goal: I can imagine I'm going about this the wrong way. So let me explain what I'm trying to achieve. I basically want to learn how to use the engine by starting from a simple basic example that I can edit and mess around with. If I can't even get a working example then I'm unable to learn anything. Preferably I don't want to start using something like FlashDevelop (as I'd have to learn how to use the program) but if it can't be helped then I can give it a try. Thank you.

• Xcode + Perforce: it frequently shows me the spinning wheel for no reason! What can i do?

  - by GamingHorror

  While working on an Xcode project i keep getting the spinning wheel while switching files, scrolling, searching, typing, debugging, removing breakpoints, switching back from another app or saving. It also happens before compiling but usually it just happens from time to time for no apparent reason. This is the second time this started happening in a Xcode project and it's driving me nuts. It completely breaks my flow of work to have to wait for the spinning wheel to go away (2-5 seconds). What on earth could i possibly do to ... figure out what's causing the problem? resolve the problem? More details: When any project is small, everything is super-smooth with Xcode and Perforce. Two of my projects eventually had this spinning wheel problem after about 4 weeks of work. It only happened with those two projects so far. They consist of around 1000-1200 files in source control, most of them assets. The problem occurs even if i manually check out the whole project in Perforce. The problem is gone when i copy the project directory and work in the copy which is no longer under source control, or if i create a branch in Perforce and work in the branch (under source control). One of these projects i shared with a colleague, and he had exactly the same issues on his Mac. We eventually switched to Subversion and the spinning-wheel issue immediately went away. Now that i've received an updated copy of the project and simply put it under Perforce as a new project, the problem also went away (so far it did not resurface). It leads me to think that it may be caused by a larger number of file revisions. The server itself (version 2009.1) is on a different (Windows) machine on my LAN, so there's definetely no Internet lag involved. The complete repository is just 1 GB in size spread over a dozen projects or so. I'm sorry if the question seems more like a support inquiry for Perforce. However i'm using the free version of Perforce so i'm not entitled to get support from them. I hope no one minds me asking here. I'm really bummed out by this. I don't want to have to create a new branch for the project each time the spinning wheel problem surfaces.

• AutoMapper determine what to map based on generic type

  - by Daz Lewis

  Hi, Is there a way to provide AutoMapper with just a source and based on the specified mapping for the type of that source automatically determine what to map to? So for example I have a type of Foo and I always want it mapped to Bar but at runtime my code can receive any one of a number of generic types. public T Add(T entity) { //List of mappings var mapList = new Dictionary<Type, Type> { {typeof (Foo), typeof (Bar)} {typeof (Widget), typeof (Sprocket)} }; //Based on the type of T determine what we map to...somehow! var t = mapList[entity.GetType()]; //What goes in ?? to ensure var in the case of Foo will be a Bar? var destination = AutoMapper.Mapper.Map<T, ??>(entity); } Any help is much appreciated.

• Is it possible to do have Capistrano do a checkout over a reverse SSH tunnel?

  - by James A. Rosen

  I am developing an application that resides on a public host but whose source I must keep in a Git repository behind a corporate firewall. I'm getting very tired of the slowness of deploying via scp (copying the whole repository and shipping it over SSH on each deploy) and would like to have the remote host simply do a git pull to update. The problem is that the firewall prohibits incoming SSH connections. Would it be possible for me to set up an SSH tunnel from my computer to the deployment computer and use my repository as the source for the git pull? After all, git is distributed, so my copy is just as valid a repository as the central one. If this is possible, what would the tunnel command and the Capistrano configuration be? I think the tunnel will look something like ssh -R something:deployserver.com:something [email protected]
