    The problem is that nobody, apparently not even manufacturers anymore know how to fucking aim headlights. Headlights literally have aimer knobs and you are supposed to aim them such that they cut off just before they would blind the majority of vehicles

    I have projector LEDs and with a projector lens you can get an extremely practically knife sharp cut off and I have it literally just at the very bottom edge of most small sedan windshield lines. It’s great my headlights are bright as fuck they go all the way from the left shoulder to the right shoulder even on four lane roads but they don’t blind anybody and I’ve had friends help me test that by just kind of passing each other on the street and them saying it was fine and wasn’t bad like other people’s cars.

    At some point people started associating the height of your light with the amount of safety, it’s possible to get distance without adding height but everyone’s forgotten how that works




  • They get upset about it because it’s a trend in the industry that a lot of people hate. That particular series is a great example where the next game not only adds nothing but even generally takes stuff away from the previous title, but it keeps selling so it’s kind of becoming a trend in the industry for most series to just keep releasing the same garbage over and over.

    So it’s less about enjoying a sports game that they are upset about, and more upset about encouraging the behavior of extremely low effort recycled releases constantly



  • I am the one that posted the question on that product, the answer came the next day. And I can confirm from having gotten the emails asking for answers to questions in the past that the email asking the question provides you an image of the item and description so even if the listing had been flipped it should have not shown them the dash cam in the email asking the question.

    But yes sellers do like to do that to make reviews look good, he have to be careful to actually read the reviews to look for someone describing the product to make sure it matches





  • Off-grid inverters bypass a LOT of that. And i should have been more clear on no backfeed. I would never recommend backfeed tbh. It comes with insane amounts of red tape, as you’ve noted, the equipment is also much more expensive for grid tie.

    Off-grid inverters are basically a backup UPS on steroids. They accept grid as an input but don’t feed back to it. They have far less regulation on their installations. Some places indeed you will still have some but usually you can get away with just having the final install inspected by a master electrician.


  • If you do it yourself it can be so much cheaper, For example with a goal of about 20k spent This bundle gets you 12Kw of inverter output and 30Kwh of batteries for 11k. Then just grab two Of these solar panel pallets for 28Kw of panels. Or Alternatively go smaller with just one pallet and save a bit. Then ofc you will get the 30% federal tax credit on top of everything

    Not everybody is going to want to do it themselves I get that, it’s actually very easy and straightforward I posted another comment here up above that goes into more detail but honestly just about anyone could learn to do it it’s not advanced electrical work by any stretch of the imagination.


  • To be fair this is just if you pay professionals to do it. They charge astronomically out the ass for labor for no reason. The actual cost of the equipment is surprisingly little if you buy it yourself, and installing it is very straightforward and easy you do not need to be particularly intelligent or skilled. I’ve done about five different systems at this point, two on RVs and three on houses. One of the houses and one of the RVs was my own and the rest are friends that I have helped set it up.

    For example with a goal of about 20k spent This bundle gets you 12Kw of inverter output and 30Kwh of batteries for 11k. Then just grab two Of these solar panel pallets for 28Kw of panels. Or Alternatively go smaller with just one pallet and save a bit. Then ofc you will get the 30% federal tax credit on top of everything.

    Ask any installer for a similar sized system and it’s almost certainly going to be 80k+ at minimum. The only part you may definitely want a professional for is if you plan on roof mounting them, have a roofer come help install the framing so you can ensure no leaks. But for ground mount (or if you are familiar with roofing) even that’s not needed.

    The actual electrical works is very straight forward. Everything is very clearly labeled, the documentation is very explicit about what goes where. On the solar panel side you’re literally working with DC so you’re literally only dealing with positive and negative. Even on the AC coupling side when you’re talking about an off-grid inverter you’re not back feeding into the grid so it’s very straightforward. Your house grid goes into the input, and your output on the inverter goes to your panel.

    The only stuff to watch out for in the NEC is rules about where your secondary panel for the solar output can be placed, has to be a certain distance from the ground, has to have a certain amount of clearance around it on all sides, has to be accessible, stuff like that but it’s all fairly easy to just look up thankfully






  • Your not too dumb to learn linux. I know it seems scary, and a lot of the autistic people that like it will try to convince you it’s only for really smart people. But at the end of the day a lot of basic tasks are actually easier on linux. There are some that are harder gaming used to be very difficult for example. Although thanks to valve, and the steam deck for the most part if it’s a steam game you can just click play and it’s probably going to work.

    But as an example of a more basic thing, let’s say you want to install an application.

    Windows: go to Google, type app name, make sure it’s the real actual website officially for that app and not a sponsored result or some other fake website, find the download, pray it’s not buried in a bunch of fake download buttons, double click the exe, be careful to make sure it’s not installing any toolbars or other packaged bullshit, finally get your application.

    Linux: there are some variations (apt dnf pacman) but all of them work the same, for arch it’s “pacman -Syu <name of app>” id argue thats WAY easier. If it’s not in the main repos chances are high it’s in the AUR (arch user repository) so you just yay -Syu <name of app>. It’s not harder (imo) just different.

    I’ve actually had a number of pretty average computer user friends let me help them transition to Linux because of the crap Windows is doing lately. And after getting used to the differences they agree that Linux is not actually harder, it’s just different, they grew up with windows, they are used to how things are done on windows, so it seemed difficult just because it wasn’t the same. But once they got used to it they would actually agree that a lot of things are actually easier.

    Now whether or not you want to put in that time to learn those differences, and change how you use your computer, is an entirely different question that you have to ask yourself. But you are not too stupid to learn Linux because realistically it’s not any more difficult than Windows is





  • Everyone always thinks the jewelry when they think of diamonds but I am excited for the prospects of what cheap lab-grown diamonds can do for manufacturing. Diamonds are electrically insulative and yet 10 times more thermally conductive than copper. There are a LOT of industries that would be VERY interested in that.

    Hell, it would probably be useful in CPU substrate as well. Instead of silicon semi conductor doping if these could be made precisely enough you could use diamond for the insulation layers and gain that insane heat transfer efficiency to help with avoiding Hotspots. Maybe that’s too thin to matter that much not sure
