  • OpenMP timer doesn't work on inline assembly code?

    - by Brett
    I'm trying to compare some code samples for speed, and I decided to use the OpenMP timer since I'll eventually be multi threading the code. The timer works great on two of my four code snippets, but not on the other two start=omp_get_wtime(); /*code here*/ finish = omp_get_wtime() - start_time; The four code here sections are serial code, xmmintrin.h code, and two inline assembly codes. The serial and xmminstrin.h code are able to be timed, but the inline assembly codes returns -1.#IND00 for a time. I can't seem to figure out why this is? Thanks for any help or suggestions!

  • What is the right license for tutorial source code ?

    - by devdude
    Putting sourcecode from tutorials or books online requires the author to add some kind of disclaimer or license (otherwise people would use it make lots of $$$ or break a power plant IT control system and sue you as author). But what is the right license or disclaimer statement ? Can I use BSD license with ... IN NO EVENT SHALL THE COPYRIGHT HOLDER OR CONTRIBUTORS BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING, BUT NOT LIMITED TO, PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES; LOSS OF USE, DATA,... We are talking about tutorials ! Released to teach and share knowledge. Or do I need to follow the (potentially different) licenses of the libraries I use ? Might be insignificant now but I feel we will face a license hunt in "public" sourcecode (aka OSS) in future, similar to companies/lawyers currently crawling the web for pictures with wrong copyright statement or infringing their IP (and suing someone using a picture in a personal blog,etc..).

  • I/O between AIR client using Native process and executable java .jar

    - by aseem behl
    I am using Adobe AIR 2.0 native process API to launch a java executable jar. I/O is handled by writing to the input stream of the java process and reading from the output stream. The application is event based where several events are fired from the server. We catch these events in java code, handle them and write the output to the outputstream using the synchronized static method below. public class ReaderWriter { static Logger logger = Logger.getLogger(ReaderWriter.class); public synchronized static void writeToAir(String output){ try{ byte[] byteArray = output.getBytes(); DataOutputStream dataOutputStream = new DataOutputStream(System.out); dataOutputStream.write(byteArray); dataOutputStream.flush(); } catch (IOException e) { logger.info("Exception while writing the output. " + e); } } } The issue is that some messages are lost between the transfer and not all messages reach the AIR client. If I run the java application from the console I am receiving all the messages. It would be great if somebody could point out what I am missing. Following are some of the listeners used to send the event data to the AIR client. // class used to process Shutdown events from the Session private class SessionShutdownListener implements SessionListener{ public void onEvent(Event e) { Session.Shutdown sd = (Session.Shutdown) e; Session.ShutdownReason sr = sd.getReason(); String eventOutput = "eo;" + "Session Shutdown event ocurred reason=" + sr.strValue() + "\n"; ReaderWriter.writeToAir(eventOutput); } } // class used to process OperationSucceeded events from the Session private class SessionOperationSucceededListener implements SessionListener{ public void onEvent(Event e) { Session.OperationSucceeded os = (Session.OperationSucceeded) e; String eventOutput = "eo;" + "Session OperationSucceeded event ocurred" + "\n"; ReaderWriter.writeToAir(eventOutput); } }

  • Help with SOAP request using PHP

    - by mptre
    I'm having a SOAP related problem in PHP. I'm trying to create arbitrary SOAP request using Nusoap_client class. The complete request including headers should look like the example below. Ofcourse the placeholders (string) should be replaced with actual values. POST /services/RecipeCouponAPI11.asmx HTTP/1.1 Host: example.com Content-Type: text/xml; charset=utf-8 Content-Length: length SOAPAction: "http://www.example.com/services/GetCouponAll" <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Header> <RCAuthenticator xmlns="http://www.example.com/services/"> <UserName>string</UserName> <Password>string</Password> </RCAuthenticator> </soap:Header> <soap:Body> <GetCouponAll xmlns="http://www.example.com/services/"> <campaignCode>string</campaignCode> </GetCouponAll> </soap:Body> </soap:Envelope> I tried the following code with no luck. Seems like the request isn't formated correctly. Any ideas on how to get his working? <?php $client = new Nusoap_client('http://www.example.com/services/RecipeCouponAPI11.asmx'); $headers = new SoapHeader( 'http://www.example.com/services/', 'RCAuthenticator', (object)array( 'UserName' => 'username', 'Password' => 'password' ), false ); $client->setHeaders(array($headers)); $response = $client->call( 'GetCouponAll', array('campaignCode' => 'campaigncode'), null, 'http://www.example.com/services/GetCouponAll' ); ?> Thanks in advantage!

  • Strange behavior of I() in left-/right-hand side of formula

    - by adibender
    set.seed(98234) y <- rnorm(100) x <- rnorm(100) lm0 <- lm(y ~ x) lm1 <- lm(I(y) ~ I(x)) all work perfectly fine and I guess we can agree that ´lm0´ is what one would expect to happen. lm1 is equal to lm0 (judging by coefficients). So are set.seed(98234) lm3 <- lm(I(rnorm(100)) ~ rnorm(100)) set.seed(98234) lm4 <- lm(rnorm(100) ~ I(rnorm(100))) But when I() is on neither or both sides of the formula I don't get the results from above: set.seed(98234) lm2 <- lm(I(rnorm(100)) ~ I(rnorm(100))) set.seed(98234) lm5 <- lm(rnorm(100) ~ rnorm(100)) Any ideas why?

  • DDD: Client-side script to enforce invariants

    - by Mosh
    Hello, One thing that I'm confused about in regards to DDD is that our domain is supposed to handle all business logic and enforce invariants. I have noticed some people (me included) handle certain invariants in the presentation layer (i.e. WebForms, Views, etc) with javascript. This is mainly done to improve performance so the server is not hit for every request which may be invalid. Even though this approach may be beneficial performance-wise, it violates DDD principles. What if the business rules are changed? This way we don't have a rich domain where all the business rules are captured. In case of a change, we should change the domain as well as the presentation layer. Has anyone come across this situation before? I'd like to know your thoughts on this. Cheers, Mosh

  • how to verify browser IP for server-side web service

    - by Anthony
    I have a web service that needs to be able to verify the end-user's IP that called the server-script that is requesting the web service. Simple layout: Person A goes to Webpage B. Webpage B calls Web Service C to get some info on Person A. Web Service C won't give Webpage B the requested information without confirmation that the request originated from Person A's IP and not someone who has stolen Person A's session. I'm thinking that for a browser-based solution, the original site (Webpage B) can open an iframe that goes to the Web Service's authentication page. A key of some kind is passed to the browser which will some how indicate both the user's IP and Web Page B's IP, so that the Web Service can confirm that no one has nabbed anything. I have two challenges, but I'll stick to the more immediate one first: I'm not sure if my browser-based plan really makes sense. If someone steals the session cookie, how is the Web Service going to know? Would this cookie be held be Web Page B and thus be harder to steal? Is it a sound assumption that a cookie or key held by the server only and not the browser is safe? Also, would the web service, based on the iframe initial connection, be expecting the server/user-ip combo? What I mean is, does the session key provided via the iframe get stored by the web service and the Web Site B shows it has a match? Or is the session key more generic, meaning the web service is passed the key by Website B and the Web Service verifies that this is a valid session key based on what a valid session key should look like?

  • Real time web services

    - by daliz
    Hi everybody, I have a little (maybe the answer could require a book) question about web services and server side programming. But first, a little preamble. Recently we have seen new kind of applications & games using some kind of real-time interaction with a database, or more generally, with other users. I'm talking about shared drawing canvas, games like this , or simple chats, or the Android app "a World of Photo", where in real time you see who is online, to share your photos, etc. Now my question: Are all these apps based on classic TCP client/server architectures or is there a way to make them in a simpler way, like a web platform like LAMP? What I'm asking, in other words is: Can PHP+MySQL (or JSP, or RoR, or any other server language) provide a way to make online users communicate in real time and share data? Is there a way to do that without the ugly and heavy mechanism of temporary tables? Thank you! I hope I've been clear.

  • JQUERY clickout side element

    - by Val
    I have multiple menues on my page... <div class="menu"> <div>Menu header</div> <div>Menu content</div>// should hide on click outside .menu </div> <div class="menu"> <div>Menu header</div> <div>Menu content</div>// should hide on click outside .menu </div> basically i need all the menu(s) to hide when a click is detected unless someone is clicking any of the menues it should hide any other menu(s) apart from the menu they clicked on. I have seen a few that work but only if you have one menu on the page which is not exactly useful using stopPropagation as it may cancel any other necessary instructions; any ideas would be appriciated.

  • CSS - 2 divs side-by-side, one floated - how do I make the other fit next to it without overlapping?

    - by Artem Russakovskii
    I have had the following problem for a while and I am really not sure how to solve it. The problem can currently be observed here: http://www.androidpolice.com/2009/11/16/the-not-so-good-the-bad-and-the-ugly-my-list-of-20-problems-with-htc-hero/ - feel free to use this for Firebugging. There are 2 notions here: a table of contents (toc) and notes. A note usually takes 100% of the post width and everything is fine. However, when a note appears next to a toc, the toc starts overlapping and covering the note (I set z-index:1 on the toc because otherwise the note covered it, which was even worse). It's interesting to point out that the text of the note doesn't get covered by the toc - only the note div itself does. In IE7, it's even worse - the note div jumps down to under the toc and leaves a lot of empty space (2nd screenshot). So, how can I solve this? The ideal solution would have the note div occupy 100% of the visible space - i.e. it would resize itself to fit right next to the toc when needed. Any points appreciated. Thank you! Here are some screenshots for future reference: in IE7:

  • remote debug unmanaged code

    - by sagie
    Hi. I have a process that contains C# code, C++\CLI code and native c++ code. Now, I'm trying to remote debug my process, and I can go to the statements of my C# code and my C++\CLI code, but I can't reach my native code. When I try to hit a breakpoint in my native c++ source file, I get the "No symbole have been loaded" error. I tried to manualy load the symboles (tools-options-debugging), but no luck. Any Idea?

  • Are there commercially deployed and used .NET CAS (Code Access Security) based applications?

    - by Dinis Cruz
    I've seen a couple threads here on SO that ask about what CAS is and how to use it.My specific is specifically focused on real-world usages of CAS. For example: DotNetNuke did some efforts in the past to be able to run under Medium Trust: is that still true? what is the % of DNN that run in partial trust (i.e. not full trust)? what & of DNN modules run in partial trust?) Sharepoint defaults to a Partially-Trusted environment on dlls executed from the bin folder: How many 'commercially' available WebParts can run in this bin folder (without changing the policy)? The key here is to be able to point to CAS success stories, so that other companies feel that they should also invest in writing CAS-enabled apps

  • Need PHP Email Script Solution

    - by JCHASE11
    Designing forms has always been fun, but getting them to send email on the server side is another story. I have used various email scripts (dynaform,phpmailer, etc), and have experienced a ton of problems. So here is the site I am working on: Contact On the Right. It is very basic: no validation, no required fields. I simply need anything that is entered to be sent back to me. Does anyone know of any BASIC PHP form processing scripts, or have a few lines of code that would work here? I'm not a PHP guy, so I am struggling! Thanks in advance.

  • How can I trigger a server-side event from a client-side event?

    - by danish
    Short version All I need is that, in a ModalPopUp, when the DoubleClick event of a ListItem fires, the click event of my OK button should be executed. Detail I have a ModalPopUpExtender, which hosts a user control. The user control has an OK and a Cancel button. Along with that, it has a dynamic ListBox added to it. So far, I've considered the following possible solutions: Use Ajax.Net. But, I cannot afford to have a WebMethod. Use a ClientScriptCallBack. This will need a lot of JavaScript, since I have made almost every control dynamic. Is there any other way apart from using an UpdatePanel?

  • JPA @ManyToMany on only one side?

    - by Ethan Leroy
    I am trying to refresh the @ManyToMany relation but it gets cleared instead... My Project class looks like this: @Entity public class Project { ... @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER) @JoinTable(name = "PROJECT_USER", joinColumns = @JoinColumn(name = "PROJECT_ID", referencedColumnName = "ID"), inverseJoinColumns = @JoinColumn(name = "USER_ID", referencedColumnName = "ID")) private Collection<User> users; ... } But I don't have - and I don't want - the collection of Projects in the User entity. When I look at the generated database tables, they look good. They contain all columns and constraints (primary/foreign keys). But when I persist a Project that has a list of Users (and the users are still in the database), the mapping table doesn't get updated gets updated but when I refresh the project afterwards, the list of Users is cleared. For better understanding: Project project = ...; // new project with users that are available in the db System.out.println(project getUsers().size()); // prints 5 em.persist(project); System.out.println(project getUsers().size()); // prints 5 em.refresh(project); System.out.println(project getUsers().size()); // prints 0 So, how can I refresh the relation between User and Project?

  • How to send complex types from PHP SoapClient to ASP.NET SOAP server?

    - by xaguilars
    Hello I'm having problems sending arrays, structs and arrays of structs from PHP to an ASP.NET SOAP server... Anyone have a sollution for this? I've googled for days and any sollution worked for me. Perphaps I'm forgetting something... There are examples of my code: $client = new SoapClient($options); $pCriteria = new stdClass(); $pCriteria->type=1; $pCriteria->capacity=4; //Test 1 (fail): $resp = $client->GetRooms(array("pCriteria"=>$pCriteria)); //Test 2 (fail): $resp = $client->GetRooms(array("pCriteria"=>new SoapVar($pCriteria, SOAP_ENC_OBJECT, "TCriteria", "http://www.w3.org/2001/XMLSchema"))); print_r($resp); I don't know how to code functions that require an array of TCriteria (TCriteria[], TCriteria_Array type) either... i've tried sending the raw array, a SoapVar with SOAP_ENC_ARRAY encoding and TCriteria_Array type, ... but it does not work (the SOAP server becomes unavaiable and needs to be restarted). I've tried creating classes for the complex types too, instead of stdClass, but not working. I don't know where's the problem. The server admins cannot help me and I haven't found any sollution over internet. I'm a bit desperate hehe. Can you help me please? Can you provide samples of code with the three cases (array of simple data, array of struct and struct) ? Thanks!
