  • When a former employer sent me on business trips, the bean counters would complain that my descriptions for the purpose of meals on my expenses were not descriptive enough, as if the purpose of eating was not obvious. I ended up writing something like “nourishment to remain alive while traveling for XYZ project” out of frustration after that. That did the trick and shut them up. I suppose it was hard to argue that description, because if they disputed it, they’d basically be admitting they were sending me away because they wanted me to die.






  • So you’ve got me thinking about a potential dark browser pattern relating to this that I think was introduced by Google in Chrome.

    Wayyyy back in the day, you might have a page full of animated gifs all doing their thing, and what you could do once the page was loaded was to hit the stop button (or hit the stop button twice if the page was still loading), and all of the gifs would stop animating. Today you couldn’t do that, because the stop button has been intertwined with the refresh button; once the page loads, the stop button turns into the refresh button.

    I bring this up, because there used to be a simple universal mechanism to indicate that you wanted to stop things from moving/animating, and it would do so, but now there isn’t. Funny how that mechanism has been subtly removed from an advertiser’s browser, where it is in their best interest to keep the ads blinking and changing to draw your attention to them.

    It’s too bad that there is no longer a mechanism that is as simple and universal that can stop movement. Now every site has to devise its own way to handle stopping movement, and there will be competing standards and methods, and it will no doubt end up being a pain intentionally, just like cookie popups.

    Maybe browsers should bring back universal stop for animated gifs, SVG, video, and (some) CSS, with an event to notify the page script.


  • I can’t help you with your animal fear, but I’ll give you a higher priority reason to avoid a cat for now.

    I’ll give what will probably be an unpopular opinion; cats (and pets in general for that matter) are a luxury… item. I have 3 of them, and I would never recommend one to a person who is struggling financially and/or has lost their job. Their food and vet bills are not cheap, and even a cat that seems perfectly fine can suddenly have an issue that requires an expensive vet visit. As they age, they will inevitably have health issues, which not only adds more expense, but increases the rate at which expenses accumulate. They can also damage things and ruin things, which adds further expense.

    All of this is fine, if you can afford it. However I don’t think very many people actually sit down and work out the numbers. On top of food, litter, and equipment costs, IMO people should be saving ~$70/a month for the first 5 years, then maybe half that after that if you didn’t have to use any of it, to be prepared for big vet events. It sucks not being able to afford the care your pet needs.

    Further, I have found that having multiple cats does not decrease the amount of expense per cat due to expected efficiencies from overlap. There are subtle things that accumulate like cleaning expenses and drain on your time and greater resources. I wish I only had one cat, honestly.

    People say you can’t put a price on them because of their cuteness and company and what have you. But believe me, you can if your cat(s) turn out to be absolute dicks, but nobody talks about that either, IMO because of some kind of Stockholm syndrome, sunk cost combo. People generally gloss over the shitty parts of pet ownership.

    Don’t do it. Be well-off first. Your GF’s sister is probably finding this out.










  • 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.


  • 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.


  • 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.
