> I fly Southwest, which guarantees no seats, but offers free changes.

I think you mean it doesn’t guarantee specific seats. It still absolutely has to guarantee you a seat on the plane or suffer the same penalty as any other airline for overbooking. They are not exempt from that requirement.

I don't know how popular car sharing is in the US, but it's common in a lot of European cities, and there's literally nothing to renting a car (either short term or multiple days, admittedly, not at great prices for multiple days) than choosing one in an app and driving off. They validate your driver's license when you sign up.

I suspect the reason the counter is there is to upsell people, and that car rental companies make significantly more money because of that bad experience. But god, I would and do pay a premium to not have to deal with that crap.
The challenge is that it’s clear the vast majority are willing to put up with a lot to get a low fare.

And that includes me. I remember flying return from SFO to Barcelona for $500 on a budget international airline (Norwegian Air). No food service, no drink service, but it was a A380 fleet so quite comfortable. Read the fine print and you avoid all excess charges like printing tickets, bagged checkin fees, etc. Cheaper than flying return from SFO to NYC.

For those that aren’t willing to go cheap, there is now Premium Economy which seems to be growing in size as a class. I think Singapore Airlines now run flights that dont have basic economy any more. It’s either premium economy or business.
It probably depends on the company. Most gas pumps in the US only support swipe payments (as opposed to chip based EMV or contactless). The gas station gets charged lower credit card network fees if they submit address info with the swiped payment. Whether the address is correct or not doesn't affect the fees, and it's usually up to the company to decide if they want payments to be declined when there's an address mismatch.

You can often make a reservation without providing billing information, so there's no mechanism to enforce a payment for no-show. If you prepay for the rental it's different, but there may also be a significant discount.

Thank you. I do agree that peer review must be done, but it's almost too simple.

None of the parts of my proposed prototype are very interesting or controversial. I'm not using extreme magnetic fields, or exotic materials or new physics. Nothing about the device requires more than highschool physics and geometry to understand.

With a new arrangement, this novel solution to contain and collide ions falls out.

It's a gedanken that just needs to be built because the basic idea is less involved than some homework I've had.

Here's the main idea in the style of a highschool homework assignment:

Draw a point on a piece of paper. How many unique circles you can draw that pass through that point?

Each of those circles represents the cyclotron trajectory of a single deuterium ion in my device.

There's basically nothing to write about until an experiment is built.

I need some "marketing neutrons" as Michel Laberge of General Fusion put it (https://youtu.be/2m9kC1yRnLQ?t=639).
> I'd be in favor of this change iff capital losses could offset capital gains infinitely forward and backward in time with no limits.

I'm not negotiating with you, I’m describing how to undo a deliberate price distortion advantaging a particular class in status quo tax policy.

That said, while I wouldn't do exactly what you want, I’d do something similar and from the perspective of basically every taxpayer with capital losses (and many without) better:

(1) allow recognizing income for tax purposes is advance of realizing it, without limit, inflation indexing advance-recognized income when it is then used to offset against realized income.

(2) allow capital losses to offset income recognized in the current year (this is effectively the same as an infinite forward offset against income, not restricted to capital income, and protected against erosion by inflation.)

(3) allow deferring tax recognition of any or all realized income exceeding 110% of the minimum realized over the past 3 years (excluding 10/9 of any deferred amount; that is, with maximum deferral amount, the baseline would not change), provided that no amount may be deferred without first using all available advance-recognized income.

(4) Allow further deferring up to 90% of any remaining previously-deferred income after recognizing all current realized income not
eligible for deferral under #3.

(5) At death, final year taxes would allow notionally “deferring” any taxes deferrable under the normal rules one final time, which deferred amount would then be taxed at the average (not marginal) rate of the final tax year before the “deferral”.

(6) At death, any unused advance-recognized income after applying to the final tax year would be retroactively applied to past tax years starting with the most recent (but “deadjusted" for inflation back to the tax year it is applied to.)

(Tangentially to the central issue here, I’d also eliminate separate estate and gift taxes, but keep the per-recipient per-year exemptions from the former for tax free transfers of either kind, and then tax any non-exempt transfers as normal income to the recipient.)
I just rented an 'intermediate car' from Avis in Dallas a few weeks ago. Got a Dodge Challenger R/T. It sounded amazing but was hilariously slow.
The old term for .NET/Java was "Managed" languages. "Managed C++", "C# is a managed language", because they all manage your memory for you.

Rust's primary language feature - the borrow checker - is about adding compile-time checks on resource management(mainly memory), and the original article talks about boxed vs. value types being a major source of inefficiency.

So talking about Rust in a comparison of C and Java mentioning memory indirection bottlenecks seems about the most relevant place to discuss it.
Also availability. The more basic the chip, the easier / faster it is to get 1k of them. (or to find a perfect/close match requiring minimal changes)

No, it's mostly not true because Rust does not prevent logic bugs.

The mRNA COVID-19 vaccines seem to do all of these: they reduce infection; reduce chance of symptoms given infection; and reduces the chance of severe illness given symptoms. It's much less so for Omicron than for past variants.

MMR is similarly effective at infection vs. mumps as the mRNA vaccines are against infection with pre-Omicron SARS-CoV-2.

Transmission is a harder question: if you prevent infection in a bunch of people, but also create more asymptomatic people who are likely to go out and about: which effect wins out?

Yeah it's so weird. Once we had the vaccines the actual dangers vastly dropped but people still cling to their fears. I suppose the media drum desperately beating for clicks/views is not helping much with that.

> So, anecdotally that's your experience

Yes, anecdotally, almost every single educated person I know in the West is remarkably ignorant about China. They don't know even the most basic things, like the names of the major provinces or the names of cities with 15 million people. They couldn't tell you the first thing about Chinese history. When did the empire fall? They couldn't name one major Chinese literary figure in the last 500 years.

I'm talking about people who are fairly international, who might speak a few different European languages. The sheer lack of knowledge is really striking.

I don't think it's the case that the people I know are almost all anomalous in this way. Knowledge of China is simply near zilch in the West.

Young, educated Chinese people practically all speak English to at least a basic level. That already gives them more knowledge about the West than the average educated Westerner has of China.

> forced labor

I'm assuming you're talking about Xinjiang. This is an issue that I am certain your average person in China understands far better than your average New York Times reader. The programs that are being labeled "forced labor" by the US government are fairly well known in China. With a lot of these types of China stories that hit the news from time to time in the West, you'll find that the average taxi driver in China knows more detail than what you'll read in Western newspapers. The idea that Westerners know what's going on in China better than people in China do is just hubris.

What about an emergency credits system? In an emergency, the government issues 100 credits to every person, each equal to $x. Prices for essentials are shifted to credits for the duration of the emergency (but remain floating) and shopkeepers can exchange credits for cash with the government.
In this case it's not relevant, because it couldn't explain these similar magnitude trend lines adding up to something so tremendously different.

The effect is caused by the age data ending in mid-October, before the spike we're looking at in mid-December. So, the age-segregated data couldn't show that spike at all.
> it takes nothing to sign up for the rental company's 'frequent renter' programs and that usually gets you access to a priority counter or line

Yes, I've done that with most of the major rental companies, and I agree it does cut down on wait time considerably. My experience has been that the service itself still varies considerably by location (although I've still found it to be better when traveling on business). The vast majority of my rentals have been at airports and it's very hard to predict which ones will have better service; I've had very bad experiences at large airports where you would think they would have the process down pat, and good experiences at smaller airports.

Inflation has historically been targeted around 2%, though we've seen period of higher inflation and sometimes very rarely a little bit of deflation (though not recently).

Some inflation is normal and fine. 6% is rough but tolerable, but getting it back to 2% is obviously desirable.
Really not the same beasts. The Cortex M4 microcontroller is self-contained with every peripheral it needs (including BT and wireless stack) and its power consumption is very small compared to a SoC.

Also, it's not booting Linux at all. For these simplish one-purpose applications, you don't want the overhead and it probably would need more than the 24k or RAM onboard the nRF52810.

They could be using Zephyr though as it supports the Cortex M4 (it's a linux-like RTOS that can be heavily customised).
Moon orbiters have the difficulty that there "mascons" (mass concentrations) on the moon that make its gravitational field very lumpy. https://en.wikipedia.org/wiki/Mass_concentration_(astronomy)...

That makes an orbital GPS difficult.

> Lunar mascons alter the local gravity above and around them sufficiently that low and uncorrected satellite orbits around the Moon are unstable on a timescale of months or years. The small perturbations in the orbits accumulate and eventually distort the orbit enough that the satellite impacts the surface.

> Because of its mascons, the Moon has only four "frozen orbit" inclination zones where a lunar satellite can stay in a low orbit indefinitely. Lunar subsatellites were released on two of the last three Apollo manned lunar landing missions in 1971 and 1972; the subsatellite PFS-2 released from Apollo 16 was expected to stay in orbit for one and a half years, but lasted only 35 days before crashing into the lunar surface. It was only in 2001 that the mascons were mapped and the frozen orbits were discovered.

> ... At that time, one of NASA's highest priority "tiger team" projects was to explain why the Lunar Orbiter spacecraft being used to test the accuracy of Project Apollo navigation were experiencing errors in predicted position of ten times the mission specification (2 kilometers instead of 200 meters).

On the other hand, these "leaky vaccines" have already prevented a massive amount of mortality. Yes, the duration and quality of protection, even boosted, against Omicron is unfortunate... but even 2 doses can still be expected to save a high number of lives from Omicron.

There is no evidence that the "vaccine only works for a couple of months".

The vaccine has continued to show efficacy against hospitalization and death (severe covid) even as there has been some waning in infection immunity over a period of multiple months (more than 2 or a couple months though). See e.g. https://www.cdc.gov/mmwr/volumes/70/wr/mm7049a2.htm "During February 1–September 30, 2021, mRNA vaccine effectiveness in preventing COVID-19–associated hospitalizations among U.S. veterans ≥120 days after receipt of the second dose was 86% for Moderna and 75% for Pfizer-BioNTech vaccines"

Future covid strains may be more or less deadly - data coming in on Omicron indicates it's more deadly than original COVID but perhaps slightly less deadly than delta. Still quite dangerous to an unvaccinated or immune naive individual.
We don't "know" that. It depends on what data you're looking at. CDC has two papers supporting vaccine-induced immunity, one of which was highly flawed. And then there's the study from Israel clearly supporting natural immunity.

Kubernetes adoption up, serverless down, developer survey says
Most people talking about C# and Java, they refer mostly to application development. You rarely hear these languages at system programming (doable, just rare). Rust is at C/C++ level when it comes to system programming and eliminates a lot of C/C++ issues and yet added features found in Java and C#, and even Haskell. People just don't know a lot about Rust to criticize upon and yet seeing it mentioned everywhere. I can understand if some feel a bit "fed-up" seeing Rust brought up in a non-Rust thread. But I do agree with you, Rust is very relevant for discussion here.

The problem is that different languages do different things at runtime and this is part of the definition of the language. C has almost no runtime, while the JVM is allowed to recompile code at runtime using profiling data it has collected that very run. This is how it can beat C in certain workloads.

What if the runtime for language X (written in Y) rewrites X programs into the same language Z that Y itself compiles to? Yeah, there are up-front costs, so you're still technically correct, but I suspect this isn't something you had in mind.

Anyway, that's what a JIT is.
One problem with this is that when you learn a new technology on your own, you’re likely to use patterns and idioms of the language/tech you know best, and not the appropriate ones that an experienced developer would use. When the prospective employer looks at the code, it will often seem completely naive.

As an example, when I was trying to make the transition from C and Python to C++, I wrote a moderately sized interactive, real time, visual programming language. I didn’t ever show it to anyone, but I went back and looked at it a year later: I totally facepalmed because it was filled with glaring indications that I totally wasn’t a C++ programmer. For example, I often accessed an object’s members with “this->bar” (like in Python, where you use “self.bar”).

I certainly learned a lot, so it wasn’t a waste of time (and it was a fun project for me anyway). If I had a really good friend or mentor who would have been willing to invest the time to do an extensive code review first, then it might have been a useful demo. But at the time, I had no idea just how little I knew!
