  • One could make a community named “Anon Posting” or something, lock it so only a mod can post, and then make the sole mod a bot that would post anything it got via DM (probably after automoding, rate limiting, etc) to said community.

    I do think it’s a good idea for the bot to keep a log in case it gets abused for sufficiently evil purposes. One could add some extra functionality to the bot that would give identifying information about the poster to instance admins on demand (via DM), but I think instance admins would have pretty easy access to all DMs made to the bot, along with identifying information anyway. (Feel free to correct me if I’m wrong on that.)

    Also, the bot could totally delete its logs and with them the identities of all posters after a while. Maybe a month?

    And, of course, this wouldn’t be ironclad anonymity. But it would keep identities secret from anyone but the bot maintainer and instance admins.

    Yeah, sounds like a pretty cool concept. Not volunteering to write such a bot (at least any time soon) or anything, but I support it.










  • I never would have thought to print them at an angle like that, but thinking it through, I bet relative to other obvious-ish options, it a) improved part strength (particularly along the axes where you most need strength), b) saved a bit of material, c) improved bed adhesion. Smart move in general. I’ll have to keep that approach in mind for my own prints.


  • I haven’t watched the video yet, but just because it’s relevant to the topic…

    I used to stream to Twitch with just ffmpeg. No OBS or anything.

    I mostly did speedruns, and I needed a timer, so I wrote my own. I had ffmpeg read the current time to display from a file in /tmp/ and had a Go program that would write to that file at the same rate as the framerate at which I was streaming. Worked really well, actually.

    I also made some videos (mostly tutorials for pulling off certain glitches in The Legend Of Zelda: Breath Of The Wild) and put them on YouTube. I edited those entirely with ffmpeg and a pretty simple Bash script.

    I’m definitely not going to claim they were what you might generally recognize as “well-edited” videos, but they did the job. And I definitely wasn’t really looking to “make it big” on YouTube or anything, so I wasn’t looking to polish my videos.

    Here is one of my videos for reference. And here is a clip of a VOD from one of my streams that demonstrates the timer I mentioned.



  • The way I’ve embedded magnets in prints in the past was to:

    • Design a magnet-shaped (plus like 0.2mm of clearance) cavity into the print, but leave it completely “closed off” to where it’s “inside” the print.
    • But only “closed off” by like 2 or 3 layers (I was printing at 0.2mm layer height for this particular print).
    • Use “pause at layer” functionality in my slicer (I used Cura at the time) to pause just before the first layer that would “close off” that cavity.
    • Start the print and when it pauses, drop the magnet into the cavity.

    Yes, I was a bit nervous about the magnet potentially jumping up and sticking to some ferromagnetic metal that’s part of the print head, but that didn’t happen in my case. YMMV, I guess.

    I guess theoretically it could also be the case that the heat from printing could weaken the magnet, but again, that wasn’t an issue in my case.

    Just to elaborate on what my project was, I had a freely-spinning part that I wanted to be able to fix in place or unfix. I fashioned a “stop” that when engaged would fix the freely-spinning part in place. The way it works is that the stop can move freely up and down. Putting it in the “down” position fixes the freely-spinning part in place and gravity keeps it engaged. But to disengage it, you slide it straight up. At the top of the “track” in which it slides is where I put the magnet. I used the same technique as described above to embed a little stack of about four staples into the stop itself. So, by sliding the stop to the top of the track, the magnet attracts the staples, keeping the stop disengaged until you pull it back down again to where gravity will keep it engaged until you move it back up.



  • I’m not sure why you’re getting downvotes exactly.

    A basic tutorial on web development like Sleepless One suggested is definitely a good place to start, just to get a basic overview of what you’re getting into. I personally learn best by doing rather than by learning. What I mean by that is if I sit down to try to learn… say… the C programming language, I’m probably not going to learn much from it, let alone retain it. But if I decide I want to write a game in C and start writing the game even from what little I know about C, I’ll learn as I go. Not to say for me there’s no benefit in a “learn C” tutorial, but if you’re anything like me, I’d recommend switching to doing the specific website you have in mind as early as possible rather than trying to “learn web development” before switching to the project that is ultimately your end goal.

    Beyond that, you’ll want to avoid falling into a trap of doing what feels to you like it’ll work rather than what’s “best practices” for “the industry.” So the other thing I think will benefit you searching-wise is to look for information about not just how to make it (technically) work but also how to do the thing you want to do “right.”

    At least that’s my recommendation.

    Beyond that, are there any existing websites that closely approximate what you have in mind for an end goal for your project? If so, could you share one? I think it might help us with more specific recommendations.
