• Besides DI, what benefits can I get from an IoC container?

  - by MOZILLA

  IoC Frameworks just make DI much easier, but it's not only DI that they do, they provide a host of other benefits over and above DI. I saw this comment in one of the answers to a question about DI and IoC. Can someone explain this in some more details? What are other benefits of IoC?

• Selecting favourites from DB rails 3

  - by Richlewis

  I have a small app which has Users, Recipes, Ingredients and preparation models A user has many recipes, recipes belong to user and ingredients/preparation belongs to recipes. Now a user can view all recipes but I would like the option to add the particular recipe to a favourites list. Would I need to set a new DB to hold this and then link by associations or could I add a column to the recipe model called fav for example? Im looking for the best practice here or if someone has done this before and can offer any advice that would be appreciated

• Need a scenario where would fail Array.ConstrainedCopy()

  - by Sir Psycho

  Hi, Just playing around with some of the APIs in .NET and I can't seem to find a way to cause Array.ConstrainedCopy() fail. According to MSDN, it's treated as an atomic operation. If it fails during the copy, the entire call fails resulting in no elements being copied as opposed to its Array.Copy() counterpart. Can someone demonstrate this or tell me how to do this?

Something similar to the email sending by exception notifier when there is an error in Rails app. I wonder because now we have no way to find out if someone hits an unexpected app spawner or other error (like memory limit etc.).

• x86 Instruction Format: "ba 0e 00 00 00" ... "mov $0xe,%edx"

  - by Andrew Tomazos - Fathomling

  I'm getting the following line in the disassembly from objdump -d of an x86 linux program... 4000b0: ba 0e 00 00 00 mov $0xe,%edx I'm trying to understand how the machine code "ba 0e 00 00 00" maps to "mov $0xe,%edx" In the manual move immediate 32-bit is: B8 + rd ... MOV r32, imm32 ie "B8" not "BA" In fact none of the MOV opcodes are "BA". If someone could break down "ba 0e 00 00 00" and explain bit-wise how to get to "mov $0xe,%edx" it would be most helpful.
