Bioengineering is faster and cheaper than terraforming

My news aggregator handed me a Slashdot article about terraforming Mars and other planets. One of the points raised was that terraforming, while possible, would be very slow and expensive, taking thousands of years before a stable biosphere was achieved. Perhaps nanotechnology might speed this up a bit but re-engineering a planet, moving its orbit, dragging a moon to it if needed, getting the right moisture and pressure balance, and so on and so on is an incredibly complex task.

Seems much simpler and much faster to re-engineer humans instead:

  • Design them so as thrive in Mars’s low gravity.
  • Design to them to have collapsible lungs like dolphins so as to take a few hours between breaths.
  • Make them symbiotic with tough, oxygen producing plants, perhaps “eating” the plants oxygen.
  • Give them thick, metal scaled hides to resist Mars’ intense ultraviolet radiation.

In the end, just like Ray Bradbury and Fred Pohl said, we will be the Martians, with old Earth as the hostile and alien environment. To colonize space, human is going to have to diversify into new, artificial species.

Or maybe what will happen is the ultimate naturalization process. As space travelers move from world to world, they’ll spend a few days in a vat before planetfall to acclimatize themselves. Nanoscopic robots in these vats will rewrite their bodies atom by atom so that they can thrive on the worlds they visit or colonize. If they return to Earth, they revert back to venerable ol’ homo sapiens.

Science fiction novels have already explored this but, perhaps not as much as they should have. Each time space travelers changed their bodies, this would have profound mental effects. Perhaps some bodies would be more fun to inhabit than others. Or maybe, after the novelty wears off, one body will be as boring as the next. Something weird to think about.

The End of Work?

We’ve all seen it. These processes have been facts of life ever since the Industrial Revolution began. One could argue that it all started with agriculture and domestication. We were doomed as soon as we developed language and harnessed fire. It happens over and over again. Some group of bright sparks somewhere invents processes to, save money, increase productivity, create whole new industries and destroy old ones.

Some have predicted that eventually this will result in the end of labor but, I don’t agree. What’s really happening is even scarier. It means endless retraining throughout our lives as laborers. This is scary because educational methods and pedagogy stink and are often very expensive.

Today I am a computer technician and webmaster, but it is certain I won’t be forever. I am forced to keep my rates low, because, in some cases, I compete with folks in Argentina, India or China. And you know Microsoft, Adobe, Macromedia and many others are moving mountains to make web administration as easy as word processing. I specialize in accessible web design, but eventually the production and authoring tools will get good enough to assure minimal levels of compliance without making the author think about it. The point is, I am constantly aware that my job isn’t safe and that whatever profits I make, I must save and invest, save and invest, save and invest.

So far, I’ve managed to scrape along but I still haven’t made enough to get back on health insurance. I still haven’t made enough to have money for toys and fun. I still haven’t made enough to start saving for disasters again. This I see as my fault. I really should be pushing myself harder than I am. I’ve been mucking about these last four years, more than I should have. There is no denying that I’ve learned a lot of things and done a lot of things these last four years, but I am still not disiplined enough to really work the system.

I’ll cut myself a little slack though. Ten years ago, I would have never imagined myself owning my own business. Necessity dictates invention.

Hmm. I’ve wandered far off topic. I orginally wanted to rant about automation, outsourcing and the global economy but, instead it’s become rather personal. Hmm. Well, maybe I’ll print up some business cards today.

Disaster Movies and the Electric Power Grid

So let’s assume it’s the End Times, the Wrath of Gods has descended upon us heavily in the form of flesh-eating ghouls rampaging in the streets. The question is asked, “If zombies attack, how long before the power grid fails?” Of course the question is rather silly, perhaps only for escapist horror movies, but it might have some application in development of advanced nanoweapons too. For example, suppose someone builds and seeds a plague of sleep?

SpamBayes is great!

The amount of spam I get through my business account, which is exposed to spambots, is fairly small, about 37 spam a day. The amount of spam I get through my personal account, which is hidden yet visible in a clever way, is far less, at most 6 each day. This totals to about 35 to 45 spam a day that I have to ignore. My mail traffic is small enough that I can generally deal with this through a whitelist and pattern recognition on my servers.

Recently, I’ve moved to a smarter clientside solution based on Bayesian filters. A Bayesian filter is a bit of artificial intelligence that sorts and weights patterns according to logic worked out by Thomas Bayes back in the XVIII Century.

Anyway, the plug-in I’ve got is open source, cross-platform, very accurate and will grow even more so as training time increases. Perhaps you should scope this out as well.

Cognitive Disabilites Shortchanged?

So my news aggregator captured an essay from Juicy Studios about how people with learning and cognitive disabilities got shortchanged by the WAI. After reading it, I have to say that Mr. Leitch is a little too confrontational. It is true that for some people with illiteracy, dyslexia or other learning disabilities, the Web is hard to deal with. For these people multimedia, represented by Flash objects, java applets, video clips and so on, is probably better than ordinary text and hyperlinks. And that’s one of Mr. Leitch’s points.

However I disagree with him that balancing visual disabilities with learning disabilities is always a zero-sum game. For example, improving how a site recites in a screen reader is also better for people with dylexia because that means they too can have sites read to them in a non-confusing manner. Improving accessibility doesn’t mean the categorical removal of all Flash objects. It means replacing badly designed Flash objects with ones that are fully keyboard accessible and that recite in a manner that makes sense in screen readers.

It is possible to have accessible Web design withouth pitting one type of disability against another. It is possible have improvements for one benefit another. I don’t think Mr. Leitch understands that. Juicy Studios has a followup on this issue, specifically using markup to aid information chunking

Where I stand in the political spectrum

Often I have a hard time explaining my politics to people. Or more factually, I’d rather avoid explaining my politics to people because I often find some point where I disagree with them. Or more exactly, I often find that my ideas fall apart and fail to conform with reality. Or, perhaps because I am an old fart now, I am beginning to understand why some views that I disagree with, at least initially, continue to persist.

You see, I’ve come to understand that opposing sides often have a large amount of truth. How else can it be that the right and left, after endless centuries of prosyletizing and explanation, continued to be baffled that the other side remains unconvinced. It irritates me that intellectuals on both sides of the fence think they’ve got all the answers. I guess the only thing I can really say is that Noam Chomsky oversimplifcations irritate me slightly less than George Will’s oversimplifications. I guess that makes me a Democrat. In truth what really makes me a Democrat is that I’ve been voting that way and have been attending party meetings for about 2 decades now.

Anyway, I find myself disagreeing, but often saying nothing except what I hope to be leading questions, with my friends about a lot things. I have friends who are more of a libertarian, annoyed, politically-incorrect, white (mostly they are white.) male stripe (I believe the trendy term for people of this ilk is “South Park Republicans.”) and I have friends who are more of the “anything corporations or the US foreign policy agencies, especially the military, does is unforgivably evil” stripe. I tend to fall silent or voice vague agreements when a friend of one stripe or the other begins to froth at the mouth. I force myself to remember that all of these people are intelligent and didn’t arrive at there positions without a lot of thought and experience. I know that when they froth, they are mostly right. I really can’t shoot down their positions entirely.

Yes, it is true that liberalized global trade sucks if you happen to be a worker in China or Nigeria; it pits workers in the post-industrial world against workers in the developing world. Yes, it is true that global trade is a fact and can, eventually, raise the living standards of these very same workers. See what I mean? These are both mostly true yet they are odds with one another. So I am stuck. So the controversy remains. If the answers were as simple as some make it out to be, there would be no controversy.

So I sit on the fence on a lot of these issues and take positions that would probably get me in trouble with some on one end or the other. For example, I am in favor of abortion and in favor of the death penalty. I am favor of appropriate technology and nuclear power. I am in favor of a person’s right to own a gun and in favor of regulation of gun ownership. On some issues, I am pretty clear on. I believe there should be much stronger separation of church and state than there is. Sorry but prayers in Congress and political figures saying, “god bless [fill in the blank]…” is endorsement of religion. But nearly everything else is a muddle of contradictory truths for me.

The Republicans are using the tired, old “Look! He waffles!” argument against Kerry. But, if anything, that makes me sympathize even more with Kerry. If you are really honest about the issues, you are forced to change your mind more than once. Anyone who tells you otherwise is not really paying attention and is dangerously arrogant. Yes, it is true that there are moments where things are devestatingly clear and in those moments we need leaders who are firm and unshakeable in their positions. But, on the flipside, it’s always hard to tell when fanaticism is appropriate or not.

I guess I am a political taoist. The truth is only catchable in little pieces and it’s always changing. Taoism argues that there are times for firm, unyielding hardness and order (Fanatics have their necessary place.) and there are times for vague, protean, pragmatic wafflers (Technocrats have their necessary place too.).

With that I’ve arrived precisely nowhere and everywhere. Sigh. Well, that’s where the world really is–paradox.

Still more reasons to turn javascript off!

I resolve to write one entry in this journal every day, even if it’s total crap. At least I have persisted in keeping it going for three years now; that’s a start. Chastisements are finished. Now, on to business:

Reading Mark Pilgrim’s site lead me to an explanation and a demo on how to use CSS and DOM to serve as web beacons.The method allows the server to retrive the browser’s history.

Of course it’s not really CSS itself that is to blame here; it’s the javascript. If you turn javascript off, this isn’t a problem. The sad thing is that many jugheaded or, perhaps more accurately, wiley site designers require javascript to be turned on for their sites to even function. And now that I think about it, you could use server-side scripting to make this invasion of privacy work too. sigh. Oh well. Remember to flush your history cache often, if you have anything you want to hide.

Either that or get a proxy server that blocks web beacons and hook your browser through it.

Flakey theological speculations

Let’s suppose there is an afterlife. I don’t believe there is one, but let’s just suppose there is. Why do most people automatically assume this means something? What if we die and and are reborn into a world that is just as confusing and meaningless and trivial as this one? What if we are reborn into an afterlife that brings us no closer to knowing the ultimate mysteries than we know now? The existence of an afterlife doesn’t necessary entail the existence of god or gods. It doesn’t necessarily mean anything except that there is something about physics that requires sapience to be transferred into this new existence. Is that just natural law or did the powers that be write things that way?

Just something to think about.

Accessible since 1998

It’s gratifying to see web designers getting organized about accessibility–gives me a sense of vindication. I discovered accessible web design when a friend hired me to do the Microsoft Accessibility Site back in 1997. In 1998, I discovered the work of Zeldman and the WaSP. At that point, browser support for W3C standards was poor, but I saw where the future was going. Every site I’ve built since going indy in 2000 has been accessible and standards compliant.

  • In other Webbish matters, Simon Willison has some interesting comments on the DOM.
  • I don’t have RSS or Atom feeds here but I do agree that autodiscovery is a better way of deploying such markup.
  • There is a big stink among users of Movable Type these days because of changes in the licensing of the code. I merely shake my head, being that I use Greymatter and an old, heavily tweaked version of Greymatter at that.
  • I link to these things merely for my own edification.
