solipsist··on Conway's Game of Life Extrusion
Perfect explanation. I'm pretty sure that macro is the way to go. I have a theory that you can take anything and separate it into macro and micro levels (whether it be economics, science, etc.) You can look at systems at different scales and, while there is sometimes an intermediate, it's usually possible to separate the interpretations into two distinct categories.

As mkrecny stated, choosing to observe and predict the micro aspects of our universe is a lost cause. However, finding patterns in higher levels of systems is what makes science works. While micro systems are usually the areas left for theorists, macro systems have real life applications for scientists. We predict things every day and some things are simply easier to predict than others.

solipsist··on Conway's Game of Life Extrusion
Cellular automata, which includes Conway's Game of Life, is impressive because of the complexity that arises from simplicity. Starting from just a few simple rules and starting arrangements, structures can appear that you would never have expected.

Some people believe that our universe could be a type of cellular automata itself.

There are some interesting connections between our universe and the type of cellular automata like Conway's Game of Life. It is possible to predict events in the future by looking at the big picture. Various levels and hierarchies of structures are formed in Conway's Game of Life (e.g. gliders and glider guns) that seem to obey their own rules. However, these macro rules are nowhere close to the original micro rules of the simulation. While we can look at these macro rules to make certain predictions, the only way we can determine every cell's state in the future is by letting the simulation play out one generation at a time.

solipsist··on Ask HN: Does anyone else misread the 'time since comment' as karma now?
Yes, you're not alone. This is one of those short term effects (i.e. withdrawal), although I agree that it has been annoying.
solipsist··on In regards to the opinions about the quality of HN
I think that all the meta discussions on here about the quality of HN have become a big part of what HN is. HN is a place for hackers to discuss anything that interests them; so of course that's going to include the discussion about their own community and how to make it better.

I think you're right that we have to accept the change in communities' interests over time, but don't forget that one of these interests hackers have is to improve their own community.

solipsist··on Notice: Experimenting with HN
I think the concept of seeing your own karma total goes hand in hand with seeing karma scores on your own comments. People will want to track and monitor their karma if they are able to.
solipsist··on Notice: Experimenting with HN
How about removing the total number of karma points from user's profiles now?

Excluding our own profiles, what are the advantages of seeing other's karma?

If we're going to remove the presence of karma from comments, why not with the user profiles as well?

solipsist··on Notice: Experimenting with HN
There are two types of articles that belong here on HN. The first type includes articles that speak for themselves. Everyone learns from them, but fell little need to comment unless they have something small to chime in. This type should have a low ratio of comments to upvotes.

However, the other type includes articles that provoke people and cause discussion. It doesn't just include contributing comments, but rather it contains debates and opposing opinions. These types of articles need a balance between a low and high ratio. However, the religious arguments you speak of are usually easy to find. These arguments are usually found in a deeply nested comment thread. Once you discard of fourth level comments and all the noise below, you should find that the ratio of comments is a pretty good signifier of the quality of the article.

It seems that killing two birds with one stone has worked well for the founder in the past. ReCAPTCHA does it itself, so it will be interesting to follow this project and see where it ends up.
solipsist··on Ask HN: Didn't get in YC S11? Are you going to charge forwards anyway?
If it makes you feel better, you can assume the title to be this instead:

  Didn't get in YC S11? How are you going to charge forwards?
I think the point of this post was for it to be a morale booster. While everyone might agree to go on charging forwards, people will most likely have different approaches in doing so. That's what this is all about.
solipsist··on Ask HN: How to stave off decline of HN?
The problem lies within the deeply nested threads that continuously go back and forth between a few select people. Most of the mean/dumb comments on the first level thread are downvoted or flagged and moved to the bottom. This makes it easy to read the high quality comments - just look at the top.

The problem occurs when you start reading into a nested thread of comments. Users will sometimes argue 4 or 5 times back and forth, often becoming mean and uncivil. What results is a somewhat personal discussion among a few people that doesn't fit in with the rest of the thread. While the quality may actually increase the deeper you go into a thread, the relevancy to the original thread decreases (which matters most).

I think that this behavior is what is hurting HN's overall quality. Uncivil and deeply nested threads like these are hard to keep track of and deeply get out of control.

The solution:

  - hide deeply nested threads (greater than 3 or 4 comments deep) and
    let the users choose to show them

  - promote commenting in higher threads (this will come as a result 
    of hiding deeply nested threads) 

  - hide or lessen the visibility of threads consisting of comments
    from only 2 or 3 people
solipsist··on Withdrawing from Hacker News
I understand why they were downvoted, but people responded to their message and my comment has a similar message. It looked as if people would be reluctant to consider to my arguments, but I'm pleasantly surprised that they did.

This just goes to show the value of putting in time and quality into a comment (unlike the ones at the bottom of this main thread).

You make a good point that it benefits a lot of people to know where the high profile members went, but maybe there's a better way to do it.

If there is some unique perspective on HN that can apply to everybody then, sure, go ahead and post it to HN as a blog post. However, any generic I'm-leaving-HN messages could maybe go into a category of "Leaving HN: ..." posts (instead of a link). These could still hit the front page, but there would be a clear distinction between this community news and other news.

solipsist··on Withdrawing from Hacker News
I will be probably downvoted for saying this (as I see other people who tried to convey a similar message on this thread were), but I think that posts like these are of little interest to many of us. I don't mean to offend anyone, especially not RiderOfGiraffes who I greatly admire, but I think it's worth pointing out what other HN users have been trying to say.

Posts like these are bad for HN for a few reasons:

  - they appear often and usually repeat the same message
  - they support the minority of elitists who already dominate HN
  - their content is only news-worthy to users who've been on HN
    for a while and not the new ones 
Basically, any content that is submitted to HN and refers to a user or a user's experience of HN is simply a popularity contest. Whether it becomes popular on HN depends on the popularity of the user. The active and prominent users then feel the need to upvote and comment as they can relate to the poster. However, any budding new user that is trying to 'break in' to the community is confronted with what appears to be a form of exclusivity.

What results is a thread in which the OP, upvoters, and commenters that are supporting news that only apply to them.

HN shouldn't have threads like these - threads should apply to as many people as they can. I'm not saying that life has to be fair, but I think the end of these posts would help make HN feel like a more inclusive place.

solipsist··on Poll: Do you think that the mind is physical or not?
Irony at its greatest
solipsist··on Poll: Do you think that the mind is physical or not?
Functionalism is very similar to physicalism. An interesting corollary to functionalism is that mental states are "said to be realized on multiple levels." In other words, computers and other systems could have the same sense sense of identity as humans.

From Wikipedia's article on Functionalism:

"Since mental states are identified by a functional role, they are said to be realized on multiple levels; in other words, they are able to be manifested in various systems, even perhaps computers, so long as the system performs the appropriate functions. While computers are physical devices with electronic substrate that perform computations on inputs to give outputs, so brains are physical devices with neural substrate that perform computations on inputs which produce behaviors."

Just something interesting to think about...

solipsist··on Poll: Do you think that the mind is physical or not?
I think that comprehending the non-physical part is just as hard as comprehending the communication gateway. In other words, if you can comprehend one, you can probably comprehend the other.

solipsist··on Accidental SEO: How I got 400,000 page views without even knowing it
Like others have posted, I have also had a surprising number of page views without knowing it. The secret for me was Google Images. Got an iPhone image from Apple's PR site and uploaded it to my homepage. Now my page shows up in image search on Google, Yahoo, and Bing.

Once I realized what was happening, I added some code to my webpage so that removes itself from the frame it's embedded in. It's essential the same as finding it on a web search, but it's page rank is a lot higher on the image search due to the iPhone image.

solipsist··on Angry Bird’s “overnight success” only took 8 years.
That's a gutsy thing to say. Not everyone has the potential like you and me, both who were born in the US. Not everyone can use their best learning, changing, adapting, and adjusting to get out of the place they were born into. Not everyone who tries can be wealthy in ten years.

solipsist··on Readable Hacker News Chrome Extension
I love it!
solipsist··on Khan of Khan Academy at TED (video)
Yeah, the data from the students' interaction with the video could be sent back to the teachers and end up creating a comprehensive profile of each of the student's understanding on that particular topic. Then, in the classroom, the teacher would be able to walk from student to student (or form groups of students with similar strengths/weaknesses) and provide the help they needed based on their profiles. This help would be the help that relies on direct interaction between the teacher and student.
