  • This device attaches to a car’s tailpipe, capturing heat and converting it into usable electricity. The researchers’ innovative system includes a semiconductor made of bismuth-telluride and uses heat exchangers—similar to those found in air conditioners—to capture heat from vehicle exhaust pipelines efficiently.

    Basically, slap Peltier modules on the exhaust pipe. This ain’t gonna do much. We can invent a thousand applications for Peltier modules, until there is a massive technology breakthrough in terms of semi-condutor materials, it’s kinda pointless.

    Reusing heat energy from exhaust is what turbos are doing for 120 years now.

    FOSS driver only, the choices are AMD and Intel. Nvidia is out of the picture.

    Of coursenouveau drivers are still around and under active development, but as far as I know the performance if still very far from reasonable expectations.


  • If you want to bring more people to Linux, preaching is really not a good way to do that. We are not a religion, we are not a cult. We are an enthousiastic bunch or nerds :)

    Avoid behind judgemental of people that use Windows, Mac or other proprietary software. Do not talk about Linux in length when it was not solicited.

    Instead, you can show how enthusiastic you are about all the cool things you are doing with your computer that happens to be running Linux!

    When people around you, do make the choice to switch, of their own will, then offer your help with all the patience and understanding you have.

    All the best 🐧🐧🐧


  • I have a good experience with the NVidia shield TV (2017). Jellyfin app work great without tinkering and HEVC deciding is supported by this device, minimizing the need of transcoding.

    The experience outside of Jellyfin needs some work though, to get an ad-free experience. Once Projectivy Launcher and Smart Tube installed and configured, I am fully satisfied.

    I haven’t played too much with Raspberry, I think HW decoding is still a point of pain.


  • Take the time to properly understand Linux file ownership and permission. Permission will be the cause of many issues you will encounter in you self-hosting journey on Linux. Make sure you know the basics of chmod (change permission) and chown (change ownership), Linux users and groups. This will save you some head-scratching, but don’t worry, you will learn by doing !

    Remember that, if you setup everything right, especially with docker, running as root / with sudo is not required for any of the services you may want to run.



  • I use 2 VPN with my setup:

    1. The private one, hosted on a VPS (OVHcloud). I set it up my self. It’s a bit of work, as you need to take care of properly setting up firewall and reasonably security this server as it is directly facing the Internet. OVH provids some good guides on their website and you can find other resources. You can rent the lowest tire VPS and deploy Debian and Wireguard and you’re all set ! This VPN is for connecting to my NAS at home from outside, and also for secure Internet browsing from public WiFi. This is my own VPN for me and myself (plus my family to a lesser extent).
    2. The one for Torrenting exclusively Linux ISO of course. This one is a Nord on subscription, and the benefits is not really privacy IMO but rather to be drown into the traffic of thousands of other users.


  • It no longer make sense to depend on the good while of the phone manufacturers to keep maintaining the OS for our smartphones. We should move towards a system more similar to PCs where hardware and OS are broadly intercompatible and can be exchanged and upgrade seamlessly.

    If I have the ability to replace the battery, I don’t see why my 2022 smartphone would become obsolete in 2032, other than arbitrary SW end of life. Just like my 12yo laptop works perfectly fine despite the battery being weak, which I already replaced in the past and still could today !
