I downvoted this before I read your comment below, which indicates you know much more about this topic than is evident from this comment.

As someone who has been battling something that seems to fit the description of CFS for several years, I agree with you that it is largely a psychosomatic condition, and the success I'm now seeing in overcoming it has coincided with a lot of work I've been doing to overcome emotional traumas and self-sabotaging beliefs.

That said, I have seen studies that show a correlation between CFS symptoms and active infections of several viruses including Epstein-Barre, Cytomegalovirus, and Human Herpesvirus 6.

These viruses are present in most people but dormant - whereas they are commonly found to be active in those diagnosed with CFS (along with MS, Aspergers's, Alzheimer's and other auto-immune conditions).

I was tested for EBV and CMV (HHV6 wasn't available at the lab I went to) at the time I started to feel significantly better, and was found to have evidence of previous active infections of both, but neither were active at the time of the test.

From all the research I've done, the mechanism seems to be: prolonged emotional stress/trauma -> weakened immunity and/or auto-immunity -> fatigue and illness as infections take hold and body tissue is damaged by auto-immunity.

So I guess you're right in the sense that there is no single bio-marker for CFS, but there are correlates that can help to support a diagnosis.

As for treatments, well I haven't seen any practitioners offer anything convincing. So maybe your comment was totally valid after all.
As I said in another post, the video pretty much reduces people to a secondary role. It's not so much technology enabling us or aiding us, but more we supplement technology --but only because technology is allowing us to interact.

The good is that people would have a lot of free time (presumably to do good things), the unanswered question, is now that most people are redundant, what do they do to earn a living? Magic? Bureaucracy?
I read this and thought "I'd be amazed any parent would let their child see any movie by themselves".

Then I realized I did it all the time with friends when I was 10-16 and we had a cinema 3 miles into town we would walk to, and I am only 24 this year. Its like the American Family went over-protectionist deep end in just this decade or something, because my brother who lives with his mother can't even walk to the school bus stop down the street by himself without it potentially resulting in a police call.

The SQL can look a bit complex at first, and advanced queries can look complex, but MongoDB is quite limited what operations you can do with it, so the SQL queries that correspond to MongoDB operations are fairly simple.

Here's a documentation from MongoDB which could be used the other way as well:
http://docs.mongodb.org/manual/reference/sql-comparison/

For normal use you really need 4 operations:

SELECT - query data

INSERT - inserting data

UPDATE - modifying existing data

DELETE - remove data

Everything else is either used for database maintenance or DDL (Data Definition Language, defining how the data is stored) commands.

The DDL is the main reason why some organization are considering using MongoDB, they believe that by removing the schema (definition how data is stored) they will get more flexibility, the problem with it is that if you use MongoDB you still will have schema, the issue is that the schema will be enforced by your application. And if you don't enforce the structure you'll end up with quite a mess, and very complex code.

Also if you use Java (or JVM based language) there are many frameworks that supposed to help interacting with database each has their strengths and weaknesses. There's one called JOOQ[1] that allows you to write SQL queries in Java in a way very similar to MongoDB.

Edit: There's also article about MongoDB aggregate functions and equivalent PostgreSQL: http://tapoueh.org/blog/2014/02/17-aggregating-nba-data-Post...

> As other commenters wrote, you want drivers to always follow the speed limits.

Then you need to set sane limits. A speed limit that 80+% of the people violate isn't a sane limit.

Or, you need to reengineer the road so that you basically can't speed. However, you have to accept that you are going to lose a lot of traffic and, with that, a lot of business.

Creating a 6 lane wide street and then slapping a 20 mph limit on it doesn't make sense.

A number of years ago a friend and myself worked out what could best be described as a medium frequency trading strategy based on historical trading data. This was when high frequency trading was still in its infancy. The algorithm would find certain stocks with a high frequency of highs and lows. In simulation, it worked perfectly. We were making loads of "virtual money." This got us excited enough to unleash the algorithm on the world. Guess what the problem was? All the testing in the world can't account for the market dynamics your algorithm itself creates. That was our biggest downfall. Time and time again it worked in simulation but in the real world, its trading actions based on historical data was in fact impacting the market in unexpected ways that we were ultimately unable to account for.

What's the percentage of drivers violating the speed limit? Maybe that limit IS too low.

A speed limit is supposed to be set such that 85-90% of the drivers obey it naturally.

Confusion is the first step to learning anything worthwhile. We shouldn't be shielding people from it. I have a feeling that if as a species we're going to create some Media for Thinking the Unthinkable, it won't be by continuing to emulate 2D paper. Of course people are going to "require user training" - if we stopped to design for the most common denominator we'd never increase the scope of our expression.

We navigate and create complex systems every day that could be more easily absorbed and understood with more complex, dynamic representations. I see the world as pictured as one where Word no longer exists, where you can send someone a simulation and be understood in a few minutes instead of spending hours with a whiteboard or months getting a proof of concept built by a development team.

Clever (YC S12) - Full Stack Engineer - San Francisco - $100k-$150k+, plus above-average equity

At Clever, we’re building a distributed platform for educational software. There are a lot of great learning applications that schools want to use, but they have some constraints that make using software difficult: for example, picture a teacher getting 30 first-graders to log in at once. Our API and single sign-on solutions help schools solve those problems. Schools are on board, and we’re now in 25% of schools in America.

Right now we’re a team of 50 (22 engineers) based in downtown SF. We’re looking for full-stack engineers who like:

-Go, Coffeescript and Python (or are willing to learn)

-hard technical problems (managing a huge, constantly updating data pipeline)

-tech talks on everything ranging from the history of hip-hop to neuroscience to exoplanets

Check us out at https://clever.com/about/jobs#engineer-full-stack, or check out what we’re working on at https://github.com/clever.
By some definitions I'm "elderly", but I can read small print, operate tiny buttons on devices, and think abstractly just fine. I do my best, keeping up with technologies is hard, but doubt I'm alone in that respect.

In any case, I'm excited about the Firefox OS not because I'm old but because I'm interested in a technology that holds a lot of open-source promise: lower costs, non-coercive apps, respect for user privacy, among others. The app (and OS) development model encourages transparency (promotes security) and with a "lower bar to admission" invites wider participation among users.

Since I'm pretty familiar with web programming I think it will be great when FOS devices become available in N. America. I think it will attract many people looking for the alternative it offers.

Us elderly folks tend to value simplicity and utility over bells and whistles, after all, by default a senior's life is complicated enough. We're old, we don't have time to waste, we see through a lot of the marketing hype and unnecessary crap. When there's a task to do gimmicks are just a hassle--making a phone call should be simple, sometimes it's all a person is aiming to do.
Some kids react poorly to things. I love movies and want the kids to enjoy the experience.

Personally, I'm pretty unflappable, although things like horror movies don't do anything for me at all. My wife cannot tolerate gross stuff at all. Criminal Minds (prime time TV fare) kills her appetite.

My son is too little to develop preferences, but my one nephew hates movies where someone pops from an off camera to attack somebody. Freaks him out, even in a not scary movie.

I've had CFS for several years, have tried all kinds of medical and natural remedies, and am finally having good success in overcoming it.

From this experience, here are my thoughts:

- I do believe its primary cause is psychological, but it's symptoms are real, physical and profound.

- I do believe it should be taken very seriously by mainstream medicine.

- I believe it can be cured, but not by focusing exclusively on physical symptoms, or through any treatments currently offered by conventional mental health professionals.

The best progress I've made in overcoming the condition is through a non-medical treatment to identify and correct subconscious traumas and self-sabotaging beliefs. The closest thing in mainstream medicine is CBT, but what I'm doing seems far more effective.

> His comment was how the original alien was smarter than than the crew, but in the second movie the aliens are just dumb animals.

In the first movie, there was only one Alien and it acted more like a lone hunter. In the second movie, there were lots of aliens and they acted like a hive. I think that it's possible for both of these to be consistent with each other.
You did not specifically list the things you were talking about - you ended the list with "and many other factors". That's not explicit at all. Then you said Call it 'probabilistic causes of non-equal representation', at which point I thought you were finally being clear. My mistake.

If it turns out that 4x the effect is due to cultural privilege, of the kinds I listed, and 4x is due to demographic, bias, so what?

Scroll up - as I said, you completely lost the context of the conversation.

Hackuser was asking "if a system is truly meritocratic then why would 38% of a population[1] produce 90%[2] of the winners?" The implicit assumption here is that "money, power, privilege" (as defined by hackuser) and merit are distinct, otherwise the question makes little sense.

Now if only 4x the effect is due to cultural privilege, then the answer to his question is "yes" - a perfectly meritocratic system can have disproportionate representation of Asian males.

Thanks for the feedback! Yeah, truth be told, there are a ridiculous number of skills/experiences that aren't required but would be really awesome. We erred on the side of having relatively few "requirements" and all of the nice-to-haves we could think of for what we're building. You could have any combination of those (or none) and still potentially be someone we'd love to hear from!

Your product looks sharp. Congrats on the growth and good luck with the hire.
Couldn't agree with you more. Higher salaries very much represent a company's ability and desire to pay top dollar. I do caution on the long term bet. It's not as solid as may seem. I've come across many companies who throw money at the problem of not being able to attract/retain talent with market rate range salaries. Could be a number of reasons, including politics, lack of interesting projects, unsustainable culture, etc.

Another major point to keep in mind is salary today vs growth in coming years. Getting a high salary today may bring with it unrealistic expectations. It may be your future bonus and raises that suffer. Your annual review will roll around and the managerial perception will be that you're already paid more than everyone on the team, so you're not getting a notable slice of the budget.

My point is that things aren't always black and while, and long term may be not as advantageous as they seem. If you're looking for a career, hoping jobs every year will not help. Becomes a red flag on the resume.

> making me more valuable in the long run so eventually I can make more money

Sorry to burst your bubble, but the "more money" from experience gained while taking a paycut will pale in comparison to "more money" from the number of years you state on your cv and dollar value of your last salary.

In perhaps clearer words, taking a paycut for career growth will most likely just prohibit your potential future salaries regardless of how much technical experience you gained.

This of course all changes considerably when you're talking founding/early employee where minimum wage is a real possibility..

return (a && b);
}

or does something in the standard prevent this?

I'm not sure I'd call them cliches, but the kind of one dimensional portrayal of the various marine characters. For example the Bill Paxton character--he starts the film the most outwardly bloviating and macho, and becomes the most (annoying) scared. It was played to 11 which made it feel very shallow to me. The company man was also a pretty one dimensional character. I also felt the mothering at the beginning and with Newt kind of cliched. I was very glad both Hicks and Newt were killed off for Alien 3, which in its directors cut version, I liked much better than 2.

I guess not liking Aliens much puts me well in the minority.

There's a difference between an army and a police force. Police are there to enforce the law and neutralize criminals.

Generally speaking, the police don't want to kill anyone. They want to capture the suspect and move on. Back in the day, non-lethal force meant beating the guy with a big stick, but liability became an issue. So now we pull guns on dumb kids, and a jumpy cop results in a dead dum kid instead of a broken arm.

Armies are different. Since the US Civil War, total annihilation of the enemy's ability to make war has been the rule of the day. You err on the side of killing, becuase a stunned enemy lives to fight another day.
