Comment Re:Kill dogs, why not people??? (Score 1) 179

Anything that kills a living organism is potentially a problem for humans. Only a small % of man-made chemicals have been rigorously tested for causing cancer; but then would you volunteer for such a study. I thought so.

Lead, asbestos, formaldihyde, weird solvents and reactive chemicals have been mostly eliminated from consumer goods with good reason.

Just stay away from as many chemicals as you can. Drink from glass cups/glasses. Wax coated paper cups, no. "Slug bait," no. Fast food, well virtually all fast foods have an anti-bacterial agent (calcium probinate) in them and it can muck up peoples digestion if they are sensitive and who knows what else.

The most obvious are those associated with medical insurance, automobile & fuel requirements, electricity costs and added costs to electronics & devices for Energy Star & trace & potentially hazardous metals, like lead.

The increases are insidious in that most are built into requirements that the retailer, distributor and user never see as an individual cost. Some are indeed needed, like eliminating lead paint and asbestos. Others like using coal in power plants are questionable, but dozens of coal plants are due to be forced to close prior to the summer heat wave period of this year. That is punitive on the population for questionable benefit.

When you look at the decrease in dollar income over the last six years, coupled with now about 90 million adults not in the labor force (highest since early 70s), the effect is understood more, since it is factually true that % of population working and average income is down.

Comment Evolution-De-Population of Rural America (Score 1) 110

Technology changes are making the mega-city areas more desirable. Is rural America going to be slowly boarded up?

Given the wholesale changes since 2000, it is easy to see that the mega-suppliers/dealers, Amazon, Walmart, drug dealers, etc, are only efficiently available in the denser areas, but now the (Un)Affordable Care Act is decimating smaller town hospitals along with the increasing difficulty of making small retail businesses profitable given everything from increasing regulations, taxes and lack of (easily) repairable products. UPS & Fedex for small towns are the only saving grace.

The only given is change, and cities have been abandoned before the time of Christ.

Today, technology is the mover and shaker, but will it reinvigorate the small town?

Physics can be huge data sets and FEA type programs, in which case you get the highest end laptop you can afford. Otherwise, pick a laptop known for reliability with quick service when something goes wrong.

Me, I would rather have a MacBook Pro which I can run Window, Mac, Linux, etc. Yup, Dell's workstation class laptops, the M2800 to M6800 systems, but they are MacBook Pro type prices.

Comment "Viewing" Viewing Evolution in real time (Score 1) 205

Steve Jobs had a habit of looking 10-20 years into the future for where Apple would move to in product use. Cable with 300 channels is doomed and SJ saw that. Why do I need a TV to view the one or two programs I want to see at night? Why do I need a "big screen" for news?

Young people are more interested in mobile and sharing clips, than most older people and that is evolution. Older retirees often look at TV as a companion or avocation in lieu of something/anything else to do.

I see cable and even fixed mega-size TVs as dinosaurs. You want a big screen, go to a movie house.

"Journalists" ought to learn more about what they write and posters ought to do the same. "Man makes working model of 5 speed transmission" would be a better title. But what was the point?

RP metal parts have layer build thickness and microdroplets forming the parts meaning they have surface finish and tolerance issues that will never be solved to make a high volume "production" part with required properties in any economical time span.

The finer the build layer, the better the surface finish, the longer the build, but there is still a limiting surface finish and tolerances that are not good enough for high load and wear situations. Then comes the issue of heat treat hardness, which current materials can't handle. Can't do that with materials used now as they don't do steel alloys yet.

RP is good for certain demo and non-toleranced or critical but complex parts that can justify the extra finishing in the limited materials available, but those are far and few between.
