A) Infants with velcro mittens can now
work in important airport security
screening jobs. Making them productive
taxpaying citizens much sooner after birth.
or
B) This is cool, but have we determined that
infant development as it is, is not healthy?
Perhaps the time lag to develop motor skills
before exploring your enviromnent was an
important factor.
C) Velcro Mittens can also be used for people
on medication who can't hold onto pencils.
Upon discovery, the NSA has sent federal agents
to people in the act of procreation to arrest
them for violation of the national securities
act. When queried a spokesman responded:
"We can't allow these codes to fall into enemy
hands, and also need time and additional funding
to be able to decipher these codes for national
security reasons"
Before we can act on your bug report, "new class of bug" we need a reproducable testcase.
You did not indicate in your email what operating
system you were running and what revision of "World" software you were using when you discovered this bug. If this bug is only observed once every
50 years, it will be difficult for us to track
down and remove the bug in time for the next
release of "world", hence the request for
a repeatable testcase so that we may observe
the bug for ourselves, and attach a debugger.
Also, please indicate if this bug results in
a system down, or if there is a work around
for this bug.
Another solution would be to store a small amount of super cooled Beer stored as a Bose-Einstein Condensate. (No matter that they haven't yet cooled beer to a nano-kelvin yet..) After you shoot the laser beam at the bad guys, the heat is shunted to the Bose Einstein Condensate which becomes Cold Beer!
It's Miller Time!
I think there was a SCI FI book called the Difference engine, where "Clackers" used steam powered mechanical computers to run programs on
punch cards.
Now all we need is a really tiny keypunch machine.
I can see it now... PKPA Personal Key Punch Assistant.
Does this also mean CPU will mean Card Punch Unit?
I grew up in a world where we had Linux/Unix
before Windows. I would recommend a Mandrake
install with High/Paranoid security setting.
To me this is much tighter than the old Win95/98
do nothing password.
I would set the systems up stand alone in a
local subnet perhaps using IP Forwarding such
as the Cable Modem HOWTO for a home network.
Then either get a static IP from your IT folks
for a WIN computer or run a DHCP client on the
single node that connects through to your University LAN. (i.e. to make it easier for your
IT people... have only ONE node tied to the IT
network, and manage your subnetwork in your
classroom yourself).
My opinion of any WIN only sys admin type is VERY
LOW. This would be the difference between an
auto mechanic (Linux Sys admin), and the guy who
does oil changes only at QuickLube (WIN sys admin).
All fear of Linux is based on ignorance. It is
truly a superior and more elegent solution and
a MUCH better way to teach students how computers
actually work, than the Win XX platform.
I'm reminded of an Isacc Asimov story
(I believe) where the main character actually
read books and learn, and was an outcast because
he didn't conform to the pre-programmed training
syllabus of computer learning machines in use
in his future world. Turns out this individual
was recruited to the secret cadre' of people who
wrote the computer learning packages at the end
of the story.
A Linux user can live in a Windows world and
be successful, however a Windows user cannot do
the same.

If you have a Celeron or better, you can hook

This is the link to info on how to use this.
I want someone to post the link where if
I browse to the link http://www.xxx.xxx/blah.htm
I get a new file created on my disk.
I challange anyone to create such a link to
exploit this security hole that
would create the file slashdot.txt in C:/tmp
(OK you don't have to create the directory too).
I leave this as an exercise for the student.
IF someone is bright enough to create this link,
I would be happy to go there and verify that this
is a bug. In the meantime, I'm using Opera.
This would do more to support the bug weakness
than any of these posts.

Took me a bit to figure this. I guess this
training is primarily on how to set your alarm
clock so that you wake up early enough daily to
reboot your employerrs NT servers. I understand
that NT servers need this daily.
Ugh.. sanity is doomed!
I worked with a company which sells multi million
automatic test equipment (ATE), for years this
equipment was Sun based. About 18 months ago
I was at an off site office location setting up
an off line workstation. A new hire was watching
me setup the/etc/printcap file and some dummy
user accounts so users could use this new machine
on the network without YP running.
His comment was... why don't we just use Windows
wouldn't it be easier? I had to hold back my
reply... who hired this guy?
Now I work at a compnay which produces lower end
test equipment. We have a Windows NT box, which
uses MS C++. Although I hate it, once I got over
the handcuffed GUI, it actually works (sort-of),
this of course, means I will never be able to
sell internally a superior Linux based solution.
I was at DeVry about a year ago recruiting for
my old company. It turns out that 99% of their
courses are MS Windows based. They were CONSIDERING offering a UNIX class. This is terrible!
What it means is that there are lots of talented folks who think MS Windows is the
way to go. Kind of like religion.
I've actually found people who like 'vi'
over emacs too!
I believe that primary computer training should
begin with a semester of loading up Star Trek
via paper tape into a 110 baud Teletype, then
playing the game. The highest scoring players
get 'A's. After this, users would realize that
you can load and play an entire game of Star Trek
on a Teletype over a coupler in the time it takes
to boot windows ME.

So, let me see..
I'm moving into my new house in 2010,
called the power company, called the phone
company, called the cable company (broadband),
and the gas company... say gas company,
can I have both hot and cold gases?
I think if you look at the datasheet for the G4
you will find that it has the lowest power dissipation of all the CPU IC's out there.
From my research the heaters are
(excluding SUN)
Compac Alpha
AMD K5/K6 (they vary by process used)
Intel PentIII/Celeron (vary by process used)
Motorola PPC line
All the processors followed similar power/speed
curves, with the Motorola PPC being the coolest
as it is a RISC CPU and has slower clock speeds,
for what appears is similar performance. (Based
on market acceptance, not benchmarks).
I'm guessing that at these small geometries, the
heat per transistor is smaller due to the small
currents involved. However the thermal density
and switching speeds might wipe out all this gain.
It's heat density per unit area that is making
these chips efficient space heaters.
I too like light-based chips. However there is
a significant amount of energy required to lase
the light in a laser diode. This keeps getting
more efficient.
I expect as Infiniband technologies pick up, there
will be more and more folks playing with light,
and we will start seeing some inroads in this area. I have stock in Corning. I figure they
know glass cookware, so they should do OK making
glass cable.
Just a FYI 3.3Terahertz is a 303 femto second period. How many electrons can you move around
in 303 femtoseconds?
If the clock is running at 3.3Thz, (assuming this
is not a clockless chip) it leaves about 102 femto
seconds for a rise time measurement, and 101
femto seconds for a fall time measurement.
(Looking at the pulse).
Projecting further I woud expect the rise time
zero to 50% point would be about 50 femtoseconds.
I'm supposed to know this, but can't recall the
rule of thumb for the oscilloscope bandwidth I
would need to look at this, but I'm guessing I
would like more than 4Terahertz... I'd really
be comfortable with about 8-20Terahertz bandwidth
on the scope... or somthing that could digitize
the signal at 20 Terahertz or so (20THz = 50fs).
I'm sure this analysis is flawed, but I just
like to imagine that I could actually look at
a 100fs rise time with a scope in about 5-10 years.
-- Ross
I was thinking the same thing, and it occured
to me, that they could use a Butt print, as
we would assume most customers have a butt to
sit in the car with. In fact, they could
include butt activated ignition, to prevent
you from leaving the engine running if you
get out of the car.
The only trick is using the Butt activated keyless
ignition, where you have to moon the inside
passengers to get into the car.
This is not a new problem. I was in a meeting
over 15 years ago where this discussion came
up in the design of high speed ECL ASICS for
applications such as the CRAY Y-MP. With ECL
devices having FMAX from 600-800Mhz in the early
'80s propigation delay was a critical factor.
The rumors I heard were that CRAY accounted for
every millimeter of path length from the IC
core, to the pad, through the wire bond, out
onto the PCB, through the wire wrap etc and onto
the next PCB. All of this I suspect without
the "advanced" CAD routing tools we have today.
All of the heat management and prop delay issues
in high speed ECL systems of the late 70's early
'80s are now getting onto the desktop.
-- Ross
This is terrific... with a terahertz CPU core
we will all need to buy new Infiniband I/O devices
to keep up!
With the cost of ATE at $1-5 million to test these
IC's we will probably see some more shifts to
structural testing and serial I/O to keep manufacturing costs down. I wouldn't expect to
actually see a 64 bit bus running at 1Ghz, but
stranger things have happened.
