IronPython 1.0 is Born
dougblank writes "IronPython version 1.0 was just released after 3 years of development. Jim Hugunin, the creator of Jython and the lead developer of the Shared Source IronPython, made the birth announcement earlier this week. From the announcement: 'I wanted to understand how Microsoft could have screwed up so badly that the CLR was a worse platform for dynamic languages than the JVM... I found that Python could run extremely well on the CLR — in many cases noticeably faster than the C-based implementation. [...] Shipping IronPython 1.0 isn't the end of the road, but rather the beginning. Not only will we continue to drive IronPython forward but we're also looking at the bigger picture to make all dynamic languages deeply integrated with the .NET platform and with technologies and products built on top of it. I'm excited about how far we've come, but even more excited by what the future holds!'"
...does it run on Mono?
I found that Python could run extremely well on the CLR in many cases noticeably faster than the C-based implementation.
Actually, that's not really something to be proud about (though I'm not downplaying the huge achievement of running python on the CLR). The C implementation of Python is not very optimised, and that's why projects like PyPy or psyco are trying to speed Python up (and succeeding very well). I've had CPU-intensive scripts (such as SortSize) run tens of times faster with psyco, by just adding a line of code to my script.

[IronPython] [ANN] IronPython 1.0 released today!
.NET 2.0 such as DynamicMethods, blindingly fast delegates and a new generics system that was seamlessly integrated with the existing reflection infrastructure.

I started work on IronPython almost 3 years ago. My initial motivation for the project was to understand all of the reports that I read on the web claiming that the Common Language Runtime (CLR) was a terrible platform for Python and other dynamic languages. I was surprised to read these reports because I knew that the JVM was an acceptable platform for these languages. About 9 years ago I'd built an implementation of Python that ran on the JVM originally called JPython and later shortened to Jython. This implementation ran a little slower than the native C-based implementation of Python (CPython), but it was easily fast enough and stable enough for production use - testified to by the large number of Java projects that incorporate Jython today.
I wanted to understand how Microsoft could have screwed up so badly that the CLR was a worse platform for dynamic languages than the JVM. My plan was to take a couple of weeks to build a prototype implementation of Python on the CLR and then to use that work to write a short pithy article called, "Why the CLR is a terrible platform for dynamic languages". My plans quickly changed as I worked on the prototype, because I found that Python could run extremely well on the CLR - in many cases noticeably faster than the C-based implementation. For the standard pystone benchmark, IronPython on the CLR was about 1.7x faster than the C-based implementation.
The more time I spent working on IronPython and with the CLR, the more excited I became about its potential to finally deliver on the vision of a single common platform for a broad range of languages. At that same time, I was invited to come out to Microsoft to present IronPython and to talk with members of the CLR team about technical issues that I was running into. I had a great time that day working through these issues with a group of really smart people who all had a deep understanding of virtual machines and language implementation. After much reflection, I decided to join the CLR team at Microsoft where I could work with the platform to make it an even better target for dynamic languages and be able to have interesting technical discussions like that every day.
The first few months at Microsoft were a challenge as I learned what was involved in working at a large company. However, once the initial hurdle was over I started experiencing the things that motivated me to come here in the first place. The team working on dynamic languages in general and IronPython in particular began to grow and I got to have those great technical discussions again about both how to make IronPython as good as it could be and how to make the CLR an even better platform. We began to take advantage of the great new features for dynamic languages already shipping in
We were also able to release IronPython publicly from Microsoft with a BSD-style license. In the agile spirit of the project, we put out a new release of IronPython once every three weeks (on average) over the course of the project. This helped us connect well with our daring early adopters and receive and incorporate their feedback to make IronPython better. We've had countless excellent discussions on the mailing list on everything from supporting value types to calling over
Is Python being used to fix Microsoft's mistakes? Or did a python got run through the Iron Chef competition? Either way, does it taste like chicken?

Duh, duh, duh duh duh.

Faster than CPython (ya know, the original upstream Python implementation), not faster than C.
Well, the links to the FAQ don't seem to work thanks to some kind of site move (I am asked to download the HTML instead of view it and ... well ... am too lazy tonight). But a few thoughts based on what is already there:
I guess I just don't get it.
Instead of trying to impress us with innuendo and Microsoft bashing, the summary would have been a lot more helpful if it were written a different way. Oh, I don't know...like maybe for instance...TELL US WHAT THE FUCK "IRONPYTHON" IS! But then I guess, after all, that is the Slashdot Way. Why waste time on informative content when you can print Microsoft jabs instead.
I want a new quote. One that won't spill. One that don't cost too much. Or come in a pill.
Jon Udell did a screencast of it last week, joined by Jim Hugunin (creator of Jython, the Java-based Python).
I think IronPython compiles down to CLR bytecode, so if you're shipping managed C#, you could just as well ship IronPython and nobody would notice, which is the entire point of this article in the first place.
However, whether or not you could benefit from learning Python is a decision only you can make. Python may increase your productivity 2-3x over C# or more (and that's fairly conservative, usually), but only after you learn it, which could be months.
However, if you end up always choosing the short-term expedient answer of sticking with the language you know (and the environment you know), you lose out on any productivity gain you might get from another environment or language; this is a general point, not one specific to this case.
In general, the "common environments" (Java,
Again, I'm not trying to push you, just point out that for the costs there are benefits, too. I say what I'm saying because I believe (and see) too many developers trapping themselves in local maxima by always making the short-term decision. Ultimately, it's no skin off my nose.
You can, but the lack of namespacing starts to get troublesome as you start trying to build libraries, or use the libraries of others. Later versions of Javascript, which JScript will presumably track, will help with this a lot. Although based on what I see, it's nearly learning a new language anyhow. (In fact, the next version of Javascript borrows a lot from Python; generators are basically from Python, array comprehensions are from Haskell IIRC but the syntax is the Python one, and the most main-stream language with de-structuring assignment is Python.)
My apologies for making a trollish post. I was in a pissy mood earlier, firing from the hip, and should have thought my words more carefully. I completely agree with you, actually, regarding your point to the following:
A lot of people I went to school with couldn't get it. It may have been that the people who didn't get it were the ones that I met in the Information Systems classes (which, where I went to school, was a concentration on a Business Major, where they taught VB as the intro language) were those that were not cut out to be programmers in the first place, thus affecting my perception of languages causing dain bramage.
Anyway, I still don't like VB, but, at least you made me consider my words and thought processes. Apologies to the community at large for being a dick.
