  • How to test reliability of my own (small) embedded operating system ?

    - by TridenT
    I've written a small operating system for embedded project running on small to medium target. I added some automated unit test with a high test code coverage (95%), but the scope is only the static part. I got some code metrics as complexity and readability. I'm testing my code with a rule checker with MiSRA support, and of course fixed all warnings. I'm testing the code with a static analyzer and again fixed all warnings. What can I do now to test - and improve - the reliability of my OS ? How about the dynamic part ?

  • How do I produce a screenshot of a flash swf on the server?

    - by indignant
    I'm writing a flash app using the open source tools. I would like to load a data file in to the app and capture a screenshot of the stage on the server. The only part that seems mysterious is running the app on the server. In fact, I don't even care if it's the same app running on the server and in the browser--if I can use the flash stage and drawing routines to produce an image server-side, I'm happy. If I have to delve in to flex, fine. Right now I'm having problems finding any starting point at all. I gather Adobe has some commercial products that may fit the bill, but I'd like to stick with open source, apache, and linux. I know this is probably possible with haxe/neko, but I'd like to use more mainstream tools if possible. Am I asking too much? EDIT/CLARIFICATION: Many thanks for the responses so far, but I think I've been a bit muddy in my description. I've already written the actual stage-grabbing stuff using the same PNGEncoder class as was suggested. The problem is in actually running the swf on the server side. I don't want to let the client take the screen shot itself, because this opens up the possibility of the client maliciously submitting a screenshot which does not correspond to what is on the stage, that is, I don't want users uploading porn. If I could run the the actionscript code on the server, then I could generate the screenshot from my data files and be sure that the screenshot matches the data, but I have no idea how to run the actionscript or swf on the server.

  • Using ms: xpath functions inside XPathExpression

    - by Filini
    I am trying to use Microsoft XPath Extension Functions (such as ms:string-compare http://msdn.microsoft.com/en-us/library/ms256114.aspx) inside an XPathExpression object. These functions are extensions inside the MSXML library, and if I use them in an XslCompiledTransform (simply adding the "ms" namespace) they work like a charm: var xsl = @" <?xml version=""1.0"" encoding=""UTF-8""?> <xsl:stylesheet version=""2.0"" xmlns:xsl=""http://www.w3.org/1999/XSL/Transform"" xmlns:xs=""http://www.w3.org/2001/XMLSchema"" xmlns:fn=""http://www.w3.org/2005/xpath-functions"" xmlns:ms=""urn:schemas-microsoft-com:xslt""> <xsl:output method=""xml"" version=""1.0"" encoding=""UTF-8"" indent=""yes""/> <xsl:template match=""/Data""> <xsl:element name=""Result""> <xsl:value-of select=""ms:string-compare(@timeout1, @timeout2)""/> </xsl:element> </xsl:template> </xsl:stylesheet>"; var xslDocument = new XmlDocument(); xslDocument.LoadXml(xsl); var transform = new XslCompiledTransform(); transform.Load(xslDocument); Then I tried using them in an XPathExpression: XPathNavigator nav = document.DocumentElement.CreateNavigator(); XPathExpression expr = nav.Compile("ms:string-compare(/Data/@timeout1, /Data/@timeout2)"); XmlNamespaceManager manager = new XmlNamespaceManager(document.NameTable); manager.AddNamespace("ms", "urn:schemas-microsoft-com:xslt"); expr.SetContext(manager); nav.Evaluate(expr); But I get an exception "XsltContext is needed for this query because of an unknown function". XsltContext is a specific XmlNamespaceManager, but I don't know if it's possible to instantiate it without an actual XslCompiledTransform (it's abstract) and use it as my expression context. Is there any way to do this (or any other way to use ms: extensions inside an XPathExpression)?

  • Problem using the prependTo() in jQuery

    - by raulriera
    Hi all, I am having a problem trying to use the prependTo() function in jQuery... for some reason I can't get this to work $(" <div id="note178" class="note"> <div class="delete"><a href="/chart-notes/delete/178" onclick="$.ajax({ dataType: 'script', url: '/chart-notes/delete/178'}); return false;"><img src='/images/icons/delete.png'></a></div> <div class="timestamp">1 minute ago </div> <div class="content">ñasdas dasdasdasd conclusión</div> </div> ").prependTo(".notes").fadeIn("slow"); Although when doing it like this, it works fine $.ajax({ url:'/chart-notes/show/<cfoutput>#chartnote.id#</cfoutput>', success: function(data) { $(data).prependTo(".notes").fadeIn("slow"); // Scroll to the top of the annotations $('html, body').animate({scrollTop: $(".notes").offset().top}, 1000); // Clear the form $('#chartnote-notes').val(""); } }); The "data" response from that success function is the same <div id="note178" class="note"> <div class="delete"><a href="/chart-notes/delete/178" onclick="$.ajax({ dataType: 'script', url: '/chart-notes/delete/178'}); return false;"><img src='/images/icons/delete.png'></a></div> <div class="timestamp">1 minute ago </div> <div class="content">ñasdas dasdasdasd conclusión</div> </div> As before

  • What can I do to get Mozilla Firefox to preload the eventual image result?

    - by Dalal
    I am attempting to preload images using JavaScript. I have declared an array as follows with image links from different places: var imageArray = new Array(); imageArray[0] = new Image(); imageArray[1] = new Image(); imageArray[2] = new Image(); imageArray[3] = new Image(); imageArray[0].src = "http://www.bollywoodhott.com/wp-content/uploads/2008/12/arjun-rampal.jpg"; imageArray[1].src = "http://labelleetleblog.files.wordpress.com/2009/06/josie-maran.jpg"; imageArray[2].src = "http://1.bp.blogspot.com/_22EXDJCJp3s/SxbIcZHTHTI/AAAAAAAAIXc/fkaDiOKjd-I/s400/black-male-model.jpg"; imageArray[3].src = "http://www.iill.net/wp-content/uploads/images/hot-chick.jpg"; The image fade and transformation effects that I am doing using this array work properly for the first 3 images, but for the last one, imageArray[3], the actual image data of the image does not get preloaded and it completely ruins the effect, since the actual image data loads AFTERWARDS, only at the time it needs to be displayed, it seems. This happens because the last link http://www.iill.net/wp-content/uploads/images/hot-chick.jpg is not a direct link to the image. If you go to that link, your browser will redirect you to the ACTUAL location. Now, my image preloading code in Chrome works perfectly well, and the effects look great. Because it seems that Chrome preloads the actual data - the EVENTUAL image that is to be shown. This means that in Chrome if I preloaded an image that will redirect to 'stop stealing my bandwidth', then the image that gets preloaded is 'stop stealing my bandwidth'. How can I modify my code to get Firefox to behave the same way?

  • algorithm to find Best 8 minute window in a 1 hour run

    - by Arun
    I have a requirement like, an activity runs for about more than an hour. I need to get the best 8 minute window where some parameters are maximum. say a value x, which is dynamic for every second. if my activity runs for one hr,i get 3600 values for x. I need to find the best continuous 8 minute time interval where x value was the highest among all the others. if i capture say from 0th minute to 8th minute, there may be another time frame like 0.4 to 8.4 where it was maximum. the granularity is one second. every second we need to consider. basically the peak 8 minute window where x was maximum. please help me with the design

    - by matti
    THE PROBLEM IS SOLVED. I DUNNO HOW TO CLOSE THIS QUESTION. ANOTHER SERVICE IS PROPABLY RUNNING AT ALMOST SAME SYNC THAT DOES THE THING. MY WORK "MATE" WILL HEAR A THING OR TWO IN THE MORNING. I have following code in windows service: data is in the dataset and it has been populated earlier and then rows are updated and inserted to dataset tables before calling code below. using (dataSetTxn = _cnctn.BeginTransaction()) { try { _somePlanAdptr.UpdateCommand.Transaction = dataSetTxn; _someLogAdptr.InsertCommand.Transaction = dataSetTxn; _someLinkAdptr.InsertCommand.Transaction = dataSetTxn; _someDataAdptr.InsertCommand.Transaction = dataSetTxn; _log.WriteDebug("Updating SomePlanAction"); _somePlanAdptr.Update(_ofDataSet, "SomePlanAction"); _log.WriteDebug(string.Format("Inserting {0} rows to SomeLog")); //error _someLogAdptr.Update(_ofDataSet, "SomeLog"); _log.WriteDebug(string.Format("Updating SomeLink with {0} rows", _ofDataSet.Tables["SomeLink"].Rows.Count)); _someLinkAdptr.Update(_ofDataSet, "SomeLink"); _log.WriteDebug(string.Format("Updating SomeData with {0} rows", _ofDataSet.Tables["SomeData"].Rows.Count)); _someDataAdptr.Update(_ofDataSet, "SomeData"); _log.WriteDebug("Commiting all changes to database."); dataSetTxn.Commit(); } catch (Exception e) { _log.WriteError("Updating database failed -> rollback", e); if (dataSetTxn != null && _cnctn.State == ConnectionState.Open) dataSetTxn.Rollback(); throw e; } } so one of the lines causes an exception log.WriteDebug(string.Format("Inserting {0} rows to SomeLog")); //error still the first adapter's data is updated to database. when debugged the data is not yet updated until the method that calls all (including this bit) exits.

  • .Net in HTML tp return true if reader object not null, otherwise return false

    - by Phill Healey
    I'm using a DataList to show some data from the database and populating the fields on the html side. I now have a requirement to change the visibility of a panel based on whether or not a db field has data or not. I need to be able to show the panel if the relevant data field has content, and hide it if it doesn't. Eg: <asp:Panel ID="pnlNew" runat="server" Style="margin:0; padding:0; width:42px; height:18px; bottom:5px; right:10px; float:right; position:relative; background:url(../_imgVideoBadge.png) no-repeat;" Visible='<%# Eval("cheese") != null %>' ToolTip="available"></asp:Panel> Obviously this doesn't work in terms of the visible property. But hopefully it gives an idea of what I'm trying to achieve. Any help would be greatly appreciated. I've seen examples previously of doing something along the lines of: a ?? b:c How could this be applied to the above requirement?? Thanks in advance.

  • Managing Many to Many relationships in asp.net Wizard Control

    - by Luis
    Say I have this entity with a lot of attributes. In the input form I have decided to implement a wizard control so I can collect information about this entity in several steps. The problem is that I need to collect information that has been modeled has many to many relationships. I am planning to use a telerik gridview to manage this (add/edit/delete), the problem is where do I store that data since the entity in a insert form is not created on the database yet. OK so I can store all that info in temporary lists residing in the viewstate, waiting for the final submit where I dump all that in the DB, but one of the steps I am collecting files...now storing files in the viewstate is out of the question, same as as storing them in the session... I have been thinking of implementing in a way that the user has to submit some info first (say first 3 steps), commit the data to the database creating the parent entity and then start inserting all the childs entities...but this will get weird as it's confusing since on the first steps you not saving the data to the DB and on the next ones you are commiting directly... Anyone has any thoughts on this? Thanks

    I have a huge (4,5 GB) csv file.. I need to perform basic cut and paste, replace operations for some columns.. the data is pretty well organized.. the only problem is I cannot play with it with Excel because of the size (2000 rows, 550000 columns). here is some part of the data: ID,Affection,Sex,DRB1_1,DRB1_2,SENum,SEStatus,AntiCCP,RFUW,rs3094315,rs12562034,rs3934834,rs9442372,rs3737728 D0024949,0,F,0101,0401,SS,yes,?,?,A_A,A_A,G_G,G_G D0024302,0,F,0101,7,SN,yes,?,?,A_A,G_G,A_G,?_?

  • More memory usage for IIS 6 asp.net 2.0 on webserver 2003

    - by Alan King
    Running a webserver 2003 SP2 (x86) with IIS 6 and asp.net 2. The box is running mostly dynamic asp pages connecting to a sql 2008 server. At any given time there is over 1 gig of memory available out of the 2 gig in the box. It seems like there would be a way for it to make better use of the free memory. It is using a default machine.config file and default http.sys. I would like to maximize incoming internet connections and database connections. Is there something I can do to make better use of the available memory?

  • Partioning with Hibernate

    - by Alex
    Hello, We have a requirement to delete data in the range of 200K from database everyday. Our application is Java/JEE based using Oracle DB and Hibernate ORM tool. We explored various options like Hibernate batch processing Stored procedure Database partitioning Our DBA suggests database partitioning is the best way to go, so we can easily recreate and drop the partitioned table everyday. Now the issue is we have 2 kinds of data, one which we want to delete everyday and the other which we want to keep it. Suppose this data is stored in table "Trade". Now with partitioning, we have 2 tables "Trade". We have already existing Hibernate based DAO layer to fetch/store trades from/to DB. When we decide to partition the database, how can we control the trades to go in which of the two tables through hibernate. Basically I want , the trades need to be deleted by end of the day, to go in partitioned table and the trades I want to keep, in main table. Please suggest how can this be possible with Hibernate. We may add an additional column to identify the trades to be deleted but how can we ensure these trades should go to partitioned trade table using hibernate. I would appreciate if someone can suggest any better approach in case we are on wrong path.

  • How to save XML file before update?

    - by Robert Iagar
    Right so I have a simple app that consists of a calendar a Set Event button and list box that populates using a DataTemplate in WPF. When I build the app the Events.xml file is like this: <?xml version="1.0" encoding="utf-8" ?> <events> </events> I add events to xml through code. Final structure of the xml file is the following <?xml version="1.0" encoding="utf-8" ?> <events> <event Name="Some Name"> <startDate>20.03.2010</startDate> <endDate>29.03.2010</endDate> </event> </event> Now here's my problem. If I update the app and deploy it with Click Once and the app updates it self, I lose the list because the new file is empty. Any workaround this? Here's how I add the Data: var xDocument = XDocument.Load(@"Data\Events.xml"); xDocument.Root.Add(new XElement("event", new XAttribute("name", event.Name), new XElement("startDate", startDate), new XElement("endDate", endDate) ) ); xDocument.Save(@"Data\Events.xml");

  • Custom Parser for JQuery Tablesorter

    - by Tim
    I'm using the jQuery Tablesorter and have an issue with the order in which parsers are applied against table columns. I'm adding a custom parser to handle currency of the form $-3.33. $.tablesorter.addParser({ id: "fancyCurrency", is: function(s) { return /^\$[\-]?[0-9,\.]*$/.test(s); }, format: function(s) { s = s.replace(/[$,]/g,''); return $.tablesorter.formatFloat( s ); }, type: "numeric" }); The problem seems to be that the built-in currency parser takes precedence over my custom parser. I could put the parser in the tablesorter code itself (before the currency parser) and it works properly, but this isn't very maintainable. I can't specify the sorter manually using something like: headers: { 3: { sorter: "fancyNumber" }, 11: { sorter: "fancyCurrency" } } since the table columns are generated dynamically from user inputs. I guess one option would be to specify the sorter to use as a css class and use some JQuery to explicitly specify a sorter like this question suggests, but I'd prefer to stick with dynamic detection if possible.

    Hey, I am trying to parse xml file using Sax parser. let's say xml is like this.. I want to count the number of times b element is present (its variable) And i want this count before parsing, so that I can declare an array of appropriate size. One way is to run count then separately and other way is dynamic array (List Array) Is there any other better way to do this? Also, Is it possible to make an ArrayList of my class..? because I want an array of type myClass.

  • Storing an encrypted cookie with Rails

    - by J. Pablo Fernández
    I need to store a small piece of data (less than 10 characters) in a cookie in Rails and I need it to be secure. I don't want anybody being able to read that piece of data or injecting their own piece of data (as that would open up the app to many kinds of attacks). I think encrypting the contents of the cookie is the way to go (should I also sign it?). What is the best way to do it? Right now I'm doing this, which looks secure, but many things looked secure to people that knew much more than I about security and then it was discovered it wasn't really secure. I'm saving the secret in this way: encryptor = ActiveSupport::MessageEncryptor.new(Example::Application.config.secret_token) cookies[:secret] = { :value => encryptor.encrypt(secret), :domain => "example.com", :secure => !(Rails.env.test? || Rails.env.development?) } and then I'm reading it like this: encryptor = ActiveSupport::MessageEncryptor.new(Example::Application.config.secret_token) secret = encryptor.decrypt(cookies[:secret]) Is that secure? Any better ways of doing it? Update: I know about Rails' session and how it is secure, both by signing the cookie and by optionally storing the contents of the session server side and I do use the session for what it is for. But my question here is about storing a cookie, a piece of information I do not want in the session but I still need it to be secure.

  • http post request with cross-origin in javascript

    - by Calamarico
    i have a problem with a http post call in firefox. I know that when there are a cross origin, firefox first do a OPTIONS before the POST to know the access-control-allow headers. With this code i dont have any problem: Net.requestSpeech.prototype.post = function(url, data) { if(this.xhr != null) { this.xhr.open("POST", url); this.xhr.onreadystatechange = Net.requestSpeech.eventFunction; this.xhr.setRequestHeader("Content-Type", "application/json; charset=utf-8"); this.xhr.send(data); } } I test this code with a simple html that invokes this function. Everything is ok and i have the response of the OPTIONS and POST, and i process the response. But, i'm trying to integrate this code with an existen application with uses jquery (i dont know if this is a problem), when the send(data) executes in this case, the browser (firefox) do the same, first do a OPTION request, but in this case dont receive the response of the server and puts this message in console: [18:48:13.529] OPTIONS http://localhost:8111/ [undefined 31ms] Undefined... the undefined is because dont receive the response, but the code is the same, i dont know why in this case the option dont receive the response, someone have an idea? i debug my server app and the OPTIONS arrive ok to the server, but it seems like the browser dont wait to the response. edit more later: ok i think that the problem is when i run with a simple html with a SCRIPT tag that invokes the method who do the request run ok, but in this app that dont receive the response, i have a form that do a onsubmit event, i think that the submit event returns very fast and the browser dont have time to get the OPTIONS request. edit more later later: WTF, i resolve the problem make the POST request to sync: this.xhr.open("POST", url, false); The submit reponse very quickly and can't wait to the OPTION response of the browser, any idea to this?

  • Inheritance vs specific types in Financial Modelling for cashflows

    - by BlueTrin
    Hello, I have to program some financial applications where I have to represent a schedule of flows. The flows can be of 3 types: - fee flow (just a lump payment at some date) - floating rate flow (the flow is dependant of an interest rate to be determined at a later date) - fixed rate flow (the flow is dependant of an interest rate determined when the deal is done) I need to keep the whole information and I need to represent a schedule of these flows. Originally I wanted to use inheritance and create three classes FeeFlow, FloatingFlow, FixedFlow all inheriting from ICashFlow and implement some method GetFlowType() returning an enum then I could dynamic_cast the object to the correct type. That would allow me to have only one vector to represent my schedule. What do you think of this design, should I rather use three vectors vector, vector and vector to avoid the dynamic casts ?

  • is there something equivalent to 'Address of' or offset operator in .net?

    - by Gio
    We have nested stuctures as such, used as an interface for some device drivers. On occasion we have to update individual elements. An 'address of' operator would be helpful, but an 'offset' function or operator is what I'm really looking for, but not sure how to go about it. In other words, how far is structureN.elementX away from the start of the structure in bytes? [StructLayout(LayoutKind.Sequential)] public struct s1 { UInt16 elem1; UInt16 elem2; UInt16 elem3; } [StructLayout(LayoutKind.Sequential)] public struct s2 { UInt16 elem1; UInt16 elem2; UInt16 elem3; } [StructLayout(LayoutKind.Sequential)] public struct driver { public S1 s1; public S2 s2; } For instance we need to send the device driver some data to update driver.s1.elem3, by way of providing an offset address, data block and length. We would update our local copy, then call the device api with the afore mentioned data. Not sure I have to do this with 'unsafe' method calls. Any help?

  • Design pattern to integrate Rails with a Comet server

    - by empire29
    I have a Ruby on Rails (2.3.5) application and an APE (Ajax Push Engine) server. When records are created within the Rails application, i need to push the new record out on applicable channels to the APE server. Records can be created in the rails app by the traditional path through the controller's create action, or it can be created by several event machines that are constantly monitoring various inputstream and creating records when they see data that meets a certain criteria. It seems to me that the best/right place to put the code that pushes the data out to the APE server (which in turn pushes it out to the clients) is in the Model's after_create hook (since not all record creations will flow through the controller's create action). The final caveat is I want to push a piece of formatted HTML out to the APE server (rather than a JSON representation of the data). The reason I want to do this is 1) I already have logic to produce the desired layout in existing partials 2) I don't want to create a javascript implementation of the partials (javascript that takes a JSON object and creates all the HTML around it for presentation). This would quickly become a maintenance nightmare. The problem with this is it would require "rendering" partials from within the Model (which im having trouble doing anyhow because they don't seem to have access to Helpers when they're rendered in this manner). Anyhow - Just wondering what the right way to go about organizing all of this is. Thanks

  • ASP.NET MVC. Hot to guess autogenerated id value ?

    - by Andrew Florko
    My web form contains list of dynamic fields that are generated like this: <% for (int i = 0; i < Model.Options.Count; i++) { %> ... <%= Html.Hidden("Options[" + i + "].Id", Model.Options[i].Id)%> <%= Html.CheckBox("Options[" + i + "].Selected", Model.Options[i].Selected)%> ... This maps perfectly on array of controller method parameters as described in Model Binding To A List article. I want to add label for checkboxes to title them, but I have to guess their ids in hmtl layout. Options[" + i + "].Selected turns into Options_0__Selected How can I avoid hardcoding Id generation in-built asp.net mvc rules? Thank you advance.

  • script to dynamically fix ophaned users after db restore

    - by JJgates
    After performing a database restore, I want to run a dynamic script to fix ophaned users. My script below loops through all users that are displayed after executing sp_change_users_login 'report' and apply "alter user [username] with login = [username]" to fix SID conflicts verses static go statements. Although, I'm getting an "incorrect syntax error on line 15." can't figure out why... DECLARE @Username varchar(100), @cmd varchar(100) DECLARE userLogin_cursor CURSOR FAST_FORWARD FOR SELECT UserName = name FROM sysusers WHERE issqluser = 1 and (sid IS NOT NULL AND sid <> 0×0) AND suser_sname(sid) IS NULL ORDER BY name FOR READ ONLY OPEN userLogin_cursor FETCH NEXT FROM userLogin_cursor INTO @Username WHILE @@fetch_status = 0 BEGIN SET @cmd = ‘ALTER USER ‘+@username+‘ WITH LOGIN ‘+@username EXECUTE(@cmd) FETCH NEXT FROM userLogin_cursor INTO @Username END CLOSE userLogin_cursor DEALLOCATE userLogin_cursor
