使用MailCatcher作为开发环境邮件服务器

MailCatcher 运行一个超级简单的 SMTP 服务器，它可以捕获发送到它的任何消息并在 web 界面中显示。

运行 mailcatcher，将你最喜欢的应用程序设置为 smtp://127.0.0.1:1025，而不是默认的 SMTP 服务器，然后检查 http://127.0.0.1:1080，查看到目前为止的邮件。

ubuntu安装MailCatcher

sudo apt install ruby ruby-dev libsqlite3-dev build-essential
sudo gem install mailcatcher

运行

默认运行即可，更多参数如下

mailcatcher -h
Usage: mailcatcher [options]
        --ip IP                      Set the ip address of both servers
        --smtp-ip IP                 Set the ip address of the smtp server

Cmder + Windows Terminal + PhpStrom/PyCharm/IDEA

发表评论

Cmder是一个可用于linux的便携式控制台虚拟器，可以让你在windows下使用linux命令。

Windows Terminal是Windows 10的控制台管理界面。

IDEA是广大开发人员的最爱。

本文介绍如何将Cmder整合到Windows Terminal和IDEA。

file

安装Cmder

可以去 https://cmder.net/ 下载最新的压缩文件，解压后点击Cmder.exe即可使用。如果已经安装了git for windows下载mini版本就可以了，否则可以下载包含git的full版本。

设置系统环境变量

以下d:\tools\Cmder是Cmder解压目录

CMDER_ROOT = d:\tools\Cmder

配置 Windows Terminal

生成guid

进入Power shell，输入New-Guid

PS C:\Users\Administrator> New-Guid

Guid
----
092f8948-9ea5-4928-bea7-a1f71938e717

修改 Windows Terminal 配置文件

点击Windows Terminal的下拉菜单，选择“配置”，会打开它的配置文件

增加

{
  "guid": "{092f8948-9ea5-4928-bea7-a1f71938e717}",
  "name": "Cmder",
  "commandline": "cmd.exe /k %CMDER_ROOT%\\vendor\\init.bat",
  "startingDirectory": "%USERPROFILE%",
  "icon": "%CMDER_ROOT%\\icons\\cmder.ico",
  "background": "#2e3436",
  "padding": "15",
  "fontFace": "Cascadia Code",
  "fontSize": 10
}

然后修改

"defaultProfile": "Cmder",

Windows Terminal 使用效果

点击Windows Terminal的加号，查看效果

file

配置 PhpStorm/IDEA/PyCharm

配置 PhpStorm

打开 PhpStrom 的设置，找到 Tools 下的 terminal 修改 Shell path 为 "cmd" /k ""%CMDER_ROOT%\vendor\init.bat""

file

PhpStrom 配置后效果

以下脚本会先找到正在运行的程序和服务，停止并删除服务，然后杀掉正在运行的程序进程

    ;检查服务是否存在
    SimpleSC::ExistsService  "${SVCHOST_EXE_NAME}"
    Pop $0
    ;停止并删除服务
    ${If} $0 == 0
        DetailPrint "停止正在运行的打印服务"

JSON、BSON及Protocol Buffer比较

发表评论

他们核心区别在于，bson在json基础上增加了数据日期、文档类型，并支持二进制传输；而protocol buffer则对传输数据和结构定义进行了分离。一般来说与浏览器通信通常使用json，如果需要跨语言通信，且考虑效率，则可以采用protocol buffer。

JSON

特点：

文本存储和传输，结构与数据一体，肉眼可识别

优点：

通用性好，各种语言都支持；
可用于存储

缺点：

采用文本传输，占用体积大，传输性能差
序列化，反序列化性能较差
不支持二进制，日期等数据类型

Bson

特点：

采用二进制传输，结构与数据一体

优点：

在json基础上增加二进制和日期等格式；
传输性能较好
序列化，反序列化性能较好

缺点：

多语言支持一般
传输数据与结构定义仍然在一体

Protocol Buffer

特点：

结构定义与传输数据分离，只传输二进制数据

优点：

用protoc工具可以根据proto文件生成各种语言对应代码
字段被编号，新添加的字段不影响老结构，解决了向后兼容问题。
二进制无结构消息，效率高，性能高。

缺点：

二进制格式，可读性差（抓包dump后的数据很难看懂）
默认不具备动态特性

NSIS递归添加和删除子目录及文件

NSIS打包比较配置文件手动编辑起来非常麻烦，使用HM NIS EDIT向导的话就容易多了。

  File /r "bin\Release\*.*"

  RMDir /r "$INSTDIR"

ubuntu-wsl2-systemd-script（适用ubuntu）

sudo apt install git
git clone https://github.com/DamionGans/ubuntu-wsl2-systemd-script.git
cd ubuntu-wsl2-systemd-script/
bash ubuntu-wsl2-systemd-script.sh

genie(适用arch/manjaro/centos等)

yay -S genie-systemd

ubuntu使用国内源

sudo sed -i 's/archive.ubuntu.com/mirrors.ustc.edu.cn/g' /etc/apt/sources.list
sudo apt update -y

启用适用于 Linux 的 Windows 子系统

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

更新到 WSL 2

要求

对于 x64 系统：版本 1903 或更高版本，采用内部版本 18362 或更高版本。
对于 ARM64 系统：版本 2004 或更高版本，采用内部版本 19041 或更高版本。
低于 18362 的版本不支持 WSL 2。使用 Windows Update 助手更新 Windows 版本。

若要检查 Windows 版本及内部版本号，选择 Windows 徽标键 + R，然后键入“winver”，选择“确定”。（或者在 Windows 命令提示符下输入 ver 命令）。更新到“设置”菜单中的最新 Windows 版本。

启用虚拟机功能

dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

下载 Linux 内核更新包

适用于 x64 计算机的 WSL2 Linux 内核更新包

将 WSL 2 设置为默认版本

　下载msys2

在中国科学技术大学镜像站点http://mirrors.ustc.edu.cn/msys2/distrib/下载最新版32(i686)/64(x86_64)位系统msys2

下载后安装

修改软件源

msys2采用pacman管理软件包，修改pacman的软件源提高下载速度

pacman的配置
编辑 /etc/pacman.d/mirrorlist.mingw32 ，在文件开头添加：

Server = http://mirrors.ustc.edu.cn/msys2/mingw/i686/
Server = https://mirrors.tuna.tsinghua.edu.cn/msys2/mingw/i686/
Server = http://mirror.bit.edu.cn/msys2/mingw/i686/
Server = https://mirrors.sjtug.sjtu.edu.cn/msys2/mingw/i686/

编辑 /etc/pacman.d/mirrorlist.mingw64 ，在文件开头添加

Server = http://mirrors.ustc.edu.cn/msys2/mingw/x86_64/
Server = https://mirrors.tuna.tsinghua.edu.cn/msys2/mingw/x86_64/
Server = http://mirror.bit.edu.cn/msys2/mingw/x86_64/
Server = https://mirrors.sjtug.sjtu.edu.cn/msys2/mingw/x86_64/

编辑 /etc/pacman.d/mirrorlist.msys ，在文件开头添加

GlitchTip – 开源的Sentry API兼容的错误跟踪系统

发表评论

GlitchTip is an open source, Sentry API compatible error tracking platform. It is a partial fork/partial reimplementation of Sentry’s open source codebase before it went proprietary. Its goals are to be a modern, easy-to-develop error tracking platform that respects your freedom to use it any way you wish. Some differences include:

A modern development environment with Python 3 and Django 3.1.
Simplicity over features. We use Postgres to store error data. Our code base is a fraction of the size of Sentry and looks like a typical Django app. We leverage existing open source Django ecosystem apps whenever possible.
Respects your privacy. No massive JS bundles. No invasive tracking. No third party spying. Even our marketing site runs Matomo and respects Do Not Track. GlitchTip will never report home. We will never know if you run it yourself.
Commitment to open source. We use open source tools like GitLab whenever possible. With our MIT license, you can use it for anything you’d like and even sell it. We believe in competition and hope you make GlitchTip even better.

Project status: Stable. Open an issue and say hello if you’d like to help. We are able to process basic error requests from the open source Sentry client tools. More features are on the way.
