MBA调整Launchpad每列每行的数量方法

MacBook调整Launchpad 启动台的每一行、和每一列图标的数量,达到调整Launchpad图标大小的目的。

defaults write com.apple.dock springboard-columns -int 12
defaults write com.apple.dock springboard-rows -int 8
defaults write com.apple.dock ResetLaunchPad -bool TRUE
killall Dock

以上每行的含义:
1、调整每一列显示图标数量,9表示每一列显示9个,数字部分可根据个人喜好进行设置。
2、调整多少行显示图标数量,这里我用的是6,数字部分你也可以改成8或其他
3、重置Launchpad
4、重启Dock

JAVA&PYTHON

下面是Java和Python之间一些常见方面的区别总结成表格:

码块 |
| 变量定义 | 需要显式指定变量类型 | 不需要显式指定变量类型,使用动态类型 |
| 方法函数 | 方法必须定义在类中,使用关键字 publicprivate 等修饰符 | 函数可以独立定义,不需要包含在类中,使用关键字 def |
| 类 | 所有代码必须在类中,类是Java程序的基本构建块 | 可以有类,也可以没有类,定义类是可选的 |
| 继承 | 支持单继承,类只能继承一个父类 | 支持单继承和多继承,类可以继承多个父类 |
| 异常处理 | 使用 try-catch-finally 块来捕获和处理异常 | 使用 try-except-finally 块来捕获和处理异常 |
| 包管理 | 使用 Maven、Gradle 等工具管理依赖和构建 | 使用 pip 工具管理依赖和构建 |
| 迭代器 | 使用 for-each 循环遍历集合 | 使用 for-in 循环遍历集合 |
| 面向对象 | 面向对象语言,强调类和对象的概念 | 面向对象语言,但也可以以函数式编程方式使用 |
| 并发 | 支持多线程和并发编程 | 提供多种并发编程方式,包括多线程、协程和异步编程等 |

东北vs北京

东北是家,从05年上大学开始至今18载,累计驻留不足两年。北京不是家,却足足占据我这18载年华的大半时光。
或许,这世界上有两个我,一个在文字里,灵魂在东北,白马春衫慢慢行,另一个我,肉体在北京,蝇营狗苟的都市高楼中意难平。
细细想来,留住我肉体的,其实不是北京,是生活。灵魂向往的也不是东北,却也是生活。

linux-debian init

    sudo su
    passwd root
    useradd appadmin
    passwd appadmin

打开SSH配置文件/etc/ssh/sshd_config,使用root权限进行编辑:

    vim /etc/ssh/sshd_config
 PermitRootLogin no                         //允许root登录      
 PasswordAuthentication yes                 //设置是否使用口令验证
    service sshd reload

**

*

apt install sudo -y

添加你的本地用户到 sudo 组,可以使用 usermod 命令,如下:

usermod -aG sudo linux265

校正日期和时间:
-- 时区列表

    timedatectl list-timezones

-- 修改系统时区为亚洲/上海

    sudo timedatectl set-timezone Asia/Shanghai

-- 查看

    timedatectl

进行系统更新:

Debian install typecho

    tar -zvcf typecho.tar.gz

    wget https://github.com/typecho/typecho/releases/download/ci/typecho.zip

2.解压

    unzip typecho.zip
    tar -zxvf typecho.tar.gz

3.为了防止权限出现问题, 修改全部文件的权限

    chmod 777 -R /var/www/typecho

4.安装PHP及扩展

    sudo apt-get -y install php8.2-sqlite3 php8.2-fpm p
<!--more-->
hp-mbstring php8.2-gd

5.启动php7.4-fpm, 默认监听9200端口

    sudo systemctl start php8.2-fpm
    service php8.2-fpm start

6.检查 PHP-FPM 配置:

打开 PHP-FPM 的配置文件,通常位于 /etc/php/8.2/fpm/pool.d/www.conf 中
确保 listen 配置项与 Nginx 的配置匹配。

/run/php/php8.2-fpm.sock

确保 listen.owner 和 listen.group 配置项与 Nginx 运行的用户和用户组匹配。

打开 Nginx 的虚拟主机配置文件,检查 fastcgi_pass 配置项。

fastcgi_pass unix:/var/run/php-fpm/www.sock;

确保此路径与 PHP-FPM 配置中的 listen 配置项一致。

tar file add passwd

使用tar对文件压缩加密:

  tar -zcvf - pma|openssl des3 -salt -k password | dd of=pma.des3

完成将得到一个pma.des3的打包文件,用你设置的密码替换password。

使用tar对加密文件解压:

  dd if=pma.des3 |openssl des3 -d -k password|tar zxf -

注意:命令最后有”-”,它将释放所有的文件。其中-k password可以不使用,这样执行完命令后会提示你输入密码,加上-k参数表示在程序中自动验证密码。

      /etc/nginx/.htpasswd gz
  • 二、安装typecho

    https://docs.typecho.org/install

    下载php及相关依赖

    sudo apt-get install php7.4 php7.4-sqlite php7.4-fpm php-mbstring php7.4-gd  
  • 安装依赖
    sudo apt install php php-cli php-fpm php-mysql php-json php-opcache php-mbstring php-xml  
  • 启动php服务:查找对应的 PHP-FPM systemd 服务单元文件。在 /lib/systemd/system/ 目录下查找以 php{version}-fpm.service 命名的文件,例如:

        service php7.4-fpm start
  • 下载源码(可以在typecho官网找到)

         wget https://github.com/typecho/typecho/releases/latest/download/typecho.zip

    解压源码

      unzip typecho.zip

    对整个源码目录赋予足够的权限

      chmod -R 777 /home/typecho
  • 配置nginx

      server{
          listen 80;
          server_name ****.xyz;
    
          root /var/www/typecho;
          index index.php;
    
          if (!-e $request_filename) {
              rewrite ^(.*)$ /index.php$1 last; 
          }
    
          location / {
              root html;
              index index.php index.html index.htm;
    
              set $path_info "";
              set $real_script_name $fastcgi_script_name;
              if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
                  set $real_script_name $1;
                  set $path_info $2;
              }
              fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
              fastcgi_param SCRIPT_NAME $real_script_name;
              fastcgi_param PATH_INFO $path_info;
          }
    
          location /admin {
              index index.php;
              try_files $uri $uri/ /admin/index.php?$args;
          }
    
          location ~ .*\.php(\/.*)*$ {
                  include fastcgi.conf;
                  fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
          }
    
          # Typecho static files
          location ~* ^/(usr|admin|themes|plugins)/.*\.(js|css|png|jpg|jpeg|gif|ico|svg)$ {
              expires 24h;
              add_header Cache-Control public;
              access_log off;
    
              try_files $uri $uri/ /index.php?$args;
          }
    
      }

  • linux crontab

    定时任务,自动更新证书和备份文件仅保留一周内的:

         [root@iZj6c69digospl6f2d3s45Z bitwarden-backup]# crontab -l
            21 0 * * * "/root/.acme.sh"/acme.sh --cron --home "/root/.acme.sh" > /dev/null
            0 0 * * * /opt/bitwarden-backup/bw-data-backup.sh >> /opt/bitwarden-backup/backup.log && find /home/appadmin/bitwarden-backup/ -type f -name "bw-data_backup_*" -mtime +7 -exec rm {} \;

    编辑命令:

        crontab -e

    使之生效:
