I remember a take-home physics test in high school where there was a pendulum problem and I spent a full day trying to prove that x’’= ax is generally met by a trigonometric function. I eventually gave up, and was very surprised when I got

They also ‘refund’ the rating hit you took from losing to the cheater. I think it works pretty well.

The answer is Bluetooth dongles. I’ve got a Bluetooth to aux adapter in my car, and it works a treat. I much prefer it to when I had my (original) SE hooked up with a physical aux cord, since it doesn’t wear out from fiddling with it and it

Paper grocery bags give off gas when they rot, whereas the (smaller) amount of energy in a plastic grocery bag is carbon locked in a controlled landfill. I think there’s a strong argument for plastic bags being more environmentally friend

I deleted the app because it was too much of a skinners box for me, but it worked well. The mobile site on iOS works well, and I literally never get popup prompts or blockers guiding me towards the app. Perhaps those people aren’t logged in

Yeah, as a controls engineer I’ve worked on systems where the main requirement was not gain or phase margin, but a root sum square of the two. Nichols plots drive home the idea that it’s not really the margin at two discrete points that mat

Your data should always be stored in 3 locations: 1) Your primary computer 2) An external hard drive you keep at home 3) The cloud (Dropbox, google drive, etc) This protects you from device failures, cloud failures/lapse of service, th

So what about those young healthy people that interact with no one who’s at risk? I’m in my mid 20’s, and the best upper bound I’ve seen on risk of death for someone my age who is otherwise healthy is 0.05%. Not nothing, but comparable to 2

If someone was going to steal company info for a competitor, they’d do it before they gave notice that they were leaving. And they wouldn’t tell their current employer where they were going. This might catch extraordinarily stupid people f

I can see how it’d be a decent tool for plotting up a bunch of raw telemetry streams, but as someone who had to write a moderately complicate program in LabView once, I’m astonished they’ve scaled it up that far and very glad it’s not me wh

If your fancy computer model doesn’t approximately equal your back of the envelope calculation, that’s generally a knock against the computer model rather than the napkin math. Exceptions exist, but for a system as linear as this you should

Not software, but along the lines of cool engineering stories one of my favorites is this one about fixing 230 kV, many-hundred-amp, 10 mile long coax cable in Southern California. https://www.jwz.org/blog/2002/11&

And the reason you’d leave it out is because a PI controller is guaranteed to be stable with positive gains. Throw the D term in there and you have to start checking pole positions to make sure your system doesn’t blow up.

As a controls engineer, I’ve pointed people towards that series of posts more than once. Great explanations.

I find it pretty funny that Bloomberg himself is hidden on that list.

I understand the goal is not pretty pictures. But you're not using a hammer to remove random white noise from all your observations, you're using a scalpel to mask out completely predictable errors for very short periods of time.

From a first-principles perspective, it's baffling to me why this would ever be a serious problem. We know the ephemerides of all objects in Earth orbit, and they are traveling at a fast enough angular speed to not linger in an observa

The idea is that the repair vehicle needs to have it open in order to fix it, but IMO it’s some BS.

Citation? That’s the first I’ve heard of it and that’s a pretty big accusation.

And to be clear, that port is for charging-in only, not data.

I don’t think this is the right takeaway - the examples all had marketing as the second skill because the author wanted them to be people that the reader would recognize. This means that they needed people with a public persona, which lends

I want to build executables that I can pass around without also sending an entire environment. Crazy that’s not a native feature.

How many headphones do you have? I’d be surprised if it was more than 2. Just keep the single permanently on the end of the headphone’s aux cord and that solves all your issues in this comment.

I still use an SE but I really don’t get this complaint against upgrading. Just keep the dongle permanently on the end of your headphone cable, and use one that splits out to a lightening charger as well. I’m seeing one for under 10 bucks o

The answer, unless you want to check the price of commodities each morning, is to recycle glass and bottles anyway and let the recycler decide if it’s economically efficient to send it to the landfill or to reprocessing.

Many services offer credit monitoring for free, eg credit cards, CreditKarma. You don’t need to be paying for it to be eligible for the cash payout.

Yep, I did a 2to3 conversion recently and it got the whole project 95% of the way there. A 3to2 would be in theory almost as simple to do for most projects.

Your suspicion is right, as far as manufacturing goes. The real boon of this discovery is in designing lenses. For example, the authors have already used it to design a single-lens telescope for the first time [1]. I don't know much ab

I would argue that we have definitely scratched the tip, though there’s a lot more iceberg to go. To anyone interested in this, I would highly recommend picking up a copy of “Principles of Neural Design”. It’s a look at how and why brains o

Existential was the wrong word to use. What I mean is geared towards your second paragraph - that we won’t be locked out of space. Our current systems are in a pretty narrow range of ideal orbits which would get cluttered up. But there’s a
