通常情况下，国内使用PIP可以参考Pypi国内镜像设置来设置国内镜像以加快安装速度。 但有的pip软件包国内镜像出于各种考虑并未收录，因此就得使用Pipy.org的官方源安装，在网络状况不理想的情况下，我们可以使用设置代理来加速安装过程。 例如，我们已经获得了代理服务的配置，如下： http://127.0.0.1:2080 socks://127.0.0.1:2080 如果是linux系统，可以使用系统自有的环境变量http_proxy、https_proxy $ export HTTP_PROXY=http://127.0.0.1:2080 $ export HTTPS_PROXY=http://127.0.0.1:2080 使用pip自带选项--proxy来使用代理 $ pip install --proxy=http://127.0.0.1:2080 jupyter 使用pip配置文件pip.conf或pip.ini来设置代理 Windows下是pip.ini，linux下是~/.pip/pip.conf或/etc/pip.conf [global] proxy = http://127.0.0.1:2080

tar是一款经典的打包程序，用于将多个文件进行打包存储，tar设计之初就是为了方便将文件存储与磁带上，tar这个名字就是由此而来，表示Tape Archiver。 tar可以方便的对多个文件进行打包处理，也可对已经打包好的文件(.tar文件)进行查看增补等操作。 人们通常在打包完成后，还会进行压缩操作，使用tar我们可以方便的将打包压缩两个操作合二为一，一次性输出压缩后的结果。 tar最常用的四个参数 适用tar时，后面的参数可以分别写，也可以写在一起，即tar -cf name和tar -c -f=name效果相同。 创建新的tar包 -c 或者 --create 查看tar包内容 -t 或者 --list 从tar包提取内容 -x 或者 --extract 指定tar文件名 -f archive-name 或者 --file=archive-name 显示操作详情 -v 或者 --verbose tar打包常用操作实例 tar打包文件 $tar -cf t.tar document.docx sheets.xlsx text.txt tar查看内容 $ tar -tf t.tar document.docx sheets.xlsx text.txt tar提取内容 ## 提取t.tar包内容 tar -xf t.tar ## 提取t.tar包中指定的文件text.txt，注意这里必须用参数全名，不能用简写 tar --extract --file=t.tar text.txt tar打包压缩 tar可以在打包时同时条用压缩程序压缩文档，支持多种压缩程序，如：gzip, bzip2, lzip, lzma, lzop, zstd, xz和compress。 ...

Bluesky是一个去中心化的分散式社交系统，与 Mastodon (长毛象) 相似，不过Bluesky 自行开发的AT Protocol协议无法与 Mastodon 的 ActivityPub 互通。 同样是可自行架设的社交平台，比较特别的是 Bluesky 并不像 Mastodon 一样包含了前端网页(web)，它只有提供API功能，需要专门的前端来进行登录管理。 自行部署的Bluesky服务器被称为个人数据服务器 (Personal Data Server, PDS)，使用者可以在 bsky.app 网页版或 iOS、Android客户端中登录自行部署的pds服务。 pds推荐主机配置 操作系统 Ubuntu 22.04 内存 (RAM) 1 GB CPU核心 1 CPU构架 amd64, arm64 硬盘 20 GB SSD 可服务账号数 20 VPS部署PDS实例 域名设置 以pds.p9.pub为例，服务器IP为195.192.118.6 将pds.p9.pub和*.pds.p9.pub的A记录修改为195.192.118.6 安装pds 通过以下命令下载安装脚本 wget https://raw.githubusercontent.com/bluesky-social/pds/main/installer.sh 然后运行bash ./installer.sh来开始安装 bash ./installer.sh * Detected supported distribution Debian 12 --------------------------------------- Add DNS Record for Public IP --------------------------------------- From your DNS provider's control panel, create the required DNS record with the value of your server's public IP address. + Any DNS name that can be resolved on the public internet will work. + Replace example.com below with any valid domain name you control. + A TTL of 600 seconds (10 minutes) is recommended.
