I think the notion was to fit masts to existing container ship and stacks, and I gsve it scant attention as my intuition (I once studied actual civil/mech engineering prior to jumping ship for applied math) suggested masts are better as integral parts of ships rather than bolt on after thoughts.
EDIT: Wingsails to reduce cargo ship fuel consumption (April 2023)
https://news.ycombinator.com/item?id=35426482
I’m Joseph, and along with Arpan and Bailey we are the founders of OutSail Shipping. We’re building a sail the size of a 747 that rolls up into a shipping container.
When deployed, it will generate thrust from the wind to reduce the fuel consumption of a cargo ship. An array of these devices will reduce fuel consumption on ships by up to 20%. These sails are easily stowed and removed to cause no interference with cargo operations.
Here’s a short video showing our prototype:
Not quite as I remembered .. kite sails, et al. are a good idea, I'm still a bit torn by the physics of a container deployed boom extension sail and the thrust transmission to the ship. Still, I haven't modeled it, so take my thoughts with a grain of salt.
EDIT2: Both links appear dead, so I guess that was a swing and a miss. Still, good to see such ideas pursued.

You mention container ships. I haven't seen anything explicit on these, and I think the reason is probably that they cruise much faster than bulkers and tankers, which means the potential savings from sail is smaller. I would have thought 20% optimistic even for a new-build.
You should be using a unique randomly-generated password for each website. That way, one breach doesn't lead to multiple accounts getting hijacked AND you'll know which passwords were breached solely based on the website list. The only passwords I still keep in my head are:
1. The password to my password manager
2. The password to my gmail account
3. The passwords for my full disk encryption
I used to reuse the same password for everything, and that lead to a pretty miserable month where suddenly ALL of my accounts were compromised. I'd log in to one account and see pizzas I never ordered. Then I'd open uber and see a ride actively in-progress on the other side of the country. It was not fun.
That can be reasonable for something like medicine or structural engineering. But is it appropriate for a developer cranking out Javascript or Excel macros? This is pulling up the drawbridge behind you, excluding anyone who comes to the profession through informal means - and in my generation, that meant almost everyone. It also means that you will need to determine how much of your time you dedicate to politics.
