Was looking recent publications about Class-E amplifiers and came across this abomination.

Ugh… the fact that (for some considerable time now) udev doesn't permit RUN rules to spawn persisent processes and will track and unconditionally kill every process that got spawned by the initial helper program is such a nuisance.

All I want to do is launch the user space daemon that loads the FPGA gateware bitstream into the device and opens up a couple of unix sockets multiplexed into the different functional blocks in the gateware.

But noooo… I now have to fight adversarial API design.

Anyway, I should have bought that synthesizer keyboard a lot sooner. If I compare the crap I used to play before, or even the direct comparison of what I played just 4 weeks ago with my progress so far…

Because with this thing I just sit down, tinker with it, love exploring the sounds, and then to make it more interesting advance my playing technique.

This is how I learn… forget about those miserable keyboard lessons some 30 years ago.

I already understood this from photography, and other artistic/crafty activities. You don't really learn things, or get your exercises to stick, if you don't have fun doing it, and are fighting the process.

If you start out with photography, get a good camera, and good lenses! You can only then make the jump to lesser equipment, once you have a good understanding of how things work, and therefore can work around or even lean into detrimental constraints.

Still… it's one thing to admire a piece of kit and just buy it "because", or if you'd actually do more than just toying a bit with it and then have it collecting dust.

However, over the course of 6 years, I kept actively seeking out videos and tutorials on this synth, every 2 months or so.

So a month ago I bought it; got a refurbished unit from the manufacturer's store.

So here's my verdict:

GEAR MATTERS!

Well, and then I came across the review for a (then) newly introduced synth. Since then I've got an expert (by training) in signal processing, analog circuit design, etc.

So I then actually had thad intersection of theoretical knowledge and musical taste, that I understood what I was watching. And the whole concept of this synth (direct-digital-synthesis oscillators, going into an analog subtractive filter stage, followed by digital effects) intrigued me.

Now, my mom asked me, if I would give her my old keyboard, since now in retirement, she thought about learning to play keys.

So I instead opted to get a small controller keyboard. Akai MPK mini mk3. It's… okay I guess if you already have some proficiency or just mess with arpeggiated movements, but spanning only two octaves it's IMHO too limited for actual playing.

Anyway, starting 2020 I also watched a lot of music making YouTube.

However, most of the time with this I attempted to use it in some way for sound design; coax it into being a synth. The last thing I actually actively played a standalone keyboard was before the turn of the century.

My interest in sound design simply didn't particularly well overlap with what I could do with this thing.

Fast forward 25 years, while we were forced to keep our social distance, I started to mess with soft synths.

Back in the early 1990ies as a (very) young teenager I laid the roots for my musical tastes; thanks to the Vinyl collection of my mom (thanks). Pink Floys, Jean Michael Jarre (she got an original pressing of Oxygene), Kraftwerk, yes also Queen of course.

I kind of got interested in synthesizers, but unfortunately my mom lacked any technical knowledge. But I got a keyboard (with MIDI 🙂), based on a Yamaha wavetable chip; and I took lessons.

Filmisch extrem beeindruckend; ist ist als Stop-Motion erkennbar und doch sieht es nicht nach Stop-Motion aus. 10/10

Obwohl weit über 2 Stunden lang bleibt dennoch kaum Raum das sich die Story so richtig entfalten kann. Dementsprechend auch teilweise etwas hektisch geschnitten. 6/10

Musik ist ok, aber kein Soundtrack, den ich mir als Album kaufen würde. 6/10

Abzüge in der S(tory)-Note, weil in der Handlung die Krähen (klischeehaft) schlecht wegkommen. 4/10

As far as I am concerned, the only reasonable way to keep time on a computer is having a 256 bit high precision counter on the CPU, driven from an NCO (so that you can tune the clock to an external precision source) and a dedicated instruction to read that counter at a resolution appropriate for the task at hand.

RE: https://discuss.systems/@thalia/117498085385927493

The most annoying thing about timekeeping in computers is, that (unless we're seing 256 bit word sized architectures) you'll always need more bits to conveniently represent time, than fit in a word, but also, that time is not a static value, so you can't conveniently cache away the higher bits.

So here's the question: For the upcoming gloom-season shall I buy one of those TP-Link-Boxes and see if I can make NetBSD run on them?

4/4 poll

However, as of recently TP-Link – in Germany – is selling a consumer grade router device that's placed direct competition to the popular FRITZ!Box routers you can find in about 1/3rd of the households here.

Of course TP-Link doesn't specify on their product page, what and which amount of hardware this thing runs on. But… they do point you toward a source code download for GPL compliance, in other word, this thing definitely does run Linux.

My OS of choice would be NetBSD though…

A few years ago my prime choice as a base platform for this kind of thing would have been some PC-Engines APU board. Alas, those no longer are made.

What it comes down to is having a hardware platform – essentially a consumer grade router – with enough oomph to run the required services. It doesn't take that much, but unfortunately your average consumer router is usually under equipped on storage and RAM.

A couple of days ago I jumped into / joined a discussion about self-hosting. Specifically, that yes, people should self-host *everything*, and no, that doesn't mean that they're supposed to learn everything about it.

The idea is, that one could buy a self-hosting hub, appliance style, in the electronics store of choice, power it up, that thing asks for the name, or a backup to restore, and then does everything required. Not a new idea, see https://datenwolf.net/missing.html#5

Anyway, hardware…

Side note on encoding something like that with a lossy codec: In a practical implementation you'd high-pass filter the frequencies coing into the higher order SH terms; the narrower the beam/lobe the less directional it becomes for lower frequencies (basic diffraction physics). For practical numeric implementation you'd choose approximations of the base functions, that are quick to evaluate with a couple of bit-shifts and arithmetic (avoid LUTs where possible!) and accept the cross-talk.
