  1. Re:One possible argument for lunar industrializati on Giant Magellan Telescope Set To Revolutionize Ground-Based Astronomy · · Score: 1

    As careysub already posted with a different link, no, it doesn't. In fact, it appears to rise up and coat things that are left on the lunar surface, darkening them.

    One of the source articles for the Wikipedia entry above talks about this in more detail, but also points out that lunar soil appears to sinter really, really easily when microwaved. It seems like this could be an effective and (via plentiful electricity from sunlight) economical way to "dust-proof" limited regions of the lunar surface. That, coupled with a fairly simple static-charged chicken-wire fence to divert or intercept laterally-propelled dust, might well make the problem manageable.

    That's... amazing. Color me incredibly jealous.

    I'd guess they were throwing away nearly all that aperture -- to get all the scope's light through a 4mm exit pupil, you'd need close to 2000x magnification, which would make the nebula look like it was about 24 degrees across -- okay, that would fit perfectly into a normal field of view.

    So, yeah. I hate you even more.

    (Wonder what kind of 4mm lens could successfully catch all the light from a system that size? It's been a long, long time since I was immersed in the amateur-telescope-maker literature...)

  5. One possible argument for lunar industrialization on Giant Magellan Telescope Set To Revolutionize Ground-Based Astronomy · · Score: 3, Insightful

    It seems like the Moon's surface could be a fantastic place for an absurdly large optical telescope. No significant atmosphere, little or no vibration, low gravity (making for less distortion of the optics), and plentiful raw materials for making fused silica and aluminum surfaces.

    Obvious drawbacks: not a good place for humans, a two-week period of daylight (not necessarily a deal-breaker without an atmosphere, but a source of thermal stress), and a REALLY BIG dust problem.

    You want stereo vision but you also need the focal plane to change as the eye changes focus.

    Fortunately, there's a cheap and easy solution to this: age. By the time you're 50, it's extremely unlikely that you'll have enough focal accommodation to matter.

    This means I'd be totally ready for VR, if not for my extreme susceptibility to lag-induced motion sickness.

  9. Probably a result of dev/designer demographics... on Amazon's Thin Helvetica Syndrome: Font Anorexia vs. Kindle Readability (teleread.com) · · Score: 4, Insightful

    I think we all see that there's a big push toward The New Shiny for implementing Web UIs, and a push toward hiring young frontier-chasers in place of older developers and designers who are perhaps more attached to older, less cutting-edge technologies.

    Well, surprise -- younger people IN GENERAL have an easier time focusing on close targets, perceiving low-contrast images, and dealing with generally lower light levels.

    Now, most of the designers I've worked with at least pay lip service to accessibility, universal design, and maybe even special-needs users. But when they're showing mockups to decision-makers, they still seem to push for what's trendy -- and, hey, the twenty- and thirty-somethings in the room have no trouble reading it, and if the forty- and fifty-somethings do, they sure aren't going to call further attention to their "differently youthful" status by complaining about it.

    As a result, we see today's visual design. If we squint enough.

    Of course it's perfectly safe for me to speed. The speed limit is set for the lowest common denominator. If I drive a car with a sports tuned suspension, and racing is one of my hobbies, then the speed limits as set are significantly slower than what is safe for me.

    Ah, another proud member of the 93% of US drivers who consider themselves better than average, I presume.

    At the risk of being branded a "but think of the CHILDREN" weenie, I feel compelled to point out that your safety is not the sole consideration when you're driving through a residential area, like the one in this story.

  15. Yep, eBay knows, and doesn't care. on Severe and Unpatched eBay Vulnerability Allows Attackers To Distribute Malware · · Score: 4, Informative

    eBay has been open to JavaScript exploits for well over a decade. When I first realized this, I tried to make a fuss about it, but was met with uniform yawns and dismissal; the post or two that I made about it on eBay's discussion forums was summarily deleted.

    If they had been trying to allow a limited subset of JS code in listings, I still would've been alarmed, because I would bet against their ability to define a safe subset, never mind successfully blocking anything else. But it looked to me at the time like they weren't doing any blocking at all. I don't remember exactly what I did in my test listing; it might have been triggering one of their buttons (like Buy It Now) from a button in my description, or it might have been attaching a new action to one of their existing buttons. It looked like I could also have (say) rewritten the price field, so that it looked like you'd be paying one amount but actually get charged a higher amount. I didn't even start trying to generate overlays that look like eBay controls but actually did my bidding, but it looked like the opportunities were practically unlimited. I didn't push hard, and I deleted the listing before anyone else could view it, because I was doing a fair amount of business there at the time, and I didn't want to be the messenger that got shot.

    I just can't imagine what they're thinking by letting people embed arbitrary JS in listings. I'm stunned that there hasn't been a catastrophic exploit in all this time. I've assumed that I was simply overlooking some critical piece that they've implemented to guarantee security, but this story doesn't exactly instill confidence.

    As for being effected -- no, I'm pretty sure I was effected by much more down-to-earth influences. Okay, maybe strong tides were a necessary condition for life to arise on Earth, so perhaps we were "effected" by the Moon's gravity, too. But not magnetism.

If not, I stand a really good chance of successfully repairing it myself, unlike most electronics released in the last couple of decades.
