• How to organize makefiles / solutions etc. in multiplatform projects?

  - by Michal Czardybon

  I have a project which can be compiled with Visual Studio, GCC and with some embedded compilers. Sources are shared, but each platform requires separate makefiles, project files, solutions etc. There are two ways I can organize them: Intermixed in a single hierarchy of folders With separate folders for platform-dependent files The first solution creates some confusion about which file belongs to which platform, but the second causes some repetition of the folders structure (some compilers require each project to have a separate folder). Which do you think is better?

• Python 3 with numpy and object refernces

  - by user963386

  I need to create a large matrix (array) structure (3 axis) and each element should store the reference to a Python object (myclass instance). Is it possible to use numpy to create such an array. Which data type should I use in order to store Python references? The advantage of numpy is the support of slicing at different levels. The alternativee is to create a nested (nested) list but it is a cumbersome solution.

• does the object creating a sub appdomain get instantiated in that sub appdomain?

  - by Eric

  does the object creating a sub appdomain get instantiated in that sub appdomain? I have an object that is in the main AppDomain and it is creating another AppDomain and it requires the calling class to be serializable and is creating an instance of the calling class in the new sub AppDomain. I'm wondering if that is how it is, or if there is a way that I can create the sub appDomain but still hold on to the original instantiation of the calling object in the main appDomain

• Do non-clustered indexes slow down inserts?

  - by mikeinmadison

  I'm working in Sql Server 2005. I have an event log table that tracks user actions, and I want to make sure that inserts into the table are as fast as possible. Currently the table doesn't have any indexes. Does adding a single non-clustered index slow down inserts at all? Or is it only clustered indexes that slow down inserts? Or should I just add a clustered index and not worry about it?

• How can I compose a WCF contract out of multiple interfaces?

  - by mafutrct

  I've got multiple interfaces. All of them should be inherited and exposed by a single contract interface. interface A { void X(); } interface B { void Y(); } interface C: A, B {} // this is the public contract How is this possible? I can't add ServiceContract to A and B because that would lead to multiple endpoints. And I don't want to new-override every method in C.

• Are there any modeling tools that can visually generate jpa or sql queries?

  - by Shervin

  Does anyone know of a tool like PowerArchitect or SquirrelSQL or maybe eclipse plugin that lets you also generate jpa/sql queries? Imagine you choosing your database, or your entity beans, and the modeling would reverse engineer your database/entity model, so that you could visually just choose the columns you wanted to select, and it would generate jpa or sql queries for you. For instance choosing A.b and X.y would generate something like this: select a.b, x.y from A a, X x join ......

• Base 62 conversion in Python

  - by mikl

  How would you convert an integer to base 62 (like hexadecimal, but with these digits: '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ'). I have been trying to find a good Python library for it, but they all seems to be occupied with converting strings. The Python base64 module only accepts strings and turns a single digit into four characters. I was looking for something akin to what URL shorteners use.

• Construct a Netflix Affiliate URL to a search result page?

  - by Felix

  I have a Netflix Affiliate account, but I don't want to direct users to the homepage for them to create an account, I want to direct them to a search result page. The reason for this is that on our site we have lots of titles but they can't be reliably linked to a single Netflix result programmatically, so we would prefer if we could direct users to a search page, and if the user signs up, get the revenue. Is this possible? I find the whole Netflix-Affiliate-but-Google-Affiliate scheme a bit daunting.

• Dynamically creating objects at runtime that inherit from a base class

  - by Homeliss

  I am writing a game editor, and have a lot of different "tool" objects. They all inherit from BTool and have the same constructor. I would like to dynamically populate a toolbox at runtime with buttons that correspond to these tools, and when clicked have them create an instance of that tool and set it as the current tool. Is this possible, and if so will it be better/easier than creating those buttons by hand?
