Comment The FedEx bomber (Score 1) 52

Google is always doing weird experimental shit. So this is not news.

What would be news is what FedEx or UPS are working on wrt drones. Imagine a FedEx jet flying high over a city, its bombay doors opening to spill out a fleet drone quadcopters that deliver the goods to designated rooftop landing pads. Imagine a world where technology is paying as much attention to the last 2,000 (vertical) feet of delivery as we do to the last mile of communications.

Yeah, because what was good enough for the Roman slaves and medieval serfs is obviously the best life style for everybody.

Look to our roots in hunting/gathering, and you find there was no set pattern for sleep. When picking berries, you slept in the shade when it was too hot or at camp when it was too dark; otherwise you picked while watching the sunrise and picked while watching the sun set. When the smelt were running, you scooped up fish in the moonlight, cleaned fish as the sun rose, gathered wood and greenery for the smoking fires in the morning, and took long siestas during the heat of the day.

Our ancestors may have averaged 8 or 10 hours of sleep in a day, but for the most part it was in bits and pieces. Mostly no more than 4-6 hours at any one time, with the rest in siestas or naps as tasks allowed.

I've done this for years, and didn't even know it was a thing. Seems to work.

Works for me too, especially when bumping into dead ends doing creative work.

I'm a writer; I can put in a solid day's work on the proofreading and minor editing/revision aspects, but sometimes spend days or weeks trying to find a good point of view for a scene, or effective way to present character development. Best thing when realizing I've just spent half a day writing crap: have a cup of coffee and nap 15 minutes.

And yet involving yourself or your company in the Microsoft ecosystem continues to be a waste of your resources.

For all core business functions, the Linux ecosystem, despite its pimples and occasionally awkward behavior, now offers the better current and future value. And it is rapidly completing its maturation and as it does so its complexion is clearing up and it is continuing to replace its remaining adolescent behaviors with more sophisticated ways of getting along in adult society.

Microsoft's best long term strategy is to convert its software to open source and merge it into the Linux ecosystem while developing support services as its primary source of revenue. That has worked for IBM; it could work as well for Microsoft. But it means that Microsoft needs to embrace FOSS and begin extinguishing its own proprietary software while learning to dance to the music the rest of the world is tuned in on (rather than dancing to whatever it is that is that it has been playing on its own private ear buds).

Flamebait? Or an insightful summation of the situation? You decide. Since even the author of this post doesn't know which he has done.

Comment Re:Dobsonian (Score 1) 187

All I would add to this is that from my experience as a kid with a 4 in reflector in 3 or 4 foot cardboard tube (good EQ mount) is that high power eye pieces may not be very useful, due to vibration in the tube. So I would suggest getting a low power and a medium power eyepiece to start, and being very careful about buying high power eyepieces.

Unfortunately my experience was too long ago for me to remember what magnification my eye pieces were. But others might chime in...

Comment Re:Dobsonian (Score 1) 187

The problem mentioned in parent post was not due to the type of mount. But due to a mismatch between the quality of the optics and the amount of money spent on the mount.

A 10 inch reflector needs to be mounted on a stand weighing several hundred pounds or there is not enough mass/inertia to make use of the 'scope's capability. There will be too much vibration just from persons walking near by.

You can't put fine optics on a cheap mount of any kind and get acceptable performance. And any mount that would be knocked off calibration by a slight bump is not good enough for a 10 in mirror.

I disagree with parent. An equatorial mount is the way to go, short of a computer controlled motorized mount of any kind.

The problem is not that of initially pointing the 'scope at the celestial object. Anyone can do that with either type of mount. The problem is tracking the object after it is found. An equatorial mount that locks the scope to the object's track is the only way to go within an affordable price range.

I was 12 or 13 yo when my Dad decided that I showed enough interest in astronomy to be worthy of owning a telescope. My birthday present that year was a used 4 inch reflector on an equatorial mount with a couple of eye pieces. I loved that thing.

I can attest that a 13 yo can learn to use an equatorial mount with ease, including aligning it properly with a magnetic compass, which also involved learning to adjust for the difference between magnetic and true North. All of which was fascinating. I learned all this without adult supervision (Dad was not into astronomy), and I am certain that a motivated younger child could easily learn all this with good adult direction.

The frustrations I encountered with this first telescope experience were in aligning the mirror and aligning the spotting scope with the main tube. In retrospect it would have been much better if an adult had done those things for me. Other sources of frustration were that the spotting scope's crosshairs were not very visible in the dark, and that scope's tube was not rigid enough for the higher power eyepiece to be of much use (too much vibration and jitters). These details should probably be considered when making the purchase.

Don't discount craigslist, etc, as a good source for a used telescope. Some who start with an entry level 'scope lose interest and sell their's, others upgrade to better equipment when they can. A second hand 'scope from someone who is spending beaucoup bucks on a better replacement is likely to be in excellent working order, and could be a really good deal. Plus, often the seller would willingly give a potential buyer a free night time demo, with rings of Saturn or moons of Jupiter...

Oh yeah, there is prob'ly an amateur astronomy club around you somewhere. They put on star gazing parties where a person could look at a number of different set-ups and get a lot of info from their owners.

I don't think I will end up agreeing with parent post (that the removal of humans from an urban region would foster genetic diversity among the remaining species), but this idea is something to think about. If I had mod points at the moment I would give parent post a "+1 interesting". It does not deserve the "-1 troll" it currently carries. An odd concept but not a trollish one.

If the UX is really good, you can let the user documentation slide somewhat. You can also think about presenting the basic user docs as a wiki and encouraging your user base to expand and expound on that. Editing user contributions will be a heck of a lot easier than writing from scratch (you can start things off by just publishing an outline of what needs to be covered).

IS 2+2 REALLY 4?

Well, the concept of "two", or "twoness" is imaginary. It has no physical, chemical, astronomical, or any other scientific qualities. So it is outside the set of things that are "real". "Twoness" only exists in your head; it is at best an artifact of your perception of reality. But such artifacts are not real in themselves.

There is no reason to believe that doubling something that is not real will make it real. That would not be logical. (Invoking the Spock argument.)

Thus "2+2" does not "REALLY" equal "4" in any place other than in your head.

That you can use the totally imaginative structures of "language" to construct a pattern of sounds or pixels that evokes in someone else an imaginary statement of "2+2=4" is something to wonder about, but again no part of that process has any real component. It is all imagination. Highly discipiined imagination in some cases, such as QED, but still just imagination. Not real in any meaningful sense of reality.

Comment Re:Oh good lady, and lord. (Score 5, Insightful) 225

we'd like to have non-baryonic fairly massive (so relatively cold) particles. Dark matter is anything that doesn't interact with regular matter via the strong or gravitational interactions. Neutrinos don't.

More and more I'm getting a feeling that science has been down this road before. That our understanding of subatomic particles and the distant edges of the Universe is similar to the pre-Copernican use of epicycles to understand astronomy. That the search for dark matter (and probably string theory too) is a search for that final missing epicycle that will make the model work just right.

I think we need to look for a Galileo or Copernicus who has some whacky, undeveloped alternate concept that if only we could change our point of view, we would see that it makes everything so much more clear.

Comment Re:Self-awareness (Score 1) 115

The Earth-Moon barycenter is very nearly outside of Earth itself (it's about 0.75 Earth radii from Earth's center), so let's not get too high on our horses...

And the Earth - Moon should be classified as a binary planet. They are in such an intimate dancing orbit with each other that neither one can be adequately described without refering to the other.

This is more than a semantic squabble. Any exoplanet that is likely to support life as we know it must not only be in the Goldilocks zone, it must also have a companion close enough to create tides (and tide pools, and generally act as a celestial stirring rod).
