Well that was a fun call I just had.
Owner of the company I freelance for: Hey I forgot to tell you something.
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.23

The best time to buy bitcoin was when it was released
The second best time was a few years ago when it was only like $200/btc
The third best time was probably last year before they went up 650% in value
The worst time is apparently whenever I buy in10
You think a junior dev pushing his code onto a production server is bad? Wait till you have that admin who is illegally mining Bitcoin on your production server. 😂
I went for a Cyber Security conference today with one of managers and this was one of the life experiences some of the speakers shared.18

The ultimate "I am vegan" guy will be arch linux user, vegan, trans, crossfitter and cryptocurrency investor. I've just met guy like this in my job. He did not shut up for a while. I am not sure whats he doing and whats his job but my guess is that hes paid for spreading cancer, sucidal toughts and eatig your will to live and talk with people...
R - retard
M - me
R: Hey CopyPasteCode I found this bug, it does 'this' insted of 'this'. *spreads arms to see his "muscles"*
M: *headphones off* Ok, I will look into it... *headphones back on*
R: Btw you invested something in the crypto, didnt you? Ive invested... ...bitcoin... ...crypto... ...litecoin..., do you think that... ...something... ...bla bla bla?
M: *tries not to kill myself after his 5 minutes of monolog* Ye sure
R: By the way Ive found this awesome vegan restaurant that accepts litecoin, would you like to come sometime?
M: *10 minutes monolog about vegan food and shit. At this point I want to die* Ok, I will now work on that back, see you later.
R: ye sure bro (wtf, "bro"?)... *looks like hes walking away* *teleports on my otger side touching my monitor*
WOW you are also a Limux user? 😮 Ivr installed arch linux this weekand and its so awesome, *another 6 minutes of monolog*
M: *smiling and preparing to kill him or myself* Nice, awesome *fake smile*
R: Anyway, I gotta go (FINALLY!!!), btw, I am going to the *name of local trans and gay club*, wanna go with me?
M: *after a month after a breakup with my GF (because she was cheating on me) which everyone in the office knew...)* Not really *trying to thing how to say "fuck off" without having meeting with HR*, I cant, I already have somethimg.
R: Oh, ok. Btw, you are rly cool bro (again), we should hang. We should hangout more often...
I hope someone is paying me for loosing 27 minutes with this guy.14
"So... what about Bitcoins, huh?"

Adylkuzz "saves" users from WannaCry
In fact, because Adylkuzz(malware that mine cryptocurrency) had infected many vulnerable machines long before WannaCry and shut down their SMB port, the malware might have accidentally saved many potential victims from having their data encrypted by WannaCry.1
So I host a few mining pools and some of the stories we hear from miners can be quite interesting. One of our miners recently had his front door busted off the hinges and a drug bust team go into his house and turn the house upside down. How did they determine that he was a threat for growing illegal drugs? Well he had a high power bill because of the miners and he grows flowers and food inside of his house and that was enough for THE NYPD to get a warrant.
Now he is responsible for cleaning up the mess the police made. What scares me the most is that they are tracking soil you buy online along with high power bills. What the hell USA im a proud Canadian9
Why do so many people waste their time and their computers turning coal into heat? It really pisses me off.
Often I meet smart guys who are fairly decent coders and after what starts as an interesting conversation is instantly destroyed by cryptocurrency.
It is *exactly* like enjoying a discussion of the intriguing nuances of quantum chemistry only to have the guy say, "thats all cool, but how do you make meth?"
You want to use your decked out rig to make money? Fine. But please help us solve important problems instead of literally wasting electricity. Just google search "supercomputer physics" and you will find a thousand current problems requiring extremely fast computers for number crunching. All of them can make you more money than crypto and all of them help society at the same time.
We burn coal to make most of the electricity on this planet. Most coal stations burn around 20,000 tons of coal per day. The world burns about 250 tons of coal every *second*. This is converted into carbon dioxide. (coal = carbon, add two oxygens when you burn it, producing three times as much mass in CO2, which then goes out the smoke stack)
The big picture is this: currently we are forced to burn coal to make the world work. Turning off the boilers would result in an almost instant apocalyptic collapse of society. BUT, we don't need to burn it merely to produce waste heat in your video card array.
Please use your superpowers for good.

Have you heard that Facebook is developing a cryptocurrency?
Huge waste of money. Everyone knows Facebooks security flaws and will problably not invest in their cryptocurrency because of that.16
Recenty I have studied a lot about Bitcoin and Blockchain. The technology behind these things is amazing. And people are going mad over it. But, are we really going to the right direction? I have doubts.
Bitcoin was targeted to be a decentralized system. But in the present scenario, if BTC.com, AntPool and ViaBtc somehow merge, they will own more than 51% of the total computational power of the Bitcoin network. And if that happens, they will have full control over the whole network and will be able to replace the whole Bitcoin Blockchain with their forged entries if they want. By the way, btc.com is China based and owns 29.6% of the total computational power of the Bitcoin mining network. Forget about merging, if btc.com grows independently, who can assure that they would never cross the 51% threshold? Same problem exists with other Blockchain systems too. Are these systems really decentralized as they advertise? I really doubt now.8
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.7

Whats everyone's thoughts on coin miners running in the background of a website as an alternative to adverts?8
So now you can hire a container with computers and all that stuff so you can start mining crypto currency immediately... What is humanity going to be in 10 years? Everyone's just gonna mine Bitcoins instead of working? 😦6
If cryptocurrency is banned and revoked from the internet, in what other way would ransomwares ask their victim to pay?14
Well... Well... What a multi-talented personality...
Every connection I see on LinkedIn has these buzz words in their tag line: AI/ML, Cryptocurrency, Blockchain.
This guy even has Smart City...!!!
Don't know how many of them are legit... I just don't understand each of these techs are so vast... Still people manage to get expert in all of them in just few days... What's the secret...?8
So I and my friend worked on a website for a guy about 6 months ago and he didn't payed us (we had a contract but he is a d##k). Whenever we use to ask for money he'd ask us to do something else or add another stuff on the website (told you d##k). So we decided to leave without taking the money and now he's still using the website that we made.
While working with him he shared his server credentials and they are still the same (we still have access to everything).
Now we were thinking to teach him a lesson, we don't want our money back.
So, devranters what's the evilest idea you can come up with?
So far my friends suggested me:
-replacing websites homepage with some abusive content
-delete everything on the server
-revoke his access to server (he would somehow get that)19
Got an older GPU (Asus EN8600GT) and already have cause for it.
Let's get mining some cryptocurrency :)))))7
So uh... your computer might be being used for bitcoin mining, and you might not even know it. How do you feel about this? Do you consider the site freeloading off your computer's processing power?10
This type of post might be good for a weekly rant (if it has not been done yet) "Most Bizarre bug"
So I am working with laravel and vuejs and I use phpstorm as my IDE and today I had the MOST bizarre bug. I'm working on a cryptocurrency website and I'm making a vue component that is going to be a stratum generator for miners and I wanted to make it a component in vue so it can be used anywhere in the site. So I wanted to call the component "StratumGenerator.vue" and i didnt think that this would be an issue. Oh boy was I wrong. So immediately my syntax highlighting did not work nor did emmet autocomplete which is something I can't work without. So i go on for about an hour to fucking figure out how to fix jetbrains vuejs syntax plugins and a very long story short it was because THE FUCKING NAME WAS "StratumGenerator.vue" LITERALLY ANY OTHER NAME WORKS
I've checked its not a blacklisted keyword Stratum and Generator work fine on there own its also not a length thing so right now I have not a fucking clue on why it does not work but i'm glad I figured out.8
If you ever thought hell didn't exist...
I just spent the day explaining cryptocurrencies to a room of social sciences and law students.
I really need to get drunk, but it's only Thursday 😫5
I noticed the main dogecoin repo was one star short of a significant milestone. Is it odd to feel honoured to be their 2000th?1
Just found out that the cryptocurrency trading company I'm interning at doesn't even have an order matching system.4
yay or nay?
for who are wondering what is on the screen :
i am working on a fish tank simulator gamr, which every fish have different unique combination and/or permutation. i combined this with cryptocurrency, the idea is similar to CryptoKitties and Insaniquarium combined. the implementation is not yet done, but currently i am working on the in-game market front-end functionality.
sorry no in-game preview/screenshot yet :P
curently thinking about considering to open source it and a collab.52

My fucking router didn't yet get patched, my fucking phone is outdated and I can't change to my patched one because devrant just shits the bed in extended desktop mode. Windows 8.1 loses support in 3 months, rendering my last chance of using it on my surface pro done, making me use windows 10 with its fucking shit ass not optimized tablet interface. I have just fucking constant paranoia what else could be hacked tomorrow, nothing is fucking safe anymore for fucks sake. I even went as far as implement 3 step auth and intrusion detection on my shitty ass VPS nodes, fucking give me a break you fucking assholes.5
In 2018 everyone wanted to be in crypto. In 2019, we will find out who really wants to be in crypto. 💸💸💰19
WARNING: I am a n00b at this crypto shit!
I've decided I might dable in cryptocurrency mining for a little and see what comes of it but have no clue how to start... Can someone point me in the direction of anything that could be helpful?27
First: happy birthday, devRant.
Second: the more I use it, the more I would like to see implemented as a block-chain, a la Steemit
Ok so I have done some work with crypto currency mining pools and recently a client requested for me to make a splash page that showed data from multiple instances of these pools APIs. I went to find some documentation for this open source api and to my surprise there is none. I thought of querying the public API from the clients side and it worked, however it's so slow that the data shows up roughly 20 seconds after the page loads.
Easy fix right? Make a PHP server get the data every 5 seconds, cache it and serve the data with the page and use a websocket for live updates! Until I found out that there is no practical way in this garbage framework to get the damn API data without making an HTTP request or mutilating the original source code. I'm so done with this garbage framework. It literally loads pages based on a page and action parameter on the index.php. I quit.1
They actually support me.
My mother, grandfather and grandmother think I'm a highly skilled mage.
My father, who thought me how to use torrent, sees my potential and wants me to become a developer in his company.
I explained him the basic concepts of Bitcoin, block chain and AI and thinks. He wants me to create a cryptocurrency 😮😃.
All the more reason to invested into cryptocurrencies (pun intended).
Anyone else feels technology didn't have a major turning point in a while?
I mean, since the late 1980's we had an explosion of technologies:
World Wide Web
But now? It seems like stagnation for the past 5-10 years or so.
Sure here and there there some nice stuff(like Cryptocurrency, Cloud services, IoT), but nothing that feels completely game-changing.
What do you think will be the next thing that will completely change our lives?18
A few days ago our server was compromised due to an outdated Jenkins version. The malicious user installed a crypto miner on the server... The same day that it was found I told management that I'm interested in helping out with the server. Since then, nothing happened... No updates, no security measures, no nothing (except for the removed crypto miner and updated Jenkins software)
Oh well only a matter of time before another hack...
Question to some (who work way way way longer than me) med - seniors, should I make a big deal out of this? And keep pressure on it. Or should I just leave it be and wait for the next comprised server? I know devrant is not a Q&A service, but some dev to dev advice is much appreciated.
My father is very interested in stocks and thus he has also heard of crypto currencies. He just asked me if I could setup a Bitcoin wallet and if I know more stuff about crypto currencies.
I myself know a bit about these things so any tips for starters? 😄2
Which will block browser coin miners on Chrome for now. Other ad/script blockers might work (though not always guaranteed).
Currently, these miners don't limit their CPU usage (and neither does the browser) so it's not great for your PC use.
If implemented correctly, like only using for a few seconds or for captchas/link shorteners (as suggested on the Coin Hive site), this could be a nice alternative to ads. But there is a guarantee that many will start using this unethically and not even tell users, nevermind that they'll do it for the entire session of the site.
Add Service Workers to the mix and it's a bag of trouble.12
When you need just simple plugin for the browser and what you get is a crypto miner fully utilizing single core :(2
What are folks thoughts on this?
It’s basically an mturk model that pays out etherium to python coders.
Im skeptical about
1. Cryptocurrency payment for work, I don’t know enough about crypto to trust it’s use as payment?
2. Payment for open-source work: on one hand, i support workers getting paid for their work, BUT (imo) the coolest part of open source is that it’s one of the few environments where people work for the works sake, not for $$.
I had a bigger list but it left my brain as I was typing, so what do y’all think?3
Oh, me? I am so excited about all the computing power that's gonna be stolen from people who had updated their Intel CPUs last month.
I dunno what they're up to but I'm sure it's very exciting. I'm lost between Skynet and a one world government cryptocurrency mining they will use the power for.
What do you think?3
Any new cryptocurrency or blockchain network usually has a better front-end UI than its white paper.

P.S. I stole this pic from the internet6
I found this in a restaurant bathroom. First time ever seeing something like this advertised offline. Pretty cool, eh?
Ps. No face reveal for you.1
Hey, here's an idea. Ethical cryptocurrency mining Adblock.
We've been talking a lot about mining as a revenue source and its ethics here, so that gave me an idea.
I've seen a lot of talk about blocking or boycotting mining websites.
Adblock has the "ethical ads" thing to allow reasonable ads to be displayed.
What if we made the mining equivalent of that: an extension that the user allows to mine with x resources, that prevents websites from doing their own mining, but which redistributes its mining results.
The website could just add a bit of script to tell the extension who they are, and while the page is on the foreground or streaming content, the extension would mine on their behalf.
This could also allow more transparency for the user: "your computer has generated x money for website y".
Wouldn't that be a nice middle ground? Does anyone know of a project like that?9
Did you notice these cryptocurrency thefts are nowadays called "Coin hacks", not "Bank heists"? Funny.2
I have course in university where I have to learn how bitcoin works and stuff.
Now you might say these concepts done there are "interesting". But when seen completely rational and compared to existing concepts, also invented after 1990... This is plain bullshit.2
It's ironic to see recruiters in linkedin who criticize bitcoin end up looking for blockchain developers.1
Decided to spend more time on LinkedIn to familiarise myself and start looking for potential employment opportunities.
For past month or so, I've seen few decent opportunities, which is a nice start. However, for every decent post, I've come across:
- About a hundred of posts by self-proclaimed crypto experts who spout absolute gibberish and somehow get thousands of likes. 5 min google search and absolute minimum knowledge of economic theory discards 99% of their claims and statements
- Handful of idiotic "career advice" blog posts
- Numerous posts, both bashing and helplessly supporting shitty recruiter practices
- more crypto nonsense
- People jerking themselves off for running a profitable business (company launched a 1-5months ago)
Really starting to hate the platform, seems like all the integrity it had before becoming fully mainstream, has gone down the drain and it's become a straight up corporate circle jerk1
Got in a somewhat heated discussion earlier a'd wanted to get some more input...
Friend of mine has a community site for a game, and is running adds to pay for the hosting costs etc... He however has recently changed adds provider and now they've become more profitable but also a lot more obtrusive...
I suggested perhaps looking into getting something like coinhive, mining monero coins with your users browsers... He was really averse to it, but I think that it can be viable alternative to adds, as long as you allow your users to not participate and don't go all out with their processors but throttle it to say 5% orso...
Anyhow, he wouldn't have it, and I was wondering if I was alone in thinking I'd rather have some coins mined using my processor than seeing adds, especially if it's not at full speed, and with consent (and not on mobile)5
I don’t want to come across as entitled, but what kind of person gets a software internship in California?
I go to university in California, I’m a junior CS student, I have 8 public ios apps (2 charted in US, 1 acquired small sum [5k]), I completely designed the blockchain parameters and built multiple front-end apps for a new cryptocurrency (it hit 3mil$ market cap).
And I applied to 22 tech companies. Rejected from pretty much all (waiting on my dream company still). Do they just not even get to some applications or do I literally have to be superhuman?5
He is not really my coworker, but this seems like perfect opportunity to rant about this.
So, there is this guy, who asked me whether I want to join him in a project. I asked him what kind of project and what would each of us do. The project was Cryptocurrency Arbitrage and I would code the bot to do the stuff and he would design the logic to even out the money after the transfer. And we would get two thirds of the money and I would get the rest. I haven't said no yet, but ...
Do you know what other kind of money is created in a way that makes it nearly impossible to forge, is typically untraceable, and is digitally transferrable, but doesn't normally fluctuate in value by 80% in a year? Fiat money backed by national governments. Cryptocurrency is very cool but as long as it isn't managed like a real currency, it won't be safe to hold long term for anything other than speculation. And the usual "what if shit happens" argument doesn't apply because in a real, large scale emergency, ethereal things that can only be accessed on electronics get you less in exchange than paper money.4
The internet allowed for people to never have to go to a library for knowledge.
Bitcoin allows for people to never have to go to a bank for money.14
How would you guys feel if your favorite app gave you 3 monetization options.
Crypto Mining at max 70% load
Giving you 100% privacy.
Ads, rip privacy, rip cpu.
Paid content /micro transactions
Rip wallet , some privacy concerns, happy cpu.
So I just heard that Bitcoins are illegal in my country. Like WTF? This is outrageous! Are you that much of a control freak that you couldn't allow a cryptocurrency to run, government? You and your taxes and shits!!! Ughhhh!
On another note, the cryptocurrency is indeed growing its boundaries. What are your opinions on it? Do you think maybe one day it will replace all conventional form of currency as we know it today? If yes, how long will it take?6
"I don't have time to talk about the blockchain but we can HASH the details later"
Me and my friends were thinking about making a cryptocurreny for college project.
And we don't know where to start.
Could I get some help?7
The college's Dean of Projects, when evaluating my first year project, which was using blockchains.
DoP: "So, we have this cool cloud system, incase you need to mine or something, come contact me and I'll give you access."
ME: "Sir, this project is distributed and uses computers in a network to protect data, it is not cryptocurrency."
DoP: "Yes, I understand, but we have this system here that can mine a lot, I overheard one of my staff talk about how we were wasting money by not using the system to do such stuff."
ME: "Sure, I'll have it setup to mine some altcoin then."
DoP: "Yeah, well I don't know anything about this stuff, can you do it all, yourself. I'll give you Admin access"
ME AFTER GETTING ADMIN ACCESS
"HOLLY F#@%*! Now I know where these sites are hosted!"
NOTE: I know that every other college has this problem, but the staff is the least innocent.
Someone managed to install a virus on my class' computer. It's called amazon assistant or something like that and it keeps in opening a blank window called aa.hta as soon as you close it it opens again. It didn't change any file so idk, the only assumption i can make is that it mines cryptocurrency. But whatever is fun watching my teachers trying to close it.3
Anyone in crypto mining?
Have a small question: why the fuck I am payed half of what I was expecting?!
I know the estimation is not accurate, but half of that or less?!?
(Estimation from the H/s)3
In todays lecture my professor told us that our city is planning to do its own cryptocurrency. Why does everyone do stuff just because it's a hype?1
What do you think about onecoin/ onelife? Have you heard of it? They offer pretty good deal, but is it worth the money?7
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
After reading many articles and watching YouTube videos on Blockchain, how it works, the new framework etc etc. It's evident that blockchain can be used to eliminate many problem faced in different industries and so on. What I cannot seem to find is a perfect application of solution to these problems in real life. I know it's too early to speculate, but thinking of all the internal(or under the table money) transactions happening, what is the possibility of mass adoption of blockchain given these conditions.3
Hey ranters does anyone know the best way to learn crypto currency. Its a very challenging topic for me5
For this week, there is this student from a high school who's joining my company to complete his job experience project for his school.
Since my company is on the cryptocurrency trading and programming side, I'm not sure what kind of task is suitable for him, and I'm afraid that some tasks might be too difficult for him.
He did mention he was interested in programming and he knows how to use HTML and CSS ( yes I know these aren't really programming languages ).
Any suggestions or ideas on what tasks to give him or teach him?6

Running a mid size Cryptocurrency mining farm and calling yourself as an entrepreneur? #JustAsking7
I have to Select my Bachelor thesis/topic in the next few days. I would like to do something with Crypto Currencies especially with the Blockchain System. There is a wide range of usage for that and i Think it could be very interesting.
The Problem is that am Not Really Sure what Topic or challenge my Project could contain. There is much to say about it but i dont Think it would be enough to just describe it.
There should be a Problem or anything like that I can solve..
Or Is it possible to just Analyse the blockchain and the affect it have These Days and the Future?
I would appreciate a few ideas or suggestions :)
