  • The install instructions for the clip on band has you cut the original pleather and foam off the band and peel away any adhesive. The irreversability of that made me nervous for no rational reason. So I opted for a cover similar to these ones from wicked cushions.

    There also seems to be plenty of similar options on aliexpress.

    It just zips on which is a suoer easy and quick install. I liked that I could just quickly try this before committing to a biggger repair. My only complaint is that the zipper pull dangles and that could be annoying. I used a dab of liquid electrical tape on where the pull meets the slider to prevent any rattling. An unexpected pro/con is that the silicone grips my hair more. That can be a slightly uncomfortable annoyance at times, but it does help the headphones stay in place better when laying down.



  • Sony parts prices are insane. The urethane pleather on my headband started cracking on my xm4’s. A replacement headband was half the price of a new unit. So I ended up getting a silicone cover that will hopefully keep the pieces from flaking off into my hair. I also needed new earpads. Oem pads were around $40 for EACH side. The pleather just has a certain degradation time and once it hits, it all falls apart at the same time. Replacing all the pleather parts on my unit would have cost just as much as a new headset.

    I hate having something designed to be somewhat repairable but practically speaking it isn’t due to pricing.




  • The supply side of power generation is coordinated by a bid system. So the cheapest sources are activated first. As demand goes up increasingly expensive forms of power generation are turned on.

    For daily and seasonal variation, this is fine. The amount of time that really expensive generation is active is only a small portion and the base rate can stay low. However, if you add a bunch of baseload without adding equivalent generation, your utility will be stuck buying at the top end of the capacity market auction. The datacenter will have negotiated a discounted rate though because constant demand is good for the utility in the long run. That leaves everyone else paying a big rate increase.

    Source: none given, but the capacity auction is a real thing, and the predicted behaviour of such a system can be reasoned.

    Yeah. Who buys a pumpkin for it’s literal value as a food item? There’s canned pumpkin for that. Anything to do with buying a whole pumpkin is all about maintaining an experience and tradition. In that view, pumpkin carving a storebought pumpkin is the base experience, and going to the pumpkin patch is the extended experience. People can choose the level that matches their enthusiasm for fall festivities. Neither purchases are practical, but both can be worthwhile.

    I don’t see this as much different as the buying a CD vs concert ticket mockery. Concert tickets are always economically an impractical purchase vs buying a copy. People don’t go to concerts to get a good deal, and there’s just as much crap to deal with as the muddy parking lot and unsocialized animals of a pumpkin patch. People go to concerts for a specific experience that brings them joy and forms memories. Mocking that desire is silly.











  • The speed of sound in seawater is around 1500m/s or 5400 km/hr. Something tells me they won’t actually be going supersonic.

    The article shouldn’t be referencing the speed of sound without specifying the medium for the sound waves and conditions such as temperature for water or temperature and pressure for air.

    Also, the supercavitation would be incredibly noisy underwater, and at those speeds the vessel itself would produce a very loud pressure wave that would be easy to detect. So its advantage wouldn’t be in avoiding detection, it would be in moving fast enough that detection doesn’t matter because no torpedo could intercept them.
