Python 3.10 is adding pattern matching in Python. This is a good official tutorial around it.

Few interesting use cases:

command = input("What are you doing next? ") # we want to use command.split() # one of the options is to use: [action, obj] = command.split() # but what if the input has multiple words # pattern matching can come handy here match command.split(): case [action]: ... # interpret single-verb action case [action, obj]: ... # interpret action, obj # we can use club it with specific values match command.split(): case ["quit"]: print("Goodbye!") quit_game() case ["look"]: current_room.describe() case …

Wonderful essay on how to build a good software.

Loved the introduction:

Bad software is one of the few things in the world you cannot solve with money. Billion dollar airlines have flight search apps that are often inferior to those built by groups of students. Established taxi companies the world over have terrible booking apps despite the threat they face from ride-sharing services.

How and when can it succeed?

What an article on fake Tethers in crypto market.

Tether Ltd. also says one Tether is worth exactly one US dollar. Can they do that? Well they say they can, because they hold $1 worth of assets for each Tether. But are those assets actual dollars? No, they are not. So what if the assets go down in value? Don’t worry; they will not. Okay, but can we at least see the assets? No, you may not.
