• Gamma Distribution in Boost

  - by Kamchatka

  Hello, I'm trying to use the Gamma distribution from boost::math but it looks like it isn't possible to use it with boost::variate_generator. Could someone confirm that? Or is there a way to use it. I discovered that there is a boost::gamma_distribution undocumented that could probably be used too but it only allows to choose the alpha parameter from the distribution and not the beta. Thanks!

• Changing Name Associated With Past Commits In Mercurial

  - by Sean M

  A friend recently had the occasion for a legal name change, which made me wonder about how to cope with that in a development environment, especially in regards to source control. Their legal name changed, so naturally their login name and associated identity stuff changed. If they were a team member of mine, I'd like to change the record of their past commits to the project to be consistent with their new name. Is that possible in Mercurial? In other version control systems?

  - by frou

  In C#, is it possible to decorate an Enum type with an attribute or do something else to specify what the default value should be, without having the change the values? The numbers required might be set in stone for whatever reason, and it'd be handy to still have control over the default. enum Orientation { None = -1, North = 0, East = 1, South = 2, West = 3 } Orientation o; // Is 'North' by default.

  - by user1724421

  I'm having trouble figuring out a way to curry a function a specified number of times. That is, I give the function a natural number n and a function fun, and it curries the function n times. For example: (curry n fun) Is the function and a possible application would be: (((((curry 4 +) 1) 2) 3) 4) Which would produce 10. I'm really not sure how to implement it properly. Could someone please give me a hand? Thanks :)
