Why is Arc built onMzScheme vs other Scheme implementations?
4 points by thaddeus 5218 days ago | 11 comments
Curious to know why mzscheme was chosen. From a performance perspective I would think Gambit would be a better choice. Or are there other reasons?

Anyone notice that titling on postings are being modified by the program or something else?

Seriously - Originally I had thought it was just me, but I am noticing this more now.

Even google cache proves it's been changed:

I imagine it's the same as http://news.ycombinator.com: editors (e.g., pg, though I'd guess there are others) can change titles, usually to correct grammar. Not as much headline-editorializing can happen in a forum such as this (versus news.yc), so titles probably get edited less here.

I think that's an incredibly bad idea, particularly when 'they' are not improving the data.

Welcome to the news.yc discussion circa about 2 years ago ;)

In the case of this title, the only way it got "worse" is that someone goofed on a space, "onMzScheme". An editor could now step in, add a space, and the only difference would be that proper nouns were capitalized. Not that the edit was wholly necessary, but it's not like the title was censored.

It's really kinda funny. When I post, I notice the submit function capitalizes the first letter of the first word of the title's sentence.... sometimes I look at that and say to myself - hey! that's not what I typed!. So I go back in and edit the title changing the first letter back to lower case as intended (correct or not). The update function allows this to pass through. So now that I see (more than once) my text being changed I find myself feeling like I have to battle the bots (or the nots!). It just feels wrong.

That's good to know about being able to edit the first letter back to lowercase -- on occasion I've started a title with a function or macro name that should be uncapitalized.

Ah yes. Thank you. It's always good to hear from the horses mouth....

Me 154 days ago: "Just by making mzscheme salient arc is responsible for getting me hacking more on lisp." (http://news.ycombinator.com/item?id=700869)

Not really an answer to your question, but it was immensely useful to be told, "Just pick this one."

hmmm... too bad. I have yet to try gambit, but I like the idea that it's fast, supports 64 bit systems and along with termite http://code.google.com/p/termite/ there's concurrency model similar to Erlang. Though I am not sure that would even work with arc, but at a faster version of arc with a concurrency model sounds better to me.

I'm just in this investigating/researching languages + features mode lately :)
