And memory. In the heyday of ATM (late 90s) a few megabytes was quite expensive for a set-top box, so you couldn't buffer many seconds of compressed video. Also, the phone companies had a pathological aversion to understanding Moore&#x

It’s nontrivial why it’s mc^2 and not 1/2 mc^2, since kinetic energy generally is 1/2 mv^2

It’s lucky when you can get the sign right on the first-order effects. Predicting 2nd order effects accurately enough to price them is economic voodoo.

Comparing fighter pilots to helicopter pilots might say something about the effect of G forces, since the cognitive loads are both high. However, the control group is “10 adults with no experience in flying … matched for age, gender, and ed

I find "this wasn't the point of copyright", referring to the motivations of 18th century legislators, unpersuasive. They were making up rules that were good for the foreseeable future, but they didn't foresee everything

Added fructose seems bad for you. Specifically, a high ratio of fructose:glucose (which doesn't occur in nature) does something weird to your metabolism. Your gut uses some hack like detecting only glucose to trigger intermediate steps

The relevant comparison is the energy needed to turn asteroids into food vs. the energy needed to turn exhaled CO2 and poop back into food. Astronauts live in closed ecosystems, so you don't need to bring in additional mass. Just close

Most bread and yogurt in the average grocery store is pretty bad stuff, full of HFCS, hydrogenated oils, and hydrolyzed proteins. But yes, I'd rather have a classification that clearly separates Coke and Cheez Doodles from actual foods

People only have to think about property pricing every several years, when they move. Electricity spot prices change by the minute. So the mental burden is quite different.

The list of examples isn’t very compelling. Extensions should be things that can’t be done in Javascript.

Your phone knows how often you normally use it. It could do something intelligent based on a usage pattern to restart when there’s an unusually long gap. I can see this being too hard to explain compared to “reboots after 72 hours.”

Don't let recruiters drive your career. Apply for jobs at companies you want to work for, and ask friends in the business to refer you.

PTC (positive temperature coefficient) thermistors do that. https://en.wikipedia.org/wiki/Thermistor . They’re used as auto-resetting fuses in many devices.

You could store all the data on the satellite, upload new code to process it differently, and download the resulting image. Then, the communications link just has to handle code (several MB up) and images (several MB down) instead of petaby

The sad thing is that none of it is very amusing. Current events twitter is more aggravating than amusing. We're aggravating ourselves to death.

If you have 2 periodic waves of amplitude a1 and a2 coming from different directions the peaks combine at every intersection, so there's always a grid of a1 + a2 double-peaks. If the wavelengths are around 100m, there's a double-p

I haven’t seen someone confess to this type of science fraud. They mostly deny, say nothing, or mumble “I don’t know how that could have happened.” It would be a service to the world for someone to come clean and explain their actions and m

In your dequeue/circular buffer implementation, how is it able to grow the queue without locking? The code seems to rely on atomics for head & tail, but grows the queue without any special provisions I can see. https://g

Fossil fuel plants are chemical -> heat -> mechanical -> electrical. The heat -> mechanical step is the inefficient one, sadly limited to ~40% efficiency even with very fancy machinery. Most other conversions can be above 90% ef

That should have been done from day 1. Now, however, there are 1000s of doctors who make fat stacks prescribing CPAP machines, and they'll fight tooth and nail to not lose their whole business.

The ROI of security is too noisy at a single company where you (hopefully) get less than one incident per year. But across the industry there is enough data to estimate ROI of various procedures.

There's no way to design vehicles that can't be made unsafe by a mechanic making a mistake. Even for purely mechanical things like brakes, a mechanic can leave out a bolt or crack a structural member so that it breaks on the road.

In software, most people dislike most other people's work. I wonder how much that varies between fields, or if it's been studied systematically. It might be pleasant to work in a field where you'd enjoy most other people&#x27

An editor feature I'd like is that as I'm typing an identifier, a hover popup shows me how many other instances appear in my codebase. It should be easy to build a map of identifier->count for instant lookups. I generally know
