First comment about the books

For some reason I went to check on the books at Lulu, and I found somebody left the following anonymous comment.

It has been a long time since I've learned so much from a book.

His revelation on how to avoid ifTrue:ifFalse: is superb. I've also instantly adopted his use of SUnit for domain object validation. Very, very good

I am very happy that the writing effort has met this kind of appraisal, and that the material is useful as judged by actual readers. Thank you so very much, anonymous reviewer. I really appreciate you taking the time to share how the book was received.

Congraulations Andres!

Which book was that comment written about? Can you place a URL to the Lulu page which lists you book?

Andres said...

The comment was with regards to the mentoring course book. The URLs to the book are on the right sidebar under "Books available".

I've bought the Hashing book and have
nearly finished it. I am
recommending it to other staff in the
department and to any students who
have the misfortune to be in my
class.

Three things.
- The book really needed references
and an index. I keep trying to
find stuff I've seen and can't.
- Is the Hash Analysis Tool
available? It wasn't clear to me
how it chooses the primes used.
- Just today on the SWI Prolog
mailing list, they've changed the
term hashing algorithm to use
MurmurHashNeutral2, and amongst
other things, the hash of a small
integer is not itself.

Oh, and did I say how much I liked
the book? I've NEEDED this!

Richard,

Thank you for your kind comments. I am happy that what I wrote is helpful to others.

> The book really needed references

While books are referenced, a large amount of stuff came from Mr. Google.

> and an index. I keep trying to find stuff I've seen and can't.

What kind of things were you looking for?

> Is the Hash Analysis Tool
available? It wasn't clear to me how it chooses the primes used.

Yes. Go to the public Store repository and get bundle [Hash Analysis Tool] (the answer to one of the exercises has the link too).

> Just today on the SWI Prolog
mailing list, they've changed the term hashing algorithm to use MurmurHashNeutral2, and amongst other things, the hash of a small integer is not itself.

I understand, but I also think that ^self is essentially just as good in the majority of cases. When it's not, then chances are assumptions about the data can be made which can provide a more efficient, high quality hash.

Richard,

Check out the book introduction. There is an email address for book feedback. Feel free to send further information to me that way. Also, if you do that I will be able to answer to you directly :).

Andres.
