For most people, using Linux is not a buggy experience. So no, people aren't gaslighting you. Normally, you grab a modern release like the latest Fedora or Ubuntu and you can get a live desktop up in seconds booting from a USB stick.

Esoteric hardware can be a problem if particular driver haven't been developed yet. That tends to hit laptops harder than desktops, but it's much less of an issue than it used to be.

People are asking for specifics because they don't share your experience and so can't fill in the blanks.

The fact that it's not protected is all down to America's fear of democratic socialism and workers rights.

When we pay the actual price and not the ad subsidised price.

Probably never. Those 2048 cores are all separate threads. GPUs work with a cluster of cores all following a single thread of execution.

MIMD Vs SIMD.

Not OP, but I doubt that's what he meant. An APU still has a CPU and a GPU on it as separate things.

Do UK citizens pay generation + transmission + taxes like we do in the USA?

We pay a standing charge per day. Mine is 40p. So every day my costs are 40p + my per kWh costs. There's also 5% tax on domestic electricity, but the prices I quoted include this.

No. Electric. My price changes every 30 minutes.

I wrote that message this morning when the price was low. Now at 5pm the price is nearer 40p. Obviously you don't charge a car at peak prices.

Over the last 4 weeks I've averaged 18p/kWh. That's mainly by making sure I do things like charge the car when it's cheap.

My rate is very variable, but the figure I used is the off-peak rate on a rate designed for EV owners that gives cheap overnight electricity.

My gas price is 5.9p/kWh which also changes, but day by day. Today is average.

All depends on the maturity of the process. 10% for a new design on a bleeding edge process is possibly viable. You'll then tweak the design and process to get the yield up.

  • 12.5miles per $electricity-dollar (17.1c / kw-hr home charging costs)
  • 17.1 miles per $gasoline-dollar ($3.10 per gallon last fillup).

UK figures:

  • Right now my electricity price is 6p/kWh, but the wind is rather high today (Storm Darragh). Still there are tariffs that guarantee 7.5p (9¢) overnight for car charging. That gives 24.3 miles per $electricity.
  • Petrol is ~£1.40 a litre here ($5.30 per US gallon). So, 9.8 miles per $gasoline.

....ish

The maths was right, except it was all being done on colour values than already had the CRTs response curve baked into them. You may have heard of "gamma correction". Well, this is when you correct an images colour values for the display you'll view it on.

Blending before gamma correction and after gamma correction produce very different results. The cards were doing it after. This story is about doing it before.

Paul Debevec had similar observations around the same time. His work at the time was all about HDRI and that was put into Source a few years later.

...but then you're losing quick copy and paste.

Select text then middle click on the window you want to paste it. No keys. Select and a single click.

Of course, if you have more than three mouse buttons you can do both.
