I don't think 10 hours per week is unreasonable or impossible. And I don't see why you need to be a hypochondriac or narcissist to prioritize physical activities. The article does not define the required level of exertion, but I assume things like biking, ping-pong/pickleball, soccer, etc all count. A lot of physical activity can be cheap, though it is more challenging in the winter.

I mostly looked at the pictures.

Visa is valued at $585B and Mastercard is valued at $444B. Is Stripe making more revenue per transaction than Visa and Mastercard?

Lithium NMC, which I think is the most common, is 3.7V. Lithium iron phosphate, which some power packs do use, has a nominal voltage of 3.2V.

Why is this an app and not a website?

Yes, they are on the BIS Commerce Control List. It doesn't need to be particularly advanced to be export controlled.

5A001.g Passive Coherent Location (PCL) systems or equipment, “specially designed” for detecting and tracking moving objects by measuring reflections of ambient radio frequency emissions, supplied by non-radar transmitters. Technical Note: For the purposes of 5A001.g, non-radar transmitters may include commercial radio, television or cellular telecommunications base stations.

SpaceX isn’t providing a discount to student groups. The program, Cubesat Launch Initiative, is funded by NASA and covers the cost of launch and integration into the deployer.

Who are the lenders and why do they keep lending when their is a history of default from the PE-owners?

Thanks for the reply. Are you able to comment a bit more on the costs. I’m particularly curious about your statement about balloons being orders of magnitude less expensive than satellites. Does that mean 1/1000 the cost or 1/100 the cost? I ask because LEO satellites with usable power (50W) no longer cost millions, or even a single million to put on orbit. And they have operational lifespans of 5 years.

Are you staying under the 12-pound ICAO-limit for a payload (which must be split into two packages)? If so, how much power is continuously available to the payload and how long can each balloon stay aloft?

Why do unsubscribe-regulations work so well? What is the punishment for not complying and is enforcement particularly swift?

Which part of it do you think is not true? The written application is not extensive at all. It takes maybe 1-hour of focused time. That’s all I had ever spent on the written part of the application and I’ve been interviewed three times as a solo founder. And the interview really is just ten minutes long, though sometimes they go a little over the limit.

Alternatively, the aperture of the antenna on the satellite can be increased. So high-gain from space, but low gain on Earth, which is the approach of AST SpaceMobile.

If you are being paid to launder money, isn't the fee about 20%? My source on that is the Netflix series Ozark. Assuming that 20% is within the realm of reality, I assume that the margin on drip-coffee is substantially higher. Maybe 60% margin on coffee?
