  1. correlation != causation on Does Scientific Literacy Make People More Ethical? · · Score: 3, Interesting

    It is very much possible the more ethical types gravitate towards science rather than scientific literacy made them more ethical. Most likely a whole combination of behaviors and attitudes occur together, being ethical, liking science, etc are all possibly triggered by a deeper primary cause. All these attitudes could be just the external symptoms.

  2. Re:50mph? in your dreams. on Iranian Lab's Quadcopters To Rescue Swimmers · · Score: 1

    Even the variable pitch rotors used in full sized helicopters are not all that efficient compared to fixed wing aircraft. (Here "efficiency" is defined by the energy used to move payload). You see the fixed wing aircraft produce enough thrust to overcome drag and the aerodynamics of pushing the wing into air creates lift. Anything that hovers must produce enough thrust to overcome the weight. Typically in a fixed wing aircraft the Lift (or weight) to drag ratio is above 10. Thus you are using much smaller engine for the same weight in fixed wing aircraft. So purely by fuel efficiency point of view, rotary wing aircraft can never compete with fixed wing aircraft.

    So all these fired valets go back to school and earn a degree in electronics and communications? We need to leave a few jobs for the people with low skills and low motivation. It would cost the society more, when these hungry despo people fall into crime or become homeless.

  4. Oh! Great! the last few jobs for part timers gone! on A German Parking Garage Parks Your Car For You · · Score: 0
    Working as the parking valet is one of the last few part time jobs still left in the great land of USA. Now even that is in peril. The gas stations are fully automatic now. So are most parking garages. There are very very few jobs available for low skilled people. We keep telling poor people, "You are poor because you are not willing to pull yourself up with your bootstraps and find a job", and at the same time we keep cutting social programs, and invest more and more on taking even the last few jobs away.

    It is one thing to have an autonomous car that improves safety, and relieves the driver of strain. It is entirely another to make this level of investment for the paltry return of firing a few parking valets.

  5. Re:Define "presence" on US Senate Passes National Internet Sales Tax Mandate · · Score: 1

    You don't get to decide what is legitimate and what is not. You may believe it is not justified and vote accordingly. But once a lawfully elected levies a tax, you got to pay it. You can sue, and if you prevail you can sue to get it back. But you are not the deciding authority about what is legitimate and what is not. You don't get to decide which laws you will obey and which ones you will ignore based on your personal opinion.

    If you go to Oregon and bought it yourself, you still owe taxes to California. You need to declare you bought an item for use in CA and remit the tax yourself. If you bought it in CA, the vendor collects the tax at the time of sale that is all the difference is. You owe the tax. Just because CA finds it impractical to come after you does not make it go away. You are still a tax cheat. All that grandiose talk about government and taxes does not hide the fact that underneath it all, you are just a simple selfish guy/gal.

  8. Calling it news does not make it news. on Pew Research Finds Opinion Dominates MSNBC More Than Fox News · · Score: 0
    The right thing to say is, MSNBC calls 90% its programming opinion and classifies 10% as news. Fox calls 45% of its programming news and 55% opinion. But in reality, what Fox news calls news, is essentially reporting as news what is said in its opinion section. Some talking head comes on its opinion section and says something. Then the news arm comes on and reports that "A said this (in our opinion side)".

    To me it is more insidious to mislabel opinion as news. It is a greater sin. On that count alone, admitting 90% of what is dished out in MSNBC is opinion is very honest,

  12. Basically they don't. At least they shouldn't on How Scientists Know An Idea Is a Good One · · Score: 4, Interesting
    If you know `a priori whether an idea is "good" or "bad" it will bring prejudice that will taint the results. One of the famous example is a naive Indian astrophysicist on his first trip outside India met Eddington on eve of his big presentation, in 1929. That guy explained in great detail his idea and Eddington not only dismissed it, he was scheduled to present just before this paper from that young man. He trashed the idea so much that the young man abandoned that field altogether and chose to pursue a different field [*]. Most others dismissed that paper too. It eventually garnered that young man a Nobel Prize in physics, and is the foundation of what is known as Chandrashekar Limit that tells you if a star is big enough to go supernova. That paper was discovered about 15 years later, after WW II. So in theory they should not know if an idea is good or bad.

    But that is theory. In practice, having some realistic goals based on available resources of money and time is common to all fields, not just science.

    [*] Chandrashekar was not bitter about Eddington, he credits being forced to change fields in his late 20s, taught him how to learn and he deliberately abandoned his field of study about every ten years, he continued to be productive into his late 70s. If you find the spoof paper written in his style The Imperturbability of Elevator Operators, by S Candlestickmaker, by one of his grad students, it makes hilarious reading for the geeks. ]

  13. Get student versions of analysis software packages on Ask Slashdot: Best 3-D Design Software? · · Score: 1
    Get the student version of Ansys Workbench or Ansoft HFSS. They are mainly intended for very serious finite element analysis and their geometry editing and model editing features are less complete than the full fledged CAD packages. But even the simple model editor that they include `a gratis in their analysis package is surprisingly powerful.

    If you know coding and do not mind wrangling with the a language like scheme (a derivative of lisp (which is actually an acronym (lots of irritating silly parenthesis))), you can test Spatial's ACIS. Again their primary market is selling these geometry engine to other CAD companies. But they throw in a simple, yet quite powerful, model editor.

    These packages are quite intimidating to beginners who don't care about Finite Element Analysis and such stuff. But if you persevere, you get a powerful package for free or low price. And you could do stress analysis on your model before you build and see cool pictures of stresses and strains.

  14. The weird definition of "Win" on Why Trolls Win With Toxic Comments · · Score: 4, Insightful
    I don't know what the title means by the word "win". What do the trolls win? Polite discussions inform the readers somewhat, and rude discussions polarize, almost equally it looks like from the cursory reading. So the trolls make as many enemies as they make friends. So what are they winning?

    In some certain circumstances enemies don't cost you anything and friends get you some small benefit

    One example would be a deep Red (or Blue) district politician who acts like trolls and makes as many enemies as friends. But his friends are in his/her district enemies are outside, so he does not care.

    Or even an obnoxious car salesman advertising in radio "Costoria Buick! Owner Ed has gone mad! He is stackin' 'em deep, selling 'em cheap"!. Yeah, that guy is irritating, but you might still remember the name of the dealership, and the irritated millions do not bother him. The few sales leads that he does get is enough for Ed Costoria.

    So I don't see the internet trolls as winners, but the sites hosting them as losers.

    I bought a chromebook a week back and was all gung-ho about it. So much so that some AC called me shill.

    Yesterday I was showing to my friend and logged into my gmail account in Chrome running in his windows box. Impressed him with my two factor authentication, text message to my phone and all that. But made the mistake of clicking yes to "synch" when prompted by chrome.

    It brought all my bookmarks on to his machine!. So I deleted them in his machine, then they were also gone from my account in my Chromebook. Not only that all HIS bookmarks were on my machine. I deleted them. Then I found all my saved web passwords were on his machine! This screw up after bragging about two factor authentication. He uninstalled Chrome and reinstalled to get rid of all remnants of anything. I lost my bookmarks. Apparently this is a common problem with Chrome and google synch and it has been widely reported and complained about. Still the dialog asking for synch did not give any warning that my passwords and bookmarks and auto-completes are being downloaded into a new machine. I am very disappointed by Chrome and google.

    Luckily he is a friend, and I never store any serious passwords in my gmail account. So no serious harm done. Now where is that AC who called me a shill?

    Boots very fast, less than 20 sec. Sleeps / wakes up instantly. Battery lasted three hours. No click buttons or scroll bars in the touch mouse pad. Two finger touch and click is "right click". Two finger click and one finger move is click-and-drag. Two finger swipe is scroll. What does one finger swipe do? Highlight maybe. Not sure. Functions keys to cycle through browser windows, full screen/part screen, back/forward, volume control, pop up app panel etc. App panel has the aspect ratio of a smart phone and pages and pages of icons. Bright screen. 13xx x 7xx . Battery meter is calibrated in minutes remaining. Approximate minutes I should say. We need to ask New York Times how accurate the battery meter is. That is about it. I still think it is a steal at 200$ for a plastic hard disk based net device. Decent at 250$ for solid state drive. Dont know if Samsung 250$ thingie is aluminum or plastic.

    Quick review: When there is a network connection, it is a solid browser. It synched with my Chrome browser customizations from my previous use of chrome using windows or linux boxes. Including flashblock and adblock.

    But what about off line? Google docs off line lets you edit documents and presentations off line. They sync when you get the connection. When it first came it had no off line edits. Then they have introduced doc and presentations. Spreadsheets would be next I guess. Or may be not. Gmail offline can be customized to keep last so many days worth of email in the local cache. Google calender works off line, ( I think, need to go back and check.).

    Off line music player works, off line video play back works. Source of the media could be the internal drive or any USB drive, including the USB powered hard disks. Kindle off line reader works, three books cached very quickly. Apps exist like "Read this link later" that works off line.

    So off line, you can watch video, listen to music, read books, cached web pages. You will have read/access to all the google drive docs. And write access to docs and presentations. I think for 200$ it is way more than what I expected.
