In "Story" website section:

"This conjecture says that 47,176,870 is the maximum number of steps that a 5-state Turing machine can run before halting (starting from all-0 memory tape)."

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.

Clearly all the people complaining have never made a typo in their lives, and are unable to deal with the horrible inconvenience of having to actually deal with one!
rrss · 3 years ago
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

> Or does someone at NASA not understand that Baja California is a state in Mexico?

I think they understand perfectly, and the capsule splashed down "off the coast" of "state of Mexico".

No different from saying "The capsule splashed down off the coast of British Colombia" or "The capsule splashed down off the coast of Queensland".

They know perfectly well what Baja California is and where it is.

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"

I had a question about the pictures at the bottom of the post. Is this an example of "wire wrapping"? If so what mechanism is actually holding the wire securely around those metal posts(terminals?)

Yes

> If so what mechanism is actually holding the wire securely around those metal posts(terminals?)

The wire is wrapped around the posts several times, with no other mechanism. https://en.m.wikipedia.org/wiki/Wire_wrap has a good close up picture of one connection and a description of the details (including some info on how this forms a reliable connection)

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.

rrss commented on Ask HN: What field in computer science will be AI proof    · Posted by u/wara23arish
rvz · 3 years ago
It is fundamentally based on initial hype and mania of other HN ChatGPT posts. Other than that, nothing.

Ask ChatGPT to solve unsolved mathematical and computer science problems or any basic international mathematical olympiad (IMO) questions and it falls before the starting line and will give incoherent answers.

Even if it moves an inch past the line, it cannot transparently explain as to how it got there in the first place.

rrss · 3 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.

rrss commented on Placing #1 in Advent of Code with GPT-3   github.com/max-sixty/aoc-... · Posted by u/maximilianroos

Competitive in what? Advent of Code as I see it is widely regarded as a chance for people to learn a new programming language or to have fun. No one I know try to "compete" in AoC.

On the other hand, if ChatGPT provides a competitive edge in CodeForce problems then it would be worrying indeed.

rrss · 3 years ago
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.

A prison term for not registering with some bureaucratic state agency? Why?

The “California Bureau for Private Postsecondary Education”? This is indistinguishable from parody.

rrss · 3 years ago
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?

My advice is this:

Become a different person.

Take your life and incinerate it. Not literally of course.

I mean completely change what and who you are.

You’re an accomplished software engineer at 30? Great. You’re done doing that.

Go buy a $15k trailer, get a truck, and hit the road. Stop looking at screens, only read books. Stop working a job behind a desk, find something else, or if you can afford it don’t work at all.

I suggest reading CrimeThInc: Days of War, Nights of Love. https://crimethinc.com/books/days-of-war-nights-of-love

Pick up a guitar, learn to farm, meet some nomads. Do it all in another country. Break the law. Do whatever you feel like. Don’t hurt people, obviously, but you’re probably a sane enough person to not want to anyway. Learn a new language. Stop speaking your old one. I mean, really, and truly, break out of the matrix. Go to the edges of your universe, like the “Thirteenth Floor”. Get fit, dissolve your old identity. Become awesome at yoga, or weightlifting, or Jiu Jitsu.

You really can choose to become unstuck. Fly to Europe, buy a bike and a tent, and just go, man. Figure it out later. What’s there to be afraid of, really?

> 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.
