I used PyPy extensively at a previous employer. The use case was to accelerate an application that was CPU-bound because of serde, which could not be offloaded using multiprocessing. PyPy resulted in a 10x increase in message throughput, and made the project viable in python. Without PyPy, we would have rebuilt the application in Java.
gc.freeze prevents considering the objects in gc, but doesn’t disable reference counting so you’ll still have CoW issues. PEP 683 introduces a way to make an object immortal which disables reference counting, which will address that issue.
Florida is connecting Miami, Ft Lauderdale, and Orlando this year for a total cost of $3-4 billion. That’s $7.3 million per mile, and it was mostly paid for by private enterprise instead of the government. Development started in 2012, with Miami to West Palm Beach opening in 2018. CHSR started development in 2008, and isn’t slated to operate anything until 2029. When it does operate, it’ll link Merced and Bakersfield.
Florida will be operating the fastest trains in the US this year.
It uses a lot less energy for people to live in a warm climate with air conditioning than a cold climate with heat. The US spends four times more on heating than cooling, primarily because of greater temperature differences.
Responsible environmentalists should set an example for everyone else and move to an area where heat isn’t required, then they can also choose to live without air conditioning.
The Texas power grid failed in the winter, not the summer.
I was lucky enough to get to tour the clean room where they were fabricating the microshutter array at Goddard many years ago. Unfortunately I don't have any pictures, since this was before smart phones. I think that really helps contextualize just how long the development process of something like this is. And maybe what it could be capable of if it was built with today's technology.
