Saw a lecture by Tobi Delbruck at my uni last month and was really impressed by this application among others. Seems like some really interesting technology. Can post a link to the lecture recording (audio) if anyone wants it?
Ben Kuipers takes us through his investigations to date on the subject of robotic cognition - using some very adorable footage of a "research student" (actually the students 2yo son) to show just how far we have yet to go. Focusses on the "grasp" function of human object interaction. Bit slow in places as it's just audio and the slides were important, but could help someone find further information.
Sorry for WMA, it's the native format my dictaphone uses =S
There is another up there for linguists - Geoff Ketland discusses his notion of language as platonic solids... I found it VERY interesting stuff.
Note: I'll keep them up for a week or two in case anyone is interested, but I'll be using the domain for something soon, so can't provide permanent links.
"dissociative identity disorder/multiple personality disorder" has been all but dropped by mainstream psychology. It's considered to be an artifact explained as being induced by a number of factors including attention seeking, desire to please therapist, extreme hypochondria and mimicry.
Whether or not it has been dropped by mainstream (source?) - you paint dissociative identity disorder in such a poor light - choosing only to focus on characteristics that make it controversial. I think you'll find that in fact there is simply a lack of consensis amongst psychologists for its basis - which happens to be the case for many 'disorders' in this arena.
As with many mental illnesses, whether or not it's real depends on what your definition of 'real' is. It's clearly a common pattern of behavior that's secondary to other factors, but you could say the same thing about lots of mental illnesses.
A possible title for such an article is a word I first read about when reading Isaiah Berlin and his students for some philosophy of mind work I was doing a few years back. The term they use is "Einfuhlung", which translates to a "feeling into" (empathy?) but one that is quite directly experienced. Thay claim that one cannot feel and be moved by the depth of woe (or any other emotion, for that matter) in a blues song, for instance, without having experienced it firsthand.
Once again the YC community surprises me in both it's depth and it's breadth. From someone who has found your (and Russell's) text invaluable, I say - thank you, sir.
And thank you PG/YC for giving me the opportunity to do so.
Can a gyroscope in this situation prevent tipping, or does it merely slow it down? Honest question. Possibly even just slowing it down a lot would be sufficient since other forces could be brought into play to stabilize the boat.
I think you guys are putting way too many obstacles in the path. I live on a boat and I just moved a waterheater (~120 kilos) from port to starboard and it didn't make much of a difference on the waterline of the boat.
Yeah, I thought as much as well. It was said more in jest. I know a guy who put tonnes (3 or 4 I think) of slate tiling in his stern end and it only dropped it down half a foot or so in the water. Narrow boats usually have a flat bottom and weigh a huge amount, so they are pretty resillient... still, gyroscopes are interesting
I highly recommend a hammock to anyone that is wanting to save space. I slept in one for 2+ years, and haven't found anything as comfortable since. It takes a little while to get used to, but it's great for your back - despite what you may think.
Ahmen, I'm aware of my inability to grasp "design" myslf, but it's application by skilled tradespeople always delights me. When I found AL I too spent unreasonable amounts of time trawling through it all! My favourite would have to be the studio lavatories: http://www.artlebedev.com/everything/toilets/
Wasn't going to post as I struggle to justify the relevance of the parent and my response to the community, but think it's ultimately of little consequence and the words themselves are important to me, so...
~OT: I once worked as a charity fundraiser and had more than a few encounters with homelessness, one of which (a few years after leaving the job) left me quite stunned. The company was a bit of a stop-gap for those that could and would handle it, with accommodation, food, and a pretty interesting lifestyle all thrown in.
I once found myself in a pub, however, and a homeless guy came up and asked me for a bit of spare change. Having built up a healthy respect for people and torn down my impulse to judge on the basis of only a very small amount of information (from my exp. in said job), I gave the guy what I could when, looking in his eyes, I saw my friend. A guy I had worked with as a fundraiser, who, after a brief spell of bad luck had fallen through the gaps of society and ended up having to constantly climb. I did what I could for the guy, but more importantly he did so much for me - I had never realised destitution was so close (or that the climb back up was so high).
Another time I met something I can only describe as otherworldly.... it was almost sacred. Take what you will from it. I was approached (this was while fundraising) by a small, fat, black guy in comfortable, though slightly disheveled clothes in his late 50s or thereabouts. As he came close it occured to me that he didn't exist... I honestly cannot understand the instantaneous clarity of that thought... maybe he was just too much of a cliche for my mind to deal with, but there was something more, an aura that came from somewhere deep within him, from somewhere I don't think I have. He took my hand and started talking to me as though it was the most ordinary things in the world, and he proceeded to tell me about his pebble. He'd been fondling it in his other hand and as I noticed it he started telling me about where he'd found it and all the things that could have been while that pebble had remained hidden. And that, he said, was his point. My pebble was currently hidden, and I was close to finding it. It could be a stone, a coin, a woman or even the world! The point was that it was mine and that it had been sitting, passive, until the day I, and I alone, would come across it and bind myself to it...
I don't even know why that's worth sharing with you. Most people I tell, I'm sure, just think I was seduced by the romantic ramblings of a mad old man... maybe so, but I think that moment, myself, the old man and what he said deserve a great deal more dignity, even divinity, than that. I choose to make that moment spiritual (and I'm not by any means "religious")....
Herman Hesse - The Glass Bead Games (though I would hazard to say any of his famous five are worth reading - haven't got round to them all myself yet, though)
I read The Glass Bead Games after I happened across Timothy Leary's "The Politics of Ecstasy" (a good read but not great - his ignorance/arrogance get's in the way all too often). The thing that switched me onto HH was TLs insistance that the man had achieved enlightenment: I figured that was not to be missed!
HH won the Nobel Proze for literature shortly after it's publication, and I cannot overstate the majesty of this book - it is simply awe inspiring. Easy to read, with a persuasive storyline that seduces the reader into an abominably utopian world of intellectual rule (Epistocracy?).
I won't ruin it for any readers. The basic thrust of the tale is the student becoming the master in a world where the highest grand masters (of "the game") are revered with something approaching religious zeal.
It changed me. Fundamentally. Before reading it I was naive and starry eyed about what education could achieve, now I'm more aware than ever that humanity, educated or not, is still just a many faced beast. All these trappings of wealth, power, and intellect are just reigns temporarily thrown around this rampaging behemoth.
It's not so much an epiphany of despair or futility, strangely it is somehow quite the opposite. It's a realease. I can't quite explain it. It's something that sends me into wild flights of lyrical rhetoric about the nature of humanity and my own part in it. I don't think there is anything better that you can ask from a book.
Find a video of this Blackhat talk from 2005. Pretty sure it's in the iTunes store in the podcast section. The video covers pretty much everything you need to know about the theory of such systems.
As far as actual implementation, I'm not aware of a system that does this. Although honestly some researcher has probably implemented such a system in a paper somewhere. There's probably a commercial network IDS that does it too. I haven't been doing this long enough to be an expert in the field, so I can't confidently say what the true state of the art is in behavioral detection. I'm pretty sure there are no open source projects though if that's what you're asking.
If you're thinking about implementing your own, I'd say start at the network level and write a simple program that sets an alarm off when a specific host starts responding to HTTP requests. If you want to get complex, use Wireshark to log all your network traffic for a month. You can then use Bayesian learning to determine whether new traffic is out of the ordinary. SSH traffic is problematic, so if you need to allow such traffic you'll have some additional challenges to overcome.
Starting an open source project related to this is on my TODO list, but I'm focusing on demonstrating the
hopelessness of signature based detection first.
Good luck. And thanks for the links, I'll be looking into it. You mind a PM if it get's interesting (just to bounce ideas off someone)? I'm looking into machine learning stuff myself and can imagine some interesting integrations with this subject.
I'm presenting a metamorphic engine at a hacking conference in April (http://thotcon.org/). It'll be completely open source. Initial tests against modern anti-virus look very good. ;)
