haha! not much grafana/prometheus content out there yet for BitAxe yet I suppose. The dashboard I showed here is in my PR in that repo.

Make sure to follow the instructions, as you have to SSH into StartOS to forward the stratum port. (Hopefully not needed anymore when StartOS 0.3.6 or 0.4.0 comes out).

It already works! I wrapped public-pool for StartOS here: https://github.com/remcoros/public-pool-startos/
When StartOS 0.3.6 is released with more options for port-forwarding, I will submit it to the Start9 marketplace.

Actually, there is more CPU mining then asics on testnet4, they just fake the block time to get the lowest difficulty. Look at this (mostly difficulty 1 blocks):

How do you calculate the hashrate of testnet4? Because what is shown on pools (like testnet.vkbit) and 'getmininginfo' RPC is completely wrong. This is because people mine future blocks with their CPU, so there is a lot of "difficulty 1" blocks, which completely messes up the hashrate calculation.
If you want to calculate the chance of hitting high enough difficulty requirement, you should only use that. e.g. P (probabilty) = 1 / (difficulty * 2^32).
You can get the difficulty from a block that has difficulty > 1 (most blocks on testnet have difficulty "1" because they set the time of the block (nTime) to 'last block + 20 minutes', and then use CPU (or bitaxe or whatever) to immediatly hash that block.

Hi Ben, awesome video as always. I have to note though, the part about connecting to StartOS is not correct. Wasabi does not use electrum (electrs) nor the Bitcoin Core RPC API (port 8332). You can connect to a Bitcoin Core P2P port (8333) to speed up filter downloads. (which is not supported yet on StartOS 0.3.5).
The architecture of Wasabi is quiet different than for example Sparrow. Read more here: https://docs.wasabiwallet.io/using-wasabi/BitcoinFullNode.html

Supports mainnet and testnet4. A testnet4 bitcoin core node service for StartOS is here: https://github.com/remcoros/bitcoind-startos
Currently running a Bitaxe Supra on testnet4.
Note 1: StartOS cannot forward the stratum port yet, follow instructions from the StartOS UI (or Instructions.md on github).
Note 2: I haven't found a block yet and have not tested on regtest (yet).

It's a Pi4 with a custom case (can't remember which). It does run StartOS (for testing/development purposes). Production node with core/lnd and all is running on the NUC (as a proxmox VM).
Can't stress enough how stable and easy StartOS is. Even for me as an 'experienced' developer/sysadmin I prefer it over a bare OS like debian for day to day use.

Everything is done through the cloudflare dashboard (no ssh/terminal commands needed). Just install the service, fill in your token and manage everything from the CF Zero Trust dashboard. The only requirement is that you know your way around the Cloudflare dashboard. Which yea, maybe is a bit technical :)

I'm using StartOS with cloudflare zero trust tunnels. I can access all (http) services from a public domain, with SSL. Not exposing my home IP directly, and also avoid routing through TOR. Running BTCPayServer with Nostr plugin to receive zaps directly to my node. The free tiers of cloudflare also offer some basic ddos and bot protection. It has been working perfectly.

const clearly states intent, it's good for longevity of the code especially with multiple maintainers. Not sure about performance, I can imagine a runtime can make some assumptions for performance if it knows it's a const.

OAuth/OIDC flows are perfect for this, no need to reinvent the wheel and OIDC support in libraries/frameworks is pretty solid these days. Which makes integrating this in apps quiet easy I suppose if you can expose OIDC compliant "nsec bunker" endpoints.

Yea, @primal is broken I guess. this is what it shows for the note: https://image.nostr.build/6629b18187ea275f88a25472814c87e2dd737011891cc5e7093dc8ad2f198fd0.png
I checked pretty much everything, the lnurlp spec, nip57 spec, checked the sigs, checked the description hashes, compared 'working' zaps with non-working zaps. I don't see it... primal just doesn't render/show the incoming zaps.
Weird thing is. when I zap the other way around (from my account to test account). It works! Compared those 9734/9735 events with each other, I don't see a difference or why this wouldn't work...
Only primal though, nostrudel and amethyst work.
Time to switch for now I suppose.

2024-06-02 12:37:36

Hi @npub12vk…pugg any idea why incoming zaps on my profile and notes are not showing up in primal?
For example, this event id: b2ba049883e6d54fb934945732703ca0f475fe2784843ae1ffef9c2ab021a447
I can find the receipt event on relays, nostrudel shows them. But nothing in the primal (web)app.
I'm using BTCPayserver with Nostr plugin, setup seems correct.

There's more options coming in 036/040 for opening ports on your StartOS server, but that only helps if you want to expose it to your router, set up port forwards and directly expose your WAN IP address.
Using a tunnel (like cloudflared) hides your WAN IP. That is not something StartOS can provide (unless they are going to provide some cloud services for it, but I didn't hear anything about that yet).

Currently running a #Start9 #StartOS TOR only Bitcoin / Lightning / BTCPay server node including my own lighting address behind a clearnet domain+ssl. No VPS, no complex (and slow) TOR forwarding.
I'm using the free tiers of Cloudflare websites, ssl, dns and tunnels and the StartOS wrapper I made for the cloudflared tunnel client: https://github.com/remcoros/cloudflared-startos
Basic knowledge of how to setup a cloudflare domain, ssl and a tunnel is required but it's mainly clicking through the UIs.

Unfortunately not, this would require support from StartOS (at the linux kernel level), which is unlikely to happen. I tried to hack it on my own node, but couldn't get it working. Specter has a very different architecture in this regard, as it is a 'web application' and can use the browser API for that. KASM /webtop (which sparrow on startos is based on) can do this, but needs a virtual camera device on the actual OS (StartOS) and forwarded to the webtop container.
Someone asked something similar for USB device support, but that would require tighter integration from StartOS at the OS level and is confirmed not happening/planned by the devs.
