  • Thanks for the clarification, pipes look like copper but might be cast iron.

    Still doesn’t fit with the explanation, aluminum has more resistance than copper, but not that much more. The resistance of cast iron is an order of magnitude higher than aluminum. So it would still be the lowest resistance in the circuit and thus the coolest part.

    And cast iron is pretty good at conducting heat. Not as good as copper or aluminum, but still pretty good. We’ve been using the material to make pans and pots for cooking because of it’s thermal properties. So the heat wouldn’t just stop at the fitting, but continue on at least some ways.

    Moreover it’s physically impossible to get aluminum hot enough to glow like this and still keep its shape. It melts at 600 degrees C, well below the point where something gets red hot, let alone yellow like this. If the aluminum were to be this hot, it would be in a puddle and at risk of burning.

    This makes no sense at all.

    Why would only these two specific pipes get hot, so hot to glow, but not the other lines connected to it? And not the fittings around it? It’s all copper, so even if the power itself doesn’t heat them up, why would being connected to an extremely hot pipe heat it up. Since it’s you know copper and being good at transferring heat is what it’s known for.

    And why would the lower resistance part be the part that get hottest? Low resistance means less loss, so those parts would in fact be the coldest of all.

    Plus thin walled copper pipes can’t get so hot they glow without melting or at the very least lose all structural integrity and break.

    And a downed power line with a short to ground would almost immediately turn off. It’s when there isn’t a direct line to ground those things are dangerous. As soon as it shorts, it gets turned off at the source to prevent further damage, fire and not cause issues upstream.

    Either it’s Photoshop or someone has wrapped led lighting around some pipes.


  • No, you misunderstand. You get seconds assigned to your token. It doesn’t matter where in the video you use those seconds.

    So if you watch an ad you get say 60 secs of video until you need to watch an ad again. You can watch 30 secs, then skip 2 minutes ahead and watch another 30 secs, then you get an ad. In reality the times would be larger, but to illustrate a point.

    In the current setup YT uses, if you watch an ad, watch 2 secs of video, then skip ahead of the next adbreak, you get more ads.

    And yes as stated, a separate client can get around this. But as also stated there will always be ways around it, it’s just a matter of making it harder. If it’s beyond what a simple browser plugin can do, it’s good enough. And YT has been banning 3rd party clients anyways, so that makes it even harder.



  • Yeah I’m thinking of a system like this:

    A user opens a session to watch a video, the user is assigned a token to watch the requested video. When the user isn’t a premium subscriber and the video is monetized the token is used to enforce ads. To get video data from the server, the user needs to supply the token. That token contains a “credit” with how many seconds (or whatever they use internally) the user can watch for that video. In order to get seconds credited to the token, the user needs to stream ad content to their player. New ad content is only available to stream, once the number of seconds they were credited have been elapsed.

    One way to get around this is to have something in the background “watch” the video for you, invisible, including the ads. Then records the video data, so it’s available for you to watch without ads. But it would be easy to rate limit the number of tokens a user can have. There’s ways to get around that as well. But this seems to me well beyond what a simple browser plugin can do, this would require a dedicated client.

    The idea is to make it harder for users to get around the ads, so they’ll watch them instead of looking for a way to block ads. In the end there isn’t anything to be done, users can get around the ads. Big streaming services use DRM and everything and their content gets ripped and shared. With YouTube it would be easy for someone to have a Premium account, rip the vids and share them. But by putting up a barrier, people watch the ads. YouTube doesn’t care if a percentage of users doesn’t watch the ads, as long as most of them do.

    My point was, there’s ways to implement the ads without sending metadata about the ads to the client.


  • I’m not talking about the player or the controls being server-side. I’m talking about the player being locked into a streaming mode where it does nothing but stream the ads. After the ads are streamed, the player returns to normal video mode and the server sends the actual video data.

    This means no metadata about the ads are required on the player side about the ads.

    Sure you can hack the player into not being locked during the streaming of the ads. But that won’t get you very far, since it’s a live stream. You can’t skip forward, because the data isn’t sent yet. You can skip backwards if you’d like, with what’s in the current buffer, but why would you want to? You can have the player not display the ads, but that means staring at a blank screen till the ads are over. And that’s always the case, one can simply walk away during the ads.

    Technically I can think of several ways to implement this, without the client having meta data about the ads. And with little to none ways of getting around the ads. Once the video starts it’s business as usual, so it doesn’t impact regular viewing.




  • Oncoming drivers? I’m getting blasted by “cars” behind me. Fucking trucks or even lifted trucks with their headlights at my eye level. And it seems like lights are getting brighter as well, or people drive with their high beams on. My rearview mirror is auto dimming, which helps a lot. But since I drive the speed limit these trucks are swerving back and forth behind me, blinding me via the side mirrors.

    Man we really really need restrictions on size and weight of cars. It’s getting ridiculous out there.

    People call 911 because they are having a medical issue, cops show up and shoot them and their dog, plus the neighbors dog for good measure. Shitheads actually attempt a coup, try to hang congress people, invade government offices, somehow only one of them gets shot. It makes 0 sense.


  • Really I’m gonna need a source for that old timey radio claim. Because that sounds like it’s made up and even if it’s not, correlation does not mean causation.

    There is no known mechanism for non ionizing radiation to have ANY effect on the human body or individual cells besides from a warming effect. And even the warming effect is quite small, there are normally a lot of other factors that have a way bigger effect on the temperature. See the Mythbusters episode where they tried to warm a chicken on a radar emitter. The turning of the radar cooled it down more than any warming from the radar did.

    If there is any truth to claims that non ionizing radiation harms humans, physicists would be all over that. That would mean new physics in an area where there hasn’t been any new stuff for a long time now.

    But it turns out we understand it pretty well and see no mechanism for any harm to occur. In that context all of the studies that find no relation are meaningful. If there seems to be no relation and there isn’t a mechanism to do anything, why would anybody think there is anything to find? Turns out it always comes down to FUD, to further some kind of an agenda.






  • I know a lot of folk that work at MS or have worked there, they are all very good people. They are highly motivated professionals that are top in their field. MS is a rich company and they recruit the best they can. However those are not the people making any kind of decisions. And it’s a cut throat company, if the budget gets cut, you are out on your ass. At least in most of the world, where strong employee protection isn’t a thing.

    Don’t get me wrong, MS has a lot of bad apples just like any other company. Useless managers who say dumb shit and take praise for other peoples work. A leadership that doesn’t care about anything except their bonuses and the bottom line. But at least as far as the engineers go, there’s plenty of really good folk.

    People also seem to forget how huge MS actually is. And a lot of the time the different branches within the company are as far away from each other as can be. Even within the same branch one can only talk to so many people.
