Video: Take your loop mounts to the next level with nbdkit

Loop mounting is popular, but very limited in what it can do on Linux. I gave a talk at FOSDEM on Saturday entitled Better loop mounts with NBD: Take your loop mounts to the next level with nbdkit, and it’s online already!

Download the WebM format or MP4 format files directly.

Also I did subtitles! Download the subtitles directly here. (The subs only cover the first 30 minutes of the talk, not the Summary and Q&A.)

There are a few small problems and corrections:

  1. There’s a part of the talk where I refer to the light blue trimmed blocks. Unfortunately the video feed didn’t capture that, so the light blue looks like white. If you really want to see that then go look at the video in my earlier post.
  2. During the Q&A I mentioned that we could support writing to xz files. This is true, sort of, but I forgot that there’s a problem: nbdkit doesn’t support file resizing (and I believe that’s even experimental in the NBD protocol), so someone would have to add that first. There are other serious down-sides to implementing writable XZ, I doubt it could ever be fast.

For subtitles I used gaupol which is actually quite nice, although subtitling is inherently slow and tedious. It took me a good 4 hours to subtitle 30 minutes of video.
