I had it done in Japan, and instead of giving you Valium they have a young female nurse hold your hands :)

The actual procedure was interesting, but I was nervous about accidentally moving my eye to look at the interesting pattern of flashes (although I know it compensates for movement).

My vision was amaaazing for about a week, but then I started to get really dry eyes.
Now 3 years later my vision is apparently good in focus, but it is usually blurry because my eyes are so dry.
Drops only help for about 5sec.

So it is nice to be able to work etc without glasses/contacts, but at night my vision is terribly blurry unless I can keep my eyes moist.

Make sure you don't have any possible issue with dry eyes before you consider LASIK!

It's not just mathematicians working for the NSA who are at fault; at this point, anyone working there is knowingly helping evil prevail. Anyone who doesn't quit is a scumbag.

If there was no risk of becoming homeless and starving, people would have a lot more choice in the matter...

Of course the problem with placebos is that they essentially require lying to the patient. If you are honest and actually tell the patient "it's just a sugar pill" then it's not going to have any affect.

You would think that, but actually there was a study where the patents were TOLD that it was a placebo (and explained what a placebo is) and it still worked (!). I saw it in a documentary on youtube a week or so ago but can't find it now.

Basically, brains are wierd.

I can't comprehend how someone could not enjoy ANY music, music is the fundamental pre-cursor to language, not only is it deeply ingrained into humans but species as diverse as whales and grasshoppers use music to communicate with each other.

Interesting to know that 1-3% are like me.
I will clarify this for you.

I have zero interest in music. I have never bought (or pirated) a CD or mp3 in my life.
Why people are so obsessed with music I can't understand at all.
It's like how some people looove stamp collecting, I don't understand that obsession either.

It's not a DISlike of music, it's just no interest.
Sure some music has a good beat, or a catchy tune, and I won't complain if someone plays music, but I would never actually choose to play music myself.

Besides this I am pretty much the same as everyone else, I'm not autistic or anything.
I'm an engineer, with friends and a girlfriend, hobbies and a good job.
Music just isn't any more interesting to me than bird noises etc.

+ - Nvidia G-Sync Technology Preview: Quite Literally A Game Changer->

Submitted by brittlendor
brittlendor (2623305) writes "If you’re a PC gamer, you're forever faced with this dilemma: Disable V-sync and live with tearing, or turn it on and tolerate annoying stutter? Nvidia promises to make that question obsolete with a variable refresh rate technology it calls "G-Sync". First announced two months ago, the company finally revealed details on Wednesday. In a nutshell, G-Sync allows your monitor and graphics card to run at the same refresh rate, therefore negating both tearing and stuttering. Nvidia aims to integrate G-Sync boards into PC monitors starting in Q1 2014.

Of course, in order to take advantage of G-Sync, you’ll not only need a new monitor that features the technology, but also an Nvidia graphics card, specifically the GeForce GTX 650 Ti Boost and up. Asus is set to ship a 144Hz 1080p model early next year, and Nvidia is already prepared to take G-Sync to 4K. Unfortunately, it doesn’t appear likely that G-Sync will become an industry standard. Nevertheless, the V-sync conundrum has haunted PC gamers for over a decade, so in the ongoing Nvidia versus AMD graphics battle, G-Sync could prove to be a real game changer."

Philip Ross (3389483) writes "Astronomers have warned that our planet is long overdue for a defense plan against catastrophic asteroid collisions. When it comes to deflecting Earth-obliterating celestial bodies, short of a superhero capable of punching the approaching rock back into outer space, there is no single force dedicated to stopping cosmic bullies from striking our little blue planet straight in the eye. That’s why the United Nations said it will establish an International Asteroid Warning Group to intercept and divert dangerous asteroids."

Lucas123 (935744) writes "Avi Reichentall, CEO of 3D Systems, one of the largest consumer 3D printer companies, has already been able to configure his machines to create a variety of confections. Now he says it won't be long before a chocolate printer can rest beside your coffee maker on the kitchen counter. "I want it to be as cool as a Keurig coffee maker," Reichentall told a crowd at the Inside 3D Printing Conference this week in San Jose. "We're going to bring to pastry chefs and confectionaries and bakers a whole range of new sugar printing capabilities. Meanwhile, Pablos Holman, an inventor at Intellectual Ventures Laboratory, said he and other researchers are working to create printers with toner-type cartridges that hold pulverized freeze dried foods. When dispensed, water and heat is added to cook the food and meals are printed one micro-layer at a time. Not only would the printers be able to prepare foods on the spot, but they could add minuscule amounts of various nutrients to foods to make them healthier without effecting taste. Beyond convenience, 3D printable foods would also avoid enormous waste both at grocery stores where tons of spoiled food is tossed regularly, but in households were up to 60% of food is wasted."

I use the stairs when going up to my office in the morning and at lunch.
If there are people there, I do my usual 2 steps at a time, fast pace but not enough to make people look at me funny.
If there's nobody around, I run up as fast as possible, then recover for a min at the top.

At first I couldn't make it all the way running, but I can get up the 6 floors in ~24 seconds now and can breathe normally enough after that people in the office don't notice. It's not that much, but better than nothing.

The process is absolutely fascinating and follows the steps of Viking blacksmiths from a thousand years ago. It starts by taking small bars of metal that get heated and hammered together until they become a solid piece. He then shows how to form it with the hammer, heat treat and polish it. All the videos are narrated explaining the purpose of each step. Sure beats sitting in front of the computer."

It has been shown many times in studies that people are able to read a lot of emotion by looking at another person's eyes.

This is also the main reason most manga and anime authors prefer to draw big eyes. They're a much easier way to transmit emotions than body postures, allowing for a faster drawing process...

That reminds me of something interesting I noticed - in "western" countries the emoticons are focussed on the mouth, :) :( :p etc
But in Japan, they are mainly about the eyes, like ^_^ (others mangled by slashdot)

+ - Ask Slashdot: The Search for the Ultimate Engineer's Pen-> 1

Submitted by Laser Dan
Laser Dan (707106) writes "I'm an engineer (robotics) who can't seem to find a pen that satisfies me.
Most of my writing is just temporary "thinking notes" on random bits of paper, like diagrams, flowcharts, equations etc, but pens always seem to have one or more of the following issues:
1. They write too thickly — I write very small, and when I start adding extra details to diagrams it gets even smaller. A line width of about 0.2-0.4mm would be good.
2. The ink bleeds, making the lines thick and unclear.
3. The ink is slow to dry or the tip grows blobs of ink, causing smudges everywhere.
4. The first line drawn is not fully dark, as the ink takes a short distance to get going.
5. The lines drawn are faint unless you press hard (I don't)

I have been given several fancy pens (Parker etc) over the years but they all suffered from problems 1, 3 (blobs), 4 and 5.
I'm considering trying a Fisher space pen, but it looks like even the fine cartridge writes rather thickly.

Have any fellow Slashdotters found their ultimate pen?"

What a ridiculously disproportionate penalty, I thought only the US was that screwed up.
I blame Sony.

I'm living in Japan, so lately I have been renting a "seedbox" in the Netherlands for $15/month.
I can download whatever I want to through the web interface, then copy it via sftp.
I'm sure solutions like this will start becoming a lot more common soon.
