1  Other / Politics & Society / Let’s say I’m a Russian soldier... on: March 13, 2022, 01:12:33 AM
A little humor.


Let’s say I’m a Russian soldier in Ukraine, and I’ve been freezing my tiny putin off for the last 3 weeks, not able to sleep in my tank because I’m afraid of a special delivery from UPS (not United Parcel Service, but the Ukrainian Pummeling Soldiers).

I gave up my cell phone months ago, I have no idea where I am, and 3 of my friends have been killed within feet of me.

I ran out of toilet paper, hell, I ran out of toilets themselves weeks ago, and my hands smell bad.  

I  haven’t had a shower in 2 months, the one meal I get every other day isn’t even cooked, and my sarge, Boris, is starting to look like my smoking hot girlfriend Irena:



I'm not very happy and I don't know how it will end.



Communication is everything.

Do these Russians solders know:
-   How to surrender
-   Where to go to surrender
-   What financial rewards are available for selling my tank?
-   Who offers escrow service so that I can sell my tank to paxmao
-   How can I tell people at home the bad things I’m doing.
-   How to tell Serbsky Center that KingScorpio has escaped

Drop some prepaid cell phones with a 1-800-Sellmytank number pre-programmed.

Drop some Leaflets “How to get rich quick – sell your tank”



Give them directions, give them options

- How to communicate back to the Russian people (cells phones) get them texting pictures to mom
- Give them directions on how to end their situation
- Leave billboards with 1-800-Surrender phone numbers



Good Luck Ukrainians!

2  Other / Meta / Mprep battling virus posts on: February 13, 2022, 10:24:54 PM
I’ve been watching mprep (I think) battling spammers posting a virus in altcoin mining at the pace of 1 post or more per minute for the last few hours.

Looks like someone has access to a long list of new and old ID’s.

Amazing how fast mprep (?) is hammering these!

Is there a place to see how many posts have been deleted there in the last few hours?

Brings to mind, are there any stats for spam post deletions, frequency, etc?

Edit.
 
Some of the virus posts have accounts originating in 2017/2018, and I’ve seen at least one that had a lot of bounty history until the virus post.
3  Alternate cryptocurrencies / Mining (Altcoins) / Altcoin Mining: you WON’T pay for that card (with assumptions) on: January 13, 2022, 01:38:44 AM
Altcoin Mining: you WON’T pay for that card (with assumptions)

So, I’m going to take the position that you will NOT make your money back with altcoin mining.
Instead you will have to ‘gamble” to make money.

Change my mind.

Here are my assumptions:
1)   The price of the coin stays fixed (yah, yah, who knows what it will do?)
2)   Mining Ethereum
3)   Electricity is .20 per kilowatt USD
4)   DIFFICULTY continues to rise as per this website (3.8% per month, 29% in the last 90 days) https://www.coinwarz.com/mining/ethereum/difficulty-chart
5)   I’m buying an A4000 at 1499
6)   I’m not counting the value of the card itself (I don’t know what it will be worth in the future)
7)   Total rig cost for 5 cards is about $7500
8 )   Assuming we sell Eth for USD each month


    a4000
Card Cost   1499
Qty   5
Sub total   7495
Tax   449.7
    7944.7
Hash Rate   60
Hash Total   300
Day income per hash   0.055
Daily Income   16.5
Watts Per card   123
Rig Watts   100
Watts/hour   715
Watts/day   17160
Electric cost/killowatt   0.2
Cost/day   3.432
Net/day   13.068
ROI Days   607.9507


It will take 608 days to ROI on the A400 (not counting difficulty).
If I can get the card for $450 dollars instead of 1499, ROI is 182 days or 6 months.

BUT………..

Difficulty is eating away at your income every single month.

Right now it is reducing your net by 3.8 percent per month.

Buying 5 cards, electric to run the rig, we clear  $13 dollars a day in the first month.

But difficult increases each month.
By month 42 we actually start losing money on the rig (difficulty increases).
The closest we come to ROI is at 42 months, and we still owe $1617 dollars




Difficulty is killing your mining investment.

I maintain you would have been better off invest in a fund Like VTI.

Over the last 5 years a $7500 dollar investment would have grown to $17,000.

But….

Here is where we all are gambling.

If you took that $7500 and invested in ETH 5 years ago (forget mining), you would now have $1.6 million dollars.
It’s not the daily income from mining that makes the money, we are all hoping on the coin going up in price by 100 times.
So,  mining isn’t the answer, investing and holding is a better choice…..

4  Other / Meta / Merit Generation by subgroup using Ratimov's data on: January 12, 2022, 04:05:52 AM
Looking at Ratimov’s post here: https://bitcointalk.org/index.php?topic=5380683.0

It would be interesting to see how much merit is generated by subgroup and how many UNIQUE people actually are passing out data in each subgroup ( in 2021).

I would think someone has already run the data.

Using Ratimovs data in the first 4 columns, is there a place to see the three columns on the right that I added?

5  Alternate cryptocurrencies / Mining (Altcoins) / Malware WAR in Altcoin mining subforum on: December 13, 2021, 02:43:57 PM
I spent the last hour or so in the Altcoin Mining subforum reading new posts (procrastinating), and ran into  "LHR" malware posts.

In the span of about 1 hour I reported 28 cases (28 posts in the hour were LHR malware).

I never realized it was so bad!

During that time period there were just 4 VALID posts related to mining.

4 good, 28 malware.

They must be successful (making money) as it must take time to create these ID's

Question:  Is it worth reporting these to the moderator?  


6  Economy / Service Discussion / EBAY bans sales of ASIC Miners, I filed a complaint (I won't win) on: March 28, 2021, 12:18:27 AM
Maybe this is old news, but today I tried to sell a Whatsminer M3 on Ebay this morning.  It got rejected stating that managed payment users (EBAY is forcing everyone to managed payment) are not allowed to sell virtual currency.

I argued (see transcript below) that I was selling a computer and not virtual currency, and that there were thousands of ASICS for sale. 

Basically Ebay Person 3 said :Not for long, as everyone is converted to managed payments, the selling restrictions grow tighter, and miners will go away..

Ebay person 3 agreed to file a complaint for me, but would not give me an email address.

They did give me a snail mail address in case anyone REALLY wants to complain with me.  It is at the end of the transcript.

Anyone else been cut off?

Toughit
Thank you! How can I help you?
Ebay person
Im trying to sell a Whatsminer M3, for which there are about 6 for sale. It is a bitcoin miner. When I try to list it it says I can't because of managed payments.

I'm sorry to hear that you are unable to list this item. Let em check how we can help you
Ebay person

Upon reviewing, Sellers enrolled in managed payments are not allowed to list the following items: Auction services Gift cards & coupons Lodging, timeshares, vacation packages, and car rentals Tickets for travel, events, or experiences Virtual currency Wine
Ebay person

I’m not selling virtual currency,
I’m selling an electronic mining device
and there are others listed!

WE apologize since the only possible reason is that those members are not yet under Managed Payments.
Ebay person

there are thousands of bitcoin miners for sale such as the antminer s9
A3, L3, etc.
I believe ebay forced me into managed payments, right?

I need to ask a colleague in another department to step in on this issue. They specialize in dealing with this type of situation, so they'll be better able to help you resolve it. Please stay on the line and  I will connect you over.

Thanks Toughit. One moment please
Ebay Person 3

These items are listed under virtual Currency Toughit which is a blocked category with managed payments i am afraid
Ebay Person 3

but they are computer equipment, not virtual currency like bitcoin or ethereum. this is a computer!
Would it be OK to list it under electronics?

Allow me to check.
Ebay Person 3

Thanks Ebay Person 3

The correct the sub category for miners is still under Coins, Coins > Virtual Currency > Miners which I am afraid is a restricted category under managed payments I am afraid. A quick review of similar listings like this Toughit shows me that multiple listings similar to this have been removed also.
Ebay Person 3

so it is restricted Because it mines bitcoin, not that I am selling bitcoin?
How about this one, it is SPONSORED, so they pay you extra to sell it. 114737140810, there are 1280 similar to this listed right now,
all under the miner category. Why do you allow others to sell?

Yes, unfortunately the item itself does fall into the Coins > Virtual Currency > Miners category which is restricted on Managed Payments.
Ebay Person 3

These other sellers may not be yet activated on Managed Payments yet so they do not get the automatic block but we do have teams actively monitoring for such listings and they are being removed and accounts being restricted for repeated violations.
Ebay Person 3

I will be sure to pass your information on Toughit. eBay are actively looking into these restricted categories regularly and updating them on a regular basis too.

7  Alternate cryptocurrencies / Mining (Altcoins) / 3060 Hash rates - a couple actual hash rates and a small ROI chart- NVIDIA Fail on: February 27, 2021, 03:57:14 PM
I received my 3060 two days ago, I paid $412 with tax at Amazon, purchased last week in a pre-sale.

Installing was no fun, it would not work on my Windows 64 1709 version, even after fully updating.  I ended up formatting a new SSD with the latest windows.

NVIDIA does throttle the Ethereum hash rate. Dagerhashimoto mining starts at 47 and then it quickly drops down to the mid 20’s.  

I managed to get about 26mH steady in Nicehash using PhoenixMiner.

Based on Nicehash prices today (which have dropped 40% from Monday), the card would make $2.12/ day.

On Nicehash Octopus I am mining at a steady hashrate of 44.3 (42.6 at Nicehash) with 125 watts (as reported by NBMiner).  Yesterday that was bringing in $3.80, today about $3.20.  

The first chart shows breakeven (ROI), not counting electricity cost or taxes. (Pink line is Ethereum today, the rest are Octopus).

Mining Ethereum at 26mH at $2.12 (today), breakeven is about 193 days (Pink line).
Mining Octopus:
      $4.00/day, ROI is about 102 days (blue line)
      $3.00/day gives ROI at about 140 days (grey line).

Either way, a 3060 at retail price gives a decent return, not stellar, but worth it.  All depends on what this market is doing.

In other words  NICE FAIL NVIDIA!






Update:  Octopus mining fluctuating, Making $4.27/ day at the moment, about 96 days ROI...




Edit 2: Nicehash dashboard reporting $7.47/day (this jumps up and down a lot) - ROI just 56 days! (dreaming a little, it won't stay at this peak but hope they read this at NVIDIA!)

Anyone else unable to log into Nicehash?
9  Alternate cryptocurrencies / Mining (Altcoins) / Stop mining your ASICS (Avalon 741) on: March 18, 2018, 04:04:49 PM
It now makes more sense to stop mining your Avalon 741 and just purchase Bitcoin instead.

You would be better off spending the money you would use for electricity to run the miner, and just buy coin instead.

The point of stopping the hardware varies for everyone and is based on:
•   Price of electricity
•   Pool fees
•   Hash rate
•   Bitcoin difficulty

The price of hardware does not factor into this decision to mine or not mine.

I have Avalon 741’s, so my variables are:
•   7.4 ths
•   $.15/USD/ kilowatt Electricity cost
•   2% fee at Slushpool
•   $135/month of electricity burned/month for Avalon 741

The chart below shows that any time the price of Bitcoin drops below $8440, I should turn off the hardware and spend the money saved on electricity to purchase Bitcoin instead.
www.whatotmine.com was used to calculate the prices.


 

How much bitcoin to buy while the Avalons sit idle?
It works out to around 0.00053318 worth of Bitcoin per day per Avalon. ($135 electricity/$8440 bitcoin breakeven price/30 days in a month).

This ONLY works if you have the discipline to actually buy bitcoin when its below the breakeven point.  Obviously, if you don’t buy, you will miss any rise in price of Bitcoin.

The chart below shows the price to stop based on electricity cost (given the other assumptions).
 





I just turned off my Avalons.
10  Alternate cryptocurrencies / Mining (Altcoins) / Ahashpool coin maturity: chasing the top coin, and why I shouldn’t (maybe) on: March 16, 2018, 04:05:15 AM
I’ve been mining on Ahaspool for a month or so without really understanding the mechanics.

I decided to figure out exactly how it works after I noticed something strange while working on a different miner:

Mining has not been good lately, I think the top coin 3 days ago was x17 at about $11. (4 1080 ti’s)

All of a sudden Denarius shot to the top at $37/day, and my computer locked on.

Mining lasted for about 13 min, and then Denarius dropped down to $8.50 or so, putting X17 back on top.

2 min later Denarius dropped all the way to $2.27.

I looked at the dashboard and found that all of the mined Denarius still had to mature before hitting the exchange.

I figured it would be good to know how long it takes each coin to mature after it gets mined, so I collected data for a few hours, averaged a few things, and came up with the table below. It shows the time to maturity for each coin. Missing a few coins I am sure.

The time to maturity should be based on the network (not the pool) hash rate, and should be pretty stable day to day. (maybe not for smaller coins).

These values are probably not 100% accurate, but  close enough for me.

                               Blocks To maturity   Min to Maturity
tribus        Denarius       30                        20
neoscrypt  Feather           101                      50
skein        AuroraCoin        81                        65
xevan   Solaris           60                         67
x17   Verge                  140                        78
nist5   Bulwark                67                        111
lyra2v2   Mona          101                       125
x17   SHIELD                 260                      203
skein   Unitus                 181                      209
lyra2v2   VertCoin         101                      239
neoscrypt   Innova        101                     250
neoscrypt   Desire        101                    377
neoscrypt   Vivo               101                    556
xevan   BitSend         250                    968


So looking at my chart, Denarius takes about 20 min to mature.

Lets follow the scenario for me:
•   I mined for 13 min with Denarius at $37
•   Denarius dropped to $8
•   I stopped mining
•   Denarius dropped to $2.27
•   My shares matured
•   My shares went to the exchange at $2.27 NOT $37

So…  I mined xxx Denarius, thinking I get a high price, then it turns out it sold/exchanged to someone/somewhere at a much lower price.

Of course, this is the same for every coin, you mine for a while, then the price drops, you stop mining, and then a while later it hits the exchange. Might be higher, might be lower.

I have a theory.

I have a lot of questions
-   Optimum interval time
-   What exchange do these numbers come from
-   What coins should be eliminated from my pool search
-   How often should I analyze adding coins back in
-   Is there a pattern to which coin is on top
-   Who is the mined matured coin sold to
-   Can this pattern be manipulated? (force something high, then drop the price) (why)
-       Do coins stay at the top longer than their maturity time?
-   Etc.

More to come.
11  Other / Off-topic / Does anyone here work at one of the “Windows Tech Support” scam call centers? on: March 16, 2018, 01:01:22 AM
With over a million users the odds are high that someone works in one of the 'Windows Virus" scam centers.

I just had my 3rd call in the last two weeks from the “Windows Tech Support”  center.  It seems that my computer ‘is full of viruses’ again, and they needed access to my computer to fix it.

Sometimes I play along, like asking them how they could know, and what is my IP (192.blah.blah) they always say.

Then I ask them why they work in a scam call center and surprisingly they insist they are not a scam and continue to push.

Depending on my mood, I might just hang up, but when I’m feeling good I like to play.  I usually start insulting them with the worst things I can think of like questioning their moms choice of a husband (donkey or mule).  Sometimes they hang in there for a while.

The best one was a guy speaking fairly clear English, I asked him what kind of a f*ing a*hole he was, he replied “I’m the kind of f*ing a*hole that calls you every week for the last 6 months”.  I started laughing and hung up the phone.

The one last night was a woman, she held up for a good 3 min taking my increasing insults, insisting the whole time that it was not a scam.

So,,,two questions:
1)   Whats your favorite way to mess with them
2)   Have any of you worked in one of these scam centers

13  Other / Meta / Toughit merit source application on: March 11, 2018, 12:32:52 AM

If you want to be a merit source:
 1. Be a somewhat established member.
 2. Collect TEN posts written in the last couple of months by other people that have not received nearly enough merit for how good they are, and post quotes for them all in a new Meta thread. The point of this is to demonstrate your ability to give out merit usefully.
 3. We will take a look at your history and maybe make you a source.

I am applying to be a merit source. 
My  focus would be  mainly on the altcoin section:
•   I would run a promotion to try to get people who have sent little or no merit to start using it
•   I spend time in some of the mega threads, there are under merited posts buried inside
•   I mine Bitcoin and Altcoin, and appreciate the hardware side

These are some of the posts I believe could use more merit:

https://bitcointalk.org/index.php?topic=2975942.msg30581596#msg30581596
KYC is for banks and official institutes not for ICO which any random online can start. It's data harvesting and I for one refuse to just hand over my personal info to some random online. No wonder people us fake ID. I could see this was going to happen a mile away. KYC is useless online. Proper KYC is like when you open a bank account. You go in and actually meet a bank representative and not just trust some online only organization. You then sign legal documents and submit your ID and proof of residency in form of your electricity bill for example. This can't be faked and your info cannot be shared or you can sue the bank and win.
Let me make this clear. I have no issue in using KYC when it is fully legal and sanctioned. But I will never hand over a KYC when I can't meet the person asking for it. If you investing large amounts of money you should meet face to face with the people behind the ICO anyway. I don't see why anyone would give money to someone online and then still give them their identity. There is no reason for an ICO to ask for KYC and they are just making excuses as to why they ask for it. It has nothing to do with tax. You must fill your own tax form every year end yourself and declair your expenses and your profits.

How long will it take till criminals decide to use an ICO and harvest our personal info and steal our identity? You will be relaxing having a good Sunday afternoon when suddenly a police man knocks on your door and wants to talk about crimes committed under your name. Identity theft is serious and a problem in every country. Stealing someone's identity is like free money because they can abuse your identity to take loans and all sorts of things under your name and your identity.
In my country if I steal someone's identity I can do all sorts of bad things. I can open cellphone contracts and contracts with shops and buy video game consoles tv sets and even furniture all under the name of the person I stole the identity from. I could run scams and use your identity and then you get harrassed and stalked online because people think you ran the scam. (Please not I am not an actual criminal I'm just saying if I were one what power having your identity would give me)

People please think before just giving out your personal info. Think about your safety and the safety of your loved ones. Your family love under the same roof as you do and now how many icos know where you live? Just knowing that, that many people know where I live makes my skin crawl.

So please people don't give your KYC because some nitwit online promises to pay you. Even if you are paid it means nothing. Your info can still be abused and there is very little you can do about it since you handed it over willingly. You have no legal protection at all. I don't even think it's legally bound to be honest.

What criteria do these KYC corporations use?  I mean the info they use must be public correct?  So if everyone has access to the same information as they do the entire premise of KYC seems to be a sham.  I almost sent mine in for Polymath.  Thank god better judgement prevailed.


Their person info should be public if they plan to ask for KYC. After all you won't give your KYC if they won't give theirs right?
You are correct.

It seems as though the community was willing to give up the key principle of crypto (privacy) and the process they submitted to wasn't even legit with seemingly a large portion of the people simply sending in fake docs.  I personally boycott all projects asking for KYC so my information is safe however crypto is in major trouble if we have swarms of people willing to give up their data for a few bucks.  The people who put profit before the movement are despicable and we and our ancestors will continue living in monetary slavery to the elite do to their greed.  Great job guys and thumbs up to everyone who crashes this KYC process.  Modern day heroes in my book.

Good for you. I name and shame any ico asking for KYC. Another tactic is as we saw with casinos not paying out till you show KYC the ICO will not pay bounty if no KYC is shown. This is theft because they dent payment.

Send in no real data for KYC.  Don't use a real person so no ones identity was stolen.  Be from a backwards country. 

Do you think they know the complete information from an individual living in a remote part of the world?  Give me a break. 

Way more risky to send in the real thing.  At that point your legal troubles could be Murder, Terrorism, Hijacking, kidnapping etc. 

Not many people in jail for claiming they are from the Democratic Republic of the Congo.  Good luck finding information on Mr. Migushu.  They will simply pass it.  You all see what a complete cluster fuck the KYC turns into right?  Do you honestly think it was running correctly?   Was everything top notch and smooth.  Nope its a complete cluster f*ck. 

Exactly! People can perform criminal acts under your name.



One  of the main reasons why Cryptocurrencies is famous and preferred is the fact that it provides anonymity. the documents such as passport and ID, required during verification already goes against one of the integral features of the trading platform,However sending fake ID for KYC seems to be a loophole hackers are exploiting. it also leave s a big concern of=n the security of the users accounts,

I share the same worry, KYC might be the blueprint for the fall of crypto currency.

Exactly!! Crypro is ment to be anonymous. It's like using a VPN but for money. The government already has so much control. We are not criminals we are simply people who want control of their own money.

Very low maintenance, ever since I added automatic restart scripts on a 24 hour interval and watchdog scripts to restart and log automatically whenever it notices 0% GPU use or network disconnection. I take a little hit while it restarts though.
Care to share more about these scripts?  I'd find that very helpful.  Thanks!

I have a script called autoexec.cmd start on logon using the Task Scheduler. Autoexec.cmd is a little take on the good times of the past. It will start the miner program and watchdog. I choose the miner program I want to use by commenting out the others using the REM command. After it has started the miner, it will run C:\Tools\watchdog.cmd which will start monitoring that the system is on the network and the GPU's are doing meaningful work. The Autoexec.cmd script will then hibernate (but still stay running) for 24 hours before it restarts the system. All this while watchdog is on another command line session monitoring the system.

I've written these scripts to work on Nvidia mining rigs. They can be freely copied and modified as needed.

C:\Tools\autoexec.cmd
Code:
@echo off
echo  .---------------------.

Below is a (VERY CRUDE! ) Smiley script that logs every bootup and tries to ping preconfigured IP addresses 8.8.4.4 or 8.8.8.8 every 30 minutes. It will also use the NVIDIA configuration utility that comes with drivers called "nvidia-smi.exe" which tells the watchdog if any GPU is at 0% use. It will try a couple of times and restart if any GPU stays at 0%. Any errors that occur it logs. It's a bit botched together, but works great in my use.

The below example script will set the overclock settings for 5x GTX 1060 graphics cards on the console using nvidia profile inspector. It is called from autoexec.cmd, so that the overclock settings are set at boot time. Same functionality can be achieved with Nvidia Afterburner, but one of the Nicehash miners would override/reset my OC settings, so I started using scripts instead. Additional bonus is, that I can run these in a timed loop every hour to "remind" the miner computer of the correct OC settings.

oc_zec_effic.cmd

@echo off

https://bitcointalk.org/index.php?topic=2949541.msg30305802#msg30305802
Hello All,

Just wanted to share my funny experience with these cards I purchased around a year ago.

The cards Im talking about are the Gigabyte RX 570 Gaming 4G: https://www.gigabyte.com/Graphics-Card/GV-RX570GAMING-4GD#kf
They are pretty much the worst cards I got for mining, even though I bought them early on for 160$ each, and I got 30 of them.
At first they were great, amazing value for money and ROI, elpida memory, they do 29.5mh/850mh eth/dcr; and 900 h/s on cryptonight.

They worked great for 10 months, and then the fans started failing; these fans can not handle dust at all. They are very poor in cooling; and unless I set the fans at 80% or more, the gpu temps would easily reach 75C.

The funny thing is that half of my cards would have the rear fan failing, either completely stop working, or work at a much slower rpm; to the point that I had to only mine cryptonight due to the lower power requirement for the algorithm compare to dual mining.

So I got this idea..

A week ago, I purchased these fans: https://www.aliexpress.com/item/Brand-Original-Delta-AUB0812VH-pwm-DC12V-0-41A-80mm-computer-cpu-case-axial-cooling-fan/32541022969.html?spm=a2g0s.9042311.0.0.Fy7LDH
And these splitters: https://www.aliexpress.com/item/SATA-Port-to-10-Way-12V-3-4Pin-Computer-CPU-Cooling-Fan-Splitter-Hub-with-PWM/32842778420.html?spm=a2g0s.9042311.0.0.Fy7LDH

Removed the shroud and fans from the gpu, and stuck the new delta fans I got on the heatsink (using some metal wires, and a bit of clamping).
and this is the result
https://image.ibb.co/hSBvY7/IMG_20180213_WA0006.jpg

Currently, out of all the cards I have; Nitro+ Limited Edition, XFX GTS Edition, Nitro+ 570 8GB, and Powercolor Red Dragon golden sample; these cheap elpida cards are my favorite xD

Temps on the gpu are at around 39C under the same conditions, and they consume less power (compared to the original fans, 12v @0.5A, the new ones are 12v @0.41A).

So I lose the warranty, but I've already recovered their cost and much more, and they still run perfectly, so I am very happy Cheesy

Now im thinking to do the same for all my other cards, and probably turn one of the AC units I got off to save on electricity


https://bitcointalk.org/index.php?topic=2866608.msg29430200#msg29430200
I thought I'd share this with everyone since I think this is a problem we can all relate to.  While it would be nice to have a networked PDU, they are quite expensive... even on the used market.  So I thought about it and came up with this solution.


I'm sure we all have a rig or two where it may work fine, but every now and then it needs to be rebooted.  It always seems to happen at the worst of times... like when you are at work... or out of town.  Trying to get your spouse to reset a rig over the phone can sometimes be just as frustrating as when you are away and can't do anything about it.

I also use Awesome Miner, which is fantastic, and can do a lot of automation to keep your rigs running.  But if your rigs need a hard reboot, the only real solution is to "pull the plug" and reboot.  Awesome Miner has "rules" that you can define to watch for triggers like an offline miner, hashrate thresholds, dead GPUs, and a lot more... and then perform an action.  It's kind of like an IFTTT (IF This Then That) solution for mining.

IFTTT... hey wait a minute... I could use the online service IFTTT to control a smart plug.  I could have Awesome Miner watch for some condition, then send a signal to IFTTT, where in turn IFTTT could turn off and then on a smart plug.

I started out with a Wemo Insight smart plug that I had laying around, and after a bit of tweaking, I got this working well.  The problem is that the Wemo Insight smart plug is only rated for 120V, and all of my miners run off of my 24 amp 220V PDU that I got for real cheap off Ebay.  I then trolled around to find some cheaper parts to do a 220V equivalent to the Wemo Insight smart plug.




Puwaha's Poor Man's Networked Power Distribution Unit
(or PPMNPDU... nevermind, that's a bad acronym)

Parts you'll need:
  • Cheap 220V PDU from Ebay (I'll let you find these to suit your liking. You could even do this with 120V PDUs)
  • Cheapo 240V capable Smart Plugs like these at Amazon (https://www.amazon.com/gp/product/B078CPYQYS/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
    )
  • My PDU uses C14 connectors, and the Smart Plugs are 5-15P, so you'll need some good C14 to 5-15R adaptors like these at Amazon (https://www.amazon.com/gp/product/B004OC579E/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
  • Good quality 5-15P to C13 power cables.  These are your regular power cables that come with every power supply you've ever bought... you probably already have a few... so free!
  • IFTTT account (it's free)
  • Smart phone to setup the smart plugs (Smart Life app, and IFTTT app)... not free, but you probably already have one... so free
  • Awesome Miner... it's free for up to two "miners" to give it a go, but easily worth the license cost in other feature you need to cover all your miners

Note:  if your setup requires the C14 to 5-15R adapters, do not get the crappy 18AWG 1 foot "monitor extensions".
  The wires are not meant to carry high amperage that your rigs usually require.





Now, to put it all together.

First thing, go setup an IFTTT account.  You'll need that before integrating with Smart Life.

Let's go ahead and setup your first Smart Plug.  If you didn't pick the ones I did above in the Amazon link, just make sure they are compatible with the Smart Life app.  This is pretty simple to setup.  I suggest you do them one at a time so you can mark them with a pen, and edit the entry in the Smart Life app... like "Plug 1", and "Plug 2".

After setting up the Smart Plug in Smart Life, give it a few whacks to make sure you can turn it off and on.  In the Smart Life app go to Profile settings and click Integration.  Select IFTTT, and it will give you further instructions on how to integrate.  You'll need to sign in using your Smart Life account to integrate.  You can either use the IFTTT app on your smartphone, or the IFTTT web page... same results.

It's time to build the first IFTTT applet.  Go to your IFTTT app or webpage and click on "My Applets", then "New Applet".  You are now going to setup a trigger (the "This" in IFTTT), and then an action (the "That" in IFTTT).  Click on the +this logo... you will need to choose a service.  Type email in the search area and then click on the email logo.  Choose the "Send IFTTT an email tagged" option.  We want the tagged option, you'll see why in just a second.  This trigger will kick off when you send an email to the trigger@applet.ifttt.com with the tag that you supply.  Our first trigger we will setup will be #plug1off so put that in the field where it says tag, then click create trigger.

Now, we need to add an action to the applet... so click on the word +that logo.  Now search for Smart Life, and then click the Smart Life icon.  You'll see a couple of options to turn a device or group on, and another to turn a device or group off.  If you think about that for a moment, you may realize that you can group smart plugs together in the Smart Life app on your phone, so you could control multiple plugs with some of these steps.  But for now, we will just finish setting up the applet for our first smart plug.  Since our trigger tag was #plug1off, then we need to click on the option to turn a device off.  IFTTT then will present you with your drop down list of Smart Plugs that you setup in the Smart Life app.  Since this is our first one, we will select Plug 1 and click the create action button.  Finally, click the finish button, and you've just created your first applet in IFTTT!  Make sure it's turned on.

Repeat setting up a new applet in IFTTT, use the same trigger of "email" and use a new tag called #plug1on, and an action from Smart Life to turn on a device or group.  Select your Plug 1 device and finish the applet steps.



If you've never used Awesome Miner before, the bare minimums you need here are a pool, a managed miner, and a rig.  Once your rig is being controlled by Awesome Miner, you can automate it with a new user-defined rule.  There are some built-in rules to give you some ideas of what you can do, but for our networked PDU concept, we will create a new one.  First, go into the Options, and under the Rules section go to the Email & SMS section.  You'd want to setup your email account here anyway, for notifications from Awesome Miner in general, but the most important part is that you use the same email account that you used to setup your IFTTT account.

You see, the IFTTT applets you created are expecting an email from your email account.  If you use the same email account in Awesome Miner, then when you setup the user-defined rule to send an email... it matches... and the trigger is set.

Now that you have Awesome Miner setup to use your email account, go to the Rules section in the Options in Awesome Miner.

You'll give it a fancy name like Plug 1 Reset.  If you have more than one rig, then click the "only apply to selected miners", and select your rig that will be connected to the Smart Plug.  Now, add a trigger for this Awesome Miner rule.  If your rig crashes in a way so that it doesn't respond to pings, then make the trigger to be a Ping (on timeout) function.  In my case, I chose to make my trigger "activate" if the rig isn't responding to pings after 9 seconds.  There are other triggers you could use, and you can even stack them for different conditions, either selecting the "Match all" (for an AND function), or the "Match at least on" option (for an OR function).  Sounds complex?  Nah, it's easy.

Finally, you need to set an Action in the Awesome Miner rule.  In our case we are going to stack a bunch of functions to be run in sequence.   The first action is to send an email to the IFTTT email address (trigger@applet.ifttt.com) with a #plug1off in the subject line.  Then I put a Wait action for 10 seconds.  Then put another email action to send an email to the IFTTT email address with a #plug1on in the subject line.  Finally, I put 6 individual wait actions for 60 seconds each.  It basically runs like this:

If no response from IP address for 9 seconds then
    Send and email with #plug1off in the subject line
    wait 10 seconds
    send another email with #plug1on in the subject line
    wait for 60 seconds
    wait for 60 seconds
    wait for 60 seconds
    wait for 60 seconds
    wait for 60 seconds
    wait for 60 seconds

You need the waits in there between the off and on action to give your rig a chance to fully power down.  You also need the waits in there after the turn on action so that your rig has a chance to boot up and start responding to pings again.  I put six waits of 60 seconds each which is plenty of time for an SSD rig to boot up and start responding to pings... but it also means that the Awesome Miner rule won't run again for 6 minutes in case something is wrong.

Here's a quick shot of the Awesome Miner rule setup:



If you click the option in the Awesome Miner rule at the bottom to "Support manual activation" then you can run the rule actions at will from the main Awesome Miner mining rig list under the Actions dropdown.  And if you have a license that allows a web page interface for Awesome Miner, then you can remotely trigger this rule at will while you are away.  That's fine and all... and could be good for getting something unstuck. 

The whole point of using Awesome Miner is to allow your rigs to keep mining, and it allows some pretty incredible automation.  Couple Awesome Miner's already rich feature set for automation with Smart Plugs and IFTTT and you've got Puwaha's Poor Man's Networked PDU!


There's probably a lot to absorb here, so I'm more than willing to answer any questions or help you out.

Hello.

I want to share with you a simple program to automatically hard-reset your machines if they got stuck.



I'm using Raspberry Pi with 5V relay but you can use any other mini-computer as well (Beaglebone Black, Orange Pi & etc.). I will add better instructions with pictures soon.



Logic is: Ping machines every 33 minutes. If there is no response - Hard-reset.

Just download the binary file and edit the config.json

Soon I will add web interface for statistics

Additional information and basic instructions are available on github

Guys, the idea is to bring all 1080ti owners that been doing lot of test on miners & pools.
every month the profit drop because of the difficulty, so let's see how much profit you can get & shear to discuss...

POOLS
NiceHash
External Payout 3%

*super easy to use
*I quit because of high fee and low profit

1 1080ti profit: TBD


Minig Pool Hub
1.1% total fee = 0.9% pool fee + 0.2% exchange

I like it because...
*low fee
*you can mine altcoin and exchange to any coin
*control the daily profit
*many algos for autoswitch or mine the most profitable coin in a algo

1 1080ti profit: TBD


ZergPool
0% fee

in doubts of the quality...
*steal 30% of hash rate
*many people have problems with this pool
*seems to be the brother of Zpool and have a bad reputation
*mining profit spikes too high that it's unreal (this is because of the value of shit coin)
*Dev support not replying to technical questions. Afraid to reveal hidden secrets

the good thing is...
*you can mine lot of shit coins
*mines 2 or 3 coins at the same time in a algo
*0.004 payout on sunday (some people didn't get paid)

1 1080ti profit: TBD


Flypool (recommended by crairezx20)
1% fee

Pro
*Mine Zcash, the most profitable on equihash
*Part of Ethermine which they have a very good reputation
*1 of the lowest payout with 0.001 ZEC

Cons
*only Zcash. Sometimes other coins are more profitable.
*Lyra2Rev2 is the second porfitable algo and not available. So keep in mind what you want to mine



INTERFACE

Awesome Miner
the only cons are...
*need to pay for more features (reasonable in my point of view)
*Limited pools available for profit switching
*can't add mining software


Sniffdog
I need to test and might do it next week


OC/UC
For Nvidia is not difficult to do it with afterburner or GPU Tweak II. Lot of people fail to OC because of the power limit that is not enough, for this, need to use a power monitor.
Playing with OC/UC I could control the temperature and hash rat. Note: giving more clock to the limit, the hash rate drops
this is my results on equihash

BTG
GPU Clock 65 / Memory Clock 303
716~742 sol/s

Zcash
GPU Clock 65 / Memory Clock 303
730~740 sol/s

Zencash
GPU Clock 65 / Memory Clock 303
722~737 sol/s

*tested with a Platimax 1350w on a rig with 4 1080ti


PS: the objective is to get BTC at the end for cashout. I can update the status if everybody share

I don't think there can be full-fledged advice on this topic. Most learn from their mistakes and only then start to go into profit. You just need to analyze the market more.               

It's all about learning by doing and avoiding doing same mistake several times.
Knowing how indicators work, what candle and chart patterns are etc. is just theory.
But getting a feeling for the market and how certain coin charts behave is something you will only learn when you trade again and again.
The more and longer you do it, the more your experience will grow over time.
But it's also about patience and the will to go through tough times when you feel you're not progressing. Hang on and do not give up!
And please don't fall for all that shit sales pitch and signal group out there. All you need is for free on the internet! Youtube is your book where even don't have to read! Just watch. Then join active trading communities and share opinions and informations with others who are in the same boat with you. Then you're on the right path!

Hello,

I'm hoping to get 75 S9's in my garage. I'm planning all of this out and am trying to figure out how many amps I need to support that. Is it right I'd need almost 500 amps to my garage to support all 75 S9s?

I'm very confused on this math because I've seen many posts that say 400 amps support up to 100 S9s but that doesn't jive with what I'm calculating what I'd need.

Thank you!

There are a LOT of post explaining this, but one more time, in round numbers:

Frequency * power consumption / joules per GH = chip power consumption
chip power consumption / power supply efficiency = 12V power drain, shy a bit for fans, the controller, etc.
wattage / voltage = amps (remember Ohm's law???)
breakers should never be continuously loaded for more than 80% of their rated capacity
wire should always be rated at the breaker rating (or larger, but nobody commonly does that)

so:

13500 MH* 0.098 J/MH = 1323 watts (just like the Bitmain page says)
1323 watts / 0.93 efficiency = 1422 watts, call it 1450 with fans an controller for this exercise
1450 watts / 220 volts = 6.6 amps
20 amp breaker allows you to use 12 gauge wire, which is easier than 10 gauge if you opt for 30 amp breakers
20 amps * 0.80 = 16 amps allowable per breaker
Therefore:  You can put 2 miners on a 20 amp 220V breaker

(75) S9s would require (38) 20 amp 220V breakers.

A 200 amp breaker panel has a 200 amp master breaker at top.  80% rule applies to that too, so 160 amps total usable per panel.

160 amps / 6.6 amps (which is pushing it to the limit) = 24 miners per panel or (12) 20 amp circuits, but...

A typical 200 amp indoor main breaker panel has 30 spaces, 60 circuits, 15 spaces per side.  Each 220V breaker requires 2 spaces, so you can only get (7) 220V breakers in per side, but that would overload the panel since 7 per side = 14 breakers = 28 miners = 185 amps which is greater than the limit.

You can find 20 space, 40 circuit 200 amp panels that work out better:  20 spaces = 10 breakers = 5 per side.  10 breakers = 20 miners = 132 amps which is comfortably below the 160 amp limit.

Using those 20 space panels would mean you would need (4) such panels.  To power them, you would need 75 * 6.6 = 495 amps of continuous draw power spread between those panels.

That is excluding power for lights, fans, etc. (not to mention the rest of your house)

Then there is the minor problem of getting rid of 1450*75 = 108,750 watts of waste heat, but that is a different discussion.

Oh, and dealing with the noise.

It should be noted that the last word is "partially" a checksum... the way the seed is "broken up" is into 11bits chunks... 11 bits = 2048... hence 2048 words.

As per BIP39 (https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki#generating-the-mnemonic), you start with Entropy which is 128 to 256 bits... and divide that by 32 to get checksum length... in the case of the Ledger, they use 256 bits... so checksum length is only 8 bits... but the last word is 11 bits of info... so it's actually partially data/partially checksum.

This is why, even with just the last word missing there are still multiple "valid" combinations... as (for a 24 word mnemonic) the last word will have 3 bits at the beginning which are data... and generate up to 8 different values which will generate 8 different words.

In the UK house run 230v. the socket ring will start/end in the fuse box usually in a 32Amp breaker. (go check your fuse box; often the rings are labeled). So you can draw 32*230 = 7360W on the entire ring. The highest rated fuse you will find in an appliance plug (including your A3; and yes the Bitmain APW3++ is the easiest way to go). 13 *230 = 2990W, therefore the maximum total wattage you can have plugged into an individual socket is 2990W. I believe you need to not exceed 80% of maximum load (someone please correct if wrong) of this if you are running continuously (like a miner). 80% of 2990W is 2392W. So in theory each socket can draw a max of 2392W until you reach the total ring load of 5888 (80% of 7360W).

Typically a washer will be around 700W but may go higher for shorter periods of time. All appliances will have a sticker telling you the info.

The A3 is 1186W and a washer of 700W so these could both be on the same ring (probably best not to have them in the same socket), with quite a few other appliances.

Again, I am not an electrician so if anyone else here has and more informed information please chip in. If in doubt get it checked!!!! But one miner shouldn't cause you an issue. What country are you in?

14  Other / Meta / Educational Ban: grant TMan and Jet Cash temporary ban powers on: March 08, 2018, 02:38:57 AM
Proposal

Allow a few chosen members the power to do a 1 week ban on Newbie and Jr. Members whose posts are garbage.  Yes, someone will argue that all levels have garbage, but  start with the new ones first.

I believe that TMan and Jet Cash should have this power as they have shown themselves to be good judges based on their activity in the past. (yep, just my opinion)

When the ban occurs, the user should receive an email like this:

“Based on your recent posts, you have been banned for 1 week, please read the following topics and LEARN before posting:
Newbie read before posting: https://bitcointalk.org/index.php?topic=1689727.msg16958010#msg16958010

need to merit for bounty

i am not being merited yet...
hope so its important...
I don't think merit is the best way.

16  Other / Meta / Create a level above Legendary on: February 28, 2018, 05:25:04 PM
theymos,

Please create a level above Legendary.

My vote would be to call it Mythical.

Why:
-   Legendaries are bright, energetic, experienced (quirky, opinionated) people, if they don’t have something to work to, they will turn their energy to other distractions
-   Legendaries have a lot of experience, a new level will help pull that out.
-   Its human nature to compete
-   I have found people need to be motivated to perform best
-   Everyone needs a goal to work to
-   A lot of legendaries exist simply because of time momentum, this will bring out true leaders
-   Merited post of legendaries could be used to create a BOK (Book of Knowledge)
-   Their merited posts would serve as models to lower ranks

Requirements
-   Merit required 2500 total
-   No added activity requirements (then it’s all about quality, not quantity)
-   No automatic level up. Once hitting the required merit, it should be voted on by a panel created by Theymos
-   No ‘race to the top’.  No more than 10 merits allowed from one account to another per month
-   No merit awarded for work previous to February 1, 2018 would count in the 1500 new merits (legendaries already received 1000 merits for that work, the new rank would be forward looking)
-   Leveling up to Mythical is a privilege that you need to work to. Smerits are meant to be spent.   Encouraging ‘merit-worthy’ posts is part of the ‘job’ of a Mythical. As such, if a legendary has not awarded a minimum number of merits per month, the remaining amount should be deducted from accumulated Mythical merit. (Sort of like a signature campaign, you want Mythical, you work for it)
-   Minimum merits never drop below the 1000 historical merits awarded
-   If the average user (me) has to use a dictionary, no merits awarded for that post (nullius) (just kidding)

Logistics
-   Might need a second merit tracker for Legendary only: Mythical Merits
-   Would need a page to show the top 10 in the ‘race’ and links to their merited posts

Questions
-   What to do about negative trust, related or not. (my take is the panel would judge)
17  Other / Meta / Can a bad post recieve merit and then be deleted to hide it, and KEEP the merit? on: February 21, 2018, 05:59:30 AM
I just ran across this, is this a new way to hide abuse?

1) Create a post that says 'blah'
2) Have a friend (or alt) send it a lot of merit
3) Delete the post to hide the bad content
4) Keep the merit points

Edit:

I am NOT ADVOCATING this, I think I just saw someone with a deleted post that still had 18 merits attached to it.



18  Other / Meta / The funny side of 'Merit Talk' on: February 07, 2018, 03:02:57 AM
Some of these merit postings are bat-crap hilarious.

You have to love google translate.

These are clipped from actual postings in the Meta section, and they all made me laugh.

(If you recognize yourself, don't get mad!)

Please post your funniest findings:
_______________________________________________________________________________ ____
-I guees only theymos who knows the clear whole scope of merit. I do believed that merit given by him is quite creepy to all unanimous members.

-well, actually i am not good poster so this merit system will put me in problem anyway.

-I hope you can petrify me

-The forum becomes full with empty content posts. So i do believe in this new technic which represents a control system that fixes the upgrade criteria

-but must be qualified and really beguna for others. so I think this is very appropriate with the merit

-This concludes that the system is absolute and can not be jeopardized, to think that they've already made a defense mechanism to the system.

-Petulant, self-entitled brat.  You get an F in logic

-Overall I am also happy with the new merit system. As more and more people start to learn about the new rules, they will think twice before making useless posts.

-Although I agree that this prevents everyone of us from posting nonsense, I'm just not confident enough in my posts that they are merit-worthy.

-I don't have any merit to sell but I will lease my forum name for 10btc a month

-I think you cant sell your merit. Because for me merit can give you by the founder of the bitcoin.

-I guess if peopole start selling it they are going to get some bad trust from Lauda. So, it's highly unlikely.

-Yes, merit is not for sale because selling merits isn't prohibited or acquired. I think those bitcointalk users who sell bitcoin will be punished, I don't think so.

-weighing merit that is nearing the next rank as I live looking for merit to be able to ride a full member
19  Other / Meta / Merit has Opened my Eyes on: February 02, 2018, 04:33:46 AM
The new merit system has had some value.

I went back and looked at previous postings:
       -   25% of my posts are shitposts   (These can stop)
       -   30% of my posts are trying to be funny, but few ‘get me’  (Its in my DNA, can’t stop)
       -   The rest are asking for info, answering someone else’s request, or ‘suggesting’ improvements to a vendor for poor ordering system.

But the real benefit to me is learning just how valuable the signature campaigns are!

I have not been around too long, and didn’t pay any attention to signature campaigns.  I think I checked once and it seemed to be chump change ($.50 cents a post or something like that).

But when I look at the sigs of some hero/legendary posters:

Chipmixer: up to 50 posts/week at .00075btc (say BTC was 12k) - $450/week! https://bitcointalk.org/index.php?topic=1935179.0

Dock.io  $150/week https://bitcointalk.org/index.php?topic=2770108.0

Fortunejack, as much as $720/week.  https://bitcointalk.org/index.php?topic=1713944.0

I joined to learn more on Bitcoin and Altcoins, and improve my ability to mine, now I realize, there is more.

So.. it works! The merit system has opened my eyes to

       -   Some poor posting habits
       -   Other ways to make income in bitcoin
       -   The fact that I need to venture out from just the mining threads I normally travel to.
 
I wish I had learned these before the merit system though!

I feel this not a feel good shitpost for at least a couple of reasons:
-   Informing others about the value of Sig’s (am I the last to know?)
-   Adding a small voice of positive to the wail of negative (before complaining, review your posts)
20  Bitcoin / Mining support / New Avalon 741 dead fan on: December 10, 2017, 09:01:54 PM
New unit, hashed for 10 min, fan working, then silence.

I let it cool down, reflashed the PI, checked the fan plug (is ok)

Miner starts, blue light, auc3 green.
I set min fan % to 50, nothing

Has good hash rate, fan won't start, you can see the Fan % climb, but the rpm stays at zero and it does not move.
I will research how to test a 4 pin PWM fan

Any ideas?
