the osi today announced the approval of two microsoft open source licenses, the Ms-PL (Microsoft Public License) and the Ms-RL (Microsoft Reciprocal License).  the osi process is one that is in the open and allowed microsoft and open source communities to discuss the nature of the licenses in an open forum.  as a result of that process, the licenses (after being renamed to the above) were approved.  the licenses were submitted to the osi on 10 aug 2007.

this means that ironruby is officially an open source project :-)

UPDATE: you may have noticed the "public license" -- no that isn't a typo.  this is what the community process suggested the permissive license be renamed to for osi approval...so permissive license == public license.

UPDATE2: (old) community license == (new) receiprocal license

yeah, me too.  the news of the day is that microsoft's developer group is releasing portions of the .net framework base class libraries (bcl) under the microsoft reference license (ms-rl).  in a nutshell the license enables the viewing of the source code, but no modification.  even so a step in the right direction in my opinion.  while it isn't an open source license, this is a part of microsoft's broader shared source initiatives to aid developers in the understanding of the innerworkings of the .net framework.

we'll also be introducing capabilities in visual studio 2008 to allow .net developers debugging their apps to not only step into their own source code, but also into the .net framework source code using visual studio!  aside from that functionality, anyone who accepts the license agreement will be able to download and view the source code.  the release will include the bcl, windows forms, asp.net, System.Data and .  this includes System, System.IO, System.Collections, System.Configuration, System.Threading, System.Net, System.Security, System.Runtime, System.Text, System.Data, System.Web, System.Windows.Forms, System.Windows.  you may not see or / or linq (linq is yet to be released anyway) but each library that is considered to be released under this initiative will go through a review process.  additional libraries are planned as time progresses.

you can see a demonstration and more details on scottgu's blog as well as listen to shawn burke discuss it on hanselminutes.  integration with the debug symbols is going to be as simple as:
