Comment Paper with holes has advantages (Score 2) 375

Paper tapes and classic yellow tty paper printouts from
the early 1970s, probably no timestamps though. PDP 8 FOCAL

Punch cards and printouts from mid 1970s, printouts would
have timestamps. CDC 6500, mostly FORTRAN, COMPASS (yeech)
Also some graphics printouts, one of which was published.

DEC tape from a famous PDP 11/70 running PWB Unix,
written 1979. Wish I had a DEC tape drive.

If I were sufficiently motivated I could
presumably look up the formats for paper tape
and punch cards and get the info. So of course
it is the DEC tape I'd like to be able to read.

I wear glasses virtually all day every day.

Here is an example that is constant: Vision in the eye that had the retina
surgically reattached still looks distorted (like looking through textured
privacy glass) after a year. Theory is that the retina didn't get reattached
smoothly.

The upside-down lens experiment sounds interesting. Maybe my brain just
isn't plastic enough.

> Sure it might not be ideal but it's better than not being able to see at all.

I'm not saying it wouldn't be an improvement, I'm just doubting that it would
look normal.

I sincerely doubt that. I can't even get used to the "wide angle lens"
effect of my eyeglasses. (Changing the focus to correct for myopia
changes the magnification.) I would *really* like lenses that correct
the focus without changing the magnification.

This "donut" thing sounds worse.

Comment Optics question (Score 1) 146

For the optical wizards out there, what would it take to make
eyeglasses that can correct extreme myopia without changing
the magnification? Would a multiple element lens be able to
do this?

Adjustable power lenses for $19 ? What's the catch?
More distortion or other optical problem? Are they fragile
or otherwise not very durable? These sound wonderful as
an alternative to bifocals/trifocals/etc. Need to look
at something X distance away? Just adjust your glasses
as needed.

Why aren't drugstore reading glasses classified as "medical devices"?
If you are slightly far-sighted you can get 3 pairs for $10 and
the quality is surprising decent. If you are near-sighted you
have to spend hundreds of dollars.

The eyephone app thingy sounds useful, (was planning on actually
reading TFA ( *gasp* ), but it crashed my browser) but will it
check your eyes for health problems? Of course none of my eye
doctors ever warned me that I was at high risk for retinal
detachment, so maybe the eyephone app would have been just as good?

Comment Two questions (Score 2, Informative) 54

Is anyone working on treatments (stem cells, carbon nanotubes,
magic fairy dust, whatever...) for repairing a wrinkled retina?
(It detached, and the fine surgeon didn't get it reattached smoothly,
so that eye is like trying to look through textured privacy glass.)

For the optical wizards out there, what would it take to make
eyeglasses that can correct extreme myopia without changing
the magnification? Would a multiple element lens be able to
do this?

For those of you with extreme myopia, you are at higher risk for
retinal detachment. Talk with your eye doctor about getting
your retina "spot welded" with a laser to prevent this.
You do NOT want your retina to detach!!!

Comment antitrust (Score 2) 160

NBC is a free broadcast network. Comcrap is pay cable.
How well is comcrap going to support/maintain NBC's broadcasting
given that comcrap wants everyone to subscribe to their crappy
cable service?

OTA TV is less compressed than cable/satelite,
and recording it is legal. MIfiAA lawyers can take
a hike.

Yeah, NBC doesn't have much worth watching at the moment,
but that stuff goes in cycles, and someday NBC will have
great stuff again. Unless comcrap is allowed to destroy
NBC forever.

Clear antitrust, but is anyone paying attention? Where
is Teddy Roosevelt when you need him?

And now for something completely different:

> You couldn't get 90% of voters to oppose Hitler.

Dig out your history books and look up who was running
against Hitler. Reminds me of some recent US elections.

Reiser has a method for eliminating unwanted bits, but there

Which means idiots will assume that it never happens. In other

Such a limited view. I have lots of random access files I

Comment Calm down, the glass works great! (Score 4, Informative) 762

My VW has special glass that prevents the interior from
heating up and it works *great*. Park the thing on blacktop
all day in the hot summer sun and the interior barely gets
warm at all. Orders of magnitude more comfortable than cars
with regular glass. I assume the glass is low-e although VW
didn't describe it as such.

The glass is no darker than normal factory tinted glass.
The garage door opener remote works fine.

For those of you whining about the heavy hand of government,
there are many far worse problems than requiring decent
glass in cars. Many of these problems are discussed in
slashdot so you ought to be aware of them.

Maybe yours doesn't but mine does.

Comment Acetylcarnosine as alternative to cataract surgery (Score 1) 220

As mcgrew points out, the treatment for retinal detachment is such fun.
Surprisingly, having your eyes spot-welded with a laser is the least of it.
The scleral buckling makes your myopia even worse. (Why can't you get
inexpensive glasses with minus lenses similar to the drugstore reading
glasses?) Trying to sleep face down to keep the C3F8 Octafluoropropane in
the correct place is a nightmare. And then, the C3F8 gives you cataracts.

Has anyone tried http://en.wikipedia.org/wiki/Acetyl-carnosine
eyedrops as an alternative to surgery for cataracts? So far I
haven't found any reference to risks, side effects or other
downsides, which seems too good to be true.
