End-of-thread time? Well, if one is going to get into that kind of bragging, the first *mainframe* I worked on didn't have any disks at all. purely mag-tape based. An early- generation IBM system/360 with a whopping 64k words of _core_ memory. The operating system was TOS (the Tape Operating System), predecessor of DOS, which the machine was upgraded to when they got a couple of hard-disks for it. Single user, bare-bones batch processing, punch-card input. late 1960s. I learned FORTRAN back in summer quarter '78 on a CDC-6400 that used punch cards. Had to use my _nose_ to finish one card. The 6400 took up a chunk of the basement of Evans HAll and had a HUGE 64k of core! That's the limit of my bragging--er, commenting:-) TOS? snicker, LOL, ROFL ... Yawp. Really. TOS and DOS. Those _were_ the names the two OS varients were known by. Not too long thereafter, IBM decided the minimum configuration would include disk packs, And 0S/360 became the universal choice. As for the 6400, it had 64k words of 60-bit (each word could hold 10 characters in the internal CDC character set) memory. roughly 2x to 2.5x the capacity of the 64k 32-bit words on the IBM. I programmed on the 6400, and it's big brother, the 6600, for a number of years. An absolutely _lovely_ architecture at a high level it was a beatutifully simple architecture, with a machine-language that you could learn in an afternoon, if you'd had any exposure to _any_ other assemler language. The instruction set was _so_ rational, you didn't need a cheat sheet (aka, green card, yellow card, whatever) to keep track of what was what. Now, admittedly, the closer you got to the hardware, the more strange the machine got. It's the only machine I know of, where CPU HALT is an _unpriviliged_ user-mode instruction. and one where user programs are *expected* to use it to end every program. And, of course, the 6600 architecture (the 6600 was the original model, 6400s were introduced later as a 'economy' version) as one other endearing characteristic. It *can't*add*. At the hardware level, addition is done by 'complement and subtract'. And the CPU clock is more than 10x faster than memory read cycle. Memory is 32-way(!!) interleaved, to keep up. Oh yeah, the machine -really- annoyed computer-science purists. Up to the limit of data that you oult fit in main memory, an optimized _bubble- sort_ was faster than =any= other sorting algorithm. This came as a *RUDE* surprise to more than one first-year C.S dept faculty member. There was always some smart-*ss in the class who got the bubble-sort implementation right, and it ran in far less time than even quicksort. If you did _careful_ benchmarking, you could see that when the data-sets got large enough that the 'expected' (bubble-sort loses) behavior _was_ there. but the cross-over/break-even point was at a point that was _larger_ than the maximum main memory that you could hang on a machine with only an 18-hit address-space. Uuser apps were limited to only 17 bits of addressing. It also freaked some people that you could copy a dataset that was many times the size of main memory, using only _one_ buffer, and isusing only *one* 'read and *one* write instruction. The operating system was 'management by committee' at the _hardware_ level, and could literally be doing _20_ different things simultaneously. Start one member of the 'committee' transferring data from the 'source' into the buffer, and hav a -second- member transfering _out_ of the butter to the destination, and just sit ack and watch them go at it.

Re: acroread9 crashing
the freebsd linux emulator is missing support for the inotify_init syscall. you won't be able to use acroread9, until it gets implemented. right now i guess it returns ENOSYS to any linux app making use of it. you might be able to work around this problem by replacing ENOSYS with 0. however since no actual work is being done i suspect this won't make acroread9 run properly. you might want to drop Roman Divacky (rdivacky@) a note. he may have some experimental patches at hand. cheers. alex On Sat Oct 23 10, Jerry wrote: FreeBSD 8.1-STABLE /amd64 I continue to have a problem getting acroread9 to run. 1) It will not create its directory in my home directory. :1: error: unexpected character `\1', expected keyword - e.g. `style' Acroread was unable to create the directory .adobe in your home directory.

Something like this: EHLO smtp.example.com By default it will use the hostname of your server, but you can override that. It is this address that you have to be really strict about: the address should resolve to the IP that the server connects via (not necessarily the IP of the server if there are NAT gateways involved), and a reverse lookup of that IP should return the name again. This name used in the EHLO banner doesn't have to be anything to do with the addresses on the e-mail, except in as far as either side is using SPF and you have chosen to add that information to the SPF selector(s). SPF seems to be going out of favour now, and sensible mail admins didn't make accept/deny decisions entirely on pass/fail of SPF tests, but still, for best results with a mail system, you should take care to get that right.
