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.

Comment How is it secure? (Score 3, Insightful) 50

There's no possible way they could have a secure electronic ballot . It's not possible to both transmit the ballot securely while at the same time ensuring that the conflicting objectives of vote secrecy and vote uniqueness. In order to ensure uniqueness (so the same person can't vote multiple times), there has to be a unique id (such as a token, username&password, or even voter id number, ssn, etc.) that is linked to a single human being. But, in order to to have a secret ballot, there has to be no way to link a specific person with the vote that was cast. With in person voting, or even mail-in voting, the two things are separate (using a separate inside envelope containing the ballot, and an outside envelope containing the voter id in the case of mail-in voting). With online voting over the Internet (and I'm counting the satellite link to the ISS as part of the internet for this discussion), they must necessarily be both provided in the same session.

In the article, it mentions that there's a secure link from the ISS to the computer on the ground. But what happens then? Is the ballot printed out and mailed in? If so, ground crew have the potential to see the ballot. Or, is it transmitted electronically, in which case, the above point about transmitting both the unique id and the vote.

Why didn't the astronauts just file an absentee ballot before leaving?

Open Source

Security Researcher Troy Hunt is Open Sourcing the Have I Been Pwned Code Base (troyhunt.com) 25

Security researcher Troy Hunt: Let me just cut straight to it: I'm going to open source the Have I Been Pwned code base. The decision has been a while coming and it took a failed M&A process to get here, but the code will be turned over to the public for the betterment of the project and frankly, for the betterment of everyone who uses it. Let me explain why and how.
