ELI5: Difference between CPU and GPU silicon

This may be a stupid question, but is there any fundamental difference between CPUs and GPUs at the silicon level?
I know that GPUs are typically used for outputting an image, while CPUs are more important for logic processing and the like. However, there are also some tasks like [email protected] and bitcoin mining, which are little more than math with a backstory running on GPUs more effectively than CPUs. These tasks can also run on a CPU. Further, Linus managed to play Crysis on a Threadripper without any GPU. Also, ia AMD putting more and more cores onto their CPUs, like they are trying to make a GPU (which have many cores). This leads to the question of if there is any fundamental difference between a GPU and a CPU. What will happen if someone was to slap a GPU into a CPU socket, and vise versa (assuming fitting and other logistics were taken care of)?

Alienware Alpha R1 is 2020

Alienware Alpha R1 in 2020*

Mistyped the title...
This is going to be a simple guide to help any R1 owner upgrade and optimize their Alpha.

Upgradable Parts

(In order of importance)
Storage Unit:
HDD OUT
SSD IN
This is by far the easiest upgrade to make and the most effective.
https://www.newegg.com/p/pl?N=100011693%20600038463
Any of those will work, just needs to be 2.5 Inch SATA.
How to Replace Video

WIFI Card:
This is like a 5-15$ upgrade. Go find any Intel 7265ngw off eBay and replace it with your current WIFI card. If you don’t want to buy used then here.
How to Replace Video

RAM:
Ram prices have tanked because of bitcoin mining, so this has become quite a cheap upgrade as well. I’d recommend 16GB just because why not, but if your tight on cash 8GB is fine.
https://www.newegg.com/p/pl?N=100007609%20601190332%20601342186%20600000401&Order=BESTMATCH
How to Replace Video

CPU:
This required the most research. I’d recommend you look through this first. The wattage of the processor slot only ranges from 35w-50w according to a developer of the Alpha (Source). The socket type is LGA 1150.
If you’re going cheap, the i5-4590t (35w) and i5-4690s (65w) are both great options.
i5-4590t
i5-4690s
The i5-4690t (45w) is also great but is hard to find from a trustworthy source for a reasonable price.
If your willing to spend $100+ then easily the i7-4790t (45w). That is probably the best processor to put in the Alpha. All 45w will be used giving you 3.9 GHz Turbo. The T series apparently runs the best on the R1 according to This Reddit post.
How to Replace Video

GPU:
Coming Soon!

Maxed out Alpha R1 specs: i7-4790t, 1TB Samsung SSD, 16GB DDR3, Nvidia Geforce GTX 860m.
(Upgrading to anything better then that is pointless)

I have Insomnia so I summoned The Sandman to help me sleep.

NoSleep. Ironically, I am posting this to NoSleep. You are here to read stories so scary that they will keep you up all night, I am here because I can’t fucking sleep. I haven’t slept in 3 days, and I can’t even remember the last time I got real sleep. The kind where you go to sleep and stay asleep. The kind where you naturally drift off to a relaxing sleep and not your body forcibly shutting itself down against its own will. So I am sorry if I ramble some, but I can’t help but laugh at the irony of this being on no sleep. Is that funny to you too, or just to me because I am too tired to be rational?
I have real insomnia. The kind where people think you are insane, and to be honest, they aren’t wrong. I have had it since I was in college, but it has only gotten worse and worse. I can't even remember the last time I slept. Wait? I told you that already.
I’ve been to a sleep specialist. I’ve been on every sleeping pill you can think of. Melatonin, no caffeine, no naps, Ambien, Sonata, Lunesta, silenor, antidepressants, Seroquel, Ativan, benzos, you name it, I have taken more than they recommended. Still no relief or sleep.
I know, you are not reading this to read the ramblings of a madman who hasn’t slept in days. You are here because you want a scary story. I’ve got one for you. I think it is real. To be honest, when you haven’t had a real night's sleep in months, dreams and reality start to become one big blur.
The story starts about 6 months ago, maybe? It was still winter and the virus was not a big deal yet. I remember that much for sure.
I had been up for days when a commercial came on for an over the phone psychic reading. If a doctor couldn’t help, maybe a spiritual advisor could. No, I didn’t need a psychic, what I needed was a hypnotist. You have seen them before, they can just snap their fingers and you fall asleep instantly! This is the answer to all of my prayers.
It was a scam. They had me lay down and close my eyes, then they softly started talking while I tuned out. When I woke up, she said when I go to sleep at night to relax and listen to a youtube channel that softly plays music and tells you to relax. It didn’t work at all except that every time I listen to soft background music I get the strong urge to make a grilled cheese sandwich, which is weird because I had not had one since I was maybe 9. I think she just hypnotized me to crave grilled cheese. She probably invests in the Big Cheese Industry and makes money by making people crave grilled cheese. What a waste of money.
So much for that idea. The next night I still couldn’t sleep. I decided to watch my feel-good movie: Back to the Future. During the movie, Marty goes back in time to 1955 and there is a part where a song comes on, you hear the unmistakable BUM BUM BUM BUM BUM BUM BUM BUM BUM BUM BUM BUM BUMMMMMMM! MR. SANDMAN! BRING ME A DREAM! (That song will be stuck in your head for the rest of the day. I’m not sorry.)
When I heard the song, I started to boil over in rage. Maybe it was from the lack of sleep, or maybe I am just insane, but I picked up the remote and threw it into the LED screen breaking the tv. I screamed, “THAT IS THE MOTHER FUCKER WHO HAS CURSED ME! THE FUCKING SANDMAN! I AM GOING TO FIND HIM AND KILL HIM!”
This went on for longer than I am willing to admit, but you get the point. The Sandman was my enemy. The one who is supposed to deliver us into sleep every night had decided to stop visiting me. What had I ever done to him to make him skip me every night not allowing me to sleep? The Sandman was to blame.
The Sandman was going to have to answer for these wrongs. I was determined to find a way to confront him and give him a piece of my mind. I just had to figure out how the hell you could find or trap it. At this point, I don't care if The Sandman is God himself, I was going to find him..
I thought about it for a while and decided based on movies and books, the way to call a god to you is to summon it. Sounds simple enough, Let’s do it.
Another long story short, putting candles in a circle and yelling I SUMMON YOU SANDMAN! Doesn’t work.
Again, I was back on the internet looking for someone to help me. After talking to someone I was given the email of an African Witch Doctor named Mrs. Fatima. I emailed her and she agreed to help me if I send her bitcoin. She even offered to come out for more money, but screw that, I can do it myself. Why the hell does everything have to be so difficult? Can’t people just take a credit card like the rest of the world? Always extra steps for some weird-ass digital currency crap.
Screw it, I am willing to try anything at this point. I sent her the bitcoin. Whatever the hell that is. It is expensive, I can tell you that much.
After she got the money, she replied to my email with detailed instructions and a warning. She could help me summon The Sandman, but advised against it. Summoning a dead person is dangerous, summoning a demon is disastrous, summing a God is deadly. I thought about it for less than a moment and decided to do it. What is the worst that can happen? I die and am in an endless uninterrupted sleep for eternity? Sounds like heaven to me.
Under her instructions, I waited until 2 am the following night. You can do it anytime, but the barrier between the spirit realm and the mortal world is the thinnest in the early morning hours when people are sleeping. She advised to go somewhere secluded like in the middle of the woods since it would be desolated and more likely to work. I am doing it in my bedroom, it gets the same amount of girls in it as a desolated forest. Lucky for me, I also need the blood of a virgin, so I got that covered too! Just joking, I don’t need blood.
The first thing I needed to do was draw a large circle in chalk. The circle had to be complete and above all else, not broken. The circle is the doorway between realms, if it was not complete it would not work. It also acts as an invisible wall to keep the spirit contained once you summon it. Keep the circle complete at all times. I drew a circle on my hardwood floor. Easy.
The next step was to light 5 red candles drawing a pentagram star. They have to be red because the devil is red and we are practicing devil magic, that’s my explanation, not hers.
Inside the circle, I was to fill it with sand. If you are summoning The Sandman, you need sand?
That was all I needed. Some chalk, candles, a secluded spot, and sand. I was closer than I thought earlier.
Next, the hard part, summoning a god.
The first step is to clear your mind and meditate. Most people have a hard time with this, but I have been meditating for years. They said it would help me sleep, it doesn’t. Don’t waste your time.
The next step is to concentrate on the circle, opening the pathway in your mind. Like imagining it disappearing or opening it like a door?
When your mind is clear, envision the one you are summoning. Do I just imagine what I think he looks like in my head? It’ll have to work.
When you feel the energy start to peak, only then can you summon the spirit into the realm. Call out to the spirit you desire and demand it’s presence. Do not ask. Demand it. This is your world and you must stay in control at all times. If you give up control, the spirit will be able to take control and possibly hurt or kill you.
If you do everything right, you will have summoned the spirit.
Let’s do this. I have a bone to pick with that asshole Sandman.
The circle is drawn, the candles are lit, and sand is in the circle. I turned off the lights for good measure, it wasn’t in the instructions, but it makes for a better dramatic effect.
I closed my eyes and cleared my mind. I imagined the circle in my mind as an empty white space, a void, a door, then I imagined a portal like in the video game with a blue glowing loop.
Next, I imagined The Sandman. Was he a human figure who carried sand, or a God made of sand? I kept trying back and forth, and everything in between before I finally settled on a spirit outlined in the sand.
I held my concentration on The Sandman and the opening of the portal. It felt like nothing was happening when suddenly everything changed. My eyes were shut but I could feel the energy start to build in the room. It felt like a strong storm was blowing on the outside of the house. I couldn’t physically feel the force, but I could feel the pressure growing and growing. Finally, I felt the energy reach its crescendo like something was trying to push itself through the circle into my room.
It’s time to open the gate.
“I OPEN THE PATHWAY AND DEMAND YOUR PRESENCE SANDMAN! THE DOOR IS OPEN AND I ORDER YOU TO APPEAR BEFORE ME!
I felt resistance trying to pull energy back from the door, not wanting to obey.
“SANDMAN! APPEAR BEFORE ME NOW!”
The energy in the room seemed to explode out of the circle. I opened my eyes to see the sand turning in a tornado inside the circle high above my head. I gasped in shock, wondering if I was dreaming. This couldn’t be real. Suddenly the tornado dissolved and the sand formed into a figure with red eyes staring down at me.
“WHAT MORTAL DARES TO SUMMON ME!” He roared. “WHO HAS MADE SUCH THE MISTAKE TO SUMMON A GOD!”
I may have made a mistake. The thing is, spirits and especially Gods, do not like it when mortals summon them. They have to come if you summon them, and that pisses them off. They are over there doing ghost and god stuff and get interrupted by people who can’t even walk through a wall. So if you do ever try this, just expect the ghost or demon or god to be in a pissy mood when they come. It is understandable when you think about it.
I looked up at the god, not backing down, and responded “I did.”
Sand swirled around The Sandman as he looked at me in disbelief.
“You are The Sandman, right?” I yelled at him. “You are the god of sleep, the god of dreams, right?”
“I am,” it growled.
“Then why the fuck can I not sleep?” I said. “It has been years and I am stuck awake for days at a time. Why have you done this to me?”
A deep laugh came from the circle. “You think I care about you, mortal? Do you think I waste my time on someone as insignificant as you or your kind? I am a god. A GOD! I don’t have time to waste being here talking to you. Release me!”
“I am not going to release you until you give me what I want.”
The sand settled down and it was quiet. I waited for it to respond.
“You want something from a God? What do I get out of the deal? What do you have that I could possibly want?”
“Give you something?” I asked. “You are the asshole who won’t let me sleep.”
“I am feeling generous. We can make a deal,” it said. “I will give you the ability to sleep anytime you want”
“What is the catch?”
“Ahhh! The catch. Smarter than you look.” He said. “I am the God of Sleep and Dreams. You can sleep, but I will control your dreams.”
”Can’t you do that anyway?” You are the God of Dreams”
“Do we have a deal or no? Answer me before I change my mind.”
Damn it. I know he is playing me as a fool. Fuck it, I’ll solve my sleep problem now and worry about the catch later.
“We have a deal, Sandman.”
“A deal it is” he laughed. “Anytime you wish to sleep just say Mr. Sandman, Give me a dream.’ And you will be asleep in less than a minute.”
“You gotta be kidding me.”
“My game. My rules.” He said. “Now release me.”
“You are released.”
“See you in your dreams!”
The energy that had filled the room evaporated into thin air, the sand fell back into the circle, the candles went dark, and The Sandman was gone.
Was that real or am I hallucinating again? And damn! What even happened there? I was ready to cuss him out and he somehow took control of the encounter. Shit! Mrs. Fatima warned me it could be deadly if he took control. Then again, he made a deal and I can finally sleep.
What is done is done. I blew out the candles and decided to put our deal to the test. He will allow me to sleep anytime I want, real sleep, he will just be controlling my dreams. I’ve had nightmares, what happens in the dream world is all a dream. Nothing can hurt me there. Right?
It was 4:15 am. I turned off the lights, turned the fan on high, and put on some calming music and prepared to lay in bed awake for hours on end. I said the magic words As soon as I closed my eyes, I was out like a rock.
The dream started. I was back five minutes earlier saying “What happened in the dream world is all a dream. Nothing can hurt me there, right?” There was an echo repeating the same phrase back to me. That isn’t a good start.
I laid down in bed, just like before and closed my eyes trying to sleep but this time no sleep came, like always. I sat there for hours trying to sleep. I meditated, listened to calm music making me crave grilled cheese, and tried to will myself to sleep. My dream self was exhausted and on the verge of tears from being unable to sleep.
The Sandman’s idea of a joke is to give me insomnia in my dreams so I couldn’t escape it. Funny joke, but as long as I wake up refreshed I don’t care.
I looked at the clock and it was 7:45 and the sun was up or would be if I didn’t have the windows blacked out. Too exhausted to get up I laid in bed and prayed for sleep.
A moment later, the red candles flickered to life in a star pattern, the room went cold, then the sand started to swirl up into the air. The Sandman appeared in the circle.
My body stiffened, I couldn’t move a muscle, not even to close my eyes. Is this what sleep paralysis feels like? I thought back to my email with Mrs. Fatima and remembered as long as the circle was complete he would be stuck inside.
“That is only true when you’re awake. You’re in my world now,” he laughed as he floated across the circle to my bedside. “You brought me to your world, now I have you in mine. A deal is a deal.”
Ah shit. I knew taking his deal was a bad idea. Never negotiate with a god. You will never come out ahead. I tried to answer him but I was still paralyzed.
“Do you know the legend of The Sandman? The original story? The real story?” He stood over me.
Everyone knows the legend. He comes at night, sprinkles sand in your eyes so you will sleep well and have good dreams. You wake up with sand in your eyelashes.
“Wrong!” He yelled. “That is a story told much later after I left the mortal world to stop people from fearing me. You are about to find out the real legend of The Sandman.
I laid in bed unable to move, my eyes held open by some imaginary force, staring at him in fear.
He held out his hand in front of my face and blew. I felt the wind on my face followed by the sand. The awful awful sand. Unable to close my eyes the sand blanketed my eyes. I could feel every grain of sand stick to my eyes.
Finally, I had control of my eyes again and started to blink uncontrollably. Each blink the sand grinded deeper and deeper into my eyeballs and eye socket. Each blink felt like shards of glass cutting my eyes. My eyes became watery and started to tear up but it wasn’t tears but blood leaking down my face. The pain engulfed my face but I couldn’t move, only involuntary blinking trying to clear the sand from my eyes. Each blink the sand cut farther and farther into my eyes. The pain became excruciating like someone had stuck a red hot fire poker in each eye. I wanted to scream out but nothing else worked on my body. Then the pain disappeared.
I assumed I had blacked out or went unconscious but that doesn’t happen in dreams and I wasn’t that lucky. Instead, I felt a weird sensation on my eyeballs then the feeling of water being poured into my eye. When it stopped, my vision started to appear again, blurry at first but clearing. I could see a sandy palm and fingers like I was being carried in The Sandman’s hand.
“The legend of The Sandman isn’t that he comes to put sand in your eyes to help you sleep, he comes to put sand in your eyes to steal eyeballs of kids who stay up too late.” He said. “I’m making an exception for you.”
He opened his palm and I could see my lifeless body, still in bed, not moving, the face covered in blood with empty holes as eye sockets. I am seeing myself from my own eyeballs. What the fuck, even for a dream this is fucked up. Luckily the pain had stopped, for now.
“Do you know what happens next in the legend? Do you know what I do with the eyeballs I steal” He asked like I could to respond. I didn’t know the answer but I knew I was about to find out.
“Right you are. Close your eyes, It’’s a surprise.” He laughed. “Get it? You can’t! You have no eyelids. Hahaha”
Excuse me for not thinking the joke is funny, being the butt of the joke.
“He pointed my eyes toward the moon and asked, “Do you like The Dark Side of the Moon?”
What the hell does the Pink Floyd album have to do with anything? Who doesn’t like it?
“Great. Let’s take a trip there. You’re dreaming so we can be there in, what would you say, a blink of an eye?”
Fucking funny. A moment later, we were on the dark side of the moon. It looked like the moon, but dark. He walked into a crater and I started to hear cries. Not like human cries, more like an animal cry. Not just one animal but a bunch. The cries got louder and louder. Even in a dream, I knew something bad was about to happen.
We finally arrived at what I would call a nest. Not your typical earth nest, but an enclosure that held a bunch of giant ugly bird-like featherless babies. Not dinosaur big, but big enough. Each bird-like creature was lifting its beak up in the air crying for its parents to bring it back food. What the fuck kind of food was available on the moon or in space is beyond my understanding, but that’s exactly what my eyes were seeing.
“After I steal the eyeballs, I bring them back here and feed them to the birds. In your world, you may throw bread out to the birds for a treat. In my world, I feed them your eyes.”
Fuck. Can I wake up now? I really don’t feel like being eaten by a giant alien baby bird thing.
“The legend says I fed them to my children, but that is the part they got wrong.” He said. “Sweet dreams, prince.”
He tossed my eyes into the air into the waiting mouth of one of these creatures. I saw it’s beak close as my eyeballs exploded into a gooey mess.
The dream ended and I woke up in a panic. I tried to open my eyes but they were sealed shut. I lifted my hands, happy I could move again, and felt my eyelids crusted over with sand. I cleared them the best I could but needed a warm compress to clean all the salt out. When I finally opened my eyes, they hurt. Everything had happened in the dream, but somehow my eyes felt sore.
I thought back to what I said and heard in my dream, “It is just a dream, nothing can hurt me there.” It is true, I wasn’t really hurt, but I’ve never woken up feeling pain I got from a dream. What is going on?
Still, If I dreamed, that means I slept! A nightmare isn’t so bad if I get real sleep. The dream felt like it lasted hours, a few more nights of this and I will have a somewhat normal sleep schedule and feel rested. I looked at the clock to see it was 4:30. I slept 12 hours and 15 minutes. Amazing!
I opened the door to my room and walked into the kitchen and it was still dark. That can’t be right. It should be 4:30 pm, the middle of the afternoon. Did I sleep for 24 hours straight? I looked at my phone and saw the date. My heart dropped. I had only slept for 15 minutes. It is like dreams take place in another dimension where time doesn’t exist. The Sandman was able to torture me for hours in dream time while allowing me to sleep for a few minutes. I cried. Seriously, I cried like a baby.
He held up his end of the bargain, I can fall asleep any time I want to, except now I am afraid to go to sleep. Everytime I fall asleep, he takes me away to his realm and gives me nightmare after nightmare. Every dream is one where he does something horrible to me and my dream self feels every bit of excruciating pain. And he never allows me to sleep more than an hour at the most.
I eventually accepted my fate. He is going to torture me, but it is all a dream. I will wake up feeling mostly normal. Then things changed. It is like he knew I had stopped fighting, so he found a new way to hurt me. Instead of hurting me in my dreams, he started to make me watch him hurt people I loved in their dreams. I didn’t think it was real until I heard from my sister about how my niece has been having terrible nightmares and refusing to go to sleep. When she described her dreams, I already knew, because I was there too.
That has been my life for the past however many months. Instead of trying to take medicine or listen to music or having The Sandman put me to sleep, I try to use my insomnia to stay awake for as long as my body will withstand it. I drink coffee and energy drinks, I take adderall, but eventually sleep always comes, even if for short periods. No matter how hard you fight it, your body will always sleep, and the Sandman will be there waiting on me.

Anything in my current, fairly old (but water-cooled!), PC worth using in a new one?

I started building computers around the year 2000 and have never really done a complete build from scratch (for myself) after my first. I'd upgrade a part here and there, and over time everything has been replaced multiple times. However, I'm thinking, due to an upgrade hiatus (it took me a LONG time to "beat" Skyrim :-P), I'm at the end of the road. I'm close to the conclusion that, for the second time in my life, it makes sense for a fresh new build. I figure I'd run this past y'all first.
My next computer I'll use for both fun and work. On the fun side, it would ideally play modern games (Particularly, I'm eying Elder Scrolls VI and Baldurs Gate III) on decent settings on my 34" widescreen monitor. Work-wise, it needs to be able to run multiple docker containers and let me do other things (take notes in notion, google docs, etc.) while on a CPU-crushing video call. The budget is $1,500.
Here is my current setup and thoughts on each component:
Photos: https://imgur.com/a/xyM07dx

Things that may be useful:
Operating System: Windows 10 Professional (from upgrading from Windows 7... the DVD is hopefully somewhere)
PSU: Corsair TX850W - It has been trusty for the last eight years, but may not have the needed connectors for today's stuff.
Hard Drive: Crucial MX100 512 GB SATA SSD - 2.5-Inch, No performance complaints (specs claim 6.0 Gb/s), although I'm running out of storage space.
Optical Drive: Pioneer DVD-RW - Do people still put these in new computers? I also have an external USB DVD drive I could use in a pinch.
Case: Chieftec Dragon Mid Tower - this old case is steel and heavy as shit, which is actually nice as my dogs and toddlers are unlikely to knock it over inadvertently. It has a window which I like, although cable management is a massive pain in the ass. I'm not too fond of the door that covers the buttons and optical drive and lost it long ago.
Cooling: Custom water cooling setup - I water-cooled in 2002, overclocking my Athlon XP 1700+ from 1.4Ghz to 2.5. It was awesome. The radiator and T-valve are the original gangsters. I'm on my fifth pump, with my last three being the Swiftech MCP655-B, which I like. The current water block is some D-Tek for the old CPU socket. The radiator is an old Chevy Impala radiator (I think) that this guy I met on a 3DMark (now Futuremark) forum (jb2cool?) custom modified and made a shroud that houses two 120mm fans. I had to drill the shit out of my case to mount this thing in there. I'm very nostalgic about this setup, but it would also be a huge pain to fit into a new case.
Monitor: LG 34UM67-P 34 - 34" IPS widescreen; 5ms 2560 x 1080 60hz; is 60hz too slow these days?
Keyboard and mouse: Logitech Chordless Wave - USB dongle; wrists feel ok, no complaints

Things that probably will not be useful:
Motherboard: Gigabyte P45T-ES3G - I'm pretty sure I won't be reusing this. I also bought it to replace a more bad-ass motherboard that died when my previous power supply died and took it out with it. I do like how it had dual bios, though.
CPU: Intel Core 2 Quad Q6600 - Been impressed with this CPU lasting as long as it has. I wet sanded it down to a mirror finish ready to overclock the shit out of it, but then never got to it as life got in the way.
Memory: 4x4GB PC3-12800 DDR3 - G.Skill Ripjaws; ancient technology. Note: I want more than 16GB ram in my next build.
GPU: Asus Geforce GTX 460 - My previous GTX 460 died at the height of bitcoin, and any modern GPU was stupidly expensive. Replacing mine was only $30 on eBay, so that's the route I went.

tl;dr: are any of the above bolded components still worthwhile in a modern PC build?

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.

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?

The Sandman

NoSleep. Ironically, I am posting this to NoSleep. You are here to read stories so scary that they will keep you up all night, I am here because I can’t go to sleep. I haven’t slept in 3 days, and I can’t even remember the last time I got real sleep. The kind where you go to sleep and stay asleep. The kind where you naturally drift off to a relaxing sleep and not your body forcibly shutting itself down against its own will. So I am sorry if I ramble some, but I can’t help but laugh at the irony of this being on no sleep. Is that funny to you too, or just to me because I am too tired to be rational?
Every teenager thinks they have insomnia because they stayed up too long playing video games 2 nights in a row and fell asleep in class, then they sleep for 15 hours straight on the weekend. I was like that once. Life must be tough with that sort of insomnia.
I have real insomnia. The kind where people think you are insane, and to be honest, they aren’t wrong. I have had it since I was in college, but it has only gotten worse and worse. I can't even remember the last time I slept. Wait? I told you that already.
I’ve been to a sleep specialist. I’ve been on every sleeping pill you can think of. Melatonin, no caffeine, no naps, Ambien, Sonata, Lunesta, silenor, antidepressants, Seroquel, Ativan, benzos, you name it, I have taken more than they recommended. Still no relief or sleep.
I know, you are not reading this to read the ramblings of a madman who hasn’t slept in days. You are here because you want a scary story. I’ve got one for you. I think it is real. To be honest, when you haven’t had a real night's sleep in months, dreams and reality start to become one big blur. The truth is, when you are as desperate for sleep as I am, you will do almost anything to get even 1 night of real sleep, no matter how crazy it is.
The story starts about 6 months ago, maybe? It was still winter and the virus was not a big deal yet. I remember that much for sure.
At this time, my insomnia was at the worst it had been in a few years. I remember I had been up for 4 days straight. When you hit this point, you become jittery. You know when someone has had too much caffeine and they sort of shake uncontrollably. Eventually, lack of sleep does the same thing, my whole body feels like it is trembling, my teeth feel like they are chattering even though they are resting as normal, my hands can’t even hold my phone still.
Then there is your mind. You get Brain Fog. At first, it feels like you have been driving on the interstate for 10 hours and can't see or think straight, then you get a second burst of energy and feel great. Most people crash at this point. If you stay up, things that don’t make sense start to make sense. Last is paranoia and anxiety. Every shadow has something lurking in it, ready to jump out and take you. TV or Radio starts to talk to you. You go on Reddit but every story is the same, like god playing a trick on you. You get anxious, praying for sleep, knowing the anxiety is keeping you up even longer. You start to ramble like I am doing again right now.
Okay. I am gathering myself now.
I had been up for days when a commercial came on for an over the phone psychic reading. If a doctor couldn’t help, maybe a spiritual advisor could. No, I didn’t need a psychic, what I needed was a hypnotist. You have seen them before, they can just snap their fingers and you fall asleep instantly! This is the answer to all of my prayers.
It was a scam. They had me lay down and close my eyes, then they softly started talking while I tuned out. When I woke up, she said when I go to sleep at night to relax and listen to a youtube channel that softly plays music and tells you to relax. It didn’t work at all except that every time I listen to soft background music I get the strong urge to make a grilled cheese sandwich, which is weird because I had not had one since I was maybe 9. I think she just hypnotized me to crave grilled cheese. She probably invests in the Big Cheese Industry and makes money by making people crave grilled cheese. What a waste of money.
So much for that idea. The next night I still couldn’t sleep. I decided to watch my feel-good movie: Back to the Future. During the movie, Marty goes back in time to 1955 and there is a part where a song comes on, you hear the unmistakable BUM BUM BUM BUM BUM BUM BUM BUM BUM BUM BUM BUM BUMMMMMMM! MR. SANDMAN! BRING ME A DREAM! (That song will be stuck in your head for the rest of the day. I’m not sorry.)
When I heard the song, I started to boil over in rage. Maybe it was from the lack of sleep, or maybe I am just insane, but I picked up the remote and threw it into the LED screen breaking the tv. I screamed, “THAT IS THE MOTHER FUCKER WHO HAS CURSED ME! THE FUCKING SANDMAN! I AM GOING TO FIND HIM AND KILL HIM!”
This went on for longer than I am willing to admit, but you get the point. The Sandman was my enemy. The one who is supposed to deliver us into sleep every night had decided to stop visiting me. What had I ever done to him to make him skip me every night not allowing me to sleep? The Sandman was to blame.
The Sandman was going to have to answer for these wrongs. I was determined to find a way to confront him and give him a piece of my mind. I just had to figure out how the hell you could find or trap it. At this point, I don't care if The Sandman is God himself, I was going to find him..
I thought about it for a while and decided based on movies and books, the way to call a god to you is to summon it. Sounds simple enough, Let’s do it.
Another long story short, putting candles in a circle and yelling I SUMMON YOU SANDMAN! Doesn’t work.
Again, I was back on the internet looking for someone to help me. After talking to someone I was given the email of an African Witch Doctor named Mrs. Fatima. I emailed her and she agreed to help me if I send her bitcoin. She even offered to come out for more money, but screw that, I can do it myself. Why the hell does everything have to be so difficult? Can’t people just take a credit card like the rest of the world? Always extra steps for some weird-ass digital currency crap.
Screw it, I am willing to try anything at this point. I sent her the bitcoin. Whatever the hell that is. It is expensive, I can tell you that much.
After she got the money, she replied to my email with detailed instructions and a warning. She could help me summon The Sandman, but advised against it. Summoning a dead person is dangerous, summoning a demon is disastrous, summing a God is deadly. I thought about it for less than a moment and decided to do it. What is the worst that can happen? I die and am in an endless uninterrupted sleep for eternity? Sounds like heaven to me.
Under her instructions, I waited until 2 am the following night. You can do it anytime, but the barrier between the spirit realm and the mortal world is the thinnest in the early morning hours when people are sleeping. She advised to go somewhere secluded like in the middle of the woods since it would be desolated and more likely to work. I am doing it in my bedroom, it gets the same amount of girls in it as a desolated forest. Lucky for me, I also need the blood of a virgin, so I got that covered too! Just joking, I don’t need blood.
The first thing I needed to do was draw a large circle in chalk. The circle had to be complete and above all else, not broken. The circle is the doorway between realms, if it was not complete it would not work. It also acts as an invisible wall to keep the spirit contained once you summon it. Keep the circle complete at all times. I drew a circle on my hardwood floor. Easy.
The next step was to light 5 red candles drawing a pentagram star. They have to be red because the devil is red and we are practicing devil magic, that’s my explanation, not hers.
Inside the circle, I was to fill it with sand. If you are summoning The Sandman, you need sand?
That was all I needed. Some chalk, candles, a secluded spot, and sand. I was closer than I thought earlier.
Next, the hard part, summoning a god.
The first step is to clear your mind and meditate. Most people have a hard time with this, but I have been meditating for years. They said it would help me sleep, it doesn’t. Don’t waste your time.
The next step is to concentrate on the circle, opening the pathway in your mind. Like imagining it disappearing or opening it like a door?
When your mind is clear, envision the one you are summoning. Do I just imagine what I think he looks like in my head? It’ll have to work.
When you feel the energy start to peak, only then can you summon the spirit into the realm. Call out to the spirit you desire and demand it’s presence. Do not ask. Demand it. This is your world and you must stay in control at all times. If you give up control, the spirit will be able to take control and possibly hurt or kill you.
If you do everything right, you will have summoned the spirit.
Let’s do this. I have a bone to pick with that asshole Sandman.
The circle is drawn, the candles are lit, and sand is in the circle. I turned off the lights for good measure, it wasn’t in the instructions, but it makes for a better dramatic effect.
I closed my eyes and cleared my mind. I imagined the circle in my mind as an empty white space, a void, a door, then I imagined a portal like in the video game with a blue glowing loop.
Next, I imagined The Sandman. Was he a human figure who carried sand, or a God made of sand? I kept trying back and forth, and everything in between before I finally settled on a spirit outlined in the sand.
I held my concentration on The Sandman and the opening of the portal. It felt like nothing was happening when suddenly everything changed. My eyes were shut but I could feel the energy start to build in the room. It felt like a strong storm was blowing on the outside of the house. I couldn’t physically feel the force, but I could feel the pressure growing and growing. Finally, I felt the energy reach its crescendo like something was trying to push itself through the circle into my room.
It’s time to open the gate.
“I OPEN THE PATHWAY AND DEMAND YOUR PRESENCE SANDMAN! THE DOOR IS OPEN AND I ORDER YOU TO APPEAR BEFORE ME!
I felt resistance trying to pull energy back from the door, not wanting to obey.
“SANDMAN! APPEAR BEFORE ME NOW!”
The energy in the room seemed to explode out of the circle. I opened my eyes to see the sand turning in a tornado inside the circle high above my head. I gasped in shock, wondering if I was dreaming. This couldn’t be real. Suddenly the tornado dissolved and the sand formed into a figure with red eyes staring down at me.
“WHAT MORTAL DARES TO SUMMON ME!” He roared. “WHO HAS MADE SUCH THE MISTAKE TO SUMMON A GOD!”
I may have made a mistake. The thing is, spirits and especially Gods, do not like it when mortals summon them. They have to come if you summon them, and that pisses them off. They are over there doing ghost and god stuff and get interrupted by people who can’t even walk through a wall. So if you do ever try this, just expect the ghost or demon or god to be in a pissy mood when they come. It is understandable when you think about it.
I looked up at the god, not backing down, and responded “I did.”
Sand swirled around The Sandman as he looked at me in disbelief.
“You are The Sandman, right?” I yelled at him. “You are the god of sleep, the god of dreams, right?”
“I am,” it growled.
“Then why the fuck can I not sleep?” I said. “It has been years and I am stuck awake for days at a time. Why have you done this to me?”
A deep laugh came from the circle. “You think I care about you, mortal? Do you think I waste my time on someone as insignificant as you or your kind? I am a god. A GOD! I don’t have time to waste being here talking to you. Release me!”
“I am not going to release you until you give me what I want.”
The sand settled down and it was quiet. I waited for it to respond.
“You want something from a God? What do I get out of the deal? What do you have that I could possibly want?”
“Give you something?” I asked. “You are the asshole who won’t let me sleep.”
“I am feeling generous. We can make a deal,” it said. “I will give you the ability to sleep anytime you want”
“What is the catch?”
“Ahhh! The catch. Smarter than you look.” He said. “I am the God of Sleep and Dreams. You can sleep, but I will control your dreams.”
”Can’t you do that anyway?” You are the God of Dreams”
“Do we have a deal or no? Answer me before I change my mind.”
Damn it. I know he is playing me as a fool. Fuck it, I’ll solve my sleep problem now and worry about the catch later.
“We have a deal, Sandman.”
“A deal it is” he laughed. “Anytime you wish to sleep just say Mr. Sandman, Give me a dream.’ And you will be asleep in less than a minute.”
“You gotta be kidding me.”
“My game. My rules.” He said. “Now release me.”
“You are released.”
“See you in your dreams!”
The energy that had filled the room evaporated into thin air, the sand fell back into the circle, the candles went dark, and The Sandman was gone.
Was that real or am I hallucinating again? And damn! What even happened there? I was ready to cuss him out and he somehow took control of the encounter. Shit! Mrs. Fatima warned me it could be deadly if he took control. Then again, he made a deal and I can finally sleep.
What is done is done. I blew out the candles and decided to put our deal to the test. He will allow me to sleep anytime I want, real sleep, he will just be controlling my dreams. I’ve had nightmares, what happens in the dream world is all a dream. Nothing can hurt me there. Right?
It was 4:15 am. I turned off the lights, turned the fan on high, and put on some calming music and prepared to lay in bed awake for hours on end. I said the magic words As soon as I closed my eyes, I was out like a rock.
The dream started. I was back five minutes earlier saying “What happened in the dream world is all a dream. Nothing can hurt me there, right?” There was an echo repeating the same phrase back to me. That isn’t a good start.
I laid down in bed, just like before and closed my eyes trying to sleep but this time no sleep came, like always. I sat there for hours trying to sleep. I meditated, listened to calm music making me crave grilled cheese, and tried to will myself to sleep. My dream self was exhausted and on the verge of tears from being unable to sleep.
The Sandman’s idea of a joke is to give me insomnia in my dreams so I couldn’t escape it. Funny joke, but as long as I wake up refreshed I don’t care.
I looked at the clock and it was 7:45 and the sun was up or would be if I didn’t have the windows blacked out. Too exhausted to get up I laid in bed and prayed for sleep.
A moment later, the red candles flickered to life in a star pattern, the room went cold, then the sand started to swirl up into the air. The Sandman appeared in the circle.
My body stiffened, I couldn’t move a muscle, not even to close my eyes. Is this what sleep paralysis feels like? I thought back to my email with Mrs. Fatima and remembered as long as the circle was complete he would be stuck inside.
“That is only true when you’re awake. You’re in my world now,” he laughed as he floated across the circle to my bedside. “You brought me to your world, now I have you in mine. A deal is a deal.”
Ah shit. I knew taking his deal was a bad idea. Never negotiate with a god. You will never come out ahead. I tried to answer him but I was still paralyzed.
“Do you know the legend of The Sandman? The original story? The real story?” He stood over me.
Everyone knows the legend. He comes at night, sprinkles sand in your eyes so you will sleep well and have good dreams. You wake up with sand in your eyelashes.
“Wrong!” He yelled. “That is a story told much later after I left the mortal world to stop people from fearing me. You are about to find out the real legend of The Sandman.
I laid in bed unable to move, my eyes held open by some imaginary force, staring at him in fear.
He held out his hand in front of my face and blew. I felt the wind on my face followed by the sand. The awful awful sand. Unable to close my eyes the sand blanketed my eyes. I could feel every grain of sand stick to my eyes.
Finally, I had control of my eyes again and started to blink uncontrollably. Each blink the sand grinded deeper and deeper into my eyeballs and eye socket. Each blink felt like shards of glass cutting my eyes. My eyes became watery and started to tear up but it wasn’t tears but blood leaking down my face. The pain engulfed my face but I couldn’t move, only involuntary blinking trying to clear the sand from my eyes. Each blink the sand cut farther and farther into my eyes. The pain became excruciating like someone had stuck a red hot fire poker in each eye. I wanted to scream out but nothing else worked on my body. Then the pain disappeared.
I assumed I had blacked out or went unconscious but that doesn’t happen in dreams and I wasn’t that lucky. Instead, I felt a weird sensation on my eyeballs then the feeling of water being poured into my eye. When it stopped, my vision started to appear again, blurry at first but clearing. I could see a sandy palm and fingers like I was being carried in The Sandman’s hand.
“The legend of The Sandman isn’t that he comes to put sand in your eyes to help you sleep, he comes to put sand in your eyes to steal eyeballs of kids who stay up too late.” He said. “I’m making an exception for you.”
He opened his palm and I could see my lifeless body, still in bed, not moving, the face covered in blood with empty holes as eye sockets. I am seeing myself from my own eyeballs. What the fuck, even for a dream this is fucked up. Luckily the pain had stopped, for now.
“Do you know what happens next in the legend? Do you know what I do with the eyeballs I steal” He asked like I could to respond. I didn’t know the answer but I knew I was about to find out.
“Right you are. Close your eyes, It’’s a surprise.” He laughed. “Get it? You can’t! You have no eyelids. Hahaha”
Excuse me for not thinking the joke is funny, being the butt of the joke.
“He pointed my eyes toward the moon and asked, “Do you like The Dark Side of the Moon?”
What the hell does the Pink Floyd album have to do with anything? Who doesn’t like it?
“Great. Let’s take a trip there. You’re dreaming so we can be there in, what would you say, a blink of an eye?”
Fucking funny. A moment later, we were on the dark side of the moon. It looked like the moon, but dark. He walked into a crater and I started to hear cries. Not like human cries, more like an animal cry. Not just one animal but a bunch. The cries got louder and louder. Even in a dream, I knew something bad was about to happen.
We finally arrived at what I would call a nest. Not your typical earth nest, but an enclosure that held a bunch of giant ugly bird-like featherless babies. Not dinosaur big, but big enough. Each bird-like creature was lifting its beak up in the air crying for its parents to bring it back food. What the fuck kind of food was available on the moon or in space is beyond my understanding, but that’s exactly what my eyes were seeing.
“After I steal the eyeballs, I bring them back here and feed them to the birds. In your world, you may throw bread out to the birds for a treat. In my world, I feed them your eyes.”
Fuck. Can I wake up now? I really don’t feel like being eaten by a giant alien baby bird thing.
“The legend says I fed them to my children, but that is the part they got wrong.” He said. “Sweet dreams, prince.”
He tossed my eyes into the air into the waiting mouth of one of these creatures. I saw it’s beak close as my eyeballs exploded into a gooey mess.
The dream ended and I woke up in a panic. I tried to open my eyes but they were sealed shut. I lifted my hands, happy I could move again, and felt my eyelids crusted over with sand. I cleared them the best I could but needed a warm compress to clean all the salt out. When I finally opened my eyes, they hurt. Everything had happened in the dream, but somehow my eyes felt sore.
I thought back to what I said and heard in my dream, “It is just a dream, nothing can hurt me there.” It is true, I wasn’t really hurt, but I’ve never woken up feeling pain I got from a dream. What is going on?
Still, If I dreamed, that means I slept! A nightmare isn’t so bad if I get real sleep. The dream felt like it lasted hours, a few more nights of this and I will have a somewhat normal sleep schedule and feel rested. I looked at the clock to see it was 4:30. I slept 12 hours and 15 minutes. Amazing!
I opened the door to my room and walked into the kitchen and it was still dark. That can’t be right. It should be 4:30 pm, the middle of the afternoon. Did I sleep for 24 hours straight? I looked at my phone and saw the date. My heart dropped. I had only slept for 15 minutes. It is like dreams take place in another dimension where time doesn’t exist. The Sandman was able to torture me for hours in dream time while allowing me to sleep for a few minutes. I cried. Seriously, I cried like a baby.
He held up his end of the bargain, I can fall asleep any time I want to, except now I am afraid to go to sleep. Everytime I fall asleep, he takes me away to his realm and gives me nightmare after nightmare. Every dream is one where he does something horrible to me and my dream self feels every bit of excruciating pain. And he never allows me to sleep more than an hour at the most.
I eventually accepted my fate. He is going to torture me, but it is all a dream. I will wake up feeling mostly normal. Then things changed. It is like he knew I had stopped fighting, so he found a new way to hurt me. Instead of hurting me in my dreams, he started to make me watch him hurt people I loved in their dreams. I didn’t think it was real until I heard from my sister about how my niece has been having terrible nightmares and refusing to go to sleep. When she described her dreams, I already knew, because I was there too.
That has been my life for the past however many months. Instead of trying to take medicine or listen to music or having The Sandman put me to sleep, I try to use my insomnia to stay awake for as long as my body will withstand it. I drink coffee and energy drinks, I take adderall, but eventually sleep always comes, even if for short periods. No matter how hard you fight it, your body will always sleep, and the Sandman will be there waiting on me.

We are not even in a bull market yet. Usually these things happen when there is a lot of hype. ZigmaBit is scammer company with fake mining rigs to basically scam you. Their selling website is https://zigmabit.com/ , please don't even click the link. We do not want to give them any traffic, just watch the video down below.
They have listed 3 miners on their website:
  • ZigBit 2.0
  • ZigBit 3.0
  • ZigBit 5.0

https://preview.redd.it/406xtn2l3cb41.jpg?width=1676&format=pjpg&auto=webp&s=4933fa05a303be6ece49fa37c4e8845fa8636605
Which of course doesn't exist. They recommend that these miners will make some crazy gains, which of course will not happen. As these miners are fake. Seeing the specification makes me think these guys know very little about crypto currency mining. So for example the specification they are advertising on ZigBit 5.0 is :
  • Bitcoin-2000 TH/s
  • Litecoin-300 GH/s
  • Ethereum-75 GH/s
  • Dash-50 TH/s
  • Power Consumption-2400W
  • Power Socket 110V-240V
Now you understand what im talking about, seriously 2000 TH/s mining Bitcoin at 2400w (where the latest Antminer S17 is 72Th/s), or mining ETH and the profit is so big that it will cover the miner cost faster then month. And another thing, they using the same hardware to mine multiple currencies which every one of them needs different hardware. Worst thing is that people will loose money, and most likely some of them already did. People think they will get rich after buying this miner, which they will never receive. Their fake products look so bad, their cheapest version ZiBit 2.0 looks like an ATX power supply.

Few things to also note is :
  • They have support chat on their website. I did send them a message and got response after about 20 minutes. So they told me that they only accept crypto currency, and the products are shipped from United Kingdom. My last line of the chat was "im coming for you you'll be in jail soon ".
  • When you google miner name, there is few websites coming up describing how great is their product. This most likely is owned websites for this scammer or this is purchased content posts.
  • Last thing is that i tired to do checkout on one miner, there is btc address which has already received 7btc. Im not sure if this is some people got already scammed or this is fake volume, hope this is fake volume https://www.blockchain.com/btc/address/1C4RSshoK9veR4jCNStqF32QARS5oGnmzw . Hope none is scammed.
Sad to see that there is such kind of people who makes money on scamming others. Man karma is there , i believe it will come for you sooner or later.

Cruzbit Is Celebrating Its First Year

The cruzbit blockchain has now been operational for its first full year. Block 0 was mined on Saturday, June 22, 2019 at 3:12:36 AM GMT, and the network has since mined just short of 67,500 blocks without notable issue.
Cruzbit is an all new codebase written in Go, designed to adopt the same behaviors as Bitcoin but with a strict focus on simplicity. The protocol uses established and mostly ubiquitous technologies such as WebSockets for connection, and JSON objects for both block and transaction storage, as well as in message transmission. The overarching principal is that developers should not need to spend their time becoming experts in the project in order to start developing upon it.
The community invite you to have a look at our project, and help us celebrate our first successful year!

cruzbit: A simple decentralized peer-to-peer ledger implementation. Currently ~100 GH/s nethash.

Hello everyone,
I'm a long time bitcoin fan/user. For years I thought about rewriting bitcoin to be as simple as possible. There is a fair amount of complexity to the canonical bitcoin implementation that didn't strike me as strictly necessary. It makes understanding and working with the protocol difficult. I had some time recently, so I finally decided to implement what I thought was the simplest version of bitcoin that could exist. cruzbit is what I ended up with.
Project: https://github.com/cruzbit/cruzbit
In addition to simplicity, I wanted everything I used to be standard. I wanted an average developer to be able to run cruzbit and immediately start working with the protocol and talking to their client.
Highlights:
No premining or any of that funny business. The memo field of the coinbase transaction of the genesis block is timestamped with the bitcoin blockchain's tip block hash at the time of its creation. The client currently has built-in support for mining with Nvidia ALL GPUs (now has CUDA and OpenCL support.) The network has been up for just over a month.
Any/all feedback is much appreciated. Would love to have some new miners join us. Take it easy!
Third-party block explorer: https://cruzbase.com/
Third-party site with tons of links+info and binaries (but we suggest building yourself, it's easy!): https://cruzb.it/

Need some troubleshooting help! Riser 008s and R3c

This project isn't for gpu mining but I know these risers are mainly used for this purpose so I thought I might get some good feedback here. My project is that I have an itx board with a single x16 pcie slot. It also has 3 m.2 pcie gen3 x4 slots. I have one free m.2 slot and wanted to convert that to x16 via riser. I wanted a 2nd low power silent gpu added to the rig. I went with the fanless msi 1030. It has a max draw of ~30w so I figured sata power would be safe. I purchased this and this to test with. Neither work!! So it must be something on my end?? The first part is fairly standard, the difference being I'm going to a m.2 slot where most of you are coming from x1 or x4. "In theory" this should just work! I'll start with the 2nd part since it's very simple: m.2 connector -> x16 socket + sata power. I hooked this up, seated the gpu and booted up. Nothing. Not even bios. I pulled the gpu and booted. Bios worked and booted up (running a 1080ti direct on the board). Installed the gpu back and nothing. I bought the 1030 used so I pulled the 1080ti and installed the 1030 direct to the mb. Works! So then I thought maybe the riser is bad or that sata power is insufficient seeing that most gpus would also have 6+8pin direct whereas mine has no external power. So I swapped risers out. This time the 008s with additional power connectors. Exact same thing. First I powered via pci only. Then sata+pci. And finally sata+pci+molex. In all situations the red led lit up. In all situations if I do not have the gpu plugged in it boots up fine. The strange thing is I never get into bios. No speaker or post lcd on this board so my troubleshooting is limited. And to note I test both gpu hdmi ports just to make sure one vs the other was set to primary. I got lazy and just looked at my mouse to light up to see if it booted. The mouse stayed dark, implying it never posted. Any help would be greatly appreciated! solved I have two m.2. ports which are pcie only. I have 1 port that is pcie/sata. the suggestion by u/sqrtlurface was to use the pcie/sata port and now the 1030 is being recognized in both linux and windows.

Top 10 Affiliate Programs to Earn Bitcoin

Top 10 Affiliate Programs to Earn Bitcoin

https://preview.redd.it/r59lj11bjjx31.png?width=563&format=png&auto=webp&s=f2ddf550d8fc01e63928de67693c2c2c15d125da
When we launched the Redeeem affiliate program we did a lot of research on other crypto companies, and what their affiliate policies were. We studied the many structures to an affiliate program, and we made a list of the top 10 crypto affiliate programs.
A few popular affiliate program models:
  1. Recurring Revenue Model - you have a unique URL affiliate link, and when you send it to people their account is linked to yours, and you get a percentage of whatever they spend or trade during their time. Sometimes this can be time limited (for 30 days), but typically goes for the life of the person you refer. Typically referral fees are taken from the company, so the company might advertise as 30% of Company's revenue, or it may say 1% of money spent on the platform.
  2. Initial payout Model - this is the most popular and simplest model for paying affiliates. A simple pay per sign up, typically between $5 and $15 per sign up you get. However, rarely will you get paid just for the signup, instead the new user must complete some "engaging action" on the website - a purchase, a trade, or a post.
  3. Multi-tiered Revenue Model - this is an extrapolated model from the recurring revenue model, where there are multiple tiers, or levels, so you get paid for the people who get referred by the people you refer. Typically it's a smaller % for the indirect tier, since you didn't do any work, but it does incentivize people to find the power players and refer them to the website.
Below are the Top 10 Affiliate Programs to Earn Cryptocurrency that we've found. Granted there are many affiliate programs out there, but if you're looking to start a blog, Youtube channel, or other content idea to get paid through affiliate links, check these out first.

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One

Cosmos — an early in-depth analysis at the ecosystem of connected blockchains — Part One
This is part one of three articles where i will discuss what i have learnt whilst looking into Cosmos. I will provide links throughout the article to provide reference to sections as well as a list of sources at the bottom of the article for you to look into specific areas in more detail if required. Hopefully it will be useful for those interested in learning more about the project.
Cosmos is still very early in development process with components such as IBC which connects two blockchains together currently in research / specification stage, as a result can change by the time its released.

What is Cosmos?

Cosmos is a network and a framework for interoperability between blockchains. The zones are powered by Tendermint Core, which provides a high-performance, consistent, secure PBFT-like consensus engine, where strict fork-accountabilityguarantees hold over the behaviour of malicious actors. Cosmos is not a product but an ecosystem built on a set of modular, adaptable and interchangeable tools.
In Tendermint, consensus nodes go through a multi-round voting proposal process first before coming to consensus on the contents of a block. When 2/3 of those nodes decide on a block, then they run it through the state transition logic providing instant finality. In current proof of work consensus for Ethereum, the consensus process is inverted, where miners pick the transactions to include in a block, run state updates, then do “work” to try and mine the block.
Tendermint BFT can handle up to thousands of transactions per second (depending on the number of validators). However, this only takes into account the consensus part, the application layer is the limiting factor though. Ethermint (described below) has achieved up to 200 tps to give you an idea of the speed available per blockchain which is significantly more than current versions of Ethereum and Bitcoin etc.
The Tendermint consensus is used in a wide variety of projects, some of the most notable include Binance Chain, Hyperledger Burrow. It’s important to note though that just using Tendermint consensus doesn’t mean they can connect to other chains with the cosmos ecosystem, they would need to fork their code to implement IBC as a native protocol to allow interoperability through IBC.
see https://raw.githubusercontent.com/devcorn/hackatom/mastetminfo.pdf for high res

The Tendermint consensus algorithm follows a traditional approach which relies on all validators to communicate with one another to reach consensus. Because of the communication overhead, it does not scale to 1000s of validators like Bitcoin or Ethereum, which can have an unlimited number of validators. Tendermint works when there are 100s of validators. (Cosmos Hub currently has a maximum of 100 validators and the maximum tested so far with Tendermint is 180 validators)
Therefore, one of the downsides of a blockchain built using Tendermint is that, unlike Bitcoin or Ethereum, it requires the validators to be known ahead of time and doesn’t allow for miners to come and go as they please.Besides this, it also requires the system to maintain some notion of time, which is known to be a complex problem in theory. Although in practice, Tendermint has proven this can be done reasonably well if you use the timestamp aggregates of each node.
In this regard, one could argue that Tendermint consensus protocol is “less decentralized” than Bitcoin because there are fewer validators, and they must be known ahead of time.
Tendermint’s protocol guarantees safety and liveness, assuming more than 2/3 of the validators’ voting power is not Byzantine (i.e., malicious). In other words, if less than 1/3 of the network voting power is Byzantine, the protocol can guarantee safety and liveness (i.e., validators will never commit conflicting blocks at the same height and the blockchain continues to make progress).https://www.preethikasireddy.com/posts/how-does-cosmos-work-part1
To see the process of how Tendermint works please see this diagram as well as more info here

Sovereignty

Cosmos goal is to provide sovereignty through governance to developers by making it easy to build blockchains via the Cosmos SDK and provide interoperability between them, using Tendermint consensus. This is their main differentiator compared to competition like Polkadot and Ethereum 2.0. Ethereum 2.0 and Polkadot are taking a different approach by only using shared security, where there is a root chain which controls the security / prevents double spending for all connected blockchains.
In Hub governance all stakers vote, the validators vote is superseded if the delegator votes directly
Governance is where all stakers vote on proposals to determine what changes are implemented in the future for their own blockchain, stakers can either choose to delegate their vote to the validator or they can instead vote directly. Without sovereignty all DAPPs share the same underlying environment. If an application requires a new feature in the EVM it has to rely entirely on the governance of the Ethereum Platform to accept it for example. However, there are also tradeoffs to having sovereignty as each zone is going to need a way to incentivise others to validate / create blocks on the Zone by running Full Nodes. Whilst it may be easy to create a blockchain using the cosmos SDK and to mint a token, there are the legal costs / regulation associated with creating your own token. How are you going to distribute the tokens? How are you going to list them on exchanges? How are you going to incentivise others to use the token without being classed as a security? All of which have led to a significant reduction in the number of ICOs being done. With every zone needing their own validator set, there’s going to be a huge number of validators required each trying to persuade them to validate their zone with only a finite number of validators available.
Each Zone / App is essentially a mini DAO and not all are going to be comfortable about having their project progress been taken out of their hands and instead relying on the community to best decide on the future (unless they control 2/3 of the tokens). The Cosmos Hub has proved this can be successful, but others may be risk averse to having their application be a mini DAO. Should someone / competitor acquire 1/3 of the tokens of a zone then they could potentially prevent any further progress being made by rejecting all governance votes (this would be very costly to do on the Cosmos Hub due to its high amount staked, but for all the other less secure zones this potentially may be an issue).
Security for some zones will likely be a lot lower with every developer needing to validate their own blockchain and tokenise them with POS with no easy way to validate the setup of a validator to ensure its secure. Whilst the Cosmos hub is very secure with its current value staked, how secure zone’s will be with significantly less staked remains to be seen. Whilst providing soverignty was Cosmos’s main goal from the start, they are also looking at being able to provide shared security by having validators of a connected Hub also validate /create new blocks on the connected zone’s blockchain for them as well. They are still going to need some way to incentivise the validators to this. Another option is if the developers didn’t want to create a token, nor want sovereignty etc, then they could just build a DAPP on the EVM on a zone such as Ethermint.
As can be seen their are potential advantages and disadvantages to each method, but rather than forcing shared security like Ethereum and Polkadot, Cosmos is giving the developer the choice so will be interesting to see which they prefer to go for.

Layers of a blockchain

From an architecture standpoint, each blockchain can be divided into three conceptual layers:
  • Application: Responsible for updating the state given a set of transactions, i.e. processing transactions.
  • Networking: Responsible for the propagation of transactions and consensus-related messages.
  • Consensus: Enables nodes to agree on the current state of the system.
The state machine is the same as the application layer. It defines the state of the application and the state-transition functions. The other layers are responsible for replicating the state machine on all the nodes that connect to the network.
The Cosmos SDK is a generalized framework that simplifies the process of building secure blockchain applications on top of Tendermint BFT. The goal of the Cosmos SDK is to create an ecosystem of modules that allows developers to easily spin up application-specific blockchains without having to code each bit of functionality of their application from scratch. Anyone can create a module for the Cosmos SDK and using ready built modules in your blockchain is as simple as importing them into your application.
The Tendermint BFT engine is connected to the application by a socket protocol called the Application Blockchain Interface (ABCI). This protocol can be wrapped in any programming language, making it possible for developers to choose a language that fits their needs.

Hub and Spoke Topology

Cosmos follows a hub and spoke topology as its not feasible to connect every zone together. If you were to connect every blockchain together the number of connections in the network would grow quadratically with the number of zones. So, if there are 100 zones in the network then that would equal 4950 connections.
Zones are regular heterogenous blockchains and Hubs are blockchains specifically designed to connect Zones together. When a Zone creates an IBC connection with a Hub, it can automatically access (i.e. send to and receive from) every other Zone that is connected to it. As a result, each Zone only needs to establish a limited number of connections with a restricted set of Hubs. Hubs also prevent double spending among Zones. This means that when a Zone receives a token from a Hub, it only needs to trust the origin Zone of this token and each of the Hubs in its path. Hubs do not verify or execute transactions committed on other zones, so it is the responsibility of users to send tokens to zones that they trust.
There will be many Hubs within Cosmos network the first Hub to launch was the Cosmos Hub whose native staking token is called ATOM. ATOM tokens are specific to just the Cosmos Hub which is one hub of many, each with their own token. Transaction fees for the Cosmos Hub will be payable in multiple tokens so not just ATOMs whereas other Hubs such as IRIS has made it so that all transaction fees are paid in IRIS for transactions on its hub.
As mentioned, the Cosmos Hub is one of many hubs in the network and currently has a staking ratio of around 70% with its token ATOM having a market cap of just over $800 million. IRISnet was the second Hub to launch which currently has around 28% bonded with its token IRIS which has a market cap of just under $17 million. The Third Hub about to be launched later this month has its token SENT which has a market cap of around $3.4 million. As you can see the security of these 3 hubs differ wildly and as more and more hubs and then zones are brought online there is going to need to be a lot of tokens / incentivisation for validators.
Ethermint
Standard Cosmos zones / hubs don’t have smart contract functionality and so to enable this, as the Application layer is abstracted from the consensus layer via ABCI API described earlier, it allows Cosmos to port the code over from other blockchains such as Ethereum and use it with the Tendermint Consensus to provide access to the Ethereum Virtual Machine. This is what is called Ethermint.
This allows developers to connect their zones to specialised zones such as Ethermint to build and run smart contracts based on Solidity, whilst benefiting from the faster performance of the tendermint Conensus over the existing POW implementation currently. Whereas a normal Go Ethereum process runs at ~12.5 transactions per second (TPS), Ethermint caps out at 200 TPS. This is a comparison against existing Ethereum speeds, whilst obviously Ethereum are working on their own scaling solutions with Ethereum 2.0 which will likely be ready around the same time. Existing tools / dapps used on ethereum should easily be able to be ported over to Ethermint by the developer if required.
In addition to vertical scaling (with the increase in tps by using Tendermint consensus), it can also have multiple parallel chains running the same application and operated by a common validator set. So if 1 Ethermint zone caps out at 200 TPS then 4 Ethermint zones running in parallel would theoretically cap out at 800 TPS for example.

There is a huge number of developers / apps currently built on Ethereum, should a developer choose to migrate their DAPP over to Ethermint they would lose native compatibility with those on Ethereum (except through Peg Zone), but would gain compatibility with those running on Ethermint and others in the cosmos ecosystem.

IBC

IBC stands for inter-blockchain communication protocol and is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, authenticated communication between modules on separate distributed ledgers. Ledgers hosting IBC must provide a certain set of functions for consensus transcript verification and cryptographic commitment proof generation, and IBC packet relayers (off-chain processes) are expected to have access to network protocols and physical datalinks as required to read the state of one ledger and submit data to another.
In the IBC architecture, modules are not directly sending messages to each other over networking infrastructure, but rather creating messages to be sent which are then physically relayed via “Relayers”. “Relayers” run off-chain and continuously scan the state of each ledger via a light client connected to each of the 2 chains and can also execute transactions on another ledger when outgoing datagrams have been committed. For correct operation and progress in a connection between two ledgers, IBC requires only that at least one correct and live relayer process exists which can relay between the ledgers. Relays will need to be incentivised to perform this task (the method to which hasn’t been established as of this writing)
The relay process must have access to accounts on both chains with sufficient balance to pay for transaction fees. Relayers may employ application-level methods to recoup these fees, such by including a small payment to themselves in the packet data. More information on Relayers can be found here

https://preview.redd.it/qr4k6cxtmba31.png?width=1100&format=png&auto=webp&s=d79871767ced4bcb0b2632cc137c118f70c3863a
A high-level overview of the process is that Zone 1 commits an outbound message on its blockchan about sending say 1 x Token A to Hub1 and puts 1 x Token A in escrow. Consensus is reached in Zone 1, and then it’s passed to the IBC module to create a packet which contains the reference to the committed block, source and destination channel/ connection and timeout details and is added to Zone 1’s outbound queue as proof.
All relayers (who run off-chain) are continuously monitoring the state of Zone 1 via the Zone 1 light client. A Relayer such as Relayer 1 is chosen and submits a proof to Hub1 that Zone 1.
Hub 1 then sends a receipt as proof that it has received the message from Zone 1, relayer1 sends it to Zone 1. Zone 1 then removes it from its outbound queue and sends proof via another receipt to Hub1. Hub1 verifies the proof and mints the token.

This video below explains the process in more detail as well as covers some of the other points i raise later in this article so worth a watch (time stamped from 22:24 to 32:25) and also here from 38:53 to 42:50
https://youtu.be/5h8DXul4lH0?t=1344
Whilst there is an option for UDP style transfer where a zone will send a message to a Hub and it doesn’t care whether it gets there or in any order etc, Token transfers are going to require the TCP style connections in IBC where there is a send, receipt and then another receipt as explained above. Each Send, receipt followed by another receipt is going to take at least 2 blocks and so using Cosmos Hub block times as an example with 6.88 second block times a transfer between one zone and hub could take a minimum of 41.28 seconds. You also then have to factor in the amount of other transactions going through those at that time and relevant gas price to see whether it is able to use 2 consecutive blocks or whether it may take more. This is also explained in this video “ILP Summit 2019 | Cosmos and Interledger | Sunny Aggarwal” (time stamped) from to 12:50 to 15:45

In Part Two we will look at potential issues with multi hop routing, token transfers across multiple routes and Peg Zones, whilst also looking at other interoperability solutions that would resolve some of these issues and compliment the cosmos ecosystem. Part Two can be found here

I have a $663 credit at the bitcoinstore. Let's build a mining machine (or start to)

I ordered something and they don't have it anymore. It's not important why I have this credit. I decided to repurpose the $663 to build a bad ass PC that will
1) mine XPM now
2) have the ability to support GPU's later
3) be an all around flexible crypto-computer for unforseeable things, which is impossible, but still
that means I don't really need GPU's right now. I do want to the ability to support them later xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
edit. we want gpu's
If I wanna use the BTC store credit I can do this.
It is 2x PCIe but its my first build. From what I have learned as an engineer, the first build is not your last. Maybe my next machine can be a 6 slot masterpiece. I wanted all those awesome things, and the lack of BTC store credit was making my wallet hurt. I think this is a nice start. Thanks to those who helped!! Fuck yes. XPM BABY WOOOO TO THE MUHTHA FIN MOOOOOOOOOOOOOOOOOOOOooooooooooooooooooooooo
thanks to koooooj for telling me what is up and educating and thanks to mechmax for doing my shopping for me and making proper financial decisions for myself. Prolly good advice to take the free credit and hold off on binoculars I don't need.
