Oracle & Linux: Ancient History

Hearing this week that Larry Ellison is thinking of acquiring and releasing its own version of Linux and seeing the ensuing media buzz reminded me of a different, but no simpler time: November 9, 1998. In fact, to say it reminded me is an understatement, I have a severe case of déja vu!

Quantifying Commit Time

Have you ever wondered how fast you can commit ? No matter what you do, a true commit will take time.

Inaugural post – Pythian and DBD::Oracle

Siebel Customers to Choose Between Oracle and SAP

Oracle, currently in the process of acquiring the leading CRM (“Customer Relationship Management”) vendor, Siebel, is seeing some form of competition from SAP, who is offering to US companies running Siebel, a credit of up to 75% of their existing Siebel software licensing fees toward the licensing of SAP’s comparable CRM products.
