Mining good to this gamer

Last year I bought a Rx 480 for $200, before I turned around and sold it for $400 after a few months. With that $400, I bought a Vega 56 on launch.
I've just sold that Vega 56 for $840. I essentially just exchanged an RX 480 for a 1080ti. Thank you miners!

Want to end GPU crysis? Here's the solution

I know that you're all angry about GPU crysis. First, let me introduce myself : I was a part of the PCMR but now I have no time to play anymore, and bad internet does not help. So I had my 290x layin' around and free electricity in my small student room. I was thinking, free electricity plus graphics card means money, so I started mining. I bought 0 graphics card. As you probably know, all the Ethereum miners have to share the benefits (even if they're not in a pool), the more miner there are, the less benefits you get. A lot of miners (not me) pay for electricity which has a fixed priced. If they don't make money anymore they will stop mining and sell their GPU. All you have to do is start mining when you're not playing. If all the PCMR community of the world start doing this, we can change things. If you're worried about electricity just turn off your heater, it's not wasted electricity if you use the heat.

A story from a cloaky camper and an attempt to build a beast mode multi-boxing server.

Hello Nerds!
Some of you may know me, some may not. Those that do will know I offer cloaky camping services over new eden. I do camping contracts / extort renters and focus my time hunting botters when the contracts are quiet. I offer PvP entities access to my cyno network to get dank kills and big escalations. From super carriers to Rattlesnakes.
The thing that got me into camping was hunting bots back in the dronelands a few years ago. I realised the most effective way to hurt them was to camp them 23/7, follow them around using locator agents. Eventually they had to rat with me in system. When they did I setup bubble traps etc and dropped blops and cleaned them up.
The 2nd thing I love about cloaky camping is the ability to counter Alliances (i feel its overpowered) intel channels / networks. Think about it. They have multiple intel toons dotted around the entrances to their pipes reporting hunters coming into the pipe allowing the PvE players to warp off and safe up. They even use external programs to collect this intel and give audible alerts. Cloaky camping is just the polar opposite. Dotting toons in their ratting pocket and giving me intel on whats going on in their system. As long as local chat exists so will cloaky camping. I'm pretty confident CCP share the same thought.
People probably think cloaky camping is easy. You are wrong. The prep work and behind the scenes work that goes into it is pretty immense. You are about to find out.
The hardware i'm currently running the 60 clients on is as follows:
Camper1: Screenshot of 30 Clients Layout
How do you pay for 60 toons
I started with 10 campers and made ISK by other means. When I made new campers I invested ISK and started to Skill extract and plexing the toons. I also make a decent amount from people who pay me to camp others.
The Setup  
I manage the clients window positions and CPU allocation with ISBOXER. Its legal to use as long as you don't use input broadcasting. I boot up the clients with ISBOXER EVE Launcher. I copy the window positions / chat channels etc over using garpaui. I use remote desktop to manage the clients light cynos etc.
Example here
On both motherboards I had to under clock the processors as they were drawing too much power from the motherboard and causing the chipset to overheat. I think these motherboards are not beefy enough to support these 8 core processors. It caused the CPU to throttle reducing the clock speeds to 1.3Ghz and causing lag issues. I solved this problem by reducing the clock speed from 4Ghz to 3.6Ghz and reducing the CPU voltage. This reduced the heat by a really good amount and stopped the problems.
However, Me being me I wanted to expand and the camping pcs were running at full chat. So I needed a better piece of hardware to host these 60+ clients. So, while at Fanfest, I bidded on this R820 Server on ebay and won!
The hardware should be able to support multiple clients. However i'm not too sure how eve is going to behave when I try and open 60 instances all in one OS. I have set myself up for a hell of a challenge! However, I feel like I got a pretty good deal on the server and DELL hold their value. I'm sure I can re sell it if the project fails.
Things to work out:
Things I will teach you guys
I'm learning too so your help input would be awesome! First question. Shall I just update this reddit post each time or create some sort of blog?
Old AMD FX Rigs
New Kit / with various bits I gathered to get started
Update 23/04/18
I have made some decent progress on this crazy project. I will give some breif updates here. I will get a blog up and running to post full details with how to's etc. Its probably way to long for reddit.
I have successfully installed some GPU's into the R810 AMD R9 280x and Nvidia GTX 970. I soldered some PCI-E cables to the PDB and it worked fine. The GTX sits nicely in the chassis however, the R9 280X is external atm using a PCIE x1 to x16 riser (from my bitcoin mining). Also I have managed to enable and use them both with passthrough in ESXI 6.5. Yes the GPU works with a x1 adaptor. WTF!
Freezing Problem with a single os install
If I try and run more than 40 clients in a single OS I the system freezes when loading up client 41. I have tried the following:
I cannot see why it is freezing. Is there any way to gather logs for the client? It doesn't appear to be a resource problem. Plenty of RAM / CPU and HDD isn't going crazy.
Here are some pics of the current progress:

It always breaks my heart when someone buys a r9 290x in my computer shop but it's not for gaming...

I work in a computer store as a salesman and recently, the mining industry has grown up because everyone noticed the easy money you can do by just making your card(s) run 24/7. Personnally, I'm not a huge fan of that. I think it's not really worth it in the end because it breaks video cards, costs a lot of power and you have to payback your stuff but whatever, it's not what I want to discuss.
I mean, all these smexy boxes leaving and it's not even for playing games! 280xs, 290s, 290xs, all those! You could have a dream computer, playing on X monitors and it's just gonna go die in hell.
I guess it's just me that's being butthurt cause I'm waiting for an after market 290x but it still gets to me :3

Idle PC's

I have a classroom of 20 PC's with a leased line, the classroom is only used once a month, is there some software I can install other than gomezpeer that can make me some money on those machines whilst they aren't in use?
I don't pay for the electricity so leaving them on is no problem, I can also install the software when the class is finished and uninstall the day before if the software uses a lot of resources.

280x or 770

So I'm working on finishing off my component list for the computer that I want to create. However I am stuck between an Asus r9 280x and an Asus 770. Anyone have any insight on which I should go with? There's only a $13 price difference and its hard for me to figure out the best out there.

Zilliqa: A Game-Changer When It Comes To Blockchain Scalability

DISCLAIMER: I am in no way associated with the Zilliqa team. Neither am I a financial advisor, nor is this meant to be financial advice. Whatever follows, just reflects my understanding of the project, and my personal opinion on its future outlook.
Recently we have seen a lot of debate surrounding scalability of public blockchains, partly stemming from the CryptoKitties fiasco. CryptoKitties is an online game, created by Vancouver-based Axiom Zen, that allows users to purchase, trade, and breed digital kittens. Soon after its public release on November 28, the game took the cryptocurrency world by surprise, accounting for about 11% of total transactions on the Ethereum network, the blockchain that the CryptoKitties application is built on. The volume of traffic on the platform within the first week of its release was enough to put serious strain on the Ethereum blockchain, clogging the network, causing significantly slower transactions times and higher transaction costs for all the blockchain users.
Some may argue that having an application like Cryptokitties on the Blockchain is frivolous, since the application is a non-coin related gaming platform. However, I think that this is a great application of the Blockchain technology, and why the technology is so disruptive. In fact Ethereum Co-founder, Vitalik Buterin, himself tweeted in support of the application, emphasizing on the value that the blockchain technology brings.
So, maybe instead of asking the question: ‘Should we have an application like CryptoKitties on a public blockchain?’, we should really be asking the question: ‘Shouldn’t public blockchains be more scalable to real world application?’. The fact is that, as of today, blockchains are limited in their ability to scale, which some argue is the biggest technological barrier to global adoption of the technology.
Consensus protocols on existing public blockchains (Ethereum, Bitcoin, Neo, Ripple etc.) have a critical requirement for validation of transactions: every participating node on the network has to validate each transaction sequentially, and then store transactions on the ledger, a copy of which is maintained by each node. This requirement is what imparts, to blockchains, their key characteristic —‘decentralization’.
However, in such a decentralized system, as the number of transactions on the network increases (with, for example, blockchain adoption), the need for additional nodes, to process and store transactions, also increases. As the number of nodes on the network increases, the data for each transaction has to travel a lot more before being validated and stored by ALL the nodes on the network. Therefore, the network does not scale well as more nodes are added to the network due to the inter-node latency that increases logarithmically with each additional node. In effect, blockchain scalability reduces as the network size increases.
Public blockchain consensus protocols, that operate in this fashion, are forced to choose decentralization over high transaction throughput.
Today, approximately 900 distributed applications (dApps) are built on the Ethereum Network. With a transaction throughput of about 15 transactions-per-second (tx/s), Ethereum is barely capable of handling the current transaction volume, and would have to scale significantly to be able to handle the expected transaction volume in the near future. The Bitcoin network is even worse in terms of transaction throughput, processing only about 4 to 7 tx/s. Similar is the story for all the existing public blockchain platforms, with some being slightly more scalable than others, but all glaring into a future where blockchain transaction throughput could be a severe bottleneck, hindering mass adoption of the blockchain technology.
Researchers from the National University of Singapore (NUS) have founded a blockchain startup called [Zilliqa]( This new blockchain uses the ‘sharding’ technology, that is set to achieve Visa and MasterCard level transaction throughput of about 4000 tx/s.
Zilliqa is a high-throughput public blockchain platform designed to scale to thousands of transactions per second. The reasons, I believe, Zilliqa stands out as a public blockchain platform suitable for global adoption are as follows:
Although Zilliqa’s team does not see the other existing public blockchains as competitors, and rather takes a more open approach towards them, facilitating a healthy environment of learning from each project and developing on it, I use the term ‘competitors’ here in the conventional sense to be able to compare Zilliqa head-to-head against the existing blockchains. The following comparisons are based on the information shared by Zilliqa’s team with the community.
Zilliqa versus Bitcoin:
Zilliqa versus Ethereum:
Zilliqa versus NEO:
Zilliqa versus EOS:
Zilliqa’s team consists of highly renowned scientists, entrepreneurs and engineers with significant experience in the blockchain domain and cyber-security.
The Chief Executive Officer (CEO) of Zilliqa, Xinshu Dong, has a PhD in Computer Science from the National University of Singapore (NUS), and is a practitioner in building secure systems. He has led several national cyber-security projects in Singapore, and has extensively published his research in renowned international conferences.
Prateek Saxena is the Chief Scientific Advisor for Zilliqa, and has a PhD in Computer Science from University of California, Berkeley. He is a research professor in computer science at NUS, and has received several premier awards such as the Top 10 Innovators under 35 (MIT TR35 Asia) in 2017.
The advisory board of Zilliqa also includes the prominent names in the blockchain industry, like Loi Luu — Co-founder of Kyber Network, Vincent Zhou — Founding Partner of FBG Capital, Nicolai Oster — Partner at Bitcoin Suisse AG, and Alexander Lipton — Founder and CEO of StrongHold Labs.
The highlights of Zilliqa’s roadmap are as follows: * Zilliqa has already released public testnet v1.0 * Public testnet v1.5 release is scheduled for Q1 2018 * Public mainnet release is scheduled for Q2 2018 * dApps release scheduled for Q3 2018
Zilliqa has a very active roadmap ahead, with the biggest event being its mainnet launch.
At the Token Generation Event (TGE), Zilliqa set the cap for contributors to 48,889 ETH, or US$ 22 million at a locked rate of US$ 450/ETH. Zilliqa’s tokens are called ‘Zillings’, or ZILs. ZIL price at the TGE was US$ 0.003877. Zilliqa has a finite supply of 21 billion tokens, of which only 60% (12.6 billion tokens) are generated at the TGE, and the remaining 40% (8.4 billion tokens) would be mining rewards over the next 10 years. The details on Zilliqa’s TGE can be found of Zilliqa’s official blog post regarding TGE.
The market cap of Zilliqa has grown from about US$ 22 million at the TGE, to US$ 49 million as of this writing, due to the increase in ETH price. Zilliqa’s public mainnet release is scheduled for Q2 2018. Considering the improvements Zilliqa’s public blockchain protocol adds to the technology in terms of performance, security and governance, and the experience and competence of the team behind the Zilliqa project, there is a huge upside on the price potential of ZIL.
In the short term, by the time Zilliqa’s public mainnet is released in Q2 2018, I think its market cap could easily be in the range of US$ 3 to 7 billion. With a circulating supply of 6.3 billion ZILs, this would mean ZIL price could be in the range of US$ 0.5 to 1.1, that is roughly 12,000 to 28,000% increase (120x to 280x) from the ICO price in US$ terms.
In the long-term, it is next to impossible to predict ZIL price with any considerable level of certainty, due to the sheer number of factors that could influence the growth and adoption Zilliqa’s public blockchain. Any attempts to make such predictions would be merely speculative, and should be considered so. However, it would be fair to say that for any public blockchain platform that is able to truly scale with global adoption, has a large developer community, is one of the preferred blockchains to host high throughput dApps, and does all of this in a decentralized and secure manner, having a market cap in excess of US$ 100 billion in the long-term would be a reasonable prospect.
The bottom line is that, for Zilliqa, truly, sky is the limit. And this is what makes Zilliqa’s future potential so exciting and worth keeping an eye on!
Full disclosure: I am invested in Zilliqa for the long-term, and I plan to buy more when Zilliqa trading goes live.
