Your ears have on the order of 1 megabit/sec bandwidth, so anything more is irrelevant, specifically Wi-Fi 6 is 1000 times overkill. Bluetooth uses about half the energy per bit transmitted compared to wifi. So, using wifi would cut al

Weirdly, you can only have three email addresses per domain. So you can't really use it for a typical family domain, even though it supports the family group (which can be six people).

In the US at least, high efficiency home gas furnaces bring in their own combustion air from the outside so they don’t bring drafts into the house. They also don’t have flues throughly the roof. The exhaust gas is cool enough that it goes

It is well worth any Tesla driver's time to spend two minutes reading the list of voice commands. Once you have a grip on the vocabulary and structure you can just tell the car to do what you want for dozens of common tasks. (Hint: It

Not my side of the pond, but clicking around on Gridserve I'm only seeing a maximum charge rate of 60kW. I haven't found a Circle K above 50kW. Ionity has chargers that go to 350kW. For comparison, Tesla superchargers are 150kW or

Depending on what your lenses are made of, and if you have fragile coatings on them, and if you live around or work with fine abrasives, this works fine. I miss actual glass, uncoated lenses.

As a Mac user from the beginning I was about to say "that's an iPad, not a Mac", but lo and behold! On a Mac now the alphabetic and digit keys do not autorepeat when held but instead pop up little menus of variants. Shifted a

They were salaried engineers paid to carry, not for the calls. The people carrying were capable of initiating remedial action and of knowing which engineer to call if it really needed midnight engineering. We outsourced the simple triage by

This is a frequent disconnect. It really depends on the scale of the business. In some large ones, there is always a person working to handle “must be fixed now” problems. If you are off shift, then it is the person on shift’s task. In smal

I’m sure other people use FSD as a bad chauffeur, but around town I use it when I’m willing to be extra alert and train it. There is a button I press when the car has messed up and the surrounding data gets sent back to the Tesla mothership

From my observations I can’t show causality, but the three situations where I used the feedback button the most all got addressed. - my city town inexplicably decided to make dashed white lines on the sides of bicycle lane sharing markers.

It’s an educational test, not a proof of knowledge. If you came away knowing not to vent, to use the right refrigerant, not to vent, to take your waste to the reclaimer, not to vent, to leak test with nitrogen, not to vent, and that you can

The “starve the beast” legislators underfund the EPA to the point that there is no money for enforcement, and enforcement at the technician level is going to be really unpopular with lots of “The government fined me out of business” stories

In the US at least, any refrigeration technician should already have passed his EPA 608 or 609 and be fully aware that venting a unit can cost him his card rendering him unable to buy refrigerants. Before working on all but small self conta

PCI-Express 6.0 and 7.0 both abandon binary signaling and move to four voltage levels per time quantum to encode two bits at once. That lets them move twice as much data in the same bandwidth, signal to noise ratio willing. Since they will

With UIKit you can query the device, it’s subpixel structure, and the alignment of your abstract window on the device and work it out from there. Mostly, it’s possible there is an abstracted display at a non-native resolution over something

Problems with pixel perfect layout were what made me give SwiftUI a 12 month “wait for maturity” last year. I hope this and the new SwiftUI custom layout capabilities signal an interest in this at Apple. I was making strip charts of data at

I think the most interesting part is that this is not a reverse osmosis unit. The feed water passes through an electric field which migrates the charged ions to the sides of the stream, which are discarded and the center of the stream is re
