You clearly put a lot of work into it! I added a link to it from my blog (bluntbody.com). What sort of FOV do you get with those loupe magnifying lenses? Just wondered how it compares to the Rift. I imagine that to get the large FOV on the Rift it uses something more complex such as this... http://www.vrtifacts.com/hmds/awesome-vr-optics-for-1-class-displays-at-less-than-ten-dollars/ Keep up the good work!

It is currently happening but not fast enough. The worst I have seen recently is regarding the way the Chinese sap bile from bears stomachs, they go to the extent of sewing a metal plate onto the bears stomachs to stop them from committing suicide from the pain. There are advocacy groups that put out campaigns that plead with people to support causes, but this just kind of pleading seems so vastly disproportionate to the amount of injustace that is currently being enflicted. What we really need are complete paradigm shifts that force us to transform our sociological standards. I believe there are ways to do this. One way would be to start some sort of agency that publically promotes multinational corporations and their philonthropic effots. See it as advertising for the company. Personally I would be much more inclined to purchase a bottle of coke over a pepsi if I knew that coke had transfered its signage advertising budget for just one day into some kind of cause for good. Once the multinationals get on board that every company underneath them will be forced to adapt and cashflow will have a direct correlation to good will. There are so many variables also in this chaotic world. One individual who lives in Africa on 50c a day might consider themselves lucky they can eat, yet we consider ourselves lucky when we get a new iPhone. Change needs to come and intelligent people like yourself are required to make it happen, to envisage methods and concepts to awaken our society. In the same way you are able to build your precise contraptions, you can also muster up new ways of affecting change for good.

]]> Comment on In Defense of Efficient Computing by Ken Dakin http://bitcortex.com/2009/05/25/in-defense-of-efficient-computing/#comment-39 Ken Dakin Mon, 12 Sep 2011 17:58:38 +0000 /2009/05/25/in-defense-of-efficient-computing/#comment-39 Rod, I completely agree with your article and always wonder where people are coming from when they happily waste resources just because they can get away with it. Having faster processors is good because we can do lots more work for the same cost (or get faster answers to time critical questions) - not because we can acheive the same result by allowing ourselves to get lazy. I agree that for one-off programs that are run a couple of times it doesn't matter too much - but one-off programs have a tendency to outlive their creators and get modified to create more one-off programs that may also persist. This way lies madness (non-maintainable code that is both inefficient and inconsistent). For production programs we should construct solid frameworks that are as efficient as possible (and as re-useable as possible unless this conflicts with performance to a great extent). Most of the programs and sub-routines I produced over 40+ years were written with efficiency constantly in mind and yet they also had close to zero bugs and needed few changes if any over their very long lifetimes of 20 years or more. I produced instruction set simulators for test/debugging purposes where zero tolerance was the only option (otherwise the products would have been worse than useless and given false positives). I would like to say that I very much enjoy your blog and I am as impressed, as you clearly are, by the awe inspiring JFK speech which always gives me goosebumps each time I see it. My own wish is that world leaders get together soon and jointly commit to setting up a base on Mars by 2030 say. This might also kick start the world economy for years to come and inspire a new generation like nothing else could. My audacious vision is that we should send self assembly robots to carve out an underground base first using only materials to hand (e.g. to fashion most of the 'boring components' out of natural rock for instance - at ever increasing scales) and follow this with a manned expedition to secure and populate the prepared space. Rod,

Also clever frameworks for taking like you say complexity in the universe and boiling it down to something simple is where the innovation happens.

I think we will have a connectome (wiring diagram) of the human brain within 4-7 years. Once we have that, it will become easier to construct better brain computer interfaces. A BCI could communicate with brain cells using optogenetics or perhaps ultrasonic neuromodulation. Modifying consciousness with neurotechnology should be awesome as well (Paradise engineering). I did a post about BCI's and the wireless neurosociety a while back on my own blog that covers related material. Nice post.

The numbers of relevant published US patent applications were merely 23, 11 and 13 for 2009, 2008 and 2007, respectively. This represents mostly technological imaturity. One may claim that most researchers nowadays believe in open sharing and don't even bother filing for patents. I still think the numbers are so low because nothing much is actually happening and the significant breakthroughs we are all awaiting are yet to come. As the comercial impact is going to be huge I'm certain companies as well as universities will protect the IP by all means and thus IP is a good indicator. BTW, are you aware of a serious (evidence-based) forecast that aims to project when we'll truly be utilizing BCI in big numbers? I'm not referring to the rather 'low-hanging-fruits' but to more complex applications that would revolutionize our lives. I tend to agree they will arrive but later than most 'futurists' predict.

The thing about I/O, though, is that output is typically much easier than input. We see this with modern robotic prostheses. Getting a person's nervous system to move a robotic arm around is easier to do than getting the person's brain to recognize where the arm is located in space and whether it is touching anything, is hot or cold, etc. I think we will have reliable output devices--things like the "interceptors" in Ghost in the Shell, devices that tell whether a person is recalling or fabricating a "memory," etc--well before we have reliable input devices. Indeed we already have lots of pretty good output devices while inputs like bionic eyes are coming along more slowly and inputs to non-sensory functions such as language are basically still on the drawing board. Not that this is a terrible situation, I think we can get a tremendous amount of usefulness from output devices alone, especially output devices that let us study brain data in real-time. I'm currently obsessed with the research being done on monks who have practiced many thousands of hours of meditation and how their brains are different. Also think output combined with feedback through a traditional computer screen might enable an entirely new method of learning things and, if capable of outputting what a person is imagining in her "mind's eye," a way of helping people learn how to visualize things better. Anxiously waiting for my ACME home brain scanning device. Great post Rod. The thing about I/O, though, is that output is typically much easier than input. We see this with modern robotic prostheses.
