What doesn't need defragmentation? Linux or the ext2 ext3 FS? The other answers are good but leave out one important bit: All of the filesystems: ext2/3/4 and NTFS will fragment files quite a lot when low on disk space. If you want to prevent fragmentation, don't allow your filesystem use to exceed 90%. |

What happens if a cron script tries to copy a directory at the same time as another process is writing to it? You do not need a locking scheme. You need an atomic update scheme. What I did for a similar problem is to copy new files into a tmp subdirectory then move them into place after the copy is complete. If you copy subdirectories then use a directory at the same level. Just make sure it is on the same filesystem. |

pv for directory copy @StephaneChazelas: Because a pipe's buffer is only 8KB. A program like rsync might want to use a much larger internal buffer. |

How can I switch window managers in Gnome 3? This does not actually work because GDM seems to only detect full desktop environments, not window managers. |

Writing a Kernel from scratch A programmer probably has to be a bit crazy to write an operating system at all. |

Accidently created a file called -X, how can I delete it? Good answer, but readers should note that -- is only supported by the GNU tools. Don't expect it to work on BSD. |

Why does Linux scale so well to different hardware platforms? @Billy: It seems to me that if your kernel can be turned into a micro-kernel just by changing a few options and rebuilding, then it's something other than monolithic even if the most often used binary builds put everything in kernel address space. |

Why does Linux scale so well to different hardware platforms? And the small system and huge system definitions keep shifting all the time, so it's good kludges have been avoided. The multicore smart phones can now benefit from all the super-computer work done years ago. |

Why does Linux scale so well to different hardware platforms? @Billy: Windows NT is technically a hybrid kernel. I believe Microsoft still maintains the subsystems using message passing and keeps the ability to move pieces into user-space as desired. They did this with the graphics system in Vista: it's now in user-space after having been kernel-space since NT 4.0 |

Linux boot loaders supporting full disk encryption? @Grodriguez: Your requirement makes no sense. Is your requirement met when using a virtual machine inside another OS? If so, then boot OS one, decrypt the drive and launch the VM. |
