  • Why does does my stack overflow error occur after 518669 specifically?

    - by David
    I created a java program to count up toward infinity: class up { public static void up (int n) { System.out.println (n) ; up (n+1) ; } public static void main (String[] arg) { up (1) ; } } i didn't actually expect it to get there but the thing that i noticed that was a bit curious was that it stopped at the same number each time: 518669 what is the significance of this number? (or of this number +1 i suppose). (also as a bit of an aside question, I've been told that the way i format my code is bad [indentation and such] what am i doing that isn't desirable?)

  • Teach Perl as a first language?

    - by yossale
    I need to teach a non-programmer the basics of computer programming + some basic programming skills (- He's going to be in a position between the clients and the programmers , so the company requires him to learn the basic concepts of programming). I thought of Perl - You can teach it without getting into typing and pointers and it's syntax is very close to human (precious "bless" :) ) - but I'm a bit troubled because I feel like I'm going to "spoil" him for other languages in the future (C,C++,Java - What some people call "Real" languages) - exactly because of the reasons mentioned above. What do you think?

  • Should I use Google Web Toolkit for my new webapp?

    - by balint.miklos
    I would like to create a database backed interactive AJAX webapp which has a custom (specific kind of events, editing) calendaring system. This would involve quite a lot of JavaScript and AJAX, and I thought about Google Web Toolkit for the interface and Ruby on Rails for server side. Is Google Web Toolkit reliable and good? What hidden risks might be if I choose Google Web Toolkit? Can one easily combine it with Ruby on Rails on server side? Or should I try to use directly a JavaScript library like jQuery? I have no experience in web development except some HTML, but I am an experienced programmer (c++, java, c#), and I would like to use only free tools for this project.

  • Is there a jdbc driver for SQL Server that can search for database instances on network?

    - by djangofan
    Is there a jdbc driver for SQL Server that can search for database instances on network? Just wanting to emulate "OSQL -L" from the JDBC driver. Dont want to have to call OSQL from JNI or something. I also don't want to have to write my own code for scanning a UDP port. I want my Java application to be able to search for live SQL Servers and prompt me with a list of available servers. Isn't this a reasonable expectation for a JDBC driver? OSQL.exe can do it and so why not the JDBC driver?

  • All possible combinations of n items selected randomly from a set of x items (algorithm)

    - by SubPortal
    I have a set of x string items e.g("A","B","C","D","E","F") I need to know the formula that calculates how many combinations of n items and what is the algorithm that generates all possible combinations e.g if we need to select 4 items from the list randomly. those 4 items could be: ("A","B","C","D") or ("A","B","C","E") or ("A","B","C","F") or ("A","B","D","E") ...etc I need the formula that calculates how many sets of items will be generated without repetition, that is we consider ("A","B","C","D") as one of the resulted combinations we cannot consider the same items as another resultant combination with replacing the positions of the items in the set like ("A","B","D","C") Also I need the algorithm that generates all possible combinations in any programming language. [C#,VB.NET,Java,C++] Thank you for any help.

  • Execute PHP without leaving page

    - by Dylan Taylor
    Okay. I have a form - textarea (named "su") and submit button. When the form is submitted, I need to run a PHP script without refreshing/leaving page "echo" or somehow print a return on the screen I'm pretty sure this works via some kind of ajax request thing. but I have no idea what I'm talking about. I'm not big on ajax or javascript, but this is a function i use very frequently and I'd like to learn how it works so I can implement it when i need to now and in the future. Like i said I'm uneducated with ajax or java. a quick example would be wonderful. thanks for taking the time to read!

  • How to turn on Mercurial in existing Eclipse project ?

    - by Rabarberski
    I've installed the HgEclipse plugin for Mercurial integration in Eclipse. I have an existing (Java) project in Eclipse, but I can't figure out how to turn on mercurial change tracking for this existing project. It seems I can do an import of a mercurial project (File Import Mercurial Clone ...), but that's only for new Eclipse projects... Of course, I can apply Mercurial via the command line, e.g. hg init in the project directory, but this doesn't get picked up in Eclipse. So, how do I turn on Mercurial for existing Eclipse projects?

  • Eliminating code duplication in a single file

    - by Jon
    Sadly, a project that I have been working on lately has a large amount of copy-and-paste code, even within single files. Are there any tools or techniques that can detect duplication or near-duplication within a single file? I have Beyond Compare 3 and it works well for comparing separate files, but I am at a loss for comparing single files. Thanks in advance. Edit: Thanks for all the great tools! I'll definitely check them out. This project is an ASP.NET/C# project, but I work with a variety of languages including Java; I'm interested in what tools are best (for any language) to remove duplication.

  • GWT UIBinding cannot find zero-arg constructor

    - by aarestad
    I'm trying my hand at the new GWT 2.0 UIBinder capability, and I have a ui XML that looks like this: <ui:UiBinder xmlns:ui="urn:ui:com.google.gwt.uibinder" xmlns:g="urn:import:com.google.gwt.user.client.ui" xmlns:my='urn:import:com.mystuff.mypackage'> <g:VerticalPanel> <!-- other stuff --> <my:FileUploadPanel.ValidatingFileUpload styleName="field" ui:field="fileUpload" /> </g:VerticalPanel> ValidatingFileUpload is a non-static inner class contained in FileUploadPanel. It has an explicit zero-arg constructor that simply calls super(). However, when GWT starts up, I get this error: 00:00:18.359 [ERROR] Rebind result 'com.mystuff.mypackage.FileUploadPanel.ValidatingFileUpload' has no default (zero argument) constructors. java.lang.NoSuchMethodException: com.mystuff.mypackage.FileUploadPanel$ValidatingFileUpload.<init>() Any idea what might be going wrong here?

  • Fire Fox 3.6 - location.href not working in JSP

    - by user299873
    I have jsp page with method = POST and action='/mydir/mypage/nextpage' I have a button : < button title='Continue' onclick="this.form.perform.value='cancelButton'; javascript:doCloseWindow();" Continue < /button and java script method like: function doCloseWindow(){ location.href = "https://abc.xyz.com/mydir/?param=123"; } It does not work in fire fox 3.6. On click of button; it redirects to the path I mentioned in form action. With Tamper data I find that the request goes to URL ( as in method ) with GET and then it re-directs to form's action URL. I added return false in the method call also.-- javascript:doCloseWindow();return false" I tired various combination like window.location.href = "https://abc.xyz.com/mydir/?param=123"; window.document.location.href = "https://abc.xyz.com/mydir/?param=123"; document.location.href = "https://abc.xyz.com/mydir/?param=123"; But no success.

  • Best Persistence API for use with GWT

    - by KevMo
    What is the best persistence API for use with GWT? Sadly, the application will be hosted on my own java server, as I will need more control than GAE will give me. I know I will need to have two sets of my entities, one for the server side, and some pojo's for the client side. I'm looking to make the mapping of the data as simple as possible between the two, but these will be deeply nested objects so it has to be robust. I was looking at Dozer for my mapping needs. Previously I've used EJB3 with TopLink, so that's very familiar to me, but I would like to get community input on what other API's work well with Dozer and GWT.

  • ASP.net Pop up Alert without page load

    - by Sunny
    Hi, In ASP.NET -- I want to popup an alert window in the case of an event. I don't have a button, i do not load the page at that event. When I searched i got a lot of java script examples but I can't use them as they work either on a button click or on page load. I just want a pop window to come as soon as I capture a particular event. I keep checking for the events every 5 second, as soon as i capture one event, there is a switch case for the actions to follow according to the event captured. For one particular case, i need one pop up "Sorry" along with an OK button. Can someone tell me what to do. Thanks

  • Must have JavaScript pro developer tools, libs, utilities and workshop configuration.

    - by WooYek
    This is a followup question to the Pro JavaScript programmer interview questions (with answers). What is considered professional and industrial standard for a professional browser side Java Script developer when it comes to his workshop configuration, and maybe from-concept-to-shipment process? What are the most popular IDE's, utilities and probably libraries, not limited to the free ones. These that can help cut development time (eg. IDE), help with achieve better quality (eg. unit testing tools), reliability and maintainability. I'm looking for a baseline to which I could compare potential candidates based on their ability to keep their tools sharp and workshop efficient (pro's should invest time&money in good tools, right?).

  • Testing harness for online teaching?

    - by candeira
    I have been asked to teach an online programming course, and I am looking for a test harness especially geared to education. Some students will have significant coding experience, but others will be total newbies. The course is an introduction to software development, mostly taught in C with some C++ and Java thrown in. In any case, I would like to read their source code only after a test suite has made sure that it compiles and executes properly. The students will also benefit from having a tool they can check their code against before submitting it. However, the Learning Management System my employer is using doesn't have such a system. Do you know of any LMS software that includes this feature? Which testing harness would you recommend in case I have to roll my own?

  • Maven problems using GAE and DataNucleus

    - by Wraith
    I'm having trouble retrieving 2 artifacts in my Maven/Java/Google App Engine project: com.google.appengine.orm:datanucleus-appengine:jar:1.0.7.final com.google.appengine:appengine-api-1.0-sdk:jar:1.3.4 There's a similar question posted, but each answer brings me back to the same error message. More detail I don't know if it is relevant, but rather than a version number, my original dependency for DataNucleus contained a variable. I am using Eclipse. <groupId>org.datanucleus</groupId> <artifactId>datanucleus-core</artifactId> <version>${datanucleus.version}</version> <scope>runtime</scope> I did not include my stack trace in Maven for brevity's sake. Please let me know if it would help to post it. Thank you.

  • MDE Access decrypt JDBC

    - by michelemarcon
    I want to perform JDBC SQL queries on a MDE Access file. I've set up the data source ODBC and everything worked well for a MDE file. Now, I'm working with a newer version of the MDE file, and here is the result: java.sql.SQLException: [Microsoft][Driver ODBC Microsoft Access] Cannont read record. Read authorization unavailable for "tbl_mytable". If I open the MDE with Access Runtime I am asked for a password, and after leaving a blank password I can see all the data. Of course, "tbl_mytable" does exist inside the database.

  • Can you recommend a .net template engine?

    - by serg10
    I am looking for a .net templating engine - something simple, lightweight, stable with not too many dependencies. All I need it for at the moment is creating templated plain text and html emails. Can anyone give me a good recommendation? If it helps at all - something like Java's Freemarker or Velocity libraries. [UPDATE] Thanks for the answers so far - much appreciated. I am really intested in recommendations or war stories from when you have used these libraries. Seems to be the best way to make a decision without trying each in turn.

  • asp.net mvc deployment

    - by Casey
    I've been dealing with a legacy asp.net 2.0 web site that was originally setup to deploy everything (source uncompiled) to the target server. I've been looking at doing some major upgrades and want to move to asp.net mvc. I'm coming from mostly a Java background where we typically deploy everything inside of a Web ARchive (war file) and the application server takes it from there. Is there a similar concept in the .net world? Right now in my mvc test app, I just put the compiled code into the deployed bin folder and the rest of the script/view files there as well. From what I have been reading it seems that most use the Publish feature of VS.

  • Hidden features of x86 assembly

    - by Earlz
    I am still a fan of x86 assembly(sorta) and know a lot of developers still using x86 assembly, although by far there are very few features available in assembly, let us list out the most useful and not so well known ones. Of course the question is on the lines of the Hidden Features questions listed below.: Hidden Features of JavaScript Hidden Features of CSS Hidden Features of C# Hidden Features of VB.NET Hidden Features of Java Hidden Features of ASP.NET Hidden Features of Python Hidden Features of TextPad Hidden Features of Eclipse Hidden Features of Classic ASP Please specify one feature per answer. Also, you can specify all bits of the x86 such as 16bit(real mode), 32bit, and 64bit. Please keep it neutral of assembler though. Both Intel and AT&T syntax is welcome but please don't for example demonstrate a useful macro feature for yasm.
