The book is interesting, but the level of detail he goes into in some of his speculation is completely unjustified. It's kind of ridiculous. "There's no sense in being precise when you don't even know what you're ta

The telcos are running utilities and should be regulated like utilities. And they should especially be regulated this way if they are heavily subsidized build the infrastructure in the first place.

Biking in Soma is incredibly dangerous. Everyone I know who bikes there has had an accident at some point in the last few years. And I suspect its getting worse with Uber and Lyft drivers who pour in from elsewhere around the bay and have n

I don't think Paul Graham owes Michael O Church a damn thing. PG has always been clear that he built this site as a place for a certain type of reasoned discourse with a certain tone. And he enforces that as he pleases, as he should. H

This is certainly kind of legislation that could come down to a close vote, especially if IV throws around some lobbying dollars against it. A little advocacy will go a long way, and it will be very interesting to see if the tech industry g

I tutored teenagers in physics and math for a while to make ends meet. And they love snapchat. They are also basically ready to be done with facebook. There are two reasons they prefer snapchat to facebook and texting, respectively, both

Have to interject here on the off chance that some gmail engineers are paying attention. That's nice that you like it, but forcing the new compose on users is just plain inexcusable. It breaks a number of things for me that I actually use i

No can do. I refuse to turn shortcuts on because there are at least 2 (and maybe more I'm not aware of) ways to send the email I'm currently drafting. Command + Enter, or hitting shift, then enter. I've learned from past email programs that

The new compose has at least 4 things that are broken for me: 1) When you hit "forward", it hides the subject box, even though the majority of the time when I hit forward I want to delete the "Fwd:" from the subject line. Especially when se

I did try it just now. See my above comment.

Disaster. 1) I just turned it on, and it is not customizable at all . You cannot create custom tabs, and you can't even pick what goes into the tabs they have created. 2) When you turn it on, it disables Gmail's multiple inbox. Multiple in

I'd say the goal is to find a survivable planet that can support billions of people. In that sense, the amount of water ice that is in a couple of permanently shadowed craters is really negligible. And on Mercury you're talking about only a

Mars is a non-starter? I think you've received some bad information. Average radiation on the Mars surface is 10-20 rem/year. With a thicker atmosphere it will be less. And for people spending 12-15 hours a day indoors in shielded dwelling

But the goal isn't to just colonize any old planet. It's to colonize a place we can successfully terraform. Mars is the clear winner in that respect, and it's not close. Mercury needs basically a planet's worth of water and atmosphere to be

This is the best explanation. What I think a lot of the public doesn't realize is where the money comes from when you walk into a bank and you get a loan from that bank (instead of depositing the money from somewhere else). They basically a

ITAR, like all US federal regulations codified in the CFR, have the full force and effect of the law. See the first couple paragraphs here for further explanation: http://library.law.unh.edu/AdminLaw How do you know if something is subjec

Absolutely yes this is a risk. Do not do this. The International Traffic in Arms Regulations (ITAR) is not something you want to mess with.

If only someone had predicted this exact possibility 3 years ago... "[2] In theory you could beat the death spiral by buying good programmers instead of hiring them. You can get programmers who would never have come to you as employees by

That's not correct. The US government doesn't subsidize SpaceX, it purchases launches and technology. It's just a customer. And it buys those things for much cheaper than before. You as the tax payer are actually saving money compared to wh

I would put it this way. They're not responding to your ideas, they are responding to you . A thought experiment: imagine Larry Page, or Jeff Bezos, or Elon Musk is sitting across from one of these people, selling your same idea. The exact

Bezos, or his handlers anyway, can be pretty outrageous with this kind of stuff. Water landings of VTVL's have been talked about since the 1960's by various people. It would be pretty ridiculous if he was granted the patent for it.

The first stage isn't going at orbital velocity of course, but the second stage is. The SpaceX announcement for Grasshopper refers to both: http://www.space.com/13140-spacex-private-reusable-rocket-el... I'm sure they'll start with just t

You won't find a bigger supporter of SpaceX, and no one wants Grasshopper to be doing operational flights tomorrow more than I do. But it will take 10 years, minimum. Keep in mind no one has successfully done powered vertical landing from o

Depends on how much time you have and how big we're talking about. If you have years, or lets say a decade, you'd probably try a bunch of things in parallel. Some strategies could be crazier than others, but you wouldn't waste too much time

It's normal for any NASA mission. Your average comsat launch isn't going to get any press coverage, and the military sure isn't holding press conferences after their classified missions. But pretty much every NASA science and space station

The space industry's go-to place for minute by minute updates on any launch is Spaceflight Now: http://www.spaceflightnow.com/falcon9/005/status.html Here's the last couple of updates: FRIDAY, MARCH 1, 2013 1527 GMT (10:27 a.m. EST) "It a

If I had to guess, I'd bet workers can now do 8 hours of work in 3, but because we're required by cultural norms to be in the office 9 to 5, people find things to waste time on to stretch it back out to 8 again. (Hmm, there's lots of places

I agree, that's the key to the whole thing right there. It says to me that, if I had to guess, I'd bet he didn't call them and headed out despite the range being short, because he knew he was about to be stranded and have a tantalizing stor
