Does this "$1B in revenue" include the $ that customers have deposited in order to buy cryptocurrency?

Bob is out $1000 until he finds a "greater fool".

The zero-sum aspect occurs if at some point all participants cash out.

> As long as people bought bitcoin and ethereum, they probably will end up positive.

This isn't possible - the bitcoin market is literally a zero-sum game. One person's gain can only come from another's loss.

Adding a photo of the actual aircraft would also be nice. From the website it's hard to tell whether this is a real business that's currently in operation, or just a site mock-up. Have you actually started flying yet? I can't tell.

"I'm becoming more convinced that Bitcoin must be in a bubble."

Well, what else could it be?

»The G5 has three USB 2 ports, two FireWire 400 ports, and a FireWire 800 port. In my life I have never used FireWire to transfer data. I will probably go to my grave having never used FireWire.«

Same.

aren't "bitmapped" and "raster" pretty much synonymous?

His thesis is from 1966, an era in which (1) it is likely that he typed it on a typewriter, and (2) he was still almost completely able-bodied.

Didn't BeOS have some awesome database-like file system indexing and query system?

That $100M clearly is dominated by the capital that is to be invested. The use of the verb "spend" is perhaps a slip indicating an opinion on the chance of positive ROI...

"The company is spending about $100 million annually on the funding of startups, he said."

"All told, Dell Technologies Capital has invested in more than 70 startups. It puts in around $3 million to $10 million initially and usually in the A or B rounds, Darling said. The company provides more money in later rounds."

If your investment team that answers the question "Who should we invest in?" is consuming $100M itself... I need to change jobs.

Indeed, the linked article doesn't say anything about lack of sanitation, and almost implies the opposite.

»Imbruce, who's researched the Chinatown produce economy for over a decade, is the author of From Farm to Canal Street: Chinatown’s Alternative Food Network in the Global Marketplace. In the Journal she distills to Kadet the real reason Chinatown can keep prices low: “Chinatown’s 80-plus produce markets are cheap because they are connected to a web of small farms and wholesalers that operate independently of the network supplying most mainstream supermarkets.” While most of the rest of New York's markets get their produce from the Hunts Point Market in the Bronx, Chinatown sellers work directly with small neighborhood warehouses. Since they're operating in close geographic proximity, they can get fresh produce throughout the day from wholesalers, and therefore don’t need a store with refrigeration or a lot of storage space.«

A methane molecule is 72 times worse than a CO2 molecule in terms of "global warming potential" over a 20 year time scale and around 7 times worse over a 500 year time scale). However, we put a lot more CO2 into the atmosphere than we do methane. https://en.wikipedia.org/wiki/Greenhouse_gas#Global_warming_...

That's true. As a pollutant, carbon dioxide is almost entirely innocuous, except for its behavior as a greenhouse gas. In that role, carbon dioxide is the most significant driver of global warming: https://en.wikipedia.org/wiki/Greenhouse_gas#Natural_and_ant...

TLDR:

* Because beer was consumed as a source of energy rather than as an alternative to water, and high alcohol content was favored, it seems like the answer is "Yes."

* However, it's unclear whether early brewers could make drinkable beer at high ABV, throwing this conclusion into doubt.

That's an accounting detail.

> dark asphalt roof and direct sun would do it

But if you were going for cooling, you wouldn't go for a dark asphalt roof.

Looks nice. I like it.

But what are the percentages next to your degrees in the education part, like "B.E. CSE 72%"?

Yes; in fact they are preferred.

Seriously.

I have a cushy tech-job yet still drive the hatchback I bought fifteen years ago for $2000. Choices...

What do you mean here?

In which case the value will reach $0. That's called depreciation...

The power required to fly at constant altitude and speed is velocity multiplied the force of drag.

Energy is consumed to exert a force over a distance, but we're not moving against gravity ("constant altitude"), so no energy is directly expended to fight gravity.

Now, that argument cheats a little, because there is a relationship between lift and drag: compare induced drag (drag created as a result of producing lift) to parasitic drag.

The ozone layer starts at around 65,000 feet, which is about twice as high as where jets usually cruise.

> It goes to show how much energy just deals with drag in the current system.

All of the energy used during cruise flight (straight and level, accelerated) goes to drag.
