Introduction

繼 UPS CP1000AVRLCDa 微開箱 之後，電池過了五、六年開開始無法蓄電，原本不太確定是 UPS 電路的問題或電池的問題，但想了一下以 UPS 相對簡單的模組（電路板 + 電池 + 螢幕），通常會壞掉的應該是電池而不是電路板，因此決定嘗試看看先換電池看續電是否正常（如果換完一樣是壞的就算了）。

Description

在替換電池的選項有滿多種的，受惠於人工智慧，電池可以請 Gemini 先幫忙簡單分析一下差異：

其中 REW 45-12 與 REW 45-12FR 的差別在於其阻燃外殼在極端故障（電池過熱變形）時能提供更高的安全性。

關於放電效能，主要可以分類成兩種，下面段落有請 Gemini 幫忙潤稿：

• 標準型
  • 代表型號： YUASA NP 7-12
  • 特性說明： 專為長時間、小電流的穩定放電設計。雖然續航力紮實，但缺乏瞬間爆發力。若連接電腦主機等高耗能設備，停電瞬間電壓會因無法負荷大電流而「瞬間崩潰」，導致 UPS 提早跳電關機。
  • 最佳用途： 路由器（Router）、數據機、監視器、LED 應急燈等低功耗設備。
• 高率型
  • 代表型號： YUASA REW 系列、CSB HR/HRL 系列
  • 特性說明： 針對 UPS 特性優化，具備極強的高功率輸出能力。鉛板設計讓它能在停電瞬間穩定扛住大電流衝擊，確保電壓平穩不跳脫，讓您有充裕時間存檔。
  • 最佳用途： 電競主機、工作站、NAS 伺服器、或接有多顆螢幕的高耗能環境。

在這次替換電池的選擇中選用的是 REW 45-12FR。

圖片中上方的電池分別是原廠內建的電池型號 DKW12-9.0，下方的電池則是這次用來替換的電池型號 REW45-12FR。

替換方法可以參考巴哈姆特的文章 【心得】「UPS 電池故障，自行更換分享」Cyber Power 碩天 CP1500PFCLCDa，更換方式與文章分享的相同，不過有幾件需要注意的事情：

1. 文章中有提到連接線非常緊（這確實），但沒有到需要出動尖嘴鉗的程度，建議可以用利用手拔下就好。
2. 雖然文章中有提到拆的順序應該沒什麼差，可以的話優先拔負極，但建議還是養成習慣在去電時優先拔負極，裝回去時則反過來優先莊正極。
3. 在替換完畢後建議先讓 UPS 充滿電後再裝上負載設備。

Create a Flask+uWSGI+Nginx Docker Image

In this example, we will create a Docker image for a Flask application using uWSGI and Nginx. The image will be based on the tiangolo/uwsgi-nginx-flask image, which is a popular choice for deploying Flask applications in production.

Create a Private Docker Registry and Push/Pull Docker Images

In this guide, you will:

1. Install Docker on an Ubuntu server
2. Set up a private Docker registry on the Ubuntu server
3. Create a Docker image on Windows and push it to the private registry
4. Pull the image on the Ubuntu server and run it

Create a ASP.NET Core Docker Image

This is a simple demo for creating a Docker image for an ASP.NET Core application.

Before starting, ensure you have the following requirements:

1. Install Docker.

2. Install the .NET SDK.

3. Prepare an ASP.NET Core application. You can create a new ASP.NET Core Web API project using the following command:

   1	$ dotnet new web -n Demo

Introduction

This guide outlines the steps to set up an OpenVPN server on Ubuntu 24.04, including certificate management, server configuration, firewall setup, and client provisioning.

Introduction

After enabling the OpenVPN server on an ASUS router, the exported client.ovpn file may trigger the following error in the OpenVPN client on Android:

1

OpenSSL: error:0A00018E:SSL routines:SSL_CTX_use_certificate:ca md too weak

This issue occurs because the CA certificate uses the SHA1 signature algorithm, which is outdated and considered insecure. Consequently, the OpenVPN client refuses to accept it.

There are two possible solutions:

1. Insecure (Not Recommended): Allow weak CA certificates.
2. Recommended: Renew the CA certificate using a stronger signature algorithm (e.g., SHA256 or higher).

Allowing weak certificates may expose your connection to man-in-the-middle (MITM) attacks or other vulnerabilities.

This guide walks you through the recommended solution.

Introduction

This guide shows you how to set up rsync on a Windows system by leveraging Git Bash from Git for Windows.
rsync is a powerful file synchronization tool commonly used on Linux, but it can also work on Windows with a few manual steps.
No need to install WSL or Cygwin - just follow this lightweight and portable method.

Introduction

This guide shows you through how to mount an external USB disk on an Ubuntu system and then access it from a Windows computer by mapping it as a network drive via SSH.
You don’t need to set up Samba or NFS — just SSH, which is often already available on Linux.

在 Windows 10/11 上透過 Microsoft Store 更新 Samsung Notes (v4.3.181.0) 後，此 App 已經不能在非 Galaxy Book 的電腦上執行。目前有兩種解決方案可以緩解此問題，您可以嘗試其中一種。但請不要將兩種解決方案混用。

FFmpeg is a free and open-source software project consisting of a suite of libraries and programs for handling video, audio, and other multimedia files and streams. At its core is the command-line ffmpeg tool itself, designed for processing video and audio files. It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects, and standards compliance (SMPTE, ITU).
