QuoteOriginally posted by: finanzmasterI am not a core developer of QuantLib but I have a long experience with itimo contribute some useful lines of code (or did you ?) before writing a book about ite.g. what about this HPSn model, did you actually implement this ?

QuoteOriginally posted by: pcaspersimo contribute some useful lines of code before writing a book about itUnfortunately I am pretty short of time, so either contribute code or write book, but not together.Imo, a book would also be better for community, since there are enough developers but noone has written a book so far.QuoteOriginally posted by: pcasperse.g. what about this HPSn model, did you actually implement this ?Only a quick and dirty draft, which is not worth checking-in in repository.

QuoteOriginally posted by: HansiAlternative and interesting view on the topic: http://blog.plover.com/2014/12/01/ I tried this way but got disapointed. In particular, my notes on measure theory and LIBOR tutorial got very positive feedback from peers and are still available on web for free: http://www.yetanotherquant.de/#MeasureT ... dfEveryday I get several downloads but very few people even said "thank you".In context of QuantLib, Luigi confronts the same problem: "I see thousands of people subscribed to the mailing list, with many subscribers from big name institutions, and I see thousands of downloads every time we put out a new release but people doesn't tell, and there's just not that much data around on actual practical applications, or whether people use it in production" (http://www.moneyscience.com/pg/blog/Adm ... i-ballabio)On the other hand, I am quite successful with my first printed book: https://www.createspace.com/4983811On average, one copy is sold every (business) day, which is not bad for a hardly known author.Surprisingly, I have much more feedback to it than to the stuff I let download free of charge.And the most interesting: "As an author, you owe it to yourself to make your book available to as many people as possible" (this is from Hansi's link). I think, if I had made my book free, it would be just ignored. But making it cheaper than 90% of similar books I (undeliberately) created an incentive to get it.By "undeliberately" I mean that I set a low price not to make dumping but because my book can really help (retail) investors to avoid unrealistic expectation and severe losses. So I am pleased to do a socially good deal, so to say.But it will not be the case with QuantLib book. QuantLib is for financiers, who [should] have money! Even "poor" students pay thousands of bucks every year for tuition fees.

Almost no one makes proper money from finance books, they are done for the glory you say you don't want.Sure, Paul W.and Hull do rather well, but the reality is that $20K is doing very well for yourself.My wife wrote such a good book on pensions that the Pensions Management Institute gave her a medal.It paid for a holiday.http://www.jordanpublishing.co.uk/pract ... lvency-You write a book because you want to write it.The only financial benefit is that if it is a good book then your employment prospects go up rather nicely.

QuoteThough I do not expect to earn much with this book, I am not going to do it "just for glory".What's the compelling reason for writing such a book?

QuoteOriginally posted by: CuchulainnWhat's the compelling reason for writing such a book?$, ? and £But also "learning by teaching" I mean the following: when I explain some stuff to someone, I myself, usually understand this stuff much better.I have already mentioned that I had very positive feedback to my LIBOR model tutorial (see attachment). And as I wrote it, I myself have learnt a lot.QuoteOriginally posted by: DominicConnor but the reality is that $20K is doing very well for yourself.I will be quite happy with $20K (and find it realistic: even if I make $20 per copy I need to sell "just" 1000 copies).QuoteOriginally posted by: DominicConnorThe only financial benefit is that if it is a good book then your employment prospects go up rather nicely.Sorry, not in Germany. In Germany it is pretty scheißegal for them what one has written.Though the fact "a guy has published a book" usually matters. But I already have one www.amazon.com/dp/3000465200

>if.>And you wont'I will at least try! Yes, after numerious discussions here, on QN and LinkedIN I see there is a group of seriously interested.Not very big group but I hope - if I do a good job - this group will further recommend my book.At least it is the case with my "Knowledge rather than hope".You have to pay>printerNot me, endbuyer has to. $20 is not the end price but my (minimal) target royalty.I will decide about price later, depending on the content quality (on which I let judge some peers).But - contrary to my "Knowledge rather than hope" it will not be cheap (ok, "poor" students will get a discount ). >technical reviewerI have enough volunteers that will do it for a copy with autogramm>layout artist (don't to it yourself )I will, since I am going to sell the content, not cover >them copy editorsCrowdsourcing will help>the German taxman (who takes 50%)"only" about 30%. But he deserves it.

So, as I already said, I will write it!I do not know when I complete it, but based on experience with my previous book, it will take 6 months or more.Many thanks to everyone, who participated in discussion.Peer reviews are very welcome, of course all them will get a free copy with autogramm

Quote>layout artist (don't to it yourself )I will, since I am going to sell the content, not cover I think you have missed my point. If the aesthetics are not important, then you can make a pdf, print and staple it

QuoteOriginally posted by: CuchulainnI think you have missed my point. I did, though probably expressed myself unclear.Aesthetics is important but not as important as content, at least in our case.Since I have very limited resources I am going to sacrifice non-essential in favour of lower price. QuoteOriginally posted by: CuchulainnIf the aesthetics are not important, then you can make a pdf, print and staple it That's what I did as I was a poor student. But I was really poor (and it was the main reason why I made my MFE in Germany, where one pays virtually no tuition fees (and that's why I say the German taxman deserves what he demands))

QuoteAesthetics is important but not as important as content, at least in our case.Are people rational?
