• World's Worst Paint Program

  I've uploaded the World's Worst Paint Program, as seen in my PDC talk, to IronPython's CodePlex site: http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=28125#DownloadId=93331 This is built using Visual Studio 2010 Beta 2 and the IronPython Read More...

• Microsoft.Dynamic - Getting Started w/ a Language

  Want to create a language on top of the DLR? Well the first thing you need to do is plug into the language side of the hosting APIs. Once you've done that you'll also discover that you have a bunch of additional functionality which enables you to quickly Read More...

• Two IronPython releases in 1 week

  This was a good week for IronPython - we've released not one but two new versions! The first release was IronPython 2.0.2 which just includes bug fixes for issues which have been particularly irritating to our users. This is a very minor release and doesn't Read More...

• On Performance

  Ahh, performance… It’s so much fun! It’s easy to measure and as you work on it you can see immediate benefits (or not!). I personally enjoy getting to spend time looking at interesting performance issues and I’ll use this as a time to plug IronPython Read More...

• A Simple DLR Binder

  A lot of people find it a little confusing to write their first binder to consume dynamic objects running on the DLR. It’s not actually super simple but it’s not too hard either. To shine some light on this I thought I’d post a very simple binder that Read More... Posted Wednesday, January 21, 2009 7:11 PM by DinoViehland | 1 Comments Filed under: binders, metaobject, DLR

• IronPython, MS SQL, and PEP 249

  Over the past week and a half I've spent a little bit of time getting Django 0.96.1 running on IronPython. The 1st step in doing this was getting a database provider that would run on .NET that would work with Django. For DB backends Django basically Read More...

• New opportunities...

  After a little over 4 years it’s time for me to go and explore new opportunities… It's awesome to see Whidbey out there now and I'm sure the work we did to improve the reliability of the CLR and embed it in SQL Server will pay off for our customers. But Read More... Posted Thursday, November 17, 2005 12:24 PM by DinoViehland | 0 Comments

• Fiber mode is gone...

  Well, now that our RTM and RC-esque builds are starting to make it out into the wild it seems like a good time to discuss a feature we had to make go away... That feature which most readers of my blog are probably now familiar with is fiber mode. So why Read More... Posted Thursday, September 15, 2005 1:38 PM by DinoViehland | 3 Comments

• Cooperative Fiber Mode Sample - Day 11

  Last week we went over the Abort and RudeAbort APIs. This week we’ll go over Fiber.Exit. This API provides a way for you to terminate a running fiber, and demonstrates a use of the unmanaged ICLRTask::ExitTask API. The ExitTask API can only be called Read More...

• Cooperative Fiber Mode Sample - Day 10

  In this article we’re going to look at the implementation of Abort and RudeAbort. In the last article I mentioned that a typical host wouldn’t need to expose these to managed code. Why is that? If you have a fiber mode scheduler typically Thread.Abort Read More... Posted Thursday, September 30, 2004 5:15 PM by DinoViehland | 0 Comments

• Cooperative Fiber Mode Sample - Day 9

  The managed Fiber class exists in its own directory in the SDK sample appropriately called Fiber. The Fiber class is designed to be vaguely similar to the managed Thread class. For example, like the Thread has ThreadState the fiber has FiberStates. The Read More... Posted Thursday, September 16, 2004 3:24 PM by DinoViehland | 4 Comments

• Cooperative Fiber Mode Sample - Day 8

  It seems like a good time to take a breather and look at what we have going on so far. First, we’ve started the runtime. We’ve handed our IHostControl off to the runtime. The runtime has called back to our IHostControl and gotten a couple of managers. Read More... Posted Thursday, September 09, 2004 11:25 AM by DinoViehland | 0 Comments

• Cooperative Fiber Mode Sample - Day 7

  At this point we’ve covered nearly all the major components of the unmanaged host. The one remaining detail is the interface that’s used between the managed fiber mode implementation and the unmanaged host. This is all implemented in callbacks.cpp. We Read More...

• Cooperative Fiber Mode Sample - Day 6

  The synchronization primitives are handled off to the runtime by the IHostSyncManager interface. We’ve already provided this to the runtime through our GetHostManager callback on IHostControl. Our IHostSyncManager is implemented on our IHostTaskManager Read More... Posted Friday, September 03, 2004 3:04 PM by DinoViehland | 0 Comments

• Cooperative Fiber Mode Sample - Day 5

  Last time we successfully created a task and started it running. That’s an accomplishment, but there are a couple of details we should get out of the way before we start to dive deeper into the fiber mode implementation. Those are all on IHostTask and Read More...
