> . Critically, the eviction ban over the past 18 months has absolutely killed many small time landlords. Any prospective small-time landlord would certainly think twice about getting into the business now, and many existing small-time landlords are doing everything they can get out. It doesn't help that landlords are basically demonized by a large section of the political class.

The end result does not have to be what you mention. We can enact policy to ensure that housing is available to the masses. I don't personally spill many tears over the landlords who lost money. For years, every time people have asked "why can the landlords extract rent", they respond with "the landlords take on the risk". Okay. So this is the risk coming back around. There was never a guarantee that landlords would always make money, nor should there have been.
It’ll be interesting to see how this ages in the next few weeks. I hope you get the current outbreak under control (I have many friends in NZ) but containing the delta variant seems unlikely and because of NZ’s great success so far you seem to have slept on the vaccine. If it doesn’t get brought under control it could be disastrous.

That comparison of life hours isn't valid though. There are additional effect that are wrought on a nation when it's experiencing mass death - mass grief and loss has effects. And that's not to mention the potential overwhelming of the healthcare system, resulting in many other lives being lost or severely impacted.

The meat about the new technology starts at about 4:30 into the video, after some background on the history of A/C and how it works.

> Most modern compressors and pumps use rotary motors to shove a fluid from A to B inside a chamber, but rotary motors can lose as much as 30 percent of their output when they're asked to convert their rotary motion into linear motion required by compressors and pumps. That conversion is done by a crankshaft and once a crankshaft is in the system you get some friction losses but more importantly you get diminished efficiency because you're only getting maximum shove force in the middle of the piston stroke. The start and end of the stroke are both dead points where zero force is available to do any useful work. In a compression task you really want the maximum force to be applied at the end of the stroke not the minimum force. Overcoming these inertia forces every time the motor starts up requires a big spike in power demand which can be as much as five times the motor's normal operating consumption.

> The technology that Magtor have been quietly developing for over a decade now is a magnetically driven linear motor that completely eliminates the need for a crankshaft and achieves far higher operating efficiency as a result. Here's how it works. A fixed electromagnet stator sits at the centre of the motor. On either side of that are magnetic plates that are connected to each other via a shaft that runs through the middle of the stator. That connection effectively turns the two magnetic plates into a single moving part. As a voltage is applied across the electromagnet its polarity attracts the magnetic plate at one end and repels the magnetic plate at the other end. But because it's an electromagnet its polarity is changing 50 or 60 times a second as a result of the alternating current flowing through the copper windings. [...]

> You also avoid that costly power spike at start up as well. Because there's negligible mechanical inertia to overcome, as soon as an electrical current is applied the movement caused by magnetic attraction and repulsion can get going instantaneously. And on top of all that, Magtor have developed a very smart additional element that optimizes the motive power provided by the magnetic flux of the system. [...] In this working example a magtopressor is connected to a five-litre tank of air. Magtor's tests have shown that their device, which is smaller and lighter than a traditional reciprocating piston air compressor, can pressurize a cylinder 38% faster while consuming 33% percent less electricity.

And offered this as a solution:

>We desperately need some kind of government intervention against this in the US. I'm convinced that single payer would fix this in a fucking jiffy.

The fact that the US government is already intervening in over half of all healthcare spending, and for at least 45% of people, seems to be a relevant counterpoint that this problem is not caused due to a lack of government intervention and the way insurers negotiate with healthcare providers.
> Usually too it is some former soviet person.

Sure, what would a former Soviet scientist have to inform us about about the dangers of politics interfering in the scientific process. Not like they have a history of jailing scientists who don't tow the party line, of bright scientists defecting to enemies to escape oppression, of politics dictating what academic conclusions are and are not permitted.

> Science is inherently a political process, and this author seems to lack the self awareness of how her own bias has influenced her.

Or maybe that bias yields some useful historical lessons worth learning from, rather than simply dismissing it as "bias".
I keep seeing apps like these, and what they almost never have is sharing notes between multiple people.

I use Apple Notes, and I constantly share notes with my wife — and entire folder structures, too. We use it for grocery lists, dinner planning, travel planning, and many other things. It's not quite as elegantly real-time as Google Docs, but we don't need that as much, since we tend to edit at different times.

I also like that Notes is rich text all the way. My heart sinks when a new note-taking app boasts of Markdown support, as if that's a good thing. I think Markdown is fine for technical docs, where no good standard for rich text editing exists. But Markdown is a compromise — things like asterisks and underlines are less legible than the bold and italics they represent (especially across more than one word), and links become nigh unreadable, not to mention things like inline images and tables.

I previously used Evernote, and I've tried Notion (slow, awful for organizing, "block model" gets in the way of writing). I've yet to find anything that matches Apple Notes.
> Using someone's preferred pronouns is not "ideological control".

It's very cunning, because it forces people to adopt a certain thought framework... against their will, it's not just about being polite. It has subtle ramifications, the people who architect these ideology are fully aware of.

The whole preferred pronoun thing is akin to religion in my book and purely ideologically driven.

10 years ago it was: "why do you use my preferred pronouns?
It costs you nothing". Today it is "Use my preferred pronouns or you're a bigot and group X or Z will shun you".

You can beat physics. Big cars means more energy to dissipate in a crash. If the regulators had half a brain they would of taxed cars based on volume + mass. Large cars also reduce visibility which further reduces safety. There has been a car size arms race for the past 30-40 years. Cars are getting bigger so you get an even bigger one to feel safe and have enough seat height to see around you.

Great points. Out of curiosity, what are some examples of modern architectures that don’t use IEEE 754 floats? Realistically, how often would one ever write code that needs to be portable between an architecture that uses IEEE 754 and one that doesn’t? I could only imagine this ever being an issue for code that needs to be deployed to a wide variety of exotic embedded systems, which is an extremely niche case IMO.

I don’t think American government is special compared to a lot of other places that provide more services. Often we have less corruption. What we do have is a lot of corporate de facto control of government IE the pharmaceutical industry - this comes out of a desire to have minimal government.

The American healthcare system is not better because we spend more money, it’s better because we have good universities and lots of immigrants.

Agree we should lower costs - deregulation does not lower costs in this case.

> JSON’s design assumes the user can read the entire file into memory

No? The design of most JSON libraries assumes that, but there are perfectly good incremental JSON parsers out there[1–3]. It’s just that people don’t seem to have figured out a good API for not-completely-incremental parsing (please prove me wrong here!), but this applies equally to any structured data format as soon as you want to pull out pieces of data that are nested more than one level down.

The lack of length prefixes in JSON does indeed make a solid parser somewhat more difficult, but you get the ability to author and validate it manually instead. All in all a draw and not because of the incremental parsing thing.

(Tabular or otherwise homogeneous data is indeed reprsented wastefully, but unless the individual records are huge json+gzip is a perfectly serviceable “worse-is-better” solution, and its self-describing nature along with support for structured cell values can at times make for a better experience than TSV. And at other times not.)

It is strongly implied in figure1, figure 3, and explictly expressed ("You don’t need a PhD to see why trucks and SUVs are more likely to kill people walking: They’re taller, have worse visibility, and are more likely to produce head/neck injuries than leg injuries."). The cited reference did not directly support the visibility argumentt or the specific injury types (although I do not doubt that they could be true).
I suspect the reason is that in many western nations, it's becoming politically incorrect to paint socialism/communism in a negative light, despite the realities of the 20th century (and present atrocities being committed by the current mainland Chinese government).

Two strokes (and any other small engined scoot) qualify as low speed motorcycles here in Ontario. They require license, registration, and insurance. As a result, there is no market for them.

Ebikes on the other hand are legally bicycles. As long as you have pedals and officially limit yourself to 500W/32km/h, there are no restrictions.

At these low speeds, even a "small" 1kWh battery can run for two hours. That's 60-70km of range. Good for most commutes inside the city. Any further and you can take it with you on public transit that supports bicycles.

Really hard to make a case for two strokes here, maybe you live somewhere more forgiving.
Yes, it can be pretty trivially falsified. https://github.com/osqzss/gps-sdr-sim

I think GP meant more taxes to cover for country infrastructure (roads, power, etc) , schools, universities, health insurance, pensions, ie the 'all inclusive for everyone' package which is more common in Europe than in the US.

Some of these taxes are paid for by employers.
Edit:and they cover costs for everyone, including non employees (they're generic taxes, not employer-funded health insurance). So you have 'not the whole population' funding the whole population.

Basically, it's more expensive for the company to hire you, so you get less.

I remember talking to a company which could hire me either in the US or in the EU. US paid better because cost of employment was lower, but at the expense of an overall less complete package for me and my family which I would have had to complete with my own money .

In the end, you can't really compare raw salaries - you need to look at what's included, and what kind of cost of living you will incur.
Then TSMC's intellectual property becomes public property. An effort immediately begins to clone anything relevant.

Apple, Samsung, Intel, AMD, Texas Instruments, Nvidia, ASML, IBM, and so on. All are now welcome to take TSMC's intellectual property and use it in any way they see fit.

It'll be a spectacular race, and those companies have the resources to pursue it properly.

The same goes for all intellectual property in Taiwan. It all immediately becomes public property, free for anyone to utilize.

Who says? The US Government does, and the Europeans will likely agree. It'll usher in an epic confrontation politically and economically with China. The world will - practically overnight - split into two major factions, as with the Cold War.

Any people inside TSMC that are able to escape, or that are already in the US/Europe/etc, go to work helping the US and its allies to clone TSMC's technology. That includes spending the required sums to build fabs to accomodate that outcome. It'll be relatively easy for TSMC insiders to dump all relevant company trade secrets over to the US and its allies, which would be guaranteed to occur.

Honestly, the first couple weeks of ownership are like that. Then you realize you can't possibly use 400 km range doing daily tasks and you don't even glance at the range anymore. Plugging in becomes part of the routine like closing the garage.

Even road trips are low stress in EVs with good range. The car navigation adds stops and you can just blindly follow. I manage the stops more actively, but I find it fun (I also optimized furl economy in my gas cars too, so same thinking really). You could easily do a 1000 km day without thinking about range once, just follow the directions.

>especially since your cost breakdown was in response to a comment about how government intervention is needed to bring down costs. I was trying to explain how that doesn't mean government as a single payer would necessarily be more expensive. I'm glad that's not what you were trying to say.

The link I shared was to show that the government is already intervening in the market by paying for over half of all healthcare and paying at least 45% of people.

>And the government compensates them for the additional costs this incurs, yes? I will admit that the ACA has muddied the waters of this conversation.

Technically, yes, but not directly. All other insurance subscribers compensate for the additional costs from increased premiums. But the government does provide subsidies to lower income people to pay for those premiums. But without the subsidies and the lower income people purchasing the insurance, the system would still result in the other insurance subscribers paying higher premiums to subsidize the costlier insurance subscribers, just like in any other insurance pool.

>I think we disagree on which one, but now I'm not sure because apparently we disagree on what's even relevant to the discussion. Maybe let's take a step back. What is the takeaway you want people to have after reading the cost breakdown you shared?

That the government is already heavily involved in price negotiations for healthcare in the US. Therefore the problem cannot be due to private insurers. I point out in another comment in this thread that I think this is all due to politics, and being able to disguise who is getting what portion of the limited supply of healthcare there is relative to the demand. The lack of political support for broad access to healthcare for everyone, and the incentive for certain tribes to ensure their fellow tribe members are prioritized in receiving a greater than equal allocation of the available healthcare is what would have to be addressed (which is a very hairy problem, and is going to veer into classism, ageism, and racism).
