  • Non blocking IO call from Django controller from a Windows service

    - by Anders
    Hi all, I have a CherryPy server with a Django application running as a Windows service, inside a controller I need to make a call to wmic, the problem is, so far I have only been able to implement a blocking operation. Does anyone have any recommendation for a non blocking operation so, at least more then one person at a time can access this controller and extract information from wmic? Thanks in advance, Anders

  • Static Typing and Writing a Simple Matrix Library

    - by duckworthd
    Aye it's been done a million times before, but damnit I want to do it again. I'm writing a simple Matrix Library for C++ with the intention of doing it right. I've come across something that's fairly obvious in mathematics, but not so obvious to a strongly typed system -- the fact that a 1x1 matrix is just a number. To avoid this, I started walking down the hairy path of matrices as a composition of vectors, but also stumbled upon the fact that two vectors multiplied together could either be a number or a dyad, depending on the orientation of the two. My question is, what is the right way to deal with this situation in a strongly typed language like C++ or Java?

  • Disable all non-clustered indexes

    - by spender
    I select a number of non-clustered indexes from my database with the following: SELECT sys.objects.name tableName, sys.indexes.name indexName FROM sys.indexes JOIN sys.objects ON sys.indexes.object_id = sys.objects.object_id WHERE sys.indexes.type_desc = 'NONCLUSTERED' AND sys.objects.type_desc = 'USER_TABLE' I'd like to run the following over each of the results: ALTER INDEX indexName ON tableName DISABLE How would I go about doing this? Is there a better way?

    - by Lost_in_code
    I'm writing all sorts of multi lingual text to .txt files using AIR's fileStream.writeUTFBytes() For english characters everything works perfectly. But as soon as there are chinese, arabic or any other non-english characters the sentences are totally messed up. For example: ???????????.... becomes ÂØpÁùħßÂèîÊëÑÂO±Â?àÁöÑÁ°ÆÊ=°Áà±.... How can this be fixed?

  • XSP2 crashes serving static images

    - by Dawkins
    Hi, Requesting a simple HTML page with a jpg image makes XSP2 crash. If I remove the image from the HTML then the page is served OK all the time. The version is XSP2 2.0 mono 2.6.1. the version 2.4.2.2 in the same machine works fine. I have tested it in two different machines, both Windows Vista Business SP1. Anyone has experienced the same? Any clue of what can be the problem? Below is the stack trace displayed by the console: (The line in Spanish says "it has been forced the interruption of an existing connection by the remote host") EDIT: since another user is having the same problem I have submited a bug to Novell and created a litle zip to reproduce the problem: https://bugzilla.novell.com/show_bug.cgi?id=582162 Peer unexpectedly closed the connection on write. Closing our end. System.IO.IOException: Write failure ---> System.Net.Sockets.SocketException: Se ha forzado la interrupción de una conexión existente por el host remoto. at System.Net.Sockets.Socket.Send (System.Byte[] buf, Int32 offset, Int32 size , SocketFlags flags) [0x00000] in <filename unknown>:0 at System.Net.Sockets.NetworkStream.Write (System.Byte[] buffer, Int32 offset, Int32 size) [0x00000] in <filename unknown>:0 --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Write (System.Byte[] buffer, Int32 offset, Int32 size) [0x00000] in <filename unknown>:0 at Mono.WebServer.XSPWorker.Write (System.Byte[] buffer, Int32 position, Int32 size) [0x00000] in <filename unknown>:0 Peer unexpectedly closed the connection on write.

  • controlling if exceptions are swallowed by a static boolean

    - by sandis
    So we are a few guys developing this product that is communicating with a really unstable server. It often returns very strange and corrupt data. During testing we want the resulting crashes to be loud, so we discover them. But every other day we need to demonstrate our product for a potential customer. To the customer the errors will go undiscovered if we just swallow them. I am thinking about implementing something like this around all server communication to quickly switch between swallowing exceptions and crashing: try { apiCall(); } catch (Exception e) { if(!SWALLOW_EXCEPTION) { throw e; } } Is this an awesome idea, or can it be done in a better way?

  • Type-safe, generic, empty Collections with static generics

    - by Droo
    I return empty collections vs. null whenever possible. I switch between two methods for doing so using java.util.Collections: return Collections.EMPTY_LIST; return Collections.emptyList(); where emptyList() is supposed to be type-safe. But I recently discovered: return Collections.<ComplexObject> emptyList(); return Collections.<ComplexObject> singletonList(new ComplexObject()); etc. I see this method in Eclipse Package Explorer: <clinit> () : void but I don't see how this is done in the source code (1.5). How is this magic tomfoolerie happening!!

  • How to create a static header that remains even when navigating to other pages (lala.com)

    - by user169867
    I'm interested in the way lala.com works. They have a header that remains fixed at the top of the browser and they have a flash music player in it. You can click on other links in the site and they are displayed below the header but the header is not disrupted and can continue playing music. If the target is a modern browser say IE8 & FF 3.6, what's the best way to achieve this? Thanks for any help.

  • Load WPF styles (static resources) from an external assembly

    - by Shimmy
    I have a few WPF applications and I want all my styles to be in a shared assembly instead of declaring them in each application separately. I am looking for a way so I don't have to change all my Style="{StaticResource BlahBlah}" in the existing applications; I just want to add the reference to this style assembly, and delete it from the current application, so it's taken from the assembly. Is there any way?

  • Combine static files or load in parallel

    - by Niall Collins
    I am at present introducing code to my site to combine css and javascript files. Is there a way without having to include an external library to load javascript asynchronously or in parallel? I have read on some blogs that combining of files can be counter productive as the load of the http request can be large and its better to load multiple files in parallel. Opinions on this? I am caching my javascript/css. And would have thought it was better to combine rather than have multiple http requests.

  • UICollectionView with one static cell and N dynamic ones from a fetchresultscontroller exception

    - by nflacco
    I'm trying to make a UITableView that shows a blog post and comments for that post. My setup is a tableview in storyboard with two dynamic prototype cells. The first cell is for the post and should never change. The second cell represents the 0 to N comments. My cellForRowAtIndexPath method shows the post cell properly, but fails to get the comment at the given index path (though if I comment out the fetch I get the appropriate number of comment cells with a green background that I set as a visual debug thing). let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment I get the following exception on this line: 2014-08-24 15:06:40.712 MessagePosting[21767:3266409] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 1 beyond bounds [0 .. 0]' *** First throw call stack: ( 0 CoreFoundation 0x0000000101aa43e5 __exceptionPreprocess + 165 1 libobjc.A.dylib 0x00000001037f9967 objc_exception_throw + 45 2 CoreFoundation 0x000000010198f4c3 -[__NSArrayM objectAtIndex:] + 227 3 CoreData 0x00000001016e4792 -[NSFetchedResultsController objectAtIndexPath:] + 162 Section and cell setup: override func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int { // #warning Incomplete method implementation. // Return the number of rows in the section. switch section { case 0: return 1 default: if let realPost:Post = post { return fetchedResultController.sections[0].numberOfObjects } else { return 0 } } } override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! { switch indexPath.section { case 0: let cell = tableView.dequeueReusableCellWithIdentifier(postViewCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = lightGrey if let realPost:Post = self.post { cell.textLabel.text = realPost.text } return cell default: let cell = tableView.dequeueReusableCellWithIdentifier(commentCellIdentifier, forIndexPath: indexPath) as UITableViewCell cell.backgroundColor = UIColor.greenColor() let comment = fetchedResultController.objectAtIndexPath(indexPath) as Comment // <---------------------------- :( cell.textLabel.text = comment.text return cell } } FRC: func controllerDidChangeContent(controller: NSFetchedResultsController!) { tableView.reloadData() } func getFetchedResultController() -> NSFetchedResultsController { fetchedResultController = NSFetchedResultsController(fetchRequest: taskFetchRequest(), managedObjectContext: managedObjectContext, sectionNameKeyPath: nil, cacheName: nil) return fetchedResultController } func taskFetchRequest() -> NSFetchRequest { if let realPost:Post = self.post { let fetchRequest = NSFetchRequest(entityName: "Comment") let sortDescriptor = NSSortDescriptor(key: "date", ascending: false) fetchRequest.predicate = NSPredicate(format: "post = %@", realPost) fetchRequest.sortDescriptors = [sortDescriptor] return fetchRequest } else { return NSFetchRequest(entityName: "") } }

  • Preference values - static without tables using a model with virtual attributes

    - by Mike
    Im trying to eliminate two tables from my database. The tables are message_sort_options and per_page_options. These tables basically just have 5 records which are options a user can set as their preference in a preferences table. The preferences table has columns like sort_preferences and per_page_preference which both point to a record in the other two tables containing the options. How can i set up the models with virtual attributes and fixed values for the options - eliminating table lookups every time the preferences are looked up?

  • Streaming video using non standard protocols

    - by Dan
    Hi - My company makes DVRs that specialize in streaming live and recorded video. The video is encoded using standard MPEG-4 codecs so the codecs in Android should have no trouble with them. However, the video is recorded using non-standard file formats and is streamed using our proprietary protocol (among other things we embed additional data such as watermarks with each frame of video). Is there any way I can take my stream pull out the frames and have it play on an Android device? Thanks!

  • Association not imported in EF4 designer for non-primary key

    - by Rommel Manalo
    The relationship 'FK_EXTERNAL_ISMARKETI_MARKETIN' has columns that are not part of the key of the table on the primary side of the relationship. The relationship was excluded.
