John Lam announces that LOLCODE on the DLR is now available.

INVISIBLE HAPPINESS

Microsoft’s John Lam and Jim Hugunin go large with the DLR at MIX07. Here are my notes whilst listen­ing and watch­ing the presentation:

What to expect: a Mac, Text­Mate, Javas­cript, Python, Ruby, Safari and Silverlight.  Text­Mate equals text edit­ing. Sil­ver­light is not bin­ary, its just XML and text. You can break it apart and look at the gooey­ness inside. And some friendly Microsoft people ban­ter­ing about Ruby vs Python.

And DLR is going Open Source, like Iron­Py­thon.

What strikes me the most is that the lan­guage that people are com­fort­able with: Javas­cript, Python, Ruby, C# — you can code your cli­ent side in the same lan­guage as server side.

Also, hav­ing Ruby instan­ti­ate Javas­cript and call func­tions. Wow. With a C# object doing UI. Tech­nor­ati via XML through Yahoo!Pipes to JSON to Sil­ver­light on a Mac. Retriev­ing from the JSON object deseri­al­ised and quer­ied via LINQ.

Let alone doing Basic, with REM and all.

In their only Power­point slide, Jim details the per­form­ance gains of Iron­Py­thon on the CLR engine. I won­der if the perf gains are going to match to Ruby, too? Is the DLR/CLR going to be the saviour of the scal­ing bumps of Ruby?

Parts of the DLR (from Jim Hugunin at end of video):

1. Dynamic type sys­tem, shared object system
2. Shared host­ing API; host one, get all of ‘em. ruby bits are com­ing together now.
3. Bunch of help­ers for com­piler writers, so dynamic lan­guage runs fast

Ques­tion: can use DLR inside con­sole, ASP.NET?

Answer: yes, you can use DLR any­where you are using .NET. More con­strained in Sil­ver­light, due to the sandbox.

Ques­tion: is it com­pil­ing an assembly, or execut­ing script

Answer: Dynamic meth­ods in .NET 2.0, for code gen­er­a­tion lazily; and is a dynamic method. Only held whilst there is a live ref­er­ence. ASP.NET scen­arios with stress test not held onto. Not using method rental; System.Reflection.EmitDynamicMethod

Ques­tion: JScript.NET vs. new Dynamic Lan­guage Jscript?

Answer: Developer want lan­guage pur­ity, not tight integ­ra­tion and fol­low­ing .NET. So fol­low the ECMA 3.0 spec. That’s Javas­cript. vs. Ruby “freelove” spe­cific­a­tion of Ruby is its imple­ment­a­tion, not a spe­cific­a­tion document.

Microsoft has changed, big time. My head is spinning.

John Lam, why Dynamic Lan­guages from John Udell pod­cast:

express­ing my intent in the code.

Inter­est­ing inter­view between Tim Heuer and John Lam on Ruby as a part of the announce­ments yesterday.

The Ruby sup­port from Microsoft is more than just Sil­ver­light; it also crosses into the server and the cli­ent, out­side the browser.

21^st Cen­tury Small­Talk: Iron­Py­thon 2.0 in a browser, per­form­ance and dynamic fun.

Miguel de Icaza, lead of the Mono pro­ject (open­source CLR) on the new Dynamic Lan­guage Runtime:

Bin­ar­ies of the DLR were released today as part of Sil­ver­light 1.1, and the source code was included with Iron­Py­thon 2.0 (also released today).

The release for the DLR is done under the terms of the Microsoft Per­missive License (MsPL) which is by all means an open source license. This means that we can use and dis­trib­ute the DLR as part of Mono without hav­ing to build it from scratch. A bril­liant move by Microsoft.

Keep­ing secrets is tough. Hear­ing about the Dynamic Lan­guage Runtime (DLR) from John Lam in Feb­ru­ary this year was one of those secrets that kept well.

John Udell inter­viewed John Lam, and has a back­grounder here. Some in the Ruby com­munity didn’t see this com­ing.

Jim Hugunin has a post­ing on the new DLR, open source nature of the DLR on his “Think­ing Dynam­ic­ally” blog.

In addi­tion to the Sil­ver­light release, we’ve also made the full source code for both Iron­Py­thon and all of the new DLR plat­form code avail­able on code­plex under the BSD-style Microsoft Per­missive License. All of that code can be down­loaded today as part of the Iron­Py­thon pro­ject at codeplex.com/ironpython.

The real­ity of being able to debug Ruby in a client-side UI frame­work on Safari on a Mac using Microsoft Sil­ver­light tickles me, and oth­ers, greatly.

Blog from the key­note today, with all the ups-and-downs. Good to see I am not the only one who craves demos and has sub­vers­ive thoughts in the midst of formal sessions.

Ryan Stew­art has com­ments, and fur­ther links. The DLR adds 400K (what the!) to the Sil­ver­light down­load. Wow.

zdnet has a sort of tran­script of the Q&A that occured with Mike Arring­ton, Ray Ozzie and Scottgu.

Does Microsoft get Web 2.0? Yes.
