You set up the base station over a known point, and now your rover unit can give you cm level accuracy when it's within range of the base station (UHF radio range generally).
For a practical application, let's say you wanted to lay out crops for a small hobby farm. This can make getting your base station set up, because you might not care as much about absolute location, which would require finding a surveyed benchmark. Instead you put your base exactly on the corner of your plot, and after setting up a local grid system you can now exactly layout your farm according to your plan. You simply walk around with the rover unit and can get real time cm accurate "coordinates."
This article spends more time discussing observable differences with the next generation and less on deeming them doomed.
The majority of articles out there fit your statement, but I think this one is worth the read.
I would probably buy custom tailored everything if price weren't a factor. I have annoying proportions so most mass produced clothes seem to fit me poorly.
I don't think it would be that much of a hassle, simply have all your measurements taken and keep that on file somewhere. Whenever you go to buy new clothes submit that info and get your nicely fitted t-shirts.
Not sure how this is any better than a good composting toilet set up. Grew up with one in the house (hippy parents) and it doesn't smell and is minimal maintenance. Not sure how well this would translate into an urban setting but that seems like a solvable problem (and a better approach than a subscription based service like this one).
Looking at that Wikipedia page, the composting toilet sounds rather more complicated and expensive. Also potentially it does not destroy pathogens completely. The approach of the "Loowatt" keeps the residential installations simple, sanitary, and inexpensive, and locally centralizes the composting in a process that uses high heat to completely eliminate pathogens.
This. Sometimes decentralized solutions are great, but most people don't want to become experts at the sanitary biological processing of human waste (especially inside their own home). For safety and efficiency reasons it makes sense to aggregate that at the community scale. Think of it like the local sewage treatment plant.
Actually it's better than a conventional sewage treatment plant, because
* it safely recycles fertility (interrupting the fecal-oral route, unlike "night soil"), providing a sustainable alternative to phosphorus mining and other fossil fertilizers
* it doesn't discharge fertilizer into waterways where it causes eutrophication and "dead zones"
* it produces biogas energy rather than being a large energy consumer
* it doesn't squander potable water to transport human waste, and
* it doesn't require a huge network of underground pipes, which have enormous embodied energy and replacement cost. If your city can't afford to replace the underground pipes, your water system is insecure and unsustainable for that reason alone.
Yeah those are good points. Also I realized that we have a "subscription service" with indoor plumbing through paying for water. There's no reason something like this couldn't be paid for through a tax which would encourage wide scale adoption.
Would a 512mb RAM DO server be enough for this? I've been looking for an alternative to a VPN for a while, but it would only be cost effective with the $5 option.
Yes. Your bottleneck will most likely be network and CPU speed as that's used for encryption. Google around for specific numbers, but my intuition is that network will max out before CPU does even on the $5/mo instance.
Could it be some fallout of the story[0] posted on reddit 11 days ago in regards to the shilling? I know that personally that has increased my time spent on HN.
