When you buy a table, you are paying for the wholesale cost for the wood, and primarily, the carpenters skilled labor. A carpenter can coexist with someone copying their table design as long as the market for new tables can support 2 carpenters.

A new drug is not at all the same thing. The marginal cost of creating a pill is basically nothing compared to the cost of developing it. A copy cat drug maker will put the ones who developed the drug out of business because the copy cat can sell it for pennies on the developer's dollar as they aren't trying to recoup development costs.

CommentRe:Colors (Score 1)80

"Real color" is sort of a meaningless distinction. Color isn't something physical or objective. A certain wavelength of light strikes the retina causing a pattern of electrical signal to be sent to the brain. Your visual cortex does some processing on it and another signal is sent to your pre-frontal cortex and you experience "color". This is called qualia, the subjective experience of a sensation. It doesn't really have a physical analog. It's a synthesis of signals in your conscious mind, something we don't understand super well at all.

CommentRe:1080p (Score 2)46

They want it to operate for more than a handful of hours playing a relatively modern game on battery power. Reducing the resolution in handheld makes sense to save power and you still get 4k when docked. An 8" screen @ 1080p is perfectly fine. Compare that to the Steam Deck OLED @ 800p or the ROG ally @ 1080p with similar sized screens.

A phone can manage 4k because it's not really doing anything graphically intensive when browsing the web or running an app. Any game that doing 3D graphics on your phone is probably running at 1080 or 720 and upscaling if it isn't sucking your battery dry.

CommentRe: A country that still uses Fahrenheit (Score 1)193

For me, I just find that Fahrenheit maps to a nice 0-100 scale for human comfort. 70 in terms of grades is a C, or average grade, and is an "average" comfortable room temperature. Anything below 0 or over 100 is going to require some special preparation to be outdoors comfortably for extended periods. Other types of weather fit nicely into 10 degree increments. 50-60 is sweatshirt weather, 90-100 is great for swimming, etc.

Yep, PGP is the only standard, currently, for trusted encrypted email.

That's not true. S/MIME has also been around forever and is widely used in government email systems and by the DoD. I'd wager if an enterprise is doing encrypted email it's probably via an internal X.509 authority and S/MIME via Exchange rather than PGP.

CommentRe: Chicken vs. Egg (Score 1)275

I he means the combined footprint of distributing 60 L2 chargers in a parking lot that accommodates 60 cars only adds up to 1 gas station, but the comparison is a little silly as they are totally different charging scenarios.

I do think they need to start installing DC fast chargers in a configuration that more closely resembles a gas station though. I.e. double sided and pull though. Right now they tend to be installed around the edges of parking lots, forcing people to back in, which uses more space, and makes queuing difficult if they are all in use. Both of these factors mess with throughput.

The purpose of a charger or gas pump is to refill a car with energy.
A single gas pump can fully recharge about 12 cars/hour.
A single level-2 charger can fully recharge one car in 8-10 hours.

Even where there are high-speed electric chargers the charging speed often drops when multiple cars are being charged concurrently. This is not the case with a gas station. Pointing out that these devices have different capabilities is not "moving the goalposts".

An L2 charger is not the same beast as a gas pump though. You can install an L2 charger in most single family homes, in apartment parking lots/garages, in shopping center parking lots, and office park parking lots.

With the exception of the shopping center, those are all places where it is impractical to install a gas pump for cost, logistical, and environmental impact reasons. Because of this it's totally practical and desirable to have a 2:1 or even 3:1 ratio of L2 chargers to EVs on the road. Just like we have way more outlets in our homes than are ever simultaneously in use, we should have an overabundance of L2 charging so that one never has to worry about where to plug in.

You need to compare gas pumps to DC fast charging for more of an apples to apples comparison. And if a sufficient number of L2s are installed, the lower throughput of DC chargers compared to gas shouldn't matter since most people will get their day-to-day needs met by L2 chargers and only need to the DC chargers for longer trips. Meaning that the gas station type of use case drops to a small minority of total car energy delivery.

CommentRe:Only Level 3 Matters (Score 1)275

You should only need L3 on road trips where you are actively waiting for your vehicle to charge. For day to day use public charging, L2 is fine as long as there are enough of them that you can park at one frequently enough to keep topped off. Beyond being wasteful and expensive to use for daily charging, they also shorten your battery life if used as your main charging solution.
