  • In North America and Europe, tap to pay was implemented prior to smartphones that could scan QR codes being ubiquitous. Most of us have had cards that support NFC payments for longer than we have had a phone that can read QR codes so it made sense for phones to pick up the technology that worked with the terminals businesses already had than try to implement a new system.

    The QR code thing is primarily a Chinese solution to the payment problem (all other Asian countries I’ve been to have widespread NFC acceptance). Payment cards were never widespread within China the way they are in other places, until AliPay and WeChat Pay became a thing people still primarily used cash for their daily communications. If businesses don’t already have credit card terminals but people have smartphones then the QR code starts to make more sense.

    One interesting thing about this is that even before North America was widely using NFC payments, people in Hong Kong were using their Octopus transit cards as contactless payment at all kinds of businesses throughout the city. Yet that technology didn’t seems to make it into Mainland China.




  • now on the 4th update it keep failing for some reason.

    Running an Arch based distro comes with a commitment to learning “the Arch way”. You need to be willing to look at the terminal output of pacman and see what the errors mean. Being close to bleeding edge means that on occasion something will fail or end up in a state that you need to resolve. Its usually easy, but you need to pay attention to what pacman is telling you. If that isn’t something someone is interested in there are plenty of other excellent distros out there that will meet their needs.










  • Smart Homes arent terrible, but it is easy to end up with a terrible smart home if you don’t take care in designing it.

    Consider who is using it. Are they tech saavy enough to use an app? Is every user only within your household? If not, make sure everything can be controlled without an app, smart buttons are a great solution. What automation actually benefits your lifestyle? Keep it simple where possible, start with just lights and maybe some sensors.

    I think it is best to have an overall plan to make sure your devices work together, but start small. Choose devices that run on stable platforms and locally. Make sure everything can connect to Home Assistant, even of you don’t plan on using it, having the option may benefit you in the future.


  • I typically build a whole new PC and then do a mid-life GPU upgrade after a couple generations. e.g. I just upgraded my GPU I bought in late 2020. For most users there just isn’t a good reason to be upgrading your CPU that frequently.

    I can see why some people would upgrade their GPU every generation. I was suprised at how expensive even 2 generations old card are going for on ebay, if you buy a new card and sell your old one every couple years the “net cost per year” of usage is pretty constant.
