Before spidering the site for offline reading, be aware:

Why not to Scihub?
xpe•1mo ago
Sci-Hub rules:

    1. You do not talk about Sci-Hub.
    2. You do NOT talk about Sci-Hub.
    3. If a download says "Stop," goes limp,
       or taps out, that download is over. 
    4. Only two tries per mirror. 
    5. One download at a time. 
    6. Shirt and shoes optional. 
    7. Downloads will continue until publicly funded
       research is widely distributed. 
    8. If this is your first time at Sci-Hub, you
       have to download something interesting,
       actually read at least part of it, learn
       something, and then fight ignorance and/or
       stupidity with it.

Wonder why. Did they confuse this with Maoist literature (Little Red Book)?

Hmm maybe, a blooper on their part

I just switched networks (wifi/mobile) and it worked, only that provider seems to block it

How does this stack up in 2025/6?
herodoturtle•1mo ago
redbook.io huh?

Some might argue the Red Book to be “NSA Trusted Networks” a.k.a the ugly red book that won't fit on the shelf.

About time for the 6th Edition, eh? What would folks include in it?

- Vector databases and hybrid search?

- Object storage for all the things? Lake houses. Parquet and beyond.

- Continuously materialized views? I'm not sure this one has made the splash but I think about Naiad (Materialize) and Noria (Readyset)

- NewSQL went mostly mainstream (Spanner wasn't included in the last one, but there's been more here with things like CockroachDB, TiDB, etc)

LLMs as DBs (if you squint hard enough)
kwillets•1mo ago
The object storage stuff is new, but it's mostly confirmed that the older architecture works. MPP with shared (S3) storage and everything above that on local SSD and compute delivers the best performance. Even Snowflake finally came out with "interactive" warehouses with this architecture.

Parquet, Iceberg, and other open formats seem good, but they may hit a complexity wall. There's already some inconsistency between platforms, eg with delete vectors.

Incremental view maintenance interests me as well, and I would like to see it more available on different platforms. It's ironic that people use dbt etc. to test every little edit of their manually coded delta pipelines, but don't look at IVM.

teleforce•1mo ago
Definitely they should include D4M and GraphQL [1],[2].

Not only D4M can cater for structured relational data, it's also suitable for non-structured and sparse data in spreadsheet, matrices and graph. It's essentially a generalization of SQL but for all things data.

There's also integration of D4M with SciDB [3].

Amazing: the website's index page has the book's index in it. While this makes perfect sense, it's a kind of a feature that is becoming rare in today's tech book websites which display all sorts of marketing fluff, social confirmations etc and not the structure of the book itself.
