Solução

A primeira coisa que fiz foi limpar a pasta C:\Users\Administrador\AppData\Local\Temp

Observe que no meu caso estava com o usuário Administrador, e na sequência fiz update/install com os comandos a seguir:

> pip install pip --upgrade

Requirement already satisfied: pip in c:\python\lib\site-packages (21.1.1)

> pip install setuptools --upgrade

Requirement already satisfied: setuptools in c:\python\lib\site-packages (49.2.1)

Espero que ajude, e se lhe ajudou comente!!!

Pasta System Volume Information

Quem já não tentou entrar nessa pasta System Volume Information que atire a primeira pedra!!!

Ai vem aquela mensagem chata seguida de som que você não tem permissão.   Affe, como não tem permissão ? O micro é meu, o Windows é meu (é pirata, mas é meu rsrsr), e eu faço o que quiser então eu tenho todo o direito de saber o que tem dentro:

Vá no menu Iniciar e cliente em executar, então digite CMD, e de enter, na linha de comando digite:

attrib -s -h -r "c:\System Volume Information" /s /d

Depois disso, pode ir no Windows Explorer para ver o conteúdo.

As pastas RPxxx  (por exemplo RP120) são os pontos de restauração que o windows cria, estes até podem ser apagados.  Dentro deste diretório também encontrará arquivos .cfg que contém informações sobre as partições do sistema, muito utilizada no carregamento do windows e arquivos .txt

Observação: Reforçando pastas RPs podem até ser apagadas para liberar espaço em disco, já os arquivos .txt e .cfg que encontram-se dentro deste diretório NÃO APAGUE.

Problemas para receber emails

Outro dia um usuário de um cliente ligou reclamando porque não conseguia receber os emails disparados por uma aplicação, no entanto, o seu outlook conseguia ler/enviar emails normalmente sendo que utilizava o mesmo provedor de emails.  Se você tiver um problema similar veja se no servidor de sua sua aplicação é realizado com sucesso os comandos abaixo:

-Porta Normal
telnet smtp.seudominio.com.br 25

-Porta Segura
telnet smtp.seudominio.com.br 587

Caso o telnet funcione é porque existe alguma diretiva de segurança no seu servidor impedindo a conexão.

Ping com Data e Hora

Gente para tudo!!! Chega de sofrimento. Chega de perda de tempo. Chega de pesquisar foruns e baixar mil e uma ferramentas para ter um ping com data e hora.  Simples:

ping -s 1 localhost   

Caso queira jogar num .txt

ping -s 1 localhost >c:\testeip.txt

Caso queria deixar rodando infinito (até um CTRL+C):

ping -t -s 1 localhost >c:\testeip.txt

outro exemplo:

ping -t -s 1 http://www.google.com/  >c:\testeip.txt
