• Scala for Junior Programmers?

  - by Traldin

  Hi, we are considering Scala for a new Project within our company. We have some Junior Programmers with only PHP knowledge, and we are in doubt that they can handle Scala. What are your opinions?

• ConfigurationManager.OpenExeConfiguration() vs XML file

  - by Vince

  Hi, Could someone tell me the advantages to using the ConfigurationManager class which load's a config file for manipulation VS an XML file with a class you build to read it yourself? Recently, I built a class which inherits from ConfigurationSection in order to manipulate a custom section within app.config. This was quite a bit of work compared to just opening and reading an XML file. Some people chose the first approach, others chose the second. What's good practice?

• What predefined macro can I use to detect clang ?

  - by Pierre Bourdon

  I'm trying to detect the compiler used to compile my source code. I can easily find predefined macros to check for MSVC or GCC (see http://predef.sourceforge.net/ for example), but I cannot find any macro to check for clang. Does someone know if clang defines a macro like __CLANG__ in order to know what is currently compiling my code ?

  Apparently .NET 4.0 does not have the PartCreator/ExportFactory for non-SL. Which is something I think I need for this. I was wondering if someone can help me (with an example please) of how to create multiple instances of the EXPORTED type in a DLL. Basically say I have a DLL that contains a type ConsoleLogger and it uses the interface ILogger (which I import/export through MEF)...How would I create an instance of ConsoleLogger whenever I wanted to? Also..Is this even possible?

• Why are IOC containers unnecessary with dynamic languages

  - by mikemay

  Someone on the Herding Code podcast No. 68, http://herdingcode.com/?p=231, stated that IOC containers had no place with Python or Javascript, or words to that effect. I'm assuming this is conventional wisdom and that it applies to all dynamic languages. Why? What is it about dynamic languages that makes IOC containers unnecessary?

• Float PPM image file format?

  - by Luca

  I've found a PPM image with the header starting with PF. The resolution number is stored in floating point (-1.000). No comments are inserted to get how it was produced. From the resolution, each pixel is composed by 12 bytes (4 bytes per component)... I suppose they are float or integer numbers. The problem is that I cannot get a clear image. Someone has already found this kind of images?

• singleton vs factory?

  - by fayer

  i've got 3 Log classes that all implements iLog interface: DatabaseLog FileLog ScreenLog there can only be one instance of them. initially i though of using single pattern for each class but then i thought why not use a factory for instantiation instead, cause then i wont have to create single pattern for each one of them and for all future Log classes. and maybe someone would want them as multiple objects in the future. so my questions is: should i use factory or singleton pattern here?
