  • You need sampling at twice the frequency as a minimum to extract a time domain signal into the frequency domain. It says nothing about “perfect” especially when you’re listening in the time domain.

    Yes it does. You can use a higher frequency, but that does not change anything except increase the maxiumum frequency possible. Even with perfect ears and the best equipment, there is no audible (and mathematical) difference to be had.

    Everyone who claims otherwise should watch Monty’s explainer videos. I know they are quite old at this point, but everything he explains is still perfectly valid. If that does not convince you, nothing will.


  • It turns out that dynamic range is limited by the audio sampling rate and the human ear can easily detect a far greater range CD audio supports.

    Dynamic range isn’t limited by the sampling rate. It is limited by the resolution, which is 16 bits for the audio CD. With that resolution you get a dynamic range of 96 dB when not using any dithering and even more than that when using dithering. Even with “only” 96 dB that dynamic range is so vast, that there is no practical use of a higher resolution when it comes to playback. I know that the human ear is supposed to be able to handle 130 dB or even more of dynamic range. The thing is, you can only experience such a dynamic range once, afterwards you are deaf. So not much point in such a dynamic range there.

    There are good reasons to use a higher resolution when recording and mixing audio, but for playback and storage of the finished audio 16 bits of resolution is just fine.






  • Ok, that endoflife.date site apparently isn’t quite up-to-date then. But even still, Android 14 was released in October 2023 and as far as I can tell, Fairphone released their Android 14 update only in July 2024. I’m not saying Fairphone’s update policy is terrible or anything. It certainly is better than that of many other vendors, but if you want updates as quickly as possible, you are probably better of with a Pixel phone. Of course repairability is an entirely different matter.





  • Fairphone is actually worse than Google when it comes to updates. Even their flagship phone is still on Android 13. Even the Pixel 6 runs Android 15 at this point and with this news it is guaranteed to get at least Android 17. Google has always been offering 5 years of support for the Pixel 6 and 7 series. What they didn’t promise until this announcement was additional feature/OS upgrades, but when it comes to that they were already ahead of Fairphone.

    When it comes to alternative OSes, Google actually makes it very easy to install them. That’s one reason why GrapheneOS and the likes chose Pixel phones as their primarily supported phones.




  • Linksys WRT54G

    The Linksys WRT54G did not run OpenWrt by default and the original OS does not even remotely resemble OpenWrt. What OpenWrt did use from the original OS was the Broadcom wireless driver because it was closed source (and a similar kernel version, so the driver could be used), since there was no driver in the mainline kernel.

    But to try to answer the question, this device has been designed by the OpenWrt developers to fit their needs (and their users needs). Other routers running some variant of OpenWrt on them by default were designed by companies unrelated to the project. They most likely used OpenWrt because it was convenient to them. Their intentions weren’t usually the same as the OpenWrt team’s (repairability, easy to unbrick, etc.). Not that there is anything wrong with that. I like GL.Inet routers.


  • Actually AMDs mobile parts are pretty good at idle power consumption and so are their desktop APUs. Their normal CPUs, which use the chiplet design are rather poor when it comes to idle power consumption. Intel isn’t really any better when compared to the monolithic parts at idle and Intel CPUs have horrible power consumption under load. Their newest CPUs are better when it comes to efficiency than 13th and 14th gen CPU, bus still don’t match or even exceed AMD.
