  • USB C suffers from distance degrading earlier in distance. https://community.infineon.com/t5/Knowledge-Base-Articles/Maximum-length-of-the-cable-for-applications-in-USB-Type-C/ta-p/250571.

    There is a lack of consistent standards. They’re all over the place and manufacturers just do whatever they want. Because of this, you can literally have only one cable or adapter that works for a device. In some cases, a third party cable can actually damage the device.

    My anecdotal experience:

    3.5mm to USB C adapter in three versions. I need one for an Android based tablet and a laptop. I have one from three different brands, Walmart, Apple and Google. The Walmart version works, but every single time you play audio from silence a pop is heard. The Apple version doesn’t work at all. The Google version works perfectly.

    For the USB cable itself, it’s rated at 100W and comes from BestBuy. My laptop detected that the provided cable isn’t their OEM version and limits power intake to 65W instead of 100W. My tablet uses the full 85W and my phone uses the full 18W from their respective chargers.

    One would be under the assumption that these products are universal, but this isn’t the case.




  • Some self hosted services refuse to work if you use a self signed certificate with your public facing IP. They only allow self signed certificates when using one of the handful of private addresses.

    Some apps on mobile devices for the service you use won’t work unless a trusted certificate is used. A self signed certificate behind the scenes creates an error that isn’t handled and you can’t connect.

    You lose the ability to have a proxy in front to handle abuse so your server is spared the headache. You need a domain to do this.









  • This is so far from the truth.

    The real reason is cars are heavier. The more weight, the more wear on the tires. You can only make a tire compound so hard before they become uncomfortable rolling chunks.

    In the 70s when the fuel crisis hit, cars were very inefficient. Heavy steel and heavy engines that guzzled field. As the technology has progressed we use composite materials to make them lighter where we can. Some of these materials are more expensive than others, so you won’t find them on all models. Magnesium and Carbon fiber for example. We started to make cars lighter.

    Then there’s features, creature comforts, etc. We started adding more and more fancy features over time. These all add up. Heavy sound deadening pads are placed all over the bare chassis. Rip up your car’s carpet, underneath you’ll find them. They’re in the door and behind the dashboard. There’s even foam in the A, B and C pillars. We figured out that we can make cars quieter. Now that we can make them quieter, let’s add a lot of creature comforts. Power, heated seats and mirrors. Power windows, powered lift gates, and anything else that’s powered. These require electric motors. Not sure if you’ve ever seen these electric motors, but these are actually quite heavy little things. A few speakers is now almost a dozen in many models. Lots of trim pieces that make the car more aesthetically pleasing add weight.

    Safety is a huge factor as well. One or two airbags has turned into about a dozen. Extra beams that are used to dissipate energy around you in a crash. My car has 8 alone for just the front driver and passenger.

    Got a hybrid or an EV? These absolutely demolish tires because the additional components adds a lot of weight.

    Even though we got better at making composite materials and reducing weight where we could, our need for creature comforts and advancement in technology has caused the overall trend for a car’s weight to go up. This information is readily available if you’d like to search the Internet.

    A set of tires wear endurance has only gone up over time. But because of a car’s weight, it reduces its ability. Your driving habits also greatly impact how long your tires will last. Do you have a Rivian or Tesla? Go easy on the acceleration and showing off with the spirited driving. You can make your tires last less than 10,000 mi. Do you add additional weight? How long is that additional weight being hauled around? In other words, if your trunk is full of stuff, clean it out. You’re increasing fuel consumption and increasing tire wear.
