Apple neglecting MST is so frustrating. My MacBook Pro could do MST with no trouble in Boot Camp which adds insult to the injury.

A380 is also quite a fuel-inefficient plane. It optimizes for passenger load per aircraft seemingly at the expense of everything else.

We looked at using these in a previous job that had a very tight tolerance on RF frequency tolerance. Vibration tolerance makes the use of crystals difficult. Unfortunately, the phase noise of this device wasn't good enough to be the f

What you're looking for is Trust Vector Control(ler). Most modern rocket engines physically gimbal the engine around with ~two linear actuators around a fixed point at the top of the engine. All of the plumbing and connections to the r

I still have this problem where my mom's iMac will occasionally send a SMS (sent via macOS Messages and delivered via her iphone) to the email address in my contact, rather than my phone number. Somehow it thinks that xxxx@yyy.com is a

Thermally, the helicopter cannot keep itself warm through winter due to decreasing solar power generation. Over the next few months, as the solar generation goes down leading into winter, the energy available for flight (rather than surviva

You've brought up the key piece here, the scope of refurbishment. If engines become a Ship of Theseus problem, then it compromises the idea that age proves a particular engine serial number reliability. I think there's a differenc

I think saying they're 'super-reliable and battle tested' is a bit strong. The SLS program has been plagued by engine problems in the last year. They've already replaced at least one fuel (preburner?) valve, and had issu

I gave up on reporting bugs to Apple a while ago. The experience, repeated several times over, of spending all the time to file a radar, gather all the logs and files that Apple insists on (probably reasonably), then submitting the thing an

Oh goodness I thought this was just me after searching online and finding very little, if any, discussion of the bug. The issue I had wasn't on password login prompts, but on account creation prompts (i.e. password+confirm password). I

There is truth to this in aerospace: components will be qualified to the design life of the vehicle, but the qualification campaign is intentionally conservative to envelope all possibilities and uncertainty. When the actual conditions are

People lose money in the stock market all the time. This feels similar to me--people bet on the market and were on the wrong side of the trade. I do have sympathy for people who are having financial trouble as a result of their decisions he

'People' can simply choose a different electricity retailer if they want a constant rate and to not worry about this. If they were adequately informed about risks, why shouldn't we be allowed to choose our path? Industrial cu

Semi-related: I don't know about this image in particular, but many images taken off-Earth have their white balance adjusted so they look the way they would under Earth lighting. I'm aware this is done frequently for images from M

The helicopter doesn't have enough power generation to stay warm through the Martian winter; the solar panel that feeds it is extremely small, so at the very least, it is unlikely to last beyond the summer. Here's the thermal desi

Careful what you look at. The relevant number here is the RTT-SPP level from your link (not RTM-LMP), which then shows $9000/MWh everywhere in Texas.

Newpipe is the first video player I've found which has a trim-silence feature. I use the similar feature for (audio) podcasts all the time and according to pocketcasts, it saves me huge amounts of time. I've enjoyed having it for

I couldn't find it in the article if it was addressed, but I'd like to see 2017-era microcode used in the mitigations=off testing as well, to see how much of a difference that makes.

If I understand your point correctly, I think what you're describing is "engineering". This deep thinking seems like 'science' to me, while putting together those pieces of theory into new and exciting practice (pro

I think you're overestimating the difficulty of moving 500A. As GP said, liquid-cooled cables are the solution and come in reasonably-sized cable thicknesses (CCS form factor). This is ITT Cannon's product as an example: https:&#

True, however this is a far smaller variation ("several tens of percent" [1]) and only happens slowly (~once per day). This is in contrast to gas turbine peaker plant with can ramp by 10-20%[2] of rated power per minute. [1] https

Specifically your point about bunker fuel, this is now out of date a bit. The International Maritime Organization rules about ultra-low sulfur fuels came into effect 1/1/2020. Ironically though, this just affects sulfur, and so wh

Definitely agree. However, the long tail will likely include discovering some more 'improbably' results. For example, the researchers who ultimately discovered Phosphine on Venus this week had early requests for observation time o

One answer is to stack 3 LEDs on the die, each tuned to the center wavelength of human photo-receptors. Existing RGB LEDs emulating "white" suffer from shadowing effects where shadows have a color based on the parallax between the

No change. Just because your radio is "software defined," doesn't change physics and signal processing math. There are 'best' ways to use a given piece of spectrum, and while a SDR can make your hardware more flexib

The piece that always bothered my about Airbnb is how it incentivizes hosts to cheat in small (but not insignificant) ways. If my only recourse for not-as-described when I've arrived is to accept the keys, or abandon the booking, that&

Definitely the peak would be higher. My laptop has a ~60Wh battery and gets ~6hours of battery life, so I was just assuming 10W average for web browsing.
