The Intel processors all ship with Minix in their Management Engine. The Apple iOS devices all have L4 in their security enclaves. Both of these OSes have open source options, though the ones shipped in the processors are closed.

About 1km as the fiber goes. It’s easy to see why we are an early install. High income area, relatively dense free standing houses, all aerial poles. It doesn’t really get any easier than that so the telco can say “we have gigabit fiber in

I just had fiber pulled into my home. It was no more difficult than the copper line which preceded it (which we used as a messenger to pull the copper through my buried conduit.) An aerial install would have been identical to copper. Just f

When I saw the official adapter was 5.1 volts I just mentally relabeled that port as “proprietary power port” and got their adapter. They fudged their power supply voltages up on previous models to handle drop in the regulators. I presume t

Both Xiaomi and Oppo shared videos of the in-display cameras working, but the videos are too low quality to make any kind of image quality determinations. That coupled with a lack of even controlled lighting, best case sample images proba

Not a European, but I regularly live in 39°C, 102°F with very high humidity. Get a portable, floor standing unit in the 1500 watt range so you plug it in anywhere. It will have a fist sized duct to exhaust hot air, stick that out a window.

About having to leave light switches in the on position… Your pain has been felt. Searching the web for "smart light switch cover" will find secondary switch plates which snap on top of your existing switch. They prevent anyone fr

It’s more like becoming a partner or working for shares. Rather than getting a fixed price up front you take a (presumably larger) payment at a later date but accept the risk that there may be no payment.

Notch? What notch? I have an iPhone X and mine has ears which extend the display up into the top of the phone where the camera is placed to get my status bar out of the screen. Brilliant! I say.

Sure they have. It’s in the iPad, though it only supports two application level windows the applications may tile within themselves.

The good news is that sine wave inverters are no longer expensive in the context of an off grid system. The bad news is that they seem to idle at about 3% of maximum power capacity. This can easily be your largest energy consumer if you bui

They attempted to use it as a monoprop, where you pump it over a platinum screen to catalyze it. This is attractive because it avoids any issues with mixing. They had extreme difficulty sourcing anything but dilute hydrogen peroxide. The fe

Deflect most often is used in a sense of deflecting something away from something else. e.g. to deflect a bullet. That would mean away from its target, not into a target. In English there isn't a general word for altering a trajector

Starlight plus airglow is at least 6 orders of magnitude below sunlight. Granted, it goes all night, but it seems like 4 watts per square meter is still 3 orders of magnitude above photoelectric gathering of starlight. That 4 watt number co

I spend summers in a seagull rookery on a small island, about 2000 adult birds. Each pair averages about two young. A few years ago when the young were hatched but still tiny, puffy balls with legs there was a strong wind for two days. One

The article suggests these towers are being built in blocks of lower buildings. Each block has a "allowable total square footage of building" limit. The developers are buying lower buildings, or unused area rights for lower buildi

To elaborate… the pilots' union doesn't want the airlines shifting jobs to lower paying affiliate airlines, so their contracts restrict the sorts of planes which can be used with the affiliates. Covered in wikipedia: https:/

Only about 5% of the Sun's energy, as filtered by Earth's atmosphere, is ultraviolet. You can block it all with negligible efficiency loss at your solar panel. I'm not sure about UV filters that will be stable for 1000 years.

Yeah, there are little plastic chutes in the fence for feeding them. I noticed those after I successfully and painfully retrieved my right coding hand from inside the head of one of those nightmare birds.

I presume port space on the west coast is in high demand for receiving goods from Asia. Also, if I were proposing to tear apart a ship, I'd rather deal with the EPA in Texas than any of the west coast states.

The author is concerned about the embodied energy cost of a larger battery, so has a smallish battery which only lasts about a day. For my small solar powered installations I generally use a lead acid battery with a zero embodied energy c
