  • Applications for the Church Programming Language

    - by Chris S
    Has anyone worked with the programming language Church? Can anyone recommend practical applications? I just discovered it, and while it sounds like it addresses some long-standing problems in AI and machine-learning, I'm sceptical. I had never heard of it, and was surprised to find it's actually been around for a few years, having been announced in the paper Church: a language for generative models.

  • How can I find out if an instance is a MarshalByRef proxy?

    - by Will
    I know there's a way, I know I've done it (a long time) before, but I can't remember or find out how to do it!!! var otherDomain = AppDomain.Create("Lol my memory sucks"); var myRemotableType = typeof(MyTypeThatExtendsMBRO); var proxy = otherDomain .CreateInstanceAndUnwrap( type.Assembly.FullName, type.FullName); // how do you do this next step??? bool isProxy = IsYouIsOrIsYouAintAProxy(proxy);

  • File upload progress

    - by Cornelius
    I've been trying to track the progress of a file upload but keep on ending up at dead ends (uploading from a C# application not a webpage). I tried using the WebClient as such: class Program { static volatile bool busy = true; static void Main(string[] args) { WebClient client = new WebClient(); // Add some custom header information client.Credentials = new NetworkCredential("username", "password"); client.UploadProgressChanged += client_UploadProgressChanged; client.UploadFileCompleted += client_UploadFileCompleted; client.UploadFileAsync(new Uri("http://uploaduri/"), "filename"); while (busy) { Thread.Sleep(100); } Console.WriteLine("Done: press enter to exit"); Console.ReadLine(); } static void client_UploadFileCompleted(object sender, UploadFileCompletedEventArgs e) { busy = false; } static void client_UploadProgressChanged(object sender, UploadProgressChangedEventArgs e) { Console.WriteLine("Completed {0} of {1} bytes", e.BytesSent, e.TotalBytesToSend); } } The file does upload and progress is printed out but the progress is much faster than the actual upload and when uploading a large file the progress will reach the maximum within a few seconds but the actual upload takes a few minutes (it is not just waiting on a response, all the data have not yet arrived at the server). So I tried using HttpWebRequest to stream the data instead (I know this is not the exact equivalent of a file upload as it does not produce multipart/form-data content but it does serve to illustrate my problem). I set AllowWriteStreamBuffering to false and set the ContentLength as suggested by this question/answer: class Program { static void Main(string[] args) { FileInfo fileInfo = new FileInfo(args[0]); HttpWebRequest client = (HttpWebRequest)WebRequest.Create(new Uri("http://uploadUri/")); // Add some custom header info client.Credentials = new NetworkCredential("username", "password"); client.AllowWriteStreamBuffering = false; client.ContentLength = fileInfo.Length; client.Method = "POST"; long fileSize = fileInfo.Length; using (FileStream stream = fileInfo.OpenRead()) { using (Stream uploadStream = client.GetRequestStream()) { long totalWritten = 0; byte[] buffer = new byte[3000]; int bytesRead = 0; while ((bytesRead = stream.Read(buffer, 0, buffer.Length)) > 0) { uploadStream.Write(buffer, 0, bytesRead); uploadStream.Flush(); Console.WriteLine("{0} of {1} written", totalWritten += bytesRead, fileSize); } } } Console.WriteLine("Done: press enter to exit"); Console.ReadLine(); } } The request does not start until the entire file have been written to the stream and already shows full progress at the time it starts (I'm using fiddler to verify this). I also tried setting SendChunked to true (with and without setting the ContentLength as well). It seems like the data still gets cached before being sent over the network. Is there something wrong with one of these approaches or is there perhaps another way I can track the progress of file uploads from a windows application?

  • creating an executable file without a compiler

    - by Alterlife
    I came across an article a long while ago on how to write out a .com file directly without using any external tools. the method was to basically copy con myfile.com and then hit ctrl+alt+number for each instruction. I've lost the url for the guide... Google isn't helping much either. If you have the link, please could you post it.

  • WYSIWYG editor for Windows forms

    - by Tired
    Does anyone know of a good WYSIWYG editor for Windows forms. If I use a rich textbox, I need to handle pasting events, bold buttons, fonts etc, which is a nightmare. I’m currently using the HTML control, suggested by many sites, but I have a large form, with many tabs. Since I have to load up to 8 HTML controls, loading the form takes too long. Any help?

  • Catching a python app before it exits

    - by Leopd
    I have a python app which is supposed to be very long-lived, but sometimes the process just disappears and I don't know why. Nothing gets logged when this happens, so I'm at a bit of a loss. Is there some way in code I can hook in to an exit event, or some other way to get some of my code to run just before the process quits? I'd like to log the state of memory structures to better understand what's going on.

  • Gathering Staff anyone interested?

    - by kasene
    Thread Title - Gathering Staff Rush-Soft Game Design is currently looking for staff of a moderate skill level. Team Name - RushSoft Game Design Project Name - N/A We are gathering staff so that we can begin working on a new game. Target Aim - Freeware / Free Version - Paid Version With our first project our aim is to simply get our name out there. Generally we will be targeting a freeware distribution platform or a Free and Paid version. Compensation - Prehaps in the future but don't rely on it If in the future we start developing a game we intend to make any sort of sizable profit from then yes, there will be compensation however currently our low, low funding comes from generous donations. Any money that we make for now will go to the teams funding for things like engine licenses and company registration. Technology - C/C++ RSETech Our primary functional language will be C/C++ as most games are. We will be using a custom built library built on Direct3D called RSETech or RushSoft Engine Technology. Currently its is fully capable of being used for developing a game. The final version is made up of almost entirely C (No C++ or OOP). There is a C++ version currently in the works. Programming: - Microsoft Visual C++ 2008 / 2010 2D Art - Photoshop CS2 - GIMP Talent Needed - We currently are in need of x2 Programmers - With understanding of the following C/C ++ and game programming aspects: -If/Else Conditions -Functions/Methods -Arrays -Pointers (You don't need to fully understand these. Just know when they need to be used.) -Enums -Loops (For and While) -Structs (and How to use . and - syntax) -Classes (and how to call methods and access variables from a class) -State Machines -Switches -Include Guards -Understanding of how game loops work in general. (Init, Update, Render, Deinit) x2 Artists - As long as you have the means to and are able to draw 2D sprites and collab with a game designer to get a good result. 1 or more Game Designers - You can design levels (for platformers) as well as write game scripts and you can come up with good ideas and game mechanics. As long as you can do these things and are able to work well with artists and programmers you're golden. Business Consultant - Someone who knows the industry and how it works. Will inquire about possible distribution platforms as well as contact other developers, websites, and publishers on RushSofts behalf.

  • Facebook dialogs keep popping up in Firefox

    - by Pierre Olivier Martel
    I have a facebook application running in a FBML canvas and I have a problem with dialogs (either extended permissions or stream publish dialogs). Once they popup, they keep popping up for every subsequent requests. I've tested it in Chrome and everything works fine. It seems that the URL is chained in Firefox, which gives cryptic long urls like : http://apps.facebook.com/webdweller-po/discover?_fb_q=1&_fb_qsub=apps.facebook.com#!/webdweller-dev/?_fb_q=1&_fb_qsub=apps.facebook.com Did anybody experienced such a bug?

  • django: caching passwords for custom authentication

    - by gruszczy
    I am authenticating users in ldap, but this happens only once, when user is logging in. Afterwards I need to keep username and password, because before every ldap operation I need to make bind on ldap server before every operation. What is the safe way to cache this password (I can't store in the database or cookies) for as long as session persists.

  • org.hibernate.TransientObjectException during Criteria.list()

    - by rancidfishbreath
    I have seen posts all over the internet that talk about how to fix the TransientObjectExceptions during save/update/delete but I am having this problem when calling list on my Criteria. I have two objects A and B. A has a field named b which is of type B. In my mapping b is mapped as a many-to-one. This all runs in a larger persistence framework (the framework is kind of like Core Data) and so I don't use any cascades in my hibernate mappings since cascades are handled at a higher level. This is the interesting code surrounding my criteria: A a = new A(); B b = new B(); a.setB(b); session.save("B", b); // Actually handled by the higher level session.save("A", a); // framework, this is just for clarity // transaction committed and session closed ... // new session opened Criteria criteria = session.createCriteria(A.class); criteria.add(Restrictions.eq("b", b)); List<?> objects = criteria.list(); Basically I am looking for all objects of type A such that A.b equals a particular instance of b (I actually tried restructuring a query so that I was passing in the id of b just to make sure that b wasn't causing me problems). Here is the stack trace that occurs when I call criteria.list(): org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: B at org.hibernate.engine.ForeignKeys.getEntityIdentifierIfNotUnsaved(ForeignKeys.java:244) at org.hibernate.type.EntityType.getIdentifier(EntityType.java:449) at org.hibernate.type.ManyToOneType.nullSafeSet(ManyToOneType.java:141) at org.hibernate.loader.Loader.bindPositionalParameters(Loader.java:1769) at org.hibernate.loader.Loader.bindParameterValues(Loader.java:1740) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1612) at org.hibernate.loader.Loader.doQuery(Loader.java:717) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:270) at org.hibernate.loader.Loader.doList(Loader.java:2294) at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2172) at org.hibernate.loader.Loader.list(Loader.java:2167) at org.hibernate.loader.criteria.CriteriaLoader.list(CriteriaLoader.java:119) at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1706) at org.hibernate.impl.CriteriaImpl.list(CriteriaImpl.java:347) Here is my mapping: <class entity-name="A" lazy="false"> <tuplizer entity-mode="dynamic-map" class="MyTuplizer" /> <id type="long" column="id"> <generator class="native" /> </id> <many-to-one name="b" entity-name="B" column="b_id" lazy="false" /> </class> <class entity-name="B" lazy="false"> <tuplizer entity-mode="dynamic-map" class="MyTuplizer" /> <id type="long" column="id"> <generator class="native" /> </id> </class> Can anyone help me figure out why I would be getting a TransientObjectException during a fetch? Preferably I would like to find a solution that does not rely on cascades since they tend to mask problems that occur in the higher level framework.

EDIT: removed "(no accepted answer)" from title. it was misleading.

  • How to detect that an Html element is in View?

    - by Olaseni
    Using Jquery preferably, how do I detect if an element is within the viewable client area of a browser? I'm dynamically creating a menu from a dataset, and when the list grows too long, the height of the resulting menu causes part of it to fall below the browser bottom client area. How do I detect this and act accordingly?

  • How to output LogCat to Console?

    - by Shooshpanchick
    Is there a way to make LogCat's output to appear in Console view in Eclipse? LogCat view is much less convenient that Console, because it's hard to see long messages in it (they are trimmed by column border) and there are no clickable highlighting in exception stack traces to quickly navigate to source of error.

  • Execution time of ALTER COLUMN

    - by Tommy Jakobsen
    Having a table with 60 columns, and 200 rows. Altering a BIT column from NULL to NOT NULL, now has a running execution time of over 3 hours. Why is this taking so long? This is the query that I'm execution: ALTER TABLE tbl ALTER COLUMN col BIT NOT NULL Is there a faster way to do it, besides creating a new column, updating it with values from the old column, then dropping the old column and renaming the new one? This is on MS SQL Server 2005.
