  6. I've just seen a IT video saying "I always leave the background as default."
    I always change the background & colours to my favourites.

    It has a side-benefit: occasionally I have seen a malicious pop-up window trying to get me to do something. It stands out because it's not in my colours

  9. Set a static IP on Linux:
    nmcli con mod "connection-name" ipv4.addresses 192.168.1.100/24
    nmcli con mod "connection-name" ipv4.gateway 192.168.1.1
    nmcli con mod "connection-name" ipv4.method manual
    nmcli con up "connection-name"

    Because "it gets an IP from DHCP" is fine...until it isn't.

  39. #TechTip: If you have an Android Phone with Android 14 or later you probably have a pretty decent USB webcam on your hand. If you connect your phone via USB to a PC you get a popup on your phone and when you tap on it you can select "Webcam" and your phone will be available as a normal USB camera to your system. I confirmed it working on Windows and Linux and depending on the camera in your phone you get a very good picture.

  44. Giải pháp nghe nhạc cho phần cứng yếu: Jellyfin hay Navidrome?

    Một người dùng chạy OMV trên Thin Client cũ (AMD GX-217GA, 8GB RAM) gặp tình trạng lag nghiêm trọng (trễ tới 1 phút khi chuyển bài) khi dùng Jellyfin làm máy chủ nhạc qua ứng dụng Symfonium.

    Với cấu hình yếu, Jellyfin thường quá tải. Navidrome được đề xuất như một lựa chọn thay thế tối ưu hơn: nhẹ, nhanh và quản lý thư viện nhạc lớn tốt hơn hẳn trên các thiết bị cấu hình thấp.
