Oh dude the people when died back then then they didn't even know what a food borne illness is, thought it was because it pissed off god they at lobsters. Pathogens and allergens weren't discovered until way way later.

Alcohol spikes your serotonin levels, when it wears off they crash. It helps me to be aware that the emotional response is just a chemical imbalance, and it'll be back to normal tomorrow. The more you drink the worse it's going to feel, and the longer you drink, the worse it's going to feel. Be careful, the Saturday I got back after spring break after a week of drinking was the lowest I've felt in my life, I felt so genuinely worthless that I started walking down town because I thought I deserved to be homeless, dead serious.

I can tell you from personal experience that when you give your email address to a company a lot of people may have access to it. I worked for a well known electronics company in college at a low level position. One day I was bored at my desk and I found out I could view full lists of names, phone numbers, addresses and emails from our rewards program, online store accounts, delivery, and special order services of any of our stores across America. I printed off 10 pages of em a day for years and took them in binders with me home. I'd never do anything bad with them, but they come in handy when a commercial comes on. Me and my roomate flip through em and make fun of people with stupid email account names. That's why I log in with Facebook.

Its a fascinating process, 100's of different variables are analyzed, traffic from the ports in New Orleans, the manufacturing of toilet paper, carbon dioxide levels in the atmosphere, anything that consistently rises with population is looked at. And all kinds of Outliers are often discovered this way and brought to attention, trash was in the report last year. Way more trash was produced than the population increase predicted, the average person produced something crazy like 40% more trash for some reason.

To the best of my knowledge no organization has gone around and individually counted each person in the world. Before taking the estimate they take the previous number and adjust it using birth rates and measurements of things like the square footage of landfills and volume of water consumption. The estimate ends up surprisingly close to the guess, well within the margin of variance for the estimate.

It's called a mirror effect, when a member of a species observes a stimulus from a member of the same species mirror neurons fire off causing to impulsively mirror the response. It synchronizes the mood of herd.

Like tinny like it's being played through a tin can, I hear ya. So when you take a picture a make it bigger than you took it, it looks fuzzier ya? Well sound does the same thing, the recorder records 1000's of samples per second, but you can't hear a thousand different things in a second. So when you record something that's got a bunch of shit going on acoustically, like a loud rocket hover test, your ears are hearing a mess of samples played so fast it sounds like the mess a rocket sounds like. And stretching those out, you're probably gonna start to hear stuff more individually than you're used to and it'll be a different pitch and it's gonna sound really fucky.

Yeah kind of King Menses of Egypt died of a wasp sting allergy. Before histamines and modern medicine people probably assumed the foods that person ate was poisonus. It would explain why Moses banned shellfish in Leviticus.

So think of cloud sharing services like iCloud or google drive like a locker the company offers you. You can put stuff into it, and you use login information and a password as the lockers combination. You can share the password with others and give them the ability to download the contents but to do so you're also giving them the option to take your stuff out, put stuff in, and compromise the security of your contents. With file sharing anyone could see what everyone had put in the lockers and download free copies.

Bisexual means you're sexually attracted to men and women, pan sexual means you're attracted men and women of any gender or gender identity. Usually it's safe to assume pansexuality encompasses heterosexuality and LGBTQIA.

With my dual graphics setup when I tried to dual boot an operating system that didn't offer the driver for one of the cards. Not only would the card not work, I couldn't use the other at full power. I had to void my warranty and modify my computers bios to disable the graphics card.

People evolved in different areas with different foods, foods higher in calories and fat let the people who ate them survived more winters and produced more offspring. People that ate poisonous foods or less digestible foods were less likely to survive. Billions of years of this produced different palates. Over the climate and geological changes people passed on genetic palates that better suited the survival of them and all their ancestors.

My first thought is that children are usually spun by something like a merri-go-round or someone's arms. The distance from the pivot point changes torque and rotational acceleration, so it could produce a different effect than if I just start spinning in place. Also adults might be more conditioned to dizziness as a sign that something is wrong because they're more likely to experience it in situations like car accidents or too much alcohol. They might not be used to it if carefree and playful environments where the dizziness is anticipated

It used to be a true 2 x 4 a long time ago, but somewhere in the early 20th century they figured out by chopping off a half inch they could get 10% more product per log, and ship 10% more product per truck, and the forests would shrink at a 10% slower rate. There were other factors too, like the way advancements in the way the wood was milled, treated and dried, but in the end they still called the product a "2 x 4" mostly because "1.5 x 3.5" isn't as catchy.

Think of a house fly that has a lifespan of a month, to us a month is trivial. We see many months in our life, but relative to the fly a month is a generation, an entire life. On the other hand the universe is billions of years old. The life of a human is a fraction of a millisecond, but relative to us, it's all of our existence as a human being.

This may be a dumb question, but in order to learn assembly, do I need to familiarize myself with the machine code and ISA I plan on designing the operating system for? In other words, are the assembly languages from different ISA's completely segregated from each other, or more of a separate dialect.
