> So, we can run up to this number and either the machine will stop - and we'll go to the next one until exhaust the whole set - or the machine won't stop, and we'll refute the conjecture

No, you do not refute the conjecture if you run up to this number and a machine does not stop. Finding a machine that runs for more than 47,176,870 steps is easy - there are plenty of machines that run forever. The trick is that it needs to stop.

lol

right, it's a typo, it doesn't matter, and there was already a reply 4 hours before yours that said as much, so i'm not sure what you were aiming to contribute with the reply that doesn't acknowledge that it is a typo

"all the people complaining" = up to 1 person

> No different from saying "The capsule splashed down off the coast of British Colombia"

except for the comma in the middle of the name, which was ytdytvhxgydvhh's point:

"The capsule splashed down off the coast of British, Colombia"

this is neat, but the AP CS A ("AP Java") curriculum and test is extremely boring, and primarily tests for ability to write very basic Java programs using pencil & paper.

I think the college board threw out the actual computer science part (i.e. everything except java details) years ago.

how is this relevant to OP's concern?

most software engineers today are employed to solve unsolved mathematical and computer science problems or IMO-style problems.

Hi, some of us try to compete in AoC. For me that is part of the fun.

In several previous years I have rescheduled things so I can stay up until the problems are released in my time zone to see how high on the leaderboard I could get.

It is sad that the AoC leaderboard will now just be filled with GPT entries.

Why is it unreasonable to have people in a government agency to address fraudulent colleges and stuff?

Do you feel the same way about the bureau of consumer protection in the US FTC?

> What’s there to be afraid of, really?

Incinerating your life, trying all these new things, only to find that the emptiness returns shortly, and now it is no longer paired with a dependable income.

Large-scale solar:

> requires 5.6 GW of solar energy. For context, this is roughly 10 days of solar panel production in 2021, though the industry continues to grow explosively. 5.6 GW consumes roughly 112 square km of land

It is very common for water projects.

I think it comes from reservoirs, since the area is measured in acres and the depth in feet.

NASA and contractors are also leveraging decades of research and billions upon billions of taxpayer dollars put into this industry already, or have the same opportunity for leverage and are failing to effectively leverage it.

Now do the cost for SLS based on the total cost to date for NASA and all contractors since inception, including the costs for Apollo and the shuttle.

This is not just inflated, it’s 100% bogus - this is not a reasonable way to estimate development costs for a launch vehicle.

the Wikipedia page for SLS references https://oig.nasa.gov/docs/IG-22-003.pdf

> We project the cost to fly a single SLS/Orion system through at least Artemis IV to be $4.1 billion per launch at a cadence of approximately one mission per year.

> The cost per launch was calculated as follows: $1 billion for the Orion based on information provided by ESD officials and NASA OIG analysis; $300 million for the ESA’s Service Module based on the value of a barter agreement between ESA and the United States in which ESA provides the service modules in exchange for offsetting its ISS responsibilities; $2.2 billion for the SLS based on program budget submissions and analysis of contracts; and $568 million for EGS costs related to the SLS/Orion launch as provided by ESD officials.
