This is a one-dimensional take. All antennas receive both the electric and magnetic field. You can think of a magnetic field as being equivalent to current in a transmission line, and the electric field being equivalent to voltage in a transmission line. Each antenna has a quantity called wave impedance that tells you what the ratio of electric and magnetic current it couples from and to (reciprocity) free air EM propagation (free air has a certain radiation resistance, and the antenna has its own radiation resistance).

A dipole antenna has high-ish wave impedance, a loop antenna or magnetic antenna has a low wave impedance. It isn't the only factor to whether it is efficient or not efficient.

The actual reason why transmitter antennas have to be pretty good at being efficient--receive performance is much much greater than transmit performance. Receive performance is basically limited by only the noise that comes from its various components. Transmit performance is limited, essentially, by how much power it can pull from the wall and how much power the final transmit stage can take before catching on fire. Every little bit counts for the transmit side, because increasing the power by two costs $$$$$$ whereas decreasing the receive noise floor by half isn't that big of a deal, and half the time isn't even necessary because of atmospheric noise.

The purpose is to lock in automaker supply chain conversions (which takes years to transition). Legacy automakers have proven you can’t rely on them to move to EVs unless they’re dragged there by public policy and an industry innovator. Tesla (and GM/VW to a lesser extent) showed EVs were able to replace combustion vehicles with very little compromise, bolstering these policy moves.

Stellantis would make combustion vehicles for as long as they could, for example.

You won’t believe they’re a reality until AVs are perfect?

Technology doesn’t arrive perfectly in its final form. Progress for AVs is going to look painfully iterative from here. Waymo and others will roll out their AVs to increasingly more difficult areas while also reducing the number of disengagements. They will all likely have a human operator fallback for quite some time.

I chose my words carefully - better, not sole, determinant. But I notice you did not give an example of the opposite: a unified ethnic group composed of genetically distant sub-groups.

Such a group may well exist, but is the exception rather than the rule.
>This is a belief, not a fact. Delusion is where you use mental gymnastics to represent your beliefs as facts. Humans don't fit into frameworks...

If you believe biology, and physics, etc. are not factual frameworks (which they are), then I am afraid there isn't much of a discourse or discussion here. Since we can't seem to agree on fundamental concepts.

>Biology says nothing of how we as humans identify ourselves

Agreed. And male and female are biological terms, that have absolutely nothing to do with how anyone identifies or feels.

> it says nothing of sexuality.

Incorrect, biology explains a lot about sex, namely how reproduction fundamentally works.

> Xy and xx chromosomes don't represent sex either.

Of course they do, that is the literal definition of male and female.

>Your framework is not based on reality, and you nor anyone else can claim they have a framework on human biology or psychology.

Unfortunately your framework is the one not based in reality. You are operating under a crazy assumption that biology is so complex that no one could possibly understand it, and we have so much more to learn! What you are actually doing is rejecting what science has known for 100's of years, and projecting yourself as some profound "deep" person who is able to see beyond what science has already settled.

>We have more questions than answers.

Agreed, there are so many unknown things in the universe, and things to discover, which is why its ridiculous to waste time disputing basic biology 101 things like "What is a male, and what is female" when this has been answered for 100's of years.

If the ROI was in 8 months, I’d think the seller of the tech would be charging too little. Why give it away for that price, when an ROI of 24 months would still be compelling, would give far greater margins and a more balanced split between the consumer and producer of the tech?
Maybe I'm missing something, but the prices look bad for what is offered. Why would you use them over say a managed server, for example from Hetzner [0] or Netcup [1]?

They would chuckle when they realized how instead of seeking to replace $8/hr labor to do simple tasks with fancy robots, we instead decided to focus on telecommunications and mobile computing, and now anyone can buy a smartphone for $800 that has a 120 fps HD+ screen (inconceivable to someone in the 60's) that can download 100mbps (inconceivable) almost anywhere in the world (inconceivable), record 4k/60FPS HDR video(inconceivable), store 1TB data (inconceivable) buy anything in the world and have it delivered tomorrow (inconceivable). We've built far more interesting and useful things.

Furthermore, It's not that we can't, we just don't want to. We like interacting with the world around us. Most people enjoy cooking, cleaning our living spaces, etc. As it ties us to the world. If we outsourced this to robots, we would maybe save some time, but then have to deal with robot repairs and troubleshooting.

But in that case we accept the device as "broken" and need to replace or repair it. If you are lucky the PCB trace was only relevant to a single feature, say an LED. If you are unlucky, it's part of the memory bus and everything is toast. But no significant engineering went into making one more resilient than the other.

Whereas in a distributed system, a single broken communication line, even or especially if it's extremely important, still means that the distributed system has to recover somehow, preferably gracefully.
> libertarian orthodoxy got us into this mess.

What? What@@!@

Hardly, people not listening to the warning of libertarians got us into this mess.

Libertarians have been very accurate to the consequences of government largess, and at every turn people ignore the results of government programs doubling down claiming that not enough money was spent, or not enough power was ceased, or a loop hole was really the problem

No libertarianism did not cause this mess, far far far from it
Any opinions from the crypto crowd? Cash seems like the ultimate libertarian way to go. My cash is physically in my wallet - nobody can touch it or take it. It is indisputably mine. And I know shops, vendors, and pubs will accept it. As soon as I de-materialize the cash into some electronic form, then I become dependent on (1) my phone provider (2) my computer (3) whatever coin exchange is involved (4) whatever method the merchant uses to convert electronic units into national currency so that they can pay their taxes (and probably their suppliers and employees). There are plenty of 100% cash business out there - I think because they like the same liberties which crypto offers...

My understanding of it is the good/service you receive is considered income at the fair market value, regardless of what you traded for it.

> When I worked at a place that did 100% pair programming with rotation every day

Putting aside whether or not it actually makes you more productive, that sounds awful to me. Part of the reason I work from home is so that I don't have to constantly interact with my peers, and can put my head down and concentrate on my work without having my train of thought constantly broken. I have no problem with pair programming as needed, but I would never work at a company that forced it all day. To each their own, though.

American is absolutely an ethnic group. It’s not high salience in the US but it’s very obvious if you go abroad. Black Americans hang out with White Americans, not Africans.

If you’re in a place where there are relatively few English speakers they all hang out together and the first split will be North Americans versus British + Irish + Aussies + Kiwis + South Africans.

You clearly do care. Otherwise you wouldn't have been so actively involved in the comments here.

Your argumentative, dismissive, downright rude attitude does more harm than good. Perhaps take a step back and think on things for a while before returning to discussions like this.
Nope, I have seen tons of times where standards are very disappointing. Even USB-C, which I love, has tons of annoyances if you look at it on it's own.

Most wireless protocols have something in them that kind of sucks. WiFi at one point didn't even have active TX power control.

The value of best practices isn't that they're actually "best", just that they're standard.

We are slowly getting to a point where there are some standards that are crap, like Container Mania that has taken over everything, and putting a blockchain in stuff just because, or the inexplicable use of real databases where SQLite would be entirely appropriate.

But a lot of pretty good stuff gets done just by sticking with best practices. Like, no, it's not ideal to have an 80MB app to flash SD cards.

But it works. It's on all common platforms. And it's fairly safe. And it has notifications, important on a tight schedule.

I can recommend it to anyone knowing they probably won't wipe their disk. That 80MB Electron app may be ridiculous, but it makes flashing solved.

Or Git. There are other version control systems. Maybe better ones. But currently, almost all programmers need to know the basics of Git anyway, and for simple projects there are GUI tools.

Anything else has to be weighed against the fact that git is already everywhere and nobody has to learn a second system, and the fact that Github and GitLab exist.

Or my favorite, JS. As a language, it's a bit crappy, at least compared to Python. But it's in the browser. TypeScript makes it safer. It's got great performance with a JIT and standardized access to lots of stuff, and we have reactive HTML and NPM project management. And it doesn't seem to be going anywhere.

All the extra stuff makes the dev experience sometimes pretty amazing despite the language itself being mediocre.

> "legal tender" doctrine

Yeah, erm. I think you might need to revise your understanding.

Three things for you to contemplate:

1) Credit/debit cards are not "legal tender", a card transaction is not an exchange of "legal tender" and yet it is a perfectly valid means of payment.

2) "legal tender" relates to payments on or to the order of the government (i.e. taxes, fines etc.). The government is the only entity that is required to accept your cash as tender to pay the debt. Private businesses and private individuals can decide of their own free will as to whether or not they wish to accept cash.

3) The *ONLY* time "legal tender" applies to private transactions is if someone sues you for non-payment and you pay *INTO COURT* the value of the debt in cash (the "INTO COURT" bit being the important bit, i.e. it brings us back to (2) you are paying on the order of the court, a public-sector body, which is required to accept "legal tender").
I'm skeptical as well because everyone is saying they've reproduced it, but there's no CVE and none of them want to post the source code to reproduce it. It's all "use this closed source docker image" or "it was in this now deleted github" or "it was in this now deleted twitter leak".
Well, the subject of this topic is the original Facebook itself, not its other properties like Instagram.

That said, if I'm not mistaken I think Instagram too is deemed to be something for "old" folks by the current set of teens, tweens, and younger twentysomethings.
Mathematicians die but their papers lives on. Newton discovered variational calculus, but at the time nobody else in the world understood his work so it was forgotten for a century when he died.

What's your point?

One issue with doing this is that blocking gambling is usually done by the merchant classification. Betting shops are easy to categorise and identify from their merchant category.

Alcohol can be bought from a supermarket, or corner shop, or off-licence. Other than dedicated off-licences, the merchant classification wouldn't be enough to let you block gambling transactions.

To do this effectively, you'd need support in the EMV spec to allow the card to tell the terminal it is unable to pay for goods in a given "category", and have a standardized list of goods categories, and let the POS system send a list of categories to the card before it tries to authorize the transaction.

Otherwise I don't see how you could "delve into" the purchase deeper than seeing it's in a supermarket, and not knowing if it's for alcohol or other items.
I seem to recall doing the math on this one and finding that Netherlands’ own vehicle fleet burns the equivalent fuel that this DC would use in a year, every day. It’s a 160MW (peak) data center and Netherlands burns 180000 barrels of oil per day.

This large American company is simply giving the Dutch something on which to focus their own abundant hypocrisy.
Hi all, I work at JHU apl in the r&d department and wanted to say that we're hiring right now!

Pay isn't FAANG level but you get to do some really interesting work and you have a good bit of freedom in choosing what projects you get to work on. If you're a curious person that likes to constantly keep learning to tackle new challenges, it's a great place to work.

That being said, our hiring process is ancient and takes a good bit of time to go through and you'll probably need to be able to get a clearance of some sort.
You missed my point

"math.isClose()" is making easy things easy. Not easier, a little bit harder, and it is hiding what is actually happening. Like the C++ nonsense I mentioned that did all that (and I was a sinner in those days)

"math.sin(..)" makes a hard thing easy, which is a good thing.

Do you see what I mean? math.colse()" increases the cognitive load for no benefit.

re: 1. With cash, the worst case is that you spend all your money. With a CC, the worst case is that you spend all your money AND max out your CC limit. So instead of having a net worth of $0 (until your next paycheck), you have a net worth of -$10,000. Then every month your debt grows by $200 due to interest.

I'll add another: you tend to miss out on some of the inner workings of the system when you have someone there to answer questions instead of diving in and figuring it out yourself. Yes, in an ideal world you have both, but doing lots of pair programming makes it too easy to take the shortcut and just ask how to do something, instead of learning the fine details of the system such that you don't have to ask those questions anymore in the future.

Heavily agree. So many times rewriting a feature from scratch is faster than figuring out from code, and there is a lot of really hard to understand code out there.

I remember once in a consultancy job for a bank having to maintain a form with a file uploader made of dozens and dozens redux actions interwhining in the most complex way one could imagine. There were atleast 4 folders of sagas.

No one could understand the code, I fought it a few days before deciding to manually document its cases by trying all input combinations I could think of and just rewrote it fromscratch in less than 250 locs. Took me an afternoon to rewrite it and do the maintenance task.

If I had e2es since the beginning I could've figured it out sooner..

Isn't Instagram suffering from the same problem, just lagging?

Teens, tweens, and younger twentysomethings already seem to regard Instagram as something for "old" people.

My main social circle heavily uses Instagram, but its composed of late-20s to early-40s people, which does seem to be the prime Instagram demographic right now.

Instagram kinda feels like the original Facebook as it was back in the late 2000s to early 2010s.
