Just like the title said, I'm looking for people to talk to regularly.
Stuff about me: I play video games like fortnite, masterduel, elden ring (that's really it 😭). I like anime, manga, manhwa (ESPECIALLY ROMANCE MANHWA) and starting to read more novels as well. I listen to music (R&B). I honestly can't think of anything else so yeahh. I don't really care about gender or anything like that. (

2024.11.29 00:50 Worth_Singer Saw His New Girl Today
Well reddit... It finally happened. I saw who he left me for after almost 4 years. He broke up with me on August 1st, It's Nov 28th and they were already celebrating the holiday together at his parents house. I knew it was likely he was because of how he broke up with me. It's still hurts though. I thought I was better prepared but I'm just in shock overall really. Came here to yell into the void because I don't really have anyone I can share/vent with.

The dryer vent doesn't make it's way all the way outside and was/is throwing lint into the attic. What is the fix for this? I could take some wood cut a hole the size of the pipe but won't lint just build up in that cavity?

2024.11.29 00:50 iris_doll88 Jesus não "morreu para nos salvar".
Antes de tudo, esse post só pode fazer algum sentido para quem acredita na existência de Jesus.
Jesus morreu porque fomos cruéis. A ideia de que ele foi dado em sacrifício só foi adotada para que as pessoas que seguiam o judaísmo da época entendessem que o sacrifício de animais era desnecessário e deixassem essa prática, além de ajudar na aceitação de Jesus como Cristo. Ou seja, essa ideia veio como a substituição necessária de uma crença, e para a aceitação do povo judeu na época.
A pressão da opinião pública pesava sobre os discípulos. Eles não estavam felizes em dispensar o Velho Testamento por completo, uma vez que este tinha apoiado e unido os Judeus durante toda a sua história. No interesse de preservar o que eles consideravam valioso nos velhos decretos, adotou-se essa ideia. Para preservar a crença judaica na "salvação do castigo pelos pecados" por meio dos sacrifícios no Templo adotou-se a "pessoa de Jesus" como o "supremo" sacrifício, que pagou pelos pecados dos homens através de sua crucificação. Esta crença servia a muitos propósitos naquele tempo.
Mas ele não precisava realmente morrer na cruz. Não foi a crucificação de Jesus que nos "salvou", mas, sim, a sua vida e os seus ensinamentos. A sua crucificação era desnecessária e somente ocorreu por causa da crueldade humana.

Pyro: World Espionage
Infiltrate various sites to recover or destroy top secret files, then burn the evidence as you make your escape. How far can you go?
-------------------------
Still very much in-progress on this espionage-based firebug game, but it's functional enough now that I've posted it to the Pico-8 BBS for folks to play.
No in-game tutorials yet (instructions are on the BBS page), and it ends abruptly after Building 5. Curious to see how people feel about the functionality so far, and if you have any suggestions or ideas you'd like to see incorporated!

2024.11.29 00:50 Dartagnan11 Can this old 20A 240V be replaced with an EV plug?
Hi all, Our new (old-1974) house has a 20A 240V outlet garage and wondering if it would be ok to buy an EV plug and replace the old plug. I have no clue or data about when this old plug was installed, whether it’s original or not. We recently had our electrical panel upgraded and already had a NEMA 14-50 plug installed. Wondering if I need to get permit or would it be just as simple as a plug replacement if I’d be pursuing to add the second EV plug by means of replacing this old plug in the garage. The old one has its own dedicated 20A breaker in addition to the newly added NEMA 14-50’s specific breaker. Please feel free to share if it worths to convert this old plug to an EV plug and cons/pros. submitted by Dartagnan11 to electrical [link] [comments] |

2024.11.29 00:50 CrazyDolphin16 Ordered MSI G272QPF but recieved G272QPF-E2. Is it worth returning?
Title, I know there are differences in the stand and refresh rate but which monitor in your opinion is better? I can get the G272QPF and return the G272QPF-E2 for the same price.
It appears to be an MSI Warehouse Shipping mistake rather then an amazon mistake.
