AVRs are Amazing

To add to all the other reasons I love AVRs (cheap, featureful, good development tools, beautiful assembly language), they are now also to be considered almost impossibly resilient: I just made a mistake and reverse biased an ATTiny13 micro (swapped Power and Ground wires), causing it to heat up until it was too hot to touch… I just popped it back in the programmer after it cooled down, and it is completely fine. Win, atmel, win.

Bored Should be Obsolete

The collexion meeting tonight had a discussion basically on the idea that no one should be ever be bored anymore, because there are so many cool things one could be doing. My current list of things I want/need to spend time on, ignoring the mundane:
* Working on my SmartLEDs project [If I remember, I’ll edit to a link to the pending project page once I put it up]; the basics are almost done (software PWM for color mixing, etc.), next I want other people playing with it too and try different sensors and behaviors and diffusers and such.
* Getting started with the LARs stuff my masters project is based around; I think I want my first major contribution to be a behavioral-level software simulator for a full implementation of the proposed architecture. If I’m feeling really bold it might be parallelizable to run on the big machines (or their smaller, older siblings). I suspect before that I will be working on cleaning up my predecessors’ mess, and helping to get their SC paper out the door.
* Continuing to start up my desktop CNC mill project; I want to try to build one for <$200, and I get to write off the time and money guilt as school activity, as the XY table component will serve as the class project in EE572/Digital controls for myself and two other students. I’m getting a good feel for parts and designs, going for something not dissimilar to this.
* Arranging my CGS500 final project, I’m fairly sure I’ll be doing it on UI/UX, and supporting analysis of current and notable historical examples of computer interfaces with articles (using The Humane Interface as a jumping off point for the analysis). I think it would be REALLY fun to do it as a heavily multimedia presentation, with virtual machines running different systems and applications to demonstrate interspersed with the slides, but I’m afraid it would detract from the depth and be difficult to do gracefully.
The consensus was that bored people are boring; there’s really no excuse for not being able to come up with things you want to do, especially with the power of the internets focused through places like make and hackaday to use for inspiration.
I had to type this post TWICE because flatpress failed me when I accidentally hit shift+back and navigated back without saving. Flatpress is really not an ideal engine, the “Post to the date when the draft is created, not when the post is posted” misfeature drives me nuts, but I still can’t fault it for being easy to deploy in space I don’t have to pay for.

Hugo Award Nominees

This year’s Hugo award nominees are up. The big thing to note is how many of the entries have “read online” links next to them.

The only novel nomination I’ve read is Cory Doctorow’s Little Brother which, while definitely not high-end prose (its usually classified as young-adult fiction), is something everyone should read RIGHT NOW to understand the way our paranoid society and technology interact. Seriously, go, right now, Free in your format of choice or on dead trees from a bookstore. It’ll only take a couple hours at most. I also find Anathem promising; its on my reading list, but I haven’t got to it yet and doubt I will for some time.

Otherwise, I’m not terribly impressed by most of the options, too many of the nominees are derivative, or adaptations, even down into the short stories. Some of them are very good adaptations, and many of them are very enjoyable if you’ve read the precursors, in particular, “Shoggoths in Bloom” is good fun if you’ve read “At the Mountains of Madness” (Available here via Aussie copyright law and Project Gutenberg) or any of Lovecraft’s related works. I’m working my way though the ones with read links, thus far “26 Monkeys, Also The Abyss” is the most original thing in the collection, both in terms of content and format. The format and diction is genuinely bizarre, but I found it well suited to the story and the context of reading it online.

All of this has happened before. All of this might happen again(?)

The end of the Battlestar Galactica TV series just finished, and it is a satisfying end to the most impressive piece of film SciFi (distinct from syfy, you audience-alienating douchebags) in years. I put it on footing with Babylon 5 and Firefly, my other two favorite SciFi TV series. Not going to spoil here, I usually torrent and watch later myself, and respect those who chose to. The thing that puts it above the rest isn’t so much the premise or plot (although both are good), it’s that the acting and writing and scoring (especially the scoring) is spectacular.
It’s basically beyond ruin at this point, even if The Plan (movie, tells parts of the story from the cylon’s perspective) and Caprica (TV series, tells the story of the creation of the cylons), the remaining two planned bits of the franchise are crap, it will still have been a great run, making it one of those rare TV series that is good as (far) more than background noise.

Lexington’s Unsightly Hole

The hackers have been meeting up at third street stuff (my second favorite coffee house after Common Grounds)on weeknights for a while, which means I walk by Limestone and Vine most afternoons right past this:
unsightlyhole_sm.jpg
the unsightly hole in the middle of Lexington’s downtown. Every other time I walk by it seems like someone comments on it, usually asking where The Dame has moved.
Everyone remotely alert living in Lexington is reasonably familiar with the hole, it used to be a block that contained interesting things; Mia’s, Busters’, The Dame, The Mad Hatter, etc. It is now the future site of the Webb companies CenterePointe project (yes, with TWO unnecessary ‘e’s), a 550ft mixed-use monstrosity which has been the source of endless controversy. This UrbanOhio thread (I don’t know anything about the site) has aggregated most of the news on it. Take a look at the renderings for the current design:
centerepointe.jpg
My two thoughts are that the design would be hilariously phallic if it weren’t about to become the tallest building in Kentucky, squarely in the middle of Lexington’s downtown, and that it, quite appropriately, looks like it’s giving the city the finger. It’s actually a little toned down from the earlier renderings in that regard.

The fact that the previous big, ugly, overpriced mixed-use structure put up in Lexington (Center Court) was such a resounding success that even Starbucks moved out should give a good idea of what the demand for that kind of space is in the area. One small high point, I am pleased to see that the current revision is going to have drastically more meeting space in the Marriott-managed hotel that is planned as one of the primary tenants, that space could be used to host conferences and keep the hotel alive after the Equestrian Games are over in 2010 (assuming the damn thing is even done by then), and Lexington goes back to having little demand for a giant hotel in the middle of the city.

Cybernetics and the Technological Singularity

Over the last few weeks I’ve seen a remarkable amount of news about cybernetics, and I haven’t been actively looking. The first piece was about a removable replacement eyeball installed in a blind man. The eye is not entirely functional, but does allow for partial (low resolution, spotty, grayscale) sight by interfacing an external camera to an artificial retina. Serious Brain-Computer interfaces like the synthetic retina have been appearing for about a decade, ranging from mostly useless, totally noninvasive devices like the various headband products sold as novelties to life-changing technology like the above.

A one-eyed filmmaker also had a bionic eye implanted. This one isn’t for the wearer’s benefit; it allows for wireless recording to provide a literal view through his eyes. The camera mechanism itself is internal and looks as natural as any prosthetic, allowing the wearer to interact as though he were not wielding a camera.

For the scifi dorks, in the latter episodes of Bayblon 5, G’kar had an eye which worked like the sum of the above; it was removable and wireless, but he was also able to see through it. It seems like that is the real yearning behind both projects; restorative, wireless, and shareable.

The next article I came across was in last month’s IEEE Spectrum, an article on the state of prosthetic arms (apologies if it tries to paywall you, for an organization for technology professionals, IEEE’s web presence is full of suck and fail), written by an engineer who lost his lower arm in Iraq, and was so disappointed by the selection of products on the market he joined the (DARPA-funded) efforts to develop next generation systems. He notes that the market for prosthetics is commercially unattractive, as there is only a minuscule need for any particular part, and suggests the remedy is open standards (for how the various prosthetic parts attach and communicate), and crossover technologies co-developed for mass market segments, such as interfaces with HCI (he says “video game controllers”, which I find horrifyingly disingenuous) and mechanical parts with robotics.

The last encounter was also about prosthetic limbs; (another) TED talk by Aimee Mullins a multi-talented woman who is missing her legs below the knee and uses a variety of prosthetics to adjust her appearance and abilities. The interesting part isn’t the particulars of the legs; it’s the way she and others perceive the legs. I’m going to go ahead and verbatim quote the end of Mullin’s talk, because it sums up the idea at least as eloquently as I could:

The conversation with society has changed profoundly in this last decade. It’s no longer a conversation about overcoming deficiency, it’s a conversation about augmentation; potential. A prosthetic limb doesn’t represent the need to replace loss anymore. It can stand as a symbol that the wearer has the power to create whatever it is that they want to create in that space. So, people that society once considered to be disabled can now become architects of new identities and indeed continue to change those identities by designing their bodies from a place of empowerment.

And, what is exciting to me, so much, right now, is that by combining cutting edge technology (robotics, bionics, etc.) with the age old poetry, we are moving closer to understanding our collective humanity. I think that if we want to discover the full potential of our humanity, we need to celebrate those heartbreaking strengths and those glorious disabilities that we all have. I think of Shakespeare’s Shylock: “If you prick us, do we not bleed, and if you tickle us, do we not laugh.”

What this all naturally leads to, at least for me, is my beliefs about the technological singularity. People usually consider that it will happen in one of two ways, artificial intelligence will surpass human capability (Strong AI), or people will be augmented beyond their current capabilities (Transhumanism, usually via technological augmentation (like this, another TED talk from people at the Media Lab, this one about awesome wearable augmented reality gear)). I believe firmly in the latter; we’re not going to build a better intelligence by trying, usually poorly, to replicate a human in devices which are poorly suited to the job. We can however build devices which are better suited to particular tasks than humans, and, if the interfaces between humans and these devices can be made adequately transparent, use them to augment human(?) capability far beyond current limitations.
My other big thought on the matter is that the singularity won’t be a quantum leap, and isn’t going to be something we know when happens; humans won’t be the top dog Monday night and superseded Tuesday morning; it will be something our augmented “superhuman” progeny look back and try to find a moment to assign as the turning point, just like every other incremental, iterative improvement in technology which has resulted in a leap in society as it permeated into our lives.

Dorkbotlex #1

3359235534_1cdf0bd6fd.jpg?v=0
I went to dorkbotlex last Saturday (pi day!) and just got around to flickring the (few) pictures I took. Flickr set here. There are also some videos on their tumblr page.
As always, it makes me really happy to see signs of geek culture in Lexington.

I am Psychotic.

I definitely just made another editing pass on a paper that I got an A on and have no plans to resubmit anywhere, just because I wasn’t happy with it. Urgh. The link is updated in the Multiracial Cognition post.

Misc. Photoblogging

I found a couple nifty one-off images when I was cleaning out my camera’s memory card and decided to shrink (10MP is not blog sized) and post them. Midsize images linked from images in post.

Image 1: My room has a really nice view of the Lexington skyline. Picture taken sometime during the ice storm this year. (For anyone trying to figure out where I live from the image… taking advantage of UK’s lack of a coherent privacy policy is way easier)
WinterWindow_sm.jpg

Image 2: Roughly the same view out the window, but this time in better weather, and playing with ISO/Exposure/Etc. settings on my camera (a Cannon SD770IS, with which I am quite pleased). This is the best of about 20 shots out the window, ranging from leaving the camera on full auto to manually setting the exposure length/ISO speed/color balance, and a bunch of other things I’m still vaguely surprised can be set manually on a compact point-and-shoot. Considering how bad Canon compacts tend to be in low light I’m pretty impressed with the image I got, even if it did take a while to produce it. I’d still like to figure out how to get around the noise/grain.
window_sm.jpg

Image 3: The schlumbergera I plant-napped when I moved last summer bloomed the other week. It seems to like the spot on the mantle in my room (next to an outside wall, they require cool to bloom) and watering schedule I have it on; it had a good growth cycle earlier in the year, and is now blooming. (disclaimer: All parties involved seem to consider it justified plantnapping, I had been taking care of it since before I lived with it.)
schlumbergera_sm.jpg

The latter picture is one of the rare occasions when the macro mode on my camera worked properly when presented with a significant depth of field. In a related matter, the SD770 is finally becoming supported by CHDK so I can get the awesome extra features I was presuming would happen when I bought it. As soon as I get some time I’ll have to set up one of my spare SD cards and try it out.

Multiracial Cognition

As promised, my CGS500/CS585 survey paper on research into cognition in multiracial individuals. (PDF) (PDF, edited)
The material is good, and the basic organization is sound, but I don’t really feel like it’s a particularly good paper; the quality of the writing and the low-level organization both feel a little sub-par. This may be because I did the last couple rounds of writing and editing while drastically overtired (illus: I misread the regression line in the graph, so the 2009 extrapolated US multiracial population is wrong, it should be 13 million). It may also just be that I have a horribly warped set of standards.

The part I really enjoyed, almost to the detriment of the paper itself, was the precursor research. Once I got into the appropriate lingo and started following references I found that there is a reasonable body of research into multiracial persons. I could have happily spent another month heading down the referential rabbit hole and wallowing in reading material. I found a great many things which were either familiar or explanatory to my own identity. In particular, it brought to mind an experience I’ve long found a little peculiar; last time I was in Hawaii, I started talking to the Pleasant Holidays rep (we bought our hotel on Oahu as a package), who was also hapa-haoli, almost as soon as I got off the plane, and had mostly re-normed to a local accent in 5-10 minutes. She was the first of several people to ask me, usually unprompted, how long I had been away [from Hawaii] as though I was local (”Local” is specially connotative there). I’m reasonably sure I’ve experienced the same effect earlier times my family has been out on the Islands, but just not been aware of it. My take is that it is an example of the hypothesis of several of the articles I read; that the lack of a same-race peer group for almost all mixed race individuals weakens our feeling of normative pressure/belonging, and causes a sort of low-level stress, so the sudden presents of other hapa-haolis puts me at ease and causes me to immediately begin conforming.

The other thing I really got out of this paper is the degree to which publishers are an impediment to the availability of information. Particularly disgusting is the LA Times article on president Obama’s multiracial background used for example material; the article was referenced elsewhere, which lead to a paywall, so I tried to use UK’s LexisNexis and Newsbank subscriptions… which refused to turn up a year-old article. I then put the article title into google, and the article in question came up in unencumbered full-text directly from the LA Times page. This is basically the same problem story of ILL hate from earlier in working on the paper. I don’t seem to run into this problem as much with computer and engineering topics, but I suppose that is jointly the result of us all being habituated to working around copyright, and the fact that the vast, vast preponderance of articles in the area are published by IEEE, to who’s publications I have ready access.
