Interesting. Do you have any sources on this or more reading material behind it? I have yet to really see any things suggesting utilities are asking to do CapEx on infrastructure improvements but are being told no.

Small tractors are easy. The issue is efficiency. The big tractor is big because the tool it pulls behind it covers ~10 rows per pass. You can easily build a small tractor that does 1-2 rows per pass, but that means you need a lot more passes, which means doing anything takes a lot longer.
I assume by "Raspberry Z-Wave module" you mean the RaZberry z-wave addon board, and I couldn't agree more. I tried to get that thing going with another home automation package and gave up after a few hours of fucking with it.
That said, these days I'm using Home Assistant on a RPi with a Nortek z-wave/zigbee combo radio USB interface and I couldn't be happier. If you've never used HA it's worth trying out; used to require a lot of scripting but now it's a beautiful and polished system that has all the tweakability a nerd wants with a nice high-WAF GUI. They have a plugin that does exactly what you're doing and makes a virtual alarm system out of existing sensors.
I also agree block connections and use a VPN to access it, I do the same thing.
Actually it's pretty well understood.
The human body reacts to CO2 buildup with a 'gasping for air' sensation. Nitrogen however, not at all. The air we breathe is 80% nitrogen 20% oxygen, so we aren't sensitive to nitrogen at all. Breathing air with little oxygen is something well understood as it can happen to pilots of unpressurized aircraft. Here's a funny example of what happens when pressurization fails. Once ATC figures out he has hypoxia, they order him to descend to 11,000' (which is usually the point hypoxia starts to kick in) and he's fine. But while he's hypoxic, he happily admits he has no control over his airplane and is totally unbothered by that fact.
There's a thing called a hypoxia chamber- the oxygen % of the air is reduced (not eliminated) to simulate what it's like being at high altitude without pressurization. Always funny videos there, grown men with oxygen-starved brains playing with a children's puzzle trying to put the square block in the round hole.
Execution by 100% nitrogen is the most humane death I can think of. The gas is odorless, and as it takes effect the prisoner would experience a euphoric feeling before just falling asleep and dying a few minutes later.
That said, I'm sure they'll fuck this up somehow- most civilized people have concluded that execution is barbaric and unnecessary, so whoever builds the nitrogen gadget is probably not going to be the sharpest tool in the shed.
And that's what a botched execution would look like- if you shut off the nitrogen too soon or don't ensure a high enough nitrogen concentration, the prisoner will be left with brain damage but not dead.
Very interesting. So you basically have an alarm system in software then? What do you use for software? Do you have an arm/disarm function?
Of course it is.
We have more energy consuming stuff than ever. But do you ever see NEW substations being built? NEW long range power lines? I don't.
Around here, the utility has a deal- they will sell you a top of the line $400 color touchscreen WiFi thermostat that talks to Alexa and displays the weather report and does a bunch of other shit, for $10 (not a typo). In exchange, you let them remotely shut off your AC if the grid gets overloaded.
Why do they do this? Because a few truckloads of thermostats (with a bulk discount) are a fuckton cheaper than actually upgrading the grid.
And so we hear about grid overload days and possible brownouts and incentives to shut stuff off as if this is the way it's supposed to be. But the reality is these problems only exist because utilities don't keep ahead of necessary upgrades. After all, why spend the money when there's shareholders to answer to?
security? For surveillance or something more?
This is harder than it looks.
See those rows of crops? On most farms, you need to be able to drive a tractor through them. I don't mean a riding mower, I mean a giant thing that pulls a tool that's working on 5-10 rows at a time doing things like tilling, seeding, fertilizing, harvesting, etc. If there's big metal pillars every row or every other row, that tool can't be used.
Thus, as pictured, those kinds of panels can only be used on a farm that's not using large multi-row agriculture machinery. That means it'll work for small family farms but not the large ag operations where this sort of tech could really kick ass.
What I would really love to see is more solar over commercial parking lots. That means a million little projects instead of a few huge ones, but think about how much surface area that is overall. It's huge.
The key to doing that is twofold- 1. create a few cookie-cutter designs for the frameworks that can be tweaked for individual projects, and 2. remove red tape from their implementation.
It should be possible for a business to buy off the shelf plans for such a thing, have a local engineer tweak them for the project specifics, and then have a local contractor do the installation, and have this happen in under 6 months.
As it stands, building anything above where humans will be involves a nightmare of engineering and insurance and liability, making it cost-prohibitive for most companies. That needs to get easier. I believe every parking lot should have solar above it- that not only will produce a ton of power, but it'll keep the cars cooler in summer.
The key is make them easily removable.
If it's 'removable' but it requires heating the edges of the phone up to 120F and then prying apart a sheet of hair-thin glass without breaking it, then most people won't bother.
If it's 4 Philips head screws then you'll find a lot more people doing it.
Unfortunately, the economics for device manufacturers are clearly in the adhesive category- cheaper to assemble, and they'd rather a user buy a new device than service the old one so they DGAF how hard it is to service.
The only exception is companies like Fairphone catering to a niche audience of nerds who value repairability. Most people don't even consider how hard something is to fix when buying it.
Sadly I think legislation is the only way to fix this. You have to legislate either a. that the battery be removable and replaceable without tools or 'with standard fasteners and not adhesive' or something like that.
The only way to really fix this is to stop gluing phones together.
I'm a liberal gun owner.
Neither gun owners nor conservatives have bloodlust. What we do have is disdain for laws that don't actually help the problem but just punish gun owners.
Take this 10 round magazine law. You know what is the difference between a 10-round mag and a larger one? A little rivet pin that stops you from putting in an 11th cartridge. Anyone with a cordless drill can remove the rivet and turn their 10-round mag into a bigger one. Anyone with a 3d printer can make a larger magazine. A magazine is just a box with a spring and some plastic bits. Making it longer is not rocket science.
The threat of 'drilling this rivet is a felony' does not stop someone who wants to commit mass murder. This law does not stop murderers or save lives. It just makes life harder for gun owners, as the pinned magazine is much harder to clean.
I'll also remind you that the guy who shot up VA tech had a .22 pistol (pretty much the least powerful gun you can buy) and a backpack full of 10-round magazines. He complied with the law and it didn't slow him down.
So stop accusing people of having bloodlust, and ask why they don't support the law that seems obvious to you. You might learn something.
Or just get a ZigBee hub and keep using the bulbs without the Hue hub
It's not. In the view of many, civilian gun ownership is A Problem To Be Solved. Such people do not draw a distinction between law-abiding gun owners who keep their guns secure and threaten nobody, and violent criminals and psychopaths who frequently kill people. Thus, with that view, any law that restricts gun ownership or reduces the number of guns in society is progress.
In reality, this law will do absolutely nothing for public safety. It will make the lives of gun owners harder, while the criminals and psychos will ignore this law just as they do every other law.
