Not that you've got any intention to solve the problem (I don't think
you can solve it) and you just want to be a dick as usual, still, I add
for others who may be interested, that the point you're making is the
business of missile's own software, and not this problem. Missile itself
computes the point at which it can get just early enough and explode so
the damaging effects would reach all five targets by the time t and at
those five locations that the targets are, as given above.

So we don't have to change the problem to adjust for that consideration.

Now jump back in the bag where you've been for a few years now.

And to others reading it, I add a few spoon feedings:

- It's a straightforward programming problem, well within capabilities
of Code Monkeys, but you need to first solve the problem, and it
requires simple math at the college algebra level.

- three skills are tested here:

1- knowing the simple math
2- solving the problem
3- programming it

I doubt the #2 skill above can be found in many Code Monkeys. A Code
Monkey generally cannot solve it. So that's the heart of the problem,
and if you solve it you're above a Code Monkey in programming.

AFAIK, this is a very difficult problem.'

But algorithms have recently been developed. The best one is, of
course, implemented in FOSS:

When I get some free time I may try it out.

As someone that has actually spent several years dealing with
anti-aircaft missiles all I can say is that you haven't a clue how
either the intercept equations or warheads work.

This is just your usual Dunning-Kruger babbling nonsense.

It is a set of three dimensional differential equations that depend on
the current position and velocity of the missile and the target.

The equations have been well known prior to 1945 and originally
were solved in real time by purpose designed vacuum tube analog
computers.

See the history of Project Nike, officially formed on 8 February 1945.

Like most other math or physics problems, one can solve it in very
difficult ways too :) Hehe :)

Question is, can you solve it by using nothing other than at most
college algebra! No PDE's. No calculus. Just simple college algebra math.

This "Miniball" is interesting though :) But heck, I solved it myself
two minutes before concocting the blog post. It took me about half an
hour of looking into various approaches to it. That was half an hour of
fun that rBrown (future rBowman, after his descendants become brown in
the USA) doesn't understand and therefore does not enjoy.

I don't post anything in this blog for which per-written software would
be required.

Since the intercept problem requires the solution of three dimensional
differential equations, no.

You can not solve a problem you do not understand and it is blazingly
obvious to anyone that has even a little experience in solving intercept
problems that you haven't a clue.

The slight modification of time t in the statement of the problem to
shut up smart aleck dickheads about latency in arrival of explosion
effect, would be this:

1- what would be the coordinates of the point in the sky, that the
missile with the weakest warhead needs to explode at, at time (t
-delta), to damage all those 5 fighter jets critically enough, by the
time t?

2- within what maximum radius of that explosion, any fighter jet would
get critically damaged by the time t?

Delta is the time required for damaging effects of the explosion to
reach all five jet fighters by the time t. It is determined by the
missile's own software and is not part of this problem.

I should look at the source to see if they're using the method I used,
cause my way might be in fact novel. Perhaps thousands of times faster
to compute than how they're doing it.

I actually got the answer to this problem by hand calculations. A
program would make it faster of course, but the method is fast enough
for 5 points to just apply by hand.

If I look at those sources, and find out they're doing it the much
harder way, then I would not only want "good money" to disclose my
method, but will want "big money" for it :-)

All the crap the likes of "Pennino" sold to military in this country in
that regard, would get modified accordingly and improved.

I would want big money, paid to my dick alone!

Unless all the aircraft were within a radius of a about a hundred
meters and the missile warhead was nuclear with a yield of around 30 kt,
there is no solution.

FYI the largest nuclear warhead on an anti-aircraft missle had a yield
of 28 kt.

> 2- within what maximum radius of that explosion, any fighter jet would
> get critically damaged by the time t?

If the missile had about a 30 kt nuclear warhead, then any aircraft
within about a little over 100 meters of detenation would be destroyed.

If the aircraft was more than a little over 100 meters from detenation,
then any aircraft heading toward the detenation would be destroyed and
aircraft heading away from the detenation would be essentially
undamaged, though the crew would likely die from radiation some time
after finishing their mission.

The above is utter gibberish.

You have no clue on how any of this works.

FYI the only anti-aircraft missiles ever designed to take out more than
one target at a time had a nuclear warhead.

FYI the shock waves of conventional explosives and nuclear explosives
both travel at roughly MACH 1.

FYI fighters have been capable of exceeding MACH 1 since the 1950's and
thus can outrun an explosive shockwave of any kind if they are going away
from the detenation point at the time of detenation.

FYI the maximum radius of a 30 kt nuclear warhead fire ball is about
100 meters.

FYI missiles with conventional warheads are designed to detenate within
a very close range of the target, i.e. a few feet, or actual contact.

Like I said, you have no clue on how any of this works.

Since the entire world has been working on the problem since about circa
1943, I highly doubt a Dunning-Kruger poster boy that has no clue of the
issues involved has anything what so ever to contribute other than
nonsensical babble.

If the warhead explodes at time t, the shock wave can only spread outward
at the speed of sound. Thus any blast effect would be well past t.

However, if the warhead was a nuke, the blast wave would still be limited
to the speed of sound but other EM effects, such as X-Rays, would travel
at the speed of light. Intense X-Rays could potentially incapacitate the
pilots and EM effects could fry the aircraft circuitry -- all at time t.

However, Mr. Pennino also has valid points.

I still do not understand your problem and that is why I jumped immediately
to the "minimum enclosing sphere" solution, which would work for a nuclear
warhead designed for radiation kill.

Since I have actually dealt with anti-aircraft systems for years as

do.

Radiation takes a while to kill, by which time the pilots will have
finished their missions.

To be effective, anti-aircraft weaponry must immediately either damage
the aircraft enough to be unusable or incapacitate the crew.

Hehe ;) I didn't suggest it as a physics problem (that's another blog
that's still essentially ongoing with a different subject header).

If the physics of it sounds non-practical, then so be it. Just forget
it. Or as you suggested make the warhead a nuke and the damaging factor
the EMP.

It took Physfit just half hour to solve as well as code the problem,
then Houthis updated their Missile's software to use that subroutine to
aim at a point other than directly where any fighter jet would be. This
worked pretty well for them, and after the Nazis lost a few fighter jets
too many, they backed off like Bill Gates had backed off from the
scenery down the Mossberg barrel,

Nazis: "Those Houthis now hit us five at a time??... FUCK _ME_!"

After Nazis were gone, Physfit looked around to study the place a bit
better and perhaps even find a healthy restaurant of some sort nearby to
eat at. He was still very hungry and did not remember when it was he
last ate. So he could push it a little bit and assume that at least 48
hours had passed since.

Then while looking out the window,,, what do you know... he saw a Long
John Silvers right there across the street!...

"Long John Silvers in Yemen?" he asked the same Houthi he'd talked before.

Houthi: "Fish is Halal meat as you know, The franchise owner is a
Houthi himself. We beheaded the earlier Nazi owner of the store. No
infidels there now. So we often dine there."

Physfit: "Good job! Is there anything strange about their menu prices?"

Houthi: "Strange? No. The prices are reasonable."

So Physfit decided to go for a three fish fillet with huge coleslaw
treat. He left the well camouflaged compound and entered the open space
where he met the type of Sun one gets in Yemen for the first time in his
life. It beat the Texas Sun something like 5-fold. But he still pretty
well remembered the technique he and his elder brother had discovered to
deal with Sun's punishments like that under Tehran's hottest days' Sun*.

Se he put that experience into use and it worked. All he needed to do
was to reduce the stress all over the body as he walked rather slowly,
especially paying attention to muscles around the eye and the eyelids.
To adjust the light, without forcing it one bit, he allowed the eyelids
to come down just enough to let the right amount of light inside the
eyes, and carefully making sure no muscle around the eyes were flexed in
any way to keep the eyelid just there.

In that way he crossed the distance from the compound to the store
without even sweating. Mighty trick they'd found, he and his brother, in
that hot day in north Tehran, early in 1970s.

Inside store was cool and comfortable. He went closer to the order area
to take a look to see if they had a similar order of three fish fillets
with a huge side of coleslaw, as in the nearest store in Dallas.

Physfit: "Ahh Holy Crap. Not again..."

Prices were expressed not only in base e instead of 10, they were also
presented in nested radicals!... some finite, and some even with
infinite nested radicals. He searched and found the three fish fillets
with a huge side of coleslaw and ordered it. The Houthi cashier asked in
Arabic for some amount of Yemeni Rials.

"He must think I'm Arab", Physfit thought.

Not knowing the Arabic language, he looked at the price on the register
machine but found that also expressed in nested radicals, so he just
produced his wallet and took all the bills out and strangely enough
found them in Rials. He handed all the bills to the cashier. Cashier
took what he needed and gave the rest, together with the receipt, back.

The price on the receipt looked like this: (in base e)

_____________________________________
╱ ____________________________
╱ ╱ ____________________
╱ ╱ ╱ _____________
╱ ╱ ╱ ╱ _______
╲╱ 2 + ╲╱ 2 + ╲╱ 2 + ╲╱ 2 + ╲╱2 + ...

While waiting for the order to get ready, he decided to calculate that
number. Soon order was ready and he had found the price as well, in base
e. Price looked rather reasonable although he didn't know the conversion
rate of Rial to Dollar.

He enjoyed his meal tremendously, then stood up and walked outside in
the Sun, and began going back to the compound. The damn meal tasted even
better than the ones in Dallas.

What was the price in base 10 in Dollars?

Physfit didn't notice that the enragingly intense Sunlight was now soft
and the beautiful sky even had several chunks of clouds in it. He passed
the street and began walking towards the compound.

It took more than what it should have, so he took a good look around to
see if he missed where he was to turn left. But it didn't look like
anything like what he had seen around him from corners of his eyes while
carefully walking toward Long John Silvers an hour or so ago. In fact
nobody was around now. The store was still there, about 500 years away,
but other than trees and knee-high grass on the ground he could see
almost nothing else. Where was he? Had he stepped out of the back door
of Long John Silvers by mistake?

He decided to make a turn left anyway, and continued walking until he
reached a long stretch of several rows of trees. He kept going in the
same approximate location hoping to get a glance at the compound. The
ground underneath the trees were covered with thorny bushes that he had
seen somewhere and couldn't readily remember.

"I think I have taken a few dumps at spots like this before," he told
himself.

When he got out of the tree area, the sight was open and easy to see for
a good distance, and there was a wide creek in front of him.

This was not Yemen. This was the creek not that far from where he lived
in Dallas! He often took long walks along that creek (and on occasions
had had to take a dump inside the hidden thorny woods area). He turned
right and continued walking along the side of the creek until he reached
a familiar spot from which he knew how to walk home.

40 minutes later he was at the door of his home, looking at the magic
mountain about 400 yards away. He entered. "Ok, let's see what the date
is," he thought to himself.

He checked the pendulum clock on the wall, time was 7:20 pm and yet it
was not dark at all, so at the least 4 months had passed since seeing
the magic mountain first. Back then even 4:30 pm was darker than this.

He sat down and kept thinking, "Ok, now, did I actually eat a couple of
hours back in Long John Silvers or more time than that has passed since?"

He wasn't that hungry at all, so certainly nothing like 48 hours had
passed.

At this point he noticed that the green tabby female cat had begun her
licking of his exposed shoulder. This cat, when she began licking his
skin, she wouldn't stop until her barbed tongue would lick through the
three layers of skin, the flesh underneath it, and all the way down to
the bone that was buried in there! So he knew he had to soon do
something about it. But laziness and the extreme coziness he was feeling
kept him from immediately doing something about it. 10 seconds later he
rolled over and rescued himself from that cat's tongue and the habit she
had with his exposed skin. He was in bed, and now wide awake.

And hungry as hell!

But first was first. He slowly got up (bed was still in the living room)
and went to the window. Yes, the magic mountain was there.

"If I remember everything as it is, it must now be my eating day,
but Hell if I could be sure of that," he thought to himself.

But coffee was sure available to have, so he got his Beaumont Coffee,
Classic Roast, the cheapest fucking coffee East and West of the Pecos,
and brewed, this time, only about a cup full of fresh and strong coffee,
cause he wanted to back that kick with half a caffeine pill as well. He
sometimes did that, and the result was an even more vigorous start of
the day. It worked every time.

White and green tabby cat was still on his lap when he finished his
coffee, so he carefully got her off his lap not to hurt her feelings or
be any disrespectful to her, and stood up.

Before he began to get busy with 200 chores in front of him, a savagely
loud scream came out of the neighbor's house to his east. He often heard
screams like that from that nuthouse cause the occupants of it were four
first class cro-magnon dimwits. White Trash to the core, and all
siblings of each other. Probably fucked each other too, who knew what
they'd do inside their home.

So he didn't pay any attention to it other than cursing that savage
woman yet one more time.

But another scream pierced out of their place and this time it had an
unmistakable pleading pitch to it. Physfit got a bit alarmed and
curious, took his cc and stepped outside to check if things were ok.

The neighbor had a little wooden backdoor porch and their door was open.
None of the usual cars were parked, so everybody must've been out except
that woman. He walked over and as he climbed the back porch he noticed
the woman was sitting at the door frame with one foot 10 inches inside
the deck flooring through a broken lumber.

"This happened again?..." Physfit said. "Yes the fucking place is
falling apart and my brother doesn't do shit about it. I can't get my
foot out and it's hurting like hell", she cried.

Physfit examined the edges of the broken lumber and decided that the
best way is to push the thin lumber farther down to open more space. It
wasn't that difficult, as the wood was weathered and thin and easily
gave in. She slowly pulled her foot out, and thanks to her thick socks
the wound didn't appear something that would require professional care.
In fact she was already much better and the pain had somewhat subdued.

Neighbor: "Each time we change the deck flooring it happens again.
We've tried all sorts of sizes for wood but by next year they get enough
water and ice and sun damage to get brittle again and cannot stand our
weights."

All four living there were Neanderthal size cro-magnons, so Physfit
could understand that.

Physfit: "But this cannot be the right thickness and width for a deck
lumber."

Neighbor: "What do you mean?"

Physfit: "Who fixes your deck flooring for you?"

Neighbor: "That asshole brother of mine. Who else."

Physfit: "Where do you get the material for it?"

Neighbor: "We cut our pecan tree branches just about every year as you
know. We've cut them in all sizes and my brother uses them to shave and
make lumber with them. That's what we've been using so far."

Physfit: "I can't be certain, but I'm kind of sure this lumber is too
thin to be the strongest it can be."

Neighbor: "Well tell that to my dumb brother not me. I have no clue how
to do this stuff."

Physfit" "I think I will. I can tell him how thick and how wide he
should make them to get the strongest form out of them. Show me the
trunks and branches that you got left."

The neighbor with the help of Physfit stood up and with a bit of
exaggerated limp and maximum leaning against his body slowly walked to
where they kept the tree trunks. She always wanted him to fuck her, and
he never did that. Danger of possibly contracting VD aside, she wasn't
as fuckworthy as she once had been either.

Physfit found that most of the cut wood left were more or less of the
same diameter, and they had enough of them to do another deck flooring.

Physfit: "I'll get in touch with your brother when he comes back to
tell him what size he should cut the lumbers for best result."

Neighbor: "Thanks... Do you want a beer or something?..."

You could of course read that as, "Do you want to fuck me right now
before they come back?"

Physfit: "No thanks, I've got to do a few calculations to figure the
right size out :-))"

Neighbor: "Oh, ok. I need to put a warning sign or someth'n on the back
porch in case one of them decides to get in that way."

So the neighbor got help from Physfit to take her there, making sure she
touched as much of her body as was possible, to his, almost managing to
give Physfit ideas.

After that, Physfit said, "Cheers." and left and came home. Grabbed a
piece of paper and a pen, and began thinking about how he could make a
rectangular cross-sectioned lumber out of a log with a certain diameter,
resulting in the maximum strength for the lumber.

An hour later, he had the answer.

If the diameter of the logs were 10 inches, what width and height of the
rectangular cross-section did Physfit recommend to the neighbor's
brother, to get the maximum strength? (not a trivial problem)

Hint for Code Monkey wannabes who do not have engineering or physics
background: the maximum strength of the cut lumber will not correspond
to the maximum area of the rectangular cross-section, which would
obviously be a square, as any of us just by experience may know. The
maximum strength would correspond to the maximum "section modulus" of
the cross-section instead. Dig the rest for yourselves.

Another question I wanted to ask. When standard C library is "updated",
would all the changes and new features be already included in Linux gcc?

If not, what version of standard C library works for gcc? Which one of
C99, C11, C17, C23 (draft released two weeks back)...?

You really have no clue how compilers and libraries work, do you?

Hardly a surprise from the Dunning-Kruger poster boy.

He peeped through the kitchen window to see if the neighbors' cars have
come back. Pendulum clock now was showing almost noon time, and none of
those "true Americans" worked. So whatever booze and drugs buying
escapade they'd embarked on that morning should've ended by then. They
all had! So he took the paper with the sketch of the correct
cross-section on it, and got ready to go there and knock on their doors.

As he came back in the living room area it happened that he surprised
the only male cat he had who wouldn't let him touch him, let alone lift
or hug him. This was a black and white cat who in the hierarchy held
among them, occupied the lowest position. Even the miserable gray cat at
the second to lowest position, who always got bullied by the two other
male cats, would sometimes get a bit of respite in bullying this black
5and white one. And when that happened, the gray cat was ferocious
toward that cat, literally trying to make up for all the humiliation and
stress he was always receiving from the other males.

Physfit had not resolved that situation yet.

And when the black and white got surprised, he ran to hide somewhere,
which triggered the gray one to run after him, and the two other cats
run after both gray and the black and white cats. So suddenly a huge
noisy quarrel began and all four began running and jumping and fighting
and hitting stuff around the living room, throwing them down, etc.

When this happened, which it did about once a week, nothing would work
to stop them but water :) Physfit had to take one of their water bowls
and empty it on as many of them as he could at once. He did that, and
cats quickly dispersed and hid silently somewhere, with the female ones
still where they were, except were now watching this madness intently;
and probably getting yet a bit more feminist as a result. Physfit could
read their faces, "These lunatics..." they may've been thinking.

Physfit took a look around to estimate the damages. Other than all that
extra cleaning up added to usual daily chores, only one item seemed to
have suffered real damage. The pendulum clock. It had fallen down
hitting the hard floor underneath it when one or more cats had jumped
away from it. Its front door was unhinged and thrown off, and the
clock's both hands were missing. It was a piece of shit to begin with.
He'd bought it years back from a thrift store for something like $9. And
for some time he'd messed with it to make it work at all, forget the
accuracy.

The clock was prone to all sorts of disruptions. It was not designed to
automatically correct for any of them. The manufacturer, some fucking
CHINK, had left all that work to the buyers to toil and adjust. Its
functional window as far as being vertical was concerned, did not
include the 100% vertical direction! Right there you could see what type
of _Chink_ had designed it. Someone who'd left the rice fields not that
long before changing jobs.

Physfit had discovered that the pendulum would keep oscillating only
when the clock was held on the wall slightly tilted to one side, and
only to that side, and only to a certain degree, not more. There was not
a way to turn the clockworks part of it itself against the wooden body
of the clock. More than one screw had been used, and they weren't
regular screws either, you'd have to damage them to remove them. Not
wanting to go that far in the repair of the thing, Physfit had decided
to correct for it by tilting the frame itself. It wasn't showing that
much though. But it sure was, again, the hand of a fucking rice field
farmer showing. Or that of an equivalent little Code Monkey wannabe,
begat under some stone somewhere across this land of the brave, thus
turning into a "true American" for us who came and built the USA.

And there were all sorts of other problems with other parts of the
clock. For one, the slider on the pendulum bar for fine tuning
oscillation frequency was way too light for that job. You could move it
all the way up, and clock was still slow, or all the way down and clock
was still fast. Physfit had had to wrap rubber bands around the slider
to make it play a role... imagine what THAT did to the "interior design"
of the living room after the fucking think was tuned and done with,
giving the correct time at last. He'd messed with it so much in so many
different ways that he didn't even want to change the rubber bands with
something more appropriate. He wanted that Chinese _sin_ to exhibit
itself each time you'd notice it; or that stench of a "true American"
type parasite.

It had several other problems. The gears were sharp, showing that clock
was quite new, yet one wind beyond the second, and PRRROPP!, they'd slip
and turn back to the unwound position. There were at least three pivot
points where you could reduce or increase the distances between gears,
both sideways and in a planar way, and yet with nothing that Physfit had
tried, you would find a combination that eradicated the slippage of SOME
gear in there. Result was that this motherfucking thing could only get
safely wound two turns of the key, and never more. The little user
manual said 5 to 7 turns is best. So winding had to get repeated every
week, and not every month as it was supposed to.

The damn thing was also susceptible to temperature variations. The
material used, and the design of it both, were at fault. And this was
Texas! Where temperature often varies 30 to even 40 degrees within the
same 24 hours, repeatedly, in most periods of the year. So this thing
was accurate only in certain hours of each 24 hour period. It was the
mark of China in that house. The mark of rice field workers. A "true
American" thing.

The clock had been knocked down by cats once before, so Physfit
carefully placed the clock back on the wall, adjusted the position as
best as he could (he had marked the wall itself for it), and reinstalled
the detached front door of it whose glass was fortunately not shattered
or cracked.

He then looked for the hands and found them and inserted them back on
the face of the clock. He chose, for now, to position them at 12 o'clock
noon and adjust the fucking time and the clock itself later.

Unbeknownst to him, he had inserted the hands in wrong order,
effectively interchanging the roles of the two hands.

Cats are fucking filthy animals. They potentially harbor Toxoplasma gondii.
For human health, ALL fucking cats should be exterminated.

But all the queer women would hit the streets in protest.

Fuck pendulum clocks.

Surprisingly, the pendulum clock persisted into the 1920's as the only
accurate time piece for science and engineering. By that time, there
were some sophisticated designs for pendulum clocks.

But then quartz oscillators were introduced and they obviated the pendulum
clock.

https://en.wikipedia.org/wiki/Crystal_oscillator

Quartz oscillators are extremely cheap and provide astounding
accuracy. I use them in a lot of my circuits.

Pendulum clocks exist only for antique buffs and old women with
their pussy cats (and toxoplasmosis).

They exterminated them in medieval times in Europe and 2/3rd of human
population there got exterminated instead. By disease carrying mice.

In Egypt, on the other hand, when mice put a definite stop to their main
agricultural grains, they almost gave up, until somebody introduced cats
to households and fields around them. Cats saved the Egyptians, I mean I
have no idea how many tens or hundreds of thousands of them, or even
perhaps more than a million of them were saved. So cats became as
respectable to Egyptians as cows are in India.

There is a full-size statue of a cat among findings of ancient
Egyptians, made of pure gold! They meant that much to them.

Put that another way, if one multiplies an exact Farley a million times,
or 5 million times or more, one gets a nation that will get exterminated
by nature itself :-) Hehe :)

So rejoice, while individuals other than Farleys, also, are around :)

In case you haven't noticed, the Medieval period ended about 700 years
ago and ancient Egypt dropped out about 2500 years ago.

In modern times, there are excellent rodent control measures. There
is no need for cats except for severely repressed females (cat women)
and other highly neurotic human beings.

Now that the cat issue is settled, you are free to comment on the
pendulum time keeping issue.

The medieval period ended when the first dictionary of the English
language itself came out, in the 1700's ! That's just 300 years ago
according to my calculation.
