4/35 What is the avg CPI rate of a 2-way superscalar processor (in-order
execution with branch prediction, caching, etc...)? I'm just looking
for some ballpark numbers.
\_ are you asking for number of issues per cycles or execution latency?
\_ issues per cycle.
\_ it's around 1 or 2 on average. cpus these days grab blocks
of instructions at a time. |

4/35 So I'm just like ya know sitting here and like thinking that like
some DBZ would be cool right now and then hey like there it is.
\_ What is/are DBZ?
\_ The only good thing in your life. |

4/35 ILOVEYOU virus. got it, did a save as, removed .vbs extension.
in the .txt file , there is a name:
rem barok -loveletter(vbe) <i hate go to school>
rem by: spyder / ispyder@mail.com / @GRAMMERSoft Group /
.. Manila,Philippines - turin
\_ "Starting today at 1pm, UCLink will block all emails with
'ILOVEYOU' in the subject line"... morons....
\_ I feel safer now. Maybe they should be block all emails
with vbscript instead? Naaah, it's too useful for uhm...
email virus writing.
\_ Wow! You discovered the same thing as a few hundred thousand others
\_ Wow! You flamed this moron! You're sharp enough to post
garbage on this motd!
\_ "Starting today at 1pm, UCLink will block all emails with
'ILOVEYOU' in the subject line"... morons....
who looked at it with an editor, more, less, and cat, and what was
reported in numerous online articles by zero-tech clueless fucks!
You're sharp enough to be a writer for zdnet or wired! So you
think we should send the CIA to Manila and kill everyone named
barok who attends school? Good call. I hear they're already on it. |

4/35 Does aluminum foil or white sheets of paper reflect more light, if the
direction of the reflected light is not important? -- yuen
\_ Are you talking about strictly visible light? IR? UV?
\_ I'm interested in daylight (5500K). -- yuen
\_Christ, get a clue. Get a strong light source and a dark wall.
Hold up a sheet of paper and a sheet of tin foil that are the
same size. Measure the size of the square of reflected light.
Estimate the intensity in a small area, and multiply by the
entire area of the reflected light. Very simple. Any fourth
grader could do it.
\_ WAG (wild-ass-guess): Metal over paper any day. However, to test,
put some paper and aluminum foil out in the sun for a few hours. See
which is warmer.
\_ This is incorrect advice. Just because something 'feels' warmer
does not mean it is. For instance, titanium watches feel
neutral on your hand, but steel watches feel cold (when you first
put them on). However, both are at the same (room) temperature.
The subjective sensation of coldness can often be caused by the
_rate_ of heat transfer, not the actual temperature. In the case
of watches, steel has a greater heat transfer rate, so it absorbs
more heat from the human skin in the same amount of time than
titanium. These rapid temperature changes is what the human
skin's thermal receptors are most sensitive to.
-- motd physics god
\_ i knew this, too. - motd physics weenie
\_ as tom pointed out on wall, this won't work for another
good reason: paper transmits light, aluminum doesn't.
so you need to check the temperature as well as the trasmitted
light. -ali
\_ take both into a dark room and flash a flashlight at them...
have it reflect against a wall. seems like a logical
test *shrug*
\_ this doesn't take into consideration the fact that aluminum
is specular and paper diffuse. the pattern on the wall will
look different. you need to add the TOTAL amount of energy
\_ Who cares?
reflected everywhere on the wall, not just look at the intensity
at one point on the wall. the only good quick way i can think
of this is to point a thin laser at the paper, measure the
reflected intensity at some angle, and scale to the rest of the
hemisphere, and do the same with aluminum, but measure the
reflected intensity near the surface normal. -ali
\_ The two sides of my foil differ. Which side you talking 'bout?
\_ If you want to grow pot, don't use aluminum foil. _Very_ hard to keep
flat enough to reflect light.
\_ I think of it this way - mirrors are made of melted metal (I don't
know which) poured over the back of glass. Mirrors are *very*
reflective. I believe that part of the reason is that the glass
holds the metal flat. Put paper on the back of glass, and you
don't get anything particularly reflective. If my life depended
on it, I'd choose aluminum. |

4/35 Back in my Good Ol DOS days, i used to create a ram disk for fast
read/write scratch space. How would I do this under linux? -crebbs
\_ Aren't files supposed to be cached in RAM?
\_ Files are "cached" in RAM. However, they must exist on disk
first. What i want to do is create a partition of RAM, say
/ramdisk, which i can write files too, work on and which
will stay around untill I delete_them/turn_off_the_computer.
\_ This is what swapfs is for. I don't know if it
exists under linux or not. Yuo can usually mount it
as /tmp.
\_ Geeze, would you bozos get a clue before you give stupid
answers?
mkdir /ramdisk
mke2fs /dev/ram5 5000 (that's 5 megs)
mount /dev/ram5 /ramdisk -tom
\_ Why do you feel you need this? If you think it will make accessing
files in the ramdisk faster you are almost certainly wrong. I
suppose a ramdisk might be faster under weird situations. If you
think ramdisks are good just because they were under DOS, don't
bother. --Galen |

4/35 Who the fuck is erasing 30%+ of motd replies in the past 3 days?
\_ I think it's crebbs. At least he last edited it before this most
recent spate of deletions. --motd witch-hunt god
\_ tom is the unofficial motd purger. -!tom
\_ This motd sucks. Why doesn't someone either write a program
to manage this, install ultimateBB on the csua web page,
or start a csua newsgroup server? |
