Well, "social science", at least.

Well, "social science", at least. The thing is, most of these are questions from Western culture, and really they may either be the "wrong" questions, or culturally loaded. It might not matter in the end if there is an after life or not, provided you make an effort in this one.

Also of course, if say we all live in an "ancestor simulation", then things like numbers and afterlife's might just be part of the substrate, the program running it. It may not matter what the answers are also, because the important this is actually the questioning.

Urk!

Urk! I got a mysterious "error 1" message when trying to run Photoshop CS6 (and later Illustrator as well) this morning. I followed the procedure to fix this but nothing worked, so I'm reinstalling both versions again today. Annoying. I just want to use it to redo a comic of mine from  2000. :(

An inside look at the Google Brain team

For the past few months, we've had NY Times Magazine reporter Gideon Lewis-Kraus visit the Google Brain team several times and hang out with us for a few days at a time, with an eye towards writing an article about how our research team operates and what we're working on. We gave him pretty open access to our building, the people in the team, many of our meetings, etc., and over the course of several visits, he decided to focus his story on the origins of the Brain team, and on our in-progress collaboration with the Google Translate team to replace the old phrase-based translation system with a neural machine translation system (essentially part of the article is a behind-the-scenes look at how the scientific work in https://arxiv.org/abs/1609.08144 and https://arxiv.org/abs/1611.04558 came about).

This long article is the result of his visits and synthesis of what he learned. Gideon, I think the article turned out really well!

I moved the server to my RecRoom PC. As it's all based on N and J network drives, it was a smooth transition. Now to find my external backup drives and see what space I have left. 

Extra thought:
It occurred to me that when I get some extra $$$, I could get a dedicated server box built, one that was ultra reliable, and with very FAST storage. That would be the place to put a hypergrid-connected grid.

Well, my Lounge Room PC stopped working, and that was that!

Well, my Lounge Room PC stopped working, and that was that! I think it's the power supply. It spontaneously rebooted twice in the last two months, and on one occasion gave an error message about the power supply. I was going top wait until I got back from New Zealand to replace that - which I still might do. Trouble is that the Lounge Room PC is also my home network server. Oops!

UPDATE:
I flicked switch at the back OFF and then ONE, and pressed the "On button" on the front again, and it booted! However, that switch is part of the power supply, so I think my diagnosis is still correct. Time to backup while I can, and move the stuff on the server to another PC.

If this is practical and affordable I can see plenty of applications in Australia!

Triple Pendulum Control

A few years ago Dr. Tobias Glück from Technische Universität Wien, found that along with his mathematical insights, computers and numerical methods were now fast enough to swing-up and balance a pendulum, on a pendulum, on pendulum on a sliding rail under computer control.

IEEE CSS Video Clip Contest 2014 Submission

Triple Pendulum on a Cart (YT ~1 min.): https://goo.gl/XkKxHL


The presented work deals with the swing-up of the triple pendulum on a cart. The swing-up maneuver is accomplished within a two-degrees-of-freedom control scheme consisting of a nonlinear feedforward controller and an optimal feedback controller. Based on a precise mathematical model, the feedforward controller was obtained by solving a nonlinear two-point boundary value problem with free parameters. A time-variant Riccati Controller was developed in order to stabilize the system along the nominal trajectory and an Extended Kalman Filter was used to estimate the non-measurable states. The overall control strategy for the swing-up maneuver was successfully implemented and tested on an experimental test bench. Up to the authors’ knowledge, this is the first contribution so far providing numerical and experimental results of the swing-up maneuver for a triple pendulum on a cart.

This is an old article.

This is an old article. I should imagine that the same analysis could be used on any MMO as well. I have also (some years back) come across an online calculator that would calculate what a second life avatar's carbon footprint was. However, it seemed to "double count" the cost for the linden servers and  on home computers, and I suspect that's an error, because it fails to account for the other uses of the home computer.

Looks like Open Canvas is getting an update, which includes adding GIF animation capability. I can't help thinking that this is in response to Clip Studio Paint getting animation capability. I used OC for a while a few years back, but committed to Manga Studio for various reasons. Open Canvas is very popular with anime/manga fans and has a replay function where you can see how an image was drawn.

A few weeks ago, I posted (goo.gl/mE052w) about one of the stranger legacies of the Cold War – a never-launched (for obvious reasons) American plan involving an Atomic Zeppelin fleet, which would patrol over the world's oceans 24/7, carrying Minuteman ICBM's on board.

Now, this plan was raised as part of a fairly transparent ploy by various groups at the Department of Defense to claim that they had "thought through all options" and could therefore justify the M-X Missile program.

So I have no idea what the excuse is behind this thing, a description of a plan for nuclear-powered Zeppelins to be fielded by the Soviet Union. I'm suspecting that this appeared in Tekhnika Molodezhi for much the same reason that bizarre designs show up in Popular Mechanics: that is, as an "imagine this neat future!" gimmick rather than serious engineering.

But I'm oddly pleased to discover that both sides of the Cold War had people that looked at nuclear reactions, looked at Zeppelins, and immediately thought these are two great tastes that taste great together.

This really strange bit of lore brought to you by @PulpLibrarian over on Twitter.

"People who appreciate the beauty of mathematics activate the same part of their brain when they look at aesthetically pleasing formula as others do when appreciating art or music, suggesting that there is a neurobiological basis to beauty.

Beautiful formula
There are many different sources of beauty - a beautiful face, a picturesque landscape, a great symphony are all examples of beauty derived from sensory experiences. But there are other, highly intellectual sources of beauty. Mathematicians often describe mathematical formulae in emotive terms and the experience of mathematical beauty has often been compared by them to the experience of beauty derived from the greatest art.

In a new paper published in the open-access journal Frontiers in Human Neuroscience, researchers used functional magnetic resonance imaging (fMRI) to image the brain activity of 15 mathematicians when they viewed mathematical formulae that they had previously rated as beautiful, neutral or ugly.

The results showed that the experience of mathematical beauty correlates with activity in the same part of the emotional brain – namely the medial orbito-frontal cortex – as the experience of beauty derived from art or music.

Activity in the brain is strongly related to how intense people declare their experience of beauty to be – even in this example where the source of beauty is extremely abstract.
