Comment Re:Better definition of planet (Score 0) 196

And it is a planet. It's a dwarf planet. Dwarf means small. Planet means planet. Dwarf planet means small planet. So what's the problem?

How many exoplanets pass the current IAU definition of 'planet'? I bet a bunch don't.

Of the ones identified thusfar? I'd wager "the vast majority if not literally 100%". We can't see little stuff. Everything we see is big, which means strong orbit-clearing power. And usually also close to its star, which also helps clear the orbit.

Exactly. There are many categories of planets, including but not limited to:

  * Terrestrial planets
  * Gas giants
  * Ice giants
  * Hot jupiters
  * Superearths

And so forth. Why does the concept of another category, dwarfs, enrage people?

Really, the only categorization issue that I'm adamant about is that Pluto-Charon is called a binary. The Pluto-Charon barycentre is not inside Pluto, therefore Charon is not rotating around Pluto, the two are corotating around a common point of space between them. That's a binary.

Now will ICANN put its foot down

It had better hope so, because giving entire TLDs to specific big companies could easily be the straw that breaks the camel's back in terms of the rest of the world accepting US-led administration of the general Internet. There's plenty of scepticism already, but organisations like ICANN are tolerated because frankly no-one has much of a better idea or wants to take on the responsibility. However, it is not difficult to think of a better idea than letting big businesses rewrite the established rules in arguably the most important address space in the world today for their own benefit.

Comment Multiple whiteboards + Google Hangout (Score 4, Interesting) 164

Okay, so the submitter asked for "good" solutions, and this may not qualify, but it's what I do: A whiteboard at each location, with a camera pointed at it. I can't draw on your drawing, but I can see what you draw, and you can see what I draw. I've experimented with various web-based shared whiteboards, but they all require drawing on the computer. Even with a tablet (either Wacom-style attached to a laptop/PC or a mobile device) and a pen, a real whiteboard is better.

In my case, generally there are at most three locations in the meeting, and usually only two: My home office and a group of people in a conference room. Having more may make the "real whiteboards" solution less effective.

Well, then that's their limitation, not mine. I am tired of this trend of dumbing things down to the lowest possible.

Damn straight. It's like all these stupid GUI interfaces. I mean, I can see using a graphical interface if you're editing photos or something, but for reading and writing text? It's ridiculous and just makes it so that stupid people can do it without having to understand anything.

It all started with visual text editors, you know? Line editing was good enough, heck, you could argue that it made things too easy, too. What was really good was when we used toggle switches to enter data and read the output from a sequence of lights. If you can't mentally translate binary to ASCII you don't deserve the power of computation.

Right on. It annoys me when I see people using google search to go to a specific website, rather than use the address bar to go there directly. If you try to explain to them that the address bar will take them there without having to click the first search result, it's like they don't even want to know.

I think this is just a further extension of the location bar vs search bar change.

I remember when I first saw the Chrome omnibox. It offended me. Mildly, but still. I know the difference between a search and a URL, and I am perfectly capable of clicking into the correct bar. Then I actually used the omnibox for a while (because Chrome was so blindingly fast compared to other browsers at the time) and found that when I jumped back to Firefox I got annoyed at the mental effort required to use the split location/search fields, even though it was trivial.

The fact is that low effort is not the same as zero effort. I like the omnibox because I just click and type, no need to spend a millisecond deciding which box I should click into.

I can see what you describe as the next step, so people don't have to bother understanding, or thinking about if they do understand, the difference between "cnn" and "cnn.com". Or I suppose those who type slowly may prefer to omit the last four characters purely for that reason.

Comment Re:I wonder how much hyperloop will really cost (Score 1) 157

I hope Elon Musk isn't getting arrogant, with the push into communication satellites, and hyperloop. The size of the hyperloop vehicles, suggests that it will have a lower capacity than a high speed rail line.

But much higher velocity, which can be combined with frequent runs to create high capacity.

If a high speed rail line wanted to, it could run the long, double deck high speed trains from Japan, that can carry ~1,600 passengers, every 3 minutes. Multiple trains could be stuck end to end.

That would provide massive throughput, but higher latency.

I have a friend at Google that says the real backlash was internal, and he thinks Matt Cutts even threatened to quit over this.

(I'm a Google employee)

Internal backlash was massive, and as far as I can tell hugely stronger than the fairly mild complaints outside the company. The strength of the internal opposition took me by surprise. I understood that while Google doesn't wish to censor the web it also doesn't wish to be the entity serving up sexual content. That seems like a reasonable position to me. I thought the 30-day notice was a bit short, even though the terms of service only offer 14 days, but other than that it seemed reasonable to me, basically bringing blogger into line with the policies in place for YouTube, etc., for years.

Many of my colleagues, however, vehemently disagreed, calling it censorship, application of one region's values upon the world and generally declaiming it as the beginning of the end for Google as a force for openness and access to information. Many called the decision deeply inconsistent with Google's stated mission, "To organize the world's information and make it universally accessible and useful". The internal memegen system was awash in anti-censorship memes, and one of the memegen team went further and more or less shut the system down in protest, replacing it with a complaint about the blogger shutdown. Eng-misc, a high-volume internal mailing list for random discussions of, well, anything, was overrun with threads complaining about it. The founders got hammered with questions and complaints in the weekly company-wide TGIF meeting (which is actually held on Thursday these days, so more Googlers around the world can see it live).

It's been quite the storm.

As soon as the internal reaction started I expected the reversal, though it went further than I expected. I thought the result would just be more notice, maybe 90 days. But I suppose that's because I thought the basic decision was reasonable, and only the short notice unreasonable. Many others felt differently, obviously.

It's going to be interesting to see if this provokes re-examination of the YouTube and G+ policies. I doubt it, but I was wrong about the nature of the reversal, too.

Actually, it's the Return on investment (ROI) that matter in business. Or in other word, how many time it'll take to make enough profit to cover the cost of the initial investment. And in this case, the US$9.95 billion California High-Speed Rail is a huge example on how much money you can make on transportation.

Using the $56 million per km quoted on California High-Speed Rail as the low estimate of how much it would cost to build a hyper loop, the minimum cost across the US would be $56 million per km * 3000 miles * 1.6 km per mile = $270 Billion dollars MINIMUM. That's going to have a hell of a long ROI, and because of that I can't see anyone in their right mind financing such a project in the near future.

Did Musk ever propose transcontinental hyperloops? I don't believe he did. As I recall this was always intended as a regional transportation technology, something for distances short enough that air travel is inconvenient because of the airport delays at both ends, but long enough that traditional train travel is too slow.
