BY EDWIN JAHIEL
THREE KINGS (1999) ** 1/2 . Written and directed by David O. Russell from a story by John Ridley. Photography, Newton Thomas Sigel. Editing, Robert K. Lambert. Production design,, Catherine Hardwicke. Music, Carter Burwell. Producers, Charles Roven, Paul Junger Witt, Edward L. McDonnell. Cast: George Clooney (Special Forces Capt. Archie Gates), Mark Wahlberg (Sgt. Troy Barlow), Ice Cube (Staff Sgt. Chief), Spike Jonze (Conrad Vig), Nora Dunn (Adriana Cruz), Jamie Kennedy (Walter), Mykelti Williamson (Colonel Horn), Cliff Curtis (Amir), Said Taghmaoui (Captain Sa'id) et al. A Warners release. 114 minutes. R (language, shocking violence, sex)
In a film as with all else, novelty for novelty's sake isn't much. But then again, novelty of any kind may open doors for other creators and works. David O. Russell's first feature, the low-budget Spanking the Monkey, was daringly original. It and made the writer-director more than just promising. His next film was Flirting With Disaster, neither daring nor a minor landmark, but clever (though without brilliance or depth), inventive (but not really original), and amusing.
The title Three Kings is ironic. It calls to mind We Three Kings from Orient Are. But these kings don't bear gifts. They are taking gold away. In any case they are four, not three. A redneck yahoo from Texas is excluded from the title --which goes to show how logic is sacrificed at the altar of catchy titles.
Desert Storm is ending. Is the Gulf War really over? Is there a truce? What's up, Doc? It's all muddled, but the U.S. soldiers are celebrating anyway their return-home-to be. They live it up like fraternity boys, with booze and clowning and rap music.  But wait a moment. Special Forces Captain Gates (George Clooney, in fine mettle) is in a tent, vigorously copulating with the female assistant to Adriana. Adriana is an ace reporter for a TV network (invented).
The lively though not lovely start also includes encounters with "ragheads," captives treated like dirt, Iranians in uniform and others. Sometimes the soldiers shoot first, then wonder if the natives were friendly (anti-Saddam), foes or simply guys surrendering Ugh.
All this sets the tone. Mostly, it introduces the plot. An anal (don't ask) document on (in) a captive officer turns out to be the map of gold bars looted by Iraq from Kuwait. That's the stuff dreams (cf. The Maltese Falcon and Treasure if Sierra Madre) are made of. Neat, ain't it?
The next, inevitable step is for Captain Gates to lead a quartet of men (the old movie mix of motley guys) to the "liberation" of the golden stash. It could buy endless visits to Disney, Inc. at home.
Then comes non-stop action, compounded by a baffling mix of elite troops still faithful to Saddam --or still afraid of him, deserters, an anti-Saddam Resistance (which was news to me), innocent women and children caught in cross-fire, underground treasure troves. Not only gold bars but Kuwaiti jewelry, absurd refrigerators, radios and tutti quanti). Plus occasional people from whatever is the "other" side being interrogated under torture. And later, another stash, this time of luxurious, shiny Kuwaiti limousines and sports cars. Enough, enough.
In addition, the Americans are being stalked by news-supergal Adriana (and her cameraman). She's been Emmy-nominated multiple times, but has always been a bridesmaid, never a bride. This is her big chance: The Scoop.
Shot with a real (or a pretend) 16 millimiter hand-held movie camera (unless it is supposed to be video), the sights have that typical graininess, jerkiness and relative un-sharpness of news footage. A clever idea which adds immediacy to the action. But analyze it and you'll have to conclude that it's still the old Eye of God, except that it is not mounted on a studio tripod. (There are also shots of sea-birds soaked in oil as a result of blown-up oil wells by the Iraqis. Looks to me like footage from the Werner Herzog apocalyptic documentary).
In addition (again) the four soldiers must be AWOL, given the time frame. In re-addition, we get the old cliche characterizations of the group's individuals.
From the point of view of the narrative, the well-intentioned desire to show the madness and chaos of war and its aftermath results in much murkiness and confusion. The audiences of this movie will no doubt be heavy with young persons who were pre-teens or early teens during the Gulf War --and know next to nothing about it. I suppose that like most viewers of action flicks they don't ask themselves questions but bask in the physical scenes before their eyes. But those non-kids who do exercise their logic and whatever they know of history, are bound (as I did) to spend much time trying to figure out who's who,what and where.
Violence is most graphic, gory and too often gratuitous here. It is effective in its use of firearms, mines, poison gas, vehicles and all --but it lacks Sam Peckinpah's ballet-ism or even the montage of Bonnie and Clyde's slow-motion rain of bullets. Everything seems to be larger and faster than life. and faster. Sort it out if you can: most of the males, on all sides, are primitive or ferocious. So much for humanism.
The narrow subject is greed, which is OK. But, like a savage kind of M*A*S*H, there's a pretty continuous thread of comedy running through, with mixed results. And, shades of umpteen movies about fortune-hunting, the conclusion lapses into deja vu sentimentality. The three American survivors will give up their gold in exchange of authorities allowing a procession of "good" (read anti-Saddam) Iraqis to enter a sanctuary at the Iranian border.
Makes you feel good, as it had in other, different films, doesn't it?
The high-budget transformation of locations in the American Southwest and in Mexico into the Arabian desert is remarkable. The performers are good, including those who play Iraqis. So is the varied music score by Carter Burwell.

Covid-19 is a highly contagious viral disease caused by coronavirus. Originated from Wuhan city of China it became a pandemic in so short time that the whole world got worried.  There's no medicine for this virus as of now but prevention is better than cure so We all have to face it together by maintaining social distancing.
hello again


Servants boiled along the halls as Nynaeve ran, shouting frantic questions. They might not be able to sense channeling, but they had certainly felt the palace being torn half apart. She threaded her way through, just one more serving woman in a panic as far as they were concerned.
Saidar faded from her as she sped down corridors and across courtyards. Holding on to anger was difficult when she was increasingly uneasy for Elayne. If the Black sisters had found her . . . Who knew what they had beside the balefire ter’angreal? The list they had been given certainly did not give a use for everything.
Once she saw Liandrin, with her pale honey braids, and Rianna, with that white streak in her black hair, hurrying down a flight of broad marble stairs; she could not see the glow of saidar around them, but from the way servants cried out and leaped from their path, they were whipping a way clear for themselves with the Power. It made her glad she had not tried to cling to the Source herself; they would have picked her out of the throng in an instant by the glow, and until she had some rest, she was not up to facing either of them, much less both. She had what she had come for. They had to wait.
The crowd thinned and disappeared by the time she reached the narrow hall on the west side of the palace that was the meeting place. The others were waiting for her beside a small, bronze-studded door fastened with a large iron lock. Including Amathera, standing very straight, wearing a light linen cloak with the hood up. The Panarch’s white dress might pass for serving-woman garb if you did not look closely enough to see it was silk, and the veil that did not hide her face was certainly servant’s linen. The sound of shouts came muffled through the door. Apparently the riot was still going on. Now if only the men were doing the rest of their part.
Ignoring Egeanin, Nynaeve threw her arms around Elayne in a quick hug. “I was so worried. Did you have any trouble?”
“Not a bit,” Elayne replied. Egeanin shifted slightly, and the younger woman gave her a meaningful look, then added, “Amathera did cause a little problem, but we sorted it out.”
Nynaeve frowned. “Trouble? Why would she give trouble? Why would you give trouble?” That last was for the Panarch, who held her head high, refusing to look at anyone. Elayne seemed as reluctant.
It was the Seanchan woman who answered. “She tried to sneak off to rouse her soldiers to harry the Darkfriends out. After she had been warned.” Nynaeve refused to look at her.
“Do not scowl so, Nynaeve,” Elayne said. “I chased her down quickly, and we had a little talk. I think she is in perfect agreement with me now.”
The Panarch’s cheek twitched, “I am in agreement, Aes Sedai,” she said hastily. “I will do exactly as you say, and I will provide papers that should make even the rebels let you pass unhindered. There is no need for more . . . talking.”
Elayne nodded as if all of that made sense, motioning for the women to be quiet. Whereupon the Panarch obediently closed her mouth. A trifle sullenly, but perhaps that was just the shape of her mouth. Clearly there had been some very odd goings on, and Nynaeve intended to find the bottom of them. Later. The narrow hallway was still empty in both directions, but panicked shouts still echoed from deeper in the palace. The mob rumbled beyond the small door.
“But what of you?” Elayne went on with a frown. “You were supposed to be here half an hour ago. Did you cause all of this? I felt two women channeling enough of the Power to shake the palace down, and then a bit later someone did try to shake it down. I thought it must be you. I had to restrain Egeanin from going to find you.”
Egeanin? Nynaeve hesitated, then made herself touch the Seanchan woman’s shoulder. “Thank you.” Egeanin looked as though she did not quite understand herself what she had done, but she gave a quick nod. “Moghedien found me, and because I was worrying about how to bring her out for trial, Jeaine Caide nearly took my head off with balefire.” Elayne gave a small squeak, and she hurried to reassure her. “It didn’t really come close to me.”
“You captured Moghedien? You captured one of the Forsaken?”
“Yes, but she got away.” There. She had admitted everything. Conscious of all their eyes on her, she shifted uncomfortably. She did not like being in the wrong. She especially did not like being in the wrong when it was she who had pointed out that it was wrong in the first place. “Elayne, I know what I said about being careful, but once I had her in my hands, it seemed all I could think of was bringing her to trial.” Taking a deep breath, Nynaeve made her voice apologetic. She hated doing that. Where were those fool men? “I endangered everything because I didn’t keep my mind on what we were about, but please don’t scold me.”
“I won’t,” Elayne said firmly. “So long as you remember to be careful in the future.” Egeanin cleared her throat. “Oh, yes,” Elayne added hastily. The waiting seemed to be getting to her; there were spots of color in her cheeks. “Did you find the collar, and the seal?”
“I have them.” She patted her pouch. The shouting outside seemed to be getting louder. And the shouts echoing down the halls were, too. Liandrin must be turning the palace upside down to find out what had happened. “What is keeping those men?”
“My Legion,” Amathera began. Elayne looked at her, and she snapped her mouth shut. Whatever talk they had had must have been something. The Panarch was pouting like a girl afraid of being sent to bed without supper.
Nynaeve glanced at Egeanin. The Seanchan woman was watching the door intently. She had wanted to come after her. Why won’t she let me hate her? Am I so different from her?
Suddenly the door swung open. Juilin pulled two thin bent metal rods out of the lock and straightened from a crouch.  “Hurry. We must be away from here before it gets out of hand.”
Staring past him wide-eyed, Nynaeve wondered what he considered out of hand. Bayle Domon’s sailors, at least three hundred of them, formed a semicircle two deep about the door, Domon himself waving a cudgel, shouting to encourage them. He had to shout for the roar that filled the wide street. Men jostled and struggled and shouted in a seething mass, barely held back by the sailors’ clubs and staffs. Not that they were really interested in the sailors. Scattered through the crowd, clumps of mounted Whitecloaks swung their swords at men crowding them with pitchforks and barrel staves and bare hands. Showers of stones fell around them, sometimes banging off a helmet, but silently in the uproar. A lone Whitecloak’s horse suddenly screamed and reared, and toppled over backward; it scrambled to its feet quickly, minus its rider. Other riderless animals dotted the mass of men. Was this what they had set off just to cover themselves?  Men were dying out there, surely.
“Will you women move?” Thom called, waving for them to come out. He had a bleeding gash over one bushy eyebrow, perhaps from a stone, and his brown cloak would not even do for the ragbag now. “If the Panarch’s Legion ever stops running, this could grow messy.”
Amathera made a startled sound, just before Elayne pushed her firmly out. Nynaeve and Egeanin followed, and as soon as all four women were out, the sailors folded in around them in a tight ring that began straggling away from the palace. It was all Nynaeve could do to keep her feet, jostled by the men who were trying to protect her. Once Egeanin slipped and nearly fell. Nynaeve caught her arm, helped her back up, and got a grateful grin. We are not so different, she thought. Not the same, but not all that different. She did not have to make herself smile encouragingly at the Seanchan woman.
The milling mass lasted several streets away from the palace, but once they broke clear the narrow twisting ways were almost empty. Those who were not actually involved in the riot seemed wise enough to stay clear of it. The sailors spread out a little, giving the women more room. Any straggler who looked in their direction got hard stares, though. The streets of Tanchico were still the streets of Tanchico. Somehow that surprised Nynaeve. It seemed that she had been weeks inside the palace. Surely the city should be different.
When the babble began to fade behind them, Thom managed a quite elegant bow to Amathera as he limped along. “An honor, Panarch,” he said. “If I may be of any service, you have only to speak.”
Shockingly, Amathera glanced at Elayne, grimaced slightly, and said, “You mistake me, good sir. I am only a poor refugee from the countryside, rescued by these good women.”
Thom exchanged startled looks with Juilin and Domon, but when he opened his mouth, Elayne said, “Could we get on to the inn, Thom? This is hardly the place for conversation.”
When they reached the Three Plum Court, it was scarcely less surprising to hear Elayne introduce the Panarch to Rendra as Thera, a refugee with no money who needed a pallet, and maybe some work to earn her meals. The innkeeper shrugged resignedly, but as she led “Thera” away to the kitchens she was already telling the woman what lovely hair she had and how pretty she would look in the right dress.
Nynaeve waited until the rest of them were in the Chamber of Falling Blossoms with the door closed before saying, “Thera? And she went along! Elayne, Rendra will have the woman serving at table in the common room!”
Elayne did not seem surprised. “Yes, very likely.”  “It was not difficult to convince Amathera she should stay in hiding for a few days. It really isn’t that far from ‘The Panarch is dead’ to ‘Death to the Panarch.’ I think seeing the riot helped, too. She doesn’t want to depend on Andric to put her back on her throne; she wants her own soldiers to do it, even if it means hiding until she can get in touch with the Lord Captain of the Legion. I believe Andric is in for a surprise with her. It is too bad he doesn’t surprise her. She deserves it.” Domon and Juilin exchanged glances, shook their heads uncomprehendingly. Egeanin nodded to herself as if she, at least, understood, and approved.
“But why?” Nynaeve demanded. “You may have been upset because she sneaked off on her own, but this? How did she manage that anyway, with two of you watching her?” Egeanin’s eyes flickered toward Elayne, so quickly Nynaeve was not sure she had really seen it.
Elayne bent to rub the sole of one foot. It must have hurt; there was red in her cheeks. “Nynaeve, the woman has no idea what the lives of the common people are like.” As if she did! “She does seem to have a true concern for justice—I think she does—yet it did not bother her at all that there was enough food in the palace for a year. I mentioned the soup kitchens, and she did not know what I was talking about! A few days working for her supper will do her good.” Stretching her legs under the table, she worked her bare toes. “Oh, that does feel good. Not that she’ll have many, I suppose. Not if she is to rally the Panarch’s Legion to pry Liandrin and the others out of the palace. A pity, but there it is.”
“Well, she has to,” Nynaeve told her firmly. It was good to sit down, though she could not understand the girl’s concern with her feet. They had hardly walked at all today. “And the sooner the better. We need the Panarch, and not in Rendra’s kitchen.” She did not think there was any need to worry about Moghedien. That woman had had every opportunity to come into the open, after she had freed herself. That still puzzled her; she must have been careless in tying off the shield. But if Moghedien had been unwilling to face her then, when she must have known Nynaeve was nearly exhausted, she could not think the woman would come after them. Not for something she seemed to think was not worth very much. The same did not apply to Liandrin, however. If Liandrin figured out half of what had happened, she would be hunting them.
“The justice of the Daughter-Heir,” Thom murmured, “may yet supersede the justice of the Panarch. There were men streaming in through that door as we left, and I think some had already got in the front. I saw smoke coming out of several windows. By tonight, little more than a fire-gutted ruin will remain. No need for soldiers to chase the Black Ajah, and thus ‘Thera’ can have her few days to learn the lesson you want to teach. You will make a fine queen one day, Elayne of Andor.”
Elayne’s pleased smile faded as she looked at him. Rising to pad around the table, she rummaged in his coat pockets for a kerchief and began dabbing blood from his forehead despite his protests.
“Could we at least see what we risked our necks for?” he said when it became clear Elayne was going to do exactly as she wished.
Opening her belt pouch, Nynaeve laid the contents out on the table, the black-and-white disc that helped hold the Dark One’s prison shut, the collar and bracelets that sent ripples of sorrow through her before she could lay them down. Everyone gathered close to stare.
Domon fingered the seal. “I did own a thing like this once.”
Nynaeve doubted it. Only seven had been made. Three were broken now, cuendillar or no. Another was in Moiraine’s hands. Four surviving. How well could four keep that prison at Shayol Ghul locked? A shivery thought.
Egeanin touched the collar, pushed the bracelets away from the collar. If she felt the emotions trapped in them, she did not show it. Perhaps that sensitivity came only with the ability to channel. “It is not an a’dam,” the Seanchan woman said. “That is made of a silvery metal, and all of one piece.”
Nynaeve wished she had not mentioned a’dam. But she never wore the bracelet of one. And she did let that poor woman she told us about go. Poor woman. She—this Bethamin—was the one who controlled women with an a’dam. Egeanin had showed more mercy than Nynaeve would have. “It is as least as much like an a’dam as you and I are alike, Egeanin.” The woman looked startled, but after a moment she nodded. Not so different. Two women, each doing the best she could.
“Do you mean to keep on pursuing Liandrin?” Juilin seated himself, arms folded on the table, studying the things there. “Whether or not she is chased out of Tanchico, she is still out there. And the others. But these seem too important to leave lying about. I am only a thief-catcher, but I would say these must be taken to the White Tower for safekeeping.”
“No!” Nynaeve was startled at her own vehemence. So were the others, by the way they stared at her. Slowly she picked up the seal and replaced it in her pouch. “This goes to the Tower. But that . . . ” She did not want to touch the black things again. If those were in the Tower, Aes Sedai might decide to use them just as the Black Ajah had intended to. To control Rand. Would Moiraine? Siuan Sanche? She would not take the chance. “That is too dangerous to risk it ever falling back into the hands of Darkfriends. Elayne, can you destroy them? Melt them. I don’t care if they burn through the table. Just destroy them!”
“I see what you mean,” Elayne said with a grimace. Nynaeve doubted she did—Elayne believed in the Tower wholeheartedly—but she believed in Rand, too.
Nynaeve could not see the glow of saidar, of course, but the intent way the girl stared at the vile objects told her she was channeling. The bracelets and necklace lay there. Elayne frowned; her stare became more intent. Abruptly she shook her head. Her hand poised hesitantly for a moment, close to one of the bracelets, before picking it up. And dropped it again, with a gasp. “It feels . . .  ” Drawing a deep breath, she said, “I did what you asked, Nynaeve. A hammer would be burning a puddle for the Fire I wove into it, but it isn’t even warm.”
So Moghedien had not lied. Doubtless she had thought there was no need, that she would surely win. How did the woman get loose? But what to do with the things? She was not going to let them fall into anyone’s hands.
“Master Domon, do you know a very deep part of the sea?”
“I do, Mistress al’Meara,” he said slowly.
Gingerly, trying not to feel the emotions, Nynaeve shoved the collar and bracelets across the table to him. “Then drop these into it, where no one can ever fish them out again.”
After a moment, he nodded. “I will.” He stuffed them into his coat pocket hurriedly, clearly disliking to touch something that must have to do with the Power. “In the deepest part of the sea I do know, near the Aile Somera.”
Egeanin was frowning at the floor, no doubt thinking about the Illianer leaving. Nynaeve had not forgotten the woman calling him “a properly set-up man.” She herself felt like laughing. It was all but done. As soon as Domon could sail, the hateful collar and bracelets would be gone forever. They could leave for Tar Valon. And then . . . Then back to Tear, or wherever al’Lan Mandragoran was. Facing Moghedien, realizing how close she had been to being killed or worse, only made her urgency to deal with him greater. A man she had to share with a woman she hated, but if Egeanin could look fondly on a man she once took prisoner—and Domon was certainly eyeing her with interest—and if Elayne could love a man who would go mad, then she could puzzle out some way to enjoy what she could have of Lan.
“Shall we go downstairs and see how ‘Thera’ is taking to being a servant?” she suggested. Soon for Tar Valon. Soon.


Grouping segments into tablespaces is one of the most complex tasks in a DBA's job. There are not normally segment level I/O statistics available, so a detailed understanding of the physical data model and its usage characteristics is required. There may also be numerous competing factors to weigh together.
Firstly, segments should not be placed together in a tablespace if they have incompatible I/O patterns. Otherwise your ability to optimize the I/O for that tablespace, as outlined in our series of disk configuration tips, will be compromised. There are two particular access patterns that should be catered for.
Segments that exhibit a predominantly sequential I/O pattern, such as single threaded full table scans or fast full index scans, should be separated into their own tablespaces. If possible, the datafiles for these tablespaces should be placed on disks in such a way as to maximize the probability that there will be no concurrent access to those disks when these segments are being scanned. Service times can be dramatically improved if such I/O separation can be achieved, because very little seek time will be required, and many disk reads will be satisfied immediately from the track buffers.
If RAID-5 data storage is a consideration, segments that are written to intensively, such as by parallel direct loads or bulk updates, should be separated into distinct tablespaces. If possible, the datafiles for these tablespaces should be placed on faster mirrored disk rather than on RAID-5.
There is also a case for separating read-only segments so that their tablespaces can be made read-only. This does not affect I/O performance directly, but can have a big impact on backup times.
Secondly, segments should not be placed together if they might need to be separated during disk load balancing. There are two main reasons why segments might need to be separated.
Two segments with heavy I/O requirements should not be placed in the same tablespace. Otherwise it will not normally be possible to spread the load by moving datafiles. Even if the tablespace has multiple datafiles, Oracle will attempt to spread the load evenly between them by cycling the extents for each segment around the datafiles. While it is possible to move segments between datafiles, the lack of segment level I/O statistics makes it difficult to know which segments to move and where to move them.
In general, it is safest to separate related segments into separate tablespaces. However, not all query execution plans that access two related segments cause repeated alternating access between them. For example, two related tables may reside on the same disks if they are only ever joined using a sort-merge join or hash join, because these query execution plans cause the tables to be accessed in series. The same applies to index merges. However, a nested loops join normally involves repeated access to first the outer table, then the index on the inner table, and then the inner table itself. If any 2, or all 3, of these segments reside on the same disks, head thrashing will occur and will result in poor I/O service times.
Similarly, an index range scan normally involves repeated alternating access to the index and the table, and partition parallel execution plans normally involve concurrent access to multiple partitions of the same index. These execution plans can also cause disk head thrashing if related segments have not been duly separated. Because of these factors, it is safest to always separate related segments into distinct tablespaces, unless you are confident that the optimizer will always choose an execution plan that does not involve repeated alternating access between the segments.
These are not the only factors that should be considered when grouping segments into tablespaces. If a fixed extent size policy is in place, then extent size requirements must be considered. Another particularly important consideration is partitioning for parallel server databases. Segments that are predominantly accessed from one instance should be separated from segments that are predominantly accessed from another.
One final consideration is statistics. If major application segments are each placed into their own tablespace, the V$FILESTAT statistics can be guaranteed to correspond exactly with the I/O against those segments. If so, it is possible to monitor trends in the I/O to these tables and indexes and thus determine when they should be rebuilt. These statistics can also assist with disk load balancing.

This is a result of a collaborative effort with Dr Sean Davis of NCI Center for Cancer Research and John Readey of the HDF Group. The basic idea is that Sean’s OmicIDX and BigRNA APIs have been used to create snapshots of cancer-related RNA-seq studies and associated metadata.
The quantifications were set up for global distributon via the HDF Scalable Data Service (HSDS), and SummarizedExperiment interfaces were set up via the restfulSE package.
The user can click on a study to add it to the “cart” which will define a RESTful SummarizedExperiment for downloading. The SummarizedExperiment will include data and metadata from all selected studies, but assay data will not be downloaded. Instead, the assay data are referenced through the DelayedArray protocol, retrieved, ultimately, as needed via HSDS.
Tab panels provide searchable tables of all available sample-level metadata.
The “about” tab describes some details of metadata handling.

How to solve the traffic jams problem?
As standards of people's living rise and the economy grow, the number of vehicles has been increasing a lot in big cities. This situation results in more and more traffic jams on the street. Heavy traffic has become a main concern of the society.
People have come up with a number of solutions to solve the problem. One is to improve public transportation. For example, the government can open up more bus routes and subway routes and reduce their ticket price. In this case, more and more people would take public transportation instead of driving their cars. But clearly, this will cost a lot and need generous funding of the government.
Another way to relieve traffic congestions is to charge extra congestion fee and impose car restriction measure to control vehicle flow, such as restrictions based on the last digit of license plate numbers. However, one drawback to this approach is that the wealthy people may buy more cars to get available access every day. And it will be inconvenient for people who need drive cars in some emergency situation.

This funding round is the latest move in a year of exponential growth for Perimeter 81. Launched in February 2018, the company has already seen 400% year over year revenue growth, expanding from 180 businesses using Perimeter 81 to 500 in the past eleven months alone.


Hong Kong democrats score landslide victory in local elections - RTRS
by Ross J Burland- Democratic candidates across the city of 7.4 million secured more than half of the 452 district council seats.
- The outcome should be risk-friendly for the immediate term; Eyes on AUD/JPY.
Reuters reported that "Democratic candidates across the city of 7.4 million secured more than half of the 452 district council seats for the first time, against a strongly resourced and mobilized pro-establishment opposition."
- "As of 5:00 a.m. (2100 GMT), pro-democracy candidates had secured a majority with at least 283 seats, compared to about 32 seats for the pro-establishment camp, according to local media estimates. A record 1,104 candidates were vying for 452 seats."
- “The government needs to know that if they don’t answer our demands, we will continue demanding and the protests will not stop,” said a 26-year-old pro-democracy voter who gave her name as Cda."
Update
"Pan-democrats apparently have scored a huge victory in HK district council elections. It's hoped they will expand influence within constitutional framework from now on,stop radical street politics. It's also hoped the elections will be turning point in ending the riots"
- Hu Xijin, the Chief in Editor for the Global Times.
FX implications:
One would presume that this is pro-risk for markets, hopefully giving the protesters a score over the elite, although only time will tell as to whether the lull in troubles leading into the elections will continue or not. President US Trump is on standby with respect to the Honk Kong bill and we are expecting announcements soon – "Trump also made clear his reluctance to sign the Hong Kong Hong Kong Human Rights and Democracy Act, which passed Congress with overwhelming support ," which impinged on US/Chinese relations, "Republican senators responded by insisting that the bill would become law, using a Congressional override of a presidential veto if needed," analysts at Westpac explained. The yen and Aussie are the most correlated currencies to US-China trade disputes making AUD/JPY a compelling technical set-up:
- Chart of the week in Analysis: AUD/JPY at a critical juncture
- AUD/JPY looks for fresh direction to stays above 100-day SMA

Couple want their 4-month-old child reunited with them
by Staff ReporterA couple urged the district administration to take necessary steps to reunite their four-month-old newborn with them who they alleged was taken away by the girl’s parents.
They submitted a petition at the district collectorate on Monday.
The couple Raja and R. Meena, residents of Nainampatti village, got married against the wishes of their parents in 2017. The couple worked at a garments firm in Tiruppur and Meena recently delivered a boy in Tiruppur.
Raja said that post-delivery, Meena became unwell and she was taken for treatment at the Tiruppur Government Hospital.
Better treatment
“For better treatment, she was later referred to the Coimbatore government hospital and I informed her parents regarding Meena’s condition.
They decided to take Meena and newborn to Salem for better treatment at a private hospital here.”
Meena said, “I recovered in a few days.

I was taken back to village and I was locked up in my house.
Later, I managed to escape from the place and returned to my husband in Tiruppur.
Child adoption
When enquired, my parents told that they gave our child in adoption to a family in Chennai.
We have complained with police and Collector.”


Take That America
Robbie
Williams: From the Top of the Pops to the Bottom of the Barrel
and Back Again
By Kurt B. Reighley. Photos by Hamish Brown. Click here for the photographs.
If the
throng of girls Im scrambling past knew what had just
happened, theyd tear me limb from limb--or at least leave
me standing in the streets of Dublin in my boxers. Just minutes
ago, pop sensation Robbie Williams presented me with a special
gift: his pants, simply because the color, bright orange, matched
my hair.
Who could blame these lasses if they set upon me violently?
Theyve huddled in the cold drizzle all day, waiting for a
glimpse of Williams exiting the hotel. Meanwhile, hes been
strutting around in his Calvins solely for my amusement. (If
its any consolation ladies, Ive dreamed of Williams
dropping his trousers for longer than I care to admit.) You say
youve never heard of this guy? Well, if youre not a
big fag, an ardent British-music devotee or a very savvy teenage
girl, theoversight is excusable for a few weeks more--until
Williams officially launches his assault of on America.
In England, Williams has released two number-one albums: the
quintuple-platinum Life Thru A Lens and last years
follow-up, Ive Been Expecting You. (His American
debut, The Ego Has Landed, on Capitol records, culls cuts
from both.) His single Angels ruled the British Top
Ten during the 1997 Christmas season, and MTV Europe crowned him
Best Male Perfomer last year. And thats all since leaving
Take That, the celebrated boy band with whom he sold over two
million albums and racked up eight number-one hits. His split
from the group in 1995 heralded the demise of one of
Europes biggest pop acts.
The extraordinary aspect of his story, however, isnt the
dizzying height to which Williams has climbed. Whats
remarkable is how many times hes fallen on his face,
literally and figuratively, along the way. For one thing, before
the success of Angels resuscitated sales, Life Thru a
Lens had moved barely 40,000 units. He had released three other
singles prior to that, each greeted with an increasingly
lackluster reception, and his consumption of drugs, alcohol, and
food raged unchecked. In photos, he constantly appeared bloated,
over-weight, exhausted.
  Right now, hes flinging pieces of sashimi across
the hotel suite into his buddy Jonathan Wilkes open mouth,
like a trainer feeding a seal. An interview with the 25-year-old
star resemples nothing so closely as hanging with
Winnie-the-Poohs spastic pal Tigger. The singer pauses to
offer me a take-out tin of raw fish, the same one hes been
tappin his cigarette ashes into. Would you like some
salmon? he asks, straight-faced. Its
smoked.
The adrenaline from last nights sold-out gig hasnt
subsided. We did a two-hour show, Williams proclaims.
I didnt want to get offstage.  Yesterdays show
also featured another landmark. I had my first big strop
last night too. Do you know what that means? he asks.  He smirks, dusting off his hands.
Thats a strop. It seems the prop hes
required for a comedy bit hadnt been ready. Ive
never shouted like that before, he says. I even
scared myself. Now that Im playing in arenas and loads of
people like me, Im going to be mean to them.
 Though he possesses a viscious wit, Williams
is exeptionally good natured. At our first, accidental meeting,
he extends his hand and announces, Hi, Im Rob,
in regular-guy fashion, without any prompting from his handlers.
Theres an Everyman quality about him. Taxi drivers in
Dublin all speak highly of him this weekend. Palpable sincerity
underscores Williams enthousiastic delivery, his cocky
disposition offset with exuberence. His hit Let Me
Entertian You captures this ceaseless need to amuse in a
video that showcases him strutting about in Kiss drag. This is
exactly the sort of good old fashioned showbiz pizzazz that
American rock desperately needs today. Shoe-gazing and
being serious and slashing your wrists is all right, he
shrugs, if you like that sort of stuff.
Man or
Party Machine
Williams
didnt make the transition from teen idol to credible artist
smoothly. Extricating himself from contractual ties to Take That
demanded time and money and prohibited him from recording for a
year. Although he needed time to regroup, he couldnt stay
out of the public eye. Id worked nonstop: seven days
a week for six years, he says. It seemed only natural to
continue the breakneck pace. He filled the void with stints as a
TV presenter, talk show guest and a general rabble-rouser.
I said, f*** work, Ill move to London and drink a
lot, he recalls. He became a fixture on the celebrity pop
circuit. In Take That, we werent allowed to go out to
these sort of places, he explains. And to my expense,
a shrinking bank balance and rehab later, I found out why.
Its a tribute to the lads stanima that he maintained
the debaunchery as long as he did. In his concerts nowadays, a
montage of exploding Jack Daniels bottles and humiliating
tabloid headlines flashes onscreen during Man
Machine, which commemorates his downhill slide.
Waking up at 2 oclock in the morning and going out to
start the night for the next day was normal, Williams says.
Hed call a cab, hit the clubs and start shoveling coke up
his nose.
Williamss new record company wasnt amused.
Overexposure was eroding its acquisitions charisma, and
Williams had produced little music. His singing ability
wasnt in question--hes handled lead vocals on two
Take That hits--but songwriting wasnt proving so easy.
I knew that I could write poetry, he insists.
But I also knew that I only knew three chords, and the
combination of those chords cant last forever. Unless
youre the Ramones. or Oasis, he says, appearing
momentarily startled by his own tongue; the Gallagher brothers
are his friends. Meow, he muses, pursing his lips.
Put the knife back in the drawer, Ms. Sharp.
The View
From The Bottom
Its
no coincidence that Williams is kicking off his European tour in
Dublin. This is where he had the epiphany that eventually set him
back on course. Hed come alone, he says, on a sad,
self-destructive mission during the 1996 Christmas
holidays. I got off the ferry and didnt even
unpack--just went straight to the pub, he says. Then
I wandered about aimlessly, drinking Guiness. Through the
haze, the pensive lyrics for Angels took shape. By
praying to be redeemed by a higher power, Williams discovered the
key to rescuing himself. I got back and the record company
went--he assumes a very stern tone--Heres a
sheet of people youre going to write with. Pick one!
Mercifully, his shotgun wedding to Guy Chambers (of World Party)
clicked. Their collaborations sparkled with the pop polish of
Williams past, but recast in the indie rock tradition of
Oasis, Blur, and Manic Street Preachers.
Still, Williams recorded his first full-length album in a stupor.
He checked into rehab before the album hit the shelves, then
tackled the promotional trail clean and sober. (These days, the
singer isnt tee-total, but keeps his vices in check.) But
despite a reputation for loving the underdog, the British public
had tired of his antics.
Rejection caught Williams off guard. Hed gone straight from
school to Take Thats protective cocoon of foame. Sales of
his first two singles, though hardly breathtaking, had proved
impressive. Then I released the album and, arcing his
hand sharply, he imitates an airplane plummeting to the ground.
People whod once cooed over his every quip wouldnt
deign the book to him on predawn chat shows.
These days, thanks to the belated triumph of Angels
and the hits that followed--Let Me Entertain You,
Millenium and No Regrets--the shoes
back on teh other foot.
Earning Indie Cred
One attribute thats never failed Williams is his refusal to
play his cards close to his chest. I expose all my
weaknesses, so nobodys got anything on me,he says.
Though hes uttered many unkind remards to his former band
and his ex-manager, Nigel-Martin Smith (inspiration for the
blistering song Karma Killer), hes rarely
recanted.
Currently, the charts are clogged with prefab boy
bands--Backstreet Boys, N Sync, Boyzone--for which Take
That set the standard. Although Williams crosses paths with them
occasionally, members rarely approach him.  Originally, as soon as Id
left, theyd ask me for advice. They stopped queuing
up when he checked into rehab.
Williams moves in different circles now. He performed alongside
Tom Jones at last years Brit Awards. The Pet Shop
Boys Neil Tennant and the Divine Comedys Neil Hannon
sang on his recent smash No Regrets, and the latter
is serving as this tours support act. I have to be
drunk just to speak to (Hannon), because Im so in awe of
his talent, Williams says. But the only person who
questions Williams crediblitynow is himslef. Damon Albarn
from Blur is his neighbor. When their paths cross, Williams
dissolves into a stuttering schoolgirl. Is this person
thinking I am a dick? he worries. The paranoia stems
partially from respect for Albarns songwriting, but the
main culprit is the specter of Williams past.
Theres still that habit built-in reaction :
I. from a boy band, and youre immensibly
credible. During the making of Life Thru A Lens,
Guy Chambers had telephoned Sonya Madan of Echobelly and invited
her to sing on a track. She laughed and hung up on him.
Im not a musician, Williams says. The craft of
composition often feels foreign. I dont pretend to be
Marilyn Manson or Billy Corgan or Noel Gallagher. I dont
have intistic artegrity.
You read that spoonerism right. Williams has dyslexia, which he
lampoons frequesntly. Im going to write a song
called, Just Because You;re Dyslexic Doesnt Mean
Youre Not Thick, he announces. So many people
go, Oooh, can you check the bill out?or Can
somebody spell this for me? Im dyslexic. And because
its the 90s and everybodys PC, its
accepted.
Political correctness puts Williams knickers in aknot,
primarily because its ruined his favorite film franchise.
 On the cover of Ive Been Expecting You,
Williams strokes a cat, one eyebrow cocked in a homage to the
secret agent. Millenium, his first U.S. single,
continues the trend, lifting a riff from You Only Live
Twice for the hook and showcasing the singer with a gaggle
of Bond beauties in the video.
The Bond parallels point toward why this man stands to succeed in
America where other U.K. phenomena have fallen short. Like the
secret angent at his best, Robbie Williams is quintessentially
British in character yet international in appeal. Women want to
be loved by him and men would love to be him.
A few would opt for both.  But hed be very good at it if he
were. By the end of our interview he has: a) extolled the
physical charms of Elvis Presley, short-lived Bond George Lazenby
and even Matt LeBlanc of Friends b) shouted, All
right, Im gay! and Id sleep with Tom
Jones; c) stripped down to his underwear; and d) kissed me
good-bye.
Not surprisingly, Williams combustible character has
confounded some critics in the build-em-up,
knock-em-down U.K. media. Much of the praise he receives is
backhanded. They say that Im humbly
arrogant, he claims. you know Prince Naseem
(Hamed), the boxer? Hes never been beat. He makes
predictions about what round hes gonna knock people out in.
 Sometimes I get accused of the same thing.  If I dont become the
very best entertainer, Im going to fall.
After a decade in training, Robbie Williams is ready to square
off with America. But first, hes going to fetch a change of
pants.

Studies otolith shape variation among fish populations. Otoliths are calcified structures found in the inner ear of teleost fish and their shape has been known to vary among several fish populations and stocks, making them very useful in taxonomy, species identification and to study geographic variations. The package extends previously described software used for otolith shape analysis by allowing the user to automatically extract closed contour outlines from a large number of images, perform smoothing to eliminate pixel noise, choose from conducting either a Fourier or wavelet transform to the outlines and visualize the mean shape. The output of the package are independent Fourier or wavelet coefficients which can be directly imported into a wide range of statistical packages in R. The package might prove useful in studies of any two dimensional objects.

This post is an event report and a quick walk through to a submission that I developed with a group of participants at an Alibaba / Met Office UK hackathon. We are using the A* algorithm with a couple of tweaks to route cargo balloons from London to a number of cities in the UK.
It’s the year 2050. The invention of anti-gravity engines has led to the creation of unmanned balloons that travel the UK, delivering goods. However, unpredictable weather conditions mean that these balloons are often delayed, damaged or even destroyed(!), so we need your help. We’re inviting you to join our contest AND our hackathon to create an algorithm which allows these balloons to get to their route safely and effectively.
In January of this year, the Met Office teamed up with Alibaba Cloud in organising a hackathon at Huckletree Shoreditch. Here is a short video that gives a good impression of the event
The hackathon was organised as a “Future Challenge”, a fictitious scenario for the year 2050. Obviously, drone delivery would be considered so 2020 and completely outdated by then. Instead, people are relying on anti-gravity balloons to deliver goods to cities across the UK via air drop. These anti-gravity balloons are reliable and efficient, but have one major shortcoming: They crash when travelling in areas with high wind speeds. This is where the Met Office comes in. The task was to navigate balloons from origin to destination while avoiding storms by using the Met Office forecasts.
I’ll spare you the full run through of rules, terms, and conditions. You can find them on the competition page. The main facts: - forecast data provides projected wind speed for fields of a grid - forecasts are for hourly intervals - balloons can move up, down, left, right, or stay in place - balloons move one field per 2 minutes - balloons crash when entering a field when the wind speed is ≥15
So the big question is: How do we safely get the balloons from origin to destination while avoiding stormy areas?  It was great to see their enthusiasm for working on this problem!
The data that was provided to us was: 1. the coordinates of cities (origin and destinations) 1. weather data, separated into: * a training set with 7 days of weather forecasts from 10 models plus observations of the actual conditions that manifested on these days * a holdout set with 5 days of weather forecasts
You should still be able to get the data here in case you’d like to have a go yourself. Note that the weather forecasts came in at a rather inconvenient file size of 2 x 800 MB, and download speeds were not that great either.
See the map below for illustration purposes. The map shows gridded forecasts of wind speed for a one hour time slice, as well as city locations (origin in yellow, destinations in red). Weather Forecast
We started by looking at the weather predictions. Our initial plan was to use the first week, for which both forecasts and observations were available, to train a classifier that would identify the likelihood of high wind speeds in a given area at a particular time. This, however, turned out to be a bit of a red herring. The Met Office predictions were so good that averaging them and using a simple threshold of 15 resulted in close to zero false negatives when trying to detect cells with storms.
Lesson learned: Do your EDA properly to check which areas are worth investigating in detail and where you can use a simple ad-hoc solution.
```python import numpy as np import pandas as pd import matplotlib.pyplot as plt import h5py
def convert_forecast(data_cube): # take mean of forecasts arr_world = np.min(data_cube, axis=2) # binarize to storm (1) or safe (0) arr_world = arr_world >= 15 # from boolean to binary arr_world = arr_world.astype(int) # swap axes so x=0, y=1, z=2, day=3 arr_world = np.swapaxes(arr_world,0,2) arr_world = np.swapaxes(arr_world,1,3) arr_world = np.swapaxes(arr_world,2,3)
return(arr_world)
data_cube = np.load(‘../data/5D_test.npy’) # convert forecast to world array forecast = convert_forecast(data_cube) ```
We wanted balloons to take the shortest path from origin to destination without passing into storms. That means storms can be viewed as obstacles in our path search problem, because we would never, ever, want to pass through them, even if that means a massive detour for the balloon. We therefore chose to use an A* path search algorithm. This algorithm finds the shortest path around obstacles in a reasonable amount of time and is quite straight forward to implement.
The basic approach is to start from origin and generate a frontier possible next moves from a list of valid neighbouring fields. Fields with obstacles are excluded, as well as fields that have been visited before. For each field that is part of this frontier we log which field we came from and calculate a heuristic cost of our movement to far. As soon as the destination field becomes part of the frontier, we can recursively follow the trail laid out in our log, back to the origin, to find the shortest path.
In case you would like more details or want to compare A* to other pathfinding algorithms, this page has the best summary of pathfinding algorithms I have seen, including a great section on A* with interactive simulations.
In our case, there is one additional complication: our search is two-dimensional (geographical space with latitude and longitude), but our “obstacles” change over time. My way around that was to make the search three-dimensional, with each movement time step (2 minutes) as a slice in the third dimension.
python
# repeat time slices x30
forecast_stack = np.repeat(forecast, repeats=30, axis=2)
I then forced the search algorithm
to always take a step forward in time by restricting the valid neighbours to
[..., ..., z+1]
. I tried to illustrate this schematically in the diagramm below:
The code for my A* implementation in python using heapq
can be found below.
Note that I allow for neighbours that have the same x and y coordinates. This essentially allows balloons to “hover in place” to wait out unfavourable weather conditions in the area ahead, should that be the most promising course of action.
Another thing to mention is that this approach massively inflates our frontier.
Usually, an advantage of the A* algorithm is that fields that have been visited
before do not need to be considered again. In my approach, field [0,0,0]
is
different from field [0,0,1]
(the same latitude and longitude, but a different
time step). As a result, computation becomes a lot more resource intense, but it
is still feasible to run this on your local machine and in the fast-paced
setting of a hackathon I think that prioritising developer time over computing
time was the right call.
```python import heapq
def heuristic_function(a, b): return (b[0] - a[0]) ** 2 + (b[1] - a[1]) ** 2
def astar_3D(space, origin_xy, destination_xy): # make origin 3D with timeslice 0 origin = origin_xy[0], origin_xy[1], 0 # logs the path came_from = {} # holds the legal next moves in order of priority frontier = [] # define legal moves: # up, down, left, right, stay in place. # no diagonals and always move forward one time step (z) neighbours = [(0,0,1),(0,1,1),(0,-1,1),(1,0,1),(-1,0,1)]
cost_so_far = {origin: 0}
priority = {origin: heuristic_function(origin_xy, destination_xy)}
heapq.heappush(frontier, (priority[origin], origin))
# While there is still options to explore
while frontier:
current = heapq.heappop(frontier)[1]
# if current position is destination,
# break the loop and find the path that lead here
if (current[0], current[1]) == destination_xy:
data = []
while current in came_from:
data.append(current)
current = came_from[current]
return data
for i, j, k in neighbours:
move = current[0] + i, current[1] + j, current[2] + k
# check that move is legal
if ((0 <= move[0] < space.shape[0]) &
(0 <= move[1] < space.shape[1]) &
(0 <= move[2] < space.shape[2])):
if space[move[0], move[1], move[2]] != 1:
new_cost = 1
new_total = cost_so_far[current] + new_cost
if move not in cost_so_far:
cost_so_far[move] = new_total
# calculate total cost
priority[move] = new_total + heuristic_function(move, destination_xy)
# update frontier
heapq.heappush(frontier, (priority[move], move))
# log this move
came_from[move] = current
return 'no solution found :('
cities = pd.read_csv(‘../data/CityData.csv’, header=0) # run algorithm x = astar_3D(space=arr_world_big[:,:,:,0], origin_xy=origin, destination_xy=destination) ```
We have a predicted optimal route now. That’s great, but it would be even
better to visualise these results in a way that allows us to develop some
intuition about how our solution is doing and where we could improve it further.
I thought that an animation of the time slices with the paths generated would
be ideal for this. So I used matplotlib.pyplot
to create an image of each
time slice and then combined them into an animated gif. Output and code below:
You can see that, for this day, the solution for most cities is relatively straight-forward because of low wind speeds in the majority of the area. However, the A* pathfinding algorithm can be seen nicely at work in the later timeslices and the centre-right of the map, where the purple balloon pauses for a timeslice to wait out unfavourable conditions ahead and then winds around patches of high wind speed towards its target.
```python def plot_solution(world, cities, solution, day): timesteps = list(range(0, 540, 30)) solution = solution.loc[solution.day == day,:] # colour map for cities cmap = plt.cm.cool norm = matplotlib.colors.Normalize(vmin=1, vmax=10) # colour map for weather cm = matplotlib.colors.LinearSegmentedColormap.from_list(‘grid’, [(1, 1, 1), (0.5, 0.5, 0.5)], N=2)
for t in timesteps:
timeslice = world[:,:,t]
moves_sofar = solution.loc[solution.z <= t,:]
moves_new = solution.loc[(t <= solution.z) & (solution.z <= t + 30),:]
if len(solution_subset) > 0:
plt.figure(figsize=(5,5))
plt.imshow(timeslice[:,:].T, aspect='equal', cmap = cm)
# plot old moves
for city in moves_sofar.city.unique():
moves_sofar_city = moves_sofar.loc[moves_sofar.city == city,:]
x = moves_sofar_city.x
y = moves_sofar_city.y
z = moves_sofar_city.z
plt.plot(list(x), list(y), linestyle='-', color='black')
# plot new moves
for city in moves_new.city.unique():
moves_new_city = moves_new.loc[moves_new.city == city,:]
x = moves_new_city.x
y = moves_new_city.y
z = moves_new_city.z
plt.plot(list(x), list(y), linestyle='-', color=cmap(norm(city)))
# plot cities
for city,x,y in zip(cities.cid, cities.xid, cities.yid):
if city == 0:
plt.scatter([x-1], [y-1], c='black')
else:
# balloon still en-route?
if city in moves_new.city.unique():
plt.scatter([x-1], [y-1], c=cmap(norm(city)))
else:
plt.scatter([x-1], [y-1], c='black')
# save and display
plt.savefig('img_day' + str(day) + '_timestep_' + str(t) + '.png')
plt.show() ```


Setting up Your Machine
I’d meant to include this with the book, but I couldn’t get things working right on Windows. If you’ve been able to, please post about and I’ll try to replicate and include the instructions here. For those of you on Mac OS or Linux, read on!
MacOS & Linux
It’s likely that your system came installed with a version of Ruby. It’s also likely that it came with a very old version of Ruby. For example, Mac OS X Lion, the latest operating system produced by Apple at the time of this writing, ships with a version of Ruby 1.8.7, built in January of 2010.
While we could install a more recent version, there’s usually a good reason why operating system vendors install specific versions, and updating the system’s version of Ruby could cause unforseen problems. Fortunately, the Ruby Version Manager (RVM for short) is a tool that can fix this. RVM will allow us to setup a completely isolated Ruby environment, outside of the system’s Ruby, with complete control over the gems we install. In fact, we can set up completely different sets of gems, and switch between them.
We’ll walk you through installing RVM, and creating a gemset for the purposes of running some example code that will verify that your environment is working. These will be very explicit instructions, but you should check the RVM website for the latest RVM installation instructions and documentation.
Installing General Development Tools
Before setting up RVM, you’ll need to make sure you have appropriate developer tools installed. It’s likely you have these installed already, especially if you are using Linux. You can do a quick check via:
1 2 |
|
It doesn’t matter where gcc
(the open-source Gnu C Compiler) is installed, just so long as it is. If it’s not, and you are running Linux, consult your distribution’s instructions for installing development tools. If
you are running Mac OS X, you’ll need to install XCode, which should’ve been included with your computer, but is also available as a free download from the Mac App Store.
Installing RVM
Now that you have development tools installed, we need
to install RVM, which is done by executing a remote bash
script.
1
|
|
If you are concerned about blindly executing code from the Internet, you can examine the installation script via
1
|
|
When RVM installs, it will generate a large amount of output. At the very end will be some instructions for configuring RVM in your environment. It should be a command like so:
.bashrc
for RVM 1
|
|
This concatenates some code into your .bash_profile
. If you aren’t using bash
as your prompt, or don’t configure it in .bash_profile
, you’ll need to replace the
>> ~/.bash_profile
with the correct file name.
Once you’ve done this, you need to reload your environment. It’s simplest to exit your current shell and open up a new one. You can check that things are working via:
1 2 |
|
If you do not see the output above, something’s gone wrong and you’ll need to retrace your steps. RVM’s installation instructions will help, and there is additional information on the website for troubleshooting. Next, you’ll need to install a version of Ruby.
Installing Ruby
Now that RVM is installed, we can use it to install any version of Ruby in a way that will not affect our system’s Ruby install. At the time of this writing the latest version of Ruby is 1.9.3, so let’s use that:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
|
The output might not exactly match, but you should see something along these lines. It may take a while, since it first downloads the source code for Ruby 1.9.3, and then builds it (this is why we needed a C compiler installed in the first step). To check that things are working:
1 2 3 |
|
Again, the string might not match exactly, but you should see “1.9.3” in the version string. We’re almost ready. The last thing we need to do is learn about using Gemsets. Since we are using several open-source gems throughout the book, it’s handy to be able to install them in a “sandbox” that allows us to play around with them, but without installing them in our main, global set of gems.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 |
|
As you can see, we created two gemsets, named testing
and testing2
and used rvm gemset use
to switch between them. In doing so, gem
only sees the gems listed in the current gemset. Further, we can see that by installing gli
in one gemset and not the other, RVM also manipulates our PATH
so that the gli
executable is available only in the gemset where gli
is installed.
I would recommend that you use a gemset for following along with the examples in the book. By doing this, if you get into a weird situation where your environment isn’t working, you can clear out your gemset with rvm gemset delete
and start fresh.
Windows
As mentioned, I was unable to get a good Windows install working. At the very least you will need to use the Ruby Installer to get Ruby on your system.
The specific troubles I had were around installing native gems using the DevKit. If you can get everything installed on a Windows 7 box, and execute the examples, please share it. Note that, at this time, Aruba doesn’t work with Windows, however everything else should.

| Name: | What it Does: | Syntax: | Parameters: | Returns | Note: | Example: | Extra Info: | ||||||||||||||||||||||
| Document.querySelectorAll() | Document method: returns a static (not live) NodeList representing a list of the document's elements that match the specified group of selectors. A selector could be a element type followed by a dot and then a class name. | elementList = parentNode.querySelectorAll(selectors); | selectors A DOMString containing one or more selectors to match against. This string must be a valid CSS selector string; if it's not, a SyntaxError exception is thrown |
A non-live NodeList containing one Element object for each element that matches at least one of the specified selectors or an empty NodeList in case of no matches. | Note: If the specified selectors include a CSS pseudo-element, the returned list is always empty. |
|
This method is implemented based on the ParentNode mixin's querySelectorAll() method. | ||||||||||||||||||||||
| Document.getElementById() | �Document method getElementById() returns an Element object representing the element whose id
property matches the specified string. Since
element IDs are required to be unique if specified, they're a useful way to
get access to a specific element quickly. If you need to get access to an element which doesn't have an ID, you can use querySelector() to find the element using any selector. |
const element = document.getElementById("id"); | id The ID of the element to locate. The ID is case-sensitive string which is unique within the document; only one element may have any given ID. |
An Element object describing the DOM element object matching the specified ID, or null if no matching element was found in the document. |
|
Usage
notes The capitalization of "Id" in the name of this method must be correct for the code to function; getElementByID() is not valid and will not work, however natural it may seem. Unlike some other element-lookup methods such as Document.querySelector() and Document.querySelectorAll(), getElementById() is only available as a method of the global document object, and not available as a method on all element objects in the DOM. Because ID values must be unique throughout the entire document, there is no need for "local" versions of the function. |
|||||||||||||||||||||||
| Document.createElement() | In an HTML document, the document.createElement() method creates the HTML element specified by tagName, or an HTMLUnknownElement if tagName isn't recognized. | let element = document.createElement(tagName[, options]); | tagName A string that specifies the type of element to be created. The nodeName of the created element is initialized with the value of tagName. Don't use qualified names (like "html:a") with this method. When called on an HTML document, createElement() converts tagName to lower case before creating the element. In Firefox, Opera, and Chrome, createElement(null) works like createElement("null").���������������������������������������������������������������� ��������������������������������������������������������������������������� options������������������������������������������������� Optional An optional ElementCreationOptions object, containing a single property named is, whose value is the tag name of a custom element previously defined via customElements.define(). See Web component example for more details. |
The new Element. |
|
||||||||||||||||||||||||
| Element.setAttribute() | Sets the value of an attribute on the specified element. If
the attribute already exists, the value is updated;
otherwise a new attribute is added with the specified name and value. To get the current value of an attribute, use getAttribute(); to remove an attribute, call removeAttribute(). |
Element.setAttribute(name, value); | name A DOMString specifying the name of the attribute whose value is to be set. The attribute name is automatically converted to all lower-case when setAttribute() is called on an HTML element in an HTML document. value A DOMString containing the value to assign to the attribute. Any non-string value specified is converted automatically into a string. |
undefined. | �In the example to the
right: �����������������������������������������������The
first call to setAttribute() above shows changing the name attribute's value
to "helloButton". You can see this using your browser's page
inspector (Chrome, Edge, Firefox, Safari). To set the value of a Boolean attribute, such as disabled, you can specify any value. An empty string or the name of the attribute are recommended values. All that matters is that if the attribute is present at all, regardless of its actual value, its value is considered to be true. The absence of the attribute means its value is false. By setting the value of the disabled attribute to the empty string (""), we are setting disabled to true, which results in the button being disabled. |
|
Boolean
attributes are considered to be true if they're present on the element at
all, regardless of their actual value; as a rule, you should specify the
empty string ("") in value (some people use the attribute's name;
this works but is non-standard). See the example below for a practical
demonstration. Since the specified value gets converted into a string, specifying null doesn't necessarily do what you expect. Instead of removing the attribute or setting its value to be null, it instead sets the attribute's value to the string "null". If you wish to remove an attribute, call removeAttribute(). |
||||||||||||||||||||||
| Document.createTextNode() | Creates
a new Text node. This method can be used to escape HTML characters. |
var text =
document.createTextNode(data); text is a Text node. |
data���� ��������������������������������������������������������������is a string containing the data to be put in the text node. | None |
|
||||||||||||||||||||||||
| Node.appendChild() | The
Node.appendChild() method adds a node to the end of the list of children of a
specified parent node. If the given child is a reference to an existing node
in the document, appendChild() moves it from its current position to the new
position (there is no requirement to remove the node from its parent node
before appending it to some other node). This means that a node can't be in two points of the document simultaneously. So if the node already has a parent, the node is first removed, then appended at the new position. The Node.cloneNode() method can be used to make a copy of the node before appending it under the new parent. Note that the copies made with cloneNode will not be automatically kept in sync. If the given child is a DocumentFragment, the entire contents of the DocumentFragment are moved into the child list of the specified parent node. |
element.appendChild(aChild) | aChild The node to append to the given parent node (commonly an element). |
The returned value is the appended child (aChild), except when aChild is a DocumentFragment, in which case the empty DocumentFragment is returned. | The ParentNode.append() method supports multiple arguments and appending strings. |
|
|
||||||||||||||||||||||
| GlobalEventHandlers.onload | The
onload property of the GlobalEventHandlers mixin is an EventHandler that
processes load events on a Window, XMLHttpRequest, <img> element,
etc. The load event fires when a given resource has loaded. |
target.onload = functionRef; | Value functionRef is the handler function to be called when the window�s load event fires. |
Notes The load event fires at the end of the document loading process. At this point, all of the objects in the document are in the DOM, and all the images, scripts, links and sub-frames have finished loading. There are also DOM Events like DOMContentLoaded and DOMFrameContentLoaded (which can be handled using EventTarget.addEventListener()) which are fired after the DOM for the page has been constructed, but do not wait for other resources to finish loading. |
|
window.onload
fires when the document's window is ready for presentation and
document.onload fires when the DOM tree (built from the markup code within
the document) is completed. Ideally, subscribing to DOM-tree events, allows offscreen-manipulations through Javascript, incurring almost no CPU load. Contrarily, window.onload can take a while to fire, when multiple external resources have yet to be requested, parsed and loaded. |

A typical adventure contains many puzzles. Infocom adventures were notoriously difficult to complete; solving every puzzle might require weeks, even months of trial and error.  I hate adventures that just return “You can’t” in response to every attempt I make to solve one of the game’s puzzles. Such a reply is dull and not very helpful. It neglects an important aspect of any computer game; in fact, an essential part of life itself: the player has to learn from his mistakes. It is OK for an adventure to be difficult, even frustratingly difficult. But when the player has the feeling he is not making any progress at all, or when the only way to make progress is a brute-force attack on all verb-noun combinations, then even the most hardened player will lose interest and eventually give up. The least an adventure game should do, is explain why the player’s command cannot be completed: “You can’t do that, because...” This helps to make the virtual world more convincing, the story more credible, and the game more enjoyable.
I already put quite some effort in having the game explain why certain commands are ineffective. Just take a look at the many printf calls in noun.c, inventory.c, location.c, move.c. But as the game is getting increasingly complex, this is becoming quite a burden. I need a more structural way to detect and handle error conditions. That is what we will be working on in this chapter.
Most commands operate on one or more objects, for example:
The first thing to check (after the obvious typos caught by the parser) is for the presence of these objects; failure should result in something like “There is no ... here” or “You don’t see any ...” In this chapter, we will build a generic function that can be used by every command to find out if an object is within reach of the player.
You may think we only need to distinguish two cases: either the object is here, or it is not. But many commands require more gradients than just ‘here’ and ‘not here’. Examples:
It all boils down to the fact that there are different notions of ‘here’:
| distSelf | The object is the player | object == player |
| distHeld | The player is holding the object | object->location == player |
| distHeldContained | The player is holding another object (for example a bag) containing the object | object->location != NULL && object->location->location == player |
| distLocation | The object is the player’s location | object == player->location |
| distHere | The object is present at the player’s location | object->location == player->location |
| distHereContained | Another object (either an actor or a ‘container’), present at the player’s location, is holding (but not hiding) the object | object->location != NULL && object->location->location == player->location |
| distOverthere | The object is a nearby location | getPassage(player->location, object) != NULL |
The first case (object is player) may seem trivial, but it is important nonetheless. For example, the command "examine yourself" should not return "There is no yourself here."
I tried to follow a logical order: nearby things are at the top, further down below they become more distant. We can continue the list, to cover objects that are even further away:
| distNotHere | The object is (or appears to be) not here | |
| distUnknownObject | The parser did not recognize the noun entered | object == NULL |
Notice we have seven different cases of ‘here’, but only one for ‘not here’. This is because typically, the game only needs to provide information about things that can be perceived by the player. If it’s not here, then there’s nothing more to say.
In the leftmost column, I proposed a symbolic name for each case. We will gather these names in an enum named DISTANCE.
| typedef enum { distSelf, distHeld, distHeldContained, distLocation, distHere, distHereContained, distOverthere, distNotHere, distUnknownObject } DISTANCE; |
And in the rightmost column, I proposed a condition for each case to satisfy. With a little reshuffling, we can easily turn this into a function that calculates the ‘distance’ of an object (as seen from the player’s point of view):
| DISTANCE getDistance(OBJECT *from, OBJECT *to) { return to == NULL ? distUnknownObject : to == from ? distSelf : to->location == from ? distHeld : to == from->location ? distLocation : to->location == from->location ? distHere : getPassage(from->location, to) != NULL ? distOverthere : to->location == NULL ? distNotHere : to->location->location == from ? distHeldContained : to->location->location == from->location ? distHereContained : distNotHere; } |
That’s all! We can call this function and do a comparison on its return value. For example, we had the following piece of code in noun.c:
| else if (!(obj == player || obj == player->location || obj->location == player || obj->location == player->location || getPassage(player->location, obj) != NULL || (obj->location != NULL && (obj->location->location == player || obj->location->location == player->location)))) |
We can now replace each sub-condition by an appropriate distance check:
| else if (!(getDistance(player, obj) == distSelf || getDistance(player, obj) == distLocation || getDistance(player, obj) == distHeld || getDistance(player, obj) == distHere || getDistance(player, obj) == distOverthere || getDistance(player, obj) == distHeldContained || getDistance(player, obj) == distHereContained) |
This can be reduced to:
| else if (getDistance(player, obj) >= distNotHere) |
This was just an example to give you an idea of the concept; the actual implementation of noun.c you will find below, looks slightly different.
Time to put things into place. The definitions of enum DISTANCE and function getDistance are added to misc.h and misc.c, since we will be using them in more than one module.
| misc.h |
|---|
|
| misc.c |
|
Explanation:
In function executeGo, we can replace most of the if conditions by a check on distance.
| Sample output |
|---|
|
Welcome to Little Cave Adventure.
You are in an open field.   You see: a gold coin an exit --> get gold You pick up a gold coin. --> give gold There is nobody here to give that to. --> quit Bye! |
| location.h |
|---|
|
| location.c |
|
The same goes for function executeGet.
| inventory.h |
|---|
|
| inventory.c |
|
And finally, we will adjust the constraints in noun.c. I am adding two parameters to function getObject that make it possible to find a match for a specific noun, while at the same time ignore any objects that are considered absent. This will really pay off in the next chapter, where we will introduce different objects having the same tag.
| noun.h |
|---|
|
| noun.c |
|
Explanation:
The other modules (main.c, parsexec.c, move.c, object.c) remain unchanged, you can see them in previous chapters.
In this chapter, the concept of distance was mainly used to choose between different responses the game can give to the user. But the benefits of distance are not reserved to the output side; it can be used equally well to make improvements on the input side.
