Who do you think was doing the screaming and crying in the video footage of the cops standing around if all the kids were already dead ? How come there were survivors of the shooting if all the kids were immediately dead ?

The ones who died while they were being pussies? While they waited what? 2.5 hrs with full tactical gear and guns? Absolutely they should be blamed for those deaths and they shouldnt have that job if they wont do it. Fire the whole damn department and the other ones who pussied out too.

It is, the just don't advertise them as such because that's not the target market they are going after.

Search for 'active hearing protection' and you'll find basically the same devices but for a different market.

Listen to the video:

The shooter unloads on those kids the second he steps in. I'm not saying the cops didn't make mistakes but most of those kids were dead before any cops arrived. He is unloading almost non-stop.

electronic storage is really optimized, from the hardware end, your phones capacity, to the software end, how the information is stored.

Yes, I get all weren't dead but is it fair to blame the cops for all the deaths?

I’m no scientist but yes to this response. It’s what I was thinking too.

Rail is complicated for different reasons. Technology isn’t the problem with rail. It’s the cost, getting the right of way, nimbyism, politics, environmental, and so on.

Have you ever seen a rail line built? They’ve been building a light rail line near my house since before I moved in 12 years ago and it’s not scheduled to finish for another 2 years. Funding and engineering went on for years before that.

Whatever new tech we need to get the trucks following each other will be done before this rail line. I think the technology is pretty close already. My wife’s 2016 Subaru has adaptive cruise control and lane assist which seems like enough to draft a semi.

> It is an entirely for-profit middle-man business run by the journal publishers

Plenty of prominent journals are run by nonprofit organisations - most learned societies have their own journals, for example.

> Journals take and take, and make everyone else pay for things they didn't create, with minimal operating costs -- all they have to do is host the research papers, and print some paper copies.

They also do copyediting, and gatekeeping to keep the cranks out. I agree that there is a lot of profiteering involved, but if the journals were pointless then everyone would just publish on sites like arxiv.

At some level, academics have to take responsibility for this problem. They're the ones who are choosing to pay to publish their work in crappy Springer/Elsevier/Wiley/MDPI journals instead of supporting their own learned societies or setting up their own more responsible publications. They're also the ones who obsess over publications and citations and tell the politicians that that's how they should be judged. This isn't a problem that is being foisted on academia from outside.

> I believe in the US, regulations are being put in place currently that force academic work funded by taxpayer money (a huge share of research funding!) to be made available free of charge to the public within a year.

Yeah, but these policies tend to result in one of two unsatisfactory approaches. Either the academic hosts a version of the paper privately, which often isn't quite the same as the "official" published version and can be hard to track down. Or they publish in an "open-access" journal, which brings its own problems. The open-access model is that you pay a big fee and they publish your article and make it available to everyone. This is basically the same as the vanity press model. Open-access journals have a huge incentive to publish as many papers as possible, and very little incentive to ensure their quality or promote them to a wide audience, exactly like vanity presses. Again, there are plenty of good, non-profit open access journals, but most academics prefer to publish in the endless array of Springer and Elsevier ones.

ArXiv is a big one. I'm in life sciences, and we're seeing the same with medRxiv and bioRxiv. For all the harm it did, the pandemic did much to drive adoption of these platforms. Though I feel many people still think of them as more of a stepping stone to that coveted Nature publication, etc.

Woah there Tex. Calm down. It sounds like you’re thinking I’m saying something that I’m not. We can have both. And I really rather like traveling on light rail.

But it’s said there wil probably never be another heavy rail line built in the us because of the cost.

I see, so vasoconstriction squeezes the blood cells that was initially unable to reach the heart due to low blood pressure and Thereby increasing preload?

[removed]

Well yes but how does increasing blood pressure and vasoconstriction lead to increased preload? Isn’t it just receiving the same amount of blood?

I grew up in Dundee - the Tay Bridge is about 1.5 miles long and sloped. We used to cycle across just so we could freewheel all the way back!

> then stood around for 20 minutes while the shooting continued

This makes no sense. 19 kids died. There is no way it took over 20 minutes for the shooter to kill 19 kids at point-blank range with an AR-15. I'm not implying the cops didn't make mistakes but the majority of kids had to die before the first cop stepped foot in the school.

> Schools arent prisons, or shouldnt have to be.

I'm not talking bars on the windows. Simple stuff like a armed security guard and locked doors should have been enough to slow the shooter down long enough so the cops didn't have to deal with a shooter inside a classroom.

ANC headphones may not be rigorously tested for hearing loss protection, but the perceived reduction in volume is real. As in, if it feels quieter for your ears, then you are protecting your ears from those sounds. As others have said, large transient sounds will not be cancelled as much, and you will certainly hear those as louder, and even possibly too loud.

I think the misconception might be based on knowing that ANC headphones use an equal but opposite sound to cancel the incoming sound. So twice the sound going into your ear must not be healthy. But the air pressure does cancel prior to reaching your eardrum. If you can't hear it, it's not hurting your ears, (mostly).

NC make opposing soundwaves but don't physically block noises. Fast cars, trash trucks make vibration I can feel when they pass. I'd need to physically block (earplugs) to reduce, measured in db on the package.

Turns a low pressure low volume system into a high pressure high volume system. Delivering more blood (preload) therefore hopefully (if EF preserved) increased cardiac output etc. I agree it's a bit tough sometimes to get it right in the head. Brings back days as a cardiothoracic jnr Dr.

Noise canceling headphones does have limits to what they can cancel out. The speakers and amplifiers in them have a maximum strength and the software and microphones have issues with some sounds. The noise canceling feature might even do some loud sounds worse. The background noise you hear when walking in public is usually low enough not to cause any sort of issues. The sounds which do cause damage to your hearing tends to overload the noise canceling features anyway.
