Bem-vindo(a)!

Esta é o Lemmy Português, uma instância de Lemmy direcionada a utilizadores e comunidades Portuguesas, ou de Língua Portuguesa.
Servidores disponibilizados pela WebTejo.


Regras

Para o bom funcionamento deste espaço, existem regras e um código de conduta que deve ser sempre seguido.

  1. Respeita todos e mantém uma atitude acolhedora. Isto implica não recorrer a insultos, humilhações, ataques pessoais, etc. Sê tolerante.
  2. Publicação ou ameaças de publicação de informações privadas (doxxing, mensagens diretas, etc) é estritamente proibido.
  3. Usa linguagem percetível por todos e uma gramática correta. Este espaço pretende ser inclusivo, e isso só é possível se todos formos capazes de comunicar bem.
  4. Nada de conteúdo NSFW.
  5. Qualquer conteúdo de teor traumático, perturbador ou que conte o enredo de algum livro, filme, série ou jogo deve ser marcado como tal e escondido (spoiler).
  6. É inaceitável tentar passar por uma outra pessoa.

Por fim, usa senso comum.

O incumprimento de qualquer uma destas regras resultará num aviso. Caso o problema persista, o utilizador será banido.

ℹ️ Estas regras serão expandidas e um documento de código de conduta redigido, na comunidade Regras, quando o Lemmy suportar melhores controlos de moderação para comunidades.


Registo de contas e criação de comunidades

Devido ao aparecimento de trolls e de contas automáticas que poluem a rede com conteúdo indesejado, o registo de novas contas foi restringido, sendo agora necessário não só um endereço de correio eletrónico, como o preenchimento de uma pequena "candidatura" que terá que ser aprovada por um administrador antes da conta ser ativada.

Pelo mesmo motivo, a criação de comunidades está sujeita a uma restrição semelhante. Será necessário fazer uma publicação na comunidade Meta, com título e corpo adequados, para requisitar a criação de uma nova comunidade.

Por fim, é igualmente possível requisitar a posição de moderador numa das comunidades originais ou numa que não possua nenhum moderador ativo. Em qualquer dos casos, haverá um processo de avaliação antes da promoção, por motivos de segurança.

Para mais informações, deves ler a barra lateral da comunidade Meta.


WebTejo

Esta instância corre num servidor da WebTejo, uma empresa de alojamento web independente e nacional. Deem uma vista de olhos 😉


Ajudar a correr esta instância

liberapay

O servidor onde a instância está alojada custa ~10€/mês. Eu consigo cobrir parte dos custos, mas para garantir o seu suave funcionamento, é necessária algum auxílio. Ninguém se deve sentir no dever de doar o que seja, porém àqueles e àquelas que têm a possibilidade e a vontade, qualquer ajuda é muito bem-vinda :)

Eis a página de LiberaPay onde é possível fazer um donativo: https://liberapay.com/lemmy.pt/
Num futuro próximo vai ser estabelecido um repositório com registos mensais de donativos e despesas, de modo a existir maior transparência no financiamento da instância. Fiquem atentos.


Matrix

Existe uma sala na rede Matrix dedicado a esta instância de Lemmy. Aqui, além de discussões sobre a instância, os administradores vão publicando avisos relativamente a problemas técnicos e interrupções de serviço. Junta-te a #tuga-lemmy:matrix.org para participares na conversa!

Existem também outras salas portuguesas que podes ver aderindo ao espaço #espacotuga:matrix.org.

Também é possível entrar em contacto com os administradores através das mensagens privadas da plataforma, ou por correio eletrónico.


Traduzir o Lemmy

Sendo apologistas do movimento de software livre e da ideia de redes federadas, temos contribuído para o projecto através da tradução para Português. Este processo é realizado através da instância de Weblate (uma ferramenta de tradução, também ela livre) do projecto Lemmy, e que pode ser econtrada em https://weblate.join-lemmy.org Qualquer sugestão de tradução é bem-vinda!

Discussão sobre a tradução do projecto pode ser feita na sala de Matrix acima referida, ou, alternativamente, numa outra sala sobre tradução em geral, em #tuga-traducao:matrix.org

Original Title: TIL that Satoshi Tajiri, the creator of Pokémon, loved to collect bugs as a child. Other children would call him “Mr. Bug,” and as a child he wanted to become an entomologist. This childhood pastime went on to inspire aspects of Pokémon.

For his Abu Dhabi-set science fiction graphic novel Solarblader, Emirati writer Mo Abedin focuses his speculative fiction on renewable energy, inspired by the initiatives happening in the current-day UAE. Dubbing the new subgenre "solarpunk", due to the reliance on solar energy in his version of the future, he hopes to inspire a new trend.

Sandstorm debuted the first volume of Abedin’s graphic novel titled Solarblade at this year's Middle East Film and Comic Con, which ends today. Set in an alternate-universe Abu Dhabi in 2525, it imagines the UAE capital fully reliant on solar energy, bolstered by alien technology that helps harness the full power of the sun.

I present to you all !absoluteunit@sh.itjust.works, a community themed around very big things that are bigger than one might expect.

Basically, an absolute unit is either an animal, a person, an object or anything else that is bigger than it's usually expected, like a very big vegetable, a very big dog, a very big building and so on, basically anything that can be very big. Here is a more detailed explanation.

So yeah, if you ever encountered something bigger than normal you can post it there!

Have fun! Hope you like it!

"If you can't respect the basic fundamental underlying principles with which we order society — which is 'Do not steal' — then what are you left with?" asks investigative journalist Carole Cadwalladr. Following her TED2025 stage talk, Cadwalladr is in conversation with Chris Anderson, head of TED, to warn about surveillance fascism. What happens when big Silicon Valley companies take over communication platforms and weaponize intellectual property against you? She suggests that when you feel powerless, it's often actually because you are powerful — and explores why it's so important to fight information chaos by supporting independent media and journalists.

Yesterday evening, Tesla reported first-quarter earnings for 2025, and they were abysmal: Profits dropped 71% from the same time last year.

Musk sounded bitter on the call with investors that followed, blaming the company’s misfortune on protesters who have raged at Tesla dealerships around the world over his role running DOGE and his ardent support of far-right politicians.

“The protests that you’ll see out there, they’re very organized. They’re paid for,” he said, without evidence.

Data collection is ubiquitous. Data are useful for a variety of purposes, from supporting research to helping allocate political representation. It benefits society to enable data use for such purposes, but it’s also important to protect people’s privacy in the process. Organizations across industry and government are increasingly turning to differential privacy (DP), an approach to privacy-preserving data analysis that limits how much information about an individual is learned from an analysis. Chances are DP has been used to provide a privacy guarantee for an analysis of your data: Companies like Google, Apple, Meta, Microsoft, and Uber, as well as government agencies like the U.S. Census Bureau have all used it in the past several years.

Not all differential privacy systems are created equal, though. The strength of privacy protections offered by DP depends on a “privacy loss budget” parameter, called epsilon. Epsilon is a measure of the amount of information “leaked” about individuals from the use of their data. This value can be chosen to be anything from zero to infinity, where smaller epsilon values correspond to stronger levels of privacy protections. Privacy protections can vary wildly according to how epsilon is set: bigger epsilons can leak much more information about individuals. For example, when epsilon is 0.1, an observer or attacker is 1.1 times more likely to learn something about you, compared to if they had never seen your data. If epsilon is 10, this becomes 22,000 times more likely. Despite epsilon’s importance as an indicator of privacy risk, it is seldom communicated to the people whose personal data are used by technology companies and other large organizations. This is in part because epsilon is difficult to reason about, even among experts. It is a unitless and contextless parameter, making it challenging to map onto real-world outcomes. Furthermore, it specifies probabilistic guarantees, meaning people must reason under uncertainty to fully grasp its implications. However, not explaining epsilon to people who are deciding whether to share their data under DP leaves them ill-informed about the protections that are being offered.
