簡單說一句就是，除了操控流暢度以度，其他都沒比較好，照相我就不比較了，就讓專業的去比

Stable Diffusion webui is a web service based on Gradio library for Stable Diffusion. The installation process can automatically set up the environment and install Stable Diffusion, which can save a lot of time. However, it requires an NVIDIA or AMD GPU to install it. If you want to install Stable Diffusion WebUI without a GPU, some modifications are necessary.
Using a CPU to run Stable Diffusion can be painful, so this article is just for fun.
Platform is Ampere Altra Mt. Collins system with 2 Ampere Altra CPU, total 160 cores.
OS: ubuntu 22.04.02 LTS
Seems Stable Diffustion webui needs python 3.10, so, ubuntu 22.04 is good choice.

有時候人生就是不能亂買東西，一步錯步步錯，然後就弄了這個出來，當然不是圖中大螢幕的屋內屋外溫濕度狀況，而是左上角小小的溫度預測
至於怎麼來的，一切都要從邪惡的阿媽爽60元免運說起，因為60元免運，有時候就會將有些小東西放到購物車內，因為有時候即使加了稅金，從美亞（美國亞馬遜Amazon）網站買東西還比淘寶買便宜，更不要說很多東西只有美亞有，這時候小東西湊60元免運頗方便的
原來是我有二張 Arduino 的板子，本來也只是接來做溫度偵測，也沒有什麼用，想說接個小螢幕顯示一下天氣預報，但是這東西又不是很必要，就想想而已，就隨便找了一個看起來順眼的 SPI LCD 和 OLED （想說比較省電）就放到購物車了，上個月美國很多東西都特價，兩雙鞋子才 30 元美金，這塊 OLED 好像也才 15 上下，就被拿來湊運費了，沒想到我手上並沒有東西可以接

地攤貨的品質，百貨公司 Hedgram/Michael Kors/Coach 專櫃的價格（不是 outlet 價哦）
Porter Internaltion 簡單說就是台灣的商標蟑螂，雖然說已經和解了，但是揮不去本質就是蟑螂的本性
2001年的時候，尚立國際卻搶先YOSHIDA & CO., LTD一步，以「PORTER」的名義在全球各地進行商標註冊（只有日本及香港除外，因為YOSHIDA & CO., LTD當時已於這兩個地區註冊了），並正式定名為PORTER INTERNATIONAL，對此當年YOSHIDA & CO極度不滿，更與尚立國際展開歷時數年的專利訴訟

Due to CentOS website document cannot provide a simple instruction to build CentOS 8 stream with some easy steps. So, I make a note to record these procedures about how to build it.
Detail description and instruction, please refer to CentOS document, but if you have read the document and still don’t know how to do that, it can follow my instruction to build the kernel from CentOS 8 kernel source.

It’s a strange problem, after login kubuntu/ubuntu system, after a while, the mouse click won’t work anymore suddenly. but it still can move. original post is for ubuntu 18.04, but it’s also work on my ubuntu 22.04
How to solve it temporary ? reload the psmouse driver
sudo modprobe -r psmouse
Suppose the ACPI driver or UEFI cause this issue, but not easy to find it out.
