If you have git and a GitHub account, then you can set it up in a couple of minutes with these 10 simple steps:

Go to your GitHub account and create a new repository for your Obsidian vault

Copy the SSH URL of the repo (e.g: git@github.com:Your_resp/notes.git)

Download Obsidian Git from Community Plugins

After installing and enabling the plugin:

Cmd+P

Execute Git: Initialize a new repo (this will create the .git folder in your vault)

Go to a terminal, cd into your Obsidian vault and add a new origin to your local repo (e.g. git remote add origin git@github.com:Your_resp/notes.git)

Commit all the changes:

Cmd+P

Execute Git: Commit all changes (this will commit all your notes in your local repo)

Go to your terminal again and push the changes to the remote repo git push -u origin main (you need to do this just once to create the branch in the remote repo).

From now on, whenever you want to backup your notes, just:

Cmd+P

Execute: Git: Commit-and-sync

Profit!

vscode+MASM/TASM+DOSbox

Pre: vscode

  1. vscode plugin

    MASM/TASM

  2. brew install DOSBox

  3. VSCode DOSBox的插件设置

Vscode-dosbox > command: Dosbox
第一行的dosbox改成open -a dosbox --args

不要直接使用code runner运行。要在当前文件编辑界面 右键点DOS框中的运行

Here is a thrilling scene, featuring two teams racing on dragon boats with crowds of people cheering on the bridge. At the corner of the picture, an old woman is holding her husband’s hand, smiling with satisfaction, expressing her happiness seeing the dragon boat race of their village is getting more and more popular.

The idea of the artist lurking behind the caricature can be perceived as an appreciation of the boosting tourism based on traditional Chinese festival in villages. A majority of relevant departments tend to develop blinking forms of activities while overlooking the very essence of them, leading to the result that commercial interest is overstated and the beauty of conventions are forgotten. This tendency may seem innocuous in the short term, risks erasing the sense of belonging in dwellers’ hearts and jeopardizing the real interactions between people and the past in a larger sense. To address the obstacles met in advancing a county requires a shift in mindset-focusing on the daily lives of the public and the thriving of cultural activities. The responsibility urges city authorities to fulfill their role through leading the trend, establishing proper environment for citizens to enjoy such festivals.

With collective commitment in promoting traditional affairs, we can aspire to see more villages or cities to have significant changes and win both ecologically and admirably.

问题背景

一体机从购入（2017年中）至2025年1月使用，打印，扫描一切正常。2025年2月出现打印速度很慢，打印测试页一张大约需要5min左右。扫描文件正常，包括传输速度

一台HP-M126nw一体机。一台小米路由器4a千兆版

连接方式

节点：打印机、路由器、终端设备（PC/手机）

打印机通过2.4Ghz Wi-Fi连接路由器，其他终端设备（PC，手机）通过2.4Ghz Wi-Fi和5Ghz Wi-Fi连接路由器

路由器购入于2018年中，打印机购入于2017年中

解决方案

路由器换新

尝试过的解决方案【以下于本例中均无效】

  1. 重启Print Spooler

  2. 重新安装驱动

  3. 将驱动替换为PCL

  4. 将驱动替换为aserjet p1108驱动

  5. 打印机重置

  6. 因为电脑是通过网卡启动，所以切换系统比较自由。一开始是以为Windows 11的问题，而且HP社区也有相关的情况，所以当时就退回了当时安装的Windows 10, 发现Windows 10下也有问题，然后又退回Windows 7，Windows 7下问题依旧。OS X测试了：OS X10.9、macOS16。手机无线打印测试了AirPrint

  7. 关于有线打印，由于打印机距离电脑过于远，没有尝试
