I've asked before and ML has refused. It doesn't hurt to ask though.

Knowing how Matt talked about the code, it may not be that bad, at least to him.

I don't think it would be a good idea. It would open the site up to vulnerabilities, that I doubt many people would feel compelled to step up and fix. Allegro development and the forums in general are both slowing down to a crawl. We need new life, and old members back.

I think we should put together a fund to advertise allegro.cc.

Now that Trump is President(elect) we can make Allegro great again!

With enough activity, open sourcing software makes it less vulnerable.

It doesn't really require much activity at all. It mostly hinges on the size of the code base. More code means more eyes are needed. In general, not sharing the code doesn't prevent attacks, and most importantly, what is the cost of somebody hacking A.cc? Relatively little. Especially if ML has offline backups of the data.

I don't imagine that it would be feasible to implement a safe and expressive language to query it without risking security. Sure, it could expose data in various ways, but it would still be orders of magnitude slower than querying the database directly. It would probably be more useful if ML published a yearly database or something. My memory is foggy, but hasn't he done that before? (Obviously, such a database would need private user data securely stripped...)
