apt-get update directly after boot results in many Ign and Hit, resulting in 'no installation candidate' errors Argh, of course. I now see my failed update is fetching from repos like "archive.ubuntu.com"; that aren't even in my source.list (once I check on it). Thanks! |

How does changing a GPG encryption key's passphrase work? Duh, thanks both of you. Don't know why I didn't realize that. |

Can SQLite be used with GlusterFS? More to add: just ran your test that doesn't use explicit locks concurrently on a single NFS client, and locally on the NFS server. The NFS client fails on "count.sql" after ~30 runs. |

Can SQLite be used with GlusterFS? Noticed your edit. This latest version with explicit locking works for me with three clients/one server. In the previous version I get frequent "unable to open database file" errors, any idea why? The usual explanation seems to be improper permissions of the parent directory, but not here. |

Do I need to run ntpd in my EC2 instance? I just noticed a several minute drift in one of my servers in which /sys/devices/system/clocksource/clocksource0/current_clocksource is set to xen as well |

Using NOPASSWD for specific commands in sudoers file, PASSWD for all others I get sudo: unknown defaults entry nopasswd'` when running commands in the list. I'll play with it and see if I can figure out what it's doing. |

Re-gaining root access to an EC2 EBS-boot image Haven't had the opportunity to test this, but marked as answered since I assume it will work. Thanks. |

Re-gaining root access to an EC2 EBS-boot image Thanks for the answer. I hadn't considered that maybe there would be no password set. Unfortunately passwd asks for my current password. I think the 'ubuntu' account may have been created with $ adduser --disabled-password ubuntu. Any other ideas? |

How can I reset the permissions of /bin /boot /etc and /dev to orignal owner, Ubuntu? I wasn't really clear in my answer, but the output of the command I displayed above shows in order: filename, user, group, for all the files not owned by root:root on my debian system. I imagine your system uses many, if not all of the same permissions. I don't know if there is a way to restore permissions e.g. with apt |

How can I run a job when the server load is low? Thanks, batch looks great. I decided to go with a homebrew solution since I realized I am more interested in disk IO. |

What techniques do you use to design and scale a web app horizontally (in EC2)? Thanks, I was hoping for more general discussion about this topic so I didn't include much info about our app. But since no one seems interested... we are a google-docs-style application and (at the moment) are storing user data in individual directories, each with an sqlite DB. We do this because our system will be both on and offline, and users can down/upload their data in this form. |

AWS S3 Bucket Backups if you're using a tool like s3cmd, it's no harder than it is to delete an entire directory tree with rm -rf |
