Philip Withnall da empresa Endless falou<\/a><\/noindex> na confer\u00eancia GUADEC 2020 com a proposta<\/a><\/noindex> introduzir uma contabilidade do impacto do desenvolvimento de aplicativos GNOME no meio ambiente. Para cada aplicativo, sugere-se exibir o par\u00e2metro «Carbon Cost», que mostra o n\u00edvel aproximado de emiss\u00e3o de di\u00f3xido de carbono na atmosfera e permite avaliar como o desenvolvimento afeta o aquecimento global. <\/p>\n

De acordo com o apresentador, apesar de o software livre ser fornecido gratuitamente, ele tem um custo indireto \u2014 o impacto do desenvolvimento no meio ambiente. Por exemplo, a infraestrutura do servidor do projeto, servidores de integra\u00e7\u00e3o cont\u00ednua, o trabalho da organiza\u00e7\u00e3o sem fins lucrativos GNOME Foundation e a realiza\u00e7\u00e3o de confer\u00eancias de desenvolvedores exigem eletricidade e materiais, cujos processos de produ\u00e7\u00e3o levam \u00e0 emiss\u00e3o de di\u00f3xido de carbono na atmosfera. Os aplicativos tamb\u00e9m consomem energia nos sistemas dos usu\u00e1rios, o que tamb\u00e9m reflete indiretamente no meio ambiente.<\/p>\n

A introdu\u00e7\u00e3o de uma nova m\u00e9trica permitir\u00e1 demonstrar o compromisso s\u00e9rio do projeto GNOME com a preserva\u00e7\u00e3o do meio ambiente. Entre os fatores para o c\u00e1lculo da m\u00e9trica, menciona-se o tempo de execu\u00e7\u00e3o da aplica\u00e7\u00e3o, a carga na CPU, armazenamento e rede, a intensidade de teste no sistema de integra\u00e7\u00e3o cont\u00ednua. Para avaliar a carga, prop\u00f5e-se o uso de sysprof, mecanismos de contabilidade do systemd e powertop, cujos dados podem ser transformados em equivalente em emiss\u00f5es de di\u00f3xido de carbono. Por exemplo, 1 hora de carga intensa na CPU pode ser avaliada aproximadamente como 6 gramas CO2e<\/a><\/noindex> (com base no aumento do consumo de energia em 20 W), e 1 GB de dados transferidos pela rede como 17 gramas de CO2e. Quanto aos sistemas de integra\u00e7\u00e3o cont\u00ednua, a compila\u00e7\u00e3o do Glib \u00e9 avaliada em 48 quilos de CO2e por ano (para compara\u00e7\u00e3o, uma pessoa gera 4,1 toneladas de CO2e por ano).<\/p>\n

Para reduzir o «Carbon Cost», sugere-se que os desenvolvedores realizem otimiza\u00e7\u00f5es, como a implementa\u00e7\u00e3o de cache, aumento da efici\u00eancia do c\u00f3digo, redu\u00e7\u00e3o de carga na rede e uso de imagens pr\u00e9-definidas no sistema de integra\u00e7\u00e3o cont\u00ednua, contribuindo assim para a luta contra o aquecimento global. Por exemplo, o uso de imagens docker prontas no sistema de integra\u00e7\u00e3o cont\u00ednua pode reduzir o valor da m\u00e9trica em 4 vezes. <\/p>\n

Para cada lan\u00e7amento significativo, sugere-se calcular o «Carbon Cost» total, somando as m\u00e9tricas de todos os aplicativos, bem como os custos do projeto GNOME, o GNOME Foundation, hackfests e o sistema de integra\u00e7\u00e3o cont\u00ednua. Tal m\u00e9trica permitir\u00e1 que o desenvolvimento leve em considera\u00e7\u00e3o os impactos no meio ambiente, monitorando a din\u00e2mica e realizando as devidas otimiza\u00e7\u00f5es.<\/p>\n
