  1. Re:Fermi's Paradox on Global Catastrophe, Even Human Extinction, Isn't All That Unlikely (theatlantic.com) · · Score: 1

    It might have, of course.

    If the first observation would have been one of a green square "thingy", then that would have been how the Universe would look today.

    Of course, observing a green square "thingy" is only possible if that is still possible, given all the observations that have been made up to that point - or, to word it differently, given the Universe that we created up to that point.

    Perhaps the laws of physics dictate that there must be one civilization in the universe. Not less, not more.

    Why? Because life, or consciousness, can only exist if the laws of physics are consistent.

    Let me provide an example description. In the beginning, there was human consciousness. Nothing else existed. For example, there was no Sun.

    The latter statement should be read as "Sun was not". So I'm not saying that the Sun didn't yet exist. What I'm saying is that not even the concept of "Sun" existed. "Sun" wasn't present, "Sun" wasn't absent. It didn't exist, it didn't not-exist. It just "was not". It was like "undefined".

    But then, the consciousness looked upward, and observed a yellow disc.

    From that moment on, the number of possible universes was greatly reduced. Until this disc was observed, many universes were possible: ones with a yellow disc of course, but also ones with a green square, ones without any such thing, ones with 42 dodecahedrons circling each other, and so on. But as soon as the yellow disc was observed, the number of possible universes was reduced to those were a yellow disc could exist.

    And so on for all other observations. Each new observation reduced the amount of possible universes we could be living in. One could say that human consciousness created the known universe, just by observing it.

    Now imagine that the universe contained two, or even more, consciousnesses that independently observed the universe. That's impossible! They would be independent, so they would be creating different universes. Yet they would also have to be in the same universe we are in if we were ever to observe them. These two requirements are incompatible.

    Therefore, we are alone. We must be. Because there's only one law of physics, which is the law of consistency.

  3. Open-source pharma already exists on What Is Open Source Pharma (and Why Should You Care)? · · Score: 1

    Open-source pharma already exists. It's called homeopathy. Though it's still around and amazingly popular, it does not work.

    Why should we expect open-source pharma to be different from homeopathy, or from phytotherapy at best?

  5. Small blast followed by ordinary blast on Hubble Spots Star Explosion Astronomers Can't Explain · · Score: 2

    It's quite simple. First, the star underwent a small blast, too small to be detected, in which it expelled a layer of gas. That gas formed a cloud around the star. Then, there was an ordinary blast. What we saw was the gas cloud being illuminated by the ordinary blast.

  6. Get two different lenses on Ask Slashdot: Are Progressive Glasses a Mistake For Computer Users? · · Score: 1

    Some 18 months ago, I started to have problems reading, especially in darker environments. Reading the menu in some restaurants was getting real hard.

    My ophtalmologist proposed to try two different contact lenses (I use contact lenses for many years already). One lens, for my left eye, would have optimal focus at short distances. The other lens, for my right eye, would have optimal focus for long distances.

    My ophtalmologist told me that some people love this setup while others just get nausea, so I could try them for a month. If I decided they were not for me, I could replace them with ordinary contact lenses at no cost (but then I would of course need reading glasses). If I liked them, I could keep them.

    I kept them. I love them.

    My brain automatically uses the eye that's most suited for the distance I'm focusing at. So now, reading from the computer screen, I use my left eye. If I close my left eye and use my right eye to look at the screen, things get a bit blurry.

    Similar for long distances. When driving, my brain automatically uses the right eye, so I can see traffic and traffic signs in good focus. If I close my right eye while driving, things get blurry.

    This all happens totally automatically. I do not have to spend any effort.

    Estimating speeds and distances is still possible. I have no problems catching a ball thrown toward me, and I can still estimate the locations and speeds of cars, cyclists and pedestrians while driving. It seems 3D vision still works when one image is sharp while the other one is blurry.

    I use contact lenses, but my ophtalmologist told me this setup works with (single focus) glasses too.

    I suggest you propose this setup to your ophtalmologist and see what (s)he says.

    An email address travels through several systems between you and the other side. This applies to the time when you fill in your email address in a web form, and even more so when the company sends out emails to your address.

  13. Re:A short list on Ask Slashdot: How To Clean Up My Work Computer Before I Leave? · · Score: 1

    After that, one should clean the free space on the disc. If you have no rights whatsoever, the simplest way to do that is by filling up the disc with random files until it's full. Then erase the filler files and you're done.

    I do this by creating a text file called 'a' for simplicity, 4096 bytes long, containing only the character 'Z' (which makes for a nice binary pattern). In a DOS prompt, I issue commands like

    copy /b a+a+a+a+a+a+a+a+a+a+a+a+a+a+a+a b
    copy /b b+b+b+b+b+b+b+b+b+b+b+b+b+b+b+b c
    copy /b c+c+c+c+c+c+c+c+c+c+c+c+c+c+c+c d

    Sounds nice, but...

    What if the wife gives in, you then have kids, and 6 to 18 months after birth (or whatever is the time for vaccination), she changes her mind? I've seen it happen...

    What if she changes her mind, tries to re-discuss the issue with her husband, finds she can't convince him, and only pretends to give in. She says she'll bring the child to vaccination, but in reality, she doesn't. She just lies to her husband.

    The problem is: if a mother firmly believes that this is in the best interest of her child, and if she believes vaccination poses a risk to her beloved little child, then those feelings are so overwhelming, there's nothing she can do to fight them.

  20. Why use utility poles at all? on Google Fiber Work Hung Up In Kansas City · · Score: 5, Interesting

    This question may just show that I'm from Europe... But I really wonder: why use utility poles at all? What's the reason? Here, almost all cities and towns got a fibre-optic network during the last three years. I too have a fibre connection in my home, just like the rest of my town. During all of these activities, utility poles weren't even considered. It was clear from the start that the fibres would go underground. Everywhere. So narrow (50cm or narrower - that's about 1 to 1,5 feet for non-/. readers) trenches were dug in every sidewalk. Where roads had to be crossed, a kind of horizontal drill was used. The same for going from the street to my house: a narrow hole was drilled under my front garden, leaving no visible trace of the fibre. (Actually, it may have been more "pushing" than "drilling", but that's a minor technical detail). I'm just saying - im my state of mind, going underground is just sooooo logical, that alternatives weren't even considered. Why is it so different in the USA?

    Why rent a car?

    Here (The Netherlands), we've got the so-called Train Cab. Goes like this: you buy your train ticket plus a train-cab ticket. When you get off the train, you walk to the train-cab stand and get in the cab. It's a shared cab - it will drive as soon as it's full, or as soon as the first passenger is waiting for ten minutes, whichever happens first. The driver selects the best route to deliver all passengers to their destinations.

    Alternative is the train bike. For a small fee, you rent a bike at the train station.

  22. Reason for input lag on Input Lag, Or Why Faster Isn't Always Better · · Score: 5, Interesting

    The reason for input lag is that manufacturers want the on-screen image to quickly change without ghosting. Here, quickly means "in as few ms as possible", not "without delay". So if you see a change only two seconds later, but the change is instantaneous, that's considered good.

    To achieve this, the display electronics must know what the next frames look like. So they buffer two or three frames, then adapt the overdrive on a per-pixel basis to the contents of the next few frames.

    Pro: smoother video playing
    Con: a delay of two or three frames
