I was lucky enough to take David Beazley's "Rafting Trip," a five-day training course that guides each student through building their own Raft implementation from scratch:

I'd recommend the course to anyone with development experience working with or near distributed systems. David is a fantastic instructor and facilitator, and the blend of student backgrounds led to some great learning and discussion.

(I have no financial or personal interest here; I just loved the course.)

You can do this below ground level, but it loses some other useful properties (catching more sunlight, improved drainage, ergonomics). Depending on where you live, one approach may work better than the other.

The permaculture community emphasizes the concept of “appropriate technology,” which depends on context but generally means “seek simple/low-impact approaches.”

If you’re building large low-input beds that could last for a decade or more, a tractor might be an appropriate tool given your local constraints vs. a crew of horses/humans and a great deal of time/energy.

It’s possible to raise chickens as part of a broader regenerative system where much of the feed is an output from elsewhere in that system. This has been done profitably by folks like Joel Salatin, but it has its own constraints (for example, availability of pasture land).

A surge from a lightning strike near my home travelled over the cable line to kill a network switch and the WAN port on a firewall. (Strangely, the cable modem was spared.)

Everything was on a decent UPS... but I’d completely forgotten the cable line.

My layperson's understanding of the furnaces producing silicon ingots is that they can't power down in-process; best case, they take weeks to bring back into service, while the worst case is serious damage to the equipment as the silicon inside recrystallizes.

I wonder if it's even possible to ramp down this single process without a similar hit to productivity as an uncontrolled power loss, never mind the other stages in the fab process. If not, fabs can consume tens of megawatts, so what does it cost to build and maintain the necessary backup generation capacity to weather a 30-minute outage?

One interesting example: USD $1.5 million for 10MW of flywheel-based backup capacity (http://ir.p10industries.com/news-releases/news-release-detai...) - but these will last ~15 seconds under full load.

Due to physical limitations of the medium, mastering the vinyl release of an album is often (usually?) a separate process than mastering the digital version.

One of the consequences is less compression/clipping, better dynamic range, etc. for the vinyl version. This can have a huge positive impact on sound quality.

You don't have to be a nutbar audiophile to appreciate it, either - you can even hear the difference between old rock albums and their heavily compressed re-releases.
