I'm told that the F35 is the largest, heaviest fighter with an airframe that produces the most drag, that the US has ever produced...

And where did you hear it? According to wikipedia:

Wingspan:
F35: 35'
F14: 64' / 38' (swept)
F15: 42'
F16: 32'
F18 C/D: 40'

Empty Weight
F35: 29,000 lb
F14: 43,700 lb
F15: 28,000 lb
F16: 18,900 lb
F18: 23,000 lb

Combat radius (internal stores)
F35: 600 nm
F14: 500 nm
F15: 1000 nm
F16: 340 nm
F18: 400 nm

Of what can be verified, none of what you heard is correct...

What will be the effects when I'm in my 80s?

Your distance vision will be clearer. You may need stronger reading glasses though.

What happens after the 3rd or 4th redo?

I highly doubt that most doctors will perform a 3rd or 4th operation on a patient. The procedure involves removing material. Obviously, there is only so much you can remove before the integrity of the eye is put at risk. That's one of the reasons I didn't get it a second time. I was a perfect candidate initially, but by the time that I needed adjustments came I considered the risks unacceptably high and went back to glasses and contacts. It was really great during the years when I could wake up with perfect vision though, I wish I would have waited the first time until my eyes really stopped changing.

I actually fainted during the initial exam, prior to surgery. My doctor was using a little yellow tool to poke my eye, and every time he poked it my vision went blurry and a machine went "BING!" I don't know why, maybe I was just holding my breath, but I went right out. Woke up to my doctor laughing.

The surgery itself was no problem, I was more interested than nervous. I could see the laser getting closer and shooting a purple beam. They sucked my eye out and I could see the vision slowly fade to black as the blood drained, and then watch it return then they were done. It was an interesting experience, I wasn't scared at all by it.

That little yellow thing though, that thing got me. Another in the list of amusing times when I've fainted.

That's what happened to me. I got the surgery when I was around 23 or 24, and yeah I had 20/15 vision for at least a year, but my eyes kept changing. After about 7 years I went back for glasses and to talk about doing the surgery again. I was advised that 7 years between surgeries is risky, because the original cut portion would have healed and they would need to cut it back again. Additionally, the possibility of complications had risen, I had something like a 20% chance of things going wrong like my lens collapsing from being too thin after 2 surgeries, things that would be fairly serious for my vision. 20% is a fairly low chance, but I considered it unacceptably high when dealing with my vision. My doctor also said that, as my eyes are now, I won't need reading glasses when I'm older. I opted to just get contacts and glasses again. I went back for contacts again recently and my eyes had only barely changed from the previous prescription. If I had waited until around 32 or 34 to get it done the first time then it probably would have stuck around a lot longer. It was really great while it lasted though.

Yeah, the first thing I thought of was: how many people who graduate with any 4-year degree stay in their field of study? Without having anything to compare this to, how do we know that the numbers for STEM graduates are abnormal?

But everybody knows that people with degrees in Communications and Political Science aren't going to work in those fields (if they even exist). But to get a job that requires "a degree" (of any type), going through an EE or physics program is hardly the most efficient route.

I've long said that the computing field is one where you can make decent money without a degree.

That also used to be more true of the economy as a whole, but I think that would be a super-risky plan for a young person starting out today. An ever-higher percentage of applicants have a degree, raising the bar.

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

Submitted by Bruce Perens
Bruce Perens (3872) 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

Bruce Perens"

Unifying the UI is less important and desirable than unifying the underlying OS. I can understand having to re-write a more restricted UI for small displays - but the core of the application? In a different language even? That should not be necessary. Granted it was justified in the past, but mobile devices are powerful enough to run a real operating system now.
