Don't forget slowing down for traffic, getting cut off, keeping speed on down hills ... and then the reverse of those. Batteries sized right to store that energy can be useful; they can also just be straight up charge on the long straight while the motor/generator is operating at peak efficiency.

This^^^ and then use batteries for when you DO actually stop/start, accelerate to pass, and for pulling up a hill so you don't have to ramp up the engine RPM too much to generate the electricity needed to power the electric motors only up that hill.

Hint: even long haul trucks don't run full throttle all the time. So the question is, how do you recover the massive amounts of energy when they have to slow down/ hold on the down hill and then use it when you need to accelerate again/ pull back up the hill.

Which part of applied thermodynamics don't the rest of you understand.

You, him, and the R's don't get off that easy. The No True Scotsman argument holds no water. He calls himself a Republican, the Republican party accepts and supports him, and probability theory says at least one registered Republican voted for him; if not two.

Reddit Users Are the Least Valuable of Any Social Network (cnbc.com) 184

Reddit's latest funding round values its users at a lower price than any other social network. "The company announced Monday it had raised $300 million in its Series D investment round at a valuation of $3 billion," reports CNBC. "CNBC previously reported the company's annual revenue topped $100 million, according to sources familiar with the matter, and at 330 million monthly active users (MAUs), this would make Reddit's average revenue per user (ARPU) about $0.30." From the report: That estimate would make Reddit's ARPU significantly lower than other social networks, even those with similar MAUs. Twitter, for example, reported 321 MAUs for its latest quarterly report, and with annual revenue of about $3.04 billion in 2018, that would make its ARPU about $9.48. Facebook reported 2.32 billion MAUs in its latest report and ARPU of $7.37. Snap does not report global MAUs, but reported $2.09 ARPU in its latest quarterly report.

Pinterest, which has yet to go public but is preparing for an IPO this year, says on its website it has 250 million monthly users. Pinterest declined to comment on their revenue, but a September article in The New York Times said the company was on track to top $700 million in revenue for 2018. That would bring its ARPU to about $2.80. While Reddit's value per user is much lower than its peers, it is betting its access to a valuable demographic will appeal to advertisers and potentially even draw their dollars from larger rivals like Facebook and Google. The company said half of its MAUs are between the ages of 18 and 24.

Key West Moves To Ban Sunscreens That Could Damage Reefs (miamiherald.com) 90

Yesterday, the Key West City Commission unanimously voted to ban the sale of sunscreens that contain two ingredients -- oxybenzone and octinoxate -- that a growing body of scientific evidence says harm coral reefs. The measure must now be reviewed again by the commission before it becomes law. The second vote is scheduled for February 5th. Miami Herald reports: Environmental researchers have published studies showing how these two ingredients, which accumulate in the water from bathers or from wastewater discharges, can damage coral reefs through bleaching and harming the corals' DNA. In some instances, the corals can die. A Feburary 2016 study in the Archives of Environmental Contamination and Toxicology examining the impact of oxybenzone in corals in Hawaii and the U.S. Virgin Islands concluded that the sunscreen ingredient "poses a hazard to coral reef conservation and threatens the resiliency of coral reefs to climate change.''

Last year, Hawaii banned the sale or distribution of any sunscreens containing oxybenzone and octinoxate, a measure that will go into effect on Jan. 1, 2021. It was the first state in the nation to implement such a ban. In Florida, the website for the South Florida Reef Ambassador Initiative, which falls under the state's Department of Environmental Protection, tells divers to "Avoid sunscreens with Oxybenzone and Avobenzone. The benzones are compounds that are lethal to coral reproduction in very small amounts." Experts who have studied the issue say sunscreens with zinc oxide or titanium dioxide, which are minerals, also block ultraviolet rays. They create a barrier on the skin that deflect the sun's rays .

Comment NFC? (Score 1) 300

So I know there are some NFC security factors what probably need to be tightened up before I want something pushed to my phone, but isn't this a perfect opportunity for NFC on the pay terminal? We already have CC terminals with touch to pay. As a first step, well before we start mandating and/or banning anything, what about passing contactless payment receipts back to the customer's device and then displaying it? Second step, even for CC contact payments the customer would hold their phone to the terminal and get the receipt.

Just an idea of how to do it without giving out email addresses, which take time, rubs me the wrong way, and does seem like a bigger add to the terminals than NFC.

No need to ban mining. Ban use in transactions and you make it worthless. Boom, no one will mine it except for the darkest of web transactions and even then probably not. But if they do it'll be so few as to not matter AND have enough of a power density footprint it'll be easy to detect like grow houses. Then just start jacking up their electricity rates until they stop. Not even a need to raid or fine just keep collecting via their electric bill >;-)

Crystal City is the opposite of affordable. I mean yeah the actual literally named area of Crystal City has semi-affordable apartments, but not a lot of them and if you want more than the basics you're going to have to look into even pricier areas or endure a horrid commute (and still pretty high prices). Living in the greater DC metro area is cheaper than NYC, but not that much. https://www.numbeo.com/cost-of...

Still ... yeah ... NYC seems like an odd choice. Frankly looking at Northern VA I'm surprised at Crystal City other than the cheap vacant office space and metro access and proximity to DC proper and literally walking distance to the Pentagon, and .... OOOOOOhhhhhh I get it.

Thank you for a very accurate, non-car, analogy.

When I'm interviewing for certain roles there are many times when my feedback to the recruiters is, "this person will get bored on project X ... send their resume over to Billy Bob who's doing some more exciting almost 'new-science' stuff"

Bottom line is I'm not gonna ask (or pay) a CS to spend their entire day coding up basic web pages using a nearly 10yo tech stack ([cough] federal [cough]). Instead, go find me someone who just finished a coding bootcamp that wants to build their resume and while showing me how they can take the client's aging tech stack into the modern era.
