I imagine passengers will be exposed to very high noise levels during flight.


I don't have a good intuitive feel for that.

At 25km altitude, with 1% of normal atmosphere, maybe you're close enough to vacuum that it can get really quiet?


The engine noise can still be conducted through the body of the plane. With the kind of ramjet being talked about, I think that's still likely to be significant even at very high altitude.


This effect would help mitigate the noise heard by people outside of the plane (but I suspect that noise is negligible compared to the sonic boom), but in the plane the sound would mostly be propagated though the fuselage of the plane, not through air, so it's not going to help.


Makes sense and this is how we do it in Australia.


Sounds like something worth reporting as it is an offence in Australia at least. The police would certainly investigate such an allegation and charges could be laid if there was sufficient evidence and a conviction was possible.


> The police would certainly investigate such an allegation and charges could be laid if there was sufficient evidence and a conviction was possible.

I'll let you know when I finish laughing.

This is 100% false. You can serve up all the evidence on a silver platter the the police will ignore it. I know, I've tried, specifically in a stalking case. They don't care.


Maybe where things are different where you live.


After being stalked myself, for years, across borders, I can tell you the police doesn't care unless you can prove real, imminent danger. I have no idea how to prove that short of a written confession. A message from the stalker with a picture of them holding a knife at the door of my building, and the text I came to "visit" you but you had guests/witnesses for example didn't reach the bar of imminent danger.

The police is made of people who want to do the job but are swamped with bigger problems, and people who don't want to do any real job.


It's true in Australia, true in the US, true broadly in the UK and Europe. Where do you live where it's not the case? I once got mugged, had the perpetrator's ID and a video recording of them doing it, and they got a slap on the wrist.


Things are very different in the US. Police do not exist to uphold the law or protect civilians from anything. There are specific rulings in our legal code that flatly state police are not obligated to protect anyone.

Police in the US exist mainly to suck up tax money and harass and murder civilians and escalate peaceful protests into riots to justify suppression and murder. They're merely an instrument of an increasingly authoritarian government.

Yeah, if you gave police here a complaint with all the evidence in the world, there is absolutely no obligation for them to investigate or take any action. And there's really no recourse.

Be glad you live in a functional society.


Maybe you're being Naive? Just because there are laws doesn't mean there going to be enforced. Especially with what's going on right now with governments becomming authoritarian.


Ha. That's what everyone thinks before they've needed the police.


You're referring to the police, who are also abusing these surveillance systems to stalk their exes?

Or maybe federal law enforcement, who are also abusing these surveillance systems to stalk their exes?

Or perhaps intelligence agencies, who are also abusing these surveillance systems to stalk their exes?

Did I mention they're all friends with each other and usually help each other and cover for each other?


Yeah it was reported, but the telcos systems were such a load of slop there wasn’t any specific evidence recorded (logs etc), and besides nobody knew what to ask for, so it couldn’t be taken seriously.

I don’t remember the exact circumstances of how they got a confession years later, I think bragging, but he did get convicted and the Telco eventually fired him, which stopped the stalking.


What no log files of who's accessing records? That seems super sketch.


I’m spitballing here but it seemed like his job was a kind of ITS/technician job in the core infrastructure, and it seemed like he didn’t need to go through normal channels to get the information he wanted, ie he could just like pcap a tower with a filter or whatever in a routine kind of way that I guess didn’t create any specific logs. If there were any relevant logs they would have had to give them to the police. And I know that at a high level Telcos are heavily regulated, so there should have been logs.


Doesn’t surprise me at all. I signed up for an internet plan with a provider once, but they never let me login to pay the bills. After they started threatening me with collections and several phone calls layer it turned out they were billing someone in a completely different city. Complete shambles.


I have a comparable dispute with an old ISP from an old apartment. Their system had me as still receiving services there for many months after I cancelled and moved. Every year they send me a final warning saying it'll go to collections (the fact that it hasn't actually gone to collections more or less tells me I'm right, lol). Every year I'm grateful it's "just" an ISP and not the government because the government would've escalated the fine to a bajillion dollars and issued a bench warrant by now.


On the other hand, at least with a bench warrant you get to go to court and tell the judge "look, I cancelled this service years ago and I don't live there any more, and they confirmed the cancellation" and the judge would tell the opposing party to go cry about it.


Bad actors will buy data from people and places where they don’t care.

I've seen people getting fired in BigTech for using the platform to stalk their ex-es. It's usually an alert that goes off when employees access internal dashboards for a certain profile, too many times.


BigTech is far more competent than a Telco though.


having worked and consulted at both... debatable.

level competency is higher at BigTech but laziness, vanity, selfishness, ego, and learned-helplessness happens plenty too.

e.g. for all of the BigTech brilliance plenty of them fall for mildly complex phishing efforts or bribes, etc.


Some systems, like lawful intercept, are designed to be hidden even from telco network management systems. The LI console that set up a wire tap might log activity at that particular console at that particular law-enforcement agency. But if you don't know where to look exactly, good luck.

This is why the Chinese picked lawful intercept as a hacking target for the salt typhoon exploit. It's almost impossible to know whether that exploit is continuing or when exactly it began.


Someone else was targeting it long before the Chinese.


Cops are too dumb to comprehend that. They would proclaim it impossible and order more donuts.

Most simple criminals get away with their crimes. Anyone with any level of sophistication does as well.


We don't do this numbered street thing very much in Australia and manage to get around ok.


Yea ok, but move to a numbered city and you notice the boost. I’ve lived in Melbourne, Sydney, and NYC and found Manhattan’s numbering is great.

Lower Manhattan also still has a large non-numbered area so you can get the old charm when you want it.


Only place I’ve ever seen it is the main stretch along Palm Beach on the Gold Coast

1st through 27th Avenues - they’re over 100 years old now funnily enough


That's the deception plan.


The mix of imperial and metric units in this article was confusing.


I don't understand.


Author here.

It's a fun experiment into WebGL and graphics programming. I intended it to be a cool tool for getting inspiration for designing and creating other art in general. I do eventually want to build this out into a larger set of tools that would allow you to quickly iterate and build out various aesthetics for designing.

In it's current state, it's mostly practical for creating pretty images and videos that you could use in other projects. If there's more interest I could possibly turn it into more, would love to hear ideas and suggestions!


I think it's just a technological show piece, basically built on top of open source libraries and a couple of algorithms.


Author here, you're mostly right in that it's a show piece. However, it uses no external libraries, I built it all myself using VanillaJS. I do use some famous noise algorithms, specifically Simplex noise and a method of domain warping.


Lets let author explain. Our explanation might derail newbie readers


Same here


Author here, I've replied to the parent comment, hope that clears it up!


I have the Ford Ranger with the 2 litre biturbo diesel engine in Australia. It is so good it's hard to conceive that a better vehicle could be possible.


If that's the one with the wet timing belt, then I can think of one way to make it better!


There are 5 road bridges and 1 railway bridge in the vicinity of Narva.


This is good news. Punish the wrongdoers so we can live in a peaceful safe society.
