I like the flavor and texture of corn tortillas (store-bought), but they always tear apart whenever I try to use them in a non-flat way - enchilada-style, for example. How can I make the corn tortillas soft enough to work with (to roll around some ingredients, for example)?
You need to warm them up a bit. There are a number of ways to do this - 20 or 30 seconds on a griddle (or a comal is you have one), wrap a stack in foil and place in 325 oven for until warm, wrap a stack in a clean towel and steam them using a steamer, or slightly moisten a towel and wrap it around a stack and microwave them for a bit, etc etc. If you've warmed them and they are still tearing then your tortillas are no longer fresh.
If possible, don't buy your tortillas from a modern super market, but look for a source of homemade/fresh tortillas. These can be found in many cities in the U.S. at Mexican or Latin American stores or neighboroods. Perhaps check your yellow pages for "Tortilleria" (The spanish word for "Tortilla Store"). These tortillas will also taste much better (at least in my opinion), and have fewer preservatives or other additives (such as artificial colors, etc).
If you can find a good source of fresh tortillas, they will generally be much softer than those you buy pre-packaged in a supermarket. They will be fresher, and if you find a good source, they'll be sold to you still warm (often kept in an ice chest or similar, to keep them warm until sale).
If you can't find this, you can learn to make your own tortillas.
Or, you can do as @djmadscribbler suggested, and warm your tortillas gently. Between warming and using, keep them covered so they don't dry out or cool down. Don't overheat them, or you'll dry them out (especially if you're warming them individually on the stove).
I spread coconut oil on the tortilla (thin layer like butter) and heat them in a hot skillet for about 15 seconds per side, drop it in the enchilada sauce, stuff and roll. That way the tortilla gets pliable, the sauce gets on the tortilla, and the sauce helps it stick together and look nice and neat. I've tried many ways (enchiladas are one of my favorite dinners to make with leftover beef or chicken) and this one has proven to be the easiest for me.
My husband is Mexican grew up in Puebla, Mexico, the proud "mecca" of Mexican cuisine. His family puts their corn tortillas in a plastic grocery bag and microwaves them for a few seconds. Or, they warm them in a frying pan in olive oil for a few moments on each side, long enough to soften but not crisp them. I've never seen Poblano cuisine use crispy tortillas.
I used to make enchiladas all the time and what I did was dip the corn tortilla in hot oil briefly, flip and do it again. However, now the tortillas I get turn mushy and tear easily, so I think something about the tortillas in my neightborhood has changed.
A friend's family's technique is to fry them in oil until they are almost hard enough for tostadas since she explained that the enchilada sauce will soften the tortillas once they are cooked.
Using tongs, dip corn tortillas in hot manteca (lard) briefly on both sides, and drain on paper towels.
Just made a large pan of chicken enchiladas. Heated the corn tortillas in a small, dry skillet (no oil). This is the first time I have not either dipped them in enchilada sauce or fried in oil. Was able to easily roll them, except for repeatedly burning my fingers. :o( I think I prefer the dry way, as I'd rather not add additional calories if I don't have to. [Note: the tortillas were pretty fresh, which I do believe helped.]

Under Compiz :: General Options :: Desktop Size I already have 2x2 layout of 4 virtual desktops setup, as in screenshot.
However if you notice as in the switcher app parked in the top left corner, only one desktop shows, and indeed only one is available to send windows to or hover over to.
Right-clicking that docked switcher to "Add a workspace" doesn't behave right anymore. It's like the desktops are too independent and trying to send windows to Right/Down isn't an option anymore from the Alt Space menu. Nor do hotkeys CTRL-ALT-Arrow work to slide over anymore. Double-Clicking does switch desktops though, but it's like they're in otherwise unrelated Xwindows sessions(cannot be, of course).
For a while I've been stuck with a stubborn 1x1 or 1xN layout, unable to figure out why it won't go to 2 columns, until I discovered the Compiz :: General Options :: Desktop Size :: "Number of Desktops" had mysteriously gone to 0. Horizontal and Vertical were both still 2 there. (Weird things happened when I next made that 0 into 4--Switcher at first drew 16 virtual desktop boxes, after which I decided to collapse everybody into 1 desktop and start again from there.) My
~/.dmrc contains only:
I noticed each has a title now: Work / Game / Video / Chat, maybe they were present before I had to reboot from a total Xwindows unresponsive freeze(though switching back and forth from text consoles Ctrl Alt F1-F6 still worked) twice, but I don't recall titles before.
After some updates to cairo-dock and many other packages since Feb, notice 16 workspace boxes manifested themselves again, though only 4 seem switchable via ctrl-arrow keys:

I am very confused between the concept of known-plaintext attack and chosen-plaintext attack. It seems to me that these two are the same thing, but it definitely is not.

migrated from security.stackexchange.com Jun 10 '12 at 18:58
This question came from our site for information security professionals.
It's the difference between an active and a passive attacker:
So the second type of attack is a lot more powerful.
A known plaintext attack is that if you know any of the plaintext that has been encrypted and have the resulting encrypted file, with a flawed encryption algorithm you can use that to break the rest of the encryption.
Example: We saw this with the old pkzip encryption method. In this case if you had any of the unencrypted files in the archive, you could use that to obtain the key to break the rest.
A chosen plaintext attack is the same thing except you get to choose the plaintext which can be useful. In this case the attacker determines what will be encrypted and then uses the result to determine the key (or perhaps other less useful information) of the encryption.
Example: A good example here is XOR encryption. If you can choose the plaintext and get to see the result, you can use those to easily determine the key being used.
You could also use a known plaintext attack with non-salted hashes. So if I choose a password and can see the resulting hash, I could search to see if there are any other similar hashes and therefore know they have the same password.
So yeah they are basically the same thing, its really just a matter of what you have to work with or what you are trying to accomplish.
As others have pointed out, there are some ciphers that can be broken if all you have is a known plaintext and the ciphertext. In general, because of this, those ciphers are considered very vulnerable and are not used anywhere. Or I should say, where they are used, the keys are generated (pseudo-) randomly and only used once.
However, if the attacker can choose the plaintext, more commonly used ciphers become insecure. In particular Public-Key cryptography has a glaring weakness in this regard, because signing a plaintext is exactly the same operation as decrypting a ciphertext. If an attacker can get a target to sign a message anyone encrypted with the target's public key (i.e. sent to the target) and retrieve the signature, then the attacker has recovered the plaintext of the message. This is one reason digital signature schemes are set up to only sign a hash of the message, not the entire message itself.
In more sophisticated attacks, using large numbers of chosen plaintexts can reveal patterns in the ciphertext that in turn reveal some if not all of the bits of the key. Usually, though, the number of chosen plaintexts is huge: millions to trillions or more.
A cipher that is vulnerable to known plaintext attacks is of course vulnerable to chosen plaintext attacks, but more importantly can be broken without any access to the encryption device. Intercepting the communications alone compromises the cipher. On the other hand, chosen plaintext attacks do require access to the encryption device, and thus are considered secure as long as the encryption device itself is secure.
Known Plaintext Attack
You sniff a lot of thhing about your victim but every of them is ciphertext so you don't know anything about them. And you learn o plan text of your victim by any means; but you don't know the plaintext is which ciphertext's. So you must solve this problem.
Choosen Plaintext Attack
You know a plaintext and you know the plaintext is which cipertext's. And you try to solve the algorithm of encryption system.

5 Insane Celebrity Conspiracy Theories (That Make Sense)
#2. Elvis Presley Died From Chronic Constipation
The popularly accepted theory on the death of Elvis Presley is that he died as a result of cardiac arrhythmia (aka irregular heartbeat), possibly brought on by drug abuse and a gut-driven instinct to prove bacon and peanut butter were God's medicine.
And we've always presumed it was that last weakness that ate phat Elvis and left fat Elvis in his place. But one doctor (who also happened to be Elvis' personal physician) doesn't think it was necessarily his heart or his appetite that got him in the end.
Think lower. And browner.
The Theory:
Dr. George Nichopoulos thinks Elvis Presley died from chronic constipation. Before you say, "Hey, that sounds like a load of crap," please understand, the doctor makes a pretty hefty, odorous case. According to the doctor, constipation plagued Elvis for most of his "fat" years. In fact, he claims that those weren't even "fat" years. They were more like "holy mother of God, that guy has six months of fecal matter in his colon" years.
"It was really a physiological problem. During the last few years we were going back and comparing pictures, some of them were taken just two weeks apart but he looked like he'd gained 20 pounds when the only difference was that he had a good healthy bowel movement and then lost a lot of weight from that."
"The King needs to fire off a hunk of burning love."
Delicious! An autopsy revealed that his status in the rock community wasn't the only king-sized thing about Elvis. His colon was 5 inches in diameter, a good 2 to 3 inches larger than normal, and it was approximately 8 to 9 feet long. A normal colon is only 4 to 5 feet long. Which was why Nichopoulos was in talks to give the Pelvis a colostomy.
Seeing as how he was sporting a nine-footer, Elvis certainly had colon to spare, but the shame of admitting to poop problems in public was too much to stomach, and the potentially lifesaving surgery never happened. Instead, the man who invented rock and roll (for white people) stuck with a series of more traditional constipation treatments that led to frequent accidents and wardrobe changes on stage. Sad.
"Oh my God, how'd you get it on your scarf?"
For his part, Nichopoulos believes that the King would still be with us today if the procedure had been done.
Oh, hey, now that this article is about poop ...
#1. Hitler's Sadism Came From a Poop Fetish
Alright, we're not going to lie. Things are about to get nasty. Not only are we going to be talking about supreme devil #1, the big one, the grand slam of evil, but we're also going to be talking about the things that came out of his butthole. And why it gave him a boner.
We're so sorry. We really shouldn't have put this in the article. Editors, make sure to just cut this whole part before it runs.
The Theory:
In Freudian psychology, all kids have an "anal stage" of sexual development, around the time they start potty training. Supposedly if something weird happens in that stage that makes a kid fixate on the experience, it can manifest itself later as a sexual fetish. Hitler, for instance, was reportedly one of those people. We know because his girlfriend/niece Geli (you read that right) blabbed all about his feces fetish.
We don't have the stomach to write out the manifestations of this obsession, but it was bad. Real bad. Read up if you want, cowboy. But we're not going there. He was Hitler, and he was obsessed with poop, and that obsession got him aroused. Use your freaking imagination.
He insisted on his photos being taken in brown and white.
Now, here's where things get even weirder, if that's possible. Psychologists have speculated that the fixation came from his mother's harsh methods during potty training. Her abusive tactics apparently instilled in him an obsessive fear of germs and anything dirty (the "forbidden" nature of poop apparently being what turned him on).
Now, when it came to Adolph's feelings about the Jews of Germany, he uses some despicable language that we're obviously not going to repeat here. But you don't have to be a genius psychologist to see this bizarre link that he makes between the Jewish people and all things dirty. His mind not only made this insane connection, it also associated destroying all germs with destroying all "dirty" cultures. The obsession with "cleansing" humanity influenced his politics and made the foundation for his "sadistic character."
"Oh, man up, baby. It'll wash out."
So, to recap, Hitler's mother instills in him a fear of, and obsession with, excrement and dirtiness. This becomes an obsession with germs and cleanliness. Hitler decides the Jews and all non-white races are unclean. And the rest is horrifying, nightmarish history.

Judging by the 'PT test' you're a soldier. I served 4 year in active army. One of the first things I learned when running about breathing that I still do to this day is to control your breathing by SOLELY breathing through your nose. My mouth is closed the entire time while running. I treat breathing out the mouth as a 'treat'. I have certain point on my run where I take 3 deep breathes through the mouth. I find that breathing through the nose help you conrol your breathing. Yesterday I ran 10 miles and never once was I 'out of breath'. It may take some getting used to but try it, it works!!!
Not that I'm an expert or anything BUT I know of a lot of running who just breath through their nose when running and sporadically take breathes from the mouth when necessary. It probably wont be easy and it will take some time to get used to but I suggest you give it a shot. I wouldn't suggest you try it on you PT test. Test it out while running on your own free time (if there is such a thing)
When I use to run with my mouth open breathing through my mouth, I constantly got cramps in my sides. After I learned to control my breathing I haven't had a problem since. You probably need to learn to find 'your pace' too. That will also help with breathing.
I'm 5' 8" and I weigh about 185 pounds. Running for me was never easy until I got comfortable doing it. Now that I got control of my pace, comfort (which includes running style, clothing) and my breathing I finally broke the 10 mile point WITH EASE!!!!!!
If I know the military like I think I do, you run in formation. Which means you pretty much have to run the pace of the man who's in charge of PT that day. That pace maybe too slow or too fast for you. Both of which can be harmful. You probably have to find your style, pace and comfort level on you time.
Good luck Bro!!!!
Don't have any answers for you since I'm just getting started back running myself. I also served 4 years active duty Army, so...
It must be nice to not have constant sinuses and be able to breath only through your nose. Im a mouth breather and cant help it. The way I look at it is get the oxygen no matter how you do it even if you gotta breath through your ears lol. In fact I probably sound like a freight train coming up behind runners but hell if im passing people half my weight what does it matter
Obsessed is a word the lazy use to describe the dedicated-
Gladiator 5k Obstacle Race Cary, NC 63 out of 776 (10 percentile)
Run for the Roses Raleigh, NC 123 out of 473 (26 percentile)
I can't really help with the breathing thing since I have issues with this myself.
I used to have a problem with shin splints too then I watched this video on YouTube and I haven't had any issues with shin splints this time around -> http://youtu.be/rkUqkdPQHis
Thanks to all the other replies too, I have got some new things to try out regarding breathing that may help with the stitches I have been getting!!

Hey Matt, glad to see you've broken through your barrier! Technical fabrics are awesome, aren't they!
On the first poster's questions.... Re breathing, my nose is constantly stuffy, despite allergy meds, so I breathe through my mouth when running above a certain effort level. For my long runs (10+ miles) I have used an extra decongestant before I go out so that I can eat or drink and breathe at the same time, and that's been helpful. I don't officially have asthma, though, so can't offer much advice there. But I'd just add that relatively deep controlled breaths, however the air gets in, are worthwhile -- I often count (two steps breathing in, two steps out, or three, or four, or whatever seems right) in order to focus my attention on my breathing from time to time while running, and that seems to help me if I'm struggling (as does slowing down, which may not be an option in PT!).
If you've got short legs, you just may not be able to lengthen your stride much without causing too much stress on various body parts -- shins, knees, hips, IT band.... But as you get stronger, you'll get more force from your calves with each step, which will allow you to cover more ground with each stride even though your feet aren't reaching further forward. I've noticed that for myself, and amy really grateful for it. It takes longer to happen than just lengthening your stride, but a stride that's too long for you is not sustainable. My dad is only 5'6", and he recalls that when he was in basic training, there was just no way to keep up with the same number of steps as the 6'2" guys all around him.
If I'm remembering right, you said the 3-3 jogging-running intervals were too hard and you tired out by 12 minutes. So, I think you've answered your own question there -- the right interval for you is less than 3-3, and/or your pace for the jog and/or run is too fast for that interval! I tried a 2 minute jog, 30 second fast run (NOT sprinting), and a minute walk, repeated for about 20-25 minutes, about halfway through C25K, and that worked for me. The walk allowed me to recover faster than if I'd tried to just keep jogging, and the faster running segments helped build calf strength. But you can see what works for you. Hope the PT test went well!

In Magic the Gathering, the decks are required to be no less than 60 cards, but can be larger. Since you can only have 4 of each card (except for basic lands), it seems you would want the limit size to improve your chances of getting the cards you want. Why would you want to play with a larger deck?

You can easily run yourself out of cards if you build a standard-sized deck based around card-drawing, decking mechanics (where you try and exhaust your opponent's deck), or graveyard-pilfering (where you want to get as much stuff into your graveyard as possible). This can quickly happen if you play with Recycle, Worry Beads, Anvil of Bogardan, Riptide Director, Tolarian Serpent, Cephalid Vandal, Prosperity, Ambassador Laquatus... or any of the infinite card drawing combos. These are some of my favourite kinds of decks for casual play, and are routinely large.
Another strong argument is if you expect to be on the receiving end of someone trying to 'deck' you. I built a deck specifically for this purpose after getting annoyed with my friend's Millstone deck. Clearly this is not a general approach, but is handy for wiping the smirk off your regular gaming partner's face. ;)
A third reason is if you want to keep your deck general, and include lots of options for dealing with different types of enemies. You can build powerful decks around this approach, using the idea of cycling, digging or searching through your deck with e.g. Tutors, Skyship Weatherlight, Captain Sisay, and so on, to find the exact card you need for any situation.
From a strategy standpoint, my answer would be "You wouldn't".
The mathematics of probability in drawing from a 60 card deck vs a 61 or 62 card deck change (almost dramatically). Here's an interesting article.
However, I think that often you can start with more than 60 cards when 'testing' a deck. Often you find that a card doesn't fit or 'play nice with others' and should come out. Same with cards that you draw and think "I wish I hadn't drawn that". Those cards come out also.
So to summarize, when testing ideas, 60+ is okay. For tournament play, reduce to 60.
You might be playing in a format that mandates it. One example is Commander, which uses a deck of precisely 100 cards, with no cards repeated save basic land.
Adding diversity seems to the biggest reason you'd want to go over 60. Since most decks are designed around getting certain cards, increasing the size of the deck beyond sixty decreases the probability of drawing any one card. Since a deck is limited to only four copies of a non land card usually, this added diversity comes at the cost of significantly reducing the chances of getting a certain card in a given game.
I think for players looking to experiment, or looking for decks that deliver truly random results, having a deck larger then sixty isn't an issue. Larger decks could be fun for some people to play since they can have a much larger selection of spells, but I don't there are any strategic reasons for doing.
Larger decks are going to be much less constant on getting the cards you need, when you need them. Most magic decks are highly focused one or at most two strategies for winning. Especially when your looking for a certain card combination to win, having extra cards will just reduce the odds of you getting the cards you need.
Effective Magic decks thrive on consistency. Exceeding the minimum deck size is only worth it if it gives you a powerful benefit you can't gain otherwise, like a surprising way to attack the metagame.
Pushing your deck above 60 (or 40) cards makes it harder to find key cards, increases the risk of "mana flood" and "mana screw," and makes it more likely that you'll draw unplayable hands. Generally speaking, this is not a good plan! Even in a casual environment where playing an optimal deck might not be your top priority, losing because of flood/screw or bad mulligans isn't fun.
Pro Tour Hall of Famer Frank Karsten wrote an article called "Is Playing More Than 60 Cards Always a Bad Idea?" to examine some special cases. His findings:
It's okay to experiment with deck size, but you should go into it armed with a good understanding of Magic strategy and probability, and the awareness that the overwhelming majority of such experiments are going to fail. In contrast, you pretty much can't go wrong playing exactly 60 cards in your Constructed deck, or 40 cards in your Limited deck.
Travis Woo has an interesting article, "90 Card Living End", that has a good explanation of yet another reason to have more than 60 cards: his deck is based on a combo that relies on the card Living End being in his library.
Actually drawing Living End is a problem for the deck, so he plays more cards because he doesn't want to draw the most important card. He could play fewer, but he finds that he needs to combo off several times in many games, so he doesn't want to. He can make 90 work because there are good alternatives available for the other cards so he doesn't lose much in quality.
Anyway the article has good explanation on this topic.
Really I think that the 60 card idea is good as it allows you to have a higher chance of getting lands (which are needed for winning in almost any situation). Also when i play a deck of over 60 I lose most games but 60-65 does well so you can go over 60 to do well but don't go mad and go like 80-infinite. :)
Why would you play with a larger sized deck? 1- More fun 2- To show those who rely on law of probability that you can throw that out the window when you're dealing with thousands of options(number of existing cards.) It's the exact same science that "proves" that there is no life on other planets. Take a good look at the math for that. Nowhere is there mentioned number of possible planets which, until we know more, is infinite. Every math that I've seen has always ignored other parameters that should be in the equation.
The theories for most card mechanics involve 52 different cards(54 if you count the jokers). Even this is sat on it's head by the sheer determination of luck involved.
With that in mind, I wouldn't build an aggro deck over 60, or ones that rely on certain combos. You want fewer cards for that and I'd actually prefer fewer cards. If you want to build a defensive deck, then by all means, go over 70 if you want to. Use cards that have more than 1 use. Use card draws. If the others want to stick to 60 out of some fallible math, then by all means, run a milling deck on them until they beg for mercy.
In a game that is filled with variety, I cannot understand why players are so stubborn as to not be innovative. Before you quote someone's fallible math, try and prove it wrong. You'll be surprised at the results.

Because of the nature of my job most personal electronic devices are off-limits at work, including accessing personal e-mail accounts. Likewise, I cannot access work e-mail at home, and really should leave work stuff at work.
The best I can come up with is getting a spiral notebook that contains a place for me to write down things that occur to me while I'm at work, but that means I don't have the One Trusted Place for my stuff.
Has anyone else gotten around this?
Edit: Thanks for the answers everyone. I probably can get away with sending e-mail back and forth, but I'd prefer not to do that. Internet activity is monitored but I've never gotten called on anything. My smartphone can't come into the building, but I could leave it in my car I suppose.

Perfect software doesn't have bugs, and therefore doesn't have unexpected behaviors that lead to security vulnerabilities. If you only use perfect software, then you never need to patch, can never be exploited, and any security breaches are a result of your own operational errors. However, with the exception of a couple of fine applications from DJB, there are precious few programs that approach this level of software perfection, creating something of a supply problem for people who desire secure systems.
Therefore, we need a Plan B: some way to make our systems survive the inevitable software defects that come from using large scale commodity software. This approach goes by many names: DARPA has called it "survivability", the security market has called it "intrusion prevention", and classical security research has called it "secure design" J

Sylvester Stallone: 'Old actors shouldn't retire'
SYLVESTER STALLONE has urged ageing stars to give up retirement dreams - because they owe it to their fans to just keep going.
The veteran action man has revived his career with The Expendables franchise and admits he has no time for old-timers like Jack Nicholson, who opt to quit acting and retire.
He tells WENN, "Age is a state of old mind. It gets to the point when you get old enough you forget how old you are and that's the best thing. You walk around kind of like in a fog. So you really don't know how old you are and it's beautiful. And then you find yourself watching Teletubbies drunk one night! I'm not ready to sit at home and play with Pomeranians (dogs) 12 hours a day. So you keep going.
"Remember, in old vaudeville there was a cane that snatched you off the stage? Well, I'm waiting for that until they just hook me off and that's it. Actors don't want to retire. They're usually forced to retire and that's sad because you get better as you get older. You may not remember as much dialogue, but you do remember you're better at it.
"We're just adult children and we're there to perform and when that's taken away... I've always said that the artist dies twice. And the first death is the hardest, which is the career death and the creative death; the physical death is an inevitability.
"I think everyone should just keep going and I think that's happening. I think the genre is opening up and television is providing more alternate careers for second acts in adult actors' careers."

Critical Engine Cooling Technology - Engine Cooling TechWritten by on October 1, 2009 Contributors: John Gibson Understanding & Solving Cooling Problems
Tech Editor John Gibson told me the story of how he was recently at a track in Georgia watching a Street Stock race. During the feature he noticed that several cars would come in under every caution and shoot the radiator with water to cool the engine. Then they would return to the track but wouldn't be able to get their track position back. He said he thought to himself, If these guys had the right radiator and fan they wouldn't have to lose valuable time and positions just trying to keep their engines cool.
In talking with one of these hose-happy Street Stockers after the race, he said that his reasoning for his low-buck radiator was exactly that . . . cost savings. The racer was under the impression that he couldn't afford a "fancy" radiator for his bomber. He didn't recognize the fact that a cracked head thanks to an overheating problem would cost way more than even the nicest double-pass radiator.
John's experience told us that it was time to revisit some critical cooling technology.
So without further ado, let's begin.
Thermal Transfer
Also known as heat exchange, thermal transfer is the very core of a radiator's function (pun intended). Obviously, radiators are designed to protect your engine from overheating by transfering that thermal energy away from fluid that circulates through the engine via the water jacket-a series of passageways cast into the block. As the fluid passes through the hot engine it absorbs the heat, thereby cooling the engine. Once the fluid leaves the engine, it passes through the radiator which is nothing more than a heat exchanger that transfers the heat from the fluid to the air blowing through the radiator.
That thermal transfer is the key to how the radiator functions, but it can only happen when the fluid is in direct contact with the aluminum of the radiator. Manufacturers achieve maximum thermal transfer through several design methods, one major one being by increasing the surface area of the tubing that carries the fluid through the radiator. Typically these tubes are very wide from front to back and slim from top to bottom. Dozens of these thin tubes can be stacked on top of one another leaving small air gaps between them.
Manufacturers will also make the wall of these tubes extremely thin which further increases thermal transfer. Think of it this way: Heat has to pass through the wall of these aluminum tubes away from the water or coolant. The thinner the tube wall, the quicker that process can take place. But that comes with a price since sealing narrow strips of thin-wall aluminum tubing in position can be a tricky proposition. Manufacturers such as C&R Racing have opted to TIG weld them in place and then follow it by furnace brazing, which essentially fuses all of the parts of the radiator together.
Most often these thin-walled tubes are mounted in a parallel arrangement. Separating the tubes are "Z" shaped aluminum fins which help radiate the heat from the tubes. The fins conduct the heat from the tubes and transfer it to the air flowing through the radiator.
In some radiators the tubes will have a type of fin inserted into them called a turbulator, which increases the turbulence of the fluid flowing through the tubes. If the fluid flowed very smoothly through the tubes, only the fluid actually touching the tubes would be cooled directly. The amount of heat transferred to the tubes from the fluid running through them depends on the difference in temperature between the tube and the fluid touching it. So the fluid that is in immediate contact with the tube cools down quicker than the fluid not in contact with the tube and less heat will be transferred. By creating turbulence inside the tube, all of the fluid has the opportunity to come in contact with the tubing wall and lose heat, thereby lowering the temperature of all of the fluid.
Every part of a radiator is designed with the singular purpose of dissipating the heat collected by the water as it flows through the motor. How efficient a radiator accomplishes this task comes down to two specific types of "flow," that being water and air.
Water Flow - Water, or fluid as we have been calling it, flows into a header or large open cavity on one side of the radiator where it then passes through the aluminum tubes before it collects into a header on the other side. This flow of water through your radiator can be influenced a number of ways including through the use of restrictors, the size of the water pump and related pulley system, and the aforementioned inclusion of a turbulator.
Pumps & Pulleys - One of the biggest influences on how efficient your radiator functions is the size of the pulley on the water pump. If the pulley is too big it won't push enough water through the water jacket and radiator to effectively cool the motor. Conversely, if your pulley is too small, water will be pushed through the system so fast it won't have enough time to collect heat from the motor or dissipate that collected heat.
Compounding this problem is the pulley system. Water pumps in many circle track engines are driven off of the crankshaft via a pulley system. If the pulley system doesn't spin the pump fast enough you won't push enough water through the motor/radiator.
Case in point, a friend of the magazine who runs a Dirt Late Model recently had his engine rebuilt. During the rebuild, his engine builder suggested an exotic NASCAR Cup-style pulley system. The builder said the smaller V-belt design of the system would free up horsepower. Now keep in mind that this 550hp motor never had an overheating problem and consistently ran in the 180-190 degree range. It also had a brand-new radiator recently installed. From the first race with the new pulley system, the motor always ran above 220 and would peg the temperature gauge when our racer friend shut it off.
Here's the problem. The smaller pulleys were mismatched to the water pump and ultimately the engine application. They weren't designed for a 5,500-rpm 550hp motor with a stock-style pump and spun the pump too fast, pushing the water too quickly through the cooling system.
Restrictors - In addition to water pumps and pulleys, restrictors are commonly used to regulate the flow of water through the radiator. They're just what their name implies and look like a small funnel engineered to cut down or restrict the flow of water. Usually mounted in the lower radiator hose at the radiator outlet neck, restrictors come in various diameters. Choosing to run a restrictor is a matter of matching it to your system.
"It really depends on the application," says C&R's David Bridges. "With today's water pumps flowing at such high rates, the radiator itself is your biggest restriction and a double-pass is more restrictive than a single-pass."
Bridges says when changing from a double-pass to a single-pass radiator you want to begin with no restriction and then gradually add restriction based on restrictor size until you get the temperatures where you want them. "We always recommend running your water pump at a 1:1 ratio." A 1:1 ratio means that the diameter of your crankshaft pulley is the same as the pulley on the water pump.
Airflow - Like water flow, there are a number of items that affect airflow through the radiator such as fin count, the number of passes, the design of the core, and whether or not it has a shroud.
Cores - Racing radiators come in several different configurations including one-, two-, three-, or four-core/pass systems. This means that once the fluid enters the radiator via the inlet it will make that number of passes through the radiator before it exits back into the engine via the outlet. The most popular short track configurations are one- and two-pass radiators.
In a single-pass radiator the fluid flows through the radiator a single time. A double-pass radiator has two separate sets of tubes, sometimes seperated by a baffle, other times with one set stacked behind another set. Radiators with that second setup are known as a two-core setup. In either case, the fluid flows through one set of tubes and then comes back across the other set, essentially flowing through the radiator twice, hence double-pass. Obviously, in a three-pass there are three separate sets (or cores) of tubes sandwiched together while the four has . . . you guessed it, four cores.
The downside to multi-stack radiators is when you stack cores one behind the other you make it harder and harder for air to flow through the radiator. For bigger tracks and higher speeds, three- and four-pass systems are fine, but they just won't flow enough air to cool your engine efficiently in a 20-lap feature on a flat 1/3-mile track.
Fins - How tightly packed the fins are in your radiator is known as fin count and is measured in fins per inch. A higher fin count means there is more surface area for the aluminum to radiate the heat it absorbs from the water/fluid into the air. However, if the fin count is too high for your application it can actually form a barrier to the air trying to pass through the radiator. When this happens the air stacks up in front of the radiator or moves around it and doesn't reach the cooling tubes in the second row.
As a general rule, a fast race car can use a higher fin count while slower cars should use a lower fin count. If you're racing on tracks between 3/10- to 1/2-mile in length you should look for 14-18 fins per inch.
Shrouds - Regardless of the type of car you race you should have some type of shroud on the radiator. They are easy to fabricate and will maximize your airflow. Shrouds in front of the radiator direct the high pressure incoming air directly to the fins/core. Shrouds between the radiator and mechanical fans help to increase the airflow through the radiator. Sealing the shroud with duct tape is important to prevent any of the air from escaping.
Air Temp Influences - It's not unheard of, and actually probably more common than any of us realize, for the cooling system that worked like a champ in early spring to give up the ghost come mid-July. Here's why: The radiator works the same regardless of the ambient temperature.
"A good rule of thumb is for every 10 degrees increase in the outdoor temperature, the fluid will be 10 degrees warmer in the motor," says Richard Bailey owner of Innovative Cooling Equipment (ICE) of Concord, N.C.
Based on an outside temperature increase from 80 degrees to 105, you will experience a 25-degree increase in fluid temperature in the motor. Take it a step further, let's say your motor typically runs at 220 degrees. Add 25 degrees to that and you're at 245 and in danger of overheating.
That brings us to radiator selection. Your pick of a radiator should be based on the highest temps you'll see during the racing season. However, you must remember that the radiator is just one part of your overall cooling system. That system should be designed and installed not only based on those high outside temps but also on the number of laps you race, the size of your track, and the horsepower of your motor.
When looking for a new radiator, choosing the right number of passes is crucial. Many racers attribute overheating or running hot problems during the summer months to the increased ambient temperatures in June, July, and August. Often the problem rests within a poorly maintained cooling system, a mismatched radiator for your application, or a system that flows the fluid either too quickly or too slowly through the radiator.
So what exactly determines the proper number of passes? What and where you race is probably the biggest factor.
Let's look at John's car as an example. John runs a four-core system from ICE which may sound like overkill but in USAR Pro Cup racing it's almost a neccessity. On a typical weekend John will turn 300-400 laps on tracks 5/8-mile and bigger. A double-pass system would be inadequate for this environment. But the ICE four-pass system keeps the water temperature at an acceptable level even when he runs tape on the nose, a practice asphalt racers use to add aerodynamic downforce to their cars.
Typical short track racers don't need a four-pass system. They will find single- and double-pass systems will work fine for most situations. But which one to choose? There are advantages to both.
Pros & Cons
The advantage to running a single-pass system is that it's about $30 cheaper than a double-pass.
The down side to a single-pass is that it's less restrictive than a double-pass. And that reduced restriction means that the fluid is going to run through the entire cooling system at a quicker rate.
The other down side to a single-pass is that it's not as efficient as a double-pass. Faster flowing air may not have as much time to pick up heat from the tubes. And that's the point of the radiator in the first place, to dissipate heat. Also since the fluid also runs through the radiator a single time, the air passing through only gets one chance to pull heat from the fluid. If the air only "sees" the fluid one time and the air is passing that fluid at a fast rate of speed, it may not be maximizing the heat extraction. But again, much of this depends on the application. Our Project Dirt Late Model has a single-pass C&R radiator that works perfectly on the 3/8-mile dirt track (Ocala Speedway) that we run weekly.
There's virtually no weight savings between a single- or double-pass system because a double-pass radiator is basically a single-pass radiator with a baffle inserted into it that directs the flow of water through the radiator a second time. They're the same size and virtually the same weight. But where the double-pass shines is in its ability to cool your engine.
"A double-pass radiator will increase your cooling efficiency anywhere from 5-10 percent based on the application," says Bridges.
But what about the additional restriction provided by a double-pass? "Today's big water pumps which flow so much more water basically offset the additional restriction you'll find going to a double-pass," says Bridges.
There's another benefit. Say for performance reasons you want to run your motor a little leaner. Any time you lean out the engine, it's going to run warmer; switching to a double-pass gives you that extra needed cooling efficiency at an increased cost of only $30. Finally, the double-pass will move your inlet and outlet hoses to the same side of the radiator, making for a cleaner engine compartment.
The decision of what type of radiator and associated cooling system your race car needs should be based on your series, motor size, and the highest temps you'll see during the summer months.
Wrapping It Up
Ultimately, you need to speak to your engine builder and your chosen radiator manufacturer to ensure that you get the correct cooling system for your race car. Companies like C&R, Afco, ICE, and others are more than happy to help you select the right radiator for your application. However, there are a number of items that you need to pay attention to regardless of the type or make of radiator.
The type of water you're putting into your radiator is important as well. In a passenger vehicle we use anti-freeze, whose active ingredient is Ethylene glycol, nasty stuff. When added to water, anti-freeze drops its freezing point well below the typical 32 degrees F. Obviously race cars don't need anti-freeze, unless you're ice racing in Alaska, but can you do better than just plain tap water?
The problem with tap water, other than the widely varying quality level, is that it often contains minerals, flouride and other particulates, which can corrode the aluminum in your radiator. Both John and Bobby Clark, driver of our Project Dirt Late Model Team use distilled water in their radiators because it's pure, doesn't have any unwanted chemicals, and will ensure optimal performance of your cooling system. Both teams also use a glycol-free additive in that distilled water. Products such as VP's Cool Down, Water Wetter, or 40 Below will reduce cooling system operating temperatures.
One of the smartest things you can do after each race is pull the radiator out of the car and inspect it even if you weren't in an accident. Check all of the lines, hoses and fins. If any of the fins are bent or closed off, air won't pass through them. Take a pair of needle-nose pliers and carefully straighten them out. Hoses that are cracked or in danger of cracking should be replaced immediately. Also pay close attention to the welds for any small cracks or potential breaks. Don't forget to crawl under the car and look on the shop floor. You just might find a small puddle of water that will lead you to a bigger problem.
Choosing the right cooling system for your application and then keeping a close eye on it throughout the season will allow you to avoid problems that would keep you out of Victory Lane.
Radiator Protectors
Radiator protectors are a good way to add an extra layer of protection for your cooling system. These protectors mount in front of the radiator and absorb the impact from debris, rocks, and dirt instead of those aluminum cooling fins. The one pictured above, the Tru-Kool Radiator Protector, is from Speedway Motors. Its Nomex honeycomb construction is very strong and extremely lightweight offering excellent protection.
The protector is disposable and is designed to be replaced as it absorbs various amounts of damage. Naturally, how often you race, the type of track you race on, and other factors will determine how often you have to replace the protector, but some racers have reported running an entire season on just one honeycomb. The Tru-Kool Radiator Protector comes in four different sized sheets that can be easily trimmed to fit any radiator.

�Again, again, we come and go, changed, changing.�
The poetry of Wendell Berry has served many a nature-lover, many a composer and many a music lover. �Circles,� Berry�s poem about the cyclical nature of life, is the title of the final concert of the Durango Women�s Choir this season.
A rare joint performance with the Santa Fe Women�s Ensemble will be staged twice � here and in Santa Fe. The first will be Sunday at St. Mark�s Episcopal Church. The repeat performance will be one week later at Santa Fe�s First Presbyterian Church. Linda Mack Berven and Linda Raney conduct.
It�s pure coincidence that the two directors are both named Linda.
�I�ve known Linda Raney for many years,� Mack Berven said. �It occurred to me that we have the same number of singers and the same repertoire. A year ago, I threw out the idea of an exchange concert, and here we are.�
Each ensemble will sing separately, and the two groups will come together for four pieces, Mack Berven said. They�ll each conduct two.
On either side of the intermission, for example, two settings of �Ave Maria� will be performed� one by Franz Biebl, the other by Gustav Holst.
The program will open with Z. Randall Stroope�s �Magnificat,� a bold setting of the age-old prayer of the Virgin Mary. And the final double-choir work will be a relatively new arrangement of the beloved American folk song �Shenandoah.�
In between, each ensemble will perform spirituals, ballads and folk songs from England, Ireland, Australia and Ecuador. At the heart of the Durango concert will be an unusual work commissioned by yet another Linda for the Durango Choir a year ago.
�A Song of Grace,� by Santa Fe-based composer Linda Rice Beck, has been set to a text by the early 17th-century Metaphysical poet Richard Crashaw. The piece received its world premiere at the Choral Society�s April concert, which the composer attended.
�For a very long time,� Mack Berven said, �the Crashaw poem has been a favorite of mine. There are two parts: A prayer and then an expression of hope for salvation. When I gave it to Linda Beck, she understood the meaning right away. The music is very evocative. It has tension and release in all the right places, and the ending is an ascent.�
The poem will be reprinted in the program, Mack Berven said, because Crashaw may not be as well-known as other English Metaphysical Poets � John Donne, George Herbert and Andrew Marvell. Caught in the throes of the English Civil War, Crashaw, a Catholic, led a precarious life in exile and died at age 36 in Italy.
His poetry is both passionate and contemplative, known for its deep sense of joy and spirituality.
Crashaw�s poetry, Mack Berven added, sets a standard for the texts represented in other selections. Poems by Emily Dickenson, John Keats and William Blake, for example, have been set to music and serve as a basis for the music. �And every work has been composed for women�s voices,� she said.
Wendell Berry�s �Circles� is no exception. When Mack Berven found a setting of Berry�s poem by Texas composer Dede Duson, that completed another circle for her, she said.
The Durango Women�s Choir has been performing for more than 20 years. The Santa Fe Ensemble is celebrating its 31st season.
Both choral organizations have won Choral America�s Alice Parker Award for Adventurous Programming.

Guest column/Month acknowledges contributions of African-Americans
February 3, 2013
Once again, we have embarked upon one more year of commemoration of Black History Month....
Yes sir..I new that word racist would pop up..racist is so watered down that it just means nothing anymore...i am far from a racist. the ones that hollar racist the loudest are the real racists..you are celebrating black history month, what about the black panthers, the drug dealers, the street gangs, the black on black murders..lets tell the whole story not a sugar coated one. A people who carry hate in their hearts because of what was done in past history and not done to them..all nationalities have had bad things happen to genertions before them...look at the holicost victims...Go to God and ask him to take the hate from your hearts and live as americans, quit putting up deviding walls.

God blesses this nation every day the sun comes up and you are given a new chance to lend a hand and share the good news. Subtle hatred and bigotry still smells the same as full on racism, especially after its lets to fester and ferment a while. Your view of history dorf, seems to be a little one sided.

one thing that seems to be missed in the african american history is that the black man was the first to have black slaves in Lousiana. I am tired of reading the words "African Americans" are you not "Americans" were you not born on american soil? that would make you an american...you fought for segregation and you got it...why is there NAACP, Miss BLACK America, BET t.v. and on and on? God will only bless this nation when we come together as a people without division!

Having thought more about this. I decided that based on the Yiddish meaning of Bentching, everyone who is old enough to say Asher Yatzar does. Because you wash and then bentch Asher Yatzar. I am leaving my original answer as well.
Everyone who follows the rulings of the Ben Ish Hai who says to wash ones hands and make a Berakha on besamim before each of the three prayer services(actual source in sefer Ben Ish Hai, and its derivative from Sha'ar HaKavvanot to follow once I look them up).
The Kohanim by Birchas Kohanim
Does drinking count as eating? There is certainly an opinion that one bentches birkat hamazon after wine, and I think there is an opinion to wash before wine, certainly terumah in days of bais hamikdash

Having a good business and a website for it is no longer enough for it to be successful and productive enough in this day and age. SEO efforts are normally required so that a business is exposed out there to as many potential customers as possible. This is what we call being smart and consistent, rather than being strong and resourceful. It helps your website to improve ranking on search engines, increase chances of viewership, which may translate to increase of traffic into your site, as taught by the guys at OMG Machines.
An increase of visitors to your site is more likely to result to an increase of products and services for your business, which goes without saying that profitability is more likely to increase. You can't fail to imagine how the growth of your business will be aggressive, and how your brand will be promoted. However, even as you have your website performed SEO on; there are some other channels that you can use to boost these efforts, promoting your business even more. Here are some tips that you can use to achieve the same, some of which you have to consider even before your website is set up and running.
The choice of your domain name matters
When setting up a website for your business, ensure to come up with a relevant, simple, and clear domain name. It should be a name that is easily memorable and suggestive. Being suggestive here would mean that a person is easy to tell what the site is all about by looking at the domain name. If a domain name has keywords in it, it is more likely to be easily identified by search engines than one that lacks some. The domain name should also be kept short and enticing if you can manage. This is one area that requires the most out of your creativity. You can see this with the OMG Machines SEO tutorials and reviews.
This along with other internet marketing strategies can go a long way in reaching out to the better fraction of audience in your target market.
High quality and keyword rich content
One of the most important keys to your online marketing success and SEO efforts is your content, especially the written content. From your homepage, to successive pages and other material such as articles should be design in a way that is influential, clear, eye catching as well as keyword rich. When it is eye catching enough, the content will most likely be able to win more viewers from internet users that happen to land on your site, from wherever source such as search engine results. On the other hand, search engines are nowadays smart enough to tell the difference between quality content and that which is not. In the titles, body, and conclusions if any, important and influential keywords should strategically be used to target the interest of search engines.
It is thus essential to conduct a good background research on what your target audience has been searching for over the internet and use it to your advantage. Material should be relevant, consistent, up to date and creative enough.
Have you tried SEO tools and applications?
A good SEO approach is one that where a good research has been conducted prior to putting in efforts. Reliable software applications exist, which can assist you with tasks such as keyword research, niche selection, among others. A few of them are listed below.
- SE spider simulators.
- Domain name checkers.
- Niche selection applications tools.
- Keyword finders.

Social media marketing and video marketing
In this day, a better fraction of the world's population not only has access to the internet, but also accesses their social media accounts regularly. As a matter of fact, there are those people who only use the internet to access social media platforms such as facebook, twitter, instagram and others. This is quite a good market to tap into. You can effectively boost your SEO efforts by establishing campaigns on these platforms as well as advertizing your products and services as well as your blogs and main sites.
In current times too, video content continues to take over the internet audience by storm. A trend to market products and services has long been there since the invention of the TV, only this time it has become more digital and influential too in the online marketing arena. Having a YouTube channel from which you promote your products and services can be a great idea for an approach to boost your SEO marketing efforts.

What is $ \displaystyle\int_0^1 \frac{\ln(1+bx)}{1+x} dx $?
I call it $f(b)$ and differentiate with respect to be $b,$ a bit of partial fractions and the $x$ integral can be done. Then I integrate with respect to $b$ and get a bit lost.
Can some of the terms be expressed in terms of dilogarithms? I get lost in the details! Could we avoid all this just go straight to dilogarithms (with a cunning substitution)?

Kids and Secondhand Smoke
Q: My young children come with me when I care for someone else's children in her home. Both this woman and her husband smoke a lot. Can exposing my children to this for a short time be harmful to them? Can just the smell be harmful?
A: Environmental tobacco smoke (ETS) is the smoke in the air -- for example, the smoke that streams off the end of a burning cigarette, cigar, pipe, or even the smoke that is breathed out by an individual. The strong smell you are noticing is probably a combination of these, and it is potentially harmful. Although you and your children are only directly around the couple for a short time, the smoke can remain in the air after the couple leaves, exposing everyone.
Many people have opinions about "second-hand" smoke exposure. My personal thoughts are that any amount of ETS can be dangerous for children, so I would encourage you to keep your children away from it as best you can. Although your children may be around these smokers for only a relatively short amount of time, it is likely that they are also being exposed elsewhere, such as restaurants, malls, and other public areas. Every time you and your children are around people who smoke, the opportunity exists that you may be breathing in the potentially irritating chemicals found in smoke.
Children who are exposed to ETS are at higher risk for some diseases or the worsening of current medical conditions, such as ear infections, hearing problems, and breathing problems like colds, asthma, and lung infections. Immediate effects of smoke exposure may include nausea, dizziness, and headaches; long term risks include lung cancer, heart disease, and cataracts.
Given these risks, children should avoid ETS exposure as best as possible. Perhaps the couple will agree to smoke outside before and after you and your children arrive. It is important that you ask the couple not to smoke when you and your children are in the house or around the times you are expected to be there. I hope they will understand and respect that you are trying to protect the health and well-being of you and your children.

וְשָׁם יָנוּחוּ יְגִיעֵי כֹחַ
What does the word שָׁם refer to in יוֹם שַׁבָּתוֹן and where will the יְגִיעֵי כֹחַ rest?
What does the word שָׁם refer to in יוֹם שַׁבָּתוֹן and where will the יְגִיעֵי כֹחַ rest?
From the Ya'avetz: Noah sent the Yonah (dove?) the seventh day which was Shabath and it finally found a place to rest. In addition Knesset Yisrael which is meshula (analogic to? symbolized by?) the yonah will find rest in Shabatah. In addition the Gehenom so-called is "closed" in Shabath so the reshayim have a day of rest. My addition: Sham which generally means a place is here used in the sense of a "place in time" .
This fragment is actually a quotation from Sefer Iyov (3:17):
In the original pasuk, the reference is to death (or the grave; but same idea).
In the song, "Sham" refers to Shabbat itself.
I would suggest that the context of the quotation lends itself to (as in Rony's answer) the wicked resting from Gehinnom on Shabbat, and a hint of the final stage of creation, the eternal shabbat:
