  • This is madness, but since this is a hobby project and not a production server, there is a way:

    • Shrink the filesystems on the existing disks to free up as much space as possible, and shrink their partitions.
    • Add a new partition to each of the three disks, and make a RAID5 volume from those partitions.
    • Move as many files as possible to the new RAID5 volume to free up space in the old filesystems.
    • Shrink the old filesystems/partitions again.
    • Expand each RAID component partition one at a time by removing it from the array, resizing it into the empty space, and re-adding it to the array, giving plenty of time for the array to rebuild.
    • Move files, shrink the old partitions, and expand the new array partitions as many times as needed until all the files are moved.

    This could take several days to accomplish, because of the RAID5 rebuild times. The less free space, the more iterations and the longer it will take.







  • This just sounds like a bad idea, a solution in search of a problem. Sure, sudo is a setuid binary, but it’s a fairly simple program, and at some point, you have to trust the code. It’s also a very fundamental piece of the system that you want to always work, even (especially!) when other things get borked. The brief description of run0 already has too many potential points of failure.









  • You’re really missing out! In my opinion, PBR is the best of the “cheap and shitty” tier of mass-produced beer that rednecks and poor college students drink to get smashed. It’s not good, exactly, but somehow nostalgic to me for drinking around a campfire. The U.S. has plenty of mass-produced beer that’s still mediocre, but better than PBR, and some that’s even pretty decent. It’s in the craft breweries that you’ll find the really great American beer, though.



  • In addition to philosophical questions, the Trolley Problem is also a good tool in psychology to study human ethical reasoning. It turns out that people’s intuitive responses vary quite a lot based on details that seem like they shouldn’t make a difference. If I’m remembering correctly, I believe that a lot more people say that they would divert the trolley if they imagine that they were observing the situation from a gantry high above the tracks, rather than in close proximity to the person who would be killed thereby.
