Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Python library to retrieve data from TradingView
I've been working on a Python library which lets the user retrieve data from TradingView.com so it could be used in backtesting a strategy. The project is called TvDatafeedLive and is available on GitHub. To be fair, the project is actually an extension of a project called TvDatafeed, which is a really good project, but only supports retrieving historic data (so far). So, I've taken the liberty to fork it and implement retrieving data continously and "real-time". The data is retrieved in Pandas DataFrames and can easily be plugged into backtrader. There is instructions included in the GitHub page. If this sounds interesting then please check it out and leave feedback if there are any thoughts.

TradingView Charts for Pancakeswap Tokens
just did a quick search for you, first pass returned this on github https://github.com/StreamAlpha/tvdatafeed but be aware I have NOT looked into it or done anything other than read to description, it could be all scammy as fuck I dunno, so recommend you just check it out and anti others that are similar, and see if maybe they can't give you some inspiration on how to go about coding exactly what you want. good luck!

Blockchain transactions decoding: making wallet activity understandable
Event is a log entity which EVM smart contracts can emit during transaction execution. Events are very good at signalling that an some action has taken place on-chain. Applications can subscribe and listen to events to trigger some off-chain logic or they can index, transform and store events in some off-chain storage (look at The Graph protocol or Ethereum ETL).

Is Nethereum's GetContractQueryHandler decentralized? If not what's a decentralized alternative for C#?
There are also decentralized network services like The Graph or Pocket Network that provide decentralized access to Ethereum and other blockchain networks. Note that these services primarily provide APIs for querying blockchain data, and may not provide full functionality for sending transactions or executing smart contracts like a full Ethereum node or services like Infura and Alchemy.

Is it possible to create subgraphs to query other blockchains that arent supported on the hosted service?
Yes, you can. You'll have to run your own graph-node See: https://github.com/graphprotocol/graph-node

ETH Data pipeline ?
If you only looking to index events of a couple contracts you can use https://thegraph.com to deploy a sub graph for fetching real time data form those contracts

Gitpod x Blockchain
First lets see this repo StoreFront_contracts This project is build with hardhat and also has TheGraph powered indexer in subgraph. The project provides NFT based smart contract like ERC721 build on top of openzeppelin contracts.

How is building in web3 different from building in web2?
Does blockchain tech replace the backend? Absolutely...Not 👀 As I said, web3 is an addition, supplementary and will not replace existing tech. In major blockchain applications, getting data from smart contracts can cost time and sometimes fail if the RPC is unresponsive. You would still want a database and API to query data collected from smart contracts from, say, events. Examples: The Graph, Moralis.
