This is hackish, but I find this extremely useful for troubleshooting. I have this in root's crontab as a time marker.

`0 */4 * * * /usr/bin/date > /dev/kmsg`

This way, it doesn't just have timestamps in the logs, but also `dmesg`, where an absolute time is easier than seconds from when it booted up.

By moving to mini PCs, and NAS chassis, I notice that I save around $100 a month month on power. Previously, I had several full towers. The biggest change was moving to a Mac Mini a few years back from a full tower PC.

Mini PCs are essentially laptop motherboards anyway, and you definitely lose performance, but for what I do, it was worth the trade-off.

I still wish Red Hat / IBM would not just have btrfs as a filesystem, but support it. They do this with fedora. ZFS would be nice, but because it taints the kernel, I can see why this isn't done.

Replying to

@RantingCanuck I am weird... I don't believe that cutting taxes is a good thing. It is like someone who has a table knife saying he is going to operate, or someone with a drill and a reciprocating saw saying they are going to remove weight by carving out random sections. Recessions are when governments need more resources, not fewer.

Now, the weird question. If one can get a hardware RAID controller with battery backed up RAM for cache, the cache only works if the controller is doing RAID. In JBOD mode, the controller is not used.

I saw one article in Sun's (pre-Oracle) documentation that ZFS is supported on hardware RAID. However, you lose bit rot correction. This is mitigated, if the RAID controller patrol reads though.
