Journal Journal: Halting problem disproves deterministic universe?

If the universe were deterministic, then it must be possible to, given sufficient data about the universe and its current state, predict what the state of it will be at some point in the future. We shall confine our predictions for this purpose only to the outcome of a single experiment, and let us take a black box that can tell us what the outcome of the experiment will be. If such a black box cannot exist for any reason, then it follows that there are at least some factors in the universe that are non-deterministic.

The experiment is designed as follows: One first designs a deterministic system that outputs the opposite of its input. For example, let us say there are two switches labelled A and B, and if A is pressed then it outputs B and if B is pressed it outputs A. There is no reason that such a system could not be built. One then arranges for the input of this system to be the output of the aforementioned black box, which if it were possible for the black box to exist then there is no reason why this could not be done.

However, one quickly realizes in this experiment that a contradiction occurs, anything that the black box can possibly predict about the outcome of the experiment is wrong, and so either the black box cannot exist or else it is impossible for the black box to communicate to the outside world such information about the future state, which suggests that the universe is either non-deterministic, or else it may be treated as non-deterministic for *all* experimental purposes.

Journal Journal: Trump's Attack Lines On This Are Spot On 12

Trump's attack lines on this are spot on:

Donald J. Trump @realDonaldTrump - 7:01pm  12 Jul 2016

        Bernie Sanders endorsing Crooked Hillary Clinton is like Occupy Wall Street endorsing Goldman Sachs.

and

Donald J. Trump @realDonaldTrump - 7:03pm  12 Jul 2016

        Bernie sanders has abandoned his supporters by endorsing pro-war pro-TPP pro-Wall Street Crooked Hillary Clinton.

Those are valid statements. I find it hard to to argue with these.

Journal Journal: Ryan Ryttie / kesuki - Rest in peace 2

As most activity has gone away here, I often don't remember what real username maps to what person. It's fine, that is how this social media thing evolved.

What I do know, is that I knew Ryan Ryttie, from slashdot. Today, I saw a post from his sister that he passed away (Link to Facebook is public). No, I do not know the circumstances.

I know he stopped using his original username here. Ryan was a friend, sure he had is daemons. but he was a friendly and authentic person.

I post this in a journal, for others that may still wander here and may have known him.

May Ryan rest in peace.

[Edit: Ryan was known as kesuki on slashdot]

Journal Journal: One year since XP OEL. 6

Do you realize that XP was EOLed exactly one year ago?
I know many XP machines still chugging around peacefully without problems: No XPcalypse happened. This entirely fits my predictions.

XP was a (had become) a mature operating system. I abhor the fetish of "newer is better" that reigns in our industry.
