Efficiency is not everything when it comes to nutrition.

Once someone is beyond being able to procure enough food to survive, utility is important to quality of life and long term health.
What sort of utility?

1) Total caloric intake depending on if the goal is maintenance, weight loss, or weight gain.

2) Macronutrient split depending on specific health and/or performance goals. E.G. high protein for strength trainees.

3) Micronutrient split and density for general health and/or to correct deficiencies. For example, many people are Vitamin D deficient.

4) Mental health. An extreme approach to diet can create eating disorders and may lead to social isolation.

As with most things in life, there is a cost/benefit equation associated with nutrition choices, and focusing purely on efficiency most certainly has its costs - some of which are not obvious. Those costs can have a negative impact on short-term and long-term health. Health is easy to take for granted - until there’s an issue.

The point of my post? I hope that the takeaway from this article isn’t: “make cost efficiency your primary goal in food selection,” but rather, “carefully evaluate your specific situation, establish nutrition goals, and treat food intake like a solution to a problem - just make sure the problem(s) are very well defined.”

This advice applies to those that have the discretionary funds to facilitate this level of selectiveness, which I’m guessing applies to most people reading this.
My upstairs neighbors in the mid rise apartment I lived in raised chickens on their porch, was fairly normal to have one wander down to my deck. I don't have a point other than to point out these days chickens are not a signal of the sticks.

As a 2 sigma gifted kid (I guess), I had some of this same tendency, starting around the same age as your son and becoming all but unbearable my freshman year of college. It took me another 15 years or so to develop the emotional intelligence to cope more effectively with the trauma of existence.

The one thing I wish I had discovered earlier, was Buddhism. Not as a religion, but as a mental practice, and an existential framework. Some of the most profound insights I've gotten about existence have come from Buddhist writing and teachers, and with all due respect for other religions, these insights seem uniquely Buddhist. Other religions do touch on the same topics, but either more obliquely or at a more esoteric/advanced level, whereas they are foundational to Buddhism and often stated in a very plain and concise manner.

For instance, that inner pain your son feels, that makes him want to die? That's the unavoidable discomfort of existence, which is literally the "First Noble Truth" of Buddhism. And if we look deeply enough, we can see that we simultaneously crave both existence and non-existence: we want to live forever but often can't bear the immediate experience we find ourselves in. We torture ourselves with contrary ideals that can't possibly coexist, and it's not like we even have any choice in the matter anyway! Gifted children are not unique in this regard; only their precociousness and sensitivity to it.

I could go on, but my specific and personal lessons aren't all that relevant. Aside from the existential framework, the main thing I hope you do for your son, is to give him the gift of "___". Normally Buddhist advocates would say "meditation" in that slot, but I prefer to put it like that, because while I would personally recommend the practice of meditation, that's not the only method of getting this value. Alternative words are prayer, silence, breath, sitting, peace, stillness, non-judgmental self-reflection--these are all part and parcel of the same core skill. Which is the cultivated ability to receive the experiences of life, as wonderful or as terrible as they are, with equanimity, knowing that the experience is the point and this too shall pass. All other aspects of emotional intelligence stem from the metaskill of being able to "sit" with the profound and inescapable discomfort of one's existence.

Best of luck to you and your son. I don't envy either you or him, but ultimately it just is what it is and we all end up in the same place anyway. Hopefully this helps make the journey a bit easier.

Not all “Classic Macs”. MFS, the file system used on the original Macintosh, didn’t support subdirectories (the folders that the Finder showed were illusions created by the Finder) (https://en.wikipedia.org/wiki/Macintosh_File_System), so it didn’t have path separators.
git is super hard, because it has too many sharp edges.

Quick quiz: What does 'git checkout a/b' do? I've seen users end up with 3 different meanings.
So Windows forbids other characters in names besides the directory separator?

It's not a dumb question at all - it gets beyond most undergraduate classes on computational complexity. What's interesting is that the algorithm presented for this problem is exactly one of those classes: the quasi-polynomials, which grow exponentially in a polynomial of logs of x.

It all depends on the goal right? In this case it seems the goal was to harm the company because they didn't pay ransom. Not to perform long term espionage.

I find it very confusing that you seem to use "real number" and "floating point number" interchangeably.

Like this:

> The DFT over the reals is not lossless. Using floats, for example, and applying it to max_float overflows, so cannot be inverted.

I don't see why you make statements about the reals based on what happens with floats. They aren't the same, and the DFT exists independently of actually computing it.

This is fine except for the low-cost carbs. These have high glycemic indexes and glycemic loads. That means they cause insulin spikes in your bloodstream, which causes type 2 diabetes. And no, that is not just my opinion, it's the research-proven scientific consensus.

It's better to get your carbs from beans and also calories from healthy oils like olive and canola.

You realize that fiber isn't a valuable nutrient, right? Your body can't break it down, and it passes through your digestive tract pretty much intact.

Fiber makes you poop because your body is literally rejecting it.
This page, like all FIRE stuff, is making rather positive assumptions about the ROI on savings (they’re assuming 5% over inflation). I, for my calculations, am personally assuming 0% growth - I just don’t want to end on a street when I’m 65 or 75.

I agree it's not hard once you get it, but the main thing is people don't get it. It's unintuitive. That's not to say the model is wrong (I think it's correct), just that there's a huge gap between what people think git is doing and what it's actually doing and so they end up fighting it to do what they think it should do.

I had a coworker explain that he did a merge and something unexpected happened to his branch. I had to explain to him that what happened was totally expected and that his understanding was what was wrong.

Sudden release of such gases has been suspected in the case of a number of sudden ship disappearances over the centuries.

A first I thought this was a time shifting game like Braid, but this feels sorta like FEZ, except instead of a character learning about a 3D world from his 2D origins (which most people can understand playing SNES/Genesis games vs modern console games) into something way more bizarre that we can't even visualize.

Its not ridiculous. How can you "negotiate" when you have 0 leverage? There is no "negotiation", ever. Even calling it that is disingenuous because it implies that some low cost could be reached if it were not for those darn evil corrupt capitalists. To illustrate how absurd it is, think of a scenario in which a woman with a gun robs a jewelry store and then boasts she got a 99% discount due to her "negotiation" skills. The clerks have 0 leverage in that situation, so it is not a "negotiation" in any way.

The only option the company has is to sell. If they don't, they lose all their investor money and go bankrupt. The reason other countries get away with obscenely low prices is because the good'ol USA is paying for it, and the companies are better off getting anything other than 0.

If you look at how well industries are doing, you would also see that you would actually make more money investing in a burger chain than in the pharma sector. These high prices exist because of the incentives the insurance model creates (i.e. save people at any cost), not because companies are super greedy or evil and make 1.99$ million profit on a 2$ mill drug(which they do not).
To bring down the cost? I'm confused as to what you are getting at: are you trying to say that if a therapy of infants and children exists at some cost determined by the producer of the therapy that Medicare is obliged to pay that price immediately and perform that therapy on the affected infants/children? In my understanding, certain procedures already have to go through some kind of approval before being eligible to be covered by Medicare in addition to FDA approval (I might totally be wrong here). Medicare negotiating the price would be an additional step.

Update:

Replies (I reached the maximum nesting level):

'chimeracoder: Thanks! I appreciate it. I keep forgetting that Medicare only applies to seniors. I guess individual insurance companies or the parents of the affected infants would be the ones to try to negotiate the price of this treatment then.
I wish you talked about the product itself instead of complaining about SaaS models vs desktop software models. But FWIW you're mistaken about the pricing. There exists a similar tool in the chemistry space called ChemDraw. It's desktop software to visualize chemistry. And the cheapest version costs over $1,500 [1]. The more expensive version costs nearly $5,000.

Surely it ends when the corporate Credit Default Swap (CDS) rate rises, and credit rating drops, so the interest rate paid by the company rises when they have to refinance their bonds. Eventually, interest on bonds exceeds cashflow, and they have to borrow more to pay interest (Ponzi phase).

At the margin, the lowest investment-grade BBB company drops one notch and becomes High Yield 'junk'. Then insurance companies and pension funds with fiduciary obligations must divest themselves of the bonds, so they sell and force the yield (interest rate) even higher.

Companies have borrowed too much to perpetuate buybacks, jack up the share price, and reward executives with profits on share options. Half of all bonds are at BBB, just one downgrade from junk [1]. This situation is highly unstable, just one snowflake will create an avalanche of downgrades, and a true Black Swan will bankrupt many companies [2].

These companies have run off the cliff, and if they look down into the abyss, they will fall (e.g. GE [3], IBM). As with sub-prime mortgages, CDOs and MBSs during the Great Financial Crisis, pulling the trigger depends on the ratings agencies. Last time they were asleep, or perhaps complicit (euphemism for corrupt). Let's see what they do this time.

To be honest, I thought this already happened. Who wants to ride in a tiny cramped backseat?
I heard you can also contact support to separate this out too.

It's necessary to preserve issues and pull requests.
The best system seems to be to communicate honestly and openly, to be accepting of your partner's differences, to establish and allow personal boundaries, and to negotiate when boundaries seem to interfere with each other. So basically to have a healthy relationship.
It seems that the stock price (under the ticker FAF) hasn't suffered very much. This was revealed on 5/19, and the response has been tepid.There isn't likely going to be very much backlash on the stock, unfortunately.
I’m old enough to remember the bad old days but it’s a good point. I was specifically thinking of the post-MacOS, OS X (Panther and later especially) era.
The numbers are a "project programmer number", or PPN. The "project number" is like a bit like a GID, and the "programmer number" identifies the user within the project (so a bit like a UID).

A lot of early operating systems didn't have hierarchical directories. It was common to have either one single directory for the whole volume (like CP/M and DOS 1.0 had), or else a two-level structure in which each user gets their own directory but no nesting of directories is allowed. TOPS-10 PPN's are like that.
It's useful to distinguish between command line and GUI apps vs. the operating system itself.

Forward slashes and backslashes have been supported as path delimiters all the way back to MS-DOS 2.0 when hierarchical directories were first introduced. The DOS and Windows file APIs never cared which you used.

It was only command line and GUI apps that (rightly or wrongly) preferred one or the other. The only new thing here is that some of these apps have finally started to recognize either delimiter.

That is a tricky thing for a command line app where the wrong slash may be interpreted in a way the user did not mean. For GUI programs there was never a good reason to not accept both, e.g. in a file path field.
Privacy was my first concern about it, too. Okay, so maybe not worse than Manna, but at least as bad as, if in a different way.
As I recall, so could / would DOS - at the Int21 syscall level.

The SWITCHAR option was present to set a value which COMMAND.COM (and other DOS utils) consulted such that one could make it honour '-' as the flag leader, and then accept '/' at COMMAND.COM (and other DOS utils).

Unfortunately not all third party utils honoured that, and so it usually ended up not being worth flipping it in to Unix compatible mode.

That said, one could take advantage of the recognition of '/' in programs one wrote, e.g. C code (so avoiding "directory\\file.txt").

False dichotomy. We have robust public and private medical research universities.
Well humans aren't solar powered; it takes thousands of tons of plant matter and hundreds of tons of animal matter in order to sustain each human. And it takes hundreds of millenia of experimentation with the real world in order to create a world like the one we currently inhabit. If humans harness 100% of the Earth's solar energy to produce a population 10,000 times its current size, it would still be unsustainable. Likewise, an AGI would need to harness that solar energy to produce silicon wafers and to manufacture chips; it wouldn't dedicate 100% of its energy to thinking.

We don't see evidence of life on other planets, and certainly not any evidence of superintelligence gone awry; a planet filled with paperclips is in an extremely low-entropy state. Evolution can happen because human beings, despite being low-entropy beings, turn low-entropy things like bananas and apples into high-entropy things like poop and carbon dioxide. This delicate process is likely why humans are relatively easy to kill, and why a superintelligent AGI would be unlikely to overpower mankind's dominant position on Earth.

So the assumption that a superintelligent computer program could suddenly harness 100% of the Earth's solar energy and outsmart humans to the point where it can't be turned off is still a highly unlikely prossibility. The arguments in favor of AI danger are easy to make but likely wrong, the arguments against AI danger are complex, require lots of thought, but are most likely correct.
If the alternative is no cure at all, what's the issue?

If it's a fair price based on all their costs, then there's no issue. But if it is exorbitant even after considering all the costs- well, many people take umbrage with healthcare profiteering.
While I’m sure it works for the OP, I’m guessing most other options would work.

My take is that this approach just moves the discussion to what qualifies as “fun money” or should come out of the shared account.

Maybe it’s because we are too young yet, but me and my SO just have a shared account and contribute to it equally (she insisted, I wanted to do proportional). We make sure to put in there enough to cover the bills and some more to have some “emergency money”.

Aside from that we keep separate savings accounts and some investments.

Old, esoteric systems also require knowledge of the system, which can be practically impossible to get from the outside. This is why learning COBOL in 2019 probably won't get you a six-figure job maintaining old bank mainframes. You may know the language but if you have no clue how these bank mainframes work outside of using COBOL, you aren't going to be a great
candidate.
Yup this is the justification for why polynomial reductions should define everything within class, but it doesn't seem to justify why we should only focus on the polynomial and exponential classes to begin with, given there are infinitely many classes in between (and beyond exponential). Sorry my question didn't make it clear that's what I was asking about; I edited it to hopefully clarify.
