Luiz dev environment

• Visual Code

• Github

• Terminator

• Metamask

• Hardhat

• Truffle

• npm - npm install -g npm@latest

• nodejs

• sudo apt-get install vlc (pra ver videos mp4)

• setar no github ssh e gpg key

• fazer L3150 funcionar em Ubuntu: https://tutorialforlinux.com/2020/03/11/step-by-step-driver-epson-l3150-l3160-ubuntu-20-04-installation/ Pra configurar impressora e wifi, entrar wifi direct na impressora, entrar local http://192.168.223.1/ e se for outro link, imprimir página de relatorio que nela sai a url. aí entrar em conf avançadas e configurar a rede wifi manualmente (ssid e senha). aí depois é só ir em adicionar impressora que acha a impressora e adicionar. usar aplicativo no celular pra ver config de setup da impressora, como limpar cabeçote e níverl de tinta. pq no linux é chato fazer configurar.

  comandos linux df -h (mostra espaço linux) df -i (mostra inodes) netstat -atunp (mostra todas as portas e ips ) ps -ef (mostra todos os processos) top (mostra resumo do sistema, consume de memória - NI mostra prioridade e -20 é o máximo de prioridade) du -sh * (mostra o tamanho dos arquivos) crtl + r (reverse search do history) alt+t (reverte o que digitou)

  comandos docker docker stop $(docker ps -a -q)
