TL;DR

Overivew

Setting up a linter can help detect odd or non-typical coding practices. The following will describe how to setup PyCharm for basic linting with the PyCharm PyLint plugin.

This assumes you have a venv setup within your current project.

Install Pylint

For pylint for your current project venv the following two commands should be run in your project root. The first will install pylint and the second will create an rc file which you can then adjust for your current project.

VIVA LA MAIN

A proposta é manter apenas uma branch: main.

Dev abre PR, e o CI roda testes, verifica se build passa, é feito code review e o merge é feito para main.

Todo código novo na main vai gerar uma nova CI e CD, uma release para ambiente de staging, onde é feito o QA pelas partes interessadas (Dev, QA, Product).

O controle do que pode ser exibido por ambiente é feito por feature flags, basicamente um if no código que verifica se no ambiente X (staging | production) a feature pode ser ativada ou desativada.

Lodash and Edge Runtimes

See: lodash/lodash#5862

Lodash uses Function(String) which upsets Next.js and is incompatible with CloudFlare workers (Vercel Edge), resulting in errors like:

Failed to compile.
Dynamic Code Evaluation (e. g. 'eval', 'new Function', 'WebAssembly.compile') not allowed in Edge Runtime

Matrix Synapse : how to prevent users from creating rooms or communities

This can be useful for admins running local synapse servers.

Forbid Group/Community creation

in order to prevent users from creating communities, there is an option: put in your /matrix/synapse/config/homeserver.yaml file:

	var net = require('net')

	var sock = net.connect(1337)

	process.stdin.pipe(sock)
	sock.pipe(process.stdout)

	sock.on('connect', function () {
	process.stdin.resume();
	process.stdin.setRawMode(true)

	/**
	* Requires node v0.7.7 or greater.
	*
	* To connect: $ curl -sSNT. localhost:8000
	*/

	var http = require('http')
	, repl = require('repl')
	, buf0 = new Buffer([0])

	// 'Hello World' nodejs6.10 runtime AWS Lambda function
	exports.handler = (event, context, callback) => {
	console.log('Hello, logs!');
	callback(null, 'great success');
	}
