Except that all "certified" cables are certified not by the manufacturer but by the USB IF. They're just USB Power Delivery cables and they're interoperable across all manufacturers that implement this spec.

The only major standout I've seen in Android land has been OnePlus phones and bricks. Maybe more Chinese manufacturers have their own spec too.

You didn't mention how CO2 raises energy accumulation (heat) by lowering how much radiation is reflected back out as it has specific absorption bands that are outside of other greenhouse gases that don't absorb the same, causes ocean acidification, has a lifespan that's 2-3x longer than other greenhouse gases, and it's been emitted in record numbers only recently, creating anthropogenic climate change.

"Earth is getting warmer when it should be getting cooler that's how I know climate change is wrong" is a take. Not a good one. But it is one.

But hey since you seem like quoting NASA

https://climate.nasa.gov/ask-nasa-climate/2949/why-milankovitch-orbital-cycles-cant-explain-earths-current-warming/

"Finally, Earth is currently in an interglacial period (a period of milder climate between Ice Ages). If there were no human influences on climate, scientists say Earth’s current orbital positions within the Milankovitch cycles predict our planet should be cooling, not warming, continuing a long-term cooling trend that began 6,000 years ago."

Which is 100% meaningless. Here is the real science:

We live in what is called an 'inter-glacial period.' They're short, about 10K-to-12K years. But as our orbital dynamics change, the earth gets cold again. Global temperatures over the next 10K years will drop between 12C and 15C. We have understood those cycles longer than you have been alive. But the fear-mongers don't care about that. After all, 'don't worry, be happy' doesn't get you political power through fear-mongering with pseudoscience.

Or as NASA says:

>Cycles also play key roles in Earth’s short-term weather and long-term climate. A century ago, Serbian scientist Milutin Milankovitch hypothesized the long-term, collective effects of changes in Earth’s position relative to the Sun are a strong driver of Earth’s long-term climate, and are responsible for triggering the beginning and end of glaciation periods (Ice Ages).

Strong is the wrong word. Primary is the correct word.

In fact, you can see the cycles when you look at EPICA (European Project on Ice Core Analysis) data (which is brought to you by Wikipedia) and you can see with your own eyes that 120K years ago it was warmer than it is now. And a 120K years before that.

There was no industrialization to cause those temperature spikes leading to inter-glacial periods. Humans barely existed.

Yet when you look at the obvious pattersn, you can see the inevitable the global temperature changes caused by the Milankovitch cycles. That's actual science. Not 'lets scare the shit out of people for political power' psuedo science.

Milankovitch driven-climate cycles have been verified by EPCIA, by astronomers and by geologists who (studying sea-core samples) who also discovered the same cycles. But Al Gore can't sell a you line a bullshit if you know how it really works.

A lot of that pricing started out as a result of binning.

Making CPUs is really hard, especially with larger die sizes, so you're likely to end up with defects in some of the chips you make. But since the defect might only affect some of the cores on the chip, you can just disable those cores and sell it is a 4 core chip instead of an 8 core.

Eventually the manufacturing process gets better and better and you have fewer and fewer chips with actual defects. But you don't want to cannibalize sales of your higher end chips, so you just artificially disable cores on some chips to keep your market segmentation intact.

They would also do similar things with CPU clocks as what you mentioned for RAM- where they would test each CPU and the more stable ones were sold as higher speed chips, and the less stable ones as lower speed.

I'm in a business that's stuck in the middle between the likes of JD and the people using the machinery.

Every year there's a new scheme to lock purchaser's into only dealing with the manufacturer for their new machinery. From service agreements that are sold alongside the machine to proprietary tech to lock them out to needing manuals only available to dealers to translate error codes the machine throws out to something which you can understand and then try and (possibly) fix.

It's not great
