Regular exercise has a hugely noticeable effect on my ability to concentrate and keep multiple mental plates spinning at once. However, it's not available in pill form last I checked.

You can do it anywhere, anytime, at any intensity. It's as easy as taking a walk around the block, or as challenging as 50 pull-ups. You control the difficulty, handicaps, and every aspect of the activity. Bonus attributes are it's addictive. Once you do it long enough, your brain will begin to encourage and reward this healthy behavior. Sometimes, it will even punish you for trying to skip exercise with negative emotions and nature's great motivator: shame.

The best TV infomercial for mental well-being would be a 72 point font that reads: "turn me off and get off your butt!".

EDIT: If you want some help or initial instruction, there is an app for most smartphones that can help you get started at any level. There are many variations of this type of app, but I like the "Johnson & Johnson 7-minute workout" one. You can customize it way beyond 7 minutes, and it has helpful video instruction and voice prompting. Link to homepage: https://www.7minuteworkout.jnj.com/
Growers / producers in states with medical or recreational are a good place to look, since they have a vested interest in not losing their license. Some companies publish lab results — because, like you said, the regulation hasn’t caught up yet and you don’t know what you’re getting.

Legally, unless a state has specific laws against it (TX maybe?), the 2018 farm bill made hemp and its derivatives legal. But then the FDA jumped in right away and said, CBD supplements aren’t legal without approval.

IANAL, but I think the FDA memo applies to producers; I.e., I don’t believe one could get in trouble for buying CBD oil, but someone could theoretically get in trouble for selling it, if they market it as a supplement.
My concern is that it seems to be touted as some kind of "wonder cure" for anything and everything. While I'm sure a lot of people have seen results in various areas it does set off my bullshit alarm.

I think every two years would work, just like the FAA requires Flight Reviews every two years. For those driving bigger vehicles like commercial trucks, they can have an annual “proficiency check.” If getting a car license were more like getting a pilot license, we’d all be a lot safer.

If history is any indicator, forcing people to live according to the whims of Others results in death and destruction. The coercive power required to get people to behave and the inevitable blowback that occurs when people are unable to govern themselves will result in a lot of both.

Not everyone is going to like the environmental jihad that is being suggested, and that’s a big problem.
Instead of junk food I go for super unhealthy but high-end food, rarely. A huge steak, excellent bar food, extravagant cake and baked goods - that sort of thing. Nutritionally bad for you in a way similar to junk food, but minus the mysterious lab-made stuff, and you get to have an aesthetic experience while still stimulating your monkey-brain.
I think it's more accurate than claiming they are eliminated.
Correct - this would be just like alligator farming. I never miss the opportunity to savor gator meat whenever I'm in Florida, but obviously this isn't wild caught gator. Who knows what it might have eaten last night? I don't wish to be dining on poor Jim Bob who may have blundered too far into the Everglades after a night on the town...

In fact, the only gator meat that can be sold legally is farmed gator.
To you and parent's points: I think Harari dwells on the this distinction so much because one "model" can be changed, and one cannot.

I don't know why you were downvoted, and I'm also not sure what the GP means. Does he mean junk food == enjoyment or does he mean junk food is fast, saving you time for enjoyment?

Going quasi-paleo, I learned how food is supposed to taste, and everything tasted better. Junk food also tasted better. Way better. Crazy better. Years later, I still remember 1/6 of a pretty basic Safeway chocolate donut tasted, and what I was doing at the time (physics club). It was the first junk I had had in months.

On the other hand, my life would have been perfectly enjoyable without it as well. A link between junk food and enjoyment... I'm not going to judge it, but I'll say life's better when that link doesn't exist. When my life was nothing but junk food, nothing really tasted good. It was all just bland; like I was feeding a habit more than having a treat. Junk food was an escape from life for me, because life sucked. In part, it was not under my control. But in maybe the greater part, it was, and junk food was one thing I used to avoid having to do anything about it and still feel 'ok'.

As far as time, if you're eating well, planning ahead is key. You don't need junk food to help you get things ready faster, because you've already cut up some fruits and veggies for snacks, or you've got a bit of last night's steak for part of your breakfast.

I actually wonder what the Kubernetes conformance suite is worth. For one I took a look at how OpenShift passes the conformance suite as it is much more locked down than stock Kubernetes (that's a good thing, I guess, but not exactly conformant). The answer is, they remove the restrictions before running the suite (https://github.com/openshift/origin/blob/master/test/extende...). So in my view a default installation of OpenShift does not pass the Kubernetes conformance test.

The fact that many software packages for Kubernetes do not run on OpenShift confirms this and challenges the worth of the Kubernetes conformance claim, probably for many other Kubernetes products as well. Afer all, what good is a conformance test when it doesn't ensure compatibility.
I find that to be highly doubtful.
Their world will be worse too, depending on societal changes maybe even considerably so.
Well, if you put your tongue on it, you'll obviously have a lot more distance to cover and a lot more fluid to handle the current.

Batteries in general are fairly safe because their voltage breaks down at high loads. The chemistry can only react so fast internally and is controlled by various factors.

Contrast this with capacitors, where there is always a general safety warning when handling them in live circuits. They have no limit based on chemistry.

You don't want to test a capacitor with your tongue. A capacitor has no other current limit than it's internal resistance, with a modern sub10mOhm ISR a capacitor can, for the briefest of moments, discharge at up to 14 Kilowatts, quite the upgrade from the 14 measly watts that your spit will handle. A 100 Millifarad Low ISR Cap can sustain a kilowatt of output for almost 0.1 milliseconds, at which point you'll likely regret the choice of mishandling a cap. (It's only 14 Joules but these 14 Joules will be moving very fast)
Definitely agree. And any of the following if you're physically able:

For my dad: I'll add in kayaking or canoeing (through a club, training with competitors), for my mom: rowing (same, again). For myself: mid-to-long distance running mixed with shorter sprints. It's also good for the knees if you look after your health, do it regularly, and wear proper shoes for the terrain and your body.

I bet you could, but you need more measurements and statistical analysis. Keep in mind that a lot of these astrological measurements - and a more notable recent example is the black hole visualization - are not based on direct measurements, but statistical analysis on huge datasets.
This is an old idea. When I was growning up in the early 80s there were lots of children's books titled "Living in the year 2000" or something. They all confidently predicted towing icebergs, along with moon bases and hotels in orbit.

On the surface it is not a completely crazy idea but the problem is always the logistics. Towing something that big (and constantly melting/changing) in one piece is always going to be difficult. The scale of the task is enormous.

We don't have moon bases or hotels in orbit yet. I don't have faith that a sizable ice berg will be successfully towed around the world any sooner.
It is bad because if browser uses too much memory then it swaps out other programs like gnome-shell to the point that you cannot use Alt-Tab because the code responsible for it got swapped out.

It would be better if poorly designed sites (for example newspapers or TV channel sites) were slow or displayed without images and iframes with ad rarher than situation when browser swaps out everything else to help this poorly designed site run faster.
My interest in all this started largely from a (currently stalled out) initiative to build a coil gun. Cuz they're also awesome. :-)

Like most grand theories of history most of this is only works as a result of approximation. For example, the Unification stuff appears to me to be pure garbage. There is no moment in history when people went from cleanly separating outsiders from insiders. The examples given are both wrong; Egypt was likely ruled by a dynastic elite that came from outside (a common pattern across many cultures in Asia throughout history); the Romans, ironically, are the ones who gave us the word "barbarian". People still rail about foreigners; cf. Brexit.

If there existed some form of global consensus across the English-speaking world on what the inoffensive version is, I'd be happy to abide by it. In the meantime, suggesting that people on a venue as global as HN have some sort of a responsibility to follow and observe the random cultural variations in whichever narrow bubble you were referring to strikes me as presumptious and absurd.

I also wish more people valued clear language over these battles of ever more contrived euphemisms. George Carlin has a brilliant sketch on this very issue [1], which is both thoughtful and inoffensive (specifically references "handicapped" around the 5:30 mark).

I wonder: does Ticketmaster not make any profit at all on the ticket sale itself (does all that go to the act), and is the "convenience fee" actually their profit? Or is there profit built into the ticket price itself, and the convenience fee just additional profit?

If it's the former, it's still lousy because they're advertising lower prices than what the actual cost is.

But even so, it's still not much different from retail stores charging sales tax. Personally, I think it should be illegal to charge sales tax after-the-fact. The price advertised should be the price you pay, period. In Europe, this is exactly how it is: whatever price you see advertised is what you pay, and that's all. There's taxes (15% VAT I think, so not trivial), but they're built into the price, and they're not allowed to advertise the pre-tax price. This is exactly how it should be.
Why is it not tyranny if I go dump a load of toxic waste in your backyard, just because I can because I'm more powerful.

That is a particularly apt analogy for climate change, because as richer countries belch CO2 into a shared resource (the atmosphere), smaller, poorer countries pay the price with the literal destruction of their entire country (see Kiribati).
> There is no definite scale for the fines though, i'm pretty sure negotiating with the hackers will be cheaper 100% of the time

> If Erlang can handle, say, tens of thousands of TCP connections with one Erlang thread/actor per connection, then only because it is using an implementation of asynchronous IO in the background.

Yes, it can. That's one of the BEAM's key strengths (the Erlang VM). It presents a simple, uniform concurrency abstraction - the process - to developers. Note these are application-level processes, not OS level. They're very lightweight and it's possible to spin up tens of thousands on a single machine. The VM multiplexes user processes over the underlying hardware (threads/cores). More here [0].

AT&T Is Enabling Its Robocall Blocking Tech by Default
motherboard features such as x16 or 2x8 are achieved with "pcie mux" chips. these are devices which select which of N pairs of differential wires is attached to the input/output differential pair. search for "pcie mux" will find many, such as [0]. if you look at the diagram you'll see that it connects wire pair A+/A- to either B+/B- or C+/C- based on the value of the SEL line.

these generally basic passive devices operating at analog signals level, no higher layer activity required. however some may exist which operate as "retimers", which do participate in the lowest layer of the PCIe electrical protocols (generally to extend reach). these are unlikely to be used for a typical x16 <-> 2x8 sort of motherboard feature though.

the example i picked here is 4 lanes, and you would need 4 such chips to do a x16 <-> 2x8. (spoiler: you mux lanes 8-15 from slot X to lanes 0-7 of slot Y, and there are both TX and RX pairs which need muxing.)

there do exist devices called "pcie switches" which operate at all layers of the pcie protocols, and allow for all sorts of sharing of the point-to-point links. examples at microsemi [1] ... for example a 48 lane switch could be used to connect two 16 lane GPUs to a 16 lane slot. this would allow either of the GPUs to burst to the full 16 lanes, or on average if both GPUs are communicating with the host then they would see 8 lanes of bandwidth. there's a picture of such a dual GPU card in this article [2], you can see the PCIe switch ASIC centered in between the two GPUs, above and to the right of the edge connector.
