  • How do I best catch up with the latest developments in java?

    - by Fredriku73
    I am applying for a job as java developer. I programmed some hobby apps in java until 2001, after that I have mostly worked in c++ and other languages. Meanwhile, it feels like java has grown a lot, and there are all kinds of acronyms (EJB, spring, etc) unknown to me. Where can I find a concise, clear explanation of the recent (5 years) development of java? What are key elements to understand?

  • How to make OSX application that just runs opens some file type and runs arbitrary Ruby code?

    - by taw
    It's trivial to make a program executable from shell - just put #!/usr/bin/ruby on top, chmod +x it and done. Unfortunately OSX won't let me associate file type with such scripts - it requires its .apps instead. This sort of distinction doesn't seem to exist on other operating systems. What's the simplest way of making such .app, which would merely execute some arbitrary Ruby code?

  • How to print structures in PLT Scheme so as to display their fields?

    - by tkf
    I would like code like this: (define-struct thing (a b c)) (define th (make-thing 1 2 3)) to print something like this: (make-thing 1 2 3) when I type "th" into either the DrScheme or MzScheme repl. I am using the language "pretty big" in DrScheme with output style set to "constructor". This is what I get in DrScheme: (make-thing ...) (i literally get the three dots) In MzScheme: #<thing>

  • <a> with an inner <span> not triggering :active state in IE

    - by Adam Singer
    I want to style the :active state of a button that is represented by an . The tag has an inner (beacuse I want to add an icon to this button). I notice the :active state is triggered properly in everything but Internet Explorer. In IE, it appears that the area around the (the 's padding) triggers that :active state, but when clicking directly on the text within the , the :active state is not triggered. Is there a way to fix this without resorting to Javascript?

  • Linking and Redirecting between multiple applications running under a single system folder

    - by Gurunandan
    I am running multiple applications with a single Codeigniter system/ folder using the recommended way on the Codeigniter wiki. Each application runs fine and I can link between apps using absolute URLs. Is there some way I can use or extend the URL helper class (functions like anchor(), redirect()... etc.) to generate links to controllers across applications. I would like to avoid absolute URLs Thanks!

  • Why is the recursion idiom in Haskell "'n+1' and 'n'" and not "'n' and 'n-1'"?

    - by rulfzid
    I'm working my way through Graham Hutton's Haskell book, and in his recursion chapter, he often pattern-matches on "n+1", as in: myReplicate1 0 _ = [] myReplicate1 (n+1) x = x : myReplicate1 n x Why that and not the following, which (1) seems functionally identical and (2) more intuitive in terms of understanding what's happening with the recursion: myReplicate2 0 _ = [] myReplicate2 n x = x : myReplicate2 (n-1) x Is there something I'm missing here? Or is it just a matter of style?

  • Suggestions In Porting ASP.NET to MVC.NET - Is storing SiteConfiguration in Cache RESTful?

    - by DaveDev
    I've been tasked with porting/refactoring a Web Application Platform that we have from ASP.NET to MVC.NET. Ideally I could use all the existing platform's configurations to determine the properties of the site that is presented. Is it RESTful to keep a SiteConfiguration object which contains all of our various page configuration data in the System.Web.Caching.Cache? There are a lot of settings that need to be loaded when the user acceses our site so it's inefficient for each user to have to load the same settings every time they access. Some data the SiteConfiguration object contains is as follows and it determines what Master Page / site configuration / style / UserControls are available to the client, public string SiteTheme { get; set; } public string Region { private get; set; } public string DateFormat { get; set; } public string NumberFormat { get; set; } public int WrapperType { private get; set; } public string LabelFileName { get; set; } public LabelFile LabelFile { get; set; } // the following two are the heavy ones // PageConfiguration contains lots of configuration data for each panel on the page public IList<PageConfiguration> Pages { get; set; } // This contains all the configurations for the factsheets we produce public List<ConfiguredFactsheet> ConfiguredFactsheets { get; set; } I was thinking of having a URL structure like this: www.MySite1.com/PageTemplate/UserControl/ the domain determines the SiteConfiguration object that is created, where MySite1.com is SiteId = 1, MySite2.com is SiteId = 2. (and in turn, style, configurations for various pages, etc.) PageTemplate is the View that will be rendered and simply defines a layout for where I'm going to inject the UserControls Can somebody please tell me if I'm completely missing the RESTful point here? I'd like to refactor the platform into MVC because it's better to work in but I want to do it right but with a minimum of reinventing-the-wheel because otherwise it won't get approval. Any suggestions otherwise? Thanks

  • iPhone to Android Market

    - by BahaiResearch.com
    (I am coming from an iPhone experience) When we create an iPhone app, Apple gives us a http URL that we can put on web pages that when clicked will open iTunes and give the user a chance to buy on their desktop. As Android has no "iTunes" Windows/Mac application on the desktop, what do I link to on my Web pages/email marketing so that users can go and buy the Android apps we are writing? Ian

  • Is there a max size for POST parameter content?

    - by l3dx
    I'm troubleshooting a java app where XML is sent between two systems using HTTP POST and a servlet. I suspect that the problem is that the XML is growing way to big. Is it possible that this is the problem? Is there a limit? When it doesn't work, the request.getParameter("message") on the consumer side will return null. Both apps are running on tomcat

  • Nonblocking io webserver/framework for java

    - by SeekingNonblockingIo
    Does anyone know of any node.js style webserver framework for java? I realized that having nonblocking callback behavior while handling a web request will require deep support at the webserver level. I am interested in node.js, but when I have a web server that ends up persisting data, I would like to take advantage of the static type system that Java offers. However, I want the scalability of non-blocking io.

  • How do I keep my app from tracking bot requests as views

    - by trustfundbaby
    This is a general question about writing web apps. I have an application that counts page views of articles as well as a url shortner script that I've installed for a client of mine. The problem is that, whenever bots hit the site, they tend to inflate the page views. Does anyone have an idea on how to go about eliminating bot views from the view count of these applications?

  • Audio Streaming API's: Wifi vs what?

    - by Moshe
    I've noticed certain radio apps, that some stations required wifi and others did not. What were those other stations possibly using? Are there other methods of streaming audio on iOS? Apparently, I was not clear in my question before. I'm asking in terms of API's. Is there an API to interact directly with say, FM radio, on iOS? Is wifi the only way of streaming audio?
