• Fast or asynchronous AS3 JPEG encoding

  - by Bart van Heukelom

  I'm currently using the JPGEncoder from the AS3 core lib to encode a bitmap to JPEG var enc:JPGEncoder = new JPGEncoder(90); var jpg:ByteArray = enc.encode(bitmap); Because the bitmap is rather large (3000 x 2000) the encoding takes a long while (about 20 seconds), causing the application to seemingly freeze while encoding. To solve this, I need either: An asynchronous encoder so I can keep updating the screen (with a progress bar or something) while encoding An alternative encoder which is simply faster Is either possible?

• Django - Better evaluation of relationship at the model level

  - by Brant

  Here's a simple relational pair of models. class Shelf(models.Model): name = models.CharField(max_length=100) def has_books(self): if Book.objects.filter(shelf=self): return True else: return False class Book(models.Model): shelf = models.ForeignKey(Shelf) name = models.CharField(max_length=100) Is there a better (or alternative) way to write the "has_book" method? I'm not a fan of the double database hit but I want to do this at the model level.

• log analysis for rails

  - by deepak

  i have a rails app which makes heavy use of activeresource and httparty to make api calls. Is there any library/extension to log the requests and parse them, so that log analysis becomes easier and automated. RailsLogAnalyser is good but what about extra calls, what are the conventions? Something like a opensource/self-hosted alternative to newrelic, but with extensions to plug in your own logging.

• CHECK/NOCHECK for Sql Compact Edition

  - by Ryan H

  I am attempting to wipe and repopulate test data on SQL CE. I am getting an error due to FK constraints existing. Typically in Sql2005 I would ALTER TABLE [tablename] CHECK/NOCHECK CONSTRAINT ALL to enable/disable all constraints. From what I could find in my searching, it seems that this might not be supported in CE. Is that true? If so, is there an alternative?

• What's the most minimal way to achieve Dependency Injection?

  - by Chuck

  I've been reading about Spring and although it's claimed to be a less complex alternative to EJB, I'm having a hard time wrapping my head around it. Is there a more minimal way of achieving Dependency Injection than adopting the Spring approach?

• Algorithm for Negating Sentences

  - by Kevin Dolan

  I was wondering if anyone was familiar with any attempts at algorithmic sentence negation. For example, given a sentence like "This book is good" provide any number of alternative sentences meaning the opposite like "This book is not good" or even "This book is bad". Obviously, accomplishing this with a high degree of accuracy would probably be beyond the scope of current NLP, but I'm sure there has been some work on the subject. If anybody knows of any work, care to point me to some papers?

• Keeping track of changes - Django

  - by RadiantHex

  Hi folks!! I have various models of which I would like to keep track and collect statistical data. The problem is how to store the changes throughout time. I thought of various alternative: Storing a log in a TextField, open it and update it every time the model is saved. Alternatively pickle a list and store it in a TextField. Save logs on hard drive. What are your suggestions?

  - by number5

  I'm trying to learn some Smalltalk. Fisrt found was Squeak, but since it has been removed from Gentoo ebuild tree because of security problem, so I decided to find an alternative. Then I found Pharo through Seaside project, after I downloaded Pharo 1.0 package, there are actually a SqueakVM inside! So, my question is: Is Pharo just a repackaging/rebranding of Squeak? And are those security problem of Squeak (bundle unsecure libs) still applied to Pharo? Thanks!

• Which View Engine are you using with ASP.NET MVC?, and Why?

  - by Sosh

  Hi, I'm thinking of experimenting with alternative View Engines for ASP.NET MVC, and would like to know what other people are using. Please let me know 1) Which View Engine you use, and 2) Why. The standard 'web-forms' view engine is of course a valid answer, but please say so only if you have decided to use it for a reason, not just 'Becuase I can't be bothered to change it' ;) Thank you!

• What's the nearest substitute for a function pointer in Java?

  - by Bill the Lizard

  I have a method that's about 10 lines of code. I want to create more methods that do the exact same thing except for a calculation that's going to change one line of code. This is a perfect application for passing in a function pointer to replace that one line, but Java doesn't have function pointers. What's my best alternative?

  In our development we use two servers with PostgreSQL 8.4 - development and production. So, after changes were made on development server we would like to automatically generate SQL migration scripts.

• Is DxScene the "WPF for Delphi"? Anyone used it?

  - by André Mussche

  I am playing with DxScene and VxScene: http://www.ksdev.com/dxscene/index.html It looks very nice and powerful: 3d accelerated vector graphics, cross plaform, nice effects, many 2d GUI controls (vector based), good scaling, transparency, rotating (x, y, z), 3d models, etc. Even with many effects, the CPU stays very low (0%)! http://www.ksdev.com/dxscene/snapshot/screen0.jpeg But can it be seen as a good WPF alternative for Delphi? And does anyone use it instead of normal Delphi VCL?

• Having a Backgroundworker refresh splash screen

  - by Jiri

  Hi, Would it be theoretically possible to make BackgroundWorker in a class to periodically refresh existing splash screen form, or is that impossible? (I know that it's probably bad design, but currently I do not see any better way.) Please keep in mind that: I do not want the background worker to do the loading as it would be terribly hard to implement. I can't use the inbuilt splash screen support I'm aware of DoEvents alternative but I do not want to go this path, it would very hard to implement as well, and not reliable.

• Jquery Effect Onunload

  - by j3frea

  I would like to use the jquery slideUp effect when the user navigates away from the page just to make the page look cool as it closes. I assume that I should use the onunload event but how can I delay the page closing long enough for the effect to run to completion. One of the options that came to mind is effectively hijacking the page closing function, storing it in some variable and then executing it once I had run my effect but I have no idea how I would do that. Any suggestions or alternative ideas are more than welcome

  I'm looking for an implementation preferably in Java of an algorithm for finding a Minimum Equivalent Graph of a Digraph (http://portal.acm.org/citation.cfm?id=321526.321534).
