Oh I knew. I’d done a bunch of heroin and other opiates, even had fent patches before the whole fent craze started. But this was the first time I’d had pure fent and smoked it. Naturally I’m a dumb fuck who doesn’t believe all the stories and does stupid shit like overdosing twice in a week. But in my defense I’d done a lot of opiates never once had a near death experience cuz I was “safe” so I thought

Heh. I graduated in 2009 and we still had some assembly in my degree program. It wasn't even being taught in a specific CPU's assembly language at that point, they had invented some assembly-like language to teach us about registers, bitmath, and jumps but it was actually interpreted by a Java CLI tool that produced the output.

I think it was just there to teach us how good we have it working at higher levels of abstraction.

Imagine regular electrical outlets delivering electricity the way a garden hose delivers water. It’ll eventually get you enough. A fire hose delivers more water with more power because the hose is bigger and the pump is stronger. Charging a car is similar to a job that needs a fire hose to complete efficiently.

It's too simple to say "only traits that help survival persist." We have vestigial parts in our bodies, we occasionally bite our tongues, and succumb to genetic diseases.

All natural selection means is that a certain setup is generally good enough to reproduce. So if you remember that "B" and "T" in the initialism there don't necessarily mean same-sex relationships only, they would be able to pass on their genes just fine.

As for others, maybe they don't. Look at the straight people who keep having gay babies. :P

I think the numbers end up being about 5-10% of all mammals show homosexual tendancies/behaviour. As far as the other parts of the non-hetero community it's a bit tough to show that in animals you can communicate with.

Lots of things that don't seem to benefit survival show up in the evolutionary tree of life, so who knows really.

Nobody knows why homosexuality is part of all mammalian life, even some birds too I think.

It's also pretty juvenile to think of it as "beating" it.

A wall outlet is 120v. Yet EVs mostly use 480v induction motors.

Batteries are also direct current and power supplied in the grid is AC so you need to convert it either at the source (EV charger, or increasingly so the cars have an inverter built in)

Some EVs use AC induction motors so the conversion happens twice in some cars, losing a lot of energy as heat.

Yeah exactly, to both points. Learning how to do similar things under different paradigms is a great skill because it keeps you from getting too stuck on one way to approach a problem but learning all the available paradigms is mostly an academic exercise. You can learn the paradigms to identify their influences on languages but unless you're going into language design or academia they can be pretty esoteric. Not very many languages are purely single-paradigm. Most languages take influence from multiple paradigms and include features from those that designers like, creating fairly unique ways of expressing program instructions.

Example off the top of my head would be something like Scala. Scala adds features of the Functional paradigm to the Java language which is very Object-Oriented in its design. So if you're writing Scala you can write it like OO code, Functional code, or a mix of both. Scala idioms prefer Functional approaches so if you use those you tend to write less code and stuff runs better but you can also work with objects and gain some benefits of OO concepts like function encapsulation.

Python is another language that takes hints from Functional programming and OO programming, but implements its objects and classes very differently from how Java does it.

Just to respond to other comments - most people rarely use checks for day to day expenses. Our paychecks are direct deposited, and we pay our bills online or though our banking app.

Checks have their weaknesses, but at least your credit card number isn't being saved or harvested online. And you can be sure banks will call out a bad check. Credit card companies won't catch fraud for you and may not believe you if you claim unauthorized charges.

Yes, in America we often have to wait 2 days for checks to clear. It's because a lot of that processing and consolidation doesn't happen until banks are closed for the day. It's a system designed before the internet existed.

You actually do just plug them in - the charging components are all in the car. The fancy Level 2 home wall charger is just a glorified extension cord with circuitry that tells the charger in the car the maximum amount of power it's allowed to draw. This is an important safety feature.

When you plug in a normal cord, whether that's 120v in North America or 240v in other countries, the car will only charge at whatever rate the normal sockets in that country are rated for. The standard North American socket can provide 1.5 kilowatts, so cars delivered to North America will not attempt to charge faster than that on a standard cord.

When you want more power, you need a nonstandard circuit. Again talking about North America, we've got two different common 240v plugs: a 7.2 kW plug for electric clothes driers, and a 12 kW plug for electric stoves. How does the car know which of those you're plugged into? It doesn't. And what if you want even more power, so you get a hard-wired connection that could be as much as 20 kW? Now you can't just make assumptions about how much power the car can use without tripping breakers, you have to tell it what's available. Rather than trusting end users to always punch in the right values, we get licensed electricians to install a fancy extension cord that does this automatically.

Bank teller here. The kind of check fraud that I see the most often is that someone will steal account information, usually a business account, and then make fake checks using that account info. They will then deposit these checks. If it looks legitimate and the account has funds, bank tellers won't always look deep into the checks. Then the check clears and the person depositing it can withdraw it.
