  1. Re:clearly on Americans Less Healthy, But Outlive Brits · · Score: 1

    What isn't included in this survey, I surmise, is that the sick Americans are kept "alive" longer, by bankrupting them on expensive medical technologies and pharmaceuticals. It is a life-extending technology that only kicks-in, once the damage has been done!

    I think it's more likely that the metric used to measure health is a poor predictor of life expectancy. In fact, the article actually demonstrates as much. This could be because, say, the ability to run a few miles or the number of days spent with a cold each year might indicate good health, but doesn't mean you won't come down with a bad case of cancer or something else that may actually kill you. I suspect Americans are in worse overall health because they're less active and more overweight, wheras brits consume a whole lot more alcohol.

  2. Tradeoffs on In Praise of Procrastination · · Score: 3, Insightful

    I think most people would happily trade 10% of their salary for 10% more vacation (5 more weeks). We in the U.S. work way too much and live too little.

    As for procrastination, unfortunately it often pays off in the workplace. If your boss asks for something to be done at deadline D and you know it takes T, then you do the prep work up front (like research the problem) but don't actually start on the specifics until D-T. Because quite often it turns out no longer to be needed, or before T arrives it's discovered something different is needed, so different that you would have to start over on the task-specific parts. Personally I hate having work on my plate and compulsively finish it up as soon as possible, but doing so isn't really in my own interest (in terms of ROI on my work).

    And, like always, laziness is the mother of all invention. We harnessed animals so we wouldn't have to work ourselves, invented mills to save work of hand milling, etc etc. Basically we invent machines and smarter ways of doing things to save work. Unfortunately this is contradictory to the modern workplace where if you created a machine to do your work for you the employer would lay you off rather than continue paying you a salary for work done by your machine. More specifically, they'd buy your machine and RIF those now superfluous. It's why sysadmins automate tasks with scripts, even though if they do it well enough they might soon find themselves without work. Similarly an engineer who does the work of two and consistently delivers quality results early, without even appearing to work hard, may find management suspicious of whether their job warrants even one single full-time position. At least if management isn't technical enough to tell the difference.

    The best materials we currently have to make plastic solar-cells ("organic photo-voltaics") have pretty poor efficiency.

    But if it's a transparent film, even in the absorption spectrum, you could stack it several layers deep and possibly give each layer a slightly different absorption spectrum. Behind the stack you sandwich a mirror so residual light reflects out for a second trip. Maybe the mirror or a top film could be made to fluoresce as well to bring more energy into the absorption spectrum.

    A Mac Mini can do many things just fine. I know a place that uses a Mac Mini to manage four Epson 10800 printers and a Lightjet. It runs three different RIP servers. It clones itself to an external drive daily and backs itself up with TM to the same drive. If it were to go belly up (and it probably will, eventually) they replace it with another, boot it off the external drive and restore the last 24 hours, or most of it, from the TM incrementals. While it runs they can clone it back to the internal drive. It has no display but is entirely managed using screen sharing. If the Mac Mini supported target disk mode they could get rid of the external drive entirely and just keep the spare as a bootable backup in TD mode.

Concepts like rates and rates of rates, and their inverse accumulations, are pretty easy to understand and conceptualize, in that to many if not virtually all people they're intuitive, which makes them perfect for an introduction to abstract thinking. It implicitly teaches students to model the world, in ways that can be formally proven to be as correct as the underlying assumptions, with results whose accuracy only depend the accuracy of measurements. It implicitly teaches notions like time-shift invariance (meaning it works a way today it works the same tomorrow). Even if this is ALL they take away from it, at least they develop the notion that reality can be modeled. What if they weren't exposed to the concept at all, ever? They'd be intellectually much, much weaker. Calculus plants an embryo of scientific thinking. It's hard to learn for most people because they're not used to thinking abstractly.

It's just something they got as part of the deal.

    Too many different settings and options, spread over too many different places - fairly typical implementation-driven UI design (rather than UI design-driven implementation). The feed itself is pretty good, though made overly complicated sometimes - for instance, why is there a separate 'latest"? basically it seems to be some sort of manual cache refresh, and why would it think I want anything other than the latest?! What is "not latest"? The supporting facilities, like photo albums, are also pretty messy - people typically just want to "post photos on facebook", not manage albums and slide shows or whatever.

    Apple is very good at designing these sort of things, especially with regards to integration. They also don't shy away from doing more complex engineering work to support a simplified interface with fewer settings.
