Don't miss how this works. It's not a server-side application - this code runs entirely in your browser using SQLite compiled to WASM, but rather than fetching a full 22GB database it instead uses a clever hack that retrieves just "shards" of the SQLite database needed for the page you are viewing.

I watched it in the browser network panel and saw it fetch:

  https://hackerbook.dosaygo.com/static-shards/shard_1636.sqlite.gz
  https://hackerbook.dosaygo.com/static-shards/shard_1635.sqlite.gz
  https://hackerbook.dosaygo.com/static-shards/shard_1634.sqlite.gz
As I paginated to previous days.

It's reminiscent of that brilliant SQLite.js VFS trick from a few years ago: https://github.com/phiresky/sql.js-httpvfs - only that one used HTTP range headers, this one uses sharded files instead.

The interactive SQL query interface at https://hackerbook.dosaygo.com/?view=query asks you to select which shards to run the query against, there are 1636 total.

A read-only VFS doing this can be really simple, with the right API…

This is my VFS: https://github.com/ncruces/go-sqlite3/blob/main/vfs/readervf...

And using it with range requests: https://pkg.go.dev/github.com/ncruces/go-sqlite3/vfs/readerv...

And having it work with a Zstandard compressed SQLite database, is one library away: https://pkg.go.dev/github.com/SaveTheRbtz/zstd-seekable-form...

Your page is served over sqlitevfs with Range queries? Let's try this here.

this does not caches the data right? it would always fetch from network? by any chance do you know of solution/extension that caches the data it would make it so much more efficient.

A recent change is I added date spans to the shard checboxes on query view so it's easier to zero dates you want if you have that in mind. Because if your copy isn't local all those network pulls take a while.

The sequence of shards you saw when you paginated to days is faciliated by the static-manifest which maps HN item ID ranges to shards, and since IDs are increasing and a pretty good proxy of time (a "HN clock"), we can also map the shards that we cut up by ID to the time spans their items cover. An in memory table sorted by time is created from the manifest on load so we can easily look up which shard we need when you pick a day.

Funnily enough, this system was thrown off early on by a handful of "ID/timestamp" outliers in the data: items with weird future timestamps (offset by a couple years), or null timestamps. To cleanse our pure data from this noise, and restore proper adjacent-in-time shard cuts we just did a 1/99 percentile grouping and discarded the outliers leaving shards with sensible 'effective' time spans.

Sometimes we end up fetching two shards when you enter a new day because some items' comments exist "cross shard". We needed another index for that and it lives in cross-shard-index.bin which is just a list of 4-byte item IDs that have children in more than 1 shard (2-bytes), which occurs when people have the self-indulgence to respond to comments a few days after a post has died down ;)

Thankfully HN imposes a 2 week horizon for replies so there aren't that many cross-shard comments (those living outside the 2-3 days span of most, recent, shards). But I think there's still around 1M or so, IIRC.

Thanks! I'm glad you enjoyed the sausage being made. There's a little easter egg if you click on the compact disc icon.

And I just now added a 'me' view. Enter your username and it will show your comments/posts on any day. So you can scrub back through your 2006 - 2025 retrospective using the calendar buttons.

Is there anything more production grade built around the same idea of HTTP range requests like that sqlite thing? This has so much potential

Humphrey

a day ago

Yes — PMTiles is exactly that: a production-ready, single-file, static container for vector tiles built around HTTP range requests.

I’ve used it in production to self-host Australia-only maps on S3. We generated a single ~900 MB PMTiles file from OpenStreetMap (Australia only, up to Z14) and uploaded it to S3. Clients then fetch just the required byte ranges for each vector tile via HTTP range requests.

It’s fast, scales well, and bandwidth costs are negligible because clients only download the exact data they need.

PMTiles is absurdly great software.

Humphrey

I know right! I'd never heard of HTTP Range requests until PMTiles - but gee it's an elegant solution.

keepamovin

13 hours ago

Hadn't seen PMTiles before, but that matches the mental model exactly! I chose physical file sharding over Range Requests on a single db because it felt safer for 'dumb' static hosts like CF. - less risk of a single 22GB file getting stuck or cached weirdly. Maybe it would work

hyperbolablabla

12 hours ago

My only gripe is that the tile metadata is stored as JSON, which I get is for compatibility reasons with existing software, but for e.g. a simple C program to implement the full spec you need to ship a JSON parser on top of the PMTiles parser itself.

jtbaker

Look into using duckdb with remote http/s3 parquet files. The parquet files are organized as columnar vectors, grouped into chunks of rows. Each row group stores metadata about the set it contains that can be used to prune out data that doesn’t need to be scanned by the query engine. https://duckdb.org/docs/stable/guides/performance/indexing

LanceDB has a similar mechanism for operating on remote vector embeddings/text search.

It’s a fun time to be a dev in this space!

There was a UK government GitHub repo that did something interesting with this kind of trick against S3 but I checked just now and the repo is a 404. Here are my notes about what it did: https://simonwillison.net/2025/Feb/7/sqlite-s3vfs/

I also have a locally cloned copy of that repo from when it was on GitHub. Same latest commit as your copy of it.

From what I see in GitHub in your copy of the repo, it looks like you don’t have the tags.

Do you have the tags locally?

If you don’t have the tags, I can push a copy of the repo to GitHub too and you can get the tags from my copy.

Doing all this in an hour is such a good example of how absurdly efficient you can be with LLMs.

socialcommenter

From reading the TIL, it doesn't appear as if Simon used LLM for a large portion of what he did; only the initial suggestion to check the archive, and the web tool to make his process reproducible. Also, if you read the script from his chat with Claude code, the prompt really does the heavy lifting.

Sure, the LLM fills in all the boilerplate and makes an easy-to-use, reproducible tool with loads of documentation, and credit for that. But is it not more accurate to say that Simon is absurdly efficient, LLM or sans LLM? :)

Nothing smart with HTTP range requests yet - I have https://lite.datasette.io which runs the full Python server app in the browser via WebAssembly and Pyodide but it still works by fetching the entire SQLite file at once.

gdal vsis3 dynamically fetches chunks of rasters from s3 using range requests. It is the underlying technology for several mapping systems.

There is also a file format to optimize this https://cogeo.org/

ericd

a day ago

This is somewhat related to a large dataset browsing service a friend and I worked on a while back - we made index files, and the browser ran a lightweight query planner to fetch static chunks which could be served from S3/torrents/whatever. It worked pretty well, and I think there’s a lot of potential for this style of data serving infra.

This is pretty much well what is so remarkable about parquet files; not only do you get seekable data, you can fetch only the columns you want too.

I believe that there are also indexing opportunities (not necessarily via eg hive partitioning) but frankly - am kinda out of my depth pn it.

The GitHub page is no longer available, which is a shame because I'm really interested in how this works.

How was the entirety of HN stored in a single SQLite database? In other words, how was the data acquired? And how does the page load instantly if there's 22GB of data having to be downloaded to the browser?

keepamovin

You can see it now, forgot to make it public.

- 1. download_hn.sh - bash script that queries BigQuery and saves the data to *.json.gz

- 2. etl-hn.js - does the sharding and ID -> shard map, plus the user stats shards.

- 3. Then either npx serve docs or upload to CloudFlare Pages.

The ./toool/s/predeploy-checks.sh script basically runs the entire pipeline. You can do it unattended with AUTO_RUN=true

I use the Mudita Kompakt specifically cause it allows sideloading so I can still have a few extras. Right now I have Kiwix and Libby. It works really well.

I have a $10 a month plan from US cellular with only 2gigs so I try to keep everything offline that I can.

Honestly it's mostly the news... so I draw the line at browser, I'll never install a browser, that's basically something I can do when I sit down at a PC. I read quite a bit and I like to have the ability to look up a word or a historical event or some reference from something I read using Kiwix and it's been great for that, just needed to add a 512gb micro sd card. And Libby I just use at the gym when I'm on the treadmill.

Similar to Single-page applications (SPA), single-table application (STA) might become a thing. Just a shard a table on multiple keys and serve the shards as static files, provided that the data is Ok to share, similar to sharing static html content.

do you mean single database? it'd be quite hard if not impossible to make applications using a single table (no relations). reddit did it though, they have a huge table of "things" iirc.

mburns

That is a common misconception.

> Next, we've got more than just two tables. The quote/paraphrase doesn't make it clear, but we've got two tables per thing. That means Accounts have an "account_thing" and an "account_data" table, Subreddits have a "subreddit_thing" and "subreddit_data" table, etc.

And the important lesson from that the k/v-like aspect of it. That the "schema" is horizontal (is that a thing?) and not column-based. But I actually only read it on their blog IIRC and never even got the full details - that there's still a third ID column. Thanks for the link.

Paul-E

a day ago

That's pretty neat!

I did something similar. I build a tool[1] to import the Project Arctic Shift dumps[2] of reddit into sqlite. It was mostly an exercise to experiment with Rust and SQLite (HN's two favorite topics). If you don't build a FTS5 index and import without WAL (--unsafe-mode), import of every reddit comment and submission takes a bit over 24 hours and produces a ~10TB DB.

SQLite offers a lot of cool json features that would let you store the raw json and operate on that, but I eschewed them in favor of parsing only once at load time. THat also lets me normalize the data a bit.

I find that building the DB is pretty "fast", but queries run much faster if I immediately vacuum the DB after building it. The vacuum operation is actually slower than the original import, taking a few days to finish.

You could check out SQLite's auto_vacuum which reclaims space without rebuilding the entire db https://sqlite.org/pragma.html#pragma_auto_vacuum

Paul-E

21 hours ago

I haven't tested that, so I'm not sure if it would work. The import only inserts rows, it doesn't delete, so I don't think that is the cause of fragmentation. I suspect this line in the vacuum docs:

> The VACUUM command may change the ROWIDs of entries in any tables that do not have an explicit INTEGER PRIMARY KEY.

means SQLite does something to organize by rowid and that this is doing most of the work.

Reddit post/comment IDs are 1:1 with integers, though expressed in a different base that is more friendly to URLs. I map decoded post/comment IDs to INTEGER PRIMARY KEYs on their respective tables. I suspect the vacuum operation sorts the tables by their reddit post ID and something about this sorting improves tables scans, which in turn helps building indices quickly after standing up the DB.

simonw

a day ago

One interesting feature of DuckDB is that it can run queries against HTTP ranges of a static file hosted via HTTPS, and there's an official WebAssembly build of it that can do that same trick.

So you can dump e.g. all of Hacker News in a single multi-GB Parquet file somewhere and build a client-side JavaScript application that can run queries against that without having to fetch the whole thing.

You can run searches on https://lil.law.harvard.edu/data-gov-archive/ and watch the network panel to see DuckDB in action.

In that case, then using duckdb might be even more performant than using what we’re doing here.

DuckDB is an open-source column-oriented Relational Database Management System (RDBMS). It's designed to provide high performance on complex queries against large databases in embedded configuration.

It has transparent compression built-in and has support for natural language queries. https://buckenhofer.com/2025/11/agentic-ai-with-duckdb-and-s...

"DICT FSST (Dictionary FSST) represents a hybrid compression technique that combines the benefits of Dictionary Encoding with the string-level compression capabilities of FSST.

It is very similar to SQLite in that it can run in-process and store its data as a file.

It's different in that it is tailored to analytics, among other things storage is columnar, and it can run off some common data analytics file formats.

Pretty neat project. I never thought you could do this in the first place, very much inspiring. I've made a little project that stores all of its data locally but still runs in the browser to protect against take downs and because I don't think you should store your precious data online more than you have to, eventually it all rots away. Your project takes this to the next level.

While I suspect DuckDB would compress better, given the ubiquity of SQLite, it seems a fine standard choice.

peheje

the data is dominated by big unique TEXT columns, unsure how that can much compress better when grouped - but would be interesting to know

3eb7988a1663

5 hours ago

I was thinking more the numeric columns which have pre-built compression mechanisms to handle incrementing columns or long runs of identical values. For sure less total data than the text, but my prior is that the two should perform equivalently on the text, so the better compression on numbers should let duckdb pull ahead.

I had to run a test for myself, and using sqlite2duckdb (no research, first search hit), and using randomly picked shard 1636, the sqlite.gz was 4.9MB, but the duckdb.gz was 3.7MB.

The uncompressed sizes favor sqlite, which does not make sense to me, so not sure if duckdb keeps around more statistics information. Uncompressed sqlite 12.9MB, duckdb 15.5MB

Not the author here. I’m not sure about DuckDB, but SQLite allows you to simply use a file as a database and for archiving, it’s really helpful. One file, that’s it.

DuckDB does as well. A super simplified explanation of duckdb is that it’s sqlite but columnar, and so is better for analytics of large datasets.

The schema is this: items(id INTEGER PRIMARY KEY, type TEXT, time INTEGER, by TEXT, title TEXT, text TEXT, url TEXT

Doesn't scream columnar database to me.

kristianp

a day ago

I tried "select * from items limit 10" and it is slowly iterating through the shards without returning. I got up to 60 shards before I stopped. Selecting just one shard makes that query return instantly. As mentioned elsewhere I think duckdb can work faster by only reading the part of a parquet file it needs over http.

I was getting an error that the users and user_domains tables aren't available, but you just need to change the shard filter to the user stats shard.

Doesn't `LIMIT` just limit the amount of rows returned, rather than the amount read & processed?

SQLite

10 hours ago

That depends on the query. SQLite tries to use LIMIT to restrict the amount of reading that it does. It is often successful at that. But some queries, by their very nature, logically require reading the whole input in order to compute the correct answer, regardless of whether or not there is a LIMIT clause.

lucb1e

18 hours ago

That's what it does, but if I'm not mistaken (at least in my experience with MariaDB) it'll also return immediately once it ran up to the limit and not try to process further rows. If you have an expensive subquery in the SELECT (...) AS `column_name`, it won't run that for every row before returning the first 10 (when using LIMIT 10) unless you ORDERed BY that column_name. Other components like the WHERE clause might also require that it reads every row before finding the ten matches. So mostly yes but not necessarily

faxmeyourcode

The limit clause isn't official/standard ansi sql, so it's up to the rdbms to implement. Your assumption is true for bigquery (infamously) but not true for things like snowflake, duckdb, etc.

Similar in spirit to a recent tool I recently posted Show HN on, https://exopriors.com/scry. You can use Claude Code to SQL+vector query HackerNews and many other high quality public commons sites, exceptionally well-indexed and usually 5+ minute query timeout limits, so you can run seriously large research queries, to rapidly refine your worldview (particular because you can do easily to EXHAUSTIVE exploration).

Unfortunately even the videos that do contain helpful imagery are still dominated by huge sections of low entropy.

For example, one of the most useful applications of video over text is appliance or automotive repair, but the ideal format would be an article interspersed with short video sections, not a video with a talking head and some ~static shaky cam taking up most of the time as the individual drones on about mostly unrelated topics or unimportant details yet you can’t skip past it in case there is something actually pertinent covered in that time.

Ay, there's the rub. Professional video makes tend to be pushed into making videos for a more general audience, and niche topics are left to first-timers who haven't developed video-making skills and (tend to) go on and on.

I've produced a few videos, and I was shocked at how difficult it was to be clear. I have the same problem with writing, but at least it's restricted in a way video making isn't. There's so many ways to make a video about something, and most of them are wrong!

Average high quality 1080p60 video has bitrate of 5Mbps, which is equivalent to 120k English words per second. With average English speech being 150wpm, we end up with text being 50 thousand times more space efficient.

I could also summarize it with an llm. With pandoc or typst I can convert to single column or mult column pdf to print or watch on tv or my smart glasses. If I strip the vowels and make the font smaller I can fit more!

One could convert the Markdown/PDF to a very long image first with pandoc+wkhtml, then use ffmpeg to crop and move the viewport slowly over the image, this scrolls at 20 pixels per second for 30s - with the mpv player one could change speed dynamically through keys.

ffmpeg -loop 1 -i long_image.png -vf "crop=iw:ih/10:0:t*20" -t 30 -pix_fmt yuv420p output.mp4

Alternatively one could use a Rapid Serial Visual Presentation / Speedreading / Spritz technique to output to mp4 or use dedicated rsvp program where one can change speed.

One could also output to a braille 'screen'.

Scrolling mp4 text on the the TV or Laptop to read is a good idea for my mother and her macula degeneration, or perhaps I should make use of an easier to see/read magnification browser plugin tool.

Can be nice to pull a raw transcript and have it formatted as HTML (formatting/punctuation fixes applied).

Best locally of course to avoid “I burned a lake for this?” guilt.

yes, yt-dlp can download the transcript, and if it's not available i can get the audio file and run it through parakeet locally.

Site does not load on Firefox console error says 'Uncaught (in promise) TypeError: can't access property "wasm", sqlite3 is null'

Guess its common knowledge that SharedArrayBuffer (SQLite wasm) does not work with FF due to Cross-Origin Attacks (i just found out ;).

Once the initial chunk of data loads the rest load almost instantly on Chrome. Can you please fix the GitHub link (current 404) would like to peak at the code. Thank you!

Strange now the first few days load (getting a new error) 'Ignoring inability to install OPFS sqlite3_vfs: Cannot install OPFS: Missing SharedArrayBuffer and/or Atomics. The server must emit the COOP/COEP response headers to enable those. See https://sqlite.org/wasm/doc/trunk/persistence.md#coop-coep'

But when go back to the 26th none of the shards will load, error out.

Using Windows 11, FF 146.0.1

Since you tested it seems its just a me problem and thanks for fixing the GitHub link

No I've seen that error too, on Safari. I think it's related to the wasm being sent with wrong headers. CF pages _headers file should be ensuring correctness. Can you try busting your cache (or wait for a new Dec 29 Data dump version coming in a couple minutes), or from incognito to see if that fixes the issue? It's possible an earlier version had stale headers or sth. Idk.

Wonder if you could turn this into a .zim file for offline browsing with an offline browser like Kiwix, etc. [0]

I've been taking frequent "offline-only-day" breaks to consolidate whatever I've been learning, and Kiwix has been a great tool for reference (offline Wikipedia, StackOverflow and whatnot).

Fixed now. Forgot to make public. I also added a script:

To let you download the entire site over HTTPS so you don't need to "build it" by running the pipeline.

That way it's truly offline.

You mean like stuff ranked per year?

Is it a thing that the design is almost unusable on a mobile phone? The tech making this possible is beyond cool, but it's just presented in such a brutal way for phone users, even though fixing it would be super simple.

Just following the ordinary guidelines when doing responsive designs, like increasing the text size and sizes of buttons and inputs, so my fat fingers don't missklick every other try. HN has gotten better, but is still below average, hence why I thought it was some kind of aesthetic choice.

It's really a shame that comment scores are hidden forever. Would the admins consider publishing them after stories are old enough that voting is closed? It would be great to have them for archives and search indices and projects like this.

I wrote to hn@ and asked for this as a feature request:

"1. Delayed Karma Display. I understand why comment karma was hidden. I don't see the harm in un-hiding karma after some time. If not 24 hours, then 72-168 hours. This would help me read through threads with 1300 comments."

This was last January. While I asked for a few more features, it is the only one that seems essential as HN grows with massive threads.

They're referring to scores on individual COMMENTS - this information isn't available via the HN Firebase API.

The only way you could theoretically extract everyone's comment scores (at least the top level ones) would be like this if you're a complete madman:

1. Wait 48 hours so the article is effectively dead

2. Post a new comment using an account called ThePresident

3. Create a swarm of a thousand shill user accounts called Voter1, Voter2, etc.

4. Use a single account at a time and upvote ThePresident

5. Recheck the page to see if ThePresident has moved above a user(s) post

6. Record the score for that user and assign it to the tracked story's history

7. Repeat from (4)

I know that! I have a collaborative project to make it sort of available.

But the idea I have is not like that at all - it's much nicer on everyone's ethics. Stay tuned! :)

Did anyone get a copy of this before it was pulled? If GitHub is not keen, could it be uploaded to HuggingFace or some other service which hosts large assets?

I have always known I could scrape HN, but I would much rather take a neat little package.

dspillett

Is there a public dump of the data anywhere that this is based upon, or have they scraped it themselves?

Such as DB might be entertaining to play with, and the threadedness of comments would be useful for beginners to practise efficient recursive queries (more so than the StackExchange dumps, for instance).

keepamovin

Yes, you can see the download HN bash script in the repository now that simply extract the data to your local machine from BigQuery and saves it as a series of gzip JSON files

It would be nice for the thread pages to show a comment count.

Yes, because comments in a thread can span shards. It’s just a bit too heavy to add comment counts of an entire thread. So I give a low bound ha ha

Is this updated regularly? 404 on GitHub as the other comment.

With all due respect it would be great if there is an official HN public dump available (and not requiring stuff such as BigQuery which is expensive).

The BQ dataset is only ~17GB and the free tier of BQ lets you query 1TB per month. If you're not doing select * on every query you should be able to do a lot with that.
