  • PyPy: What is all the buzz about?

    - by sub
    Note: The title is provocating (to make you click on it and want to close-vote the question) and I don't want to look preoccupated. Since some time now I read and heard more and more about PyPy. It's like a linear graph. Why is PyPy so special? As far as I know implementations of dynamic languages written in the languages itself aren't such a rare thing, or am I not getting something? Some even people call PyPy "the future" [of python], or see some sort of deep potential in this implementation. What exactly is the meaning of this?

  • Recommendation for a Pagination procedure AJAX PHP

    - by Jamex
    Hi, I am not sure the correct terminology for the process that I am trying to describe. I don't even know which platform is underlying the technique. If you understand my description, please give the link to the site(s) and or the keyword name of the process. I think it is done by AJAX, but I am not certain. I use php as the backend code, I just need to find a way to dynamically display the results. Please give suggestions. I forgot the name of the sites that use this, and my link history expired. TIA Description: The page would have a search form and options. After the user submits, the search is initiated, and the results appear inside the dedicated result area. The page does not refresh, just the info inside the result area. The display area will show 20 (or whatever) results (lines). There will be next, and previous buttons. If you hit next, the next set of results will display. I am writing a code that generates 20 results for each display. There is no set number of results, so the results might have a start/first page, but do not have an end page. Each time the user hits 'next', the program would generate/load new results. It would also store previous results, so that when a user hits 'prev', the previous results can instantly come up. What techniques/program are theses?

  • Pass an event into a constructor

    - by Vaccano
    I have a class that I want to be able the handle the mouse up event for a grid. I tried to create it with a static method call like this: MyDataBinding.BindObjectsToDataGrid(ListOfObjectsToBind, myGrid.MouseUp); The end goal being that in the method I would assign a delegate to the MouseUp PassedInMouseUp += myMethodThatWillHandleTheMouseUp; Looks good here (to me) but the compiler chokes on the first line. It says that I can only use MouseUp with a += or a -=. Clearly I am going about this the wrong way. How can I get a different class to handle the mouse up with out having to: Pass in the whole grid Expose the method that will be handling the mouse up as a public method. Or, is this just a limitation and I will have to do one of the above?

  • In C# should I reuse a function / property parameter to compute cleaner temporary value or create a

    - by Hamish Grubijan
    The example below may not be problematic as is, but it should be enough to illustrate a point. Imagine that there is a lot more work than trimming going on. public string Thingy { set { // I guess we can throw a null reference exception here on null. value = value.Trim(); // Well, imagine that there is so much processing to do this.thingy = value; // That this.thingy = value.Trim() would not fit on one line ... So, if the assignment has to take two lines, then I either have to abusereuse the parameter, or create a temporary variable. I am not a big fan of temporary variables. On the other hand, I am not a fan of convoluted code. I did not include an example where a function is involved, but I am sure you can imagine it. One concern I have is if a function accepted a string and the parameter was "abused", and then someone changed the signature to ref in both places - this ought to mess things up, but ... who would knowingly make such a change if it already worked without a ref? Seems like it is their responsibility in this case. If I mess with the value of value, am I doing something non-trivial under the hood? If you think that both approaches are acceptable, then which do you prefer and why? Thanks.

  • Sending MMS into different Android devices

    - by 6istik
    I need to send MMS. Into my hero this code looks ugly but works: Intent sendIntent = new Intent("android.intent.action.SEND_MSG"); sendIntent.putExtra("address", toText); sendIntent.putExtra(Intent.EXTRA_SUBJECT, "subject"); sendIntent.putExtra("sms_body", textMessage); sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(url)); sendIntent.setType("image/jpeg"); startActivity(sendIntent); But it seems to me that on the other devices it doesn't work at all. I want to send directly to main messaging app without any choices(the better solution of course - direct from my app). Because not sure that all of them would handle it properly. If anybody could recommend any third-party library I'll be appretiate.

  • [Ruby] Confirm existance of executable (script, bat, cmd, exe) via a ruby file.

    - by srcspider
    Using a ruby file (or any rake facility) I need to find out if the user who executes my script is able to execute certain shell commands. In particular g++ etc. Hopefully system independent so if there is some g++.bat, g++.exe or just g++ (etc) it should say yes nevertheless, as long as its on the path and executable on the users system. Example: if the user has a no-extention executable version of the file and a .cmd version of the file it should say "yes" for the no extension version on a linux system and "yes" to the .cmd version on a windows system. Since the users shell can only execute that version of the file. The purpose of this is to allow the script to be self-configuring (as much as possible). Any suggestions on how I might go about doing this?

  • Simple but good pattern for EJB

    - by Sara
    What would you suggest as a good and practical but simple pattern for a soloution with: HTML + JSP (as a view/presentation) SERVLETS (controller, request, session-handling) EJB (persistence, businesslogic) MySQL DB And is it necessary to use an own layer of DAO for persistence? I use JPA to persist objects to my DB. Should I withdraw business logic from my EJB? Sources online all tell me different things and confuses me...

  • Struts for IBM Application Server Toolkit

    - by Timbuck
    I'm looking to build a Struts 1.2.x application for Websphere, using IBM's Application Server Toolkit. Are there any plugins available for this toolkit (it is a version of Eclipse) that are known to help with this type of development? I am new to Struts so I will also be learning about the technology as I go along, but I want to make it as painless as possible. A web search has only brought up things such as "MyEclipse", which I can't use in the corporate environment.

  • Remoting connection over TCP

    - by Voyager Systems
    I've got a remoting server and client built. The server is set up as such: BinaryServerFormatterSinkProvider serverProv = new BinaryServerFormatterSinkProvider(); serverProv.TypeFilterLevel = TypeFilterLevel.Full; BinaryClientFormatterSinkProvider clientProv = new BinaryClientFormatterSinkProvider(); IDictionary props = new Hashtable(); props["port"] = port; TcpChannel channel = new TcpChannel( props, clientProv, serverProv ); ChannelServices.RegisterChannel( channel, false ); RemotingConfiguration.RegisterWellKnownServiceType( typeof( Controller ), "Controller", WellKnownObjectMode.Singleton ); The client is set up as such: ChannelServices.RegisterChannel( new TcpChannel( 0 ), false ); m_Controller = (Controller)RemotingServices.Connect( typeof( Controller ), "tcp://" + ip + ":2594/Controller" ); When I try to connect to the server from the same computer with the IP specified as 'localhost,' it connects fine. However, when I try to connect from a remote computer, not on the LAN, given the server's IP address, I receive the following exception on the client after a long wait: A connection attempt failed because the connected party did not properly respond after a period of time How can I resolve this? I'm sure it's a configuration problem because the ports are forwarded properly on the server and there is no firewall active. Thanks

  • vb6 ADODB TSQL procedure call quit working after database migration

    - by phill
    This code was once working on sql server 2005. Now isolated in a visual basic 6 sub routine using ADODB to connect to a sql server 2008 database it throws an error saying: "Login failed for user 'admin' " I have since verified the connection string does work if i replace the body of this sub with the alternative code below this sub. When I run the small program with the button, it stops where it is marked below the asterisk line. Any ideas? thanks in advance.

  • CakePHP: Can I ignore a field when reading the Model from the DB?

    - by Daniel Magliola
    In one of my models, I have a "LONGTEXT" field that has a big dump of a bunch of stuff that I never care to read, and it slows things down, since I'm moving much more data between the DB and the web app. Is there a way to specify in the model that I want CakePHP to simply ignore that field, and never read it or do anything with it? I really want to avoid the hassle of creating a separate table and a separate model, only for this field. Thanks! Daniel

  • Google maps api Directions User defined Steps

    - by Via Lactea
    Hi All, I have a google map service with the stores mapped on it. I also have directions service (then you define two addresses or more and it shows you a way on this map, see google map api directions). So I wa?? to show the nearest stores to this way. Of course it could be the store located in the next streat of my way, so it also should be included to the list. So far I just found only an array of steps in the directions object which I get from google maps api. But these steps are predefined by google, so they can be too close one each to other and they also can be too far (if a part of your route is a highway or there is no any special steps on your way etc.) So, what I want to do. I want to make my own steps on the line that I get from google directions (for example to put these steps on my line every 500 meeters etc.), and after that to search every step for any stores around 200 meeters. Is it possible to do? I cannot find any solution of this idea in internet.

  • Storing User Information in Session with aspNetMembershipProvider

    - by Muhammad Adeel Zahid
    Hi Everyone, i m developing an application in .NET mvc2. i m using aspnetMembershipProvider for User registration and related activities. i need some custom information about user that i stored in a separate table (sysUser for example) and linked it to aspnetUser table through foreign key. after Login i need to fetch user's credentials from sysUser table and push it to the session. For this Account controller's Logon method seemed best to me and i pasted following code in my Logon ActionResult if (!ValidateLogOn(userName, password)) { return View(); } FormsAuth.SignIn(userName, rememberMe); ApplicationRepository _ApplicationRepository = new ApplicationRepository(); MembershipUser aspUser = Membership.GetUser(userName); SessionUser CurrentUser = _ApplicationRepository.GetUserCredentials(aspUser.ProviderUserKey.ToString()); //Session["CurrentUser"] = CurrentUser; if (!String.IsNullOrEmpty(returnUrl)) { return Redirect(returnUrl); } else { return RedirectToAction("Index", "Home"); } The code is working perfectly for me and put my desired information in the session but the thing is that if a user selects Remember me and on his next visit he won't have to Log in and i would not find my desired information in the Session. Can anyone guide me where should i put my code that stores the user information in the session. any Help is Highly appreciated Regards Adeel
