Somehow I have an impression that I tried something and could not repeat it in SML/NJ. I can recall it was about streams and lazy evaluations, but now I think that I just misused Lazy lib since I haven't used SML for a while. So this is getting easier, great, thanks! :)

Few years ago I took a course by prof. Dan Grossman on Coursera, there was a part about SML and I so liked it (the language and the course). Now I want to read Okasaki's "Purely Functional Data Structures" book and try to reproduce the code examples in SML.

How is it going? FOr advent 2018 I use scheme but after 4 stars I think that kdb+/q actually quite suitable for such kind of tasks (at least so far). I'm not very good at it but now I'm thinking about trying to redo the exercises in it.

I consider freelance as a side project (miserable, I know) and I'm able to devote ~15 hours per week to it. Plus I take several hours for English, coursera and functional programming exercises.

My next goal is to leave my job (it takes 11 hours per day including commute and lunch time) - it will free ~2.5 hours a day! So actually freelance is a side project which should help me to say goodbye to my full-time job.

So we have several facts:

- your attention can change an particle's experiment outcome (you choose future)

- we see quantum effects on tiny particles only

- perhaps gravity makes quantum effects for "heavy" objects impossible

Which leads to an idea that actually all objects have quantum effects but someone watches for all objects in the universe and makes choices (chooses future) ahead of us. And apparently we can feel his attention as gravity. But his wathcing power is restriced and he/she/it can't watch every particle in the world.

So to see the quantum world and to say hello to the god we should overload his attention with DDOS attack (perhaps Babylon tower experiment was about this).

I understand your point of view. Of course I simplifed his reasons too much. But still, I have strong impression that he was too 'romantic' and passionate to be a winner who would remain in the history of mankind as one of the greatests rulers. His war in Russia was unbelievably daring plan, for example. Did he just want to be equal to Batu khan and others who had taken Moscow too? I would not be surprized at all. Again, it is just my personal impression, it can be far from reality of course.

I completely agree it is ok to hear strange jokes and not to be offensive. But to hear 'if you can not handle a Monty Python reference maybe you shouldn't contribute' is too much for me.

[dead] 8 years ago

Can you imagine that there are people who did not watch Monty Python at all? I know it is not always easy for a western person to accept a fact that there are different cultures around the world.

As far as I understand, 'project_commits' and 'commits' have one-by-one relationship (project_commits.commit_id = commits.id). From my point of view it is a strange design since they could just add 'project_id' column into 'commits' table. 'project_commits' table seems to be redundant here.

I'd write this query:

    select pc.project_id, date_format(c.created_at, '%x%v1'), count(*)
    from commits c
        join project_commits pc 
            on c.id = pc.commit_id
    group by pc.project_id, date_format(c.created_at, '%x%v1')
And I'd use left join only at the stage when it is needed to join 'projects' dictionary with the result of the query.

Superpositions do not collapse by being observed by a human, they collapse by interacting with the rest of the world.

But the article says: "Measuring which slit such a particle goes through will invariably indicate it only goes through one—but then the wavelike interference (the “quantumness,” if you will) vanishes. The very act of measurement seems to “collapse” the superposition." "Aharonov’s approach is called the two-state-vector formalism (TSVF) of quantum mechanics, and postulates quantum events are in some sense determined by quantum states not just in the past—but also in the future. "

Doesn't it mean that future measurement 'pushes' superposition into a definite state in the past?

Does it mean we can create some machine (let's call it timegraph):

- before some sport event (NBA finals 7th match) we write a question 'who will win, A (1st team name) or B (2nd team name)?'

- do 2 experiments with photon and slits:

* (A)

* (B)

- do not measure their results until tomorrow

- tomorrow (after the match is over) you measure result of the experiment of the team that won and destroy results of the another experiment

- (returning to the previous day): look which experiment shows inteference and which doesn't
