> Books are supposed to be source of INFORMATION. A source of WISDOM. They are LONG because they are supposed to express the author’s point if view.

Meh. How many nonfiction books have you read that had 15 pages' worth of valuable insight packed into 250? Often they're too long due to the economics of publishing. The truth is, the perceived value of a 15 page pamphlet isn't the same as a nicely bound book. No one's going to risk publishing just the valuable portion.

I think many people are now circulating those 15 pages as blog posts, TikTok videos, LinkedIn articles, etc. Few make money on books in the trad publishing scheme.

Conversely, I kind of don't mind the lack of attention span in others. In the cases where it's to your advantage to have the attention span to read a book, being able to do so is a powerful competitive advantage. And reading books is one of easiest things to do in this brutal world.
Quite a bit actually. Even highways out of populated areas won’t have any network coverage. Also the same reason satellite radio is still popular and sold here.

I have bookmarked your comment in my Uber-important-but-misc. folder. Thank you so much for sharing, especially the part about how your family’s demonstration of care relates to your daughter and her development.

That previous sentence wariness too clinical, I can’t do it justice, but thank you, seriously. It relates to my experience, and maybe future experience, and I think your perspective will stick with me. Be well.
20 minutes from San Francisco there are dead spots. I go hiking all around the Bay Area, and while it’s gotten much better in the last 10 years, there are so many national, regional, and local parks with huge dead zones.

Most rural areas in the US that aren’t near a town center or major highways are pretty spotty.
I'd suggest reading the Steve Jobs biography by Walter Isaacson. Humans are complex creatures and a distilled one sentence summation rarely does us justice.
My sense is 2-year covers the original owners phone for the average length of time an iphone owner keeps theirs, and for those who purchase phones 2nd hand, they would have to re-up for this coverage.

I would assume when you buy the iphone15 it would come with another 2-years of coverage.
https://mygita.com how about something like a Gita Mini which is a follow bot? It is for paved outdoors as well as indoors. You can lock it from your phone and can follow the elderly person.

I think there are might be some tweaks to make it suit your purpose. But it is worth looking into how it can help senior care as a follow bot.

P.S: I did a ton of research for small farm robotics and met very interesting startup founders in the healthcare/robotics area on the way. If anyone wants to brainstorm or even simply chat about senior healthcare and robotics, please reach out. This is something that is very close to my heart and if I can help make connections even if I can’t help in any technical/material way, it would make me very glad.
Molten lithium would interfere with your magnetic containment. You need a diamagnetic like LiH.

Extracting tritium from a thousand tons of radioactivated lithium hydroxide at PPB concentration is left as an exercise for the ambitious reader.

Good luck.

I think the critical point is: You've done both. I don't know you, but I will go out on a limb and say: having that history as an IC makes you a better EM; one of the good ones I hope.

Great EMs have that experience; and it makes their/your job way harder because now you understand, at a deep enough level, what the people you manage are going through. When product reqs come across the desk of an IC-turned-EM, they can feel that gut punch immediately: "fuck, this is going to be so hard, that system is so legacy, and Sarah is super overloaded right now because she's the only one with any experience on the message bus transformer converter ingester"

Management track EMs actually do have it easier, because they get to think in the discrete world of tickets and human resources.

At a high enough level in any company: senior leadership needs to think about the world as perfectly discrete like that, because there's so much other bullshit going on that worrying about the specifics of the message bus transformer converter ingester would drive them off a cliff. But EMs aren't that. But many, many EMs think like that, and a big part is the incentive structure of their career path; their boss thinks like that, and their boss's boss thinks like that, so if I want to have my boss's boss role one day I need to think like that.

The strawman side of what I'm arguing is: "Well, you're just describing a bad EM". But the whole point is that that's quickly becoming the average in the industry, and that average is starting to define the role. Career-track management who get promotions, then write the hiring reqs for their replacements, and every other EM below them, combined with a massive shortage of engineering talent meaning companies need to define a different bar for their EM hiring reqs anyway.
Oh yeah, I just “converted it” to which iphone had that and mixed them up, thanks for the correction!
I generally just put my XM3s straight into pairing mode and then select them from the device I want to use them on. Otherwise they are bound to pair to the wrong device, usually my sleeping mbp.
I don't really know C, but I think this is a function returning a "struct KaNode*" type, not a struct.
That’s a function that returns a struct. In C structs live in their own namespace and references to them have to use the struct keyword unless you define a typedef.
It's 0.1 seconds now and faster than one can type, as shown by the GIF. What is the speed where it's not rough?
> Performance-wise, kerosene is "good enough". The only area where I see LH2 being worth the effort is military aircraft, especially unmanned.

I'm not so sure. The military tends to put a premium on not exploding, even when fired up on. Even at the expense of efficiency.

Case in point: TNT vs dynamite.

> TNT has never been popular or widespread in civilian earthmoving, as it is considerably more expensive and less powerful by weight than dynamite,[12] as well as being slower to mix and pack into cylindrical boreholes; for its part, dynamite has never been popular in warfare because it degenerates quickly under severe conditions and can be detonated by either fire or a wayward bullet. TNT's primary asset is its remarkable insensitivity and stability: it is waterproof and incapable of detonating without the extreme shock and heat provided by a blasting cap (or a sympathetic detonation); this conveniently also allows it to be melted at 81 °C (178 °F), poured into high explosive shells and allowed to re-solidify with no extra danger or change in the TNT's characteristics.[13] Accordingly, more than 90% of the TNT produced in America was always for the military market, with most filling shells, hand grenades and aerial bombs and the remainder being packaged in brown "bricks" (not red cylinders) for use as demolition charges by combat engineers.

From https://en.wikipedia.org/wiki/Dynamite

See also https://en.wikipedia.org/wiki/Multifuel#Underperformance_iss... and https://en.wikipedia.org/wiki/JP-8 (they add special stuff to make military fuel auto-ignite at a higher temperature than civilian fuel).

However, you might be right that in unmanned situation the military might be ok with more dangerous LH2. Though I doubt it, because the LH2 storage tanks on the ground also need to be relatively close to the front lines. And unless you make it on-site, you need to have a logistics train to get the LH2 there.
Does it have a bimodal distribution because you're combining male and female normal distributions?
By the point we've fused significant portion of Earths hydrogen, it will really not be a problem to hop over to Jupiter for some more. The scales are insane. Energy input of the Sun ALSO isn't renewable if you think like this.
I don't do a lot of C, but isn't this just a global function returning a pointer to a KaNode? If I remember correctly this is just Cs way of specifying a type is a struct same thing with the line in your example "struct KaNode *output = ..." someone feel free to correct me if I am wrong though.

It's hard to really envy anyone who doesn't have a solid relationship with their kids...

No judgement, its impossibly difficult but it just seems like an incredibly painful existence and it feels like that relationship might be the biggest opportunity to have a direct influence on the future most (some) of us get.

Meyers-Briggs is absolute trash and should not be used by companies for anything. Big 5 is also almost completely worthless beyond vaguely describing a person's general tendencies.

>Gmail is awful compared to what? I'd estimate a majority of people disagree here unless you're more of an IMAP purist.

GMail is bloody awful. I can hardly stand using it. Been using Thunderbird for a while now and have not many complaints.

The whole "IMAP" purist thing is unnecessary; there are plenty who prefer not using the GMail interface and have no idea what IMAP is.
My definition for passion is something you need to do, despite having reason not to do it. It's the itch you have to scratch. It comes from the word pati/passio = to suffer.

Passionate people suffer when they don't do the work, so they end up going through the pain of doing it anyway. These people wake up at 5 and do the work, because they just can't do anything else.

I think the trick is finding something you're curious about.

Curiosity comes from being open to different outcomes. When you take something seriously (including finding passion), you're forcing a specific outcome. I'm passionate about cooking. If you give me a steak, I will look for the effect of specific cuts. Can I make a great steak from cheap cuts? Does it taste better with butter and garlic? What can I marinade steak in? Does baking soda make steak more tender? If drier steaks are better, would freeze drying a steak make it better?

Someone who is serious about cooking steaks will only look for the best possible outcome, and probably try to imitate the best recipe and such. There's techniques to arouse curiosity. Meditation has several, but there's also something like Pirsig's Brick.

The other step is commitment. It's tough for a 20 year old. Back then, I did lots of stuff: AI, VR, robotic exoskeletons, solar cars, voice processing, cryptography. Wasn't willing to commit to anything, and somehow got less done than people who committed to something. Until I took a job and was forced to commit to web and mobile development.

Commitment also requires a kind of death of an identity. By committing myself to mobile dev, I'm also committing to not becoming a game developer or an electrical engineer. I get rid of the distractions, and have more headroom to master a certain niche.
Im getting off my SE and getting the newer 14 because of battery life too. Weight and size, the SE was perfect.

You can apply that logic to extol anyone.

So, the fusion we are talking about here is deuterium - tritium fusion as it should be the easiest to achieve. Deuterium is not a problem. A rough estimate says that there's enough of the stuff to cover 100% of the world needs for thousands of years. And it's easy to breed: surround the reactor with water so the hydrogen there can capture the stray neutrons.

Tritium, on the other hand, is a problem. It is radioactive with a half life of ~12 years and so the little we have needs to be produced since we can't really accumulate it. Currently it is produced by conventional nuclear reactors. Additionally, breeding tritium is harder than deuterium and requires a blanket around the reactor that uses other materials to multiply the number of stray neutrons. For each atom of Tritium that is fused we could get somewhere between 1.1 to 1.7 with a theoretical maximum of 2 Tritium atoms so, finally answering your question, it is renewable. It's just hard, but a piece of cake compared to actually maintaining a stable fusion.

I only ever saw one of those being posted to hn quite some time ago. I must admit, that I found this specific example quite disturbing.

The implied undertone was that all others should accommodate the author and change themselves to better interact with the author so that his needs were met and he could be a productive member of the work force.

But what does that imply the other way around? If I were to write a play book like this, were this person to also adapt to my ways/wants? Or would this be too much to ask?

Working in any professional environment to me implies adapting to others around at least a bit (without loosing what makes out our personality). Out of respect to other human beings alone I think this is decent human behavior.

But as said, to me these writings sound like excuses to expect one sided adaption and I could say "pampering". But maybe that is just me.
Best Practice for Database CI/CD with GitHub
Only a limited subset of the available chemical filters are suspected of having an effect on coral. Further, even for those filters that are suspected, I have read that the science is inconclusive.

I personally am skeptical of the idea that sunscreens are actually responsible for marine ecosystem changes, rather than climate change or other large forces. The majority of a chemical sunscreen formula is inert base. And we’re talking about thin films of sunscreen diluting into a vast body of water. Further, most people at the beach are using water resistant sunscreen, further reducing the potential for harm.

Sunscreens are really valuable technology. They prevent skin cancers and sun damage, and I think policy should err on the side of encouraging their use.

I further think that reactive, feel-good measures like banning straws and demonizing sunscreen do much more harm than good, because they cause fatigue and apathy about environmental issues and do little to solve them.

>> You simply can't change something like this, of planetary scale, in a few years, and likely not in even in a few centuries.

As a counterpoint we, as humans, got here in roughly 100 hundred years with the bulk of the damage done most recently.

Although most of that can be cast at "advanced western civilisation" and ideas of capitalism based on unlimited growth etc. Not really something that culturally had much traction with my people, but we are all the shit together.

I'm fairly optimistic that we (locally, here in W.Australia) can hit production of 15 million tonnes / per annum of green hydrogen by 2030 (that's generative from renewable eneragy with no "blue hydrogen" from natural gas).

Small beer against the petawatts required on a global scale but we act locally and ask that others make some kind of effort to match.

You really opened my eyes to some new and important information about how agriculture works.

You’re right, that statistic is misleading. We wouldn’t be using grazing land for anything agricultural if not feeding animals. I definitely won’t use this statistic anymore.

For what it’s worth, I didn’t meant to skew things with that 3% in a disingenuous way. Since I had the number 77 I should have used it though, you’re right.

This has sent me down quite a rabbit hole of understanding agricultural practices, their impacts on the environment, and many other parts of this complex system of how humans sustain themselves.

The information is hard to find, surprisingly. It’s good to get a little closer to the truth, though. Thanks for pointing me in the right direction.

I like to get feedback on something working as soon as possible because I'm likely a bit wrong and I will need to refine or rethink the whole thing again, rust is putting obstacles in my way, Zig is not.
