And so on. + +Sometimes it is necessary to think a bit more about how the service will be +used instead of making things complex (or too simplistic). + +## [SCP - Familiar, Simple, Insecure, and Slow](https://gravitational.com/blog/scp-familiar-simple-insecure-slow/) + +I already knew SCp was slow, but I wasn't sure how slow. What impressed me +most in the post is this line here: + +``` +tar cf - /tmp/big_folder | ssh server 'tar xC /tmp/ -f -' +``` + +Basically, using `tar` to get the content of several files and turn it in a +single sequence of bytes, send it through stdout to ssh and, there, run `tar` +to undo the sequence (making them back into files). Curious, and potentially +4x faster than copying files directly through `scp`. diff --git a/content/links/20200620.pt.md b/content/links/20200620.pt.md new file mode 100644 index 0000000..3d90be5 --- /dev/null +++ b/content/links/20200620.pt.md @@ -0,0 +1,109 @@ ++++ +title = "Links Comentados de 2020-06-19" +date = 2020-06-20 + +[taxonomies] +tags = ["links", "sigsegv", "segmentation fault", "activitypub", +"conferência", "git", "branches", "nomes", "rust", "eco-sistema", +"linha de comando", "design", "scp"] ++++ + +SIGSEGV, Conferência de ActivityPub, Nomes de Branches no Git, O Eco-Sistema +do Rust, Apredendo Rust com Linha de Comando, Problemas de Design, SCP. + + + +## [Why is there a "V" in SIGSEGV Segmentation Fault?](https://blog.cloudflare.com/why-is-there-a-v-in-sigsegv-segmentation-fault/) + +Um pouco de história dos sistemas operacionais baseados em UNIX/POSIX -- e +algo que eu nunca me preocupei realmente, principalmente considerando os nomes +das outras interrupções e alguns comandos do sistema (`creat`, por exemplo). + +## [ActivityPub Conference 2020](https://conf.activitypub.rocks/#home) + +Eu sei que ainda é cedo para conversar sobre isso -- o "call for papers" +acabou de abrir -- mas como fã do que o ActivityPub se propõe a solucionar, eu +tenho que compartilhar: Uma conferência baseada na discussão do protocolo e as +ferramentas (bom, eu _acho_ que é sobre isso, de qualquer forma). + +Fiquem ligados para a lista de talks no futuro. + +## [On Git branch naming](http://meta.ath0.com/2020/06/git-branch-naming/) + +A troca do nome do branch principal do Git para algo que não seja "master" tem +dado alguma discussão por aí, mesmo com grandes representantes de Git (Github, +por exemplo) já terem anunciado que o nome vai mudar em novos repositórios. + +Existe sim uma questão sobre o significado do nome e o que ele representa para +um grupo significativo da população do mundo, mas o que o post mostra é que +mesmo ignorando isso, o nome "master" faz sentido na arquitetura do Git; +ele é baseado no nome utilizado pelo BitKeeper, que tinha uma arquitetura +mestre/servidor, que o Git _não_ copiou. + +E sim, eu concordo com todas as repostas apresentadas. E mais: Se é uma +mudança simples, não vai quebrar nada, e vai fazer com que grupos oprimidos +(no passado ou presente) não se sintam ofendidos, por que não? + +Mas tem mais um ponto: Git é distribuído, certo? Com isso, eu quero dizer que +não existe um servidor principal; toda instalação do Git é o principal de si +mesmo. O mesmo acontece com os branches: Todo branch é uma cópia auto contida +e você _não precisa_ colocar todas elas no mesmo balaio em algum ponto, por +exemplo, fazendo merge para o branch principal, porque _não existe_ um branch +principal. É só um nome e ele não tem nenhuma funcionalidade especial +comparado com outros branches. + +## [Understanding the Rust Ecosystem](https://joeprevite.com/rust-lang-ecosystem) + +Eu tenho falado que "linguagens não existem em um vácuo", e com isso eu quero +dizer que você não pode focar somente na linguagem ou numa parte relacionada a +ela, mas no todo; como é o eco-sistema dessa coisa? + +E Rust sempre me pareceu um sistema vibrante, com todas as suas esquisitices e +legalzices.

E assim por diante. + +Algumas vezes é preciso pensar um pouco mais sobre como o serviço vai ser +usado ao invés de deixar as coisas complexas (ou muito simplórias). + +## [SCP - Familiar, Simple, Insecure, and Slow](https://gravitational.com/blog/scp-familiar-simple-insecure-slow/) + +Que o SCP era lento eu já sabia, mas não sabia o quanto.
