Well, there are certainly cases where you grab a reference speculatively; anything where you need > N in a collection to act on, for instance, but don't know how many items there are yet (such as when you're reading from a stream). The

Haven't done much Perl hacking, good to know it's more-or-less pure reference counting. Paging can occur as a consequence of copying a reference. var p1 = *A // let p1 be a reference to A // something in the interim var p2 =

A memory leak is pretty terrible, and having to either a) disallow cycles or b) specially handle them in user code is also pretty terrible IMO. Loads of handy graph data-structures, all sorts of fun caching techniques just got either impos

Pure reference counting doesn't handle cycles. I believe those languages (and I'm pretty certain Python does) implement a periodic mark-and-sweep GC for those cycles. So you still periods of high latency collections (in .NET only Gen2 coll

While this possible using the profiling interfaces, it's not really much simpler IMO. What happens if more than 1 server needs to GC at the same time (or overlapping times)? You definitely don't want to pull everything out of rotation, so

No, Facebook is replacing their forums with Stack Overflow. See their blog post: http://developers.facebook.com/blog/post/545/ Their documentation remains independent, the alternative is insane. (disclaimed: SE Inc. employee)

In the literal sense that you are not your e-mail, yes email != identity. In a practical "on the internet sense," your email really is your identity (maybe SSN or name would be a better description; you can change it, but to do so is cata

I definitely get the impression that Jeff is more surprised than upset by users who have used cookie-based accounts for long periods. If I recall correctly, the record for longest "active unregistered account" is around 2 and 1/2 year (Sta

SO gets well over 10k completely new posts (Q&As) on a typical day. A few thousand older posts are edited a day. Throwing comments into the mix more than doubles the number of "new things", and of course every question, answer, comment,

Its mostly a distinction between "can login with one click (Registered with OpenId/Facebook)" and "can login with a crazy convoluted path (provide email [again], check email for link, etc.) (Unregistered)". You can get the lion's share of a

Ah, my bad; been a long time since I've had to do anything as an unregistered user, mis-remembered. Looking at the code, we do require something that looks like an e-mail, for recovery purposes (I assume, that code predates me by a bit).

No, you can participate (well, post answers/questions; no rep is gained) as an unregistered user without giving us an e-mail address at all (or even giving us a bogus one, we don't check). If you do provide one, it lets you recover your coo

There is a way to recover your account if your cookie is lost. http://stackoverflow.com/users/account-recovery (this is linked from /users/login) It does require that you provided a valid e-mail address at some point, which we don't requi
