I would like to get your opinions on this: when exactly does an engaged couple become "married" in God's eyes? Some say that if the two have publically announced their plans to marry, have made their vows to God, and are unswervingly committed to one another (I realize this is a subjective qualifier) they are married/joined in God's sight. Suppose they are unable to get before the altar right at the current time because of purely logistical reasons beyond their control. What do you think about this? Post or e-mail me with general responses. If you need clarification as to what I am asking, please e-mail. Thanks and God bless! ============================================ Robert M.

joe, i'm sorry you felt i was pissing on your list. no disparagement was intended and i would be most interested to know what i said that made you feel that way. i am not suggesting that your list is superflous nor that it will not serve a need. i just would like not to see the boxer contingent split, but there is certainly enough net for more than one list. -- -- bob pasker -- rbp@netcom.com --

I'm looking for a PC that is small and doesn't break apart if you drop it on the groud. It doesn't have to have graphics, text only will do just fine. It doesn't have to be fast either, 8086 will do, I hope. But you must stand a pretty hard enviroment without breaking apart, jumnping on it or trying to use it outdoor while it is raining and so forth. I need 640Kb of memory and a convinient way of loading applications into it that I wrote myself (floppy or somekind of writeable cartridge?). Is there a PC like that?? And where can I get more info? I know of the Atari portfolio but it can't stand the rain.... Marco Seirio - In real life sp1marse@caligula.his.s

My ENT doctor recommended surgery to fix my sinuses. I have a very deviated nasal septum (probably the result at least partially from several fractures). One side has approximately 10-15% of normal flow. Of course I have known this for years but recently discovered that I suffer from chronic sinus infection, discovered during an MRI after a severe migraine. A CT scan subsequently confirmed the problems in the sinuses. He wants to do endoscopic sinus surgery on the ethmoid, maxillary, frontal, and sphenoid, along with nasal septoplasty. He explained the procedure, and the risks. What I would like to know is if there is anyone out there who can tell me "I had this surgery, and it helped me"? (I've already heard from a couple who said they had it and it didn't really help them). I am a moderately severe asthmatic. ENT doc says large percentage see some relief of their asthma after sinus surgery. Also he said it is not unheard of that migraines go away after chronis sinusitis is relieved. I am 42. Any relevant information is appreciated. Regards, Jay Keller Sunnyvale, California badboy@netcom.com

Don Alvarez posted a good partial solution to this problem to comp.risks. I'll present my variant on it instead, since I feel it's a bit stronger against some likely attempts to cheat. depends on the protocol that's followed for reading traffic. Briefly, the cops get a wiretap warrant, and record the call. They then notice the encryption and the disclosure header. It, along with a copy of their warrant, is sent to the FBI, or whoever it is who holds the family key. The F-holder decrypts the header, and sends the serial number N and the encrypted session key U[K] to the escrow agents. They, in turn, use U1 and U2 to recover K, and send that to the local police. Note how this solves the problem of wiretapping forever. Neither the cops nor the FBI ever see U, so they can't read other traffic. Every request must be validated by both the FBI and the escrow agents. The cops and the FBI together can't cheat, since they don't have U. (I regard that as a likely pairing of folks who might try to beat the system. It's to prevent this that I modified Alvarez's scheme.) The escrow agents can't read the conversation, since they don't have it; all they have is N and U[K]. And the police don't even see N. It's harder to see how to block decryption of old, warrantless, wiretaps. There is one protection -- you have to persuade the escrow agents that the call is current. But that's not nearly as strong. There are approaches I can see that might work, involving sequences of data on an unalterable medium, complete with cryptographic protection against insertion onto a new medium. But I don't have anything yet that isn't too complex for comfort, or too hard to install in the real world. The NSA might have an answer; they may or may not be smarter than me, but I've been working on this for a week, and they've had years.

Heres the life of St. MAria Goretti, posted with kind permission of the editor of the Australian Catholic Magazine "Morning Star". Hope you like it. Put up with anything to prevent sin St. Maria Goretti Maria was born on October 16th 1890 to Luigi and Assunta Goretti, the eldest daughter in the family of seven. She was a cheerful girl, always imitating her parents. She had but one disire, but one wish: to receive our Lord in the Blessed Sacrament. The date was finally set for little Maria to receive our Lord on the feast of Corpus Christi. For Maria, time seemed like an eter- nity as she slowly neared the great day. When it finally arrived, Fr. Jerome( the priest who was to celebrate the Mass and give the children their First Holy Communion) delivered a sermon on the immense love of Jesus Christ for them and the great love we should have in return for Him. He then warmly urged them to die rather than commit a mortal sin. Maria humbly approached the Altar of God and received the Holy Eucharist. Her only sadness was the thought of her father's absence, who died some time beforehand. As for the rest of the day, Maria remained under the spell of the divine visit; that is until -4- her thoughts changed to when she could go next to Holy Communion. Thus ended the happiest day of Maria's life. Over the next twelve months, Maria had changed from a giggling little girl into a quiet young lady with responsibilities. As her mother went out into the fields in place of her husband, Maria took on the ironing, cooking, washing and other motherly duties. She was doing this not only for her own family, but also for the Serenellis, a father and son who lived with the Goretti's, owning a share in the farm. Although Maria was poorer than all the other children, she by far surpassed them in virtue. In all thi ngs she did the Holy Will of God. During the month of June, Alessandro Serenelli(the son) twice made advances upon Maria when he chanced to be alone with her. On both occasions Maria managed to struggle free of Alessandro's strong grip, but on the second, he threatened to kill her if she even uttered a word to her mother. From this day on, Maria lived in terror, fearing lest Alessandro attack again. On July 5th 1902, Alessandro left work in the fields to "get a handkerchief," as he claimed. He went to the storeroom beneath the house where Maria, who was outside on the landing with the baby, could hear him fumbling about in with tools. She wondered what he was doing. It was later learned that he was sharpening a 91/2" blade. He went to the house and called for Maria. She told him she wouldn't go to him unless she knew why she was needed. He stormed out to the landing and dragged her up to her room. Mar ia instantly realized what he was up to. "No, No, No! Do not touch me! It is a sin, you will go to Hell!" At this point Alessandro held the knife over Maria's chest, who was now on the floor. "Will you or will you not?" Maria gathered all her energy. "No I will not, Alessandro, no!" She had chosen her martyrdom over sin, God over Satan. Overcome with rage, Alessandro plunged the knife into Maria's breast fourteen times. Finally he came to his senses and thought Maria was dead. Frantically he threw the knife behind a closet and locked himself in his room. The crying of the baby Teresa on the landing brought the attention to Assunta and the father of Alessandro. As the baby was unattended and was in danger of falling off, they ran to the house to find Maria, who, covered in blood, was dragging herself to the door. When asked what happened she said Alessandro stabbed her. "He wanted to make me do wrong and I would not." The ambulance arrived, then the police who took Alessandro away. As the ambulance carried Maria to the hospital, a large crowd followed on foot. The doctors at the hospital held no hope for poor little Maria. The same Fr. Jerome who gave Maria her First Communion -5- came to administer the last rites and to give her Holy Viaticum. He asked Maria if she would forgive her murderer. "Yes. For the love of Jesus I forgive him. I wish for him to one day join me in Paradise. May God forgive him, for I alread y have." Maria died at about three o'clock. Alessandro was tried and found guilty of Maria's death but because of his age he was sentenced to only thirty years in prison. After eight years of being a violent prisoner and show- ing no regret for his crime, he saw in a dream, in the midst of a field of flowers, Maria holding out a bunch of white lilies to him. Soon later he wrote to the local bishop, begging God's par- don for the grave sin he had committed. He later gave testimony in Maria's beatification in 1947. Less than three years later, on Ju ne 24th 1950, Maria was canonised. Assunta Goretti was the first mother ever to be present at her daughter's canonisation. May St. Maria Goretti help us to be pure and grant us the strength to die rather than commit a mortal sin. Saint Maria Goretti, pray for us. by Brendan Arthur -- Internet: simon@giaeb.cc.monash.edu.au Viva Cristo Rey !! Long Live Christ the King.

Well, actually, the Davidians (Koreshians?) started the fire themselves, the last I heard ( around 15:00 EST). Eight people ran out into the feilds surrounding the compound. All were captured and two admitted to setting the fire. I don't buy your napalm theory at all (although it would have made a great commercial for my .sig). Why the hell would they have a wood stove burning on such a warm day? Flame throwers use liquid petroleum, napalm is more of a gel. Now to further dispute your theory, the diluted CS gas was inserted around 06:00 if I understood correctly. The place didn't start burning until around 10:00 or 11:00. > THIS IS MURDER!

There is another useful method based on Least Sqyares Estimation of the sphere equation parameters. The points (x,y,z) on a spherical surface with radius R and center (a,b,c) can be written as (x-a)^2 + (y-b)^2 + (z-c)^2 = R^2 This equation can be rewritten into the following form: 2ax + 2by + 2cz + R^2 - a^2 - b^2 -c^2 = x^2 + y^2 + z^2 Approximate the left hand part by F(x,y,z) = p1.x + p2.x + p3.z + p4.1 For all datapoints, i.c. 4, determine the 4 parameters p1..p4 which minimise the average error |F(x,y,z) - x^2 - y^2 - z^2|^2. In 'Numerical Recipes in C' can be found algorithms to solve these parameters. The best fitting sphere will have - center (a,b,c) = (p1/2, p2/2, p3/2) - radius R = sqrt(p4 + a.a + b.b + c.c). So, at last, will this solve you sphere estination problem, at least for the most situations I think ?. Quick van Rijt, rytg7@fel.tno.nl

The following partial summary of a Theory of the Universe includes a little-known description of the CREATION of our Solar System: LARSONIAN Astronomy and Physics Orthodox physicists, astronomers, and astrophysicists CLAIM to be looking for a "Unified Field Theory" in which all of the forces of the universe can be explained with a single set of laws or equations. But they have been systematically IGNORING or SUPPRESSING an excellent one for 30 years! The late Physicist Dewey B. Larson's comprehensive GENERAL UNIFIED Theory of the physical universe, which he calls the "Reciprocal System", is built on two fundamental postulates about the physical and mathematical natures of space and time: (1) "The physical universe is composed ENTIRELY of ONE component, MOTION, existing in THREE dimensions, in DISCRETE UNITS, and in two RECIPROCAL forms, SPACE and TIME." (2) "The physical universe conforms to the relations of ORDINARY COMMUTATIVE mathematics, its magnitudes are ABSOLUTE, and its geometry is EUCLIDEAN." From these two postulates, Larson developed a COMPLETE Theoretical Universe, using various combinations of translational, vibrational, rotational, and vibrational- rotational MOTIONS, the concepts of IN-ward and OUT-ward SCALAR MOTIONS, and speeds in relation to the Speed of Light (which Larson called "UNIT VELOCITY" and "THE NATURAL DATUM"). At each step in the development, Larson was able to MATCH objects in his Theoretical Universe with objects in the REAL physical universe, (photons, sub-atomic particles [INCOMPLETE ATOMS], charges, atoms, molecules, globular star clusters, galaxies, binary star systems, solar systems, white dwarf stars, pulsars, quasars, ETC.), even objects NOT YET DISCOVERED THEN (such as EXPLODING GALAXIES, and GAMMA-RAY BURSTS). And applying his Theory to his NEW model of the atom, Larson was able to precisely and accurately CALCULATE inter- atomic distances in crystals and molecules, compressibility and thermal expansion of solids, and other properties of matter. All of this is described in good detail, with-OUT fancy complex mathematics, in his books. BOOKS of Dewey B. Larson The following is a complete list of the late Physicist Dewey B. Larson's books about his comprehensive GENERAL UNIFIED Theory of the physical universe. Some of the early books are out of print now, but still available through inter-library loan. "The Structure of the Physical Universe" (1959) "The Case AGAINST the Nuclear Atom" (1963) "Beyond Newton" (1964) "New Light on Space and Time" (1965) "Quasars and Pulsars" (1971) "NOTHING BUT MOTION" (1979) [A $9.50 SUBSTITUTE for the $8.3 BILLION "Super Collider".] [The last four chapters EXPLAIN chemical bonding.] "The Neglected Facts of Science" (1982) "THE UNIVERSE OF MOTION" (1984) [FINAL SOLUTIONS to most ALL astrophysical mysteries.] "BASIC PROPERTIES OF MATTER" (1988) All but the last of these books were published by North Pacific Publishers, P.O. Box 13255, Portland, OR 97213, and should be available via inter-library loan if your local university or public library doesn't have each of them. Several of them, INCLUDING the last one, are available from: The International Society of Unified Science (ISUS), 1680 E. Atkin Ave., Salt Lake City, Utah 84106. This is the organization that was started to promote Larson's Theory. They have other related publications, including the quarterly journal "RECIPROCITY". Physicist Dewey B. Larson's Background Physicist Dewey B. Larson was a retired Engineer (Chemical or Electrical). He was about 91 years old when he died in May 1989. He had a Bachelor of Science Degree in Engineering Science from Oregon State University. He developed his comprehensive GENERAL UNIFIED Theory of the physical universe while trying to develop a way to COMPUTE chemical properties based only on the elements used. Larson's lack of a fancy "PH.D." degree might be one reason that orthodox physicists are ignoring him, but it is NOT A VALID REASON. Sometimes it takes a relative outsider to CLEARLY SEE THE FOREST THROUGH THE TREES. At the same time, it is clear from his books that he also knew ORTHODOX physics and astronomy as well as ANY physicist or astronomer, well enough to point out all their CONTRADICTIONS, AD HOC ASSUMPTIONS, PRINCIPLES OF IMPOTENCE, IN-CONSISTENCIES, ETC.. Larson did NOT have the funds, etc. to experimentally test his Theory. And it was NOT necessary for him to do so. He simply compared the various parts of his Theory with OTHER researchers' experimental and observational data. And in many cases, HIS explanation FIT BETTER. A SELF-CONSISTENT Theory is MUCH MORE than the ORTHODOX physicists and astronomers have! They CLAIM to be looking for a "unified field theory" that works, but have been IGNORING one for over 30 years now! "Modern physics" does NOT explain the physical universe so well. Some parts of some of Larson's books are FULL of quotations of leading orthodox physicists and astronomers who agree. And remember that "epicycles", "crystal spheres", "geocentricity", "flat earth theory", etc., ALSO once SEEMED to explain it well, but were later proved CONCEPTUALLY WRONG. Prof. Frank H. Meyer, Professor Emeritus of UW-Superior, was/is a STRONG PROPONENT of Larson's Theory, and was (or still is) President of Larson's organization, "THE INTERNATIONAL SOCIETY OF UNIFIED SCIENCE", and Editor of their quarterly Journal "RECIPROCITY". He moved to Minneapolis after retiring. "Super Collider" BOONDOGGLE! I am AGAINST contruction of the "Superconducting Super Collider", in Texas or anywhere else. It would be a GROSS WASTE of money, and contribute almost NOTHING of "scientific" value. Most physicists don't realize it, but, according to the comprehensive GENERAL UNIFIED Theory of the late Physicist Dewey B. Larson, as described in his books, the strange GOOFY particles ("mesons", "hyperons", ALLEGED "quarks", etc.) which they are finding in EXISTING colliders (Fermi Lab, Cern, etc.) are really just ATOMS of ANTI-MATTER, which are CREATED by the high-energy colliding beams, and which quickly disintegrate like cosmic rays because they are incompatible with their environment. A larger and more expensive collider will ONLY create a few more elements of anti-matter that the physicists have not seen there before, and the physicists will be EVEN MORE CONFUSED THAN THEY ARE NOW! Are a few more types of anti-matter atoms worth the $8.3 BILLION cost?!! Don't we have much more important uses for this WASTED money?! Another thing to consider is that the primary proposed location in Texas has a serious and growing problem with some kind of "fire ants" eating the insulation off underground cables. How much POISONING of the ground and ground water with insecticides will be required to keep the ants out of the "Supercollider"?! Naming the "Super Collider" after Ronald Reagon, as proposed, is TOTALLY ABSURD! If it is built, it should be named after a leading particle PHYSICIST. LARSONIAN Anti-Matter In Larson's comprehensive GENERAL UNIFIED Theory of the physical universe, anti-matter is NOT a simple case of opposite charges of the same types of particles. It has more to do with the rates of vibrations and rotations of the photons of which they are made, in relation to the vibrational and rotational equivalents of the speed of light, which Larson calls "Unit Velocity" and the "Natural Datum". In Larson's Theory, a positron is actually a particle of MATTER, NOT anti-matter. When a positron and electron meet, the rotational vibrations (charges) and rotations of their respective photons (of which they are made) neutralize each other. In Larson's Theory, the ANTI-MATTER half of the physical universe has THREE dimensions of TIME, and ONLY ONE dimension of space, and exists in a RECIPROCAL RELATIONSHIP to our MATERIAL half. LARSONIAN Relativity The perihelion point in the orbit of the planet Mercury has been observed and precisely measured to ADVANCE at the rate of 574 seconds of arc per century. 531 seconds of this advance are attributed via calculations to gravitational perturbations from the other planets (Venus, Earth, Jupiter, etc.). The remaining 43 seconds of arc are being used to help "prove" Einstein's "General Theory of Relativity". But the late Physicist Dewey B. Larson achieved results CLOSER to the 43 seconds than "General Relativity" can, by INSTEAD using "SPECIAL Relativity". In one or more of his books, he applied the LORENTZ TRANSFORMATION on the HIGH ORBITAL SPEED of Mercury. Larson TOTALLY REJECTED "General Relativity" as another MATHEMATICAL FANTASY. He also REJECTED most of "Special Relativity", including the parts about "mass increases" near the speed of light, and the use of the Lorentz Transform on doppler shifts, (Those quasars with red-shifts greater than 1.000 REALLY ARE MOVING FASTER THAN THE SPEED OF LIGHT, although most of that motion is away from us IN TIME.). In Larson's comprehensive GENERAL UNIFIED Theory of the physical universe, there are THREE dimensions of time instead of only one. But two of those dimensions can NOT be measured from our material half of the physical universe. The one dimension that we CAN measure is the CLOCK time. At low relative speeds, the values of the other two dimensions are NEGLIGIBLE; but at high speeds, they become significant, and the Lorentz Transformation must be used as a FUDGE FACTOR. [Larson often used the term "COORDINATE TIME" when writing about this.] In regard to "mass increases", it has been PROVEN in atomic accelerators that acceleration drops toward zero near the speed of light. But the formula for acceleration is ACCELERATION = FORCE / MASS, (a = F/m). Orthodox physicists are IGNORING the THIRD FACTOR: FORCE. In Larson's Theory, mass STAYS CONSTANT and FORCE drops toward zero. FORCE is actually a MOTION, or COMBINATIONS of MOTIONS, or RELATIONS BETWEEN MOTIONS, including INward and OUTward SCALAR MOTIONS. The expansion of the universe, for example, is an OUTward SCALAR motion inherent in the universe and NOT a result of the so-called "Big Bang" (which is yet another MATHEMATICAL FANTASY). THE UNIVERSE OF MOTION I wish to recommend to EVERYONE the book "THE UNIVERSE OF MOTION", by Dewey B. Larson, 1984, North Pacific Publishers, (P.O. Box 13255, Portland, Oregon 97213), 456 pages, indexed, hardcover. It contains the Astrophysical portions of a GENERAL UNIFIED Theory of the physical universe developed by that author, an UNrecognized GENIUS, more than thirty years ago. It contains FINAL SOLUTIONS to most ALL Astrophysical mysteries, including the FORMATION of galaxies, binary and multiple star systems, and solar systems, the TRUE ORIGIN of the "3-degree" background radiation, cosmic rays, and gamma- ray bursts, and the TRUE NATURE of quasars, pulsars, white dwarfs, exploding galaxies, etc.. It contains what astronomers and astrophysicists are ALL looking for, if they are ready to seriously consider it with OPEN MINDS! The following is an example of his Theory's success: In his first book in 1959, "THE STRUCTURE OF THE PHYSICAL UNIVERSE", Larson predicted the existence of EXPLODING GALAXIES, several years BEFORE astronomers started finding them. They are a NECESSARY CONSEQUENCE of Larson's comprehensive Theory. And when QUASARS were discovered, he had an immediate related explanation for them also. GAMMA-RAY BURSTS Astro-physicists and astronomers are still scratching their heads about the mysterious GAMMA-RAY BURSTS. They were originally thought to originate from "neutron stars" in the disc of our galaxy. But the new Gamma Ray Telescope now in Earth orbit has been detecting them in all directions uniformly, and their source locations in space do NOT correspond to any known objects, (except for a few cases of directional coincidence). Gamma-ray bursts are a NECESSARY CONSEQUENCE of the GENERAL UNIFIED Theory of the physical universe developed by the late Physicist Dewey B. Larson. According to page 386 of his book "THE UNIVERSE OF MOTION", published in 1984, the gamma-ray bursts are coming from SUPERNOVA EXPLOSIONS in the ANTI-MATTER HALF of the physical universe, which Larson calls the "Cosmic Sector". Because of the relationship between the anti-matter and material halves of the physical universe, and the way they are connected together, the gamma-ray bursts can pop into our material half anywhere in space, seemingly at random. (This is WHY the source locations of the bursts do not correspond with known objects, and come from all directions uniformly.) I wonder how close to us in space a source location would have to be for a gamma-ray burst to kill all or most life on Earth! There would be NO WAY to predict one, NOR to stop it! Perhaps some of the MASS EXTINCTIONS of the past, which are now being blamed on impacts of comets and asteroids, were actually caused by nearby GAMMA-RAY BURSTS! LARSONIAN Binary Star Formation About half of all the stars in the galaxy in the vicinity of the sun are binary or double. But orthodox astronomers and astrophysicists still have no satisfactory theory about how they form or why there are so many of them. But binary star systems are actually a LIKELY CONSEQUENCE of the comprehensive GENERAL UNIFIED Theory of the physical universe developed by the late Physicist Dewey B. Larson. I will try to summarize Larsons explanation, which is detailed in Chapter 7 of his book "THE UNIVERSE OF MOTION" and in some of his other books. First of all, according to Larson, stars do NOT generate energy by "fusion". A small fraction comes from slow gravitational collapse. The rest results from the COMPLETE ANNIHILATION of HEAVY elements (heavier than IRON). Each element has a DESTRUCTIVE TEMPERATURE LIMIT. The heavier the element is, the lower is this limit. A star's internal temperature increases as it grows in mass via accretion and absorption of the decay products of cosmic rays, gradually reaching the destructive temperature limit of lighter and lighter elements. When the internal temperature of the star reaches the destructive temperature limit of IRON, there is a Type I SUPERNOVA EXPLOSION! This is because there is SO MUCH iron present; and that is related to the structure of iron atoms and the atom building process, which Larson explains in some of his books [better than I can]. When the star explodes, the lighter material on the outer portion of the star is blown outward in space at less than the speed of light. The heavier material in the center portion of the star was already bouncing around at close to the speed of light, because of the high temperature. The explosion pushes that material OVER the speed of light, and it expands OUTWARD IN TIME, which is equivalent to INWARD IN SPACE, and it often actually DISAPPEARS for a while. Over long periods of time, both masses start to fall back gravitationally. The material that had been blown outward in space now starts to form a RED GIANT star. The material that had been blown OUTWARD IN TIME starts to form a WHITE DWARF star. BOTH stars then start moving back toward the "MAIN SEQUENCE" from opposite directions on the H-R Diagram. The chances of the two masses falling back into the exact same location in space, making a single lone star again, are near zero. They will instead form a BINARY system, orbiting each other. According to Larson, a white dwarf star has an INVERSE DENSITY GRADIENT (is densest at its SURFACE), because the material at its center is most widely dispersed (blown outward) in time. This ELIMINATES the need to resort to MATHEMATICAL FANTASIES about "degenerate matter", "neutron stars", "black holes", etc.. LARSONIAN Solar System Formation If the mass of the heavy material at the center of the exploding star is relatively SMALL, then, instead of a single white dwarf star, there will be SEVERAL "mini" white dwarf stars (revolving around the red giant star, but probably still too far away in three-dimensional TIME to be affected by its heat, etc.). These will become PLANETS! In Chapter 7 of THE UNIVERSE OF MOTION, Larson used all this information, and other principles of his comprehensive GENERAL UNIFIED Theory of the physical universe, to derive his own version of Bode's Law. "Black Hole" FANTASY! I heard that physicist Stephen W. Hawking recently completed a theoretical mathematical analysis of TWO "black holes" merging together into a SINGLE "black hole", and concluded that the new "black hole" would have MORE MASS than the sum of the two original "black holes". Such a result should be recognized by EVERYone as a RED FLAG, causing widespread DOUBT about the whole IDEA of "black holes", etc.! After reading Physicist Dewey B. Larson's books about his comprehensive GENERAL UNIFIED Theory of the physical universe, especially his book "THE UNIVERSE OF MOTION", it is clear to me that "black holes" are NOTHING more than MATHEMATICAL FANTASIES! The strange object at Cygnus X-1 is just an unusually massive WHITE DWARF STAR, NOT the "black hole" that orthodox astronomers and physicists so badly want to "prove" their theory. By the way, I do NOT understand why so much publicity is being given to physicist Stephen Hawking. The physicists and astronomers seem to be acting as if Hawking's severe physical problem somehow makes him "wiser". It does NOT! I wish the same attention had been given to Physicist Dewey B. Larson while he was still alive. Widespread publicity and attention should NOW be given to Larson's Theory, books, and organization (The International Society of Unified Science). ELECTRO-MAGNETIC PROPULSION I heard of that concept many years ago, in connection with UFO's and unorthodox inventors, but I never was able to find out how or why they work, or how they are constructed. I found a possible clue about why they might work on pages 112-113 of the book "BASIC PROPERTIES OF MATTER", by the late Physicist Dewey B. Larson, which describes part of Larson's comprehensive GENERAL UNIFIED Theory of the physical universe. I quote one paragraph: "As indicated in the preceding chapter, the development of the theory of the universe of motion arrives at a totally different concept of the nature of electrical resistance. The electrons, we find, are derived from the environment. It was brought out in Volume I [Larson's book "NOTHING BUT MOTION"] that there are physical processes in operation which produce electrons in substantial quantities, and that, although the motions that constitute these electrons are, in many cases, absorbed by atomic structures, the opportunities for utilizing this type of motion in such structures are limited. It follows that there is always a large excess of free electrons in the material sector [material half] of the universe, most of which are uncharged. In this uncharged state the electrons cannot move with respect to extension space, because they are inherently rotating units of space, and the relation of space to space is not motion. In open space, therefore, each uncharged electron remains permanently in the same location with respect to the natural reference system, in the manner of a photon. In the context of the stationary spatial reference system the uncharged electron, like the photon, is carried outward at the speed of light by the progression of the natural reference system. All material aggregates are thus exposed to a flux of electrons similar to the continual bombardment by photons of radiation. Meanwhile there are other processes, to be discussed later, whereby electrons are returned to the environment. The electron population of a material aggregate such as the earth therefore stabilizes at an equilibrium level." Note that in Larson's Theory, UNcharged electrons are also massLESS, and are basically photons of light of a particular frequency (above the "unit" frequency) spinning around one axis at a particular rate (below the "unit" rate). ("Unit velocity" is the speed of light, and there are vibrational and rotational equivalents to the speed of light, according to Larson's Theory.) [I might have the "above" and "below" labels mixed up.] Larson is saying that outer space is filled with mass- LESS UN-charged electrons flying around at the speed of light! If this is true, then the ELECTRO-MAGNETIC PROPULSION fields of spacecraft might be able to interact with these electrons, or other particles in space, perhaps GIVING them a charge (and mass) and shooting them toward the rear to achieve propulsion. (In Larson's Theory, an electrical charge is a one-dimensional rotational vibration of a particular frequency (above the "unit" frequency) superimposed on the rotation of the particle.) The paragraph quoted above might also give a clue to confused meteorologists about how and why lightning is generated in clouds. SUPPRESSION of LARSONIAN Physics The comprehensive GENERAL UNIFIED Theory of the physical universe developed by the late Physicist Dewey B. Larson has been available for more than 30 YEARS, published in 1959 in his first book "THE STRUCTURE OF THE PHYSICAL UNIVERSE". It is TOTALLY UN-SCIENTIFIC for Hawking, Wheeler, Sagan, and the other SACRED PRIESTS of the RELIGION they call "science" (or "physics", or "astronomy", etc.), as well as the "scientific" literature and the "education" systems, to TOTALLY IGNORE Larson's Theory has they have. Larson's Theory has excellent explanations for many things now puzzling orthodox physicists and astronomers, such as gamma-ray bursts and the nature of quasars. Larson's Theory deserves to be HONESTLY and OPENLY discussed in the physics, chemistry, and astronomy journals, in the U.S. and elsewhere. And at least the basic principles of Larson's Theory should be included in all related courses at UW-EC, UW-Madison, Cambridge, Cornell University, and elsewhere, so that students are not kept in the dark about a worthy alternative to the DOGMA they are being fed. For more information, answers to your questions, etc., please consult my CITED SOURCES (especially Larson's BOOKS).

Anyone out there know? Every aircraft has flight constraints for speed/AOA/power. When graphed, these define the 'flight envelope' of that aircraft, presumably so named because the graphed line encloses (envelopes) the area on the graph that represents conditions where the aircraft doesn't fall out of the sky. Hence, 'pushing the envelope' becomes 'operating at (or beyond) the edge of the flight (or operational) envelope'. Note that the envelope isn't precisely known until someone actually flies the airplane in those regions -- up to that point, all there are are the theoretical predictions. Hence, one of the things test pilots do for a living is 'push the envelope' to find out how close the correspondence between the paper airplane and the metal one is -- in essence, 'pushing back' the edges of the theoretical envelope to where the airplane actually starts to fail to fly. Note, too, that this is done is a quite calculated and careful way; flight tests are generally carefully coreographed and just what is going to be 'pushed' and how far is precisely planned (despite occasional deviations from plans, such as the 'early' first flight of the F-16 during its high-speed taxi tests).

From: Center for Policy Research <cpr> Subject: Zionists reject non-Jews. News Ethiopian Jews and not-quite Jews The Israeli press has published items about Ethiopian Jews waiting in camps in Addis Ababa for immigration to Israel, who are dying of starvation. The following are excerpts from an interview with the former general director of the JDC project for development and welfare of Ethiopian Jews, Kobi Friedman (Hadashot, 21 April 1993), who has stated that "there are people dying in Addis Ababa, but they are converts to Christianity": "Hadashor published the item about the dying Jews after viewing a video tape filmed last week in Adis Ababa. How do you know that they are actually converts to Chritianity ? "If there are Jews on the tape, then I don't know what to say. I am speaking from experience when I say that those who remained in Ethiopia are Christians. I know that there have previously been things published in the press by interesting parties, and there is no connection between them and reality." "What interested parties ?" "Ethiopian immigrants who want their Christian relatives to come here." "What to you recommend that Ethiopian children in Israel do, when their parents and the rest of their relatives remain in Ethiopia ?" "I ask if it is the job of the State of Israel to bring in the 40 relatives who stayed in Ethiopia. Well, my answer is that it is not. It would be a better solution, economically as well, for that young man to buy a one-way ticket to Ethiopia and reunite with his family there." ***************************************** Publ. by The OTHER Front, Alternative Information Center Jerusalem, Israel 28 April 1993

To receive information describing how you can use the mail handler, simply mail graphtext@cs.brown.edu and put the word "Help" in the Subject line. Use the Subject line "Software-Distribution" to receive information specifically concerning the software packages SRGP and SPHIGS. Errata for "An Introduction to Ray Tracing" is available on wuarchive.wustl.edu in graphics/graphics/books/IntroToRT.errata. Errata for "Digital Image Warping" is in the same directory as "Digital-Image-Warping.errata". All C code from the "Graphics Gems" series is available via anonymous ftp from princeton.edu. Look in the directory pub/Graphics/GraphicsGems for the various volumes (Gems, GemsII, GemsIII), and get the README file first. Errata to _Graphics Gems_ and _Graphics Gems II is available on wuarchive.wustl.edu in graphics/graphics/books. A list of computer graphics, computational geometry and image processing journals is available from Juhana Kouhia, jk87377@cs.tut.fi. 2) Drawing three-dimensional objects on a two-dimensional screen. The simple answer is, you divide by the depth. For a more verbose explanation, see any of the above references, starting with: The Foley & Van Dam & Feiner & Hughes "Computer Graphics" book is certainly a good start. Chapter 6 is "Viewing in 3D", then read chapter 15, "Visible-Surface Determination". For more information go to chapter 16 for shading, chapter 19 for clipping, and branch out from there. 3) Quantizing 24 bit images down to 8 bits. Find a copy of "Color Image Quantization for Frame Buffer Display" by Paul Heckbert, SIGGRAPH '82 Proceedings, page 297. There are other algorithms, but this one works well and is fairly simple. Implementations are included in most raster toolkits (see item 7 below). A variant method is described in "Graphics Gems", p. 287-293. Note that the code from the "Graphics Gems" series is all available from an FTP site, as described above. Check out John Bradley's "Diversity Algorithm", which is incorporated into the xv package and described in the back of the manual. The ImageMagick package (see section 7 for where it is) contains another quantizing algorithm which is presented as "doing a better job than the other algorithms, but slower". There's also an implementation of: Wan, Wong, and Prusinkiewicz, _An Algorithm for Multidimensional Data Clustering_, Transactions on Mathematical Software, Vol. 14 #2 (June, 1988), pp. 153-162. avialable as princeton.edu:pub/Graphics/colorquant.shar. This code, in modified form, appears in the Utah Raster Toolkit as well. 4) Converting color into grayscale. The NTSC formula is: luminosity = .299 red + .587 green + .114 blue 5) Quantizing grayscale to black&white. The only reference you need for this stuff is: Digital Halftoning, Robert Ulichney, MIT Press 1987, ISBN 0-262-21009-6 But before you go off and start coding, check out the image manipulation software mentioned in item 7 below. All of the packages mentioned can do some form of gray to b&w conversion. 6) Rotating a raster image by an arbitrary angle. The obvious but wrong method is to loop over the pixels in the source image, transform each coordinate, and copy the pixel to the destination. This is wrong because it leaves holes in the destination. Instead, loop over the pixels in the destination image, apply the *reverse* transformation to the coordinates, and copy that pixel from the source. This method is quite general, and can be used for any one-to-one 2-D mapping, not just rotation. You can add anti-aliasing by doing sub-pixel sampling. However, there is a much faster method, with antialising included, which involves doing three shear operations. The method was originally created for the IM Raster Toolkit (see below); an implementation is also present in PBMPLUS. Reference: "A Fast Algorithm for Raster Rotation", by Alan Paeth (awpaeth@watcgl.waterloo.edu) Graphics Interface '86 (Vancouver). An article on the IM toolkit appears in the same journal. An updated version of the rotation paper appears in "Graphics Gems" (see section [1]) under the original title. 7) Free image manipulation software. There are a number of toolkits for converting from one image format to another, doing simple image manipulations such as size scaling, plus the above-mentioned 24 -> 8, color -> gray, gray -> b&w conversions. Here are pointers to some of them: xv by John Bradley. X-based image display, manipulation, and format conversion package. XV displays many image formats and permits editing of GIF files, among others. The program was updated 5/92; see the file contrib/xv-2.21.tar.Z on export.lcs.mit.edu. PBMPLUS, by Jef Poskanzer. Comprehensive format conversion and image manipulation package. The latest version is always available via anonymous FTP as ftp.ee.lbl.gov:pbmplus*.tar.Z, wuarchive.wustl.edu:graphics/graphics/packages/pbmplus/pbmplus*.tar.Z, and export.lcs.mit.edu:contrib/pbmplus*.tar.Z. IM Raster Toolkit, by Alan Paeth (awpaeth@watcgl.uwaterloo.ca). Provides a portable and efficient format and related toolkit.

Binaries for some machines available via anonymous FTP in sdsc.edu:sdscpub. The Independent JPEG Group has written a package for reading and writing JPEG files. FTP to ftp.uu.net:graphics/jpeg/jpegsrc.v?.tar.Z Don't forget to set binary mode when you FTP tar files. For you MILNET folks who still don't have name servers, the IP addresses are: ads.com 128.229.30.16 cs.utah.edu 128.110.4.21 coral.cs.jcu.edu.au 137.219.17.4 export.lcs.mit.edu 18.24.0.12 freebie.engin.umich.edu 141.212.103.21 ftp.ee.lbl.gov 128.3.112.20 ftp.uu.net 137.39.1.9 or 192.48.96.9 gis.mit.edu 18.80.1.118 gondwana.ecr.mu.oz.au 128.250.70.62 karazm.math.uh.edu 129.7.7.6 marsh.cs.curtin.edu.au 134.7.1.1 nic.funet.fir 128.214.6.100 ftp.ncsa.uiuc.edu 141.142.20.50 nl.cs.cmu.edu 128.2.222.56 pit-manager.mit.edu 18.172.1.27 pprg.eece.unm.edu 129.24.24.10 princeton.edu 128.112.128.1 sdsc.edu 132.249.20.22 ucbvax.berkeley.edu 128.32.133.1 venera.isi.edu 128.9.0.32 weedeater.math.yale.edu 128.36.23.17 wuarchive.wustl.edu 128.252.135.4 zamenhof.cs.rice.edu 128.42.1.75 Please do *not* post or mail messages saying "I can't FTP, could someone mail this to me?" There are a number of automated mail servers that will send you things like this in response to a message. See item 13 below for details on some. Also, the newsgroup alt.graphics.pixutils is specifically for discussion of software like this. You may find useful information there. 8) Format documents for TIFF, IFF, BIFF, NFF, OFF, FITS, etc. You almost certainly don't need these. Read the above item 7 on free image manipulation software. Get one or more of these packages and look through them. Chances are excellent that the image converter you were going to write is already there. But if you still want one of the format documents, many such files are available by anonymous ftp from zamenhof.cs.rice.edu in directory pub/graphics.formats. These files were collected off the net and are believed to be correct. This archive includes pixel formats, and two- and three-dimensional object formats. The future of this archive is uncertain at the moment, as Mark Hall <foo@cs.rice.edu> will apparently no longer be maintaining it. A second graphics file format archive is now being actively maintained by Quincey Koziol (koziol@ncsa.uiuc.edu). The latest version exists at ftp.ncsa.uiuc.edu in /misc/file.formats/graphics.formats. Apparently, neither of these is complete, you might want to check both. FITS stands for Flexible Image Transport System. It's a file format most often used in astronomy. Despite the name, it can contain not only images but other things as well. There is a regular monthly FITS basics and information posting on sci.astro.fits - read it if you want to know more. 9) Converting between vector formats. A lot of people ask about converting from HPGL to PostScript, or MacDraw to CGM, or whatever. It is important to understand that this is a very different problem from the image format conversions in item 7. Converting one image format to another is a fairly easy problem, since once you get past all the file header junk, a pixel is a pixel -- the basic objects are the same for all image formats. This is not so for vector formats. The basic objects -- circles, ellipses, drop-shadowed pattern-filled round-cornered rectangles, etc. -- vary from one format to another. Except in extremely restricted cases, it is simply not possible to do a one-to-one conversion between vector formats. There is software for converting to and from CGM files on ftp.psc.edu. The contributor states that it runs on Unix, MS-Windows, and possibly the Mac. A better, more specific blurb would be most welcome. On the other hand, it is quite possible to do a close approximation, rendering an image from one format using the primitives from another. As far as I know, no one has put together a general toolkit of such converters, but two different HPGL to PostScript converters have been posted to comp.sources.misc. Check the index on your nearest archive site. A related frequent question is how to convert from some vector format to a bitmapped image - from PostScript to Sun raster format, or HPGL to X11 bitmap. For example, some of the commercial PostScript clones for PC's allow you to render to a disk file as well as a printer. Also, the PostScript interpreters in the NeXT box and in Sun's X11/NeWs can be used to render to a file if you're clever. But in general, the answer is no. However, if someone were to put together a vector to vector conversion toolkit, adding a vector to raster converter would be trivial. GNU ghostscript (from the FSF - current version 2.5.2) includes drivers for both ppm and gif format files, thus it can be used as a PostScript to ppm or a PostScript to GIF filter. (It implements essentially all of PostScript level 1 and alot of Display PostScript and level 2). 10) How to get Pixar films.

For institutional orders, add $5 S&H for the first tape, $3 for each additional tape. Foreign shipping, add $3/tape or shirt. Call 800-525-0000 (213-396-4774 international, 213-396-3233 FAX) to charge to your credit card. Call first to verify prices and availability. Or, just write to: Direct Cinema Limited 1749 14th Street Santa Monica, CA 90404-4342 Allan Braunsdorf has this to say: At SIGGRAPH they were selling a tape with all four shorts for $25. That was a sale price. You can get it for slightly more than that normally. ($35 maybe.) I believe it's available from RenderMan Retail (at Pixar's address). Pixar 1001 West Cutting Blvd. Richmond, CA. 94804 (510) 236-4000 (510) 236-0388 (FAX) You can obtain a video directly from Pixar which contains "Luxo, Jr.", "Red's Dream", "Tin Toy" and "Knicknack" for $25.00, plus $2.50 for shipping. They will take your order over the phone or via FAX with a major credit card. I ordered mine just last week and received it several days later. Don't expect to be able to rent a copy from your local video store. According to the license agreement printed on the back cover of the case, it cannot be rented. 11) How do I draw a circle as a Bezier (or B-spline) curve? The short answer is, "You can't." Unless you use a rational spline you can only approximate a circle. The approximation may look acceptable, but it is sensitive to scale. Magnify the scale and the error of approximation magnifies. Deviations from circularity that were not visible in the small can become glaring in the large. If you want to do the job right, consult the article: "A Menagerie of Rational B-Spline Circles" by Leslie Piegl and Wayne Tiller in IEEE Computer Graphics and Applications, volume 9, number 9, September, 1989, pages 48-56. For rough, non-rational approximations, consult the book: Computational Geometry for Design and Manufacture by I. D. Faux and M. J. Pratt, Ellis Horwood Publishers, Halsted Press, John Wiley 1980. For the best known non-rational approximations, consult the article: "Good Approximation of Circles by Curvature-continuous Bezier Curves" by Tor Dokken, Morten Daehlen, Tom Lyche, and Knut Morken in Computer Aided Geometric Design, volume 7, numbers 1-4 (combined), June, 1990, pages 33-41 [Elsevier Science Publishers (North-Holland)] 12) How to order standards documents. The American National Standards Institute sells ANSI standards, and also ISO (international) standards. Their sales office is at 1-212-642-4900, mailing address is 1430 Broadway, NY NY 10018. It helps if you have the complete name and number. Some useful numbers to know: CGM (Computer Graphics Metafile) is ISO 8632-4 (1987). GKS (Graphical Kernel System) is ANSI X3.124-1985. PHIGS (Programmer's Hierarchical Interactive Graphics System) is ANSI X3.144-1988. IGES is ASME/ANSI Y14.26M-1987. Language bindings are often separate but related numbers; for example, the GKS FORTRAN binding is X3.124.1-1985. Standards-in-progress are made available at key milestones to solicit comments from the graphical public (this includes you!). ANSI can let you know where to order them; most are available from Global Engineering at 1-800-854-7179. 13) How to FTP by email. There are a number of sites that archive the Usenet sources newsgroups and make them available via an email query system. You send a message to an automated server saying something like "send comp.sources.unix/fbm", and a few hours or days later you get the file in the mail. In addition, there is at least one FTP-by-mail server. Send mail to ftpmail@decwrl.dec.com saying "help" and it will tell you how to use it. Note that this service has at times been turned off due to abuse. 14) How to tell whether a point is within a planar polygon. Consider a ray originating at the point of interest and continuing to infinity. If it crosses an odd number of polygon edges along the way, the point is within the polygon. If the ray crosses an even number of edges, the point is either outside the polygon, or within an interior hole formed from intersecting polygon edges. This idea is known in the trade as the Jordan curve theorem; see Eric Haines' article in Glassner's ray tracing book (above) for more information, including treatment of special cases. Another method is to sum the absolute angles from the point to all the vertices on the polygon. If the sum is 2 pi, the point is inside, if the sum is 0 the point is outside. However, this method is about an order of magnitude slower than the previous method because evaluating the trigonometric functions is usually quite costly. Code for both methods (plus barycentric triangle testing) can be found in the Ray Tracing News, Vol. 5, No. 3, available from princeton.edu: pub/Graphics/RTNews/RTNv5n3.Z. 15) How to tessellate a sphere. One simple way is to do recursive subdivision into triangles. The base of the recursion is an octahedron, and then each level divides each triangle into four smaller ones. Jon Leech <leech@cs.unc.edu> has posted a nice routine called sphere.c that generates the coordinates. It's available for FTP on ftp.ee.lbl.gov and princeton.edu. 16) Specific references on ray-tracing and global illumination. Rick Speer maintains a cross-indexed ray-tracing bibliography: Highlights of this edition- i) more than 500 citations spanning the period from 1968 through November '91; ii) papers from all Siggraph, Graphics Interface, Eurographics, CG International and Ausgraph proceedings through December, '91; iii) all citations keyworded for easy lookup; iv) cross-indices by keyword and author; v) glossary of the 119 keywords used. The bib is in the form of a PostScript file. The printout is 41 pages long. Below is a list of ftp sites and the dirs that contain the file. It's named "speer.raytrace.bib.ps.Z" and is compressed at most sites- Site Dir wuarchive.wustl.edu graphics/graphics/bib/RT.BIB.Speer/ karazm.math.uh.edu pub/Graphics/ gondwana.ecr.mu.oz.au pub/papers/ nic.funet.fi pub/sci/papers/graphics coral.cs.jcu.edu.au graphics/papers/ Eric Haines (erich@eye.com) maintains ray tracing and radiosity/global illumination bibliographies. These are in "refer" format, and so can be searched electronically (a simple awk script to search for keywords is included with each). The bibliographies are available at most of the sites listed above, and the most current versions are maintained at princeton.edu: pub/Graphics/Papers as "RayBib.*" and "RadBib.*". Tom Wilson (wilson@cs.ucf.edu) has collected over 300 abstracts from ray tracing related research papers and books. The information is essentially in plaintext, and Latex and troff formatting programs are included. This collection is available at most of the sites above as "rtabs.*". 17) SIGGRAPH information online [from Steve Cunningham and Ralph Orlick] ACM-SIGGRAPH announces its online information site at siggraph.org (128.248.245.250). This site now provides SIGGRAPH information via both anonymous ftp and an electronic mail archive server. The anonymous ftp service is very standard, and the ftp directory includes both conference and publications subdirectories. To retrieve information by electronic mail, send mail to archive-server@siggraph.org and in the subject or the body of the message include the message send followed by the topic and subtopic you wish. A good place to start is with the command send index which will give you an up-to-date list of available information. 18) SIGGRAPH Panels Proceedings available [from Steve Cunningham and Bob Judd] ACM SIGGRAPH announces the availability of the SIGGRAPH '91 Panels Proceedings at the siggraph.org site (128.248.245.250). The proceedings are available in three formats: text (ASCII) rtf (rich text format, suitable for many word processors) word (MS Word for the Macintosh) They may be retrieved from siggraph.org in two ways: (1) by anonymous ftp change to one of the directories publications/s91/panels_proceedings/[text|rtf|word] The text and rtf files may be downloaded in ASCII mode, while the word files are stored in MacBinary format and must be downloaded in binary mode. Each directory contains a Table of Contents file (TOC) that describes the contents of each panel file. (2) by electronic mail send mail to archive-server@siggraph.org You can retrieve either the text or rtf files. We suggest that you first retrieve the index files by putting one of the messages send panel91-txt index send panel91-rtf index in the subject or body of the message. You will get the necessary information to retrieve the actual transcript files. 19) Graphics mailing lists There are a variety of graphics-related mailing list out there, each covering either a single product or a single topic. I have been an active participant in one of these for some time now, and find the focus and expertise which can be brought to bear on an isolated topic to be nothing short of amazing. Please send me the appropriate information if you have any others you would like to see added.

Comments - 26 formats, no software (this is good, IMHO - I prefer books which are non-platform-dependent). Questions about this book may be sent to gbook@iecc.cambridge.ma.us. 21) What about GIF? GIF stands for Graphics Interchange Format. It is portable and usable upon a wide variety of platforms. It is quite limited in some ways (yes, the keeper of the FAQ has some opinions after all), and in fact, I don't like it much. However, it looks to me like the most-Frequently Asked Question which was not previously covered in this list. The following is a list of newsgroups and the like where one could go to find out about GIF. Subject: alt.binaries.pictures FAQ - General info Subject: alt.binaries.pictures FAQ - OS specific info Newsgroups: alt.binaries.pictures.d,alt.binaries.pictures.misc, alt.binaries.pictures.utilities,alt.binaries.pictures.fractals, alt.binaries.pictures.fine-art.d,news.answers Available in the indicated USENET newsgroup(s), or via anonymous ftp from pit-manager.mit.edu in the files: /pub/usenet/news.answers/pictures-faq/part1 /pub/usenet/news.answers/pictures-faq/part2 Also available from mail-server@pit-manager.mit.edu by sending a mail message containing any or all of: send usenet/news.answers/pictures-faq/part1 send usenet/news.answers/pictures-faq/part2 Send a message containing "help" to get general information about the mail server. Also, you could check out the resources described in sections 7, 8, and 20 above for more information. 22) What is morphing? Warping is the deformation of an image by mapping each pixel to a new location. Morphing is blending from one image or object to another one. Valerie Hall has written an excellent introduction to warping and morphing. This is available for anonymous ftp from marsh.cs.curtin.edu.au in the directory pub/graphics/bibliography/Morph. There are three files: morph_intro.ps.Z (PostScript version, many pictures - 1.5M) morph_intro.txt.Z (text version) m_responses.Z (Responses to morphing questions) The files are compressed, so you must use binary transfer and uncompress them afterwards. 23) How to ray-trace height fields Height fields are a special case in ray-tracing. They have a number of uses, such as terrain rendering, and some optimization is possible. Thus, they get their own FAQ section. Note that further references can no doubt be located via the ray-tracing bibs in section 16 above. The following paper seems to be the definitive reference: F.

Pn, not in the x-y plane, is given by Area(Polygon) = 1/2 * | N . Sigma { Pk x Pk+1 } | where N is the unit vector normal to the plane and P is a polygonal vertex. The . represents the dot product operator and the x represents the cross product operator. Sigma represents the summation operator. | | represents the absolute value operator. Pn+1 is equal to P0. 25) How to join ACM/SIGGRAPH Probably the easiest way to join ACM/SIGGRAPH is to trot over to your local technical library and find a copy of Communications of the ACM. Somewhere within the first few pages will be an application blank. Fill it out and mail it in. ACM membership for students costs $23.00, Voting or Associate Membership $77.00 (yearly) SIGGRAPH student membership costs an additional $16.00, $26.00 for Voting or Associate Members (also yearly). To get TOG (Transactions on Graphics) it's another $26.00 for students and $31.00 for Voting or Associate Members. If you just want to join SIGGRAPH without joining ACM, it'll cost you $59.00 (no student discount). There are surcharges for overseas airmailing of publications. ACM Member services may be contacted via email at acmhelp@acmvm.bitnet. Their phone number is (212) 626-0500. FAX number (212) 944-1318.

The condition of the Ctrl key BEFORE you press the mouse button makes no difference whatsoever.

Subject: Introduction/Disclaimers Although we've done a fair bit of wiring, we are not electricians, and we cannot be responsible for what you do. If you're at all uncertain about what is correct or safe, *don't do it*. Contact someone qualified -- a licensed electrician, or your local electrical inspector. Electricity is no joke; mistakes can result in shocks, fires, or electrocution. Furthermore, our discussion is based on the U.S. National Electrical Code (NEC) and the Canadian Electrical code (CEC). To the best of our abilities, we have confirmed every detail with the electrical code, but we don't quote sections simply to keep this thing readable. If you think we're wrong, we invite you to correct us, but please - quote references! The NEC and the CEC do not, in and of themselves, have the force of law. Many municipalities adopt it en toto. Others, however, do not. Check your with your local building department (and <provincial> Hydro Inspection Offices in Canada) to find out what applies in your area. Also, your local electrical utility may also have special requirements for electrical service installation. Bear in mind, too, that we say here applies primarily to ordinary single-family residences. Multi-family dwellings, mobile homes, commercial establishments, etc., are sometimes governed by different rules. Also note that, contrary to popular belief in the U.S. (and in some parts of Canada), Canada is not a wholly-owned subsidiary of the U.S. Consequently, the NEC does not apply in Canada. Lots of things are the same, including voltages, line frequencies, and the laws of physics. But there are a number of crucial differences in the regulations. Where we can, we've noted them, flagging the relevant passages with ``NEC'' or ``CEC''. Remember that the CEC and NEC are minimal standards. It is often smart to go beyond their minimal requirements. Subject: What is the NEC? Where can I get a copy? The NEC is a model electrical code devised and published by the National Fire Protection Association, an insurance industry group. It's revised every three years. The 1993 version has been released. You can buy a copy at a decent bookstore, or by calling them directly at 800-344-3555. The code exists in several versions. There's the full text, which is fairly incomprehensible. There's an abridged edition, which has only the sections likely to apply to most houses. And there's the NEC Handbook, which contains the ``authorized commentary'' on the code, as well as the full text. That's the recommended version. Unfortunately, there's no handbook for the abridged edition. And the full handbook is expensive -- US$65 plus shipping and handling. Subject: What is the CEC? Where can I get a copy? The Canadian Standards Association is an organization made up of various government agencies, power utilities, insurance companies, electrical manufacturers and other organizations. The CSA publishes CSA Standard C22.1 which is updated every two or three years. Each province adopts, with some amendments, this standard and publishes a province-specific code book. Since each province publishes its own slightly modified standard, it would be somewhat confusing to obtain the CSA standard itself. In this FAQ, "CEC" really means the appropriate provincial standard. In particular, this FAQ is derived from the Ontario Hydro Electrical Safety Code, 20th edition (1990). Which is in turn based on CSA C22.1-1990 (16th edition). While differences exist between the provinces, an attempt has been made to avoid specific-to-Ontario detail. The appropriate provincial code can be obtained from electrical inspection offices of your provincial power authority. In Ontario, it's Ontario Hydro. The Ontario Hydro book isn't overly fat. It's about C$25, and includes mailed updates. I hear that these standards are somewhat easier to read than the equivalent NEC publications. Don't bother asking in Quebec - DIY wiring is banned throughout the province. Subject: Can I do my own wiring? Extra pointers? In most places, homeowners are allowed to do their own wiring. In some, they're not. Check with your local electrical inspector. Most places won't permit you to do wiring on other's homes for money without a license. Nor are you permitted to do wiring in "commercial" buildings. Multiple dwellings (eg: duplexes) are usually considered "semi-commercial" or "commercial". However, many jurisdictions will permit you to work on semi-commercial wiring if you're supervised by a licensed electrician - if you can find one willing to supervise. If you do your own wiring, an important point: Do it NEAT and WELL! What you really want to aim for is a better job than an electrician will do. After all, it's your own home, and it's you or your family that might get killed if you make a mistake. An electrician has time pressures, has the skills and knows the tricks of the trade to do a fast, safe job. In this FAQ we've consciously given a few recommendations that are in excess of code, because we feel that it's reasonable, and will impress the inspector. The inspector will know that you're an amateur. You have to earn his trust. The best way of doing this is to spend your time doing as neat a job as possible. Don't cut corners. Exceed specifications. Otherwise, the inspector may get extremely picky and fault you on the slightest transgressions. Don't try to hide anything from the inspector. Use the proper tools. Ie: don't use a bread knife to strip wires, or twist wires with your fingers. The inspector won't like it, and the results won't be that safe. And it takes longer. And you're more likely to stick a hunk of 12ga wire through your hand that way. Don't handle house wire when it's very cold (eg: below -10C or 16F). Thermoplastic house wire, particularly older types become very brittle. Subject: What do I need in the way of tools? First, there's the obvious -- a hammer, a drill, a few screwdrivers, both straight and Phillips-head. If you're lucky enough to live in Canada (or find a source of CSA-approved devices) you need Robertson ("square recess") screwdrivers (#1 and #2) instead of phillips. For drilling a few holes, a 3/4" or 1" spade bit and 1/4" or 3/8" electric drill will do. If you're doing a lot, or are working with elderly lumber, we recommend a 1/2" drill (right-angle drills are wonderful. Can be rented) and 3/4" or 1" screw-point auger drill bits. These bits pull you through, so they're much faster and less fatiguing, even in 90 year old hardwood timbers. Screw-driver bits are useful for drills, expecially if you install your electrical boxes using screws (drywall screws work well). For stripping wire, use a real wire stripper, not a knife or ordinary wire cutters. Don't buy the $3 K-mart "combo stripper, crimper and bottle opener" types. You should expect to pay $15 to $20 for a good "plier-type" pair. It will have sized stripping holes, and won't nick or grab the wire - it should be easy to strip wire with it. One model has a small hole in the blade for forming exact wire loops for screw terminals. There are fancier types (autostrip/cut), but they generally aren't necessary, and pros usually don't use them. A pair of diagonal side cutter pliers are useful for clipping ends in constricted places. Don't use these for stripping wire. You will need linesman pliers for twisting wires for wire nuts. You should have a pair of needle-nose pliers for fiddling inside boxes and closing loops, but it's better to form wire loops with a "loop former hole" on your wire stripper - more accurate. If you're using non-metallic cable, get a cable stripper for removing the sheath. Or, do what some pros do, they nick the end of the sheath, grab the ground wire with a pair of pliers, and simply rip the sheath back using the ground wire as a "zipper", and cut the sheath off. You shouldn't try to strip the sheath with a knife point, because it's too easy to slash the insulation on the conductors. Apparently Stanley utility knives fitted with linoleum cutters (hooked blades) can be used to strip sheath, but there is still the possibility that you'll gouge the conductors. For any substantial amount of work with armored cable, it's well worth your while to invest in a rotary cable splitter (~US$ 18). Hack saws are tricky to use without cutting into the wire or the insulation. Three-prong outlet testers are a quick check for properly-wired outlets. About $6. Multimeters tell you more, but are a lot more expensive, and probably not worth it for most people. A simple voltage sensor, which can detect potential through an insulated wire not supplying any devices, is extremely helpful; they cost about US$ 10 at Radio Shack. You should have a voltage detector - to check that the wires are dead before doing work on them. Neon-bulb version are cheap ($2-3) and work well. If you get more serious, a "audible alarm" type is good for tracing circuits without a helper. (Though I've been known to lock the drill on, and hit breakers until the scream stops ;-) For running wires through existing walls, you need fish tape. Often, two tapes are needed, though sometimes, a bent hanger or a length of thin chain will suffice. Fish tapes can be rented. Electrical tape. Lots of it ;-) Seriously, a good and competent wiring job will need very little tape. The tape is useful for wrapping dicy insulation in repair work. Another use is to wrap around the body of outlets and switches to cover the termination screws - I don't do this, but drywall contractors prefer it (to prevent explosions when the drywall knife collides with a live outlet that has no cover plate). Subject: What is UL listing? The UL stands for "Underwriters Laboratory". It used to be an Insurance Industry organization, but now it is independent and non-profit. It tests electrical components and equipment for potential hazards. When something is UL-listed, that means that the UL has tested the device, and it meets their requirements for safety - ie: fire or shock hazard. It doesn't necessarily mean that the device actually does what it's supposed to, just that it probably won't kill you. The UL does not have power of law in the U.S. -- you are permitted to buy and install non-UL-listed devices. However, insurance policies sometimes have clauses in them that will limit their liability in case of a claim made in response to the failure of a non-UL-listed device. Furthermore, in many situations the NEC will require that a wiring component used for a specific purpose is UL-listed for that purpose. Indirectly, this means that certain parts of your wiring must be UL-listed before an inspector will approve it and/or occupancy permits issued. Subject: What is CSA approval? Every electrical device or component must be certified by the Canadian Standards Association before it can be sold in Canada. Implicit in this is that all wiring must be done with CSA-approved materials. They perform testing similar to the UL (a bit more stringent), except that CSA approval is required by law. Again, like the UL, if a fire was caused by non-CSA-approved equipment, your insurance company may not have to pay the claim. In Canada, there is a branch organization of the UL, called ULC (UL of Canada). ULC does not have power of law, and seems to be more a liason group between the CSA and insurance companies. Subject: Are there any cheaper, easier to read books on wiring? USA: The following three books were suggested by our readers Residential Wiring by Jeff Markell, Craftsman Books, Carlsbad CA for $18.25. ISBN 0-934041-19-9. Practical Electrical Wiring Residential, Farm and Industrial, Based on the National Electrical Code ANSI/NFPA 70 Herbert P. Richter and W. Creighton Schwan McGraw-Hill Book Co. Wiring Simplified H. P. Richter and W. C. Schwan Park Publishing Co. Try to make sure that the book is based on the latest NEC revision. Which is currently 1990. Canada: P.S. Knight authors and publishes a book called "Electrical Code Simplified". There appears to be a version published specific to each province, and is very tied into the appropriate provincial code. It focuses on residential wiring, and is indispensible for Canadian DIY'ers. It is better to get this book than the CEC unless you do a lot of wiring (or answer questions on the net ;-). It is updated each time the provincial codes are. This book is available at all DIY and hardware stores for less than C$10. Subject: Inspections how and what? Why should I get my wiring inspected? Most jurisdictions require that you obtain a permit and inspections of any wiring that is done. Amongst other more mundane bureaucratic reasons (like insurance companies not liking to have to pay claims), a permit and inspections provides some assurance that you, your family, your neighbors or subsequent owners of your home don't get killed or lose their homes one night due to a sloppy wiring job. Most jurisdictions have the power to order you to vacate your home, or order you to tear out any wiring done without a permit. California, for instance, is particularly nasty about this. If fire starts in your home, and un-inspected wiring is at fault, insurance companies will often refuse to pay the damage claims. In general, the process goes like this: - you apply to your local inspections office or building department for a permit. You should have a sketch or detailed drawing of what you plan on doing. This is a good time to ask questions on any things you're not sure of. If you're doing major work, they may impose special conditions on you, require loading calculations and ask other questions. At this point they will tell you which inspections you will need. - If you're installing a main panel, you will need to have the panel and service connections inspected before your power utility will provide a connection. This is sometimes done by the local power authority rather than the usual inspectors. - After installing the boxes and wiring, but before the insulation/walls go up, you will need a "rough-in" inspection. - After the walls are up, and the wiring is complete, you will need a "final inspection". Subject: My house doesn't meet some of these rules and regulations. Do I have to upgrade? In general, there is no requirement to upgrade older dwellings, though there are some exceptions (ie: smoke detectors in some cases). However, any new work must be done according to the latest electrical code. Also, if you do ``major'' work, you may be required to upgrade certain existing portions or all of your system. Check with your local electrical inspector. Subject: A word on voltages: 110/115/117/120/125/220/240 One thing where things might get a bit confusing is the different numbers people bandy about for the voltage of a circuit. One person might talk about 110V, another 117V or another 120V. These are all, in fact, exactly the same thing... In North America the utility companies are required to supply a split-phase 240 volt (+-5%) feed to your house. This works out as two 120V +- 5% legs. Additionally, since there are resistive voltage drops in the house wiring, it's not unreasonable to find 120V has dropped to 110V or 240V has dropped to 220V by the time the power reaches a wall outlet. Especially at the end of an extension cord or long circuit run. For a number of reasons, some historical, some simple personal orneryness, different people choose call them by slightly different numbers. This FAQ has chosen to be consistent with calling them "110V" and "220V", except when actually saying what the measured voltage will be. Confusing? A bit. Just ignore it. One thing that might make this a little more understandable is that the nameplates on equipment ofen show the lower (ie: 110V instead of 120V) value. What this implies is that the device is designed to operate properly when the voltage drops that low. 208V is *not* the same as 240V. 208V is the voltage between phases of a 3-phase "Y" circuit that is 120V from neutral to any hot. 480V is the voltage between phases of a 3-phase "Y" circuit that's 277V from hot to neutral. In keeping with 110V versus 120V strangeness, motors intended to run on 480V three phase are often labelled as 440V... Subject: What does an electrical service look like? There are logically four wires involved with supplying the main panel with power. Three of them will come from the utility pole, and a fourth (bare) wire comes from elsewhere. The bare wire is connected to one or more long metal bars pounded into the ground, or to a wire buried in the foundation, or sometimes to the water supply pipe (has to be metal, continuous to where the main water pipe entering the house. Watch out for galvanic action conductivity "breaks" (often between copper and iron pipe)). This is the "grounding conductor". It is there to make sure that the third prong on your outlets is connected to ground. This wire normally carries no current. One of the other wires will be white (or black with white or yellow stripes, or sometimes simply black). It is the neutral wire. It is connected to the "centre tap" (CEC; "center tap" in the NEC) of the distribution transformer supplying the power. It is connected to the grounding conductor in only one place (often inside the panel). The neutral and ground should not be connected anywhere else. Otherwise, weird and/or dangerous things may happen. Furthermore, there should only be one grounding system in a home. Some codes require more than one grounding electrode. These will be connected together, or connected to the neutral at a common point - still one grounding system. Adding additional grounding electrodes connected to other portions of the house wiring is unsafe and contrary to code. If you add a subpanel, the ground and neutral are usually brought as separate conductors from the main panel, and are not connected together in the subpanel (ie: still only one neutral-ground connection). However, in some situations (certain categories of separate buildings) you actually do have to provide a second grounding electrode - consult your inspector. The other two wires will usually be black, and are the "hot" wires. They are attached to the distribution transformer as well. The two black wires are 180 degrees out of phase with each other. This means if you connect something to both hot wires, the voltage will be 220 volts. If you connect something to the white and either of the two blacks you will get 110V. Some panels seem to only have three wires coming into them. This is either because the neutral and ground are connected together at a different point (eg: the meter or pole) and one wire is doing dual-duty as both neutral and ground, or in some rare occasions, the service has only one hot wire (110V only service). Subject: What is a circuit? Inside the panel, connections are made to the incoming wires. These connections are then used to supply power to selected portions of the home. There are three different combinations: 1) one hot, one neutral, and ground: 110V circuit. 2) two hots, no neutral, and ground: 220V circuit. 3) two hots, neutral, and ground: 220V circuit + neutral, and/or two 110V circuits with a common neutral. (1) is used for most circuits supplying receptacles and lighting within your house. (3) is usually used for supplying power to major appliances such as stoves, and dryers - they often have need for both 220V and 110V, or for bringing several circuits from the panel box to a distribution point. (2) is usually for special 220V motor circuits, electric heaters, or air conditioners. [Note: In the US, the NEC frequently permits a circuit similar to (2) be used for stoves and dryers - namely, that there are two hot wires, and a wire that does dual duty as neutral and ground, and is connected to the frame as well as providing the neutral for 110V purposes - three prong plugs instead of four (*only* for stoves/dryers connected to the main panel. When connected to most sub-panels, 4 prong plugs and receptacles are required). In our not-so-humble opinion this is crazy, but the NFPA claims that this practice was re-evaluated for the 1992 NEC, and found to be safe. Check your local codes, or inquire as to local practice -- there are restrictions on when this is permissible.] (1) is usually wired with three conductor wire: black for hot, white for neutral, and bare for grounding. (2) and (3) have one hot wire coloured red, the other black, a bare wire for grounding, and in (3) a white wire for neutral. You will sometimes see (2) wired with just a black, white and ground wire. Since the white is "hot" in this case, both the NEC and CEC requires that the white wire be "permanently marked" at the ends to indicate that it is a live wire. Usually done with paint, nail polish or sometimes electrical tape. Each circuit is attached to the main wires coming into the panel through a circuit breaker or fuse. There are, in a few locales, circuits that look like (1), (2) or (3) except that they have two bare ground wires. Some places require this for hot tubs and the like (one ground is "frame ground", the other attaches to the motor). This may or may not be an alternative to GFCI protection. Subject: "grounding" versus "grounded" versus "neutral". According to the terminology in the CEC and NEC, the "grounding" conductor is for the safety ground, i.e., the green or bare wire. The word "neutral" is reserved for the white when you have a circuit with more than one "hot" wire. Since the white wire is connected to neutral and the grounding conductor inside the panel, the proper term is "grounded conductor". However, the potential confusion between "grounded conductor" and "grounding conductor" can lead to potentially lethal mistakes - you should never use the bare wire as a "grounded conductor" or white wire as the "grounding conductor", even though they are connected together in the panel. [But not in subpanels - subpanels are fed neutral and ground separately from the main panel. Usually.] In the trade, and in common usage, the word "neutral" is used for "grounded conductor". This FAQ uses "neutral" simply to avoid potential confusion. We recommend that you use "neutral" too. Thus the white wire is always (except in some light switch applications) neutral. Not ground. Subject: What does a fuse or breaker do? What are the differences? Fuses and circuit breakers are designed to interrupt the power to a circuit when the current flow exceeds safe levels. For example, if your toaster shorts out, a fuse or breaker should "trip", protecting the wiring in the walls from melting. As such, fuses and breakers are primarily intended to protect the wiring -- UL or CSA approval supposedly indicates that the equipment itself won't cause a fire. Fuses contain a narrow strip of metal which is designed to melt (safely) when the current exceeds the rated value, thereby interrupting the power to the circuit. Fuses trip relatively fast. Which can sometimes be a problem with motors which have large startup current surges. For motor circuits, you can use a "time-delay" fuse (one brand is "fusetron") which will avoid tripping on momentary overloads. A fusetron looks like a spring-loaded fuse. A fuse can only trip once, then it must be replaced. Breakers are fairly complicated mechanical devices. They usually consist of one spring loaded contact which is latched into position against another contact. When the current flow through the device exceeds the rated value, a bimetallic strip heats up and bends. By bending it "trips" the latch, and the spring pulls the contacts apart. Circuit breakers behave similarly to fusetrons - that is, they tend to take longer to trip at moderate overloads than ordinary fuses. With high overloads, they trip quickly. Breakers can be reset a finite number of times - each time they trip, or are thrown when the circuit is in use, some arcing takes place, which damages the contacts. Thus, breakers should not be used in place of switches unless they are specially listed for the purpose. Neither fuses nor breakers "limit" the current per se. A dead short on a circuit can cause hundreds or sometimes even thousands of amperes to flow for a short period of time, which can often cause severe damage. Subject: Breakers? Can't I use fuses? Statistics show that fuse panels have a significantly higher risk of causing a fire than breaker panels. This is usually due to the fuse being loosely screwed in, or the contacts corroding and heating up over time, or the wrong size fuse being installed, or the proverbial "replace the fuse with a penny" trick. Since breakers are more permanently installed, and have better connection mechanisms, the risk of fire is considerably less. Fuses are prone to explode under extremely high overload. When a fuse explodes, the metallic vapor cloud becomes a conducting path. Result? from complete meltdown of the electrical panel, melted service wiring, through fires in the electrical distribution transformer and having your house burn down. Breakers don't do this. Many jurisdictions, particularly in Canada, no longer permit fuse panels in new installations. The NEC does permit new fuse panels in some rare circumstances (requiring the special inserts to "key" the fuseholder to specific size fuses) Some devices, notably certain large air conditioners, require fuse protection in addition to the breaker at the panel. The fuse is there to protect the motor windings from overload. Check the labeling on the unit. This is usually only on large permanently installed motors. The installation instructions will tell you if you need one. Subject: What size wire should I use? For a 20 amp circuit, use 12 gauge wire. For a 15 amp circuit, you can use 14 gauge wire (in most locales). For a long run, though, you should use the next larger size wire, to avoid voltage drops. 12 gauge is only slightly more expensive than 14 gauge, though it's stiffer and harder to work with. Here's a quick table for normal situations. Go up a size for more than 100 foot runs, when the cable is in conduit, or ganged with other wires in a place where they can't dissipate heat easily: Gauge Amps 14 15 12 20 10 30 8 40 6 65 We don't list bigger sizes because it starts getting very dependent on the application and precise wire type. Subject: Where do these numbers come from? There are two considerations, voltage drop and heat buildup. The smaller the wire is, the higher the resistance is. When the resistance is higher, the wire heats up more, and there is more voltage drop in the wiring. The former is why you need higher-temperature insulation and/or bigger wires for use in conduit; the latter is why you should use larger wire for long runs. Neither effect is very significant over very short distances. There are some very specific exceptions, where use of smaller wire is allowed. The obvious one is the line cord on most lamps. Don't try this unless you're certain that your use fits one of those exceptions; you can never go wrong by using larger wire. Subject: What does "14-2" mean? This is used to describe the size and quantity of conductors in a cable. The first number specifies the gauge. The second the number of current carrying conductors in the wire - but remember there's usually an extra ground wire. "14-2" means 14 gauge, two insulated current carrying wires, plus bare ground. -2 wire usually has a black, white and bare ground wire. Sometimes the white is red instead for 220V circuits without neutral. In the latter case, the sheath is usually red too. -3 wire usually has a black, red, white and bare ground wire. Usually carrying 220V with neutral. Subject: What is a "wirenut"/"marrette"/"marr connector"? How are they used? A wire nut is a cone shaped threaded plastic thingummy that's used to connect wires together. "Marrette" or "Marr connector" are trade names. You'll usually use a lot of them in DIY wiring. In essence, you strip the end of the wires about an inch, twist them together, then twist the wirenut on. Though some wirenuts advertise that you don't need to twist the wire, do it anyways - it's more mechanically and electrically secure. There are many different sizes of wire nut. You should check that the wire nut you're using is the correct size for the quantity and sizes of wire you're connecting together. Don't just gimble the wires together with a pair of pliers or your fingers. Use a pair of blunt nose ("linesman") pliers, and carefully twist the wires tightly and neatly. Sometimes it's a good idea to trim the resulting end to make sure it goes in the wirenut properly. Some people wrap the "open" end of the wirenut with electrical tape. This is probably not a good idea - the inspector may tear it off during an inspection. It's usually done because a bit of bare wire is exposed outside the wire nut - instead of taping it, the connection should be redone. Subject: What is a GFI/GFCI? A GFCI is a ``ground-fault circuit interrupter''. It measures the current current flowing through the hot wire and the neutral wire. If they differ by more than a few milliamps, the presumption is that current is leaking to ground via some other path. This may be because of a short circuit to the chassis of an appliance, or to the ground lead, or through a person. Any of these situations is hazardous, so the GFCI trips, breaking the circuit. GFCIs do not protect against all kinds of electric shocks. If, for example, you simultaneously touched the hot and neutral leads of a circuit, and no part of you was grounded, a GFCI wouldn't help. All of the current that passed from the hot lead into you would return via the neutral lead, keeping the GFCI happy. The two pairs of connections on a GFCI outlet are not symmetric. One is labeled LOAD; the other, LINE. The incoming power feed *must* be connected to the LINE side, or the outlet will not be protected. The LOAD side can be used to protect all devices downstream from it. Thus, a whole string of outlets can be covered by a single GFCI outlet. Subject: Where should GFCIs be used? The NEC mandates GFCIs for 110V, 15A or 20A single phase outlets, in bathrooms, kitchens within 6' of the sink, garages, unfinished basements or crawl spaces, outdoors, near a pool, or just about anywhere else where you're likely to encounter water or dampness. There are exceptions for inaccessible outlets, those dedicated to appliances ``occupying fixed space'', typically refrigerators and freezers, and for sump pumps and laundry appliances. The CEC does not mandate as many GFCIs. In particular, there is no requirement to protect kitchen outlets, or most garage or basement outlets. Basement outlets must be protected if you have a dirt floor, garage outlets if they're near the door to outside. Bathrooms and most exterior outlets must have GFCIs. Even if you are not required to have GFCI protection, you may want to consider installing it anyway. Unless you need a GFCI breaker (see below), the cost is low. In the U.S., GFCI outlets can cost as little as US$8. (Costs are a bit higher in Canada: C$12.) Evaluate your own risk factors. Does your finished basement ever get wet? Do you have small children? Do you use your garage outlets to power outdoor tools? Does water or melted snow ever puddle inside your garage? Subject: Where shouldn't I use a GFCI? GFCIs are generally not used on circuits that (a) don't pose a safety risk, and (b) are used to power equipment that must run unattended for long periods of time. Refrigerators, freezers, and sump pumps are good examples. The rationale is that GFCIs are sometimes prone to nuisance trips. Some people claim that the inductive delay in motor windings can cause a momentary current imbalance, tripping the GFCI. Note, though, that most GFCI trips are real; if you're getting a lot of trips for no apparent reason, you'd be well-advised to check your wiring before deciding that the GFCI is broken or useless. Subject: What is the difference between a GFCI outlet and a GFCI breaker? For most situations, you can use either a GFCI outlet as the first device on the circuit, or you can install a breaker with a built-in GFCI. The former is generally preferred, since GFCI breakers are quite expensive. For example, an ordinary GE breaker costs ~US$5; the GFCI model costs ~US$35. There is one major exception: if you need to protect a ``multi-wire branch circuit'' (two or more circuits sharing a common neutral wire), such as a Canadian-style kitchen circuit, you'll need a multi-pole GFCI breaker. Unfortunately, these are expensive; the cost can range into the hundreds of dollars, depending on what brand of panel box you have. But if you must protect such a circuit (say, for a pool heater), you have no choice. One more caveat -- GFCI outlets are bulky. You may want to use an oversize box when installing them. On second thought, use large (actually deep) boxes everywhere. You'll thank yourself for it. Incidentally, if you're installing a GFCI to ensure that one specific outlet is protected (such as a bathroom), you don't really have to go to all of the trouble to find the first outlet in the circuit, you could simply find the first outlet in the bathroom, and not GFCI anything upstream of it. But protecting the whole circuit is preferred. When you install a GFCI, it's a good idea to use the little "ground fault protected" stickers that come with it and mark the outlets downstream of the GFCI. You can figure out which outlets are "downstream", simply by tripping the GFCI with the test button and see which outlets are dead. Subject: What's the purpose of the ground prong on an outlet, then? Apart from their use in electronics, which we won't comment on, and for certain fluorescent lights (they won't turn on without a good ground connection), they're intended to guard against insulation failures within the device. Generally, the case of the appliance is connected to the ground lead. If there's an insulation failure that shorts the hot lead to the case, the ground lead conducts the electricity away safely (and possibly trips the circuit breaker in the process). If the case is not grounded and such a short occurs, the case is live -- and if you touch it while you're grounded, you'll get zapped. Of course, if the circuit is GFCI-protected, it will be a very tiny zap -- which is why you can use GFCIs to replace ungrounded outlets (both NEC and CEC). There are some appliances that should *never* be grounded. In particular, that applies to toasters and anything else with exposed conductors. Consider: if you touch the heating electrode in a toaster, and you're not grounded, nothing will happen. If you're slightly grounded, you'll get a small shock; the resistance will be too high. But if the case were grounded, and you were holding it, you'd be the perfect path to ground... Subject: Why is one prong wider than the other? Polarization Nowadays, many two-prong devices have one prong wider than the other. This is so that the device could rely (not guaranteed!) on one specific wire being neutral, and the other hot. This is particularly advantageous in light fixtures, where the the shell should neutral (safety), or other devices which want to have an approximate ground reference (ie: some radios). Most 2-prong extension cords have wide prongs too. This requires that you wire your outlets and plugs the right way around. You want the wide prong to be neutral, and the narrow one hot. Most outlets have a darker metal for the hot screw, and lighter coloured screw for the neutral. If not, you can usually figure out which is which by which prong the terminating screw connects to. Subject: What kind of outlets do I need in a kitchen? The NEC requires at least two 20 amp ``small appliance circuits'' for kitchens. The CEC requires split-duplex receptacles. Outlets must be installed such that no point is more than 24" (NEC) (900 mm CEC) from an outlet. Every counter wider than 12" (NEC) or 300 mm (CEC) must have at least one outlet. The circuit these outlets are on may not feed any outlets except in the kitchen, pantry, or dining room. Furthermore, these circuits are in addition to any required for refrigerators, stoves, microwaves, lighting, etc. Non-dedicated outlets within 6' of a sink *must* be protected by a GFCI (NEC only). Split duplex receptacles are fed with a 220V circuit. The tab is broken on the hot side of the outlet, and one hot goes to the upper outlet, and the other hot goes to the lower outlet. The neutral connects to both outlets through one screw. When "carrying through" to another outlet, the neutral must be pigtailed, such that removing the outlet, or having the neutral connection fall off doesn't cause the neutral to disconnect from downstream outlets. Subject: Where must outlets and switches be in bathrooms? There must be at least one outlet in each bathroom, adjacent to the sink, in addition to any outlet that may be incorporated in the light fixture. All such outlets *must* be GFCI-protected. Subject: What is Romex/NM/NMD? What is BX? When should I use each? Romex is a brand name for a type of plastic insulated wire. Sometimes called non-metallic sheath. The formal name is NM. This is suitable for use in dry, protected areas (ie: inside stud walls, on the sides of joists etc.), that are not subject to mechanical damage or excessive heat. Most newer homes are wired almost exclusively with NM wire. There are several different categories of NM cable. BX cable -- technically known as armored cable or "AC" has a flexible aluminum or steel sheath over the conductors and is fairly resistant to damage. TECK cable is AC with an additional external thermoplastic sheath. Protection for cable in concealed locations: where NM or AC cable is run through studs, joists or similar wooden members, the outer surface of the cable must be kept at least 32mm/1.25" (CEC & NEC) from the edges of the wooden members, or the cable should be protected from mechanical injury. This latter protection can take the form of metal plates (such as spare outlet box ends) or conduit. [Note: inspector-permitted practise in Canada suggests that armored cable, or flexible conduit can be used as the mechanical protection, but this is technically illegal.] Additional protection recommendations (these are rules in the Canadian codes - they are reasonable answers to the vague references to "exposed to mechanical damage" in both the NEC and CEC): - NM cable should be protected against mechanical damage where it passes through floors or on the surface of walls in exposed locations under 5 feet from the floor. Ie: use AC instead, flexible conduit, wooden guards etc. - Where cable is suspended, as in, connections to furnaces or water heaters, the wire should be protected. Canadian practise is usually to install a junction or outlet box on the wall, and use a short length of AC cable or NM cable in flexible conduit to "jump" to the appliance. Stapling NM to a piece of lumber is also sometimes used. - Where NM cable is run in close proximity to heating ducts or pipe, heat transfer should be minimized by means of a 25mm/1" air space, or suitable insulation material (a wad of fiberglass). - NM cable shall be supported within 300mm/1' of every box or fitting, and at intervals of no more than 1.5m/5'. Holes in joists or studs are considered "supports". Some slack in the cable should be provided adjacent to each box. [while fishing cable is technically in violation, it is permitted where "proper" support is impractical] - 2 conductor NM cable should never be stapled on edge. [Knight also insists on only one cable per staple, referring to the "workmanship" clause, but this seems more honoured in the breach...] - cable should never be buried in plaster, cement or similar finish. - cable should be protected where it runs behind baseboards. - Cable may not be run on the upper edge of ceiling joists or the lower edges of rafters where the headroom is more than 1m (39"). Whenever BX cable is terminated at a box with a clamp, small plastic bushings must be inserted in the end of the cable to prevent the clamps forcing the sharp ends of the armor through the insulation. BX is sometimes a good idea in a work shop unless covered by solid wall coverings. In places where damage is more likely (like on the back wall of a garage ;-), you may be required to use conduit, a UL- (or CSA-) approved metal pipe. You use various types of fittings to join the pipe or provide entrance/exit for the wire. Service entrances frequently use a plastic conduit. In damp places (eg: buried wiring to outdoor lighting) you will need special wire (eg: CEC NMW90, NEC UF). NMW90 looks like very heavy-duty NMD90. You will usually need short lengths of conduit where the wire enters/exits the ground. [See underground wiring section.] Thermoplastic sheath wire (such as NM, NMW etc.) should not be exposed to direct sunlight unless explicitly approved for that purpose. Many electrical codes do not permit the routing of wire through furnace ducts, including cold air return plenums constructed by metal sheeting enclosing joist spaces. The reason for this is that if there's a fire, the ducting will spread toxic gasses from burning insulation very rapidly through the building. Teflon insulated wire is permitted in plenums in many areas. Canada appears to use similar wire designations to the US, except that Canadian wire designations usually include the temperature rating in Celsius. Eg: "AC90" versus "AC". In the US, NM-B is 90 degrees celcius. NOTE: local codes vary. This is one of the items that changes most often. Eg: Chicago codes require conduit *everywhere*. There are very different requirements for mobile homes. Check your local codes, *especially* if you're doing anything that's the slightest out of the ordinary.

The NEC permits use of plastic boxes with non-metallic cable only. The reasoning is simple -- with armored cable, the box itself provides ground conductor continuity. U.S. plastic boxes don't use metal cable clamps. The CEC is slightly different. The CEC never permits cable armor as a grounding conductor. However, you must still provide ground continuity for metallic sheath. The CEC also requires grounding of any metal cable clamps on plastic boxes. The advantage of plastic boxes is comparatively minor even for non-metallic sheathed cable -- you can avoid making one ground connection and they sometimes cost a little less. On the other hand, plastic boxes are more vulnerable to impacts. For exposed or shop wiring, metal boxes are probably better. Subject: Junction box positioning? A junction box is a box used only for connecting wires together. Junction boxes must be located in such a way that they're accessible later. Ie: not buried under plaster. Excessive use of junction boxes is often a sign of sloppy installation, and inspectors may get nasty. Subject: Can I install a replacement light fixture? In general, one can replace fixtures freely, subject to a few caveats. First, of course, one should check the amperage rating of the circuit. If your heart is set on installing half a dozen 500 watt floodlights, you may need to run a new wire back to the panel box. But there are some more subtle constraints as well. For example, older house wiring doesn't have high-temperature insulation. The excess heat generated by a ceiling-mounted lamp can and will cause the insulation to deteriorate and crack, with obvious bad results. Some newer fixtures are specifically marked for high temperature wire only. (You may find, in fact, that your ceiling wiring already has this problem, in which case replacing any devices is a real adventure.) Other concerns include providing a suitable ground for some fluorescent fixtures, and making sure that the ceiling box and its mounting are strong enough to support the weight of a heavy chandelier or ceiling fan. You may need to install a new box specifically listed for this purpose. A 2x4 across the ceiling joists makes a good support. Metal brackets are also available that can be fished into ceilings thru the junction box hole and mounted between the joists. There are special rules for recessed light fixtures such as "pot" lamps or heat lamps. When these are installed in insulated ceilings, they can present a very substantial fire hazard. The CEC provides for the installation of pot lamps in insulated ceilings, provided that the fixture is boxed in a "coffin" (usually 8'x16"x12" - made by making a pair of joists 12" high, and covering with plywood) that doesn't have any insulation. (Yes, that's 8 *feet* long) NEC rules are somewhat less stringent. They require at least 3" clearance between the fixture and any sort of thermal insulation. The rules also say that one should not obstruct free air movement, which means that a CEC-style ``coffin'' might be worthwhile. Presumably, that's up to the local inspector. [The CEC doesn't actually mandate the coffin per-se, this seems to be an inspector requirement to make absolutely certain that the fixture can't get accidentally buried in insulation. Ie: if you have insulation blown in later.] There are now fixtures that contain integral thermal cutouts and fairly large cases that can be buried directly in insulation. They are usually limited to 75 watt bulbs, and are unfortunately, somewhat more expensive than the older types. Before you use them, you should ensure that they have explicit UL or CSA approval for such uses. Follow the installation instructions carefully; the prescribed location for the sensor can vary. There does not yet appear to be a heat lamp fixture that is approved for use in insulation. The "coffin" appears the only legal approach. Subject: What does it mean when the lights brighten when a motor starts? This usually means that the neutral wire in the panel is loose. Depending on the load balance, one hot wire may end up being more than 110V, and the other less than 110V, with respect to ground. This is a very hazardous situation - it can destroy your electronic equipment, possibly start fires, and in some situations electrocute you (ie: some US jurisdictions require the stove frame connected to neutral). If this happens, contact your electrical authority immediately and have them come and check out the problem. Note: a brief (< 1 second) brightening is sometimes normal with lighting and motors on the same 220V with neutral circuit. A loose main panel neutral will usually show increased brightness far longer than one second. In case of doubt, get help. Subject: What is 3 phase power? Should I use it? Can I get it in my house? Three phase power has three "hot" wires, 120 degrees out of phase with each other. These are usually used for large motors because it is more "efficient", provides a bit more starting torque, and because the motors are simpler and hence cheaper. You're most likely to encounter a 3 phase circuit that shows 110 volts between any hot and ground, and 208 volts between any two hots. The latter shows the difference between a normal 220V/110V common neutral circuit, which is 240 volts between the two hots. There are 3 phase circuits with different voltages. Bringing in a 3 phase feed to your house is usually ridiculously expensive, or impossible. If the equipment you want to run has a standard motor mount, it is *MUCH* cheaper to buy a new 110V or 220V motor for it. In some cases it is possible to run 3 phase equipment on ordinary power if you have a "capacitor start" unit, or use a larger motor as a (auto-)generator. These are tricky, but are a good solution if the motor is non-standard size, or too expensive or too big to replace. The Taunton Press book ``The Small Shop'' has an article on how to do this if you must. Note that you lose any possible electrical efficiency by using such a converter. The laws of thermodynamics guarantee that. Subject: Is it better to run motors at 110 or 220? Theoretically, it doesn't make any difference. However, there is a difference is the amount of power lost in the supply wiring. All things being equal, a 220V motor will lose 4 times less power in the house wiring than a 110V motor. This also means that the startup surge loss will be less, and the motor will get to speed quicker. And in some circumstances, the smaller power loss will lead to longer motor life. This is usually irrelevant unless the supply wires are more than 50 feet long. Subject: What is this nonsense about 3HP on 110V 15A circuits? It is a universal physical law that 1 HP is equal to 746 watts. Given heating loss, power factor and other inefficiencies, it is usually best to consider 1 HP is going to need 1000-1200 watts. A 110V 15A circuit can only deliver 1850 watts to a motor, so it cannot possibly be more than approximately 2 HP. Given rational efficiency factors, 1.5HP is more like it. Some equipment manufacturers (Sears in particular, most router manufacturers in general ;-) advertise a HP rating that is far in excess of what is possible. They are giving you a "stall horsepower" or similar. That means the power is measured when the motor is just about to stop turning because of the load. What they don't mention is that if you kept it in that condition for more than a few seconds hopefully your breaker will trip, otherwise the motor will melt -- it's drawing far more current than it can continuously. When comparing motors, compare the continuous horsepower. This should be on the motor nameplate. If you can't find that figure, check the amperage rating, which is always present. Subject: How do I convert two prong receptacles to three prong? Older homes frequently have two-prong receptacles instead of the more modern three. These receptacles have no safety ground, and the cabling usually has no ground wire. Neither the NEC or CEC permits installing new 2 prong receptacles anymore. There are several different approaches to solving this: 1) If the wiring is done through conduit or BX, and the conduit is continuous back to the panel, you can connect the third prong of a new receptacle to the receptacle box. NEC mainly - CEC frowns on this practise. 2) If there is a copper cold water pipe going nearby, and it's continuous to the main house ground point, you can run a conductor to it from the third prong. 3) Run a ground conductor back to the main panel. 4) Easiest: install a GFCI receptacle. The ground lug should not be connected to anything, but the GFCI protection itself will serve instead. The GFCI will also protect downstream (possibly also two prong outlets). If you do this to protect downstream outlets, the grounds must not be connected together. Since it wouldn't be connected to a real ground, a wiring fault could energize the cases of 3 prong devices connected to other outlets. Be sure, though, that there aren't indirect ground plug connections, such as via the sheath on BX cable. The CEC permits you to replace a two prong receptacle with a three prong if you fill the U ground with a non-conducting goop. Like caulking compound. This is not permitted in the NEC. Subject: Are you sure about GFCIs and ungrounded outlets? Should the test button work? We're sure about what the NEC and CEC say. Remember, though, that your local codes may vary. As for the TEST button -- there's a resistor connecting the LOAD side of the hot wire to the LINE side of the neutral wire when you press the TEST button. Current through this resistor shows up as an imbalance, and trips the GFCI. This is a simple, passive, and reliable test, and doesn't require a real ground to work. If your GFCI does not trip when you press the TEST button, it is very probably defective or miswired. Again: if the test button doesn't work, something's broken, and potentially dangerous. The problem should be corrected immediately. The instructions that come with some GFCIs specify that the ground wire must be connected. We do not know why they say this. The causes may be as mundane as an old instruction sheet, or with the formalities of UL or CSA listing -- perhaps the device was never tested without the ground wire being connected. On the other hand, UL or CSA approval should only have been granted if the device behaves properly in *all* listed applications, including ungrounded outlet replacement. (One of us called Leviton; their GFCIs are labeled for installation on grounded circuits only. The technician was surprised to see that; he agreed that the NEC does not require it, and promised to investigate.) Subject: How should I wire my shop? As with any other kind of wiring, you need enough power for all devices that will be on simultaneously. The code specifies that you should stay under 80% of the nominal capacity of the circuit. For typical home shop use, this means one circuit for the major power tools, and possibly one for a dust collector or shop vac. Use at least 12 gauge wire -- many power tools have big motors, with a big start-up surge. If you can, use 20 amp breakers (NEC), though CEC requires standard 20A receptacles which means you'd have to "replug" all your equipment. Lights should either be on a circuit of their own -- and not shared with circuits in the rest of the house -- or be on at least two separate circuits. The idea is that you want to avoid a situation where a blade is still spinning at several thousand RPM, while you're groping in the dark for the OFF switch. Do install lots of outlets. It's easier to install them in the beginning, when you don't have to cut into an existing cable. It's useful if at least two circuits are accessible at each point, so you can run a shop vac or a compressor at the same time as the tool you really want. But use metal boxes and plates, and maybe even metal-sheathed cable; you may have objects flying around at high speeds if something goes a bit wrong. Note that some jurisdictions have a "no horizontal wiring" rule in workshops or other unfinished areas that are used for working. What this means is that all wiring must be run along structural members. Ie: stapled to studs. Other possible shop circuits include heater circuits, 220V circuits for some large tools, and air compressor circuits. Don't overload circuits, and don't use extension cords if you can help it, unless they're rated for high currents. (A coiled extension cord is not as safe as a straight length of wire of the same gauge. Also, the insulation won't withstand as much heat, and heat dissipation is the critical issue.) If your shop is located at some remove from your main panel, you should probably install a subpanel, and derive your shop wiring from it. If you have young children, you may want to equip this panel with a cut-off switch, and possibly a lock. If you want to install individual switches to ``safe'' particular circuits, make sure you get ones rated high enough. For example, ordinary light switches are not safely able to handle the start-up surge generated by a table saw. Buy ``horsepower-rated'' switches instead. Finally, note that most home shops are in garages or unfinished basements; hence the NEC requirements for GFCIs apply. And even if you ``know'' that you'd never use one of your shop outlets to run a lawn mower, the next owner of your house might have a different idea. Note: Fine Woodworking magazine often carries articles on shop wiring. April 1992 is one place to start. Subject: Underground Wiring You will need to prepare a trench to specifications, use special wire, protect the wire with conduit or special plastic tubing and possibly lumber (don't use creosoted lumber, it rots thermoplastic insulation and acts as a catalyst in the corrosion of lead). The transition from in-house to underground wire is generally via conduit. All outdoor boxes must be specifically listed for the purpose, and contain the appropriate gaskets, fittings, etc. If the location of the box is subject to immersion in water, a more serious style of water-proof box is needed. And of course, don't forget the GFCIs. The required depths and other details vary from jurisdiction to jurisdiction, so we suggest you consult your inspector about your specific situation. A hint: buy a roll of bright yellow tape that says "buried power line" and bury it a few inches above where the wire has been placed. Subject: Aluminum wiring During the 1970's, aluminum (instead of copper) wiring became quite popular and was extensively used. Since that time, aluminum wiring has been implicated in a number of house fires, and most jurisdictions no longer permit it in new installations. We recommend, even if you're allowed to, that do not use it for new wiring. But don't panic if your house has aluminum wiring. Aluminum wiring, when properly installed, can be just as safe as copper. Aluminum wiring is, however, very unforgiving of improper installation. We will cover a bit of the theory behind potential problems, and what you can do to make your wiring safe. The main problem with aluminum wiring is a phenomenon known as "cold creep". When aluminum wiring warms up, it expands. When it cools down, it contracts. Unlike copper, when aluminum goes through a number of warm/cool cycles it loses a bit of tightness each time. To make the problem worse, aluminum oxidises, or corrodes when in contact with certain types of metal, so the resistance of the connection goes up. Which causes it to heat up and corrode/ oxidize still more. Eventually the wire may start getting very hot, melt the insulation or fixture it's attached to, and possibly even cause a fire. Since people usually encounter aluminum wiring when they move into a house built during the 70's, we will cover basic points of safe aluminum wiring. We suggest that, if you're considering purchasing a home with aluminum wiring, or have discovered it later, that you hire a licensed electrician or inspector to check over the wiring for the following things: 1) Fixtures (eg: outlets and switches) directly attached to aluminum wiring should be rated for it. The device will be stamped with "Al/Cu" or "CO/ALR". The latter supersedes the former, but both are safe. These fixtures are somewhat more expensive than the ordinary ones. 2) Wires should be properly connected (at least 3/4 way around the screw in a clockwise direction). Connections should be tight. While repeated tightening of the screws can make the problem worse, during the inspection it would pay off to snug up each connection. Note that aluminum wiring is still often used for the main service entrance cable. It should be inspected. 3) "push-in" terminals are an extreme hazard with aluminum wire. Any connections using push-in terminals should be redone with the proper screw connections immediately. 4) There should be no signs of overheating: darkened connections, melted insulation, or "baked" fixtures. Any such damage should be repaired. 5) Connections between aluminum and copper wire need to be handled specially. Current Canadian codes require that the wire nut used must be specially marked for connecting aluminum to copper. The NEC requires that the wire be connected together using special crimp devices, with an anti-oxidant grease. The tools and materials for the latter are quite expensive - not practical to do it yourself unless you can rent the tool. 6) Any non-rated receptacle can be connected to aluminum wiring by means of a short copper "pigtail". See (5) above. 7) Shows reasonable workmanship: neat wiring, properly stripped (not nicked) wire etc. If, when considering purchasing a home, an inspection of the wiring shows no problems or only one or two, we believe that you can consider the wiring safe. If there are signs of problems in many places, we suggest you look elsewhere. If the wrong receptacles are used, you can replace them with the proper type, or use pigtails - having this professionally done can range from $3 to $10 per receptacle/switch. You can do this yourself too. Subject: I'm buying a house! What should I do? Congratulations. But... It's generally a good idea to hire an inspector to look through the house for hidden gotchas. Not just for wiring, but plumbing and structural as well. If an inspection of the wiring shows no problems or only one or two minor ones, we believe that you can consider the wiring safe (after any minor problems are fixed). If there are signs of problems in many places, we suggest you look elsewhere. Here's some hints on what to look for: Obvious non-code wiring can include: - Zip cord wiring, either concealed or nailed to walls - Hot wiring on the identified (neutral) conductor without proper marking. - Ungrounded grounding outlets (except when downstream of a GFCI) - Splices hanging in mid-air (other than proper knob-and-tube) - Switched neutrals - Unsecured Romex swinging about like grapevines Certain wiring practises that are actually to code (or were at one time) sometimes reveal DIY wiring that may have hidden violations: - Switches that seem to control nothing (abandoned, perhaps not properly terminated wiring) - A wall switch that shuts off a group of lights that are separately controlled by other wall switches. (except when it's *really* convenient ;-) - Switches and outlets in bizarre locations - Great numbers of junction boxes without outlets or lamps - Junction boxes with great numbers of wires going into them - Wiring that passes through a closet instead of a wall or ceiling - Backwrapped grounding wires Subject: What is this weird stuff? Old style wiring In the years since Edison "invented" electricity, several different wiring "styles" have come and gone. When you buy an older home you may encounter some of this stuff. This section describes the old methods, and some of their idiosyncrasies. The oldest wiring system you're likely to encounter is called "knob and tube" (K&T). It is made up of individual conductors with a cloth insulation. The wires are run along side structural members (eg: joists or studs) using ceramic stand-offs (knobs). Wire is run through structural members using ceramic tubes. Connections were made by twisting the wire together, soldering, and wrapping with tape. Since the hot and neutral were run separately, the wiring tends to be rather confusing. A neutral often runs down the centre of each room, with "taps" off to each fixture. The hot wire tended to run from one fixture to the next. In some cases K&T isn't colour-coded, so the neutral is often the same colour as the hot wires. You'll see K&T in homes built as late as the 40's. Comments on K&T: - the people installing K&T were pretty paranoid about electricity, so the workmanship tends to be pretty good. - The wire, insulation and insulators tend to stand up very well. Most K&T I've seen, for example, is in quite good condition. - No grounding. Grounding is usually difficult to install. - boxes are small. Receptacle replacement (particularly with GFCI) can be difficult. No bushing on boxes either, so wiring changes need special attention to box entry. - Sometimes the neutral isn't balanced very well between separately hot circuits, so it is sometimes possible to overload the neutral without exceeding the fusing on any circuit. - Building code does not permit insulation in walls that contain K&T. - Connection to existing K&T from new circuits can be tricky. Consult your inspector. - Modern wiring practise requires considerably more outlets to be installed than K&T systems did. Since K&T tends to be in pretty decent condition it generally isn't necessary to replace it simply because it's K&T. What you should watch out for is renovations that have interfered with it and be cautious about circuit loading. In many cases it's perfectly reasonable to leave existing K&T alone, and add new fixtures on new circuits using modern techniques. After K&T, they invented multi-conductor cable. The first type you will see is roughly a cloth and varnish insulation. It looks much like the romex cable of the last decade or two. This stuff was used in the 40's and 50's. Again, no grounding conductor. It was installed much like modern wiring. Its major drawback is that this type of insulation embrittles. We've seen whole systems where the insulation would fracture and fall off at a touch. BX cable of the same vintage has similar problems. This stuff is very fragile, and becomes rather hazardous if the wires become bare. This wiring should be left untouched as much as possible - whenever an opportunity arises, replace it. A simple receptacle or switch replacement can turn into a several hour long frustrating fight with electrical tape or heat-shrink tubing. After this wiring technique, the more modern romex was invented. It's almost a asphalt impregnated cloth. Often a bit sticky. This stuff stands up reasonably well and doesn't present a hazard and is reasonably easy to work with. It does not need to be replaced - it should be considered as safe as the "modern" stuff - thermoplastic insulation wire. Just don't abuse it too much. Subject: Where do I buy stuff? Try to find a proper electrical supply outlet near you. Their prices will often be considerably better than chain hardware stores or DIY centres, have better quality materials, have wider variety including the "odd" stuff, and have people behind the counter that know what you're talking about. Cultivate friendly knowledgeable sales people. They'll give you much valuable information. -- Chris Lewis; clewis@ferret.ocunix.on.ca; Phone: Canada 613 832-0541 Psroff 3.0 info: psroff-request@ferret.ocunix.on.ca Ferret list: ferret-request@ferret.ocunix.on.ca

Heres a story of a Saint that people might like to read. I got it from a The Morning Star, and am posting it with the permission of the editor. Saint Aloysius Gonzaga The Patron of Youth The marquis Gonzaga had high aspirations for his son, the Prince Gonzage. He wanted him to become a famous, brave and honoured soldier. After all, he must carry on the great family name of Gonzaga. Of course, he was to become far more famous, brave and honoured than his father could ever have imagined; though not in the manner expected. Saint Aloysius' mother was a woman who received immense joy from praying to God and meditating on the divine mysteries and the life of Our Lord. She had little time for the pleasures of this life. As Saint Aloysius grew, he began to resemble his mother more than his father. Saint Aloysius had learned numerous expressions from his father's soldiers, but the moment he discovered that they were vulgar, he fainted from shock. This shows his immense hatred of sin (What an example for us of the contempt we must have for sin). About the time of his First Holy Communion (which he received from the Archbishop of Milan, Charles Borromeo, whom himself became a great Saint), he con-secrated his purity to God and asked the Blessed Virgin to protect his innocence for life. He wanted to share Our Lord's suffering to show his reciprocal love. He started by denying his passions; he avoided eating the finest foods, wearing the best clothes, and would put pieces of wood in his bed in order to mortify himself for the love of God. While he was in his early teens his father sent him (and his younger brother) to the court of the Spanish King, Phillip 11. Obediently, he set out to make the best of it. He mixed in well with the people of the royal court, for he was handsome, polite, intelligent and always had something interesting to say. Not long before this time, the great soldier-saint, Saint Igna- tius of Loyola, had founded the Society of Jesus (the Jesuits) towards which Saint Aloysius -12- began to have a yearning. When he finally told his father, the marquis flew into a rage and forbade his son to become a priest. After a short time, his father sent him to the great cities in order that he be tempted away from the priesthood, but even through these trials, Saint Aloysius grew in his desire for the religious life and was strengthened in the virtue of purity. The Marquis' plans were obviously failing, so he con-fronted his son: "Will you or will you not obey me and forget this foolish- ness?" "I will not, father," was the in-evitable reply. "Then leave from my sight and don't return until you change your mind!" With tears clouding his eyes, the Saint left the room to pray: "Tell me Lord, what am I to do? Tell me! Tell me!" He knelt down to flagellate himself as he had done several times before, but this time he was seen. The onlooker rushed to the marquis. This at last brought the proud man to his senses. "The Lord wants him, the Lord can have him." He gave his consent for his son to become a Jesuit. After some years (at the end of the sixteenth century), a terri- ble epidemic broke out in Rome. All the hospitals were full and could house no more, so the Jesuits opened their own. Saint Aloy- sius did all he could in the hospitals, particularly to prepare the dying for a holy death. Saint Aloysius himself contracted the plague from carrying and nursing the sick. For three months he lay with a burning fever and finally, on June 21st, 1591, he gave his soul to the Lord while gazing at a crucifix. Let us invoke Saint Aloysius as our patron and imitate him in his humility, purity and confidence in prayer. Saint Aloysius Gonzaga, pray for us. - Brendan Arthur Prayer is as necessary to a person consecrated to the service of others as a sword is to a soldier God Bless From Simon Lines: 106 -- /----------------------------------------------------------------|-------\ | Simon P.

I recently bought a PLI 21mgbyte floptical drive, and I was very happy with it until I tried to use it to format a 1.4 HD diskette. I put the HD floppy in my Superdrive to check that the floptical had formatted it correctly, and now my Superdrive refuses to recognize ANY floppy (it says "this disk is unreadable" and asks if I want to format it) even original systems floppies from Apple. Nor will it format the disks if I try to ("initialization failed!") Strangely enough the floptical still reads both the 21 MB and 1.4 HD disks, but I cant look at my 800k floppies, and if I have a crash I'm screwed because the Floptical can't be used as a start-up disk. PLI has been unresponsive. Any ideas? Has this happened to anyone before? I was looking for an inexpensive storage solution, and now I am looking at an expensive repair.

------------------------- Original Article ------------------------- The Colorado Daily recently reprinted the Wall Street Journal's article on Paxton Quigley, including the nefarious little paragraph the Journal tacked onto the end. After recieving much assistance from various T.P.G. type folks, I wrote a letter to the editor criticizing this last paragraph, and surprise, surprise, surprise, they published it. The text follows. The Colorado Daily, btw, is the University of Colorado (Boulder) student (I think) newspaper... not exactly a big coup, but every little bit, i guess... (The title was the only thing they changed/added) "Gun Stats" The Daily recently reprinted an article from the Wall Street Journal, primarily concerned with Paxton Quigley, author of "Armed and Female." The article, in turn, cites a misleading statistic that was originally reported in the New England Journal of Medicine. The article states, "A study... found that a gun in the home was 43 times more likely to be used to kill its owner, spouse, a friend, or child than to kill an intruder." This is an often-quoted statistic, and it is misleading for sev- eral reasons, outlined below: The study gives the impression that, if you own a gun, the likelihood that you will successfully use it to defend yourself is less than that of the gun being turned against you. The study, however, fails to take into account cases where a law-abiding citizen uses a gun to thwart a crime, without actually killing the perpe- trator. The study actually refers to 'acquaintances' rather than 'friend'. This would include the friendly neigh- borhood thug who shows up like clockwork, every month, the second your grandmother cashes her social security check. Possibly an acquaintance, but hardly a friend. The NEJM study is based on the immediate dis- position of cases and fails to take into account cases originally filed as homicides that were later ruled to be self-defense. Especially considering the small sample size (396), taking these events into account has a sub- stantial effect on the 43:1 ratio quoted. Criminologist Gary Kleck gives us a slightly dif- erent statistic: a gun is 33 times more likely to be used, successfully, by a private citizen against an aggressor than it is to kill anyone at all. Further, per- sons defending themselves from aggression by using a gun fare better than those who resist vicimization by some other means, or who offer no resistance at all. Statistics available from the FBI and other agencies also show that a gun is 245 times more likely to be used by a non-criminal to defend against criminal threat than to be used to commit criminal homicide, 535 times more likely to be used to defend against a criminal threat than to accidentally kill anybody, and 50 times more likely to defend against criminal threat than to be used to commit suicide. It is well to keep in mind that nearly anything can be proved by uncritical quotation of statistics. One has to consider carefully what questions were asked by those gathering the data before one can draw an accu- rate conclusion from them. D.F.

I hate to pour cold water on this, but currently seawater extracted uranium, even using the new, improved fiber absorbers from Japan, is about 20 times more expensive than uranium on the spot market. Uranium is *very* cheap right now, around $10/lb. Right now, there are mines closing because they can't compete with places like Cigar Lake in Canada (where the ore is so rich they present safety hazards to the mines, who work in shielded vehicles). Plenty of other sources (for example, uranium from phosphate processing) would come on line before uranium reached $200/lb. "Demand and supply balance will collapse" is nonsense. Supply and demand always balance; what changes is the price. Is uranium going to increase in price by a factor of 20 by the end of the century? Not bloody likely. New nuclear reactors are not being built at a sufficient rate. Uranium from seawater is interesting, but it's a long term project, or a project that the Japanese might justify on grounds of self-sufficiency. Paul F. Dietz dietz@cs.rochester.edu

There are two conflicting reports about a pitcher that is either in the Jays' farm system or the Braves'. His name is Bill Taylor. He was picked up by the Jays, but had to be offered back to the Braves before they were able to send him to the Syracuse Chiefs. One report says that the Braves took him back and assigned him to Richmond. The other says that he is on the Chiefs' roster. Which one is right?

Our news feed has been losing a lot of articles lately - so I haven't seen the FAQ lately to check.] Two ways: 1) When you start the xterm, you can use command line options: -n ICON_NAME To set the icon label -T WINDOW_TITLE To set the window title -title WINDOW_TITLE Equivalent to -T WINDOW_TITLE 2) You can use escape sequences to change things on the fly: The basic escape sequence is: ESC ] <P> ; <SOME_ARBITARY_TEXT> BEL where ESC and BEL are the ASCII ESCAPE and BELL characters, <P> is an ASCII decimal digit -- '2', '1', or '0', depending on whether you are trying to set the window or icon title, or both, and <SOME_ARBITARY_TEXT> is your desired label string. Hence, this command will set the window & icon title: echo "\033]0;YOUR_TITLE_GOES_HERE\007\c" To set just the icon title: echo "\033]1;YOUR_TITLE_GOES_HERE\007\c" To set just the window title: echo "\033]2;YOUR_TITLE_GOES_HERE\007\c" Of course, you may have to fiddle with exact syntax, depending on how the echo command works on your system and what shell you are using (I've shown System-V semantics under Bourne or Korn shells). [Hint for Sun OS users: use /usr/5bin/echo instead of /bin/echo or Csh's built-in echo. Otherwise you'll have to embed literal ESC and BEL characters in the string instead of using convenient octal sequences.] If you want your titlebar updated continously, say to show your current directory, hostname, or somesuch, then you'll have to see if you can coerce your shell into spitting out the appropriate escape sequences when it prompts for commands.

But clearly It was a "no-knock", according to the Associated Press report. Here's something I found in my collection: Excerpts from an article in the Knoxville News-Sentinel Final Edition Monday, March 1, 1993 (the byline is associated press): WACO, Texas - Fierce gun battles erupted Sunday as more than 100 law officers tried to arrest the leader of a heavily armed religious cult. At least four federal agents and two cult members were reported killed. [...] The gun battles began when federal agents hidden in livestock trailers stormed the sect's head-quarters Sunday morning, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ witnesses said. The agents had warrants to search for guns and explosives and to arrest Howell, said Les Stanford of the ATF in Washington. [...] Witnesses said the law officers stormed the compound's main home, throwing concussion grenades and screaming "Come out," while three ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ National Guard helicopters approached. For a moment, there was no response. Then the shooting began. I think "storming the sect's head-quaters" and "throwing concussion grenades" qualifies as a no-knock (or perhaps an illegal assault). > he was not just another guy minding his own business.

Rob, I am not intimate with Jewish theology, but I understand that you are a Messianic Jew. Correct me if I am wrong, but it appears that the views of Messianic Jews on metaphysics is different to that of the majority of Jews. While Jewish theology overall is quite distinct from the Christianic god views, I have heard that it is possible for Jews to attribute evil to their god, an no-no for Christians, the Bible is still seen as effect of the interaction of some god with man.

Either there is some connection between the text, the fact that it exists, and your interpretation of it, or it is purely arbitrary.. Further, the question is why is has one to carry the burden of Biblical texts when one could simply write other books that convey the message better. You might answer that one can't becuase some peculiar Biblical information might be lost, but that holds true of every other book, and the question remains why has the Bible still a special place? Can't it be replaced somehow? Is it ok to bargain the dangerous content of the Bible against some other message that is included as well? (Deletion) >|> Do you see the danger in doing so?

And the argument you have given is a fallacy, while it may not be important in the context you have given to find out if god is corporeal or not, it can be crucial in other questions. Religious believers resolve contradictions with that they choose one of the possibilities given in an arbitrary way, and have the advantage of being able to attribute their decision to some god. One cannot resolve questions by the statement do what is good when what is good depends on the question. Benedikt

If a player does well at AA and then does not improve at AAA, isn't that a sign that maybe he doesn't belong in the bigs? Now, Keith Mitchell. As I recall (no stat books handy - surprise!) he jumped from AA to Atlanta in 1991. He did so well that he was returned to the minors, where he didn't do very well at all. Now his career is in jeopardy. So how does he fit in with your point. Good MLE's in AA. Moved him right to the big club. Now he's one step away from being traded or moved out of baseball.

It's amazing how hard it is to get baseball teams to understand how to properly market their teams and treat their customers. No other business could ever get away with the 19th century attitudes that most current owners display in running their clubs. I guess the owners look at baseball's high growth rate and ask why it's necessary to bring 20th century business practices into the game, but they don't realize how much more growth the game is capable of and how much they pay in terms of long-term popularity by not doing better by the game and its fans.

Anyone have any ideas ?? I expect the limiting factor will be your server machine, not the network itself. To give you a real-world example, here at Quarterdeck we have roughly 100 people using DVX to talk to a bunch of unix boxes, novell file servers, and each other. It's not _too_ much of a load on our Ethernet (with maybe 4 concentrators, so you have 20-30 people on each segment). If you had a badly loaded net, or the apps you wanted to run were very network intensive, you could run into some slowdowns. But the biggest problem would be the machine itself. Say you have a 486 33 with plenty of ram and a fast hard disk and network card. If you have 10 people running programs off it, you're going to see some slowdowns because you're now on (effectively) a 3.3 MHz 486. Of course, DVX will attempt to see if tasks are idle and make sure they give up their time slice, but if you have 10 working programs running, you'll know it. Having said that, if you can tweak the programs being run (by adding in calls to give up time slices when idle and that sort of thing), you could probably run 15-20 people on a given machine before you started seeing slowdowns again (this time from network bandwidth). It all really depends on what the programs are doing (ie. you're going to see a slowdown from X-bandwidth a lot sooner if your apps are all doing network things also...) -- Quarterdeck Office Systems - Internet Support - Tom Bortels Pricing/Ordering : info@qdeck.com | Tech Questions : support@qdeck.com BBS: (310) 314-3227 * FAX: (310) 314-3217 * Compuserve: GO QUARTERDECK Q/Fax: (310) 314-3214 from touch-tone phone for Technotes On Demand!

II., p. 188. "The atrocities and massacres which have been committed for a long time against the Muslim population within the Armenian Republic have been confirmed with very accurate information, and the observations made by Rawlinson, the British representative in Erzurum, have confirmed that these atrocities are being committed by the Armenians. The United States delegation of General Harbord has seen the thousands of refugees who came to take refuge with Kazim Karabekir's soldiers, hungry and miserable, their children and wives, their properties destroyed, and the delegation was a witness to the cruelties. Many Muslim villages have been destroyed by the soldiers of Armenian troops armed with cannons and machine guns before the eyes of Karabekir's troops and the people. When it was hoped that this operation would end, unfortunately since the beginning of February the cruelties inflicted on the Muslim population of the region of Shuraghel, Akpazar, Zarshad, and Childir have increased. According to documented information, 28 Muslim villages have been destroyed in the aforementioned region, more than 2,000 people have been slaughtered, many possessions and livestock have been seized, young Muslim women have been taken to Kars and Gumru, thousands of women and children who were able to flee their villages were beaten, raped and massacred in the mountains, and this aggression against the properties, lives, chastity and honour of the Muslims continued. It was the responsibility of the Armenian Government that the cruelties and massacres be stopped in order to alleviate the tensions of Muslim public opinion due to the atrocities committed by the Armenians, that the possessions taken from the Muslims be returned and that indemnities be paid, that the properties, lives, and honour of the Muslims be protected."

In fact, it is the fact that hospitals frequently compete for physicians rather than for patients that (in part) complicates and undermines a simplistic free-market analysis of the market for medical care. >Hospitals tend to lose money on all sorts of high-tech, high-price >machinery. They manage to make it up on other charges. Once again, there is no evidence that this is true in regard to kidney dialysis. Although price controls have promoted an expansion of services to a much greater volume of patients, RD is still a profitable service. Otherwise, one would expect to see evidence of rationing rather than the vast expansion that has occurred. > >> Remember, the notion that you can lose a little on each treatment but >> make it up in volume is not good economics even in a free market. :) > >Then how do you explain why grocery stores routinely offer an >array of products at prices below cost? Are not grocery stores >embedded in a relatively free market? Can you spell "loss leader?" I knew you could. Grocery stores do not attempt to make up the loss on an individual product by selling more of it. In fact, your argument above is that kidney dialysis is a loss leader for other medical treatments where lost revenue can be regained. But the evidence does not support this contention. Rather, it appears that price controls have disciplined the market by forcing an expansion of service and development of improved lower-cost technology to provide comparable benefits. Providers continue to profit from RD, they simply make less on each treatment than they would have if the price had risen at the rate that uncontrolled treatments have. There is no question that had price controls forced the price of RD substantially below its actual cost that some or all of the doomsday predictions of free-market advocates would have been seen -- restriction of service, lagging technological development, etc. Likewise, it appears that in the VA and armed forces medical care systems, where providers are government agencies, some of these negative impacts may occur. (RD patients in the VA system in Spokane, for example, must travel to Seattle, 300 miles away, for treatment.) The bottom line, however, is that this is an example of government intervention (of a rather extreme sort) that appears to have had beneficial results for both providers and consumers. Claims that "government bureaucracy" inevitably leads to undesirable outcomes in the marketplace should take such such cases into account. jsh > >=Mark -- Steve Hendricks | DOMAIN: steveh@thor.ISC-BR.COM "One thing about data, it sure does cut| UUCP: ...!uunet!isc-br!thor!steveh the bulls**t." - R.

Of course the chances of Ok It is for a game that is 3d and you have listed the characteristics that you are looking for. I think you may have left out a few important parameters. The polygons are all convex. They have less than N sides. (you are drawing meshes walls doors etc.) I believe that the algorithms you can get that will only draw convex polygons can be much more efficient than those that can draw concave / self intersecting polygons. This efficiency can largely be attributed to the fact that simple convex polygons only have a left and a right edge on each scan line. Complex (figure 8 type polygons) can be a bit trickier. The less than N sides specification especially if it is a very small number like 3 or 4 allow othe optimisations to be made. Thus for a high speed game application I think you are looking for code that exploits and is hence limited to drawing simple convex polygons. >finding something like that are pretty remote, so I guess I'd need the source >with it.

I've been hunting high and low It may have been that they were very general purpose algorithms. If you limit yourself to 3 or four sided simple convex polygons I think you might be suprised how fast a c algorithm with a asm block move to fill each scan line might actually be. >for a polyn function in ASM, and I can't find one anywhere that I can use. >I've found one or two polyn functions, but my ASM is pretty bad, so I won't >even try to rewrite them. :) > //Lucas.

Amplifying on Jeff Goss's answer, the absorbed water will rust your brakelines and master cylinder and calipers and you could suddenly lose all your brake fluid.
