On: It is not a compiler error (2017)

[tomcam]

My worst slowdown ever was when a compiler failed because a bit had flipped somehow. After a month and a half I finally reinstalled it and everything worked perfectly.

That sucks, but feels good to have solved it.

This is why it is important to have portable build environments. And ECC and checksumming file systems.

Do macbooks have that? What is the best checksumming file system I could use on mainstream linux?

[actionfromafar → 0x1ceb00da]

Only ones I know of are ZFS and BTRFS.

However, duckling the web got this workaround for EXT4:

i.e. use device mapping or LVM setup to do the data integrity check at the block level, under the filesystem.

1. No, Macs don't have ECC to my knowledge

2. ZFS if supported by your distro, btrfs otherwise
