WordPress and dubious themes

If you are like me and deal with a lot of WordPress themes chances are that you have encountered several themes that contain something like:
eval(base64_decode('ZnVuY3Rpb24gY2hlY2tfdGhlbWVfaGVhZGV
yKCkgeyBpZiAoIShmdW5jdGlvbl9leGlzdHMoImZ1bmN0aW9uc19maWxlX2V4
aXN0cyIpICYmIGZ1bmN0aW9uX2V4aXN0cygidGhlbWVfZm9vdGVyX3QiKSkpI
HsgdGhlbWVfdXNhZ2VfbWVzc2FnZSgpOyBkaWU7IH0gfQ=='))
Now, all the people, or at least most of them would advice not to use such things on your WordPress and probably they are right. But if you are a curios person like me you have to know what that long string means.
function check_theme_header() { if (!(function_exists("functions_file_exists") && function_exists("theme_footer_t"))) { theme_usage_message(); die; } }
Meh, not a big deal. Someone is very obsessed about his links in the footer of your WordPress theme. He want's to make sure you keep his precious links in place. Whatever!
I find this very rude however and a headache for anyone that installs wordpress themes, especially free ones. A simple "Please keep the footer intact" would do better. People are going to replace the footer anyway if that's what they desire. No one wants some strange text that he doesn't know what's doing on his server.

And because I like to have at least one useful thing in my posts here is a link to an online decoder, the same I have used to decode the example: http://www.motobit.com/util/base64-decoder-encoder.asp

To quickly find such precious bits of information you can run something like:
grep "eval(base64_decode" -r /path/to/some/dir 2>/dev/null

LE: An so I discover another bug in my blogger theme ...

New Template for Blog

I have decided that is time to change the look of my blog so today I've searched for blogger templates. I found relatively quickly a good one called "simpress". It's green, it's fresh and I like it a lot. Unfortunately I still have a ton of things to adjust to make it work as it should.

Not working now:
-date is not displayed for each post in the upper left box
-labels don't show the number of articles they are used in(well technically they are there in the output, just not visible)
-blog archives section doesn't show the number of posts for each month(same problem as above)
-edit or remove contact and about me. how do I link About me to my Blogger profile?
-dont try google search, it will mess things up, need to find a way to fix it
-firefox is eating 800MB of RAM on Windows 7. bleah I need to restart the PC, see you later all!
