Email

There is a way to send text messages to email addresses. Here's a description of how to do it.

Phone

For those that like phones, my (landline) phone number is (805) 499-3694. If you get voice mail, please do leave a message. I will get back to you.

Note: my home phone is not capable of receiving text messages; and attempts to text to it will not be informed of this fact!

In other words: if you attempt to text me:

  1. I won't get your intended text.
  2. I won't know that I missed your intended text.
  3. You won't know that I missed your intended text.

Incidentally, I don't like cell phones because I think cell phones cause cancer, and give people a way to disturb you on their schedule rather than yours.

Also, my landline gets so many "Spam Risk" callers (showing up in the caller ID) that it's not worth the effort to attempt to answer the phone (even if we are in earshot!) if we don't know who you are (and/or we were not expecting a call from you).

(One observation about SPAM callers (BTW): they never leave a message (because they aren't legitimate); hence if the caller ID says "SPAM RISK" we deliberately let it go to voice mail.)

I have a cell phone; but it's typically for emergency outgoing calls (and similar), and it is left turned off otherwise (to avoid electromagnetic radiation).

Music

This section is for music: from theory to playing instruments (including the creation of virtual performances that never were).

Music Geeks

Music Geeks is a group I started to explore the use of technology in music.

That includes topics like:

At the next-to-last Music Geeks (Zoom) meeting, the agenda was to resolve the latency issues discovered at the last meeting.

When I shared my screen running Dorico (music notation software), my machine became sluggish.

To answer such questions Dave shared his screen to see if his machine fairs any better. It worked, albeit he had no sound for playback.

Another problem I had: the sound was terrible during playback.

Googling for this issue I found a discussion about this on a Steinberg discussion forum: how to stream Dorico over zoom using Focusrite Scarlett 2i2 4th generation interface.

Since I have exactly that model of audio inteface, I should try this. I'll need to research how to do loopback.

The aforementioned link has a link to a tutorial on how to do this.

I also found this link in YouTube: Using Dorico in Zoom. Note: this requires downloading a Zoom driver.

At the last meeting, Dave and I were both able to share Dorico while doing playback; hence we have proof of concept for both Mac and Windows.

One caveat: André was not able to see the Zoom Audio Device driver; but with his current settings optimized for music presentations, it still worked fine. We will do more experimentation with this before opening the meeting up to a wider audience. If the audience widens beyond what would make sense for a single meeting; we can apportion attendees to different weekly meetings to stager attendance.

Right now we're doing 30 minute weekly Zoom meetings to resolve these issues; but going forward, we'll probably drop back to monthly meetings.

We will watch time limits judiciously to avoid being unceremoniously dumped by Zoom at the 40 minute time limit.

Origami

This section is for origami related topics; including diagrams, links of interest, etc..

PCOC (Pacific Coast Origami Conference) 2025 is coming up this Fall (October 30 to 3 November).

Here is my gallery from PCOC 2017.

Pixel unit origami

I host a pixel unit origami zoom class via Origami USA entitled Origami to the Max: pixel units. (The word Max in the name name is a pun on the (now deceased) inventor of pixel units Max Hulme.) This class takes place every first Thursday at 1 p.m. PST.

The next pixel unit origami class will be posted soon on the Origami USA calendar.

Topics will include:

Lately, I have been experimenting with using SVG (scalable vector graphics) in conjunction with HTML 5 and CSS 3 to diagram origami.

Since you can include raster images in SVG, this allows photos of origami to be superimposed with vector graphics for diagramming. You could even create vectors on top of an image, and then remove the image (thereby creating a vector facsimile of the raster image). One obvious advantage of vectors is that they scale in a lossless fashion.

Here is an example; just enough to show promise for this approach.
