shooting which requires both close-up vision (to see the signs) and long range vision (to see the target)

Unless your distance vision is *really* bad, to the point where you can't make out the target at all, distance vision doesn't have much impact on shooting. In a proper sight picture you should be focused on the front sight, and you also need the rear sight to be clear enough that you can verify precise alignment. The target will always be blurry, so having it a little blurrier because of nearsightedness isn't typically a problem.

I often tell the older shooters I teach to wear their reading glasses. Not only does the improved sight alignment help, but I think the inability to see the target clearly strongly discourages them from trying to focus on it, which helps even more.

One common technique for people who are close to or have age-induced presbyopia is to perform the surgery on only one eye, or, depending on the prescription, to apply it in different amounts. The idea is to get one eye which is good for near vision and one that is good for far vision. Sort of the same notion as bifocals, but applied directly to the eyes. Apparently the brain adjusts quickly and effectively to this and you end up feeling as though you have good vision at all ranges as long as both eyes are open.

I'm considering doing that. I'm 45 and my eyes have just begun to change. I'm still generally myopic, but so far the change just requires me to take my glasses off when doing close work. I'm going to give it a couple more years to be sure my eyes have more or less settled, then get surgery on one or both, in whatever degrees will give me the best overall visual acuity and flexibility.

If your eyes haven't actually changed yet, then it's something of a crapshoot. The idea is to adjust your vision based on guesses as to how they're going to change. That said, my optometrist says that they can make very good guesses. The only reason he's recommended that I wait is because I'm not far from the point where guessing won't be required, based on my history of general visual stability and current rate of change.

Interesting, but not surprising. It's unlikely that any new idea in cosmology (or anywhere else) is actually truly "new" by the time it garners sufficient support to warrant widespread serious consideration. The process by which knowledge is created -- conjecture and criticism -- almost precludes it. Ideas, even correct ideas, assuming this is and assuming that Greenstein actually had the same idea, not less-correct variant, nearly always come before the knowledge needed to identify them as correct, or at least as more correct than competing ideas. This is why simultaneous invention is so common, because the groundwork is thoroughly well-laid before the crucial bits fall into place that make it possible to put it on a firm foundation.

I don't disagree in general, but please remember the original context here was whether going it alone as a start-up might be a liability if Big Players declined to let you into those programmes, i.e., we are talking about precisely the situation where the platform maintainer might not have that implicit interest in your success.

The key difference IMHO is that I don't need Microsoft to care about me. I can write Windows-based software and sell it to Windows-using customers with no help from Microsoft except selling us Windows and any related tools in the first place, and all three parties win on the deal. If I want to sell an iPhone app, my entire revenue stream is entirely dependent on Apple, and Apple are not known in these parts for the care with which they examine new apps or the caution or neutrality they exhibit when banning something they decide they don't like.

I love how pretty much every country has come to the same conclusion: We can bypass our own laws if we have someone else do it for us.

There's nothing surprising in this. Most countries hire consultants and advisors from the same international legal/accounting firms, who themselves have been trained in the same schools of thought, and often the same universities. The international ascendancy is mostly a mono-culture.

No... The H1-B program is a way of making people more successful in their home country not to bring that knowledge and talent into the U.S. on a permanent basis.

As an outsider with no bias here, it occurs to me that the above is probably in the long-term interests of the US as well. India is a big place, with lots of people, many of whom today are struggling with things we take for granted in the West. Helping to improve things like education standards and technological advancement potentially develops a vast export market for US products and services in the future and/or a mutually advantageous trading partner.

People often look at international aid schemes as charity, and support them on that basis, but the truth is that there is often a level of "enlightened self-interest" behind government support for those schemes, because things like global security and having stable economies in your trading partners are in everyone's interest. Much the same arguments could be made, as I understand it, for the US H1-B programme.

Submission + - Letter to Congress: Ending U.S. Dependency on Russia for Access to Space 1

Bruce Perens writes: I've sent a letter to my district's senators and member of congress this evening, regarding how we should achieve a swifter end to U.S. dependency on the Russians for access to space. Please read my letter, below. If you like it, please join me and send something similar to your own representatives. Find them here and here. — Bruce

Dear Congressperson Lee,

The U.S. is dependent on the Russians for present and future access to space. Only Soyuz can bring astronauts to and from the Space Station. The space vehicles being built by United Launch Alliance are designed around a Russian engine. NASA's own design for a crewed rocket is in its infancy and will not be useful for a decade, if it ever flies.

Mr. Putin has become much too bold because of other nations dependence. The recent loss of Malaysia Air MH17 and all aboard is one consequence.

Ending our dependency on Russia for access to space, sooner than we previously planned, has become critical. SpaceX has announced the crewed version of their Dragon spaceship. They have had multiple successful flights and returns to Earth of the un-crewed Dragon and their Falcon 9 rocket, which are without unfortunate foreign dependencies. SpaceX is pursuing development using private funds. The U.S. should now support and accelerate that development.

SpaceX has, after only a decade of development, demonstrated many advances over existing and planned paths to space. Recently they have twice successfully brought the first stage of their Falcon 9 rocket back to the ocean surface at a speed that would allow safe landing on ground. They have demonstrated many times the safe takeoff, flight to significant altitude, ground landing and re-flight of two similar test rockets. In October they plan the touchdown of their rocket's first stage on a barge at sea, and its recovery and re-use after a full flight to space. Should their plan for a reusable first-stage, second, and crew vehicle be achieved, it could result in a reduction in the cost of access to space to perhaps 1/100 of the current "astronomical" price. This would open a new frontier to economical access in a way not witnessed by our nation since the transcontinental railroad. The U.S. should now support this effort and reap its tremendous economic rewards.

This plan is not without risk, and like all space research there will be failures, delays, and eventually lost life. However, the many successes of SpaceX argue for our increased support now, and the potential of tremendous benefit to our nation and the world.

Please write back to me.

Many Thanks

This is a murky field. A polygraph does present useful information; it's just not necessarily whether the person is telling the truth. The major decision part of any polygraph system is the operator, and they need to have sp,e training in physical psychology to be predictably any good at using the equipment.

That's nice bullshit sandwich wrapped in pseudo-science bread you've got there.

I disagree. As I stated, polygraph machines are NOT lie detectors; the fact that they've been popularized in this way is beside the point.

Polygraphs only work in the way that swinging a five dollar wrench at someone works. It convinces them to tell you what you want to know on their own because their afraid of it. That's it.

No; that's the way that polygraphs are usually used by government and law enforcement to get the answer they want. Polygraphs actually WORK by measuring your vitals and recording the information change over time. There's a huge difference there.

And pretty soon, those health bands everyone's starting to wear will be indistinguishable from polygraphs; the only real difference being application and interpretation.

The phrase "He failed/passed a polygraph" is the biggest load of shit in "law enforcement."

I disagree here too -- it is totally eclipsed by the phrases "he was obstructing justice!" and "that DNA evidence proves it."

These days, polygraphs are much more abused by government on government employees than they are on civilians by law enforcement. But the LE abuses are the worse of the two I agree, as they're performed against people who have no choice.
