  • Block element text overflow problem in IE7

    - by Adomas
    I'm making a "sort elements" web game using jQuery, HTML & CSS. While everything works fine in FF, IE8, Opera, Chrome, I'm having problem with IE7 wrapping words inside block elements. Here's how it looks in IE7 (wrong): Link (cannot post images as a new user) In IE8 the box with wrapped text would just expand to fit it whole in one line without any overflows. Sorry, can't give another link as a new user Don't mind the element order as it's random. Elements are dynamically generated by jQuery. HTML code: <div class="ui-sortable" id="area"> <span class="object">: </span> <span class="object">1998- </span> <span class="object">ISSN 1392-4087</span> <span class="object">, </span> <span class="object">. </span> <span class="object">nepriklausomas savaitraštis buhalteriams, finansininkams, auditoriams</span> <span class="object">. </span> <span class="object">. </span> <span class="object">. </span> <span class="object">Vilnius</span> <span class="object">1998- </span> <span class="object"><em>Apskaitos, audito ir mokesciu aktualijos</em></span> </div> CSS code (irrelevant info like fonts & colors removed): #area { min-height: 160px; width: 760px; } .object { display: block; float: left; text-align: center; width: auto; } Any comments on why does IE7 does that? How do I make these spans expand to fit the whole text in one line in IE7 and not wrap the text or make overflows?

  • C#: AutoFixture refactoring

    - by Thomas Jaskula
    Hello, I started to use AutoFixture http://autofixture.codeplex.com/ as my unit tests was bloated with a lot of data setup. I was spending more time on seting up the data than to write my unit test. Here's an example of how my initial unit test looks like (example taken from cargo application sample from DDD blue book) [Test] public void should_create_instance_with_correct_ctor_parameters() { var carrierMovements = new List<CarrierMovement>(); var deparureUnLocode1 = new UnLocode("AB44D"); var departureLocation1 = new Location(deparureUnLocode1, "HAMBOURG"); var arrivalUnLocode1 = new UnLocode("XX44D"); var arrivalLocation1 = new Location(arrivalUnLocode1, "TUNIS"); var departureDate1 = new DateTime(2010, 3, 15); var arrivalDate1 = new DateTime(2010, 5, 12); var carrierMovement1 = new CarrierMovement(departureLocation1, arrivalLocation1, departureDate1, arrivalDate1); var deparureUnLocode2 = new UnLocode("CXRET"); var departureLocation2 = new Location(deparureUnLocode2, "GDANSK"); var arrivalUnLocode2 = new UnLocode("ZEZD4"); var arrivalLocation2 = new Location(arrivalUnLocode2, "LE HAVRE"); var departureDate2 = new DateTime(2010, 3, 18); var arrivalDate2 = new DateTime(2010, 3, 31); var carrierMovement2 = new CarrierMovement(departureLocation2, arrivalLocation2, departureDate2, arrivalDate2); carrierMovements.Add(carrierMovement1); carrierMovements.Add(carrierMovement2); new Schedule(carrierMovements).ShouldNotBeNull(); } Here's how I tried to refactor it with AutoFixture [Test] public void should_create_instance_with_correct_ctor_parameters_AutoFixture() { var fixture = new Fixture(); fixture.Register(() => new UnLocode(UnLocodeString())); var departureLoc = fixture.CreateAnonymous<Location>(); var arrivalLoc = fixture.CreateAnonymous<Location>(); var departureDateTime = fixture.CreateAnonymous<DateTime>(); var arrivalDateTime = fixture.CreateAnonymous<DateTime>(); fixture.Register<Location, Location, DateTime, DateTime, CarrierMovement>( (departure, arrival, departureTime, arrivalTime) => new CarrierMovement(departureLoc, arrivalLoc, departureDateTime, arrivalDateTime)); var carrierMovements = fixture.CreateMany<CarrierMovement>(50).ToList(); fixture.Register<List<CarrierMovement>, Schedule>((carrierM) => new Schedule(carrierMovements)); var schedule = fixture.CreateAnonymous<Schedule>(); schedule.ShouldNotBeNull(); } private static string UnLocodeString() { var stringBuilder = new StringBuilder(); for (int i = 0; i < 5; i++) stringBuilder.Append(GetRandomUpperCaseCharacter(i)); return stringBuilder.ToString(); } private static char GetRandomUpperCaseCharacter(int seed) { return ((char)((short)'A' + new Random(seed).Next(26))); } I would like to know if there's better way to refactor it. Would like to do it shorter and easier than that. Thanks in advance for your help.

  • Jquery: How do i not select a specific column

    - by Poku
    I have a table, where i have a click event on the tr: <tr id="<%= candidate.AnsogerID %>" class="newCandidatesTableTr"> , this click event: $(".newCandidatesTableTr").click(function(e) { works just fine, but in the row i also have a click event on a td: $(".insertCandidate").live("click", (function(e) { and this conflicts eachother. I want to do one thing if the tr is clicked and other when this specific td in the tr is clicked. So how do i in my tr.click() event defined that the event shall not happend when i click the specific td? Here is the code: // Lists a table with old candidates who migth be the same person as the new candidate $(".newCandidatesTableTr").click(function(e) { alert(this.id); GetCandidateName(this.id); }); // Show insert candidate dialog $(".insertCandidate").live("click", (function(e) { var tempCanName = $(".suggentionCandidatesTableTitle").text(); var tempCanNameSub = tempCanName.substr(0, tempCanName.length - 1); var canName = $(".suggentionCandidateName_" + canID + "").text(); $("#mergeCandidateDialog").empty(); $.blockUI({ message: $("#mergeCandidateDialog").append( "<div>" + tempCanNameSub + "'s ansøgning vil blive lagt under den eksiterende ansøger " + canName + "'s data.<br /><br /> Ønsker du at fortsætte?<br /><br /></div>" + "<div id=\"content\">" + "<input type=\"button\" id=\"" + this.id + "\" class=\"insertCandidateYes\" value=\"Ja\" />" + "<input type=\"button\" id=\"insertCandidateNo\" value=\"Nej\" /></div>"), css: { cursor: 'default', fontWeight: 'normal', padding: '7px', textAlign: 'left' } }); })); <% foreach (var candidate in Model.Ansogninger) { %> <tr id="<%= candidate.AnsogerID %>" class="newCandidatesTableTr"> <td><div id="candidateID""><label title="<%= candidate.Navn %>"><%= candidate.AnsogerID %></label></div></td> <td><div id="<%= "candidateName_" + candidate.AnsogerID %>" class="candidateNameTD"><%= candidate.Navn %></div></td> <td><div id="candidateEmail"><%= candidate.Email %></div></td> <td><div id="candidateRundeName"><%= Model.RundeName %></div></td> <td id="testTD"> <div id="<%= "acceptCandidateButton_" + candidate.AnsogerID %>" class="acceptb">Godkend</div> </td> </tr> <% } %>

  • Creating a music catalog in C# and extracting first 30 seconds as soon as the first words are sung

    - by Rad
    I already read a question: Separation of singing voice from music. I don’t need this complex audio processing. I only need some detection mechanism that would detect that there is some voice/vocal playing while the music is playing (or not playing) I need to extract first 30 seconds when a vocalist starts singing along with full band music. See question 2 below. I want to create a music catalog using ASP.NET MVC 2 and Silverlight clients and C#.NET 4.0 programming language that would be front store. On the backend I would also like to create a desktop WPF/Windows application to create the music catalog from already existing music files, most of which have metadata in them ID3v1, ID3v2.3, ID3v2.4, iTunes MP4, WMA, Vorbis Comments and APE Tags etc. I would possibly like to create a web service that would allow catalog contributors to upload a zipped album and trigger metadata extraction of music data and extraction of music segments as described below. I would be happy if I achieve no. 1 below. Let's say I have 1000ths of songs in mp3 (or other formats) grouped in subfolders using some classification (Genre, Artists, Albums, Composers or other groupings). I want to create tables in DB that would organize songs so they can be searched based on different criteria (year, length, above classification or by song title, description etc) like what iTune store allows to their customers. I want to extract metadata from various formats (I will try to get songs in mp3 format, but there may be other popular formats) and allow music Catalog manager person to add missing data from either desktop or web applications. He or other contributors can upload zipped music via an HTML or Silverlight upload or WPF. Can anybody suggest open source libraries, articles, code snippets that can do that in an automatic way using .NET and possibly SQL Server DB? My main questions are these. This is an audio processing challenge. I want to extract 2 segments of music (questions 1 and 2): 1. How to extract a music segment: 1-2 seconds before a vocal starts singing and up to 30 seconds from that point in time and 2. Much more challenging is to find repeating segments (One would usually find or recognize the names of the songs and songs are usually known by these refrains. How would I go about creating a list of songs that go great together like what Genius from iTune does? Is there any characteristics of music that can be used to match songs? The goal is for people quickly scan and recognize songs i.e. associate melody, words with a title/album so they can make intelligent decisions like buying a song, create similar mood songs. Thanks, Rad

  • How to delete multiple files with msbuild/web deployment project?

    - by Alex
    I have an odd issue with how msbuild is behaving with a VS2008 Web Deployment Project and would like to know why it seems to randomly misbehave. I need to remove a number of files from a deployment folder that should only exist in my development environment. The files have been generated by the web application during dev/testing and are not included in my Visual Studio project/solution. The configuration I am using is as follows: <!-- Partial extract from Microsoft Visual Studio 2008 Web Deployment Project --> <ItemGroup> <DeleteAfterBuild Include="$(OutputPath)data\errors\*.xml" /> <!-- Folder 1: 36 files --> <DeleteAfterBuild Include="$(OutputPath)data\logos\*.*" /> <!-- Folder 2: 2 files --> <DeleteAfterBuild Include="$(OutputPath)banners\*.*" /> <!-- Folder 3: 1 file --> </ItemGroup> <Target Name="AfterBuild"> <Message Text="------ AfterBuild process starting ------" Importance="high" /> <Delete Files="@(DeleteAfterBuild)"> <Output TaskParameter="DeletedFiles" PropertyName="deleted" /> </Delete> <Message Text="DELETED FILES: $(deleted)" Importance="high" /> <Message Text="------ AfterBuild process complete ------" Importance="high" /> </Target> The problem I have is that when I do a build/rebuild of the Web Deployment Project it "sometimes" removes all the files but other times it will not remove anything! Or it will remove only one or two of the three folders in the DeleteAfterBuild item group. There seems to be no consistency in when the build process decides to remove the files or not. When I've edited the configuration to include only Folder 1 (for example), it removes all the files correctly. Then adding Folder 2 and 3, it starts removing all the files as I want. Then, seeming at random times, I'll rebuild the project and it won't remove any of the files! I have tried moving these items to the ExcludeFromBuild item group (which is probably where it should be) but it gives me the same unpredictable result. Has anyone experienced this? Am I doing something wrong? Why does this happen?

  • How can I use functools.partial on multiple methods on an object, and freeze parameters out of order

    - by Joseph Garvin
    I find functools.partial to be extremely useful, but I would like to be able to freeze arguments out of order (the argument you want to freeze is not always the first one) and I'd like to be able to apply it to several methods on a class at once, to make a proxy object that has the same methods as the underlying object except with some of its methods parameter being frozen (think of it as generalizing partial to apply to classes). I've managed to scrap together a version of functools.partial called 'bind' that lets me specify parameters out of order by passing them by keyword argument. That part works: >>> def foo(x, y): ... print x, y ... >>> bar = bind(foo, y=3) >>> bar(2) 2 3 But my proxy class does not work, and I'm not sure why: >>> class Foo(object): ... def bar(self, x, y): ... print x, y ... >>> a = Foo() >>> b = PureProxy(a, bar=bind(Foo.bar, y=3)) >>> b.bar(2) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: bar() takes exactly 3 arguments (2 given) I'm probably doing this all sorts of wrong because I'm just going by what I've pieced together from random documentation, blogs, and running dir() on all the pieces. Suggestions both on how to make this work and better ways to implement it would be appreciated ;) One detail I'm unsure about is how this should all interact with descriptors. Code follows. from types import MethodType class PureProxy(object): def __init__(self, underlying, **substitutions): self.underlying = underlying for name in substitutions: subst_attr = substitutions[name] if hasattr(subst_attr, "underlying"): setattr(self, name, MethodType(subst_attr, self, PureProxy)) def __getattribute__(self, name): return getattr(object.__getattribute__(self, "underlying"), name) def bind(f, *args, **kwargs): """ Lets you freeze arguments of a function be certain values. Unlike functools.partial, you can freeze arguments by name, which has the bonus of letting you freeze them out of order. args will be treated just like partial, but kwargs will properly take into account if you are specifying a regular argument by name. """ argspec = inspect.getargspec(f) argdict = copy(kwargs) if hasattr(f, "im_func"): f = f.im_func args_idx = 0 for arg in argspec.args: if args_idx >= len(args): break argdict[arg] = args[args_idx] args_idx += 1 num_plugged = args_idx def new_func(*inner_args, **inner_kwargs): args_idx = 0 for arg in argspec.args[num_plugged:]: if arg in argdict: continue if args_idx >= len(inner_args): # We can't raise an error here because some remaining arguments # may have been passed in by keyword. break argdict[arg] = inner_args[args_idx] args_idx += 1 f(**dict(argdict, **inner_kwargs)) new_func.underlying = f return new_func

  • BindException/Too many file open while using HttpClient under load

    - by Langali
    I have got 1000 dedicated Java threads where each thread polls a corresponding url every one second. public class Poller { public static Node poll(Node node) { GetMethod method = null; try { HttpClient client = new HttpClient(new SimpleHttpConnectionManager(true)); ...... } catch (IOException ex) { ex.printStackTrace(); } finally { method.releaseConnection(); } } } The threads are run every one second: for (int i=0; i <1000; i++) { MyThread thread = threads.get(i) // threads is a static field if(thread.isAlive()) { // If the previous thread is still running, let it run. } else { thread.start(); } } The problem is if I run the job every one second I get random exceptions like these: java.net.BindException: Address already in use INFO httpclient.HttpMethodDirector: I/O exception (java.net.BindException) caught when processing request: Address already in use INFO httpclient.HttpMethodDirector: Retrying request But if I run the job every 2 seconds or more, everything runs fine. I even tried shutting down the instance of SimpleHttpConnectionManager() using shutDown() with no effect. If I do netstat, I see thousands of TCP connections in TIME_WAIT state, which means they are have been closed and are clearing up. So to limit the no of connections, I tried using a single instance of HttpClient and use it like this: public class MyHttpClientFactory { private static MyHttpClientFactory instance = new HttpClientFactory(); private MultiThreadedHttpConnectionManager connectionManager; private HttpClient client; private HttpClientFactory() { init(); } public static HttpClientFactory getInstance() { return instance; } public void init() { connectionManager = new MultiThreadedHttpConnectionManager(); HttpConnectionManagerParams managerParams = new HttpConnectionManagerParams(); managerParams.setMaxTotalConnections(1000); connectionManager.setParams(managerParams); client = new HttpClient(connectionManager); } public HttpClient getHttpClient() { if (client != null) { return client; } else { init(); return client; } } } However after running for exactly 2 hours, it starts throwing 'too many open files' and eventually cannot do anything at all. ERROR java.net.SocketException: Too many open files INFO httpclient.HttpMethodDirector: I/O exception (java.net.SocketException) caught when processing request: Too many open files INFO httpclient.HttpMethodDirector: Retrying request I should be able to increase the no of connections allowed and make it work, but I would just be prolonging the evil. Any idea what is the best practise to use HttpClient in a situation like above? Btw, I am still on HttpClient3.1.

  • merging UIImagePickerController image with cameraOverlayView

    - by GameDev
    Im really in the need for some help and advice. Spent the last week on this and have now just become frustrated as i cant get it to work! Basically, im trying to merge two images into one image to display/save. First the user picks an image from album, it goes to edit image screen where user can move and scale the image. On this screen is an overlay image (320x480) for the person to align there eyes in. Once aligned I want to save this image (edited and overlay) into one and pass the image onto my next screen. It works fine when the image is filling the edit/crop box, but when the image is widescreen with top and bottom not filling the box, then when i save the image the coords of the overlay dont get saved correctly! Heres my code, ive tried various ways of doing this but have failed at every attempt :( - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Access the cropped image from info dictionary UIImage *image = [info objectForKey:@"UIImagePickerControllerEditedImage"]; // Combine image with overlay before saving!! image = [self addOverlayToImage:image]; overlayGraphicView.image = nil; // Take the picture image to the post picture view controller postPictureView = [[PostPictureViewController alloc] init:image Company:companyName withLink:buyButtonLink]; [picker pushViewController:postPictureView animated:YES]; [picker release],picker = nil; } The problem is that the image picked (originalImage) could be of any height, my overlayImage is however always 320x480, its almost all transparent with just two eye images in center which i want to save over the original images eyes! - (UIImage*) addOverlayToImage:(UIImage*)originalImage { CGRect cgRect =[[UIScreen mainScreen] bounds]; CGSize size = cgRect.size; UIGraphicsBeginImageContext(size); [originalImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage* overlayImage = [UIImage imageNamed:overlayGraphicName]; [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage *finalImage = UIGraphicsGetImageFromCurrentImageContext(); [finalImage retain]; UIGraphicsEndImageContext(); return finalImage; } I wish there was just an easy way to take a screenshot of whatever is in the edit crop box :( Please if someone could help me with this ASAP as I need to finish this in 1-2 days time! Thank you. EDIT:- I should also mention that with this I get the correct center of the screen and placement of the overlay on my next screen: [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; However, I am unable to work out the correct position of the main image especially as the height is different for every image if not fullscreen! I tried this to center it into the correct position but it doesnt work: [originalImage drawInRect:CGRectMake(0,(size.height/2 - originalImage.size.height/2), originalImage.size.width, originalImage.size.height)];

  • Bullet indents in PowerPoint 2007 compatibility mode via .NET interop issue

    - by L. Shaydariv
    Hello. I've got a really difficult bug and I can't see the fix. The subject drives me insane for real for a long time. Let's consider the following scenario: 1) There is a PowerPoint 2003 presentation. It contains the only slide and the only shape, but the shape contains a text frame including a bulleted list with a random textual representation structure. 2) There is a requirement to get bullet indents for every bulletted paragraph using PowerPoint 2007. I can satisfy the requirement opening the presentation in the compatibility mode and applying the following VBA script: With ActivePresentation Dim sl As Slide: Set sl = .Slides(1) Dim sh As Shape: Set sh = sl.Shapes(1) Dim i As Integer For i = 1 To sh.TextFrame.TextRange.Paragraphs.Count Dim para As TextRange: Set para = sh.TextFrame.TextRange.Paragraphs(i, 1) Debug.Print para.Text; para.indentLevel, sh.TextFrame.Ruler.Levels(para.indentLevel).FirstMargin Next i End With that produces the following output: A 1 0 B 1 0 C 2 24 D 3 60 E 5 132 Obviously, everything is perfect indeed: it has shown the proper list item text, list item level and its bullet indent. But I can't see the way of how I can reach the same result using C#. Let's add a COM-reference to Microsoft.Office.Interop.PowerPoint 2.9.0.0 (taken from MSPPT.OLB, MS Office 12): // presentation = ...("presentation.ppt")... // a PowerPoint 2003 presentation Slide slide = presentation.Slides[1]; Shape shape = slide.Shapes[1]; for (int i = 1; i<=shape.TextFrame.TextRange.Paragraphs(-1, -1).Count; i++) { TextRange paragraph = shape.TextFrame.TextRange.Paragraphs(i, 1); Console.WriteLine("{0} {1} {2}", paragraph.Text, paragraph.IndentLevel, shape.TextFrame.Ruler.Levels[paragraph.IndentLevel].FirstMargin); } Oh, man... What's it? I've got problems here. First, the paragraph.Text value is trimmed until the '\r' character is found (however paragraph.Text[0] really returns the first character O_o). But it's ok, I can shut my eyes to this. But... But, second, I can't understand why the first margins are always zero and it does not matter which level they belong to. They are always zero in the compatibility mode... It's hard to believe it... :) So is there any way to fix it or just to find a workaround? I'd like to accept any help regarding to the solution of the subject. I can't even find any article related to the issue. :( Probably you have ever been face to face with it... Or is it just a bug with no fix and must it be reported to Microsoft? Thanks you.

  • Delaying emails in PHP to avoid exceeding server limit

    - by Andrew P.
    Okay, so here's my problem: I have a list of members on a website, and periodically one of the admins my site (who are not very web or tech savvy) will send a newsletter to the memberlist. My current memberlist is well over 800 individuals long. So, I wrote an email script that sends the email to the full memberlist, with the members listed in the Bcc header. However, I've discovered that my host server has a limit of 300 emails per hour, which I apparently exceed even though the members are listed in the Bcc field. (I wasn't previously aware that the behaviour of Bcc was to send separate emails for each name on the list...) After some thought, I've come to the conclusion that my only solution is to have my script send only the email to only the first 300 emails, wait an hour, and send a second email to the next three hundred, wait another hour, and so on until I've sent the email to the whole member list. Looking around on the internet, I've seen some other solutions people have come up with for delaying emails in PHP. Sleep() is obviously not an option, because I can't just leave the script open and running for 3 or four hours. I've seen some people suggest cron jobs, but I'm not sure how feasible it would be to create three new cron jobs every time I send an email, use them once, and then delete them afterward. The final (and what I think is the smartest) solution I've seen, is to have a table in my database to temporarily store the emails to be delayed and sent later, and then create a cron job that checks this sql table every hour or so, compares the timestamp of the row to the current timestamp, and then sends the email if an hour has passed. So I'm asking you all which method you would recommend. Is there an easier solution that I've completely looked over (aside from getting a different hosting plan. ha!), or is there a cleaner way to do it than the database / cron job approach? tl;dr: I have 800 emails to send in an hour on a server that limits me to 300/hr. Using PHP, find a way to get around this problem in a way that the person sending the email needs only to click "send."

  • How hard programming is? Really. [closed]

    - by Bubba88
    Hi! The question is about your perception of programming activity. How hard/exacting this task is? There is much buzz about programming nowadays, people say that programmers are smart, very technical and abstract at a time, know much about world, psychology etc.. They say, that programmers got really powerful brain thing, cause there is much to keep in consideration simultaneously again with much information folded into each other associatively (up 10 levels of folding they say))) Still, there are some terms to specify at our own.. So that is the question: What do you think about programming in general? Is it hard? Is it 'for everyone' or for the particular kind of people only? How much non-CS background do you need to program (just to program, really; enterprise applications for example)? How long is the learning curve? (again, for programming in general) And another bunch of random questions: - If you were not to like/love programming, would that be a serious trouble bothering your current employment? - If you were to start from the beginning, would you chose that direction this time? - What other areas (jobs or maybe hobbies) are comparable to programming in the way they can explode someone's lovely brain? - Is 'non turing-complete programming' (SQL, XML, etc.) comparable to what we do or is it really way easier, less requiring, cheap and akin to cooking :)? Well, the essence is: How would you describe programming activity WRT to its difficulty? Or, on the other hand: Did you ever catch yourself thinking at some point: OMG, it's sooo hard! I don't know how would I ever program, even carried away this way and doing programming just for fun? It's very interesting to know your opinion, your'e the programmers after all. I mean much people must be exaggerating/speculating about the thing they do not really know about. But that musn't be the case here on SO :) P.S.: I'll try my best to update this post later, and you please edit it too. At least I'll get decent English in my question text :)

  • How to I serialize a large graph of .NET object into a SQL Server BLOB without creating a large bu

    - by Ian Ringrose
    We have code like: ms = New IO.MemoryStream bin = New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bin.Serialize(ms, largeGraphOfObjects) dataToSaveToDatabase = ms.ToArray() // put dataToSaveToDatabase in a Sql server BLOB But the memory steam allocates a large buffer from the large memory heap that is giving us problems. So how can we stream the data without needing enough free memory to hold the serialized objects. I am looking for a way to get a Stream from SQL server that can then be passed to bin.Serialize() so avoiding keeping all the data in my processes memory. Likewise for reading the data back... Some more background. This is part of a complex numerical processing system that processes data in near real time looking for equipment problems etc, the serialization is done to allow a restart when there is a problem with data quality from a data feed etc. (We store the data feeds and can rerun them after the operator has edited out bad values.) Therefore we serialize the object a lot more often then we de-serialize them. The objects we are serializing include very large arrays mostly of doubles as well as a lot of small “more normal” objects. We are pushing the memory limit on a 32 bit system and make the garage collector work very hard. (Effects are being made elsewhere in the system to improve this, e.g. reusing large arrays rather then create new arrays.) Often the serialization of the state is the last straw that courses an out of memory exception; our peak memory usage is while this serialization is being done. I think we get large memory pool fragmentation when we de-serialize the object, I expect there are also other problem with large memory pool fragmentation given the size of the arrays. (This has not yet been investigated, as the person that first looked at this is a numerical processing expert, not a memory management expert.) Are customers use a mix of Sql Server 2000, 2005 and 2008 and we would rather not have different code paths for each version of Sql Server if possible. We can have many active models at a time (in different process, across many machines), each model can have many saved states. Hence the saved state is stored in a database blob rather then a file. As the spread of saving the state is important, I would rather not serialize the object to a file, and then put the file in a BLOB one block at a time. Other related questions I have asked How to Stream data from/to SQL Server BLOB fields? Is there a SqlFileStream like class that works with Sql Server 2005?

  • AutoFixture refactoring

    - by Thomas Jaskula
    I started to use AutoFixture http://autofixture.codeplex.com/ as my unit tests was bloated with a lot of data setup. I was spending more time on seting up the data than to write my unit test. Here's an example of how my initial unit test looks like (example taken from cargo application sample from DDD blue book) [Test] public void should_create_instance_with_correct_ctor_parameters() { var carrierMovements = new List<CarrierMovement>(); var deparureUnLocode1 = new UnLocode("AB44D"); var departureLocation1 = new Location(deparureUnLocode1, "HAMBOURG"); var arrivalUnLocode1 = new UnLocode("XX44D"); var arrivalLocation1 = new Location(arrivalUnLocode1, "TUNIS"); var departureDate1 = new DateTime(2010, 3, 15); var arrivalDate1 = new DateTime(2010, 5, 12); var carrierMovement1 = new CarrierMovement(departureLocation1, arrivalLocation1, departureDate1, arrivalDate1); var deparureUnLocode2 = new UnLocode("CXRET"); var departureLocation2 = new Location(deparureUnLocode2, "GDANSK"); var arrivalUnLocode2 = new UnLocode("ZEZD4"); var arrivalLocation2 = new Location(arrivalUnLocode2, "LE HAVRE"); var departureDate2 = new DateTime(2010, 3, 18); var arrivalDate2 = new DateTime(2010, 3, 31); var carrierMovement2 = new CarrierMovement(departureLocation2, arrivalLocation2, departureDate2, arrivalDate2); carrierMovements.Add(carrierMovement1); carrierMovements.Add(carrierMovement2); new Schedule(carrierMovements).ShouldNotBeNull(); } Here's how I tried to refactor it with AutoFixture [Test] public void should_create_instance_with_correct_ctor_parameters_AutoFixture() { var fixture = new Fixture(); fixture.Register(() => new UnLocode(UnLocodeString())); var departureLoc = fixture.CreateAnonymous<Location>(); var arrivalLoc = fixture.CreateAnonymous<Location>(); var departureDateTime = fixture.CreateAnonymous<DateTime>(); var arrivalDateTime = fixture.CreateAnonymous<DateTime>(); fixture.Register<Location, Location, DateTime, DateTime, CarrierMovement>( (departure, arrival, departureTime, arrivalTime) => new CarrierMovement(departureLoc, arrivalLoc, departureDateTime, arrivalDateTime)); var carrierMovements = fixture.CreateMany<CarrierMovement>(50).ToList(); fixture.Register<List<CarrierMovement>, Schedule>((carrierM) => new Schedule(carrierMovements)); var schedule = fixture.CreateAnonymous<Schedule>(); schedule.ShouldNotBeNull(); } private static string UnLocodeString() { var stringBuilder = new StringBuilder(); for (int i = 0; i < 5; i++) stringBuilder.Append(GetRandomUpperCaseCharacter(i)); return stringBuilder.ToString(); } private static char GetRandomUpperCaseCharacter(int seed) { return ((char)((short)'A' + new Random(seed).Next(26))); } I would like to know if there's better way to refactor it. Would like to do it shorter and easier than that.

  • Stumbleupon type query...

    - by Chris Denman
    Wow, makes your head spin! I am about to start a project, and although my mySql is OK, I can't get my head around what required for this: I have a table of web addresses. id,url 1,http://www.url1.com 2,http://www.url2.com 3,http://www.url3.com 4,http://www.url4.com I have a table of users. id,name 1,fred bloggs 2,john bloggs 3,amy bloggs I have a table of categories. id,name 1,science 2,tech 3,adult 4,stackoverflow I have a table of categories the user likes as numerical ref relating to the category unique ref. For example: user,category 1,4 1,6 1,7 1,10 2,3 2,4 3,5 . . . I have a table of scores relating to each website address. When a user visits one of these sites and says they like it, it's stored like so: url_ref,category 4,2 4,3 4,6 4,2 4,3 5,2 5,3 . . . So based on the above data, URL 4 would score (in it's own right) as follows: 2=2 3=2 6=1 What I was hoping to do was pick out a random URL from over 2,000,000 records based on the current users interests. So if the logged in user likes categories 1,2,3 then I would like to ORDER BY a score generated based on their interest. If the logged in user likes categories 2 3 and 6 then the total score would be 5. However, if the current logged in user only like categories 2 and 6, the URL score would be 3. So the order by would be in context of the logged in users interests. Think of stumbleupon. I was thinking of using a set of VIEWS to help with sub queries. I'm guessing that all 2,000,000 records will need to be looked at and based on the id of the url it will look to see what scores it has based on each selected category of the current user. So we need to know the user ID and this gets passed into the query as a constant from the start. Ain't got a clue! Chris Denman

  • Best Practices / Patterns for Enterprise Protection/Remediation of SSNs (Social Security Numbers)

    - by Erik Neu
    I am interested in hearing about enterprise solutions for SSN handling. (I looked pretty hard for any pre-existing post on SO, including reviewing the terriffic SO automated "Related Questions" list, and did not find anything, so hopefully this is not a repeat.) First, I think it is important to enumerate the reasons systems/databases use SSNs: (note—these are reasons for de facto current state—I understand that many of them are not good reasons) Required for Interaction with External Entities. This is the most valid case—where external entities your system interfaces with require an SSN. This would typically be government, tax and financial. SSN is used to ensure system-wide uniqueness. SSN has become the default foreign key used internally within the enterprise, to perform cross-system joins. SSN is used for user authentication (e.g., log-on) The enterprise solution that seems optimum to me is to create a single SSN repository that is accessed by all applications needing to look up SSN info. This repository substitutes a globally unique, random 9-digit number (ASN) for the true SSN. I see many benefits to this approach. First of all, it is obviously highly backwards-compatible—all your systems "just" have to go through a major, synchronized, one-time data-cleansing exercise, where they replace the real SSN with the alternate ASN. Also, it is centralized, so it minimizes the scope for inspection and compliance. (Obviously, as a negative, it also creates a single point of failure.) This approach would solve issues 2 and 3, without ever requiring lookups to get the real SSN. For issue #1, authorized systems could provide an ASN, and be returned the real SSN. This would of course be done over secure connections, and the requesting systems would never persist the full SSN. Also, if the requesting system only needs the last 4 digits of the SSN, then that is all that would ever be passed. Issue #4 could be handled the same way as issue #1, though obviously the best thing would be to move away from having users supply an SSN for log-on. There are a couple of papers on this: UC Berkely: http://bit.ly/bdZPjQ Oracle Vault: bit.ly/cikbi1

  • WordPress Write Cache Problem with Multiple Sessions

    - by Volomike
    I'm working on a content dripper custom plugin in WordPress that my client asked me to build. He says he wants it to catch a page view event, and if it's the right time of day (24 hours since last post), to pull from a resource file and output another post. He needed it to also raise a flag and prevent other sessions from firing that same snippet of code. So, raise some kind of flag saying, "I'm posting that post, go away other process," and then it makes that post and releases the flag again. However, the strangest thing is occurring when placed under load with multiple sessions hitting the site with page views. It's firing instead of one post -- it's randomly doing like 1, 2, or 3 extra posts, with each one thinking that it was the right time to post because it was 24 hours past the time of the last post. Because it's somewhat random, I'm guessing that the problem is some kind of write caching where the other sessions don't see the raised flag just yet until a couple microseconds pass. The plugin was raising the "flag" by simply writing to the wp_options table with the update_option() API in WordPress. The other user sessions were supposed to read that value with get_option() and see the flag, and then not run that piece of code that creates the post because a given session was already doing it. Then, when done, I lower the flag and the other sessions continue as normal. But what it's doing is letting those other sessions in. To make this work, I was using add_action('loop_start','checkToAddContent'). The odd thing about that function though is that it's called more than once on a page, and in fact some plugins may call it. I don't know if there's a better event to hook. Even still, even if I find an event to hook that only runs once on a page view, I still have multiple sessions to contend with (different users who may view the page at the same time) and I want only one given session to trigger the content post when the post is due on the schedule. I'm wondering if there are any WordPress plugin devs out there who could suggest another event hook to latch on to, and to figure out another way to raise a flag that all sessions would see. I mean, I could use the shared memory API in PHP, but many hosting plans have that disabled. Can't use a cookie or session var because that's only one single session. About the only thing that might work across hosting plans would be to drop a file as a flag, instead. If the file is present, then one session has the flag. If the file is not present, then other sessions can attempt to get the flag. Sure, I could use the file route, but it's kind of immature in my opinion and I was wondering if there's something in WordPress I could do.

  • What could cause a Labwindows/CVI C program to hate the number 2573?

    - by Adam Bard
    Using Windows So I'm reading from a binary file a list of unsigned int data values. The file contains a number of datasets listed sequentially. Here's the function to read a single dataset from a char* pointing to the start of it: function read_dataset(char* stream, t_dataset *dataset){ //...some init, including setting dataset->size; for(i=0;i<dataset->size;i++){ dataset->samples[i] = *((unsigned int *) stream); stream += sizeof(unsigned int); } //... } Where read_dataset in such a context as this: //... char buff[10000]; t_dataset* dataset = malloc( sizeof( *dataset) ); unsigned long offset = 0; for(i=0;i<number_of_datasets; i++){ fseek(fd_in, offset, SEEK_SET); if( (n = fread(buff, sizeof(char), sizeof(*dataset), fd_in)) != sizeof(*dataset) ){ break; } read_dataset(buff, *dataset); // Do something with dataset here. It's screwed up before this, I checked. offset += profileSize; } //... Everything goes swimmingly until my loop reads the number 2573. All of a sudden it starts spitting out random and huge numbers. For example, what should be ... 1831 2229 2406 2637 2609 2573 2523 2247 ... becomes ... 1831 2229 2406 2637 2609 0xDB00000A 0xC7000009 0xB2000008 ... If you think those hex numbers look suspicious, you're right. Turns out the hex values for the values that were changed are really familiar: 2573 -> 0xA0D 2523 -> 0x9DB 2247 -> 0x8C7 So apparently this number 2573 causes my stream pointer to gain a byte. This remains until the next dataset is loaded and parsed, and god forbid it contain a number 2573. I have checked a number of spots where this happens, and each one I've checked began on 2573. I admit I'm not so talented in the world of C. What could cause this is completely and entirely opaque to me.

  • cuda/thrust: Trying to sort_by_key 2.8GB of data in 6GB of gpu RAM throws bad_alloc

    - by Sven K
    I have just started using thrust and one of the biggest issues I have so far is that there seems to be no documentation as to how much memory operations require. So I am not sure why the code below is throwing bad_alloc when trying to sort (before the sorting I still have 50% of GPU memory available, and I have 70GB of RAM available on the CPU)--can anyone shed some light on this? #include <thrust/device_vector.h> #include <thrust/sort.h> #include <thrust/random.h> void initialize_data(thrust::device_vector<uint64_t>& data) { thrust::fill(data.begin(), data.end(), 10); } #define BUFFERS 3 int main(void) { size_t N = 120 * 1024 * 1024; char line[256]; try { std::cout << "device_vector" << std::endl; typedef thrust::device_vector<uint64_t> vec64_t; // Each buffer is 900MB vec64_t c[3] = {vec64_t(N), vec64_t(N), vec64_t(N)}; initialize_data(c[0]); initialize_data(c[1]); initialize_data(c[2]); std::cout << "initialize_data finished...

  • WPF Application Slow Unresponsive when demonstrating using remote sharing software

    - by Kev
    After spending 14 hours on this I think its time to share my woes and see if anyone has experienced this issue before. Ill describe the issue and tests I have done to rule out certain things. Ok so I have a WPF application which loads in data from an SQL database. I am using DevExpress Components for datagrids, ribbons etc.. and FluentNhibernate to provide a session for database operations. I am also using log4net to log events to a textfile. Using the application on my laptop with SQL Express 2008 works fine.. the application starts up, retrieves 1000 records and I can tab through the controls on the ribbon. Now, I decided to demo the application to a third party and used remote login/sharing software online to share my desktop with the other person so as I could load the application on my laptop and they could view me using the application. Now, the application takes approx 45 seconds to load... 30 seconds with a blank database where as, when im not sharing out my screen using the online software the application loads in about 7-10 seconds. As well as that, even using the controls in the application during the demo were very sticky, slow and unresponsive. During the sharing session though however I was able to use other applications without any problems.. everything else worked fine. But I cannot understand how my application works ok under normal conditions , even browsing the net at the same time etc... BUT totally fails to perform correctly when I am sharing a session with another user... the CPU usage shot up to 100% too at times when the application was trying to start up... Please see below a list of 3rd party dlls I am using as references in my project. DevExpress dlls FluidKit PixelLab.WPF PixelLab.Common Galasoft WPF Kit FluentNHibernate NHibernate Nhibernate.ByteCode.Castle Skype4ComLib TXTEXTControl log4net LinqKit All of these DLLs are in the output folder with the application dlls created from the class assemblys in the project. So when installed via an installer on a machine the dlls will be in the same application folder as the application file itself. Many thanks

  • What to Return? Error String, Bool with Error String Out, or Void with Exception

    - by Ranger Pretzel
    I spend most of my time in C# and am trying to figure out which is the best practice for handling an exception and cleanly return an error message from a called method back to the calling method. For example, here is some ActiveDirectory authentication code. Please imagine this Method as part of a Class (and not just a standalone function.) bool IsUserAuthenticated(string domain, string user, string pass, out errStr) { bool authentic = false; try { // Instantiate Directory Entry object DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, user, pass); // Force connection over network to authenticate object nativeObject = entry.NativeObject; // No exception thrown? We must be good, then. authentic = true; } catch (Exception e) { errStr = e.Message().ToString(); } return authentic; } The advantages of doing it this way are a clear YES or NO that you can embed right in your If-Then-Else statement. The downside is that it also requires the person using the method to supply a string to get the Error back (if any.) I guess I could overload this method with the same parameters minus the "out errStr", but ignoring the error seems like a bad idea since there can be many reasons for such a failure... Alternatively, I could write a method that returns an Error String (instead of using "out errStr") in which a returned empty string means that the user authenticated fine. string AuthenticateUser(string domain, string user, string pass) { string errStr = ""; try { // Instantiate Directory Entry object DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, user, pass); // Force connection over network to authenticate object nativeObject = entry.NativeObject; } catch (Exception e) { errStr = e.Message().ToString(); } return errStr; } But this seems like a "weak" way of doing things. Or should I just make my method "void" and just not handle the exception so that it gets passed back to the calling function? void AuthenticateUser(string domain, string user, string pass) { // Instantiate Directory Entry object DirectoryEntry entry = new DirectoryEntry("LDAP://" + domain, user, pass); // Force connection over network to authenticate object nativeObject = entry.NativeObject; } This seems the most sane to me (for some reason). Yet at the same time, the only real advantage of wrapping those 2 lines over just typing those 2 lines everywhere I need to authenticate is that I don't need to include the "LDAP://" string. The downside with this way of doing it is that the user has to put this method in a try-catch block. Thoughts? Is there another way of doing this that I'm not thinking of?

  • HTML wrapper div over embedded flash object cannot be "clickable" by jQuery

    - by Michael Mao
    Hi all: I've been trying to do as the client requested : redirect to campaign page then to destination page once a customer clicks on the top banner in swf format. You can check what's been done at :http://ausdcf.org If you are using Firefox, Chrome or Safari, I suspect you can reach the destination page. However, if you are using IE or Opera, I doubt it. I think to cause of such a weird problem is: The swf ojbects don't have a link to url, SO I have to hack the theme template file like this : <div id="header">'; /* * A quick and dirty way to put some swf into PHP, and rotate among them ... */ //available banners $banners = array( 'http://localhost/smf/flash/banner_fertalign_1.swf', 'http://localhost/smf/flash/banner_fertalign_2.swf', 'http://localhost/smf/flash/banner_fertalign_3.swf' ); //get random banner srand((double) microtime() * 1000000); $rand = rand(0,count($banners)-1); echo '<div id="top_banner_clickable">'; echo '<div id="top_banner_wrapper">'; echo '<object width="400" height="60">'; echo '<param name="wmode" value="transparent">'; echo '<embed wmode="transparent" src="'.$banners[$rand].'" '; echo 'width="400" height="60" type="application/x-shockwave-flash"'; echo 'pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" />'; echo '</object>'; echo '</div>'; echo '</div>'; And the related jQuery code is like this: /* master.js */ $(document).ready(function() { $("#top_banner_clickable").click(function() { window.location ="http://ausdcf.org/campaign/"; }); }); I absolutely know nothing about Flash or embedded objects. I guess that's the cause of this problem. Plus, I don't know why it works with some browsers but not all... I even tried to add a z-index to the wrapper div in css like this: #top_banner_clickable { z-index : 100; } No this wouldn't do, either... Is there a way to go around this issue? Many thanks in advance.

  • Proper binding data to combobox and handling its events.

    - by Wodzu
    Hi guys. I have a table in SQL Server which looks like this: ID Code Name Surname 1 MS Mike Smith 2 JD John Doe 3 UP Unknown Person and so on... Now I want to bind the data from this table into the ComboBox in a way that in the ComboBox I have displayed value from the Code column. I am doing the binding in this way: SqlDataAdapter sqlAdapter = new SqlDataAdapter("SELECT * FROM dbo.Users ORDER BY Code", MainConnection); sqlAdapter.Fill(dsUsers, "Users"); cbxUsers.DataSource = dsUsers.Tables["Users"]; cmUsers = (CurrencyManager)cbxUsers.BindingContext[dsUsers.Tables["Users"]]; cbxUsers.DisplayMember = "Code"; And this code seems to work. I can scroll through the list of Codes. Also I can start to write code by hand and ComboBox will autocomplete the code for me. However, I wanted to put a label at the top of the combobox to display Name and Surname of the currently selected user code. My line of though was like that: "So, I need to find an event which will fire up after the change of code in combobox and in that event I will get the current DataRow..." I was browsing through the events of combobox, tried many of them but without a success. For example: private void cbxUsers_SelectionChangeCommitted(object sender, EventArgs e) { if (cmUsers != null) { DataRowView drvCurrentRowView = (DataRowView)cmUsers.Current; DataRow drCurrentRow = drvCurrentRowView.Row; lblNameSurname.Text = Convert.ToString(drCurrentRow["Name"]) + " " + Convert.ToString(drCurrentRow["Surname"]); } } This give me a strange results. Firstly when I scroll via mouse scroll it doesn't return me the row wich I am expecting to obtain. For example on JD it shows me "Mike Smith", on MS it shows me "John Doe" and on UP it shows me "Mike Smith" again! The other problem is that when I start to type in ComboBox and press enter it doesn't trigger the event. However, everything works as expected when I bind data to lblNameSurname.Text in this way: lblNameSurname.DataBindings.Add("Text", dsusers.Tables["Users"], "Name"); The problem here is that I can bind only one column and I want to have two. I don't want to use two labels for it (one to display name and other to display surname). So, what is the solution to my problem? Also, I have one question related to the data selection in ComboBox. Now, when I type something in the combobox it allows me to type letters that are not existing in the list. For example, I start to type "J" and instead of finishing with "D" so I would have "JD", I type "Jsomerandomtexthere". Combobox will allow that but such item does not exists on the list. In other words, I want combobox to prevent user from typing code which is not on the list of codes. Thanks in advance for your time.
