  • I run a group that does free software programming education in Seoul. There’s a similar group in LA. When I came to Korea, I just set up a meetup account, paid the fee, rented some space, and started teaching people stuff and studying together. Great way to make friends. Been running it for 7 years now. I’ve had about a dozen or so people come say the group has helped them change their career to IT for the better. A dozen sounds like a small number, but it’s a huge impact on those people

    So be the change you want to see. If you have a skill that can help people improve their lives, whether it’s career or life stuff, share it! Learning a new skill is hard, and having a community to support you in learning, goes a long way






  • 100/100 for 22,000 KRW/month (about $16.50 USD).

    Other options with my provider:

    • 500/500 for 35,750 KRW ($26.85)
    • 1000/1000 for 41,250 KRW ($31)
    • 2500/2500 for 44,000 KRW ($33)
    • 5000/5000 for 55,000 KRW ($41.31)
    • 10000/10000 for 82,500 KRW ($62)

    And that 100/100 is effective. Shit downloads fast

    One of many, many reasons I’m not fond of going back to the US. Maybe Europe next, we’ll see. For now, Korea is pretty sweet





  • Maybe I’m part of the problem, and if so, please educate me, but I’m not understanding why blocking is ineffective…?

    And block lists seem like an effective method to me.

    The security improvements described seem reasonable, so it would be nice to get those merged.

    I understand that curation and block lists require effort, but that’s the nature of an open platform. If you don’t want an open platform, that’s cool, too. Just create an instance that’s defederated by default and whitelist, then create a sectioned-off Fediverse of instances that align with your moderation principles.

    I feel like I’ve gotta be missing something here. These solutions seem painfully obvious, but that usually means I’m missing some key caveat. Can someone fill me in?



  • My dude, I think you’re not super familiar with these technologies.

    The most basic form of a content delivery network is a set of globally distributed servers that replicate content from a source of truth and a network to direct traffic to the closest server with a valid replica. So the cost here is servers.

    With Lemmy, this problem is solved by eliminating the need for individuals to own many servers and a lack of need for trust between servers. The effort and cost is distributed among individual humans, making it manageable.

    Now, if you’re familiar with blockchain, you probably perked up when you heard “lack of need for trust.” That’s what the blockchain was built for! Perfect fit, right? Ehh, not so much.

    There’s two problems: acting as a proxy for content requires trust, and some single service needs to direct clients to the right local server. If I can arbitrarily join some network of serving content, I can always tell other servers in the network that I’m serving what they ask… and then serve ads. There’s no (reasonable and fast) way for the network to verify that I’m serving the correct content to every client. There’s no way to avoid the need for trust. Additionally, DNS, which directs you from mysite.com to 120.1.2.1, isn’t intelligent. It can’t direct clients to a geographically (or route-efficient, fucking ISPs) local IP. The best it can do is pick a random one from the pool. So when you go to lemmy.world, DNS can’t pick the correct server for you. So some set of servers needs to do the logic to select which local server to actually get content from. Those servers need to be central for the whole content delivery network.

    This company you linked is just another company using “blockchain” to get investment money. If you read through their page to get a cursory understanding of how things work, an easy question comes up: what is the purpose of media tokens? Sure, maybe you can buy CDN time with it, but when you pay that token to someone providing compute… what do they do with that token? It’s worthless, just like crypto currency. Fucking scams. All that said, blockchain is a super, super interesting technology. There’s just very, very few suitable applications of it.

    I’ve worked in IT for about 12 years now. Everything from infrastructure monitoring to data analysis to data engineering to DevOps to backend engineering to product management. I’ve worked with systems serving tens of users and tens of millions of users. Happy to answer any questions. I love this shit.

    If someone could figure out a trustless, decentralized way to implement a CDN, I’d eat that up in a second, but with my current understanding of the internet and available technologies, I don’t see a way it can work. At least, not with making every web page take >3s to load, which would absolutely kill websites.







  • My understanding isn’t perfect, but I’ll share what i understand so far.

    An instance starts federation with another instance when a user requests content from the other instance. This starts the sync.

    An instance’s admins can block federation/content sharing with another instance explicitly.

    I’m not sure of a way to see a kind of map of federation, but it would be cool

    If your instance, A, blocks instance B, I’m not sure if you can see instance B’s users’ posts on instance C. That’s beyond my knowledge

    I hope this helps?


  • I’m not 100% sure this is correct because I haven’t looked at the protocol or implementations in detail yet, but I can offer some educated guesses.

    “Pending” implies that you’re waiting for some remote service, likely the other instance, to confirm that the subscription went through.

    I can think of a few reasons why an instance may never send confirmation or why the message may not update:

    • that instance defederated your instance, meaning you can see them, but they refuse to see you. This makes sense for beehaw, given that they’ve defederated several instances, including lemmy.world
    • that instance hit an error
    • the request or response was lost somewhere along the network
    • your client, that is, the website or mobile app you’re using, has a cached state of pending and never updated it even though it received confirmation

    Maybe I’ll dive into things tonight and get more info. Or i might forget. We’ll see 😅
