Well that was a fun call I just had.
Owner of the company I freelance for: Hey I forgot to tell you something.
Me: What?
Owner: I bought you a plane ticket to fly to Puerto Rico. You're heading out in a month.
Me: What?! Why????
Owner: To set up cryptocurency mining rigs.
Me: Just because I know a bit about mining doesn't make me an expert.
Owner: We have $80k in our pocket in investments from outside parties, with another $20-30k on the way. You get 20% of the coins mined for as long as you manage it.
Me: So we're gonna set up several rigs, utilizing a b250 motherboard, g4400 CPU, 8GB of RAM and 10 GPUs each. We'll have AMD rigs for monero and Nvidia rigs for Ethereum and others. We'll use awesome miner for profitability switching on the fly. Each machine is probably going to be $5k each, possibly $4k with bulk discounts. We'll need at least 1500W per rig for power, 2000W to be safe, so we need to make sure we have ample power delivery to the mining warehouse.
Owner: I thought you weren't an expert?
Me: I'm not, but when there's money involved my motivation to Google goes into overdrive.28 -
EDIT: devRant April Fools joke (2021)

Hey everyone,
@trogus and I are happy to make an exciting announcement. With the rapidly increasing success of NFTs, we've decided the devRant community shouldn't miss out on this compelling new paradigm for user-generated content. So, we will soon be offering all rants as NFTs at auction.
To kick things off, we're going to first be offering the first ever rant posted to devRant (https://devrant.com/rants/489/...) at auction for a starting price equivelent to $100,000 USD. We think this is a fair starting price for such a significant piece of devRant history, and we anticipate the final sale price to be significantly higher.
We look forward to hearing everyone's thoughts on this new direction for the devRant community, and we can't wait to see the Rant NFT market take off!
Sincerely,
@dfox & @trogus

Bitcoin just went from $2600 to $1870
And ethereum is now $140
Cryptocurrency markrt capacity went almost from $100B to $60B14 -
The fucking SECOND i buy ethereum its price starts dropping.
//sidenote: yay 25k++, i wonder if trogus ever thought about adding a pet shark16 -
> be me
> spend 0.02 Ether (about €5) on one of those old-school MUD-style games
> send to the same Ethereum wallet from a previous purchase
> realize that the destination wallet changes for each purchase (probably to mitigate the fact that transaction history and contents in Ethereum wallets is entirely public)
> send an email to the game dev asking to return the transaction or pass it on to my player account
> *cricket noises*
About a week later, i.e. now:
*checks that Ethereum account that I accidentally sent that transaction to*
> $0 on it, transaction has been withdrawn
Now I couldn't care less about the €5 - it's only 2 beers worth - but what I do care about is honesty. Dear Chat Wars admin, that money wasn't yours. Also, I am one of those players that plays very few games but tends to commit to those I do play. The last one I played, I spent several hundreds of euros on over the couple of years I played it. I could've probably paid for your servers, spare time development and then some. But obviously not anymore. Choosing a quick grab of €5 over a relatively steady source of income from someone that tends to financially support what he likes... Re-evaluate your life choices.
Just like that incident with the stolen flash drive that was worth only €10... I couldn't care less about the raw value of them, but I do feel very disappointed in humanity when people go for a quick grab of such worthless things.5 -
So, my UpWork account request is rejected, with a reason that
"already many freelancers with a similar skillset to yours".
In skills I entered
"AngularJS, ASP.NET MVC, .NET Framework, C#, jQuery, Semantic UI, Bootstrap"
Then I resubmitted the request with by adding blockchain and Ethereum.
Again rejected.
What should I do 😫
I guess I never can start freelancing.21 -
So, went to 3 hackathons in the last 3 weeks. Won 2/3. Developed on Ethereum and some Iota for the most part. Loved this experience and many more to go. Idk what to say honestly, just blabbering :p13

Bought an Ethereum (yes, only one ☹️) in january at 9.90$. Now it's at ~180$. I should have bought more..

Recently, my friend and I participated in a hackathon and had the chance of building my very first Dapp. We call it FarmerChain. FarmerChain has a module called Farmer Bank. It's a simple wallet type contract simulating a "bank". I'd love some feedback from you guys. Any critiques/suggestions/ everything is welcome. Source code https://github.com/imshubhamsingh/...

Tried mining ethereum today. Just wanted to check that out, for the heck of it. Fired off a p3.16xlarge instance on AWS, 4 x Tesla V100 running at $12 an hour! It was an absolute beast. Anyway, kept it running for 9 hours and earned about $5 before shutting it down. Cost me $108 to earn that $5. Had a lot of credits expiring in a couple of days, so I wanted to burn them off anyway.
So crypto mining, not easy money.9 -

The only thing I studied from HTML is that you have to close anything you have opened.../>
I already had some experience with C++ and suddenly they suggested me to take a mentoring.
My mentor - Well, we're going to learn HTML.
- I'm busy. I'm learning python...
- What have you done? Did you learn the HTML?
- Eeh I need to do a neutral network project for the uni. Wait please...
- It's time to learn HTML.
- Eeh I have a deadline in these days. I have to make an Ethereum smart contract. Wait please...
- HTML!
- WAIT!
Finally I asked my mentor to stop this fucking recursion. I'm not going to learn it.

Just finished dumping all ethereum tranasctions into one big 30 GB csv.
Only thing left is to configure Apache Spark cluster.3 -
Me currently in my 3rd year of university: hears about blockchain from my friends, reads 5 pages of ethereum white paper; sees a cool machine learning project, watches 2 weeks of Andrew Ng's course; plays a cool game, downloads Unity and makes a hello world game; hears about wifi vulnerability, purchases an ethical hacking course.

Me to Me - I will Buy 1 Ethereum after Exams ( 8th Dec )
After Exam -
I will buy it soon.
Today -
Ethereum touched $7002 -
everyone glorifies ethereum and its smart contracts, but the actual build tools and overall development environment around it sucks balls.
when testing a contract locally with truffle develop and metamask, you have to reinstall metamask after every transaction because it gets out of sync with your local chain... people are seriously okay with working with this shit?3 -
Okay, so, my company does some stuff around blockchain. I had source for smart contract prepared before and it was on 'todo' queue. So, time for it, time to deploy on Kovan, time to test it on actual chain. Riiiight? Okay compiled no problem, deployed, no problem, i plug into several gui's ABI provided by compiler, and... Well..
I still do not understand why each and every gui prompted me to send view transactions (external view), instead of, well, eval them locally, i checked the ABI manually, it is correct, i stripped it down, it is correct, all up to spec.
I try older version of offline MEW, to have older web3.js with no success that thing works properly.
Every
Single
Web3.js based client
Behaved
Differently
And none behaved correctly.
I would, like, understand, if I didnt use official compiler, but official compiler should for F sakes be compatible with official client.
Today this stole 6 hours of my life, I didnt manage to solve it, and I am legitmitely pissed.
Im getting close to re-implement segment of web3JS to be able to do the tests I need to do.
Its not like I havent done it before.... -
Crypto:
What's your thoughts on Ethereum Name Service? Do you think this will take off?
ENS is basicly a decentralized DNS based on the Ethereum blockchain.
It seems like a significant piece of technology to me but I'm having a hard time to judge how significant or useful it will be and to whom.

Can anyone suggest me how I can learn building dapps in fortnight? I went through a lot of medium articles and dapp university but all of it was not enough for me.3

I started watching "Squid Games" this morning and well after the first round the players are given a chance to quit.
Which they do... But then come back.
Well, I bought some Ethereum a few weeks ago before crypto tanked...
But checking in this morning I'm now back to break-even...
And well feels like I'm gonna keep playing too... -
Thinking of making a project using the Blockchain to get better understanding of it.
Confused whether to use Ethereum Blockchain (Solidity) or Bitcoin Blockchain (bcoin API). Any help!1 -
Lol, I lost my ethereum wallet's mnemonic phrase. I lost 422 eth.
Then I realized I was using Ganache local blockchain whole the time.3 -
On page 19 of the ethereum yellow paper: http://gavwood.com/paper.pdf it defines the address of a wallet as: A(pr) = Β[96...255](KEC(ECDSAPUBKEY(Pr))), which is the right most 160-bits of the Keccak hash of the public key generated by the private key.
If I expose the public key to the network, do I allow people to impersonate me and sign transactions even though they don't have Tr, Ts, or Tw? My understanding is no, that without those values you can't hash the transaction.
Subsequently, this leads me to wonder if the purpose of the address (besides identifying users) to obscure the public key so that the private key is at a less risk of being reversed? Or can the public key of any address be captured?
If the public key of any address can be identified on the network or off network (without actually being the owner of that key), how do you do that? Are there any resources on how to perform this that are computationally easy?1 -
Hey guys, I have a question.
If you ever had to deal with parity (Ethereum node software) and ever ran archive node, you perfectly know how long this bastard synchronizes. For our server it took almost month. Well, today or yesterday parity decided to spontaniously blow up (or crash) corruptiong database manifest file which greatly undercut us.
Anyone knows any viable way to rebuild manifest file withoud doing full sync from a scratfch?
If anyone has any suggestions other than what 95% of internet say "well, delete your database and sync from scratch" Im happy to test if it will solve our burning burning issue.
I am sure there is some way to rebuild database, especially where it's manifest file that's corrupt (Ive checked it, for wtf reason parity decided to truncate the file when it crashed).
Database backend is written in rust, and is called rocks db.
EDIT: if helps, its archive fat database (fat db means it should be easier to recover?)4 -

It's about time we get a new internet (like in silicon valley TV show). Fully decentralised wherever possible. The fact that you need to spend ether for every write to the Ethereum Blockchain is not gonna help.

Online Multiplayer Mafia party game built on Ethereum.
Project Type: Existing open source project
Description: I found that most of the blockchain game projects in this space are using traditional web2 technology for hosting gameplay. So, we decided to create a game that utilizes web3 technologies as much as possible for our project and create services like real-time chat, game rooms, player profiles that can be used by other games. These services are very common among modern online multiplayer games and we need a reliable and scalable alternative that uses a web3 tech stack. So, we have decided to create a game that incorporates all these features.
Blockchain smart contracts development is complete. I need help in backend and frontend development. You don't need to have any experience in Blockchain.
Tech Stack: Express.js + React.js + IPFS + Solidity
Current Team Size: 1
URL: https://github.com/cryptomafias/...
Note: We are eligible for a grant from the protocol labs - the company behind IPFS.8 -
Recently I’ve been super interested in learning more about blockchain and ethereum.
Anybody got any good beginner resources or projects? I like doing projects w new technologies bc I learn a lot better by doing. Thanks! -
I'm a computer science student and I'm looking to start learning blockchain. I think its applications have a lot of uses and that it has potential in the future. Can you guys tell me some resources which would help me start out with it?10
-
I'm starting to learn Solidity, and explore about smart contracts.
Anyone have a nice resource for learning?7 -
I have a doubt regarding blockchain. I understand how it works, but couldnot make use of it.
I am currently working on a platform which let client to assign task to their employee
Now I am planning to make use of blockchain on existing platform, to somehow set up a mechanism to authenticate that employee had completed the task, as a certification to the employee. I just cannot figure out how
I thought of an implementation, ( if its possible ) where client will trigger the smart contract with some employee-specific data, and the smart contract will generate a custom token, which will then be sent to the employee's account. This token will be non transferable1 -
Today I thought of an ethereum pun while deploying a smart contract to the testnet:
'I was trying to send some money to a buddy of mine on Ethereum, but it didn't work, cuz the network told me there was no wei' -
Few years ago, I started my journey on Ethereum development. I discovered an amazing and very promising ecosystem that is placing the foundation stones of the future of the internet as we know it.
So today, I decided to write a 'getting started' article as an introduction to some of the more obscure concepts.

EY and ConsenSys announced the formation of the Baseline Protocol with Microsoft which is an open source initiative that combines cryptography, messaging and blockchain to deliver secure and private business processes at low cost via the public Ethereum Mainnet. The protocol will enable confidential and complex collaboration between enterprises without leaving any sensitive data on-chain. The work will be governed by the Ethereum-Oasis Project.
Past approaches to blockchain technology have had difficulty meeting the highest standards of privacy, security and performance required by corporate IT departments. Overcoming these issues is the goal of the Baseline Protocol.
John Wolpert, ConsenSys’ Group Executive for Enterprise Mainnet added, “A lot of people think of blockchains as the place to record transactions. But what if we thought of the Mainnet as middleware? This approach takes advantage of what the Mainnet is good at while avoiding what it’s not good at.”
