Mine is probably the crane or the jumping frog at this point, but I'm probably overlooking a ton of other cool traditional models. Anyone else have any they like to fold?

A community about origami, on Lemmy. From what I can tell, this is the very first community of its kind on Lemmy; a bit surprising, if you ask me. I've been getting more into trying to fold my own origami designs, and I run the instance where this community is hosted. I guess you could say my stake in the community is two-fold, but I wish to build a community that's more than paper-thin. If you like creating origami or want to learn more about it, please stop by. I'll probably release the first of my freely-licensed designs here, assuming I can create anything that isn't an eyesore. It would be cool if others did the same, but a place to share knowledge and cool folds is the real end goal. So, that's really it: origami, but on Lemmy.

This was one of my first attempts at using a repeating base pattern to create a more complex model. In other words, I basically folded a bird base in four smaller sections of the paper, which left me with several little subsections that I could fold in a way that added a more sculpted look. Since I was coincidentally using black and white paper and realized that I could fold the rear portion to look like a tail, I decided to try to fold a very oversimplified Orca. It has no dorsal fin, no anatomically-accurate underbelly, and little in the way of intrigue. Still, this is essentially my second design, and I think it's an interesting concept. I'm still not super happy with it, so I think I'll scrap it until I can create something better. Still, it's fun to share photos of folds like this, even when they aren't perfect.

ORIPA is the closest thing we have to CAD for origami. It's based on Java, although it does have binary builds for several major platforms. I couldn't get the Windows build to work, so I installed the OpenJDK and used the .jar file. The program is essentially based on editing a crease pattern, allowing you to visualize the final model in 3D. One of the killer features is that you can export the 3D view as a mesh, which means you could potentially edit it for 3D printing or create nice renders of your origami designs in Blender. It has many fold options available and should accommodate various origami styles.

I think one of the more promising ways to use this is to use it in tandem with a physical prototype for designing origami, as this gives you a clean template when you arrive at a design that you like. Some people have also mentioned that they design origami in this program before they ever fold it, which seems fairly difficult to me. Still, it's the closest thing I've found to a CAD program for origami, and it has a lot of features that make it genuinely useful. It's a bit rough around the edges, but it is a true little open-source gem that I imagine is easily overlooked for people new to origami.

This community was one of my main motivations to start a Lemmy instance. I'm a moderator of a few smaller tech/creative subs, and wanted to properly maintain a corner of Lemmy that felt a bit like Reddit. NormalCity is proving to be a fair bit of work, but I think it's worth it.

The Vaporwave Art community here on Lemmy is moderated by the same people as the subreddit, and NormalCity (our home instance) is hosted and operated by me. The goal is pretty simple: a place to post vaporware artwork. We don't really have too many criteria, and have a pretty strong legacy on Reddit of hosting weirder, more experimental artwork than some of our larger counterparts. I'll admit: I don't really like people telling me what is and isn't vaporware. I think the community can figure out what it likes, for the most part. So, if you're still looking for a just-visual-art place to dump your vaporware-inspired work, stop on by. I promise we won't bite, unless you post Outrun. We'll probably bite then.

I should add that this isn't the first time this has happened, but it is the first time since I reduced the allocation of RAM for PostgreSQL in the configuration file. I swore that that was the problem, but I guess not. It's been almost a full week without any usage spikes or service interruptions of this kind, but all of a sudden, my RAM and CPU are maxing out again at regular intervals. When this occurs, the instance is unreachable until the issue resolves itself, which seemingly takes 5-10 minutes.

The usage spikes only started today out of a seven-day graph; they are far above my idle usage.

I thought the issue was something to do with Lemmy periodically fetching some sort of remote data and slamming the database, which is why I reduced the RAM allocation for PostgreSQL to 1.5 GB instead of the full 2 GB. As you can see in the above graph, my idle resource utilization is really low. Since it's probably cut off from the image, I'll add that my disk utilization is currently 25-30%. Everything seemed to be in order for basically an entire week, but this problem showed up again.

Does anyone know what is causing this? Clearly, something is happening that is loading the server more than usual.

Hello,

I started seeing weird spikes in memory usage that result in the instance being unavailable via the web interface or via Jerboa. They seem to happen on a regular interval, although they seemingly only started today again. They don't seem to be correlated with bandwidth, so I'm not really sure what could be causing this. Perhaps someone here has more insight into this. I believe something like this was happening last week, which led me to bump the server specs in the hopes that it would resolve the issue. Now our idle/typical usage isn't anything to be concerned about, but these weird spikes are starting to cause timeouts and outages.

Hello, I noticed that my user count started going up much quicker than it should have. We probably have no more than 20-30 people on my instance at most, but the user count is now into the thousands.

~~I'm not really sure what could be causing this, but it seems like some sort of database issue. I recently upgraded the server plan, since it's a VPS. Perhaps sending the shutdown signal and not manually stopping the Docker container caused PostgreSQL to shit itself. (Yeah, this was probably a bad idea). While I'm a bit rusty, I did have a semester class on SQL that might come in handy. Any ideas on what I should do?~~

~~I suppose it could also be account spammers, so I did try and enable captchas. Unfortunately, email verification is still not an option for me to enable at this point. Assuming this was the issue, is there a way to remove the spam accounts?~~

The captcha did seem to stop the endless tick of the user count, but I'm not sure how we can get rid of the spam accounts.

I just used the tool linked here in the documentation to create a Bootstrap theme, but I can't find the folder they're referencing. I've used Ansible to install Lemmy, which is working fine, but I'm not really sure how to handle themes as a result. Do I place them somewhere in my Ansible stuff, or is there that directory somewhere on the server? I found the Docker /volumes/ folder, but the directory names were random strings and not labeled like they supposedly are at the link above.

Pretty awesome tacky-soundfont-filled remake-vaporwave-parody of sorts. It's based on Sea is a Lady by Toshiki Kadomatsu, one of the better city pop instrumental albums out there.

I used the Ansible playbook instructions and got my instance up and running, which is where I'm sending this from now. Still, I was not able to get the SMTP side of things working. Does this whole setup self-host SMTP on the Lemmy instance, or is it something I'll have to sort out externally? I've heard some people have had issues with Digital Ocean on certain ports, which is the VPS provider I'm hosting on, but even other ports I've tried have not worked.
