Sustaining over 1GB/s on the TrueNAS server across two volumes. I could watch this all day…TrueNAS I/O


Finished watching season 1 of Only Murders in the Building. Thoroughly enjoyed the twists and turns along the way. Can’t wait ‘til season 2!

Spent 2 hours pulling the Miata engine apart to try and track down an oil leak with the help of an oil additive and some UV light. 90% sure it’s the front crankshaft seal.

Miata Engine

Gotta order some parts and will probably take me a day to finish the job. I’ll need to pull the timing belt and re-time the engine, so that will be most of the work. Really hoping I won’t have to drain the coolant, but we’ll see.


Watched the Who Killed the Electric Car documentary with the kids this evening. Still tugs at the heartstrings to see how electric car tech was delayed for decades by actions portrayed in the film.

But it’s encouraging to see just how much has improved in the years since.

Recently I’ve been giving TrueNAS another shot for shared VM storage.  This time around it’s working much better.  Here’s a video about my experiences in round 2.

Apparently if we put our minds to it, we really can flatten the curve… Too bad it’s retroactively. Graph showing current spike flattening previous spikes.


You know it’s a cold day when you drive on the highway for 15 minutes and your car still is nowhere near warmed up to its normal running oil temp.

My MacBook Pro 14” M1 Max arrived yesterday. My concerns about fan noise have been unfounded thus far.

I haven’t done any real heavy work yet. However, while installing a 2GB OS update and a few dozen apps (Xcode, FCP, Office…), the fans stay off most of the time. When they do spin up, they are at ~2300 rpm, and are inaudible from typical working distance in my quiet office.

If I hold my head close to the laptop, I can _just_ hear the air movement. At that point, my idle 16” MacBook Pro that is six feet away sounds louder. Heck, even my previous quiet Mac benchmark, a 2013 Mac Pro, is louder from 6’ than the 14” MBP from 6 inches.


Really impressed with the memory bandwidth of the M1 Max… 400GB/s is way faster than DDR4.

Single channel DDR4-3200 is only 25GB/s, so even EPYC servers with 8 channel memory only run at half the bandwidth.

A reminder to check your backups periodically. I was about to do a quick Time Machine restore this morning only to find my backups haven’t been running for the past 2 months.

I disabled them while traveling to avoid sending so much data over the VPN connection home.

Luckily, I had the files in another spot so I avoided data loss. Which brings up another topic…have multiple backups.
