TweetDatabases are all about I/O speed. If you believe that 20% of the data is 80% of the queries, then any database over five times RAM is too large to be fast. In most businesses data over a year old shouldn’t matter. It shouldn’t be part of the 20%. For OLTP, that’s almost true except…

Cupcakes instead of Layer Cakes and Mocks for Integration Testing
TweetAt every company I’ve ever worked at we needed more automated tests. The problem is that you can only do so much with Unit Tests in Cloud/Enterprise development. You need “integration tests”, but those become a huge pain in the ass. Some people point to “Mocks” as the answer. Except Mocks don’t seem to work.…

Mac voodoo: Always use the combo updater
TweetThis is just a piece of mac OSX voodoo: I never use Software Update for a major OS upgrade, I always use the combo installer. Even though it’s a larger download, the combo updater ends up refreshing a big hunk of your OS so any bits that have rotted get fixed. I’ve also used the…
Why I Like DB2
TweetI cannot for the life of me figure out why people use MySQL when they have DB2 to choose from. DB2 is free for 1 core and 1GB of I/O buffer and as much data as you want. 99% of the websites in the world could run just fine on free DB2. The workgroup version…
