Can someone recommend some good headphone/earphones for airplane travel for under $50?
I'm going to have to make several flights in the next few months and my crappy headphones just won't cut it any more. I want to be able to discern song lyrics and movie dialog from my HTC G2 phone. Of course, money is a factor as well, so who can recommend some good noise-reducing headphones or earphones for under $50? I'd prefer over-the-ear but if some in-ear models get good reviews for comfort I'll consider them. THANKS!
11 Answers answer
Okay, first off, I know you said $50, but Sony makes some really great over-the-ear headphones that are awesome (sold for $65 on Amazon: here)
They're really durable and will last you forever if you are even the slightest bit careful with your stuff. Also, Sony has made these headphones for about 30 years now, so if you ever need a replacement earpiece (the vinyl/foam surround), you know they'll be available.
However, if you're set on getting some under $50, then you could get these. They won't be quite as nice, but they're nothing to shrug at.
Assuming the goal is to block outside noise (i.e., deafening drone of the engines), you have two general options - active noise cancelling and passive noise cancelling. Active means the headphones have a power source and generate complementary noise to cancel out exterior noise. Passive means the headphones physically block external sound in generally one of two fashions - circumaural earcups or in ear monitors. Circumaural means "around the ears" as contrasted to supra-aural or "on the ears". Circumaural phones accomplish noise blocking by providing a tight seal between the head and earcup and by having a closed back design which means the drivers are in an enclosure open only to the ear, not to the outside. In ear monitors (commonly IEMs or canalphones) are roughly earplugs with tiny speakers in them.
Sorry for the definitions, but those terms honestly help in searching for headphones, and knowing what they mean can help you narrow your choices.
I don't have experience with active noise cancelling phones, but common complaints are fatigue related to the added noise and battery requirements. Some ANC phones do not work as standard headphones if they lose power.
Circumaural headphones often clamp too tightly to achieve a good seal and lead to fatigue due to the pressure.
My preference is IEMs, but they don't work for everyone. Most include a number of silicone or foam tips to fit a range of ears, and finding one that seals well without being too tight can be challenging. Note that the tips are pretty standard and if you find some that work, you may be able to use them on another set of IEMs.
What works for you will likely come down to personal preference, but you should really be considering one of these three types.
And I use Panasonic RP-HJE270 which I believe are now discontinued. Head-Fi has a ton of "headphone list" forum posts (like this IEM roundup and this general list). Sorry for not having one magic suggestion.
I'm not an audiophile, I won't be able to tell you why headphones are better or worse than their conterparts, but I can tell you I'm happy with these:
I travel a lot, and when I have these on whilst flying, I can't hear background noise, only music.
@mattschuette: I agree with Matt. In-ear monitors are also my preference for in-flight listening. They are much more comfortable for long-term wearing (the well designed ones) and you don't have the bulk on your head, so you can move around. It's an ergonomic choice.
You said $50; and I am an audiophile (wrote for a major magazine back in the days even).
At this price, you can try the Sennheisser CX200 (and a plug for my buds at Amazon: http://ow.ly/6OvlX) - $39. Now, since you have money left, I would HIGHLY suggest the Comply Foam replacement foam tips. Swap out the rubber flanges with these memory foam tips, the noise level would dramatically go down; and since the foam conforms to your ear's inner tube, it's more secure and way more comfortable. http://www.complyfoam.com/.
That adds up to just around $50. Hope this helps!
For my personal use: Etymotic ER4 with a lithium battery powered headphone amplifier that I designed (putting the EE degrees to work). About ~$500.
Not an audiophile. The best buds I have bought have been the Skullcandy Ink'd for around $10. They are more user friendly for those of us with smaller ears and cancel out, for me anyway, at least 80% of the noise. Paying $50+ for something that the cat may chew, I may lose etc..is not an option on my budget.
I love my Klipsch Image S4s. They sometimes go on sale for around your asking price.
I enjoy my WeSC headphones
They look pretty sick, have good sound quality, and are not that expensive.
I have a pair of the Oboes and Congas (enjoy the Congas slightly more though)
I bought some Able Planet active noise cancelling cans on woot some months back for $49 - I think they're regularly around $100. A GREAT deal. The noise cancellation is VERY good. They are also quite comfortable The sound quality is not as good, but a media player with decent equalization controls can compensate. For commercial air travel - I HIGHLY recommend ANC phones. I could not go back.

5 Idiotic Space Travel Ideas (That Might Actually Work)
This whole space travel thing has gotten pretty boring ever since we landed on the moon. We can't make it to another planet and none of our ships have lasers. What the hell is the point?
But there were some incredibly awesome technologies that never made it off the drawing board. All because we didn't have the foresight, there wasn't enough funding, and they sounded like they were made up by a kindergartner.
#5. The Gigantic Space Cannon
Gerald Bull was a physics genius, and without a doubt the greatest weapons designer that Canada has ever produced, which may very well be impressive for all we know of Canadian weapon designers. Bull's line of work was a field called "super-artillery", which is a military term meaning "huge fucking cannons."
One of his crowning achievements was the G5 Howitzer, which could launch a shell 30 miles. Being the sort of person who gets a Physics PhD and goes into the field of "giant gun design," Bull decided 30 miles was fucking embarrassing.
So he went to work with the American government in the High Altitude Research Project, where he pointed other gigantic guns directly up into the sky and fired objects up to 60 miles high. You know the Stratosphere? Bull shot through that shit, sending projectiles into something called the Mesosphere. But that wasn't enough. His dream was to build a cannon so big it could shoot a satellite into orbit. After all, isn't that how they'd do it in a cartoon?
Above: Gerald Bull
After trying the Americans, who shockingly turned down the opportunity to build a ludicrously huge cannon, he went about building and selling arms to crazed dictators from all over the world, including South Africa, China, and Iraq. He eventually convinced budding young Iraqi leader Saddam Hussein that the only way to make all the cool countries respect him was to have a space program built around his big-ass cannon.
Saddam put him to work building his dream. They made a small scale prototype to work out the kinks, and there were probably several considering the final gun (nicknamed Big Babylon) was to be 500 feet long and 3 feet wide. It would have to be built into a freaking hill, just to stand up.
So Why Don't We Have One?
Before they could import the materials for Big Babylon, Hussein decided to invade Kuwait, and brought down the wrath of the international community.
It turns out part of Iraq's strategy in the Gulf War consisted of shooting at the Israelis. Israel wound up sending the Mossad (they're sort of like the CIA only they're actually good at what they do) after Iraq's weapon suppliers. Shortly thereafter, Bull was found dead in his apartment with 5 bullets in his head.
And thus, another of the world's dreamers died, taking his dreams with him. Just as John Lennon wanted world peace, Gerald Bull simply wanted a gun big enough to fire shit into space.
#4. The Atom Bomb-Powered Spacecraft
Even when space travel was still on the drawing board, mankind was full of visions of missions to Mars and space hotels. We saw with sinking disappointment that people could only go up in tiny little capsules with stale air, cramped quarters, and crappy food, and even then only after decades of training.
But there was a pair of crazy bastards named Ted Taylor and Freeman Dyson who headed a project to build a huge, sci-fi atomic spacecraft. And no, we don't mean that it worked on atomic power (though NASA tried to do that, too, with a project called NERVA). We're talking about something way, way more awesome than that.
Freeman Dyson totally doesn't look crazy or anything.
Their idea was a mammoth spaceship weighing up to 7 million tons that ran on nuclear bombs. Yes, nuclear bombs. As in, you take a huge spaceship, and stick a fucking nuke under it, then set it off. These guys would have taken one look at the giant gun guy and laughed in his face.
So the ship gets flung into the atmosphere by the nuclear explosion that just happened under it. Then what? It's going to start slowing down eventually, right? Well, you drop another nuke out of the concave (and heavily armored) bottom of the ship, and detonate it when it gets about 200 feet away. Rinse and repeat until you're in orbit. What could possibly go wrong?
Oddly enough, the lift-off would actually be smoother than any shuttle liftoff because the sheer mass of the enormous vehicle would almost completely eliminate turbulence. Initial tests were conducted with C4 and determined that the project was not only feasible, but actually exceeded expectations.
So Why Don't We Have One?
First, a bunch of party-pooping anti-nuclear types got a hold of it and started on with their "fallout" this and "environmental catastrophe" that. Then when the 1963 Treaty banning upper atmospheric nuclear detonation was signed it basically gave the project the kiss of death.
That's right, it took a Treaty to convince people that a nuclear-bomb-shitting space city was a bad idea.
#3. Buzz Aldrin's Martian Gravity Express
After Nixon started the 1970s fad of slashing NASA's budget whenever they asked for money, it became something of a government tradition. To try to deal with having craptastic funding, NASA veteran Buzz Aldrin came up with a clever idea to save money going to Mars: Don't use any fuel.
Instead of actually powering the ship, he suggested you use Earth's gravity like a slingshot, shooting it into mars' gravitation field, which then would sling it back at earth. It would theoretically continue with this gravitational slingshottery until the end of time, using almost no fuel, and allowing them to load it up with equipment and personnel in a detachable cargo ship to drop every time it got close to Mars.
Above: Cracked's childlike grasp on this complex concept.
Also, you would get two going in opposite directions, because the way the gravity system works out, the trip there is nice and speedy, but the trip back takes a while. This way one of the ships would spend the short trip going Mars to earth, and the other would be earth to mars. No problem!
So Why Don't We Have One?
The long end of the trip takes about 21 months. At about this point the guys at NASA stopped listening, because who the hell wants to wait two years to be able to send another shuttle?
This also means the departure times are non-negotiable. Still working out the kinks on your little Mars rover? Too bad, the bus is leaving! Better luck next time, assholes!

Well, it finally happened. After running out of steam on my last thread (largely due to a little self loathing of being at such a big club) I've eventually decided on a new destination for my latest FM adventure.
My FM destinations are normally quite predictable. I've always liked the idea of taking a small club up from the bottom and establishing themselves as a force, normally in England, or every now and then in Italy. I decided it was time to move completely out of my comfort zone, somewhere I've never set foot in, somewhere with a completely different football culture to immerse myself in. Therefore, I've packed my bags and left dear old Blighty for the sights and sounds of South America.
I'm not going to set myself any goals at all in this career, just aim to start at the bottom somewhere and see where it gets me. I'm pleased to see there aren't too many South American based careers on here, so I'll be walking pretty much blind. Always the best way to go...
Anyway, the details:
FM11.3 with no edits
Leagues loaded from Argentina (Second Division and above) Brazil (Third Division and above) Columbia (Second Division and above) Chile (First Division B and above) Uruguay (Second Division and above) Peru, USA and Mexico (Promotion League) For good measure I've also added England, Portugal and Italy, although they're simply to ensure the reality of the better players in South America getting picked up by big European clubs happens, but are largely unimportant to me.
48,000 players, medium database
Oh, and to make things more interesting I'm going to pick my club with the random button. Really do love that button!

How Rude! An Age-by-Age Guide to Teaching Kids Manners
4 of 10
Ages 3-6: Making Introductions
This one can be tricky, especially if your child is shy around strangers. But learning to introduce himself at a young age is an impressive social skill that might help him make new friends. Here's how:
- Practice shaking hands and saying "Hi, my name is..." at home with his siblings or even dolls or toys so that she gets used to the idea.
- Teach him more introduction etiquette, such as whether to call someone Mr. or Mrs., and how to be nice when older family members want to hug or kiss him.

6 Disturbing Unanswered Questions from Children's Movies
It's hard to find a children's movie made in the last couple of decades that doesn't have a happy ending, usually to the tune of a pop song. It's part of the formula, along with talking animals, celebrity voices and pop culture references no 10-year-old could possibly understand. Now it's all jokes and dancing. What happened to all the sadness and horror that used to traumatize children in the '80s? Where did we go wrong?
Fortunately, the traumatizing moments are still there, just better hidden. While the protagonists are learning important lessons and living happily ever after, some overlooked characters end up suffering fates that are often worse than death. Listen up, kids, because in ...
#6. Monsters, Inc. -- Did the Little Girl's Parents Think She Was Kidnapped?
Pixar's Monsters, Inc. is about a place powered entirely by the screams of little children, much like Disney World itself. The monsters living in this Monstropolis are currently in the middle of a scream shortage, so the corrupt CEO of the one company that runs everything secretly plans to kidnap kids from the human world and strap them to a machine in order to harvest their fear more efficiently.
"Let's just kill her parents in front of her. She'll be screwed up for years."
The first lucky kid to get this honor is Boo, a little girl who slips into the monsters' world during an implied kidnapping attempt and befriends a giant blue beast named Sully and a one-eyed atrocity called Mike. After about a day of shenanigans, Mike and Sully uncover the conspiracy and finally manage to get Boo back into her own bed, and she resumes her life as if nothing happened. Everyone lives happily ever after!
They Forgot to Mention ...
Wait a minute, Boo was gone from her home for "about a day"? Unless she had extremely absentminded parents, that means her greatest adventure was also her family's worst nightmare.
We saw Boo spend a whole night at Mike and Sully's, and by the time they returned her home it was night again, so she was in Monstropolis for at least 24 hours. Exactly what kind of hell were her parents going through at the same time? There was probably a Caylee Anthony style media frenzy going on in the real world while she was off having fun with her new friends.
Via Fanpop.com
There's a thin line between "adventure" and "Amber Alert."
We know what you're thinking: What if time flows differently in Monstropolis, like it does in Narnia? Well, first of all, you are a huge nerd for knowing that about Narnia, and secondly, no, it doesn't, because at one point Mike and Sully are exiled to the real world, where they meet the Abominable Snowman, as voiced by Cliff from Cheers.
If you just assume a Pixar character is voiced by John Ratzenberger, there's a 20 percent chance you'll be correct.
If time flowed more slowly in Monstropolis (slow enough that an entire day there was just a few hours for Boo's parents), by the time Sully trekked to the nearest town, sneaked into a house and used the closest to go back to Monstropolis, Boo would have been strapped to the machine for a long time and unable to do anything but scream.
"Here's your kid back. We ... 'cured' her hyperactivity problem."
If there's any consolation for Boo's anguished parents, it's that she isn't old enough to talk and can't tell them she spent her missing day with a big hairy man who made her dress up in weird costumes.
#5. The Incredibles -- Why Didn't the Government Tell the Family They Were in Mortal Danger?
The Incredibles is set in a world where superheroes have been forced to retire by the government, until they are brought back into action by a vast conspiracy that's killing them off -- it's essentially Watchmen, except with less gratuitous nudity.
In the movie, the government keeps tabs on all superheroes through the National Supers Agency, forcing them to stay in their lame secret identities. Former superhero Mr. Incredible, currently an insurance salesman, gets the chance to relive his glory days when someone recruits him to take out a rogue robot on a tropical island. However, the whole thing turns out to be a plot by the villain Syndrome. In fact, we learn that Syndrome has successfully killed several other superheroes that he lured to the island under similar pretenses:
The movie then shows a 45-minute scene of their slow disembowelment while they scream for their lives.
Mr. Incredible is eventually rescued by his superpowered family, and then Syndrome's cape gets caught in an airplane turbine and his body is torn to pieces in another perfectly happy Pixar ending.
They Forgot to Mention ...
Hold on, if the National Supers Agency is so good at keeping track of superheroes ... how come nobody noticed they were being killed off? Dozens of them. Wasn't this, like, their one job?
"Well, if we report them dead, we don't get paid to watch them, do we?"
When Mr. Incredible sneaks into Syndrome's hideout, we learn that the first six versions of his robot had killed 15 superheroes, leaving their corpses scattered across the island. And by the end of the movie, Syndrome is up to his 10th robot, each version more efficient at superhero-killing than the one before. The total body count may be somewhere around 30, which, holy shit, is more dead superheroes than in Watchmen and The Dark Knight Returns combined.
So apparently, the government either failed to notice that the people they were keeping tabs on were suddenly disappearing (which is unlikely) or didn't give a shit. When Mr. Incredible's identity is compromised for the umpteenth time, his government liaison Rick Dicker doesn't even think to mention the fact that Mr. Incredible and his family may be in immediate mortal danger. Instead, he complains about how much money it would cost to relocate his family again and tells him, "You're on your own from now on."
And he was even at their wedding!
Assuming that every registered superhero had their own liaison like Rick Dicker, what were the other ones doing this whole time? Besides enjoying a lighter workload, that is.
#4. The Iron Giant -- What Happens When the Rest of the World-Destroying Giants Show Up?
The Iron Giant follows the friendship between a 10-year-old boy and giant amnesiac robot from outer space who is currently being hunted by government agencies, since they view him as some kind of secret doomsday weapon. As it turns out, he actually is a secret doomsday weapon -- as soon as he gets his memory back, the lovable 50-foot-tall steel monster turns into a terrifying 50-foot-tall steel monster.
In a subsequent shot, speakers emerge from his back, blaring NWA's "Fuck tha Police."
Eventually, the boy convinces the robot that full on murder mode isn't the best way to make friends, and the robot ends up sacrificing himself to save an entire town in a heroic, tear-jerking final scene. However, in the epilogue, we see the scattered pieces reassembling and repairing themselves out in the wilderness, promising us that the robot will eventually come back to life.
They Forgot to Mention ...
If that ending made you feel good, you got it all wrong. And here's why.
We've previously pointed out that if there was a sequel to The Iron Giant it would have to deal with the fact that someone had to send this robotic weapon thing to Earth (a small detail the movie never acknowledges), and they probably aren't gonna give up after one failed attempt. What we didn't mention is that there couldn't be a third movie after that, because by end of the second one the whole world would look like this:
That's a burning city in the background, with an army of iron giants marching in the foreground.
That's from a deleted scene in The Iron Giant, which shows the robot's memory of what he and other robots did to another planet. Not only do we get a confirmation that there's an army of these things out there, but also that they don't just conquer planets and enslave their inhabitants -- they actually punch them until they explode.
And there must be a shitload more of them, because they were pretty willing to sacrifice the ones on the surface.
Also, as the final scene points out, they can survive nuclear blasts. The only one who could fight them is the Iron Giant himself ... but who says he's still friendly after rebuilding himself? For all we know, when those eyes lit up at the very end of the movie, the one thought in his head was "DEATH TO HUMANS."
"I long for the abbreviated screams of children."
If a bump to the head was enough to erase his memory at the beginning, we'd say a nuclear blast can do the trick as well. Sure, the boy could probably convince him to be friendly again, but he's in freaking Iceland when we last see him -- by the time his path of destruction reaches the boy's town, half the country would be in flames.

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.
I could probably come up with 2 pages of humor here, but I'll assume you are taking this seriously. So, I'll respond as seriously as I can.
First thing you must understand: @Craig is right... differnet organizations mean different things. For some, it's just part of their advancement track and doesn't really mean much beyond that. For others, its a distinct role and very often, they get subverted out of doing any code or other hands on work and so lose their efficiency.
The point at which you stop being a developer and start being an architect is the point at which you spend 90%+ of your time engaged in the following
Short of it is that an architect is the interface between the dev team and the stakeholders (the BA is the opposite). They need to be able to understand the business side and the technical details, but truth is, they are likely to not "get their hands dirty" all that often. Their primary 'technical' skills need to be with UML, a word processor, other technical drawing tools, and presentation software. So, in most cases, within a few years, they will start to become less and less effective as their knowledge of coding becomes dated (e.g. they are trying to think in C++ while the project is in C# or Java). At that point, the smart people learn how to lean on and learn from the hands on folks. The others become a pain in rear because they have a harder and harder time relating to state of the art.
I think there is no best answer than:
So if you do architecture, you are an architect. Maybe you asked for what is a "good" architect ? Or maybe a predefined task list?
In addition to the other excellent answers, including the one from Jim Leonardo, please read this document:
Who needs an architect - Martin Fowler
My opinion ?
Although it is true that software architects "do architecture", I think the role today has come to mean much more. Someone in the "software architect" role tends to be a leader, both in skill and in status.
I've always liked Ted Neward's definition of a software architect:
And later on:
Unfortunately, not everyone who carries the title "software architect" fits this definition. Others fit the definition but don't carry the title. Nonetheless, I feel this is a more accurate definition of the modern software architect. If nothing else, it is a worthy goal to strive towards.
Like most IT job titles there is no definition, it is just a made up term. I would describe a Software Architect as someone who is in charge of the technical application design, building things like base libraries, application frameworks etc. Of all the various IT 'Architecture' jobs this is probably the lowest one on the food chain.
A guy whose coding skills are terribly out of date, but who is not capable of performing any managerial duties.
An impractical fool with an over-inflated sense of self-importance who destroys whatever thing he touches, never ceasing to bring layers of accidental complexity to even the simplest of contrivances, but who is, thankfully, kept out of harm's way by being assigned the task of writing grandiose-titled corporate documents that no one is ever expected to read.

A Contribution A Day To Keep Regulators At Bay?
by Anne Bauer, April 20, 2010
Executives of health insurance titans WellPoint, UnitedHealth Group, Humana, and Aetna were called before Congress in March to explain stiff rate increases and claims denials. Despite the publicized wrangling at the federal level, state governments actually bear primary responsibility for health insurance regulation--and that has not escaped the notice of health insurers. These four companies were major players in state politics, giving a total of $8.7 million to candidates and committees in 42 states from 2005 through 2008.

Steinberg EE, Keiflin R, Boivin JR, Witten IB, Deisseroth K, Janak PH. A causal link between prediction errors, dopamine neurons and learning. Nat Neurosci. 2013 May 26 ; Pubmed Abstract
Researchers across our field (even those relatively less interested in the brain) are deeply concerned with causalityfrom those geneticists or epidemiologists assessing the relationships between genes or cannabis exposure and illness onset to those phenomenologists concerned with how patients describe their thoughts and actions as lacking causal agency. For the most part, all of our observations are correlational. Anything more causal, with a few exceptions (Corlett et al., 2009), would entail ethical concerns. Causality is particularly problematic for those of us concerned with the neuronal mechanisms of symptom generation. Are the neural signals we observe with functional neuroimaging of patients with psychotic symptoms, for example, a cause of those symptoms or a consequence of having distressing and distracting experiences in the scanner?
In a 1979 issue of Scientific American, Francis Crick (of DNA fame) wished for a method to gain control over some neurons whilst "leaving the others more or less unaltered" (Crick, 1979). If we can recreate a pattern of firing that is thought to be necessary and sufficient for a particular cognitive process, we can be more certain that that particular signal is causing that process.
One increasingly influential model of delusion formationthe aberrant prediction error account (Corlett et al., 2007; Gray et al., 1991; Hemsley, 1994)recently received a preclinical boost in this regard. Using optogenetic techniques (see below), Steinberg, Janak, and colleagues demonstrated that a specific pattern of neural firing, prediction error, at a particular time (coincident with irrelevant cues), was causally related to behavioral learning (about those irrelevant, predictively redundant cues) (Steinberg et al., 2013). This is exactly the pattern of neural signaling and behavior that portends delusions, according to the theory (Corlett et al., 2007; Gray et al., 1991; Hemsley, 1994). Prediction errors and delusions have been associated previously with correlative studies (Corlett et al., 2007; Romaniuk et al., 2010; Schlagenhauf et al., 2009). These new data show that, if one engenders prediction errors artificially, aberrant learning results.
Steinberg, Janak, and their colleagues achieved this feat by first identifying a cell population of interestdopamine cells in the midbrain previously implicated in the pathophysiology of schizophrenia (Carlsson and Carlsson, 1990). Next, they chose a firing patternphasic firingwhich has been correlated with Pavlovian and instrumental learning in now classical, albeit correlative, work from Wolfram Schultz (Schultz and Dickinson, 2000; Tobler et al., 2006; Waelti et al., 2001). Finally, they homed in on an informative behavioral paradigmblocking.
Blocking calls into question Hebbs adage that in learning, things that fire together wire together (Hebb, 1949). We do, of course, learn from contiguity and statistical regularity, but blocking teaches us that there is more to learning than mere correlation (McLaren and Dickinson, 1990). In a blocking paradigm, we first train a cue (such as a light) as a predictor of a salient outcome (such as a food reward). Next, we add a novel cue (such as a tone) to the first cue. This compound of cues (tone and light together) also predicts the outcome. Prior learning about the first cue blocks learning about the second cue (Kamin, 1969). That is, despite being contiguous with the outcome, an association between the second, blocked cue is not learned. This is because the outcome was already predicted.
Blocking led to the invention of learning theories that focus on prediction errorthe mismatch between what we expect (based on what we have already learned) and what we experience (Rescorla and Wagner, 1972). We learn most when prediction errors are largest, and we dont learn when there is no prediction error, as in the blocking case. Prediction errors have been implicated in the formation of causal beliefsassociations between cause and effect (Dickinson, 2001; Fletcher and Henson, 2001)in social inferences, such as attributions of worker productivity (Cramer et al., 2002) and in the formation of trusting relationships (Behrens et al., 2008). Furthermore, aberrant prediction errorssignaled independent of cue and contexthave been associated with delusion formation in psychotic illnesses (Corlett et al., 2007; Romaniuk et al., 2010; Schlagenhauf et al., 2009) and model psychoses such as amphetamine and ketamine administration in human subjects (Bernacer et al., 2013; Corlett et al., 2006).
However, all of these important observations lack a definitive demonstration of causal association between prediction error, learning, belief, reputation, trust, or delusion. Janak, Steinberg, and their colleagues provide some of the first evidence for a causal association among prediction error, dopamine firing, and learning.
They made an elegant genetic manipulation in rats. First, they targeted dopamine neurons specifically by driving Cre recombinase expression with a tyrosine hydroxylase promoter. Tyrosine hydroxylase is an enzyme that is crucial in the production of dopamine and is present in dopamine cells. Cre recombinase subsequently triggered the expression of an ion channel that is sensitive to lightwhen this channel is stimulated with light of a particular wavelength, the channel opens and the cells expressing the channel depolarize and fire action potentials. The genetic technique colocalizes the channel and the dopamine. The targeted application of light (hence, optogenetic) ensures specificity to cells that have previously shown prediction error-like signaling. Steinberg et al. applied the light following blocking trials (when there should be no prediction errorconfirmed with neural recordings in monkeys and with fMRI in humans; see Tobler et al., 2006; Waelti et al., 2001). The causal proof comes if the rats learned about the blocked cue. They did. They formed a predictive association between the blocked cue and the reward.
Intriguingly, this is exactly what we think happens in patients with psychotic illness. Their prediction error signaling neurons are inappropriately activated, driving them to attend to and learn about things they ought not to, things that non-psychotic people would ignore. This is the kernel for delusion formation. Paul Fletcher and I recently showed that in non-psychotic individuals with odd beliefs (such as telekinesis or alien abduction), there are prediction error brain signals during blocking, and the magnitude of these signals correlates with weaker blocking and with the severity of odd beliefs (Corlett and Fletcher, 2012).
Whilst it is heartening to have our theories supported by preclinical data, what might be the clinical application of this new result? We cannot make optogenetic manipulations in human subjects. However, we can make manipulations of cortical neural activity using transcranial magnetic stimulation. Such studies are underway in my lab at Yale. We are using stimulation protocols that engender neural inhibition and long-term depression (Hoffman and Cavus, 2002) in an attempt to cancel aberrant prediction errors in psychotic patients. The data of Steinberg et al. suggest that this approach might ultimately help us to control prediction error signaling and curtail psychotic symptoms.

Primary Papers: A causal link between prediction errors, dopamine neurons and learning.
Comment by: Anna Ermakova

Posted 22 July 2013
Highly replicated correlational studies, beginning with electrophysiological recordings in primates and rodents and followed up with similar studies using PET and MRI in humans, established a strong correlation between dopamine neuronal firing and learning about rewards. This process appeared driven by the mismatch between expected and actual outcome, called prediction error. Steinberg et.al. in their recent article take a crucial next step into the interactions among prediction errors, dopamine, and reinforcement learning: They demonstrate a causal link between phasic dopamine prediction error signaling in the midbrain and learning stimulus-reward associations. In their elegant experiments they used two classical learning paradigms: associative blocking and extinction. They mimicked prediction error signaling by inducing precisely timed dopamine firing with optogenetics to slow down extinction and to drive learning. This is an important first step for moving away from correlational studies to direct manipulation, and I am sure it will be followed by many others to advance understanding of the precise neural mechanisms of reinforcement learning in health and disease.

I have recently changed from Ubuntu to Xubuntu and had always mounted my Windows partition automatically to /media/Windows. When I do the same thing in Xubuntu, it does mount it correctly, but it doesn't show the link to the partition on my desktop.
I now that I could just set a link to the directory, but that's just not suitable for me. I want to now why Xfce doesn't show additional automatically mounted partitions on my desktop just like in Ubuntu/Unity. The / system and not-auto-mounted partitions are shown as usual.

I have more than 20 filters, how can I easily reorder them?
GMail natively does not have this feature. However, there is a Filter Import/Export feature in the labs that you could use, though it involves editing xml.
Once you enable the feature and Save Changes, go to Settings > Filters.
This will result in an xml file. You could edit the xml file to move the order of the filters, and then reverse the process and import them.
Any time you save a filter, it goes to the bottom of the list. Once you know what order you want your filters in, open each one in order, and just click Save without changing anything. When you get to the last one, the filters are all in order.
Of course, you would have to repeat this if you ever really did have to change a filter.

If I am using a large Javascript library for my page, how can I make sure that this does not impair the user's use of the site?
There are 4 things you can do.
And some other people have suggested:
If you are using common libraries (such as jQuery, Prototype or Dojo), you can offload the file to Google and make them serve it, this gives you several advantages:
Note: The version you ask for can have a large impact on the caching characteristics: asking for jQuery 1.4.2 will give you a file that can be cached for a year, but 1.4 can only be cached for an hour.
You can put the whole library into one js file and compress the file. However, it really only matters for the first loading of a page. After this your js file will be cached in the browser, in particular if you set the cache-expiration long enough. Hence any consecutive hit will not load your js file anymore.
In addition to the answers above, you can use the Google Closure Compiler to automatically compress and optimize your JS while integrating with other 3rd party libraries (jQuery, YUI, mootools, etc.)
If you have a number of page elements & access to separate domain, you can consider hosting all static files including the large JS file on the second domain.
As Steve Souders notes in his High Performance Web Sites blog -
elsewhere he writes..

GATESVILLE (January 24, 2013)-- Shawna Phalene Johnson, 38, and Joseph Ryan Johnson, 17, were in the Coryell County Jail Thursday, charged in connection with an ongoing investigation of an area marijuana distribution ring.
It wasn't clear Thursday whether the two are related.
Coryell County deputies and McGregor and Gatesville police officers arrested Shawna Johnson after executing a search warrant Wednesday morning at a home in the 300 block of North 19th Street in Gatesville during which more than four ounces of suspected marijuana was seized.
Joseph Johnson turned himself in a short time later at the Coryell County Sheriff's Office.
Shawna Johnson is held on a McGregor warrant charging engaging in organized criminal activity.
Her bond was set at $10,000.
Joseph Johnson is also held on a McGregor warrant charging engaging in organized criminal activity.
He's also charged with possession of marijuana over four ounces, but under five pounds.
His bonds total $20,000.
The arrests were the result of a joint investigation by the Coryell County Sheriff's Office and the McGregor Police Department.
Other arrests are expected, authorities said Thursday.

I know that in a very general sense, yeast = good, bacteria = bad. But why is this? Do bacteria produce alcohol like yeast? Is yeast a subset of all bacteria, or vice versa?
Bacteria and Yeast are not related in any genetic sense.
Yeast, by and large, eat sugar and produce alcohol and various esters and phenols (and CO2). To most brewers (and vintners), though, the only yeast of any consequence is Saccharomyces, and any other microbe is to be avoided at all costs.
Brettanomyces is another yeast genus, which typically produces "wild" flavors (from pineapple and cherry to horse blanket and mouse poop) and aromas ("Bad feet or good cheese," as a friend of mine says). It is considered a flaw in many beers, but is essential to the flavor of a certain subset. Brettanomyces can also break down and consume sugars that Sacchromyces finds unfermentable.
Different bacteria eat different substances and produce different things as a result. There are several that are useful in brewing certain beers (Flanders Red/Brown, Lambic/Gueuze, Berliner Weisse, and other beers inspired by those styles).
(See "Wild Brews" from Jeff Sparrow for more comprehensive explanations)
You may occasionally find that a beer has been infected by something that you didn't intend. It may or may not taste good, but it is a signal that you need to step up your cleaning/sanitation regimen and/or replace old equipment (especially anything plastic). I had an APA that got some sort of infection that gave it a bit of lactic twang, but it worked well with the citrusy hops, and the infection didn't show up until the batch was almost all gone. I just drank it.
I didn't know this until pulling up Wikipedia, but yeast is part of the Fungi Kingdom, whereas bacteria are part of the (go figure) Bacteria Kingdom.
I know it's not a terribly informative answer, but it indicates that even though they're both single-celled organisms they are very significantly different.
Different microorganisms vastly change the result of a fermentation. I would argue that the strain of yeast you use usually has a greater effect on the character of the beer than anything else. Bacteria that could infect your beer, especially coliforms and lactobacilli, produce acid that sour your beer (ever wonder where malt vinegar comes from?).
Bacteria and Yeast exist in different kingdoms of the classification system we use for living things. The primary difference is that bacteria are Prokaryotes, while yeast (fungi) are eukaryotes.
If you really want to knock yourself out here is the difference between the pro- and the eukaryotes.

I tried testing random integers for compliance with Benford's law, which they are apparently supposed to do. However, when I try doing this with Python,
map(lambda x:str(x)[0], [random.randint(0, 10000) for a in range(100000)]).count('1')
I get approximately equal frequencies for all leading digits. Why is this the case? Might it have something to do with how the pseudorandom number generator, the Mersenne twister, works?

Best Practices in Trading: Response to the TraderFeed Poll
Readers provided many thoughful responses to this idea, posted to the blog and directly emailed to me. The gist of the feedback was:
1) There is a considerable demand for quality education from experienced traders - Almost all the responses were complimentary regarding this blog and its emphasis on trader development. Respondents expressed what I would call a desire for training--teaching of hands-on skills--as opposed to a simple dissemination of information. Most responses were very positive on the idea of trader collaboration, though there was considerable difference of opinion over what should be shared and how.
2) There is considerable skepticism regarding the majority of trader education efforts currently available - If I had to summarize the feedback in a single sentence, I'd say that a very high proportion of traders don't perceive value in the majority of conferences, books, and mentoring services that are out there. These are perceived as overpriced and/or lacking in practical, useful how-to skills. I have heard a number of accounts of questionable services costing thousands of dollars, well beyond what is prudent for beginning traders to spend as overhead.
3) There is widespread skepticism over my idea regarding using signals from backtested trading systems as tools for decision support - The most common concern mentioned was that these signals could become a crutch, rather than an encouragement to original thinking. The signals were perceived--understandably--as not being of true educational value if they are not accompanied by the underlying system logic. Among system developers, of course, there is a great reluctance to share such system logic and potentially diminish its value. Many traders are also concerned that signals from systems could become invalid over time as markets change.
I have taken a few days to think carefully about this feedback, and I've benefited from consultation with a number of colleagues whose opinions I value. Here is my proposal to move forward with collaborative trader education:
I propose that we begin a special blog feature called Best Practices in Trading. Best Practices posts would be so identified in their title and would describe how-to skills and methods that have been helpful for traders. The novel feature in this proposal is that any TraderFeed reader is free to submit a Best Practice for inclusion on the blog. (Procedure for submission appears below). Experienced traders who would like to be contacted by a programmer for collaboration (or vice versa) could share an idea and connect for their own mutual learning (just as I recently placed the experienced trader in touch with Henry Carstens to improve his trading rules). Beginning traders could share learning strategies, setups, exits, and psychological techniques that are working for them and then receive feedback from many experienced readers who could offer further suggestions.
The Best Practices feature would accomplish several goals:
1) It would capture the knowledge and experience that each of us possess and stimulate interactions to further those;
2) Archived over time, it would provide a meaningful trading knowledge base;
3) It would provide traders, bloggers, and vendors with a sizable audience of several thousand readers for rich feedback (much as I benefited from the poll feedback);
4) It would expand the coverage of this blog to a variety of markets and trading strategies, enriching all of us.
Here's how it would work:
To submit a "best practice", you would simply email me (my address is at the end of the "About Me" section at the right hand side of the TraderFeed home page), placing "Best Practice" in the subject header. Your best practice would be briefly described in the body of the email, providing enough information to enable readers to try out the idea for themselves. I would copy the material into the blog, add my own, separate commentary and ideas, and post for everyone to see and respond to. If you want the "best practice" to appear under your authorship, you would include your name and a brief bio blurb. If you wanted readers to contact you directly (optional), you could include your contact information in the bio. I would format it in the post so that bots don't pick it up and deluge you with spam. Alternatively, if you'd rather remain anonymous or just have readers respond to your idea through the comment section of the blog, that would be fine too.
Groundrules for submission:
1) I will review all "best practice" submissions. I welcome submissions from other bloggers and from vendors of trading products and services as long as the submissions have clear educational content and are not primarily for self-promotion and advertising. I will happily include links to the blogs/sites of those who contribute entries. Submitted items should describe practices in how-to terms as much as possible, while staying within a reasonable reading length. If I need to edit a submission substantially (not just for wording), I would ask your permission in advance. I will exercise quality control over submissions and I will not permit flaming of other people's comments or ideas.
2) You are free to post your own submissions simultaneously to your own blog or site; if you do, I'll link to your URL. I do request that others not publish the best practice material on their own sites without the author's expressed permission. I will not use submitted material for any publication purpose other than the TraderFeed blog. I'm not looking to profit from others' work. Everything on TraderFeed will remain free of charge.
3) If you provide me with your contact info, I will not share it with any other groups. I do not maintain a subscriber list, and would never sell email information to advertisers or other groups.
4) Over time, I will create a separate archive of Best Practice posts so that readers will find your work in the future.
TraderFeed currently averages about 1700 unique reader visits per day. A similar number of readers access my personal site. If only 10% of readers contribute one good idea, we would have quite an online encyclopedia of trading methods--at no cost, other than the time it takes to write an email. I ask that readers challenge the premise that expertise is something possessed by others. You have gained experience, and you have learned. If you can share the expertise you've already acquired--modest though that may seem--you will help to advance others, and you will attract the comments and suggestions of others who might be of help to you.
I will get the ball rolling on Monday with an initial best practice post, so you can see what one might look like. Then, if you decide to contribute, you can email me with your basic idea before writing it up and I can make suggestions for your entry. In most cases, I will provide personal feedback to traders who submit "best practices" as well as commentary on the post.
Of course, I welcome comments and suggestions regarding this blog feature and am happy to make modifications to meet readers' interests and needs. My goal is to make trader education a social process, rather than a one-way stream of information from a self-anointed guru to a relatively passive group of receipients. My hope is that, among ourselves, we can generate more solid ideas and superior learning and training than could be accomplished through any number of expensive and ephemeral seminar/workshop/coaching events.
Thank you so much for your interest. I look forward to this collaboration.

Hi Brett
Although I do not qualify to participate in your new Blog, being a novice online trader of a year, I think it will serve to enhance our trading at whatever level.
I look forward to reading this new Blog as I believe my mentor will participate whenever.
Good start to the Year of the Pig- Feb 18, 2007!
Bulls and Bears make money, only Pigs get slaughtered.......... your new Blog is timely to come to the rescue!
- Brett Steenbarger, Ph.D. said...
Hi Yin,
I really appreciate your interest and hope we all can avoid slaughter in this Year of the Pig! While I understand that you're a novice, I suspect you have some insights regarding lessons you've learned (sometimes the hard way!) that you could pass along to other novices. I'd welcome your participation if inspiration strikes!

"My goal is to make trader education a social process"
I'm really looking forward to this new blog. I don't have the ability to backtest and give statistically based trades right now, but I look forward to being able to share some of my own ideas and being able to look at other traders' ideas as well.
- Brett Steenbarger, Ph.D. said...
Hi LifePost,
If I get enough submissions, I'll probably turn the "Best Practices" into a separate blog altogether. For now, it will be a feature on the TraderFeed site. I'd enjoy getting a submission from you regarding one of your ideas. If you'd like to try to connect with other traders, do indicate in your post. Thanks for the interest!

An excellent series idea. I look forward to reading and contributing! If I'm correct about the series' premise, many of the ideas behind the strategies from our 'Strategy Sessions' series would be appropriate material.
- Lauriston said...
Quite seriously, this could turn out to be the best contribution to the field of trading, probably ever! Will beat the Internet and many changes in securities laws that have given small traders access to the "Old Boys' Club". Why? Because all the other efforts only give access to small traders to lose their shirt, whereas your efforts will help traders in their pursuit of making money!!! Thanks for all your fantastic effort.
- Brett Steenbarger, Ph.D. said...
Hi David,
Yes, you're absolutely correct. Ideas behind the strategies would be fantastic "best practice" entries, and I'd love to have your participation. Thanks!
- Brett Steenbarger, Ph.D. said...
Hi Lauriston,
I really appreciate your interest and support. I have been pleased with the response to the best practices idea so far and hope that we can sustain a flow of high quality ideas. Thanks!

Cruise, Wildlife Viewing, Hiking, Swimming, and Snorkeling
Explore the islands that inspired Darwin. Experience wildlife that doesn't fear people and is so diverse and abundant you'll have to watch your step to avoid disturbing a napping sea lion or resting iguana!
This morning we're off on the 90-minute flight to the Galapagos! While your exact itinerary depends on your cruise and Galapagos National Park regulations, the following islands and activities are all possibilities:Baltra: Former World War II U.S. military base and now the location of Galapagos's main international airport, it's where you'll probably arrive and depart the islands.Santa Cruz: Visit the Charles Darwin Research Center, learn about their preservation work and admire the giant tortoises in their breeding program. We explore the island's lush volcanic highlands where wild giant tortoises graze and the island's mangrove-flanked channels and shore looking for land iguanas, green sea turtles, sea lions and schools of spotted eagle rays and golden rays. Bartolome: An otherworldly volcanic landscape where lava, mangroves and golden sands converge. Fun hikes and fantastic views plus a chance to snorkel with penguins--a tropical oxymoron! Santiago: Home to Galapagos fur seals and some of the best "tide pooling" in the islands. Good opportunities to see herons and marine iguanas grazing among red sally light-foot crabs. Swim and snorkel with octopus, sea horses and star fish. Isabela: Largest island in the archipelago, its dramatic landscape was formed by six volcanoes. We visit saltwater lagoons, home to flamingos, and investigate Isabela's caves and shoreline on the watch for penguins, dolphins, whales, sea turtles and the elusive ocean sunfish. Fernandina: The youngest island, Punta Espinoza is a marine iguana heaven where we see them with sally-light foot crabs, flightless cormorants, Galapagos penguins and sea lions, all with Isabela's stunning volcanoes as a backdrop. Floreana: Great snorkeling with friendly sea lions. We see flamingos, pintail ducks, swallow-tailed gulls and marine iguanas. "Post Office" Bay is where an empty barrel was set up by an English sea captain in 1793 as an informal postal exchange. Visitors continue the tradition and put unstamped mail in the barrel in hope its reaches its destinations for free. Espanola: Snorkel and stroll the island's lava fields and lovely beaches--sea lions, marine iguanas, manta rays, white-tipped reef sharks. Great birding with hooded mockingbirds, Galapagos hawks, Darwin finches, red-billed tropic birds, blue-footed and Nazca boobies and the world largest colony of waved albatross.San Cristobal: Location of Puerto Baquerizo Moreno, the capital of Galapagos Province. We visit its Interpretation Center and little Lobos Island, a favorite spot to snorkel with sea lions. We disembark and fly back to Quito on the final day.
These cruises are available in 4, 5, 6 and 8-day itineraries. See the drop down box below Trip Details for dates and pricing. The Detailed Itineraries link will provide the list of islands visited by each ship's itinerary.

Answers sought in Bellaire vandalism
May 14, 2013
WHO did it and why? These are the questions that Bellaire police seek to find the answers as they investigate the vandalism to the Belmont County Eastern and Northern courts on Monday....
LifeLongOV didn't learn much respect, and he earns none from life-long Ohio Valley residents who read his tirades. I'm wondering if his parents are proud of him. He must be exceptional since he must never had made a mistake.

CNN cited the American Immigration Council's recent report ...
Employment Verification: Repairing our Broken Immigration System
We can expect comprehensive reform legislation to mandate that all employers use some sort of system that verifies the work authorization of all workers. Since this will affect every single worker in the United States - immigrants and citizens alike - and because an error in the system can cost a worker his job and paycheck, it is important to make the system workable. This report lays out the must-haves for any broad employment verification system and lays out why a system like this can only work if it is within the context of a broader reform package.
Turning off the job magnet for unauthorized workers is a key part of comprehensive immigration reform, and the creation of a system to verify the work authorization of all workers is likely to be an element of any comprehensive immigration reform bill. The current I-9 system, which was created as part of the Immigration Reform and Control Act (IRCA) of 1986, requires all workers to provide their employer with documents that prove identity and work authorization. Already, that system is becoming less paper-based as it evolves into an electronic employment-verification system (EEVS). The U.S. government's current EEVS program, known as "E-Verify," is mostly voluntary and relatively small.
Over the past several years, immigrant advocates, privacy experts, and government agencies have identified potential problems associated with E-Verify that impact foreign-born workers as well as U.S. citizens. Since EEVS affects every single person working in the United States—immigrants and citizens alike—and because an error in the system can cost a worker his job and his paycheck, it is important to make the system workable and effective. Employment verification, when accompanied by comprehensive immigration reform, can be a useful immigration-enforcement tool. Taking care to get employment verification right is essential. Before expanding the EEVS program, policymakers must acknowledge the shortfalls of the current system and ensure a better-designed program that will protect both foreign-born and native-born workers.
Any new or expanded electronic employment-verification system (EEVS) must address the following broad issues:
- The data in government databases must be accurate and regularly updated. The current DHS and SSA databases upon which the E-Verify system is based are error-ridden. Database errors can mean that U.S. workers will lose their jobs and their paychecks. Data accuracy is the key to a well-functioning verification system.
- There must be adequate protections for all workers. There will always be some level of error in the system because of mistakes that people make when entering data, or because of deliberate misuse of the system. However, we need to ensure that there is a process in place for anyone who is mistakenly told he is not work authorized.
- The government must have adequate resources to run the system. Making electronic employment verification mandatory will mean tens of millions of workers and employers will use the system every year. The government agencies responsible for implementing the system must have enough funding and personnel to handle the huge increase in use.
The following are principles for employment verification:
- Comprehensive immigration reform: While there will be pressure on Congress to expand E-Verify outside of comprehensive immigration reform, a mandatory EEVS must not be implemented unless it is part of comprehensive immigration reform that also includes a legalization program for current unauthorized immigrants, creates flexible channels through which future immigrants may enter the United States legally, and reduces the incentives to hire unauthorized workers. Employment verification alone does not address the structural problems with our current immigration system, as outlined in IPC's Breaking Down the Problems, What's Wrong with Our Immigration System?
- Apply to new hires only: Currently, approximately 160,000 employers are registered with E-Verify—a tiny percentage of the 7.4 million employers in the United States. Approximately 8.5 million queries were run through E-Verify in Fiscal Year 2009. A mandatory system would mean that roughly 60 million new hires per year would have to be run through the system—a huge increase. Re-verification of the entire workforce would place an even greater burden on workers, businesses, and the government agencies responsible for implementing the system.
- Data accuracy: Every effort must be made to ensure that the data accessed by employers is accurate, continuously updated, and subject to review. The SSA database alone has a 4.1% error rate—amounting to 17.8 million discrepancies, of which 12.7 million pertain to native-born U.S. citizens. The DHS databases also have high error rates. No U.S. citizens or legal immigrant workers should be denied employment because of errors in the database.
- Documentation: The documents that workers are required to present must be documents that all U.S. citizens and legal workers will reasonably be able to obtain. Currently, more than 13 million American adults cannot easily produce documentation proving their citizenship. Some past proposals would have required workers to produce a REAL ID-compliant driver's license. However, no state has fully implemented the REAL ID Act, and many states have refused to implement the law. As a result, no Americans currently have REAL IDs.
- Worker protections: There must be rigorous oversight of the program and significant penalties for employer misuse of the program. Through experience with the I-9 system and E-Verify, we know that some employers discriminate against workers who sound or appear "foreign." Other employers pre-screen workers, and some retaliate and take adverse employment actions (such as restricting assignments or training) before the system provides a final response. Some employers also fail to inform workers of their rights under EEVS.
- Complaint and redress procedures: If a worker is adversely affected by an employer's misuse of the program, or because of a database error, a clear complaint process must be available so the worker can report the incident and receive redress.
- Due-process protections: Individuals must be allowed to view their own records and contact the appropriate agency to correct any errors that exist. Administrative and judicial review must be available so that workers are able to seek compensation from the government if an error in a government database results in denial or termination of employment.
- Privacy protections: The amount of data to be collected and stored must be minimized, and penalties must be created for collecting or maintaining data not authorized in the statute. Furthermore, there must be serious penalties for use of EEVS data to commit identity fraud, unlawfully obtain employment, or for any other unauthorized purpose.
- Resources: Sufficient resources will be necessary to implement and maintain a new or expanded EEVS, including additional personnel to handle the enormous increase in queries associated with a mandatory system. Without resources to upgrade and maintain the databases, and to hire and train personnel, a well-functioning, mandatory, employment-verification system will be impossible. The cost of the program cannot fall disproportionately on immigrants, employers, or U.S. citizens.
- Outreach: Significant community outreach and education must precede any expansion of EEVS in order to inform both employers and workers about how the system works, their rights and responsibilities under the new system, and avenues for redress in cases of error or unfair employment practices.

Medications Causing Sun Sensitivity
Last Modified: August 13, 2012
Are there special precautions to take if you are on a medication that says "may increase sun sensitivity?"
Christopher Miller, MD, Dermatologist & Moh's Surgeon at Penn Medicine responds:
Certain medications, such as tetracycline antibiotics, can increase your sensitivity to the sun. The precautions when you take these medicines are identical to the common sun-safe habits that we recommend: avoidance of the sun is best, clothing to cover up as much of your skin as possible, and sunscreen to exposed areas.

First impressions
Got a chance to look at this today, and, erm, well, if compatibility is the goal then it's wide of the mark I think.
Our application is ready to ship, so the number of issues under 4.0.7 is very low, and certainly nothing too serious.
Thought I'd try with the new beta since you've stated that it should be compatible, and am interested in seeing the performance improvements, especially under older IEs...
Under 4.1.0 am having lots of trouble with my custom tree (additional data being attached to the root node is getting lost, breaking my configuration and load process completely), and grids appear to not be displaying all data (can see two records coming back, but only one is in the grid, so I assume store).
No real progress with either of these yet, but will try and find out what is going on... looking at the tree first.
Some observations so far; will add more as I spot them.
- AbstractComponent.getState used to return an empty object if there was no state, now it returns null.
This means classes overriding the behaviour need to OR the result from calling parent with {} to ensure they can use the object.
- Can't slice my theme; get a whole load of errors.
Assuming it needs a new version of the SDK? If so where is it please (Windows please, my MBP is no longer my work machine)?
- Changes to TreeStore.setRootNode appear to be causing my first problem with my tree... still investigating. Suspect it's my old mate NodeInterface, it really is the bane of my life that horrid thing!
Subjectively, layout seems snappy, but of course since it's having trouble loading most of my data it's bound to be quick
More as I get it.

There are lots of fixes in there for trees and grids. I personally haven't seen any problems with my grids and I usually try to stay away from trees (have never liked them so just my personal opinion ). So things should work but when there are this number of major reworks then it is kind of to be expected to have some hiccups. Best of luck to you and we would like to hear of any progress you make. Any tips would be looked at as we develop for a GA release.Mitchell Simoens @LikelyMitch

Progress of a sort; needed to add my additional "fields" (which they are not really) to an explicit model behind the TreeStore rather than rely on the implicit one that gets created automagically...
NodeInterface is still biting me later in the process, but have a call to the server going now at least, just b0rks when it comes back
4 Jan 2012 4:00 AM #6
Finally got my tree loading through a combination of updating my model (ensuring that defaultValue for fields is set to undefined rather than the empty string for objects that I add into the data), and hacking one line of the new code out of NodeInterface.
In appendChild, the loaded flag is being set when it shouldn't be (at least if I comment this out then everything works fine):
if(!node.isLeaf() && node.phantom) { node.set('loaded', true); }
Edit: Ahhh, it's the idProperty stuff in the model I think... will try it.
Edit2: Yep, setting my idProperty gets my tree loading. Glad I read the "gotchas" post
4 Jan 2012 5:43 AM #7
Calling load on an arbitrary node (i.e. refreshing children) appears to be broken; possibly something to do with clearOnLoad... looking into it.
Edit: Sorted.
When introducing an id property for your model, it's essential it is unique otherwise get some strange effects (I used a type/id combo, since auto number db ids can clash across tables).
I think to do with the clearing of removed nodes that has been introduced.
3 Jan 2012 9:21 AM #8
Yeah, NodeInterface... grr
The constructor returned by getPrototypeBody calls the parent Model class, which only allows data defined in the model's fields to persist. Suppose I could override decorate, since that "hacks in" the fields it needs...
This class really is so out of place with everything else in the framework though, it's just so inaccessible.
The only way to fix issues with it's methods is to, I suppose, override getPrototypeBody, call overridden, then apply your overridden methods to the object returned...
3 Jan 2012 9:24 AM #9
Ahh, just saw your reply Mitchell, long time no "speak"... really must refresh more often
So, is there a plan with some timescales, i.e. when do I need to get my rants in by so can have a hope of them getting picked up, or at least answered?

I'm looking for a function where f(x1, x2) = f(x2, x1), but f(x1, x2) CANNOT equal any other f(xi, xj). Also, f() must also be reversible, so I could calculate xi from f(xi, xj) and xj. Can anyone think of such a function?
As an example, f() cannot be bitwise addition: bin3 + bin5 = bin8, but bin1 + bin7 = bin8 also.
edit: Thanks all. I'm just going with f(x1,x2) = implode(delimiter, sort(x1,x2)). I figured maybe there was a more elegant solution. The insights on bounding were good though. I would give upvotes all around but I don't have enough rep yet.
