Buses seemed to me to be a rare case where they are so big and heavy anyway, that low energy density from a cheap and old-fashioned lead acid battery could still work. But you're right, I started searching, and found a 2005 US DOT anal

Air quality indices, at least measured in PM2.5 or PM10, seem to be closer to 200-600 for the overwhelming majority of places in Shandong (which I assume is what you meant), currently and for the past 48 hours. I could only find one place [

I wonder if the financial incentives (i.e. bribes) to avoid China also stipulate buying Cisco or Motorola. If not, I wonder if this will backfire and create a great opportunity for Fujitsu/Ericsson/Nokia to advertise their relativ

If a tree falls in a forest and nobody is around to hear it, PE funds would love for you to believe it doesn't make a sound! That said, besides the lack of real time mark to market reporting and thus lack of measurable volatility, perh

Indeed I've been doored and have had numerous close calls. What got me the first time was a false sense of security from the bike lane painted right alongside street-side parking spaces. With roads that narrow, people may actually be s

https://news.ycombinator.com/item?id=8561326 Similar discussion from about 2 years earlier. I think that we react and reflect similarly is a good thing, though I've no clue how conditions changed overall in this time.

Reminds me of a system Nintendo endorsed in the 90s using satellite radio as a subscription for games and related broadcasts. I'm surprised such a niche like add-on gained so much traction to last 5 years! https://en.wikiped

There are business implications too -- I remember an article years ago about Unilever or some similar company's ambitions to enter a virtually untapped Chinese deodorant market. I just tried to find what happened, and it seems that did

This looks amazing. If a scanned PDF is OCR'd and the lines still as raster images, could extraction through Camelot work? Another serious question -- if I use this successfully, does that make me King Arthur?

And most are helpfully marked for unit conversions as well! I have mine set for restaurant tipping by default (North America).

It's precisely the fear of having navigation turned off that led to nations launching their own GPS alternatives. More satellites is better for critical transportation if one nation (be it China or US) wants to turn disable their syste

From my armchair--it could be somewhere in between what's considered purchasing power parity and the actual exchange rate, because goods aren't exactly comparable when the entire supply chain is less advanced. You may pay less for

I was thinking the same thing! I would pay serious money for this sort of thing in a kit. Maybe in general, that's an opportunity for something like Shapeways, but for laser cutting/milling. Edit: ponoko.com

Is it odd that the IRS is mandated to publish the full names of all who renounce US citizenship? Not that names are necessarily private information, but most other times when government agencies publish names, it's a wanted persons lis

Use a non-Chinese carrier if possible (if you are from the US, Project Fi, or the T-Mobile plan with unlimited international roaming come to mind). You get a built-in tunnel to the home country and full access to the internet that way. Lots

Consider literal competitions--it was similarly appalling to watch recent Olympics in the US. 95% or more of the coverage was of Americans winning. If a particular day had fewer wins, they would replay earlier footage rather than dare show

Jokes aside, I think that's exactly it. Mathematicians aren't tempted in the way that others may be in connecting what they do to humanity. Not being in it to cure a disease, build a better mousetrap, or create a triumphant explan

Agree--there's a sweet spot in distance and terrain as well. I bike to work every day because the round trip is a smooth 6 miles on dedicated bike paths. If this were any longer, or on the city streets with traffic lights every block,

Unrelated to calculus, a simple mental trick for quickly calculating squares close to round numbers is to just break it into (a+b)^2=a^2+2ab+b^2. E.g. 51^2 = 2500+100+1=2601.

I've got mixed feelings returning from Japan. My best and worst stays were both AirBnB's. The best, which is still listed, came from a host who owned the place and very thoughtfully went out of her way to share local things to do.
