### Pellaeon 分享
- Zenmonitor
- 看 CPU 目前的功率
- MSR register
- `tlp-stat -b`
- 閒置時, 7~10 瓦 (22.10)
- kernel 5.15 + AMD p state back port + powersave governamer 沒有效
- 換到 22.10 之後,這個狀況有改善
- AMD embedded controller 是跟著 BIOS 更新, via fwupd.
- 產品溫控有可能是由主板嵌入式控制器(而非 kernel)決定,有可能無法由使用者自由控制
- Linux 上顯示中文字型的研究、Kubuntu 的 bug (56-kubuntu-noto.conf)
- https://nyllep.wordpress.com/2022/11/30/linux-cjkfont/
- 打開 hinting 讓字的筆劃會比較清楚
- 上述的 `56-kubuntu-noto.conf` 會強制打開 hinting
#### Rex's investigation

### 林博仁 - Image Scan for Linux! V2 Snap 軟體包開發歷程分享

#### Ref
* If someone is till interested in how to work around the problem of a Snap not being able to install UDEV rules into the system, I have found a solution, as I need UDEV for my printing-related Snaps. - https://forum.snapcraft.io/t/how-to-add-or-workaround-a-udev-rule/12829/8
### Fourdollars - Hardware enablement
* 使用 modalias 識別認證硬體
* 目前 Linux 廠商只有 Canonical 有在大量地對新上市電腦硬體進行 enablement
* 一個產品可能有多個 SKU 有不同的硬體配置,沒有跟廠商配合難以透過社群支援
* 在一個 Ubuntu 釋出版本認證過的硬體不保證在後續的釋出版本(LTS+1)會完全相容(資源限制)
