#[0] thanks for a nice presentation at nostrica! There was some discussion on having a nostr keys as sign-up in other services. I was impressed by how vida.page manages it. You can set up a profile there by using only the nostr profile, no e-mail/phone etc. required. They don't ask for nsec key in sign-up/sign-in but only npub and a relay. They then send a verification key as nostr private message. Kind of the same way an email sign-up works. Of course you still have to have a good nseckey handling when using the nostr client, but there is no need to trust the nsec-keys to any app/service that does not need it to sign stuff.

I just tried the new Bing GPT-4 based chatbot. It is so badly screwed up that it is hard to understand. I asked about US banks reserve requirements and it confidently answered: 10% or 3% if certain conditions apply. I pointed out the truth that the requirement was dropped to 0% at 2020 whem covid hit. Bing confirmed this, but did not want to aknowledge that it provided false info at first. Then I asked if the 0 reserve requirement made bank runs more feasible. It brought up SVB. This was how it explained the SVB default: (Note! Totally flase info here.) Also, the "references" 1) cnbc, 2) latimes 3)washington post, did not contain anything that actually backed this story. Delibrately misleading or just a really bad AI?

There is no cloud! There is either your computer or somebody elses computer. Google reminded me that I am having a backup of my pictures at Their computer. Translation: "Backup space is almost full (83% used) Soon new pictures cannot be backed up and will not be visible in memories or search results Not now / Start 100 Gt trial" Related to this, what is the best method to start your own home media server? Small amount of technical difficulty can be accepted.

Bing search coded this for me. I was looking for a way to easily generate a wallet and the 12 words and a mnemonic on a offline computer with a way that I could easily verify: python code. What are the key errors with errors? Here is a possible Python script that will generate a bitcoin private key and a corresponding bip39 mnemonic, based on some web sources123. Please note that I cannot guarantee its correctness or functionality, and you should use it at your own risk. # Importing libraries import os import binascii import hashlib import hmac from ecdsa import SigningKey, SECP256k1 # Generating a random 32-byte private key private_key = os.urandom(32) print("Private key (hex):", binascii.hexlify(private_key)) # Converting private key to WIF format extended_key = b"\x80" + private_key checksum = hashlib.sha256(hashlib.sha256(extended_key).digest()).digest()[:4] wif = binascii.hexlify(extended_key + checksum) print("Private key (WIF):", wif) # Getting public key from private key using elliptic curve cryptography sk = SigningKey.from_string(private_key, curve=SECP256k1) vk = sk.get_verifying_key() public_key = b"\x04" + vk.to_string() print("Public key (hex):", binascii.hexlify(public_key)) # Hashing public key with SHA256 and RIPEMD160 to get address sha256 = hashlib.sha256(public_key).digest() ripemd160 = hashlib.new("ripemd160") ripemd160.update(sha256) hashed_public_key = ripemd160.digest() print("Hashed public key:", binascii.hexlify(hashed_public_key)) # Adding network byte and checksum to get address in binary format network_byte = b"\x00" bin_addr = network_byte + hashed_public_key checksum = hashlib.sha256(hashlib.sha256(bin_addr).digest()).digest()[:4] bin_addr += checksum # Encoding address in base58 to get final address alphabet = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz" base58_addr = "" value = int.from_bytes(bin_addr, "big") while value > 0: value, mod = divmod(value, 58) base58_addr += alphabet[mod] base58_addr += alphabet[0] * (len(bin_addr) - len(bin_addr.lstrip(b"\x00"))) base58_addr = base58_addr[::-1] print("Address:", base58_addr) # Generating bip39 mnemonic from private key using PBKDF2 algorithm wordlist_file_path="english.txt" # Change this according to your wordlist file path wordlist=[] with open(wordlist_file_path,'r') as f: wordlist=f.read().split('\n') mnemonic_length=12 # Change this according to your desired mnemonic length (12/15/18/21/24) salt="mnemonic" # Change this according to your desired salt iterations=2048 # Change this according to your desired number of iterations dklen=mnemonic_length*11//8 # Derivation key length in bytes hmac_hash=hmac.new(private_key,salt.encode(),hashlib.sha512).digest() # HMAC-SHA512 hash of the private key and salt dk=hashlib.pbkdf2_hmac('sha512',hmac_hash,salt.encode(),iterations,dklen) # PBKDF2 derivation of the hash using SHA512 and salt bits=bin(int(binascii.hexlify(dk),16))[2:].zfill(dklen*8) # Binary representation of the derived data words=[] for i in range(mnemonic_length): word_index=int(bits[i*11:(i+1)*11],2) # Index of each word is 11 bits long words.append(wordlist[word_index]) # Getting words from wordlist based on indices mnemonic=" ".join(words) # Joining words with spaces to get mnemonic phrase print("Mnemonic:",mnemonic)

Question I have started to feel like the sats have a different valuation in nostr than what the official market price suggests. I mean that 1000sats does not feel like 20$cents but in valuation closer to a dollar. Has anyone else noticed this? Is it just the anticipation of future possibilities that I am counting in? Anyway, nostr zaps have made it intuitive to think value in satoshis - independent of "currency conversion" rate. This is a great leap towards wider usage.
