11/29   From the CSUA minutes:
        - Next Gen Console
        -- If we have $1800 in our accounts, should we buy a console:
           4 votes passes.
        -- Console voting: 2 votes each, neither passes
           * 360 = 600, more games
           * PS3 = 650, not as many games
        Does this mean the CSUA already has a Wii?
        Since when is, "more expensive, fewer games" an argument for something?
        I guess if they're gonna install Linux and try some Cell development,
        THAT would be cool, but I don't think that's what they want it for.
        \_ Netrek is free.. but you need to have skills
        \_ I think the decision should be based on which you can hack and/or
           boot alternate OS's on.   I think there is a clear answer here...
           \- YMWTS: KYELICK et al paper "The potential of the cell processor
              for scientific computing" on the POWER of the CELL. Interesting
              and quick read. Note: KYELICK now the Director of NERSC.
              \_ Yeah, but Roadrunner (A combo Opteron/Cell cluster proposed
                 at Los Alamos) is still a dumb idea.
                 \_ Why do you say that?  I'd be more concerned about using
                    /panfs as the storage system. Panasas might be ok by the
                    time it is deployed. A lot of impressive people there,
                    but mixed experiences in practice.
                    \_ The Cell already has a perfectly good general processor
                       attached to it.  (A dual core power 5).  What's the
                       Opteron doing there?  The last thing the Cell
                       development tool kit needs is another totally different
                       processor to work with.  Yea! A third compiler!  For
                       hevean's sake, they don't even have the same endianness!
                       processor to work with.  Yeah! Another compiler!  For
                       hevean's sake, the don't even have the same endianness!
                       \- ibm and amd are working together on a few things
                          like socket compat between POWER-tng and Opteron,
                          and Torrenza(sp?)/HTX rather than PCIe. the HPC space
                          is very different from the rest of the world ...
                          on a $100m computer you have a legion of programers
                          to work on tweaking code, compilers because they
                          are no longer dominated by "expensive programmer
                          time costs".
                          \_ While everything you say is true, I can't see how
                             that excuses creating a totally wacky, needlessly
                             difficult architecture.  Even Los Alamos
                             doesn't have infinite resources, programmer time
                             still costs money, money Los Alamos doesn't have.
                             Not to mention, they're buying the whole machine,
                             whole hog.  No small test prototype.  On a totally
                             untestest architecture.
                             \- no offense intended here, but are you just
                                reading articles on the net or do you have
                                some experience with how large HPC procurements
                                are done? i dont have any specific knowledge
                                of Los Alamos/Roadrunner but two things dont
                                ring true: 1. los alamos being on the hook for
                                all the dev and tuning work 2. ibm just being
                                responsible for dropping the machine off at
                                the loading dock and being done ... the "whole
                                machine whole hog" part. usually there are
                                lots of partial milestones involved. although
                                the somewhat dirty not that secret part of
                                this is those milestones are never missed
                                with major consequences. [well maybe once,
                                but not with one of the main *hpc* vendors.
                                i cant mention which well known vendor it was].
                                \_ Sorry, I didn't mean to imply what you've
                                   read into the 'whole hog' statement.  I
                                   guess that was really poor word choice.  I
                                   just meant that Los Alamos didn't buy a
                                   small prototype cluster to see how well this
                                   thing will work in production, as is
                                   normally done.  I'm aware IBM has milestones
                                   and will support the cluster.

1/14    Why is NULL defined to be "0" in C++ instead of "((void *) 0)" like in
        C?  I have some overloaded functtions where one takes an integer
        parameter and the other a pointer parameter.  When I call it with
        "NULL", the compiler matches it with the integer version instead of
        the pointer version which is a problem.  Other funny effect is that
        sizeof(NULL) is different from sizeof(myPtr).  Thanks.

4/29    Why were C and Java designed to require "break;" statements for a
        "case" section to terminate rather than falling-through to the next
        section?  99% of the time poeple want a "case" section to terminate.
        In fact some compilers issue warning if there is no "break;" statement
        in a "case" section.  Why not just design the languages to have
        termination as the default behavior, and provide a "fallthru;"

8/25    Why are iterators "superior" or more recently popular over the
        traditional method of using  for loops and indexing?
        \_ I guess it's because you can change an array to some other data
           structure (linked-list, tree, ...) without changing the loop code.
