How to mark certain C code to be packed and inserted in an ELF section

Oct 19th

I am working on improving performance of my user space application in Linux. The frequently executed code is distributed across lots of files. I would like to mark certain portion of code in all files to be together without modifying or moving the code physically. In otherwords, I want all the CPU instructions of frequently executed path to be together. Is there a way to mark the code for a specific ELF section. Later once it is done, I may chose to lock the code present in this section on the CPU cache.

I see trackbacks coming from lot of websites to my wordpress blog. Is it good idea to approve the trackbacks? Does it affect my page rank ?

Sometimes I see no link to my site in the actual external page that generated trackback to my site.. Is this some kind of spam?

I want to have an RSS reader icon on my GNOME panel so that I can read RSS feeds right on my desktop. By the way I use Fedora. It would be great if the applet shows a notification (at right-bottom corner) whenever it sees a new message in the RSS feed.

I run a wordpress blog of my own and would like the blog users to do typical tasks like logging in, logging out, quick posting, rating etc from the fonrt-end itself without having to view the back-end interface. I don’t want the users to see a completely different back-end screen which doesn’t match with the original site content.

Is there a plugin that is already deployed by many wordpress bloggers online? Even the commercial ones also can do.
