9/26    When my client, get's disconnected I get a message "reset by peer"
        Does it mean, csua reset's my session or, My ISP disconnect's me,
        from the session?
        \_ Why all the extraneous apostrophes? don't people even pretend
           to know grammar anymore?
           \_ 311T3 Hax0012 D0 ! N33D G12AMMA12 D00D
        \_ It means that someone tried a tcp hijack on your ssh session
           and the server broke the connection. Otherwise, soda rebooted.
                \_ Or you hit soda's 24 hour keepalive timeout and your
                   ISP's firewall isn't playing nicely.  (Or your ISP
                   session timed out & you reconnected with a new IP
                   \_ or soda crashed and rebooted.
        \_ It means your lost your connection.  Why do you care?
           \_ Well, just wondering which side is doing the reset since it
              happens quite frequently, if it's not from csua, then I may
              be able to do something on my end to fix this problem.

9/26    Why is soda crashing so often these days? Do we need an upgrade?
        Perhaps FreeBSD 4.1.1 or something?
        \_ I believe that it is failing hardware.  I also think we need
           to upgrade.... not the OS but the hardware, though upgrading
           the OS at the same time as the hardware makes sense.  --PeterM

9/26     If I have lots of $$ and I want to buy a good laptop for running
         both windows98/ME and Linux, what should I go for?
         \_ PowerBook
         \_ IBM Thinkpads are nice in this area. All the ones I've seen have
            great Linux support, are built like tanks, and have nice keyboards.
            I have a 240, and even the built in winmodem works (though it can
            make things unstable) The new T and X series look really nice.
            If I had lots of money, I'd grab an X series box. Yum. -ajani
        \_ I'm in a simliar position (well, not *too* much money)... nobody
           recommends Vaio's for this purpose?
           \_ Sony VAIO is good. I'm running Linux on three of them. --dim
                 \_ How do you rate them in general?  I'm thinking of buying
                    one, haven't heard much outside of ads.  -sax
              \_ Anyone know when the Transmeta VAIOs are coming out?
                 \_ ask jeffwong, he works there.
                 \_ Don't bother, transmeta's technology is a big yawn.
                    I can give more details why on request.  -nweaver
           \_ am running linux and win2k on a n505-ve is working fine, except
              the winmodem is a rockwell and won't work under linux - ibms
                have lucent winmodems which do work under linux. - paolo
         \_ Dell Inspirons run Linux well.  They're heavy, though.
                \_ Yes, but does anyone know how to disable that damn
                   BEEP?  (can't be done in the bios)
                   \_ Which Inspiron do you have?  The 7000 doesn't beep.
        \_ I am buying Stinkpad 600X and Vaio picturebooks (the Crusoe
           ones, just cause I am curious) for work.  Stinkpads are
           great, and I believe that IBM now officially supports
           Leenux on them.  -John
        \_ Any opinions on Dell Inspiron 3800 ? -eric
           \_ 2 hour battery life, 7 lbs., so-so screens, good Linux.
              The principal developer here ordered 8 a few months ago
              for general use.  You know they just came out with the 4000.
           \_ I recently got one and I like it.  The screen is ok, imho.
              Dual pointers is a nice touch.  Linux & FreeBSD work nicely
              (except for sound).   I got mine very cheap ($1350 for 600Mhz
              with minimum ram and hdd) -- there was weirdness in Dell
              order system.

9/26    Is it just me, or it seems like Professors (and especially
        Professors) enjoy talking about the "good ol days when bytes and
        bits were THIS big and it's enough to get the job done" crap?
        \_ Whatever. When I was a kid we used to walk in 2 feet of snow
           to school uphills both ways.
           \_ Only 2 feet, what a wuss. I had to walk 10 miles uphill
              both ways in 6 ft of blizzard conditions just to go from
                                   \_ Playing Warcraft in the labs again?
                                      \_ I used computers to compute,
                                         not to play mindless games. Zork

              the classrooms to the labs.
                \_ Wow... you had schools?  Labs?  When I was a kid we used to
                   hear about kids that had the opportunity to walk to school
                   10 miles uphill both ways in the snow but never met any.
                   \_ I feel your pain.
        \_ people in every line of work do this.  i've seen old fisherman
           do exactly this on comercial fishing boats, and fishing is older
           than written history. "what are you whining about, kid? you think
           they always had refrigerated seawater on boats!?"
        \_ why would fishermen whine about the old days, when they hadn't
           yet caught all the fish?
           \_ And this is likely exacerbated by the fact that CS is a
              relatively young field.  A number of the Professors here today
              had a significant hand in shaping it.  They probably remember
              a time when it was possible to know EVERYTHING in the field.
              Wouldn't you miss that? -dans
              \_ Do you miss knowing something dans?  - dans' #1 fan
              \_ Quake 1 single player is a solved problem now.  Have you
                 seen Quake done Quickly?
        \_ Actually, Professors are mainly talking about making the BIG
           INTERNET BUX.
        \_ That's what happens when you get old and things change.
           \_ I'm starting to do that and I'm only 30.
              \_ I'm 30 and *not* doing that.  Try a new job.  Stay young.

9/26    Sun released USIII released today. It seems to kick major ass
        (of intel/amd/mot/dec) Anyone have a system yet?
        \_  You're deluded.  It doesn't beat alpha 21264 and only barely bests
            Intel.  It only excels in multiprocessing.  --PeterM
        \_  You're deluded.  It doesn't beat alpha 21264 and only barely
            bests Intel.  It only excels in multiprocessing.  --PeterM
        \_  I bet Sun does a better job of selling their crap than Compaq
                ever will.  Compaq still doesn't understand all the gems
                they have from that purchase they made a while ago.  Compaq
                weenies only understand NT and PC servers.
            \_ Intel kicks the ass of every processor we have benchmarked
               it against except for the new HP-PA chips. That does not
               include USIII, but it was so much faster for our (intensive
               number crunching) application than an USII 450 as to be
               laughable. USIII would have to be twice as fast or more to
               beat Intel, and these are only Intel 750's. --dim
                     MAYBE BECAUSE THEY CAN'T?
               \_ Sun is selling 900Mhz USIII's now.  SPECmarks
                  match a 1Ghz Intel on int and toast intel on FP.
                  \_ urlP
                  \_ I'll believe it when I see it. I don't trust SPEC
                     except as a very rough guide. So SUN's new processor
                     matches a 6 month old Intel chip, huh? That's supposed
                     to be impressive for the prices they charge? --dim
                     \_ 6 month old Intel chip?  There are about as many
                        1GHz PIIIs in circulation as USIIIs.
               \_ I've never seen intel kick any ass. MHz per MHz Intel
                  needs more than double to match PowerPC and Sparc.
                  \_ Duh!  So why don't they DOUBLE THE CLOCK SPEED to
                     what Intel can do and BEAT INTEL INTO THE DUST?
                     MAYBE BECAUSE THEY CAN'T?  Duh!  CPUs have to be
                     DESIGNED to clock fast!  Duh!  MHz is MEANINGLESS.
                     \_ Okay I should have said it this way, they need
                        more clock cycles to execute the same number of
                        instructions because while US/PPC can execute 4
                        int instr./cycle and 2 fp instr./cycle Intel can
                        only do 2 and 1 (I believe). Bascially CISC is
                        wasting your time by doing less in more time.
                        \_ But RISC takes multiple instructions
                           to do what CISC does in 1.  Comparing
                           instruction counts is as much as waste
                           of time as comparing Mhz.
                           \_ A RISC chip can introduce greater instruction
                              parallelism than a CISC chip can thus time
                              per instruction execution becomes important.
                        \_  Yeah, and they can't clock their complex (4/2)
                            RISC CPU fast enough to match Intel's relatively
                            simple CISC (2/1) in performance.  Why is that?
                            It is because they failed to design it to
                            clock fast.  Intel's is a superior implementation.
                            \_ No RISC is better. The only way that Intel can
                               keep CISC in the game is to keep ramping up the
                               speed. They can't improve performance in any
                               other way because of thier horrible design. Now,
                                    You seem to think that ramping up the clock
                                    speed is trivial.  You are wrong.  The
                                    CPU has to be designed from the ground up
                                    to be highly clockable.
                                    The MORE WORK PER CLOCK TICK, the longer
                                    the logic stage, the less you can increase
                                    the clock!  It's a tradeoff.  Designing
                                    something to clock fast was a smart choice.
                                    A winning choice.  Intel designed
                                    in such a way as to achieve high clocks.
                                    Other vendors did NOT, or else you'd
                                    see 1GHz PA-8500 uber alles.  But the
                                    fact is, no one can clock a PA-8400
                                    at 1GHz precisely because it was never
                                    designed to go that fast.
                                    Only the 21264 is demonstrably "better" at
                                    int stuff, and only barely.  The PIII
                                    and the K7 with their CISC are holding
                                    up just fine.
                               RISC chips can get the same perf at lower speeds,
                               giving them room to expand perf in all aspects.
                               The high end RISC chips can run at similar speeds
                               as Intel's fastest but they can run thorugh more
                               instructions in the same time. The other problem
                               with x86 is the bad assumptions about uniform
                               memory fetch latencies. Intel has made some
                               pretty bad assumptions about how cache fetching
                               works and have spend a lot of time improving thier
                               pipeline, while the bottleneck is really the time
                               it takes to satisfy a memory fetch from either
                               l1,l2,mm,vm. It doesn't matter what your pipeline
                               is like if most of the time its empty.
                \_ what a stupid measurement.  That's like saying a particular
                   car is slow because it revs higher.  -tom

           \_ Is the binary compatibily still there? There some problems
              when moving to 64bit mode on USII (esp 200 MHz ones in the
              UE2) and does it still run the 32 bit Solaris kernel (I
              gather that 32bit kernel is faster than 64bit kernel).
              \_ Yep.  Complete binary compatibility (I have no idea
                 what problems you're referring to with the USII - it
                 was binary compatible as well.)   No 32-bit kernel
                 though, 64-bit only.  Which is faster depends on what
                 you're doing.  -alan-
                 \_ For server work loads (ie non-compuational, non-db)
                    doesn't the amount of time required to search for a
                    given memory page in the 64bit address space cause a
                    noticable slowdown? And the problem with USII was
                    something to do with main memory fetch sometimes
                    failing on sub 200 MHz chip when the 64bit kernel
                    was running.
                        \_ Not that much of a slowdown, and on the plus side,
                           all 64-bit code is compiled with full UltraSparc
                           optimizations, while most 32-bit code is not.
                        \_ The only problem I heard of with < 200 Mhz Ultras
                           was the one where a bad instruction that no compiler
                           or assembler would ever generate could stall the
                           processer.  That's a bug, not a compatibility
                           problem.  (And fortunately for Sun, the actual
                           instruction was never publically leaked, unlike
                           the Pentium F00F.)  -alan-
