And there can be a huge problem with false positives, since every coin has some percentage of taint to it Not mine. Every Satoshi I have were earned via mining and are/were New coins. Now for folks that buy coins, ja some coins or some part of them may be tainted.

With him being one of the major backers behind behind HalognMining (the DragonMint miners) and the ASICBoost "Defensive Patent Protection" scheme I hope to God he is NOT one of the devs that gets sponsored. He sure as hell does not need the money and has a general disdain for anything that is good or ethical for the BTC Community!

Ja. What's scary is that per the paper, "Because of this (wide availability of micro usb cables), the European Union has discussed the potential of adopting the USB Type-C connector as the standard for (delivering power to) all future devices bought and sold in its region." Great. So not only will you still need a wall wart or dedicated PD port but it will also mean that because they are physically the same, usb-c devices will have to be smart enough to know if PD or data target is plugged into the 2 or more usb-c ports (1 PD, 1 data) on the device and be sure that the data cable is a data cable vs a power only cable. Issues with the earlier Avalons caused by folks using a usb charger cable vs full up power & data cable comes to mind...

Use the "Insert Image" function isntead of posting the url. You settings look right to me, I can't tell if you have any leading/trailing spaces, so the best way to know for sure is by looking at the status page, if the pool shows "Alive" then your settings are correct. As kids would say these days, BIG OOOOF incoming. Custom firmware and Ck have a rocky relationship.
Crazy Mining is a rebranded Vnish, Cksolo pool works just fine with Vnish (Asic.to and AwoesomeMiner) so I would assume this would work as well, and might as well hit a block or two. ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) Um, didn't -ck kill off the Germany node? He's not only pointed there but at the now defunct 'normal' pool ta boot. Not the solo...

Well now... This paper from DigiKey blows that idea out of the water. While it does not expressly say that PD and data xfr is not possible the paper again pushes the idea that USB-C PD ports are primarily going to be used only for power. So, I take it that means that we will still need 2 cables to our power hungry devices - 1 USB-C PD for power, one USB-C for data. Pretty stupid if you ask me.

Well for one read this about mining in general from point-3 on down. For hardware information there is this list of current competitive hardwareTo get any sort of income you really must join a pool as solo mining is truly is a lottery with very VERY low chance of 'winning'. That said, a few key points: You MUST have very low cost electricity to stand ANY chance of not losing money. Most current miners draw anywhere from 2kw up to around 3.5 kw. Miners are HOT and LOUD! All power they consume is directly converted into heat. Think high power space heaters as loud as industrial shop vacuums and you are close... That heat and noise cannot be suppressed. A good explanation of mining can be found here and the other ares of that help file.

however there are two really large transformers inside the warehouse that may help the 480 turn into three phase 208/220 There is no 'may' about it: those *are* the 480/220v step down xmfrs. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

It's fairly common in the USA to have 480 phase to phase, and 277 from one phase to a neutral. There's usually a stepdown transformer to provide some 120/208 but then again, many things CAN run off 277/480. In commercial buildings that is.
Incorrect. In the US, 480V service is the start of what is usually called "heavy power" and usually only available to industrial areas and large commercial developments such as malls and office buildings. In large buildings it runs HVAC and is also distributed throughout the building to feed local 120/208V transformers that feed power to different areas of a building. The only common use for the direct 277V phase-to-neutral is for overhead lighting fixtures designed to accept the high line. The 3-phase of course supplies large 3-phase loads. For all virtually all other '200V' devices, they usually top out at a maximum input of 240V and WILL quickly fail when fed anything over 250V.

If people are foolish enough to believe everything they see on Social Media sites and refuse to do ANY facts checking, then they are idiots. Anyone can post nearly anything on SM sites. Why on earth do so many folks blindly believe what they find there?

Utter nonsense! I see this as an organized effort sponsored by an organized corporate entity to de-frame bitcoin. If this hospital want to genuinely help people, they should start rehabilitation program to come out of facebook addiction. This facebook addiction is actually harmful for the society which only fills up company's account without fetching any personal benefit.
Agreed! The rampant addiction of folks feeling the need to constantly txt and use other social media platforms is a far bigger problem. Hell, each year many people are killed because the idiots walk into traffic while texting. The problem is bad enough that several cities have installed warning devices that flash in the sidewalks at intersections along with location-based apps that trip the phones to display crosswalk warnings.

^^ is correct, Google cannot shut it down, just at best they delist it from search results or tag it with a warning. Since for now the site is gone we have to assume the site host (OVH) acted on complaints and took it down.

Narf... I had used that site a couple years ago to make my Vanity Address, never really used the address but I do see that someone deposited $15 into it on Sept 23 and that the address along with many other folks addresses was swept clean yesterday as well https://www.blockchain.com/btc/address/1Fuzzyk398kDWVjuC5qPX5v6CjSkvbgAbdCrunching a new address OFFLINE for tips/donations as I type... edit: done, took 4 hrs to generate new 7 char address offline

Kano is vocal about the GPL issue in almost all of the aftermarket firmware threads. Just check them and every few pages he brings it up again and again. The one exception is BoS from the folks at Slush and that is because BoS is a clean re-write of the software and is not using any cgminer code plus most of the BoS code is published as open source.
As for Bitmain and other mfgr's using cgminer without posting their code, only Canaan has lived up to the source code requirements so ja BM, MicroBt and others are also in violation but pretty hard to go after them about it...

I wonder what the actual rules are for what US customs calls made in China. If all they have to do is send hashboards separate from the main body to Malaysia and have them just plug them together to bypass the tariff, I'd think all of the other manufacturers would have jumped on that...
Not positive but am pretty sure it takes more than sending a plug-together kit of parts to get around the tariffs hence my guess about the boards being stuffed in Malaysia as well PSU's being made there as well. Someone needs to check the Customs category breakdown on them.

As far as I know, Bitmain doesn't make any mining gears in Malaysia, it's probably just a sorting hub to reduce import/tax costs for countries that aren't so friendly with goods coming in directly from China, Incorrect. The Trump Tax tariff and ones from a few other countries forbid that by using Country of Origin as the deciding factor. That means where the miners are assembled so BM does have at least 1 assembly plant in Malaysia that does at least final assembly of them using parts made in China. Given the quality issues they may also stuff the hash boards there...

Bitfury has been doing that for ages. It remains as the most effective way to cool the miners and eliminates the problem of miners being excellent dust collectors. Even in a data center with fairly clean filtered air coming in, because of the very high airflow through a miner the heatsinks/fans in them get very dirty very fast. Then there is the issue of hundreds/thousands of fans that WILL fail sooner or later. With the 2-phase cooling from immersion in Flourinert, only the outside 'dry cooler' heat exchangers gets dirty and they pretty much don't care. Use magnetic-coupled sealless pumps to push the fluid around and you have a pretty much maintenance-free setup.

Looking at the usb-c PD dev boards out there I am not seeing combined power & data from anyone. What's surprising is that the datasheets only talk about usb-c PD replacing power via barrel connector with zero mention of data. What the heck is the advantage of that? Only thing I get is 1 less component because no power jack. Aside from that you are just replacing one brick with a different kind of one. This from Cypress Semi and this from Infineon are typical of what I've come across so far. you still need a way to insure proper volts to what ever device you plug into it.
That is negotiated by the usb-c PD chip and the device you plug into it. The pd chip defaults to 5v out and only after handshake does it raise voltage out to whatever the connected device wants. What *is* interesting is that the standard I linked to earlier says that usb-c PD is a 2-way connection - whatever is plugged in can be both a power sink and if needed become a power source. Think a battery pack: It can be connected to a hub for charging along with a spinner portable HD for data. When the drive needs power to spin up if the hub cannot supply it the battery pack will. Good talk about that is here. re: safety, all of the pd chips I've looked at so far have comprehensive short circuit protection for both fire and data safety.

Poking around amazon for "usb-c PD" brings up several chargers & power sources such as this from Anker but nothing that is also a data hub... That despite this USB-C PD standard mentioning use with HDD's & printers implying not just supplying power to them but also being used for data over the same cable. Go fig... What is interesting that in 20v output mode USB-C from a wall wart is good for up to 100w which is how it powers the newer laptops and tablets. Lenovo has been doing that for a couple years on their tablets, even those using micro USB-B connectors. My Yoga tablet wall wart outputs 22V when powering the tablet but drops to a safe 5v up to 3A when connected to charge a 'normal' usb device like a phone. Well, usually drops to 5v: I did once have a vape battery go Dragon mode on me when charging with it. Worked fine many times and then 1 day - FOOM! a 2 foot flame shot out of the battery for about 2 sec followed by release of all the Majik Smoke. My guess is that the charging dongle failed delivering full power to the battery. Just very glad it was sitting on a solid surface away from anything easily ignited...

My guess is that high power over USB-C is mostly an optional setup rather like PoE is for network devices - a special hub will be needed that can supply the higher voltage & power.
In a way I can understand the lack of mobo's with built-in PD bus - no liability for failures caused by non-compliant devices plugged into the USB-C port going 'poof' or worse. Keep it at 5v and even the dumbest charger/device should be happy...
