Backing up Spotify annas-archive.li/blog, 2025-12-20, Discuss on Hacker News We backed up Spotify (metadata and music files). It’s distributed in bulk torrents (~300TB), grouped by popularity. This release includes the largest publicly available music metadata database with 256 million tracks and 186 million unique ISRCs. It’s the world’s first “preservation archive” for music which is fully open (meaning it can easily be mirrored by anyone with enough disk space), with 86 million music files, representing around 99.6% of listens.

Wake up babes, the most wonderful thing has finally happened.

Also wrote a blog post that explains the proof in a shorter format and with less formality

Signature schemes you've never heard about - Kobi's blog An exploration of some interesting signature schemes!

Wrote about a few interesting ones I’ve seen:
• Locally verifiable signatures, where you want to know a message from a set is signed
• Linear subspace signatures, where you can non interactively derive signatures for every vector in a subspace

Per lu descarregar youtube, faig servir el MeTube al server, però crec que no té per fer seguiment automàtic.
Com a punt positiu del muntatge, destacaria poder veure sèries no disponibles a les cada una de les plataformes d'streaming (o sèries que treuen de la carta quan les estavez veient).

Per si servís, s'engega tot en un docker compose, així només cal una sola comanda: github.com/arnaucube/co...
Però entenc el que dius de massa feina, per arribar al docker compose vaig estar setmanes de prova i error 😅

Podcasts: amb la app AntennaPod.
Música: torrent + SoulSeek (tots dos dins una raspberrypi), i ho pots servir amb Jellyfin als diversos dispositius de casa. I fora de casa: targeta microSD de 256gb al mòbil (o a un DAP).
(el sistema de raspberry+torrent+jellyfin serveix també per pelis i sèries)

REFHE: Fully Homomorphic ALU We present a fully homomorphic encryption scheme which natively supports arithmetic and logical operations over large "machine words", namely plaintexts of the form $\mathbb{Z}_{2^n}$ (e.g. $n=64$). O...

This is a really interesting FHE paper in which BGV is used to build an ALU to do arithmetic as well as logical operations on messages in Z_2^n (e.g. 64 bit machine words).

Homomorphically Encrypting CRDTs | jakelazaroff.com Homomorphic encryption allows a computer to run programs on encrypted data. Learn how homomorphic encryption works through interactive examples, build a homomorphically encrypted CRDT and see whether ...

📝 new blog post! i spent a while looking into homomorphically encrypted CRDTs. spoiler alert: they don’t work super well!

(but you should still check it out — i break down what homomorphic encryption is and how it works, and there are lots of explorable explanations along the way!)

Video of my talk in zksummit about Ligerito has been published!

It’s about the work by Andrija and @lmao.bsky.social introducing a small and concretely fast polynomial commitment scheme

Since then, a fun thing has happened —

As a reminder: this is a proposed law that would mandate the inclusion of scanning technology into all encrypted private messages. It would fundamentally alter the privacy guarantees of encrypted messengers.

There is this feeling, about spending days and nights reading papers and doing code, while listening to music and chatting with friends.
Going to sleep late hoping to wake up soon to continue working on a problem.

In some years I will call this nostalgia.

Link to the HyperNova paper: eprint.iacr.org/2023/573.pdf
the previous images unfold the section 5 for μ>1, ν>1.

similar applies to steps 4, 5, 7 and 8 of the multifolding.
In this image is shown the step 5 for 2 LCCCS & 2 CCCS, and then the generic equation for μ, ν.

If you're curious on how the HyperNova multifolding looks like for μ>1, ν>1 (more than 1 LCCCS&CCCS), in this screenshot I've tried to unfold it following the indications that Srinath gave in the PSE-HyperNova talk (https://www.youtube.com/watch?v=pDFmANwwIoY&t=724s
