An introduction to Lucene and how to use the API sent by Pascal (thanks for keeping me updated with good technologies bro). Lucene is a high-performance, scalable, search engine technology. This could possibly be useful for the blog projects I am involved in at the CRAFT.

We put online and roughly commented some of the map visualizations we made at the CRAFT as part of the researches on mobile technology in a formal learning environment and exploring spatial features for collaborative problem solving with locative media.


Hibernate and xDoclet

Posted: February 25th, 2004 | 1 Comment »

Pascal took some of his valuable time to explain me his use of Hibernate and xDoclet:

i use hibernate as an ORM tool. it is the bridge between my Objects and relational DB (mysql). it offers persistence for objects, as long as these objects are following some simple rules (getters, setters, … actualy you just need to write them Bean style).

hibernate creates the tables, the SQL statements (DB system dependent…just tell it you use oracle…and it will create oracle compliant SQL….at deploy time). hibernate also takes care of IDs, polymorphism and so on. just tell it to persist an object….bumm. its stored (i just signed up for my marketing career at hibernate :-) )

for hibernate to know the relations, properties, …, you need to feed it with mapping files (*.hbm.xml). writing these files by hand is a pain. thats where xDoclet comes at rescue….just add some hibernate tags to your java comments and generate everything. magic.

java source code (note the @hibernate tags in the comments):

Proximity Matters

Posted: February 16th, 2004 | No Comments »

Thomas Allen of MIT is considered on e of the progenitors of modern office design. In a ten-year study of engineering in R&D labs, Allen found that proximity matters: People interact most with those located close to them; people seated more than seventy-five feet apart rarely interact at all. Other studies found that software developers, like many creative workers, need both interaction and intense, focused concentration. When people had the “flow” of their creative work interrupted, it typically took them 20 to 30 minutes to refocus. Source: Creative Class.
