Anyone ever tempted to run a node off a solar panel? I assume a single board computer would likely be the most realistic way of going about it.
Not..... yet! I plan to get something relatively large but still single panel that would easily power a node even on cloudy days. The more ambitious part would be also developing a hashboard that is then dynamically powered on / off depending on sun availability. Mainly to show the counterintuitive concept of harvesting otherwise 'lost' energy (since the solar panel will produce much more than what a little pi needs on sunny days) and therefore run not only carbon-neutral, but you could argue carbon- negative mining.  I would disagree it's carbon-negative. You need to consider carbon footprint during production[1] and whether it's recyclable after the panel reached end of life/broken[2]. 1) It's not a 100% standard card and Dell has something custom either in the hardware or firmware that causes it to get funky under linux.
It's known problem that some WiFi and mobile broadband card doesn't work on linux. But what linux distro did you use? Have you tried install optional/closed-source driver (few distro require user to do it manually)?
[1] https://www.1energysystems.com/carbon-footprint-of-solar-panel-manufacturing/[2] https://www.nature.com/articles/s41560-020-0645-2.epdfI tried Debian and Ubuntu 1st figuring that when Debian did not work Ubuntu, although close to it may do something a bit differently. Then I switched to CentOS and still no go. Tried every driver I could find related to the card both open and closed. It's not even that smooth under Windows, after install you have to *power down* not just reboot. As for the solar panel side, since the nodes in a box use so little power you can probably get an older / damaged solar panel for free that will put out enough power to run the node and charge a few batts to keep it going when it's dark out. Depending on where you live. Here in the US it's going to be easier to do in say Las Vegas where you have a lot more sun then New York. https://bitcointalk.org/index.php?topic=5158920.msg58008085#msg58008085 -Dave |

Went with mynode in a VM for now because I could not get everything to work under linux and I wanted a lightning setup. No real reason, just wanted it.
What specifically didn't work in Linux, but works in the virtual machine? I could not get the 4G working under linux. It's a Gobi / Sierra Wireless / Qualcomm unit but no matter what I did it would not connect. Installed Win 10 and it works. VirtualBox sees it as a regular Wi-Fi card. I don't know if 1) It's not a 100% standard card and Dell has something custom either in the hardware or firmware that causes it to get funky under linux. Or 2) Since it's PD surplus if they did some tweaks to the firmware Or 3) AT&T is looking for some setting that is not in the generic linux driver that is in the Windows one. Or 4) Something else that I am not seeing. -Dave |

As of this moment twitter stock is about 10% below ($48.90) what the buyout price is supposed to be ($54.20) so it looks like a lot of major market players don't think it's really going to happen.
Or they think they can do better then 10% in 90 to 180 days.
Don't know or care enough either way but I did find it interesting that this is one of the few times a buyout has been announced and agreed to in the last 20+ years that the stock did not spend the rest of the time hovering around the buyout price.

Yeah, but with a 2% fee on the bill payments from bitrefill
I think their 2% fee is still good enough for smaller bills and it seems that you can still use Strike to take advantage of their " 5% cashback [credit goes to @Kahuna_07 on Twitter]". - Personally, I'm more worried about the time it takes for them to pay the bills ["within 3 business days"] because I had a bad experience with using a similar service in the past [locally]!Well I just too a look around and yes there are mortgage and auto loan providers there. Don't have a car loan at the moment but I will pay a CC bill and a few other other things and see how it goes. -Dave |

Yeah, but with a 2% fee on the bill payments from bitrefill and a 10% markup (no that's not a typo) fee on the VCCs from coinsbee. For the US & Canada there are better deals on the VCC. I don't know about the rest of the world. The bill payment is new thing so 2% although high IMO may or may not be average for these kinds of services. Will be interesting to see if you can pay car loan or lease payments, mortgage payments and those kinds of things. -Dave |

And the manager of the campaign is looking for a certain "tone" of posts or other things.
Do they lean a bit to the left politically or a bit to the right?
Do they tend to not start new topics and only reply?
Are they from the EU or US or Asia and although they are looking for posters from all over they want more from area "X"
And so on.
So although good posts are important I can see having a lot more criteria.

Is there a way to see if peers tried to open a channel to you but could not for some reason?
One one of my nodes only have 2 channels opened by others although there are a lot of peers.
A greater number of peers than the number of channels does not imply that someone tried or wanted to open a channel with you. Nodes randomly connect to other people to exchange the gossip information. Sorry, that was an incomplete thought that I typed. I *know* at least one person tried to open one and could not. Did not know if there were others. He did not remember the error but did mention in passing that it failed. Was wondering if it was just him or if others also could not. -Dave |

There are probably more IT people in the world arguing about which reporting software is better then there are people fighting over religion. Since most GOOD PDUs will let you pull data with just about any SNMP software I like RRDTOOL [ https://oss.oetiker.ch/rrdtool/ ] & Cacti [ https://www.cacti.net/ ] There is an implementation of cacti called ez-cacti which I think is no longer supported but should still work but was a preconfigured setup so to make life easy. No doubt others will chime in with their favorites. -Dave |

A new breech of customer data and this time it happened back in December. I wonder how many other hardware and crypto companies have been hacked but are keeping it a secret. Or even worse, how many don't know due to poor procedures & policies? Secrets may and probably will eventually leak. If nobody ever knows about it...... At least we haven't seen the data being sold somewhere. I guess they got to him in time.
Or it was sold but nothing has been done with it yet. Just out there 'fermenting' till we all forget about it because the next breach has happened. -Dave |

Rescan startup parameter removedThe -rescan startup parameter has been removed. Wallets which require rescanning due to corruption will still be rescanned on startup. Otherwise, please use the rescanblockchain RPC to trigger a rescan. ( #23123) Any reason for this? Just due to me playing with nodes all the time I actually use it a far amount. The issue at least for me is that on some older / slower devices there can be a LONG delay between when you start the daemon and it actually is ready to respond to a command. -rescan was a 'fire and forget' Either way thanks to you and all the others who work on it. -Dave |

There is also mynode http://mynodebtc.com that has a per-configured virtual machine that runs under Oracles Virtual Box. TOR is a premium feature that will cost you $99 BUT since it's running as a VM on your Mac you don't have to shell out the money for any more hardware. @NeuroticFish did a write-up on how to do it under the WSL and Debian, should not be that hard to adapt it for a Mac: https://bitcointalk.org/index.php?topic=5367296.0-Dave |

Just as a side note, if you are US based (and possibly elsewhere) you can't use ebay gift cards to buy these. I bought a giftcard on bitrefill to get one of each and they did not work. Then I read the terms https://pages.ebay.com/giftcard/terms_conditions.html: The Gift Card may not be used to pay eBay service fees. The Gift Card also may not be used to buy eBay Gift Cards, third party gift cards, gift certificates, coupons, coins, paper money, virtual currency, or items generally considered to be "bullion" (for example, gold, silver, and other precious metals in the form of coins, bars, or ingots) Oops. Guess I have to get that new SSD now instead. -Dave |

Nice catch. But now i wonder if the seller also put backdoor where he also can generate or sell the token  . Probably not, there are a bunch of free scrips out there that do the same so at a guess they are just putting the info you give them into it and selling it to you for ~$40.00 The question is are there back doors in those scripts that the original script writers put in. Reminds me of back in 2013/14/15 when you had all those alt-coin generating scripts that did a bunch of bad things. Same shit, different day decade. -Dave |

Check out https://www.parallelminer.com/ They have a bunch, no idea if they have anything for IBM and you didn't give a model for the one you have. Most of the IBM PS are made by delta. Unless you have a lot of PS you may be better just getting a complete setup instead of trying to source a rare board. -Dave |

When throwing dice at a casino the shooter has to have the dice hit the back wall of the table. The casinos want that to happen because when the dice hit the back wall they believe the dice then become fully random. Many casinos tend have the wall covered in a multi angled surface. Doing it a home, not so much if you are just throwing them on your computer desk.
However, with the availability of dice with up to 120 sides you can actually come up with some really ways to do things.

and I don't want to get asked for KYC or some stupid sh*t blocking my money in app. Then, whatever you do, don't go with Coinbase. They're the ones who started and supported this KYC claptrap. It is known that they censor transactions, treat bitcoin as non-fungible, sell all of your data to chain analysis companies etc. Obviously, they don't go well with transparency and that's why their wallet is closed-source. It won't surprise me if it contains spyware to maximize their traceability. Consider using any of the recommended non-custodial wallets from bitcoin.org instead. As others have said, all in all there are better choices. But, I will add that if there is some feature you need or coin that only they support I would not worry about using it. Off the top of my head I can't think of a reason, but you might. -Dave |
