    The only way to validate the model is to apply it and see if it works. The problem with hish risk disasters is that they don't happen all that often so it's hard to validate the model. I mean sure you can special case it to death to get it to predict "the Columbia disaster, Hurricane Katrina and the World Trade Center collapse" but if you special case it too much it loses predictive ability for similar but not identical events.

    True, but, despite the /. summary, the article really isn't about predicting events so much as trying to assess the level of uncertainty around the results o fteh model. By quantifying the uncertainty you can better use the results to decide what to do. Essentially, you want to be able to say "I think this will be the outcome, but I am only so sure about the accuracy of my prediction." It's not really about predicting the future (in the sense of "what event will occur" but what will happen if x occurs and how certain am I about that result.

    Yeah, I hate to go all Taleb but that doesn't make sense from a Black Swan point of view. The catastrophes outside the model are always the worst catastrophes because they are outside the model.

    True, but they aren't trying to predict Black Swan events, at least not from my RTF. Take Columbia, for example. If, after running the damage model, that had said "there is only a 20% chance we are right - i.e. there is a high degree of uncertainty surrounding our results" then NASA would have known to further analyze the situation. They weren't trying to say "there is x% chance a shuttle will suffer damage on launch the results in catastrophic failure of the vehicle on reentry."

    By being more certain about the uncertainty you can better use the model's results to make decisions. You can also the better use the model to try to estimate the outcomes of rare events - such as what might happen if we experience a Cat 5 hurricane, how much time do we have if we wipe out the backup diesels, etc. You can't say what are the chances of the initiating event but should be able to better assess the likelihood of the outcomes.

    Like the OP, I am self-taught, and am of the same mind as CmdrPony, having done it myself. If you need to start working right away...

    Start your own shop, but count on the website/SEO/marketing side of things to start slow and develop (no pun intended) over time - likely several years. The market for "website developers" is fairly well saturated, albeit with far too many that are no more than Dreamweaver/FrontPage/MSWord-using ex-construction worker/secretary types who are 95% clueless yet able to put up a $200 site in a few days by advertising on Craigslist. Yes, your site may be far better, but money talks, and many clients don't understand the finer points of what makes a really good, nice-looking, fast rendering, cross platform website, or what SEO is and the kind of time it can eat.

    The problem you have is you're always competing with the $200 folks - at least in the customer's mind. Unless you can build up repeat business maintaining a site you'll face the "So and So will do it for $XXX." Until you get a good book of references it's hard to overcome the price shopping; and most small businesses you'll target are very price sensitive.

    Until you have a solid core of client sites showing your skill and capability and helping you sell at a price point that makes it worthwhile, your working capital and day-to-day income can be supplanted by the other computer skills you have: repair, networking, etc... Be willing to make on-site visits (even to homes - at least until you get too busy), and have a fast response time. Come up with good ways to describe common computer problems and your fixes for them in normal human-speak - people do like to understand a bit about what you are doing, and teaching them a little helps them become better users and clients.

    I'd add in - be willing to change your business model. You may find fast in house support is more valuable than web design - if so, go with that. Offer web design on the side - as one more service offering. Also - offer to help select products - by providing impartial third party advice - for afloat fee - you may be able to build a business there; but be aware people will expect "free" support - make it clear what they are buying.

    Find a small, cheap location where you can set up half a dozen systems while you work on them, get some biz cards made, and put out your shingle.

    Be very careful about renting space - that is a cash flow problem you can't easily make go away; unlike working form home via cell phone.

    If you did any of your own darkroom work back in the wet film days, then you remember making careful adjustments to the enlarger, deciding just which paper to use, and giving due consideration to how long to leave the paper in the developer bath before the fix. And so on.

    Far to well. You can still chose papers in today' s digital age.

    But either you or a machine was doing the post-processing that we now can do so much better in today's software. You should really look into what Gimp can do for you with its unsharp mask (the digital equivalent of focusing the enlarger), and its HSV settings (equivalent to choosing different papers and development timings). Not to mention using masks to process different parts of the image differently, and do not get me started on the wonder of layers.

    The photo that comes straight out of the camera is an unfinished work. It might be adequate for some purposes, but it is never as good as it could be.

    Some of your comments made me interpret your point as "don't worry about such things as composition, lighting, etc. since you can fix all of that in post-processing." While I agree with you that post-processing is part of the overall process; it's not a substitute for creating a good image when pressing the shutter. Understanding composition, lighting, DOF and other fundamentals are as, if not more, important than post processing. Today's digital systems makes it to easy to gun off a bunch of images in hopes of getting one good one or leaving you to try to fix it in photoshop; when a little bit of skill at the start would result in a far better picture.

    I'm not a big GIMP fan; the Mac has a number of inexpensive products that have a much better interface than the GIMP, IMHO. Layers and curves are cool; but for minor tweaks, not wholesale fixes of bad images.

    The photo that comes straight out of the camera is an unfinished work. It might be adequate for some purposes, but it is never as good as it could be.

    Sure, just as a selective light dodge or burn, or getting the right paper and exposure in the dark room, helps a film image; digital post-processing helps a digital image (without the need to mix chemicals). We're probably in closer agreement than this exchange would indicate; if I misunderstand your position mea culpa.

    A decent photo is one that can you work with in Photoshop (or the Gimp, which is better for everything except a few types of professional work). The kinds of things you want to be able to do are cropping and rescaling, selective blurring of background distractions, selective sharpening with the "unsharp" capability, often some tweaking of colors. In this day and age, a photo is not finished until it has been photoshopped at least a little bit.

    I disagree here - if you have to do all of that to get a great picture you really need to work on composition and exposure on the front end. True, photoshop can fix some errors or improve a picture; especially with good cropping, but nothing beats getting it right at the moment of exposure.

    I may be old school because I started out with film, where you were forced to setup the equipment and shot right at the start; and you learned basic rules of thumb for exposure, depth of field, composition because fixing things in the darkroom was hard and time consuming. End the end, however, you developed an instinct for what was needed at the moment you pushed the shutter button; something the run and gn and photoshop later crowd is missing out on, IMHO.

    2) take lots of pictures. if you get a one good picture out of 20-36 exposures, you're doing well.

    Your advice is good - although I'd add a few comments:

    1. Digital cameras have made it easy to shoot hundreds of pictures in hopes of getting one good one. The problem with that is people never learn composition, lighting, etc. - things film forced you to consider due to cost and limited exposures per roll. Sure - take lots of pictures but read up on the basics of exposure and composition - learn the rule of thirds. light zones, etc. Experiment with different settings - aperture, shutter speed to see what happens. Look at photos and decide what you like about them. Learn to look behind the subject - 30 photos with a branch growing out of someone's ear doesn't do you much good. Ultimately, it's the brain behind the lens that makes the difference.

    2. The biggest advantage you get from a dSLR is depth of field - but it's not worth it if you leave your camera at home. I have a number of dSLRs and a bevy of lenses; but 80% of the time it's a 5 year old Canon point and shot that I have on me, simply because fit early fits in a pocket or briefcase.

    3. Consider a ruggedized point and shot - one that you can take to the beach or in a pool. Buy extra batteries. Buy several smaller memory cards instead of one really large one. You can swap them out and if one dies you don't lose everything.

    4. Don't get caught in the hype over megapixels or zoom length. Every name brand point and shot today has a good quality sensor and lens that will work just fine for a hobbyist photographer.As with any hobby, some people spend more time measurabating over specifications than actually enjoying the hobby.

    5. Visit some photography web sites. I like Fred Miranda's site (fredmiranda.com) - posters will give good advice and critiques of your work, no flaming or gear wars; just a group of people interested in photography.
