Subject: Re: conservative gc sucks From: Erik Naggum <email@example.com> Date: 14 Jan 2003 15:38:50 +0000 Newsgroups: comp.lang.lisp Message-ID: <firstname.lastname@example.org> In the unlikely event anyone else reads Tom Lord's increasingly spurious excuses for articles... * Andy Freeman | Can this reliably work on Unix? * Erik Naggum | If you delete an open file, what exactly do you want to rely on? * Tom Lord | That the data in the deleted file is still accessible to programs | holding a descriptor for that file. That the file name may be | re-mapped to a new inode, even while the previous inode is still in | use. Are you speaking for Andy Freeman? Did you understand the /context/ of the question he asked? Or are you just jumping into a discussion to which you have not been paying much attention so you can say something stupid and pretend it is somebody else's fault? * Erik Naggum | Why would you want to enroll such an open file in this | mechanism? Recall that the mechanism discussed here is one of keeping track of a number of /files/ by name, which can be opened and closed at will. If the files cannot be opened and closed at will in this fashion, then use your goddamn brain and do not use this technique! How hard can it be to grasp that just because a technique has limitations does not mean it is not useful where those limitations do not apply? What kind of a programmer are you if you are unable to grasp this? * Tom Lord | Because these semantics are part of how good unix programs achieve | ACID semantics. Let me get this straight. You want automatic flushing of buffers and closing of files upon garbage collection of streams so you can implement certain algorithms which you claim are not easy in Common Lisp as is (except that it is, you just use finalization). When a simple scheme is proposed that would free you of all concerns for when files are opened and closed (which seemed to be the point of your desires until you came up with more problems after the old ones were solved) for some particular uses (I proposed only two such schemes depending on usage factors, obviously not the exclusive list of methods, but the /obvious/ choices for how to implement what you claimed was /obvious/ yet did not understand), your counter-argument is that it should not be used because you want /ACID semantics/ of these garbage collected and automatically opened and closed streams? Are you /insane/? Or are you just making up problems as you go so that nobody can ever satisfy your increasingly irrational demands? | It may be the case that sometime in the future, we'll be able to | wrap unix filesystem calls in begin-/end-transaction wrappers -- but | for a few decades now, people have made good use the very easily | implemented semantics under discussion to achieve ACID properties | without full-fledged transactions. Are you at all aware of what thread this is in? Does the word "context" not have any meaning to you at all? Is thinking so hard for you that you have to concentrate real hard and work long hours not to make bumbling mistakes? Is that why your miserable excuse for a brain overloaded when you were given standard sociological arguments about models and you called them "jaw-droppingly dumb"? I take some solace in the fact that the arguments were given by a professor of sociology at the U of Oslo who has published dozens of papers and books. When you, an obviously harebrained fool, pays no attention and provides evidence that you are so mind-numbingly retarded that you should be protected from yourself, that is one of the things he has discussed over the years -- how people who are poor on mental models seek out and need information that conforms to their models lest they become very nervous and agitated and feel an urge to escape rather than to think. | Argument for argument's sake? Yes, that does indeed seem to be your modus operandi. | If the earlier questions were honest, | I've provided the answers to them. Except for the fact that they were asked of Andy Freeman, not of you. Except that you do not appear to be particularly honest to begin with. Except that you answered questions completely out of context. Andy Freeman had already swayed from the context, but you showed me what kind of idiot you are when you decided to respond. You probably think that just because your feeble brainpower cannot deal with something, it must be dumb. Astonishingly stupid people tend to behave that way. It must be fun to be you. I sometimes wish I had accepted the drugs I have been offered at various parties of the years so I could have been able to /relate/ to people like you and how your brains work. -- Erik Naggum, Oslo, Norway Act from reason, and failure makes you rethink and study harder.
