• What tool for printing Invoices and similar documents in Java Swing?

  - by Jonas

  I'm looking for a good tool for printing Invoices, Receipts and similar documents in Java Swing. I have tried JasperReports but it is pretty hard to get a dynamic layout and it is designing for reports. A requirement that I have is that the document should be sent directly to the printer and must not be saved to a file. So some tools that first creates an Office Document or a PDF document isn't a solution for me. Any recommendations?

• What is more correct class name or object name in UML sequence diagram?

  - by atch

  I was just wondering if it is more correctly to as a label of objects in UML sequence diagram instead of object name (which is irrelevant in my opinion and less informative than class name) provide class name. Another thing, while returning information instead of listing all objects names would it be a better solution to just write collection; Diagram with object names: Diagram with class names: As it's clearly visible from the second diagram that it is much more informative than the first one, and I think it is more practical.

  Hi, When I create a new Silverlight project in Visual Studio it creates a new web project in the same solution and wires it up to run in a local server when developing and debugging. Some demo projects I have downloaded just run directly from the test page on disk. When developing what are the benefits of running via a server? What would you lose by just running from the disk?

• Javascript (and HTML rendering) engine without a GUI for automation?

  - by MTsoul

  Are there any libraries or frameworks that provide the functionality of a browser, but do not need to actually render physically onto the screen? I want to automate navigation on web pages (Mechanize does this, for example), but I want the full browser experience, including Javascript. Thus, I'd like to have a virtual browser of some sort, that I can use to "click on links" programmatically, have DOM elements and JS scripts render within it, and manipulate these elements. Solution preferably in Python, but I can manage others.

• C# SQL: What is the best way to implement a dynamic table?

  - by SirMoreno

  I want to allow the user to add columns to a table in the UI. The UI: Columns Name:__ Columns Type: Number/String/Date My Question is how to build the SQL tables and C# objects so the implementation will be efficient and scalable. My thought is to build two SQL tables: TBL 1 - ColumnsDefinition: ColId, ColName, ColType[Text] TBL 2 - ColumnsValues: RowId, ColId, Value [Text] I want the solution to be efficient in DB space, and I want to allow the user to sort the dynamic columns. I work on .NET 3.5 MSSQL 2008. Thanks.

• Throwing cats out of windows

  - by AndrewF

  Imagine you're in a tall building with a cat. The cat can survive a fall out of a low story window, but will die if thrown from a high floor. How can you figure out the longest drop that the cat can survive, using the least number of attempts? Obviously, if you only have one cat, then you can only search linearly. First throw the cat from the first floor. If it survives, throw it from the second. Eventually, after being thrown from floor f, the cat will die. You then know that floor f-1 was the maximal safe floor. But what if you have more than one cat? You can now try some sort of logarithmic search. Let's say that the build has 100 floors and you have two identical cats. If you throw the first cat out of the 50th floor and it dies, then you only have to search 50 floors linearly. You can do even better if you choose a lower floor for your first attempt. Let's say that you choose to tackle the problem 20 floors at a time and that the first fatal floor is #50. In that case, your first cat will survive flights from floors 20 and 40 before dying from floor 60. You just have to check floors 41 through 49 individually. That's a total of 12 attempts, which is much better than the 50 you would need had you attempted to use binary elimination. In general, what's the best strategy and it's worst-case complexity for an n-storied building with 2 cats? What about for n floors and m cats? Assume that all cats are equivalent: they will all survive or die from a fall from a given window. Also, every attempt is independent: if a cat survives a fall, it is completely unharmed. This isn't homework, although I may have solved it for school assignment once. It's just a whimsical problem that popped into my head today and I don't remember the solution. Bonus points if anyone knows the name of this problem or of the solution algorithm.

• How to modify preorder tree traversal algorithm to handle nodes with multiple parents?

  - by poldo

  I've been searching for a while now and can't seem to find an alternative solution. I need the tree traversal algorithm in such a way that a node can have more than 1 parent, if it's possible (found a great article here: Storing Hierarchical Data in a Database). Are there any algorithms so that, starting from a root node, we can determine the sequence and dependencies of nodes (currently reading topological sorting)?

• How to get all the descendants of a given instance of a model in google app engine?

  Using parent child relationship where a parent can have children while each child has only one parent, does using Children.all().ancestor(parent.key) a good solution where a child is constructed by setting parent=parent.key in the constructor? Is the 1000 limit applies with this kind of query?
