CHAPTER 3. The Spouter-Inn.
Entering that gable-ended Spouter-Inn, you found yourself in a wide, low, straggling entry with old-fashioned wainscots, reminding one of the bulwarks of some condemned old craft. On one side hung a very large oilpainting so thoroughly besmoked, and every way defaced, that in the unequal crosslights by which you viewed it, it was only by diligent study and a series of systematic visits to it, and careful inquiry of the neighbors, that you could any way arrive at an understanding of its purpose. Such unaccountable masses of shades and shadows, that at first you almost thought some ambitious young artist, in the time of the New England hags, had endeavored to delineate chaos bewitched. But by dint of much and earnest contemplation, and oft repeated ponderings, and especially by throwing open the little window towards the back of the entry, you at last come to the conclusion that such an idea, however wild, might not be altogether unwarranted.
But what most puzzled and confounded you was a long, limber, portentous, black mass of something hovering in the centre of the picture over three blue, dim, perpendicular lines floating in a nameless yeast.  Yet was there a sort of indefinite, half-attained, unimaginable sublimity about it that fairly froze you to it, till you involuntarily took an oath with yourself to find out what that marvellous painting meant. Ever and anon a bright, but, alas, deceptive idea would dart you through.It's the Black Sea in a midnight gale.It's the unnatural combat of the four primal elements.It's a blasted heath.It's a Hyperborean winter scene.It's the breaking-up of the icebound stream of Time. But at last all these fancies yielded to that one portentous something in the picture's midst. That once found out, and all the rest were plain. But stop; does it not bear a faint resemblance to a gigantic fish? even the great leviathan himself?
In fact, the artist's design seemed this: a final theory of my own, partly based upon the aggregated opinions of many aged persons with whom I conversed upon the subject. The picture represents a Cape-Horner in a great hurricane; the half-foundered ship weltering there with its three dismantled masts alone visible; and an exasperated whale, purposing to spring clean over the craft, is in the enormous act of impaling himself upon the three mast-heads.
The opposite wall of this entry was hung all over with a heathenish array of monstrous clubs and spears. Some were thickly set with glittering teeth resembling ivory saws; others were tufted with knots of human hair; and one was sickle-shaped, with a vast handle sweeping round like the segment made in the new-mown grass by a long-armed mower. You shuddered as you gazed, and wondered what monstrous cannibal and savage could ever have gone a death-harvesting with such a hacking, horrifying implement. Mixed with these were rusty old whaling lances and harpoons all broken and deformed. Some were storied weapons. With this once long lance, now wildly elbowed, fifty years ago did Nathan Swain kill fifteen whales between a sunrise and a sunset.  The original iron entered nigh the tail, and, like a restless needle sojourning in the body of a man, travelled full forty feet, and at last was found imbedded in the hump.
Crossing this dusky entry, and on through yon low-arched waycut through what in old times must have been a great central chimney with fireplaces all roundyou enter the public room. A still duskier place is this, with such low ponderous beams above, and such old wrinkled planks beneath, that you would almost fancy you trod some old craft's cockpits, especially of such a howling night, when this corner-anchored old ark rocked so furiously. On one side stood a long, low, shelf-like table covered with cracked glass cases, filled with dusty rarities gathered from this wide world's remotest nooks. Projecting from the further angle of the room stands a dark-looking denthe bara rude attempt at a right whale's head. Be that how it may, there stands the vast arched bone of the whale's jaw, so wide, a coach might almost drive beneath it. Within are shabby shelves, ranged round with old decanters, bottles, flasks; and in those jaws of swift destruction, like another cursed Jonah (by which name indeed they called him), bustles a little withered old man, who, for their money, dearly sells the sailors deliriums and death.
Abominable are the tumblers into which he pours his poison. Though true cylinders withoutwithin, the villanous green goggling glasses deceitfully tapered downwards to a cheating bottom. Parallel meridians rudely pecked into the glass, surround these footpads' goblets. Fill to this mark, and your charge is but a penny; to this a penny more; and so on to the full glassthe Cape Horn measure, which you may gulp down for a shilling.
Upon entering the place I found a number of young seamen gathered about a table, examining by a dim light divers specimens of skrimshander. I sought the landlord, and telling him I desired to be accommodated with a room, received for answer that his house was fullnot a bed unoccupied. "But avast," he added, tapping his forehead, "you haint no objections to sharing a harpooneer's blanket, have ye? I s'pose you are goin' a-whalin', so you'd better get used to that sort of thing."
I told him that I never liked to sleep two in a bed; that if I should ever do so, it would depend upon who the harpooneer might be, and that if he (the landlord) really had no other place for me, and the harpooneer was not decidedly objectionable, why rather than wander further about a strange town on so bitter a night, I would put up with the half of any decent man's blanket.
"I thought so. All right; take a seat. Supper?you want supper? Supper'll be ready directly."
I sat down on an old wooden settle, carved all over like a bench on the Battery. At one end a ruminating tar was still further adorning it with his jack-knife, stooping over and diligently working away at the space between his legs. He was trying his hand at a ship under full sail, but he didn't make much headway, I thought.
At last some four or five of us were summoned to our meal in an adjoining room. It was cold as Icelandno fire at allthe landlord said he couldn't afford it. Nothing but two dismal tallow candles, each in a winding sheet. We were fain to button up our monkey jackets, and hold to our lips cups of scalding tea with our half frozen fingers. But the fare was of the most substantial kindnot only meat and potatoes, but dumplings; good heavens! dumplings for supper! One young fellow in a green box coat, addressed himself to these dumplings in a most direful manner.
"My boy," said the landlord, "you'll have the nightmare to a dead sartainty."
"Landlord," I whispered, "that aint the harpooneer is it?"
"Oh, no," said he, looking a sort of diabolically funny, "the harpooneer is a dark complexioned chap.
"The devil he does," says I. "Where is that harpooneer? Is he here?"
"He'll be here afore long," was the answer.
I could not help it, but I began to feel suspicious of this "dark complexioned" harpooneer. At any rate, I made up my mind that if it so turned out that we should sleep together, he must undress and get into bed before I did.
Supper over, the company went back to the bar-room, when, knowing not what else to do with myself, I resolved to spend the rest of the evening as a looker on.
Presently a rioting noise was heard without. Starting up, the landlord cried, "That's the Grampus's crew. I seed her reported in the offing this morning; a three years' voyage, and a full ship. Hurrah, boys; now we'll have the latest news from the Feegees."
A tramping of sea boots was heard in the entry; the door was flung open, and in rolled a wild set of mariners enough. Enveloped in their shaggy watch coats, and with their heads muffled in woollen comforters, all bedarned and ragged, and their beards stiff with icicles, they seemed an eruption of bears from Labrador. They had just landed from their boat, and this was the first house they entered. No wonder, then, that they made a straight wake for the whale's mouththe barwhen the wrinkled little old Jonah, there officiating, soon poured them out brimmers all round. One complained of a bad cold in his head, upon which Jonah mixed him a pitch-like potion of gin and molasses, which he swore was a sovereign cure for all colds and catarrhs whatsoever, never mind of how long standing, or whether caught off the coast of Labrador, or on the weather side of an ice-island.
The liquor soon mounted into their heads, as it generally does even with the arrantest topers newly landed from sea, and they began capering about most obstreperously.
I observed, however, that one of them held somewhat aloof, and though he seemed desirous not to spoil the hilarity of his shipmates by his own sober face, yet upon the whole he refrained from making as much noise as the rest. This man interested me at once; and since the sea-gods had ordained that he should soon become my shipmate (though but a sleeping-partner one, so far as this narrative is concerned), I will here venture upon a little description of him. He stood full six feet in height, with noble shoulders, and a chest like a coffer-dam. I have seldom seen such brawn in a man. His face was deeply brown and burnt, making his white teeth dazzling by the contrast; while in the deep shadows of his eyes floated some reminiscences that did not seem to give him much joy. His voice at once announced that he was a Southerner, and from his fine stature, I thought he must be one of those tall mountaineers from the Alleghanian Ridge in Virginia. When the revelry of his companions had mounted to its height, this man slipped away unobserved, and I saw no more of him till he became my comrade on the sea. In a few minutes, however, he was missed by his shipmates, and being, it seems, for some reason a huge favourite with them, they raised a cry of "Bulkington! Bulkington! where's Bulkington?" and darted out of the house in pursuit of him.
It was now about nine o'clock, and the room seeming almost supernaturally quiet after these orgies, I began to congratulate myself upon a little plan that had occurred to me just previous to the entrance of the seamen.
No man prefers to sleep two in a bed. In fact, you would a good deal rather not sleep with your own brother. I don't know how it is, but people like to be private when they are sleeping. And when it comes to sleeping with an unknown stranger, in a strange inn, in a strange town, and that stranger a harpooneer, then your objections indefinitely multiply. Nor was there any earthly reason why I as a sailor should sleep two in a bed, more than anybody else; for sailors no more sleep two in a bed at sea, than bachelor Kings do ashore. To be sure they all sleep together in one apartment, but you have your own hammock, and cover yourself with your own blanket, and sleep in your own skin.
The more I pondered over this harpooneer, the more I abominated the thought of sleeping with him. It was fair to presume that being a harpooneer, his linen or woollen, as the case might be, would not be of the tidiest, certainly none of the finest. I began to twitch all over. Besides, it was getting late, and my decent harpooneer ought to be home and going bedwards. Suppose now, he should tumble in upon me at midnighthow could I tell from what vile hole he had been coming?
"Landlord! I've changed my mind about that harpooneer.I shan't sleep with him. I'll try the bench here."
"Just as you please; I'm sorry I cant spare ye a tablecloth for a mattress, and it's a plaguy rough board here"feeling of the knots and notches. "But wait a bit, Skrimshander; I've got a carpenter's plane there in the barwait, I say, and I'll make ye snug enough." So saying he procured the plane; and with his old silk handkerchief first dusting the bench, vigorously set to planing away at my bed, the while grinning like an ape. The shavings flew right and left; till at last the plane-iron came bump against an indestructible knot. The landlord was near spraining his wrist, and I told him for heaven's sake to quitthe bed was soft enough to suit me, and I did not know how all the planing in the world could make eider down of a pine plank. So gathering up the shavings with another grin, and throwing them into the great stove in the middle of the room, he went about his business, and left me in a brown study.
I now took the measure of the bench, and found that it was a foot too short; but that could be mended with a chair. But it was a foot too narrow, and the other bench in the room was about four inches higher than the planed oneso there was no yoking them. I then placed the first bench lengthwise along the only clear space against the wall, leaving a little interval between, for my back to settle down in. But I soon found that there came such a draught of cold air over me from under the sill of the window, that this plan would never do at all, especially as another current from the rickety door met the one from the window, and both together formed a series of small whirlwinds in the immediate vicinity of the spot where I had thought to spend the night.
The devil fetch that harpooneer, thought I, but stop, couldn't I steal a march on himbolt his door inside, and jump into his bed, not to be wakened by the most violent knockings? It seemed no bad idea; but upon second thoughts I dismissed it. For who could tell but what the next morning, so soon as I popped out of the room, the harpooneer might be standing in the entry, all ready to knock me down!
Still, looking round me again, and seeing no possible chance of spending a sufferable night unless in some other person's bed, I began to think that after all I might be cherishing unwarrantable prejudices against this unknown harpooneer. Thinks I, I'll wait awhile; he must be dropping in before long. I'll have a good look at him then, and perhaps we may become jolly good bedfellows after allthere's no telling.
But though the other boarders kept coming in by ones, twos, and threes, and going to bed, yet no sign of my harpooneer.
"Landlord!" said I, "what sort of a chap is hedoes he always keep such late hours?" It was now hard upon twelve o'clock.
The landlord chuckled again with his lean chuckle, and seemed to be mightily tickled at something beyond my comprehension. "No," he answered, "generally he's an early birdairley to bed and airley to riseyes, he's the bird what catches the worm. But to-night he went out a peddling, you see, and I don't see what on airth keeps him so late, unless, may be, he can't sell his head."
"Can't sell his head?What sort of a bamboozingly story is this you are telling me?" getting into a towering rage. "Do you pretend to say, landlord, that this harpooneer is actually engaged this blessed Saturday night, or rather Sunday morning, in peddling his head around this town?"
"That's precisely it," said the landlord, "and I told him he couldn't sell it here, the market's overstocked."
"With what?" shouted I.
"With heads to be sure; ain't there too many heads in the world?"
"I tell you what it is, landlord," said I quite calmly, "you'd better stop spinning that yarn to meI'm not green."

"I'll break it for him," said I, now flying into a passion again at this unaccountable farrago of the landlord's.
"It's broke a'ready," said he.
"Broke," said I"broke, do you mean?"
"Sartain, and that's the very reason he can't sell it, I guess."
"Landlord," said I, going up to him as cool as Mt. Hecla in a snow-storm"landlord, stop whittling. You and I must understand one another, and that too without delay.  And about this harpooneer, whom I have not yet seen, you persist in telling me the most mystifying and exasperating stories tending to beget in me an uncomfortable feeling towards the man whom you design for my bedfellowa sort of connexion, landlord, which is an intimate and confidential one in the highest degree. I now demand of you to speak out and tell me who and what this harpooneer is, and whether I shall be in all respects safe to spend the night with him. And in the first place, you will be so good as to unsay that story about selling his head, which if true I take to be good evidence that this harpooneer is stark mad, and I've no idea of sleeping with a madman; and you, sir, you I mean, landlord, you, sir, by trying to induce me to do so knowingly, would thereby render yourself liable to a criminal prosecution."
"Wall," said the landlord, fetching a long breath, "that's a purty long sarmon for a chap that rips a little now and then. But be easy, be easy, this here harpooneer I have been tellin' you of has just arrived from the south seas, where he bought up a lot of 'balmed New Zealand heads (great curios, you know), and he's sold all on 'em but one, and that one he's trying to sell to-night, cause to-morrow's Sunday, and it would not do to be sellin' human heads about the streets when folks is goin' to churches. He wanted to, last Sunday, but I stopped him just as he was goin' out of the door with four heads strung on a string, for all the airth like a string of inions."
This account cleared up the otherwise unaccountable mystery, and showed that the landlord, after all, had had no idea of fooling mebut at the same time what could I think of a harpooneer who stayed out of a Saturday night clean into the holy Sabbath, engaged in such a cannibal business as selling the heads of dead idolators?
"Depend upon it, landlord, that harpooneer is a dangerous man."
"He pays reg'lar," was the rejoinder. "But come, it's getting dreadful late, you had better be turning flukesit's a nice bed; Sal and me slept in that ere bed the night we were spliced. There's plenty of room for two to kick about in that bed; it's an almighty big bed that. Why, afore we give it up, Sal used to put our Sam and little Johnny in the foot of it. But I got a dreaming and sprawling about one night, and somehow, Sam got pitched on the floor, and came near breaking his arm. Arter that, Sal said it wouldn't do. Come along here, I'll give ye a glim in a jiffy;" and so saying he lighted a candle and held it towards me, offering to lead the way. But I stood irresolute; when looking at a clock in the corner, he exclaimed "I vum it's Sundayyou won't see that harpooneer to-night; he's come to anchor somewherecome along then; do come; won't ye come?"
I considered the matter a moment, and then up stairs we went, and I was ushered into a small room, cold as a clam, and furnished, sure enough, with a prodigious bed, almost big enough indeed for any four harpooneers to sleep abreast.
"There," said the landlord, placing the candle on a crazy old sea chest that did double duty as a wash-stand and centre table; "there, make yourself comfortable now, and good night to ye." I turned round from eyeing the bed, but he had disappeared.
Folding back the counterpane, I stooped over the bed. Though none of the most elegant, it yet stood the scrutiny tolerably well. I then glanced round the room; and besides the bedstead and centre table, could see no other furniture belonging to the place, but a rude shelf, the four walls, and a papered fireboard representing a man striking a whale. Of things not properly belonging to the room, there was a hammock lashed up, and thrown upon the floor in one corner; also a large seaman's bag, containing the harpooneer's wardrobe, no doubt in lieu of a land trunk. Likewise, there was a parcel of outlandish bone fish hooks on the shelf over the fire-place, and a tall harpoon standing at the head of the bed.
But what is this on the chest? I took it up, and held it close to the light, and felt it, and smelt it, and tried every way possible to arrive at some satisfactory conclusion concerning it.  There was a hole or slit in the middle of this mat, as you see the same in South American ponchos. But could it be possible that any sober harpooneer would get into a door mat, and parade the streets of any Christian town in that sort of guise? I put it on, to try it, and it weighed me down like a hamper, being uncommonly shaggy and thick, and I thought a little damp, as though this mysterious harpooneer had been wearing it of a rainy day. I went up in it to a bit of glass stuck against the wall, and I never saw such a sight in my life.
I sat down on the side of the bed, and commenced thinking about this head-peddling harpooneer, and his door mat. After thinking some time on the bed-side, I got up and took off my monkey jacket, and then stood in the middle of the room thinking. I then took off my coat, and thought a little more in my shirt sleeves. But beginning to feel very cold now, half undressed as I was, and remembering what the landlord said about the harpooneer's not coming home at all that night, it being so very late, I made no more ado, but jumped out of my pantaloons and boots, and then blowing out the light tumbled into bed, and commended myself to the care of heaven.
Whether that mattress was stuffed with corn-cobs or broken crockery, there is no telling, but I rolled about a good deal, and could not sleep for a long time. At last I slid off into a light doze, and had pretty nearly made a good offing towards the land of Nod, when I heard a heavy footfall in the passage, and saw a glimmer of light come into the room from under the door.
Lord save me, thinks I, that must be the harpooneer, the infernal head-peddler. But I lay perfectly still, and resolved not to say a word till spoken to. Holding a light in one hand, and that identical New Zealand head in the other, the stranger entered the room, and without looking towards the bed, placed his candle a good way off from me on the floor in one corner, and then began working away at the knotted cords of the large bag I before spoke of as being in the room. I was all eagerness to see his face, but he kept it averted for some time while employed in unlacing the bag's mouth. This accomplished, however, he turned roundwhen, good heavens! what a sight! Such a face! It was of a dark, purplish, yellow colour, here and there stuck over with large blackish looking squares. Yes, it's just as I thought, he's a terrible bedfellow; he's been in a fight, got dreadfully cut, and here he is, just from the surgeon. But at that moment he chanced to turn his face so towards the light, that I plainly saw they could not be sticking-plasters at all, those black squares on his cheeks. They were stains of some sort or other. At first I knew not what to make of this; but soon an inkling of the truth occurred to me. I remembered a story of a white mana whaleman toowho, falling among the cannibals, had been tattooed by them. I concluded that this harpooneer, in the course of his distant voyages, must have met with a similar adventure. And what is it, thought I, after all! It's only his outside; a man can be honest in any sort of skin. But then, what to make of his unearthly complexion, that part of it, I mean, lying round about, and completely independent of the squares of tattooing. To be sure, it might be nothing but a good coat of tropical tanning; but I never heard of a hot sun's tanning a white man into a purplish yellow one. However, I had never been in the South Seas; and perhaps the sun there produced these extraordinary effects upon the skin. Now, while all these ideas were passing through me like lightning, this harpooneer never noticed me at all. But, after some difficulty having opened his bag, he commenced fumbling in it, and presently pulled out a sort of tomahawk, and a seal-skin wallet with the hair on. Placing these on the old chest in the middle of the room, he then took the New Zealand heada ghastly thing enoughand crammed it down into the bag. He now took off his hata new beaver hatwhen I came nigh singing out with fresh surprise. There was no hair on his headnone to speak of at leastnothing but a small scalp-knot twisted up on his forehead. His bald purplish head now looked for all the world like a mildewed skull. Had not the stranger stood between me and the door, I would have bolted out of it quicker than ever I bolted a dinner.
Even as it was, I thought something of slipping out of the window, but it was the second floor back. I am no coward, but what to make of this head-peddling purple rascal altogether passed my comprehension. Ignorance is the parent of fear, and being completely nonplussed and confounded about the stranger, I confess I was now as much afraid of him as if it was the devil himself who had thus broken into my room at the dead of night. In fact, I was so afraid of him that I was not game enough just then to address him, and demand a satisfactory answer concerning what seemed inexplicable in him.
Meanwhile, he continued the business of undressing, and at last showed his chest and arms. As I live, these covered parts of him were checkered with the same squares as his face; his back, too, was all over the same dark squares; he seemed to have been in a Thirty Years' War, and just escaped from it with a sticking-plaster shirt. Still more, his very legs were marked, as if a parcel of dark green frogs were running up the trunks of young palms. It was now quite plain that he must be some abominable savage or other shipped aboard of a whaleman in the South Seas, and so landed in this Christian country. I quaked to think of it. A peddler of heads tooperhaps the heads of his own brothers. He might take a fancy to mineheavens! look at that tomahawk!
But there was no time for shuddering, for now the savage went about something that completely fascinated my attention, and convinced me that he must indeed be a heathen. Going to his heavy grego, or wrapall, or dreadnaught, which he had previously hung on a chair, he fumbled in the pockets, and produced at length a curious little deformed image with a hunch on its back, and exactly the colour of a three days' old Congo baby. Remembering the embalmed head, at first I almost thought that this black manikin was a real baby preserved in some similar manner. But seeing that it was not at all limber, and that it glistened a good deal like polished ebony, I concluded that it must be nothing but a wooden idol, which indeed it proved to be. For now the savage goes up to the empty fire-place, and removing the papered fire-board, sets up this little hunch-backed image, like a tenpin, between the andirons. The chimney jambs and all the bricks inside were very sooty, so that I thought this fire-place made a very appropriate little shrine or chapel for his Congo idol.
I now screwed my eyes hard towards the half hidden image, feeling but ill at ease meantimeto see what was next to follow. First he takes about a double handful of shavings out of his grego pocket, and places them carefully before the idol; then laying a bit of ship biscuit on top and applying the flame from the lamp, he kindled the shavings into a sacrificial blaze. Presently, after many hasty snatches into the fire, and still hastier withdrawals of his fingers (whereby he seemed to be scorching them badly), he at last succeeded in drawing out the biscuit; then blowing off the heat and ashes a little, he made a polite offer of it to the little negro. But the little devil did not seem to fancy such dry sort of fare at all; he never moved his lips. All these strange antics were accompanied by still stranger guttural noises from the devotee, who seemed to be praying in a sing-song or else singing some pagan psalmody or other, during which his face twitched about in the most unnatural manner.
All these queer proceedings increased my uncomfortableness, and seeing him now exhibiting strong symptoms of concluding his business operations, and jumping into bed with me, I thought it was high time, now or never, before the light was put out, to break the spell in which I had so long been bound.
But the interval I spent in deliberating what to say, was a fatal one. Taking up his tomahawk from the table, he examined the head of it for an instant, and then holding it to the light, with his mouth at the handle, he puffed out great clouds of tobacco smoke. The next moment the light was extinguished, and this wild cannibal, tomahawk between his teeth, sprang into bed with me. I sang out, I could not help it now; and giving a sudden grunt of astonishment he began feeling me.
Stammering out something, I knew not what, I rolled away from him against the wall, and then conjured him, whoever or whatever he might be, to keep quiet, and let me get up and light the lamp again. But his guttural responses satisfied me at once that he but ill comprehended my meaning.
"Who-e debel you?"he at last said"you no speak-e, dam-me, I kill-e." And so saying the lighted tomahawk began flourishing about me in the dark.
"Landlord, for God's sake, Peter Coffin!" shouted I. "Landlord! Watch! Coffin! Angels! save me!"
"Speak-e! tell-ee me who-ee be, or dam-me, I kill-e!" again growled the cannibal, while his horrid flourishings of the tomahawk scattered the hot tobacco ashes about me till I thought my linen would get on fire. But thank heaven, at that moment the landlord came into the room light in hand, and leaping from the bed I ran up to him.
"Don't be afraid now," said he, grinning again, "Queequeg here wouldn't harm a hair of your head."
"Stop your grinning," shouted I, "and why didn't you tell me that that infernal harpooneer was a cannibal?"
"I thought ye know'd it;didn't I tell ye, he was a peddlin' heads around town?but turn flukes again and go to sleep. Queequeg, look hereyou sabbee me, I sabbeeyou this man sleepe youyou sabbee?"
"Me sabbee plenty"grunted Queequeg, puffing away at his pipe and sitting up in bed.
"You gettee in," he added, motioning to me with his tomahawk, and throwing the clothes to one side. He really did this in not only a civil but a really kind and charitable way. I stood looking at him a moment. For all his tattooings he was on the whole a clean, comely looking cannibal. What's all this fuss I have been making about, thought I to myselfthe man's a human being just as I am: he has just as much reason to fear me, as I have to be afraid of him. Better sleep with a sober cannibal than a drunken Christian.
"Landlord," said I, "tell him to stash his tomahawk there, or pipe, or whatever you call it; tell him to stop smoking, in short, and I will turn in with him. But I don't fancy having a man smoking in bed with me. It's dangerous. Besides, I ain't insured."
This being told to Queequeg, he at once complied, and again politely motioned me to get into bedrolling over to one side as much as to say"I won't touch a leg of ye."
"Good night, landlord," said I, "you may go."
I turned in, and never slept better in my life.

| HOST_STATE_WaitForDevice | This state indicates that the stack is waiting for an interval to elapse before continuing with the next step of the device enumeration process. |
| HOST_STATE_Unattached | This state indicates that the host state machine is waiting for a device to be attached so that it can start the enumeration process. |
| HOST_STATE_Powered | This state indicates that a device has been attached, and the library's internals are being configured to begin the enumeration process. |
| HOST_STATE_Powered_WaitForDeviceSettle | This state indicates that the stack is waiting for the initial settling period to elapse before beginning the enumeration process. |
| HOST_STATE_Powered_WaitForConnect | This state indicates that the stack is waiting for a connection event from the USB controller to indicate a valid USB device has been attached to the bus and is ready to be enumerated. |
| HOST_STATE_Powered_DoReset | This state indicates that a valid USB device has been attached, and that it will now be reset to ensure it is ready for enumeration. |
| HOST_STATE_Powered_ConfigPipe | This state indicates that the attached device is currently powered and reset, and that the control pipe is now being configured by the stack. |
| HOST_STATE_Default | This state indicates that the stack is currently retrieving the control endpoint's size from the device, so that the control pipe can be altered to match. |
| HOST_STATE_Default_PostReset | This state indicates that the control pipe is being reconfigured to match the retrieved control endpoint size from the device, and the device's USB bus address is being set. |
| HOST_STATE_Default_PostAddressSet | This state indicates that the device's address has now been set, and the stack is has now completed the device enumeration process. This state causes the stack to change the current USB device address to that set for the connected device, before progressing to the HOST_STATE_Addressed state ready for use in the user application. |
| HOST_STATE_Addressed | Indicates that the device has been enumerated and addressed, and is now waiting for the user application to configure the device ready for use. |
| HOST_STATE_Configured | Indicates that the device has been configured into a valid device configuration, ready for general use by the user application. |
| uint8_t USB_Host_ConfigurationNumber |
Indicates the currently set configuration number of the attached device. This indicates the currently selected configuration value if one has been set sucessfully, or 0 if no configuration has been selected.
To set a device configuration, call the USB_Host_SetDeviceConfiguration() function.
| volatile uint8_t USB_HostState |
Indicates the current host state machine state. When in host mode, this indicates the state via one of the values of the USB_Host_States_t enum values.
This value should not be altered by the user application as it is handled automatically by the library.
To reduce program size and speed up checks of this global on the AVR8 architecture, it can be placed into one of the AVR's GPIOR
hardware registers instead of RAM by defining the HOST_STATE_AS_GPIOR
token to a value between 0 and 2 in the project makefile and passing it to the compiler via the -D switch. When defined, the corresponding GPIOR register should not be used in the user application except implicitly via the library APIs.


A Psalm of thanksgiving.
1 Shout for joy to Yahweh, all you lands!
2 Serve Yahweh with gladness.
Come before his presence with singing.
3 Know that Yahweh, he is God.
It is he who has made us, and we are his.
We are his people, and the sheep of his pasture.
4 Enter into his gates with thanksgiving,
and into his courts with praise.
Give thanks to him, and bless his name.
5 For Yahweh is good.
His loving kindness endures forever,
his faithfulness to all generations.

#include <sys/uio.h> ssize_t process_vm_readv(pid_t pid, const struct iovec *local_iov, unsigned long liovcnt, const struct iovec *remote_iov, unsigned long riovcnt, unsigned long flags); ssize_t process_vm_writev(pid_t pid, const struct iovec *local_iov, unsigned long liovcnt, const struct iovec *remote_iov, unsigned long riovcnt, unsigned long flags);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
process_vm_readv(), process_vm_write():
The process_vm_readv() system call transfers data from the remote process to the local process. The data to be transferred is identified by remote_iov and riovcnt: remote_iov is a pointer to an array describing address ranges in the process pid, and riovcnt specifies the number of elements in remote_iov. The data is transferred to the locations specified by local_iov and liovcnt: local_iov is a pointer to an array describing address ranges in the calling process, and liovcnt specifies the number of elements in local_iov.
The process_vm_writev() system call is the converse of process_vm_readv()---it transfers data from the local process to the remote process. Other than the direction of the transfer, the arguments liovcnt, local_iov, riovcnt, and remote_iov have the same meaning as for process_vm_readv().
The local_iov and remote_iov arguments point to an array of iovec structures, defined in <sys/uio.h> as:
struct iovec { void *iov_base; /* Starting address */ size_t iov_len; /* Number of bytes to transfer */ };
Buffers are processed in array order. This means that process_vm_readv() completely fills local_iov[0] before proceeding to local_iov[1], and so on. Likewise, remote_iov[0] is completely read before proceeding to remote_iov[1], and so on.
Similarly, process_vm_writev() writes out the entire contents of local_iov[0] before proceeding to local_iov[1], and it completely fills remote_iov[0] before proceeding to remote_iov[1].
The lengths of remote_iov[i].iov_len and local_iov[i].iov_len do not have to be the same. Thus, it is possible to split a single local buffer into multiple remote buffers, or vice versa.
The flags argument is currently unused and must be set to 0.
The values specified in the liovcnt and riovcnt arguments must be less than or equal to IOV_MAX (defined in <limits.h> or accessible via the call sysconf(_SC_IOV_MAX)).
The count arguments and local_iov are checked before doing any transfers. If the counts are too big, or local_iov is invalid, or the addresses refer to regions that are inaccessible to the local process, none of the vectors will be processed and an error will be returned immediately.
Note, however, that these system calls do not check the memory regions in the remote process until just before doing the read/write. Consequently, a partial read/write (see RETURN VALUE) may result if one of the remote_iov elements points to an invalid memory region in the remote process. No further reads/writes will be attempted beyond that point. Keep this in mind when attempting to read data of unknown length (such as C strings that are null-terminated) from a remote process, by avoiding spanning memory pages (typically 4KiB) in a single remote iovec element. (Instead, split the remote read into two remote_iov elements and have them merge back into a single write local_iov entry. The first read entry goes up to the page boundary, while the second starts on the next page boundary.)
In order to read from or write to another process, either the caller must have the capability CAP_SYS_PTRACE, or the real user ID, effective user ID, and saved set-user-ID of the remote process must match the real user ID of the caller and the real group ID, effective group ID, and saved set-group-ID of the remote process must match the real group ID of the caller. (The permission required is exactly the same as that required to perform a ptrace(2) PTRACE_ATTACH on the remote process.)
On error, -1 is returned and errno is set appropriately.
These system calls were designed to permit fast message passing by allowing messages to be exchanged with a single copy operation (rather than the double copy that would be required when using, for example, shared memory or pipes).
#include <sys/uio.h> int main(void) { struct iovec local[2]; struct iovec remote[1]; char buf1[10]; char buf2[10]; ssize_t nread; pid_t pid = 10; /* PID of remote process */ local[0].iov_base = buf1; local[0].iov_len = 10; local[1].iov_base = buf2; local[1].iov_len = 10; remote[0].iov_base = (void *) 0x10000; remote[0].iov_len = 20; nread = process_vm_readv(pid, local, 2, remote, 1, 0); if (nread != 20) return 1; else return 0; }


Court Fixes Date For Hearing Of Case Against Social Media Bill
Human rights activist and lawyer; Tope Akinyode, had on November 12, filed an action in court against the proposed social medial bill, arguing that if enacted, the bill will encroach on fundamental human rights of citizens to free speech.
by SaharaReporters, New York
The Federal High Court, Ikoyi, Lagos, has fixed December 2, 2019 for hearing in the case filed against the enactment of the social media bill.
Human rights activist and lawyer; Tope Akinyode, had on November 12, filed an action in court against the proposed social medial bill, arguing that if enacted, the bill will encroach on fundamental human rights of citizens to free speech.
Joined as respondents in the suit are the National Assembly, Federal Republic of Nigeria, President of the Federal Republic of Nigeria and the Senate President.
The case with suit number: FHC/L/CS/2037/19 comes up before Justice Lema of Court 2 at the Federal High, Ikoyi Lagos.
The suit is praying the court for an order of perpetual injunction to restrain the respondents from embarking on further proceedings over the said bill.
According to Akinyode, the bill is repressive and difficult to maintain without a brutal violation of citizen’s right to free speech.

We just tried it (just for fun ;-), and for domain size 100 it's just
under 500 000 tuples (which takes about 10M of memory). For domain
size 200 it's around 4 000 000 tuples, which is still manageable with
under 100M of memory. Generation takes less than a second.
Even if you use more than one of these propagators, you can reuse the
same table for each one. So, you might actually want to try this, it
may work!
Cheers,
Guido

Danny Lee fires 62 to lead Mayakoba Golf Classic
by FSA EditorRunner-up last year, Danny Lee made a fine start to the Mayakoba Golf Classic in Mexico.
Danny Lee fired a nine-under 62 to grab a first-round lead at the Mayakoba Golf Classic on Friday.
The PGA Tour event finally got underway in Playa del Carmen after heavy rain led to Thursday’s scheduled play being washed out.
Lee, last year’s runner-up, pushed into a one-stroke lead after mixing eight birdies with an eagle and a bogey.
The New Zealander holds a lead over American duo Brendon Todd and Adam Long, who opened with fine eight-under 63s.
Vaughn Taylor, Mark Hubbard, Zach Johnson and Chris Baker are a shot further back after the opening round.

Due to the rain, the third and fourth rounds will begin on Sunday, while the event will finish on Monday if required.

Wales win sets up Slovakia date for Ireland
by Raf DialloWonder no more! Slovakia will be Ireland's opponents in the Euro 2020 playoffs next March.
The Boys in Green missed out on automatic qualification on Monday night after drawing 1-1 with Denmark.
That meant Mick McCarthy's side would be heading to the playoffs. The only thing that wasn't clear however was who the opponents would be given the relevance of Tuesday night's results.
The convoluted process which you can read here sees the UEFA Nations League playoffs playing a role in the qualification process.
Permutations
It was a little more complicated after the October results. But Ireland's fate became clearer this morning.
Ireland would have faced fellow Nations League B members Wales if the latter had lost to Hungary tonight.
However, two goals from Aaron Ramsey tonight secured the Welsh's place in a second consecutive European championship.
Wales' 2-0 home win put them second in qualifying Group E and sent them automatically to next summer's tournament.
Slovakia, also in Nations League B, beat Azerbaijan but stayed third in Group E.
Of the teams not qualified automatically for Euro 2020 from the Nations League, the League B rankings were as follows:
- Bosnia & Herzegovina
- Slovakia
- Republic of Ireland
- Northern Ireland
Given that first meets fourth and second plays third, Ireland will face a trip to Slovakia in the playoff semi-final.
Win that and McCarthy's side will take on the winner of Bosnia and Northern Ireland's semi.

When will Robert Moreno speak?
by BeSoccerRobert Moreno, the ex-Spain coach, did not want to give a press conference prior to the game against Romania and did not attend the meeting this Tuesday with Rubiales. When will he give his version of events?
The last few hours have been especially hectic for the Spanish national team. Before the game against Romania, news broke of Luis Enrique becoming the Spain manager once again.
The decision does not seem to have gone down well with Robert Moreno, who did not want to speak to the media and he cancelled his press conference after the comprehensive Spain victory and fantastic qualification campaign.
As 'Marca' reported, the coach said goodbye to the players in the dressing room and Rubiales called the media for a press conference this Tuesday at 12.30 in the Federation HQ in Las Rozas, Madrid. In the press conference, the RFEF president announced the return of Luis Enrique.
Beforehand, he had a meeting with Robert Moreno and Francisco Molina, but the now ex-coach did not attend it and the two lawyers have respected his decision not to turn up.

- Who has the most free-kicks goals: Messi or Cristiano?
- Luis Enrique returns to Spain national team
According to 'Mundo Deportivo', Robert Moreno will give his version of events and will respond to all the questions about what happened as soon as the termination of his contract is completed.
'Cadena SER' says that this will occur in the coming days and it looks like Robert Moreno will not continue in the RFEF.


2017:18 - External Relations Coordinator / Industry Event Coordinator
As the external relations coordinator, I was responsible for liaising with different societies especially in STEM subjects to maximize collaboration and reach via increased cross-talk, joint organization of events, etc. Together with these societies, we organised a 'Welcome Social' in the Oxford Townhall at the beginning of the academic year 2017-18. We received more than 200 students and staff members at this networking social that also hosted representatives from our industrial sponsors including Google, Facebook and Visa.
In my other role as the Industry event coordinator, I was responsible for organizing social and formal events to promote interaction between students and industry. The highlight of this role was the successful organisation of a day-long industrial visit to the Google DeepMind Headquarters in London for a record high of 62 Oxford grads, postgrads and visiting students.

2018:19 - Outreach/Scholarship Officer - I am in the final year of my DPhil study in 'AI for vision' and this is my second exciting year running with OxWoCS. As the outreach officer I am responsible for organising the annual networking social - an MPLS-wide welcome gathering where a host of women societies' introduce their agendas/events and industrial sponsors to the student population. Further, over the course of the year I will be involved in running a variety of workshops for technology dissemination in community at events such as University Open Days, Science Festivals.


Adding more backtesting nodes allows you to run more concurrent backtests. Depending on the design of your algorithm you can add more powerful nodes to run faster backtests. Nodes with more RAM allocation can handle more intensive operations such as machine learning and options data processing.
| Node Type | Number of Cores | Processing Speed | RAM |
|---|---|---|---|
| B-MICRO | 1 Cores | 3.7 Ghz | 8 GB |
| B2-8 | 2 Cores | 4.9 Ghz | 8 GB |
| B4-12 | 4 Cores | 4.9 Ghz | 12 GB |
| B8-16 | 8 Cores | 4.9 Ghz | 16 GB |


1 - HOW TO GET THE BETATEST DATASET
To access the betatest dataset:
README (contains information similar to what is in this document)
tarCODE (tar file contain code to read the data files,
also some interpolation routines)
Note:
and one of the following:
tarGLOBAL (contains data on a global 2.5 degree grid (i))
tarREGDOM (contains data on PIRCS 0.5 degree grid (ii))
tarPSTDOM (contains data on PIRCS polar stereographic grid (iii))
(depending on which set of LBC's are appropriate for your model)
Users of the PIRCS Beta-Test dataset should be
aware that
the provided variables are not stagggered, i.e., they
are all
at the same location. Because participant
models may use staggered grids horizontally
the width of the forcing zone will differ between
models.
For example, for the Arakawa B grid, the width for T
and q will
be 8 grid spacings, but 9 for U and V.
It is up to the participant to determine
which
PIRCS dataset suits their needs best.
It is recommended that participants use a bilinear
interpolation method
to interpolate the PIRCS grid-point data to their own
model's grid.
A bilinear interpolation subroutine based on
bint.f (described in
Manning and Haagenson, 1992) is part of program
indat_gen.f included
in the distributed dataset.
Various programs that read the files containing the
data are available.
Hopefully these programs are designed
so that they can be easily adapted by the participants
in their efforts
to convert the LBC's to their specific model
configuration.
These codes are in the file tarCODE in the directory /pub/PIRCS/BETA.RELEASE at the FTP site.
A listing and brief description of each program is included in the README
file of the directory READ.CODE (the directrory which the files are in,
when tarCODE is untarred).
The data are packed in integer format, and are in
slices ('horizontal') of constant pressure.
(25 mb being first, 1050 being last.) The data are
ordered as follows: surface pressure (Variable
code 001; units Pa), temperature (011; K), specific
humidity (051; kg/kg), u component of the
wind (033; m/s), and the v component of the wind (034;
m/s). This code "unpacks" the data, as they are
stored in a positive integer format; i.e., for each
field (horizontal slice) a maximum value
is determined, and this (and every other data point) is
multiplied by some scale factor to ensure
that the desired number of significant digits are to
the left of the decimal point. The
original data are extracted by subtracting the stored
data from the base value
and then dividing by
the scale factor. The
space requirements are minimized through the storage of
data as positive integers. To further
minimize the space requirements, data were compacted
using the standard UNIX "compress" (a
modified Lempel-Ziv algorithm popularized in Welch,
1984) command. While this choice of
packing procedure is not a meteorological "standard"
like GRIB or BUFR, we think that fewer
problems will be experienced in the short term.
For each 'horizontal' slice the data are ordered as
follows, as you look at it on the screen
(Note, this applies for the ordering of the forcing
data as well.)
SW Corner (1,1) .........................(XMAX,1) SE Corner
Note, in the read program, the I index is E-W, and the
J index is N-S.
(1,2) .........................(XMAX,2)
...........(I,J)...............
...............................
NW corner (1,YMAX).......................(XMAX,YMAX) NE Corner
3 - ISU BETATEST - SOME RESULTS
We ran the beta test at ISU using REGCM2 to produce
the output appearing
here.
( Figure
1.1(0.00833 MB) shows the time series of
the domain averaged temperature at a near-surface level
(sigma=0.9) for the BETAtest period as simulated by
REGCM2, and
( Figure
1.2(0.00833 MB) shows the time series of
the domain averaged wind speed at the same level. Figure 1.3
(below) shows the simulated
precipitation for the period.
It has been our experience that a 5 day integration
of REGCM2
(see Giorgi, et al., 1994) configured
for the PIRCS domain takes about
17 hours of cpu time on a DEC AXP 3000 workstation with
32 MB of assigned memory, and 32 hours with 10 MB
assigned.
The variables provided are surface pressure, T,
q, u, & v. They are provided
every 25 mb from 25 mb to 1050 mb. Also provided are
fields of the NCEP analysis topography for all
domains and topographic datasets for the limited
domains (ii) and (iii).
The latter were derived from a 30
minute dataset, and they have more detail than the
analysis topography.
Land-use datasets are also
provided for each of the limited domains, as well as
global SST's, soil moisture for the
limited domains, and the Great Lakes surface
temperatures.

from 00 UTC July 1 to
00 UTC July 6, 1988 as simulated by REGCM2 using the
PIRCS BETAtest
dataset.

BasicObject is the parent class of all classes in Ruby. It's an explicit blank class.
BasicObject can be used for creating object hierarchies independent of Ruby's object hierarchy, proxy objects like the Delegator class, or other uses where namespace pollution from Ruby's methods and classes must be avoided.
To avoid polluting BasicObject for other users an appropriately named subclass of BasicObject should be created instead of directly modifying BasicObject:
class MyObjectSystem < BasicObject end
BasicObject does not include Kernel (for methods like puts
) and BasicObject is outside of the namespace of the
standard library so common classes will not be found without using a full
class path.
A variety of strategies can be used to provide useful portions of the
standard library to subclasses of BasicObject. A subclass could include
Kernel
to obtain puts
, exit
, etc. A
custom Kernel-like module could be created and included or delegation can
be used via method_missing:
class MyObjectSystem < BasicObject DELEGATE = [:puts, :p] def method_missing(name, *args, &block) return super unless DELEGATE.include? name ::Kernel.send(name, *args, &block) end def respond_to_missing?(name, include_private = false) DELEGATE.include?(name) or super end end
Access to classes and modules from the Ruby standard library can be
obtained in a BasicObject subclass by
referencing the desired constant from the root like ::File
or
::Enumerator
. Like method_missing,
const_missing can be used to delegate constant lookup to
Object
:
class MyObjectSystem < BasicObject def self.const_missing(name) ::Object.const_get(name) end end
Boolean negate.
MJIT_FUNC_EXPORTED VALUE rb_obj_not(VALUE obj) { return RTEST(obj) ? Qfalse : Qtrue; }
Returns true if two objects are not-equal, otherwise false.
MJIT_FUNC_EXPORTED VALUE rb_obj_not_equal(VALUE obj1, VALUE obj2) { VALUE result = rb_funcall(obj1, id_eq, 1, obj2); return RTEST(result) ? Qfalse : Qtrue; }
Equality — At the Object level, #== returns
true
only if obj
and other
are the
same object. Typically, this method is overridden in descendant classes to
provide class-specific meaning.
Unlike #==, the equal?
method should never be overridden by subclasses as it is used to determine
object identity (that is, a.equal?(b)
if and only if
a
is the same object as b
):
obj = "a" other = obj.dup obj == other #=> true obj.equal? other #=> false obj.equal? obj #=> true
The eql? method returns true
if obj
and
other
refer to the same hash key. This is used by Hash to test members for equality. For any pair of
objects where eql? returns true
, the hash value of both
objects must be equal. So any subclass that overrides eql? should also
override hash appropriately.
For objects of class Object, eql? is synonymous with #==. Subclasses normally continue this tradition by aliasing eql? to their overridden #== method, but there are exceptions. Numeric types, for example, perform type conversion across #==, but not across eql?, so:
1 == 1.0 #=> true 1.eql? 1.0 #=> false
MJIT_FUNC_EXPORTED VALUE rb_obj_equal(VALUE obj1, VALUE obj2) { if (obj1 == obj2) return Qtrue; return Qfalse; }
Returns an integer identifier for obj
.
The same number will be returned on all calls to object_id
for
a given object, and no two active objects will share an id.
Note: that some objects of builtin classes are reused for optimization. This is the case for immediate values and frozen string literals.
BasicObject implements +__id__+, Kernel implements object_id
.
Immediate values are not passed by reference but are passed by value:
nil
, true
, false
, Fixnums, Symbols,
and some Floats.
Object.new.object_id == Object.new.object_id # => false (21 * 2).object_id == (21 * 2).object_id # => true "hello".object_id == "hello".object_id # => false "hi".freeze.object_id == "hi".freeze.object_id # => true

Invokes the method identified by symbol, passing it any arguments
specified. You can use __send__
if the name send
clashes with an existing method in obj. When the method is
identified by a string, the string is converted to a symbol.
BasicObject implements +__send__+, Kernel implements send
.
class Klass def hello(*args) "Hello " + args.join(' ') end end k = Klass.new k.send :hello, "gentle", "readers" #=> "Hello gentle readers"
VALUE rb_f_send(int argc, VALUE *argv, VALUE recv) { return send_internal_kw(argc, argv, recv, CALL_FCALL); }
Equality — At the Object level, #== returns
true
only if obj
and other
are the
same object. Typically, this method is overridden in descendant classes to
provide class-specific meaning.
Unlike #==, the equal?
method should never be overridden by subclasses as it is used to determine
object identity (that is, a.equal?(b)
if and only if
a
is the same object as b
):
obj = "a" other = obj.dup obj == other #=> true obj.equal? other #=> false obj.equal? obj #=> true
The eql? method returns true
if obj
and
other
refer to the same hash key. This is used by Hash to test members for equality. For any pair of
objects where eql? returns true
, the hash value of both
objects must be equal. So any subclass that overrides eql? should also
override hash appropriately.
For objects of class Object, eql? is synonymous with #==. Subclasses normally continue this tradition by aliasing eql? to their overridden #== method, but there are exceptions. Numeric types, for example, perform type conversion across #==, but not across eql?, so:
1 == 1.0 #=> true 1.eql? 1.0 #=> false
MJIT_FUNC_EXPORTED VALUE rb_obj_equal(VALUE obj1, VALUE obj2) { if (obj1 == obj2) return Qtrue; return Qfalse; }
Evaluates a string containing Ruby source code, or the given block, within
the context of the receiver (obj). In order to set the context,
the variable self
is set to obj while the code is
executing, giving the code access to obj's instance variables
and private methods.
When instance_eval
is given a block, obj is also
passed in as the block's only argument.
When instance_eval
is given a String
, the
optional second and third parameters supply a filename and starting line
number that are used when reporting compilation errors.
class KlassWithSecret def initialize @secret = 99 end private def the_secret "Ssssh! The secret is<EMAIL_ADDRESS>end end k = KlassWithSecret.new k.instance_eval { @secret } #=> 99 k.instance_eval { the_secret } #=> "Ssssh! The secret is 99." k.instance_eval {|obj| obj == self } #=> true
static VALUE rb_obj_instance_eval_internal(int argc, const VALUE *argv, VALUE self) { VALUE klass = singleton_class_for_eval(self); return specific_eval(argc, argv, klass, self, RB_PASS_CALLED_KEYWORDS); }
Executes the given block within the context of the receiver (obj).
In order to set the context, the variable self
is set to
obj while the code is executing, giving the code access to
obj's instance variables. Arguments are passed as block
parameters.
class KlassWithSecret def initialize @secret = 99 end end k = KlassWithSecret.new k.instance_exec(5) {|x| @secret+x } #=> 104
static VALUE rb_obj_instance_exec_internal(int argc, const VALUE *argv, VALUE self) { VALUE klass = singleton_class_for_eval(self); return yield_under(klass, self, argc, argv, RB_PASS_CALLED_KEYWORDS); }
Invoked by Ruby when obj is sent a message it cannot handle.
symbol is the symbol for the method called, and args are
any arguments that were passed to it. By default, the interpreter raises an
error when this method is called. However, it is possible to override the
method to provide more dynamic behavior. If it is decided that a particular
method should not be handled, then super should be called, so that
ancestors can pick up the missing method. The example below creates a class
Roman
, which responds to methods with names consisting of
roman numerals, returning the corresponding integer values.
class Roman def roman_to_int(str) # ... end def method_missing(symbol, *args) str = symbol.id2name begin roman_to_int(str) rescue super(symbol, *args) end end end r = Roman.new r.iv #=> 4 r.xxiii #=> 23 r.mm #=> 2000 r.foo #=> NoMethodError
static VALUE rb_method_missing(int argc, const VALUE *argv, VALUE obj) { rb_execution_context_t *ec = GET_EC(); raise_method_missing(ec, argc, argv, obj, ec->method_missing_reason); UNREACHABLE_RETURN(Qnil); }
Invoked as a callback whenever a singleton method is added to the receiver.
module Chatty def Chatty.singleton_method_added(id) puts "Adding #{id.id2name}" end def self.one() end def two() end def Chatty.three() end end
produces:
Adding singleton_method_added Adding one Adding three
static VALUE rb_obj_dummy1(VALUE _x, VALUE _y) { return rb_obj_dummy(); }
Invoked as a callback whenever a singleton method is removed from the receiver.
module Chatty def Chatty.singleton_method_removed(id) puts "Removing #{id.id2name}" end def self.one() end def two() end def Chatty.three() end class << self remove_method :three remove_method :one end end
produces:
Removing three Removing one
static VALUE rb_obj_dummy1(VALUE _x, VALUE _y) { return rb_obj_dummy(); }
Invoked as a callback whenever a singleton method is undefined in the receiver.
module Chatty def Chatty.singleton_method_undefined(id) puts "Undefining #{id.id2name}" end def Chatty.one() end class << self undef_method(:one) end end
produces:
Undefining one
static VALUE rb_obj_dummy1(VALUE _x, VALUE _y) { return rb_obj_dummy(); }

Javascript in Org-Babel
Beginning
This is a test of running javascript in org-babel blocks. For some reason I couldn't find any documentation about setting it up so this is also a place for me to collect what to do.
Note: I actually did use this org-babel page for some of it, but it wasn't enough for me to really figure out what was going on.
Middle
Prerequites
Node
Since javascript is an interpreted language you need an interpreter to run code blocks. Org-babel assumes you're using node.js so you need to install it and make sure it's on the PATH
. They do support debian-based systems (including Ubuntu, which I use) but they don't use the traditional PPA system. Instead they have different installs for the different versions - but they do have a Long-Term Support (LTS) version which I'm hoping updates so that's what I installed.
curl -sL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
sudo apt-get install -y nodejs
As of this writing it install version 12.19.0, versus the Ubuntu 20.04 version of 10.19.0.
init.el
Besides installing node you have to make sure that you add js
to your org-babel set up.
(org-babel-do-load-languages
'org-babel-load-languages

Try It
Now that it's set up you can execute javascript in org-babel code blocks, designating them as js
blocks (e.g. #+begin_src js :results output :exports both
).
Here's a simple output block.
console.log("test")
test
var x = 'apple'
console.log(x)
var y = 'banana'
console.log(x + y)
apple applebanana
One thing to note is that this doesn't seem create sessions that persist across blocks. Even though I defined x
and y
in the previous block, this next block raises an error because it doesn't think I've defined y
.
console.log(y)
console.log(x)
If you try and put a session argument in the org-babel header you'll get a message saying "Session evaluation with node.js not supported". According to the org-babel-js documentation you can put in special headers to run the code in an alternate REPL, but I tried it and the output ends up in a separate buffer rather than showing up in the org-document, which seems to kind of lessen the usefulness of it. Also the js-comint version dumps extra text into the REPL as well.
End
Okay, so this was a very basic hello world for javascript in emacs. The lack of sessions is kind of disappointing, but I don't know how useful this is going to be, anyway, since javascript is so tied to the browser, but there it is.


Create another page function (we don't need start=True this time). To add this as an option to an existing page, pass an argument to the parent page which has the same name as the new page function. Use Grimoire's builtin link function to create a link to the page.
You can add as many options as you like by continuing to add arguments to a page function's signature.
from grimoire.templates import link
@app.page(start=True)
def start(state, second):
return Div(
P("Hello, Grimoire!"),
Ul(Li(link("Go to the second page", second)))
), state
@app.page()
def second(state):
return Div(
P("I'm the second page.")
), state

This notebook demonstrates quantum teleportation. We first use Qiskit's built-in simulator to test our quantum circuit, and then try it out on a real quantum computer.
Alice wants to send quantum information to Bob. Specifically, suppose she wants to send the state $\vert\psi\rangle = \alpha\vert0\rangle + \beta\vert1\rangle$ to Bob. This entails passing on information about $\alpha$ and $\beta$ to Bob.
There exists a theorem in quantum mechanics which states that you cannot simply make an exact copy of an unknown quantum state. This is known as the no-cloning theorem. As a result of this we can see that Alice can't simply generate a copy of $\vert\psi\rangle$ and give the copy to Bob. Copying a state is only possible with a classical computation.
However, by taking advantage of two classical bits and entanglement, Alice can transfer the state $\vert\psi\rangle$ to Bob. We call this teleportation as at the end Bob will have $\vert\psi\rangle$ and Alice won't anymore. Let's see how this works in some detail.
Step 1: Alice and Bob create an entangled pair of qubits and each one of them holds on to one of the two qubits in the pair.
The pair they create is a special pair called a Bell pair. In quantum circuit language, the way to create a Bell pair between two qubits is to first transfer one of them to the Bell basis ($|+\rangle$ and $|-\rangle$) by using a Hadamard gate, and then to apply a CNOT gate onto the other qubit controlled by the one in the Bell basis.
Let's say Alice owns $q_1$ and Bob owns $q_2$ after they part ways.
Step 2: Alice applies a CNOT gate on $q_1$, controlled by $\vert\psi\rangle$ (the qubit she is trying to send Bob).
Step 3: Next, Alice applies a Hadamard gate to $|\psi\rangle$, and applies a measurement to both qubits that she owns - $q_1$ and $\vert\psi\rangle$.
Step 4: Then, it's time for a phone call to Bob. She tells Bob the outcome of her two qubit measurement. Depending on what she says, Bob applies some gates to his qubit, $q_2$. The gates to be applied, based on what Alice says, are as follows :
00 $\rightarrow$ Do nothing
01 $\rightarrow$ Apply $X$ gate
10 $\rightarrow$ Apply $Z$ gate
11 $\rightarrow$ Apply $ZX$ gate
Note that this transfer of information is classical.
And voila! At the end of this protocol, Alice's qubit has now teleported to Bob.
In this notebook, we will give Alice a secret state $\vert\psi\rangle$. This state will be generated by applying a series of unitary gates on a qubit that is initialized to the ground state, $\vert0\rangle$. Go ahead and fill in the secret unitary that will be applied to $\vert0\rangle$ before passing on the qubit to Alice.
secret_unitary = 'hz'
If the quantum teleportation circuit works, then at the output of the protocol discussed above will be the same state passed on to Alice. Then, we can undo the applied secret_unitary (by applying its conjugate transpose), to yield the $\vert0\rangle$ that we started with.
We will then do repeated measurements of Bob's qubit to see how many times it gives 0 and how many times it gives 1.
In the ideal case, and assuming our teleportation protocol works, we will always measure 0 from Bob's qubit because we started off with $|0\rangle$.
In a real quantum computer, errors in the gates will cause a small fraction of the results to be 1. We'll see how it looks.

since for a unitary u, u^dagger u = I.
'''
apply_secret_unitary(secret_unitary, q[2], qc, dagger=1)
qc.measure(q[2], c[2])
It's always a good idea to draw the circuit that we have generated in code. Let's draw it below.
qc.draw(output='mpl')
backend = Aer.get_backend('qasm_simulator')
job_sim = execute(qc, backend, shots=1024)
sim_result = job_sim.result()
measurement_result = sim_result.get_counts(qc)
print(measurement_result)
plot_histogram(measurement_result)
Note that the results on the x-axis in the histogram above are ordered as $c_2c_1c_0$. We can see that only results where $c_2 = 0$ appear, indicating that the teleporation protocol has worked.
You will now see how the teleportation algorithm works on a real quantum computer. Recall that we need one qubit for $\vert\psi\rangle$, one qubit for Alice, and one qubit for Bob, for a total of three qubits.
# First, see what devices we are allowed to use by loading our saved accounts

from qiskit.providers.ibmq import least_busy
backend = least_busy(provider.backends(simulator=False))
job_exp = execute(qc, backend=backend, shots=8192)
exp_result = job_exp.result()
exp_measurement_result = exp_result.get_counts(qc)
print(exp_measurement_result)
plot_histogram(exp_measurement_result)
As we see here, there are a few results that contain the case when $c_2 = 1$ in a real quantum computer. These arise due to errors in the gates that were applied. Another source of error is the way we're checking for teleportation - we need the series of operators on $q_2$ to be exactly the inverse unitary of those that we applied to $q_0$ at the beginning.
In contrast, our simulator in the earlier part of the notebook had zero errors in its gates, and allowed error-free teleportation.
error_rate_percent = sum([exp_measurement_result[result] for result in exp_measurement_result.keys() if result[0]=='1']) \
* 100./ sum(list(exp_measurement_result.values()))
print("The experimental error rate : ", error_rate_percent, "%")
