Weren't you going to move your c-lightning node and keep it running?
Yes I was going to keep both running a lnd based node in a box and a c-lightning regular build, both VMs. The machine I put them I thought had 16GB of ram so I could run 2 VMs and still have plenty to spare. But it only had 8 so I was running both with just 3GB of RAM. So I was just going to shut it down, pull out the 2 4GB sticks and put in 2 16GB sticks. Also add a 2nd 2 TB so I could mirror the drive. Had issues and going back to tired / hungry instead of going though stuff slowly I decided to just to a bunch of things at once. (Flash BIOS / different ram / pull 2nd drive) Things went downhill from there. Nothing of which should have caused the issues, but both VMs became unstable. And the last backup I had done was last week when I moved them to the new box. So no help there. Will wipe everything and start again. -Dave |

So we all know this, but let me say it because I just did it.
Do not work on your Lightning Node OR ANY CRYPTO THINGS THAT INVOLVE REAL MONEY when you are distracted / busy / tired.
I have had several things I wanted to do including getting my c-lightning node back up and updating a few other things.
It was a busy couple of weeks and finally, today I figured it's the 4th of July, the office is closed, I can go in and take care of Dave's stuff.
Yeah, well. I was up late last night, got up early today and really should have just stayed around the house and relaxed.
But, I took care of a bunch of stuff around the house, did a bunch of "beginning of the month paperwork and bills" and then went to the office, skipped lunch and began moving hardware before I did the software updates. Which I screwed up...big time...because I was tired and hungry.
I managed to get the node back up and broadcast the close channels.
And, no I did not do a backup because why bother for some minor hardware work, I'll do it before I do the software upgrade.
Stupid....stupid....stupid.
I know better. Never touch hardware without doing a complete backup. But I was hungry and tired and wanted to get it done and get home and watch the fireworks.

1) it's not the Koch brothers it's Fortress Investment Group which includes their own money and the Canada Pension Plan and Koch Real Estate Investments.
2) There was another takeover bid from someone else last month. So it's not like this was unexpected.
3) Morrisons owns it's own supply chain and that makes it a prime target for investors because it's easier to squeeze every penny out of it when you control more.
At a guess, since Brexit is killing a lot of businesses across GB they figure it's going to simple to squeeze out some profit and sell off what is left.
As of now NONE of the businesses we do IT for have anything left in GB / England due to Brexit but they have found a lot of willing buyers to take over and price gouge the people who need what they were selling. Sadly we didn't get to get any of that profit. But I can easily see this being the same thing

I wonder if the new countries will allow them to stay.
A lot would probably depend on the amount of spare power they have. That is the issue in a lot of places. You can get a lot of clean renewable energy BUT it's in remote areas that are never going to be "built up" AND it's not always simple or even remotely cost effective to build power lines to where it's needed. So you have a lot of power and nothing to do with it. Mining solves that as it needs a lot of power but not a lot of space or infrastructure beyond that. -Dave |

10 years ago 1TB SSD were insanely expensive. Today they are under $100 USD
Bandwidth price is falling in most places. 5G is allowing very high speeds for downloads even when you do not have the ability to connect to a local provider.
RAM & CPU pricing is falling too.
So there it's no big deal.
If you want to run a node on the PC that you just pulled out of the trash that is one thing, but if you are going to spend some money then it will be fine.
Same as now, you can run a node on a slow internet connection on a RPi3 with a slow drive attached to it.
Or you can get a 4th gen core i5 with 16gb ram and a 512GB SSD for under $250 and not worry about it.
You can probably save $40 going for a similar generation AMD based PC.
10 or 20 years from now the systems will be different but theory will be the samw.

Well the answer was a drop of 27.94%.
So the next question is that going to be stable for any period of time?
I don't think it will be. I feel there will be a lot more spikes up and down.
No scientific or logical reason, just a gut feeling that big mining farms are going to be a lot more aggressive in where they mine.
They moved once, they can do it again. As opposed to the "we built it here, so we will stay here" theory.
Just my thoughts.

As BitMaxz there are some firmwares that will allow you to run without fans.
However, the way the boards are designed you do have to get a large amount of air moving over the heatsinks.
You need a bit of positive air pressure moving through them.

Obviously we'll see it play out in court, but I doubt these crimes will be baseless because let's be honest, every one of these wall st exec have their hands dirty. Still though, innocent until proven guilty, always. It'll probably be a case of "barely legal."
Say there are two traffic cameras exactly one mile apart in an area in which the speed limit is 30 MPH. The DA could review the footage, see that a Trump associate took 116 seconds to travel the ctemtsdistance between the two lights, and charges him with speeding. The Trump associate was breaking the law -- he was going 1 mile over the speed limit, which is illegal, but this does not mean that the law is applied to everyone else, or that the DA was not looking specifically to charge this particular person with a crime. If the Trump org was audited in the timeframe of the alleged crimes, this would probably be a pretty strong defense, especially if the audit was done by the NY IRS, and even more so, if the audit resulted in additional taxes being paid not involving the fringe benefits. The amount of tax revenue that NY state lost out on is very small, and is probably less than the cost of the investigation, somewhere in the range of $8000 or so per year over 15 years. This is also not to say that the Trump org didn't offset some of this with higher corporate taxes on their end. [/quote] Bad analogy here in NY traffic cameras show your speed as you were going past them. Usually with both radar and another method. I have a collection of some really nice shots of my motorcycle from them if you want. It's an instant image at an actual moment in time of how fast you were going. As for the taxes: Remember you pay part of your income tax and the company pays the other part. If what was released was true they, were paying for other things (some of which were over $100k) for him and others and not recording it as income. So your $8k number is WAYYYYYY low. And yes they were audited during the time, but the audit was paused during the time DT was president. And on top of all of that, so far they have just charged them for 1 person many more are coming. -Dave |

More or less what Phil said. The reasoning behind it is: As a rule a PDU is designed to be running 24/7/365 at full power in data centers / equipment racks. But they do not smooth out the power. The cords you are showing will work but they are more for temporary use and not for 100% power all the time.
With that being said, they will work. But with the amount of power you will be putting through them do you really want to risk damage to your equipment or an electrical fire to save a few dollars?

Did you look at bitmedia.io ?
I have been using them on a couple of sites I have. No idea if they support faucets or not.
Ad revenue is tough and has been getting tougher. I actually don't even expect to get any money in anymore, it's just a "bonus" when it happens.

I'm not in a hot place like Mikeywith is, but still, 90F/32C (?) sounds like something usual for the start of the summer, the temperature in both Vienna and Prague have already hit that mark, and it's not July yet. I just look at the average temperatures for Seattle and from what I see there have been quite a lot of times when it went past that so if you're building your farm with that little tolerance....
https://www.npr.org/2021/06/29/1011269025/photos-the-pacific-northwest-heatwave-is-melting-power-cables-and-buckling-roadsIt's far above normal, but it not just that. There is a difference between hitting 95F for an hour or two in the highest point of the day and then dropping down or like it is now with it just sitting at that temperature for hours and hours. The gear cooling might be badass but I think your own body cooling is far more intriguing, I can easily deal with -25C, but when it goes above 35-57C I turn into a useless mass of precooked jelly.
I'm the opposite. I can take the heat, but the cold just makes me ache. I hate putting on layers and layers of clothing just to go outside for 10 minutes. Here in NY, it's not been terrible. It's just fact that it's the end of June, and this is the middle of August kind of heat. Why would they even bother to convert ltc and some other coins to BTC? They can sit on it. They should have more then enough BTC to keep paying out what they have to.
It's going to be interesting to see what happens over the next few months. Will the big farms that are not part of the miner manufacturers come back online or will they start selling off their gear in with the plan to have money available for when the new more efficient gear comes online. -Dave |

Read through this thread: https://bitcointalk.org/index.php?topic=5162419.0Short version: Sumcoin is a scam. And there is no way to sell them. The developer has blocked everyone who asks questions. There is github for the wallet so you can't compile your own. There is no trade volume anyway. Sorry but it's a scam. -Dave |

...though it doesn't take 6 months to get transformers...
Yes it does, small units yes are days or at most a couple of weeks. Larger units, can easily take months and months. Unless you have a large amount of money to throw around. This is not even a friend of a friend thing. *I* know 2 places, both customers of the company I work for that had to have a 20MWA transformers replaced. Both took 120+ days between PSEG telling them they had to buy new ones and the delivery. And they were ordered within hours of the go-ahead since the issue was known. Could have had a pair of 10s in within a month or less. But the larger ones, nope. *Yes you can get used ones, or non "name brand" ones, or imported ones for less. Good luck getting insured or an electrical inspector to sign off on it if you put those in. And that is what causes people to think you can get them sooner. There are a lot of used / refurbished ones out there that are 100% fine. Ford can put them in their factories since Ford is responsible to Ford and a Ford electrician signs off on it and they are insured by some company they can boss around. Dave's customer in a small industrial building whos unit was failing when hitting 80% got no choice. They had to get new. But, back to the hashrate drop. Due to the heat hitting the US Pacific NW I know there are some places that cannot keep up with cooling so they are shutting off miners during the day. If you based your cooling on 90F as max sustained outside temperature, with 95F as a limited daytime hours temperature and it's been hitting 100+ every day for hours and hours, yes you might be shutting some things off before your cooling system tells you it's going on vacation.  So there is some loss from there too. -Dave |

WTF?
I noticed that their absolute fee are all too " exact", suggests that they've set the total fee when creating the txns, not the fee rate. Sender(s) may be unaware that the prioritization is based from the fee rate or doesn't care about the extra fee and most likely using a client that can input/edit absolute fee other than the fee rate. For example, those first three with 2,291sat/vB (x2) and 822.0sat/vB have a 0.005BTC fee, and some of the rest with extremely high fee looks the same but lower ( 0.002BTC absolute fee). Did not think of that for some reason. It's been a while since I did any real trading on exchanges and while I do remember some of them charging high fees I also remember a lot of them not actually paying them. It was just another profit center... You would think that they would stiff be charging .005 and paying .000005 and pocketing the difference. That's just good business. As someone mentioned above, when you're transacting millions, nickel and diming on fees isn't really a concern. What's $150-200 when you're shifting $5mil worth of coins?  These are exchanges that are most likely processing withdrawal transactions. This is not the exchange's actual money that is being moved, it is money they are hold for and on behalf of their customers, and will have to make up for high transaction fees in the form of trading fees (or other fees) paid by their customers. If they are paying $200 when they could have paid $2 10,000 times, all of a sudden, they have paid almost $2 million extra worth of transaction fees. And if you have outside investors that is when bad things happen at times to management.... Yeah, it looks like some preconfigured system that is setup using absolute fees as opposed to calculating fee rates. Not sure why you would do that, but there you go...
Aside from poor preconfigured system, it's also possible it's set up by intern or worker who're underpaid. Or they were undertrained. Or overworked. Well thanks everyone I guess that answerers what I asked. -Dave |

I have been seeing more and more very large fees paid for transactions at times well over 20x what is needed to get into the next block. Is this just badly broken software doing fee estimation or something else? Looking at: https://btc.com/000000000000000000076e53c720e850cc46fcbc42a65f7aa0917755daec3c22We have 2 transactions at over 2k sat/vbyte 1 at 800+ 1 at 500+ and dozens at 200 to 300+ You could have gotten into the block @ 30 sat If you wanted to be SURE, then do 60 sat. WTF? This seems to be happening a lot lately, either I am just paying more attention to it and it has always been happening or??? -Dave |

PPLNS in general is not a 'risk' as you claim.
PPLNS has higher variance than PPS because the PPS pool pays the variance
These two statements contradict each other because variance is a risk unless it's measured against infinity, your theory is only valid if I could mine to infinity, at which, even solo mining would yield the same results, but we know that: 1- The mining gear will die 2- The mining pool might close 3- The profitability drops and miners are forced to shut down. And probably a few more hundreds of things that could wrong. IF (that's a big IF) a pool has enough hashrate which in theory is capable of reducing the variance close to zero, then ya, other than that, it still is a risk, the risk with smaller pools is even greater, the mining gear might die before earning a single sat, whereby mining to a small PPS pool with no variance you are guaranteed to make a profit unless that pool is broke due to lack of funds, but then you only lose 24 hours (or whatever the payout threshold is) of mining, whereby in PPLNS pools you can lose anything from 1 day to 11 months and your gear might very well break before the pool hit a block, if that does not qualify as "risk" to you then I can't convince you otherwise. You are not guaranteed to make a profit mining with PPS, you are guaranteed to earn some BTC. A small but important distinction. :-) Also, the other thing with PPS is there is no penalty to leave. You stop mining BTC to go mine some alt because it's having a run up in price you don't have to worry about ramp up or ramp down time. Of is the PPLNS pool is shrinking and hitting blocks, or any other reason. You stop mining at one pool you just stop earning at that point and go somewhere else. And as I said before, every persons situation is different, what works for you and me may or may not work for someone else.
Side note: you should never be mining at a small PPLNS pool around having time. In a few years going from a percentage BTC6.25 reward to a percentage of BTC3.125 because the pool did not hit a block will not be fun. -Dave |
