  • silverlight 4 net tcp binding security

    - by SLfan
    This document talks about how to send username and password from SL4 app to a web service. It assumes that HTTPS will be used for transport. However, I want to use NET TCP because of its speed. Is that possible because another article says net tcp in SL4 does not provide transport level security. If that's incorrect then how do I convert the https implementation to net tcp?

  • Getting the name of a Clojure struct type?

    - by j-g-faustus
    When defining a struct type and instance, I can print the value and get the "struct" implementation type: (defstruct person :name :age) (def p (struct person "peter" 30)) user=> p {:name "peter", :age 30} user=> (type p) clojure.lang.PersistentStructMap But is it possible to tell whether p is an instance of the struct type "person"?

  • Problem Upgrading NHibernate SQLite Application to .Net 4.0

    - by Xavin
    I have a WPF Application using Fluent NHibernate 1.0 RTM and System.Data.SQLite 1.0.65 that works fine in .Net 3.5. When I try to upgrade it to .Net 4.0 everything compiles but I get a runtime error where the innermost exception is this: `The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found.` The only change made to the project was switching the Target Framework to 4.0.

  • Why is the volatile qualifier used through out std::atomic?

    - by Caspin
    From what I've read from Herb Sutter and others you would think that volatile and concurrent programming were completely orthogonal concepts, at least as far as C/C++ are concerned. However, in GCC c++0x extension all of std::atomic's member functions have the volatile qualifier. The same is true in Anthony Williams's implementation of std::atomic. So what's deal, do my atomic<> variables need be volatile or not?

  • How to setup a webserver in common lisp?

    - by Serpico
    Several months ago, I was inspired by the magnificent book ANSI Common Lisp written by Paul Graham, and the statement that Lisp could be used as a secret weapon in your web development, published by the same author on his blog. Wow, that is amazing. That is something that I have been looking for long time. The author really developed a successful web applcation and sold it to Yahoo. With those encouraging images, I determined to spend some time (1 year or 2 year, who knows) on learning Common Lisp. Maybe someday I will development my web application and turn into a great Lisp expert. In fact, this is the second time for me to get to study Lisp. The first time was a couple of years ago when I was fascinated by the famous book SICP but found later Scheme was so unbelievably immature for real life application. After reading some chapters of ANSI Common Lisp, I was pretty sure that is a great book full of detailed exploration of Common Lisp. Then I began to set up a web server in Common Lisp. After all, this should be the best way if you want to learn something. Demonstrations are always better than definations. As suggested by the book Practical Common Lisp (by the way, this is also a great book), I chose to install AllegroServe on some Common Lisp implementation. Then, from somewhere else, I learned that Hunchentoot seems to be better than AllegroServe. (I don't remember where and whom this word is from. So don't argue with me.) Ironically, you know what, I never could installed the two packages on any Common Lisp implementation. More annoyingly, I even don't know why. The machine always spit up a lot of jargon and lead me into a chaos. I've tried searching the internet and have not found anything. Could anybody who has successfully installed these packages in Linux tell me how you did it? Have you run into any trouble? How did you figured out what is wrong and fixed it? The more detailed, the more helpful.

  • Simple factory to retrieve files using constructor dependency injection

    - by mrblah
    I want to create a class, that is flexible so I can switch implementations. Problem: Store files/documents Options: either store locally on the server filesystem, database or etc. Can someone help with a skeleton structure of the class, and how I would call it? I am not using an IoC, and don't really want to just yet. I just want the flexibility where I would make maybe 1 code change in the factory to call another implementation.

  • P3P - compact policy and legal stuff

    - by Matty F
    Is it legally OK to have only a P3P compact policy (allowing cookies in IE6+)? The P3P XML will also be present with company details and a link to the privacy policy, but nothing more. What are the legal implications of P3P and an incorrect implementation, especially in the UK?

  • Equivalent of libwww-perl in .NET or Java

    - by voidvector
    I have written a crawler in Perl awhile back and it was super simple giving the high-level capability of libwww-perl. It is so straight forward in fact, it can take the raw HTML response of one request, and create the next HTTP request for you from the FORMs on that page (as in it will parse the HTML for you). Does anyone know any library like this on .NET or Java? Selenium is out of question because it requires the browser to be open, which we cannot accommodate in our implementation)

  • A/B testing on App Engine?

    - by Silver Dragon
    What would be the simplest implementation of an A/B testing system running on App engine? I'm especially keen towards performance implications of using Datastore for back-end (with looong query times), and database design.

  • Generating tuples for tuples

    - by Nicola Bonelli
    Say you have a tuple and want to generate a new tuple by applying a metafunction on each type of the first one. What' the most efficient C++ metafuntion to accomplish to this task? Is it also possible to use C++0x variadic template to provide a better implementation?

  • Is it worth using std::tr1 in production?

    - by flashnik
    I'm using MS VC 2008 and for some projects Intel C++ compiler 11.0. Is it worth using tr1 features in production? Will they stay in new standard? For example, now I use stdext::hash_map. TR1 defines std::tr1::unordered_map. But in MS implementation unordered_map is just theirs stdext::hash_map, templatized in another way.

  • Java JList model

    - by Alaa
    How can I make a list model from a JList in order to be able to insert an item into it. I want to use this method: addElement(java.lang.Object item) I found an explanation here, but the problem is that ListModel is an interface and even if I write an implementation and override its method, I can't use the addElement() method

  • Mobile Safari 5mb HTML5 application cache limit?

    - by JFH
    It's becoming evident in my testing that there's a 5mb size limit on Mobile Safari's implementation of HTML5's application cache. Does anyone know how to circumvent or raise this? Is there some unexposed meta tag that I should know about? I have to cache some video content for an offline app and 5mb is not going to be enough.

  • "Hello World" in less than 20 bytes

    - by xelurg
    We have had an interesting competition once, where everyone would write their implementation of hello world program. One requirement was that is should be less than 20 bytes in compiled form. the winner would be the one whose version is the smallest... What would be your solution? :) Platform: 32bit, x86 OS: DOS, Win, GNU/Linux, *BSD Language: Asm, C, or anything else that compiles into binary executable (i.e. no bash scripts and stuff ;)

  • Cocoa - Timer object that can be started, suspended, resumed?

    - by psychotik
    I'm looking for a repeating timer object that allows me to create it once and then suspend and resume it as needed for the lifetime of my application. I've seen documentation for NSTimer and although I think I can make it do what I want by building an abstraction on top of it that creates/invalidates timer objects multiple times, I was curios if there is a better way using some other system timer implementation. I'm not too familiar with Mac development and couldn't find any other leads besides NSTimer.

  • EF Query Object Pattern over Repository Example

    - by Dale Burrell
    I have built a repository which only exposes IEnumerable based mostly on the examples in "Professional ASP.NET Design Patterns" by Scott Millett. However because he mostly uses NHibernate his example of how to implement the Query Object Pattern, or rather how to best translate the query into something useful in EF, is a bit lacking. I am looking for a good example of an implementation of the Query Object Pattern using EF4.

  • How do you keep track of your thought process ?

    - by Johnny Blaze
    I find it very hard to answer question like : "why did you implemented it this way?" or "what's the reason of using that instead of that?" usually because the implementation is the result of a long thought process and trials and errors. By the time i'm finished i can't recall every specific details. I wanted to know if you have some tips to keep track of your thought process and answer those question easily.

  • objective-c default init method for class?

    - by Alex
    Hello, I have two differing methods for initializing my objective-c class. One is the default, and one takes a configuration parameter. Now, I'm pretty green when it comes to objective-c, but I've implemented these methods and I'm wondering if there's a better (more correct/in good style) way to handle initialization than the way I have done it. Meaning, did I write these initialization functions in accordance with standards and good style? It just doesn't feel right to check for the existence of selfPtr and then return based on that. Below are my class header and implementation files. Also, if you spot anything else that is wrong or evil, please let me know. I am a C++/Javascript developer who is learning objective-c as hobby and would appreciate any tips that you could offer. #import <Cocoa/Cocoa.h> // class for raising events and parsing returned directives @interface awesome : NSObject { // silence is golden. Actually properties are golden. Hence this emptiness. } // properties @property (retain) SBJsonParser* parser; @property (retain) NSString* eventDomain; @property (retain) NSString* appid // constructors -(id) init; -(id) initWithAppId:(id) input; // destructor -(void) dealloc; @end #import "awesome.h" #import "JSON.h" @implementation awesome - (id) init { if (self = [super init]) { // if init is called directly, just pass nil to AppId contructor variant id selfPtr = [self initWithAppId:nil]; } if (selfPtr) { return selfPtr; } else { return self; } } - (id) initWithAppId:(id) input { if (self = [super init]) { if (input = nil) { input = [[NSString alloc] initWithString:@"a369x123"]; } [self setAppid:input]; [self setEventDomain:[[NSString alloc] initWithString:@"desktop"]]; } return self; } // property synthesis @synthesize parser; @synthesize appid; @synthesize eventDomain; // destructor - (void) dealloc { self.parser = nil; self.appid = nil; self.eventDomain = nil; [super dealloc]; } @end Thanks!

  • Perl vs Python but with more style than normally

    - by user350571
    I'm learning perl and everytime I search for perl stuff in the internet I get some random page with people saying that perl should die because code written in it looks like a lesson in steganography. Then they say that python is clean and stuff like that. Now, I know that those comparisons are always stupid and made by fellows that feel that languages are a extension of their boring personality so, let me ask instead: can you give me the implementation of a widely known algorithm to deal with a data structure like red-black trees in both languages so I can compare?
