curl cheat.sh — get an instant answer to any question on (almost) any programming language from the command line
tldr
do curl cht.sh/go/execute+external+program to see how to execute external program in go
And this question: why I actually should I start the browser, and the browser has to downloads tons of JS, CSS and HTML, render them thereafter, only to show me some small output,
some small text, number or even some plot. Why can't I do a trivial query from the command line
and instantly get what I want?
I decided to create some service that will work as I think such a service should work.
And that is how wttr.in was created.
Nowadays you probably know, how to check the weather from the command line, but if not:
curl wttr.in
or
curl wttr.in/Paris
(curl wetter in Paris if you want to know the weather in Paris)
After that several other services were created (the point was to check how good the console
can solve the task, so I tried to create services providing information
of various nature: text, numbers, plots, pseudo graphic etc.):
curl rate.sx/btc # to check exchange rate of any (crypto)currency
curl qrenco.de/google.com # to QRenco.de any text
And now last but not least, the gem in this collection: cheat.sh.
The original idea behind the service was just to deliver a various UNIX/Linux command line cheat sheets via curl. There are several beautiful community driven cheat sheet repositories such as tldr, but the problem is that to use them you have to install them first, and it is quite often that you have no time for it, you just want to quickly check some cheat sheet.
With cheat.sh you don't need to install anything, just do:
curl cheat.sh/tar (or whatever)
you will get a cheat sheet for this command (if such cheat sheet exists inf one of the most popular community-driven cheat sheet repositories; but it surely does).
But then I thought: why actually show only existing cheat sheets? Why not generate cheat sheets or better to say on the fly? And that is how the next major update of cheat.sh was created.
Now you can simply do:
curl cht.sh/python/copy+files
curl cht.sh/go/execute+external+program
curl cht.sh/js/async+file+read
or even
curl cht.sh/python/копировать+файл
curl cht.sh/ruby/Datei+löschen
curl cht.sh/lua/复制文件
and get your question answered
(cht.sh is an alias for cheat.sh).
And it does not matter what language have you used to ask the question. To be short, all pairs (human language => programming language) are supported.
One very important major advantage of console oriented interfaces is that they are easily
programmable and can be easily integrated with various systems.
For example, Vim and Emacs plugins were created by means of that you can
query the service directly from the editor so that you can just write your
questions in the buffer and convert them in code with a keystroke.
The service is of course far from the perfection,
there are plenty of things to be fixed and to be implemented,
but now you can see its contours and see the contours of this approach,
console oriented services.
The service (as well as the other mentioned above services) is opensource, its code is available here:
https://github.com/chubin/cheat.sh
What do you think about this service?
What do you think about this approach?
Have you already heard about these services before?
Have you used them?
If yes, what do you like about them and what are you missing?

WEB FUCKING THREE
Ok, some of this shit is interesting, let's get that out of the way:
Crypto - great for doing illegal things, great for financial speculation, interesting mathematically. But as likely to replace actual currency as I am to replace the fucking Queen.
NFT - should be written on the headstone of humanity. Entirely fucking useless, planet-roasting bro-wank dressed up as a revolution in...pretending to own shit. The only difference between a Bored Ape owner and my nephew pointing at a castle and insisting that it's his, is that he isn't thousands and thousands of pounds out of pocket by doing so.
Metaverse - AR and VR have been around before this dogshit rebrand, and they'll outlive it.
No, it's not that. It's that we now have a new species of parasite - the "Web3/Metaverse" LinkedIn guru insisting that this shit is even needed, let alone the next big thing.
Web 2.0 was a stupid fucking term alright, but it did represent a new generation of technologies that were badly needed, and adopted by the entire community. Web3 is a bunch of shit that some cunts think they can get rich off, so insist that we need. I wouldn't even give a fuck but I've already spent hours of my life explaining to clients and peers that this is UTTER FUCKING BOLLOCKS, there's no need for a blockchain in your app, there's no need for a blockchain in virtually anything. Yeah if you want some fucking 3d in your app or your page I'm your man, but if you keep saying 'metaverse' I'm going to fill it with easter eggs.
None of this shit was needed before and none of it is needed after. Have you looked at web3 games? It's Steve Buscemi asking 'how do you do, fellow computer games?', it's a fucking gambling app pretending to be something a human would do. Clash of Clans and Candy Crush already cornered the market for that type of fucking mug, right now you're making the Candy Crush business model look responsible and efficient. You CUNTS.47 -
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 -
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?

Case 1 - You sold the coins. And price continue to increase
Case. - Even when the coin reached it peak, you just hold the coins, because you learned something from Case 1. Eventually coin collapse.
And this continues in loop6 -
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

Dogecoin hit USD $0.40 recently, which means it's time for the Crypto Rant.
TL;DR: Dogecoin is shit and is logically guaranteed to eventually fall unless it is fundamentally changed.
===========================
If you know how Crypto works under the hood, you can skip to the next section. If you don't, here's the general xyz-coin formula:
Money is sent via transactions, which are validated by *anybody*.
Since transactions are validated by anybody, the system needs to make sure you're not fucking it up on purpose.
The current idea (that most coins use today) is called proof-of-work. In short, you're given an extremely difficult task, and the general idea is you wouldn't be willing to do that work if you were just going to fuck up the system.
For validating these transactions, you are rewarded twofold:
1) You are given a fixed-size prize of the currency from the system itself. This is how new currency is introduced, or "minted" if you prefer.
2) You are given variable-size and user-determined prize called "transaction fees", but it could be more accurately called a "bribe" since it's sole purpose is to entice miners to add YOUR transaction to their block.
This system of validation and reward is called mining.
===========================
This smaller section compares the design o f BTC to Dogecoin - which will lead to my final argument
In BTC, the time between blocks (chunks of data which record transactions and are added to the chain, hence blockchain) is ten minutes. Every ten minutes, BTC transactions are validated and new Bitcoins are born.
In Dogecoin, the time between blocks is only one minute. In Theory, this means that mining Dogecoin is about ten times easier, because the system expects you to be able to solve the proof of work in an average of one minute.
The huge difference between BTC and Doge is the block reward (Fixed amount; new coins minted). The block reward for BTC is somewhat complicated compared to Doge: It started as 50 BTC per block and every 4 years it is halved ("the great halving"). Right now it's 6.25 BTC per block. Soon, the block reward will be almost nothing until BTC hits it's max of 21 million bitcoins "minted".
Dogecoin reward is 10,000 coins per block. And it will be that way for the end of time - no maximum, no great halving. And remember, for every 1 BTC block mined, 10 Doge blocks are mined.
===========================
Bitcoin and Dogecoin are now the two most popular coins in pop culture. What makes me angry is the widespread misunderstanding of the differences between the two. It is likely that most investors buy Dogecoin thinking they're getting in "early" because it's so cheap. They think it's cheap because it isn't as popular as Bitcoin yet. They're wrong. It's cheap because of what's outlined in section two of this rant.
Dogecoin is actually not very far off Bitcoin. Do the math: there's a bit over 100 billion Dogecoin in circulation (130b). There's about 20 million BTC. Calculate their total CURRENT values:
130b * $0.40 = 52b
20m * $60k = 1.2t
...and Doge is rising much, much faster than BTC because of the aforementioned lack of understanding.
The most common thing I hear about Doge is that "nobody expects it to reach Bitcoin levels" (referring to being worth 60k a fucking coin). They don't realize that if Doge gets to be worth just $10 a coin, it will not just reach Bitcoin levels but overtake Bitcoin in value ($1.3T).
===========================
It's worth highlighting that Dogecoin is literally designed to fail. Since it lacks a cap on new coins being introduced, it's just simple math that no matter how much Doge rises, it will eventually be worthless. And it won't take centuries, remember that 100k new Doge are mined EVERY TEN MINUTES. 1,440 minutes in a day * 10K per minute is 14.4 million new coins per day. That's damn near every Bitcoin to ever exist mined every day in Dogecoin

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 -
Okay, fuck it. I'm going to buy $20 worth of every penny crypto currency until one of them explodes making me a millionaire

Anybody else feel like you've missed the crypto-currency bus?
It's one of my frequent regrets this past year, and I'm still figuring out how to get started earning some BTC.7 -
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.7 -
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? 😦

Apparently Razer is rewarding its users with "Razer Silver" - currency for use ONLY on Razer Products - if you install their crypto miner ("Razer Softminer") and earn them money? ...what???
https://www.razer.com/softminer
Thoughts? I think this is ridiculous. But I am also curious about it.5 -
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 -
Not sure if this is progress or what... But the people who asked me to fix their laptops or build their website now want me to help them out in starting their very own crypto currency.7

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 NEVER DID ANYTHING FUCKING RELATED TO CRYPTO CURRENCY! HOW DO YOU KNOW MY EMAIL?? LIKE WTF. 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?? WHAT DO YOU WANT?2

What is the best way to verify this?5 -
I don’t give a fuck about crypto currency, bitcoin and all the shit. I don’t even want to know how it works.

Where to begin learning about blockchain? (Google searches return way too much information.)
This has been in the back of my head for years now. And with all the attention that crypto currency has been getting lately, reminded me to look into this again.
Note: I don't actually care for cryto currencies, I'm just really curious about blockchain technology.4 -
Cybergoattechie ETH, USDC Recovery Firm.
It was never an easy ride to recovering my lost investment funds with the help of THECYBERGOAT RECOVERY FIRM. I lost my hard earned funds $600,000 worth of crypto currency when I invested with a binary option site. A broker I met on Instagram last year deceived and lured me into investing with their crypto company. It wasn’t the right decision by me trusting a total stranger with my hard earned funds which really hunted me. Without the recovery services of thecybergoat(@)techie. com, I could have been out on the streets since I could barely take care of the kids let alone paying the rents which were almost due to expire. thecybergoat professionals took control of my case after I had reached out to them which turned around my story. I was in awe the day when thecybergoat sent me an email requesting I send them my wallet that my lost investment funds have been " SUCCESSFULLY RETRIEVED " and on sending my wallet I received back most of my funds which I thought I had lost forever. about $430,000 was recouped. I never thought it would all end up in glory which is why I urge any victim of scam that there is refuge in thecybergoat team with their mind blowing and efficient recovery services. They were equipped with the necessary tools for a successful retrieval pushing themselves beyond their limits to attain remarkable results for their clients. Well, ask me about a recovery firm which is trustworthy and I tell you thecybergoat can be trusted with the retrieval of your lost investment funds. Don’t let doubts stop you from making the right decision and choosing the right and trustworthy recovery firm to handle your case, with the services of thecybergoat recovery firm, you can be sure of a successful retrieval of your lost investment funds.

How much of fairness can human factor add to a government compared to foolproof AI algorithm. Is it too early or too utopiaic to trust AI with governance compared to agenda based corporate embracing environment destructing corrupt to the core politicians. 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. Switching on TV and watching news had never been this disgusting. Flushing these thoughts , came back to my desk to learn something better and be at peace with programming.4

so guys, I am going to ask you about something I am totally new on it.

Monero is factually EPIC!2 -
Hey ranters does anyone know the best way to learn crypto currency. Its a very challenging topic for me5

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 -
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 -
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 -
