Concept is great. Practical feedback: I'm having a hard time figuring the system out, not sure if this is because I'm on Firefox, UI/UX issue, network latency, or I'm just dense (likely). For example, It shows in the R side bar "10 players" but I am not listed among them? Additionally, I can not see who has what territory. https://blossom.primal.net/7d46755e28bdfb732f5aa8084996c9ab3b3a38b3363ec5a011c920ac68ce252c.png

Briefly; Eufy has had a lot of problems including "encrypted" streams not really being encrypted (https://www.channelnews.com.au/eufys-chinese-owners-finally-admit-their-security-cameras-were-a-security-risk/) as well as that they are Chinese owned and manufactured.
Ubiquiti is US owned and Taiwanese manufactured; and further I use a complete Ubiquiti networking stack (gateway, switching, wifi) so it was a great fit.

Bitcoin has existed for >5 times as long (17 years) than tulip mania (3 years, 1634-1637). Considering that information travels, and the world changes, much faster now than in 1637, this is like 100x the lifespan. Altogether this suggests that Bitcoin is nothing like the Tulip Mania fad of the 17th c. The end.

Thanks for helping reveal unspoken predicates and assumptions on my part. To be clear, I already had a self-custody lightning node and have for many years. This can be hosted at home and exposed on clearnet, run on Tor, protected by VPN, Cloudflare tunnel, or other means. LND is easier to find compatible LNURL-pay software. Liquidity costs (for inbound channel) can be pretty low. Alternatively, you can open outbound only (free), spend sats as you would normally, and anything you spend becomes inbound liquidity to your node.
If you can run LND or Core Lightning, you can surely also run the LNURL-pay software, so no extra costs or overhead there.
You will need a domain which runs you $10-$50 / year. I use porkbun.com

2025-10-20 12:38:42 UTC

Being on nostr since 2022 I just sort of set up my lightning address with a Wallet of Satoshi address and forgot about it (to say nothing of my mercurial use of nostr).
So many zaps over the years ... like tears in rain (Bladerunner.jpg).
Anyway I finally got around to self-hosted LNURL pay/Lightning Address/Zap infrastructure and now I need to come up with some banger notes to make up for lost time and lost sats.
AMA about self-hosting a LNURL-pay server + Lightning Address I guess

Interesting stats. I notice that there are some merit badges that are super anachronistic. Others seem so vague as to be useless ("inventing"?). I believe there should be a foreign language merit badge, although the amount of work that implies could be disproportionate to others.

Imagine a chain tip that looks like (A, B, C) where C represents the most recent block, and the one in which your transaction was included. Suppose next that a miner who had been working with (A, B) looking for C shortly after finds a different block, C‘. Should/could/will the next miner to find a block D build on C or C prime? If they build on C‘, your tx is no longer included in the longest chain. c, containing your block is an "orphan block". This is a simple version of a "chain reorganization". The 6 block rule of thumb seeks to minimize this probability (that your tx is reorged away)

BUT! as I've posted elsewhere, I recently returned from a 9-10 month break from nostr and have some first-hand perspective. Overall while the experience _looks_ nicer, it's certainly not _easier_.
Until my grandmother can join and participate fully (incl zapping), it's a plaything for technically-inclined Bitcoiners and if we're lucky, other freedomtech-oriented subcultures.

AHA. It's a Primal-Alby interaction problem. Alby error (see below) crashes primal. If I enable Alby to run in FF Private mode, Primal no longer loads. Removing it again restores ability to load Primal.
Alby shows the error "Error: e.payment_hash is undefined" when browser URL is `primal.net`. Evidently Primal fails to parse (and then just fails) some WebLN API response?

Thanks for that. I've probably been thinking about this wrongly. In a hyper inflationary env I guess the central bank has competing priorities: high rates need to bring inflation under control, but low rates preferred to allow government to still service its debt. I'm still curious which would prevail in a debt spiral.

2024-01-26 15:30:40 UTC

Does anyone have historical data on what happens to interest rates in hyper inflationary and/or debt spiral scenarios? I assume they are zero to negative? There may be little to no data as to when that happens with a world reserve currency. @npub1a2c…w83a

Yes, and dozens of other similar tiered plans. The issue is that my low tier plan is really B2C (although the consumer would use it in their professional capacity), while the high tier plan is B2B. Anchoring and relative positioning advice for getting consumer hooked enough to push the business to get enterprise plan is what I'm looking for. I'm very much opposed to a free plan at the low end based on well researched data on conversion rates (~ 3%). Anyway if anyone does this for a living I'd pay for consultation.

Niche product for managing industry-specific documents that lies between "nice-to-have" and "can't believe how I lived without it". No competitors in the space. Value to customer is time saved and improvement in apparent competence by enhancing professionalism of their external-facing documents. Big difficulty I have is pricing the individual plan (hook them) vs. enterprise group plan (without a sales team, I'd rely on satisfied individual users to kick up to management).
