The vastly preferable situation was to have redundant wiring that properly complied with regulations, which was retrofitted in an airworthiness directive (safety recall) after the accident. They also required engine software that detected t

Like Boeing, there was organizational dysfunction leading to a direct safety issue. During the development of the A380, the German and French sides were using different versions of the CATIA PLM software (i.e. CAD), which prevented people f

Philips Hue. I've had issues with color ones, the White + Ambience ones are fine. (Makes sense as they omit the color section) Hue is basically the only bulbs not being sourced from the same couple of white label manufacturers. Philips

Lighting color is cultural. Go to Asia and you'll find many places, commercial and residential, lit with 5500K, traditionally fluorescents. I've heard a theory that it has to do with genetics and lower eye sensitivity.

Had a ton of issues with the original Cree bulbs. They underglued the glass bulb and it came off with thermal cycling. They also put the LEDs on a metal core PCB they bent into ~10-gon tower. On the bends, the traces apparently would crack

My OG gray Philips lasted more than a decade constantly on. It was still working at the end but I noticed the yellow remote phosphor plastic panels were disintegrating with a web of cracks. Underneath, the plastic surrounding the LEDs had t

Incandescent bulbs are 0.8 atm (equivalent to 15,000 ft altitude) when off, and when they're on, they're actually slightly pressurized.

You need 1.25 kg of gas. Candles don't consist solely of oxygen, the ones the Russians use utilize lithium perchlorate (LiClO4). When they finish burning, you are left with a lithium chloride ash (LiCl), which will be 40% mass of what

Candles are useful when oxygen has been consumed because of respiration or a fire. They're not useful in a leak. Conservation of mass: if a cubic meter of air escapes, that's 1.25 kg, and you need at least that much in candles. (Y

Because it's not an actual investment and can't run out. Like US Social Security and many other national schemes, the UK is pay-as-you-go. Money coming in is immediately paid out. Any funds lying around are supposed to be for temp

You don't have it "now" unless you didn't upgrade to 26.3. But yes. The only way you can resize windows through System 7 is the resize widget. You cannot grab anywhere else and drag. They couldn't afford the extra c

Logistics requires lots of humans, and worse, humans traveling. That's inherently risky and a difficult physical job. People simply would rather have an information economy job like a software developer where the danger is a severe cof

It's a thing, but it's not universal on the A320. Original 1984 critical hardware: the box has an EEPROM module, you swap it on the plane. FMS (which requires monthly nav data updates) and all modern hardware: the box can be updat

Not true. 7th gen gained Mode Based Execution Control which greatly decreases the overhead of VBS. 7th gen also gained SMM Security Mitigations 1.0 and some UEFI hardening.
