A friend sent me, sharing with y'all
Happy 45²
2025 = 45² is a "perfect-square year."
It is represented by the square of the sum of all digits in the decimal number system.
(0 + 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)² = 2025.
It also represents the sum of the cubes of all digits in the decimal number system.
(0³ + 1³ + 2³ + 3³ + 4³ + 5³ + 6³ + 7³ + 8³ + 9³) = 2025.
The last "perfect-square year" occurred in 1936, and after 2025, it will only happen again in 2116.
Happy 45² to all of us!!!
An excellent 2025 to you!!!

They can't, because they assume that nonces are:
- The very last thing in a 80 bytes digesg
- Binary (nostr uses strings)
Even if you make the nonce come at fhe end, and precompute the midstate for the first block. You still need to have a closing "] to make the json valid. While you could do accieve the latter by fixing the nonce range to keep the last bits fixed, you lose a lot of nonce space.
And again, your serialized note should be exactly 80 bytes

Context: Tor Project's executive director (a Brazilian, apparently) published the following article, endorsed by the Tor project itself.
https://www.intercept.com.br/2024/09/03/vpns-protegem-a-sua-privacidade/
The decision by the supreme court has two parts:
Banning X.
Fining everyone that uses vpn to curcunvent the decision.
Even the state sponsored media was against the latter, citing that people use VPN for other reasons.
She followed exactly that narrative, saying that the former is ok, and that "Elon is not above the law" (even though he's the only following Brazilian law).
As someone living in this mess and exposing myself the risk of being jailed for running tor-related things in a dictatorship, I thought the Tor Project would stand against the abuse of authority and complete erosion of free speech here. The fact that they think it's ok, makes me not wanting taking this risk anymore.
I still run some publicly reachable Bitcoin node unde my personal IP, bacause I believe in Bitcoin and I want the network to succeed. I have an average of 300 simultaneous connections and upload an average of 2TB/month, helping others to connect with the network and download stuff.
I used to do that for Tor too, but I won't do that anymore. I don't care what other do or think, I'm just not taking this risk anymore.

I don't care what other do, but the exec director posted an article that stars by licking Alexander's boots and regurgitating the regime's propaganda.

Someone just posted on the ML
```
I'd like to propose an idea of a simple logarithmic-size ring signature scheme
which can be used in the blockchain and related applications. The signature is
called LS-LSAG, a draft of it is available at https://eprint.iacr.org/2024/921
In making this announcement I'd like to ask the community to comment on
the idea if anyone is interested.
LS-LSAG has such a design so that it can drop-in replace the well-known linear-size
LSAG/CLSAG signature. Also, it looks compatible with the full-chain Curve Trees,
which in turn can drop-in replace both LS-LSAG and LSAG/CLSAG at the price of
using one more curve with specific properties.
In more detail, LS-LSAG is built up of almost the same systems of equations as
LSAG/CLSAG. However, it makes a call to the inner-product argument instead of
doing the sequential challenges. This results in the size reduction from linear to logarithmic and in the compatibility with LSAG/CLSAG. Particularly, LS-LSAG and
LSAG has the same key image.
Formally, LS-LSAG is a log-size linkable ring signature without trusted setup in a
pairings-free prime-order group of EC points under the DL assumption.
Unforgeability of LS-LSAG follows from the DL and collision-resistance of the
standard hash-to-curve function, the draft contains a detailed proof sketch of this.
```
