Interested in installing nginx on a Fedora system? The configuration with nginx is more complicated than Apache since it requires the setup of the nginx server and a separate daemon for running PHP. I prefer creating the daemon from scratch rather than going with the fpm route in Fedora 14 since there isn’t official support for it. I’d certainly install the fpm package once its available in Fedora.

The user load time on my server is minimally impacted with 50 clients viewing the site simultaneously.

Looking for some good plugins for your WordPress blog? Here’s a list of the top 5 essential WordPress plugins that I’ve found. These 5 plugins will help with reducing spam on your blog, improving security, adding mobile device support, blog statistics, and improving search engine visibility with your site.

1. Akismet. This is the first line of defense for spam on your blog. Its available in the base install of WordPress. All you need to do is to sign-up for the Akismet API key (free) and enter it into your WordPress configuration. It also helps the community when you tag a comment as spam.
2. Login lockdown. This prevents your blog from getting hit by sites trying to run dictionary or brute force attacks on your WordPress logins. You can configure the maximum login retries, retry time in minutes, and lockout length. Highly recommended.

If you import a post greater than 100KB, the import function to fail completely.

If you don’t have access to change the PHP server settings, simply edit the RSS file and remove the large RSS posts from the file.

If you have access to a server:

As an administrator for a WordPress MU install, I’ve been getting comments about the RSS feed in WordPress not fetching the latest feeds. The RSS feed information that appears on the page ranges from a fetch that is a few hours to a day old. I’ve confirmed this is an issue with 2.9. This is an issue for blogs that need to pull alerts from an RSS feed within a timely basis, e.g. every 10 minutes.

The workaround to this is to use the KB Advanced RSS feed plugin instead of the one that’s in WordPress.
