Escape for Developers
No, not sneaking out, Office Space style, on Friday afternoon, but escaping escape
characters on the Web. You'll see what I mean in this blog entry at Aut Disce, Aut Discede.
Injections and mod_security
On a related note, I haven't nagged you about SQL injection in a month or more. Time's up! Tyler Muth covers it, along with some other related topics of interest, in this posting.
Browsing the Stacks
There are open libraries (like the typical one in your town) and then there are the 'closed stack' variety, like the Library of Congress. In a closed stack library you find the book you want in a catalog, then order it through a desk. Unseen minions then bring up your book from the great labyrinth of books. Such is Oracle. You can't just go into memory and find out what you want. You have to call on one of our processes to go into the SGA and bring back the data, right? Well, no, not always. You can dive into that memory stack and snatch books off the tray before they reach the readers (well, at least copy them, not remove them, if you want to avoid a crash). Many high-end products over the years have used SGA mining to get advanced performance information, for instance, with near-zero impact on the system. Tanel Poder, a veteran stack spelunker, brings us the latest of his series (fifth installment) on: Advanced Oracle Troubleshooting Guide, Part 5: Sampling V$ stuff with WaitPro.
Let out that inner geek and give it a look!
