Imagem partilhada em 9 de Abril, na altura estava ainda a tratar das fun\u00e7\u00f5es de subnetting, e a reduzir o flickering, al\u00e9m de relembrar o pessoal de que estava a fazer aquilo sem librarias externas (fazer do zero). Descri\u00e7\u00e3o abaixo.

\u00abAinda de volta disto, mas n\u00e3o \u00e9 pela parte do subnetting, \u00e9 redu\u00e7\u00e3o do flickering do ecr\u00e3, alterar cores \u00e0 pata, brincar com o cursor do terminal, etc.

Porque n\u00e3o vou usar librarias que fa\u00e7am isto, tem de ser feito \u00e0 pata desde o 0, toda a manipula\u00e7\u00e3o de texto no ecr\u00e3, poderia usar uma libraria enorme e tinha a coisa feita, mas fica pesado, lento, execut\u00e1vel grande, etc, e eu curto fazer \u00e0 pata sempre que poss\u00edvel.

J\u00e1 n\u00e3o tem flickering o ecr\u00e3, est\u00e1 soft, e amanh\u00e3 trato das cores e de criar um menu para isto.

Conhe\u00e7o quem diria “para qu\u00ea reinventar a roda?”, mas isso \u00e9 pessoal que usa librarias j\u00e1 feitas, faz coisas \u00e0 pressa, e ficam com execut\u00e1veis de 1 mega ou 1001 depend\u00eancias e n\u00e3o quero depend\u00eancias. Este j\u00e1 tem 50KB mas a ver se continua por aqui, poderia ter menos mas tamb\u00e9m n\u00e3o vou exagerar, j\u00e1 usei v\u00e1rias librarias standard, n\u00e3o usarei \u00e9 cenas gigantes, como a manipula\u00e7\u00e3o de texto, essas farei \u00e0 pata.

Mas depois de feita, poderei reutilizar noutros programas que fa\u00e7a, por isso n\u00e3o \u00e9 tempo perdido.
