Thanks for the suggestion. That was one of the first things I tried (according to my notes back in August). I raised a contact request and got ticket assigned (#2139). I just looked it up and there has been no response. In fact it lists at the top:
"Being Processed since 49 days and 12 hours"
I've got to imagine that the Onion.io chaps are busy.
It's no great secret what I want to chat to them about ... and I'll be very open on the notion ...
With Raspberry Pi, C.H.I.P, ESP8266 and the new ESP32 ... we are rapidly becoming awash in good single board computers of one description or another. My hobby is studying these and writing about them. I also like to make the materials available as cheaply as possible while at the same time trying to cover my own costs (time spent studying and materials to study upon). That's why I make the books available for no charge but with the notion that if one finds value within, one can donate $5 or so to the on-going maintenance.
The reality of that as a commercial venture is laughable ... all told I'm lucky if I earn enough for a large pizza in a day (and many days I'd go to bed hungry). As such I have my day job in the real-world and my passion/hobby (which I suspect many of us here have) in the evening which is tinkering and (for me) writing. My goal in wanting to chat with the staff at Onion is to see if they would be interested in making it worth my while to write the book. One possibility would be a modest contribution from them that we might consider to be a good will gesture to write the book. The book would still be delivered for free with contributions from readers if they perceive quality ... but I would open that information up to Onion and offer to pay them back for their contribution from any revenue that might accrue from the book. This would offset my fears that the demand for Omega 2 resources is too low.
So ... if we work on an assumption that if I wrote a book it would contain content folks might benefit from (and again ... that is the starting assumption) ... then if Onion "underwrote" my effort ... then if Omega and Omega 2 are successful, there will be lots of Omega and Omega 2 users ... contributions to me for the book would come in ... and that would be used to return the fronted offering from Onion. However, if Omega and Omega 2 don't draw the numbers that I fear ... then my effort would be worthwhile for my time (something like an insurance policy).
Hopefully this doesn't sound like too daft an idea. Comments pro or against are also welcome.
