I begin to wonder if this is the way a Smalltalk or Lisp-machine-like live environments can be resurrected for 2013?
Also, directness isn't liveness. But then they don't define live at all, so it could mean anything.
How many attempts to create the perfect ide for programming the web, in the web, and yet we keep the distinction of what is source "file" and what is the app being run, and how you debug it. Smalltalk and it's developing environment made blurred this boundary, and might be a great inspiration if not a practical solution.
I find what Bracha is doing in NewSpeak to be much more interesting and up to date with modern times. Just rehashing a 20 year old interface and putting it in the web is great from a retro perspective, but it doesn't move us forward at all.
It is high time to move out of Smalltalk's shadow.
The good thing about bring it back to life is for educational purpose, as, unlike many other research, smalltalks tended to have more complete and mature development environment, and I believe it might be inspiring get a feel of how to do things that way, I doubt any kid today will be inspired by doing something on vxworks
Yes... is not popular as Java, or .NET, or even Python. But banishing a language for not being popular is the worst argument I ever hear.
I don't understand why you are offended because I said that smalltalk is dead. It's just a way to say that it's not mainstream and probably it will never be again. And the sad thing is that for most part the reason of its reduced popularity has nothing to do with its technical merits, but this deserves a whole thread and if I remember correctly it has been covered many times before.
Check out http://en.wikipedia.org/wiki/Genera_(operating_system) for some basic info on what a Lisp Machine was like...
As such a Lisp environment in a browser is a nice achievement and it looks like a fun project. Naturally it is far away from a really sophisticated system like Genera. Still, it is interesting to write something like this small project. Though I would prefer something which would be compatible with Common Lisp and would allow reuse in that direction.
If people would want to know more about Genera, the operating system, the Wikipedia article is a good source. If there is something missing, we should add it.
Kalman Reti (who worked for Symbolics for many years) gave a presentation: http://kvardek-du.kerno.org/2013/03/kalman-reti-on-lisp-mach...
I've asked someone else if they might respond to you with some further and more useful info. Hopefully they can!
I think, given this is a newbie-oriented tutorial, the alert should be more helpful, like "empty program, select some text first!" instead of unexpected null character.
I'm really excited to see such great ideas of the past being resurrected like that. Things like Lisp machines and Smalltalk environment are still revolutionary and have much to contribute to the technology of the present.
It's a shame really that they almost died out. I could only guess what were the reasons for that but it's great to see efforts trying to bring them back to the future where they belong.
FYI; I'm at the limits of my understanding here, so if you're a compiler or CPU architect and you doubt what I'm saying here is true then you're probably right ;)
