The puzzler: Building a 20-person mix-delete audio routing template in my Pretty Good Jacktrip Toolkit crashes (moderately-sized) Linode servers. They seem to crash when automating large numbers of Jack-connection adds or deletes — issuing a delete-all with JMESS for example.
The hypothesis: Jack works OK, it’s the number of connections per endpoint that’s causing the trouble.
The idea to get around this (so far): split the mix-minus routing in two by putting players in sections.
Clogged sandpaper leading to burns in the wood has always been a big problem with my PerformaX (JET) 16-32 drum sander. I’m hopeful that this is the fix — replacing the cover to provide a connection for a 4″ dust collection hose (from the current model) rather than the original one which connected a 2.5″ hose. Here are the pictures — which started just before COVID and end… today, almost a year and a half later.
Here’s a step-by-step post about routing Jacktrip audio using Rogue Amoeba’s Loopback software. Loopback is a for-money successor to Soundflower and similar to BlackHole. I like it because it is more visual and does more stuff.
The goal of this post is to get a person with a 2×2 interface going with a setup that will let them join a Jacktrip session reliably, without having to “rewire” things each time. It also covers things like routing audio into and out of other audio software like Logic Pro, Ableton Live, Max and Zoom.
Alas, this is for Mac folks only. Windows audio puzzles me. I don’t have a clue how to do this on a Windows machine.
There are links to short videos that “animate” each of these steps and examples. Click on the pictures to embiggify and read them.
Here’s the rig that that Marcie uses to take pictures of things at microscope scale. We took a long journey through a lot of attempts that were unsatisfactory — perhaps this post will save you some steps.
Here’s a picture of the whole setup (click on the photos to embiggen).
many thanks for the invitation to throw a few words into the virtual gathering. here’s a collection of WORT memory-jogger photos, starting off with a few pages from early program guides, that tell a lot of the story of the early days. clicking on the newsletter-page photos brings up bigger versions.

here’s Numero Uno – volume 1 number 1. my writing style in those days was a completely-hopeless attempt, by an illiterate geek, to emulate my hero Lorenzo Milam. Milam was guiding light for a gaggle of us who started stations all over the country — we lost him this year (2020), along with so many others.
a pretty good exposition about why most of us did all that work – it was fun, we made lots of good friends and we kinda took care of each other. Jeff Lange did a lot of the graphics for the first-generation newsletters including everything on this page (i think). Continue reading →
Here’s a scratchpad on how Jacktrip Hub Mode does audio routing as of early September 2020.
Starting the server in Hub Mode (capital-S instead of lower-case S) with the “-p” option offers four ways to configure the server. Here’s an example launch string that would fire up a server in Mode 2:
jacktrip -S -p2
Mode – 0 (the default – my machine hears everybody and everybody hears the mix that I send them)
Here’s a video and a recipe for musicians who want to display something other than a web-cam of themselves when performing in an ensemble. Maybe graphics, or animation. Especially interesting is to insert a Syphon stream into the mix. Here’s one way to do that. Sorry — I only cover Mac software here. Continue reading →
This is a scratchpad post to remind myself how to decontaminate our well the next time it tests positive for bacteria. I bet we have to do this every time we get flood runoff, but I’m willing to be proven wrong. Related post: Winterize the RV
I decided to compare some digital recorders for the purposes of recording soundscapes here at Prairie Haven. I’ve got two of them, bought at different times for different purposes and I was curious to see how much different they were and whether it was worth carrying one of them instead just using my phone. The nice thing about the phone is that it’s with me all the time, but I’d start carrying one of the others if they were better. Continue reading →
Exactly five years ago today, I published this little rant about the growth rates projected for the new “generic top level domains” that were being introduced by ICANN at the time. You know, domain names that end in things like .run or .lol or .bot (yep, those are all real alternatives to .com or .org if you’d like to strike out into new territory).
We’ve been noticing that the Ranger has been pretty tough on our trails here at Prairie Haven. Our pet theory is that the EV (plug in electric) version of the Ranger is quite a bit heavier than a normal one and that the standard (narrow, aggressive-tread) tires add to the problem.
The Mission: wider tires for the Ranger EV
We’ve just mounted four Carlysle 25x11x12 Multi-Trac (574369) turf tires . These are a little wider than the standard tires and have a much less aggressive tread pattern. Here’s Marcie on her test drive — early returns are positive.
This one’s going to get the least hits ever, I bet.
I transferred the authoritative nameserver of a domain from Godaddy to Cloudflare and things got stuck. The NS propagated pretty well, but it never got picked up by Google or Verisign’s public DNS (check with https://www.whatsmydns.net). Since my ISP uses Google’s 220.127.116.11 server for customer DNS, I couldn’t reach my sites and mail got goofy.
The problem turned out to be outdated DS records that lingered at Godaddy after I tried their DNSSEC product, had all sorts of problems and turned it off. DS records aren’t deleted automatically in that process — they need to be deleted manually on the Domain Details/Settings tab. Who knew? Why should I have to know?? Continue reading →
