I had just been looking for a windirstat like tool for linux the other day.

What I really also want is a way to do an offline index that this reads ... I ended up using duc. Maybe I will fork and add it!

thanks for sharing!

Remember the printer in Office Space?

My mnemonic is “In Essence” and “for EGsample”

soft keyword for anyone not familiar like I was ...

"A new soft keyword lazy is added. A soft keyword is a context-sensitive keyword that only has special meaning in specific grammatical contexts; elsewhere it can be used as a regular identifier (e.g., as a variable name). The lazy keyword only has special meaning when it appears before import statements..."

I've been using btrfs for maybe 10 years now? -- on a single Linux home NAS. I use it in a raid1c3 config (I used to do c2). raid1cN is mirroring with N copies. I have compression on. I use snapshots rarely.

I've had a few issues, but no data loss:

* Early versions of btrfs had an issue where you'd run out of metadata space (if I recall). You had to rebalance and sometimes add some temporary space do that.

* One of my filesystems wasn't optimally aligned because btrfs didn't do that automatically (or something like that -- this was a long time ago.) A very very minor issue.

* Corruption (but no data loss, so I'm not sure it's corruption per se...) during a device replacement.

This last one caused no data loss, but a lot of error messages. I started a logical device removal, removed the device physically, rebooted, and then accidentally readded the physical device while it was still removing it logically. It was not happy. I physically removed the device again, finished the logical remove, and did a scrub and the fsck equivalent. No errors.

I think that's a testament to its resiliency, but also a testament how you can shoot yourself in the foot.

I've never used RAID5/6 on btrfs and don't plan to -- partly because of the scary words around it, but I also assume the rebuild time is longer.

I think of this as fail fast. Fail immediately so its easy to root cause the failure and not have it be hidden and cause more obscure side effects later.

How can we determine if an index can be satisfied by a constraint index?

For example, does the FK need to be the first field in a unique together?

I hope to see qualified immunity eventually re-evaluated by the courts due to this...
