home price / median income ratio. "Historically, an average house in the U.S. cost around 5 times the yearly household income. During the housing bubble of 2006 the ratio exceeded 7 - in other words, an average single family house in the United States cost more than 7 times the U.S. median annual household income." If this ratio is too high it could be a signal of housing bubble.

Why use Cloud Dataproc? "Dataproc is a managed Spark and Hadoop service that lets you take advantage of open source data tools for batch processing, querying, streaming, and machine learning. Dataproc automation helps you create clusters quickly, manage them easily, and save money by turning clusters off when you don't need them. With less time and money spent on administration, you can focus on your jobs and your data” - SOURCE google training workshop

Wit.ai
The most important goal for wit.ai in 2020-2021 (as seen in promotions in hackathons and developer jams) include:
multi modal applications using wit and Portal (not yet available to all developers), conversation model, conversation design, fitness, wellness.
Wit.ai can be the NLP layer of your app. It can make your web app and mobile app voice enabled, and smart with AI.
For authentication the wit.ai api uses a auth bearer token, which you must include in your API call.
Integration between Wit.ai and Facebook Messenger is readily available, natural and easy. It is frequently seen in hackathons.
Future and exciting projects using wit.ai: wit AI for daily usage, fitness, wellness seems to be active areas that Facebook is promoting during hackathons
Security wise it is unclear if your data goes through encryption. It also looks like Facebook will have access to the data (refer to term of service). You assume some ownership of the data, for example you can download the training data. Disclaimer: we are not lawyers, and we are unsure about the logistics of term of usage and the legal part of wit.ai

Moralis is a powerful Web3 framework for building decentralized apps (dapps). Moralis supports many chains both mainnets and testnets. That's impressive! Ethereum (and other EVM compatible chains and tokens), polygon, binance smart and now avalanche and fantom!! Rad! You can use moralis to build web3 apps quickly. By the way, Moralis has super good documentation, this blog post is just my personal notes. You really don't need it. But you can read it like a summary, initial walk through, guided tour. The moralis documentation is excellente.
Web3 dev platform. Great for creating dapps. Moralis API handles all the common tasks. Moralis projects are organized under email accounts, then each project has its own server (select net to be mainnet testnet ). Once a server is created you will get the API info: server URL app id and secrets.
01 In moralis dashboard initialize a server with your desired blockchain. Use testnet for tutorials and education purpose. Grab the server API key. Launch Moralis Server Initialize SDK in your app.
02 in your app.js or main.js first import moralis then initialize your moralis variables
03 All user info instantly in Moralis Server Database Tokens, MATIC, NFT Balances and Transaction once user logs in.
The server will automatically go to sleep after a period of non use.
Web3 APIs by Moralis : inspect the API endpoints in the admin panel. You can preview sokme of the functionalities and see what values are received as a part of the request. Moralis APIs : can retrieve all transactions in EVM compatible chains that are supported, also Solana. Retrieve all tokens.
It also provides some building blocks and really good looking UI for building DEX (this functionality is limited in the USA but is super useful in places where DEX's are allowed). Ivan talks about the potentially to charge referral fees. Do your own research, know your regulations. This is not advice, not professional advice, not production/commercial used. At your own risk. Crypto is very risky.
On Moralis API page/dashboard, we can see all the GET and POST methods available.
Example Solana API on
Solana API
GET /dateToBlock Gets the closest block of the provided date
GET /block/(block_number_or_hash} Gets block contents by block hash
GET {address}/logs Gets address logs
GET /block/block_number_or_hash)/nft/transfers Gets NFT transfers by bomber or block hash ?
GET /transaction/(transaction_hash} Get transaction details by transaction hash
POST
POST/address)/eventsaddress)/function
Gets events by topic …

A word on going live: WARNING and reminder our tutorials, codes and contents are not for production use. While you can go live, please use only testnet, throw-away wallet, wallet that contains no real tokens.
When developing on web3, you can test using a test node in one of the ethereum test networks, or a ganache local node, or a free hosted node provided by cloud flare. Blockchain, web3 and crypto applications must be thoroughly tested, using the industry best practice, and being audited and monitored regularly.
Hackers often target these applications. A reminder: warning our code base does not support production usage, does not support live, commercial usage. Our codes have not being tested in live/production/deployed environments. They cannot be used on mainnet. We are not liable for any costs, damages, losses. Please read our full disclaimer, terms of usage.
You have worked with different chains such as mainnet, testnet, or Ganache (Ganache is your own local development chain).
It must be hosted locally on your computer or publicly on a server like Netlify.
The easiest method is with the "Live Server" extension for Visual Studio Code.
You can also use Python's built-in web server.

Getting Start with Rust
Rust is a system language like C C++ and GO. It has included memory management. C++ requires DIY.
Task: Create a Rust project
$ cargo init
Definition: Cargo is the package manager for Rust
Task: run the main program in Rust. Source file has main function
$ cargo run
Main function is always the first function that will be executed when running rust. If one changes function to a different name will get error.
Task: Hello World with Rust.
pub fn hello(){
println!("Hello World!");
}
Task: import hello module. Mod is the keyword for module.
mod hello;
fn main(){
hello::hello();
}
Task: use :: syntax to call function in a module
module_name::function_name
Task : view startup scripts Scroll down to the bottom of package.json
"scripts":{
"start": "nodemon app.js",
"serve": "node",
}

We have been using Square Payroll for our startup. It takes care of filing and forms. Which is pretty amazing. You are probably familiar with Square payment POS point of sale system. Did you know it also offer free online shop and URLs (ecommerce portal like shopify), tracks inventory, . It also offers payroll, time card, team time tracker via the Square Team app, clock in clock out is easy. Payroll supports contractors and full time employees, handles direct deposit. We haven't tried it yet but these benefits and HR options are available : external HR as a service, benefits such as shopping for healthcare, retirement plan. So cool. It's a joy to not deal with these HR pain points. That makes a startup founder happy.
