Show HN: Subth.ink – write something and see how many others wrote the same (subth.ink)

92 points by sonnig ↗ HN
Hey HN, this is a small Haskell learning project that I wanted to share. It's just a website where you can see how many people write the exact same text as you (thought it was a fun idea).

It's built using Scotty, SQLite, Redis and Caddy. Currently it's running in a small DigitalOcean droplet (1 Gb RAM).

Using Haskell for web development (specifically with Scotty) was slightly easier than I thought, but still a relatively hard task compared to other languages. One of my main friction points was Haskell's multiple string-like types: String, Text (& lazy), ByteString (& lazy), and each library choosing to consume a different one amongst these. There is also a soft requirement to learn monad transformers (e.g. to understand what liftIO is doing) which made the initial development more difficult.

I said "I love my wife". Apparently, I was the first. Then I said "penis". I was the fifth.

Neat!

"helloworld"

Your thought's hash is: 06ad246627b5f973559a1dbcf2a6b96791d9b15ed2d8cb45c344f98b14d10f76 Including you, 1 person had that thought already! First time was less than a minute ago, last time was less than a minute ago.

haha, cool.

I love this. Shouting into the void with the distinct feel, hope that if the idea was popular enough, it'd be brute forced back to existing.

I noticed that the input is not being treated any way before hashing. I'd remove all non-letter characters, and then lowercase everything before hashing to help with some unnecessary misses.

Some of the top items:

  hello world

Thanks to Y@Y for 4ef69019c65909ffbb470597e3c5afe05ea8a866a0d3b9f950f0bcf057924b52.
Another comment here as I got way too much excited in the other one, but this is genuinely so good man!!! KUDOS!

It actually provides a simple curl command. Oh boy, this does open up a few more ideas. I feel like my wall of text -> link shortener / blog and all other comments on that wall of text being comments themselves might be implemented & this does open up to a lot of possibilities

I actually got a vps of like 8 gigs 4 cores 500 gigs ssd for 3 months prepaid and I snatched it during a recurring deal.

If you want, i can transfer it to you or share half the resources or similar to you if this project ever needs one.

One of the most interesting things is that this (unlike my idea which was just a "proof" if it was possible in a more complex environment) actually does make it simple and for normal devs to build upon

You are mentioning scotty, and I am not sure if you mention scuttlebutt the protocol or as if scotty is some haskell web framework (sorry don't know haskell)

What are your thoughts on scuttlebutt or (nanotimestamps), I have it open source under the MIT license for anyone to build on top of it with.

Your project's really polished and I admire it but I would hope that you can look more at the decentralization side of things because one of the ideas I had which never got to fruition was that adding on top of it, we can just have a social media similar to nostr but without the relay mess that nostr has in many instances (or so I have heard)

I am curious as to what are some use cases you are thinking of it as I'd love to know your opinion on it!

Have a nice day man!

someone declared bankruptcy before me in the office style
I was very susprised to not be the first to enter a quotation by Nelson Rodrigues. Nice.
Fun idea. One potential issue: the same person writing the same text repeatedly will count more than once, so it'd be pretty trivial to spoil the rankings. (This is why we can't have nice things.)
This is great, but never seems to say that its an original thought always defaulting to: "Including you, 1 person had that thought already! First time was less than a minute ago, last time was less than a minute ago."

"You are absolutely right!"

Well, at least we know claude didn't hit the API yet :)

I was the first to state that, contrary to popular belief, "the quick brown fox did not jump over the fence"
Popular belief holds that the quick brown fox jumped over the lazy dog, not the fence.

  Including you, 2 persons had that thought already!
You guys know who you are
Neat idea! I love this kind of low-stakes online interactions, a bit like 1,000,000 checkboxes as well - makes me realize how many others there are out there and invokes a strange but nice feeling of community :)
I love it!

I typed "hello".

Of course, everyone else has thought of this. But what if I "type": 4358f43b660389eecd435dc2a5f5cee29786245cd2cff27bd4de0b3e8fd53b79

That's hilarious!

And also, "typing": echo "hello world" | curl -d @- https://subth.ink

Next step: embeddings and similarity.

"I am happy"

Including you, 7 persons had that thought already!

"I am sad"

Including you, 9 persons had that thought already!

I was the first one with "here be dragons"? come on
