Yeah -- nothing mysterious is happening, the electrons coming out of the battery are just causing an electric field, which causes current in the wire near the 'lightbulb.' This electric field obeys the c speed limit, so if the battery terminals were far away from the 'lightbulb,' there'd be a fundamental physics limitation, the current couldn't start until at least d/c (where d is the distance).

More likely the electric field would be too weak to measure, but that's not fundamental -- you would just have trouble finding a sensitive enough 'lightbulb.'

Nice abuse of Popper’s phrase.

Of course you have just hoisted yourself on your own petard: it’s hard to dispute that American capitalism cannot tolerate competing ideologies, evidenced by (e.g.) The Vietnam War and Korean War. But now I am just repeating my original comment.

You also have another glaring problem to address: it is very easy and simple to tolerate the kind of socialism/communism where an independent nation state wants to use it’s own national resources instead of opening it up to foreign private interests. No one is harmed by that.[1] I guess the CIA just had a very eccentric interpretation of Popper.

One definition of "worked" is "When you say Silicon {whatever}, people outside of {location of whatever} know where you're talking about."

Another definition is "Famous for producing notable companies."
1) He was on another team the first 6-7 months of that. He was transferred to me on account of previous project being wrong area for him (it required domain knowledge he didn't have and didn't pick up). His former manager had worked with him before, so we gave him benefit of the doubt. After a few weeks of ramp-up on my team, he started giving me productive progress updates throughout every week. "I spent all week debugging such-and-such. I spent half the week helping Joe debug a problem", etc. He was very nice and external signs were fine. Then I saw his actual code was minimal, and sadly I learned that the engineers he kept telling me he was busy helping (which would be super valuable work) weren't actually getting that help -- he'd occasionally answer a question, or spend 15 minutes looking over someone's shoulder.

2) A guy on my team is repeatedly telling me he's on the verge of solving a tough problem, and then I take a look at his code and discover it was a trivial issue all along. No, the answer was not that I should have jumped in earlier and taken over the bug myself.

His story ended by being put on a performance plan, which he failed, and then we let him go. At the end of the day, though, he could very likely have stayed with us, if he just accepted my feedback that his productivity was far lower where it should be, and lower than all his peers. He refused to hear it. "You can't measure my performance based on LOC!" Correct, but the LOC was the first clue that he was delivering nearly zero value.

The reason I even told this story to begin with was because some developers somehow tell themselves that they're super productive despite barely checking in any code. By and large, that can't be true.
That's my take on it. You know, if the researcher hadn't invited a fake person to lie about his identity, I would've been happy to participate. I'm cranky about the deception that made me lose sleep over a research project.
I've been partially following the discussions around the original Veritasium video and all that it's caused, and my thought was basically the same: the masses are just rediscovering what was known over a century and a half ago and that theory has found countless applications in communications and power distribution for roughly as long. IMHO that's not a bad thing, but to present it as something novel is.
My early thought was that, at the very least, Poynting Vectors deserve a video but Transmission Lines also deserve a video.

Here's a problem I recall from Jackson which might (or might not) provide a missing link:

Given two parallel conductors of arbitrary shape, prove that the product of capacitance-per-unit-length and inductance-per-unit-length is a constant (i.e., independent of profile and separation).

I remember finding a suitable answer, but I can't for the life of me remember how.

> baseload supplier

the cost of 1GW nuclear these days is starting at $6B. For that amount of money you can double/triple diversify between solar and wind, so you'll always have that 1GW baseload and with much lesser hassle and damage than nuclear.

>its renewable energy neighbours

And nuclear is bad investment from that POV too - 10-20 years down the road after building reliable renewable energy system Germany for example will ask itself "Why we're still supporting the nuclear next door?" France isn't Lithuania of course and will be much harder to force to shut down nuclear, yet i think that neighbors pressure is coming.
It sounds like they are trying to have it both ways. On one hand, they need to do something. On the other hand, they can say, well we couldn’t identify the perpetrators, so oops, we tried.

I've worked on a lot of legacy Rails apps. Most of the problems of "spaghetti code" occur because people write bucketloads of un-Ruby-like code that betrays a serious lack of understanding around how Rails really works. Whenever I hear "aw man, Rails sucks. I switched to writing (X) in Rust/Go/Haskell/TypeScript/whatever…"

Let me stop you right there. If you tell me Rails wasn't meeting your needs so you rewrote (X) in a different manner using Ruby + something else, I'd totally understand. Otherwise, all it tells me is that there was a tragic lack of deep Ruby knowledge, respect even, to begin with as the project unfolded. Often I muse on how in some ways it was unfortunate that Rails became such a darling in the startup community early on. It meant that a ton of people jumped into Rails web dev thinking they were writing "Rails". No, you're writing Ruby, and Rails just provides a nice set of base classes and some decent defaults and assumptions. If you end up with a giant wad of spaghetti mess, that's on you. It's totally feasible not to end up there, and plenty of projects end up in far better shape.
This is true for a lot of people in tech, in general. Part of it is because tech people are, on average, much smarter and much more curious than an average person. Now, you take a smart, curious person and you make them work at a computer connected to the internet -- the largest knowledge base ever created. That's like hiring an alcoholic to work at a liqueur store and expecting them not to drink during the work day.
By that same logic, a person with an oil truck is more dangerous. Yet, we trust these people to drive these things in broad daylight?
I think that was the implication -- that experts are often wrong. One could go the No True Scotsman route and say that a true expert would occasionally select randomly following a Bayesian Bandit approach for optimal decision-making.

Technically there is a very small current that flows through the circuit almost right away due to capacitance and inductance properties of the circuit, so Derek was right technically. That current won't be enough to turn on the light bulb. The rest of the current that actually turns on the light bulb takes some time to reach the bulb because the wire is so long and electrons travel with the speed of light along the wire [0].

[0] actually electrons don't move that much, instead electrons pushing against each other on the wire cause a ripple, it is this wave that moves along the wire and turns on the bulb.
There are lots of even older memes that were fully self-referential. For example, if a forum question got in response an ascii-art homage to the goatse shock site, I would also label that as absurdist/wacky subculture self-reference meme, and that predates the lolcat/Scumbag Steve memes by something like 10+ years.

> this means more CO2, bigger dependency on Russia

That's arguable, but certainly not definitive. This is based on the assumption that energy usage will only ever rise (until the final collapse of industrial civilization), generating an ever-increasing abundance of waste (food, electronics and other supplies) and empty buildings (3 million empty dwellings and counting).

Some of us do want to build a lowtech society in which we don't have to choose between killing millions of species due to capitalist activity or living under a rock.

> more expensive electricity in the end

This part though goes against all current studies. When public subsidies for building/deconstructing nuclear plants are taken into account, nuclear is by far the most expensive energy source.

This is of course assuming that they even know how to deconstruct those. It's not like like a site they stopped in 1985 and claimed would be a showcase ("vitrine") of how to dismantle nuclear plants had its plans go 20 times over budget and the estimation kept climbing along the due date currently scheduled for 2040. Or is it in fact just like that?! [0]

If a job fails, the connection to the database will timeout. Postgres will rollback the transaction, which releases row locks, freeing a job to be retried.

Of course, the database client and server together form a distributed system. The client might continue processing a job under the mistaken impression that it still holds the lock. Jobs still need to be idempotent, as with the streaming platforms.

Same. I had a troubled childhood and many D's in high school. If it wasn't for me studying really hard and getting a 2320 on the SAT, I wouldn't have gotten into any school, but that was enough for UCLA to take a chance on me.
Veritasium is the better teacher. The rest is just jumping on the bandwagon to grab viewerships. Think about it, back in your school days, you have an inspirational teacher that challenge or motivate you to pursue something. Rarely that teacher will spoonfed you with all information. I have many great teachers that explain well. But not a single one of them make it to the list of inspirational. I have 1-2 memorable teacher that really inspire me and they don't exactly explain things exceptionally clearly and all-in-one package. Veritasium is the kind of person that moves needles. Electroboom will be the inspired students to follow-up. The fact that he demo that wind car thing correctly and better than the specialist shows that he is the better teacher.

> at least weary of China if not openly hostile

Given the latter half, I think that's *wary (cautious) rather than 'weary' (fatigued, fed up)?

I'm not American, but something I've noticed on YouTube is that 'import' is a euphemism for 'Chinese crap' - probably more prevalent because there's more of a US manufacturing base to begin with, but the funny thing is when it's imported from somewhere else that's respected it's a German tool, or Japanese for example, but 'import' seems to mean 'imported from China', heh.

(I'm not claiming I'm above it nor offended by it, just caught my attention because 'import' isn't an adjective to me and the usage amused me. It wouldn't really catch on in the UK I don't think, because so much is 'import' to begin with, whether Chinese or not.)
My suggestion is try and get feedback earlier.

Whiteboard with your coworkers and architect what you are building once you have a pretty good grasp on how you want to solve a task. You probably have some code at this stage to feel pretty confident that it will work.

Agree on naming of concepts and design at this point, allowing you to change direction without reworking too much. Of course further changes to design will occur as you learn more during implementation. If they are major run them by your team again to keep them in the loop.

It is probably true that you could work faster, at least for a while, if reviews were more slack. That the company chooses to prioritize less risk instead.

Maybe it is just time to move to the next job since your learning curve is flattening?
Great HN post. Thank you for OP for supplying the link.

Through my various social engagements, I've spent time in many political discussions. Trump, politics, race, and anti-vaccination are recurring themes. Some observations:

* Those on the left tend to insert race into situations in which it does not naturally arise as I see it. Here focus is nominally on inclusion/significance of minorities. It periodically comes with a tone of judgement something like getting a visit from an evangelical at your door. Listen to NPR: at least around north east cities it's replete and centered on identity politics.

* Those on the right tend to insert race into situations in which it does not naturally arise as I see it. Sometime emphasis here comes as self-righteous anger, feeling excluded, and kind of self-imposed victimization of thought or culture putatively at the hand know-it-all-liberals.

* Older guys on the right side who are pro-Trump, anti-vax tend be the angry individuals spending time recollecting the good-ol-days when guys were hardcore men. I sometimes probe these older guys with questions. What I tend to get is a lot o whining, frustration but little in the way of answers. That's a shame: us older guys are supposed to have some answers standing on the shoulders of our own experience.

My view then is the emotionalism, complaining, putative self-righteous anger, and whining is a layer on top of a more basic problem which is victimization. And that sits on an even deeper layer of lack of competence broadly speaking on what to do about it.

Whether it's "stop the steal", deep state, MSM (mainstream media) there's a running sense of we're victums. Look at headlines. You'll see plenty of "The real truth behind..." (i.e. you've been lied to elsewhere), "The dirty little secret at..." (i.e. people have omitted information we're strong enough to tell you).

I yet remain convinced that the majority of Americans (of which I am one) know full-well the solutions are at the center. I also feel like almost all Americans are sick-and-tired of the 24-7 soap opera from the talking heads on TV, and headless voices on AM/FM.
Great point! This is exactly why fuite does a preflight iteration before the "real" iterations. One-time setup costs shouldn't count against the "leak" – only sustained memory growth.
In my opinion the video made a couple of mistakes, which I think ElectroBoom's response* addresses nicely.

Also its proof using the pointing vector to show the flow of energy is misleading; In the video Derek shows that the energy flows toward the lamp when the circuit is already in a stable configuration, but the point of the video is to explore what happens before the circuit reaches that configuration.

This is relevant: assume that the right half of the cable is connected to the positive pole of the battery, in a stable configuration every point of the right half of the circuit has a positive charge (creating the poynting vector field as shown in the video) while 1/c seconds after the switch was closed the wire just to the right of the lightbulb will have a negative charge (the cable near it is positively charged from the battery and so the upper cable acts as a the negative half of a capacitor) which changes the direction of the poynting vector.

In the end it felt like it was telling you that its message was that energy travels via the fields but what it actually said what that switches cause electric interference.

Kind of curious where you live because the police seem to only look for drunk drivers these days, for the money.

In Phoenix you have to make the police do their job (like take their bumper off) if they don’t think you’ve been drinking because they know they just have to wait a bit to write up a big-dollar ticket.

Most nuclear incidents do not involve stuff blowing up, but rather stuff leaking. As for covering things up, that's a specialty of this field, as any former nuclear insider will tell you.
