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 in11 -
Dear Telegram, the fact that you're using a service which provides app usage/metrics/analytics kind of is not nice.
"But they've got the right to!"
Of course they do. But, when you advertise yourself as a messaging app focused on privacy, I expect you to behave that way.
And yes, we know your crypto is broken as fuck but that's not the point right now.
Oh and yeah, the next blog item will probably be about Telegram and how not-privacy friendly it is.22 -
It's funny to see how a coworker of mine and me are very similar minded on some privacy stuff. He's a very cool/open guy and just a regular consumer (used the default services etc) but he shares quite some of my views. This is a convo we had today:
*got to the WhatsApp subject somehow*
Him: oh right, you didn't use that haha
Me: yeah 😅
Him: why was that again, privacy reasons or something, right? xD
Me: uhm yes *help*
Him: Well fair enough.
Me: so you'd think I'm right? I mean it uses end to end crypto... (I'm entirely with him in the next few lines but I always approach it carefully)
Him: they veeeery probably have some kinda fucking masterkey.
Me: why'd you think that?
Him: it has over a billion users, the owner is facebook, fb is directly integrated with several mass surveillance programs, they are known to work closely with one particular one, the intelligence interests are way too high for letting such an opportunity pass and after all, THE FUCKER IS CLOSED SOURCE AKA NO ONE CAN FUCKING VERIFY THE CRYPTO NOR THE APP ITSELF.
Me: I agree haha 😅
Him: it's not rocket science, it's modern day mass tracking/surveillance logic :)
I like that guy.5 -
So today (or a day ago or whatever), Pavel Durov attacked Signal by saying that he wouldn't be surprised if a backdoor would be discovered in Signal because it's partially funded by the US government (or, some part of the us govt).
Let's break down why this is utter bullshit.
First, he wouldn't be surprised if a backdoor would be discovered 'within 5 years from now'.
- Teeny tiny little detail: THE FUCKING APP IS OPEN SOURCE. So yeah sure, go look through the code! Good idea! You might actually learn something from it as your own crypto seems to be broken! (for the record, I never said anything about telegram not being open source as it is)
sources:
http://cryptofails.com/post/...
http://theregister.co.uk/2015/11/...
https://security.stackexchange.com/...
- The server side code is closed (of signal and telegram both). Well, if your app is open source, enrolled with one of the strongest cryptographic protocols in the world and has been audited, then even if the server gets compromised, the hackers are still nowhere.
- Metadata. Signal saves the following and ONLY the following: timestamp of registration, timestamp of the last connection with the server (both rounded to the day so not on the second), your phone number and your contact details (if you authorize it) (only phone numbers) in HASHED (BCrypt I thought?) format.
There have been multiple telegram metadata leaks and it's pretty known that it saves way more than neccesary.
So, before you start judging an app which is open, uses one of the best crypto protocols in the world while you use your own homegrown horribly insecure protocol AND actually tries its best to save the least possible, maybe try to fix your own shit!
*gets ready for heavy criticism*20 -
Oh fuck and boy Jesus, how on earth is this still a thing 😦
MD fucking 5 is not a fucking “secure” crypto algorithm.
This site has 14 million breached accounts with fucking MD5 hashes.
I think I’ve had to much internet for today.

Following a conversation with a fellow devRanter this came to my mind ago, happened a year or two ago I think.
Was searching for an online note taking app which also provided open source end to end encryption.
After searching for a while I found something that looked alright (do not remember the URL/site too badly). They used pretty good open source JS crypto libraries so it seemed very good!
Then I noticed that the site itself did NOT ran SSL (putting the https:// in front of the site name resulted in site not found or something similar).
Went to the Q/A section because that's really weird.
Saw the answer to that question:
"Since the notes are end to end encrypted client side anyways, we don't see the point in adding SSL. It's secure enough this way".
😵
I emailed them right away explaing that any party inbetween their server(s) and the browser could do anything with the request (includingt the cryptographic JS code) so they should start going onto SSL very very fast.
Too badly I never received a reply.
People, if you ever work with client side crypto, ALWAYS use SSL. Also with valid certs!
The NSA for example has this thing known as the 'Quantum Insert' attack which they can deploy worldwide which basically is an attack where they detect requests being made to servers and reply quickly with their own version of that code which is very probably backdoored.
This attack cannot be performed if you use SSL! (of course only if they don't have your private keys but lets assume that for now)
Luckily Fox-IT (formerly Dutch cyber security company) wrote a Snort (Intrustion Detection System) module for detecting this attack.
Anyways, Always use SSL if you do anything at all with crypto/sensitive data! Actually, always use it but at the very LEAST really do it when you process the mentioned above!31 -
What I'm posting here is my 'manifesto'/the things I stand for. You may like it, you may hate it, you may comment but this is what I stand for.
What are the basic principles of life? one of them is sharing, so why stop at software/computers?
I think we should share our software, make it better together and don't put restrictions onto it. Everyone should be able to contribute their part and we should make it better together. Of course, we have to make money but I think that there is a very good way in making money through OSS.
Next to that, since the Snowden releases from 2013, it has come clear that the NSA (and other intelligence agencies) will try everything to get into anyone's messages, devices, systems and so on. That's simply NOT okay.
Our devices should be OUR devices. No agency should be allowed to warrantless bypass our systems/messages security/encryptions for the sake of whatever 'national security' bullshit. Even a former NSA semi-director traveled to the UK to oppose mass surveillance/mass govt. hacking because he, himself, said that it doesn't work.
We should be able to communicate freely without spying. Without the feeling that we are being watched. Too badly, the intelligence agencies of today do not want us to do this and this is why mass surveillance/gag orders (companies having to reveal their users' information without being allowed to alert their users about this) are in place but I think that this is absolutely wrong. When we use end to end encrypted communications, we simply defend ourselves against this non-ethical form of spying.
I'm a heavy Signal (and since a few days also Riot.IM (matrix protocol) (Riot.IM with end to end crypto enabled)), Tutanota (encrypted email) and Linux user because I believe that only those measures (open source, reliable crypto) will protect against all the mass spying we face today.
The applications/services I strongly oppose are stuff like WhatsApp (yes, encryted messages but the metadata is readily available and it's closed source), skype, gmail, outlook and so on and on and on.
I think that we should OWN our OWN data, communications, browsing stuffs, operating systems, softwares and so on.
This was my rant.17 -

The company i work for has a jenkins server (for people that don't know jenkins, it's an automated build service that gets the latest git updates, pulls them and then builds, tests and deploys it)
Because it builds the software, people were scared to update it so we were running version 1.x for a long time, even when an exploit was found... Ooh boy did they learn from that...
The jenkins server had a hidden crypto miner running for about 5 days...
I don't know why we don't have detectors for that stuff... (like cpu load being high for 15 minutes)
I even tried to strengthen our security... You know basic stuff LIKE NOT SAVING PASSWORDS TO A GOOGLE SPREADSHEET! 😠
But they shoved it asside because they didn't have time... I tried multiple times but in the end i just gave up...13 -
My next project is creating a genetic algorithm that can play with crypto currencies for me.
I shouldn't have told my family. They think i'm going to be sharing the money now 🙃3 -
Downloaded Kubuntu because i couldn't seen to be able to boot from a freshly created KDE Neon bootable usb.
Installed it onto my netbook (Lenovo Thinkpad X121E) and it worked great!
But just the fact that somehow the installer froze when trying to setup hdd encryption kept bugging me.
Took a random flash drive which was laying around and put it in to see what would happen. KDE Neon booted just like this and everything worked very well with hdd encryption.
I now have a very secure netbook 😊15 -
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 -
Would the web be better off, if there was zero frontend scripting? There would be HTML5 video/audio, but zero client side JS.
Browsers wouldn't understand script tags, they wouldn't have javascript engines, and they wouldn't have to worry about new standards and deprecations.
Browsers would be MUCH more secure, and use way less memory and CPU resources.
What would we really be missing?
If you build less bloated pages, you would not really need ajax calls, page reloads would be cheap. Animated menus do not add anything functionally, and could be done using css as well. Complicated webapps... well maybe those should just be desktop/mobile apps.
Pages would contain less annoying elements, no tracking or crypto mining scripts, no mouse tracking, no exploitative spam alerts.
Why don't we just deprecate JS in the browser, completely?
I think it would be worth it.22 -
Trash, trash, trash.
Who the fuck writes this shit?
Who the fuck lets these trash should-be-junior devs roll their own crypto? and then approves it?
The garbage heap of a feature (signing for all apis) doesn't follow Ruby standards, doesn't follow codebase conventions, has `// this is bridge` style comments (and no documentation), and it requires consumer devs to do unnecessary work to integrate it, and on top of all this: it leaks end-user data. on all apis. in plaintext.

Had a final year project defence today in university. There were about 15 CS teachers in the room.
Our project was "Crypto Currency". After all the presentation was finish.
Teachers: so what is this blockchain?
** explained all about it and how it works with marker in a whiteboard **
While most of the projects were rejected and they have asked several cross questions to other friends, they didnt even ask any question to us and said our project is accepted.
Turns out teachers were taught by a student today, feels so good 😎 😂4 -

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 Canadian8 -

There's this TV show called Startup. The protagonist "hacker" tells a guy to go learn JavaScript. And then they show him learning Java. If noobs make this mistake, I get it. But a TV show that's featuring a "hacker" who can create crypto currency and dark web sites? WTF?

Hackathon rant.
So I had my first hackathon ever.
It was about co2 reduction which is pretty neat but our team leader had a different view on this. He only saw money in his idea so we build a smart energy meter that advised the user on how he should control his energy. And if the user had solarpanels or something his overtake of energy would be converted into a crypto currency and transferred by our Blockchain system.
The idea is pretty cool but it had no real co2 reduction and way too customer based. Which kinda sucked for my first hackathon but our business guy gave a amazing overwhelming pitch about stuff we didn't make at all. And somehow we ended up on the third place yay

Interesting fact: Dogecoin is popular because of a Reddit bot that stole everyone's money.
DogeTipBot, a Reddit bot that was designed as a 3rd party resource for tipping Reddit users for good content was a bot that used Dogecoin as a micro-tipping service, giving many users their first crypto experience and popularizing the coin.
The creator of DogeTipBot went bankrupt, sold all of his coins, AND all of the coins of his users, and shut down the bot.
A currency born as a joke, made intentionally as backwards as possible, and popularized by a scam, is now worth $50 billion USD... now that's a meme.18 -

I don’t have a real way to find a good company.
As a rule of thumb I avoid startups.
This doesn’t mean all new young tech companies are bad. I avoid the startup rethorics. Those are 🚩 for both new and old companies.
And I avoid crypto, nft and other scam businesses. There’s an high chance that the owners will run away with the money and leave you without a job.6 -
Ok fellow ranters. I've scoured the internet for hilarious and enraging stories of programmers being asked to either work for free, or for stock options, or to hack (crack) stuff, etc.
Here's my latest one. A friend who's obsessed with crypto came up with a "great" idea which was for me (of course) to build a landing page for a fake company to trick people into submitting their crypto wallet keys and all that. What started as a joke quickly turned into my friend getting mad at me for not wanting to actually make it lol. Like seriously wtf is with people. All the reasons not to do that scheme are plainly obvious!
Next. Some person who worked for a company I consult with pulled the generic. "I have this great app idea" line & proceeded to of course ask me to "not steal it" lol. It was just an app that would list gluten free restaurants... That's hardly even an idea!!
But what's fucked up about all this is my friend from the first story is so obsessed with becoming a "crypto millionaire" he actually resents me now for not
1. being obsessed with crypto
2. not committing cybercrime on his behalf
Anybody else have enraging stories about stuff people have asked you to do?3 -
Okay, fuck it. I'm going to buy $20 worth of every penny crypto currency until one of them explodes making me a millionaire
This is big brain time9 -

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 -
I got a kindle paper as a hand me down gift. And I feel I'm reading so much more than before, now!
I'm starting a new small novel
A Wrinkle in Time, I'll be reading alongside my girlfriend.
I'm 52% done with a book called
Python Tricks: The Book
Literally coolest book I've touched. Contains a bunch of different tidbits about the language, granted most of them confirmed my understanding, but it's still neat to read and learn about them in a more rigorous setting.
I'm 13% done with another book called
How to Day Trade for a Living
I'm heading for the crypto currency exchange, but with a catch,
I'm reading another book called
Genetic Algorithms with Python
You can probably already guess where I'm heading.
I feel armed with more knowledge and I feel like this is a really great way to start the New Year off.8 -
I feel like I've ranted this before. many times. but here we go again because Australia.
why do people think you can just ban math? like really?! that's what crypto laws do. they require companies to use shitty math. and what prevents me from using the good math? nothing! oh I mean... I won't use it? scouts honor.
you can't ban math.
literally billions of internet users don't fall in your jurisdiction.
no single jurisdiction can cover more than a subset of the internet.
I will use whatever maths I damn well please.
fuck off. please stop making us less safe.

That's not how this works. THAT'S NOT HOW ANY OF THIS WORKS REEEEEEEEEEE!!!!!!

Recently at my work everyone got all hyped about blockchain. I've spent years studying it and especially crypto so I like to think I know a lot about it. Now every time some feature is discussed (like tracking video views) someone non tech shouts out "Oh we can use a blockchain!" And I have to spend half an hour convincing them why it's a bad idea in this particular case. Like we don't need to share that data, we don't need to ensure integrity without trust etc. I mean a blockchain is a great piece of tech but please stop trying to apply it everywhere...
It's like people think that the blockchain features at its most simplified level don't work anywhere else. E.g. as if stuff you put into MySQL suddenly changes because data integrity is not a 'feature' in that sense...2 -
I got scammed for $600.
Its not the scam that pissed me off. Its my ego as an engineer that blinded me.
It was last year during crypto nft ups and downs.
Its called a frontrunner scam.
From what I remember, I followed this tutorial on YouTube to setup this bot on remix ethereum compiler.
I read all the code and couldn't find anything fishy.
So I figured, all the comments are hyping it, fuk it, $600. Let's see how it goes, I can take out my money if it flops.
And this fuking contract wouldn't show any updates on Etherscan
The guy in the video mentioned you may need to wait a while.
Plus he sounded like an honest guy.
I googled it after I fuking put my money in and followed the tutorial.
And a video explains the scam.
Theres a file filled with comments to throw you off. But hidden in the comments is some code to change the wallet the crypto goes to.
Fuking wrekt. Rookie mistake.
I went to the hackers telegram group and told them I'd report them, he said you gota put in more money for it to work.
Realized I'm being trolled, I rage quit and never told a soul.10 -

Fuck, I'll always be a noob. Knowing next to nothing about software development, hacking, exploits - just anything.
Felt a bit proud to had reached the level "hacker" on hack the box. Was fun solving stego, crypto and reversing challenges, diving into assembly the first time. Felt cool stepping through a disassemblied executable with radare, and understanding what a NOP slide is...
However all the illusion crumbled down, when I watched this CCC talk on OpenBSD security, where the speaker was underwhelmed with one of OpenBSD mitigations, where they tried to disallow them: "NOP slides?! Srly? No one is using that anymore. Just look at current exploits."
I felt so stupid, which I probably am. Will never catch up with those guys.
But whatever. In the end we all know nothing. We have no clue, but some are more apt in disguising it behind big speech.
(really like this German song: https://youtube.com/watch/...
Those lines always give me a chuckle:
"Man has no idea.
The house has no idea.
The tree has no idea.

I just saw Kickstarter's blog post about moving over to the Blockchain. They're doing it because, uh, protocols, or something. No joke, here's a direct quote from their post:
"You may have heard of HTTP (Hypertext Transfer Protocol) which helps you browse the web, or SMTP (Simple Mail Transfer Protocol) which helps you send email. Protocols like these make up the unseen infrastructure of the internet. Imagine that, but for crowdfunding creative projects."
What the fuck does that even mean? The rest of the blog post is more of the same. They packed it full of every crypto buzzword they could find while also not actually providing any useful information.

I work as a freelancer and one time I had a client that needed some work done on a crypto website. I was so hyped up because the money was good so I jumped on it. Fast forward 2 weeks later I still couldn’t figure what the shit I was doing as the client kept asking for update.
Yes, I have experience with blockchain but my skill on Javascript just couldn’t help. I did google and also ask questions on S.O. but it wasn’t enough to get me on track.
At the end, I reached out to the client and apologized for not being able to meet up with their request and then recommended someone else.
So I’d say “I lost faith” on my skill as a Javascript dev at that moment for not being able to use some blockchain APIs effectively and also look forward to improving my catalog.2 -

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 -
WHAT THE FUCKING SHIT DO YOU WANT FROM ME??! I LITERALLY GET SPAM MAILS EVERY 5 MINUTES (i know I know, some of you get more than that) ABOUT BITCOIN.

I'm sitting here doing my stuff and every few minutes my phone starts ringing and I'm like "hey maybe person x answered or something else important happened" but when I actually look at it to see whats up it's just a fucking email about bitcoin being outdated and it tells me to maybe invest into other crypto currencies. After actually reading one of the spam mails because I was interested in what they actually want from me I had to find out that they do not even mention any other currency or website. WTF INTERNET??

The graphic cards supply is completely madness. Even after the crypto crash it is not possible to buy RTX cards at price any close to MSRP.

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...

Sorry if this is a bad read, pretty new to devRant and writing in general.
I can't help but think and think of how much I fucked up my opportunities to completely change my life/financial status a couple of times. Damn.
A few years back (it was 2009, I think) I was playing Diablo II online, helped some random guy get through the hard levels. Normally, in such situation the lower lvl player allowed the higher level guy to grab the valuable boss loot; however this time the guy except sharing the loot with me asked me if I want his spare 2000 bitcoin. I asked if it's of any value, he said "not really".
I said I'd contact him later, when I figure out how this thing works and how to setup a wallet.
Guess what, I was too lazy and forgot about this thing completely. Then we lost contact.
In 2010, I made a comeback to bitcoin, but instead of buying it, I downloaded the bitcoin client, the blockchain (it was 800 mb in size, I remember) and have been contributing by running it on my PC for like a year.
Finally decided to get it ~3 years ago. Bought 2.5 BTC for 400$.
Was holding it, until I fell for the "free OmniseGO" scam and somebody stole them off me.
All of these can't get out of my head.
I visit coinmarketcap literally every hour to see how much I could have now. My girlfriend, friends, family, all fail to cheer me up. I still made a pretty good deal buying 5.5 ETH for 45$ and thats like 2500$ soon, its nice but this much I can make by coding
Shit, what do I do to stop being stressed except for seeing a psychologist.
May my failure make you smile today4 -

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)

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 -
I really hate that smart people are the worst kind of cultists. This means that people who do some pretty cool and novel stuff fall for things like Musk-fanboyism, NFT and other crypto BS, or things like outright fascistoid ideas about "MSM"-conspiracies, race-ideology or IQ... And I hate it.

I'm not a big follower of Crypto Currencies at all and haven't become financially invested in anything really. I just love the way development works on a blockchain; it is quite interesting and It feels really fresh solving problems using code that will become immutable. -
devRanters beware! In-browser JavaScript crypto mining is becoming a thing.
https://coin-hive.com/
I found
https://chrome.google.com/webstore/...
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 -

Avoided IoT(IoS - InternetOfShit) for a long time now, due to the security concerns with retail products.
Now I looked into 433 Transceiver + Arduino solutions.. to build something myself, just for the lolz.
Theory:
Smallest Arduino I found has 32 KByte of programmable memory, a tiny tiny crypto library could take around 4 KBytes...
Set a symetric crypto key for each homebrewn device / sensor / etc, send the info and commands (with time of day as salt for example) encrypted between Server <-> IoT gadget, ciphertext would have checksum appended, magic and ciphertext length prepended.
Result:
Be safe from possible drive-by attacks, still have a somewhat reliable communication?!
Ofc passionate hackers would be still able to crack it, no doubt.

Users complain about advertising and how it is annoying to have to see these ads just around the page while they just want to see the main content. So what do they do? They decide to use adblockers which start pushing web admins to find another method to make money. So half the time they offer the service for a lot more than normal which makes people not want to pay for it. So now I decide to push into the embedded crypto miners, which sadly cut in half my earnings but it’s so I can still make something and then people start to complain about this even though it doesn’t bother them in anyway

TL;DR: Phone akku is draining, I steal our schools power. And secret plans to become rich.
My phone accumulator (heh, not a battery) DRAINS these days. It's fucking old and the temperatures are so hot that we actually afternoon classes are cancelled 🔥
So anyways, I'm sitting in the library (15 min break) and secretly charging my phone, devRanting on these wrongly configured, distorted monitors of this one computer that is connected with like 20 work stations xD
I'm stealing the schools power but the school owes me time (+2h of more useless sitting at school with my new timetable) - and time is money. And the schools money buys power. So I don't feel bad about it.
Actually a friend and me wanted to develop and install a plugin - when being able to bypass the reset-application in our school network - that uses the schools computers and their power to do crypto mining.
I wouldn't feel bad about it.4 -

I like learning and trying everything if I have the opportunity...backend, fronted, database, dev-ops, crypto, networking, virtualization...I stuck my nose in everything...but I see a lot of people moaning and despairing when they are thrown out of their comfort zone.

How much of fairness can human factor add to a government compared to foolproof AI algorithm.

Is AI more evil than today's politicians. Is there a project already similar to crypto currency on governance. On seeing all butt heads in power and in age where whistle blowers are caged I feel helpless tothink software cannot change the most primal thing - politics.

Is anyone here up for a long convoluted explanation of how exactly I predicted the last major btc peak/trough within just a couple hundred dollars?
There's actually a pretty precise reason it did what it did. Basically when china started tightening the screws, userbase fell along with price.
And when the price of an asset falls *with* userbase or ownership numbers, there is a delay in reevaluation, and therefore "current" market value doesn't accurately reflect true value.
I can show the math but again its convoluted. Has to do with userbase versus market cap.
Not a financial advisor fyi and I could be wrong.3 -
Hi friends of devRant. I'm looking for some advise.
I love learning new things(tech). I want to try out a lot of things like crypto, game dev, AR/VR, etc. I'm also a student and worried about my career. You know you just can't keep exploring technologies and not focus on a single track. Currently, I'm good with web dev. It feels so difficult at times. I hate leetcoding/competitive programming. So you can guess I'm not great with whiteboard interviews. How do I manage time to learn new things and also be able to land a job in a domain? Do you ever feel the same? Any career advise?5 -
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 -
Today I discovered trial and error driven development for myself:
Me, reading spec..
Spec: „Do something with an CSR“ (not the exact wording :D)
So instead of just googling C# + CSR and copying the code examples,
I went like:
What means CSR -> Certificate (Something Something)
-> could be this namespace (Something with „Crypto...“ in its name)
-> could be this class (Something with „Certificate“ in its name)
-> take the easiest overload (string is always nice)
-> try filling in the parameters from the spec
-> start debugger and inspect properties
-> repeat if necessary
I don’t know if this is the correct pattern to proceed my project with...
But hey, today it worked and now I also know, what „distinguished“ means -

Crypto. I've seen some horrible RC4 thrown around and heard of 3DES also being used, but luckily didn't lay my eyes upon it.
Now to my current crypto adventure.
Rule no.1: Never roll your own crypto.
They said.
So let's encrypt a file for upload. OK, there doesn't seem to be a clear standard, but ya'know combine asymmetric cipher to crypt the key with a symmetric. Should be easy. Take RSA and whatnot from some libraries. But let's obfuscate it a bit so nobody can reuse it. - Until today I thought the crypto was alright, but then there was something off. On two layers there were added hashes, timestamps or length fields, which enlarges the data to encrypt. Now it doesn't add up any more: Through padding and hash verification RSA from OpenSSL throws an error, because the data is too long (about 240 bytes possible, but 264 pumped in). Probably the lib used just didn't notify, silently truncating stuff or resorting to other means. Still investigation needed. - but apart from that: why the fuck add own hash verification, with weak non-cryptographic hashes(!) if the chosen RSA variant already has that with SHA-256. Why this sick generation of key material with some md5 artistic stunts - is there no cryptographically safe random source on Windows? Why directly pump some structs (with no padding and magic numbers) into the file? Just so it's a bit more fucked up?
Thanks, that worked.3 -

Noob question
Is it better to implement a cryptpgraphic algo in a function or in a class? Also how?
More info:
I have a cryptography class and I really enjoy implementing the different techniques that we study in class. At first I was just implementing the techniques in a simple function with 3 parameters; key, message and a bool for encryption or decryption. But as they are getting more complex, it is becoming harder to continue implementing them in a single function block. So I thought of using a class but ran into the problem of how do I even do that? Do I make different methods for key generation, encrypting and decrypting?
P.S. It's really just for learning how the crypto technique works and not for anything serious.12 -
Crypto! I've always thought of crypto as some complicated black box! How does it work, but then I did the cryptopals challenge and learned to exploit cryptography. What to do with this new found knowledge? Write new libraries and ransomware of course! So I present two projects that taught me a lot!
Pydhe, possibly the first(!!!) Open source diffie Hellman library for python. (Yea I know openssl, but they don't let you do diffie hellman without TLS. I do!) https://github.com/deadPix3l/pyDHE
And Cryptsky! One of the first ever fully python, opensource ransomware! (Again caveat, most open source python ransomware isn't truely licensed as OSS or uses some lower functions written in C)

Ticket: implement compression algorithm to crypto object x
Details: object to big, we must devise a way to compress it. A deflate algorithm should be added here, yada yada yada we did not have the time Yara yada...
Go see crypto provider's documentation... It has compression options... -_-
You lazy fucking stack overflow copy question dimwits!!! Jesus fucking Christ! This reached production like this shit, I've got clients complaining of the size of the payload because you are a bunch of lazy fucks who can't even read simple documentation!!!
I want to kill someone for wasting my time and patience... Don't call me for this kind of crap... I have better things to do!
I mean, the time it took you to write the ticket should suffice... -
I wonder if crypto exchanges are so damn vulnerable or just so transparent.
I mean, it is impossible to scroll tech articles for more than a few seconds before stumbling on a report of yet another crypto exchange being nicked a couple hundred mil USD.
- It could be that their security severely sucks (wouldn't blame them for it, most businesses do suck at securing shit).
- It could be that the entire black hat community is putting it's might on stealing money that is so fucking easy to launder.
- It could be that is damn nigh impossible to cover up a crypto hack since the evidence of coins drifting away is forever on display in the public ledger, and in that case crypto companies are not hacked more often than regular companies, they are just much more often publically shamed for it.
- It could be a mix of all the above, but my intuition is that one factor is more relevant.
Which would be the most relevant factor? One of the above or yet another attack vector to the stupidest value conduit ever?4 -
In android 7.1, I've seen a lot of conflicting reports about crypto security.
If I do something like the following in the default android 7.1 browser...
var array = new Uint32Array(n);
window.crypto.getRandomValues(array);
How secure would the resulting numbers be overall? I'm asking because I've seen a lot of articles talking about it, but they never specifically mention the default 7.1 android *browser* and what or how it obtains secure random numbers. They only ever talk about the api, sdk, and developers working in java.4 -
Fuck you Linux! I thought user password validation would be a piece of cake, like bash one liner. How wrong could I be!
Yeah, it's already ugly to grep hash and salt from /etc/shadow, but I could accept that. But then give me a friggin' tool to generate the hash. And of course the distro I chose has the wrong makepswd, OpenSSL is too old to have the new SHA-512 built in, as it should be a minimal installation I don't want to use perl or python...
And the stupid crypto function that would do me the job is even included in glibc. So it's only one line of C-code to give me all I want, but there is no package that would provide me this dull binary? Instead I will have to compile it myself and then again remove the compiler to keep image small?5 -
What are your thoughts on crypto?
BTC is like up 50% in the past month. But XRP is crashing?
And then there's all the other variations like litecoins, doge, etc30 -
So how you like opera accepting ipfs crypto domains ?
I just started being interested in it as it might move people to encrypted internet.
You think things like unstoppable domains and metamask are the future of internet ?
I can find anything useful that is on crypto domains right now.2 -
Nowadays every client wants to do something innovative with AI. It was same with crypto 4-5 years ago. I did lots of crypto projects during the time. Seems like AI gonna trending for few years.8

Guys check out IOTA, get a light node wallet and buy some as long as it is still low. It is rising at a rising rate since some hours now.
IOTA is the solution to bitcoins speed and scalability problems. IOTA does not use the blockchain but instead a network called the tangle, which enables decentralized peer-to-peer transactions. There are no miners, no fees and the transaction validation speed depends on how many people are using the currency. One transaction requires your device to validate 2 other transactions through proof of work and therefore the system can never be overloaded by too many transaction requests.
Be warned though, the IOTA foundation is only currently building up the infrastructure, and people are just starting to trade since a few weeks so trasactions still may take a few hours.3 -
Reply to my 2018 version: https://devrant.com/rants/1346392/...
Dear holodreamer ( version 2018 ),
I'm just glad that I'm still alive now. You won't believe how terrible 2020 is at the moment! Anyways, a lot has happened since you wrote me and I'm gonna reply it all to you.
Thanks for noticing. I really like my hairstyle now and my insecurity of going bald have gone. I couldn't be more happy.
Unfortunately, I'm not financially independent yet. Thanks to the crypto crash, the crypto ban in the country and some bad calls on my end. :/. But the good news is that we are back on the crypto market as the ban has been lifted recently. I don't have enough crypto to buy a lambo or go to the moon, but I have something that I could give to my grand kids. At this point, I don't really care anymore how much the value it is going to be, I have come to learn to think them of as a souvenir.
Your prediction of me preparing to move out of country seems to have come true. Honestly, I had given up that dream, but thanks to one of my best friend for reigniting those dreams - I may be moving somewhere really better by next year. I hope that I get this financial independence thing figured out before I move there. I don't wanna live there paycheck to paycheck.
Fortunately, I'm not getting any pressure to get married yet. I think I'm heading the way to a better life filled with some travel and adventures. I had a great opportunity to attend Google I/O 2020, but it got cancelled. Hopefully, covid19 will be over in few months.
Yea, I remember her. I got really carried away to the point that things she said started to hurt my heart. But eventually we had some argument and we stopped talking last September and I cut all contacts with her on the new years. If it makes you feel any better, last time i checked, she looks quite plumpy and totally different.
Thankfully, I'm not that lonely to need a chat bot. But I found some good online friends. They are fun to talk to.
No, AI didn't replace developers yet. Calm down! Javascript seems to be the most popular programming language now. But I hear there is a new contender to JavaScript that could change everything. It's called WebAssembly. Maybe in few years, we will see the decline of JavaScript.
Thinking about you, I feel some guilt for wasting your potential. I could have done much better if I was little more careful and responsible with you. I don't wanna make 2022 version of me feel bad for me.
Regards,
holodreamer ( version 2020 )1 -
Do you guys think that it would be possible to build a cryptocurrency that could replace traditional banking and money at all?
A non anonymous cryptocurrency, that could guarantee enough privacy to not be used for surveillance but at the same time could be used by common people.
I had this thought recently but at the time of writing ( :P ) I haven't enough knowledge and time to go deeper than this (meaning "nothing").14 -
Not really the place for this, I know. But I am a crypto coin guy. And I work with numerous coins. I was curious if anyone new of an app the could monitor all of your cryto-coin addresses and give you something of a portfolio value. I am capable of doing so manually but the prices flux a decent amount so it changes from day to day.6

TIL motherboards are volatile as fuck on price. In fact, mobos are less stable in value than most crypto.
Jesus fuck.
(The one B450M i saw is actually now $140-some and a nice X570 is currently $120. Why does the price of these fuckers change *daily?*)
as for case none under $100 are good so i picked some random mostly-mesh ATX mid case over my preferred ATX full case and i'm just gonna pray i can find some fan config that works because at this point i'm done with this shit fuck this, a bottom-barrel mobo, low-tier cpu and a decent case shouldn't be $400 or more15 -

Well, how i can start...
[Inspired on CipherSaber]
I wanna disguise arcfour as a game (board or virtual), give it for free to kids, and someday tell them the goverment has banned the game because it's basically undistingable from arcfour, and then i'll try to explain for them the crypto controversy, and i know i did my work well if at least one of them decides to write a letter to the goverment.
I mean, i clearly know this is so frigged up, but i wanna know if it could actually work. -
Does a crypto exchange supporting cashout into fiat on a bank account exists, where you actually can get through the KYC process as a foreigner in a european country?
Asking for a friend who already tried
Nominex, Bybit, Binance, Bitmax and Kucoin - all either without ability to transfer funds to a bank account or KYC broken for foreigners.4 -

I guess it has to be keybase. Keybase chat is now my go-to web based chat.
Using NaCl keys makes life so much easier but you have the choice of using PGP if you need to for encrypting files/text. -
all this talk of australian crypto laws got me thinking. here's a hypothetical (this might get a little complicated):
for the sake of the security facade, the government decides to not ban encryption outright. BUT they decide that all crypto will use the same key. therefore you can not directly read encrypted things, but it's not really encrypted anymore is it?
part two: there's a concept called chicken sexing, named after people who determine the sex of baby chicks. male chicks are pretty useless and expensive to keep alive, so they are eaten. female chicks go on to lay eggs, so ideally, from a financial standpoint, you only raise hens to maturity. this is nearly impossible to discern early on so at first you're just straight up guessing. is this one female? sure? that one? no? really 50/50. BUT if you have a skilled chicken sexer looking over your shoulder, saying right or wrong, then eventually you get better. why? nobody knows. they can't explain it. nobody can. you just sort of "know" when it's female or not. some people can do 1000s of chicks/hr with success up to 98% but nobody can explain how to tell them apart.
part three. final part:
after years, even decades of using this encryption with only one key, I wonder if people (even if only people who are regularly exposed to crypto like NSA analysts or cryptographers) can ever learn to understand it. in the same way as above. you don't know exactly what it says. or how you know it. you didn't run an algorithm in your head or decrypt it. but somehow you get the gist.
28464e294af01d1845bcd21 roughly translates to "just bought a PS5! WOOT!" or even just pick out details. PS5. excited. bought.
but how do you know that? idk. just do.
oh what a creepy future it has become.8 -
Hey DevRant fam :-) hope everyone is doing very well wherever you may be!, i'm currently on my uni break for roughly 3 or so weeks which is fabulous, now i do not have much experience with finance or crypto-currencies!, but i'd like to do something a bit different.
This is something i'd hope to put onto my portfolio, so my idea is something on the lines of a stock market simulator BUT with Crypto currencies, i've been asking people around uni but no help unfortunately!.
So its very similar to a stock market simulator app if you look at things like "Investopedia Stock market simulator" its very much the same concept. The user has x amount of USD or AUD (as an example) and they can buy BTC or Ripple and it either goes up in price or down :-).
So guys that's something id like to create :D i definitely know its difficult and i'm not so sure on how to start :-). If its possible to get some advice on how to start i'd greatly appreciate it!.
Hope you have a wonderful day/night where-ever you are!
(I apologize for rambling on)
Best

Had a talk yesterday about crypto and blockchain... Including NFTs... In that you could use real money like now to buy digital goods except you can transfer them and show them off anywhere online.
And well I'm suddenly wait... NFT + VR = Virtual worlds like Sword Art Online and Accel World....
Now we just need neurolink to work and then we'll have VR pods.... Like in the Matrix....
And then robots and machines will rule the world...
Oh fuck...26 -

Tried to buy some dogecoin today (for fun, no investment). Several people recommended okcoin. Unfortunately, I did not figure out how to deposit money there as the bank details they gave me did not include an IBAN and only some weird account numbers for a bank account in Malta.

Hey guys,
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 :)
Regards

Been learning more about crypto and blockchain (i know i know buzzword) but I mean I'm still a noob at pretty much everything so it was hard to find something that explains all that at a really technical level. BUT I then found www.cryptoeconomics.study

Everyone's stressing and regretting not buying/investing in Bitcoin when it was hella cheap way back when and now it's even harder to join in with the whole bubble view.
Don't mind me and my Forex though. I'm sticking with the other traders of actual currencies.1 -
Figured I'd share this in case anyones interested.
For those that are interested in investing the old fashion way (not getting rich quick off of crypto) Acorns is the first investing app I ever got into, used it for almost 3 years noe. Rounds up your change on digital purchases and invests it for you. Nice UI, makes it easy.
I'll drop an invite code down below if anyone is into investing since who doesn't like a free 5 bucks for using a specific link to sign up for something they're interested in? Just wish it wasn't US only.

I'm planning to do an app with some personal data for a small community (Verein). I want to save the data somehow encrypted so not all people can just access them. There will be just 4 persons who need to access this data. I'm think about PGP/GPG, with encrypting the data for these 4 people with their different keys, but I am not sure about that. So every person would have its own keypair. This is just the first idea. So if you have any hints/links on some ideas/blog posts how to do this or do it another way, I'd be glad about a comment. Thanks ;)

7 monthos ago, i invested a ridiculus amount of money on crypto. The day this month i decided to buy a battery for my loved laptop, i was notified that this crypto had doubled its price. Thanks Lord My God, i said, without any work and stress, i had 100% profit, i would totally buy the battery from the new money, i converted them all in euros, and started my odyssey.
Well, the platform, need 2fa to withdraw your money. But it did not inform you, it only had a popup saying "Reming me later".
WTF means "remind me later", for me it is something optional!!!! No red colours, no messages like (try again, your transactionr requires this ) etc.
Time is the only resource that do not come back, and i feel that my profit is already less, since the hour i spent searching, and searching, and then searching the chat (which is very well hidden...) and then chatting, and then writting this rant, i could have worked for the same amount of money.....5 -
Hey folks!
I have been trying to write a forex/crypto-currency trading bot. I am pretty good at trading manually but due to job & family responsibilities it has become difficult for me to make time for it now.
I am not sure where to start. I got the live market feed. and authentication ready. and some indicators and technical analysis functions ready.
Anyone doing the same kind things, I need suggestions on this. like strategies and things like that.
Please guide me in this regards. I am very much confused right now.
I need to automate this thing as soon as possible.5 -
Quick question.
I feel like I'm quickly developing a Bitcoin addiction. I've figured out how to backup my wallet to 'The cloud's by saving a file to Google drive in case I lose or spike my phone. Tested it out, it works. Got like 98% faith that the crypto is safe as far as not being able to access it like the dogecoin that's sitting on a phone that I still need to repair the screen of. First it was 20$, then 40$ in the BTC ATM. Felt like magic.
My question is:. Is you're opinion of me stupid?14 -
With stock market down, I want to get into some future tech trends cheap but which ones are good.... honestly don't think I can make much unless the prices jump 50-100%...
I see clean tech and 5g, but not really sure what 5g means. Not sure what the wow factor is...
Clean tech feels like we need to do it or we're screwed though I was also thinking about buying oil... But that's probably b not a good long term.
Crypto I don't think it doing to well and sorta goes against clean tech? So what else is there and thoughts?20 -
Ok this is either my code, socket.io or China. So I wrote DApp for my crypto project but for some reason our Chinese users have problems using it... So i dig through our code for HOURS! and finally resort to making an AJAX call from the client to a hideous PHP script for logging and what do i find?
For some reason the WebSocket cannot connect. I haven't mapped this so it's only conjecture but I think the GFW is blocking my users connections? (Also using a VPN seems to fix it)
Anyone else had this issue?1 -
A powerful bitcoin is harmful to the USA. Because the bitcoin-based crypto-economy bypasses the US sanctions. So the more bitcoin is used for international trade more the USA loses its manipulative and coercive control over the world economy. So it is essential to lower the value of bitcoin to maintain the imperial status of USD. A DRAMA that claims to seize bitcoin wallets without having access to the victim (here the attacker is the victim) will decrease the trust and lower the value of bitcoin. Such propaganda may regain the imperial power of the USD over international trade. It can be an insider's work, where the attacker's private key is already known. It can be a made-up story.17

Last year I spent several months working on a private project, which I thought was a (free) cool and helpful addition to the target audience. Was excited to finally release it to the public. But nobody cares, nobody is interested and nobody uses it. Can't even advertise it (on Facebook) because it is Crypto related. And other platforms (Reddit, StackExchange, ...) want $20k+ for a small ad campaign.6
