I'm Senior Knowledge Manager at Percona, a services company specializing in the MySQL database.

I've been a software engineer since 1987, and my specialty is as an SQL maven. I also have experience programming in Java, PHP, Perl, C, JavaScript, and I have many other coding skills.

I've written a book, SQL Antipatterns: Avoiding the Pitfalls of Database Programming from Pragmatic Bookshelf, based on the most common SQL problems I've answered on Stack Overflow and other forums, mailing lists, and newsgroups over the past 15 years.

@ErikE, thanks for your support. But FWIW I consider this thread over nearly a year ago.

Well, it's not a structural problem or a design problem. Refinishing the floors fixed it. I'm sorry that this story bothers you so much.

It was a good price, and the messed up parts were basically cosmetic. It was a good house in a very good location.

And the thickness of the mold growing on top of the carpet would provide another R2!

comment What are the red streaks in my toilet occasionally?
Be careful not to mix chlorine bleach with acid, found in some toilet bowl cleansers. This mixture produces poisonous chlorine gas.
