    Fedora Silverblue 如何新增硬碟到 Btrfs 陣列

    我目前的主力電腦是一台 2020 年購入的 System76 的 Lemur Pro (lemp9),前陣子無線網路卡掛點,自己換了新的 Intel AX210 模組。 今天有感於最初設定的規格 500 GB 的 SSD 儲存空間有點不夠用了,想要加裝新的 SSD 來擴增容量。lemp9 內部有兩個 M.2 NVMe 的空間,所以我還有一個空位可以用。

    Gallery3D is the gallery application released with Éclair, contributed by Cooliris. This application heavily uses OpenGL to render the scenes. It looks great on Nexus One. But 0xdroid does not yet support hardware accelerated 3D graphics and rely on libagl to rasterize the 3D graph.
