As a pilot I think these are nifty aircraft. However, most or all are unlikely to be certified for "flight in known icing" (FIKI) weather conditions. That means the aircraft would not be permitted to fly in some types of weather, and that is a problem for a commercial airline.

We don't advocate feeding wild animals since it introduces long-term, bad behaviors such as a lack of foraging skills, attracting too many animals to an area, and increased reproduction rates due to an abundance of food. It also increases the risk of a disease outbreak due to more animals in the area. So why do we promote basic-income programs for younger, healthy people?

Kaspersky sued the DHS, not the Executive Branch of government.

Humans have gotten good at fire suppression, which results in a dangerous buildup of natural fuels. The same thing happened in British Columbia this Summer. A researcher from the University of Victoria estimated that there were naturally-occurring forest fires in areas of British Columbia approximately every 20-30 years. So given that large fires were suppressed and there was a huge buildup of fuels, then *boom*.

Agree. Apple is a high-end company and put a store where the money and opportunity is for them. Look at Walmart. They are pulling out of some markets due to profitability problems (some with a high degree of theft) such that the money is just not there for them.

In theory doing microservices is OK, but there are some huge risks (I'm seeing it in real-time with a couple of big customers). Beware isolated copies of data behind the microservices. There is too much "academic pontification" here coming from some Architects. Is your organization really ready to keep data in sync between a microservice's representation of that data and the System of Record's (SoR) representation of that data? How good is the code? This gets messy quickly. What are you going to do when (not if, but when...) the data gets out of sync between the multiple representations? If you're doing a financial system then how will you achieve compliance? Dependencies. Micro means more things. Who needs what? How do you manage change? One customer is testing a tool called 8folios to help with this.

All potential pilots learn about "density altitude" in ground school. https://en.wikipedia.org/wiki/...
