  • What are some interesting fringe programming topics that might have hands-on training?

    - by hal10001
    Whenever training topic questions are asked, the answers are fairly typical, and involve a pretty limited subset of topics like OO, design patterns, algorithms, web services, SQL, etc., but I wonder if there are some fringe topics that are still applicable to the programming field and would give me a more rounded approach to development. When I think of "fringe", I think of 2600: The Hacker Quarterly articles that discuss how to use real world (sometimes obscure) exploits, or something like Maker Faire that demonstrates embedded systems programming using Arduino. I have around $1500-2000 to spend, and my job entails Java technologies, but that does not limit my options.

  • Pure Actionscript 3 Adobe Air Application main class constructor not being called

    - by SilverCode
    I'm writing an Air application using only Actionscript, and Flex3 SDK as the compiler. Everything compiles and runs fine under adl, but when the final air file is built and installed, the main class is never initialized. For instance: package { import flash.display.Sprite; public class main extends Sprite { public function main() { trace("Init"); } } } When run under ADL, "Init" will be output to the console, but when installed and run, nothing happens (the constructor for class main is never called).

  • Java: Using Comman line arguments to process the names of files

    - by Kat
    I'm a writing a program that will determine the number of lines, characters, and average word length for a text file. For the program, the specifications say that the file or files will be entered as a command line argument and that we should make a TestStatistic object for each file entered. I don't understand how to write the code for making the TestStatistic objects if the user enters more than one file.

  • Best practices book for CRUD apps

    - by Kevin L.
    We will soon be designing a new tool to calculate commissions across multiple business units. This new compensation scheme is pretty clever and well thought-out, but the complexity that the implementation will involve will make the Hubble look like a toaster. A significant portion of the programming industry involves CRUD apps; updating insurance data, calculating commissions (Joel included) ...even storing questions and answers for a programmer Q&A site. We as programmers have Code Complete for the low-level formatting/style and Design Patterns for high-level architecture (to name just a few). Where’s the comparable book that teaches best practices for CRUD?

  • Any serious problems when making an old java web app run on new IE 8 browser?

    - by pinichi
    I need make an quick estimation on project (not sure we got): It's an old banking CMS java web app: Server: jdk5, weblogic 9. Client: winXP, Ie6. It was design only for use with ie6 but now we need make it also run well on new client: ie8,ie7 on win7. I understand the most difference is the client: DOM and CSS. But my problem is we hasn't been worked with ie8, and I have not enough time to build an testing environment because our developing environment is not ready to make test (its remoting completely, and managed by another partner) Any experience or suggestion to help me weighing this task need will be welcomed.

  • Protect .NET code from reverse engineering?

    - by Priyank Bolia
    Obfuscation is one way, but it can't protect from breaking the piracy protection security of the application. How to make sure that the application is not tampered with, and how to make sure that the registration mechanism can't be reverse engineered. Also it is possible to make to convert C# app in native code, Xenocode is too costly. C# provides lot of features, and is the ideal language for my code, so writing in C++ again the whole codebase is out of question. Secure certificates can be easily removed from the signed assemblies in .NET

  • What should be owner type of a routed command?

    - by viky
    I am using wpf Custom Commands. While writing a custom Command, you need to define the owner type. Description says that it is the type that is registering the command. I was seeing some sample and there the Owner type was UIElement and in some others it was the class name itself. Whats the difference? What should be the owner type?

    I'm working on a project with a friend that will utilize Hbase to store it's data. Are there any good query examples? I seem to be writing a ton of Java code to iterate through lists of RowResult's when, in SQL land, I could write a simple query. Am I missing something? Or is Hbase missing something?

  • Opt-out of copy constructor

    - by sheepsimulator
    This might be a silly question, but... I've been writing a number of classes that utilize non-copyable members. These classes are never initialized via the copy constructor in my source. When I try to compile without supplying my own copy-constructor, g++ throws out many errors about how it can't build a default copy constructor, due to the non-copyable member objects. Is there a way to tell the compiler to just not give me a copy constructor?

  • Google Maps API V3 and stringByEvaluatingJavaScriptFromString?

    - by Joseph
    Hi, I'm writing up an iPhone app using the Google Maps API V3, and I was wondering if it is still possible the use the stringByEvaluatingJavaScriptFromString function in the (void)webViewDidFinishLoad:(UIWebView *)webView function? A simple example being changing the map type (Assuming basic map setup): - (void)webViewDidFinishLoad:(UIWebView *)webView{ [webView stringByEvaluatingJavaScriptFromString:@"map.setMapTypeId(google.maps.MapTypeId.SATELLITE);"];} This was very possible the the 2.0 API, but I can't seem to get it right in the 3.0 API. Any insight would be much appreciated.

  • Finding a pattern within a string variable in C#

    - by lo3
    Ok i'm working on a project for a 200 level C# course, we are required to create a heads or tails project. Basically the project is setup so that the computer will guess randomly up to 5 times, but on the sixth time it will look into the playersGuessHistory variable setup as a string to see if it can find a match for a pattern of 4 entires, if there is a pattern found the computer will guess the next character after the pattern EX: [HHTT]H [HHTTH]H HHTT being the pattern then the computer would guess H for the next turn. My only problem is that i'm having difficulty setting up the project so that it will look through the playersguesshistory and find the patterns and guess the next character in the history. Any suggestions?

  • Access Google Chrome's cache

    - by jldupont
    Is it possible to access Google Chrome's cache from within an extension? I'd like to write an extension that loads a cached version of a page when the online one can't be accessed (e.g. Internet connectivity issue). Updated: I know I could write an NPAPI plugin accessible through an extension to accomplish this but I'd rather not suffer writing one... I am after a solution without resorting to NPAPI, please.

  • realistically speaking, could a seasoned .net developer enter the java space and land a job?

    - by mrblah
    I've been working with .net since 2001, and I am considering making a move into the java space. I find that java has so many more mature tools (hibernate is more mature, spring framework, established patters/designs, containers, distributed cache frameworks, etc etc.) I have been doing .net, and just recently I have been getting into design patterns, ORMS, etc. and it just seems the .net side of things are not as mature. Yes the trend going forward looks great as more and more are getting into this design strategy etc. I don't want this to get into a flame war, but I read that its not about the framework/stack, but the tools around it are what make the difference. And to me Java seems to be the winner. Anyhow, the real question here is, could I realistically get into shape in 6 months? i.e. Someone would consider hiring me, and not at a junior dev pay rate? Is this a bad idea?

  • Problem with GetDefaultPrinter() over a VPN c++

    - by Ian Crowder
    I am writing an application that gets its dimensions from the paper ratio of the default printer of the local computer. This all works well unless the default printer is over a VPN. When this is the case, calling GetDefaultPrinter() takes too long. I need to find a way to put a time constraint on GetDefaultPrinter() and if it exceeds that constraint, break out of the function. Any possible solutions would be great. Thanks, Ian
