  • httpClient proxy support in apache commons 3.1

    - by user1173339
    I am using apache commons 3.1 to implement httpClient with proxy support. I am trying to connect to a remote host through proxy. The proxy server is configured without any authentication, however the the remote host is configured with authentication. When I am passing the proxy parameters through properties file, it gives warning while execution: WARN - Required proxy credentials not available for BASIC @xx.xx.xx.xx WARN - Preemptive authentication requested but no default proxy credentials availble But the execution goes ahead. On the other hand when I am passing the proxy parameters through the JVM arguments then the again the same warning is given and the execution is stopped. Is there any specific reason for this behavior? Is there any difference in passing the proxy parameters through properties file and through JVM arg? Here is the code: if(System.getProperty("http.proxyHost") != null && System.getProperty("http.proxyPort") != null) { httpClient.getHostConfiguration().setProxy(System.getProperty("http.proxyHost"), Integer.parseInt(System.getProperty("http.proxyPort"))); } else if(AMXAdminTask.props.getProperty("http.proxyHost") != null && AMXAdminTask.props.getProperty("http.proxyPort") != null) { httpClient.getHostConfiguration().setProxy(Propfile.props.getProperty("http.proxyHost"), Integer.parseInt(Propfile.props.getProperty("http.proxyPort"))); }

    - by Zia ur Rahman
    I have just started the Assembly language programming and in the first lecture our teacher told us about intel 8080 and intel 8085 and he said there was 64k memory with these processor. Now i want to know that how we find this amount of memory with specific processor, for example i have a processor 1.8 Ghz , now how i can find out the amount of memory that can be used with this processor. what i am trying to ask is tell me the method how we can find out this amount of memory?

  • Need help in support multiple resolution screen on android

    - by michael
    Hi, In my android application, I would like to support multiple screens. So I have my layout xml files in res/layout (the layout are the same across different screen resolution). And I place my high-resolution asserts in res/drawable-hdpi In my layout xml, I have <?xml version="1.0" encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/table" android:background="@drawable/bkg"> And I have put bkg.png in res/drawable-hdpi And I have started my emulator with WVGA-800 as avd.

  • Help me choose between Go and Io

    - by Robert Smith
    During the following months I'll have some spare time so I thought of picking up a new programming language.I've been reading some articles about Go and Io and both of them look interesting and very promising so I'm stuck making a decision about which one to pick up next. I'm mainly interested in distributed systems and concurrency. Any help is greatly appreciated. Thanks.

  • Stack overflow code golf

    - by Chris Jester-Young
    To commemorate the public launch of Stack Overflow, what's the shortest code to cause a stack overflow? Any language welcome. ETA: Just to be clear on this question, seeing as I'm an occasional Scheme user: tail-call "recursion" is really iteration, and any solution which can be converted to an iterative solution relatively trivially by a decent compiler won't be counted. :-P ETA2: I've now selected a “best answer”; see this post for rationale. Thanks to everyone who contributed! :-)

  • Lightweight development web server with support for PHP v2

    - by David
    In line with this question: http://stackoverflow.com/questions/171655/lightweight-web-app-server-for-php The above question has been asked numerous times and answered exactly the same in all the cases I've found using google. My question is similar to a degree but with a different desired goal: On demand development instances. I have come up with a somewhat questionable solution to host arbitrary directories in my user account for the purpose of development testing. I am not interested in custom vhosts but looking to emulate the behaviour I get when using paster or mongrel for Python & Ruby respectively. Ubuntu 9.10 TOXIC@~/ APACHE_RUN_USER=$USER APACHE_RUN_GROUP=www-data apache2 -d ~/Desktop/ -c "Listen 2990" Is there a better solution, could I do something similar with nginix or lighttpd? Note: The above won't work correctly for stock environments without a copied & altered httpd.conf. Update: The ideal goal is to mimic Paster, Webbrick, and Mongrel for rapid local development hosting. For those light weight servers, it takes less then a minute to get a working instance running ( not factoring any DB support ). Apache2 vhost is great but I've been using Apache2 for over ten years and it would be some sort of abomination hack to setup a new entry in /etc/hosts unless you have your own DNS, in which case a wildcard subdomain setup would probably work great. EXCEPT one more problem, it's pretty easy for me to know what is being hosted ( ex. by paster or mongeral ) just doing a sudo netstat -tulpn while there would be a good possibility of confusion in figure out which vhost is what.

  • Why are there so many Database Management Systems?

    - by mr.bio
    Why are there so many Database management systems? I am not an DB expert and I've never thought about using another Database other than mySQL. Programming languages offer different paradigms, so it makes sense to choose a specific language for your purpose. Question What are the factors in choosing a specific Database management system ?

  • Compiling x264 with mp4 support problem

    - by johnas
    I'm trying to compile x264 with mp4 output support. I download the latest version from their git by typing git clone git://git.videolan.org/x264.git When I run ./configure it configures and I'm able to make it. But when i try to configure it with ./configure --enable-mp4-output and then try to make it, it returns a strange error, indicating that there is a compilation error. The error message looks like: ... Lots of similar errors ... output/mp4.c:297: warning: implicit declaration of function ‘gf_isom_add_sample’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘p_file’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘i_track’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘i_descidx’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘p_sample’ output/mp4.c:299: error: ‘mp4_hnd_t’ has no member named ‘p_sample’ output/mp4.c:300: error: ‘mp4_hnd_t’ has no member named ‘i_numframe’ I've tried different releases. I've installed gpac, ffmpeg, and tried numerous tips from the net. But still can't get it to work. The reason I want it with mp4 output is because I want to use ffmpeg to create mp4 files encoded with x264. I'm running Ubuntu Server 9.10 32 bits.

  • Multiple Application Support Directories for iPhone Simulator?

    - by Alex G
    I am developing an iPhone app with someone else. The app works fine for me, but he is running into a bug. We think this bug is related to the fact that he is getting multiple Application directories for this same app. In my ~/Library/Application Support/iPhone Simulator/User/Applications, I only have one folder at all times. He says that he will get 3 or 4 directories when he is only working on this one app. We think this is our problem because our bug has to do with displaying images that are stored in the app's Documents folder. Does anyone know why he is ending up with multiple directories or how to stop it? Edit: Here is the code for writing the image to a file: NSData *image = [NSData dataWithContentsOfURL:[NSURL URLWithString:[currentArticle articleImage]]]; NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *imagePath = [array objectAtIndex:0]; NSFileManager *NSFM = [NSFileManager defaultManager]; BOOL isDir = YES; if(![NSFM fileExistsAtPath:imagePath isDirectory:&isDir]) if(![NSFM createDirectoryAtPath:imagePath attributes:nil]) NSLog(@"error"); imagePath = [imagePath stringByAppendingFormat:@"/images"]; if(![NSFM fileExistsAtPath:imagePath isDirectory:&isDir]) if(![NSFM createDirectoryAtPath:imagePath attributes:nil]) NSLog(@"error"); imagePath = [imagePath stringByAppendingFormat:@"/%@.jpg", [currentArticle uniqueID]]; [image writeToFile:imagePath atomically:NO]; And here is the code for getting the path when I need the image: - (NSString *)imagePath { NSArray *array = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *imagePath = [array objectAtIndex:0]; return [imagePath stringByAppendingFormat:@"/images/%@.jpg", [self uniqueID]]; } The app works great for me, but my partner says that the images don't show up intermittently, and he notices that he gets multiple directories in his Applications folder.

  • Does NHibernate LINQ support ToLower() in Where() clauses?

    - by Daniel T.
    I have an entity and its mapping: public class Test { public virtual int Id { get; set; } public virtual string Name { get; set; } public virtual string Description { get; set; } } public class TestMap : EntityMap<Test> { public TestMap() { Id(x => x.Id); Map(x => x.Name); Map(x => x.Description); } } I'm trying to run a query on it (to grab it out of the database): var keyword = "test" // this is coming in from the user keyword = keyword.ToLower(); // convert it to all lower-case var results = session.Linq<Test> .Where(x => x.Name.ToLower().Contains(keyword)); results.Count(); // execute the query However, whenever I run this query, I get the following exception: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index Am I right when I say that, currently, Linq to NHibernate does not support ToLower()? And if so, is there an alternative that allows me to search for a string in the middle of another string that Linq to NHibernate is compatible with? For example, if the user searches for kap, I need it to match Kapiolani, Makapuu, and Lapkap.

  • Reading Source Code Aloud

    - by Jon Purdy
    After seeing this question, I got to thinking about the various challenges that blind programmers face, and how some of them are applicable even to sighted programmers. Particularly, the problem of reading source code aloud gives me pause. I have been programming for most of my life, and I frequently tutor fellow students in programming, most often in C++ or Java. It is uniquely aggravating to try to verbally convey the essential syntax of a C++ expression. The speaker must give either an idiomatic translation into English, or a full specification of the code in verbal longhand, using explicit yet slow terms such as "opening parenthesis", "bitwise and", et cetera. Neither of these solutions is optimal. On the one hand, an idiomatic translation is only useful to a programmer who can de-translate back into the relevant programming code—which is not usually the case when tutoring a student. In turn, education (or simply getting someone up to speed on a project) is the most common situation in which source is read aloud, and there is a very small margin for error. On the other hand, a literal specification is aggravatingly slow. It takes far far longer to say "pound, include, left angle bracket, iostream, right angle bracket, newline" than it does to simply type #include <iostream>. Indeed, most experienced C++ programmers would read this merely as "include iostream", but again, inexperienced programmers abound and literal specifications are sometimes necessary. So I've had an idea for a potential solution to this problem. In C++, there is a finite set of keywords—63—and operators—54, discounting named operators and treating compound assignment operators and prefix versus postfix auto-increment and decrement as distinct. There are just a few types of literal, a similar number of grouping symbols, and the semicolon. Unless I'm utterly mistaken, that's about it. So would it not then be feasible to simply ascribe a concise, unique pronunciation to each of these distinct concepts (including one for whitespace, where it is required) and go from there? Programming languages are far more regular than natural languages, so the pronunciation could be standardised. Speakers of any language would be able to verbally convey C++ code, and due to the regularity and fixity of the language, speech-to-text software could be optimised to accept C++ speech with a high degree of accuracy. So my question is twofold: first, is my solution feasible; and second, does anyone else have other potential solutions? I intend to take suggestions from here and use them to produce a formal paper with an example implementation of my solution.

  • Does Team Foundation support cross-app workitem groups?

    - by drachenstern
    We're currently using Visual Source Safe and BugNet and looking to migrate up and away from VSS. I've been pushing for either SVN ( a) we're an ASP.NET shop, b) DCVS is not an option - no matter how much I like Hg ;-) or TFS. Well we finally got a new dev server, so I talked the boss into installing TFS on it (30 day trial). In the meantime, we had started experimenting with FogBugz. We really like FogBugz for about 80% of what we want to do, and the other 20% is probably stuff that we don't know what we want. I'm pushing for TFS because it allows for IDE integrated (mostly) everything. He's pushing for FogBugz because he can group tasks by customer and then project and manage everything from one dashboard. (which means I lose most of my IDE integration - no huge loss I agree) Does TFS support a single dashboard that would span all our solutions (in this case each solution is a full app that we sell to a vertical market client) and let us assign workitems to each solution-spanning-group? So for instance I think we envision something like this: PROJECT1 - Bugtracker and workitems PROJECT2 - Bugtracker and workitems PROJECT3 - Bugtracker and workitems CUSTOMER1 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT2) CUSTOMER2 - Deployment schedules, required features, specific notes (Uses PROJECT2, PROJECT3) CUSTOMER3 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT3) Hopefully that makes sense. naturally it's more complicated than this but I think I've given the details enough to paint a picture. I offered the option of creating dummy projects per customer but he doesn't like that and it doesn't really give us the single dashboard view that we're hoping to end up with (and that FogBugz as we've sorta implmented things does do now). Has anyone got a good suggestion on a management app that would accomplish what both of us want?

  • Are there any strongly typed scripting languages?

    - by George Edison
    I am wondering if there are any strongly typed scripting languages. Python, JavaScript, etc. are great languages, but they are (to a certain degree) loosely typed. I am just wondering if anyone knows of any strongly typed scripting languages. And by scripting, I mean a language whose interpreter can be embedded in a C++ application.

  • Object doesn't support property or method 'transformNode' in Internet Explorer 10 (Windows 8)

    - by John Chapman
    I am having some JavaScript issues that seem to only occur in Internet Explorer 10 on Windows 8 (IE 7, 8, and 9 all work fine). The basic jist of what I am doing is getting XML and XSL from a web service and then transforming them in JavaScript to render on the page using the Sys.Net.XMLDOM object. XMLDOM = Sys.Net.XMLDOM; var xsl = // XSL gotten from somewhere else var xmlString = // XML gotten from somewhere else as a string... var xml = new XMLDOM(xmlString); var content = xml.transformNode(xsl); When I use the above code in IE 10, I get: Object doesn't support property or method 'transformNode' Any ideas on why Internet Explorer 10 is doing this? EDIT I have also tried this: xmldoc = new ActiveXObject("Msxml2.DOMDocument"); xmldoc.async = false; xmldoc.load(xml); xsldoc = new ActiveXObject("Msxml2.DOMDocument"); xsldoc.async = false; xsldoc.load(xsl); var content = xmldoc.transformNode(xsldoc); Which works in all previous versions of IE, but in IE 10 I get: Reference to undeclared namespace prefix: 'atom'.

  • Generating video or images of geometrical objects from data

    - by Jonathan Barbero
    Hello, I'm working in a course's project to predict the velocity and position of the solar system planets (and other objects). It will be really cool if I can visualize the predicted objects data, if it's possible generating 3D images, if in video that's amazing. Do you know any library that lets me to use this data to generate an image or video? (I don't care in which language) Data: - simulation step (time line step for a video) - positions of the objects - radius and/or colours of the objects Thanks in advance, any suggestion is welcome.

  • Role of Combinators in Concatenative/Tacit Programming Languages.

    - by Bubba88
    Hi! I have a question about what exact role do higher-order compinators (or function producers) hold in concatenative/tacit programming. Additionally I would like to ask if there is another way to implement concatenative programming language rather than directly manipulating the stack. This might look like a newbie question, so if you feel like it, you can freely direct me to external source.

  • Have you ever crashed the compiler?

    - by Motti
    Everyone (at least everyone who uses a compiled language) has faced compilation errors but how many times do you get to actually crash the compiler? I've had my fair share of "internal compiler errors" but most went away just by re-compiling. Do you have a (minimal) piece of code that crashes the compiler?
