In thermodynamic terms, an air conditioner is a heat pump hooked up the other way, though in practical terms I realize a heat pump is a device that is used for heating. While not as mathematically elegant a comparison, you could certainly r

Modern heat pumps can get a coefficient of performance of around 3, meaning that for every watt of electricity going in, you get 3 watts coming out inside your home (the other two watts are being removed from the air outside). For everythin

I think it's worth looking at how deplatforming happens here. Whether it is someone being fired or a tweet deleted or a community banned, the "cancellation" is almost always done by a company. Companies operate more like amor

The business codebase I'm working on now was written by OOP crazy people who thought inheritance was the solution to every line of duplicated code. When they hit roadblocks, they filled the base class with things like if(this.GetType(

Most developed nations have highly regulated healthcare systems, and part of the government involvement is in setting prices. The U.S., through everything from safety regulations to IP laws to insurance regulation has destroyed competition,

Earn a living is taxed. Groceries and clothing are taxed (in my state at least). Homes are taxed. Investing your hard earned savings back into our economy is taxed. Getting a large sum of money from your extremely wealthy parents is also ta

A very cynical answer to what's the logic here: objective measures get in the way of many non-academic college admission goals, so colleges want to do away with them. One of those goals is racial diversity, and that's the only one

James Gunn, director of "Guardians of the Galaxy" is the first person to come to mind for me. He's not a stand-up comedian per say, but humor was undoubtedly part of his job and he got fired for some very poor jokes he made o

There may not be an analytic solution, but solving the n-body problem numerically with newtonian physics isn't a difficult thing to do...it's simple enough that it has been used as a benchmark for doing computations: https:/

In addition, that up and down motion is annoying to passengers, and a waste of energy. The suspension has dampers, and the tires have hysteresis (it takes more energy to squish a tire down than you get from letting it spring back up), so mo

And so the difference between May and June futures should be constrained by the cost of storing oil for a month (the price of oil for June should be <= may + 1 month storage). Of course, storage facilities take time and money to build an

I believe adc is still commonly used as a way of reading the carry bit. For example, assuming eax has already been zeroed, adc eax, eax would be the idiomatic way of reading the carry bit into eax. The carry flag gets set by all sorts of in

Amusingly, the introduction to "Seven Habits" starts off arguing against a hollow "personality ethic" approach pushed by other self-help books. I could be misinterpreting, but I believe that this is Covey insulting &quot

My last newegg experience was ordering parts for a computer with the free shipping option (2-10 days?). Power supply hadn't shown up 6 weeks later, so I tried to do an online support chat. Sat in a queue for 2 hours before it crashed.

Fashion isn't the best example for this, because often people are paying for prestige more than quality. A $3,000 purse isn't 100X as good as a $30 purse; the exclusivity of a brand that expensive is the attraction. People who opt
