Comment: Makes sense (Score 2, Interesting) 395 395

Makes perfect sense to me. I talk to people on the phone all the time, but it seems rude to just call someone without first sending an instant message or text to ask if they're free. My usual response when someone IMs me asking if I'm free is to give them an estimate (usually 5-15 minutes) of how long I need to complete what I'm working on so that I'm free to talk. A phone ringing unexpectedly is an annoying interruption and listening to a voice mail is a nuisance.

No AC required. USB powered, bridges wifi to RJ45.

Even with the added cost of a USB battery (or the sort available everywhere for recharging phones) it's still well under you $100 laptop as well as smaller and lighter. The OS configuration may be harder for people who are not familar with concepts like iptables and/or network namespaces.

Comment: What about the graphics? (Score 1) 121 121

In a related but definitely separate question, what are some resources for kids who are interested in creating the graphics for games? Are they all horribly complicated or are there some good starter tools that kids can use to bridge the gap between utterly awful and years of profesional experience?

Incorrect. 2000 MPH has one sig fig. Intermediate zeros (2001) and trailing zeros to the right of the decimal (2000.0) are significant but trailing zeros to the left of the decimal are not unless somebody changed introductory Physics since the 90's.

Of course if you want to be unambiguous you should write 2.000 x 10^3 or 2 x 10^3 so we can distinguish between 4 vs 1 sig fig. By moving the trailing zeros to the right of the decimal we've declared them significant. But it is utterly wrong to assuume that 2000 has four sigfigs. It has one unless the precision is specified elsewhere. By "utterly wrong" I mean "you will get points off in high school physics" wrong. That's straight out of the basics of the first sig figs lesson.

Steve Jobs was born in 1955, Elon Musk in 1971. Are you sure you want to compare them based on accomplishments to date? I think we can assume Jobs won't be accomplishing anything else, but it's a bit premature to judge Musk's lifetime achievements. Lots of people live into their 70s, some are productive into their 90s, especially if they can afford expensive medical care. Even if Musk were to die at the same age Jobs did, you really aren't giving him a fair comparison unless you restrict your comparison to things Jobs had accomplished by Musk's current age.

Then slowly adding solid food, starting with only raw foods. It took a couple of months to work up to eating chicken again.

I'm going to have to pass on any diet that includes raw chicken. I'm also very skeptical of the claim that drinking juice has any benefits that aren't present in just eating whatever the juice came from. Bottled juices are convenient because of the shelf life. If you're sticking a fresh item into a juicer you could have gotten all the same benefits by just sticking it directly in your mouth. Your stomach liquifies everything anyway.

If you've got a GI disorder that prevents you from digesting or eliminating then you'll need to be on clear fluids and IV but for non-GI disorders the rest of your body doesn't care whether the food was solid or liquid when it entered your mouth. Either way it was broken down into its fundamental constituents before it passed into your bloodstream.

No, NYC is too corrupt and too union. It doesn't help that everything in NYC is expensive, but don't imagine for a minute that running high speed fiber in NYC is just a matter of buying the fiber and paying a competitive hourly wage for somebody to run it through a conduit. There's definitely a reason why no little startup is just buying some cheap datacenter grade GigE switches and running new fiber building to building in NYC.

The Sum of All Thrills ride at Epcot basically does this. It's not a roller coaster, it's a two person capsule on the end of a multi axis robotic arm. But the result is the same. All sorts of video and audio options synchronized to multidirectional movements and spins.

Interesting interpretation of the word "lost" you've got there. Right in the headline of the article you linked to it says "AT&T lost $3.9 billion in Q4 2012, earned $7.3 billion profit for the year".

But I suppose you could be referring to $7.3 billion profit for the year as 3+ billion per quarter if you're bad at dividing by four.

Nevertheless, according to page 30 of AT&T's annual report http://www.att.com/Investor/ATT_Annual/2012/downloads/ar2012_annual_report.pdf the dollar amounts (in millions of dollars) for "Construction and capital expenditures" for the past few years are:
2012 19,728
2011 20,272
2010 20,302
2009 17,294
2008 20,290

So 17-20 billion dollars per year in construction and capital improvements. If you've got evidence to show that AT&T is NOT investing tens of billions of dollars per year in improving the network you should maybe contact the SEC or FCC. Otherwise, it's not really polite to imply that AT&T isn't investing in infrastructure without evidence to support your claims.

Disclaimer: I work for AT&T but not in wireless or in finance. But I'm well aware of AT&T's public communications of how much the company is investing.
