There two torx head patterns. The security version has a pin
in the middle of the head, which requires a matching socket on
the driver.
That said, driver bits for security torx are widely available.

Of course, wood screws differ from bolts, in that they are pointy so that they can go where there are no holes.
But what most people call bolts are indeed another kind of screw; I've
seen them also referred to as "machine screws". Presumably that's their official or correct name among professionals.

Look at my e-mail address and consider which countries use

https://www.youtube.com/watch?v=JYqfVE-fykk :-)
So Germany doesn't also use SAE for screws and bolts?...
Not sure what SAE prescribes. Is that Imperial? Germany (like
almost everybody else) use ISO, which is metric. An M6 screw,
for example, has a nominal outer diameter of 6 mm. Screw heads
are also ISO.
Or, have the same thing of building machines where half the screws are
SAE and half are Metric.
You will be hard pressed to find inch-based screws and bolts in
the EU, this is entirely metric. The only exception is Withworth
threads, which are still used for piping in houses. Of course,
these only bear a passing resemblance to their nominal diameter
because of $REASONS.
If not, are hex-head bolts still dominant, or is it like places where in
the US one would use a hex-head bolt or Allen-key screw they use Torx or
similar?...
Really depends on the application. Screws come in a variety of heads.
For bolts, hexagonal is dominant.
Then again, I guess if anything I would expect things like machines to
be similar, as most of the machines are presumably still made in China,
and it would be weird to expect China to make different stuff based on
what country they intend to sell it in.
I believe China looked around for their standards a few decades ago,
and decided to base theirs on DIN (the German one).
But, then again, I have heard there are sometimes issues, like a lot of
Chinese-made machines use copper-clad-aluminum wire, which is apparently
illegal in places like Australia, ...
Well, and I guess in the US, there are a lot of people who don't approve
of aluminum and CCA wiring, but generally still allowed (though CCA is
kinda annoying to solder as it can often foul up the tip on the
soldering iron and/or form an amalgam with the solder which can't really
be re-melted when if forms).
I don't think aluminium wiring is allowed in Germany. I have certainly
never seen it, also not in old houses.
But, yeah, I guess it is also sort of like in video games the units are
more ad-hoc, just whatever is most convenient at the time.
Though, in a lot of my 3D engines, this has been to use the meter as the
base unit, but then define an "inch" as 1/32 of a meter; then just be
like "whatever, close enough". Apparently fairly close to the old French
Inch though.
An inch is 25.4 mm, 1m/32 is 31.25 mm, that is a rather big
deviation. But then again, pi equals 3 for small values of pi
and large values of 3...
In some cases, can make sense to have a cubit as 1/2 "meter", or "foot"
as 1/3.
But, can't make too many assumptions it seems.
I was thrown off by the measurements in inches.
OK.
We have mm stuff as well, but it is less commonly used than inch stuff.
Tools and CNC machines pretty much exclusively use inches though.
Not so long ago, I was standing in a workshop in the US and asking
for a caliper in mm. They had one, but it took them some time to
find it :-)

Clearly there are military applications of a wide range of weapons. But >outside that, I can only think of a couple of reasons to want a fully >automatic weapon :
1. You are seriously paranoid or otherwise disconnected from reality,

The first clause of the second amendment says "A well regulated
Militia, being necessary to the security of a free State." For a
century and a half, its meaning was invariably understood to be that individual states could raise militias which we now call the National
Guard. Then in the 1960s some well organizaed revisionists ignored
what it says, pretended it meant an individual right to have guns
everywhere, and managed to find a majority of right wing supreme court justices willing to sign on.
This interesting paper argues that the real motivation for the 2nd was
that the slave states used their militias to put down slave rebellions
and feared that the more populous free states would disarm them.

Say target on single fire mode. Missed! Turn to auto and give a burst.
Or don't for what about 3 round burst? They are moving now. No single
sniper mode. A suppress fully auto can make the target think there might
be more than one person out there. Reminds me of the following scene:

Utterly insane would be if the same procedure applied to thermonuclear warheads.
Of course, much about the consequences of the Second Amendment indeed does appear insane. The sensible thing to do would be to repeal it, rather than pretend it doesn't exist, or it doesn't mean what it says, and hope the Supreme Court will look the other way.

Look at my e-mail address and consider which countries use
which measuring system. For your amusement, you can also watch
https://www.youtube.com/watch?v=JYqfVE-fykk :-)
So Germany doesn't also use SAE for screws and bolts?...
Not sure what SAE prescribes. Is that Imperial? Germany (like
almost everybody else) use ISO, which is metric. An M6 screw,
for example, has a nominal outer diameter of 6 mm. Screw heads
are also ISO.
Mostly it defines everything in inch-based units.
An M6 is roughly around the size of what we would call 1/4-20, for 1/4
inch at 20 turns per inch.
Or, have the same thing of building machines where half the screws are
SAE and half are Metric.
You will be hard pressed to find inch-based screws and bolts in
the EU, this is entirely metric. The only exception is Withworth
threads, which are still used for piping in houses. Of course,
these only bear a passing resemblance to their nominal diameter
because of $REASONS.
US has NPT, which has tapered threads, and differs from its stated size
by a factor of 2 because apparently they describe its size in radius or something.
If not, are hex-head bolts still dominant, or is it like places where in >>> the US one would use a hex-head bolt or Allen-key screw they use Torx or >>> similar?...
Really depends on the application. Screws come in a variety of heads.
For bolts, hexagonal is dominant.
OK.
In US it is mostly hex-heads for bolts, and Philips for small screws (followed by Allen keys).
Then again, I guess if anything I would expect things like machines to
be similar, as most of the machines are presumably still made in China,
and it would be weird to expect China to make different stuff based on
what country they intend to sell it in.
I believe China looked around for their standards a few decades ago,
and decided to base theirs on DIN (the German one).
OK.
Still seems like a lot of the stuff they sell to the US uses US sizes,
so maybe it is market dependent.
But, then again, I have heard there are sometimes issues, like a lot of
Chinese-made machines use copper-clad-aluminum wire, which is apparently >>> illegal in places like Australia, ...
Well, and I guess in the US, there are a lot of people who don't approve >>> of aluminum and CCA wiring, but generally still allowed (though CCA is
kinda annoying to solder as it can often foul up the tip on the
soldering iron and/or form an amalgam with the solder which can't really >>> be re-melted when if forms).
I don't think aluminium wiring is allowed in Germany. I have certainly
never seen it, also not in old houses.
Here, it is one of those "allowed but some people get pissy about it"
things when used for house wiring.
Frequently used in consumer electronics but no one notices.
I once encountered a wire that when voltage caused a spark to form, the
wire went off like a "4th of July" sparkler (basically, a metal stick
used for a US holiday, when the end is lit of fire, it burns and shoots white-hot sparks out the end, *1).
At first I thought it was CCA, but apparently it was CCAM (Copper Clad Aluminum-Magnesium). The CCAM wiring is probably the main stuff people actually need to worry about.
Though, AFAIK, pretty much no use uses magnesium for house wiring though.
*1: Where, the US has a holiday where the main traditional way of celebrating the holiday is to let kids play around with low grade
explosives and incendiaries. People have still been injured or killed as
a result of this, particularly when doing "something stupid".
Like, by themselves, their explosive powers aren't much of a problem,
but when contained in something like a beer bottle, or inserted into someone's rectum or similar, the danger goes up significantly.
Apparently this sort of thing is a recurring problem.
Well, and then there are people that celebrate by firing guns into the
air, but falling bullets can also pose a safety risk.
Sometimes, people have guns that are full auto. These are not usually
legal to have, but if one hears full-auto / rapid fire going off, then
it is an indication that someone nearby has one (and gunfire and machine guns can be heard over a fair distance). Well, also people firing
shotguns and similar into the air is also popular.
This sort of thing is also popular on New Years Eve, but almost
exclusively gunfire in this case (fireworks are mostly a "4th of July" thing). Depends a lot on the holiday though (say, would be rather out of place on Christmas or Easter).
Maybe this isn't as much of a thing elsewhere though...
But, yeah, I guess it is also sort of like in video games the units are
more ad-hoc, just whatever is most convenient at the time.
Though, in a lot of my 3D engines, this has been to use the meter as the >>> base unit, but then define an "inch" as 1/32 of a meter; then just be
like "whatever, close enough". Apparently fairly close to the old French >>> Inch though.
An inch is 25.4 mm, 1m/32 is 31.25 mm, that is a rather big
deviation. But then again, pi equals 3 for small values of pi
and large values of 3...
Yes.
In 3D gaming stuff, accuracy doesn't really matter, so long as things
are "in the right general area".
If using meters as a base unit, can put eye level at around 1.6 or 1.7
off the ground, as this is "about right" (1.8 is too tall and 1.4 is too short), ...
In some cases, can make sense to have a cubit as 1/2 "meter", or "foot"
as 1/3.
But, can't make too many assumptions it seems.
I was thrown off by the measurements in inches.
OK.
We have mm stuff as well, but it is less commonly used than inch stuff.
Tools and CNC machines pretty much exclusively use inches though.
Not so long ago, I was standing in a workshop in the US and asking
for a caliper in mm. They had one, but it took them some time to
find it :-)
Yeah, makes sense.
Most of them are inch based.

I first used the G3 at the Bundeswehr. 600 rounds per minute, 20
rounds per magazine. Firing that weapon at full auto will empty
it in a tid less than two seconds (note fencepost error here :-)
Firing short bursts or single shots will keep any enemy down for
a far longer time than that.
But a squad at the time had a MG3 (1200 rounds per minute) with it.
But firing that continously is also not a good idea because
a) ammunition: 24 grams per round means that you run through 0.48
kg (a bit more than a pound :-) per second of ammunition, which
somebody has to carry
b) you have to exchange barrels and locks after a certain number
of rounds to prevent overheating.

It also means that there are less guns stored in
concentrated places as potential targets for robberies. And in the
event of a real invasion, it's a lot easier to smugle around and
distribute firing pins to service members than to pass around guns from
a central armoury.
We also don't really go in for shoot-to-kill in Norway.

If you're referring to the United States,
No, I am referring to Norway. But it would have been helpful if I'd
mentioned that! (I expect similar rules and attitudes apply in
Switzerland.)
Ah, ok.
then those guns almost
never go home with those service members. Rather, they are
almost certainly kept in an armory on site at the NG facility.
The requirements for securing access to a US military armory are
non-trivial; when they're staffed, the service members doing so
are themselves armed and acting under shoot-to-kill orders.
The current practice in Norway is that National Guard members have their
guns at home, but no ammunition and no firing pin. This makes things
practical for exercises, as the leaders for the exercises don't need to
transport much - just a box of firing pins and as much ammunition as is
appropriate.
This is sensible, though of course a firing pin is much easier
to source than an entire rifle. In the US military, ammunition
is stored separtely from weapons, as well. The armorers have
some smallish number of security rounds, but beyond that, for
safety reasons ammunition is kept seperate, often underground.
(Ammunition is, by definition, volatile. A fire or something at
an ammo supply point is inherently dangerous.)
(The service members have all their other equipment at
home too - they store their own uniforms and other stuff, and are
responsible for washing and repairs or ordering replacements after the
exercises.)
The same is true in the US military. I always found it annoying
that I had to make space for my issued equipment at home, but
c'est la vie.
It also means that there are less guns stored in
concentrated places as potential targets for robberies. And in the
event of a real invasion, it's a lot easier to smugle around and
distribute firing pins to service members than to pass around guns from
a central armoury.
There are tradeoffs, however: it is also easier for a bad actor
to source a weapon by breaking into a private home.
We also don't really go in for shoot-to-kill in Norway.
Note that I'm talking about the use of deadly force to prevent a
bad actor from forcibly taking military-grade arms. That is
exactly the sort of thing that deadly force arguably _should_ be
authorized for.
But more broadly, from a military perspective, this doesn't make
a lot of sense to me, because it ignores the human factors at
play in the fog of war.
Due to the sympathetic physiological reaction to stress, one
tends to lose one's fine motor skills in a combat-type situation
and it can be difficult to remember even the most basic bodily
functions: lose of urinary and sphincter control are common,
for example (hence the expression, "scared shitless"). Moreover
long experience in human history shows that it is impossible to
know a priori how one will react: some people are ridiculously
calm in combat, others are not.
For that reason, most people are taught to shoot center-of-mass;
I was in the military when we still used iron sights out to 500
yards (roughly 500 meters). It's one thing to accurately shoot
at that distance when you're on a known-distance range on a
relatively calm day. It's an entirely different matter when
someone is shooting back at you. Anyone who thinks, "I'll just
shoot to wound them!" is deluding themselves.
But generally speaking, most military members are unarmed most
of the time. This is one reason why the Fort Hood shooter was
able to kill so people many before being subdued.
There is some leeway for officers and staff NCOs to transport
weapons to and from a range exercise in their POVs (Personally
Owned Vehicles), but the expectation is that they are returned
to the armory after use.
I don't know the details of any of that here.
It's not important. It was just an aside.
Oh, and you have to clean it before turning it back in, too, and
you have to do so to the satisfaction of a Marine Corps armoror
(well, you do if you're a Marine). That said, a little birdie
once told me that if you do a first pass and put a $20 bill in
the breach of the weapon when you turn it back in, they will do
it for you. But I wouldn't know anything about that.
We don't really go in for bribery either in Norway - at least, not at
that level. (In fact, not much at any level - we are not perfect, but
are one of the least corrupt countries.)
Lol, that's not bribery.

The same is true in the US military; there is a process of
"lining out" (at least, that's what we called it in the Marine
Corps; I can't speak to other services, though I assume the Navy
is similar) whereby you are physically searched and patted down
to ensure that you're not holding any rounds, intentional or
otherwise.
If you want trustworthy military personell, you need to trust them.
I can't imagine that any other professional military does it
much differently than I described.
This isn't about trust so much as accountability; the two are of
course related, but different. In particular, it's about
building a warrior culture that emphasizes safety and respect
for the inherent danger of weapons and puts inculcates practices
designed to emphasize and reinforce those traits. Ammunition is
inherently dangerous; it should be treated as such. The
expectation is that service members treat it with respect and
the attention that it inherently deserves. You build that by
enforcing accountability and then pushing that down through the
ranks to the lowest levels: a junior Marine is lined out by
their fireteam leader; the team leaders by their squad leader;
the squad leaders by the Platoon Sergeant, and so on. Junior
Marines see that this is taken seriously and so learn to take it
seriously.
In other words, you build trust that you just described by
emphasizing safety practices, and validate they are followed by
rigorous inspection, thoughout the mundate and ordinary aspects
of training. Hence lineouts, weapons inspections, and "clearing
barrels" that are all designed to habituate safe(r) weapons
handling practices.
Note that this is one of the things I find so troubling about
the "2A" gun culture in the United States. It fetishizes
weapons and deemphasiizes safety practices so that its adherents
can be "ready" at all times (for what?). These people aren't
just deluded about the relative risks of owning and carrying
weapons, they're actively dangerous because they have no idea
what they are doing.
As
a teenager in the UK, I was in the "cadets" at school - once a week we'd
have a few hours in military uniforms, learning marching, gun safety,
and a bit of fun stuff like camouflage, abseiling, and stuff. It also
included shooting at a barracks gun range - serious sized rounds with
long outdated rifles. We were just fifteen year-old "toy soldiers", and
we were /asked/ to check our pockets for extra rounds or empty casings.
That's disturbing.
Sounds like the people who ran your "cadets" program did you a
disservice by failing to emphasize proper weapons and ammo
handling practices.
Having worked with actual British forces in Afghanistan, I know
that they take weapons safety as seriously as we do. Perhaps
don't extrapolate from that to what an actual military does.

It is plausible, but AFAIK it is extremely rare here. The solid
majority of criminals here don't want guns, and would probably not take
one if they found one in a house they were robbing. As a house burglar,
you can't easily sell a gun, you don't need one for defence, you don't
need one to threaten anyone - it just increases your chance of being
shot yourself, and increases your punishment if you get got. There are
guns in the more serious narcotics gangs, but those are handguns - they
have no use for military weapons.
We also don't really go in for shoot-to-kill in Norway.
Note that I'm talking about the use of deadly force to prevent a
bad actor from forcibly taking military-grade arms. That is
exactly the sort of thing that deadly force arguably _should_ be
authorized for.
There is a distinction (which I did not make, but should have) between >authorising deadly force, and encouraging it. As a last resort, it
makes sense in situations like this. But it should be very much the
last resort. Real-life criminals are not like in the movies - if
military guards point guns at them, they will put their hands in the air
and no one needs to be shot. (It's a different matter for criminals
high on drugs and unable to think rationally, but they don't try to raid >military armouries.)
If shots need to be fired, the primary aim should
be to persuade the bad guys to surrender, not to kill them.

conditions as accurately as possible. You never get 100% simulation, of >course.
And you train for different tasks. Guards should /not/ be trained to
shoot to kill as a priority - they should be trained for identification
of the threat, de-escalation, and containing and controlling the
situation. The gun is primarily a threat - firing it at all is way down >your list of tactics. A successful outcome is capturing the intruders, >preferably uninjured - killing them is a failure (though not the worst >failure outcome). After all, most people the guard encounters will not

It is very different from having an official policy of fining people for

dishonest and actively taking ammunition, or thoughtless and
irresponsible enough to do so by accident. And you are telling them
that /they/ don't have to worry about safety - you'll take care of it
for them.
On the other hand, telling them to check all their pockets before

as a specific automatic task every time they leave the range, without >exception. It's the same as other gun-safety checks, like confirming
the safety on a gun you are handed even if you have just watched the

I first used the G3 at the Bundeswehr. 600 rounds per minute, 20
rounds per magazine. Firing that weapon at full auto will empty
it in a tid less than two seconds (note fencepost error here :-)
Firing short bursts or single shots will keep any enemy down for
a far longer time than that.
But a squad at the time had a MG3 (1200 rounds per minute) with it.
But firing that continously is also not a good idea because
a) ammunition: 24 grams per round means that you run through 0.48
kg (a bit more than a pound :-) per second of ammunition, which
somebody has to carry
b) you have to exchange barrels and locks after a certain number
of rounds to prevent overheating.

Tu. But, they can scare the shit out of the target. They know round are
going down range toward them. Therefore, they are in peril? But, the
ammo issue, ugg.
I first used the G3 at the Bundeswehr. 600 rounds per minute, 20
rounds per magazine. Firing that weapon at full auto will empty
it in a tid less than two seconds (note fencepost error here :-)
Firing short bursts or single shots will keep any enemy down for
a far longer time than that.
But a squad at the time had a MG3 (1200 rounds per minute) with it.
But firing that continously is also not a good idea because
a) ammunition: 24 grams per round means that you run through 0.48
kg (a bit more than a pound :-) per second of ammunition, which
somebody has to carry
b) you have to exchange barrels and locks after a certain number
of rounds to prevent overheating.
Where the military definition of overheating is: "The bullets no longer
go anywhere close to where the barrel is pointing".
5 rounds at 20 second intervals is enough to heat a sniper barrel
to the point it is not "accurate enough". Now, imaging those 5

Absolutely. No reason to have a finger on the trigger unless you intend
to open fire on something. Also, be sure to check the safety! Load a
round, put the safety on, point down range, pull the trigger over and
over again. It should not go off. Turn safety off, then it should fire.

While true, if someone tried to hand me a bolt-action rifle with
the bolt in place, I'd refuse. Likewise any magazine fed
weapon should not have a magazine installed and the action should
be open, if possible before handed to anyone.

Broadly speaking, they're a pain, and pretty much only useful as
either a suppression weapon or for guarding avenues of approach
to fixed defensive positions.
They're also extremely expensive to use and maintain. at $2.00 or
more _per round_, the cost rises rapidly.
Full-auto weapons are also heavy, and so is the ammo. Carrying
even a SAW is no fun after a few hours; a 240 or Ma Deuce? Not
happening. A Mk19? Forget about it.
Mythbusters shot a minigun on a couple episodes and the ammo cost
(more than a decade ago) was huge.
I suppose that the proponents will point to smaller weapons
systems, like submachine guns, that are full-auto but shoot
conventional cartidges (the Thompson shoots .45ACP, for example)
but they often don't realize that the kickback makes them
difficult to control. Even the 3-round burst on the M4/M16
pattern weapons will kick you off target almost instantly; that
mode is only useful as a direct fire alternative for suppression
to support advancing infantry in a complex attack scenario when
indirect fire is not viable, you don't have combined-arms
support, or you don't have crew-served weapons. It's like a
method of last resort.
I don't know why anyone would want a full-auto weapon as
anything other than a museum piece or a novelty. I strongly
suspect that such people have never heard a shot fired in anger
before.

Ah, the stumps. I remember the first time I got there, stepping

weed blowing down the main drag. "Oh my god; I have to stay
here for a YEAR?!" (This was before I became an officer.)
I wonder which part your cousin meant; perhaps Camp Wilson,
which is an active training area (and pretty much nothing else,
though there is a very small PX there selling pogey bait).

Almost all countries other than the United States limit freedom of speech
by excluding the incitment of hatred towards minority groups.
This is perhaps a natural result of Europe having had World War II fought
on its own soil, and so they consider it a matter of survival to prevent
the rise of another movement similar to Nazism.
Given current political trends in Europe, I have to say it's a pity they didn't think that one way to prevent the rise of bigoted extremist
movements would have been not to have such a liberal immigration policy
that the demographic consequences would end up being an annoyance to a lot
of ordinary people not previously inclined to bigotry.
Now, I took out one excessively elaborate header format, and restored a feature to the architecture that I took out when pruning header types,
but this time in a different form, associated with a different header
type.
And now I rearranged the headers a bit, to defragment their opcode
space.

California apparently banned the 60/40 lead/tin stuff IIRC, but still
allows people to freely possess lead-free solder (so people apparently
need to smuggle the 60/40 into CA if they want to use it). Everywhere
else, 60/40 is OK. Well, and CA has the "age verification" controversy,
etc.

The same is true in the US military. I always found it annoying
that I had to make space for my issued equipment at home, but
c'est la vie.
Personally, I have no military experience at all (not counting school
cadets). But one of my sons joined the National Guard after his
military service. He has a neat solution to problem of space for his
equipment - he keeps it in his old bedroom in our house, not in his own
flat :-)
Seems like your son should take his obligations a bit more
seriously: keeping his equipment at your house, when it's
supposed to be in his dwelling, sounds like a rules violation.
What's good for the goose is good for the gander.
It also means that there are less guns stored in
concentrated places as potential targets for robberies. And in the
event of a real invasion, it's a lot easier to smugle around and
distribute firing pins to service members than to pass around guns from >>>> a central armoury.
There are tradeoffs, however: it is also easier for a bad actor
to source a weapon by breaking into a private home.
It is plausible, but AFAIK it is extremely rare here. The solid
majority of criminals here don't want guns, and would probably not take
one if they found one in a house they were robbing. As a house burglar,
you can't easily sell a gun, you don't need one for defence, you don't
need one to threaten anyone - it just increases your chance of being
shot yourself, and increases your punishment if you get got. There are
guns in the more serious narcotics gangs, but those are handguns - they
have no use for military weapons.
FWIW, handguns are military weapoons.
My T/E weapons in Afghanistan were a 9mm handgun and an M4
carbine. I was embedded with an Afghan Army Unit, and was armed
pretty much at all time. This was at a time when we knew there
were Taliban infiltrators in the army. Indeed, I mentioned
working with UK forces: such an infiltrator threw a hand grenade
into a tent full of British soldiers, who were sleeping at the
time (this was in the middle of the night) and sprayed it with
fire from an AK-47, killing three and wounding several more.
That is to say, we were at a relatively low, but constant and
higher than baseline level of risk that most ISAF troops were
not subject to. Despite that, and despite being directly and
indirectly threatened myself on multiple occasions, I only
carried my pistol unless I was outside the wire.
We also don't really go in for shoot-to-kill in Norway.
Note that I'm talking about the use of deadly force to prevent a
bad actor from forcibly taking military-grade arms. That is
exactly the sort of thing that deadly force arguably _should_ be
authorized for.
There is a distinction (which I did not make, but should have) between
authorising deadly force, and encouraging it. As a last resort, it
makes sense in situations like this. But it should be very much the
last resort. Real-life criminals are not like in the movies - if
military guards point guns at them, they will put their hands in the air
and no one needs to be shot. (It's a different matter for criminals
high on drugs and unable to think rationally, but they don't try to raid
military armouries.)
Of course there, is a continuum of force, and despite recent
idiots in charge of the US military asserting otherwise, the
rules of engagement and the laws of warfare are taken _very_
seriously.
But the military are not the police. Full stop. If someone is
trying to attack a military armory with the intention of seizing
arms, they're not likely to be some petty criminal, but if they
obviously are, they will likely be subdued uninjured. The point
of mentioning that deadly force is authorized when protecting
those kinds of assets is to point out the relative value of the
assets themselves. To whit: weapons are dangerous, and in the
wrong hands, even more dangerous. They can, and should, be
protected.
Btw: as a veteran, one of the things that _really_ bothers me in
the US is when the police, in particular, refer to members of
the general public as "civilians". Words have meaning;
"civilian" refers to someone who is not a member of a military.
The police are are definitionally civilians.
If shots need to be fired, the primary aim should
be to persuade the bad guys to surrender, not to kill them.
Is it better if the enemy surrenders? Sure. But this idea that
you are going to shoot to wound in a combat scenario is not
realistic. As you said, it's not like in the movies.
But more broadly, from a military perspective, this doesn't make
a lot of sense to me, because it ignores the human factors at
play in the fog of war.
Due to the sympathetic physiological reaction to stress, one
tends to lose one's fine motor skills in a combat-type situation
and it can be difficult to remember even the most basic bodily
functions: lose of urinary and sphincter control are common,
for example (hence the expression, "scared shitless"). Moreover
long experience in human history shows that it is impossible to
know a priori how one will react: some people are ridiculously
calm in combat, others are not.
While I have (as I said) no military experience, I have a fair bit of
martial art experience - and what you describe is entirely correct.
Martial arts are art forms, like dance, not combat training.
I really wish people who study them would internalize that. You
get one good punch on the street; you are not experts on actual
warfare, lethal or otherwise. You should take care not to
extrapolate your study of an art form to things you have no
direct experince of.
Or you can listen to someone who's actually done it and who is
telling you that the intent (which yes, is explained to the
troops) is to demonstrate that we take all of this _very_
seriously, that human falibility means that people can and do
make mistakes, and that we build processes and procedures to try
and mitigate or avoid those mistakes.
Long experience has shown that mutual inspections are better
than relying on self-affirmation.

Only thoughtless people are calling it that. You've been watching tool much Fox News - a channel that describes itself as "entertainment"
without any obligation to tell the truth.
The freedom of innocent people not to suffer abuse, hatred and prejudice trumps the freedom of nasty little sods who think they have the right to abuse others. And inciting hatred or encouraging others to commit
criminal behaviour is just as much a crime in the USA as the UK.
Where corporations can lead search-and-seizure operations for claimed
IP violations;
No, they can't.
And in European countries, unlike the USA, corporations don't get to lie
and cheat then claim "freedom of speech".
We are free to live safely. We have the freedom to send our kids to
school without worrying if they will survive the day. We have the
freedom of knowing that we won't lose our jobs just because the boss is having a bad hair day. And losing a job does not mean losing our
health. And we have freedom to vote, knowing that votes count equally. (Well, the UK parliament elections still have a way to go here, but the Scottish and Norwegian elections have fair votes.)
No country is perfect by any means, but Europeans live far freer lives.
We might not have the freedom to own guns so our kids can accidentally
kill each other, but overall we win out.

OK.
Some people were making it sound like they were opposing peoples'
abilities to have and express opinions in general (though they didn't usually specify on what sorts of topics).
Originally, seemed like, it could have been something like, say:

Political leader sees it and feels insulted and has person arrested.
Or, something of this sort, ...
But, yeah, in the US people usually say the First Amendment guarantees peoples' freedom to have and express opinions about whatever.
Though, OTOH, I guess things like social media platforms still have the ability to ban people from the platform if they go around spreading hate-speech or similar.

Saw a thing not too long ago talking about how apparently Sega left some Nintendo devkits in an old office building, then abandoned the building,
and later the building owners sold off all the old junk that was left in
the buildings.
Story goes that the guy who bought up some of the old junk posted about
it on the internet, and then Sega + Nintendo + UK Police went in and arrested the guy and took all his stuff (then they released the guy, but
he didn't get the stuff back), because the idea was that him having the devkits was considered as theft of intellectual property.
Eg (finding a few videos talking about one of the incidents): https://www.youtube.com/watch?v=Sy9Eb8J0xGk https://www.youtube.com/watch?v=NU040CTdJI0

Where I am, solder is sold on Amazon or similar...
Had seen videos where people made it seem like solder was some sort of black-market contraband.
Looking around, apparently the restrictions were specifically on lead-
based solder though, rather than restricting all solder.
In the case of California, did see something not too long ago saying
that they were trying to get something passed to ban personal ownership
of 3D printers and CNC machines.
Though, I didn't see anyone else talking about this, so it seemed unconfirmed.
There is a lot more talking going on about the CA "OS age verification" bull, and now something saying that the US federal people are now
looking into something similar (groan, this has a risk to potentially
ruin open source and make everything suck...). Hopefully it goes the way
of past proposals for bans on OSS and RISC-V and similar, ...
So, not like US is exactly perfect either...

Then again, I guess a lot of the news I had seen had also been fed

Norway did not use to have any restrictions at all on tools, like knives/axes/scythes up to and including shotguns.
The current regulations have explicit exceptions for knife carry in
public plaes when those knives (or swords!) are part of uniform or traditional dress. I.e around May 17th it is perfectly fine to carry
large amounts of metal (mostly silver) through airport security, but
they might tell you that the silver-decorated knife should go in checked luggage.
Similarly, Scouts' knives are fine anywhere.
Regarding firearms the Norwegian regulations are still way less strict
than the UK, pretty much anyone without a mental illness or felony
record can legally own a handgun:
You just need to start by becoming a member of a local pistol shooting
club, then turn up regularly to practice using club guns (at least 10
times or more) over a year, then pass a police security vetting which
check for those mental/felony bans.
At this point you can legally buy something like a Glock or 1911 and get
the serial number on your credit-card sized ownership card.
If you are very active, then you can get separate permits for a primary
and spare gun for each of the competition classes you regularly compete
in, I know people with 10+ handguns in their gun safe.
However, unlike the US, there is absolutely no way to get either an open
or concealed carry permit unless you are military or police.
Any handgun you own _must_ be stored in a proper gun safe, in can only
be brought out for cleaning and to transport it to the shooting range.
During that transport, the gun cannot be in the front seat with you, it
has to stay in the trunk or back seat, unloaded of course, and still in
its carrying box.

traditional dress. I.e around May 17th it is perfectly fine to carry
large amounts of metal (mostly silver) through airport security, but
they might tell you that the silver-decorated knife should go in
checked luggage.
I were my sgian-dubh with my kilt. Despite the name, it's not very hidden. It used to be legal to have one in the cabin of planes in the
UK, as long as it stayed in your sock.
Similarly, Scouts' knives are fine anywhere.
Regarding firearms the Norwegian regulations are still way less strict
than the UK, pretty much anyone without a mental illness or felony
record can legally own a handgun:
You just need to start by becoming a member of a local pistol shooting
club, then turn up regularly to practice using club guns (at least 10 >> times or more) over a year, then pass a police security vetting which >> check for those mental/felony bans.
At this point you can legally buy something like a Glock or 1911 and
get the serial number on your credit-card sized ownership card.
If you are very active, then you can get separate permits for a
primary and spare gun for each of the competition classes you
regularly compete in, I know people with 10+ handguns in their gun safe.
However, unlike the US, there is absolutely no way to get either an
open or concealed carry permit unless you are military or police.
Indeed. And you have to keep them locked in a gun safe, which the
police can check at short notice.
Similarly, you can own a hunting rifle if you pass the hunting tests and
are vetted by the police.
Any handgun you own _must_ be stored in a proper gun safe, in can only
be brought out for cleaning and to transport it to the shooting range.>>
During that transport, the gun cannot be in the front seat with you,
it has to stay in the trunk or back seat, unloaded of course, and
still in its carrying box.
Basically, in Norway you can have guns for sport or hunting, but not for threatening or shooting people.
The gun laws in the UK are a lot more restrictive (after all, there's
not nearly as much scope for hunting in most of the UK). Farmers can
get shotgun licenses, but I think if you have a pistol for sport it has
to be kept at the pistol club, not at home. (I have not looked at the rules in detail, so I could be wrong or out-dated.)

How do people actually count gate delays, and how useful is it?
Different gates have different delays (obviously), so counting
an inverter the same as a three-input NOR gate (independent of
fan-out, even) seems to be a large simplification which may be
useful for a fairly rough approximation, but not that much better.
Or am I missing something?

Something similar to this actually happened, in Norway:
At one point, after establishing that all men could vote, it was
understood that this of course only meant men with a tie to the land,
i.e farmers, millers, blacksmiths, industialists etc.
In reaction, a group working to make voting rights really universal
bought up large tracts of worthless swamp/marshland and split it into
square foot parcels. Armed with a owership certificate for said plot,
you could not be denied your voting rights.
I've also seen this done in the UK as a way to protect land from
developers. A forest (or whatever land is to be protected) is bought
then parcelled up and sold to thousands of people. If someone wants to destroy the forest to build houses, factories, or whatever, they need to find all these owners and buy from each of them individually.

You can also buy a square foot of land to get a (worthless, but

There is the "standard" FO4 counting scheme where 1 gate drives
4 other gate inputs, and in this scheme, a D-type flip-flop was
2.5 gates of delay.
As one can guess, gates can be sized: as small as obeys the FAB
design rules, to <basically> as big as one can afford. Naturally,
as gates get bigger, they can drive bigger loads--BUT they also
present bigger loads to the gates driving them.
Conway figured out that the fastest way to "buffer up" a signal
was to use inverters staged in the ratio of 1:e:e^2:e^3... with
e being the standard 2.7... base of natural logarithms. Rounding
e up to 3 degrades speed by less than 1%, rounding up to 4 only
slows down 10% or so--so, most buffering is done at FO4, where
a minimum sized gate drives an inverter 4× as big which would then
drive another inverter 16× as big...
Each transistor between a power connection and the signal connec-
tion basically, adds its own transconductance to the electrical path (ignoring body effect). Knowing that deMorgan's laws apply; we
instantly see that a Nand gate is simply a Nor gate with inverted
inputs. A Nand gate has its serial string of FETs between signal
and ground and a parralel path from signal to Vdd, while a Nor has
its serial FETs between signal and Vdd and its parallel path between
signal and ground. To deal with these serial paths, the transistors
are lengthened; a 2Nand has N-channels 2× as wide and can use 1×
P channels, a 3Nand has 3× N-channels and still 1× P-channels, ...
{Nors are similar but reverse Ns and Ps} Somewhere along the line,
the parallel path FETs have to get lengthened because the capacitance
of all the serial path diffusion capacitance (to maintain rather
equal pull up and pull down).
Soon, one realizes that one needs SPICE simulation with accurate
models to push the edge--just like when pushing the Young's Modulus
in engineering models.
In fast designs, there is an entire team charged with buffering and
routing the CLOCK so that every gate in 10^2 mm^2 receives its rising
edge and falling edge with less than 1 gate of delay 'skew' across
the whole chip using wires that have more than 1 gate of delay when
jumping over 30 gates. CRAY-1 had less than 1ns of clock skew in a
machine the size of restaurant refrigerator using wires with 2ns/foot
of delay. In ASIC designs, we assume (starting out) that there will
be 1/2 clock of skew in the 'clock'

The part I don't see is the rules for combinatorial gates.
There also seem to be combinatorial gates like XOR or AND-OR-INV or MUX
where multiple gates are combined in one but at a lower gate delay.
For example, in TTL an XOR or a 2:1 or 4:1 mux has 3 or 4 gate delays
because it really is an INV, an AND and a OR,
but in CMOS those seem to be just 1 or 1.5 gate delays.
In CMOS sometimes one is able to smoosh gates together and eliminate
gate delays, but the rules for when smooshing is allowed are not
obvious to me. I just assumed that it all sorts out in SPICE simulation.
I find this makes it more difficult to just look at a CMOS logic circuit
and know whether it will fit within a 20 gate delay stage budget.

I got to visit the flight line in 2024, very interesting.
Cool.
Prior visit to a Marine base was at 29 Palms in the 1980s, visiting
a cousin. He was living on-base in married housing and told
me to avoid the well-lit compound several miles east of the housing area, which
was secured and managed by the NOP.
Ah, the stumps. I remember the first time I got there, stepping

weed blowing down the main drag. "Oh my god; I have to stay
here for a YEAR?!" (This was before I became an officer.)
I wonder which part your cousin meant; perhaps Camp Wilson,
which is an active training area (and pretty much nothing else,
though there is a very small PX there selling pogey bait).
I just looked on google maps and they've pretty much censored
the entire base in both the map and satellite views.

The same is true in the US military. I always found it annoying

Personally, I have no military experience at all (not counting school

Seems like your son should take his obligations a bit more
seriously: keeping his equipment at your house, when it's
supposed to be in his dwelling, sounds like a rules violation.
I don't know the details of the regulations, but I can assure you that
it is entirely within them. As a student, his flat is considered
temporary accommodation and our house is his permanent home. His
National Guard base is in our area, not where he is a student.

There are tradeoffs, however: it is also easier for a bad actor
to source a weapon by breaking into a private home.
It is plausible, but AFAIK it is extremely rare here. The solid
majority of criminals here don't want guns, and would probably not take
one if they found one in a house they were robbing. As a house burglar, >>> you can't easily sell a gun, you don't need one for defence, you don't
need one to threaten anyone - it just increases your chance of being
shot yourself, and increases your punishment if you get got. There are
guns in the more serious narcotics gangs, but those are handguns - they
have no use for military weapons.
FWIW, handguns are military weapoons.
Sorry - I meant pistols, rather than rifle-sized weapons. (Of course >pistols are also used in the military.)

Of course there, is a continuum of force, and despite recent

you are going to shoot to wound in a combat scenario is not
realistic. As you said, it's not like in the movies.
I think that there has been a bit of a disparity in the situations we
have been imagining. I agree entirely that shooting to wound in a
combat situation is not realistic. It just seemed to me that you were >suggesting armoury guards were moving to combat mode a lot more quickly

Just to be clear here - mutual inspections are fine and often a good

But let's get back to gate delays, please.
Let's.
How do people actually count gate delays, and how useful is it?
Different gates have different delays (obviously), so counting
an inverter the same as a three-input NOR gate (independent of
fan-out, even) seems to be a large simplification which may be
useful for a fairly rough approximation, but not that much better.
Or am I missing something?
There is the "standard" FO4 counting scheme where 1 gate drives
4 other gate inputs, and in this scheme, a D-type flip-flop was
2.5 gates of delay.
As one can guess, gates can be sized: as small as obeys the FAB
design rules, to <basically> as big as one can afford. Naturally,
as gates get bigger, they can drive bigger loads--BUT they also
present bigger loads to the gates driving them.
Conway figured out that the fastest way to "buffer up" a signal
was to use inverters staged in the ratio of 1:e:e^2:e^3... with
e being the standard 2.7... base of natural logarithms. Rounding
e up to 3 degrades speed by less than 1%, rounding up to 4 only
slows down 10% or so--so, most buffering is done at FO4, where
a minimum sized gate drives an inverter 4× as big which would then
drive another inverter 16× as big...
Each transistor between a power connection and the signal connec-
tion basically, adds its own transconductance to the electrical path
(ignoring body effect). Knowing that deMorgan's laws apply; we
instantly see that a Nand gate is simply a Nor gate with inverted
inputs. A Nand gate has its serial string of FETs between signal
and ground and a parralel path from signal to Vdd, while a Nor has
its serial FETs between signal and Vdd and its parallel path between
signal and ground. To deal with these serial paths, the transistors
are lengthened; a 2Nand has N-channels 2× as wide and can use 1×
P channels, a 3Nand has 3× N-channels and still 1× P-channels, ...
{Nors are similar but reverse Ns and Ps} Somewhere along the line,
the parallel path FETs have to get lengthened because the capacitance
of all the serial path diffusion capacitance (to maintain rather
equal pull up and pull down).
Soon, one realizes that one needs SPICE simulation with accurate
models to push the edge--just like when pushing the Young's Modulus
in engineering models.
In fast designs, there is an entire team charged with buffering and
routing the CLOCK so that every gate in 10^2 mm^2 receives its rising
edge and falling edge with less than 1 gate of delay 'skew' across
the whole chip using wires that have more than 1 gate of delay when
jumping over 30 gates. CRAY-1 had less than 1ns of clock skew in a
machine the size of restaurant refrigerator using wires with 2ns/foot
of delay. In ASIC designs, we assume (starting out) that there will
be 1/2 clock of skew in the 'clock'
The part I don't see is the rules for combinatorial gates.
There also seem to be combinatorial gates like XOR or AND-OR-INV or MUX
where multiple gates are combined in one but at a lower gate delay.
For example, in TTL an XOR or a 2:1 or 4:1 mux has 3 or 4 gate delays
because it really is an INV, an AND and a OR,
but in CMOS those seem to be just 1 or 1.5 gate delays.
A 4:1 Mux is a 2222AOI gate--one Ssllooww gate--but still 1 gate.
One slow gate is generally faster than 2 gates (and less power)
because only 1 signal has to move (Vdd->gnd or gnd->Vdd) instead
of more than one. Each signal moving is limited by the transcon-
ductance of the FET stack and the capacitance being driven. We
call the rise/fall time the edge speed.
In CMOS sometimes one is able to smoosh gates together and eliminate
gate delays, but the rules for when smooshing is allowed are not
obvious to me. I just assumed that it all sorts out in SPICE simulation.
Almost always be deMorganizing the logic.
I find this makes it more difficult to just look at a CMOS logic circuit
and know whether it will fit within a 20 gate delay stage budget.
If the gate delay count is less than 20, there is "some" sizing of
those gates which will result in minimum delay.

I am not sure what is DAZ. Does it abbreviate "De-normals are zero" ?
I.e. subnormal not only never produced as result of arithmetic ops but
also silently converted to zero when taken as input?
If that what DAZ means then I oppose it even stronger than FTZ.

I'm referring to where you merge gates together.
For example, an XOR is (A nand (not B)) nand ((not A) nand B)
which is 2 INV (4T) and 3 NAND gates (12T) with a total of
16 transistors and a delay of 3.
The 3 NAND can merge into a single gate of 8 transistors
and a total of 12T and a delay of 2.
Presumably this merging of gates can continue to some point
but what that point is isn't clear to me.
That makes it difficult to look at a logic diagram and
know how many gates are going to merge that way.

Yes but you don't get to merge gates together to shorten the delay.
You only get to choose from the packages available
and for most situations just scan the spec sheet and use
the max of the all propagation delays.

Realistically, anyone making a hobbyist class core can't make anything
like what you describe.
And, if doing it on an (affordable) FPGA, can only do what an FPGA can realistically manage. Which isn't even anywhere near the level of the
SoC that fits in a typical cellphone at this point.
more like late 1990s logic complexity at early 1990s clock speeds.
Well, and, for PCs, most people don't have 64 cores either...
Typical consumer-grade CPUs being more like 8 or 16 cores.
Also typical GPU FPUs are low precision (with trying to use "double" in
a GPGPU context often resulting in a fairly steep performance penalty).
For "enterprise" stuff, that is more "money to burn", which is a very different scenario.
Well, then there are NPUs, which seem to be going in a more "mixed FP8/ FP16" direction. But, doing FMA at "FP8*FP8+FP16" is also, a very
different situation.
Well, and if your task is mostly bandwidth bound, maximal FPU precision
is not the priority.
Even in my case, I am still left partly battling memory bandwidth walls (like, say, frequent use of FP8 or FP16 in my case not being about
trying to save RAM; rather trying to optimize for D$ and I$ and memory bandwidth and similar).
Which is ironic in a way, given that seemingly I am in a better place relative to memory-bandwidth compared with clock-speed vs a lot of
late-90s and early-2000s CPUs (well, because running a 16-bit wide DDR
chip at 50 MHz, isn't *that* drastically slower than a 64-bit wide SO-
DIMM running at 67 MHz from the early 2000s; or at least if comparing 50
MHz vs 1400 MHz for the CPU core).
Though, there is still the limit of what sorts of use-cases one can fit
into the limited precision of these formats.
...
Main problem case in practice (where differences between subnormals and
FTZ semantics becomes visible) involves dividing something by a value
very close to zero. This requires alternate handling to get correct

If you consider FDIV as having to get the rounding correct--that

-------------------
Not in the DAZ/FTZ mode, granted.
For the IEEE emulation mode, the idea is to try to patch things up as
needed such that FMUL is correct (similar to the matter of dealing with subnormal numbers).
But, yeah, the DAZ/FTZ mode may typically also give incorrectly rounded
FMUL as well as incorrectly rounded FDIV.
In both cases, the issue appears to go away though if the intermediate computations are done at Binary128 precision. But, this is its own pros/ cons thing.
So, for SIMD, I mostly ended up going with Fixed-RNE, DAZ+FTZ, and Two's >>> Complement FSUB, mostly because the alternative was poor even for SIMD.

Note: IEEE 754 delivers the right answer, BTW...
Yes, but I was pointing out mostly the problem of trying to cheap out
too much.
While for SIMD it initially seems like one can cheap out really hard,
basic integer arithmetic scenarios failing to give exact results, and a tendency for values to drift towards zero, can start to have fairly
obvious and visible effects.
So, there is a limit here...
It can escape notice if limited solely to graphics and audio tasks, but
as soon as one starts trying to use it for something much more demanding than pixel colors or audio mixing, it falls on its face.
One place it becomes obvious pretty quickly is if doing physics
calculations or rotation math, where objects' positions and rotations
will start to steadily drift. They tend to be adjusted every frame,
based on things like applying forces and time-steps.
If the objects all start slowly rotating and sliding towards the origin,
the suck is evident.
So, will need to draw a line here.

you had a shred of an argument, now you do not--we grew out of those
constraints.
Realistically, anyone making a hobbyist class core can't make anything
like what you describe.
with no FP. Strange thing, I could never get more than about 48 cores to work.
I think taking the target audience into consideration is important. If
one is trying to produce an example for a low-cost FPGA then there are limits to what can be done. Most people looking for starting-out type examples are not going to look at superscalar machines with FP ops. For
the more complex stuff people expect that larger, more expensive
hardware is required.
I think getting IEEE correct results does not use much more logic than simpler approaches. One is talking small percentages. What is the difference? Hundreds of LUTs in an FPGA with tens of thousands of LUTs available? 64-bit FMA is using about 3600 LUTs with sub-normals and rounding.
If one is not looking for IEEE compatibility there may be other
approaches to FP that might use fewer resources. Two’s complement representation?
There is the method of logical effort, see
https://en.wikipedia.org/wiki/Logical_effort . I have not made
much effort to do calculations using that method.
Yes, I haven't actually used it either.
Sutherland has examples of the gate merging I'm referring to.
Section 4.4 Asymmetric logic gates figure 4.3 has an example of
(A and B) nor C)
merges the AND and NOR gates so instead of 2 gates and 8 transistors
its 1 gate 6 transistors.
An alternative would be to use an actual library as an example.
A company called Nangate released an open-sourced library (google
for NangateOpenCellLibrary_typical.lib ), based on a 45 nm process,
for which delay calculations can be done as example, for example
using Berkeley ABC. That program can also do optimiztations
(although it cannot handle gates with more than one input, such as
full adders, and has weaknesses in stability). I haven't tried to
model wire delays with this.
A while ago I was rummaging about and found the individual gate
delay info in the open source Process Design Kit (PDK) files.
https://skywater-pdk.readthedocs.io/en/main/ https://github.com/google/skywater-pdk
In CMOS sometimes one is able to smoosh gates together and eliminate
gate delays, but the rules for when smooshing is allowed are not
obvious to me. I just assumed that it all sorts out in SPICE simulation.
AOI and friends also work in TTL, I believe.
Yes but you don't get to merge gates together to shorten the delay.
You only get to choose from the packages available
and for most situations just scan the spec sheet and use
the max of the all propagation delays.
In fast designs, there is an entire team charged with buffering and
routing the CLOCK so that every gate in 10^2 mm^2 receives its rising
edge and falling edge with less than 1 gate of delay 'skew' across
the whole chip using wires that have more than 1 gate of delay when
jumping over 30 gates. CRAY-1 had less than 1ns of clock skew in a
machine the size of restaurant refrigerator using wires with 2ns/foot
of delay. In ASIC designs, we assume (starting out) that there will
be 1/2 clock of skew in the 'clock'

I thought that some designs used intentional clock skew. If the
natural places to divide pipeline stages results in different
logic depths, a skewed clock would enable some stages to borrow
time from others (I think).
Perhaps this is not called 'skew'.
(I have also read that pipeline stage delay can be kept constant
and area/power traded with time, i.e., a normally longer stage
can spend area/power to reduce delay and a normally shorter
stage can save area/power by spending the delay slack.)

I had to toss out the feature I had briefly
added, of an alternate instruction set where memory operations were
aligned, so that paired short instructions without register restrictions could be included at 50% of the opcode space.
At the moment, I don't think that's worth the trouble.
In addition to adding the new header, I added some additional needed instructions to the alternate instruction set - and corrected a mistake
in it as well.

Indeed.
The basic load-store instruction set takes up about 75% of the opcode
space of 32-bit instructions.
Including pairs of short instructions, sharing a 32-bit word, takes up
about 25% of the opcode space of 32-bit instructions.
The trouble is, though, I need a few other things.
I needed 32-bit operate instructions and additional memory-reference instructions. In my current iteration, I squeeze them out of a few unused opcodes in the short instructions. I had to squash the operate--- Synchronet 3.22a-Linux NewsLink 1.2
instructions down to half the space I had been using for them to do this.
Operate instructions: about 1/128 of the opcode space; extra memory- reference instructions: about 1/64 of the opcode space.
Also, I wanted a header that took up 1/16 of the opcode space, as the preferred simplest way to call for variable-length instructions. I had two spare opcodes in the 32-bit load-store instructions, but I had wanted to hang on to them for one extra instruction. I finally decided to limit the destination registers for the load address instruction so I could grab
both opcodes.
Now I really have run out of opcode space as far as general 32-bit instructions are concerned. I had to toss out the feature I had briefly added, of an alternate instruction set where memory operations were
aligned, so that paired short instructions without register restrictions could be included at 50% of the opcode space. (That was because I didn't have a spare bit in the header for the type of code this would have been most useful with; of course, since an alternate instruction set is in a separate opcode space, I could still have it, just at a higher overhead
cost of requesting it for a block; it just was no longer worth having, or
so it seems.)

The Motorola 68000 and the 80386 had groups of eight registers. The IBM
360 had sixteen integer registers, but only four floating-point ones. Most RISC processors have 32 registers.
Traditional processors had instructions that performed an arithmetic operation from memory into a register. RISC processors do arithmetic only
in registers, with operations to load and store from memory.
The System/360 addressed memory with a base register and an index register
in addition to a 12-bit displacement. Most microprocessors use 16-bit displacements, but usually only let you use one register with it.
I've tried to encompass all the features of these different processors as much as I could.
Accessing variables in arrays needs an index register for which element in the array is being accessed, and a base register in addition to the small displacement in the instruction.
I felt I couldn't leave _that_ out.
But every other modern architecture decided that they didn't need
separate base registers. Do you think they were wrong? Having them
doesn't save you anything - you still have to add to a register to
increment the element number. In fact it costs a little in the hardware
as the addressing requires two adds (Base+index+displacement) versus one (index + displacement). And it uses up a register needlessly. So why
include it?

It's true that address calculation, especially for multi-dimensional
arrays, involves extra steps.
Base-index addressing doesn't force two additions every time; one chooses whether or not an instruction is indexed.
But when one is referring to an array element, it saves adding the displacement either to the address or the base value by means of an
explicit add instruction. One doesn't save a register by not having indexing. One is still used to contain the modified address.

How do you count "most"? There are a lot of AMD64 processors that

But every other modern architecture decided that they didn't need

The S/360 does not have separate base registers.
One might consider the FS and GS registers of AMD64 to be dedicated
base registers. AFAIK FS is used for thread-local variables in some
OSs. But for single-threaded code, I have never seen any compiler use
FS or GS, and have not seen any assembly language program (other than
those for demonstrating their existence) use FS or GS, either. So
there seems to be little need for separate base registers.
Concerning addressing modes that involve GPRs, there are a lot of
statistics around about their use, and you can make your own
relatively easily by observing the usage of addressing modes on AMD64.
Note that for some registers, AMD64 requires the use of a displacement
even if it is 0 (that's because the encoding that one would expect for
the displacementless use of these registers has anoter meaning).

Index registers were considered a good idea back when they were originally introduced. It meant you could redirect an instruction to point somewhere else without modifying the instruction in memory.
Base registers became a necessity once computer memories got so large -
over 64K locations or thereabouts - that it wasn't practical to put whole addresses in instructions.
So the base register, although it works the

register might be incremented once per loop, while base registers are left alone.
So accessing an array requires one basically to copy a base register value into another register, and add the index to it.

Not goals exactly, but constraints. Remember, S/360 had no memory
address relocation hardware such as a hardware base register or paging.
The addresses in a program were real memory addresses. Thus address say 1,000 in a program was real memory address 1,000. So absent base
registers, you couldn't have more than one program in memory at the same time, since program1's address 1,000 would have referred to the same
real memory address as program2's address 1,000.

It was a product of the times. We've advanced well beyond
that in the intervening half-century.
Really, the 360 operating

with the contemporaneous competition.

The earliest incarnations of such were often not 'registers' per-se, but rather reserved locations in memory (c.f. PDP-8 'TAD I'). The Electrodata 220 had a 'B' register - the predecessor Electrodata 205 was the first commercial computer to offer an Index register (with the idea inspired
by the Manchester Mark I).

Modern CPUs, and I presume your design, use paging to allow multiple occurrences of the same address (in different programs) to refer to
different real memory addresses, thus don't need to specify a base
address in every memory reference instruction.

Actually, that conclusion isn't quite right. This would work for a CPU
like Intel's 432. But I intend programs to be able to work with large
linear address spaces bigger than 64K, bigger than the displacement field
in an instruction. That means a base register is still needed despite hardware paging features being potentially present.

You simply load the starting address of the array into an index register

I can believe that.
Given base+index+displacement there are never any support instruc-
tions in memory access. Given displacement can be {16-bits, 32-bits,
or 64-bits} all of memory is accessible in a single instruction...
Yes, but adding the specification of a base register takes instruction
bits away from somewhere else, typically the displacement. So the
S/360s choice to use them reduced the displacement to 12 bits. So
larger programs required use of multiple base registers,
which required loading them, i.e. extra support instructions, and increased register pressure (though with the availability of storage to storage
instructions, that was less of an issue)
ALWAYS !! This gets rid of another 3%-ish of instruction footprint
tipping the balance from 6%-ish (average of above) to 12%-ish (with
these additional savings, tipping the balance towards "put it in".
Then why did just about every modern architecture, including your My
66000, omit them?

Actually, that conclusion isn't quite right. This would work for a CPU
like Intel's 432. But I intend programs to be able to work with large
linear address spaces bigger than 64K, bigger than the displacement field
in an instruction. That means a base register is still needed despite

Most? Only the MIPS descendents come to mind. Most of these
architectures have been cancelled (MIPS, Alpha, Nios2), only RISC-V
survives.
Other than that, most architectures support at least [reg+reg]
addressing. I think that adding that addressing mode to the load instructions of these architectures would have been a good idea while
still staying within the 2R,1W register access limit that the
architects seem to have observed. A disadvantage of treating loads differently from stores would be that the decoding and the data path
would be different. The benefit would be that for a loop like
for (i=0; i<n; i++)
a[i]=b[i]+c[i];
the loop body could look as follows:
loop:
ld r1,(r2+r3)
ld r4,(r2+r5)
add r6=r4+r1
sd r6,(r2)
add r2=r2+8
blt r2,r7,loop
while typical RISC-V code has two additional adds in the loop because--- Synchronet 3.22a-Linux NewsLink 1.2
it has to update the cursors into b and c on every iteration.

And then we got ASLR, and now we have to live in a world again where
the code and the static data don't live in fixed locations.
So accessing an array requires one basically to copy a base register value >> into another register, and add the index to it.
No. Do you think that current CPU designs require that? They do not.
You simply load the starting address of the array into an index register >and add to that as needed.
In the general case (i.e., when the array index is not the counter of
a counted loop), instruction sets like MIPS, Alpha, and RISC-V need additional instructions for computing the address of the array
element, and only then use a load or store instruction to access the
element. However, these architectures are three-address
architectures, so the starting address of the array does not have to
be copied first in this process.
- anton--- Synchronet 3.22a-Linux NewsLink 1.2
According to Thomas Koenig <tkoenig@netcologne.de>:
Not goals exactly, but constraints. Remember, S/360 had no memory
address relocation hardware such as a hardware base register or paging.
The addresses in a program were real memory addresses. Thus address say >>> 1,000 in a program was real memory address 1,000. So absent base
registers, you couldn't have more than one program in memory at the same >>> time, since program1's address 1,000 would have referred to the same
real memory address as program2's address 1,000.
Small quibble: This depends on what your loader does. IIRC
(I would have to re-read John Levine's book on linkers and loaders
You rang? I don't think my book said much about it, but on OS/360 and its descendants, load modules are relocatable and when they're loaded into memory,
which they call program fetch, the addresses in memory, which they call address
constants, are relocated to wherever the module is actually loaded. If you have
three copies of a program running at once, they'd be loaded and relocated to three separate places.
The main motivation for base+displacement was that they both wanted an architecture with large flat addresses, and they needed compact instructions since memory was expensive and the small models would have only 8K or 16K.

Thank you. That is another constraint that John's design doesn't have

Why don't you just use an index register like just about every other architecture (except S/360 derivative) systems do?

I want an architecture with large flat addresses.
It's true, though, that the original System/360 had an _address space_ of
16 megabytes, and while you could get 16 megabytes of RAM for some high-
end models, it had to be slow 10 microsecond memory, the regular 2 microsecond memory for those models was only available in smaller sizes...
and today, a computer will often have 16 *gigabytes* of memory.
So since we have so much memory, what's the problem with using 64-bit addresses in every memory-reference instruction?
I haven't noticed anybody actually doing that. Not x86, not SPARC, not PowerPC, not Itanium, not ARM. Maybe I haven't been looking?
I figured that if we had more memory, that meant we were writing bigger programs - or programs that used more data, and so we had more memory to *use* but still no memory to *waste*.
However, I'm not _dead_ set against larger displacements. IBM's z/ Architecture, the 64-bit development of the venerable 360 architecture, offers a set of 48-bit instructions which use 20-bit displacements instead of 12-bit displacements. I have included 20-bit displacements as an option within Concertina II, since I took this as "evidence" that 20-bit displacements were genuinely - or at least _possibly_ - useful. Anything *short* of a 64-bit displacement (well, maybe 36 bits or 48 bits, since physical memory is still less than what a 64-bit displacement covers)
still needs a base register, so that includes 32 bits.
I haven't seen ISAs out there that use displacements larger than 20 bits
to any great extent, although absolute addressing without a base register
is sometimes offered in some architectures... as an exotic option. Such instructions, for example, may allow a computer to perform some exotic housekeeping tasks prior to loading up the base registers.
If I don't already have absolute addressing in Concertina II at this time,
I probably will get around to adding it - but it will _not_ be intended as the main addressing mode to be used for writing everyday real programs. It will be a special-purpose addressing mode, intended to make certain highly specific tasks easier to accomplish.

Since just about every architecture uses displacements that are smaller
than even 36 bits, let alone 64 bits, the option isn't "just use an index register", the option is "just use a base register". I can fiddle with the register to make it _also_ perform the function of an index register as well, but it _must_ perform the function of a base register because the displacement can't access all of memory.
Now that this point has been clarified, I'll try to answer your question.
The 68020 added base-index addressing with 16-bit displacements, but
because that mode was a latecomer, it took up 48 bits.
That's a _tiny_ bit of evidence that this mode is of some use.
But why?
- I admired the System/360.
- I assumed that page tables weren't going to make base registers
obsolete.
Even if nobody needs a code segment bigger than 64K, one still needs base registers to access *data*, which often is bigger. (You only
need the index register only if your program has only one array, at least
if you're coding the program in a naive fashion.)
- And your program may call re-entrant system routines that are away off
in the low memory where the operating system lives.
Since I'm designing a general-purpose CPU, I am *not* imposing the rule
that an operating system MUST use page tables to isolate every running program in its very own address space.
Some operating systems just used memory _protection_ mechanisms, not address renaming, to protect different users from each other.
Why would I _impose_ just one model, just one method, of writing an operating system on everyone? Wouldn't that make my CPU gratuitously
narrow, confined to one particular kind of use, for no good reason?
Now, that reasoning may well be - as I am guessing that you think from
what you have been writing - badly flawed.
Maybe anything that preceded OS/ VS in the 360/370 space is now so obsolete as to be strictly of historical interest only, and no one in their right mind in the present day would
write an operating system that _didn't_ stick different users in their own address spaces.

There's also LA, load address, which you could use with a zero base

used all over the place.
You could also use LA N,123(N) as an
immediate add of 123 to register N so long as you knew the result
would fit in 24 bits,
I gather they did a lot of simulations during the 360's design so
they presumably thought those were the useful immediate operations.

The reason for "just one model" is so you can virtualize OSs into
GuestOSs without the OS knowing it is being virtualized. For example
there is only 1 My 66000 instruction with any notion of privilege.
Everything else is page table access rights.
JCL was an attempt at minimizing the code path from card reader to
running application. By and large, the minimum code path has become irrelevant, and we benefit from the OSs providing much better

Yes, normally they wouldn't be needed there, since in that code, 48-bit instructions can be expressed in just 48 bits. But those existing 48-bit instructions require prefix bits to distinguish them from the regular

And, of course, in the event that I ever do define any instructions in
this category, I could always define a new header format in which a particular combination of bits in a prefix field indicates that the
16-bit zone to which it corresponds contains the start of a 48-bit instruction and not one of any other length, which would then give them
the right to be called 48-bit instructions.

My fetch unit paper design reads an 8-byte fetch block each clock
into a 32 byte circular prefetch buffer. The parser rotates the whole
32 byte buffer to align the instruction start with the length parser,
and a PLA examines the first 12 instructon bits to get the length.
It then validates that all the bytes are present in the buffer
and passes the 1 to 12 bytes + IP virtual address to the Decoder board.
This can do a sustained 5 MHz parse of 1 variable instruction/clock,
provided it hits the instruction cache. As most instructions are simple
and take 1 clock to execute, it should do sustained 5 MIPS.
Remember the 780 was 5 MHz but only executes at 0.5 MIPS.
It might also fit onto the same size PCB as the 780 used, about 15" x 15", >but requires more edge connector pins for more buses (~300).
On a separate board Decode will store the fetched instruction and
feed it through a bank of PLA chips, which controls tri-state buffers
to route signals into the Decode uOp output register.
If built my Fetch and Decode units could run 10x the speed of a 780,

The instructions are byte granular, variable length from 1 to 12 bytes long. That is long enough to hold a 4 byte instruction specifier (opcode + registers)
plus 8 bytes of immediate data. I expect the average instruction to be ~3 bytes.
My fetch unit paper design reads an 8-byte fetch block each clock--
into a 32 byte circular prefetch buffer. The parser rotates the whole
32 byte buffer to align the instruction start with the length parser,
and a PLA examines the first 12 instructon bits to get the length.
It then validates that all the bytes are present in the buffer
and passes the 1 to 12 bytes + IP virtual address to the Decoder board.
This can do a sustained 5 MHz parse of 1 variable instruction/clock,
provided it hits the instruction cache. As most instructions are simple
and take 1 clock to execute, it should do sustained 5 MIPS.
Remember the 780 was 5 MHz but only executes at 0.5 MIPS.
It might also fit onto the same size PCB as the 780 used, about 15" x 15", but requires more edge connector pins for more buses (~300).
On a separate board Decode will store the fetched instruction and
feed it through a bank of PLA chips, which controls tri-state buffers
to route signals into the Decode uOp output register.
If built my Fetch and Decode units could run 10x the speed of a 780,
using the exact same parts but just designed from a non-microcode
point of view.

Interesting that you got this to work at 1 IPC. And, as the Skymont
shows, with enough resources such an instruction set can be made to
work at 9 IPC (the decoders of the Skymont are 3x3 wide, the renamer
is 8 wide).
Still, the question is how much, if any, code density advantage this
provides over something like RV32GC. In any case, given that RV32GC
code is smaller then VAX code
<2025Mar4.093916@mips.complang.tuwien.ac.at>, the code density of
RV32GC should be good enough, and the decoder may then need less
circuitry. I expect that your approach also gives some advantage in work/instruction, especially over RISC-V.

The design is for the Fetch and Decode stages, and it is a paper design.
But those two stages each fit in a single pcb and would run at 1 IPC.

The high usage integer operate instructions fit have a 12b opcode
and 3 x 4b register fields. A 4B instruction would waste 1B each.
In 1975 memory was so expensive I didn't think that would go
down well with customers.
Also having immediate values avoids
all the risc constant pasting instructions.

Yes, that's why I mention it.
The problem is that as the # of pins goes up, so does the insertion friction.
At some point, which I don't know, the insertion force is high enough that
it can exceed the crush strength of the connector contact.
The contact gets crushed into the bottom of the connector and it is
useless.
On a bus like a PC bus where a card can go in any slot,
you would (hopefully) just move to another slot.
But on a backplane design like the 780 where cards must go in
specific slots, you just trashed your whole backplane and now
have to disassemble the machine to replace it.
There are connectors called Zero Insertion Force connectors
where you put the card in, then twist a screw or something and
the connector closes like a clamp on the card contacts.

This paper measured the 780's performance by making microcode histograms
of running programs. In one table it says the integer multiply and divide were handled by the same subsystem as floating point instructions.
https://people.csail.mit.edu/emer/media/papers/1984.05.isca.vax.pdf
Adding to the confusion, there was an optional floating point accelerator which presumably added hardware to do what used to be done in microcode,
but they don't mention that at all.

I am not an expert, but it seems to me that 120 extra pins on the
inter-board connectors would cost about as much as 120 pins of regular (socketed) chips per board. So if EricP can eliminate that many chips
or maybe a board, the cost should be the same. If not, it would be a
few percent higher. In absolute numbers, I expect that the increase
in cost would be <$1000.
The other question, of course, is, how much DEC could have charged for--- Synchronet 3.22a-Linux NewsLink 1.2
a machine that is 10x faster than a VAX 11/780. I guess that they
could easily have recouped the additional cost, if any.

The problem is that there is no sharp boundary between 16-bit and
32-bit code (whereas there is a sharp boundary between 32-bit and
64-bit code).
You can execute code from a 32-bit code segment, and then you get
operand size=32b by default (no-byte instructions work on 32 bits),
and address size=32b (32-bit address registers and the newfangled
addressing modes, including those with SIB) by default.
But you can use a operand size prefix, and your instruction will work
on 16-bit units. I expect that lots of "32-bit" code uses the operand
size prefix, e.g., for implementing Java's short type.
And you can use an address size prefix, and you will get 16-bit
address registers and the 8086 addressing modes (and 8086 addresing
mode decoding).
And you can execute code in a 16-bit code segment, where operand
size=16b by default and address size=16b by default (and the
addressing modes are those of the 8086). There you can use the
operand-size prefix to use 32-bit operands and the address-size prefix
to switch to 32-bit addresses and the newfangled addressing modes.
Let's assume that x86s would have disabled 16-bit code segments and
the address-size prefix. Given how easy it was to use these features,
can we guarantee that there is no OS and on program that is still of
interest that does not contain such stuff?
And how much would eliminating those features save?
They managed to--- Synchronet 3.22a-Linux NewsLink 1.2
put it into the 386 with 275,000 transistors. Ok, these days you have decoders that can decode 3x3 instructions per cycle, but still, the
reduction in size or complexity is probably not that great.

I saw that and was kind of surprised. I don't know when I first heard this,
but
it was widely believed that the 780 was about the same speed at a 370/158 which
IBM said was 1 MIPS. The obvious implication is that VAX did twice as much work
per instruction as a 370 which is not implausible. So depending on how you define MIPS, it's not strictly false.
How did I know that and people at DEC not? Maybe they needed to get out more.

My fetch unit paper design reads an 8-byte fetch block each clock

This can do a sustained 5 MHz parse of 1 variable instruction/clock,

To answer your second question first,
I have 3 instructions that must be sized at 1 instruction granule,
which in this case is 1 byte, as can occur on arbitrary boundary:
ILLG Illegal is opcode 0, causes an Illegal instruction fault
NOP No Operation
BRKP Breakpoint
ILLG is used pad non-executing space, NOP pads executing space,
BRKP can be deposited by a debugger at any instruction start.
Other instructions may be 1 granule, only these 3 must be.
The goal of my exercise was to see if Fetch and Decode units could
be designed with circa 1975 TTL that execute at 5 MHz getting 1 IPC.
The ISA is just a prototype to set some boundaries for the
Fetch and Decode designs have something fixed to shoot for.
The Fetch unit cares little what the internal format of an instruction is.
It only looks at most at the first up to 12 bits to determine length.
It only cares how many bytes are in the instruction and are they all
present in the prefetch register. If they are Fetch copies them to
the Decode input instruction register.
internal instruction of instructions and translates them into a uOp.
Provided Fetch and Decode meet there performance goal,
the instructions and their formats would be chosen such
that they are compatible with any limitations on those units.
The ISA is 32 bit integer and virtual address space.
Instruction Pointer register,
16 x 32b integer registers, 16 x 64b float registers.
No integer condition codes.
I wanted variable length instructions so it could have large immediates.
12 bytes was large enough to hold a 4B opcode and register numbers
with an 8B immediate that is either 1 fp64
or 2 int32 for compare and branch.
The Fetch unit parser uses a Signetics 82S100 FPLA to determine
the instruction length. The 82S100 has 16 inputs, 8 outputs,
and can match 48 product terms with 0, 1 or x dont-care bits.
The parser feeds the first 12 bits from the first 2 bytes plus
their 2 byte Valid flags and an error signal into the 82S100.
There is one input spare for future use.
The PLA outputs a 4b length from 0 to 12, plus 2 status bits
indicating the length is valid, or fetch unit stalled,
or fetch error, either page fault exception or HW error.
If the parse length is valid then fetch checks that all the
bytes of the instruction length are also valid.
If they are it passes the instruction to Decode input register.
To give an example, to encode the 3 1B instructions I define
(0 matches a 0, 1 matches a 1, x = a dont-care bit):
ILLG = bxxxx_0000_0000
NOP = bxxxx_1000_0000
BRKP = bxxxx_0100_0000
spare = bxxxx_1100_0000
Notice bits [5:0] of all are 0. So I define a PLA pattern
that matches that and spits out the length 1
11
1098_7654_3210
xxxx_xx00_0000 => 1
Now I want low usage frequency instructions like SYSENTER, SYSEXIT
that have no registers but I don't want to use up all my primary
byte code space so I continue in the second byte.
11So, Mil-like
1098_7654_3210
0000_0010_0000 => 2
Now I want 3 byte instructions for the high usage 3 operand instructions
like ADD, SUB, AND, OR, etc. with 3 x 4b register fields.
There are many of them, lets say 64 or 4 groups of 16.
11
1098_7654_3210
xxxx_xx01_0000 => 3
So all of the integer and float 3 register instructions begin
with the bits [5:0] = 01_0000, and bits [11:6] select individual instructions.
Now I go back and define exactly what those instructions are:
ADD Add Rd1 = Rs2 + Rs3
ADDFS Add fault signed overflow Rd1 = Rs2 + Rs3
ADDFU Add fault unsigned overflow Rd1 = Rs2 + Rs3
SUB Subtract Rd1 = Rs2 - Rs3
SUBFS Subtract fault signed overflow Rd1 = Rs2 - Rs3
SUBFU Subtract fault unsigned overflow Rd1 = Rs2 - Rs3
...
Now I'll do conditional branches.
Conditional branches need a 4b register to test,
a 3b condition code to test for (EZ = equal zero, NZ = not zero, ...)
and either a short byte or long 32b word offset.
But wait... a 12b opcode, 4b register and a 1B offset
is a 3B instruction so I can take all the short conditional
branches and merge them with the other 3B instruction groups.
That leaves long branches which have a 12b opcode, 4b register,
and 4B offset and a length of 6 bytes.
11
1098_7654_3210
xxx0_0011_0000 => 6
But wait... a 12b opcode, 4b register and 4B immediate is the
same length as an ADDIW add immediate word with a single
source-dest register. So I make the long branch group bigger
by moving the dont-care point:
11
1098_7654_3210
xxxx_x011_0000 => 6
and now define all those instructions.
And so on.
There are connectors called Zero Insertion Force connectors
where you put the card in, then twist a screw or something and
the connector closes like a clamp on the card contacts.
I did a quicky search to see if there were anything like what
I need, just to get the price, but could not find anything.
If they exist I imagine they are considerably more expensive
but each cpu only needs 25 of them.
