Ask @windyoona:

why does it seem like you love to shared, but not over shared your work...Is it due to being fastly put together concepts or prototype, and or you dont want others to steal you work or credit? It almost comes off as mysterious as if a glimpse of your thoughts without really getting deep into it

J.D. ----Dernyn
That's a good point, maybe you're onto something here. This is how I see it: I try to write as concisely as possible, without obscuring too much relevant information however. Those interested in the topic will hopefully still be able to grasp my point, and no-one will get at tl;dr moment.
A few of my blog posts, for example the microwave dish direction detector, were left as mere concepts and so I never elaborated on them. Also, I'm not very keen on releasing source code for a hobby project - the code was usually written in a haste, would be very non-portable, and thus I would have to turn down many requests for support due to lack of time. So I just write a blog post in hopes of being able to share the fun part of my adventure.
I've been thinking of possibly making more educational posts in the future, and I do have some as drafts. However, I'm a bit more perfectionist about them, as I see teaching as quite a big responsibility.

No, coffee is my fuel. But I love to have a cup of good tea in quiet with tea enthusiast friends.

Hi Oona, thanks for your blog and correspondence over here :) Are you familiar with the Duga radar systems ("Russian Woodpecker"), relics from cold war, but still an interesting concept. 10MW installation in Ukraine, another in Far East, used as OTH-radars. Interesting piece of history ?

Juha Maenpaa
I've heard about it, yes. Indeed an interesting piece of history. I'm glad there are still some mystery stations left for us.

Do cars need artificial increment in sound production to be less of a danger or is it better to make them quiet as possible so people and other animals don't get annoyed by them? Cause they are making me crazy with these low frequencies and effing doors banging :( . *sensibility is useless in a city

Personally I'd prefer quiet cars, but I live in a place where traffic lights are generally obeyed.
I think some of the sounds may have more to do with making the car feel expensive and powerful.

Do you like dank memes? :^) also, what do you think about ylilauta and Spurdo Spärde? Are they important components for the outreach and radiance of the spread of the Finnish Internet culture?

I'm mostly unfamiliar with the scene and its terminology. But STP & sakolut used to appeal to my sense of humor, if that's relevant, and I still have a well-kept sakolut collection. Ylilauta is, afaik, a birthplace of higher culture.

How do you decode stuff generated by this encoder? (Korg says it's "QAM") https://github.com/korginc/volcasample/blob/master/syro/korg_syro_func.c Is it decodable with gnuradio?

Yes, there are Gnuradio modules for decoding QAM, though it's just a blanket term for a number of modulations, both analog and digital.
Based on reading the code, it seems that KORG SYRO encodes 3 bits at a time into a symbol. The leftmost 2 bits set the phase angle of the symbol (the output sinusoid) to one of 4 states; and the last bit sets the ampitude, or volume, of the sinusoid to one of 2 possible states. On higher levels it also employs error detection and correction.
Decoding would amount to mapping the amplitude and phase angle back to a stream of bits, and also checking the CRC for errors.

Oona I would like to thank you for your answers and video I have watched it twice now and it is starting to bring some understanding to the whole concept. I spent a week in a meditation retreat the doctor there spoke of the Hopi tribe in Arizona very interesting lecture I have 38 years meditating.

We are always taught in school there is a beginning and an end I finally had a professor who stated take that theory and scrap it. Think of time space as no start and no end a continuous run. My mind has a hard time getting around that concept.

I also struggle with this question. And so does current science, I think. So I only have more questions as an answer.
Is time eternal or phenomenal? Was time created in the Big Bang? What's the Big Bang anyway? What happened before it and what caused it? Was it some kind of a "singularity" where no physical laws even applied? If there was no time and so nothing caused it, then why did it happen? Is "why" even a meaningful question, if there was no time and hence no causality?
Maybe time is just another dimension of spacetime, part of its geometry, like Einstein and his contemporaries said. But then why does it seem to be a one-way street, unlike the spatial dimensions? Does this mean time is also finite, unlike the infinite space spanned by the three spatial dimensions? Leonard Susskind once gave a lecture on the arrow of time, it might interest you: https://www.youtube.com/watch?v=jhnKBKZvb_U

So in the movie Contact Jodie Foster was only gone for a few seconds until the drop from what I remember. Why do you think so long where she was or was she somewhere it always baffled me. VA3MQ

A few seconds - from the perspective of the spectators.
If Lorentzian traversable wormholes exist, they would allow travel between two points in spacetime. Indeed, in the movie version, Ellie described the phenomenon as a "wormhole", so they certainly seem to exist in the Contact universe.
The wormhole appeared to take her over a very long distance in space and then back, also sending her back in time to the moment of departure. It does seem to be possible to convert a traversable wormhole into a time machine (Morris etc 1988: "Wormholes, Time Machines, and the Weak Energy Condition", in Phys Rev Lett). After that it would be possible to use the wormhole to travel back to the time of this conversion, as if no time had passed.
How could such a wormhole be created on Earth in the first place? The answer was probably in the blueprint of the unexplainable machine.
The original novel elaborated on the story of the machine and Ellie's experience during the journey. I think I need to read it again.

It depends on what we mean. I don't think mankind will be free of all violence and wrongdoing some day. There seems to be something inherently tempting about gaining power over and inflicting harm upon others, be it other people or nature.

This audio file is being tossed around at work. As far as we've figured out, it's likely some sort of modulated data, though we have no idea (it very well could be a troll). Feel free to have a look if you would like. http://u.pomf.io/eljvgw.ogg

How did you become interested in Biosciences? It seems a sharp divergence from your interest in signals and electronics. Have you found any interesting interfaces between the two?

John Shade
It was one of those special interests that I contracted from a friend I liked a lot. This was in ninth grade or so. Biology is full of signals, from circadian rhythms to neural impulses and bird songs and doppler sonars, so it has never ceased to interest me. The details and perhaps even the big picture of sound processing in the brain is still a scientific mystery, for example. But I also somehow enjoy the endless amount of information to be learned for no immediately apparent use, like being able to identify hundreds of different plants or insects.

Name three good books to read!

Obviously this will be biased toward books I've read and liked myself.
1. My favorite in sci-fi is still Contact by Carl Sagan (the 1997 movie told a very different story, on purpose, even though they share many of the characters)
2. If you're interested in how oscillation-based signals work, The Scientist and Engineer's Guide to Digital Signal Processing will be useful.
3. The declassified U.S. army field manual Basic Cryptanalysis (FM 34-40-2).
