Alright, for those who want a big dump of practical knowledge on building and operating small-scale gasifiers here's the old GEK wiki: http://wiki.gekgasifier.com/w/page/6123718/FrontPage Be warned, ther

It works well if you use the turbo to feed air to the gasifier, creating a positive-pressure fuel system. Pulling from the gasifier runs the risk of fouling the turbo with tar and particulate, unless your operating conditions and filtratio

If everything is operating correctly then yes it's wonderful. If conditions are poor then you are in for a bad time. There are a lot of things that can cause poor gas quality, often having to do with things like biomass moisture cont

I feel you, but something like an R730 or 7810 with a pair of E5-2690 v4 and 128GB RAM can be had for under $400. Not the most power efficient, but you'd have to run it quite a while to make up the difference in energy cost. Plus the

I love it. I used to work for a company targeting markets in the developing world. It's really easy to take for granted the supply chains that exist all around us. I always like to see the creative solutions people come up with when

A couple years ago somebody parked a stolen car in front of our building, stuffed a rag in the fuel filler, and lit it. I must have pulled up just a couple minutes after they had left. Grabbed the fire extinguisher I kept under the seat a

I learned how to program the AVR in assembly 25 years ago by reading the datasheet and various articles in Nuts and Volts. For its time the AVR had a very accessible development kit, the STK500, which cost about $100. A few years later a

I'm sure somebody like me would happily take them off your hands. The AVR is still a solid platform for low-level applications. A lot of the Arduino libraries never really took full advantage of what you could do with that chip. Wha

That's a funny take, since reading the history of Luddism I've always interpreted it to be anti-capitalist. The Luddites were peasants that had their way of making a living disrupted by a high capital expenditure technology that

I'm more worried about all the sites that require my phone number under the auspices of two-factor authentication. It's probably the most trackable bit of personally-identifying information these days.

Yes, I think that's a good idea for high-value secrets. In a family situation it would be a great way to limit elder abuse (unless all your children hate you).

Yes, I agree much of the added complexity isn't necessary, but since TLS is a common and widely used protocol for just about everything other than SSH, it seems like it would be easier to plug in. Edit: or put another way, why should I

@alphazard, what are your thoughts on using self-signed X.509 certs, since 95% of the infrastructure is already there?

It makes sense to keep printed backups of certain keys and passwords in a physically secure location, accessible to the people you trust in case of an emergency.

I have an older workstation with no NVMe sockets. You can find 4 socket NVMe PCIe cards that let you bifurcate a 16x PCIe socket into four 4x NVMe sockets. Great way to make a local flash ZFS pool. https://www.ebay.com/sch

But how can those changes be made if the representatives don't act to make them? It would take a pretty big act of solidarity amongst various constituencies to send the message that failure to act is not an option.
