Win32 Is the Only Stable ABI on Linux?
In the ELF format there are two ways of providing a hash table of symbols. DT_HASH and DT_GNU_HASH . The first one is part of SYSV generic ABI and is well documented and marked as mandatory. DT_GNU_HASH is a newer, smaller, and faster replacement that is not documented , implemented in a few places (Glibc, GNU ld…

Please Use ZFS with ECC Memory (2014)
In this blogpost I argue why it's strongly recommended to use ZFS with ECC memory when building a NAS. I would argue that if you do not use ECC memory, it's reasonable to also forgo on ZFS altogether and use any (legacy) file system that suits your needs.
