Running compiled code sh: [10665: 4] tcsetattr: Invalid argument error
Compiling exploit and getting the sh: [10665: 4] tcsetattr: Invalid argument error? It helps to compile on a similar box. Find what linux runs your same kernel version+arch and compile there. Centos 4.4 is a cool one for kernel 2.6.9. That is all.

Thunderbird hidden option: sync all subfolders
I have a nice procmail setup, but thunderbird by default does not show/update the subfolders: Open the Config Editor (Hamburger menu (top right) –> Preferences –> Preferences -> Advanced –> General -> Config Editor), and change the mail.server.default.check_all_folders_for_new setting to true. It’s like about:config for thunderbird :)
