Oracle DB Express

Posted by F Tue, 01 Nov 2005 21:45:00 GMT

I just realized about an interesting move from Oracle. They released a Beta version of their new Oracle Database 10g Express Edition.

This Express edition is free of charge. It is free not only for production use, but also for distribution.

These are the limitations it has:

• It restricts itself to use only one CPU
• Only one server and database instance (SID) per installation
• Database size limit of 4GB

Looks like a good deal for ISVs, developers and small shops. It’s a good way for getting more mind-share among small software companies and younger/future developers.

I tried it on my Linux laptop and got it up and running in a couple of minutes. The Express name does not make it any lighter though: it still consumes a good chunk of RAM, and the database instance allocates 1GB of disk. So I’ll stick to PostgreSQL for powering this blog :-).

Errata for "Holub on Patterns"

Posted by F Sun, 16 Oct 2005 01:51:00 GMT

Months ago, I was looking for a book on Design Patterns. I already own the great classic GoF and a few more, but I was looking for a more practical, real-world exposition of the classic Patterns. I wanted a book I could recommend to new developers, so they could really learn how to apply the concepts.

I came across Holub On Patterns. I liked it, but I was disappointed with the editorial quality of the book.

I found a long list of errors. Some of them are minor, but still may confuse readers, specially those new to the topic.
