https://ocean.xyz/docs/tides explains why (or at least how) the sats earning appear to be low on Ocean.

It spreads the earnings over the next 8 blocks found by Ocean. One could debate if this is blurring the 'custodial' issue, but in my case (just heating my house by mining) the wait for minimum payout is so long that it does not matter much having to wait for another 8 blocks.

Turns out that I was wrong about that! Good. Look at this page for the explanation how 'Tides' works on Ocean pool: https://ocean.xyz/docs/tides

In a nutshell, it's spreading your earnings over he next 8 blocks (ie blocks found by a miner minion on Ocean) or so, to even out the daily earnings somewhat.

Hi, I have started to mine on Ocean but it looks like my bitcoin rewards are massively reduced compared to mining with my previous pool. Can someone convince me, please, that this is a temporary thing? I really like the idea of mining on Ocean, but I am mining to earn some sats and I will not tolerate a 80% reduction to the sats earned longer term. How many blocks would Ocean find per day with the current hashrate if luck was 100%?

Never mind my math.....

I used the time (while Ocean found no blocks) to add Ocean to the top of the miner list on all the SD cards that I use to adjust the heater power for my house.

And then continued to mine on my previous pool, already above minimum payout threshold, until Ocean found a block and then switched to ocean about an hour later.

Result: The 'Estimated Earnings next Block' are still low compared to the 'Estimated Earnings/Day'.

So my theory appear to be busted or maybe only half of the truth.

How about this: Maybe Ocean should be finding 4 blocks per day (at average luck) and that's why the next block will only pay me half of what my 'Estimated Earning/Day' are supposed to be?

But this also means that it's a bad idea, economically speaking, to start pointing hashrate to Ocean when they have had bad luck for a while. I could continue to earn a fairly predictable amount of sats every day on my previous pool, while I am guaranteed to share in the bad luck already dished out on Ocean in the last couple of days.

The rational thing to do is to switch to Ocean immediately after they found a block, and hash elsewhere until then.

I hope I'm wrong about that, somehow......

That is a good question!

I have another good question: How do you post a question on Nostr so that it gets seen by the right people?

I searched for #bitcoin #mining #ocean because I wanted to ask the same question about the 'Estimated Earnings Next Block' being so low. That's after continuous mining for more than 24hrs, so I would have thought the number should be larger than the expected Estimated earnings/day.

But guess what, I figured it out right now! 🤣

Funny how that works, brain engages differently when someone else has the question.....or it's just because now I know it's worth thinking about it.

It is because of recent bad luck! Let me explain:

All those miners who have contributed hashes (since the last block was found by Ocean) get paid their share according to how much they have contributed. They got nothing since the last block was found, bad luck. If any newcomers would get paid their average daily expected number of sats, then they would get paid WAY more per hash than those who have continued to mine on Ocean despite of the recent bad luck.

I'm looking into it, bit short of time at the moment. Will get back to you when I can.

I have been entertaining the idea of building some Signets for myself, but so far I failed to find the required hardware information.

How many attempts do you get in total?

You seem to be the kind of guy who might know the #gpg #fingerprint for the #qubes master signing key #QMSK.

Just trying to find 'independent' verification for it.

The one I have downloaded has the signature #DDFA1A3E36879494

Do you re-use petri-dishes? I hate the idea of buying sterilised plastic dishes and using them just once. I want to fill (and ideally re-fill) the dishes and then sterilise them. I found PP5 sauce containers (about 50ml zsize) useful for that. I think the higher wall to bottom surface ratio (taller shape factor) allow for some bubbling while it's in the pressure cooker, while standard petri-dishes probably boil over, stick together, and end up with continuous agar-bridges to the outside for contamination to get in.

The images look good. What are the black dots in your agar?

What's your opinion about the smallest UTXO size that will remain viable long term?

The screenshot of OpenScad model ended up at the end of the code. Here it is again:

4 small cable ties can be used to secure the adapter to the fan grill on the Apollo. But it can also just sit on top loosely.

The Noctua 200mm fan comes with a splitter cable that can be used to power the Noctua at it's full 800rpm while the 90mm fan is running with pwm variable speed.

Lets see how Nostr copes with a bit of code

Paste the following into OpenSCAD to make a 3D printable Apollo to 200mm Noctua fan adapter:

You get good results with a 200mm Noctua fan on top of the Apollo, and a fan with less than 2000rpm minimum speed in place of the original fan. Quiet enough to gently heat a bedroom, but only with a silent power supply. The stock power supply is much much louder than an Apollo modified as above. I use San Ace 92 9GA0912P4J031

How hard is it to get started with Qubes? And does it run well on gaming laptops? I mean, can you run a gaming OS somewhere inside Qubes and it will take advantage of a high powered graphics card?
