Pretty much all my sleep/suspend issues with Linux went away when I switched to Manjaro from Fedora on my 11th gen Framework 13. Sometimes it doesn’t work, but the majority of the time I can open my laptop after a couple days and still have most of my battery.

This is a topic that could be a novel for how much there is to consider, but in the end it comes down to resources and companies trying to choose what it best for the company overall. For a company to do anything, they are giving up many other things they could be doing instead. Whether it is limited budgets, limited personnel, or company priorities every decision made is always a tradeoff that means you aren’t doing something else.

Most companies prioritize releasing new product so they can start getting revenue from it as soon as possible. A new product has the largest potential market, and thus makes shareholders happy to see revenue coming in. The sales from a new product are the easiest ones in most product’s lifecycle. Additionally. releasing new products helps keep you ahead of competitors. So ongoing maintenance work is de-prioritized over working on new things.

The goal of testing is to simulate potential use cases of a product and ensure that it will work as expected when the customer has the product in their hands. It is impossible to fully test a product in a finite amount of time, so tests are created that expose flaws within a reasonable search space of the expected uses. If an issue is found then it needs to be evaluated about whether it is worth fixing and when. There are many factors that affect this, for example:

• How much would it cost to fix?
• How much time would it take to fix?
• Does it need to be fixed for launch or can it be a running change?
• How many customers are actually going to see the issue? Is it just a small annoyance for them or will it cause returns/RMAs?
• Is it within the expected use case of the product?
• Can we mitigate it in software/firmware instead of changing hardware?
• Is it a compliance/regulatory issue?
• Would this bring in new customers for the product?
• Was this done a specific way for a reason?

Unfortunately, after considering all this the result is often that it isn’t worth the effort to fix something, but it is considered.

Good to see you are out of your 5 year coma…

Paul’s online math notes are by far the best resources out there for the first few university level math courses.

It is a great shame that his linear algebra notes were removed years ago.

Part of it is just getting a feel for Chinese goods and using that to determine what is a good deal or what is a scam. I’ve worked with a lot of Chinese suppliers for a long time so I have a sixth sense for their bullshit.

Generally I avoid anything that could be a safety risk (e.g. Mains power) , and keep an eye on the photos to see if they look too good to be true. Official stores are good, as are items with many purchases and reviews that include pictures.

Was transiting through the Iceland airport once and had a random thought about how I was quite far from anyone I know there. No sooner do I finish the thought I look about 20m in front of me and an old university classmate of mine is walking towards me.

I can get just about any style of pizza I want from local shops, why would I go with a major chain? Rarely I’ll get Pizza Hut because it is its own thing that nobody else replicates.

Yes, someone stole a game console from my room in university. Then I caught them selling it on craigslist, contacted them, got their name and got them arrested and my console back.

Lucky for me that I had reported it to the police since I was considering using insurance to cover it. The officer that took the info recognised the persons name because he had pulled the guy over that week and thought it would be fun to catch him with stolen goods as well.

I wouldn’t worry too much about replacement batteries. They are just standard sealed lead acid batteries that you can replace with generics without paying the high OEM prices. The ones I’ve replaced are just a spacer between two batteries with a sticker holding it all together. I just took my bad ones to a local battery place, said I need replacements and then they recycled the old ones for me.

I do know that Cyberpower has some reports in the past of their UPSs being a fire hazard. Definitely caused me to go with APC when I bought one a couple years ago. https://www.tomshardware.com/news/cyberpower-upses-reportedly-pose-fire-hazard

I desperately want to know what you were imagining might happen when you asked this question.

It really isn’t faster though when you risk having some issue that requires help half the time.

No, purple is a non spectral colour meaning it is incorrect to call it “a wavelength” but rather you say it is a perception of multiple wavelengths. Not that this is special, pretty much everything you see is a non-spectral colour.

Or the engineers have been given bad requirements and made the wrong product.

“Please” is used more in verbal or formal communication in English. I wouldn’t typically use it when writing a comment here as online comment sections are considered informal written communication. But I would always say it if I was asking a food service worker for something.

My grandmother is like this. Then occasionally she tells some new story and we are all like, this is way more interesting why hasn’t this been part of your repertoire for the past decade?

I can’t even get Gboard to capitalize “i” FFS, you expect it to do something even more complicated!? The state of keyboards are so bad today. I remember when you could vaguely type or swipe in Swype or Swiftkey and it would get your word correct most of the time, now they all fucking suck, Swiftkey just happens to suck slightly less than GBoard.

Samsung M540 “Slyde” phone - The software was incredibly buggy including things like just randomly typing the wrong letter. Randomly bad tech is so much more irritating than tech you know is bad.

Google Nexus 7 (2012) - The tablet had defective chips that slowed down over time. Turned into a horrible slow piece of shit over time.

Not quite, conductor diameter is important to supply proper current, which will change depending on the impedance of your speaker. There are other values like inductance and capacitance in a wire that could affect how your speaker sounds. The good news is that you can pretty much buy any cheap 16 ga copper speaker wire and not worry about it, as it would take effort to make a speaker wire that sounds bad (and those companies are the type to try to charge you $1000/ft for it!)

Im not a coating scientist (I’m a design engineer) so I can’t really answer your questions in detail. But powder coats are typically polyurethane or polyester. There are different types of wet paints as well. Some surfaces also get an additional UV top coat for abrasion resistance.

For a phone button you might be looking at something like PVD coatings or platings. Chromating wouldn’t be used in those cases as it is not terribly durable but it provides a good surface for the coating that goes on top or it. All of thses coatings are on the scale of a few mils thickness.

Most of these finishes are done on industrial scales and even the manufacturers send them out to external places for finishing (e.g. in Asia that type of facility is strictly controlled for environmental reasons) . At the end of the day I just speak with my supplier and tell them the finish I want and they take care of the rest.
