• What is the most difficult type of software to write?

  - by Austin

  This question just really interested me, so I got curious to know what the community thinks. What do you guys think is the most difficult type of software to write? I write government software and have found it's pretty hair-pulling, but I'm sure there are far worse things out there.

Hopefully simple question: I have multiply nested namespace: namespace first {namespace second {namespace third { // emacs indents three times // I want to intend here } } } so emacs indents to the third position.

• Rails 2.3.2: Accessing Model Specific Data in Another Model

  - by Gimli

  I'm using Rails 2.3.2 and using Paperclip to upload photos. I'm also using a slightly customized subdomain_accounts.rb to set some account-specific variables. My question is this: How can I set the bucket used in Paperclip to be dependent on the current account? Since this looks to be a model attribute set up early on, how can I override it later? Thanks.

• What size paper or white board do you use for brainstorming / planning ?

  - by Naveen

  Use a small notepad, and turning pages interferes with flow of thought. Use a whiteboard and marker, and you write bigger when you are standing up, so you don't necessarily get more ideas on the board... A friend of mine has his entire wall in his office, lab made up of whiteboard material... This is a more specific question on a related topic.

• .Net 4.0 Memory-Mapped Files verses RDMS Storage

  - by Harry

  I'm interested in people's thoughts comparing storing data in a traditional SQL based Database or utilising a Memory-Mapped File such as the one in the new .Net 4.0 runtime. The data in question would be arrays of simple structures. Obvious pros and cons: SQL Database Pros Adhoc query support SQL Management Tools Schema changes (adding more columns and setting default values) Memory-Mapped Pros Lighter overhead? (this is an assumption on my part) Shareable between process threads Any others? Is it worth it for performance gains?

• Working with utf-8 files in Eclipse.

  - by Pablo Cabrera

  Quite straight forward question. Is there a way to configure Eclipse to work with text files encoded with utf-8 with and without the BOM? So far I've used eclipse with utf-8 encoding and it works, but when I try to edit a file generated by another editor that includes the BOM, Eclipse doesn't handle it properly, it 'shows an invisible character' at the begining of the file (the BOM). Is there a way to make Eclipse understand utf-8 encoded files with BOM?

• Visual Basic 9 with Visual Studio 2010

  - by jaraics

  I'm working on a project started in VB9 (VS 2008) and now I've migrated to VS2010 (VB10) but on the production server the IDE is still VS 2008. On my developement enviroment the code compiles fine, but sometimes, - let's say - I forget an _ at the end of the line which causes the VB9 compiler to throw an error. So the question is, how could I build a project with the VS 2010 IDE but VB9 compiler? Or to force the VB10 compiler into VB9 mode?

• cocoa -- What is the proper way to tell an NSWindow to redisplay its contents?

  - by William Jockusch

  According to the NSWindow Class Reference, you should "rarely need to invoke" the NSWindow methods "display" or "setViewsNeedDisplay". So what is the usual way to redisplay the window's contents? EDIT: I am having trouble dealing with resizing events. I just want to have everything scale proportionally. See this question. As no one seems to have any ideas for using masks to get it to happen, I want to redraw the whole thing.
