Re: What are you listening to RIGHT NOW?

Buckethead - Attic Garden (2016)

Half hour of whacked out instrumental experimental metal from the man with the KFC bucket. Much of it is frenetic and/or dissonant, but it also has occasional mellow ambient interludes. One of his better "Pikes" releases, IMO. I really like this!

I believe the highest official JEDEC standard speed is 3200.

So out of curiosity, what was your chosen solution -- a thread-safe replacement for ctime, or locks around the call? The runtime library already has a thread-safe version of ctime() -- ctime_r(). So that part was easy. In an extra bit of paranoia defensive coding, the code also now checks that the ...

The component cost aspect skews a bit more if you re-purpose old desktop hardware though. The only hardware actually purchased new for my last server build was the hard drives and the hot swap backplanes to put them in.

Re: How to clone Win 10 onto a larger drive into a partition the size of that drive?

It is very odd that the EFI partition is in the way. Normally the EFI partition comes first.

Have you tried using Clonezilla?

I'm voting PSU issue. Cheap PSU testers don't tell you how it will behave under real-world load, they just tell you whether it comes up with all voltages in spec under whatever (small) load the tester applies.

I love FreeNAS but almost everything you posted here isn't true. ECC, while recommended, is required no more than with any other filesystem. In the interest of (hopefully) putting this to bed, here's a post from Matt Ahrens (one of the original developers of ZFS) regarding the ECC issue: https://ar...

@demolition - ZFS doesn't require ECC. ECC is always desirable on any file server (regardless of file system) to help protect against bitrot and downtime; but ZFS isn't going to burn down, fall over, and sink into the swamp just because you put it on a non-ECC system. I suspect that part of this &qu...

This, of course, assumes that microcode patches survive a warm boot; the BIOS may overwrite with whatever microcode the BIOS has, negating the effect of the patch. My understanding is that the update mechanism (EDIT: the one on the intel chip) won't let you "update" to an older version. S...
