  1. Re:Again, PR failure but engineering success on Scientists Say Goodbye to Philae Comet Lander (cnn.com) · · Score: 2

    What? It was almost a complete failure. It didn't land how or where it was supposed to. It couldn't drill or sample like it was supposed to. Nothing worked except the camera and that didn't work for long because they landed in a place where the batteries ran out.

  2. Re:Cheaper and Faster???? on Windmill Blade Molds 3D Printed By National Labs (energy.gov) · · Score: 1

    I've made smaller molds (several feet) using both techniques. For this application milling the molds from a high density foam will be much cheaper. The 3D printing is just a gimmick. I've made molds using 3D printing ABS and one of the nice features is the epoxy resin doesn't stick well to the ABS. So you can just use Acetone to seal the printed surface and use it at a mold with very little prep.

  3. Re:Math is a Chore on An Advanced Math Education Revolution Is Underway In the U.S. (theatlantic.com) · · Score: 1

    Depends on the textbook. We decided to start homeschooling and I'm using a Saxton Algebra Book. I love it. Each chapter increments what was done previously and there are some examples worked out followed by a handful of problems on that material. Then the problem set is 30 questions that can go back to the beginning of the book. Each question has the reference chapter in parenthesis in case the child needs to review it. That way you are always checking retention.

    After an initial rough period transitioning from the Common Core approved Hardcourt book he is doing wonderfully. Takes him about an hour each night to do math. We test once a week on Friday and it covered material that was introduced 2 weeks ago so there is plenty of time to practice and master it.

    So much better than the cram for 1 week, test and repeat.

    I've been using the same strategy for 20 years now based off Harry Browne's Failsafe Investing. 25% each in S&P 500, Cash (FDIC Money Market), 25-30 year Treasury Bonds, Gold Bullion Coin (Eagles). Every year rebalance if any one goes +/- 10%. New additions go to cash.

    That's it. Very simple, good long term returns 10% and low volatility. Even 2008 was a small gain.

    A strong currency is always in a nations good if you the define the nation as all of the people. It is not good for people that want to steal wealth from the populace for themselves. To weaken the currency new currency needs to be created. This new money cannot be distributed in any fair way. So what happens it is given to those in power to help maintain their power.

    A nation with a strong currency will reward savers. You won't have to work as much. A weakening currency will continuously steal wealth from you requiring you to spend it or lose it. It will also force you to keep working as you cannot maintain your standard of living without it.

  8. Central Banks Responsible for this on World Bank Says Internet Technology May Widen Inequality (nytimes.com) · · Score: 5, Insightful

    I worked in automation equipment for many years. Companies would typically come to use when they needed to expand capacity. When we would work up a quote we would look at their current process and come up with several options from very simple conveying system with manual tool stations for the operators to fully automated systems. Obviously there was a huge capital cost difference between these options. Two big factors that went into the recommendation were the labor rates and interest rates. The companies were looking for a specific return on investment. In a free market when interest rates are low and labor rates are high due to low unemployment and lots of savings it is better to automate as the interest on capital costs are low. When the interest rates are high and labor rates are low due to high unemployment and low savings it is much better to hire people and go with manual stations. This is as it should be and would lead to sustained growth.

    But when the Central Banks lower interest rates way below the market rates it makes automation cheap no matter what is going on in the economy. This is the situation we are in. It is cheaper to automate even though labor rates are low and there is low workplace participation. Allow rates to return to their market levels and this will change and we can go back to sustainable growth. Of course we won't do this because it would hurt the Wall St. Banks and politicians pocketbooks.

    Ad an experiment I thought it would be interesting to run the low speed fan and compressor 24/7 during the summer and chart the temp and humidity and see what the bills are. The temp would go down at night but probably not too low to be uncomfortable and when it heats up during the day at least it would be dry.

    I live in Florida with a high efficiency A/C (19 Seer) and I noticed very little savings $10/mo at the expense of major fluctuations in temperature and coming home to a hot humid house. The upstairs and downstairs would have strange set points that made one unit run all the time (at full power).

    I sold them online and have cheap thermostat with 4 set points during the day. The units run nearly all of the time in the summer but on the low power, high efficiency setting. The house is much more pleasant at very little extra cost.

    You don't fight wars with the militia. It is the force you conscript to create your Army when you have a war. The US Army was tiny prior to WWII. The men of the time (especially those in rural areas) were very well trained. When war was declared the professional officers of the Army were combined with the conscripts from the militia. After WWII most to the conscripts returned to civilian life. The same for WWI.

    "A well regulated militia being necessary to the security of a free State, the right of the People to keep and bear arms shall not be infringed."

    What people on both sides don't understand is the first part. What this means is that INSTEAD of having a standing Army which the colonists lived in fear of and was required to enforce tyranny, it was necessary to have a well regulated (armed and trained) militia. If you want to be free and secure this is the only option. If you have a standing Army you will be secure but not free. If the the citizens well armed and trained you won't have security.

    The best example is the modern world is Switzerland. Everyone is well trained and armed. But the professional full timers in the army are only about 5% while the rest are the militia.

    This view is backed up by the Powers of Congress which make a difference between the Navy (which was intended to be permanent) and the Army (which was only funded for 2 years at a time and only called up from the militia when needed).

    Being an expert in a particular area means that you have neglected learning in other areas. You only have so much time to learn things. To many technically oriented people all of the vagueness of social interactions is not logical, it cannot be derived from first principles. If is culture and it is that way because that is the way it is. This isn't interesting to many technical people so we spend our time on more interesting things. So while you may bitch that technical people don't have social skills what you really mean is that instead of learning social skills they spent that time becoming an expert in a technical field. You have spent your time learning social skills and then complain the reason you don't have technical skills is because those with them are mean. That's like me after spending my life learning English moving to a Spanish speaking country and bitching that I could learn Spanish much easier if all of these people would just learn English to help me. Sorry but that's not how it works.

    I am an excellent mechanical design engineer that has spend over 20 years learning and honing my skills. This includes studying in my spare time and even my hobbies contribute in some way. Even entertainment I like watching "How it's made" so I can see examples of automation equipment for ideas. Some bosses have asked me to put together a 30 minute talk to help people learn to become a good design engineer. I laugh (maybe my lack of social skills) and say I only need a minute. I'd tell the people to dedicate their lives and spend 20 years learning this stuff and you can be just like me! Most people don't want to do that and spend their time with other things. That's fine, but don't come complaining that I lack budgeting or scheduling skills. No kidding, I have no interest in management. That's your job.

    This is where property rights make things easy. It's the employers property so it should be their rules. The employee can choose to work their or not. If the rules are too draconian then you won't have good employees and your business suffers. The problem with a one size fits all solution is you have no idea if it is the preferred solution. With a market of ideas multiple ideas can exist and people can chose to live with those they like.
