Comment Re:Sony, NEC and Panasonic (Score 1) 49

I have owned or used several pieces of Panasonic video equipment back in the day. A compact VHS-C consumer camcorder and some full-sized pro S-VHS cameras and VCRs and editing equipment. I also owned a Panasonic Toughbook laptop (one of the W series semi-rugged ones) and a Panasonic Lumix pont-and-shoot camera.

What happens when the first generation of kids comes of age, notices they never gave consent to be confined to a ship for their entire lives, and decides to turn around?

Religion is a tried and true solution used by humanity many times previously to solve just that very same issue.

Personally though I think that the engineering problems dwarf the social ones. Humanity's longest lived buildings are only a few thousand years old, and they are basically ruins not fit to live in. We have no clue how to build anything that would stay intact and fit for purpose over 500 years.

Notre-Dame cathedral was built in 1163, and is still fit for occupation. That's 863 years. But it's had some damage over the years.

Comment Re:What about Acela (Score 1) 242

Acela has been around since 2000. Acela trains are the fastest in the Americas, reaching 150 miles per hour (240 km/h) (qualifying as high-speed rail), but only over 49.9 miles (80.3 km) of the 457-mile (735 km) route

That's 9.16% of the route. It's less than 1/10 high speed rail!

Indeed, but it exists and has for 15 years. So, it's not really accurate to say this new service is the first ever.

Amazing! the GP is now modded up to +4!!!

Burning a gallon of gas creates 20 lbs of CO2.

So 100 gallons of gas creates a ton of CO2.

So $1.50 cleanup per gallon of gas at the low end.

Weight of a gallon of gas:

Many owners pump their cars with fuel but never stop to think about just what they’re pouring inside the tank. Gas has unique properties, like weight and density, which all play an essential part. In this piece, we’ll try to understand how much gas weighs and why that matters.

The weight of a gallon of gasoline is about six pounds. There is a slight difference depending on the type of gasoline and its additives. Unlike water, which weighs about 8.4 pounds per gallon, gasoline is 25% lighter.

So according to the +4 post we are now creating mass out of thin air, generating 20 pounds of output with only 8 pounds of input and managing to run our cars on apparently free energy on top of that along the way.

Seriously?

Obviously the air used to oxidize the fuel was not weighed It still counts as an input though. It's just assumed to be always available for reactions that take place in the earth's atmosphere. I suppose the chemists could do the math (wolfram alpha was surprisingly not helpful when I asked it how many atoms of carbon are in a gallon of gasoline).

Comment Re:Reminds me of Andy Weir's _Artemis_ (Score 1) 246

In _Artemis_, Andy Weir writes about a nuclear reactor on the moon, that uses a lot of radiator panels to cool it. I just thought it was cool that the NASA name is also Artemis.

There's only one Greek goddess of the Moon. The name has been recycled endlessly since the dawn of the Space Age. There are dozens of examples in fiction and a dozen in real world projects.

I get that. I think the book is a good story, with believable lunar technology, including the nuclear reactor.

Comment It's not sufficient to only block remote images. (Score 1) 217

It seems like trackers could just embed a CSS style sheet, or, a font with a unique address. In fact, any remote content could contain a uuid domain name, e.g. 8a7636d3-3ce4-4a6a-acb5-089eca201a4b.example.com. But, if e.g. gmail proxies all remote content, all the tracker learns is just that you actually opened the email (and possibly the fact that you're using gmail), rather than your remote ip.

Unlike in 2008, in 2020 almost all big websites exclusively use https encrypted traffic. Spoofing DNS may be possible, spoofing site certificates is not.

If you can spoof dns, you can trick letsencrypt into giving you a certificate. Fortunately, letsencrypt already issues dns challenges from several geographically distributed hosts, so it's less likely you'd be able to trick all of their upstream dns recursive resolvers.
