Yeah, so now the arguments run out and you try to find a hair in the
soup. Sure there are sinful people in a church. If anyone in a church
claims to be without sin, run, because he or she is lying.

I'm just proving that Phil's statement is false. There is no argueing
about that. There is wrong everywhere but the way the church tries to
cover things up is beyond sickening.

I'd certainly have had to be asleep to miss it, especially since it came
out in 2002 in the US. Nor is it limited to the Church--schoolteachers,
for instance, have a far worse record, at least over here.

As a Dutchman, if you really want something to turn your stomach, try
investigating the origins of all those trafficked slave women in the red
light district of Amsterdam. IIRC about 4 out of 5 were trafficked from
Russia and eastern Europe, and they suffer rape and worse, continually,
until they're too sick or too worn out to be worth anything any more.

Well, if you want to see unhappy women you should go to the red-light
district. However, your information is a bit outdated. Many laws and
regulations have been put in effect to minimize the possibility of
human trafficking and enslavement. It is very difficult to get a
permit to open a sex-club (aka massage salon). Even the well known
Yab-Yum has been closed down by the local authorities because there
where rumours the owners had ties with the criminal circuit.

Outdated? From what I have heard they have discovered a new source of
"revenue" and are now taxing the redlight districts:

No useful specs.

That is normal with many Asian suppliers, got to get used to it and test
a lot for yourself. You can sometimes obtain additional data from them
but sometimes you'd have to be married to the CEO's cousin's daughter or
something like that.
"Test a lot?"  What does that tell me?  It went against my grain to use a
green LED (GaN) at 3.3V.  "Because one works..."  Well, at least if the next
lot doesn't work we'll know.  

I didn't mean a lot as in production lot, but as in "a lot of testing"

Meaning some of the properties have to be measure. In some designs that
is the only way to succeed because there are no parts that can
"formally" do what you need them to do.

http://www.rohm.com/products/discrete/transistor/complex/#03
"Very small package with two transistors."

All those aren't fast though.
Me?  I don't need fast.  ;-)

Lucky you

Almost all my stuff is RF nowadays.
We buy modules for all that stuff.  I wouldn't attempt it with the shoestring
capital budget we're on (we're down a scope and it doesn't appear that they're
going to even replace it).

A scope? That's scary. I hope that doesn't mean any bad news. You can
nowadays get a lotta scope for $1-2k.
Or a Rigol, for $350.

That may be bit skimpy. I often find myself debugging and finding things
on the digital side, where everyone was 110% sure it couldn't possibly
be a software issue. That's mostly SPI and other serial buses where 2ch
won't really work. Also, I found that 100MHz BW ain't enough. Glitches
in systems where a 8051 screams along at 80MHz or so are specterally
above that.

That's been my point when management (and the other engineer) suggest that
100MHz is enough.  Gotta have at least 3X, 5x is better.

No need for 3x or 5x here. I have a 200MHz BW scope with 1GSPS realtime,
cost me about $1800 including tax. If things get any faster then I can
usually make them repetitive, at least on a temporary basis, and fire up
the old HP. That only has a 40MHz converter but a very good one and its
BW is 1GHz.

It's just so weird to see the words "8051 screams along" run together like
that.  ;-)

Like this

http://www.youtube.com/watch?v=pBD0YpdRf4Y

I am not a gigital guy but AFAIK there aren't too many other uCs that
you can clock at 100MHz.

We use an NXP ARM LPC1754, and it can clock at 100 MHz. Since it's a
register-rich 32-bit RISC thing, it really screams. We buy them
programmed with our code and laser marked from Arrow for $4.75 each.

you can even get the lpc1759 that will run at 120MHz, but it has 4x
the
memory so it will cost a bit more

it is impressive how much processing power you can get in a single
chip
that really only need a 3.3V supply and sometimes an xtal

We're also using LPC3250s, which clock at 270 MHz or some such, around
$8.

they need external memory that gets a bit more complicated

Gregarious instinct.

Usually it is a person, say Buddha, Jesus, Krishna, Ram, Mohammed.
These people were real and were able to show their followers a divine experience in side of them.

The christianity as a concept is ~300 years older then Jesus. The
success of the christianity is mostly due to the efforts of Paul rather
then Jesus himself. Mohammed was an indoctrinational officer of the Abu
Bahr's army. Not sure about the others.

I am not talking about any worldly miracles like waking on water on winning wars or whatever.
I am merely talking about some process *inside a human being* that needs to be understood,
and when understood is the key to a life long happiness.

Human being is an animal. Understand this, quit thinking, quit talking
to yourself and quit pretending to be what you are not. That's the
whole secret )))

As society is set to look for happiness *outside* yourself, for example in western
society by acquiring more material wealth, objects, power, or whatever you

Acquiring stuff -> endorphins -> happiness.

Why not. This is no better or worse then any other method.

Crusades happened later, murder, inquisition.
Mass hysteria, total stupidity...

That always was and always is.
Nothing changed.

Absolutely nothing to do with a divine experience or understanding what was at the basis of it all.

Well if everybody will absorbe in nirvana then who will be cleaning the
shit?

Nothing 'mild' really., and still today the pope plays his games, plays his masses.

The Pope is just a CEO of the Catholic Church, Inc.

and the real experience NOW in this life is replaced by a promise for after death,

Life after death is another way for not paying the bills. The efficient
doctrine should produce the results now, here and for real.

So, to make a long story short, for the real truth look within, there is bliss there, or at least it can be.
It is simple, and there is something there that needs to be understood.

at least it is legal and regulated, so there's hope those who work
there
do it of their own free will

just like drugs prostitution won't go aways just because you ban it,
it
just means criminals will make money providing it, with no regulation
what so ever

Oh yeah, if we give up fighting it we just make it legal. Sorry, but you
will not convince me of that. I have lived in the Netherlands for about
6 years and seen the sad aftermath of that. Including some funerals.

I buy as much equipment as I (financially) can. Even though I use some

I measured some GHz rf transistors for a pulse application a couple

The old-fashioned brute-force way was a long-tailed NPN with a vicious

When you break the 1nsec barrier all those measures are off-limits.
Everything must be shorter than 1/10", impedance-controlled, and zero

No useful specs.

That is normal with many Asian suppliers, got to get used to it and test
a lot for yourself. You can sometimes obtain additional data from them
but sometimes you'd have to be married to the CEO's cousin's daughter or
something like that.
"Test a lot?"  What does that tell me?  It went against my grain to use a
green LED (GaN) at 3.3V.  "Because one works..."  Well, at least if the next
lot doesn't work we'll know.  

I didn't mean a lot as in production lot, but as in "a lot of testing"

Meaning some of the properties have to be measure. In some designs that
is the only way to succeed because there are no parts that can
"formally" do what you need them to do.

"Very small package with two transistors."

All those aren't fast though.
Me?  I don't need fast.  ;-)

Lucky you

Almost all my stuff is RF nowadays.
We buy modules for all that stuff.  I wouldn't attempt it with the shoestring
capital budget we're on (we're down a scope and it doesn't appear that they're
going to even replace it).

A scope? That's scary. I hope that doesn't mean any bad news. You can
nowadays get a lotta scope for $1-2k.
Or a Rigol, for $350.

That may be bit skimpy. I often find myself debugging and finding things
on the digital side, where everyone was 110% sure it couldn't possibly
be a software issue. That's mostly SPI and other serial buses where 2ch
won't really work. Also, I found that 100MHz BW ain't enough. Glitches
in systems where a 8051 screams along at 80MHz or so are specterally
above that.

That's been my point when management (and the other engineer) suggest that
100MHz is enough.  Gotta have at least 3X, 5x is better.

No need for 3x or 5x here. I have a 200MHz BW scope with 1GSPS realtime,
cost me about $1800 including tax. If things get any faster then I can
usually make them repetitive, at least on a temporary basis, and fire up
the old HP. That only has a 40MHz converter but a very good one and its
BW is 1GHz.

It's just so weird to see the words "8051 screams along" run together like
that.  ;-)

I am not a gigital guy but AFAIK there aren't too many other uCs that
you can clock at 100MHz.

We use an NXP ARM LPC1754, and it can clock at 100 MHz. Since it's a
register-rich 32-bit RISC thing, it really screams. We buy them
programmed with our code and laser marked from Arrow for $4.75 each.

you can even get the lpc1759 that will run at 120MHz, but it has 4x
the
memory so it will cost a bit more

it is impressive how much processing power you can get in a single
chip
that really only need a 3.3V supply and sometimes an xtal


We're also using LPC3250s, which clock at 270 MHz or some such, around
$8.

they need external memory that gets a bit more complicated

-Lasse

Right. We boot them from a plugin serial flash chip, which also holds
an enormous FPGA configuration file. The 3250 is for high-end stuff
that needs the compute power and hardware floating point and DRAM and
junk that the 17xx chips don't have.

A gold-doped BJT would be nice as well. However, I have not seen any

There are several old-line PNP saturated switches that are gold-
doped. I don't remember the part numbers off hand, but they're in the
old Nat'l Semi transistor book. 2n4209, maybe?


* DROOL *

Anyone aware of one that's still made, and small?

pant, pant, drool


They're pretty fast, ~1 or 2 nS edges IIRC, but not saturating them is
better still.

Some day I'll have to see how the BFT92 and the BFG31 behave. But they
are intended as amplifiers so they won't are about saturation effects.
Trick to keep it out of saturation get old quickly when every pF and
every thenth of an inch count.

I measured some GHz rf transistors for a pulse application a couple
decades ago. They're VERY slow if you let them saturate--don't let
them!--but scream if you don't.

The old-fashioned brute-force way was a long-tailed NPN with a vicious
L-R pull-up (or current source) collector load.


When you break the 1nsec barrier all those measures are off-limits.
Everything must be shorter than 1/10", impedance-controlled, and zero
nanohenries. All it takes is a wee bouncy-bounce into saturation and
game's over.

The real "wall in the sky" is at 100 picoseconds. That's where things
get seriously difficult.

Far from it.  Properly, the Church is organized so that no one is

Right now its dinner time over here but I suddenly lost my appetite!

I'd certainly have had to be asleep to miss it, especially since it came
out in 2002 in the US.  Nor is it limited to the Church--schoolteachers,
for instance, have a far worse record, at least over here.

As a Dutchman, if you really want something to turn your stomach, try
investigating the origins of all those trafficked slave women in the red
light district of Amsterdam.  IIRC about 4 out of 5 were trafficked from
Russia and eastern Europe, and they suffer rape and worse, continually,
until they're too sick or too worn out to be worth anything any more.

Well, if you want to see unhappy women you should go to the red-light
district. However, your information is a bit outdated. Many laws and
regulations have been put in effect to minimize the possibility of
human trafficking and enslavement. It is very difficult to get a
permit to open a sex-club (aka massage salon). Even the well known
Yab-Yum has been closed down by the local authorities because there
where rumours the owners had ties with the criminal circuit.

Outdated? From what I have heard they have discovered a new source of
"revenue" and are now taxing the redlight districts:

http://www.breitbart.com/article.php?id=D9KMSBS81&show_article=1

it's a job/business, why shouldn't they pay tax like everyone else?

at least it is legal and regulated, so there's hope those who work
there
do it of their own free will

just like drugs prostitution won't go aways just because you ban it,
it
just means criminals will make money providing it, with no regulation
what so ever
