Mudança na assinatura GPG do meu website
Não me lembro exatamente mas acredito que a pelo menos dois anos eu assino as páginas HTML do meu site com GPG, faço isso para praticar soberania, autenticidade até mesmo promover ferramentas que auxiliam na privacidade.
Inicialmente eu deixava a assinatura GPG embutida no próprio conteúdo HTML, por exemplo:

Sabe aquela sensação de que algo não está certo? Pois é, ter a assinatura embutida nos meus arquivos HTML sempre me incomodou um pouco. Apesar de ser super prático validar a assinatura com um comando simples, tipo curl https://adlermedrado.com.br/missives/what-id-tell-my-23-year-old-self/ | gpg —verify, a ideia de ter a assinatura “colada” no arquivo original me incomodava. Parecia que o arquivo não era mais o original, né?

Update on the GPG Signing of My Website
I don’t remember exactly when I started, but for at least two years I’ve been signing the HTML pages on my website with GPG. I do this as a way to practice sovereignty, authenticity, and to promote tools that help protect privacy.
At first, I kept the GPG signature embedded directly in the HTML content, for example:
<!--

You know that feeling when something just doesn’t sit right? Yeah, having the GPG signature embedded inside my HTML files always bothered me a little.
Sure, it was super convenient to validate everything with a simple command like
curl https://adlermedrado.com.br/missives/what-id-tell-my-23-year-old-self/ | gpg --verify,
but the idea of having the signature “glued” to the original file just felt wrong.
It was like the file wasn’t really the original anymore, you know?

Ran my site through MDN’s security scanner and kept tweaking until I hit 120/100 (A+).
Checked the scan history and the very first one, back in 2018, scored 20/100 (F).
Always improving.

This website used to run on Cloudflare Pages. And being 100% honest with my visitors: I had all analytics disabled.
But I still wanted to know more about my traffic without compromising anyone’s privacy.
So I migrated everything to my own VPS. Now I use nothing but raw logs + GoAccess to understand what’s going on.
No JavaScript tracking, no fingerprinting, no big tech spy bullshit.
Nginx logs + GoAccess = enough intel to know what’s happening, without selling anyone out.

Há alguns meses eu reformulei este site, eu estava usando wordpress e não estava
muito feliz com isso, então decidi usar um gerador de páginas estáticas, nesse caso o Hugo.
No passado eu já utilizei o Pelican, o Jekyll e o Dangolino,
este último era uma ferramenta criada por mim, mas que descontinuei depois de algum tempo.
Se não me engano, há posts aqui falando sobre eles.
Por que assinar as páginas?
Eu vejo a criptografia como um mecanismo de defesa, acredito que as pessoas devem
criptografar tudo, para tentar garantir segurança, privacidade e autenticidade, entre outras coisas.

Publiquei a alguns minutos o planet adler que consiste em um espaço no meu site onde eu mostro o último post de blogs
que eu considero relevantes.
Eu acho interessante fazer algo do gênero por alguns motivos:
- Mostro aos visitantes do meu site os posts de blogs que considero interessantes. Difundindo a informação.
- Divulgo a outras pessoas os posts que considero interessantes, em alguns casos, as fontes para posts do meu próprio
blog.
Espero que você goste deste novo espaço e caso deseje que seu blog seja listado no meu blogroll, me envie um e-mail para
adlermedrado arroba gmail ponto com.

Como havia informado anteriormente, eu mudei meu blog de endereço. O novo endereço é http://adlermedrado.com.br/blog.
Eu criei também um site no endereço http://www.adlermedrado.com.br.
O Objetivo dessa mudança foi principalmente separar
meu blog do endereço da minha empresa e a criação do site, foi para retirar do blog alguns conteúdos que ao meu ver não
cabiam nele. Dessa maneira, meu blog continuará a existir, porém como ferramenta para inclusão de conteúdo apenas.
Eu pretendo iniciar em breve um tutorial sobre Zend Framework e todas as lições serão inclusas no blog.

Incluí no meu site uma área destinada à galeria de fotos. Eu coloco minhas fotos no flickr e não irei mudar isso.
O que eu fiz foi apenas um mashup onde eu busco as 10 últimas imagens que enviei ao flickr e coloco no meu site.
Implementar isso foi muito fácil utilizando o componente do Zend Framework para acesso à API do Flickr,
Zend_Services_Flickr.
Segue abaixo um exemplo de código para busca de imagens no Flickr utilizando o Zend Framework:

Depois de alguns anos com meu blog na URL http://neshertech.net/adler, irei movê-lo para um novo endereço.
Esta URL (neshertech.net) eu registrei para colocar o site da minha empresa (que eu ainda estou elaborando), porém,
aproveitei a infra-estrutura para hospedar o meu blog, mas essa semana eu registrei o domínio http://adlermedrado.com.br
que será utilizado para colocar meu blog e um site novo que implementarei para colocar meus projetos pessoais, minhas
idéias, galeria de fotos e etc. Dessa forma, irei separar o meu projeto pessoal do meu projeto profissional.
