## [Why is there a "V" in SIGSEGV Segmentation Fault?](https://blog.cloudflare.com/why-is-there-a-v-in-sigsegv-segmentation-fault/)
A little bit of UNIX/POSIX based-operating systemas -- and something that
never actually made me wonder what it meant, specially considering the names
of the other interruptions and some internal commands (`creat`, for example).
## [ActivityPub Conference 2020](https://conf.activitypub.rocks/#home)
Ok, it is a bit early for this -- the CFP just opened -- but as a fan of what
ActivityPub proposes to solve, I must share this: A conference related to the
discussion of the protocol and its tools (well, I _guess_ that the topic,
anyway).
Stay tuned for the selected talks in the future.
## [On Git branch naming](http://meta.ath0.com/2020/06/git-branch-naming/)
The change of Git main branch name to something that is not "master" generated
some discussion online, even with the major Git services (Github, for example)
already announced that new repositories will get new names.
There is a problem with the meaning of the name and what it represents to a
significant part of the world population, but what the post shows is that even
if you ignore that, the name "master" makes no sense in the Git architecture;
it is based on the name used by BitKeeper, which had the master/slave
architecture, which Git _does not_ have.
And yes, I do agree with all the answers there. And: If it is a simple change,
won't break anything, and oppressed groups (in the past or present) don't get
offended, why not?
There is another point thought: Git is distributed, right? This means it has
not a central server; every installation is the central of itself. The same
goes for its branches, though: Every branch is a copy in itself and you don't
_have_ to put them all in the same basket at some point, e.g., merging back to
the main branch, because there is no _main_ branch. It is just a name and
doesn't hold any special functionality compared to other branches.
## [Understanding the Rust Ecosystem](https://joeprevite.com/rust-lang-ecosystem)
I tend to mention that "languages do not exist in a vacuum", and by that I
mean that you must not look only at some programming language or just a small
piece of it, but the whole; how is the ecosystem for this thing?
And, for Rust, it felt always a vibrant system, with all its weirdness and
coolness. And this post goes one step further showing most of the things going
around, from platforms, to forums, to meetups, to companies using the
language, to famous tools.
## [Diving into Rust with a CLI](https://kbknapp.dev/rust-cli/)
Speaking of Rust, Kevin K wrote this post about a command line tool to
download the XKCD comics. But instead of building the most simple solution for
it, he used the most known libraries for specific points (explaining why he
picked some) and showing a complete final solution.
I'm writing some other command line tool in Rust to explore more the language, and the current result is not even near the niceness of what is shown here.
## [Stop Blaming People: It’s a Design Problem](https://quinnkeast.com/writing/stop-blaming-people-its-a-design-problem/)
Developers are famous for not being able to design a button in the right way
or making it too damn hard to use the damn button -- or, in worse cases,
building an interface so cluttered with options that it is basically
impossible to use the application.
But it is not just the software world that suffers from that: the fire in the
Notre Dame Cathedral could be prevented if the interface didn't use some
indirect information; the ballistic missile warning in Hawaii wouldn't have
happened if the interface for the alarm wasn't so simplistic. 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`.

## [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 esse post mostra boa parte do que existe no sistema, de
plataformas, passando por forums, meetups, empresas que usam a linguagem e
indo até as ferramentas mais famosas.
## [Diving into Rust with a CLI](https://kbknapp.dev/rust-cli/)
Falando em Rust, Kevin K escreveu esse post sobre criar uma ferramenta de
linha de comando para baixar as tirinhas do XKCD. Mas ao invés de fazer isso
da forma mais simples possível para mostrar a linguagem, ele usou as
bibliotecas mais conhecidas para pontos específicos (explicando porque usou as
mesmas) e mostrando uma aplicação final completa.
Eu estou escrevendo uma outra ferramenta de linha de comando para aprender
mais sobre Rust e não chega nem de perto com o resultado apresentado aqui.
## [Stop Blaming People: It’s a Design Problem](https://quinnkeast.com/writing/stop-blaming-people-its-a-design-problem/)
Programadores são famosos por não conseguir desenhar um botão de forma correta
ou fazer com que seja extremamente complicado usar o maldito botão -- ou, em
piores casos, construindo uma interface com tantas opções que é praticamente
impossível usar a aplicação.
Mas não é só no mundo do software que essas coisas acontecem: O incêndio da
Catedral de Notre Dame poderia ter sido evitado se a interface não tivesse um
design indireto; o alarme de míssil balístico no Havaí não teria acontecido se
a interface para o alarme não fosse simplório. 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. O que me impressionou
do post foi essa linha aqui:
```
tar cf - /tmp/big_folder | ssh server 'tar xC /tmp/ -f -'
```
Basicamente, usando o `tar` para pegar o conteúdo de vários arquivos e
transformar numa sequência de bytes, enviar pelo stdout para o ssh e, de lá,
rodar o `tar` para desfazer a sequencia de bytes (transformando de volta em
arquivos separados). Curioso, e potencialmente 4x mais rápido que copiar os
arquivos diretamente por `scp`.
