Setting up Github developer access tokens | Debugging git push not working requires | How to get Github Access Token

Access token is now required for Github repo git push as of August 13, 2021.  This post solves git push does not work due to authentication errors. After August 13, 2021, Github requires access tokens instead of password login. This post covers how to get github access token for your own developer account. It solves when using receiving "remote: Support for password authentication was removed on August 13, 2021." error message after using git push

remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.

remote: Please see https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/ for more information.

See the screenshot below to go to setting > developer setting > personal access tokens to generate your access token. For max security select a recent expiration date.

You will also select the appropriate permissions, for example will need to select the repos permission to make git push work. 

https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token

Github log in with token

Now that you generated the developer token (which you have to do whenever the previous expires), you will need to log in with the token. authenticate github using access token

Now you will need to remove the old credentials. Warning: this is tricky, you might be logged out, and lose progress, so please do your own research, and only use these commands if you know what you are doing. Read more on the github documentation below. 

git credential-osxkeychain erase

host=github.com

protocol=https

https://docs.github.com/en/get-started/getting-started-with-git/updating-credentials-from-the-macos-keychain

When using a command that requires access token, such as git push, you will be asked to authenticate. Enter your username like you normally would, instead of password, use access token for the second part. If you lose it, you can repeat the earlier step and generate a new one. Delete the old one that you no longer need.

Blockchain, cryptocurrency, NFT, DAO Lifestyle

Welcome to the crypto renaissance! Live a futuristic, ideal, cool lifestyle in Web3, enabled by blockchain technology, cryptocurrency, and DAOs. 

Why is NFT so popular right now? NFT made many price records in 2021: "Decentraland, most of the recent headlines have been about digital art being sold for eye-popping prices. This includes a $560K New York Times column, Beeple’s $69M JPEG, a $7M Cryptopunk icon, and Jack Dorsey’s $2.9M tweet, among others." CBInsights

First, warning, please read our disclaimer: 

Conference: 

NFT

Famous NFTs : Bored Ape Yacht Club (BAYC), Degenerate Ape Academy, and CryptoPunks. All are on OpenSea. Watch out for copy minters elsewhere. Each NFT has different traits properties, some are digitally rare, and perceived to have different personalities, different desirability. A common thread: red laser eyes are considered crypto maximalists, and are expensive

#NFTNYC, largest NFT conference, 

Bored ape yacht club party, warehouse event, and exclusive meetup

NFT Use Case: 

NFT can partner with consumer brands. NFT can be luxury goods. NFT can be wearables. NFT can deliver fashion : Karl Lagerfeld, fashion icon, figurine sold out in less than one hour. 

Token:

What can be tokenized? It seems that everything is being tokenized. Art, NBA plays,

Once inside look for the NFT gallery, free workshop (12 languages), and a teleporting portal to decentraland - another famous, gamified 3D space, the NFT exhibit there is cool.

It's insane how many NFTs were given to VIP attendees and general attendees at GeckoCon. People who paid full price early for the VIP ticket definitely got the most NFTs. There were partnership with Sandbox, Cometh and even a soccer NFT.

If you have a .eth ENS name totally use it, so that you are recognizable. I am collaborating with madamcrypto.eth yay.

Some people had access troubles, for that you will need to email the team. There's an email in the order confirmation email. Also you can join the discord and ask questions there. 

There are fours roles in discord admin, premium (for premium gecko subscribers), attendees and VIP attendees.

Really cool NFT giveaway and Poap

The VIP ticket is actually a Poap. That's pretty rad. You can also enter a raffle with that. There are also NFT drops from Tezos and Gala. Some Gecko themed. Some of us missed the NFTs. It ran out OR we bought the ticket late OR didn't fill out the form in time OR the email notification went into spam folder. Tragedy indeed.

Sponsors of GeckoCon are impressive! State of #NFT right now. Though sales isn't as stellar, the number of wallet has crossed a major threshold #crypto pic.twitter.com/btTeDnVIeR

State of NFT:

Trends

• Number of wallets is an important metric. Participation widened.
• Market Distribution: collectible non-fungible temporarily is no.1, but he thinks art and META are next.
• Currently NFT weekly sales in August is absolutely crazy, much more than 6 months ago.
• There's a sharp fall at the end of the active wallet slide because data retrieval ended before week end. It's not a true drop off.
• There are more buyers than sellers.
• People are buying more assets, not buying SUPER expensive outlier assets.
• Market distribution: there are star assets like Axie Infinity (No.1 / No.2 spot), Crypto Punk, Bored Ape Yacht Club, ....
• Data : cryptopunks are extremely centralized, invested by market makers not just average users. Nonfungible.com estimates only 2/3 of the cryptopunks are circulation. People claimed punks for free but forgot or lost the key.Top 10 punks have the 27% of the total supply of punks. That's highly centralized.
• Metric: retention rate

Metaverse session

• In the metaverse even the car you are driving around is an NFT, Rad!

Music session

Gotchiverse:

• There three distributions of land before end of year alpha go live
• One land distribution already happened. One likely to be in December. One last one right before the alpha go live
• Main mechanism is farming, there's also crafting 4 building blocks. The citadel is safe to farm. Phase 2 robots will be introduced outside land.

What is a Smart Contract? - Blockchain tech explained

 What's a smart contract? Chainlink explains it really well. Be sure to read our disclaimer before proceeding to read the tutorial.  Please always read our disclaimers and terms of service before reading our posts. 

"When deployed to a blockchain, a smart contract is a set of instructions that can be executed without intervention from third parties. The code of a smart contract determines how it responds to input, just like the code of any other computer program.

A valuable feature of smart contracts is that they can store and manage on-chain assets (like ETH or ERC20 tokens), just like you can with an Ethereum wallet. Because they have an on-chain address like a wallet, they can do everything any other address can. This opens the door for programming automated actions when receiving and transferring assets.

Smart contracts can connect to real-world market prices of assets to produce powerful applications. Being able to securely connect smart contracts with off-chain data and services is what makes them hybrid smart contracts. This is done with oracles, which we will discuss later in this tutorial."

The language for programming smart contracts is solidity. 

"Solidity is a statically-typed curly-braces programming language designed for developing smart contracts that run on Ethereum."  official doc. Inspired by other programming languages. .sol extension. solidity is for smart contract programming.

Ethereum virtual machine : where ethereum programs are run

Remix : online playground / editor for trying out and running solidity code in the browser.

^ to specify version greater than the one specified.

smart contracts are essential a bunch of codes that are to be executed.

kind of like a microservice, everyone can see it, and execute the code. Look like a class but more than a class.

An example of smart contract - Chainlink

In the screenshot above, you can see this smart contract has one variable, publicly accessible - message. When initiated, the message would have been set, and there's also a function to update that variable. 

The first pragma specifies the version of solidity. The main logic is enclosed in a class like contract HelloWorld{ ... }.

Smart contract vulnerability, loop hole, failure can cause severe losses, hacking of tokens, assets, exchanges and just about any dapps. We often hear genesis smart contract problems being exploited. This not a component of blockchain that you should be coding yourself, don't re-invent the wheel. Only use well tested, audited contracts written by experienced, top developers. This is not a component you will want to hack together. A reminder: please read our disclaimer and term of usage: to summarize our tutorials and posts are for informationaly purpose only. They are not for production use, not for commercial use. They have not gone through security review. They are just toy examples.

One interesting trivia about solidity contracts is that it does not allow decimals aka floating point numbers as a data type.

int defaults to int256
