  1. Re:Stop burning fossil fuels on Brainstorming Ways To Protect NYC From Real Storms · · Score: 2

    Decades ago we "knew" that civilization was causing a new ice age.

    Maybe a few people "knew" that. But the concensus among scientists was otherwise.

    I grew up in the 50's and 60's in the Seattle area, and one thing that was mentioned there is discussions of the topic was that in the Pacific Northwest (roughly British Columbia south to Oregon), the glaciers in the Cascades had been growing for most of the century. This was generally recognized as an anomaly, since nearly everywhere else in the world, the data showed an overall slow warming trend. At the time, none of this was explained, though the general warming was usually attributed in part to human activity.

    Since then, we've learned a lot more about climate. Well, scientists have; most of the rest of the world hasn't learned much at all. And the cooling in the Pacific Northwest has ended. I visited there last year, for the first time in about 30 years, and one of the shocks was seeing the iconic Mount Rainier, whose glaciers are much smaller than what they were back around 1970. I also visited the mountain, including Sunrise, which used to be a short trek to the nearest glacier. Now the glaciers are miles away, and there are sizable trees growing around the lodge. This really got the idea across that things were changing.

    Of course, if it were just that one area, it wouldn't mean much. But it's the same story in most of the world now. And this wasn't a surprise. It was what climate scientists were describing back then. They just didn't predict that the change would be so fast.

    But they are having fun studying and explaining it. The large population with economic and/or religious reasons not to believe it are a bit annoying, but this isn't anything new. The powers that be have never paid any attention to suggestions that they might be doing something with long-term detrimental consequences, even when those consequences are staring them in the face.

    Tokyo is sheltered from the sea in an inlet. NYC sticks right out into the Atlantic seaboard. What they do in Tokyo won't work in NYC.

    Oh, I dunno about that. I have two Google Maps windows on my screen right now, one of the New York area, the other of the Tokyo area, at the same scale. True, the details are different, but overall they don't seem to be very different in their exposure to the nearby oceans.

    If anything, it looks like New York is better protected, especially Manhattan Island. It's at the north end of the 8-mile-lond Upper Bay, which has a rather narrow (~1 mile) opening into the Lower Bay, which in turn has a couple of barrier islands and a lot of continental shelf between Manhattan and the deep ocean.

    Tokyo is on the much larger Tokyo Bay, which is rather serpentine, and connected to the Inland Sea by the Uraga channel, around 6 miles wide. But the city area is near the eastern end of the Inland Sea, with no significant continental shelf. So if anything, Tokyo is more exposed, by the closeness of the open ocean and deep water, with wider channels to the central city area.

    But overall, they don't look all that different. And Tokyo has the extra problem of being in an active volcanic zone, while New York's geological underpinnings are much older and stabler.

    I'd guess that, all things considered, New York's geological, hydrographic and meteorological environment is somewhat safer than Tokyo's, though probably not by much. The general cost of protecting them isn't really all that different.

    The difference is that the Japanese are well aware of the dangers inherent in their natural environment, while New Yorkers are either oblivious or arrogantly sure that God/Nature/whatever is on their side. The Japanese weren't all that surprised by the recent epic earthquake and tsunami. New Yorkers seem surprised and offended that the natural world could do something catastrophic to them.

    Before the 1960 election, lots of pundits said he couldn't win, because there were millions of Americans who would never vote for a Catholic. After he won, investigations turned up the explanation that there were in fact millions of voters who would never vote for a Catholic, but they were also people who would also never vote for a Democrat. So his being a Catholic didn't actually lose him any votes.

    The same explanation has been proposed for Obama's wins. For those who can't figure it out, the explanation is: Yes, there are millions of Americans who would never vote for a black man (or woman). But they are mostly people who would also never vote for a Democrat. So being a black candidate running as a Democrat doesn't lose you hardly any votes.

    A few years back, I experimented with a lot of editors (and terminal emulators), when I got seriously involved in i18n (internationalization) efforts. I was at that time unable to find any editor that handled UTF-8 encoding as sanely as vim, so I've stuck with that. It'd be interesting to know if there are other editors that do a good job with mixed writing systems these days. Others have to have worked on it, but I haven't found time to repeat my investigations (which were a really frustrating time sink).

    I also tested out a lot of terminal emulators. I'd long preferred xterm, because of all its nice features (except for its confused, inconsistent command line args ;-), but I gave up on it when I found myself dealing with some documents that mixed English, Chinese and Arabic writing. I found that xterm could do Chinese in only a few font sizes, and Arabic in only a few font sizes -- and the lists didn't overlap. Also, xterm sometimes insisted on showing Arabic and Hebrew text left-to-right. I couldn't find a font size that would correctly display a page with both Chinese and Arabic text. Of course, most others couldn't handle one or the other of these alone, and most were really crappy for right-to-left writing. But the linux and apple "Terminal" terminal emulators could both handle the job, so I've been using those.

    I'm still looking for a way to remotely edit such mixed-writing docs remotely over an ssh link, without it occasionally going insane and forcing me to do a "kill -9" on the terminal process to recover. Again, the linux and apple terminals seem to do the best job of this, but they both sometimes go insane for no obvious reason; killing them and repeating the operations in a new terminal window usually "fixes" the problem.

    It's been a couple of decades now since Ken solved our charset problems. Why is it taking so long to produce versions of things like editors and text display "terminal" windows that do it right?

    Maybe moving to a "browser as OS" approach is what is needed. This also seems insane, but if the rest of the software world continues to show such contempt for languages other than those that the author(s) speak/read/write, maybe we don't have much choice.

    Still, locally I find that vim does a fairly good job with mixed-writing documents. The main problem seems to be the awkwardness of switching between keyboards for non-Latin writing, and the need for ASCII chars for vim commands. If someone has solved this problem, it'd be interesting to read about.

  10. Re:complain on Google Doubts Apple Will Approve Its New Maps Application · · Score: 5, Informative

    So basically Google wanted to ... add a feature which let Google keep track of where every iOS user is. I can understand why Apple wants to make their own maps in the long run.

    Actually, Google's map apps have had this "tracking" for years, and they've been very open about it. We've discussed the fact here before. This tracking is the basis of the Google traffic reports. The folks at Google have explained from the start that this feature gets its traffic info primarily from the cell phones running Google map apps, which uses the GPS data not only to show you where you are on the map, but to report to their traffic-control database where your phone is and how fast it's moving. This info is summarized, and sent to the other phones' mapping software to color the roads green, yellow or red. (And you can turn off this "tracking" by exiting the Maps program. ;-)

    One of their frustrations right at the start was that, although the Google Maps app was on the iPhones, for several years Apple blocked this "tracking", so iPhones were in effect leeching off the Google (Android) traffic info without contributing to it. Eventually Apple relented, and allowed the iPhone population to add to the traffic info, significantly improving the coverage and accuracy of the data.

    This is a nice example of a "social good". The best traffic reporting system would obviously collect data from all moving GPS gadgets and make it available to all such gadgets. If individual vendors create "walled gardens" and only allow their gadgetry to communicate with their traffic system, then we get a flock of partial-coverage, low-quality traffic reports.

    Apple has once again chosen to take this route, by splitting off from the (currently) best such system. If they had our interests at heart, they'd instead be pushing for a common traffic-reporting database shared and supported by all the vendors. Google's approach here could be described as pushing for such a shared, public database, though their holding part of the API private is an example of them trying to limit the capabilities of competitors.

    Thus, Google isn't acting entirely in the public interest here. But they're a lot closer to it than Apple, who are clearly pushing for the "walled garden" approach, to the detriment of everyone except their shareholders. In contrast, Google does make their map API available to the public, no matter which gadget you're using.

    If the "public" had any sense, we'd be demanding that these companies pool their traffic-reporting resources into a single publicly-accessible system. But the public (at least here in the US ;-) clearly has no sense at all in this matter.

    If you like hot peppers, they're an excellent crop for anyone with a sunny window. Some of the tastiest are sold as "decorative" peppers. This term doesn't mean that they're not worth eating; it comes from the fact that peppers like full sun, but many good hot peppers are from small plants that get shaded out in a garden by other, bigger plants. So you grow them in pots that can be put on any sunny level spot, like a porch or patio or window sill. When they get covered with flowers plus green, white, orange, purple and red fruit, they're very decorative. Like sweet peppers, they're edible at any color stage, though the ripest tend to be the hottest. The green or white ones are less hot, but this lets the other non-hot pepper flavors come through.

    One problem in our household is that, due to my wife's allergies to most furry critters, we share the house with three small parrots. Like most birds, they love hot peppers, and strip them off the plants when we're not watching. So when we take the peppers indoors for the winter, we have to put them in a few sunny windows that the birds can't easily access.

    Like tomatoes, peppers like rich soil and lots of water. So give them some compost if you can, don't let them dry out, and you'll have some very pretty, edible crops in a few months. You can use the seeds in any hot pepper that you like, but if you use a store-bought pepper's seeds, you'll have no idea how big the plant will be. So it's better to just ask for a few peppers from someone who's already growing them. Just plant a few of the seeds in each pot, put them in a sunny spot, and keep them watered.

    Well, maybe so, but there's another problem that nobody seems to have faced. Most of those asteroids are rotating, and they all have surfaces that are irregular at every scale. Unless you have very precise topo maps of the asteroid, down to the sub-millimeter scale, you won't be able to precisely calculae the direction of thrust of the paint splotches. And once a splotch is there, if its position is off by even a few cm, it's likely to produce a thrust in a different direction than you wanted.

    A rocket that lands and produces thrust would at least be controllable by turning it on and off at different point in the rock's rotation. That's a lot more control than you could get with paint splotches.

    If you want to use light pressure, I'd think you'd be far better off going with a flock of little light sails, which would land scattered over the asteroid's surface. Then you could send commands to precisely control which of the little sails are reflecting sunlight, and you'd actually be able to (slowly) make changes in the asteroid's orbit. That would probably be a lot more effective than paintballs or rocket motors.
