Teleconferencing tips, advanced edition

Comments

In the last article I talked about how to teleconference without too much hassle; my main, key point was to wear headphones. But headphones can be a problem for some for various reasons (sensory issues, needing to get up and walk around, and so on).

Since I teleconference from a home recording studio, I have a reasonable amount of semi-pro audio gear. Lately I’ve been experimenting to see about a headphone-free setup that still works, and I’m pretty sure this setup is fine and workable. However, do note that it’s a lot more expensive than just wearing headphones.

Mosaic Palette 2S on an Artillery Genius

Comments

A few days ago my Palette 2S arrived, and I’ve been having some amount of fun with it. I won’t do a full review of it (there are plenty of those on YouTube, after all) but I’d like to talk about some of the things I’ve learned and how I have it set up.

Join me on Discord

Comments

Just as a reminder, if you’re bored and want to chat with other bored people about geeky things, I have a small but friendly Discord community. We mostly talk about the sorts of stuff I talk about here, but lots of hobbies are welcome.

I’m trying to keep it cozy and comfortable, so if you need somewhere that’s cozy and comfortable, hopefully this is a reasonable place for you!

Updates from Elsewhere

So, my cold symptoms came back somewhat today, so I took another sick day and took it easy. And now I’m feeling better, so, yay.

The last few days I’ve been having trouble with my sleep apnea again so I’m giving my CPAP another shot. Since I’m on new insurance and getting healthcare at a different place now maybe I’ll get a new sleep doctor who actually listens to my concerns instead of just taking shortcuts based on simple apnea.

I also of course still want to get tested for COVID-19, if only for peace of mind. I’m not fond of this constant uncertainty. If I can get a clean diagnosis I can stop having an anxiety attack every time I cough or feel short of breath. And on the off chance I do have the virus I know what to prepare for. (Plus I switch to no-contact grocery and food delivery for a while.)

Inside I’m going to ruminate about the virus itself.

Today’s Catalina iTunes Music gripe

Comments

iOS and watchOS have a great little remote control app for iTunes, which lets you control iTunes playback. It’s useful when I need to play or pause music during a typing break, or if I get a phone call while I’m in another room from my computer or whatever.

It’s supposed to work with Music.app.

It doesn’t.

I mean, it’ll pretend to connect just fine, but it never actually shows any of the playback information, and the controls do nothing.

Bonus fuckery: iTunes Match completely messed up the Fingertips suite on They Might Be Giants' Apollo 18. Tracks were out of order (yeah, yeah, I know it’s supposed to be shuffled but my brain has a thing) and half of them were glitched out and truncated.

Some tips for teleconferencing

Comments

Right now a whole bunch of people are starting to teleconference without having done such a thing before, and some of the hardware setup is a little bit unexpected. So speaking as someone who’s been doing teleconferencing for a while, here’s some tips to help everyone get along better:

  1. Please use headphones! If you do nothing else in this list, please do this. Headphone use alone will make the biggest difference. The reason for this is that your microphone will pick up sound from the speakers as well, and using headphones means that your audio won’t feed back into the microphone, so you won’t have feedback loops or echoes, and it will cut down on how much the software needs to do “echo cancellation” which is a big part of why you talking makes everyone else cut off.

  2. Also mute your speakers, if your headphones don’t do this automatically. If you’re using a laptop/tablet/phone this probably won’t be an issue, but on a desktop computer this might still be something you have to do yourself.

  3. If you’re not speaking, mute your microphone. Especially if there’s background noise (kids, cats, music, etc.) or if you have a cough or cold.

  4. Please try to limit the amount of background noise, as well; if you have a very meowy cat or barky dog, close your door with them on the other side (if possible). Turn off your radio or TV.

  5. Only connect/listen with one device at a time; this is sort of an extended version of point 1 above, but if you are listening in on a speakerphone or radio or TV or the like, using your headphones won’t prevent feedback from happening. Any noise that someone in the room can hear, your microphone can hear, and anything your microphone can hear gets broadcast back to the conference. You really don’t want your microphone to hear the other participants of the teleconference.

  6. If you’re on a laptop and don’t need to type during the conference, use the microphone on the laptop, which is almost certainly going to sound better than whatever’s on your headset. However, if you need to type, please use a headset with a built-in microphone instead; most laptops these days accept a 2.5mm telephone headset (the kind with four metal “rings” on the plug) and this will reduce the amount of keyboard noise that the microphone picks up.

  7. If you’re using a headset with a built-in microphone, make sure the microphone is clipped to your shirt rather than hanging loose. If it hangs loose it might brush against your shirt (which makes noise) or knock against your desk (which makes noise). These noises can be very distracting and disruptive to others on the conference.

  8. Similarly, please, please, please don’t join in while outdoors if you can help it; even the slightest breeze will also be picked up as a noisy rumble. (As will all background noise.)

  9. Finally: Most teleconferencing systems will show you if the microphone is picking up and sending your audio, or will have a test mechanism where you can check to see if it’s working. Please test this before joining in on the call, which will cut down on the amount of time you have to spend asking, “Can you hear me?” or having others ask, “Are you muted?”

With a little bit of effort we can all make our newly-found virtual presences go a lot more smoothly and less aggravating for everyone.

The ongoing quagmire that is iTunes Catalina Music.app

Comments

So, the latest issue with iTunes is that for whatever reason it’s stopped letting me actually play in a shuffle-from-library way. Which is to say, they got rid of the view where you can just see your whole library as the library, and click a “play” or “shuffle” button from there. I don’t know when it disappeared, but I know it used to be there, and now it isn’t.

It used to be that if you just had your view set to “albums” and pressed play anyway, it’d go ahead and choose something at random to play. But today it just kept on doing the same album: The Bends by Radiohead. Which is, granted, a great album, but I don’t know why it was choosing that one and that one alone, and I only felt like listening to it once, you know?

OctoPrint et al

Comments

So, my main reason for wanting to get a Canvas Hub was to have easy one-click print support that works with the Palette; after playing with Slic3r a bunch last night I then realized I also wanted OctoPrint for its print queue functionality to decouple the print process from Slic3r (which turns out to be rather unstable at times, at least on the Mac). But it turns out that Palette’s OctoPrint plugins work with plain ol' OctoPrint, too. So I looked into building an OctoPrint node… and then realized I was overcomplicating things, since OctoPrint doesn’t actually need dedicated hardware1 — it just needs to be on a computer that’s physically close to the printer and has multiple USB ports available.

My desktop computer is physically close to the printer and has multiple USB ports available.

So I looked to see if OctoPrint runs on macOS, and yes, it does; there’s nothing Linux- or ARM-specific about it, as it’s all written in Python. The macOS-specific guide is an okay starting point, but I saw a few things that could be a bit simpler, so here’s what I settled on.

(Also note that these directions should also work for Linux and even Windows users! There’s no reason to build an OctoPrint hardware node if you already have a computer that lives nearby your printer!)

The printer arrived!

Comments

So my new 3D printer arrived today. I went with the Artillery Genius, since it seemingly had the best blend of features and physical characteristics.

So far I like it, although wow the out-of-box experience could be a lot better. Not from the printer so much as from the software that drives it.
