Edit: thank you to people upvoting this comment, but I do regret it. The only good I now see in it is that it spurned further discussion and clarity. If you upvote this post, do read and upvote the parent comment and reply comment from anon6789, there are good insights there, at the very least.

Then any carbon removed from the atmosphere gets released when the pellet fuel is burned. Add in the carbon from making the pellets and all the shipping and cutting down the trees and replanting, and we're worse off than when we started. The net pollution they say is greater than coal or natural gas.

This makes no sense.

The net pollution they say is greater than coal or natural gas.

If "they" are oil and gas corporations, I'd say that too, if I were them. Any move against our bottom line, or competition to our subsidies is fair game for attack.

How is that wood's problem exactly? How did that carbon get into the atmosphere in the first place to be turned into wood? If there had been no coal, gas, or oil, that atmospheric carbon would have been from burning wood in the first place, making it a net cycle of wood. It grows in short order regardless of what we do with it; it's renewable.

There's a competitor to fossil fuels, returning carbon to the atmosphere, it's been burned literally forever, and oooh suddenly it's the one to be concerned about, not the other carbon emitters that can only emit, never absorb? Come on.

carbon from [harvest, manufacturing, packaging, shipping] ... we're worse off than when we started

As if the extraction, manufacturing, packaging, and shipping for fossil fuels doesn't emit vast amounts of carbon? If wood was harvested, manufactured, packaged and shipped with renewable energy, what's the problem? Why couldn't it be? If fossil fuels were harvested, manufactured, packaged and shipped with renewable energy, I'd say "cut out the middle man" and just use the renewables directly for energy. Is that your beef?

In that case, let's harvest that wood anyway, turn it into charcoal, and sink it to the bottom of the ocean to get carbon back out of our atmosphere permanently. If you think that's a ridiculous undertaking, it's even crazier to think about the absurd amounts of carbon we are digging up and plain dumping into the atmosphere every day, and that wasn't complained about first, before complaining about wood of all things. We don't just need to stop emitting new carbon, we need to get it back out of the atmosphere forever, and that's not even on the radar? Hmm.

What do you suggest we do? All I'm seeing is rhetoric is that trees are a grift, while suspiciously overlooking the fossil fuel subsidy grift.

I have not read your whole comment yet, but I apologize for my heated reaction. Your post came off as oil and gas promotion to me, but that's clearly not the case. Thank you for your thoughtful response. I will read it more fully later.

Evolution doesn't demand anything, it's literally about adaptation. The expectation of infinite growth inside an obviously finite system is the death cult.

making a carbon copy

Is making it difficult?

Dude, you are the greatest of all time. Thank you for posting this.

Edit: do/have you ever used sausage anywhere in there?

Is this announcement that caused Elon to have his hissy fit and axe the supercharger team? What a short sighted dumbass. Demand for good quick charging would go through the roof with this, and Tesla already has the leading charging network with arguably the best implementation in terms of ease of use. You have to wonder if he has prions in that noggin of his.

TIL the dev of Iron Lung, an acclaimed indie horror game, faced significant backlash over increasing the price from $6 to $8 ( www.ign.com )

Then, responding to those who have said he’s “only doing this for the money", Szymanski tweeted: “Yes, no fucking shit. I make games for a living. If I didn't want to earn money from them I wouldn't charge money for them.”...

I forgot that everyone is forced to buy this game. This price increase is an outage. If only the people who thought about playing it could make the decision to buy it or not, then that might be reasonable. But come on people, this game costs more than a small pizza half a small pizza!

I was in the industry for a decent amount of years. I know the operators of the water plants around me. I never hesitate to drink the tap water in my area. At home it goes through the filter in my fridge, which manages the runoff taste in the spring, and keeps the water cold.

Ignition from Inductive Automation. Works great on Linux, used to run it in docker even. There are drivers for all kinds of PLCs. It's a dream to develop in, was my SCADA platform of choice (I've moved on from the industry). If you need to script anything, it is in Python, not some bullshit proprietary scripting language, nor VBA garbage. The client software is great, even runs nice on PC-based HMI touch panels, which you could install Linux on if you want. The call-out alarming actually works (FUCK WIN911).

The software is free to try and download. You can develop in it for free, unlike the majority of competitors. Go ahead and try all of it out right now if you want. The training courses on using their software are free, nice handy videos, so you can start learning how to build everything like right now.

The "catch" is it costs money to run all of the SCADA critical components for more than an hour at a time (to prevent you from just using it to run your whole plant for free). But you can build your whole SCADA app today with your PLC gear on hand, and only pay for it once you are ready to deploy to production.

Anyway, to me, it's hands-down the best SCADA platform, and it even runs on Linux. Disclaimer: some of this might be out of date, I've been gone about 4 years.

Edit: sorry, didn't see the "free" requirement. I would never run a critical plant without support, so I've not explored any fully open source options. If your plant is serving more than just your farm/homestead (in other words, is serving the general public) I strongly recommend a supported option for your client. If you get hit by a bus, and the plant is in trouble, they'll have a hard time finding someone to get them back online who knows your "weird" software.

That said, depending on your needs, Ignition can be cheap AF (comparatively) if your plant is small.

Please don't take the following as me being a dick, I am just genuinely curious. Your response is unique and interesting to me.

I have no idea what you are asking

Then why did you feel compelled to respond?

The rest of the thread is filled with people who know the topic and gave relevant responses very specific to OP's situation. Many hours before your response in fact. I'm a little perplexed.

Maybe custom built software

Any person (with enough budget) could get software built, but that's obvious to anyone, so it's kind of redundant to suggest, so why write it given the other responses? I am further perplexed.

Just install Gentoo. It will fix your problems.

I take this as humor. OP was looking for software to run on Linux, not a Linux distro. Was that the joke?

Anyway, I'm sorry if I have come across as critical or insulting. I really am just curious. If I have, and it's any consolation, if you care to genuinely answer my questions, I'll give you a short explanation of what OP was on about, if that is helpful to you. I think it was very kind of you to respond to OP, I think I'm just confused more than anything.

August27th ,

Thanks for your response. Sorry I didn't get the joke.

As promised, here's a "simple" explanation of SCADA, or as simple as I can make it at least. It will probably be rudimentary enough to be controversial, and long enough to be boring. Oh well.

It stands for supervisory control and data acquisition, and if you think that's a weird mouthful, it's because it's old and comes from a time when clicking graphics on a screen was a novel idea, and logging swaths of data with a computer and searching within it and rendering graphs from it was cutting edge. The term is basically relegated to plant, industrial and manufacturing type processes where a bunch of engineering has gone into it. Processes like brewing, water treatment, factories, assembly lines, etc.

Those processes are automated with special computers called PLCs that are basically "robot brains" that control things like (but not limited to) motors, valves, pumps, conveyers, robot arms, all kinds of stuff to manipulate the physical world, and can receive information from sensors like (but not limited to) pressure, speed, flow, weight, on/off, open/closed, temperature, distance, or anything else that someone has built a physical world sensor for. You can put all that stuff together with a program in the PLC and automate practically anything from beer making to zebra counting.

And that's all well and good, but if you want to see what the process is doing (supervise it), or stop it if it's gone off the rails (control), or see what it did last time (data acquisition), you need SCADA. There's special software to build a SCADA system with, and it's mostly special because it needs to talk to the myriads of PLC (and related) gear out there, and until relatively recently, it's been tied to an ancient Windows technology called OLE, meaning if you wanted SCADA in your industrial process, you had to suffer with the rather unindustrial wart of Windows in the middle of it. OP is seeking the industrial Holy Grail of a windowsless process in their plant.

We take it for granted today that we can build an interface in a web browser, and hook it up to control a USB device, all in one day, but 40+ years ago there was Windows 3, serial devices, and no commonly established way to communicate with gear (which OLE kinda solved), or standard design of how interfaces should look or work. Ignition brings all of that old shit into the modern world.

A relatable example you could call "baby SCADA" would be a smart thermostat, if it has an onboard temperature trend graph. The process it controls is your automated home heating and cooling. The smart thermostat can tell you if the AC is running, you can change the target setting that you want the room temperature to go to. And if it has a graph of the temperature for the last 24 hours so you can see that the schedule you set worked, then it's basically a 'lil SCADA.

Cheers.

Bro! Download Ignition, it's free, do all of the free courses, get the certification (also free I think), put it on your resume/CV and get yourself a job in automation! It's in demand.

IMO It's cool as hell to control machines as big as a room with a click of a button on an interface you built with your own two hands, lemme tell ya.
