Today, it's all about impressing each other. And that's part of social media, you know, trying to impress other people to say things that look smart, that look very intelligent, that completely align with what everyone else is saying so that they will like you, that you would have more likes on Twitter. Okay. So that's the motivation, so that you can get more awards, more grants so that you can get a tenure appointment and everyone would respect you.

And the winner is...
Finally I know why I'm so smart :D. Would like to meet Dr. Messerli (verry Swiss name, by the way) and have some dark Lindt chocolate together!
I wanted to post this one, as plant-inspired robotic design and algorithms are a new kid on the block, and then noticed that some ACT-members may already be aware of this special issue...

I love the linked article provided by Johannes! It expresses very elegantly why I still fail to understand even extremely smart and busy people in my view apparently waiting their time in playing computer games - but I recognise that there is something in games that we apparently need / gives us something we cherish ....
"In fact, half a million players so far have registered to help destroy the 64 billion tiny blocks that compose that one gigantic cube, all working in tandem toward a singular goal: discovering the secret that Curiosity's creator says awaits one lucky player inside. That's right: After millions of man-hours of work, only one player will ever see the center of the cube.
Curiosity is the first release from 22Cans, an independent game studio founded earlier this year by Peter Molyneux, a longtime game designer known for ambitious projects like Populous, Black & White and Fable.
Players can carve important messages (or shameless self-promotion) onto the face of the cube as they whittle it to nothing. Image: Wired
Molyneux is equally famous for his tendency to overpromise and under-deliver on his games.
In 2008, he said that his upcoming game would be "such a significant scientific achievement that it will be on the cover of Wired." That game turned out to be Milo & Kate, a Kinect tech demo that went nowhere and was canceled. Following this, Molyneux left Microsoft to go indie and form 22Cans.
Not held back by the past, the Molyneux hype train is going full speed ahead with Curiosity, which the studio grandiosely promises will be merely the first of 22 similar "experiments."
Somehow, it is wildly popular. The biggest challenge facing players of Curiosity isn't how to blast through the 2,000 layers of the cube, but rather successfully connecting to 22Cans' servers. So many players are attempting to log in that the server cannot handle it.
Some players go for utter efficiency, tapping rapidly to rack up combo multipliers and get more
Now this would be really cool if it had a brain computer interface and could be controlled by a trained drummer's mind!
Science and Technology Society and Culture Georgia Institute of Technology researchers have built a wearable robotic limb that allows drummers to play with three arms. The two-foot long "smart arm" can be attached to a musician's shoulder. It responds to human gestures and the music it hears.
We are living in the future when live broadcasts are being censored by AI programs in real-time.
I'm sure dictators everywhere are looking forward for these technologies to mature. Having a firewall over reality is so convenient.
What this tells is that we should not take AI seriously until smart Luis's (or his son) managed to make something decent out of it ...
"This was, of course, absurd. First of all, the clips had been provided by the studios to be shown during the award ceremony. The Hugo Awards had explicit permission to broadcast them. But even if they hadn't, it is absolutely fair use to broadcast clips of copyrighted material during an award ceremony. Unfortunately, the digital restriction management (DRM) robots on Ustream had not been programmed with these basic contours of copyright law.
And then, it got worse. Amid more cries of dismay on Twitter, Reddit, and elsewhere, the official Worldcon Twitter announced:
Chicon 7@chicon_7
We are sorry to report that #Ustream will not resume the video feed. #chicon7 #hugos #worldcon

And with that, the broadcast was officially cut off. Dumb robots, programmed to kill any broadcast containing copyrighted material, had destroyed the only live broadcast of the Hugo Awards. Sure, we could read what was happening on Twitter, or get the official winner announcement on the Hugo website, but that is hardly the same. We wanted to see our heroes and friends on that stage, and share the event with them. In the world of science fiction writing, the Hugo Awards are kind of like the Academy Awards. Careers are made; people get dressed up and give speeches; and celebrities rub shoulders with (admittedly geeky) paparazzi. You want to see and hear it if you can.
But Ustream's incorrectly programmed copyright enforcement squad had destroyed our only access. It was like a Cory Doctorow story crossed with RoboCop 2, with DRM robots going crazy and shooting indiscriminately into a crowd of perfectly innocent broadcasts."
not much new that has not been shared here before ... BUT: we have done relativley little on any of them. for good reasons?? don't know - maybe time to look into some of these again more closely
Energy Efficiency(
Termite mounds inspired regulated airflow for temperature control of large structures, preventing wasteful air conditioning and saving 10% energy.[1]
Whale fins shapes informed the design of new-age wind turbine blades, with bumps/tubercles reducing drag by 30% and boosting power by 20%.[2][3][4]
Stingray motion has motivated studies on this type of low-effort flapping glide, which takes advantage of the leading edge vortex, for new-age underwater robots and submarines.[5][6]
Studies of microstructures found on shark skin that decrease drag and prevent accumulation of algae, barnacles, and mussels attached to their body have led to "anti-biofouling" technologies meant to address the 15% of marine vessel fuel use due to drag.[7][8][9][10]
Energy Generation(
Passive heliotropism exhibited by sunflowers has inspired research on a liquid crystalline elastomer and carbon nanotube system that improves the efficiency of solar panels by 10%, without using GPS and active repositioning panels to track the sun.[11][12][13]
Mimicking the fluid dynamics principles utilized by schools of fish could help to optimize the arrangement of individual wind turbines in wind farms.[14]
The nanoscale anti-reflection structures found on certain butterfly wings has led to a model to effectively harness solar energy.[15][16][17]
Energy Storage(
Inspired by the sunlight-to-energy conversion in plants, researchers are utilizing a protein in spinach to create a sort of photovoltaic cell that generates hydrogen from water (i.e. hydrogen fuel cell).[18][19]
Utilizing a property of genetically-engineered viruses, specifically their ability to recognize and bind to certain materials (carbon nanotubes in this case), researchers have developed virus-based "scaffolds" that
Development of biodegradable batteries to power medical devices that you could inject into the human body, for example to do medical checkup, drug delivery etc
Using the angular momentum transmitted by an internal flywheel as an impulse, these cubes can move, jump, roll across the ground and climb over and around one another. They stick together using a set of small magnets, smart !
That is indeed a great way of using modular robots to build larger structures. I think we did bump into this some time back, but never really considered it much. Considering now the working group on structure assembling, I think we should add it to the list of building strategies and seriously consider it.
This guy solved a problem many people are trying to solve!!! The optimal control problem for the three body problem (restricted, circular) can be solved using continuation of the secondary gravity parameter and some clever adaptation of the boundary conditions!! His presentation was an eye opener ... making the work of many pretty useless now :)
hmmm, last year at the AIAA conference in Toronto I presented a continuation approach to design a DRO (three-body problem). Nothing new here unfortunately. I know the work of Caillau, although interesting what is presented was solved 10 years ago by others. The interest of his work is not in the applications (CR3BP), but in the research of particular regularity conditions that unfortunately make the problem limited practically.
Look also at the work of Mingotti, Russel, Topputo and other for the (C)RTBP. Smart-One inspired a bunch of researchers :)
Topputo and some of the others 'inspired' researchers you mention are actually here at the conference and they are all quite depressed :) Caillau really solves the problem: as a one single phase transfer, no tricks, no misconvergence, in general and using none of the usual cheats.
What was produced so far by other were only local solutions valid for the particular case considered.
In any case I will give him your paper, so that he knows he is working on already solved stuff :)
Ah! with one single phase and a first order method then it is amazing (but it is still just the very particular CRTBP case).
The trick is however the homotopy map he selected! Why this one? Any conjugate point?
Did I misunderstood the title ?
I solved in one phase with second order methods for the less restrictive problem RTBP or simply 3-body... but as a strict answer to your title the problem has been solved before.
Nota:
In "Russell, R. P., "Primer Vector Theory Applied to Global Low-Thrust Trade Studies," JGCD, Vol. 30, No. 2", he does solve the RTBP with a first order method in one phase.
I also loved his method, and it looked to me that is far more general than the CRTBP. As for the title of this post, OK maybe it is an exageration as it suggests that no solution was ever given before, on the other end, as Marek would say "come on guys!!!!!"
The generality has to be checked. Don't you think his choice of mapping is too specific? he doesn't really demonstrate it works better than other. In addition, the minimum time choice make the problem very regular (i guess you've experienced that solving min time is much easier than mass max, optimality-wise). There is still a long way before maximum mass+RTBP, Topputo et al should be re-assured :p
Did you give him my paper, he may find it interesting since I mention the homotopy on mu but for max mass:)
Joris, that is the point I was excited abut, at the conference HE DID present solutions to the maximum mass problem!! One phase, from LEO to an orbit around the moon .. amazing :)
You will find his presentation on line.... (according to the organizers)
I gave him the reference to you paper anyway, but no pdf though as you did not upload it on our web pages and I could not find it in the web. So I gave him some bibliography I had with be from the russians, and from Russell, Petropoulos and Howell, As far as I know these are the only ones that can hope to compete with this guy!!
If you send me the pdf I can give it to the guy .. the link you gave contains only the first page ... (I have no access till monday to the AIAA thingy)
What do you mean by this comment, Leopold? ;-)
Jokes apart: I am following the Diigo thingy with Google Reader (rss). Obviously, I am getting the new postings. But if someone later on adds a comment to a post, then I can miss it, because the rss doesn't get updated.
Not that it's a big problem, but do you guys have a better solution for this? How are you following these comments?
(I know that if you have commented an entry, then you get the later updates in email.)
(For example, in google reader I can see only the first 5 comments in this entry.)
and on your problem with the RSS Tamas: its the same for me, you get the comments only for entries that you have posted or that you have commented on ...
I have an account with them since 30 June 2014 - nice but since I don't like webmail I prefer using mail with PGP installed ... unfortunately very few others are using PGP encryption .... even smart ACT guys ... :-(
nice indeed ....
especially like:
"They make such great stuff, but they're such assholes. Do I really want to support this company?
Should Apple care what people like me think? What difference does it make if they alienate a small minority of their users?
There are a couple reasons they should care. One is that these users are the people they want as employees. If your company seems evil, the best programmers won't work for you. That hurt Microsoft a lot starting in the 90s. Programmers started to feel sheepish about working there. It seemed like selling out. When people from Microsoft were talking to other programmers and they mentioned where they worked, there were a lot of self-deprecating jokes about having gone over to the dark side. But the real problem for Microsoft wasn't the embarrassment of the people they hired. It was the people they never got. And you know who got them? Google and Apple. If Microsoft was the Empire, they were the Rebel Alliance. And it's largely because they got more of the best people that Google and Apple are doing so much better than Microsoft today.
Why are programmers so fussy about their employers' morals? Partly because they can afford to be. The best programmers can work wherever they want. They don't have to work for a company they have qualms about.
But the other reason programmers are fussy, I think, is that evil begets stupidity. An organization that wins by exercising power starts to lose the ability to win by doing better work. And it's not fun for a smart person to work in a place where the best ideas aren't the ones that win."
Poor programmers can complain, but they will keep developing applications for iPhone as long as their bosses will tell them to do so... From my experience in mobile software development I assure you it's not the pain of the programmer that dictates what is done, but the customer's demand. Even though like this the quality of applications is somewhat worse than it could be, clients won't complain as they have no reference point. And things will stay as they are: apple censoring the applications, clients paying for stuff that "sometimes just does not work" (it's normal, isn't it??), and programmers complaining, but obediently making iPhone apps...
Darpa-backed electrical engineers at the two schools released the stunning results: a shape-shifting sheet of rigid tiles and elastomer joints that can fold itself into a little plane or a boat on demand.
In Darpa’s dreams, this work will eventually lead to everything from morphing aircraft to self-styling uniforms to a “universal spare part.”
Researchers in Canada have created a new material that mimics the brilliant iridescent colours seen in beetle shells. As the eye-catching effect can be switched off with the simple addition of water, the researchers believe their new material could lead to applications including "smart windows".
