I already knew about git-achievements, but earlier this week I was showen Unit Testing Achievements. My first thought after seeing it was: “cool, I want to port that to Smolder!”. My second thought was: “hey, if we can do it for Git, and for testing, why not for Perl itself?” Surely it wouldn’t be too hard to harness its power for a little bit of fun? Indeed, it wasn’t…Have a look!

Oracle feature request #94739: CTAS optimizer statistics

en creating an index, Oracle versions 10g and above automatically compute optimizer statistics. And even before that, 9i had a COMPUTE STATISTICS clause to accomplish the same thing. Not only does it save the time and effort of running DBMS_STATS, but it also saves the disk I/O involved in such an operation, since all rows are available in the course of index creation.

Shuck & Awe #10: Hunting for Perl

In a turn of events so monumental that it can only possibly be a sign that Ragnarok is nigh upon us, an early adopter implementation of Perl 6 has been released. The number of blog entries that it generated is, as one might expect, quite massive. But most important is, the downloads — both for Unix and Windows — are available on Github. Don’t lose any time! Go, download, compile, and get a taste of what the new kid on the block has to offer.

Production Advice for Developers (3 short pieces)

I’ve spent over a decade managing various production systems. After spending so much time with systems that are mostly not working as they should, one develops certain outlook on life. Like the deep belief that the only way to keep civilization functioning is by taking backups and testing them. Recently I had few discussions with developers, and it turned out that ideas that I consider trivial can be viewed as deeply insightful by someone with different experience.

Data Warehousing Best Practices: Comparing Oracle to MySQL pt 2

This part will go over the 2nd “P”, partitioning. Learning about Oracle’s partitioning has gotten me more interested in how MySQL’s partitioning works, and I do hope that MySQL partitioning will develop to the level that Oracle partitioning does, because Oracle’s partitioning looks very nice (then again, that’s why it costs so much I guess).

Data Warehousing Best Practices: Comparing Oracle to MySQL pt 1

At Kscope this year, I attended a half day in-depth session entitled Data Warehousing Performance Best Practices, given by Maria Colgan of Oracle. These are my notes from the session, which include comparisons of how Oracle works (which Maria gave) and how MySQL works (which I researched to figure out the difference, which is why this blog post took a month after the conference to write).
