This 32-bit computer made in Terraria can play Pong and run Linux

Jump

  • I think whoever wrote this article mistook the fact the project itself is only fully supported on Linux, but possibly can run on Windows with use of the WSL (Windows Subsystem for Linux). These are system requirements for the host PC, not the in-game computer. Good luck running modern linux or windows on 96kb of ram.

    • Why won't fediverse instances bloat and pop?

  • Basically, data storage is cheap. Currently it can cost as low as $0.01/day for other instances to store the content that is being sent by the largest communities. Otherwise instances can clear out old data and let the larger instances be the archive hosts.

    • Is there a way of "merging" multiple related communities into a single view in the lemmy 'federation'? detailed question inside

  • Q1: Correct

    Q2: Not at present, but it's a highly requested feature. I would imagine it will be around soontm in one form or another.

    • Does Lemmy really benefit from Rust? Is code execution speed the bottleneck?

  • The numbers are a little higher than you mention (currently ~3.2k active users). The server isn't very powerful either, it's now running on a dedicated server with 6 cores/12 threads and 32 gb ram. Other public instances are using larger servers, such as lemmy.world running on a AMD EPYC 7502P 32 Cores “Rome” CPU and 128GB RAM or sh.itjust.works running on 24 cores and 64GB of RAM. Without running one of these larger instances, I cannot tell what the bottleneck is.

    The issues I've heard with federation are currently how ActivityPub is implemented, and possibly the fact all upvotes are federated individually. This means every upvote causes a federation queue to be built, and with a ton of users this would pile up fast. Multiply this by all the instances an instance is connected to and you have an exponential increase in requests. ActivityPub is the same protocol used by other federated servers, including Mastodon which had growing pains but appears to be running large instances smoothly now.

    Other than that, websockets seem to be a big issue, but is being resolved in 0.18. It also appears every connected user gets all the information being federated, which is the cause for the spam of posts being prepended to the top of the feed. I wouldn't be surprised if people are already botting content scrapers/posters as well, which might cause a flood of new content which has to get federated which causes queues to back up; this is mostly speculation though.

    As it goes with development, generally you focus on feature sets first. Optimization comes once you reach a point a code-freeze makes sense, then you can work on speeding things up without new features breaking stuff. This might be an issue for new users temporarily, but this project wasn't expecting a sudden increase in demand. This is a great way to show where inefficiencies are and improve performance is though. I have no doubt these will be resolved in a timely manner.

    My personal node seems to use minimal resources, not having even registered compared to my other services. Looking at the process manager the postgres/lemmy backend/frontend use ~250MB of RAM.

    For now, staying off lemmy.ml and moving communities to other instances is probably best. The use case of large instances anywhere near the scale of reddit wasn't the goal of the project until reddit users sought alternatives. We can't expect to show up here and demand it work how we want without a little patience and contributing.

    • YSK that kbin.social is now federating, adding hundreds of communities and ~26k more users content

  • Neither seems to work for me, maybe federation is overloaded with the sudden influx? I'll report back if it ends up working.
