Depends greatly on the material used and the cable construction. Typical: 60 strand aluminum (better skin effect properties than copper by the way) around a steel carrier. And yes, those are the largest factors in the boost to DC, but that's mostly because the resistance losses are there regardless so there isn't much else that you could improve on.

If you transmit a lot of power over very long distances then the higher the voltage the lower the current and DC gets rid of the skin losses so there's the case for HVDC transmission lines (which are extremely impressive feats of engineering, as are the substations).

Finally found a good picture of a cross section of a HV AC transmission cable:

https://en.wikipedia.org/wiki/Aluminium-conductor_steel-rein...

Based on that ruler that makes the AL wires about 3 mm each, and the skin depth at 50 Hz would be about 11.5 mm or so, so well within the range where the skin losses are extremely small (they are still there though, and when you're transferring Gigawatts every little bit helps).
According to this map I have nothing to worry about (except for global economic collapse, famine, and war)
Heh, had no idea, they seemed to have a pretty limited run, ran at up 200 MHz, but was pretty quickly replaced by a Pentium-II at 233 Mhz on a single die.
Finally it might be possibe to work from the beach!
It supports operator overloading too, by the way. This makes it usable where many LAPACK wrappers like Numpy are not.
Presumably, the same way they enforce any other supply requirements.
> I propose that that "Nice but not Kind" caricature is actually incredibly rare to the point of non-existence. It tends to be used by the right to describe the entire left - as virtue signaling, caring-about-optics, overly politically-correct, social justice warriors.

Does anyone think that "virtue-signaling, caring-about-optics, overly politically correct, social justice warriers" are being nice? Heck - do they think that they're being nice?

> They're using this exclusively to criticize caring or small incremental progress forward.

You're assuming that everyone views that as "caring" and "progress forward."
"Though, if we are talking about fixing costs, then one thing that'd help tremendously would public access exercise facilities."

I kind of doubt a lack of facility is the blocker. There's nothing stopping people from doing body weight exercises in their home.

"However, intoxicating substances are pretty much impossible to stop"

True, we would only want to restrict it, not stop it. Basically, make the bar for the legal stuff higher enough to persuade people not to use it, but also set it lower than the illegal stuff. Of course it also needs to be accompanied with the lifestyle changes.

Just look at tobacco - legal, heavily taxed, providing minors is heavily punished, large warnings required, even requiring manufacturers to pay for commercials to smear their own product. This could be applied to just about anything.
The purely metaphorical interpretation of alchemy is popular in some circles, but alchemy has a clear experimental basis. Newton did some pretty wild alchemical experiments. Metals are weird.

>Words mean what we do with them -- you need to be here in the world with us, to understand what we mean

This is like saying "humans can't fly because flight requires flapping wings under your own power". Sure, its true given the definition this statement is employing, but so what? Nothing of substance is learned by definition. We certainly are not learning about any fundamental limitations of humans from such a definition. Similarly, defining understanding language as "the association of symbols with things/behaviors in the world" demonstrates nothing of substance about the limits of language models.

But beyond that, its clear to me the definition itself is highly questionable. There are many fields where the vast majority of uses of language do not directly correspond with things or behaviors in the world. Pure math is an obvious example. The understanding of pure math is a purely abstract enterprise, one constituted by relationships between other abstractions, bottoming out at arbitrary placeholders (e.g. the number one is an arbitrary placeholder situated in a larger arithmetical structure). By your definition, a language model without any contact with the world can understand purely abstract systems as well as any human. But this just implies there's something to understanding beyond merely associations of symbols with things/behaviors in the physical world.
These other responses sound like an episode of Dynasty to be honest. All you have to do is keep up a minimum of a mildly positive spin on things and get your work done. That's it.

To get through to management, you'll probably have to kick it up a notch for every promotion.

If there's more drama that than, you're working at a poorly managed organization. Move on at the first opportunity, life is too short.
Not necessarily. There are problems you can't speed up even if you are given a literal infinity of processors - the problems in EXP for example (well, EXP - NP). Even for NP problems, the number of processors you need for a meaningful speed up grows proportionally to the size of the problem (assuming P!=NP).
Ditto. I assumed it was an opportunity to document any legally problematic reasons that drove you to quit so they could get ahead of them, or reinforce their case for firing you.
> What are the qualifications and rules everyone must follow for a "speech" to be free of unequal censorship?

I'd say the first and only rule is that there aren't any rules that everyone must follow. There will be subpockets with different subcultures, with each one building and enforcing their own set of rules, but no single centralized style of enforcement.

No commercial network with a company backing it could ever offer a space like that, because they are liable to monitor and moderate the worst content that goes through their property, thus creating a single centralized culture based on the company's values.
It’s not enough. This has happened a couple of times already, and it’s reasonable to conclude the fake Russian state needs to be split into harmless pieces.
So you’re allowed to choose your job? I thought it wasn’t guaranteed what interests you had vs what you are placed in.

Yea I graduated from Chicago Public Schools and they gave out chromebooks starting in 8th grade. I think that was the first generation of them so maybe CPS get some deal, but through high school the chromebook system only seemed to expand. I imagine it's possible for OP to get one from school.
Why would you use a work-provided chat app to discuss things the company may not like? For example, do you not expect your employer to know if you're browsing for another job over company provided Internet on company provided laptops?

If they were spying on the guest Wifi, that's another thing.
The major thing that is unaddressed is the inertia of the extant built environment.

We know that lead paint is bad for people, especially kids, but we haven’t remediated it in much of the pre-1976 housing stock. Why? It is expensive and the places where it is worst are not high-value areas.

Similarly, there are many homes in America with low voltage knob and tube which is an uninsulated wire. Would you retrofit homes with a second DC circuit or use the existing AC infrastructure and be constrained by the choice of 12/14GA wire? Would new homes have two systems? Would you have a second set of DC distribution wires or a home inverter (with its own inefficiencies and failure modes)?

The supposed efficiency of DC for residential applications will be overwhelmed by the efficiency of doing nothing.
The Curse of Monkey Island was my first contact with the series and I really enjoyed it at that time! I remember vividly the challenge, as a child, of playing it in English while only having the game’s guide on my native language (Portuguese).

Some parts of the translations where totally messed up, making it so hard to understand what I needed to do in the game that I stopped playing it for some years until I could figure out in English what was been said at some parts of the story.

Finishing it was some kind of a personal achievement for me when I was younger.
Obviously you can't have traffic going 60mph in Manhatten but to a point everyone benefits.

Uneven traffic flow results in a lot of lane changing and passing and when drivers are preparing to do those moves they're spending a lot of effort figuring out where the cars are and that creates a prime opportunity for anything motorcycle and smaller to be missed.

So yeah, a uniform 30ish MPH traffic flow on your city street is probably better than a more bimodal one even if the average speed is slightly higher.
> Important to note that tort law apportions responsibility (aka liability) for damages amongst all parties to the tort

This is not consistently the case, but happens to be in pure comparative fault jurisdictions like California.
Over a chat app they provide for work use, I'm not seeing the ethical issue. Pay and overwork is one thing but why can't these employees use their phone for things they don't want the company to observe? Phones are cheap.
> I refuse to do work that harms society, but other than that I'll gladly tell whoever in the office anything they want to hear if "that's how it works".

So does that preclude work where telling your boss what they want to hear puts others at risk? Where along the scale of Chernobyl, Challenger disaster, medical implants, working on Facebook ads, writing enterprise grade Java, or creating eggbeater calibration routines do you draw the line at "harms society" when all you care about is keeping your boss happy?
Well, any changes in sea level and habitability will be a mix of very gradual shift in tidal patterns and acute high-impact flooding events. Areas will not suddenly go from habitable to inhabitable all at once.

In the US, it is very expensive and sometimes impossible to procure insurance for areas at extreme risk of wildfire or flooding. This is essentially the private market's assessment of risk based on location. Most people will leave if they are unable to reasonably insure their homes and property. Cities at very high risk will build seawalls and flood defenses in order to protect their taxpaying base. These are acute solutions to acute impacts.

To preempt some replies, I am not denying the extreme scale of the challenge ahead and the broad impact, especially in less developed and highly dense nations. I believe it is an inevitable adjustment that societies will need to make.
Many laptops can't handle more than USB 2.0 when outputting display over the same port. Those that can need a certain protocol (too lazy to look up). There's a better protocol that allows both, but now you're in the $100+ range of hub/docks that can handle it.
This seems ripe for some Maker to design a reliable alternative as OSHW.

"Having worked in health tech for the past ten years, I can name other companies that are equally massive frauds that just haven't been discovered yet."

You say you can name other companies that have not yet been "discovered" yet, and yet you name zero companies. Are you just teasing. Please name them and let's have a look.
WW3 seems more pressing atm.
Why couldn't HR see this as just a data-point? Put things this way, if the "junior opinionated guy" is full of it, this kind of feedback won't emerge again, and you can discount it.

Or maybe you've got some other data-points indicating this guy is an issue? Say, his projects are consistently late, or there's issues developing new features, or his teams have a higher attrition rate, or, or, or.

This is why it's my opinion that these things should be as secret as possible so people can feel comfortable voicing their real opinions knowing it won't blow back on them, and the company can get real feedback that might prevent thornier issues from becoming terminal.
Presumably because the work chat app is something that every worker has.
I would guess it's the reverse, judging by /r/WorkReform.

It's tens of thousands of people who categorically refuse to understand what employers hire people for, in principle.

Some % of them does understand what a business is, why businesses hire people, and why and how our systems can be realistically reformed to improve conditions for all workers. But most people don't.

I wouldn't be surprised if many of them see the option of posting spicy memes and organizing against one's employer on company time as a fundamental human right.

I can see how, for the jaded, data might match these conclusions.

It feels like something written by someone with relatively low social and emotional intelligence, which will generate a negative feedback loop and more disappointment and cynicism.

You have an opportunity to share constructive feedback. If you use that opportunity to get revenge, it will reflect on you. It doesn't mean you have to lie through your teeth, but it also doesn't mean you owe them the completely unadulterated version of your personal catharsis.

Focus on the outcome you want to create.

> But many (most?) people don't suffer criticism well in my experience - and this seems to be especially true of the people who are most worthy of being criticized.

This is definitely a cultural thing, I brought this up with my team recently, the concept of "negative feedback" and got two different reactions – my feedback to the team was about how we give negative feedback, and nobody at all agreed with that phrasing LOL

Either some people who heard what I said and thought, surely this means when you have done something wrong, and it's not actually negative feedback, but corrective feedback so that you know how to do that thing right in the future.

And the other reaction was, "negative feedback, positive feedback" no such thing it is all just feedback, but watch out for positive feedback because all of it is probably fake, and nobody is fooled by that "compliment sandwich" BS.

I don't think this is a problem for exit interviews, at least not exclusively; the point is that people are either receptive to feedback or they aren't. You can try to candy coat it, but if there's any chance that being direct is going to make the feedback more likely to land, I personally think I prefer the direct approach.

(Then again, I never notice compliment sandwiches, so maybe they work on me.)

What is that?
Why would it be uncoordinated? Volunteers work for FOSS after all, and if the work for IA was also under a FOSS license I don't see why it couldn't work. And IA is high profile enough to attract really talented people from the FOSS community that already understand how to work under that paradigm.

> utilitarianism (ethics come from the outcome) is the better option

Utilitarianism is just as subject to countering every argument for it with "yeah, but why?"

It boils down to the is-ought problem. If you remove the objective will of god, what is left is the subjective will of individual human beings. I struggle to see how utilitarianism would follow from the latter.

> Also Kant positioning himself as a moral philosopher is pretty ironic because he was insanely racist.

Indeed. But look at the time it takes to create new infrastructure (large building, hospitals...) in China when it's needed right now.

I believe we have the technology to make large metropolis in a matter of a few semesters. Even assuming a total lack of improvements, a few years is all it should take to tackle the emergency even if we are barely prepared and organized.

And if there's only one thing to trust, when push come to shove, humanity always accomplish miracles. Crisis unites: people forget about old feuds to care about each other.
Just because a family doesn't want hundreds of acquaintances visiting their home does not imply that their children were unable to see their friends.

I am a software engineer and engineering manager and there's no way I can be productive on a laptop. Even when I have to use a laptop due to requirement by my job, I am using a large monitor as a USB-C dock station, with real keyboard and mouse connected.

Hmm.

I've had nothing but bad experiences with Manjaro's i3 spin (though I do like both Manjaro and Arch, fwiw)

- Manjaro's i3wm lacks a universal theming application like the one Regolith has

- Manjaro's config is not stored as a package manifest

- The out-of-the-box experience is quite poor, it didn't ship with a network manager until quite recently iirc

- The default appearance is quite ugly and barebones

- There is no popup for keybind hints

Honestly, I think their Sway spin is more well-maintained, and that's coming from someone who hates Wayland with a passion unlike anything else.

We have a cut-down but “production shaped” dataset for fast environment creation but even with code reviews it hasn’t been successful at catching the O(n^2) unindexed query or accidental O(scary) at the app tier caused by a refactor. Or the data migration which wasn’t batched but needs to be. Developer turnover is only accelerating, with predictable results.

At this point we are looking into volume snapshots as a potential speedup for creation of a full-sized per-release staging environments but that still leaves the problem of generating a realistic multi-tenant customer load to solve and maintain over time.
What’s a polycule in this context? Apparently it’s a polyamorous relationship group but I don’t see how Tailscale is particularly useful there so it must mean something else.

Starting an illegal war of aggression is a crime for which some people were convicted in Nuremberg Tribunals.

However, all the soldiers fighting in such an illegal war of aggression are not considered responsible for that crime. For "simply" fighting a war and killing uniformed enemy soldiers "I was just following orders" actually is a legitimate excuse, and should not result in any convictions (of e.g. murder) unless they commit some explicit war crimes, e.g. murdering captured civilians.
Interesting how slow USB-C adoption has been so far, which is a shame because the connector and concept are a great standard, but the implementation of various busses (Thunderbolt, PCIExpress), video adapters (Displayport, HDMI 2, 2.1), USB versions (trying to be inclusive of USB 1 through 3 and all its flavors) is maddeningly complex, and unappealing to the typical consumer.
> The unfortunate truth is that humans derive status from belittling others.

It's not a truth any more than 'humans murder others when they're angry'. Sometimes humans belittle others and sometimes they gain status from it. Sometimes they lose status, and I suspect they almost always lose a little self-respect and feel more intensely the shame that was so strong, they just tried to project it onto someone else.

> Being highly educated is apparently no defense against this common weakness.

I think it depends on the fields of study. If you study humanity, you may understand this behavior. If you study quarks, I agree it is little defense.

My experience is that full-stack frameworks like rails (and hopefully redwood) free you from a ton of bike-shedding and customization up front and help you get to a point where you outgrow parts of the framework. An advantage of using something like rails today (or over the past 5 years) is that there was a huge crop of unicorn rails startups that all hit those challenges before and a lot of their solutions are codified in open source tools that can be plugged into the framework. In some cases those startups (like shopify, github) have made huge investments in ruby and rails themselves. I hope in a few years that will be the case for redwood.

I like the concept of innovation budgets for startups. You can only innovate on so many vectors because time is typically your most limited resource. Very few startups have a good reason to spend any of that budget on innovations that are not core to their product differentiation. These things include web frameworks, corporate structure, credit card processing, low-level hosting. Just pick a pretty standard solution that fits your use-case and move on. I don't think it's a coincidence that so many of the big startups over that past 10 years were built with big batteries-included frameworks (would be so curious about a larger study of this, I just have cloudy anecdotes).

Don't get me wrong, I love bleeding edge web stuff and playing with new frameworks. But if my priority is making a new company succeed I'm going to look for a framework that minimizes time spent picking libraries and gluing them together nicely and maximizes time I have to iterate on the product and tweak user-facing business logic.
