    Clevo is a Taiwanese Manufacturer of High End Laptops. I do visualization research and use a 6 core Clevo laptop with a quadro card because it was 6 months ahead of Dell offering a similarly capable machine.

  2. Re:Firefox? on Crowdsourcing Ancient Egyptian Scrolls · · Score: 1

    I'm in firefox 5 in Linux and had no problem with the app except that the contrast on the pictures was so poor that I had to open them in GIMP and adjust the levels to even see markings on the scroll. 10 times the resolution would be needed for me to make much more of it than dark outlines of scrolls.

    Take a look at Aspen Aerogels. They make an apparently cost effective aerogel building insulation. They also make variants for use as high efficiency furnace insulation.

    I was googling for Baez's crackpot scale and I found a fascinating paper by Greunberger at the Rand corporation based on a discussion he had with Nobel Laureate Richard Hamming on crackpots. It's a more serious crackpot detection paper and it's excellent reading. http://www.rand.org/pubs/papers/2006/P2678.pdf If schools taught the contents of this paper, critical thinking skills would be improved.

    Not all liberal arts colleges are the same. I went to Harvey Mudd College which bills itself as the liberal arts college of science and engineering. I can still recite a lot of Chaucer and Shakespeare. By the same token, HMC was listed in Money Magazine as having the most financially valuable Bachelors degree in America. See: http://money.cnn.com/2010/07/22/pf/college/highest_paying_college_majors/index.htm?hpt=T2 Studying humanities as well as engineering allowed me to relate better to human events and command a knowledge of history and mathematics that I have found isn't shared with other engineers I know. Despite having only a bachelors degree, I now do research work in image processing which is on the verge of being commercially licensed. I didn't even study image processing in college: I taught myself.

  7. File a Civil Writ of Replevin on Retrieving a Stolen Laptop By IP Address Alone? · · Score: 2, Interesting

    If your state has replevin laws on the books file for a civil writ of replevin. This writ order the sheriff to seize such property so it can be brought to court to determine the true owner. You have to post a bond for the value of the property but you get that back when it's proven to be yours. This is only legal for items with specific identities like serial numbers. You cant replevin 100 lbs of wheat because there is no way to prove which wheat it is. I never actually did this but considered it when someone stool some of my tools and I knew who it was and had witnesses.

    GPS coordinates are defined in the WGS84 coordinate system. (I spent 3 years writing the coordinate transformation library for the SEDRIS Spatial Reference Model: ISO 18026). See http://standards.sedris.org/#18026 What you are doing when computing the geodesic is solving an elliptic integral. There is a lot of literature on it and generally speaking, there are short, medium and long line solutions depending on how far apart your points are. Different solutions are used in the three cases because many terms in the longer cases are too small to be relevant in the short cases. See ISO 18026 OPERATIONS Section as well as R.H. Rapp Geometric Geodesy Part 1 https://kb.osu.edu/dspace/bitstream/1811/24333/1/Rapp_Geom_Geod_Vol_I.pdf pg 71 and https://kb.osu.edu/dspace/bitstream/1811/24409/1/Rapp_Geom_Geod_%20Vol_II.pdf page 1

    I've never heard of Docky or Gnome Do. Tomboy is alright. Banshee never works for me. Uninstalling Beagle is my first priority on a new machine as it sucks up enormous amounts of resources for marginal if any use. I've also never heard of Unity3D. I've been using linux since the mid 1990's. For me, these results speak for themselves in terms of the value of Mono.

  18. Dispersion hardener on New Heat-Reduced Magnetic Solder Could Revolutionize Chip Design · · Score: 1

    This sounds like this would use a very high intensity high frequency magnetic field tuned to make the iron particles resonate and heat the material. I suspect it would be like normal solder with some iron particles. As a bonus, small iron particles would act a a dispersion hardener in the alloy. It's also quite possible that the particles are actually nanoparticles of iron rather than micrometer sized ones as this size range works better as a dispersion hardener.

  19. Re:Could some one explain the following then on Scaling Algorithm Bug In Gimp, Photoshop, Others · · Score: 1

    He is right that the eye has a logarithmic response. Unfortunately, most digital sensors have a linear response. In this sense he is wrong. If you scale sensor data, the linear scaling is right. I suspect his anomaly is due to overflow in the linear calculation and the fact that the logarithmic calculation won't overflow. For scientific data, there's no way one would want his scaling calculation. If on the other hand, you scale a gamma corrected image from a linear sensor using the ordinary linear scaling I can see that you might get the problem he is describing.

  20. Re:Call wikipedia on Perth Game Company CEO Takes IP By Night · · Score: 1

    Using the word engineer on this side of the pond generally means that you went through an academic curriculum that would allow you to pass the first licensure test required of a professional engineer. I believe the reason that there is concern about the word engineer is due to the American Society of Mechanical Engineers wanting to certify engineers designing steam boat boilers in the 1800's when unqualified people designing boilers caused many fatal explosions. In many U.S. states, it is against the law to call yourself and engineer of any kind if you are not a Professional Engineer, the U.S. equivalent of a Chartered Engineer. In the State of Alabama where I live, I get the newsletter for the Alabama Board of Engineers and Land Surveyors and there are half a dozen cases a year of people being prosecuted under civil law for practicing engineering without a license or using the word engineering in a company name without employing a Professional Engineer. You Brits have your CEng designation, we have the P.E. designation.

    The therac 25 incident also involved a lack of interlocks. The previous model to the therac 25 had hardware interlocks which would never have allowed the shutter to stay open the way it did in the incident.

    I have been working on doing a machine tool project with an Italian engineer for that last year. One thing I noticed is that there are good sized tariffs on machine tools imported from Europe into the U.S. while there are no such tariffs against machine tools imported from China.

    I spent some time at the David Sarnoff Museum in Princeton, NJ and it should be noted in the context of your argument that much of the early research on liquid crystals was in fact done at the David Sarnoff Laboratory of the RCA corporation (now Sarnoff Corporation) in the U.S. circa 1962-1964.

    I do agree with you conclusion despite the above arguments: I too think we can do fine without the H1-B visa folks.

    I think people justify the argument for H1-B's by saying that there are a lot of code monkeys required to write the endless GUI software needed for public consumption. With all of the countries in the world, it is easy to get someone who was trained to a moderately high standard for the same cost as a local entry level coder. It doesn't take more than a few calls however from the last local hires back to friends still in college explaining that H1-B's have all the entry level jobs in order to decimate the number of CS grads produced in the U.S. In the short term, the company gets more work done. In the long term, I suspect bored H1B's with masters degrees will be sitting in all the entry level slots which might have produced future CEO's and engineering directors if the people were thought of as plants to be nurtured rather than resources to be exploited. In short, maintaining an organization is about the process and I think H1-B's destroy the process that made the great American engineering organizations by allowing companies to exploit workers in the short term without the need to grow them for the long term.

  25. Re:Why extended warranties are useless on Extended Warranty Purchases Up 10% This Year · · Score: 1

    What he is saying is that electronic system failures often follow the Weibull distribution. It is a mathematically precise statistical distribution that was developed to model such things as equipment failures. The Weibull distribution has many parameters and the curves can look like many things other than just a bathtub. What the exact time distribution of failures is requires a lot of data which either has to be estimated from previous systems or calculated by determining the joint cdf of component parts which were tested individually.

    I've never seen components that had enough data to assume anything other than a normal distribution and the joint cdf of normal distributions is not a Weibull distribution. This would lead me to believe that a Weibull distribution is probably fit empirically from historical data. Given that this is actually work, I sometimes wonder if they use a seat of the pants approach instead although there seem to be a lot of stories about devices failing right after the warranty is over.
