There are about a dozen ways to get files to and from an older Mac like my PowerBook 3400c, but right now (at least until I figure out a good way to get my NAS -> an AppleTalk server -> 3400c working), my preferred method is via a CF card—I pop the CF card into a CF-to-PCMCIA adapter, then insert that into one of my PowerBook 3400's PC card slots, and bingo: removable flash storage on a 1990s laptop!

I still have a few CF cards kicking around (I used them with my old Nikon D700 camera), and you can buy a 4GB SanDisk Ultra CF card new from Amazon still—albeit for the price of $35... Sometimes the smaller/older cards work better with old Macs, and most of the files I deal with are well under a few MB anyways.

I've been building out a new Arm-based NAS using ASRock Rack's new 'Deep Micro ATX' motherboard for Ampere Altra and Altra Max CPUs.

I posted about the hardware earlier, in Building an efficient server-grade Arm NAS. Go check that out if you want details on the specific hardware in this setup.

But at the end of the build, I installed Rocky Linux, and found the power consumption to be a bit higher than expected—over 150W at idle!

As it turns out, the NAS must've been doing something when I took that initial measurement, because after monitoring it for a few more days, the normal idle power usage was around 123W instead.

tl;dr: 52Pi and Seeed Studio's water cooling solution for the Raspberry Pi 5 can be fun, and works better than any other solution—but at a steep price, and with a number of annoying quirks.

A few months ago, 52Pi reached out and asked if they could send a new water cooling kit they were working on for the Raspberry Pi 5. At the time, the hope was we could figure out a way to get very high overclock with adequate cooling.

Unfortunately—for reasons I'll explore more soon—the Pi 5 can't overclock beyond 3.0 GHz (it's not physically possible). Some of why is explained in my blog post Overclocking and Underclocking the Raspberry Pi 5.

But water cooling is still fun, and the product is in production now, so I figured I'd still give it a fair shot, and see if I thought it might be worth buying for certain niche use cases.

About six months ago, I finally reached a breaking point: my email-based TODO system stopped working.

It was beyond its breaking point for a few years, actually... ever since I my average daily email volume increase from maybe 5-10 'important' emails to deal with to 50+.

My email-based TODO system used to go like this:

1. Email myself things I deemed important enough to do the next day
2. Next morning, when I checked my email, knock off the top item in that list, and try to work down the list a bit
3. Anything else, forward that email again for the next day

Once an item got maybe 5-10 Fwd:s in the Subject line, I would decide whether to nix the TODO item entirely, or move it off into a Trello board—in either case, likely to be forgotten forever.

I didn't say the system was good.

But it did work, before my inbox became full of actually important stuff relating to running my business.

On April 8, there will be a Total Solar Eclipse covering an large swath of the US, offering hundreds of millions of people the opportunity to witness one of the most spectacular displays of our sun.

I wrote two blog posts about the recent 2017 eclipse, as well—check those out:

• Photographing the 2017 Total Solar Eclipse
• DIY threaded solar filter

For this year, I was considering going all-in on a custom Raspberry-Pi-based solar tracking system, recording video and images... but Will Whang already built a custom solar imaging setup that would put anything I build to shame.

It's not cheap, but it's efficient. At least, that's my hope.

Over the past few months, I worked with a number of vendors to assemble what I hope will make an efficient but high-performance arm64 NAS. In the video embedded below, I've put together the following (some of these links are affiliate links):
