I think Bruce will have opinions here, but IMHO using registers for arg passing isn't much of a win, especially on the x86 where there are so few of them. Register args win when the callee doesn't have to use the registers the args are in until they're needed. On the x86, it's more likely that the callee will need the registers and thus have to save the args somewhere else (like on the stack...), and thus lose worse. Another issue is stack unwinding; it's a real pain in the backside to unwind a stack that includes calls to functions taking register args; either the function saves the register args on the stack before the return address before calling out the first time, or you live with not being able to get the value of the arguments. Either way, I don't think that the improvements would be significant enough to be worth the effort. YMMV, especially on the 68K and some RISC targets where there are enough registers to make this worthwhile. > Obviously this would require rewriting a bit of the system call > dispatch code.

Um, I don't actually think that the stack is 'copied around' in the first place, and you'd still have to keep most of it because not all your syscall args are going to fit in your registers. - -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.

Precicely, and there is no reason why your time frame shouldn't be part of the query along with the terms. The more dimensions you can describe, the more accurate the retrieved set will be. The problem with hypermail is the timeframes are pre-set, and not necessairly in a very useful fashion. The fact that the current arcihves on www.freebsd.org do not allow retrieval by date is, in my mind, a catastrophic failing. > Write a good free IR system? :-) Its hard! IR is theoretically bankrupt.

Force people to use DHCP. It isn't perfect, but better than letting a bunch of newbies configure their own systems. A proxy like cached or squid, which both work under FreeBSD could also solve your address shortage problem. The entire 10.x.x.x block has been reserved for non-connected sites, and these addresses could be given to given to internal campus machines. Proxy servers like cached can also reduce Internet traffic, and speed access to common pages. > Thanks in advance > > Chris Coleman (chris@aries.bb.cc.wa.us) > Computer Support Technician I (509)-766-8873 > Big Bend Community College Internet Instructor > Death is life's way of telling you you're fired. > > Tom ------------------------------ From: Terry Lambert <terry@lambert.org> Date: Tue, 19 Nov 1996 18:28:09 -0700 (MST) Subject: Re: Who needs Perl?

If you don't want the boring details, or you want to figure the joke out for yourself, don't read the rest of this message. It probably belongs on -chat anyway. If you are a great fan of PERL and don't want to be annoyed, well, you've been warned. 8-). This was a 3-level English pun based on a single initial English pun used to back-handedly reference PERL. (1) At STP, diatomic Lithium the metal is a solid (someone claimed all diatomic metals, except Mercury, are solid at STP; Hydrogen isn't. 8-)). (2) This forces a reinterpretation of "is a gas" as a colloquialism instead of a direct interpretation. The use of the colloquialism is a bit archaic (tantamount to using the word "groovy", I suppose); however, there is a Rolling Stones song "Jumpin' Jack Flash", in which they use it "Jumpin' Jack Flash, it's a gas, gas, gas...", and it was The Clue in a Whoopie Goldberg movie, titled after the song. (3) How can Lithium be "a gas" in the colloquial sense? Lithium salts are used psychopharmacologically in the moderation of N-dopamine uptake. A chronically mentally ill person with Schitzophrenia is most likely suffering from: (1) a genetic predisposition to having fewer than is considered normal N-dopamine receptors, or (2) smaller than is considered normal N-dopamine production, or (3) has a chemical imbalance interfering with N-dopamine uptake. Item (3) can be environmental poisoning -- for instance, Aspartame (Nutrasweet) bonds to N-dopamine receptors. Do not drink most diet sodas if you are borderline Schitzophrenic, or change the amount you drink if you are already on medication. In a "normal" person, Lithium use would result in reduced brain function. So we see that if he "would sooner snort powdered lithium", he is probably referring to it's psychotropic properties... implyimg that, though Lithium reduces brain function, it does not reduce it so much as programming in PERL might... hence the second order pun.

This is called an "IP Proxy Gateway", and requires both a service agent on the gateway box, and a "WINSOCK.DLL" or "WSOCK32.DLL" on the client machine that knows how to connect to the proxy server over the transport. As a point of general information, the IANA is not responsible for assigning well-known-sockets on IPX (or SPX)... Novell itself is. In order to get an assignment, your application must be NDS (NetWare Directory Services) aware. As another point of interest, the only value in NDS in this case in in service advertisement for the proxy gateway service. To get around this problem (requirement), most third party developers have been using IPX diagnostic broadcasts to locate servers. This is very dirty, and Novell is bound to do something to stop it in the next release or so. > Do we have any plans for implementing it? > > BSDI and the Novell have it.

If you were to write a winsock, and you made it use SOCKS to connect to a SOCKS IP Proxy Gateway, your name would be heralded from the tops of towers, in many circles, since it would mean the death of the hated "aliasing".

This is a way of working around it that I had temporarily forgot about. With hosts before bind in /etc/host.conf, and an entry for the local hostname in /etc/hosts, the lookup will be avoided. I forgot about that because there is some reason (can't remember it right now; could be something that was fixed long ago) why I couldn't do that to host.conf on the particular machine because it interfered with something else. However, in the general case for someone getting mail via uucp with a dial on demand type network connection that will solve the problem.
