"Spain has arrested one of its top police officers after €20m (£17m) was found hidden in the walls of his house, as part of an investigation into the country’s largest-ever cocaine bust.
Óscar Sánchez Gil was until recently the head of the fraud and anti-money laundering division of Spain’s national police force in Madrid."

We ran both lightningd and lnd in the beginning. But when we had to move to new hardware after a couple of years, there was a weird edge case bug with c-lightning that prevented us from moving its database to a new box, so now we're left with just the lnd. ¯\_(ツ)_/¯

My old ThinkPad has been running pretty well as a full node with Electrum server etc. since I set it up. The only thing I haven't gotten to work yet is automatic boot unlocking with Tang and Clevis (which works fine with our rack servers in a private location). It's one of those things that are so tedious to debug and fix, that I hardly ever find the motivation for it.
We do have extended power cuts on this island at least once or twice a year, and sometimes they're too long for the UPS to keep everything running. But it's also nice to be able to reboot remotely for kernel upgrades and whatnot.

Sorry, I see what you mean now. The relay would have to reject edit messages that are too late, because the client could be offline and doesn't get a timestamp from the relay, only from the sender. But people don't want smarter relays, so that's out of the question I guess.
Delayed sending on client-side is definitely better than not trying to solve it at all!

2024-11-07 19:56:28

- reply

It just means that the mentioned scam is not a good argument, since this is not happening on other protocols that support edits currently.

2024-11-07 19:54:52

- reply

The edit window is always just a thing that clients do, see e.g. https://xmpp.org/extensions/xep-0308.html
The whole point is that it's not guaranteed to show the edit everywhere, and that clients can choose what they think is the most reasonable course of action.

2024-11-07 19:06:48

That scam wouldn't work with a short edit window, which is exactly what all decentralized protocols with editing are doing.

For Lightning, that would be both liquidity and security (e.g. the election bet on Poly was the size of 9+ entire Lightning Networks).
For on-chain, the problem is how to handle the actual contracts and uncheatable/uncensorable payouts to thousands of addresses. For that to be decentralized you need more contract logic than bitcoin script provides. Likely a good idea to wait for a production-ready off-chain smart contract platform (based on whatever ZK proofs/rollups/etc.) to arrive. Or bite the lemon and deploy Poly contracts to RSK. 😅

Aside from whatever opinion you have on political parties or politicians, here's a neutral fact to consider:
The NY Times just called the result, and at currently 224 vs 277 votes, these numbers almost exactly mirror the Polymarket odds from directly before the election.
All legacy media were wrong about how close of a race it was, while markets (including normal bookies) predicted the result with almost perfect accuracy.

I think the #indieweb concept of POSSE (Post to Own Site and Sync Elsewhere) should become PORSE.
Doesn't sound as cool, but since your own site is also dependent on DNS, it's the ultimate post-to-own-anything. It wouldn't even have to be a relay, we could also call it PODSE, i.e. post to own drive/disk/device, then sync elsewhere.

If Yubico adds native support for nostr key import and signing, then that would work. Otherwise, you'd have to store an encrypted nsec, which doesn't bring any benefit over storing it on your computer directly.

The problem with a network this small is that, to a certain degree, the network is close to being just one large community, instead of many overlapping smaller communities. With federated systems it's more obvious that the people you might strongly disagree with come from different domains, which just also happen to be able to communicate with yours. But I think a network without this required affiliation needs a certain minimum size to become home to a truly diverse set of people.
I think both community-focused software as well as non-social-media use cases are the solutions in the end. If Will can't post stuff like that without it affecting new users, then the entire protocol is DOA, isn't it?

It's beyond me why Zcash is not regarded as a complete shitcoin. Here's the first reason Zooko states for why Zcash will switch to Hybrid Proof-of-Stake:
"It reduces supply of ZEC by locking up staked ZEC and increases demand for ZEC by giving people something else to do with it."
Not enough demand for "money"? People have no idea what to do with their "money"? Let's lock it up and reward investors with dividends!
Now imagine someone looking at this chart, even adding it to their own blog post, and then linking said post with the comment "Zcash is winning":

Tether already looks a lot like a semi-private U.S. CBDC. And it makes sense, since the Federal Reserve banks are privately owned, too. May as well extend the current collaborations with some kind of permanent oversight board, stacked with more government bureaucrats.

Both adding Nostr support to a feed reader, as well as adding RSS/Atom support to a Nostr reader (that is optimized for long-form content) would be nice to have. It's basically the same app and the protocol shouldn't even matter much to a user. Ideally the experience is exactly the same when you paste a Nostr URI as when you paste a RSS or Atom URL.
I rely heavily on Feedbin for most of my news and long-form content, so for now I'll just subscribe to Nostr feeds using my own Nostr feed generator. There's hardly any long-form content on Nostr as of now, so opening e.g. Habla a few times a day, with zero updates for most of the week, was too frustrating of an experience.

I think that just means you haven't looked into the topic enough yet. I'm INTP and my partner is INTJ, and these two types are quite different in some ways.

The next step is to create human-readable URLs, i.e. `/@username/article-id`. But my favorite feature will be `/@username/articles.rss`, because if it doesn't have an RSS feed, it's not a blog.
