Mainly for Yandex, I've marked all my videos
I'm doing the same for audio, which is also consistent with the
explicit flag in the podcast RSS feed.
2019-09-21: MBA Charge Profile
(This is not the right place for this note; I should probably move it.)
I set my (lid-down, sleeping) MacBook Air to charge from off-grid ~07:40Z. See extract from power management log below (see "P" values) and graph. The MBA battery was maybe a little under half full, thus needing ~25Wh to fill. See demand peaking at a little under 60W and tailing off not quite to zero over the next couple of hours. Base consumption by everything other than the MBA is about 1W. (See the first sample before MBA charging started.)
I've noted before that cutting the initial peak demand would be kinder for off-grid applications. A softer start would reduce strain on external storage and converters/inverters.

2019-09-16: Five a Day
Talking with my dad this evening, he reminded me that it took about a day for him to make five minutes' worth of finished TV way back when. Thus a week to make a half-hour nationally-networked prime-time programme.
My "rad sounds" episode took about a day (~8 hours all told) and produced about three minutes, so the same ball-park. I was doing only audio, working to purely my own agenda, etc, which all helped, I think!

Well, that was interesting.
In the latest podcast episode I got to play with Audacity a little more, learning how to insert sound clips into the speech.
Those clips were in part made by abusing
awk to generate
binary WAVE (
.wav) files, as well as resampling
input data to get the correct steady sample rate.
Yes, outputing binary using
Even though just because you can doesn't mean you should, I did!

Shockingly enough, having pushed out the third ~3-minute episode, and worked my way into the Apple and Google catalogues (and some smaller ones), I am not some kind of instant famous influencer!
I can see little evidence of the
.mp3 files being downloaded
by actual humans. (Though Google caches the audio files for its users,
so not listen would be visible to me in logs anyway.)
(I can see the
.rss file being pulled reasonably regularly,
though apparently more so by the smaller players!)
I have an idea or two for another topical episode, so I may commit to both at least one of these "Website Technicals" and a podcast episode each month. I'm guessing that the podcast episodes will have to be a lot less technical, but we'll see.
Ideas floating around in my head right now:
- I bought a Fairphone 1 in Nov 2013 (with a panic battery replacement mid 2016), and hope to upgrade to version 3 in October: is 6 years a good life for a smartphone?
- Out and about installing Radbots for our ECO3 project.
- Music (and visuals) from heating traces.
- Having another go at reducing gas use at home, using solar PV. Yes, I've been around and around this one before!
