More tricks for the nano bag

  • Some bright sparks at Northwestern University and Argonne National Laboratory have developed tougher tips for scanning probe microscopes. A past problem with tips in such microscopes has been that they wore down too quickly when scanning surfaces. The old process of creating new tips was very slow and expensive. This has prevented the creation of massively parallel two dimensional arrays of tips. Such arrays would have enormous benefits for nanoscale imaging and, the key thing, nanoscale fabrication.
  • Other bright sparks at the University of Massachusetts have discovered that certain species of bacteria can grow tiny conductive wires. Not only that the genetic mechanisms that produce these wires are well understood and can be altered. This leads to speculation that the critters can used as microscopic workhorses that lay down the cabling for nanoscopic circuit elements or MEMS.
  • Still other bright sparks at the University of California, Santa Barbara, have developed a nanoscopic package that can open and close on chemical command. This may be useful in delivering drugs or gene therapy in the future.

Some hobbies require a lot of work

When I know exactly what to do, I am pretty good at doing something. People have commented on how intense I am when I’m focused on something. This is odd because at the same time, I’m a lazy bastard. What I’ve found is that when I’m unsure how to do something, or if I’m unhappy with how something has turned out, I procrastinate. My perfectionism is such that I’ll spin my mental wheels uselessly searching for and examining flaws in some idea I’ve had before I’ve even tried to realize that idea. I idle and avoid that which bothering me. Sometimes this works for me in my job because occasionally a solution will come to me and suddenly everything becomes easy again. But this is a rarity. Basically the pattern is:

  • I don’t know how to do something, and can’t be bothered to learn something new, so I shut down.
  • I perversely want to get it perfect the first time so, instead of doing anything, I dither and do nothing.

Either way it leads to procrastination. In the last twenty years I’ve learned a few ways of breaking these feedback loops:

  1. Don’t try and do something all at once if you’ve never done it before. For people like me, this leads to overwhelming levels of detail and to shut down. Try to break something down in stages and practice a lot on little pieces. Don’t rush it.
  2. Don’t be afraid to ask for help. This one is especially hard for me. I have a lot of silly ego all tied up in how smart people think I am. Still don’t be afraid to ask for help.
  3. If it isn’t perfect, nine times out of ten, your standards are a lot higher than most peoples. Sometimes there something to be said for just getting something in place and tweaking it until it gets better. This relates to number one above.
  4. If the fun never comes, stop doing it. If it never gets easy, stop doing it. My friend Jeff practices on his bass constantly, almost mindlessly. If he’s bored, he picks up his bass and plug it into his amp. He’s compulsive about it and this rewards him. He can play the bass well.
  5. Anything valuable has a hurdle to climb over. The brain doesn’t do music or mathematics naturally. That’s why these things are hard. These things require practice, practice, practice. Native talent will only get you so far.

The reason why I mention this is because I have a few intricate hobbies, that, to be enjoyed, require a lot of work. They are fun but I’m always haunted with this notion that I could do a better job at them. What I’m talking about here is gamemastering role-playing game sessions. Coming up with plots is one thing but doing all the work to realize events in rules and statistics is something I’ve gone slack in over the years.

Role-playing games are my hobby and they are a lot of fun. But to a certain extent I wonder if they can also be something that can magnify other parts of my life? Maybe if I get better at doing more work before running game sessions with my friends these habits will transfer to other areas of my life?

To avoid meaningless divisions

There are a lot of beautiful and clever things you can do with CSS but, because of poor support in the browser that most people use, some of these things require that you insert DIV elements in markup that serve no purpose but to be a container that style can be applied to. The Piefecta Layout hack for example, while clever, results in markup cluttered with almost as many meaningless tags as layout tables. Many of the fancier designs at the CSS Zen Garden require the same level of div-ery. This is not what I’m looking for.

Jay has asked me to update the style of my site. He’s sick of my mild variation on FrontPage’s zero theme. I have to agree with him. Once, back in 1999 when only IE5.5 and Opera 3 supported CSS with any seriousness and Moz 1 and Mac IE5 where just fevered dreams, it was futuristic. I’ve only made slight changes to my site layout ever since. I’m long overdue for style update.

But because I don’t want to insert a bunch of meaningless markup into my pages, this limits how stunning my new design will be. Plus I don’t have the best image manipulation and generation programs in the world. Mostly I’ve been focusing on what sort background I’ll have for the masthead. I have done some research on fonts that look good and are commonly installed on most Linux boxes, so the typography shouldn’t look too shabby. I’ve decided to move to a two column layout with the content on the left and all internal navigation, save my accessibility bar, on the right. My markup is ordered so content comes first. This means I have to do a lot of positioning in CSS to make things look like they aren’t ordered that way. This another limitation which is compounded by poor support in the browser that most people use.

So I may end up with something that looks pretty bland.

So you want to pulverize the Earth, eh?

In a sort of strangelovian counterpoint to yesterday’s entry, Sam Hughes offers hard data and concrete methods of geocide. For example, we have definitive proof that gay marriage will not destroy the Earth. Supervillians take note!

EARTH-DESTRUCTION ALERT LEVEL: Current Earth-Destruction Status
Be assured that we, here at Farlops Industries, will keep you informed if this status changes.

In case we forget

Today is the sixtieth anniversary of the use of nuclear weapons on Japan in World War II. Rather than go into the justification or lack of justification for those events, I’d rather point to the fact that there are still about 20,000 of these weapons in the world today. And just remind us how horrifying these weapons are, Eric Meyer has built a tool that maps the effects of a one megatonne ground detonation over Seattle.

Fashion modeling and athletics are doomed

We pay some people very good money because their bodies have certain talents in running around in a field chasing a ball or jumping through hoops or some such nonsense. We pay others very good money simply because certain aspects of their phenotype make us look longer at adverts then we’d otherwise would.

But I have seen the future and it doesn’t look good for people who make their living this way. Technology will bring a democratization of talent.

People are already trying to improve or retain their appearance by surgery and other medical techniques. The end result of improvements in these technology is that people will be able to buy themselves whatever physical appearance they think looks good. But even before then, the writing is already on the wall for people who make their living off their phenotype.

Computer graphics may have doomed fashion modeling. All they have to do now is snap a few images of a model’s face and hairstyle and then mount it on a wire-frame surfaced with the latest designs from the fashion houses, do a little editing and–bang–a still image that looks are real as necessary to sell us a product. They may not even have to do that. Artists can just walk out in the street and look at what the kids think is pretty or cool and then go home and render on the screen a human face that captures that look. This face, which belongs to no real person thus avoiding copyright issues, can then digitally pasted into any background necessary to sell us junk. This is already possible, at least for still images.

The Uncanny Valley may slow down this in motion clips but not for long. It’s only matter of time when the runway will be entirely virtual. If you’re a model, now’s the time to register your face as property.

Athletes are ultimately race cars or high performance aircraft. I know a lot of people will disagree with this but, let me explain why. With each new drug scandal in the Olympics, it becomes obvious: bodies can be built to order. Physical talent and ability can be made.

In team sports all that really matters is the intellectual aspect: the strategies of the coaches and the tactical surprises by players. The day may come when the brains of athletes are swapped between various bodies as the old ones wear out or need repairs. Training will only be needed for getting the brain used to the idiosyncrasies of the new body. I know this is a boggling idea but I think that’s where it’s headed.

Today we watch software games as a spectator sport on the cable networks. We already have robot demolition derbies. Tomorrow, athletic equipment companies will be selling bodies to the teams and players that can afford them.

Of course people will still pay to attend the games of amateur athletes–the games of the less physically gifted, but in professional athletics the demand for the best talent will reduce it all to biomechanics in the end. Aside from the strategy and tactics, that’s what it is in the end.

He's a pinball wizard

So there’s this 17 year old kid who kicks bottom and takes names when playing Mortal Kombat, Soul Caliber and other games at meets and on the Network. The thing is he’s been blind from birth.

The Long Downward Spiral of the Space Shuttle

Let's face it. With each passing year, the Space Shuttle grows more and more pathetic. Bold promises for human spaceflight continue to ring hollow.

Robots will always be cheaper and do more science. SpaceShipOne is just a joyride–and no, that's not just sour grapes over the ticket price–four or five minutes in freefall is simply not a useful engineering accomplishment. Colonizing is really the only reason
for humans in space
. Aside from supporting good international relations, and keeping Russian scientists and engineers employed and destracted from building missles for the highest bidder, the International Space Station has no serious mission.

The point is that none of these things has any long term reason for being. But you've all heard me gripe about this stuff before. So what's my constructive alternative?

The world's space agencies (ESA, IPNE, RKA, NASA, NASDA, CNSA, ISRO and anyone else who is willing to spend a few billion dollars.) should band together and build a few space elevators.

Only if they do this will I take human spaceflight seriously again. Interesting article in Spectrum about the space elevator.

Well–at least it's about movies.

The B-Movie Comic was recommended to me by the folks of the In Sect. B-Movie is pretty funny! Imagine archeologists, dodering professors, plucky Chinese orphans, goths, a doomed family of Egyptians, jocks and ancient priestly mummies wearing t-shirts all suffering at the hands of bad continuity and low budgets in a cheap horror movie.

Internet Explorer 7, First Beta

Well, everyone else is talking about it and, me being a webmaster, I really should say something but, I really don’t have much because I’m not a MSDN subscriber so, I can’t get a legal copy. Today, I’ve been reading reviews on sites of designers and developers whom I respect and the consensus is that the first beta of IE7 is disappointing. It’s looking pretty clear that programmers at the Lazy M Ranch have really only been at it since a year ago when they finally got scared of Mozilla.

This leads me to a design decision. When IE7 rolls out for XP and Vista, I’m going to install stylesheet hiding tricks on all the sites I maintain and drop presentational support for all releases of Internet Explorer before version six. This will help me maintain sanity.
