  1. Was this unsafe following? on Tesla Says Autopilot Was Engaged During Fatal Model X Crash (theverge.com) · · Score: 1

    The driver had set the following distance at the minimum which sounds like an unsafe decision. I have a Subaru with smart cruise control which allows setting the follow distance which is speed dependent. I set it on the maximum which is very close to my normal follow distance. Any less would seem too risky for me to respond to unexpected events ahead. I don't know if the stated 150 meters was sufficient warning based on his speed (unknown?). Clearly the driver should have been driving. 150 meters is likely sufficient distance to reduce speed enough to survive. Still the software should be studied to see why it allowed a car to run into a concrete divider at high speed. If there is not sufficient visibility the autopilot should refuse to drive and allow the driver to take his life in his own hands. Maybe in a few years the autopilot will be better than a human and simply not allow the car to be driven when it is unsafe.

  2. Re:Unless NASA is paying people on NASA Spends 72 Cents of Every SLS Dollar On Overhead Costs, Says Report (arstechnica.com) · · Score: 1

    I agree. I worked for NASA for several years. There were NASA people doing useful work. I did computer programming along with several others in my small group. At the time I thought it would be more economical to hire more government workers. The purpose of a government agency is not simply to transfer money to private contractors, so the presentation is flawed.

    The speeds offered are 30 down/20 up or 100 down/50 up (in Mbps). So it is about like cable internet in the US.

  5. 3D for scientific data display is also over-rated on 3D TV Is Dead (cnet.com) · · Score: 4, Informative

    I have worked with a couple of 3D displays for scientific visualization. The university I worked for had a fairly expensive system with an 8 foot by 10 foot 3D display "wall". It was great for demos, but after a year or so of mostly demos, it was largely abandoned. I also got a set of 3D glasses for a 20 inch CRT system and added 3D support to a program I wrote for a physicist friend to display movies of particle simulations. Most of the benefit of seeing the 3D structure could be obtained by simply rotating the scene or movie. Another friend said that chemical display software frequently uses a "wobble" option to add some 3D-like effect to molecule displays. I added a wobble option to my program and it worked pretty well. My experience was that people didn't care enough to walk down the hall to use the big 3D wall and even with 3D glasses in his office, my physicist friend didn't bother. It's not much of a surprise to me that 3D TV is largely a bust. It is cool for a demo, but it seems destined to be used only for demos. Maybe with 3D systems not using goggles or perhaps with lightweight glasses there will be a future for 3D displays. I hope so, even after seeing no one really using it.

    Your link was for federal income tax. There are many other taxes which hit the poor and up their percentages drastically. They pay sales tax on a large portion of their income. They pay gas taxes. They must buy car tags and pay a variety of other fees. Either directly or indirectly (as part of their rent) they pay real estate taxes. I found 1 site stating that the bottom 20% pay about 10.9% in state and local taxes. Overall this probably means about 13% vs 30% which is progressive, but the top group is quite mixed. You might recall that Mitt Romney's reported income tax rate was 14% for 2011. My guess is that the richer you are the lower your income tax rate. It is quite possible that Mitt Romney's total tax rate would be lower than many people making $50K per year. For those at the maximum taxable rate for SS, they would likely pay over 20% total taxes. I personally recall many years back when Jimmy Carter was President there was one year when he owed no income tax and donated $5000. I paid more than that on less than $30K. I believe the top marginal rate was 70% back then, but I never really believed that people paid 70% tax on any of their income. The tax breaks for the rich are not really available for the vast majority of us.

  8. Re:Bad analogies can do a lot of damage. on Oracle V. Google Being Decided By Clueless Judge and Jury (vice.com) · · Score: 1

    That's a good analogy. I suggest that the people involved could understand an API vs the implementation by observing the prototype for a function and then the actual function. They don't need to understand the code. They need to know that the provider for the implementation allows people to call the function by observing the API and not the code. It is simple enough to discuss without analogies. The decision needs to be made on the real thing and not on analogies.

  9. Re:Not really news at this point on Another Slew of Science Papers Retracted Because of Fraud · · Score: 1

    Good suggestion! Articles could be rated much like SlashDot. There could be any number of reviewers for an article. Some reviewers would have more weight than others. Knowing that a large number of reviewers think an article is worth reading is good enough. This need not cut out the publish or perish game, but the rules would need to change.

  10. Re:seems about the same on Ask Slashdot: Why Does Science Appear To Be Getting Things Increasingly Wrong? · · Score: 2

    The question of teaching quality is a part of the problem. Almost no university in the US judges professors based on teaching. They claim to do so, but the tenure decision is primarily a judgement of publications and external funding. In my case the quality of publications was largely irrelevant. I assume that better universities judge quality of research, but I haven't been there. We need to seriously consider having teaching positions for PhDs in addition to research positions. I am not sure if the institutional motivation is money or prestige, but I think that many schools short-change students to pursue research. Expecting research and funding degrades teaching. Better teaching will help to produce better research.

    I also like the idea of researchers not being under such huge pressure to survive. Pressure, along with incentives, contributes to the willingness to take shortcuts and to publish made-up results.

    My last comment is that publicly funded research should not result in private wealth. If the public pays for the research, we should get cheaper prices on the goods. Perhaps there could be a system where such products are public domain and available for all to develop and market competitively.

    I like this suggestion. There could be revisions by year, month and day. So 15.2.13 would be Feb. 13, 2015. There would be a need for a few times with multiple releases in a day. This could be done with an optional sequence number: 15.2.13-3 for the third release for 2/13/15 (or 15/2/13 for a more rational date format). At least the version numbering has some meaning. It's almost meaningless to me to see 3.16.0-30 as a version number.

  13. Re:The Middle Class is the Bedrock of Society on Bill Gates: Piketty's Attack on Income Inequality Is Right · · Score: 1

    There is some limit to the amount of physical resources on the Earth. There is likely a smaller limit of the amount of resources which can be harvested without destroying the planet's ecosystem. Malthus was basically correct in his assessment of population growth. We can probably feed 10B people but not 100B. There are other types of resources which are more mental in nature to which the limits are harder to assess. Over time we can increase the ability to amass mental resources. Of course, it may be possible to move into space and then perhaps there is no limit to physical resources. I do agree with your concept of balance. We can be socialistic enough to provide for comfortable living for the masses while allowing those with ambition and talent to live more comfortably. We will always have wealthy people. In my mind the proper balance includes a comfortable, though not luxurious lifestyle for all, with enough economic mobility for people to be motivated to work. The top 1% can live like kings without the 99% being serfs.

    It's never been a nightmare for me to maintain a Linux computer remotely. I would never suggest having non-savvy people keeping a computer up to date with Linux, Windows or OS X. Kubuntu will keep itself up to date if set to auto-update and ssh can be used to remotely manage the computer if needed. This might be a poor solution if the original poster has no Linux experience. I suppose the fact that the question was asked should have been a clue that this wasn't a Linux-savvy person or there would have been no question. Given the assumption that the original poster was a newb, then you might be right. Hopefully experienced help is available for whatever choice is made.

  15. Linux runs Skype and Google+ Hangouts. I can't vouch for Facetime. Ubuntu works well with automatic updates and can be administered remotely as needed. The user interface needs to have icons on the desktop for the needed programs. I would use kubuntu since I have never liked Unity.

    I have been working on an IDE (primarily for assembly language) for almost 2 years. It runs on Linux, Windows and OS X, using Qt for the GUI components. I edit exclusively in vim on all 3 platforms and compile with g++ on Linux and OS X, but compile with cl on Windows. Well, truthfully I use the Qt qmake tool to prepare a proper Makefile for the OS and then use either make or nmake. I debug typically under Linux and generally use the qDebug function. I will use gdb for a few commands here and there. I haven't yet needed to use the Visual Studio GUI or debugger. Editing with vim is much more efficient than nearly any IDE. I have done a little VB and liked IntelliSense there. I haven't tried it with C++. I suppose I need to add: "Stay off my lawn."

  18. Matter-Antimatter Explosions on Why Are We Made of Matter? · · Score: 4, Interesting

    I wonder if it is possible that the Universe has some regions of matter and some of antimatter. In between there would be mixed regions and the resulting explosions could tend to keep the different regions separate. Initially asymmetry in the distribution would leave some small regions of each type. The m-am explosions could force separation and a certain portion of the matter regions would merge with other matter regions and the same for antimatter. This seems like a fairly obvious thought, so I assume that it has been considered and ruled out. Why or why not?

    Anyone with a lot of money and little computer security knowledge needs to hire someone to set up their computers and teach them safe practices. It would be worth several thousand dollars to a milliionaire to avoid the sort of problems Ms. McWhorter encountered. Perhaps she is not rich, but she has won a Pulitzer prize for writing. I think she could afford to try harder to be safe. Ideally an operating system should protect the user, but it is practically impossible to write complex software with no errors. People should be suspicious when their operating system comes with a time trial of anti-virus software. The fact that such software exists, makes it pretty obvious that the system is fragile. Ms. McWhorter writes well, but is clearly not a computer security expert. She needs help with her computer and on-line affairs.

  22. Eugenics will happen on Root of Maths Genius Sought · · Score: 1

    Currently it is politically incorrect to consider eugenics. I personally think that our view of this will gradually change as our knowledge of genetics increases. Suppose it becomes easy to select traits like athletic ability, appearance or intelligence in children. Some people will certainly try to give their child an advantage in life. It will happen like steroids in sports. Once some children are born with better traits, others will be tempted to do the same with their children. The ugly part of eugenics is association with racism. As long as we don't have categories of people forbidden to reproduce, it should be politically acceptable. It's not inherently evil to do something to opt for smarter or stronger children. Probably there will be successes and failures, but I think people will do it. For me I wonder what people would choose: intelligence, beauty, strength, ... With respect to math genes, it is currently hard to find a job with a Ph.D. in math, so there isn't a huge need for more people with good math genes though a few geniuses might be useful. My guess is that different folks will choose different traits and that the human race will become more diverse. People will continue living in interesting times.

  23. Keep it simple on Ask Slashdot: Best Language To Learn For Scientific Computing? · · Score: 1

    Your best bet is to use C. It is highly efficient. If possible use computational code like the Atlas BLAS package. This code will run circles around your own code no matter what language you use. You already know C and moving to C++ is a major problem. All the other languages are distractions from your purpose.

    If possible run multiple, independent processes rather than writing parallel code. That can be a major ordeal.

    If your goal is to process data as opposed to learning elaborate programming techniques, keep simplicity in mind. C is a very powerful language and you can reach maximal efficiency for many problems using Atlas BLAS and multiple processes. If you goal is to get a degree in CS, ignore what I've suggested.

    I worked for NASA about 30 years ago and experienced a similar situation. The plan was that NASA employees were supposed to write job orders for Lockheed employees to work on. There were several of us NASA people who generally wrote Fortran instead of job orders. We were pretty good and this seemed reasonable to us. Now Lockheed did have some good programmers too, though they were only about 75% successful with their hiring. I did write some job orders and once or twice I ran into someone who was unproductive. Overall it worked fairly well, though I thought it would be better for all involved to work directly for NASA. I don't think that the government can count on successful contracting any more than successful government employees. If government employees are only paper pushers, then we have a large amount of wasted effort in management.
