>Why can’t I go faster than the speed of light?

I assume people know how bad the penalty can be for going merely 10 MPH over the speed limit.

Don't worry about an individual photon except as part of an image in this example.

The light from the source hits the subject and is reflected toward your eyes at the speed of light.

That's why they call it the speed of light, and radio signals do it too between their source & receiver.

So now imagine you could travel faster than the speed of light to a planet a number of light-years away and you are going to get there from here.

Once you leave Earth orbit you will be able to accelerate up to and beyond c in the safest most gradual way directly toward your destination.

While still in orbit you look down on the traffic in your hometown, and everything is still moving at normal speed no matter how far it is down there, since you are a steady distance away from what it is you are looking at.

As you accelerate away from Earth and approach the speed of light itself you're beginning to catch up with the light that was reflected off your home planet quite a bit earlier than the light which is simultaneously being seen by those back in orbit.

So at half c you look out the window and it looks like everyone back in your hometown is moving at half speed. But naturally time marches on down there. You just can't be so sure any more. At that speed if you left 2 years earlier you will only be able to know additional things about your home which happened no more recently than 1 year ago at that point.

Of course you can't communicate with them about this in real time because of how long it takes the radio signal to get back & forth so you don't bother.

You keep going and reach full light speed which finally matches the rate the images are being reflected away from the Earth at, so now look back home and everyone appears to be standing still on Earth, as expected. Even though as far as you know they are still carrying on like normal.

OTOH, approaching the destination planet at the speed of light, that's pretty fast, but you have to realize their alien traffic is actually only moving half as quickly as it looks from your craft, whilst you are speeding so rapidly in their direction. Don't let that fool you, the aliens are only half as advanced as they look.

If you want to really see something, go faster than the speed of light and the planet you are approaching will be moving more than twice as fast as normal, and looking Earthward all you can see would be things moving backwards.

One thing that's happening is that you are always seeing images of these two planets where the light source originated from two different suns.

Once the distances get far enough, it's possible to launch a mission to a destination that actually no longer existed any more for quite some time before launch, only who knew?

In that case the earlier you make your reservations the more unwise it could be.

Since you could have transmitted potentially deadly diseases to immunocompromised people before COVID, you have definitely worn a mask everywhere in public for your whole life, right? That’s the only way you have any sort of moral high ground.

If the answer is “no”, then we are just quibbling over what constitutes an acceptable loss of life. Because you are culpable.

> Now suppose you understand brown as a "dark beige"

I think my point is brown is dark beige, and beige is light brown. Neither is canonical. Is orange canonical? Maybe it's high frequency red? Or low frequency yellow? That's what Newton thought! It's all relative.
Yes, 99.5% counts as “mostly”, I was just emphasizing that “I don’t want to wear a mask” is “I don’t care to protect you” not “I don’t care enough about the risk to myself too wear a mask”.
So you're okay with increasingly stricter subversion of freedom, because you've consumed media fear-mongering about the pandemic. The pandemic is not deadly enough to justify building a totalitarian regime.

What would have been the case if you asked the majority of Germans what they thought about certain restrictions in the 1930s?

Democracy is more than the "whole community setting the rules for the community." It is the rule of law in preserving the rights to life, liberty, and justice for all people. In the form of negative rights and the freedom to live as an individual unfettered by a mob of the majority. What you are describing and proposing is mob rule that subjects the 49% or fewer to tyranny.

And actually, what you're describing will subject 99.99% to tyranny because you are building a system of enslavement that will serve just the cream of the crop and crush everyone else.

Say it out loud. "They should have listened and the regular security guards should have been complaint! Now we need to use military officers to patrol and enforce." Say it out loud so you can hear what you're actually saying.
If you won’t provide proof you can substitute a weekly negative test.
Exactly, for the life of me I cannot understand why some people just don't understand that. It's tragic really because many people have lost their lives through the bloodyminded actions of those who who've callous regard for others.
> Would you agree that many or most of the other hues give you a colour more obviously 'dark X'

Hmm not really. But we're not going to resolve what seems like a subjective question!
I have my own opinions about the wisdom of the courts. There are plenty of countries where religious beliefs are given far less leeway to interfere with secular contracts and associations, and many of those countries are still fine places to live. IMO, that's the proper place for religion, but there would have to be much abuse before we countenanced going in that direction in the US.
You are cherry picking from the comment (and the article):

> the key thing is that another employee did get an alternate background check

It doesn't matter if it's a religious belief that you approve of or not. The point is it was possible but was not offered as an option for this person.

I think just like all things on the world wide web, a majority of it will be implemented sub-par, perhaps even terribly. It's not so much WebGL that is the bottleneck as all the experimental implementations of it (guilty as charged here).

Those people like Mr Simon here who take the time optimize every last bit can indeed make it purr.

Everything on the web starts as a framework or some proprietary bundle of some kind, and if it proves it's merit, it may just get built into the W3C standards themselves.

We currently have a low level tech (webGL) in W3C, and libraries like three.js are providing the get-you-by to elevate it to average code legibility, but I think we are still a long way off from having 3D be a javascript-native ability for the average developer in a peformant implementation, at which point we could really expect this www-metaverse experience getting hyped every which where to blow the lid on this two dimensional web we're currently stuck in.
> But Australia isn’t violent, divided, and less trusting of one another. Neither are most of the western-style developed countries that turn to the state for protection.

I didn't say they were.

> Have you actually been to Australia before? Or Europe for that matter? Or Japan?

Yes, yes, yes. Worthless rhetorical questions.

> Your claims don’t make much sense with the current examples.

What claims?

> All we have is a developed country that heavily values the right to bear arms and has a horrible crime rate, while the other countries are the exact opposite.

I'm not sure what you're getting at, but Europe is not a country. And there are more countries than your examples with differences in crime rates and gun ownership, so I suspect whatever point you are trying to prove with selective data points wouldn't actually hold up.
No. Though the new proposed? OSHA order may change that
That's basically what Canada did with the Grand Banks in 1992. They didn't ban fish imports, but they did deploy the navy to prevent other countries (eg, Spain) from continuing to fish there. This absolutely devastated Newfoundland's economy, and even with unemployment insurance, the population dropped because people left to find work.

I don't think a few years would cut it, the Grand Banks are juuuust starting to come back after almost 30 years of nearly no fishing.
I started one myself, too, more than twenty years ago, in a naive burst of enthusiasm about the potential of online collaboration. It was an attempt to create a new comprehensive Japanese-English dictionary from scratch, not based on existing dictionaries [1]. Other volunteers were equally enthusiastic, but the immensity of the task before us, and the competing time pressures of paying work, caused us to gradually stop working on it.

The article says that there are no ICU beds in "every major Tennessee metro area." The TDH dashboard you linked to says (today) that 4% of ICU beds are available statewide. Given that ICU bed use is almost certainly not entirely uniform statewide, and that it might be expected to be highest in metro areas, it seems entirely plausible in light of the TDH data that there are no available beds in metro areas--or at least close enough to literally zero that Tennesseans should be very worried.
> If the unvaxxed are only 11x more likely, then the vaccines do not work as advertised.

Something that reduces your chance of dying by 11x is something that works. Why do anti vaxxers use binary arguments so much (it must make me completely immune, or the vaccine is worthless!)?

Of course you can. That is what government statistics and academic studies are for.

But the source here, I believe was from an executive of a pasta factory.

It would be surprising to me if essentially all the pasta in Italy was made by one producer and sold at one price, such that you could talk about trends in fractions of a Euro based on one interview like this.

I'm used to staples being sold at different price points within a grocery store and across different stores or different communities.

Not a range of 40-80% like your sample numbers, but 300% or more.
This was probably downvoted due to the mention of GMOs but I think it is not unreasonable to be concerned about these.

Deaths per capita in Australia is at 10% of the US. If the US had managed to keep things as low as Australia, there would be just under half a million less deaths.

Seriously. Half a million. And for that, you won't stay inside your house for two weeks, because you're worried it's a slippery slope of some sort.

What need for me to be gullible to think "I'd rather five hundred thousand less of my countrymen had died this year", and not go out?

What need for me to be gullible to think that you should do it to? What need for me to be gullible to look at my government forcing you to do it too and saying "that's a good move"?

The quarantine system is quite literally saving lives, and the things that we can do to improve that system should be done.

This is not trusting the government, and it's not "ignoring tyranny". It's how society ought to work.
Those systems will not go away once they are implemented. Power will consolidate. It is a system of enslavement.
Failing education is certainly a big problem (and I financed a tiny reform school for five years trying to combat the tiniest of slices of it) but you are missing the power of reach. Not even Edward Murrow could dream of the reach of Facebook.
You're describing any hegemonic power structure. But my point was not that Democratic/Republican parties are worse than the CCP (on domestic power at least - they are worse than the CCP on foreign policy, but I digress...). My point was that it is easier for Americans to make change in their own country. So why not start there? That's something Americans (and people from US-aligned countries, to some extent) can actually do something about. The CCP is much harder problem that requires international solidarity to overcome. We need to set a positive example for dissidents in China, beating the war drums will not help them.
That proper time is zero everywhere along a photon's geodesic does not mean that the photon cannot evolve from point to point along it, and we can show this by taking advantage of total coordinate freedom.

We can parametrize (as in make parametric) arbitrary curves through spacetime however we like. Parametric representations of unique curves are generally nonunique.

Some of the infinite possible parametrizations of a chosen curve have useful properties, such as uniquely labelling every point on the curve with some monotonically ordering value and keeping the form of some set of equations reasonably simple.

For timelike geodesics, particularly in the Minkowski space of Special Relativity, proper time (being a Lorentz scalar) is a good option. However that is not true for all geodesics in Minkowski space (as you note, the proper time is everywhere zero on a null geodesic, and so a bad option), much less all curves through general curved spacetimes.

For null geodesics, following the logic of GP's question, we may wish to preserve the tangent vector under parallel transport; this requires the parametrization to be affine. Some gory details at https://en.wikipedia.org/wiki/Geodesic#Affine_geodesics and a brief useful summary at https://www.reddit.com/r/AskPhysics/comments/9aenid/what_act...

As is noted below the comment directly pointed to by the second link, labelling a timelike geodesic with proper time is choosing one specific affine parametrization on that geodesic, and that this choice is driven by convenience.

One of the neat outcomes of affine parametrization is that we can take a point on an affinely-parameterized null geodesic and look at the derivative with respect to the affine parameter there, and define a momentum k^{\mu} = \dot X^{\mu}. In a Lorentzian spacetime, with curvature, we can compare the momentum at two different points on the null geodesic, giving us the gravitational redshift between those two points of the photon's wavelength equiv. frequency.
> It is the article's headline, and there wasn't enough space to edit in the specific state.

Sure - I noticed that and wasn't implying that you modified the article title. The article title is incorrect, at least in the way it reads at first glance - yes the South Australian government is "an Australian government", but it's not "The Australian Government".

> But is it actually a meaningful distinction as far as these policies being constrained permanently to just one part of Australia? Will this spread everywhere or is there a reason why this would only be constrained to a really small town no one really notices?

It's too early to tell - but it's worth noting that the main revenue generating states with the lion's share of attention in Australia are New South Wales and Victoria and so they usually set the tone of state policy countrywide. IMHO this is unlikely to spread to those states.

More importantly:

1) the article indicates that its use will be voluntary anyway;

2) Australia has a long track record of paying millions of dollars for technology like this that actually never works properly.

So as a Victorian I'm not too concerned.
Is this a plist?
Unfortunately that's not how it works in the real world. Since the virus is now endemic, the chance that vulnerable people will be exposed over the next several years approaches 100%. Reducing R0 only slows down the spread a little. We don't have a practical way to reduce it below 1.
Work ticket ID (e.g JIRA number) in the commit title helps associate commits with PRs and the related tickets.
I think its somewhat reasonable that he knew it had short term issues at high concentration but believed that the body would flush it out on its own. And not that any exposure caused permanent damage.
What would it take for antivaxxers and climate science deniers to ‘wake up’?
Given that vaccination significantly decreases an individual's risk of hospitalization and that only about 40% of Missippippians are fully vaccinated, it seems like we would be justified in inferring that the people filling the ICUs are generally unvaccinated, no?
> you can’t tweak any of the three parameters in either direction without going out of gamut

This is a good thing: it teaches you the shape of the gamut, and gets you working with colors consistently.

#FFFF0O does not have “plenty of practical value”. It is a very niche tool with an extremely small range of uses, and should be avoided almost all of the time.

> For colour pickers especially, perceptual colour spaces have just been no good,

Just the opposite: for color pickers especially, using anything else makes it much much harder to get good results.

> This was his job. With his private sector employer. Who paid him money in exchange for services.

Who then changed the agreement from not even mentioning requiring fingerprinting to absolutely requiring it. That's the most egregious bad-faith example in this story.

If a business can arbitrarily declare "You now all need to pass background checks including fingerprinting to keep your jobs", what's to stop them saying "You now need to accept getting paid half of what we'd agreed to when you were employed"?

There was an employment agreement, the employer wished to add conditions to that after the agreement was reached between the two parties. And there apparent "re negotiation" of that agreement was the company saying "OK, you're fired". And the EEOC and the court both decided that was not OK. Which seems like the right outcome to me, regardless of whether the "religious discrimination" makes any sense or not. I'd totally expect the prosecution lawyers to play whatever the strongest argument the law had available to them. I would totally let a lawyer convince me it was appropriate to claim I have a christian belief and that part of that means I do not want to be fingerprinted, if that allowed them to use the most powerful legal argument against an employer who had arbitrarily and capriciously fired me on the spot for resisting being fingerprinted to keep the job I'd had to 16 months without that requirement.
They don't say it out loud. But they act based on that principal.
These logs? Check them.

journalctl --user -b -u pipewire
journalctl --user -b -u pipewire-pulse
journalctl --user -b -u pipewire-media-session

I also have this from earlier when I had errors; now I use it only right after startup because I'm doing output to multiple audio cards simultaneously.

systemctl --user restart pipewire.service pipewire-pulse.service pipewire-media-session.service ; systemctl --user restart pipewire-multi.service

(The -multi one is a local service based on the guide for multi-output audio.)

If you see log entries similar to: pipewire-pulse[1173]: client 0x55f2d47effa0 [Firefox]: stream 0x55f2d484f7d0 UNDERFLOW channel:0 offset:221184 underrun:16384

I fixed this for multi-output audio by 'increasing the headroom'

cp /usr/share/pipewire/media-session.d/alsa-monitor.conf ~/.config/pipewire/media-session.d/
vi ~/.config/pipewire/media-session.d/alsa-monitor.conf

There's a section near the end for alsa_input and alsa_outputs, WITHIN actions update-props, I un-commented and set:

node.pause-on-idle = false
audio.rate = 48000
api.alsa.headroom = 1536

However I believe that's specific to my multi-audio output setup and a mixture of different soundcards; I could probably hunt for a lower headroom value.
Looks quite good. Reminds me of the R Bookdown project (https://bookdown.org/).

Given the choice, I think most people would choose the app option and to isolate in the comfort of their own home.
Yes, it is. But if those that wielded state power (or significant cultural influence) were motivated by that, we wouldn't be having this conversation.

On the matter of measurable outcomes of social inequality, it seems logical to me that the larger the demographic[0] that is mistreated, the larger the measurable effect on society itself. This beside the ethical matters, which clearly do not motivate enough people, alas.

0 - I was tempted to put "minority" here, but women aren't a minority, now are they?
I have had this begin to happen and the quality of results has taken a nosedive in the past 6 months. A good example would be to search for something in quotes that has multiple meanings. Ex: I was having issues with Chrome leaving around RDP-TCP### folders on terminal services boxes. Try as I might Google would not properly interpret "rdp-tcp" as a folder name and instead gave results about the tcp protocol and RDP. Searching for info on temp profiles only gave me info on roaming profiles. Eventually said fuck it and wrote a scheduled task to remove the files because I couldn't find any information on Google.
