E! I love watching videos on it. Mark Rober’s player piano was pretty cool.

Movies nobody asked for.

I gave up on TP-Link. I will never purchase any consumer router from them again. Little to no updates, connection issues that were made worse with an update, features REMOVED with an update, settings wouldn’t always stick, which results in a factory reset to get it to do anything. WPA3 just doesn’t work. It even would “mysteriously” turn it’s DHCP server back on, no matter how many times I turned it off, when it was in AP mode. Friend had the same model and most of the same issues.

I have had better luck with the other brands, but I feel like most of them suck or cost way more than they should.

It was the SCADA view right? A lot of SCADA software is basically running on top of windows, though you typically would never see the desktop. Ignition at least is cross platform, but that is because the server is Java and Jython. A big part of why things are running on windows is due to OPC, which was traditionally all DOM and .NET. It is basically a standard communications protocol and is what allows your HMI/SCADA to communicate with PLCs. Otherwise, you use proprietary drivers and native PLC specific protocols.

SCADA programming/design is kind of an art and is usually written by an either an overworked engineer or someone who had far too much time on their hands. You basically build screens using specialized software, hook up buttons and UI elements to PLC signals, and pass some signals from the UI to the PLC. They are all heading in the Edge/iot/cloud/web based/techno-babble direction these days…

Some other random ones I have seen or used in the past: https://www.siemens.com/global/en/products/automation/simatic-hmi/wincc-unified.html https://www.aveva.com/en/products/intouch-hmi/ https://www.rockwellautomation.com/en-us/products/software/factorytalk/operationsuite/view.html

UL certification can mean different things, depending on the product and type of mark. It also isn’t that expensive to get UL listed as it isn’t like every single item you produce is tested. Each product you design is tested, but not each item you produce.

There are 3/4 types. UL listed, UL recognized, and UL classified. Certified is newer and more stringent.

• Recognized is mostly for machinery and components within machinery. It isn’t terribly difficult to get, but annoying. I have dealt with this type as we design and build electrical panels. Usually you hand the design to a panel builder and they will get it certified before delivery.
• Listed is for products and appliances, and is fully tested for safety. This applies to most consumer electronics.
• Certified Enhanced is also for products, and you can read up on it here: https://www.ul.com/news/qa-uls-enhanced-certification-mark
• Classified is for products and is half ass tested. All it means is that some requirements for UL were tested and passed, but not all.

If a product is Classified by UL, this can mean its testing meets the particular requirements for a single test with a published result, but has nothing to do with all the other tests that may form part of a Standard (i.e., UL 181).

As for pricing for UL listed, it can be just a few grand for a single product. Not much when you are selling thousands. I am sure Classified is even cheaper. I wonder how many of these cheap ass lamps say Classified.

No idea which phone you have, but dbrand does carry a decent amount of models. However, it is mostly limited to Apple, Google, Samsung, and One Plus. It does suck trying to find some things though. I do try to get things directly from the manufacturer website when it makes sense, but sometimes Amazon IS their website.

We had a student run server for piracy at my University to get copied textbooks from, but even then we had to sometimes look elsewhere. I often couldn’t afford books and not all professors allowed the cheaper used previous editions.

Science textbooks were the worst with their stupid fucking online code bullshit so we could do homework. They even made it where you could buy just the code, which was something like $70. Still better than 300+, but JFC. Having to spend over $1000 for books that you are only going to use for 10 weeks was nuts.

The last saving grace we had is all textbooks were required to have at least one copy in the library that could not be checked out/removed. You could photocopy the homework pages that way. If your classmates were nice, they would let you borrow theirs to copy any pages too. You could also buy your textbook, copy what you needed, and return it within the return window.

Same. I had to uninstall due to the battery drain issues. Pixel 6 Pro. Battery life is not something I am willing to compromise on.

Sames. They make sweet monitors.

Thank you! I didn’t really understand what drivers did in the whole scheme of things and it makes me appreciate what these engineers do. Now to go down another rabbit hole of videos.

I just got an Arc recently after not having any kind of PC build for over a decade. Still figuring out all of the things I want to do with it, but I haven’t had any complaints with performance on the couple things I tried. Looking forward to spending more time with the hardware and watching more videos!
