I want to publish a technical book. Anyone can share his publishing experience?

Thank you Rami. I contacted him. Let's see...

Thank you Rami.
Bad idea, he just want to be a co-author.

Thank you Larry. What I am interested in was the publishing process not why or how to write a book. I wrote few books 40 years ago about programming in c/c++ and I am aware how hard is to write something good and new. However, it is also rewarding. I am not doing it for money but to share my mistakes in the hope that other will do their own rather than reinventing the wheel.
I have a series of webinars and I am asked often "where we can read more about this"?. Most of what I present are original ideas based on my experience, that were not published by someone else or by me.

I am looking for something else than self publishing or to pay 10,000$ to a ghost writing company.

Thank you.

They ask for at least $10,000. That's not really what I'm looking for :).

Hi Stelian. First, thanks for your great video series. To answer your question I published a book via McGraw-Hill-Osborne in 2004. A lot has probably changed since then.
1) The publisher contacted me. For that reason I was able to negotiate an advance and get my name on the cover. And a whopping marketing budget of $500.
2) I submitted an H1&H2 outline using an MS Word template.
3) We negotiated over the content briefly.
4) I submitted a detailed outline H1, H2, H3 and paragraph summary.
5) They paid the first third of the advance.
6) I wrote 1/2 the book and used Visio to create illustrations.
7) They paid the second installment.
8) I finished the book.
9) We reviewed edits from the copy editor.
10) Book was published and I was paid the final third.
Lessons Learned
1) The book sold poorly so the only money I saw was from the advance.
2) The experience was stressful and caused me sleepless nights.
3) My ROI (payment/time) was far less than minimum wage.
I would not do it again unless I was paid a huge advance.
My editor told me that less than half of all book contracts are fulfilled by the authors.

Marcus, thank you for the references but I am not interested in links to agencies where I should pay a lot of money. I was looking for advice from someone who published a book as a hobby.

Thank you Andrew. That's closer to what I am looking for but I was aware of self publishing options. I thought that there are other ways.
