Just to clarify, I wasn't trying to compare Google and RIM. After I wrote my comment, I realized some people might draw that conclusion. I was just pointing out, based on my own experience, that trading stocks based on technical indicators is not always the best idea, as was implied by the post I was responding to.
I think that one of the reasons there is so much hate directed to smokers is that disliking those that are different from you is an unfortunate part of human nature. Smokers are virtually the only group left that it is politically correct to put down and so people flock to them as a kind of punching bag.
Another reason is jealousy I think. People who used to smoke, or are two inhibited to allow themselves a publicly visible vice feel jealous when they see somebody enjoying a smoke and take it out on them.
I have no idea how this could be viewed as insightful. First there is the obvious point that alcohol a depressant that modifies behavior and makes you generally stupid and tired, wheras nicotine is a mild stimulant which may slightly increase mental function more like coffee. More importantly though, in what kind of workplace do you not get to take a break every couple of hours? I work at a desk a lot of the time, don't smoke, but I certainly take breaks where I go for a 5-10 minute walk outside, just to stretch and get away from my computer. Any workplace where employees can't do this is asking for higher healthcare costs.
When people go out for a cigarette, they are taking a short break from work. I grant you they are using an addictive drug during their break, but so is anyone who goes for a coffee or chocolate bar.
I just heard about this on the radio driving home. I am in Canada. Our equivalent of the FTC fined two companies, one 500K, one 18K. They also asked that the companies respect our do not cole registry from now on. My understanding is that in Canada at least, they can still call, just not if you chose to give your number to the DNC registry. Seems a bit light of a punishment.
Unfortunately, in many universities (I teach in Ontario, Canada) government funding is tied to metrics like student retention. My university lets in all kinds of people that shouldn't be there, then blames the faculty members when they drop out or fail courses. We have caps on the percentagle of D's, F's and withdrawals we are 'allowed' to have in a class. In cases where the DFW rate is too high, the adminstration has converted failures to passes and blamed the teacher. The result is grade inflation and passing people who shouldn't pass. Right now this is not a problem with online universities, but once you have many businesses competing for pupils, things like dropout rate will become important to them and the numbers will be fudged.
Sample size is not a problem for any moderately sized university. I teach at a relatively small university but often have 100+ students in my classes and sometimes I am teaching only one of several sections of that course. Year to year and between different sections, there is tons of room to do statistically relevant research.
I worked at a research MRI lab for a number of years and have visited many others. I have never seen helium be recycled, it boils off and the magnets are refilled. I know the technology exists to recycle He and have seen it advertised, but it is not in common use, at lease in the research circles I travelled in.
Look up the amount of energy stored in a charged MRI magnet. The usual figure you hear is a the same kinetic energy as a 747 coming in to land. I think this is high, but there are 100's of amps of current flowing through an inductor made of many kilometers of wire. It's a lot of energy.
Now look up the term 'quench' in relation to supercon magnets. If a small part of the wire inside the coil stops superconducting, it suddenly is subject to resistive heating and sets off a chain reaction which rapidly brings the whole coil out of supercon mode, releases all the energy stored, and boils off the cryogens.
This is not a rare event and not something you would not want to happen with a magnet filled with an explosive element.
Also, just because something superconducts, it does not mean it can be economically drawn into a long thin wire for use in a MRI magnet. I think commonly use a Niobium superconductor for MRIs and I bet there is a reason.
I'm unusual enough that whatever I'm doing is probably an outlier in terms of marketin usefullness, whether it's power consumption, spending habits, location, etc. It pisses me off that data is being collected about me whatever I do, but I would rather focus my energy fighting other battles.I agree with you that its best to just assume everything that can be monitored/logged is and act accordingly.
If enough people are bothered by this, I wonder if it is ecomomic for someone to make a load balancing system that draws a constant current from the mains (at zero power factor), and stores energy in a battery system which powers the house. There could be different privacy options; for example random power draw or a consertvatively high constant power which would have to be blown off if the batteries get full charged. Or, in municipalities like mine that have time of use pricing, all the energy could be stored at night.
This would certainly be expensive and wasteful but might be a product for private people
What are you doing that you can't do with a CSV or tab delimited text file? I can't speak for mathCAD or solidworks but I routinely import tabular data into matlab using dmlread
Is there some advanced feature of excel that you are using with matlab, or are you just using xlsread to read in a table? For the other software you mention, are you reading in something other than columns of numbers that could be saved in a text file?
Part of the problem with fructose is that because it has a low glycemic index, your body is not signaled to stop consuming it as quickly. It is metabolised in the liver and excess amounts are converted to triglicerides in the blood which are a factor in heart disease. There are other problems too. Please see this, admittedly not the most scientific reference but I think it makes a good case.
Normal amounts of fructose are not a problem, and it is one of the main sugars in many fruits. The problem is downing movie theatre size pops with 200+ grams of the stuff. What I would be most interested to see is people would consume the same volume of glucose or sucrose flavored drinks, or would they naturally limit the amount they drank?
This is pretty much the first sensible comment I have read going through this story. Furthermore, whenever I have bought stock, I do it with a limit order which will only execute at a price I specify. I decide what I will pay for a stock, place my bid, and if someone is offering it, then I buy it. Isn't this how stock is bought? If you read the article, the guy complains how he goes to place an order for a client (presumably at a commission rate that swamps whatever pennies a HF trader could skew the price by) and the prices keep jumping around so he finds it hard to get a good price. This makes no sense. Watch the price for a couple of minutes, pick the low end, place a limit order. This guy is just incompetent or creating a pretend problem to justify his bias.
I think there are definite concerns about HFT, especially related to the 'flash crash' stuff, and I think most of it probably adds little value, but I don't really worry about being stolen from. Pick the price you want to pay for a stock, and if it doesn't hit that price, don't buy it
One more thing related to the flash crash, what I care about more then HFT algorithms crashing the stock market for a few seconds is the non-HFT algorithms used by companies I might invest with that will cause them to lock in the losses due to that kind of crash. For example, during the 2010 crash, people who didn't sell anything over that afternoon lost nothing. But investment funds with automated selling once stocks dropped below a certain price could not buy them back later and lost money.
You could be scarring him for life you know. If he doesn't have an aptitude for math, this will not help him. If he does have an aptitude for math, this is a complete waste of time. Whatever the case, you are not helping him in any way, making him resent you, and causing who knows what kind of social problems / insecurities for him. Hopefully he will be strong enough to just laugh it off as something his crazy father made him do.
Also, maybe you should suggest he go play outside an hour in the morning and evening, if his "fun stuff" is watching TV and sitting at the computer. This will do much more for his future quality of life than math tutoring
Not to mention summer jobs. This is only important from maybe 12-14 onward (I did stuff like mow lawns and do gardening for elderly neighbors when I was 12) but a summer job is a really important part of growing up and is at least as important in a teen's development as what they are doing in school.
Sorry, I modded you overrated instead of funny by accident. Funny how I get a big warning about how if I comment my moderation will be undone, but I get no warning when I accidentally let go of the mouse button over the moderation dropdown box.
This guy paid for something and didn't get it. There is a pretty obvious and quantifiable loss that happened and he should be able to get his money back. This is pretty much the definition of the right kind of thing to sue over. Its not emotional damage or coffee on the crotch or hurting yourself when your robbing someones house or whatever nonsense people get on with. Its a real tort.
Its still not really very authentic to refer to something as "epic" these days though is it? By that I mean would an ordinary person very often call something "epic" on their own in conversation? I thought this came from the "epic fail" craze a few years ago involving pictures of soccer players getting kicked in the crotch or whatever. Now the only things I hear described as "epic" are car dealerships and other advertisers that are behind the times trying to appeal to youth.
Rather than mod the post over-rated, I just want to point out how wrong it is that the parent has been modded up. Do people really it is appropriate to whine to 'the mods' (editors) to remove something you don't like from a website you are vouluntarily visiting. If you don't like the links that sometimes appear when you browse at -1 and fear for your job because of them, don't use slashdot, at least when you were at work. Take some time to learn how to use the website, and browse at +2 or +3 or something and you will never see links like that.
Whining to a higher authority to fix a minor/non-problem is not adult behavior.

Panic selling always overshoots down past where the price will eventually settle.
I remember buying some RIM stock a few years ago (for > $100 / share) based on this philosophy. Ask me how that worked out.

Could you tell me that without increasing the entropy of the universe?
If entropy is equivalent to information, doesn't the information that the particles are entangled itself represent additional entropy?
You would see slower times in the running events. Ask any runner, there is no better way to push yourself than to have someone to beat.
