  • 9 years and 4 months ago I bought an Acer laptop with a 4 core Intel Skylake with hyperthreading (i7-6700HQ) and a Nvidia GTX 960M, because the laptop I had was slow for compiling in my classes at Uni, and I wanted a discrete GPU for the occasional game when away from my Desktop PC (winter break and such (still use it for that btw)). I regretted that three times:

    • First when I wanted to install Linux instead of just using VMs. In early 2016 the kernels on live system ISOs didn’t properly support Skylake yet, so I fucked around with Arch a bunch, but didn’t end up keeping it installed. Don’t remember why, probably got busy with schoolwork.

    • Then a while later, after I had installed Ubuntu or Fedora at some point, the next issue was that cooperative mode of Bluetooth and Wifi on the included Intel wireless chip wasn’t well supported (even found an Intel Bluetooth dev saying as much on a mailing list), and it hung sometimes, so I had to make a script to turn the chip off and then rescan the PCI bus, that worked as a workaround but was still annoying.

    • Finally when we had Machine Learning classes I thought I might be able to use CUDA locally, so I tried installing the proprietary Nvidia driver and was greeted by a black screen on the next boot. Had to boot from a live system and chroot in to remove the proprietary crap again.

    On my Desktop PC I have used AMD GPUs for quite a while and dual booting Windows and Linux has always been a breeze.















  • You probably mean the sales taxes, those look similar from a consumer point of view, but they work differently.

    In a VAT system the taxes are collected all along the value addition chain. Each sale of intermediary products has the VAT cost on it, but companies can claim the VAT that they pay for their inputs against the one they collected on their outputs. In effect each company hands over the part of VAT that is raised on their part of the value addition. In the end it all comes from the consumer who buys the final product but doesn’t sell anything onward so they can’t claim their paid VAT against anything. This system determines the end consumer automatically.

    In a sales tax system, only the sale to the final end customer is taxed, and intermediary products are not taxed. Intermediary companies must prove to their suppliers that they are not end customers, that they intend to sell things onward, and that they are therefore exempted from sales tax and the supplier does not have to collect sales tax. If that fails, then that means mistakenly a company has to pay sales tax, and then their customer has to pay it again.

    Other than that I don’t know enough to compare:

    • What is more or less administrative overhead.
    • What is more or less open to fraud.
    • To what degree this is linked to the existence of a single national or many regional tax rates
