Google+ salvaged collection of animations (III): online again!

UPDATE: Chemlambda collection of animations. is the version of the collection hosted on github. The original site is under very heavy traffic (in Jan 2020).

UPDATE: For example the 2 neurons interacting animation can be remaked online to look like this:

2neurons

First you use the mouse wheel to rescale, mouse to translate. Notice the gravity slider position. This is an animation screencasted from the real thing which takes 8 min to unfold. But in this way you see what is happening beyond the original animation.

Btw, what is such a neuron? It is simply a (vectorial) linear function, which is applied to itself,  written in lambda calculus. These two neurons are two linear functions, with some inputs and outputs connected.

Soon the links will be fixed (internal and external) [done] and soon after that there will be a more complete experience of the larger chemlambda universe. (and then the path is open for pure see)

In Oct 2018  I deleted the G+ chemlambda collection of animations, before G+ went offline. Now, a big part of it is online, at this link. For many of the animations you can do now live the reduction of the associated molecule.

The association between posts, animation and source mol file is from best fit.

There are limitations explained in the last post.

There are still internal links to repair and there has to be a way to integrate all in one experience, to pay my dues.

I put on imgur this photo with instructions, easy to share:

Use wheel mouse to zoom, mouse to move, gravity slider to expand.

The salvaged collection of animations (II)

UPDATE: Chemlambda collection of animations is the version of the collection hosted on github. The original site is under very heavy traffic (in Jan 2020).

UPDATE: much better now, although I seriously consider to jump directly to pure see. However is very rewarding to pass over blocks.

(Continues the first post.) I forgot how much the first awk chemlambda scripts were honed, and how much the constants of the animations produced were further picked so to illustrate in a visually interesting way a point of view. The bad part of the animations first produced is that they are big html files, sometimes taking very long to execute.

The all-in-one js solution built by ishanpm, then modified and enhanced by me, works well and fast for graphs with a no of nodes up to 1000, approximatively. The physics is fixed, there are only two controls: gravity (slider) which allows to expand/contract the graphs, and the rewrites slider, which changes the probabilities of rewrites which increase/decrease the number of nodes. Although there is randomness (initially in the ishanpm js solution there was not), it is a weak and not very physical one (considering the idea that the rewrites are caused by enzymes). It is funny that the randomness is not taken seriously, see for example the short programs of formality.

After I revived the collection of animations from G+ (I kept about 300 of them), I still had to associate the animations with the mol files used (many of them actually not in the mol library available) and to use the js chemlambda version (i.e. this one) with the associated mol files. In this way the user would have the possibility to re-done the animations.

It turns out it does not work like this. The result is almost always of much lesser quality than the animation. However, the sources of the animations (obtained from the awk scripts) are available here.  But as I told at the beginning of the post, they are hard to play (fast enough for the goldfish attention), actually this was the initial reason for producing animations, because the first demos, even chosen to be rather short, were still too long…

So this is a more of a work of art, which has to be carefully restored. I have to extract the useful info from the old simulations and embed it into a full js solution. Coming back to randomness, in the original version there are random cascades of rewrites, not random rewrites, one at a time, like in the new js version… and they extinguish the randomly available pockets of enzymes, according to some exponential laws… and so on. That is why the animations look more impressive than the actual fast solution, at least for big graphs.

It is true that the js tools from the quine graphs repository have many advantages: interaction combinators are embedded, there is a lambda calculus to chemlambda parser… With these tools I discovered that the 10 nodes quine does reproduce, that the ouroboros is mortal, that there are many small quines (in interaction combinators too), etc.

And it turns out that I forgot that many interesting mols and other stuff was left unsaid or is not publicly available. My paranoid self in action.

In conclusion probably I’ll make available some 300 commented gifs from the collection and I’ll pass to the scientific part. I’d gladly expose the art part somewhere, but there seems to be no place for this art, technically, as there is no place, technically, for the science part, as a whole, beyond just words telling stories.

There will be, I’m sure.

Morlocks and eloi in the Internet of Things

For any fan of Neal Stephenson and Cory Doctorow,  the contents of the following opinion piece on goals and applications of the Internet of Things (IoT) should be no great surprise.

I am using the post Technical Machine – Designing for Humans as a study case.

[ Technical Machine is the company which builds  the Tessel. This is a product with a great potential! I wish I could use tessels for   the purpose explained in the post Experimental alife IoT with Tessel .  ]

This nice post is interesting in itself, but it is also an example of the shifting of the ideology concerning the Internet of Things.

I extract two contradictory quotes from the post and then I discuss them (and explain why they seem to me contradictory).

(1) ” A completely interactive tool, one that seamlessly incorporates humans as a piece of the system, is a tool that people don’t even think about. That’s the end goal: Ubiquitous Computing as Mark Weiser imagined it. Every object is an embedded device, and as the user, you don’t even notice the calm flow of optimization.
The Nest thermostat is a good example of this sort of calm technology. The device sits on your wall, and you don’t spend much time interacting with it after the initial setup. It learns your habits: when you’re home, when you’re not, what temperatures you want your house to be at various points in the day. So you, as the user, don’t think about it. You just live in a world that’s better attuned to you.”

(2) “I think that one of the most interesting things we’ll see in the near future is the creation of non-screen interfaces. Interacting with technology, we rely almost solely on screens and buttons. But in the physical world, we use so many other interfaces. […] there’s a lot of fascinating work going on to receive outputs from humans. […] The implications there are amazing: you can wire up your own body as an electrical input into any electrical system– like a computer, or a robot, or whatever else you might build. You can control physical and digital things just by thinking really hard or by twitching your fingers.”

Now the discussion. Why are (1) and (2) contradictory?

I shall explain this by using the morlocks/eloi evocative oversimplification.

From historical reasons maybe the morlocks (technical nerds) are trained/encouraged/selected to hate discussions, human exchanges and interactions in general. Their dream technology is one like in (1), i.e. one which does not talk with the humans, but quietly optimize (from the morlock pov) the eloi environment.

On the contrary, the eloi love to talk, love to interact one with the others. In fact the social Net is a major misuse of morlock technology by eloi. Instead of a tool for fast and massive share of data, as the morlocks designed it, the Net became a very important (most important?) fabric of human interactions, exchanging lolcats images and sweet little nonsenses which make the basis of everyday empathic interaction with our fellow humans. And much more: the eloi prefer to use this (dangerous) tool for communicating, even if they know that the morlocks are sucking big data from them. They (the eloi) would prefer by far to not be in bayesian bubbles, but that’s life, they are using opportunistically things they don’t understand how they work, despite being told to be more careful.

The quote (2) show that people start to think about the IoT as an even more powerful tool of communication. OK, we have this nice technology which baby-sits us and we live calm lives because quietly the machine optimizes the little details without asking us. But, think that we can use the bit IoT machine for more than conversations. We can use it as the bridge which unites the virtual and the meat spaces, we can make real things  from discussions and we can discuss about real objects.

This is a much more impressive application of the IoT than the one which optimizes our daily life. It is something which would allow to make our dreams come true, literary! And collaboratively.

I have argued before about that, noticing that “thing” means both an assembly and a discussion (idea taken via Kenneth Olwig) and object is nothing but the result,  or outcome of a discussion, or evidence for a discussion. See the more at the post Notes for Internet of Things not Internet of objects.

It’s called “Internet of Things” and not “Internet of Objects” and it seems that morlocks start to realize this.
