People who bought things in bulk (also known as buying in gross) to subdivide and sell in smaller portions, became known as grossers, and eventually grocers. Eventually, the word "grocery" came to mean the actual goods sold by grocers.

Yeah, I'm not disagreeing with you. I am focused on the aggression in particular: trying to flip things around to where the defense is a counterattack. Which could be OK in some instances, but the post itself equates having other interests (like, uh, socializing in person) as cheating.
Elsewhere in this thread OP is condescending towards "sportsball" and "clubbing," which reinforces my point that he's not talking about defending his own hobbies and interests, or even attacking judgy people who should mind their own business, but more interested in attacking others for having hobbies and interests inferior to his own.
In my eyes this is all cringe for those reasons.
I'm not a fan of judging/shaming others for their hobbies/interests, so it always makes me a bit sad when the defense mechanism is to try to flip the aggression on the other side, trying to shame the "normie" interests.
every hole is a goal

25-35 is a great time. I moved cities and changed careers in my late 20's, and pivoted again in my early 30's, and it was a good reset to build on lessons learned and undoing past mistakes, while having the youth and energy to really enjoy myself and actually choose a path I was going to have fun with.
I'm enjoying my 40's a lot, but I look back fondly on that 25-35 period as being both fun in itself and setting me up for a good 30's and 40's (and possibly further).
I can't answer for dual numbers, but I can answer for imaginary numbers in circuit design.
Imaginary numbers are those that include an imaginary component, that squares into a negative number. Traditionally, i^2 = -1, but electrical engineers like to use j instead (I tends to be a variable used to describe electrical current).
Complex numbers, that include a real component and an imaginary component, can be thought of as having an "angle," based on how much of it is imaginary and how much of it is real, mapped onto a 2-dimensional representation of that number's real and imaginary components. 5 + 5j is as real as it is imaginary, so it's like having a 45° angle. The real number 5 is completely real, so it has a 0° angle.
Meanwhile, in alternating current (AC) circuits, like what you get from your wall outlet, the voltage source is a wave that alternates between a maximum peak of positive voltage and a bottom trough of negative voltage, in a nice clean sinusoidal shape over time. If you hook up a normal resistor, the nice clean sinusoidal voltage also becomes a nice clean sinusoidal current with the exact same timing of when the max voltage matches up with the max current.
But there's also capacitors, which accumulate charge so that the flow of current on the other side depends on its own state of charge. And there are inductors, that affect current based on the amount of energy stored magnetically. These react to the existing current and voltage in the system and manipulate the time relationship between what moment in time a peak current will happen and when the peak voltage was.
And through some interesting overlap in how adding and subtracting and delaying sinusoidal waves works, the circuit characteristics line up perfectly with that complex angle I was talking about, with the imaginary numbers. So any circuit, or any part of a circuit, can be represented with an "impedance" that has both an imaginary and real component, with a corresponding phase angle. And that complex number can be used to calculate information about the time delay in the wave of current versus the wave of voltage.
So using complex phase angles makes certain AC calculations much, much easier, to represent the output of real current from real voltage, where the imaginary numbers are an important part of the calculation but not in the actual real world observation itself.
So even though we start with real numbers and end with real numbers, having imaginary numbers in the toolbox make the middle part feasible.
I’d rather read twenty minutes than watch a 5 minute YouTube video.
Part of the reason why I have no patience for video as nonfiction is because I read a lot faster than videos (or audio) can communicate information. So for me, I'd rather read a 5 minute document than a 20 minute video, even if one is literally a transcription of the other.
At least with audio I can take that in while doing something else.
The 787 has 8 main tires and 2 nose tires. The main tires are 218 lbs (about 100kg) and the nose tires are 114 lbs (about 50kg). So a set is roughly 1970 lbs/900kg, pretty close to a short ton. 5 metric tonnes would be about 5.6 sets of 787 tires.
Hallucination feedback loop
It's not about work ethic. It's an openness to new things, and a willingness to coordinate and plan things.
And seeing "moving away" as a huge sacrifice, to where you'd tend to describe it as "uprooting your life," is a particular worldview that you're entitled to, but one you should be aware that many other people don't share.
You're attributing a lot of unspoken values in that comment that I don't really think are there, and I suspect it's because you place a much higher value in staying close to home than the typical person does, and because you seem to elevate the purpose of a career to primarily be maximizing one's own money.
So take a step back. Reread that comment with the revisited assumption that some people choose careers for reasons completely different from money, and that people don't feel a strong need to stay in the same city where they grew up. It's just career advice at that point.
There's more to careers than just money. The distribution of jobs in different industry sectors, job specialties, etc. aren't going to be uniform throughout the world, so many types of jobs will require people to move.
It's not even about money. It's about wanting to work in something specific that isn't as easily available in the town you happened to be born in.
that's insanity
makes me feel sick
That's a pretty strong reaction to the simple idea that maybe living your entire life within a 30 minute drive of where you were born isn't the best way to experience this life. You don't have to want it, but is it that much to ask to simply understand that some other people want it?
My hometown is, like, fine. I could've stayed. But its state government is insane, the dominant local industries and companies don't really fit my moral framework, and the social aspect pushes people into a car-based lifestyle that I'm not particularly interested in. I left for a job, but I also was just looking for a reason to leave.
Lazard is a pretty respected analyst for energy costs. Here's their report from June 2024.
In the U.S., peaker gas plants that are only fired up between 5-20% of the time, the levelized cost of electricity (LCOE) is between $110 to $230 per MWh. The levelized cost of storage for utility scale 4-hour storage ranges from $124-$226 per MWh, after subsidies. Before subsidies, that 4-hour storage costs $170-$296.
Residential storage, on the other hand, doesn't come close. That's $882 to $1101 before subsidies, or $653 to $855 after subsidies.
So in other words, utility scale storage has dropped down to around the same price as gas peaker plants, in the U.S., after subsidies.
And yet, people do.
Should we just ignore the dynamics of that system, and pretend it doesn't exist? Or can we make observations about that system, and analyze its effects?
This comment section is all people missing the point.
The point of the post is that a particular job will generally stabilize at a particular pay. If it's a tipped position, then the employer will pay less, so that the overall income is roughly at that stable income for that position, including the overall average tip.
So people who tip less than the average are free riding off of the people who tip more than average, where that worker will make an average tip overall, which comes more from the generous tippers than the stingy tippers. Thus, it effectively transfers money from generous tippers to stingy tippers, on net, in the long run.
The merits of this system, whether servers deserve to be paid more, whether we should push for reforms so that this isn't the system, is besides the point. The post is making an observation of how things actually are, not advocating for how things should be.
It's just that I don't have any expectation of the girls in the picture being shocked
That's the joke.
Yeah, people are working on it.
The EIA estimates that there's about 30 GW of battery capacity in the U.S., mostly in storage systems that are designed to store about 1-4 hours worth.
That's in comparison to 1,200 GW of generation capacity, or 400 times as much as there is storage.
It's coming along, but the orders of magnitude difference between real-time supply and demand and our capacity for shifting some of the power just a few hours isn't quite ready for load balancing across a whole 24 hour day, much less for days-long weather patterns or even seasonality across the year. We're probably gonna need to see another few years of exponential growth before it starts actually making a big impact to generation activity.
Most recent studies of long term ketosis show accelerated aging markers, and some potentially harmful increases in LDL and VLDL cholesterol. Some propose periodic resets out of ketosis to avoid some of the accumulated long term issues, while taking advantage of some of the short term benefits for overall insulin sensitivity and obesity.
The human body has many, many ways to meet its nutritional needs. We're omnivores and we have lots of anthropological history of different cultures surviving primarily on carbs, primarily on animal products, and all sorts of in between.
There are plenty of issues with people on carnivore diets, too, so I would caution against trying to swing the pendulum too far in the other direction. I've never seen anything suggesting that there's a statistically significant delta between a high carb whole foods diet and a low carb whole foods diet. And even within those frameworks, it's entirely possible that the qualitative differences between one whole food still makes a difference compared to another whole food, like the observed studies regarding red meat being bad, fatty fish being good, legumes being good, fermented vegetables being good, etc.
Nutrition science is pretty incomplete. We're only recently learning bits and pieces about the role of the microbiome, and haven't even finished accumulating the information we started learning in recent decades about endocrine feedback loops in nutrition and metabolism. It'll take a lot of data and analysis to have confidence in what people are saying, and I personally take it all in with interest but skepticism.
