zram + swapiness = infinite ram

Hello Linux folks, i would like to share one little hack which i have found. On fedora, `zram-generator` comes installed and configured by default with `lz4` algorithm i believe, and no disk swap, if you have 8gb of ram or more, that is fine, but if you have 4gb or less, `systemd-oomd` either kills your games when they use too much memory, or you face an OOMD and get your system frozen. When configuring fedora, normally i would create an in-disk swap, so that my computer wouldn't freeze but face a ***MASSIVE*** slowdown when on way too high memory usage, i also set `zram-generator` to use the `zstd` algorithm so that zram compression rate is higher but slightly slower, like that i can use my low memory more efficiently with a lower risk of OOMD. I was watching a bringus studios video once, where he tried to run counter-strike 2 on a ps4 using linux and proton; the game would always use too much memory and that would freeze the system before it got a change to actually launch, the strange ps4 linux was using in-disk swap, and so, increasing `swapiness` to 100 bringus tried to leverage that to make the game run. He was successful. In disk swap is very slow, so the performance was crap, but that does not matter...

While running modded Victoria 2 i have noticed my system using about 3.3 to 3.4GB of swap, and about 3.5 gb of ram, so about 100 to 200MB of real uncompressed memory usage, assuming zstd is running at level 1 of compression, and achieving at least 3.0 as compression rate, in thesis, my system has now the equivalent to 10GB of ram, well above it's weight! even more impressive considering how low are the numbers we are working here! tldr: setting your `swapiness=100` while using `zstd` as your `zram-generator` compression algorithm, and no in-disk swap will help your system use the most out of your ram with negligible performance penalty

Pengunta aos advogados/estudantes de direito

Olá, amigos do computador! Não consegui encontrar uma comunidade como c/pergunteaadvogados... Como qualquer Brasileiro nascido no nosso grande Bostil, tive de completar 18 anos em algum momento, ai veio bater a minha porta o tal do alistamento militar obrigatorio. Tenho alguns problemas físicos, como um de respiração e outro de circulação de sangue, mas tenho receio de não conseguir um laudo para estes a tempo, então escrevi um documento como plano B, este que tem o objetivo de provar a minha incompatibilidade com o serviço militar. Aos estudantes de direito, advogados, ou quaisquer que trabalhem ou tenham interesse na area, humildemente, peço ajuda de vocês para analisar o meu documento Obrigado! > DECLARAÇÃO DE INCOMPATIBILIDADE MORAL COM O AMBIENTE MILITAR Meu nome é XXX, com 18 anos, sou nascido no estado do Piauí, porém sou brasileiro como todos vocês. > Neste texto, venho declarar minha posição em relação ao alistamento militar obrigatório, previsto na Constituição Federal. Antes de mais nada, faço claro que minha posição não vem de um lugar de desrespeito, desprezo, desacato ou muito menos ódio, muito pelo contrario, possuo um respeito profundo pelas Forças Armadas, dado seu papel crucial na defesa da soberania e da paz do Brasil. Sou grato a todos que fazem valer a nossa bandeira por meio de seu serviço às Forças, porém, por razões éticas e filosóficas inerentemente relacionadas ao meu código ético, não posso ser considerado compatível com o ambiente militar. > A Constituição Federal de 1988, em seu artigo 5º, assegura a todos os brasileiros a liberdade de expressão, consciência e crença. O inciso IV estabelece que “é livre a manifestação do pensamento”, e o inciso VIII reforça que “ninguém será privado de direitos por motivo de crença religiosa ou de convicção filosófica ou política”. Invoco esses direitos para expressar minha visão contrária à incorporação ao serviço militar, uma vez que este entra em conflito com meus valores, ao criar um ambiente que valoriza a obediência absoluta, a rigidez e, em última instância, a violência. > A liberdade de expressão é um dos pilares fundamentais da nossa democracia. Através desse direito, desejo externar minhas convicções sem temer represálias. O serviço militar exige a aceitação de uma hierarquia rígida, na qual a obediência cega e a complacência tornam-se componentes centrais. No entanto, não acredito que uma sociedade feliz, livre e verdadeiramente justa se construa dessa forma. Para mim, a obediência absoluta significa abrir mão da capacidade de pensar criticamente e de cultivar o pensamento construtivo, este que é tão necessário em um mundo no qual a cultura de massas se torna cada vez mais forte, onde a capacidade de questionar, por vezes, caminha em direção à extinção. O pensamento crítico e a livre reflexão são, para mim, o que nos tornam não apenas homens, mas pessoas. > O artigo 143 da Constituição reconhece que, em tempos de paz, aqueles que, por convicção filosófica ou política, não se sintam aptos a cumprir o serviço militar podem optar por prestar um serviço alternativo à sociedade. Apoio-me nesse dispositivo legal, pois minha ética me afasta das práticas militares. Não acredito que a violência, seja ela legalizada ou não, seja uma forma eficiente de resolver conflitos. Para mim, o caminho para a resolução de conflitos deve ser o diálogo, a negociação, a educação e o cuidado. Esses valores me fazem incompatível a incorporação as Forças Armadas, sendo centrais a minha visão de mundo, não podem e não serão colocados a mesa para negociação. > A minha recusa ao serviço militar não representa uma fuga das minhas responsabilidades cívicas, muito pelo contrário. Ela reflete um compromisso profundo com o meu povo e a minha nação. Desejo contribuir para o desenvolvimento social, econômico e humano do nosso país por meio de métodos que não se coloquem a trair os meus valores. Com o amparo da Constituição, peço que minhas convicções sejam respeitadas. > Nossa Constituição não apenas permite, mas também incentiva que cidadãos sirvam o país de maneira digna e coerente com seus valores. Em uma sociedade democrática, o direito à diversidade de consciência, não violando a liberdade dos demais, é um componente fundamental não apenas para a construção, mas também para o fortalecimento de uma nação soberana, satisfeita e verdadeiramente unida. > Como cidadão brasileiro, solicito respeitosamente que meus direitos à liberdade de consciência, expressão e crença sejam feitos a valer, conforme instala a Constituição Brasileira de 1988 e conforma os faz visto pelo Artigo 109 do capitulo XVI no decreto n° 57.654 de 20 de janeiro de 1966. > A vocês, eu desejo o melhor, > XXX de YYY. > Referencias: > https://www.jusbrasil.com.br/topicos/10641516/artigo-5-da-constituicao-federal-de-1988 > https://www.jusbrasil.com.br/topicos/10673271/artigo-143-da-constituicao-federal-de-1988 > https://www.planalto.gov.br/ccivil_03/decreto/d57654.htm

anyone who uses Linux on apple silicon or another arm device

No, android does not count. Is there anyone who daily drives Linux on apple silicon or other ARM hardware? If so, then how is your experience, would you recommend it? For at least 3 years, I've been wanting to get an apple silicon mac to daily drive Linux on, lately I've been seriously considering getting one of these machines, or even other ARM hardware, like the thinkpad x13s or even the new Qualcomm laptops. I'm pretty much sold on a used macbook air m1 at this point, but I still wish to hear what other people have to say

Alistamento militar obrigatorio

Olá meus amigos! Completei 18 anos esse ano, e infelizmente, como todos os brasileiros (homens) fui obrigado a fazer o alistamento militar obrigatório, ontem fui até o tiro de guerra da minha cidade as 12:30 mais ou menos, onde tive de esperar das 13:00 até as 18:00 só para ter uma breve conversa com o sargento e ser liberado. Cheguei em casa bastante estressado por ter desperdiçado todo o meu tempo vendo videos de propaganda do exercito brasileiro em looping, pois era tudo que colocaram. Tudo isso só me ajudou a não querer participar disso ainda menos. Ainda tenho de retornar no dia 17 de setembro. Tenho diferenças ideologicas severas em relação as forças, e tudo que fui mostrado é que a tal “nação” brasileira que dizer lutar é uma completa fantasia e esta muito distante do real povo que vive neste país. Politicas aparte, para quem teve que lidar com essa inconveniencia a algum momento, independentemente do resultado, como foi a sua experiencia?

Migrant lemmurs. Who are you?

im sorry, but this might be a bit long... hello people of lemmy, this is not a question to all of you, but some. For context, im brazilian, i was born in the northeast region of my country, i was raised mostly by my two parents, and a family friend, who i call my aunt, also northeastern. in 2010, we migrated to the state of São Paulo, since, Piauí, the state we come from, and northeast region as a whole is quite subdeveloped. Life was hard there, which forced us to move. I came to here at around 6, and grew around the locals. Brazil is quite a big country, at around the same size of the continental united states, and with a size comparable to Europe. Its also quite densely populated for such a big single country, as such that one region has a radically different culture from another(like northeast(my home region) and the southeast(the region São Paulo is located at)). I for example, as a norteastern developed a mix of accent between my home region and the local accent. I am curious, you, which have faced a similar situation, moving from one region to another with the same, or similar language. Being migrating within the same country, or between different countries, how do you feel like? how do you talk? what do you identify with?
