]]> Comment on Airbus A330 Unsafe to Fly by Jim Reilly http://www.jebriggs.com/blog/2009/06/airbus-a330-unsafe-to-fly/comment-page-1/#comment-27186 Jim Reilly Fri, 30 Jul 2010 23:32:37 +0000 http://www.jebriggs.com/blog/?p=885#comment-27186 The Airbus, in my opinion, should never have been certified. It is not a very well-kept secret that one of the Airbus's flown by Jetblue is called "Satan's Kitten" by the pilots, because the computer has almost caused a fatal incident on at least three flights. The Airbus is not structurally safe. To lighten weight the major parts of the airframe have been diminished. The computer avoids stress by restricting angle of bank and movement of the controls. When the structures are stressed they tend to disintegrate as in the case of the Airbus that lost it's tail when leaving Kennedy. Because the parts are assembled in many countries quality control is lacking. The wiring harnesses on different production runs have the same color in the harness leading to a different electrical connection. The computer system, without which the aircraft cannot fly, is not hardened. It can be completely shut down by an electromagnetic pulse from a terrorist device and it takes eight minutes for the computer to reboot, during which time the pilot has no control of the flight surfaces. If it ain't Boeing, I ain't going. The Airbus, in my opinion, should never have been certified.

MariaDB does not have "All of the core developers". Optimizer? Yes, but that is about it. They have none of the replication developers, connector, etc.. They have a great group of people, but they have just a tiny fraction of the folks who ever worked on MySQL. Most of them are still at Oracle. Here is a breakdown I did a while ago: http://krow.livejournal.com/687521.html Cheers, -Brian Hi!

]]> Comment on Recommended Wordpress MySQL Permissions by Sean DB Web Dev http://www.jebriggs.com/blog/2009/09/recommended-wordpress-mysql-permissions/comment-page-1/#comment-27021 Sean DB Web Dev Wed, 21 Apr 2010 13:49:57 +0000 http://www.jebriggs.com/blog/2009/09/recommended-wordpress-mysql-permissions/#comment-27021 James, good suggestion. I personally didn't like the idea of granting all permissions when it really only needs the 4 you mentioned. That's how I came across your post since I wanted to give it as limited permission as necessary. But I also see a problem with leaving only those 4 permission for a client's Wordpress. Create and Alter are likely to be used in Wordpress upgrade as well as some of the install/upgrades that these plugins that create their own data types and tables. Uninstallations of those above mentioned plugins will require Drop access but that can be manually done with PHPMyAdmin for most users. For letting clients upgrade their own Wordpress blogs, I would also not recommending chown root the Wordpress folder. Updates could fail mid way which could be a mess to clean up. You have folders in there that have files that need to be updated. Themes and Uploads, for example. James, good suggestion.
