Mining Rig, Room, And Farm Cooling Ideas

Would a bitcoin mining rig cooled to absolute zero (−273.15°C.) use nearly no electricity to run? Not counting the energy required to get to that low temperature.

Question for you scientific types out there?

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.
Bear trap:
A manipulation of a stock or commodity by investors.
Bitcoin:
The very first, and the highest ever valued, mass-market open source and decentralized cryptocurrency and digital payment system that runs on a worldwide peer to peer network. It operates independently of any centralized authorities
Bitconnect:

He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.
Bull market:
A market that Cryptos are going up.
Consensus:
An agreement among blockchain participants on the validity of data. Consensus is reached when the majority of nodes on the network verify that the transaction is 100% valid.
Crypto bubble:
The instability of cryptocurrencies in terms of price value
Cryptocurrency:
A type of digital currency, secured by strong computer code (cryptography), that operates independently of any middlemen or central authoritie
Cryptography:
The art of converting sensitive data into a format unreadable for unauthorized users, which when decoded would result in a meaningful statement.
Cryptojacking:
The use of someone else’s device and profiting from its computational power to mine cryptocurrency without their knowledge and consent.
Crypto-Valhalla:
When HODLers(holders) eventually cash out they go to a place called crypto-Valhalla. The strong will be separated from the weak and the strong will then be given lambos.
DAO:
Decentralized Autonomous Organizations. It defines A blockchain technology inspired organization or corporation that exists and operates without human intervention.
Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:
Long red or green candles. This is a crypto signal that tells you that it is not favorable to trade at the moment. Found on candlestick charts.
Digital Signature:
An encrypted digital code attached to an electronic document to prove that the sender is who they say they are and confirm that a transaction is valid and should be accepted by the network.
Double Spending:
An attack on the blockchain where a malicious user manipulates the network by sending digital money to two different recipients at exactly the same time.
DYOR:

Faucet:
A website which gives away free cryptocurrencies.
Fiat money:
Fiat currency is legal tender whose value is backed by the government that issued it, such as the US dollar or UK pound.
Fork:
A split in the blockchain, resulting in two separate branches, an original and a new alternate version of the cryptocurrency. As a single blockchain forks into two, they will both run simultaneously on different parts of the network. For example, Bitcoin Cash is a Bitcoin fork.
FOMO:
Fear of missing out.
Frictionless:
A system is frictionless when there are zero transaction costs or trading retraints.
FUD:
Fear, Uncertainty and Doubt regarding the crypto market.
Gas:
A fee paid to run transactions, dapps and smart contracts on Ethereum.
Halving:
A 50% decrease in block reward after the mining of a pre-specified number of blocks. Every 4 years, the “reward” for successfully mining a block of bitcoin is reduced by half. This is referred to as “Halving”.
Hardware wallet:
Physical wallet devices that can securely store cryptocurrency maximally. Some examples are Ledger Nano S**,** Digital Bitbox and more**.**
Hash:
The process that takes input data of varying sizes, performs an operation on it and converts it into a fixed size output. It cannot be reversed.
Hashing:
The process by which you mine bitcoin or similar cryptocurrency, by trying to solve the mathematical problem within it, using cryptographic hash functions.

Pre mining:
The mining of a cryptocurrency by its developers before it is released to the public.
Proof of stake (POS):
A consensus distribution algorithm which essentially rewards you based upon the amount of the coin that you own. In other words, more investment in the coin will leads to more gain when you mine with this protocol In Proof of Stake, the resource held by the “miner” is their stake in the currency.
PROOF OF WORK (POW) :
The competition of computers competing to solve a tough crypto math problem. The first computer that does this is allowed to create new blocks and record information.” The miner is then usually rewarded via transaction fees.
Protocol:
A standardized set of rules for formatting and processing data.
Public key / private key:
A cryptographic code that allows a user to receive cryptocurrencies into an account. The public key is made available to everyone via a publicly accessible directory, and the private key remains confidential to its respective owner.

Experiences with Mining Hosting Services

I have been exploring using Blockware Solutions to do bitcoin mining hosting for a couple S17 + rigs and wanted to see if others have had experience with this company or using a host for mining in general. Any info with pros & cons is appreciated.
Current quote is for 6.3c electric costs that are locked into a 2 year contract. Includes the shelf space, maintenance, cooling, etc. The S17+ per unit are $2400.
Based on my research this would profit a mere $60 per month or put another way, an ROI of 6.5 years at current market rate! I know the price is set to fly over the next couple years but still...
Is anyone using this company or know of competitors for me to look into?

hey i have some questions about cryptocurrencys

so i am really new to all that. and my english isnt the best so bare with me and help me understand all that better
the thing i do not understand is: what does satoshi do with all his coins (better what could he do)
and why are there so many transactions (3,500 says google) per block why not just one per block?
and then WHEN will it happen that bitcoin mining just isnt profitable anymore because of the to high electricity costs.
so i am in a funny position where i dont have to pay for my energy bill but all i have, is a crappy internet connection and a ryzen 5 8 gb ram laptop, (i am currently typing this in shool)
could i start mining or would i just be crushed by someone with 8 RTX 2080 ti super in a cool rgb rig in his climate controlled closet?

3D Printed Housing for External Vive Wireless Card

Sorry I am not providing details as I want to get this info out quickly. I will respond with info if anyone shows interest, though I might be slow.
I'm not sure if anyone remembers the talk about extending the range of their Vive wireless setups. Basically, you can get a PCIe extender (built for bitcoin mining rigs I believe), and use USB 3 to move your Vive Wireless WiGig card 35 ft (CORRECTION: 20ft) to your computer. I have found that it works great for me.
But you end up with this exposed computer board just sitting there in your room with nothing to keep the board from sliding out of the extender socket and nothing to protect the board while also allowing cooling.
I took enough measurements off of the board to create a 3d model of it that captures the design information needed to create an enclosure.
I also created a 3d printable enclosure that is "good enough".
I haven't posted it because "an artist's work is never done", but if I don't post what I have, I might never post it.
So please let me know if anyone is interested in a model of the card and enclosure. Note that the enclosure is specific to the dimensions of the extender I bought, so minor tweaks might be required if you have a different extender.
Here is a picture of the final result (yes I used tape for my prototype that I never developed further)
I designed it to be modular (see the joiners I left open in the picture, in case a part of the print fails or needs fixing) and also it does not require supports. (Shakes fist at designs that require supports!)
https://imgur.com/a/op35gVL
(I would appreciate advice on how to get the image to show up in this post, I don't do this a lot)
Answers:
Here are the exact two products I bought from Amazon. No guarantees. At the time people were looking into extending the wire from the card to antenna, but my first try didn't work.
Beware, the part that you plug into your pci slot can, incredibly, be put in backwards and still fit. Also there is nothing keeping the extender in the slot.

In 2012 I Met a Possessed Couch

I’ve been losing sleep. I don’t think I’m particularly special in that regard, I think everyone has been losing sleep these days. A global pandemic tends to do that to people. Yet the thing that has been keeping me awake isn’t the virus. I’ve been losing sleep over an old couch I once crossed paths with.
It’s been eight years, I want to believe that I’ve put the past behind me, but being locked in a house for a couple of weeks has made it impossible to not dwell on the past. The memory of the couch started off as a fleeting thought over my morning coffee, but as days have turned into weeks that memory has grown into a distinct vision of madness. What I saw during those three drunken nights in December of 2012 has become an unavoidable part of reality. I can’t rest until I process it.
So since we have a nice little Internet campfire going here I figured I would tell you guys a story. Hopefully it will let me put this whole part of my past to rest and maybe it will take your mind off of what is happening outside. So kick back and let me tell you a tale of love and loss, of broken teenage hearts, of surviving in a crumbling world. Let me tell you a story about the couch that tried to seduce me.

I was nineteen, hung-over and heartbroken. I was also stuck in a foreign country. Well, to call Estonia a foreign country would be a bit of a long shot, I had lived there for a good five years of my life. It was in Estonia that I lived out most of my teenage years. This was where I had smoked my first cigarette, had my first drink, fell in love for the first time. I was dragged in when I was thirteen by my parents; they had business in Tallinn and wherever they went I went. At eighteen, when my parent’s contracts ran out, I was forced back home. Their business with Estonia was done. Mine was not. By nineteen I was back.
As soon as I got off the plane I turned my phone on and checked my messages. She didn’t write to me. My soul, positioned somewhere slightly above my abdomen, twitched in discomfort. It was a familiar twitch, I had felt it in the bus to the airport, I had felt it in the security check, I had felt it when I boarded the flight to Tallinn and as soon as I got off the plane the twitch was back with a vengeance. The discomfort I was feeling in my chest was a realization. It was the realization that I had emptied out most of my already slim bank account on a one-way ticket halfway across the continent to see my old high-school sweetheart who wasn’t interested in seeing me. It was the realization that as much as I consciously knew the trip was a bad idea, I couldn’t resist going. I dragged my feet towards the arrivals hall.
When it became obvious that Saale was dodging my messages I panicked. There was no place for me to crash, I had no money for a flight, hell, I had no money for food. As I boarded the plane to Estonia I sent off a panicked text message to my old band-mate: ‘Made horrible mistake. Landing in Tallinn in three hours. Can I crash at yours?’ Within two minutes there was a reply: ‘OK. Will come with Maarja. See you soon.’ Karl wasn’t very chatty, but he was always there when needed.
The two of them were waiting for me as soon as I walked out into the arrival hall. They barely changed. Karl was still a giant of man. His long hair had gotten longer and the beard he had rocked since seventeen had gotten thicker, the guy looked like Jesus on steroids if Jesus was really into heavy metal and wore glasses. Next to Karl stood Maarja, she wore a garish yellow coat. The pink streak in her hair she’d been so proud of back in middle school was pinker than ever.
“JAAMEEES! YOU’RE BACK!” Maarja yelled in her high-pitched faux-English accent before nearly tackling me to the ground. “It’s been too long honey! Too long!” She hadn’t changed a bit since I left the country. Maarja was still a pint-sized bolt of energy. The two of them made for an odd couple.
“Welcome back, Friend,” Karl said after Maarja was done squeezing me. He wasn’t one for physical contact, Karl settled on a simple pat on the shoulder that challenged my entire skeletal structure. The three of us made our way outside to catch a bus to the center. Even after living in Estonia for five years I still wasn’t used to the winters. As soon as we walked out into the sub-zero temperature I felt decidedly like a foreigner.
We caught up on the small things while we waited for the bus. Karl and Maarja had officially moved in together, the band that Karl and me started up in high-school had broken up, Maarja was in the process of getting a bachelors degree of psychology and Karl was really into some crypto-currency stuff that went completely over my head. I couldn’t get much out of me; the cold was taking a real toll on my system. Whenever I opened my mouth to talk about my miserable little life I simply ended up chattering my teeth. As soon as we got on the bus I threw myself at the nearest heating vent.
“So, James,” Maarja said as soon as we got on the bus, “You still talk to Saale?” When I turned away from the heater to face her she froze, “I mean, we don’t have to talk about, forget I asked.”
“Do I look that bad?”
While Maarja searched for a diplomatic answer Karl stepped in with his special brand of honesty, “You look very tired and unhappy.”
“Well, I am happy to see you guys and I am excited to be here, but, yeah,” I decided to get the conversation out of the way, “We tried two months of long-distance, but Skype only gets you so far. Broke up in late July. After we split we agreed to not talk for a couple of months, to give each other some time to clear the system and all that. Keeping radio silence was hard at first but after a couple of weeks I started to get used to it. I was learning to live without her. Things were starting to straighten up, I even took a stab at dating but when the holidays rolled around the loneliness came back. On Christmas I figured I’d throw Saale a holiday message. She wrote back. We started chatting on a daily basis.”
The bus bounced through my old neighborhood. Memories of my drunken youth jumped at me from every corner, most of those memories involved Saale. “Last night we got pretty drunk,” I continued, “Things got flirty. We started talking about what we would do if we weren’t half a continent away from each other. She mentioned her parents were out of town until the end of January on some sort of an anniversary trip. I offered to fly in. She told me I should. Now I’m here.”
“She changed her mind?” Karl asked.
“She didn’t think I was serious about flying over. Didn’t exactly check with her before I bought the ticket. She flipped out when I got it, told me to get a refund and then hung up on me when I insisted on meeting up. She hasn’t answered any of my messages since.” A part of me felt good to get the story out of my system but saying it out loud just added to the absurdity. I could have not bought the ticket, I could have gotten a refund, I could have not gotten on that plane. Everything could have been avoided, but nineteen year old me leaped at the opportunity for a grand romantic gesture like a hungry animal.
“Very strange,” Karl finally said after considering my story. He shot a look over to Maarja, as if she was the ambassador to all women-kind, “Very strange, right?”
Maarja shrugged.
Maarja’s house was the crown jewel of my high-school social life. It was a three-apartment unit that was built at some point before the world wars. This place was old, as you would walk around the little apartment it would creak, but it made for a perfect party place. Maarja had inherited the apartment from her grandma at sixteen; the Estonians saw child rearing as a fairly independent process. If she couldn’t survive on her own at sixteen she probably couldn’t make it at thirty, a bit of responsibility would prepare her for the frigid world outside. Maarja used her newly found independence to throw the biggest house parties that the neighborhood had ever seen.
Maarja’s place was perfect for booze filled gatherings. It was spacious enough to hold any drinking game we could dream up, there was a nice terrace for smoking and the neighbors were either deaf, completely apathetic about teenage drinking or both. As soon as the front door opened I was assaulted by memories.
Visions of drunken nights on the floor of the living room, of hung-over mornings of the kitchen; the old apartment breathed with the past. For a split second a wave of gratitude for a youth well spent washed over me, but then I remembered that each of those fond memories had an element I wanted to block out. Most of the fun I had in the apartment had been with Saale by my side.
Maarja and Karl still slept on an old mattress on the floor, the walls were still covered with cut outs of boy-bands that Maarja had stuck to the wall in her tweens. The only thing that changed about their bedroom was the addition of a massive computer rig on the table. There were strange ventilators and cooling tubes and blinking lights, the machine looked like something straight out of a sci-fi flick.
“That’s my mining rig,” Karl said proudly. I nodded as if I understood what he was talking about.
“Where are the rats?” I asked, noticing the empty cage on Maarja’s wardrobe. Back in the day Maarja had two rats, Fritz and The Duchess. She would keep them in the cage most of the time, but whenever the night reached a certain point of drunkenness Maarja would sneak over to her bedroom and come out with the two animals. If you saw Maarja with two rats running up and down her body you knew the night was really going to become a rager.
“The Duchess died last week,” Maarja said with a glint of sorrow, “Fritz wasn’t taking it well. Think the little guy was depressed being in the cage all alone, so I’m letting him roam around the house for the time being. Hopefully a bit of freedom will cheer him up.” As if he had heard his name, Fritz peeked out from behind the wardrobe. The albino rat raised his snout in the air, sniffed for a bit and then lumbered off to the living room. The years had taken their toll on Fritz, he no longer moved with the youthful energy I was used to, but the one part of him that I remembered had not changed. Fritz still had balls that were disproportionately giant to his body. As he moved away from us he dragged them behind him with Sisyphean effort.
“So, which hostel are you crashing at?” Maarja asked. A lump manifested in my throat. I looked around the cramped apartment. Outside of the mattress there was nowhere for me to sleep. I didn’t have any money for a hostel. “Ah, I’m just kidding. You’re crashing here. We owe you anyway,” Maarja said with good cheer.
“For what?” I asked, relieved that I wasn’t homeless.
“Financing the booze and cigarettes back in the day, might have ended up a nun if it weren’t for you,” she said with a grin. It was true, throughout high school I had been the main financier of our misadventures, my parents had foreign money and that money went pretty far by Estonian standards. More importantly though; when everyone was sixteen I looked twelve. According to the law of teen streets, the late bloomer provides the dough for those who can buy stuff without ID.
“You’ll sleep on the couch, we just haven’t had the time to get it out of the garage. How about you and Karl drag it in while I make some tea?”
Even though it was a bright winter day outside the garage was in near darkness. The only thing that illuminated the cramped musty room was a single ray of light shining in through a cracked skylight. The garage was covered in flimsy shelves that buckled beneath the weight of greasy machine parts. In the center of the garage lay a couch shaped object covered with a large, stained cloth. Karl grabbed ahold the cloth and was about to pull it away, but a thought struck him.
“James, if I tell you something will you not tell Maarja?” He asked, letting the cloth drop back down to the floor. He looked straight at me; his small eyes were probing me for trustworthiness.
“Well, depends on what it is,” I said, “Don’t need help burying a body, right?”
“No,” Karl’s intensity broke into a smile, “It is nothing illegal. Just a secret.” He strode towards one of the rickety shelves and plunged his hand deep into its depths. After a moment of rustling he pulled out a small box. He opened it. Even though the garage was dark, and even though the diamond was tiny, you could see a little glimmer. Karl’s eyes shone twice as bright.
“Wow man,” I said, realizing how quickly the world was moving on, “Congratulations!” Maarja and Karl would get married and I would be at their wedding alone. As I stood in that garage the thought that I would always be alone gushed dread through my veins. We used to joke about how Saale and me would get hitched before the two of them did. Those jokes felt cruel now. Maarja and Karl would get married and one day Saale would get married too. She would get married to someone who wasn’t me. “I’m really happy for you.”
“I want to ask her father soon. He does not like me much, but I think I can show him that I can provide for his daughter. This Bitcoin thing will be big soon James, in a couple of years me and Maarja will be rich.” Karl put the box back into its hiding place. “Promise not to tell her, yes?”
“Promise,” I said with as much candor as I could muster, but my mind was elsewhere. My mind was floating disembodied in a bright church, watching my would-be-wife get married to someone else.
“James,” Karl’s paw on my shoulder brought me back into reality, “You will be okay. I know you are worried about Saale, but you still have us. We will drink this away.” He smiled. I tried to smile back. “Let’s get this couch, shall we?”
He pulled away at the cloth that covered the couch. Enough dust flew off into the air to send us both into a coughing fit. The room danced with dirty particles. Yet from behind the veil of powder I could see it. I could see the couch.
The thing was ancient, a couch straight out of the early days of the Soviet Union. Its flowery upholstery was covered in stains that just screamed history. It was as if the piece of furniture had been used for barricades in the defense of Stalingrad and lived to talk about it. Filth filled its rumpled cloth, it stood on firm wooden legs that seemed to have survived multiple generations of being clawed at, it was as if the thing was simply biding its time until its true masters came back to retrieve it. The couch was old, but somehow in that dark garage, in that gust of earthly smoke, there was something alluring about it. It looked ratty but comfortable, even inviting. For a split second I was sure that the couch had winked at me with its cushioning. Then the dust settled and it was just a piece of furniture.
Karl grabbed one side of the couch, I grabbed the other and we started to haul the thing towards the living room. We had left the garage, but there was still tension in the air. I was still thinking about Saale getting married to someone who wasn’t me. It was still as if Karl and me were meant to have a serious discussion. Neither of us were comfortable.
“I lost my virginity on this couch,” I shared, hoping to relax the situation.
Karl grinned, accepting the levity, “Gross.”
We dragged the couch to the living room and then joined Maarja in the kitchen. Back in the day her kitchen table was the go-to place to gather before drinking and after drinking. We would sit around and shoot the shit and wait for someone to drop off the booze for the evening or the hung-over pizza for the morning. Yet as we sat there, trying to make small talk, one of the chairs was empty and it made all the difference. I couldn’t focus on anything that was being said around me, all I could think about was how Saale used to sit next to me. All I could think about were her long legs on my lap, her long fiery hair, her laughter.
“How about we sweeten the evening with a bit of moonshine?” Maarja asked, as she fished a clear bottle out of the kitchen counter, “Karl and me are going to lunch with my parents tomorrow though, so no hangovers.”
Karl cheered on the promise of alcohol, but not even drink could lift my spirits. My eyes shifted from Saale’s empty seat to the couch. All I wanted to do was lie down and fall asleep for a thousand years. “Guys, I appreciate the hospitality but I’m really tired. How about we drink tomorrow?” I said. Karl and Maarja looked concerned, this was the first time they had ever seen me refuse booze.
“Are you sure you’re okay honey? We can talk about it if you want to,” Maarja suggested. I insisted I was fine; I just needed to get some rest. That didn’t convince her, but she yielded, “Well, we’ll be in my room if you need us.” Her and Karl shuffled off to her bedroom. I laid down on the couch.
From the other room I could hear them talk. Maarja talked in concerned whispers whilst Karl spoke at full volume, it didn’t make much of a difference, even after five years of being in the country I still couldn’t understand Estonian. I could hear my name being mentioned though. They were concerned about the emotional wreck that was crashing on their couch. I dragged my friends into my mess. It was all so humiliating; I was far from home, broke and broken. I wanted to die.
‘Easy there Tiger, don’t think like that,’ a faint voice emerged from the back of my head, ‘Things might not seem great right now, but look on the bright side, at least you’re on a comfortable couch.’ The voice was right; the couch was indeed comfortable. ‘All you need is a bit of a distraction to forget about your broken heart. Some booze, some dope, maybe a bit of love and you’ll be good as new.’ It was as if the suave voice turned a switch in my mind. Suddenly the tightness in my chest eased, a burst of joy started to bubble in my abdomen. My fingers started to trace the sides of the upholstery. The voice giggled, ‘That’s the spirit Tiger, just relax, you’re fine as long as you’re here with me.’ The universe felt lighter, my feelings of dread faded away and were replaced with an electric anticipation. I needed a drink to celebrate.
I opened the door to Maarja’s bedroom. She was lounging on the mattress reading a psych textbook. Karl was watching bar graphs on the computer. “Hey guys,” I peeked in, “I feel a bit better now, how about those drinks?” They both grinned. We drank.
In the moment I didn’t give much thought to the voice in my head, my internal monologue was turned up a notch since the break-up anyway. I was used to hearing thoughts that I consciously didn’t want to consider; the silky voice that was telling me that things would be okay was a welcome distraction. I sunk into the couch and I let the night carry me away. ‘See Tiger? Isn’t it nice to be here? Isn’t life just swell on this little old couch?’ it would say. I nodded along. We drank more.
All thoughts of avoiding hangovers were let go; the liquor poured freely. At some point Maarja emerged out of her room with Fritz on her shoulder. We celebrated the tradition of our youth but the rat was sluggish, far too old to crawl around on her body. After a couple of minutes Maarja gave up on playing with the rat. She put him on the ground. Fritz simply walked around the room dragging his testacles behind him like a ball and chain. We drank more.
Karl lumbered up to his feet and went to fetch his guitar. Maarja was out having a cigarette. I was far too comfortable on the couch. Having a moment to myself I watched the rat. Fritz had spent the past couple of minutes roaming the living room and sniffing at my backpack. Yet suddenly something caught his attention, he sniffed at the air, his whiskers bouncing in curiosity. Then he looked towards the couch. The old rat sprung to his hind legs and turned towards me. It was as if his beady eyes were locked to the piece of furniture. ‘Oh Tiger, don’t think about the stupid rat. Look, here comes Karl, let’s stop thinking about stupid things and listen to him play.’
Oh and how he could play. To say that Karl lacked warmth would be an understatement, communicating with the guy often felt like having a conversation with a pile of awkwardly stacked encyclopedias, but as soon as he would bring out the guitar he would ooze personality. Somehow, with those hulking fingers of his, Karl had managed to make the strings sing the gentlest of tones. Maarja and me sang along out of key as the night went on. ‘Just like the good old days, Tiger, you’re here and you’re happy. Focus on the positives, focus on the present,’ the voice told me. I followed the advice, until I couldn’t.
It was as if a spell had been broken. As soon as I heard those opening chords, as soon as I realized what Karl was playing my stomach sank. It was that Rolling Stones song. Saale and me had danced to it once upon a time. Memories of our first night together came rushing into my mind. The Saale shaped hole in my heart throbbed with pain. I got up to splash some water on my face. Karl shifted his performance into a serenade for Maarja.
The tiles in the bathroom were freezing but I was willing to withstand the pain if it meant I could get further away from the song. I stood there, willing to wait it out, but the memories just kept on floating back. I was standing in the same bathroom I stood in the night that I met Saale. I could see traces of a sixteen-year old in my face. The music kept on building. Saale’s lily perfume filled my nostrils. I could remember the fullness of her lips before our first kiss. The images were cascading on top of each other, ripping away at my sanity, ready to plunge me into a panic attack. But then they stopped. The music stopped.
I peeked out of the door. Karl had chucked his guitar over to the side. His serenade had given way to a heavy make out session. Him and Maarja were all over each other. “Guys, I’m going to go out for a cigarette,” I announced.
The two of them looked up at me dazed and drunk. “Take the keys honey, I think we’re going to bed.”
I hoped that the dial tone would block out Maarja’s moans but it didn’t. Not only did I have to listen to a loving couple have sex, I also had to listen to world’s quietest dial tone as I was reminded that Saale did not want to talk to me. I stood out there in the freezing cold smoking one cigarette after another. It was just me, the starless sky and Maarja’s moans. Karl lasted for a quarter a pack before their bedroom quieted down. I tried calling Saale one more time and then went back inside.
By the time I stumbled to the couch I could already hear snoring coming from the bedroom. But there was another sound in the apartment, something much quieter, something I almost didn’t notice. Scratching.
Luckily I managed to prop myself up against the couch before I sat on him. As I tried to regain my balance I realized just how drunk I was. Fritz was on the couch, furiously scratching into its upholstery. He looked up at the drunken figure hovering over him for a split second and then went back to work. Those little claws scratched with the ferocity of a pup. It was as if Fritz was two years younger.
I picked him up by his scruff and tried taking him off the couch. When I lifted him off the ground the rat seemed confused for just a split second before-
‘Aiiieee’ Fritz screamed the world’s tiniest scream and then bit me in the finger. He dropped to the ground and ran beneath a nearby wardrobe. He hid beneath it and watched me.
I was too drunk and tired to care. I laid down on the couch and exhaled. ‘Welcome back Tiger, you look tired. Let me keep you company. Yes, life is hard, but if you really appreciate the moment it can be pretty enjoyable. Lie down here, let me keep you hold you. Let’s get to know each other better.’
I could smell floral perfume. I closed my eyes and drifted off to a deep sleep.

AMD Threadripper 3970x - My adventure so far (Will edit as I go)

I own a gaming community called Unknown Skies gaming (For a little Context) and we are planning a server upgrade. Currently we have a Dell R620 with Dual E5-2690 V2's Running @ 3.3Ghz, has 196GB Ram. The game we host on this rig is called Empyrion Galactic Survival.
The reason for the upgrade is currently the server just isnt high end enough to continue supporting our target playerbase of 100 players, and Performance has dipped due to the game being alpha and the devs are not doing much to improve server side efficiency. Back in 7.0 we could host 150 players on this machine, now it struggles with 60... Yeah big change in 2 years.
After a lot of research... I can clearly see Intel Xeon Gold 6154 CPUs (2 of them) do not outperform even the R9 3950x according to passmark. The price of these used intel servers is stunningly high on the used market... Dual 18 Core XG 6154 Processors with 128gb ram (Dell R740 I think, feel free to correct me) cost right around 10,000$ USD Used give or take 1000$ or so... And get stomped on by an 800$ Single Socket CPU... Thats new and has a warranty... I get that it doesnt support as much memory... But Dang...
So I looked into threadripper... HOLY SHAT!! The 3970x hits 60k+ in passmark... And the ENTIRE system with a custom cooling loop is less than 6 Grand? Thats nuts to me! Amazing Deal! Im sad all my servers and rigs are intel hahahahaha.
What we need, What im aiming for, and my thought process - Feel free to leave thoughts and suggestions..
AMD Threadripper 3970x (Because High Per thread throughput matters due to shit code, and more players on a playfield means more cpu usage on that thread, Lots of threads matter as every playfield opens a new PlayfieldServer.exe and is its own instance so the more spread out players are, the more cores you need to spread out workload. 32 cores 64 threads... NICE)
Corsair Vengeance LPX 256 GB (8 x 32 GB) DDR4-3200 Memory (Each player uses around 1-3gb ram, 2 on average, goal was 100 Players)
ASRock TRX40 TAICHI ATX sTRX4 Motherboard (Thought this was a solid selection given the options I saw)
EVGA 1000 W 80+ Gold Certified Semi-modular ATX Power Supply SHOULD be sufficient with a closed loop water cooler, all SSD's and not requiring a gaming GPU (Plan on a 1050ti / 1050 at most)
Case im using is a modified 4U rackmount case with 3x 120mm fans going in the front, radiator behind those. Could NOT find one that I didnt have to modify. Went with El-cheapo option cause imma be drilling it and modding it internally - Rosewill Server Chassis Server Case Rackmount Case for Bitcoin Mining 4U off ebay I think it will work, and if not I have a file server that would LOVE the home LMAO. So it was well worth the Chance.
Water cooling Solution I settled on was a Thermaltake Floe TR4 Edition. I thought about using a Custom Cooling loop, but by the time I priced everything out the way I would do it... It came out to like 500$ ish LMAO. The above cooler From what I can tell should be sufficient, and should fit in the case i chose. Tight fit, but should fit.
Im excitedly looking forward to the build :) Anyone have any experience with any of this and care to chime in?

Antminer T19 May Not Affect Bitcoin Hash Rate but Keeps Bitmain Ahead

The Antminer T19 by Bitmain may not have a big impact on the Bitcoin network, and it comes out amid the firm’s internal and post-halving uncertainty.
Earlier this week, Chinese mining-hardware juggernaut Bitmain unveiled its new product, an application-specific integrated circuit called Antminer T19. The Bitcoin (BTC) mining unit is the latest to join the new generation of ASICs — state-of-the-art devices designed to mitigate increased mining difficulty by maximizing the terahashes-per-second output.
The Antminer T19 announcement comes amid the post-halving uncertainty and follows the company’s recent problems with its S17 units. So, can this new machine help Bitmain to reinforce its somewhat hobbled position in the mining sector?
T19: The cheaper S19
According to the official announcement, the Antminer T19 features a mining speed of 84 TH/s and a power efficiency of 37.5 joules per TH. The chips used in the new device are the same as those equipped in the Antminer S19 and S19 Pro, though it uses the new APW12 version of the power supply system that allows the device to start up faster.
Bitmain usually markets its Antminer T devices as the most cost-effective ones, while the S-series models are presented as the top of the line in terms of productivity for their respective generation, Johnson Xu — the head of research and analytics at Tokensight — explained to Cointelegraph. According to data from F2Pool, one of the largest Bitcoin mining pools, Antminer T19s can generate $3.97 of profit each day, while Antminer S19s and Antminer S19 Pros can earn $4.86 and $6.24, respectively, based on an average electricity cost of $0.05 per kilowatt-hour.
Antminer T19s, which consume 3,150 watts, are being sold for $1,749 per unit. Antminer S19 machines, on the other hand, cost $1,785 and consume 3,250 watts. Antminer S19 Pro devices, the most efficient of three, are considerably more expensive and go for $2,407. The reason Bitmain is producing another model for the 19 series is due to what is known as "binning" chips, Marc Fresa — the founder of mining firmware company Asic.to — explained to Cointelegraph:
“When chips are designed they are meant to achieve specific performance levels. Chips that fail to hit their target numbers, such as not achieving the power standards or their thermal output, are often ‘Binned.’ Instead of throwing these chips in the garbage bin, these chips are resold into another unit with a lower performance level. In the case of Bitmain S19 chips that don’t make the cutoff are then sold in the T19 for cheaper since they do not perform as well as the counterpart.” The rollout of a new model “has nothing to do with the fact that machines are not selling well,” Fresa went on to argue, citing the post-halving uncertainty: “The biggest reason machines probably are not selling as well as manufacturers would like is because we are on a bit of a tipping point; The halving just happened, the price can go anyway and the difficulty is continuing to drop.” Product diversification is a common strategy for mining hardware producers, given that customers tend to aim for different specifications, Kristy-Leigh Minehan, a consultant and the former chief technology officer of Genesis Mining, told Cointelegraph:
“ASICs don’t really allow for one model as consumers expect a certain performance level from a machine, and unfortunately silicon is not a perfect process — many times you’ll get a batch that performs better or worse than projected due to the nature of the materials. Thus, you end up with 5–10 different model numbers.” It is not yet clear how efficient the 19-series devices are because they have not shipped at scale, as Leo Zhang, the founder of Anicca Research, summed up in a conversation with Cointelegraph. The first batch of S19 units reportedly shipped out around May 12, while the T19 shipments will start between June 21 and June 30. It is also worth noting that, at this time, Bitmain only sells up to two T19 miners per user “to prevent hoarding.”
Hardware problems and competitors
The latest generation of Bitmain ASICs follows the release of the S17 units, which have received mostly mixed-to-negative reviews in the community. In early May, Arseniy Grusha, the co-founder of crypto consulting and mining firm Wattum, created a Telegram group for consumers unsatisfied with the S17 units they purchased from Bitmain. As Grusha explained to Cointelegraph at the time, out of the 420 Antminer S17+ devices his company bought, roughly 30%, or around 130 machines, turned out to be bad units.
Similarly, Samson Mow, the chief strategy officer of blockchain infrastructure firm Blockstream, tweeted earlier in April that Bitmain customers have a 20%–30% failure rate with Antminer S17 and T17 units. “The Antminer 17 series is generally considered not great,” added Zhang. He additionally noted that Chinese hardware company and competitor Micro BT has been stepping on Bitmain’s toes lately with the release of its highly productive M30 series, which prompted Bitmain to step up its efforts:
“Whatsminer gained significant market share in the past two years. According to their COO, in 2019 MicroBT sold ~35% of the network hashrate. Needless to say Bitmain is under a lot of pressure both from competitors and internal politics. They have been working on the 19 series for a while. The specs and price look very attractive.” Minehan confirmed that MicroBT has been gaining traction on the market, but refrained from saying that Bitmain is losing market share as a result: “I think MicroBT is offering option and bringing in new participants, and giving farms a choice. Most farms will have both Bitmain and MicroBT side by side, rather than exclusively host one manufacturer.”
“I would say that MicroBT has taken up the existing market share that Canaan has left,” she added, referring to another China-based mining player that recently reported a net loss of $5.6 million in the first quarter of 2020 and cut the price of its mining hardware by up to 50%.
Indeed, some large-scale operations seem to be diversifying their equipment with MicroBT units. Earlier this week, United States mining firm Marathon Patent Group announced that it had installed 700 Whatsminer M30S+ ASICs produced by MicroBT. However, it is also reportedly waiting for a delivery of 1,160 Antminer S19 Pro units produced by Bitmain, meaning that it also remains loyal to the current market leader.
Will the hash rate be affected?
Bitcoin’s hash rate plummeted 30% soon after the halving occurred as much of the older generation equipment became unprofitable due to the increased mining difficulty. That spurred miners to reshuffle, upgrading their current rigs and selling older machines to places where electricity is cheaper — meaning that some of them had to temporarily unplug.
The situation has stabilized since, with the hash rate fluctuating around 100 TH/s for the past few days. Some experts attribute that to the start of the wet season in Sichuan, a southwest Chinese province where miners take advantage of low hydroelectricity prices between May and October.
The arrival of the new generation of ASICs is expected to drive the hash rate even higher, at least once upgraded units become widely available. So, will the newly revealed T19 model make any impact on the state of the network?
Experts agree that it won’t affect the hash rate to a major degree, as it’s a lower output model compared with the S19 series and MicroBT’s M30 series. Minehan said she doesn’t expect the T19 model “to have a huge impact that’s an immediate cause of concern,” as “most likely this is a run of <3500 units of a particular bin quality.” Similarly, Mark D’Aria, the CEO of crypto consulting firm Bitpro, told Cointelegraph:
“There isn’t a strong reason to expect the new model to significantly affect the hashrate. It might be a slightly more compelling option to a miner with extraordinarily inexpensive electricity, but otherwise they likely would have just purchased an S19 instead.” Bitmain continues to hold leadership despite internal struggle
At the end of the day, manufacturers are always in an arms race, and mining machines are simply commodity products, Zhang argued in a conversation with Cointelegraph:
“Besides price, performance, and failure rate, there are not many factors that can help a manufacturer differentiate from the others. The relentless competition led to where we are today.” According to Zhang, as the iteration rate naturally slows down in the future, there will be more facilities using “creative thermal design such as immersion cooling,” hoping to maximize the mining efficiency beyond just using most powerful machines.
As for now, Bitmain remains the leader of the mining race, despite having to deal with the largely defunct 17 series and an intensifying power struggle between its two co-founders, Jihan Wu and Micree Zhan, which recently resulted in reports of a street brawl.
“Due to its recent internal issues, Bitmain is facing challenges to keep its strong position in the future thus they started to look at other things to expand its industry influences,” Xu told Cointelegraph. He added that Bitmain “will still dominate the industry position in the near future due to its network effect,” although its current problems might allow competitors such as MicroBT to catch up.
Earlier this week, the power struggle inside Bitmain intensified even further as Micree Zhan, an ousted executive of the mining titan, reportedly led a group of private guards to overtake the company’s office in Beijing.
Meanwhile, Bitmain continues to expand its operations. Last week, the mining company revealed it was extending its “Ant Training Academy” certification program to North America, with the first courses set to launch in the fall. As such, Bitmain seems to be doubling down on the U.S.-based mining sector, which has been growing recently. The Beijing-based company already operates what it classifies as “the world’s largest” mining facility in Rockdale, Texas, which has a planned capacity of 50 megawatts that can later be expanded to 300 megawatts.

Building an Ethereum Mining Rig (13 GPU) - 4th part

Third update to the guide "Building a Mining Rig for Ethereum". The absolute first guide to building a RX Vega 64 8gb 13 GPU Mining Rig.
Reading this guide to building a 13 GPU Ethereum mining rig requires adequate knowledge of building and running an Ethereum Mining Rig. We therefore recommend a previous view of our Guide to build a Mining Rig and related updates.

Let's immediately list the hardware used:

- Asus Mining Master X370 mainboard
- Core i5 Coffee Lake CPU
- 480 or 500GB SSD
- 32Gb Ram
- 13 GPU RX Vega 64 8Gb
- 3 x 1000W power supplies
- 1 1200W power supply
- 8Gb USB stick

In this guide we will obviously not explain how to mount the hardware of a Rig. The only notes we wish to underline are the following:

- the 1200W power supply must be the primary one on which to connect 4 GPUs and the video output for the monitor

- all the risers, as well as obviously the GPUs, must be powered through the 8-pole connections of the power supplies. We strongly advise against the use of 6-pole ports. Therefore, have the appropriate number of cables available for all connections. Risers can also be powered in pairs.

- the model of the video card used is the Asus Rog Strixx Gaming RX Vega 64 8Gb


The operating system is Windows 10 updated to the latest version available. The tool for creating installation media is available at the following link https://www.microsoft.com/it-it/software-download/windows10 to be able to use the USB key as a launcher for installing Windows 10 .

With the Asus Mining Master, the GPU risers can be connected directly to the motherboard via the USB cable, thus making one of the small components of the riser kits unusable.

After making all the connections on the motherboard, check that all GPUs are highlighted in green when the PC starts up. If not, move the USB cable on the motherboard one position. It may take at least 2 or 3 attempts.

Ethereum mining with 13 GPUs
Having solved this possible small inconvenience, let's proceed with the installation of the AMD Adrenaline 2020 drivers, always updated to the latest version, relating to the RX Vega Series.

If you want to proceed with more caution, the advice is to disconnect all the GPUs (remembering the locations of the USB cables) except one before installing the drivers.

The mining will be carried out on the Ethermine pool, our favorite, using the Claymore 15 software.


Once the download is complete, you will have to unzip the folder on the desktop and open the start.bat file contained in the Claymore folder using Notepad. The procedure is the usual one: delete the content and copy-paste the following command string:

start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker"
EthDcrMiner64.exe

Where EthDcrMiner64.exe is the executable, -epool indicates the pool to mine and its port, -ewal is the wallet address and -epsw is the password that we leave blank (X).

In place of "your wallet address" you will have to put your Ethererum wallet and instead of worker you will enter an identification number in case you plan to build more RIGs (such as RIG1, RIG2, etc ...).

At the following link, many other useful commands for your Rig:
https://github.com/Claymore-Dual/Claymore-Dual-Miner

Try to run mining and check that the system is stable.

In the Payouts section, after a few minutes of mining, you can decide the minimum amount of Ether to be sent to your wallet by simply entering the IP address of the RIG.

We performed the mining directly on the Ethereum address of the Exodus wallet. Coinbase is not supported.

Overclocking with OverdriveNTool
Let's proceed now with the download of OverdrivenTool at the following link: https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/


For those unfamiliar with it, we recommend reading our software guide.

For those who do not intend to experiment or do not completely trust their software experience, at the following link you can view the settings on the parameters of the GPUs and the RAM of the GPUs - and other small tricks - to obtain the best possible performance without forcing the cards too much. video.

On our Youtube channel (subscribe numerous !!!) you will now be able to see the video relating to the start of mining and the one concerning the stabilization phase.

To better cool the Rig we have also installed fans for the extraction of heat as caution is never too much. Moreover, there is also an aesthetic gain.

Conclusions on the guide to build a 13 gpu ethereum mining rig.
Finally, we conclude this guide by reporting what everyone was waiting for (we do not say how long we had to wait before obtaining this result) the video link complhttps: //www.youtube.com/watch? V = k53XZn3zc9I & t = 61seto del Rig e del Mining .

We remain available for any advice, both on pools, on yield and on consumption.

Feel free to contact us in case you run into any problems where our guide to Building a 13 GPU Ethereum Mining Rig has not been completely helpful.

See you soon.
