  • Premium Services - Ad blocker legal or illegal?

    - by René
    Ok, maybe thats kind of a stupid question. But let's try to get an answer. I'm building a Desktop Solution for an existing web service. That web service is only available without ads when you pay for a premium account. Would it be illegal when I block this ads in my Desktop Application? When you use this web service over the browser, every user has the chance to block ads with adblocker addons. So why not block this stuff in my Desktop Application?

  • Real life Java Swing Project

    - by santiagobasulto
    Hi everybody! I've been working with swing for the last 2 years, but i'm still not satisfy with my own work. The apps are "fast" enough, but the development isn't enough "clean". Can you recommend me any real world project, book, or something similar that shows me how a real world swing app work. May be a framework, something structured, etc. For example, i'm thinking i may code a "window manager" that has all the window of the app in an unified resource, may be cached, etc. I think all those good ideas must be implemented already. Thanks!

  • Stored Procedure or calculations via IQueryable?

    - by Shawn Mclean
    This is a question that is based on choosing performance over design practices. If I have a method that will be executed many times a second; public static IQueryable<IPerson> InRadius(this IQueryable<IPerson> query, Coordinate center, double radius) { return (from u in query where CallHeavyMathFormula(u, center, radius) select u); } This extension method for IQueryable generates a SQL that does some heavy maths calculation (Cosine, Sine, etc). This would mean the application sends 1-2KB of sql to the server per call. I've heard of placing all application logic, in your application. I also would like to change to a database such as azure or one of those scalable databases in the future. How do I handle something like this? Should I leave it as it is now or write stored procedures? How do applications like twitter or facebook do it?

  • amp is included in url struts tag

    - by lakshmanan
    Hi, In my web application, I use strust2 url tag to pass parameters like id etc., For example, I use a link to delete an entity and I use param to pass the id of the entity to be deleted. And I follow this throughout my web app for adding, editing, deleting an entity. During run time, sometimes, I don't get the params to be stored in my action's bean properties. When I see the link that is generated, I get something like <a href='/projit1/p/discuss/viewDiscussion.action?d=11&amp;amp;amp;projid=11&amp;amp;disid=4'> What are these amps for ? why do they sit in between the action calls (made by link via url tag actions ) ? By the time I traverse back and forth in my web app, I get 10s and 20s of amp sitting in the request URL. What is the problem here ? Please help.

  • Special characters incongruence

    - by Enrique
    Hello I'm building a Spring MVC web application that runs on Tomcat 6.0.20 and JDK 1.6.0_19. When I send some special characters through an HTML form some of them are stored as question marks ? For example these symbols are stored correctly: €, á, é, í, ‰, etc But some symbols are replaced with ? like: £, ?, ? MySQL tables charset is utf-8. My jsp also use utf-8 <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %> I have included org.springframework.web.filter.CharacterEncodingFilter in web.xml as suggested here When I debug the POST request when sending 3 characters €a£ with firebug I get: %E2%82%ACa%E2%82%A4 which is correct since E2 82 AC is the code for € and E2 82 A4 is the code for £ but £ is stored as ? in the database. When I save £ directly into the database it is displayed correctly in the webpage. How can I fix this?

  • MS SQL Server Job with precise timing

    - by TcKs
    Hi, I have a DB with game data (map, players, etc...) and I have a game core mechanics writen in T-SQL stored procedure. I need process game loop (via the stored procedure) every "X" seconds. I tried used the SQL Job, but when I set the interval to seconds, the SQL server stops responding. If I set the interval greater than one minute, all was ok. I need game loop precise in time, e.g. the game loop will run only once and will be executed every "X" precisely (tolerance should be less than one second). Can I do it with MS SQL Server capabilities? Or should I create a windows service which will repeatly execute game loop procedure? Or should I go another way? Thanks! EDIT: The game loop stored procedure takes less than the interval.

  • Architectural Design for a Data-Driven Silverlight WP7 app

    - by Rosarch
    I have a Silverlight Windows Phone 7 app that pulls data from a public API. I find myself doing much of the same thing over and over again: In the UI, set a loading message or loading progress bar in place of where the content is Get the content, which may be already in memory, cached in isolated file storage, or require an HTTP request If the content can not be acquired (no network connection, etc), display an error message If the content is acquired, display it in the UI Keep the content in main memory for subsequent queries The content that is displayed to the user can be taken directly from a data source, such as an ObservableCollection, or it may be a query on a data source. I would like to factor out this repetitive process into a framework where ideally only the following needs to be specified: Where to display the content in the UI The UI elements to show while loading, on failure, and on success The URI of the HTTP request How to parse the HTTP response into the data structure that will kept in memory The location of the file in isolated storage, if it exists How to parse the file contents into the data structure that will be kept in memory It may sound like a lot, but two strings, three FrameworkElements, and two methods is less than the overhead that I currently have. Also, this needs to work for however the data is maintained in memory, and needs to work for direct collections and queries on those collections. My questions are: Has something like this already been implemented? Are my thoughts about the topic above fundamentally wrong in some way? Here is a design I'm thinking of: There are two components, a View and a Model. The View is given the FrameworkElements for loading, failure, and success. It is also given a reference to the corresponding Model. The View is a UserControl that is placed somewhere in the UI. The Model a class that is given the URI for the data, a method of how to parse the data, and optionally a filename and how to parse the file. It is responsible for retrieving the data and notifying the View whenever the current status (loading/fail/success) changes. If the data downloaded from the network is different from the cache, the network data takes precedence. When the app closes or is tombstoned, the model writes the data to the cache. How does that sound?

  • Are there any frameworks for data subscription and update?

    - by Timothy Pratley
    There is one server with multiple clients. The clients are viewing subsets of the servers entire data. If the data that a client is viewing changes, the client should be informed of the changes so that it displays the current data. Example: Two clients are viewing a list of users in an administration screen. One client adds a new user to the list and modifies the permissions of another user. The other client sees the changes propagated to their view.

  • Does it make sense to have a model with only static methods?

    - by Jamie Dixon
    Hey everyone, I have an ASP.NET MVC 2 project that I'm working on and I'm wondering where I should place some of my code. I currently have a UsersModel which consists of a bunch of static methods that operate against my data context. These methods include such things as: UserExistsInDatabase, UserIsRegisteredForActivity, GetUserIdFromFacebookId etc etc. Should these methods be inside a UsersModel class or would they be more suited to a user helper class outside of the models context? Cheers for any pointers.

  • guide on crawling the entire web ?

    - by bohohasdhfasdf
    i just had this thought, and was wondering if it's possible to crawl the entire web (just like the big boys!) on a single dedicated server (like Core2Duo, 8gig ram, 750gb disk 100mbps) . I've come across a paper where this was done....but i cannot recall this paper's title. it was like about crawling the entire web on a single dedicated server using some statistical model. Anyways, imagine starting with just around 10,000 seed URLs, and doing exhaustive crawl.... is it possible ? I am in need of crawling the web but limited to a dedicated server. how can i do this, is there an open source solution out there already ? for example see this real time search engine. http://crawlrapidshare.com the results are exteremely good and freshly updated....how are they doing this ?

  • How to evaluate "enterprise" platforms?

    - by Ran Biron
    Hi all, I'm tasked with evaluating an "enterprise" platform for the next-gen version of a product. We're currently considering two "types" of platforms - RAD (workflow engine, integrated UI, small cores of "technology plugins" to the workflows, automatic persisting of state...) like SalesForce.com / Service-Now.com and "cloud based" (EC2 / AppEngine...). While I have a few ideas on where to start, I'd like your opinions - how would you evaluate platforms for an enterprise suite of products? What factors would you consider? How would you eliminate weak options quickly enough to be able to concentrate on the few strong ones? Also interesting is how would you compare enterprise RAD (proven technology, quick to develop - but tends to look "the same as the competition") to cloud-based technology (lots of "buzz", not that many competitors - easy to justify to management, but probably lacking (?) enterprise tools and experience). As said before - I have a few ideas, but would like to see some answers before I post mine so I wouldn't drive the discussion to a specific place. RB.

  • Application that depends heavily on stored procedures

    - by PieterG
    We currently have an application that depends largely on stored procedures. There is a heavy use of temp tables. It's an extremely large application. Facing this situation, I would like to use Entity Framework or Linq2Sql for a rewrite. I might consider using Fluent Hibernate or Subsonic, as i've used them quite extensively in the past. I've had problems with Linq2Sql generating the return types for the stored procedures because of the usage of the temp tables, and I think it's cumbersome to go and change all the stored procedures from temp tables to in-memory tables. Considering the 2 choices that I want to make, which one of the 2 is the best route to go and why? If my choices are extremely idiotic, please provide alternatives. Edit: The reason for the question and the change is that the data access layer is non-existent and was built 10 years ago. We currently still run into a lot of issues with it. I don't want to divulge too much, but if you saw it, your eyes would start bleeding :)

  • Where should I define Enums?

    - by Ciel
    Hi: I'm setting up a new app, with a Repository layer/assembly, a Services layer/assembly, and a UI assembly. So I end up with namespaces such as: App.UI App.Biz.Services App.Data.Repositories And then I have enums for the args that are used by all 3 layers. Only place that makes sense is to put them in the Cross cutting assembly. (define them in Data layer too low, as UI should have no direct ref to them, defined in Services, too high for Repository layer, which shouldn't be referencing upwards). But...which namespace in Common? Namespaces should mostly be used to define concerns, rather than Type... I've always used something like: namespace App.Common.Enums {...} but it's always felt a bit of a hack that works for me, but not well in a large org where everybody is generating Enums, and if we put them all in Enums folder it's going to make the code folder harder to understand later. Any suggestions?

  • First Time Architecturing?

    - by cam
    I was recently given the task of rebuilding an existing RIA. The new RIA that I've designed is based on Silverlight, with a WCF service to connect to MS SQL Server. This is my first time doing something like this, so I'm not sure how to design the entire thing. Basically, the client can look through graphs of "stocks" (allowing the client to choose different time periods, settings, etc). I've written the whole application essentially, but I'm not sure how to put it together. The graphs are supposed to be directly based on the database, and to create the datapoints on the graph, some calculations need to be done (not very expensive ones). The problem I'm having is to decide where to put the calculations (client or serverside? Or half and half?) What factors should I look for to help me decide where the calculations should be done? And how can I go about optimizing this (caching, etc)? Obviously this is a very broad subject, so I'm not expecting an immediate answer, but any help/pointing in the right direction/resources would be appreciated.

  • Advantages of using WCF to work with Sharepoint Services WSS3.0?

    - by val
    Hi folks, what is your opinion or better off your practical experience using WCF to work with WSS instead of SP web services? I am writing some custom library for our software to store and retrieve files from WSS document libraries using sharepoint web services. I am not entirely happy with the performance of the sp web services - a bit too slow in many cases. Now, microsoft claims a significant improvements in WCF over remoting and I am looking into a good way to use WCF for my file services. Any suggestions or ideas? Maybe a good source of coding practices or blogs? Thanks a lot, Val

  • What is the cost of object creating.

    - by Tony
    Hi If I have to choose between static method and creating an instance and use instance method, I will choose static methods always. but what is the detailed overhead of creating an instance? for example I saw a DAL which can be done with static classes but they choose to make it instance now in the BLL at every single call they call something like. new Customer().GetData(); how far this can be bad? Thanks

  • Should I have one dll or multiple for Business Logic?

    - by Brian
    In my situation, my company services many types of customers. Almost every customer requires their own Business Logic. Of course, there will be a base layer that all business logic should inherit from. However, I'm going back and forth on architecting this--either in one dll for all customers or one dll for each. My biggest point of contention deals with upgrading the software. We have about 12 data entry personnel that work with 20 companies and it's critical that they have little down time. My concern is that if I deploy everything in one dll, I could introduce a bug in company A's logic while only intending to update Company B's logic. I believe I could reduce the risk if each company's logic had their own dll, so then, I could deploy Company B's update w/o harming Company A's. -- I will be the only one supporting this. That said, this also seems like a nightmare to manage 20 different .dll's -- that's for the BLL alone. I also need to create a View layer and ViewModel layer. So, potentially, I could have 20 (companies) * 3 (layers) which would equate to 60 .dll's. Thank You.

  • How is fseek() implemented in the filesystem?

    - by pajton
    This is not a pure programming question, however it impacts the performance of programs using fseek(), hence it is important to know how it works. A little disclaimer so that it doesn't get closed. I am wondering how efficient it is to insert data in the middle of the file. Supposing I have a file with 1MB data and then I insert something at the 512KB offset. How efficient would that be compared to appending my data at the end of the file? Just to make the example complete lets say I want to insert 16KB of data. I understand the answer varies depending on the filesystem, however I assume that the techniques used in common filesystems are quite similar and I just want to get the right notion of it.

  • Developing web app, question for mobile developers

    - by Stephen Kellett
    I'm going to develop a web app that I expect some people will also end up wanting to view on their phones. The UI will be fairly straightforward (no frames, just CSS/HTML). May have a bit of Flash, but not for the first version. My question is, for testing viewing of the web app on mobile devices what devices would you recommend that I test on (and thus, most likely, have to purchase)? Windows Mobile iPhone Android Other? or can I use emulators for any/all of these? Note that I'm not developing a platform (android, iPhone) specific app, just a web application that I expect will also be accessed from a mobile phone. I apologise if this seems like a niave/stupid question, but this hobby project is totally away from my commercial experience and I just don't know the answers to these questions, hence asking here. Thanks for reading.

  • Connection between Properties of Entities in Data Oriented Design

    - by sharethis
    I want to start with an example illustrating my question. The following way it is done in the most games. class car { vec3 position; vec3 rotation; mesh model; imge texture; void move(); // modify position and rotation void draw(); // use model, texture, ... }; vector<car> cars; for(auto i = cars.begin(); i != cars.end(); ++i) { i->move(); i->draw(); } Data oriented design means to process the same calculation on the hole batch of data at once. This way it takes more advantage out of the processor cache. struct movedata { vec3 position; vec3 rotation; }; struct drawdata { mesh model; imge texture; }; vector<movedata> movedatas; vector<drawdata> drawdatas; for(auto i = movedatas.begin(); i != movedatas.end(); ++i) { // modify position and rotation } for(auto i = drawdatas.begin(); i != drawdatas.end(); ++i) { // use model, texture, ... } But there comes a point where you need to find other properties according to an entity. For example if the car crashes, I do not need the drawdata and the movedata any more. So I need to delete the entries of this entity in all vectors. The entries are not linked by code. So my question is the following. How are properties of the same entity conceptually linked in a data oriented design?

If the data that a client is viewing changes, the client should be informed of the changes so that it displays the current data. Example: Two clients are viewing a list of users in an administration screen. One client adds a new user to the list and modifies the permissions of another user. The other client sees the changes propagated to their view. In the client side code I would like the users list to be updated by the framework itself, raising changed events such that it will be redrawn - similar to 'cells' or dataflow. I am looking specifically for a .NET or java implementation.
