• Ruby 1.9 and Rackspace's email api (SOAP)

  - by kjs3

  Is anyone out there working with SOAP on Ruby 1.9? Rackspace has email addresses for $2/month and an api to programmatically create/destroy accounts which looks like the best I've found. Fusemail has $2 addresses too but you need a minimum of 80 to get access to the api. So, I either need to find a solution to working with Rackspace or a different email host.

• which of these modes : cbc,cfb,ctr,ecb,ncfb,nofb,ofb,stream are secure and which are absolute no-no

  - by user393087

  By security I mean that encoded string is indistinguishable from random noise and is different on every encryption of the same text so it is impossible to make a guess on encryption algorithm used or do any dictionary attack on the encoded text. Second: output string length does not correspond to the input string length in easy way, so it is not possible of make guessing on that account. Third: it is possible to verify that the provided password is incorrect so the decoding function could return false instead of supposedly decoded random string.

• Does EGit mandate installing JGit?

  - by Souper

  After using Git from the command line for a while, I am ready for the convenience a GUI plugin (for Eclipse) can offer. However, I prefer a Git plugin similar to to MS Visual Studio's Git Source Control Provider which is only a wrapper around the already installed msysgit. I really don't want two different Git implementations accessing the same repository. EGit sounds perfect - if it can use the already installed msysgit in my PC. But can it?

  - by wvd

  Hello all, I'm doing some small projects which involve having different syntaxis for something, however sometimes these syntaxis are so easy that using a parser generator might be overkill.

• Problem with user login validation by authlogic

  - by Andrei

  Hi, I want to use email for signing in, and to allow users to have similar names. One way to do this is to rename login/username field to something different. However, I want to do it just by setting up authlogic. I tried the following acts_as_authentic do |c| c.login_field :email c.validate_login_field false c.validate_email_field true end but it still complains that the login already exists. What must be done to avoid username validation without renaming the field?

• C#, Windows Services: ServiceBase.Run with several services of the same type

  - by Austin Salonen

  I'm trying to run several similar services via ServiceBase.Run(ServiceBase[] ) but it's only running the first one. MSDN doesn't explicitly deny this; does this excerpt mean that they all must be different types? (the bold is by me, not MSDN) Call this overload in the main() function of the service executable to load an array of associated services.

I have in mind a "Windows Explorer"-like application where a user can right click on a folder and get a list of menu items but right click on a drive and get a totally different list. What design pattern should I use ? Would the factory design pattern be appropiate for handling such a menu ? Regards, Seb
