What caught my attention the most was the usage of 1-bit images. Clever restrain of resource usage, and interesting in its own right.

> If there's one thing you can do to save energy, it's probably to dry your clothes on a rack outside Here in NM, you can take a load of athletic gear laundry outside to hang up and by the time you're done hanging it, the first items are already dry :) In winter, it takes about twice as long, indoors. So .. yeah.
Dry it inside in summer for the free cooling.
OTOH in Winter you may want the extra humidity.

The "port blocking" may just be a symptom of how the modem connects to the internet, rather than being a malicious act by the ISP. CGNAT is becoming a common way for ISPs to connect consumers to the internet, even here in NZ many ISPs use this. It basically puts a bunch of consumers behind the same NAT interface meaning that port-forwarding no longer works.
He's an Australian, and so am I. His ISP (Optus) doesn't go out their way to block ports. However, he says he's using a AC800s 4G/LTE modem and backs that up by saying is using mobile data. The default mobile data service from all telco's will use CGNAT and will hand him some 10.0.0.0 address. I presume that's because mobile phones don't run servers as a rule, so no one notices and it saves them a bit of money. They…

> Wait, but it already physically moves to track the satellite It doesn't. It moves to be in the same plane as the satellite, but it doesn't actually track the satellite. The phased array can only track a single line across the sky. The dish moves so that line is parallel with the satellites orbit.
Ah, so if I understand it correctly they (motor and phase array) basically each do one axis?
But after an initial aiming, the motors basically lock in place and the dish stays still. The phased array then tracks individual sats in orbit.
> …bit of reverse proxying with Nginx is needed also… Nginx reverse proxy has capability of caching static assets, does it mean most of the website is actually being served by cloud? So, technically raspberry pie should be consuming power only when cache timesout.
Article author here, your question is actually a really good one as I'm a bit of an Nginx newb and your comment had me wondering that too. However for the past few hours since this article has been shared the hits have gone quite crazy according to the Raspberry Pis access.log, and the Pagekite.py process is constantly around 30-70% CPU usage, implying a heavy load as normally it uses nearly nothing. Does Nginx rever…
Second blog post is about how great Gab is? yikes.
Very cool, though I'd imagine you'd have a pretty good chance of success at just sending the power over that 110m ethernet span.
Not directly related to solar-powered-servers, but rather power-involved-in-computing ... I have a solar powered van (not the engine, alas), and it has been amazing to understand how a day of my kind of computing (edit/compile/debug cycle with C++) uses more power than the 12VDC refridgerator in the van. The computer is a small custom built direct-to-12VDC miniITX with an i5 processor. The refridgerator literally has…
I've got a PowerWall and the Tesla app (which shows up-to-the-second readouts of your home's production & consumption), and it was shocking how little energy refrigerators and freezers use. Apparently it's because they're extremely well insulated; the compressor only needs to go on to adjust to changes in temperature, and if you don't open the door the temperature won't change much. There were a bunch of other surpri…
They use only about half the energy.
If you want one, head to any shop that sells appliances, and search "heat pump". Mine paid for itself within a year. You can also buy one 2nd hand for faster payback.
