Maze dry pigment on jute 56 x 58 inches 1995
The idea for the series "Games of Disquiet" was drawn from the experience of witnessing the grave illness of my son, who was diagnosed with Hodgkin's disease. I realized, not for the first time, that life is a game in which the rules are unfathomable. Life plays with you, cat and mouse. The "game" seemed the right motif to express that sentiment.
Cancer teaches you about life, but, whatever the outcome, you are scorched in the process.
Journey into the Whirlwind dry pigment on jute 60 x 62 inches 1995
Players: One through four.
To play: Begin at top left, throw dice, wind your way through the 52 stations (weeks of the year), passing red zones (danger), green zones (safety), gray zones (neutral territory). Encounter figures "This, for example, is for protection," "Doctor who fits the bill," "In which boats go at great speed." Game ends at lower left with figure "Person with burning desires." Along the way, pick up cards with riddles of varying difficulty, penalties, and bonuses.

Are there cases where error and mistake are not interchangeable?

In statistics, an error is the amount that a measurement deviates from the 'true' value. Even if no mistakes are made in measuring (that is, all the right methods are used, and used correctly), there might still be error due to limited accuracy of the measurement tools, random fluctuations in the system under consideration, etc. The words are clearly not interchangeable in this context.
One case where they are not interchangeable is in computing where we write error message but not mistake message.
Generally speaking however, error is more formal than mistake. In technical contexts, a mistake happens because of human action, judgement, opinion or decision, while error has no such connotation and can be interpreted more broadly.
Even outside of computing, mistake generally aligns the error as the fault of the person who caused it, while error means it wouldn't have mattered who was involved — it was likely to happen regardless.
In the context of computer programming, mistakes are made by human beings making decisions, but errors can be caused by all kinds of faults, not just decision-making faults. For example, a file can be full of formatting errors, but those errors wouldn't constitute mistakes in the computer context unless a person had typed in the file by hand.
They are not interchangeable in idioms such as in error, trial and error, or error of one's ways.
I must say (though Jasper Loy beat me to it) that computer terminology seems to be more intolerant of replacing error with mistake. A fatal mistake, for instance, is not the same thing as the programming term fatal error.
Also from a baseball context, an error is when someone gets on base due to a defensive miscue. The play is always called an error on a scorecard.
Mistake is a subset of error. In simple terms, a mistake is always an error, but an error is not necessarily a mistake.
Examples might include:
Most of them, I would have thought.
I was taught that an error is when you've analysed the situation, arrived at a response - and it was wrong. (Stroking a lion won't make it calm down)
A mistake is something you unintentionally do. (E.g. forgetting to load the gun before shooting the lion)
Or, less dramatically: an error is the miscalculation due to using sin(x) instead of cos(x), whereas a mistake is forgetting to put in the decimal point in the answer.
One is in the expression error of your ways.
In my opinion;
An error is a problem with execution (you did it wrong)
Where as a mistake is a problem in leadership (you shouldn't have done it in the first place)
In most sense possible, "error" is more on a technical perspective, that is deviating unacceptably from the expected result. On the other hand, "mistake" is more on the non-technical side such as matters that concern morality, ethics or being not in the list of possible answers.

This question already has an answer here:
I've seen an example of how to sign using RSA. Besides the signing itself (s = m^d mod n) it also hashes and adds an IV.
Why is that needed?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
A second reason that a hash is usually present in RSA signature schemes (apart from being able to sign long messages) is to prevent existential forgery attacks. These look like this:
With a hash, the signature checking equation is $H(m) \equiv s^e \mod n$ instead of $m \equiv s^e \mod n$, and this does not allow to create a message $m$ fitting to an arbitrary signature $s$ (assuming the hash function is preimage-resistant). Beware however that it is remains possible to create working $(m,s)$ pairs given the capability to obtain the signatures $s_j$ of chosen messages $m_j\ne m$, using an attack devised by Desmedt and Odlyzko (see section 3 of this paper).
(The padding scheme normally present in signatures serves the same purpose, and is designed to also resist chosen-messages attacks.)
Signing a hash is cheaper than signing the whole document. RSA is relatively costly, and, as long as the hash function is not weak, there isn't any practical difference in security between signing the whole plaintext and signing its hash, because the hash uniquely identifies the plaintext.
Wikipedia says:
Salts add an additional level of security.
All your passwords are hashed and saved in your database using some algorithm or the other. This hash is generated the way and is uniform for all your users (assuming they all have the same password). By using a salt you will basically be giving different users with the same password different hashes.
And that means that if the attacker figures out how to get your plaintext password by creating a rainbow table. He wont just magically have everyone elses password as well. He's goign to have to generate a rainbow table for every user individually.
Note: I am no expert. But I did take a class on security once and that's what I remember from it. Hopefully this answers your que

Aluminum Bomber Seats - Sitting NicelyWritten by on October 1, 2009 Making A Pair Of Aluminum Seats
I wanted a pair of aluminum bomber-style seats for my latest project and decided that I would have a go at making them myself. Most of the bomber seat magazine articles I found were on the complicated side, and involved hundreds of rivets. But reading the articles did give me some idea of how they were made and their dimensions. Each builder seemed to have his own ideas about sloping the back and making the mounting points tip. In the end, it seemed to be down to trial and error and individual taste.
I needed to have a set of very low runners and an adjustable system to tilt the seat back to get comfortable and give some support to the backs of the thighs (very important if you're driving long distances). The car I was building didn't have very much width. I found a runner system at DAX Cobras that was ideal.
I consulted Steve Jest, a good friend who works at Competition Fabrications, owned by Nick Parravani, on how to make the back all in one piece and how to form the base.
My wife, June, and I bought some large flexible card stock from an art warehouse to build a prototype seat; if we liked it we would then use these as patterns for cutting out the aluminum. We looked at a few designs and then tried to interpret them onto paper. We worked out the seat length and width based on the space we had in the car and the maximum height we had. It would be a disaster to build seats that would not fit in the car, or that you couldn't get your bottom into.
Thanks to some help from Steve Jest and the use of Nick Parravani's heavy punching and rolling gear. I now have a couple of aluminum seats that should provide miles of comfortable cruising.
More Photos From This Article View Slideshow
I started by making a card pattern. The sides and back were one-piece and the base was shaped to fit. We taped the two side parts where it needed to fit around the base. After cutting out the sides, we made a card wedge to give it more tilt in the back, about 5 degrees. We then mounted it all on a flat piece of wood and made the front higher than the back to find out whether it was too tall or too narrow to fit the space we had available.I then transferred the pattern for the base of the seat to some MDF board to make the bucks to form the seat bottom. The buck required two pieces, one the size of the seat base and one slightly smaller. The edges of the smaller board were smoothed and chamfered with some 80-grit sandpaper. I then laid out the base pattern on the aluminum sheet and cut around the pattern leaving an extra 3/4 inch to fold over the buck. I sandwiched the aluminum between the two MDF bucks and C-clamped the two together as tight as I could (this is important so that nothing moves on the next stage). I left the front edge with no C-clamps to fold over first.After I had knocked over the front edge I moved a couple of the clamps and worked my way around. I used a rubber hammer on the straight parts, so as not to mark the aluminum too much. I used a flat body-working hammer on the rounded corners. You will have to work at these corners, as the metal tends to stack up.Once I had worked my way around the aluminum and was happy with it, I released the clamps and finished off the edge with a hammer and a dolly. This dolly with a curved portion was very useful for the round corners.Here's the basic seat bottom; more work with a hammer and dolly will come when bringing the two aluminum parts together.Next I laid out the card pattern on the aluminum sheet that Steve had roughly cut out for me. I traced around the edge and then cut it out.Steve helped punch some holes into the seat back and base, which required some heavy equipment. He started by finding the center and working from that. He worked with a pair of calipers to mark the four-hole pattern at the bottom of the back and at the top. Steve drilled pilot holes as location points and then punched the holes using this heavy-duty hole punch tool. The punch left flat holes, but I wanted beveled edges so I de-burred the holes while Steve set up the next stage.We had to roll the curve in the sides before we finished the holes. If you're not lucky enough to have a set of rollers, you could do this with a gas bottle or anything having the right radius.
We then moved onto finishing the holes in the backs and the bases. This is the die that beveled the holes.The seat back was placed in this big hand-driven punch and cranked down until we had the bevel we wanted.I marked the rivet holes 1 1/4 inches apart and drilled them using a small air-powered drill as the two parts were held in place with clamps and skin pins. This took some time as there were approximately 65 rivets in each seat. You can see the backside of the bevels here.I added a raised piece along the front of the seat to stop the cushion from working forward while driving. I played with some card stock to see if it would fit and determine the best way to fold it.I transferred the fold lines to some more aluminum sheet and cut it out with this handy vice cutter, making sure that the marks from the roller were on the piece of aluminum I was not going to use, also making sure that the protection plastic was on the side that was to be visible on the seat.The end pieces were cut with shears before I made the first fold that was to go on the inside of the seat. I couldn't do the next fold in the same position as the fold mark was too far from the clamp.Ron Covell look away. I had to put that fold into the back of the metal brake, lay it on the ground, and fold it with the aid of a large piece of wood and a big hammer.I then squeezed the fold in the mouth with extended bolts to achieve a roll over, and took a measurement at the end of the squeeze to make sure that both rails were the same thickness.
This is the very low seat runner from DAX Cobra. It is about the right size for the seat base. I cut off the rear tube posts and worked with the three holes in the front mount.I cut out four side plates, two for each seat, and four squares to weld to the back end cross-box section. This is the rear pivot point. Up front I drilled three holes corresponding to the three holes in the front mounting point, so the tilt of the seat can be manually adjusted in 5 degrees increments from 5 to15 degrees. In the photo they're set to 10 degrees.I laid the runners on to the aluminum seat, centered the seat base and made a paper pattern that went to the side edge of the seat base. I cut four plates to sit on top of each of the adjusting plates.Steve and I then set about riveting the three aluminum parts into a complete seat. We started by deburing all the holes. Steve riveted the back to the base first, then riveted the cushion bar to the front of the seat.Steve then scored a line in the aluminum, all the way around the edge of the seat. This will take the wire insert. He then started to fold over the aluminum with a hammer and dolly to take the 4mm wire.Once he had worked up the edge he shaped the wire to the edge and worked his way around the full length of the edge of the seat.This is a time-consuming job and takes skill and practice to get it right, but it makes the seat stronger. We will take out the hammer marks with various grades of abrasive paper, just as you would in doing bodywork.
I made eight 3/4-inch bosses and tapped them for the 8.5mm stainless bolts-then welded them to the underside of the seat mounting plate. This will make the removal of the seat bolts much easier than having to get under the set with a wrench when I want to adjust the seating angle.If this all looks like more work than you want to tackle, but you still want to run some custom aluminum bomber-style seats in your rod, you have another option. Jamey "HandMade" Jordan just announced the launch of his new custom interior company offering a full line of "HandMade" hot rod interior products. HandMade Seat Co. offers new bomber-style seats in many styles.If you want to depart from the standard designs, the company can hand-build a one-off custom set to your exact specifications; your unique design will never be rebuilt or sold to another customer, making your custom seats truly unique.

I am interested in clearing up a confusion of mine. I will try to make my question as clear as I can but I apologize in advance if this is not the case.
Given a unitary group of some unital involutive algebra, $U(A) =$ {$u \in A| uu^* = u^*u = I $},
I can define the adjoint action (and right action shortly) of u as $(Ad u)\xi:=u\xi u^*$, Where $\xi \in H$, the Hilbert space on which I am representing the algebra $A$.
Define right action on elements of the hilbert space using Connes Real Structure operator J. $\xi u^* = JuJ^*\xi$. At the level of the algebra the adjoint is then given as $(ad B)\xi:= B\xi - \xi B$.
My Question: How does this generalize in the case where the algebra A is non-associative and H is a general 'bimodule' over A? is conjugation always well defined?
For example. Say I am interested in the group G2 which is generated by the derivation algebra of the octonions (ie it is the automorphism group of the octonions). I can write out the root diagram for G2 so I know there should be an adjoint representation. The octonions O however are are not-associative. As further example if I take A = H = O, how is the adjoint action and conjugation defined (explicitly)?
I imagine there is a very simple answer to this question. Any direct help you could offer or an appropriate reference would be greatly appreciated.

Child Support: What's Fair?
Don't Miss a Beat: Taking All Your Expenses into Account
If your child is a toddler, it's difficult to think about what college will cost or who will pay for it years down the road. If a judge is going to try your case and you have young children, you'll probably have to return to court when the child is a junior or senior in high school to have the judge address the issue of who will pay for college. If you want to settle all the issues now, however, a provision that often works is this: you and your spouse simply agree now to pay half of what it would cost to send your child to the most appropriate school in your state's college system. Any excess amounts (say your child gets into Harvard) will be paid by the parent or parents who can afford it. This way, both parents have a minimum obligation.
What about the First Communion, Bar Mitzvah, the Sweet Sixteen party, the first car? If you negotiate an agreement, anything goes. If your case goes to court, judges may or may not address those types of expenses.
If you want to be ready for anything, you'll want to figure some of the following expenses into your agreement now:
Wait a minute, you might be thinking. If all those items are extras, what am I paying child support for? Answer: food, shelter, clothing, telephone, utilities, and so on. Of course, depending on the amount of child support you are paying, your spouse may use some of the support for these extras.
Be careful, though. Anything you sign might come back to haunt you. Harvey, for instance, felt so guilty about leaving his wife, Jessie, that he agreed in writing to pay for each of their four daughters' weddings at the Waldorf-Astoria or someplace comparable. The daughters were only teenagers at the time. Unfortunately, Harvey's business took a turn for the worse. Although he could not afford the expensive weddings, he was obligated to pay for them. He went into debt to do so.
If you have a breakdown in negotiations, you can fall back on your state's child support guidelines, which really should be the floor for any child support award. Remember, that's the base level, and anything beyond is extra. Don't be afraid to seek help from your lawyers or a mediator.

This sounds like it might do the trick, unless the little bastard go nuts and flings his body over the top of it and lands in your lap while you're doing 75 on the freeway.
@vallejokid: I hear ya. remember a dog is like a child. secure that bastard or slow down, please :)
For the dogs that won't be contained by this, there are also harnesses that attach to the seat belt buckle. Not only does it keep them out of your lap, it also ensures they don't get hurt in the event of sudden braking.

Noob: Using Custom User Extensions
Hi all. VERY new to Sencha and Architect, just downloaded it yesterday actually. I need to utilize an iFrame in the app I am attempting to build. So in searching the forums I located this post I need to use this within a Architect project I'm using currently.
Unfortunately, being new, I have no clue what so ever as to how to implement a custom user extension. And I have been looking for a tutorial or explanation for over an hour.
Could someone please explain what I need to do to implement the SimpleIFrame UX or point me to some tutorial of documentation as to how to accomplish this?
Time is def. of the essence. So pretty pretty please.

You could just add an empty container to the view, and edit the html property (or call "theContainer".setHtml("iframe html")).
If you wanted to replicate having a standalone IframeComponent, you could create a new View and do a linked instance to the parent view. A linked instance just involves dragging the child to the parent in the Views menu. You would add all of the relevant functions to that view (such as updateHtml and reload). If you give the linked instance an itemId, you can easily get it with this.down("#itemId"), and call methods on it ( this.down("#itemId").updateHtml())

Rated 5 out of 5Â by Scrappy Keeps em up! I'm not diabetic but these socks are great for staying up and not cutting off your circulation Would recommend them highly! March 30, 2016
Rated 5 out of 5Â by Annie30 A lucky find It was impossible to find seamless socks until I ran across yours. They are damp when I take them off, but my feet are dry. They shrink a tad when washed, but can be pulled out when putting them on. I would suggest washing them in warm or cold water. January 21, 2016
Rated 2 out of 5Â by Joe From Non-seamless toe Unlike true diabetic socks available most places, the toe seam on these does stick up and is a bit irritating. June 6, 2015
Rated 5 out of 5Â by Smartby very Comfortable They don't constrict your foot and keep it cool. April 13, 2015
Rated 5 out of 5Â by Channing comfy socks These are soft and great for my oversized ankles, no gripping on the ankle/calf but they stay up. February 15, 2015
Rated 5 out of 5Â by Jansherbs Great socks Nice loose top, easy to get over my sometimes uncooperative toes. But still fit nice and snug with no droopiness. Really like them. February 12, 2015
Rated 5 out of 5Â by orangepoppy Fantastic socks I've had a difficult time lately finding women's crew socks with seamless toes. I'm so glad I found these. They are soft and stretchy and incredibly comfortable. The fit is true to size. March 25, 2014
Rated 5 out of 5Â by Sharissma Worth the Investment Recently, I have been diagnosed with sesamoiditis (caused by repetitive movement as one does in dancing or other athletic activities) and mild arthritis in my feet. I needed socks that were in no way restrictive in the toe box--plus be forgiving enough to not "choke" my leg as most socks do to stay in place. These socks are attractive enough to wear with dress dance pants. I am very pleased with this investment. February 4, 2014

occurs when part of a tissue or internal organ bulges through an abnormal opening in the structures normally containing it. This can happen through a rupture, tear, or weakness in the structure. Most often, this bulge is caused by abdominal tissue that has protruded through the wall of muscle and tendon that surrounds the abdomen.
We tend to think of hernias as being the result of lifting very heavy objects. In fact, they can have any number of causes, such as sports activities, overexertion, coughing, or a natural weakness in the abdominal wall that is present at birth.
Hernias can occur in both men and women of all ages, as well as in children. However, hernias tend to be much more common in men, occurring most often in the groin area where the abdominal folds meet the thighs. These are known as
inguinal hernias. This is due in part by the normal descent of the testicles into the scrotum. This creates an unsupported area in the groin where abdominal tissue can protrude.
Women may be more prone to develop hernias at the top of the thigh (the femoral area), very often resulting from the strain of pregnancy and childbirth.
Children are most susceptible to inguinal hernias, with the large majority of these occurring in boys. Infants are also susceptible to umbilical hernias. These generally appear as a protrusion in the naval area. Umbilical hernias in infants tend to be less troublesome than other types of hernias, since they tend to heal without any treatment by the time the child is three or four.
Generally, you will notice a small lump somewhere in the groin or abdominal area. Many hernias are reducible; that is, you can push the tissue gently back into its normal place. If you notice a bulge that does not resolve, or you develop pain at the site, you should seek medical treatment.
If left unattended, the protrusion through the hole or gap can cause increasing amounts of pain, as more of the abdominal tissue pushes through the gap. As long as the hernia is reducible, it is not considered dangerous, but it can still put pressure on the surrounding tissue. A non-reducible hernia can become life-threatening, though, if a part of the bulging tissue becomes trapped and circulation is cut off to the tissue.
Unfortunately, no. With the exception of umbilical hernias in infants, hernias will not go away on their own. It can take months or even years to worsen. If you suspect that you or your child has a hernia, it should be checked by a doctor because of the possible danger of strangulation.
In the short term, reducing strenuous physical activity, losing weight, and/or wearing a truss can lessen the discomfort caused by a hernia. Ultimately, the only way to fix a hernia is with surgery.
Open Hernia Surgery
Open hernia surgery
is performed by making an incision over the site of the hernia. The part of the intestine or other tissue bulging through is then placed back into the abdominal cavity. Finally, the abdominal wall is repaired by stitching the surrounding muscle together.
Open Mesh Surgery
This hernia surgery uses a mesh plug. Here, a small incision is made at the hernia site. The bulging tissue is then returned to the abdominal cavity. The repair of this area is completed by using sterile mesh material to strengthen and repair the weak area.
Laparoscopic Surgery
During laparoscopic surgery, a surgeon inserts small instruments, including a tiny video camera, through small holes made in the abdominal wall. The doctor performs the surgery while viewing the hernia on a TV monitor.
Hernias can be successfully treated. If you notice an bulge in your skin, make an appointment with your doctor for an exam.

You don't have to live across the street to see the rowdiness of the Derby crowd. On Montana Avenue, about a mile away from Churchill Downs, Billy Duckett has observed just as much, if not more, hoopla than those at the track.
"I'd say about 5 a.m. people start arriving (to park on Montana)," he said. "I saw a guy completely nude; drunk as can be. That was after the Derby coming back. He was complaining he lost all his money and he figured, I lost all my money, I might as well lose all my clothes."
Since 1993, Duckett has lived in his home on Montana, where he's seen and heard it all on Derby day. He rarely attends Louisville's largest event, though he worked the track one year with Brantley Security.
Most of the time, on the first Saturday in May, he and his neighbors fire up the grill and throw a cookout in Duckett's front yard. This way, they save on the cost of track admission and the gambling that's likely to ensue. But, staying home for Derby isn't all that bad. After all there's free entertainment showing on the street, which luckily continues throughout the day, since Duckett and his friends won't be driving anywhere until the Derby has concluded.
"Make sure you save up vacation days up for Oaks and Derby because you ain't going nowhere," said Duckett. "When I had my job … and I would drive to work on Oaks it would take me like three hours just to get from here to, say UofL. That's how bad traffic is … and it's chaos."

The King of the Accidental Phone Call
PORT ST. LUCIE, Fla.—During their disappointing 2012 season, the Jets became known for the butt fumble, caused by quarterback Mark Sanchez's unfortunate collision with teammate Brandon Moore's rear end. Across town, the Mets are countering with a derrière distinction of their own: the butt dialer.
That would be Jay Horwitz, the team's longtime director of media relations. Several times per week, and sometimes several times per day, Horwitz accidentally calls a current or former member of the organization. He has mistakenly awakened team executives at 4 a.m., roused coaches late at night and left former Mets around the league puzzled by missed calls from him.
Horwitz, 67, may be the Cal Ripken Jr. of public-relations men, hardly ever taking a day off. But he is the Barry Bonds of butt dialers, putting up staggering numbers and shattering all records. By now, his career butt dials number in the thousands.
"I swear to God, I don't know how I do it," Horwitz said. "I'm not real mechanical."
Like most butt dials, the ones from Horwitz's phone are caused when it shifts in the pocket of his pants. It usually happens when he's walking or sitting. For whatever reason, he refuses to lock his BlackBerry.
As one of Major League Baseball's longest-tenured employees—he has been on the job since 1980—Horwitz also has a massive contacts list. He estimates there are more than 1,000 numbers stored in his phone. How this happens is a mystery to him, but more often than not, the people he butt-dials are the ones he rarely, if ever, intentionally calls.
"It's so strange because there is no rhyme or reason to who gets called," said outfielder Mike Baxter, the recipient of a 4 a.m. Horwitz butt dial last winter. "He just calls random people."
Even when they're on the field, players aren't safe from the butt dialer. First baseman Ike Davis said he's received more than 100 butt dials from Horwitz, but none confused him more than the one he received during a game.
"When I got back to my locker, I checked my phone and the missed call was from 8:10 p.m.," Davis said. "I'm like, why would he call me at that time? I'm at first base. He sees me at first base."
Players try to seek refuge during the off-season, but the butt dialer finds them. Ex-Met Jason Bay learned that the hard way a few winters ago. "I called him back right away and said, 'What's going on?'" Bay said. "He said, 'What do you mean what's going on?'"
Players have tried fleeing to other teams, but wherever they go, the butt dialer follows them. Ramon Ramirez, a forgettable Mets relief pitcher in 2012, was in spring training with the San Francisco Giants last month when the butt dialer struck.
"I was like, 'Who is this?'" Ramirez said. "I called back, but he didn't answer." A month later, Ramirez is still perplexed by the whole episode. "I don't know why he was calling me."
During a 2010 game against the Rockies in Denver, Horwitz accidentally called ex-Met Livan Hernandez from the Coors Field press box. Hernandez, who was then pitching for the Nationals, returned the call from his locker in Washington a short while later. The ensuing conversation played out like an Abbott and Costello skit.
"You called me?"
"You called me."
To this day, Horwitz accidentally calls Hernandez once a month, for reasons unknown to both men.
Players have even tried escaping to other countries, but the butt dialer has no regard for international borders. Nelson Figueroa was in the Dominican Republic pitching in a winter league recently when the butt dialer struck. It had been three years since Figueroa pitched for the Mets and nearly two years since he last appeared in the majors.
He wondered: Were the Mets interested in bringing him back, at long last? Alas, the only interested party was Horwitz's backside. "His butt's got a mind of its own," Figueroa said.
It isn't as if Horwitz isn't adept at using new technology. He recently joined Twitter. Through his account (@Jay_HorwitzPR), he dispenses vital communiqués about the Mets directly to fans.
For example, just before the start of spring training, he tweeted a photo of himself shirtless in a swimming pool, buoyed by a tube and a pair of floaties, with goggles over his eyes and a snorkel lodged in his mouth. Other tweets have included such updates as "Hy" and "Congrats to $." On March 2, he simply tweeted the letter O.
Still, for all his social media savvy, mastering the BlackBerry has proved difficult for him.
A few years ago, while doubling as the Mets' assistant traveling secretary, Horwitz would often try to email players' flight itineraries to an administrative assistant in the general manager's office. The assistant was a woman named Dianne, but when Horwitz typed in the D, he would inadvertently email third baseman David Wright instead.
Wright was too polite to tell Horwitz, so he became a sort of liaison between Horwitz and the woman. "I would just forward the emails to her and say, 'Hey, here's another one from Jay,'" Wright said. "The whole thing's been going on for years. People are just now starting to learn about how, uh, different he is."
For someone who must remain in constant contact with Mets players and executives, the butt dialing has complicated things a bit. Many players now refuse to answer Horwitz's calls unless he sends a text message saying it is really him.
Horwitz was explaining all of this at a picnic table outside Tradition Field on Saturday when his assistant, Ethan Wilson, called. "Did I do it again?" he said. "This is Ethan. I wonder if I butt dialed Ethan."
Horwitz pressed the BlackBerry to his ear.
"Yes, sir, Ethan. Ethan. Ethan?"

I think this would be interesting to see what the growth rates are like for new languages (like scala). These graphs could be used as a demonstration that a particular language is gaining traction for example.
EDIT: yes, I know that I could get this myself from the data dump but it seems like a useful stat to me and one that people would use. Hence the suggestion

I want to make a document with two columns, with each column separate. In other words, I have two separate columns in which I can type, without text flowing from one column to another. My desired use for this is to create 'Questions' on the left column and 'Answers' on the the right column. If there was also a way to align the questions with the corresponding answers, that would be great.
migrated from stackoverflow.com Nov 5 '11 at 23:39
This question came from our site for professional and enthusiast programmers.
Parcolumns should work, but you need to wrap each question and answer in an environment to get good spacing:
I've recently run across the paracol package on CTAN. It has some very nice features for synchronizing items in the columns. Here's a working example:
An ugly solution could also be the following:
It does the wrapping because I set the max width of each column, and the alignment because, well, it's a table.
Nor sure if I have completely grasped exactly what you need to do...
If you do not need continuous flow of related text over page boundaries, and are using an editor like TeXworks TeX User Group TeXworks Editor ( Development version ) or similar that lets you work with the pdf previewer (Crtl Click in editor text or pdf)—I've use minipage environments for things like that in the past.
It helps also by keeping the distinct text segments positionally related to each other, and the areas can even be positioned, and of different widths.
There are also minipage options available.

How does Koth of the Hammer's plus one ability work when it ends right after you use it and the Mountain turned into a creature has summoning sickness (part of the rulings on Gatherer)?
Sign up
- Anybody can ask a question

I think you've misunderstood the ruling:
If the mountain has been under your control since before the beginning of this turn, it does not have "summoning sickness". It's only unable to tap and attack if it's a mountain that you played this turn.
Whether it has summoning sickness or not depends on how long you have controlled the mountain. How long it has been a creature doesn't matter whatsoever.
If you have controlled the mountain since the beginning of your most recent turn, it doesn't have summoning sickness. So you're fine if you played the Mountain on a previous turn.
If you haven't controlled the mountain since the beginning of your most recent turn, it has summoning sickness. If it's a creature, it can't attack, and you can't use its activated abilities with the tap symbol ({T}) or the untap symbol ({Q}) in its cost. (This means you wouldn't be able to use its native mana-producing ability.)
If we set aside the creature aspect, let's not forget that it becomes untapped. The fact that it's still a mountain means you can tap it for mana again. (If you played the mountain this turn, then it would have summoning sickness and thus be uneligible to tap for mana, since it is an activated ability. But the likelihood of having only one mountain in a Koth deck is unlikely, and you'd clearly pick one that didn't have summoning sickness.) Red doesn't get much for acceleration, so that's pretty big. Even Garruk Wildspeaker in green only untapped two forests. Or, if you have the Koth emblem, you can tap it to do one damage again.
Considering the creature aspect, as long as you controlled the mountain from the beginning of your turn, it's not impacted by summoning sickness. Even if it was, if there was a color to give something haste, it would be red.
It has 4 toughness so that it doesn't immediately die to a lightning bolt (which was in standard at the time). Considering how weak red creatures typically are, having a 4/4 mountain out will do wonders for an Overwhelming Stampede in a red/green deck as another consideration for it even if it did have summoning sickness.
Edit: sandbox testing. Circle of Protection: Green
The mountain would NOT have summoning sickness period because it specifically states that it becomes a 4/4 red elemental creature until end of turn. It's still a land. Therefor the mountain can't be a creature before that turn or after that turn. Also seeing as how it is still a land It doesn't have summoning sickness. Lands don't have summoning sickness. So you can still tap it for mana or attack. And if you activated his +1 on an opponents turn you can use it to block or tap to use the mana for an instant.

I am trying to better evaluate my user's engagement and came across a feature of Google Analytics that I didn't know about, Weighted Sort. This is supposed to sort by bounce rate and also time on page, however it appears unselectable in my GA account . Can anyone verify that it is no longer offered? Or do I need to configure it somewhere else? I couldn't find any reference online to this feature being disabled in the new version of Analytics
Weighted sort is intended to filter outlier data from the grid view - for example, if you had the following pages (sorted by Bounce Rate) it's obvious that you'll want to pay more attention to items #3 and #5 over the others, even though a descending bounce rate sort would place the low-traffic pages at the top:
From the Weighted Sort documentation at Google Analytics Help:
With the Bounce Rate column selected, you can switch to Weighted Sort to get a list more like this:
Update: ... and, although it's not listed at Google's help center, you will also need to disable any Advanced Segments you may be using to filter data in order to enable this feature.
You need to sort the data by Bounce rate to enable the greyed out "Wighted sort" By default it is sorted by pageviews.
You need to create a custom report firstly with less columns and have pageviews column next to bounce rate column.

Want to get the data out of http://wiki.openstreetmap.org/wiki/Planet.osm
UPDATE: i just come back from the site http://wiki.openstreetmap.org/wiki/Planet.osm
which has got some files that belong to the openstreetmap-Project. i downloaded a similar file that is derived from a German Mirrorsite - this one here:
i downloaded the file called germany.osm,bz2
according to this instruction
type bzip2 -d planet.osm.bz2; or your OS may support double-click unpacking. See Wikipedia's list of compression programs.
i did the following - but without success-,
martin@linux-wyee:~/poi_abzug/geofabrik> bzip2 -d germany.osm,bz2;
bzip2: Can't open input file germany.osm,bz2: No such file or directory.
why - can anybody explain why i did not succeed?
end of update;
further questions: Is this a XML-File ?
BTW; i only need the data for the Pois in Germany: can i use this file here - http://ftp5.gwdg.de/pub/misc/openstreetmap/
As this might be of general interest i think that many users can benefit from an answer to this question.
So my question is: How to tread the above mentioned dataset - how to read it - on a OpenSuse-Linux-machine!? Should i do it in the terminal?
Note - i want to store all in a csv file - and i look for all the restaurants... What is the easiest way to do this!?
As i am a newbie - thx for your patience!

Common cold
Redirected from Cold
this wiki
The common cold, also known as acute nasopharyngitis, was a viral Human illness of the upper respiratory system that had existed at least since Earth's Stone Age. The primary symptoms of the illness included a sore throat, coughing, and either a stuffed or runny nose. The virus was contagious, and could be spread by both direct contact and droplet infection.
In 2151, Malcolm Reed exclaimed that Humans could travel past light speed, yet still could not cure the common cold. Phlox replied that there was no cure or treatment for the illness except for methods similar to those used in the 20th century. (ENT: "Sleeping Dogs") Jonathan Archer once stated that "if the Vulcans had their way they'd blame micro-singularities for the common cold." (ENT: "Shuttlepod One")
Dr. McCoy noted that modern medicine was still searching for a cure for the common cold in the 23rd century. (TOS: "Plato's Stepchildren") McCoy found a number of promising biological candidates on Omega IV that might lead to a viable cure. (TOS: "The Omega Glory") Scotty also mentioned that the common cold was yet uncured. (TOS: "The Lights of Zetar")
By the mid-24th century, the common cold was apparently cured, though earlier in the century it still existed. (TNG: "The Battle", "Datalore", "Ensign Ro")
On stardate 44723.5 Geordi La Forge experienced headaches, caused by the common cold. (TNG: "Cause and Effect")
Tom Paris once told The Doctor that when he was nine years old, he had a cold. His childhood doctor, Dr. Brown who still made house calls, "whipped up a pot of garlic soup and brought it over himself." (VOY: "Cathexis")

I find myself talking about computers with a lot of non-tech people, who often use the word "glitch" to describe an undesirable outcome of a program or operating system(of course, never Linux!). I have never heard another programmer use the word "glitch" and hearing it makes me think the user has no idea what they are talking about. SO my question: Do you use the word glitch in everyday, technical conversation, if not, does its use imply to you ignorance and lack understanding?
Sign up

Glitch came into computing from the hardware side. In hardware, it has a pretty well defined meaning -- a short-term, unexpected change in the state of a signal. This can happen for a number of different reasons, including noise such as from a nearby radio transmitter or static discharge, or defective design such as not taking propagation delays into account. In early computers (especially home-brewed hardware and such) problems from real glitches weren't all that uncommon, but as designs have stabilized, real hardware glitches have become pretty rare -- to the point that encountering a real problem from one anymore is probably pretty unusual.
But honestly, it's just another general term for the same thing. You can try to split hairs and define bugs, glitches, defects, etc. In the end, it is just something that is not producing the desired output.
My know of many teenagers (16+) using it. At my work especially we don't speak of glitches, bugs or even problems. Since its widely accepted in our organization that if you say "bug" you assuming that there is a problem with out development and we claim liability for it. Instead we say "issues" which need to be assessed.

GENESEO, N.Y. - SUNY Geneseo alumna the Rev. Dr. Iris Banister told students at the college's master's commencement May 7 that they will continually seek success in their careers "because you can, and if you understand your CAN options, then inside of that CAN you will indeed find success."
Banister was the keynote speaker for the ceremony during which the college conferred 51 master's degrees. Geneseo offers master's degrees in education, accounting, and communicative disorders and sciences.
During her address, "Success Comes in CANS," Banister emphasized that success comes from within.
"Success lives in you, and within you are all of the raw resources, talents and skills that you acquired here at Geneseo and other places," said Banister, who received a master of science degree herself from Geneseo in 1970. "You combine them together in different combinations for various situations and circumstances and - voila! - success."
Banister told the graduates that "success is not something that you get. Rather success is what you bring, what you draw out of youself, your vision, your imagination and your skills and talents put into motion - the what of success, your cans and can dos."
Banister is an accomplished author and motivational speaker. She earned a doctorate in Theological Counseling from the Master's International School of Divinity in Indiana and also has a bachelor of science degree from Jarvis Christian College in Texas. She is a member of Geneseo's College Council, a group of community members appointed by the governor to advise the college's senior administration. She also contributes as a board member and gives volunteer service to many non-profit, community based organizations.
The college's 145th undergraduate commencement is scheduled May 14 during which the college will confer an estimated 1,275 undergraduate degrees during two separate ceremonies at 10 a.m. and 2 p.m. Jeff Clarke, chief executive officer and president of Travelport and a 1983 SUNY Geneseo alumnus, will deliver the keynote address, "Choices for Your Next Decade." The college also will confer an honorary doctor of humane letters degree upon renowned poet and librettist J. D. "Sandy" McClatchy, professor of English at Yale University.

GRERRREAT!!! I love this bivi sac! They are super durable and all you need
Santa Barbara, Ca
Nice and light. Much more fun to carry then a tent. The pole that keeps the hood up is actually a thick wire that can be bent into all sorts of positions depending on the protection needed. Entry was not all that easy. I'm 6'1" @ 185lbs and with a NeoAir pad inside it was a task that will require some gettin used to. Keep in mind though the Neo is a large and does take up a good bit of space. Once inside space is not a problem. Just don't expect to have the full freedom of motion like one would have in a tent. Felt very comfortable and the bivy doesn't weigh down on you. No moisture at all. Not a drop. This would be 5 stars if entry was a lil better. I think my tents are goin to be seeing alot more closet time.

ADA, OK - A resale store in Ada is hoping to help the Oklahomans who have lost their homes in the wildfires.
The Wise Owl Resale & More shop on Main street has been open for nearly five years and the store's owner Vicki Wren said she is always looking for ways to help others.
"We have all this stuff here and it all needs to go somewhere," Wren said.
Wren is now offering victims of the recent Oklahoma wildfires to come shop at her store but instead of money, all Wren asks for in exchange for her merchandise is a referral from the American Red Cross.
"We have always done it, but the wildfires have really touched my heart," Wren said.
Cleveland County has been hit hard by the wildfires.
Over the weekend, emergency officials in Norman and Slaughterville reached out to their neighbors in Pontotoc County for help.
"We deployed on Friday," Pontotoc County Emergency Manager Chad Letellier said. "We deployed six different departments and six brush trucks and on Saturday we deployed seven departments."
Wren said although she is a Pontotoc County resident, for her the wildfire hits close to home.
She said her friend and neighbor is a Byng volunteer firefighter.
"He told me about everybody just left and just left them there fighting the fires," Wren said.
"Our group did specifically save some homes and put out some fires and that's what its all about," Letellier said.
The Wise Owl is open from 9 a.m. to 5 p.m. Monday though Friday
and Saturdays from 10 a.m. to 4 p.m.
Wren said they are still accepting donations, but she would really like victims to take advantage of the free items.

I vow to my fellow citizens and to the friends who reside among us, that the State will be vigilant about their security and well-being. Our nation is capable, by the Grace of God Almighty and the unity of its citizens, to confront and destroy the threat posed by a deviant few and those who endorse or support them. With the help of God Almighty, we shall prevail.
Crown Prince Abdullah bin Abdulaziz, Deputy Prime Minister
and Commander of the National Guard, May 13, 2003
Actions to Counter Terrorism
* Questioned thousands of suspects
* Arrested more than 600 individuals
* Broke up a number of Al-Qaeda cells
* Seized large quantities of arms caches
* Extradited suspects from other countries
* Set up joint task forces with the United States
Specific Cases:
Yousif Salih Fahad Al-Ayeeri, a.k.a. Swift Sword, a major Al-Qaeda operational planner and fundraiser, was killed on May 31 while fleeing from a security patrol.
Ali Abdulrahman Said Alfagsi Al-Ghamdi, a.k.a. Abu Bakr Al-Azdi, surrendered to Saudi authorities. Al-Ghamdi, considered one of the top Al-Qaeda operatives in Saudi Arabia, is suspected of being one of the masterminds of the May 12 bombings in Riyadh.
Turki Nasser Mishaal Aldandany, another top Al-Qaeda operative and mastermind of the May 12 bombings, was killed on July 3 along with three other suspects in a gun battle with security forces that had them surrounded.
Eleven suspects were taken into custody on May 27 and May 28 in the city of Madinah. Weapons, false identity cards and bomb-making materials were confiscated. In addition, Saudi national Abdulmonim Ali Mahfouz Al-Ghamdi was arrested, following a car chase. Three non-Saudi women without identity cards, who were in the car he was driving, were detained.
Saudi security raided a terrorist cell on June 14 in the Alattas building in the Khalidiya neighborhood of Makkah. Two Saudi police officers and five suspects were killed in a shootout. Twelve suspects were arrested, and a number of booby-trapped Qur'ans and 72 home-made bombs, in addition to weapons, ammunition, and masks were confiscated.
On July 21 Saudi authorities defused terrorist operations which were about to be carried out against vital installations and arrested 16 members of a number of terrorist cells after searching their hideouts in farms and houses in Riyadh Province, Qasim Province and the Eastern Province. In addition, underground storage facilities were found at these farms and homes containing bags, weighing over 20 tons, filled with chemicals used in the making of explosives.
Three men were arrested on July 25 at a checkpoint in Makkah for possessing printed material that included a "religious edict" in support of terrorist acts against Western targets.
Saudi security forces killed on July 28 six terrorist suspects and injured one in a gunfight at a farm in Qasim Province, 220 miles north of the capital, Riyadh. Two Saudi security officers were killed and eight suffered minor injuries. Four people who harbored the suspects were arrested. Nine security officers have been killed and 19 injured in counter-terrorism activities since May 12.
Security forces surrounded a group of suspected terrorists in an apartment in the city of Jizan on September 23, 2003. During a gun battle, one security officer was killed and four officers injured. Two suspects were arrested and one suspect was killed. The suspects were armed with machine guns and pistols and a large quantity of ammunition.
On October 5, 2003 security forces arrested three suspects during a raid in the desert to the east of Riyadh. On October 8, 2003 security forces raided a farm in the northern Muleda area of Qasim Province and were able to arrest a suspect. Three other suspects fled the scene. Two security officers suffered injuries. Security forces found large amounts of material to make explosives and light weaponry in the farm where the suspects had been hiding.
On October 20, 2003 Saudi security forces raided several terrorist cells in various parts of the country, including the city of Riyadh, the Al-Majma'a District in Riyadh Province, Makkah Province, the Jeddah District of Makkah Province, and Qasim Province. Security forces confiscated items including C4 plastic explosives, home-made bombs, gas masks, and large quantities of assault rifles and ammunition.
On Monday, November 3, 2003, Saudi police arrested six suspected Al-Qaeda militants after a shootout in the holy city of Makkah in Saudi Arabia. The raid on an apartment triggered a shootout that left two suspected terrorists dead, and one security officer wounded. Officers also seized a large cache of weapons they believe were stockpiled for attacks during the Muslim holy month of Ramadan. The militants had rented the apartment for just the month of Ramadan.
On Thursday, November 6, 2003, Saudi security forces encircled two terrorists in Riyadh. The terrorists shot at the security forces and committed suicide by blowing themselves up.
International Cooperation
Defense Secretary Donald Rumsfeld said on November 2, 2003: "The Saudi government, particularly since they were attacked some weeks and months ago, has been very aggressive, more aggressive than ever in the past."
Attorney General John Ashcroft commended Saudi Arabia's efforts in the war on terrorism and stated, on August 29, 2003: "I believe that progress is being made and I think not only that it (cooperation) is good but it continues to improve."
Saudi Arabia and the United States established a second joint task force in August 2003, this one aimed at combating the financing of terror. The task force, which was initiated by Crown Prince Abdullah, is further indication of the Kingdom's commitment to the war on terrorism and its close cooperation with the United States in eradicating terrorists and their supporters.
InMay 2003, a Saudi-U.S. task force was organized from across law enforcement and intelligence agencies to work side by side to share "real time" intelligence and conduct joint operations in the fight against terrorism. The U.S. Ambassador to Saudi Arabia, Robert Jordan, described the cooperation of Saudi investigators with the U.S. law enforcement representatives as "superb".
Saudi Arabia has provided extensive intelligence and military cooperation in the assault on Al-Qaeda. Public disclosures to date have revealed major Saudi contributions to the breakup of a number of Al-Qaeda cells, the arrests of key Al-Qaeda commanders, and the capture of numerous Al-Qaeda members.
Saudi Arabia is engaging other countries to locate and extradite Al-Qaeda operatives who may be hiding in those countries.
Actions Taken in the Financial Area
Saudi Arabia implemented the 40 Financial Action Task Force (FATF) recommendations on the prevention of money laundering and the eight special recommendations on terrorist financing.
Saudi Arabia has established a High Commission for oversight of all charities, contributions and donations.
A Financial Intelligence Unit was established to monitor financial transactions to ensure that funds do not reach evildoers.
The Kingdom of Saudi Arabia and the United States took steps to freeze the assets of a close bin Laden aide, Wa'el Hamza Julaidan.
In March 2002, the U.S. Treasury Department and Saudi Arabia blocked the accounts of the Somalia and Bosnia branches of the Al-Haramain Islamic Foundation. While the Saudi headquarters for this private charity is dedicated to helping those in need, it was determined that the Somalia and Bosnia branches supported terrorist activities and terrorist organizations such as Al-Qaeda and AIAI (al-Itihaad al-Islamiya).
In February 2003, the Saudi Arabian Monetary Agency (SAMA) began to implement a major technical program to train judges and investigators on legal matters involving terrorism financing and money-laundering methods, international requirements for financial secrecy, and methods followed by criminals to exchange information.
In May 2003, Saudi Arabia asked the Al-Haramain Islamic Foundation and all Saudi charities to suspend activities outside Saudi Arabia until mechanisms are in place to adequately monitor and control funds so they cannot be misdirected for illegal purposes.
Also in May 2003, SAMA instructed all banks and financial institutions in the Kingdom to stop all financial transfers by Saudi charities to any accounts outside the Kingdom.
In August 2003, the Council of Ministers approved new money-laundering and terror financing laws that include harsh penalties for the crime of money laundering and terror financing.
Saudi Arabia has investigated numerous bank accounts suspected of having links to terrorism and has frozen more than 40 such accounts.
"After the terrible attacks in Riyadh on May the 12th, the government of Saudi Arabia has intensified its long-standing efforts against the Al-Qaeda network. Recently Saudi's security services apprehended Abu Bakr, believed to be a central figure in the Riyadh bombing, and killed a major Al-Qaeda operational planner and fundraiser, a man known in terrorist circles as "Swift Sword."… America and Saudi Arabia face a common terrorist threat, and we appreciate the strong, continuing efforts of the Saudi government in fighting that threat."
George W. Bush, President of the United States, July 1, 2003

BIOGRAPHYMonica Lin is PhD student in the UC Berkeley - UCSF Graduate Program in Bioengineering, with a research focus on medical devices. She is interested in developing sensors to address unmet clinical needs, and currently works in Dr. Michel Maharbiz's lab designing and building an electronic bandage to monitor pressure ulcers.
Monica received her B.S. in Chemical Biology with a Bioengineering minor from UC Berkeley.
Impedance Sensing Device to Monitor Pressure Ulcers [BPN714]Chronic cutaneous wounds affect millions of people each year and take billions of dollars
to treat. Formation of pressure ulcers is considered a "never event" - an inexcusable, adverse
event that occurs in a healthcare setting. Current monitoring solutions (pressure-distributing
beds, repositioning patients every few hours, etc) are very expensive and labor intensive. In
response to this challenge, we are developing a novel, flexible monitoring device that utilizes
impedance spectroscopy to measure and characterize tissue health, thus allowing physicians to
objectively monitor progression of wound healing as well as to identify high-risk areas of skin to
prevent formation of pressure ulcers. Previous studies that examined the dielectric response of
cell suspensions and tissues have identified several distinct dispersions associated with
particular molecular-level processes that can be used to distinguish between tissue types. We are
utilizing impedance spectroscopy to detect subtle changes in tissue, enabling objective assessment
and providing a unique insight into the condition of a wound. Wireless capability can be
implemented to allow for remote monitoring. In parallel, efforts are being made to transfer this
technology onto resorbable substrates to create a device that can monitor internal wound healing
and readily dissolve after healing.

Since the shooting tragedy at Sandy Hook Elementary there's been lots of talk about whether schools should have armed guards posted.
U.S. Senator Rand Paul stopped by our studio Wednesday night with an alternative for schools that can't afford armed guards.
"I would say that a teacher who has concealed carry permit, who's had instruction in gun safety or a principal, or any other authority that the school district decides, with probably certain rules that the local school district would decide on security, keeping the weapon unavailable to kids and things like that, I think would be a good idea," said Paul.
The senator has been invited to speak to CPAC, a conservative political action committee, in March.
Prospective presidential candidates are often invited to speak at CPAC. Paul told us Wednesday night he would wait two more years before deciding.

I know that you can improve performance and battery life by not having Flash on your Mac. Is there any similar advantage to not installing Java?
Installing java won't have much effect on battery life.
I don't think installing Flash will have much effect either.
Where the issue is is when you hit a website with badly written flash (and to a very much less extent Java) where the animation takes up CPU but you can just leave these sites - you will be no worse off than not installing.
Java is now rare on websites and not really used for parts of the web site the user does not need.
I think a better way is to install a plugin for your browser like ClickToFlash which stops Flash loading until you tell it.
Yes - you won't have to worry about updating software that Apple seems to be less and less inclined to let run. It also has earned a reputation as software that you want to devote time and attention to patching or making sure you never run code you don't trust.
If you're not going to block java in the web and take measures to secure it, you'd be better off not installing java on OS X from a security and maintenance standpoint.
Personally, I decline to instal flash and disable java entirely on my portable Mac so that I have less running, better battery life and less security exposure and reduced maintenance.
By not installing java or flash, you have two less things to update and two less things to run content while browsing the web.
Yes- mid 2010 Macbook pro, OWC SSD 120gb I installed Java and battery life fell to under 2 hours. Uninstalled it and battery life returned to the normal 6 hours. Tested by using laptop until the battery drained. Beware it's a HUGE battery drainer.

LACY LAKEVIEW (January 8, 2013)-A Lacy Lakeview man was held Tuesday in the McLennan County Jail charged with sexual assault of a child.
Navar Jamal Sablan, 26, was booked into the jail early Tuesday morning after Lacy Lakeview police arrested him on a warrant charging sexual assault of a child and attempted sexual assault of a child.
He was also ordered held without bond on an immigration detainer.
Lacy Lakeview police Chief John Truehitt said officers arrested Sablan Monday night on a warrant issued by McLennan County Justice of the Peace David Puryea.
Truehitt said the incident occurred in early January at a Lacy Lakeview residence.
Truehitt said the 16-year-old female victim made an outcry to her parents after the assault and police were notified after a Child Protective Services worker interviewed the girl.
According to the police report the victim did not require medical attention for injuries.

CHESTER - Mountaineer Casino, Racetrack and Resort concludes its live season on Friday with a nine-race card, highlighted by a 2-mile marathon event. Full fields of 10 horses have drawn in for each race. Post time will be 7 p.m.
Scheduled as the eighth race on the card, the marathon carries a $30,000 purse for starter allowance runners. Romance Argentino, a 3-year-old gelding who is the 9-5 morning line favorite, registered a track record in his most recent effort, clocking a final time of 3:51.81 for 2 1/8 miles at Mountaineer on Nov. 30. Christian P. Pilares has the mount.
Friday's marathon field further includes the 6-year-old gelding Getta Rhythm, the prevailing Mountaineer standard holder for 2 miles. Getta Rhythm registered a final time of 4:03.16 for that distance on Sept. 3. Terry D. Houghton will be aboard.
Two and one-quarter miles constitute a long way to go, and few U.S. tracks card races at that distance. Friday's marathon will begin at the rarely-used chute at the top of Mountaineer's stretch, and will require more than two complete circuits of the racing oval.
"We race 210 days a year, and we like to include as much variety as we can," said Joe Narcavish, the racing secretary at Mountaineer. "In 2012, we have conducted races on the dirt at 13 different distances, ranging from 4 to 18 furlongs. And we've also run on the grass at eight different distances, ranging from 4 to 15 furlongs.
"If you look further at the statistics, 20 percent of our races have been decided in photo finishes, and 20.1 percent have resulted in wire-to-wire victories. Our racing programs are not designed to one particular style of running. Everybody has a chance."
One sees some very swift horses at Mountaineer. The victory by Guam Typhoon in the $100,000 Senate Robert C. Byrd Memorial Stakes on the Aug. 4 West Virginia Derby undercard was recorded in a time of 1:08.59 for six furlongs. That same day Golden Country won the $100,000 West Virginia Legislature Chairman's Cup in a time of :50.95 for 4 furlongs.
Both clockings were the fastest for their respective distances at Mountaineer this year. Guam Typhoon was the 7-5 post-time favorite in his race. Golden Country exited the starting gate at odds of nearly 14-1. Narcavish's belief that "everybody has a chance" bears merit.
Friday's card, which offers a total purse distribution of $127,900, includes races at five different distances. There are a quartet of 5-furlong sprints, a pair of six-furlong sprints, middle distance races at the one-mile and one-mile plus seventy-yard distances, and the marathon.
Hunch players might note that the 5-2 morning line favorite in the ninth race on the card is named Final Curtain. The 3-year-old gelding has recorded two wins and five placings at Mountaineer this year, and has drawn the rail post. Betty Jo Williams will ride.
Born to Disco, the even-money morning line favorite in Friday's seventh race, has recorded five wins from eight starts at Mountaineer this year, and has a career record of eight wins and five placings from 19 starts at the Hancock County track. The 4-year-old filly will be ridden by Jareth Loveberry, who since Oct. 1 has led all Mountaineer jockeys in victories with 59.
The simulcasting of races from tracks around the country will continue at Mountaineer's Grande Hotel racebook throughout the winter months. The 2013 live racing season will commence on March 1.

The minimum password length recommended is about 8 characters, so is there any standard/recommended maximum length of the password?
Bruce Schneier has a couple of interesting articles on password policies.
Real world passwords - covering password length, complexity and common passwords.
Password advice - some do's and don'ts including:
and many more
Changing passwords - a detailed discussion on how often you should change based upon usage and threat environment.
Good answers so far, but I would like to suggest another possibility: pass phrases. As StackOverflow's own Jeff Atwood suggests, if you aren't prohibited by technical limitations, you might consider allowing and suggesting pass phrases. You could enforce them, but that would probably alienate some users on most sites. Due to their length, they can be significantly more difficult to crack, and they can also be easier to remember than a password like "A1lUrB@se!" or things like that.
The answer to this one, like a lot of questions in Security is "it depends".
There's several factors to consider when looking at password length. First up is some of the things that a long password is designed to protect against, which is generally a brute-force of password guessing attack (online or offline).
For online password guessing, if you've got a relatively aggresive lockout policy (eg, 3 incorrect attempts and then an indefinate lockout) then attacks against a single account will be unlikely to succeed unless the attacker has a good idea of what the password is going to be.
If you're looking against attacks on a large population of users with the same lockout policy, where the attacker can work out the usernames (eg web forums), then the most important element is probably that the passwords used aren't any of the really common ones.
As an aside, one thing to watch for on the account lockout side, is that aggresive policies here for on-line applications can make a Denial of service attack quite easy, without additional countermeasures.
If there's a risk of offline brute force then password strength becomes more important. the problem here is that improved processing power and methods of attack make this a moving target in terms of strength. Realistically I'd say that you'd be looking at 10+ characters and strong enforcement that passwords aren't on common dictionary lists (like @andy says passphrases are a good option here).
Another factor to consider here is your user base, and how the application is used. In some cases, I'd say that very strong password requirements can actually lead to a less secure application. If you have an application where the users are in the same place (eg, a lot of corporate applications) and you make the password policy very "strong" (both in terms of password length and rotation requirements) then it's likely that users will start writing down their passwords, which probably defeats one of the goals of security for that application in the first place.
One good source of a lot more information on this is a book called Authentication: From Passwords to Public Keys
If you're going to be hashing the password, why set an upper limit?
It's not like you need to worry about hitting the max char limit on text fields, web-based or otherwise. So you could conceivably just set a maximum of a few hundred characters just to limit some boundary conditions of whatever text fields you're using.
Of course, if you're talking about generating a password that you'll try to use on multiple sites, then never mind; no one out there seems to agree on it. Even worse, I've found sites that have different max char limits on different input fields, so to log in you have to first type it wrong before being given a different field that happens to allow more characters. Of course, if every site just let it be the minimum expected abilities of a typical text field without trying to artificially limit it, then about 2k characters would be allowed, and you wouldn't have to worry about this at all.
Edited to add: something mentioned in passing here made me pause:
It might thus be worth putting a reasonable limit on both setting and attempting passwords if you're hashing things in a way that's meant to be as computationally expensive as possible. A few hundred characters might still keep things from exploding too much, while still being way more than a user might ever try.
There should not be a maximum password length -- if the user accepts to use a very long password, then he should be commended, not blocked.
Software being what it is, several systems will enforce a limit on password size, mainly due to GUI issue, poor programming, or backward compatibility with much older systems. For instance, old Unix systems used a password hashing process which used only the first eight characters, and totally ignored all others. Similarly, old Windows systems had an internal limit to 14 characters. Therefore, it is best if the password, when truncated to its first 14 characters, is still "strong".
However, the only limit on maximum password size should be the user's patience. There is no point in enforcing anything here.
I'd personally go with using a password generator (like lastpass.com or 1password) to generate and use passwords of minimum 8 chars and max 32 chars (since not all sites support password length more than 10 or 15 ) and use one master password for authentication.( This again depends on your trust on sites like lastpass.com) or a client side encrypted 1password utility for Mac and Windows) .
It is not advisable to use a set of passwords for all sites. Forums in particular email me passwords in plain text. Some sites have the feature to send in plain password in case you use "Forgot Password" feature.
Usually, the restrictions are set up at the server (for websites) . We need to blame the servers we use to not set restrictions on user passwords.
In short, use different passwords each time. In case you have more than 10-15 passwords to remember, its time to start using a "secure" password manager. (For the record, firefox password manager is not at all secure)
16 characters.
This gives you 96 bits according to Wikipedia, which is well beyond anything crackable according to that article.
Personally I use a password program for my mobile phone, combined with Firefox' Master Password feature. My master password has more than 25 characters and is based on Dice Ware, which makes it fairly easy to remember. Almost all my passwords are randomly renerated, since Firefox remembers them for me anyway.
I was at a client where the security officer was insane. He wanted to use every single password complexity policy possible. (Novell eDirectory has a LOT of password complexity issues, and he wanted to use an additional plugin to add more!)
To the point it would be impossible to ever generate a password that can be remembered. I was expecting the unwashed masses to find him, and tar and feather him after it was implemented.
In other words, you can take it too far.
A common minimum today is 12 characters, which is just barely large enough to prevent brute-force cracking by a reasonably well-funded organization within a reasonable amount of time.
As far as maximum length; here are a few thoughts: a password longer than a few hundred bytes is almost certainly malicious (e.g. SQL injection attempt). Also note that if you're hashing your password (and if you're not, you need to start over), then passwords longer than your hash output don't add any more entropy. Note that by "longer" I mean the same number of bits in your keyspace, not the same character length. So while allowing passwords longer than the hash length should be allowed as a point of convenience, it would not make sense from a math point of view for such a thing to be required.
Requiring mixed case doubles the size of your alphabet, which yields huge complexity returns and probably should be required. Requiring numeric characters adds maybe 20% more to your alphabet, which isn't quite as big a deal, and requiring symbols adds maybe 16% to 40% more on top of that (depending on what symbols you count), and again, not quite as significant a return, but certainly shouldn't be disallowed.

Solve $x^{y^2}=y^x$ which $x,y\in\mathbb{N}$.
I can observe that $(x,y)$ can be $(1,1)$, then I don't know how to carry on. Please help. Thank you.
p.s. I wonder if there's solution without using mod.
I can observe that $(x,y)$ can be $(1,1)$, then I don't know how to carry on. Please help. Thank you.
p.s. I wonder if there's solution without using mod.
By the argument I have added below, we establish $x = my^2$ if $x > y$, for $m \in \Bbb N$.
Plugging in gives: $(my^2)^{y^2} = y^{my^2} \iff my^2 = y^m \iff m = y^{m-2}$. Demanding that $y\ge 2$ implies that $m \le 4$.
EDIT: The argument that $x = my^2$ if $x > y$:
Suppose that $x > y$. We have
$$x = \log_y y^x = \log_y x^{y^2} = y^2 \log_y x \implies \frac x{y^2} > 0$$
so that $x > y^2$. Now for any prime $p$, we have:
$$x \operatorname{ord}_p y = y^2 \operatorname{ord}_p x$$
Therefore, if $\operatorname{ord}_p y > 0$, it must be that $\operatorname{ord}_p x > \operatorname{ord}_p y$ to be able to have equality. That is, $y \mid x$.
So put $x = ny$ with $n \in \Bbb N$. Then $n > y$ since $x > y^2$, and:
$$(ny)^{y^2}=y^{ny} \iff n^y = y^{n-2}$$
Resorting again to the $\operatorname{ord}_p$ trick, we find similarly that $\operatorname{ord}_p n > \operatorname{ord}_p y$, i.e. $y \mid n$. Therefore, $x = my^2$ for some $m \in \Bbb N, m \ge 2$.
EDIT 2: The argument that $x \ge y$ for any solution, thus completing the proof that all solutions have been found (since $x = y$ only gives $(1,1)$ as solution):
Suppose that $x < y$. Then since $x < y^2$, employing
$$x \operatorname{ord}_p y = y^2 \operatorname{ord}_p x$$
again yields $x \mid y$, say $y = nx$. Then we obtain, plugging this into the equation:
$$x^{(nx)^2} = (nx)^x \iff x^{n^2x} = nx \iff n = x^{n^2x-1}$$
Because $x \ge 2$, this has no solutions for $n \in \Bbb N$.
It thus follows that the solution space is given by:
$$\left\{(x,y) \in \Bbb N^2: x^{y^2}=y^x \right\} = \{(1,1), (16,2), (27,3)\}$$
You can rewrite the equation as $x = y^{xy^{-2}}$, plugging this into itself gives $x = y^{y^{xy^{-2}-2}}$, and by taking logs (and supposing $y > 1$) we get $y^{xy^{-2}-2} = xy^{-2}$. Finally, raising to the $y^2$th power, we get the equality $y^{x-2y^2} = (xy^{-2})^{y^2}$
If $x > 2y^2$, the LHS is an integer, the RHS is a rational to an integer exponent. This forces the rational on the right to be an integer, and so $x$ has to be a multiple of $y^2$. So $x = my^2$ for some $m > 2$. Then the equation simplifies to $y = m^{1/(m-2)}$ which has the two solutions for $m=3$ and $m=4$
If $x \le 2y^2$ we can take the inverses and now it is $y^2$ that has to be a multiple of $x$. If $y^2 = mx$, we get $(x^{2m})^x = (mx)^x$ thus $x = m^{1/(2m-1)} < 2$, and this is possible only for $x=y=m=1$.

Today, most people work using their brain. So how to think is a very important problem. Although the faced problems are quite different, there are many general rules are very helpful. For example, we should focus on one thing; We should try to find the simple method. It is useful to visualize something, and so on. Now, where can I find some books or web for tips for thinking? Thanks!
I've recently written about some rules for problem solving on my blog. My 8 year old son and I have figured them out to help him tackle his maths homework, but I've found that they work for other things, too.
These rules are:
Other rules I've yet to cover:
You might enjoy the book Pragmatic Thinking and Learning: Refactoring Your Wetware by Andy Hunt.
The book covers a lot of subjects on improved learning and creativity. It's well-researched. I virtually guarantee that there's a trick or technique in there that you haven't heard of. I had heard of about 10%.
Simplest way ... Our brain has to be use too with any thing around the world. so shortest answer would be practice a lot. Think about every thing. Think about problems in any way. Read about others how they solve their problems. If some how it not works for you but as many time your mind will get into practice he will automatically starts building patterns for you.
In my experience, effective thinking really depends on the context. Thinking for a programming logic may be entirely different from thinking about a drawing a piece of art or composing a piece of music or making a new variety of pie etc. In some basic fundamental factors like concentration, surroundings , willingness, all thinking may be same.. but on deeper level, you have to define your own set of rules.. :)
here are some great links that can help you set your answers...
The 5 Elements of Effective Thinking By Edward B. Burger
Effective Thinking - Online De Bono Course In Thinking http://edwdebono.com/course
Some clear concepts on effective thinking http://ictnz.com/Thinking%20Pages/effectivethinker.htm
I've enjoyed reading the book
Nice question, first of all we can relax and think in multiple ways for a problem then we can find many ways, from these we should analyse with help of websites and select a solution best for us suitable with that situation.
