  • java applet - array checking

    - by Dan
    OK so my code is here: http://www.so.pastebin.com/m7V8rQ2n What I want to know... let's say I have an image which I can redraw on tiles... is there a way to check for future tiles so I DON'T go out of bounds of my already defined tile map? Like if I were at the edge of a map... it would NOT let me go past it? Thanks.

  • Will "Programming in the Cloud" Ever Take off?

    - by Pierreten
    Just got a chance to try out a cloud programming environment that let's you develop .net apps within the browser (http://coderun.com/ide/) I found it pretty interesting, since I was able to develop a mockup ASP.net site on an IPad. With javascript engines in browsers becoming faster and faster, cheap server infrastructure to compile on; will the cloud become the IDE platform of the future?

  • MYSQL autoincrement a column or just have an integer, difference?

    - by David19801
    Hi, If I have a column, set as primary index, and set as INT. If I don't set it as auto increment and just insert random integers which are unique into it, does that slow down future queries compared to autincrementing? Does it speed things up if I run OPTIMIZE on a table with its primary and only index as INT? (assuming only 2 columns, and second column is just some INT value) (the main worry is the upper limit on the autoincrement as theres lots of adds and deletes in my table)

  • Operator precedence in scala

    - by Jeriho
    I like scala's propose of operator precedence but in some rare case unmodified rules may be inconvenient because you have restrictions in naming your methods. Is there in scala ways to define another rules for a class/file/etc? If not would it be resolved in future?

  • Multithreaded java cache for objects that are heavy to create ?

    - by krosenvold
    I need a cache some objects with fairly heavy creation times, and I need exactly-once creation semantics. It should be possible to create objects for different CacheKeys concurrently. I think I need something that (under the hood) does something like this: ConcurrentHashMap<CacheKey, Future<HeavyObject>> Are there any existing open-source implementations of this that I can re-use ?

  • Do you know any mainstream desktop applications developed with Python and Qt?

    - by systempuntoout
    Hi i'm developing a small prototype of a desktop application using Qt and Python because i would like to distribute it in a multiplatform way. A friend of mine is annoying me on messenger because he claims that there are not known cool mainstream desktop apps developed with Qt and python technologies so, what i am doing, is just an exercise without future. Do you know any cool apps developed in python+Qt? thanks

  • How to do svn ignore on a single file?

    - by Zando
    I know it's a basic question but I've tried every combination of propedit propset, etc. In an existing project, there's a file (let's call it 'error.log) I want to ignore for all future commits. What's the command-line syntax to do so?

  • AbsoluteTime with an integer argument behaves strangely.

    - by dreeves
    This is strange: DateList@AbsoluteTime[596523] returns {2078, 7, 2, 2, 42, 9.7849} But DateList@AbsoluteTime[596524] returns {1942, 5, 26, 20, 28, 39.5596} The question: What's going on? Note that AbsoluteTime with an integer argument is undocumented. (I think I now know what it's doing but figured this is useful to have as a StackOverflow question for future reference; and I'm curious if there's some reason for that magic 596523 number.)

  • Is it possible to restrict how a method can be called in PHP?

    - by Ashley Ward
    Given that my class looks like this: class Methods{ function a(){ return 'a'; } function b(){ $this->a(); } function c(){ $this->a(); } } Is it possible to ensure that function a can only be called from function b? In the above example function c should fail. I could just include it in function b, but in the future I may want to let a() be called by some new functions (e.g. d() or e())

  • Xml with spaces as InnerText

    - by David Rutten
    I'm parsing Xml data which has entries like this: <item name="UserText" type_name="gh_string" type_code="10"> </item> I'm supposed to read the 6 spaces as a String, but both the InnerText and InnerXml values of the System.Xml.XmlNode are zero length Strings. Is there any way I can get at this whitespace data in existing files and what do I need to do in the future to prevent this sort of screw up?

  • Tracking user changes in ASP.NET MVC

    - by Ian Roke
    I have a requirement to track what authenticated users change with regards to the data when logged in. I don't need to track what pages they look at although that could be very useful in future. I have thought about saving the User Guid but that seems very clunky. Are there other methods/best practises?

  • Rails 3 beta 3 -- is it time to start using this for new projects?

    - by TMB
    Is it time to start new projects in Rails 3? I'm nervous about using beta versions but at the same time I really like what they are doing and don't want to deal with legacy 2.3.5 issues with these apps. Is it better to wait these things out, or buckle-up, deal with early adopter issues and get a head start on the future. Thanks for any light you can shed.

  • Is there an in memory database that supports the DATE function?

    - by Chris J
    Hi, I am doing some unit testing for a DAO that works with postgresql. Some of the SQL queries that my DAO uses involve the DATE function. Is there an in-memory database that supports functions similar to the ones that postgresql does? Currently I am looking for support for the DATE function however, I obviously can see myself using other functions in the future.

  • Which browsers support html5 offline storage?

    - by Marcin
    Essentially, I wanted to run a piece of demo code from W3c Offline Webapps page. It looks like that: var db = window.openDatabase("notes", "", "The Example Notes App!", 1048576); Firefox 3.5, IE8 and Chrome do not seem to get it. Is there anybody out there that actually wrote support for that? Or is this wishful thinking about 'the standard of the future'?

  • Overload with different return type in java?

    - by nunos
    So, I am just starting Java and, even though I have looked in some question about it here at stackoverflow.com and elsewhere, haven't been able to find a straightforward answer to why isn't possible to overload a function just by changing the return type. Why is it so? Will that provably change in a future version of Java? By the way, just for reference, is this possible in C++? Thanks.

  • Groups equivalent for social plugin Facepile

    - by oivvio
    I need to do something similar to the Facepile social plugin for a site I'm working on. The problem is the client does not have have a Facebook page, but instead has a Facebook Group (with some 4000+ members). I guess I could urge the client to move their group members to a page, and I might do that in the future. But before I do I want to research how we're going to do Facebook-integration more thoroughly. For now I just need a quick fix.

  • SQL Server: How to tell if a database is a system database?

    - by Vinko Vrsalovic
    I know that so far (until MSSQL 2005 at least), system databases are master, model, msdb and tempdb. Thing is, as far as I can tell, this is not guaranteed to be preserved in the future. And neither the sys.databases view nor the sys.sysdatabases view tell me if a database is considered as a system database. Is there someplace where this information (whether a database is considered a system database or not) can be obtained?
