I was at the ESUG conference in Amsterdam and found two nice books, which may be interested to Smalltalkers …
* Hashing in Smalltalk – Theory and Practice by Andres Valloud
This book introduces into the problems of Hashing technology, a technology lots of programs depends on.
* Squeak by Example by Black, Ducasse, Nierstasz, Pollet
Introduction into programming in Smalltalk in Squeak and usage of the IDE and general programming concept.
Another book I found at Amazon:
* An introduction to Seaside – Developing Web Applications with Squeak and Smalltalk
by Perscheid, Tibbe, Beck, Berger, Osburg, Eastman, Haupt and Hirschfeld
An introduction into Seaside and in technologies around Seaside (persistency and all that).
It is often said, that the appearances of books about a topic shows a general increase of interest in this topic … perhaps we may hope, that Smalltalk will get increased publicity …
