  • Is there any Java Decompiler that can correctly decompile calls to overloaded methods?

    - by mihi
    Consider this (IMHO simple) example: public class DecompilerTest { public static void main(String[] args) { Object s1 = "The", s2 = "answer"; doPrint((Object) "You should know:"); for (int i = 0; i < 2; i++) { doPrint(s1); doPrint(s2); s1 = "is"; s2 = new Integer(42); } System.out.println(); } private static void doPrint(String s1) { System.out.print("Wrong!"); } private static void doPrint(Object s1) { System.out.print(s1 + " "); } } Compile it with source/target level 1.1 without debug information (i.e. no local variable information should be present) and try to decompile it. I tried Jad, JD-GUI and Fernflower, and all of them got at least one of the call wrong (i. e. the program printed "Wrong!" at least once) Is there really no java decompiler that can infer the right casts so that it will not call the wrong overload?

  • Trouble extending event log messages

    - by Matt H
    Hi. I'm trying to add some extended error codes to the event log but I get the following error. The description for Event ID ( 109 ) in Source ( PumpServer ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: The event log file is corrupt.. The message file looks like this and I added the one on the end:- <---snip---> MessageId= SymbolicName=EVMSG_BADREQUEST Language=English The service received an unsupported request. . MessageId= SymbolicName=EVMSG_DEBUG Language=English %1 . MessageId= SymbolicName=EVMSG_STOPPED Language=English The service was stopped. . MessageId= SymbolicName=EVMSG_INVALIDLICENCE Language=English The service does not have a valid licence. Initialization failed. . It compiles fine. The mc program is running over this file and producing a header file of the same name with my new message id showing. // // MessageId: EVMSG_INVALIDLICENCE // // MessageText: // // The service does not have a valid licence. Initialization failed. // #define EVMSG_INVALIDLICENCE 0x0000006DL Any ideas why it's not finding my message? All the others work.

  • How to get the equivalent of the accuracy in Google Map Geocoder V3

    - by Scorpi0
    Hi, I want to get geocode from google, and I used to do it with the V2 of the API. Google send in the json a pretty good information, the accuracy, reference here : http://code.google.com/intl/fr-FR/apis/maps/documentation/javascript/v2/reference.html#GGeoAddressAccuracy In V3, Google doesn't seem to send me exactly the same information. There is the array "adresse_component", which seem bigger if the accuracy is better, but not exactly. For example, I have a request accuracy to the street number, the array is of size 8. Another query is accuracy to the route, so less accuracy, but the array is style of size 8, as there is a row 'sublocality', which not appear in the first case. Ok, for a result, Google send a data 'types', which have the 'best' accuracy. This types are here : http://code.google.com/intl/fr-FR/apis/maps/documentation/geocoding/#Types But, there is no real order, and if I wan't the result better than postal_code, I have no clue to how to do that. So, how can I get this equivalent of the V2 accuracy, whithout some dumb and horrible code ?

  • What is the best URL strategy to handle multiple search parameters and operators?

    - by Jon Winstanley
    Searching with mutltiple Parameters In my app I would like to allow the user to do complex searches based on several parameters, using a simple syntax similar to the GMail functionality when a user can search for "in:inbox is:unread" etc. However, GMail does a POST with this information and I would like the form to be a GET so that the information is in the URL of the search results page. Therefore I need the parameters to be formatted in the URL. Requirements: Keep the URL as clean as possible Avoid the use of invalid URL chars such as square brackets Allow lots of search functionality Have the ability to add more functions later. I know StackOverflow allows the user to search by multiple tags in this way: http://stackoverflow.com/questions/tagged/c+sql However, I'd like to also allow users to search with multiple additional parameters. Initial Design My design is currently to do use URLs such as these: http://example.com/search/tagged/c+sql/searchterm/transactions http://example.com/search/searchterm/transactions http://example.com/search/tagged/c+sql http://example.com/search/tagged/c+sql/not-tagged/java http://example.com/search/tagged/c+sql/created/yesterday http://example.com/search/created_by/user1234 I intend to parse the URL after the search parameter, then decide how to construct my search query. Has anyone seen URL parameters like this implemented well on a website? If so, which do it best?

  • Save PyML.classifiers.multi.OneAgainstRest(SVM()) object?

    - by Michael Aaron Safyan
    I'm using PYML to construct a multiclass linear support vector machine (SVM). After training the SVM, I would like to be able to save the classifier, so that on subsequent runs I can use the classifier right away without retraining. Unfortunately, the .save() function is not implemented for that classifier, and attempting to pickle it (both with standard pickle and cPickle) yield the following error message: pickle.PicklingError: Can't pickle : it's not found as __builtin__.PySwigObject Does anyone know of a way around this or of an alternative library without this problem? Thanks. Edit/Update I am now training and attempting to save the classifier with the following code: mc = multi.OneAgainstRest(SVM()); mc.train(dataset_pyml,saveSpace=False); for i, classifier in enumerate(mc.classifiers): filename=os.path.join(prefix,labels[i]+".svm"); classifier.save(filename); Notice that I am now saving with the PyML save mechanism rather than with pickling, and that I have passed "saveSpace=False" to the training function. However, I am still gettting an error: ValueError: in order to save a dataset you need to train as: s.train(data, saveSpace = False) However, I am passing saveSpace=False... so, how do I save the classifier(s)? P.S. The project I am using this in is pyimgattr, in case you would like a complete testable example... the program is run with "./pyimgattr.py train"... that will get you this error. Also, a note on version information: [michaelsafyan@codemage /Volumes/Storage/classes/cse559/pyimgattr]$ python Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information. import PyML print PyML.__version__ 0.7.0

  • Tag/Keyword based recommendation

    - by Hellnar
    Hello I am wondering what algorithm would be clever to use for a tag driven e-commerce enviroment: Each item has several tags. IE: Item name: "Metallica - Black Album CD", Tags: "metallica", "black-album", "rock", "music" Each user has several tags and friends(other users) bound to them. IE: Username: "testguy", Interests: "python", "rock", "metal", "computer-science" Friends: "testguy2", "testguy3" I need to generate recommendations to such users by checking their interest tags and generating recommendations in a sophisticated way. Ideas: A Hybrid recommendation algorithm can be used as each user has friends.(mixture of collaborative + context based recommendations). Maybe using user tags, similar users (peers) can be found to generate recommendations. Maybe directly matching tags between users and items via tags. Any suggestion is welcome. Any python based library is also welcome as I will be doing this experimental engine on python language.

  • Codeigniter: db data in controller

    - by Kevin Brown
    I'm confused about what to do... I'm working on a user's page where they can view certain things only if their supervisor has given them "money" or "credits". I need a simple way to get the person that is their supervisor by doing something like: $data['employer'] = $this->home_model->getEmployees(array('user_id'=>$manager_id)); Basically, get the user information about a person who's user_id matches the manager_id of the currently logged in member. I don't know how to set the variable $manager_id. Additional Information: The current user has an id, and a manager_id. I need the id of the manager. So, I need to grab the manager_id of the logged-in user and find the manager who's user_id is that of the manager_id. What's the process to do this? I can get each individually, but I don't know how to use one to get the other... I know it is confusing, but I'm confused! Thanks for the help!

  • Is it safe to use random Unicode for complex delimiter sequences in strings?

    - by ccomet
    Question: In terms of program stability and ensuring that the system will actually operate, how safe is it to use chars like ¦, § or ‡ for complex delimiter sequences in strings? Can I reliable believe that I won't run into any issues in a program reading these incorrectly? I am working in a system, using C# code, in which I have to store a fairly complex set of information within a single string. The readability of this string is only necessary on the computer side, end-users should only ever see the information after it has been parsed by the appropriate methods. Because some of the data in these strings will be collections of variable size, I use different delimiters to identify what parts of the string correspond to a certain tier of organization. There are enough cases that the standard sets of ;, |, and similar ilk have been exhausted. I considered two-char delimiters, like ;# or ;|, but I felt that it would be very inefficient. There probably isn't that large of a performance difference in storing with one char versus two chars, but when I have the option of picking the smaller option, it just feels wrong to pick the larger one. So finally, I considered using the set of characters like the double dagger and section. They only take up one char, and they are definitely not going to show up in the actual text that I'll be storing, so they won't be confused for anything. But character encoding is finicky. While the visibility to the end user is meaningless (since they, in fact, won't see it), I became recently concerned about how the programs in the system will read it. The string is stored in one database, while a separate program is responsible for both encoding and decoding the string into different object types for the rest of the application to work with. And if something is expected to be written one way, is possibly written another, then maybe the whole system will fail and I can't really let that happen. So is it safe to use these kind of chars for background delimiters?

  • Associate new Authlogic Model to existing Models

    - by BriteLite
    Hello, While playing around with Rails (since I am a newbie) while reading Agile Rails book I came across an issue using the Gem Authlogic that I don't know how to address. I have a simple business Model. The tables store the following information: Name, Address, Latitude, and Longitude. The above approach has been working fine, because using the console I can enter the information and it shows up, where I need it to. My issue now is that I want to add authentication to it. As in assign those records in the table, to individual accounts. Since Authlogic is an authentication gem, can this be done? What I am trying to get to here is that, I enter a few records and leave it at that. Few days later, I want to assign those individual rows in the table to an authlogic model so the person to whom the record should belong can authenticate to it and make changes. Any code samples, blog posts to better help me understand would be great! Thank You.

  • User Management: Managing users in user-defined "groups", database schema and logistics

    - by Kevin Brown
    I'm a noob, development wise and logistically-wise. I'm developing a site that lets people take a test... My client wants the ability for a user with the roll/privledge "admin" (a step below a super-admin) to be allowed to create users and only see/edit the users that they create... The users created in that "category" or group need some information that their superior provides. For example, I log in as a "manager", I have the ability to invite people to take the test, and manage those people. Before adding those people, I will have filled out a short survey about myself... Right now, the users that are invited will be asked some of the same questions as the manager. I'd like to cut down the redundancy by using the information put into the database by the manager and apply it to the invited users. How do I set up my database to work with this criterion? I'm a little confused about how to do this! Let me know if I can add more details... (This is a mysql and php app)

  • How can I get a static URL to a map image using the Google Static Maps API?

    - by Argote
    === BACKGROUND === Hello, so I've published a Web-App (still in "Beta") which uses the Flickr API to get information for the photos of a particular Flickr user and generates IPB code to post any of his/her images. While Flickr now gives you the IPB code to show the image and link back to the photo site directly on its site, my App also has the option of embeding the title, description, select EXIF data, location information, etc. into the post for the IPB forum. === PROBLEM === I've most recently added the option to integrate a Google Maps image of the photo's geolocation data into the post by using the Google Static Maps API. The problem is that the image URL I have is in the following form (including IPB [IMG] tags): [IMG]http://maps.google.com/maps/api/staticmap?zoom=16&size=600x600&maptype=hybrid&markers=19.387687,-99.251732&sensor=false[/IMG] Which shows this example image (In practice the image size is user selectable): However, some IPB forums seem to not support dyamic image URLs which gives me a broken image, I'd like to replace the [IMG]http://maps.google.com/maps/api/staticmap?zoom=16&size=600x600&maptype=hybrid&markers=19.387687,-99.251732&sensor=false[/IMG] with something like [IMG]http://maps.google.com/maps/api/staticmap/map0000001.png[/IMG] which should be supported by all IPB forums. Thanks in advance for your help. In case you're interested, the most recent "released" version of my Web-App can be found here: http://flickr.argote.mx/ (The changes I mention here are still on local development server).

  • How to setup Continuous Integration and Continuous Deployment for Django projects?

    - by ycseattle
    Hello, I am researching about how to set up CI and continuous deployment for a small team project for a Django based web application. Here are needs: Developer check in the code into a hosted SVN server (unfuddle.com) A CI server detects new checkin, check out the source, build, run functional tests. If tests all passed, deploy the code to the webserver on Amazon EC2. For now, the CI server is also responsible to run the functional tests. I figured out that I can use Husdon as the CI server, use Selenium to run functional tests, and use Fabric to deploy the build to remote web server in Amazon cloud. I am new to Django development and not very familiar with opensource tools. My questions are: I can find some information to integrate hudson with selenium, but I couldn't find much information on how to integrate Fabric to Hudson as well. Is this setup viable? Do you see problems? How do I integrate and deploy database changes? Most likely in the early stage we will change database schema very often with code changes. I used to use Visual Studio and the database project made it very simple to deploy. I wonder if there is "established, well-supported" way to do that. Thanks!!

  • Will being self-taught limit me?

    - by Isaiah
    I'm 21 and am pretty efficient in html/css, python, and javascript. I also know my way around lisp languages and enjoy programing in them. My problem is that I'm extremely self-taught and not quite confident that I could land a job programing, but I really need a job soon as I've just become a father. I haven't even created a resume yet because I'm not really sure what to put on it except my lone experience. So I wanted to ask, will being primarily self-taught with some experience on small projects I've done for a few clients limit me too much? I mean I know I need some kind of education so I've enrolled part time in a community college to work on a degree in computer science, but it's years till then. And if it will limit me a lot, what kind of skills would be good to work on to make my chances any better? Thank You

  • ASP.NET web setup class is not defined

    - by Wayne Werner
    Hi, I've got an ASP.NET application that I installed by creating a web setup. I ran into a problem where ASP.NET wasn't registered with IIS so it gave me a "installation was interrupted" message that told me exactly nothing. Anyhow, I finally got it installed, and I can access the main page, but it's telling me that my class isn't defined. The dll is in the same directory as the Default.aspx page Here's the main error information Compiler Error Message: BC30002: Type 'SIValidator.SIValidator' is not defined. Source Error: Line 4: Line 5: <script runat="server"> Line 6: Dim validator As New SIValidator.SIValidator() Line 7: Protected table As New arrayList() Line 8: Protected countyByDistrict As New Hashtable() Version Information: Microsoft .NET Framework Version:2.0.50727.1873; ASP.NET Version:2.0.50727.1433 Am I doing it wrong? Is there some obscure setting that may not be set? I'm completely new to this VS deployment deal, so I'm trying to learn the right terms to ask the right questions... Thanks for any help edit: As an aside, when I searched google 5 minutes later, this entry came up as the first result. Would have been awesome if there was an answer for me then :P

  • Dataflow Pipeline holding on to memory

    - by Jesse Carter
    I've created a Dataflow pipeline consisting of 4 blocks (which includes one optional block) which is responsible for receiving a query object from my application across HTTP and retrieving information from a database, doing an optional transform on that data, and then writing the information back in the HTTP response. In some testing I've done I've been pulling down a significant amount of data from the database (570 thousand rows) which are stored in a List object and passed between the different blocks and it seems like even after the final block has been completed the memory isn't being released. Ram usage in Task Manager will spike up to over 2 GB and I can observe several large spikes as the List hits each block. The signatures for my blocks look like this: private TransformBlock<HttpListenerContext, Tuple<HttpListenerContext, QueryObject>> m_ParseHttpRequest; private TransformBlock<Tuple<HttpListenerContext, QueryObject>, Tuple<HttpListenerContext, QueryObject, List<string>>> m_RetrieveDatabaseResults; private TransformBlock<Tuple<HttpListenerContext, QueryObject, List<string>>, Tuple<HttpListenerContext, QueryObject, List<string>>> m_ConvertResults; private ActionBlock<Tuple<HttpListenerContext, QueryObject, List<string>>> m_ReturnHttpResponse; They are linked as follows: m_ParseHttpRequest.LinkTo(m_RetrieveDatabaseResults); m_RetrieveDatabaseResults.LinkTo(m_ConvertResults, tuple => tuple.Item2 is QueryObjectA); m_RetrieveDatabaseResults.LinkTo(m_ReturnHttpResponse, tuple => tuple.Item2 is QueryObjectB); m_ConvertResults.LinkTo(m_ReturnHttpResponse); Is it possible that I can set up the pipeline such that once each block is done with the list they no longer need to hold on to it as well as once the entire pipeline is completed that the memory is released?

  • AJAX Partial Rendering issues for the default page in IIS 7 when using custom http module

    - by WiseGuyEh
    The problem When I try to make a AJAX partial update request (using the UpdatePanel control) from the default page of an IIS7 web site, it fails- instead of returning the html to be updated, it returns the entire page, which then causes the MS AJAX Javascript to throw a parsing shit-fit. The suspected cause I have narrowed the cause down to two issues- making an AJAX request to the default page when I have a certain custom http module registered. A partial rendering request to http://localhost will fail, but a partial rendering request to http://localhost/default.aspx will work fine. Also, If i remove the following line in my custom HttpModule: _application.PreRequestHandlerExecute += OnPreRequestHandlerExecute; The AJAX partial render will work correctly. Wierd huh? Another wierd thing... If I look at trace.axd, I can see that when a partial rendering request fails, two POST requests are logged for the one partial rendering request- one where the default.aspx page executes successfully (trace information such as page_load is logged) but no content is produced and a second that doesn't seem to actually execute (no trace information is logged) but produces content (HTTP_CONTENT_LENGTH is greater than 0). Please help! If anyone with a good knowledge of HTTP modules or the MS AJAX Http module could explain why this is occuring I would be very grateful. As it is, the obvious work arround is to just redirect to default.aspx if the request url is "/" but I would really like to understand why this is occurring.

  • Comprehending the Semantic web and it's methods, syntax, vocabularies and languages

    - by DreamCodeR
    Hi. I have just been introduced to the semantic web and it's family of functions but I have a hard time understanding some of it, which I was hoping someone could explain to me. As far as I've understood, RDF can be written in several syntaxes. RDF/XML, Turtle, etc. Now, I understand XML. How it is presented and how it can be parsed. However, some people write in the turtle syntax, but how do they parse that information? I can't seem to find a single library for any language to "extract" the information written in a turtle syntax into another form. The same goes for N3. How can it be used? Executed or else? I seem to be able to understand RDFa. That it is a way to implement RDF into XHTML. For me that is a way to implement RDF into "something". But how can I compare that to turtle, N3, or the like? Thanks in advance.

  • Accessing functions in a parent controller

    I have made a ViewController in XCode for an iPhone project I'm working on, but I have a question about nested ViewControllers and what the best way to access a parents ViewController functions? Essentially, at the moment I have a SwitchViewController with MenuViewController (nested) and GameViewController (nested, which renders OpenGL ES). At the moment, I have animated view switching controlled in the SwitchViewController which works. But I want to call it after a player has selected the level from the MenuViewController and run the appropriate level in GameViewController. Not rocket science, I know. What's the best way to call parent functions?

  • iOS MapKit: Selected MKAnnotation coordinates.

    - by Oh Danny Boy
    Using the code at the following tutorial, http://www.zenbrains.com/blog/en/2010/05/detectar-cuando-se-selecciona-una-anotacion-mkannotation-en-mapa-mkmapview/, I was able to add an observer to each MKAnnotation and receive a notification of selected/deselected states. I am attempting to add a UIView on top of the selection annotation to display relevant information about the location. This information cannot be conveyed in the 2 lines allowed (Title/Subtitle) for the pin's callout. - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { Annotation *a = (Annotation *)object; // Alternatively attempted using: //Annotation *a = (Annotation *)[mapView.selectedAnnotations objectAtIndex:0]; NSString *action = (NSString *)context; if ([action isEqualToString:ANNOTATION_SELECTED_DESELECTED]) { BOOL annotationSelected = [[change valueForKey:@"new"] boolValue]; if (annotationSelected) { // Actions when annotation selected CGPoint origin = a.frame.origin; NSLog(@"origin (%f, %f) ", origin.x, origin.y); // Test UIView *v = [[UIView alloc] init]; [v setBackgroundColor:[UIColor orangeColor]]; [v setFrame:CGRectMake(origin.x, origin.y , 300, 300)]; [self.view addSubview:v]; [v release]; }else { // Accions when annotation deselected } } } Results using Annotation *a = (Annotation *)object origin (154373.000000, 197135.000000) origin (154394.000000, 197152.000000) origin (154445.000000, 197011.000000) Results using Annotation *a = (Annotation *)[mapView.selectedAnnotations objectAtIndex:0]; origin (0.000000, 0.000000) origin (0.000000, 0.000000) origin (0.000000, 0.000000) The numbers are large. They are not relative to the view (1024 x 768). I believe they are relative to the entire map. How would I be able to detect the exact coordinates relative to the entire view so that I can appropriately position my view?

  • rest and client rights integration, and backbone.js

    - by Francois
    I started to be more and more interested in the REST architecture style and client side development and I was thinking of using backbone.js on the client and a REST API (using ASP.NET Web API) for a little meeting management application. One of my requirements is that users with admin rights can edit meetings and other user can only see them. I was then wondering how to integrate the current user rights in the response for a given resource? My problem is beyond knowing if a user is authenticated or not, I want to know if I need to render the little 'edit' button next to the meeting (let's say I'm listing the current meetings in a grid) or not. Let's say I'm GETing /api/meetings and this is returning a list of meetings with their respective individual URI. How can I add if the user is able to edit this resource or not? This is an interesting passage from one of Roy's blog posts: A REST API should be entered with no prior knowledge beyond the initial URI (bookmark) and set of standardized media types that are appropriate for the intended audience (i.e., expected to be understood by any client that might use the API). From that point on, all application state transitions must be driven by client selection of server-provided choices that are present in the received representations or implied by the user’s manipulation of those representations It states that all transitions must be driven by the choices that are present in the representation. Does that mean that I can add an 'editURI' and a 'deleteURI' to each of the meeting i'm returning? if this information is there I can render the 'edit' button and if it's not there I just don't? What's the best practices on how to integrate the user's rights in the entity's representation? Or is this a super bad idea and another round trip is needed to fetch that information?

    I am looking for an Open Source alternative to SAAS provided by lablife.org website. Main purpose of the service is to automate daily tasks for life science laboratory. This service was free and nice to use, but when the original company developing this service was bought by BioData they kind of decided to kill and replace it with a new service called labguru. Apparently, a new service has a lot of functionality missing or just bad. That's why I am on a search for an alternative solution. So if you are familiar with what this software does - and if there are any known alternatives, I would be very grateful for any of your tips.

  • Internet explorer 8 opens file in browser instead of the client

    - by Rogier
    Our company is working with a great Business Intelligence tool CorVu 4.2 to analyse the operational and strategic data. Since several years we are successfully working with Sharepoint 2007 to collaborate and share information with colleagues. Most of my colleagues are working with Internet Explorer 7, but step by step Internet Explorer 8 is implemented in the company. We share a lot of CorVu files thought Sharepoint, but since we are using Internet Explorer 8, we have a problem that is new for us. If we click on a CorVu file in Internet Explorer 8 (not necessarily in Sharepoint) a pop-up shows how to open the file, if we save the file, there is no problem. But if we open the file, the file is shown in the browser and not in the CorVu client! See the screenshot below: link (I removed some unnecessary information) So far my colleagues accept this 'feature' in Internet Explorer 8. But I we open and closes more CorVu files, multiple errors (more than 10) show up starting with: (unable to place more hyperlinks) By pressing Enter the errors disappear, but it's not professional! I contacted the creators of CorVu, but they don't have a solution for in their client. There may be a solution in Internet Explorer 8? The extensions of a CorVu file can be a .sqy, .tab or .qrp. But is it possible to force the files to open in the standard client instead of the browser?

  • Web application architecture, and application servers?

    - by seanieb
    Hi, I'm building a web application, and I need to use an architecture that allows me to run it on two servers. The application scrapes information from other sites periodically, and on input from the end user. To do this I'm using Php+curl to scrape the information, Php or python to parse it and store the results in a MySQLDB. Then I will use Python to run some algorithms on the data, this will happen both periodically and on input from the end user. I'm going to cache some of the results in the MySQL DB and sometimes if it is specific to the user, skip storing the data and serve it to the user. I'm think of using Php for the website front end on a separate web server, running the Php spider, MySQL DB and python on another server. As you can see I'm fairly clueless. I'm familiar with using Php, MySQL and the basics of Python, but bringing this all together using something more complex than a cron job is new to me. How do go about implementing this? What frame work(s) should I use? Is MVC a good architecture for this? (I'm new to MVC, architectures etc.) Is Cakephp a good solution? If so will I be able to control and monitor the Python code using it?
