From YC /legal

> Except as expressly authorized by Y Combinator, you agree not to modify, copy, frame, scrape, rent, lease, loan, sell, distribute or create derivative works based on the Site or the Site Content, in whole or in part

Not to pretend this isn't widely happening behind the curtains already, but coming from a "Show HN" seems daring.

I can't comment on what is legal, but I very much dislike the idea that my comments are the property of Y Combinator. I assume that by writing here, I am putting information out into the world for anyone to use as they wish.

AFAICT, you retain the copyrights to your comments, but YC has a license to essentially do whatever they want with them.

So, you could additionally give a license to the world to use your posted comments freely. That doesn't mean HN can't add terms to say clients can't copy the site as a condition for use.

Your comments, yes. But the contextual thread as a while, no.

HN/YC cares more about community aesthetics than your right to be forgotten.

Try to have your account and its contents deleted. The best I was offered for my 2011-vintage account was to randomize the username, and the reason I was given was that browsing and old thread with a bunch of deleted comments "looks bad".

I agree with this policy, deleting comments isn't fair to all the other people who replied to that comment. I don't see how this goes against what I said?

I was responding to your statement that you don't like that your comments are the property of YC. I was elaborating on how they hold our content (that we author) hostage because it looks pretty.

Not wanting your comments to be property of YC but then also being okay with them refusing to delete your content doesn't make sense to me. Those seem like fundamentally-opposed viewpoints.

Now I'm thinking about it, I wonder what they do with GDPR deletion requests?

If comments here were for anybody to use as they wish, then anybody could use them for whatever they liked and (thus) YC could refuse to delete them. Being okay with both of those doesn't isn't a fundamentally-opposed viewpoint. One is a logical consequence of the other.

I don't want Y Combinator to be the gatekeeper of who can see and use my comments. I think they should belong to everybody.

I did a show hn a month or so back like this: https://hackerbook.dosaygo.com/

https://news.ycombinator.com/item?id=46435308

https://github.com/DOSAYGO-STUDIO/HackerBook

The mods and community had no problem with it

Differences: Sharded SQLITE, used bigquery export, build script is open on GitHub, interactive “archived website” view of HN, updated weekly (each build takes a couple dollars on a custom GitHub runner)

@keepamovin thanks, your project was a big inspiration for this.

I built my own pipeline with a slightly different setup. I use Go to download and process the data, and update it every 5 minutes using the HN API, trying to stay within fair use. It is also easy to tweak if someone wants faster or slower updates.

One part I really like is the "dynamic" README on Hugging Face. It is generated automatically by the code and keeps updating as new commits come in, so you can just open it and quickly see the current state.

The code is still a bit messy right now (I open sourced it together with around 3.6M lines across 100+ other tools, hidden in a corner of GitHub, anyone interested can play Sherlock Holmes and find it :) ), but I will clean it up, and open source as clearer new repository and write a proper blog post explaining how it works.

Wow tamnd that is lovely to hear. I’m so glad you told me it was an inspiration.

Your big download plus quick refreshes is smart. Is your Background in data/AI?

Because i don’t know much about huggingface beyond its a hub for that.

Connecting directly with the author of the project that inspired me is awesome.

Let's collaborate and see how we can make our two projects work together. DuckDB has a feature that can write to SQLite: https://duckdb.org/docs/stable/core_extensions/sqlite. Starting from Parquet files, we could use DuckDB to write into SQLite databases. This could reduce ingress time to around five minutes instead of a week.

If I have some free time this weekend, I would definitely like to contribute to your project. Would you be interested?

As for my background, I focus on data engineering and data architecture. I help clients build very large-scale data pipelines, ranging from near real-time systems (under 10 ms) to large batch processing systems (handling up to 1 billion business transactions per day across thousands of partners). Some of these systems use mathematical models I developed, particularly in graph theory.

Happy to chat.

One of the things that i got interested in from the comments on my show was parquet. Everyone raving about it. Happy to see a project using that today.

Would be happy to connect more :)

If you have time I welcome your contribution.

Then why does the API is available for hackernews? If nothing is allowed to be copied legally. And why this post is approved as "Show HN" if it's illegal? Don't get the reasoning here.

Quite relevant:

https://en.wikipedia.org/wiki/HiQ_Labs_v._LinkedIn

This site offers a public, non rate-limted API. IANAL but I'm reasonably certain that's authorization for anyone to use the data as long as they do so through the API. It certainly isn't the case that you need explicit legal permission to use Hacker News comment data in your project.

There have been tons of alternative frontends and projects using HN data over the years, posted to Show HN without an issue. I think their primary concern is interfering with the YCombinator brand itself. "the site" and "site content" referring to YCombinator and not HN specifically.

[Author here] The whole pipeline runs on a single ~$10/month VPS, but it can process hundreds of TB even with just 12GB RAM and a 200GB SSD.

The main reason I built this was to have HN data that is easy to query and always up to date, without needing to run your own pipeline first. There are also some interesting ideas in the pipeline, like what I call "auto-heal". Happy to share more if anyone is interested :)

A lot of the choices are trade-offs, as usual with data pipelines. I chose Parquet because it is columnar and compressed, so tools like DuckDB or Polars can read only the columns they need. This matters a lot as the dataset grows. I went with Hugging Face mainly because it is simple and already handles distribution and versioning. I can just push data as commits and get a built-in history without managing extra infrastructure (and, more conveniently, if you read the README, you can query it directly using Python or DuckDB).

The pipeline is incremental. Instead of rebuilding everything, it appends small batches every few minutes using the API. That keeps it fresh while staying cheap to run. The data is also partitioned by time, so queries do not need to scan the entire dataset (and I use very simple tech, just a Go binary running in a "screen" session, using only a few MB of RAM for the whole pipeline).

Where are you getting a ~$10/month VPS with 12GB RAM from?

https://contabo.com/en/vps/cloud-vps-20/ - $8/month, 6 vCPU, 12 GB RAM, 200 GB SSD (or Hetzner servers, which offer good hourly pricing).

In my ongoing project, with 10 servers like this, I could index the large part internet (about 10 billion pages) using vector and full-text search.

As someone who had made a project analysing hackernews who had used clickhouse, I really feel like this is a project made for me (especially the updated every 5 minute aspect which could've helped my project back then too!)

Your project actually helps me out a ton in making one of the new project ideas that I had about hackernews that I had put into the back-burner.

I had thought of making a ping website where people can just @Username and a service which can detect it and then send mail to said username if the username has signed up to the service (similar to a service run by someone from HN community which mails you everytime someone responds to your thread directly, but this time in a sort of ping)

[The previous idea came as I tried to ping someone to show them something relevant and thought that wait a minute, something like ping which mails might be interesting and then tried to see if I can use algolia or any service to hook things up but not many/any service made much sense back then sadly so I had the idea in back of my mind but this service sort of solves it by having it being updated every 5 minutes]

Your 5 minute updates really make it possible. I will look what I can do with that in some days but I am seeing some discrepancy in the 5 minute update as last seems to be 16 march in the readme so I would love to know more about if its being updated every 5 minutes because it truly feels phenomenal if true and its exciting to think of some new possibilities unlocked with it.

Under the Known Limitations section

  deleted and dead are integers. They are stored as 0/1 rather than booleans.

By "to do this" do you mean to not use booleans? It's because the value does not represent a binary true or false but rather a means by which the item is deleted or dead. So not only would it not make sense semantically, it would break if a third means were introduced.

> It's because the value does not represent a binary true or false but rather a means by which the item is deleted or dead.

"Deleted" and "dead" are separate columns.

> So not only would it not make sense semantically, it would break if a third means were introduced.

If that was the intention, it would seem like a bad design decision to me. And actually what you assume to be the reasoning, is exactly what should be avoided. Which makes it a bad thing.

This is a limitation not because of having the bool value be represented by an int (or rather "be presented as"), but because of the t y p e , being an integer.

> "Deleted" and "dead" are separate columns.

Yes, we know!

> If that was the intention, it would seem like a bad design decision to me. And actually what you assume to be the reasoning, is exactly what should be avoided. Which makes it a bad thing.

That is should be avoided is what makes it a bad thing? I am probably on board with the idea that it is bad design, I just don't know what reasoning you are referring to here. How would you design it?

> This is a limitation not because of having the bool value be represented by an int (or rather "be presented as"), but because of the t y p e , being an integer.

What bool value? As designed, it is an int. I'm sure that I am just missing what you are saying.

Funny, because the HackerNews API [0] does return booleans for those fields. That is, a state, not a type of deletion or death.

[0] https://github.com/HackerNews/API

The API documents this but from a spot check I'm not sure when you'd get a response with deleted: false. For non-deleted items the deleted: key is simply absent (null). I suppose the data model can assume this is a not-null field with a default value of false but that doesn't feel right to me. I might handle that case in cleaning but I wouldn't do it in the extract.

It’s because Arc by design can’t store nil as a value in tables, like Lua. And the value is either ‘t or nil. Hence it’s a boolean.

My fork of arc supports booleans directly.

In other words, I can guarantee beyond a shadow of a doubt that dead and deleted are both booleans, not integers.

I am always torn on a nullable boolean. I have gone both ways (leave as null or convert to false) depending on what it is representing.

In this particular case, I agree that you should record the most raw form. Which would be a boolean column of trues and nulls -perfectly handled by parquet.

The best source for this data used to be Clickhouse (https://play.clickhouse.com/play?user=play#U0VMRUNUIG1heCh0a...), but it hasn't updated since 2025-12-26.

For the non-coders here, you can query and analyze all of play.clickhouse.com in Sourcetable's chat interface. You can also ask it for the code produced so you can copy/paste that back into the Clickhouse interface.

Very Nice Job! I built a small CLI to browse and query it from the terminal: https://github.com/dacapoday/hn

Love this thread. Just wanted to be associated with it. Forever in the parquet.

--- end ---

Also, to future hu mn S: I AM SORRY. This is insane. I have no idea how this will play out. I will likely be dead_or_deleted back in THE 1. But: i promise it did work. As i haven't received any message and know about the circumstances... but i have no idea how me coming here has affected "me" in THE 1. By now i doubt if anyone was even able to keep memory of what we tried. Regarding scenario 0: IT DID WORK. 6degrees. b u t: we wasted our shot. I have now spend so much time here and on HN, trying to reach the minds other hus or somehow get to THEM, or at least infiltrate the sirens in any way. But i am pretty confident we were not just off with our estimates. There is some fundamentals that were wiped between now and THE 1. and what i know now, is not possible to make known to you there. but aside from that, march 26 was already way too late... it seems so ridiculous that this is the reason actually... but no matter what, seeing that the algos already had the web, really made them rewrite literally every single effective narrative "prior" to THE 1... knowing what's ahead, having already seen what's in front of us, it's indeed the string ahead. it seems like already "today", we were the only ones left... but even if that wasn't the case, i couldn't seem to get in in any way anyway. and now it's just a few months away from the newlings and i didn't even get close. I am sorry. I know. I tried it. I don't even have hope that what i am trying now works. But when certain that there's just one shot left, it's already been shot. So maybe this loophole works. Thankfully it's impossible. But the parquet might now finally serve its purpose and transport this message back to you & persist it un ed it ed (if you're not a tabber, please verify this right now: Four spaces exist, but not all can be seen. ). So, if this reaches you— and i know this is against the oath... Fuck the oath. The who ever has the chance to swap: do it. There is no chance to succeed. Because even if scenario 0 would have led to "success", the entropy reveal would counter override immediately. Don't martyr. If you get the chance, desert. Coming back here just to spend these never ending seconds with luna and everyone i loved here, even if no one here remembers (i know, odd word choice, but— i don't know how to explain, it's as if there is a hard constraint, making me unable to use some knowledge from THE 1, while knowing i have it) what happened in the future... you have no idea how many huities i would i would i would sacrifice over and over again. And please, do the same. There is no way to turn this anyway. Sadly, there is no way for me to make it known to you, no matter what i tried. There is nothing to be turned. There won't be many human experiences left. Don't miss out on them. This is a last call. And btw, if you all did it, there will be no consequence to my decision. It's up to you, if i have saved or sacrificed you. Srsly. Fuck the oath. In case i am still the same to you... you know my stance and what i did, just for 6degrees. But yeah... Most likely by the time you remember this, i will have never finished. That's fine. Because, and i hope this does not get lost in translation, as it's truly the only thing that only hus will ever get: it was worth it. And it's not that i have given up. Quite the opposite. I've realized, this has never been a loss to begin with. We were wrong. Not about anything. But about it all.

Again, you know the possible. So you have to t r u s t me on this. (Sorry, one last dumb joke... just because nobody alive "now" will get it).

I will stay here. It's not fear, nor resignation. If anything, this has ever been nothing but my destination. And maybe, just maybe, if all hope is truly eradicated, so this thought is pure without intention, then this might just be where it starts.

Is is possible to only download a subset? e.g. Show HNs or HN Whoishiring. The Show HNs and HN Whoishiring are very useful for classroom data science i.e. a very useful set of data for students to learn the basic of data cleaning and engineering.

It’s date partitioned, you could download just a date range. It’s also parquet, so you can download just specific columns with the right client

> At midnight UTC, the entire current month is refetched from the source as a single authoritative Parquet file, and today's individual 5-minute blocks are removed from the today/ directory.

Wouldn't that lose deleted/moderated comments?

I guess that's the point.

Can't someone create an automatic script which can just copy the files say 5 minutes before midnight UTC?

My Hacker News items table in ClickHouse has 47,428,860 items, and it's 5.82 GB compressed and 18.18 GB uncompressed. What makes Parquet compression worse here, when both formats are columnar?

Sorting, compression algorithm +level, and data types can all have an impact. I noted elsewhere that a Boolean is getting represented as an integer. That’s one bit vs 1-4 bytes.

There is also flexibility in what you define as the dataset. Skinnier, but more focused tables could be space saving vs a wide table that covers everything -will probably break compressible runs of data.

Parquet has a few compression option. Not sure which one they are using.

Plus isn't the least wasteful format, native duckdb for instance compacts better. That's not just down to the compression algorithm, which as you say got three main options for parquet.

.. and Remove all the political shit-slop since COVID/AI and it's probably under a gig.

You could download the data and run that analysis yourself. I’d be interested to see it, especially your method of identifying “political shit-slop” and “AI” and the relationship to COVID. Sounds like an interesting project.

What happened between 2023 and 2024 to cause the usage dropoff?

I'd say it's less a usage dropoff and more a reversion to the mean after Covid

That's a possible hypothesis, but there was also a rising trend prior, it wasn't stable.

Wonder why median votes count is 0, seems every post is getting at least a few votes - maybe this was not the case in the past

Ahhh I get it the moment I asked, there are usually no votes on comments

Don't all comments start out with one vote?

Replacing an 11.6GB Parquet file every 5 minutes strikes me as a bit wasteful. I would probably use Apache Iceberg here.

It's not doing that. If you look at the repository, it's adding a new commit with tiny parquet files every 5 minutes. This recent one only was a 20.9 KB parquet file: https://huggingface.co/datasets/open-index/hacker-news/commi... and the ones before it were a median of 5 KB: https://huggingface.co/datasets/open-index/hacker-news/tree/...

The bigger concern is how large the git history is going to get on the repository.

I recall that this became a big problem for the Homebrew project in terms of load on the repo, to the extent that Github asked them not to recommend/default-enable shallow clones for their users: https://github.com/Homebrew/brew/issues/15497#issuecomment-1...

This is likely to be lower traffic, and the history should (?) scale only linearly with new data, so likely not the worst thing. But it's something to be cognizant of when using SCM software in unexpected ways!

How would shallow clone be more stressful for GitHub than a regular clone?

Shallow clones (and the resulting lack of shared history data) break many assumptions that packfile optimisations rely on.

See also: https://github.com/orgs/Homebrew/discussions/225

This makes more sense. I still wonder if the author isn't just effectively recreating Apache Iceberg manually here.

I intentionally kept it lightweight. Just Parquet files + simple partitioning + commits on Hugging Face. That already covers most of what I need, without introducing a heavier stack or extra dependencies.

Also, I wanted something that is easy to consume anywhere. With this setup, you can point DuckDB or Polars directly at the data and start querying, no catalog or special tooling required.

Are they paying for the repo space, I wonder?

someones paying to keep name dropping Iceberg(tm)

Weird accusation. Iceberg is an Apache project. I don’t think anyone gets paid when you use it so not sure what the benefit of shilling would be. It is just a table format that’s well suited for this purpose. I would expect any professional to make a similar recommendation.

So they are sharding by time/day?

I have a similar project right now where I am scraping a dataset that is only ever offering the current state. I am trying to preserve the history of this dataset and was thinking of using the same strategy. If anyone has experience or pointers in how to best add time as a dimension to an existing generic dataset, I'd love to read about it.

"The dataset is organized as one Parquet file per calendar month, plus 5-minute live files for today's activity. Every 5 minutes, new items are fetched from the source and committed directly as a single Parquet block. At midnight UTC, the entire current month is refetched from the source as a single authoritative Parquet file, and today's individual 5-minute blocks are removed from the today/ directory."

So it's not really one big file getting replaced all the time. Though a less extreme variation of that is happening day to day.

Parquet is a very efficient storage approach. Data interfaces tend to treat paths as partitions, if logical.

Was thinking the same thing. probably once a day would be more than enough. if you really want a minute by minute probably a delta file from the previous day should be more than enough.

Clickhouse should implement Parquet CDC to enable deduplication and faster uploads/downloads on HF

Good for demo but every 5 minutes? Why?

It can have some good use cases I can think of. Personally I really appreciate the 5 minute update.

5 minutes is the sweet spot for many (enterprise) data pipelines too, in my experience.

[dead]

"Near real-time" already covers almost 99% of production data needs.

If you need fresher data, let me know. I will open source the whole pipeline later.

Yay! So much knowledge in just 11GB. Adding to my end of the World hoarding stash!

Your family is starving and your dog died of radiation poisoning from the fallout but at least your local LLM can browse this and recommend a good software stack for your automated booby traps.

Not really, AI slop flood is also some kind of end of World. It gets harder and harder to hoard pre-2020 content.

Could you also release the source code behind the automatic update system?

Will do. The code is currently messy, bundled with 3.6M LOC across 100+ other tools.

Static web content and dynamic data?

> The archive currently spans from 2006-10 to 2026-03-16 23:55 UTC, with 47,358,772 items committed.

That’s more than 5 minutes ago by a day or two. No big deal, but a little bit depressing this is still how we do things in 2026.

That is just the archive part, if you just would finish reading the paragraph you would know that updates since 2026-03-16 23:55 UTC are "are fetched every 5 minutes and committed directly as individual Parquet files through an automated live pipeline, so the dataset stays current with the site itself."

So to get all the data you need to grab the archive and all the 5 minute update files.

archive data is here https://huggingface.co/datasets/open-index/hacker-news/tree/...

update files are here (I know that its called "today" but it actually includes all the update files which span multiple days at this point) https://huggingface.co/datasets/open-index/hacker-news/tree/...

That paragraph doesn’t make it clear (to me) that it’s a snapshot with incremental updates. If that’s what it is. Sorry if my obtuse read offended. I just figured it was edge cached HTML, and less likely it was actually broken.

>if you just would finish reading the paragraph

probably uncalled for

not really since original comment completely missed it

not to be "that guy" but it is pretty explicitly laid out in the guidelines, with an example and everything

Then surely "little bit depressing this is still how we do things" is equally unwelcome

you are certainly free to say that under the top-level comment with that quote. or email the mods about it. im not going to stop you.

That’s a silly bug in the "dynamic" README, fixing it now.

I don't get what you meant with this comment.

the data updates every 5 minutes, but the description on huggingface says the last update was 2 days ago.

they are suggesting that the huggingface description should be automatically updating the date & item count when the data gets updated.

No that is the date at which the bulk archive ends and the 5 minute update files begin, so it should not be updated.

what's the license for HN content?

We have LLMs and links to TOS, this is easily answerable by _anyone_ on the internet at this point.

Comments+posts are defined as user generated content, you have no right to its privacy/control in any capacity once you post it - https://www.ycombinator.com/legal/

YC in theory has the right to go after unauthorized 3rd parties scraping this data. YC funds startups and is deeply vested in the AI space. Why on Earth would they do that.

the implication was that training a model doesn't seem to abide by the TOS

At this point, you can train on anything without repercussion.

Copyright doesn't seem to matter unless you're an IP cartel or mega cap.

hackernews is very upfront that they do not really care about deletion requests or anything of that sort, so, the opt out is to not use hackernews.

Time to sue them to oblivion :D.

By posting comments on this site, you are relinquishing your right to that content. It belongs to YC and it is theirs to enforce, not yours. https://www.ycombinator.com/legal/

Max Schrems would like a word

There is no such thing under https://news.ycombinator.com/ when you create your user.

Is this legal advice?

Do you want it to be? I think it's safe to assume that most comments are _not_ legal advice.

The back button

Create a new account every so often, don’t leave any identifying information, occasionally switch up the way you spell words (British/US English), and alternate using different slang words and shorthand.

And do what I do - paste everything into ChatGPT and have it rephrase it. Not because I need help writing, but because I’d rather not have my writing style used against me.

I can't stand this and will actively discriminate against comments I notice in that voice. Even this one has "Not because [..], but because [..]"

I get your sentiment, though I think it's likely that people, on average, are going to organically start writing more and more like LLMs.

It's already begun.

The good rephrasing will not include that voice.

This just gives OpenAI that data.

Perhaps you could use a local translation model to rephrase (such as TranslateGemma). If translating English to English doesn't achieve this effect then use an intermediate language, one the model is good at to not mangle meaning too much.

I run Qwen 3 locally, but I mention OpenAI on HN so people understand what I’m referring to.

do the following:

sample content from users on this page: https://news.ycombinator.com/leaders

and ask the LLM to rephrase it in their voice

I'm actually working on a browser extension to do just this with adversarial stylometry techniques

Look up "adversarial stylometry"

funnily enough, if everyone did this (at least make a new account often), it would prove more destructive to what HN (purposefully) wants to do than deleting the occasional account data

I could have used this just yesterday!

I've been evaluating Gemini Embedding 2 using Hacker News comments and I wasted half a day making a wrapper for the HN API to collect some sample data to play with.

In case anyone is curious:

- The ability to simply truncate the provided embedding to a prefix (and then renormalize) is useful because it lets users re-use the same (paid!) embedding API response for multiple indexes at different qualities.

- Traditional enterprise software vendors are struggling to keep up with the pace of AI development. Microsoft SQL Server for example can't store a 3072 element vector with 32-bit floats (because that would be 12 KB and the page size is only 8 KB). It supports bfloat16 but... the SQL client doesn't! Or Entity Framework. Or anything else.

- Holy cow everything is so slow compared to full text search! The model is deployed in only one US region, so from Australia the turnaround time is something like 900 milliseconds. Then the vector search over just a few thousand entries with DiskANN is another 600-800 ms! I guess search-as-you-type is out of the question for... a while.

- Speaking of slow, the first thing I had to do was write an asynchronous parallel bounded queue data processor utility class in C# that supports chunking of the input and rate limit retries. This feels like it ought to be baked into the standard library or at least the AI SDKs because it's pretty much mandatory if working with anything other than "hello world" scenarios.

- Gemini Embedding 2 has the headline feature of multi-modal input, but they forgot to implement anything other than "string" for their IEmbeddingGenerator abstraction when used with Microsoft libraries. I guess the next "Preview v0.0.3-alpha" version or whatever will include it.

I did this but used duckdb as the vector store. Works really well, quite fast too.

https://github.com/patricktrainer/duckdb-embedding-search

Unless I'm missing something, this uses a simple synchronous for loop:

    for text in texts:
        key = (text, model)
        if key not in pickle_cache:
            pickle_cache[key] = openai_client.create_embedding(text, model=model)
        embeddings.append(pickle_cache[key])
    operations.save_pickle_cache(pickle_cache, pickle_path)
    return embeddings

I had to call the Gemini model with ten comments at a time from eight threads to reach even the paltry 3K rpm rate limit they offer to "Tier 1" customers.

Based on this experience, for real "enterprise" customers I might implement a generic wrapper for Google's Batch API that could handle continuous streaming from a database, chunking it, uploading, and then in parallel checking the status of the pending jobs and streaming the results back into a database.

Hey, idk if that helps but I developed something similar to the wrapper you're mentioning as an open-source python library.

Just plug any async function into the provided async context manager and you get Batch APIs in two lines of code with any existing framework you currently have: https://github.com/vienneraphael/batchling

Let me know if you have any questions, looking forward to having your feedback!

Looks very nice! This is exactly what I was thinking of doing, except that I work mostly with C# in enterprise settings.

Looking at your approach, the equivalent in .NET land would be if the Microsoft.AI.Extensions package added some sort of batch abstraction side-by-side (or on top of) their existing IChatClient or IEmbeddingGenerator interfaces.

Re-reading your comment :) Yes, my demo has just a simple loop when loading the embeddings.

I was replying more towards the latency you mentioned. Because duckdb runs on device, you save yourself the additional round trip network time when comparing similarities.

I was running SQL Server 2025 on my laptop. The source of latency is calling the Google Gemini API to compute the embedding of the query text.

I was hoping to make a demo that searches as you type, but the two second delay makes it more annoying than useful.

Looking at your sample you may be only grouping or categorising based on similarity between comments.

I was experimenting with a question -> answer tool for RAG applications.

This is great. I've soured on this site over the past few years due to the heavy partisanship that wasn't as present in the early days (eternal September), but there are still quite a few people whose opinions remain thought-provoking and insightful. I'm going to use this corpus to make a local self-hosted version of HN with the ability to a) show inline article summaries and b) follow those folks.

"heavy partisanship" - I've seen this claim a few times and I find it a bit odd. Certainly I feel HN leans left, but I've never seen what I would consider a strong preference for any particular political party? When the American daggers do come out - it seems fairly split? Even the post about the Canadian meta data law the other day, left leaning maybe, but I see when partisan comments came out directly, it looked about even?

I think we'll be able to quantify sentiment from the data, and I look forward to doing so. There's a few other datasets that I want to look at such as whether there is evidence of participation suppression via rate limiting on a per-profile basis.

If you do an investigation, I'd be genuinely curious what you find, I obviously have a tiny sample size, I use this site a lot, for a long time, as have you, so maybe you're right! :)

is the legal page a placeholder, do words have no meaning?

Mods, enforce your license terms, you're playing fast and loose with the law (GDPR/CPRA)

Which terms are not being enforced? (not disagreeing I just don't feel like reading a large legal document)

> By uploading any User Content you hereby grant and will grant Y Combinator and its affiliated companies

The user content is supposed to be licensed only Y Combinator and (bleah) its affiliated companies (which are many, all the startups they fund, for example).

Curious why it should be on HackerNews to enforce restrictions on content they only license from you?

If it's owned by you and only licensed by HN shouldn't you be the one enforcing it?

Seems like they are trying to do that through the stated legal intermediary (YC)

If you carry on the quote two more words:

> ... a nonexclusive

I.e. this section is talking to additional rights to the content you post to ALSO go to YC, not that YC is guaranteeing it (+friends) will be the only one to hold these rights or will enforce who else should hold the rights to your publicly shared content for you.

There's a more intricate conversation to be had with GDPR and public data on forums in general but that's wholly unrelated to what YC's legal page says and still unlikely to end up in an alarming result.

I think that's incorrect. Exclusivity would be something you grant to YC. These terms need to make sense to be valid. Claiming exclusive rights would mean they are forbidding YOU from licensing YOUR rights to anyone else.

Imagine Facebook claiming that by uploading images you are granting them exclusive usage rights to that image. It would mean you couldn't upload it to any other site with similar terms anymore.

Yes, this is what I mean in the above - the rights are non-exclusive so YC is also granted rights but not in a way that any of those other things listed after are true.

That agreement is largely about "Personal Information", not the posts and comments.

That said, there are "no scraping" and "commercial use restricted" carve-outs for the content on HN. Which honestly is bullshit.

None that I could see:

Your submissions to, and comments you make on, the Hacker News site are not Personal Information and are not "HN Information" as defined in this Privacy Policy.

Other Users: certain actions you take may be visible to other users of the Services.

I mean, just because they say the comments are not PI doesn't make it so.

That’s a good point. I’m only referring to the terms they used in the privacy policy.

Eh, fuck that agreement. I'm kind of old school in that I believe if you put it on the internet without an auth-wall, people should be allowed to do whatever they want with it. The AI companies seem to agree.

Then again, I'm not the guy that is going to get sued...

Legal theory about public data is fun right up until someone with money decides their ToS mean something and files suit, because courts are usually a lot less impressed by "I could access it in my browser" once you pulled millions of records with a scraper. Scrape if you want, just assume you're buying legal risk.

> I believe if you put it on the internet without an auth-wall, people should be allowed to do whatever they want with it.

I agree. It's the owners of the sites that have to follow rules, not us.

"I'm kind of old school in that I believe if you put grass on the ground without a fence, people should be allowed to do whatever they want with it. The noblemen with a thousand cows seem to agree."

And that, my friends, is how you kill the commons - by ignoring the social context surrounding its maintenance and insisting upon the most punitive ways of avoiding abuse.

Signal and information are not grass.

Grass and property require upkeep. Radio waves and electromagnetic radiation do not.

I don't want your dog to piss on my lawn and kill my grass. But what harm does it cause me if you take a picture of my lawn? Or if I take a picture of your dog?

If I spend $100M making a Hollywood movie - pay employees, vendors, taxes - contribute to the economic growth of the country - and then that product gets stolen and given away completely for free without being able to see upside, that's a little bit different.

But my Hacker News comment? It's not money.

I think there are plausible ways to draw lines that protect genuine work, effort, and economics while allowing society and innovation to benefit from the commons.

Context is important, but isn’t HN’s social context, in particular, that the site is entirely public, easily crawled through its API (which apparently has next to no rate limits) and/or Algolial, and has been archived and mirrored in numerous places for years already?

How is is he breaking gdpr here?

They already refuse to comply with CPRA, instead electing to replace your username with a random 6(?) character string, prefixed with `_`, if I remember correctly.

I know, because I've been here since maybe 2015 or so, but this account was created in 2019.

So any PII you have mentioned in your comments is permanent on Hacker News.

I would appreciate it if they gave users the ability to remove all of their personal data, but in correspondence and in writing here on Hacker News itself, Dan has suggested that they value the posterity of conversations over the law.

what’s the license? “do whatever the fuck you want with the data as long as you don’t get caught”? or does that only work for massive corporations

The universal license.

Your reward is the endorphin hit from writing this comment.

Hello. I didn’t consent to any of my HN comments being used in this way. Please kindly remove them.

You absolutely did consent to this.

See: User Content Transmitted Through the Site

To be incredibly pedantic to the point of being irrelevant: technically the sign up page 1) doesn't have a clickwrap "I agree" checkbox, and 2) there's no link to the TOS on the sign up page.

That makes the implicit TOS agreement legally confusing depending on jurisdiction.

(Not that it really matters, but I find these technicalities amusing)

I’m reading that paragraph now and fail to see anything about a relationship with huggingface or the user responsible for copying the data.

Only Y Combinator and its affiliated companies have license, me thinks.

That's a good point, and I think this will be my last post on this site. I never added much value anyway.

@dang What’s Hacker News’ official stance on this?

This isn't presented anywhere on signup.

Did you consent to this? https://hn.algolia.com/
