生成的 61 个琴键模型，高度是条抛物线
\n\n然后算下来打印时间大概要 91.5h，如果 24h 无间断打印的话要 3.8 天... 今天发现 Cura 的一个实验性功能可以让多个模型在同一个平台上顺序打印，很灵车但是好想试试，如果可以的话睡觉的时候也能让打印机工作了（打印机加油！\n\n真正打印的时候才发现这个打印机有好多问题，果然不应该相信半价全新... 首先是自动调平不工作，而且因为这款 \"Smart\" 打印机的受众是富家小孩，设计师去掉了需要耐心的手动调平旋钮。研究了一下发现是固件逻辑每次回零都会把调平 Mesh 关掉，也就是说自动调平完全没有用到。解决方案就是在 GCode 开始段回零之后加一句 `M420 S1` 重新启用调平... 创想啊你完全不测试你的代码么 (╯’ – ‘)╯︵ ┻━┻\n\n
自动调平 Mesh 可视化（好歪！）
\n\n然后看到印床底下有一颗孤零零的螺丝 ;-;;; 估计要拆下整个 y 轴才能取出来，好麻烦啊，不过有一点点小风险也没关系？\n\n
卡在床下面的螺丝
\n\n今天下午和聊聊去拼装模型爱好者的店买了喷漆罐，打算喷成 V7530BCF 那样的金属黑色。给 PLA 喷漆也很讲究呢，需要先喷 Primer，喷漆，再喷保护层，还要一个通风柜... 原本想在厕所开上换气喷，但是看到成分里含有机溶剂，只能等天暖在外面喷了呜呜。\n\n晚上复用器芯片到了，因为 D1 ESP32 控制板只有六个模拟输入，用来接 61 个琴键肯定不够，所以就改成了用四个 16 输入的复用器去读四个输入啦。去焊了四片芯片上的 96 个引脚。开始焊之前觉得 96 个引脚好多好可怕，但是熟练之后发现其实可以很快的，焊最后一个芯片的 24 根引脚只花了两分钟，离成为一个合格的工程师更近了！零件还缺 60 个 1MΩ 电阻和 60 个二极管和一些转接头就收集齐了！"}, {"id": 7, "title": "Snowy World", "subtitle": "一个 telnet 协议的 ASCII 动画", "file": "content/posts/2023-03-09 Telnet Game.md", "tags": [], "date": "2023-03-09T00:00:00", "url_name": "2023-03-09-Telnet-Game", "content": "\n\n写了一个 telnet 协议的 ascii 动画！（花了一整天又没什么用，但是好好玩ww\n\n用指令 `telnet hydev.org` 连接哦。记得用一个好用一点的终端，比如 kitty / iTerm2\n\n

\n\n昨天和鱼塔闲聊，从某紫底绿字网页聊到复古终端又聊到 telnet 论坛。这是我第一次见到 telnet 协议的论坛哇，连进 ptt 和水木论坛转了转，完全被五颜六色的字符画和各种小彩蛋吸引住了 qwq 决定我也写一个简单 ascii 动画放进我的小小角落...\n\n...然后就这样花掉了一整天 🌚\n\n刚开始用 python 两个小时写好了 telnet 监听、雪花、字符画、移动，简简单单地一层一层字符打上去，但是这样会让图层闪来闪去。然后改成了存 framebuffer 2d 矩阵，先把不同图层叠到缓存里再统一渲成一层命令行能懂的控制符，但是 py 矩阵遍历真的好慢好慢，用上 numpy 也依然非常慢，渲染一帧要 42ms。好像这个问题并没有解... 用 numba JIT 把遍历函数编译成二进制也只优化到了 16ms。无奈啊，可能方便的语言就是跑不快，借这个契机开始学 rust 了！\n\n
\n \n Python 渲染日志，一圈需要 45ms\n
\n\nrust 确实好不方便，因为不能有全局变量，用 struct + impl 强行模拟了 OOP 的对象，把全局全都写在 struct Main 里面 🌚。但是有时候又不能当作对象，遇到了比如可变指针借用的问题，把常量和变量分开存解决了，还有生命周期什么的，总之是好多写完了也没太学懂的概念。昨天折腾到凌晨五点 rua 完了，没想到同一个 2d 数组遍历只是用 rust 重写就只占用 0.12ms 了哇，350 倍啊 350 倍！\n(╯’ – ‘)╯︵ ┻━┻\n\n~~就此立 flag，以后新坑绝对不会再碰 python 了~~。明明同样是 O(n * m) 的代码居然会差这么多... 现实中优化算法常量也很重要呢\n\n
\n \n Rust 可变 &self 指针借用的报错\n
\n\n接下来想要把写完的命令行程序接到 telnet 协议上，可是 rust 没有做好的 telnet 服务器库，怎么办呢？先是试着用 tokio 手搓一个协议库，发现没办法读未缓存的原始键盘事件，去 SO 问了。之后尝试调用 c 的 libtelnet 库，跑起来到处报 SIGSEGV 呜呜呜。最后还是直接用 py 的代码开子进程做了一个中继，收到客户端的输入转发给 rust，收到 rust 的输出再转发给客户端... 意外地效果还不错。\n\n写完装进 docker 里面部署上去啦。花了一整天，但是学到了 rust，动画的效果也不错，总之很开心。写着写着有点想用这个框架写一个小游戏... 但是不太会游戏设计呢，再想想。"}, {"id": 6, "title": "用校园网搭建服务器！", "subtitle": "在宿舍折腾网络的一篇记录w", "tags": ["技术"], "category": "技术", "file": "content/posts/2022-01-30 Router.md", "date": "2022-01-30T00:00:00", "url_name": "2022-01-30-Router", "content": "欢迎欢迎！我是 UofT 的大一新生，这是我在宿舍折腾网络的一篇记录w\n\n## 1. 搭建 FRP 实现内网穿透\n \n\n\n## 2. OpenWRT 中继学校 WPA-EAP 网络实现远程重启\n\n搭建好内网穿透之后又遇到了新的问题——因为台式机服务器装的黑苹果配置不是很稳定，它有时候会整个屏幕绿掉，必须强制重启才行，应该是 kernel panic 吧。我不在宿舍的时候回宿舍重启又太麻烦了，如果可以远程重启...\n\n想起来之前摸鱼的时候看到向日葵有做过远程重启的设备，所以就去查了下，结果发现就只是一个智能插座，在主板上配置好插电自动开机就好啦。但是这又有一个问题——宿舍里所有的网络，无论是 UofT Wifi 还是 eduroam 还是有线以太网，都需要 WPA/WPA2/WPA3-Enterprise EAP PEAP MSCHAPv2 用户名+密码验证... 可是智能插座只支持简单的 WPA-PSK 密码验证。所以就需要一个可以连上外网、又可以开 WPA-PSK WiFi 的无线路由器了。\n\n刚开始，我想过几个不同的方案：\n\n### a. 用手机连 Wifi 开热点（失败）\n\n之前无意间发现了我的 Mi Mix2S (Android 11 EvolutionX) 可以边连 Wifi 边开热点，不知道是怎样实现的。所以我想，如果用旧的华为 Mate8 这样一边连着学校的 PEAP 一边开热点就可以了。但是开机之后，我发现 Mate8 的原生系统 Android 8 EMUI 8.0 并不支持同时连 Wifi 开热点。我听说用 VPN Hotspot 可以实现无线中继，下载试了下却发现没有 Root 就不能改 SSID 和密码，每次开的 SSID 和密码都是随机的。所以花了超级多精力解锁 BootLoader、刷 Magisk、然后发现 Root 之后也不能改无线中继的 SSID 和密码... 改完之后重开中继的 SSID 还是 DIRECT-{随机}-HUAWEI, 密码还是八位随机字符。不过还是试了下用智能插座连这个无限中继，只能赌无线中继不会重启、不会关机、不会被电源管理杀掉... \n\n结果是，在台式死机之前智能插座就先下线了，回宿舍看了一眼发现手机不知道为什么重启进 Recovery 了。失败失败（\n\n### b. 用手机连数据卡开热点（太贵了）\n\n然后想到如果可以再买一张手机卡只用来开热点就解决了嘛，但是发现这边不像国内那样 ￥10/mo 就能买一张卡，这边最便宜的流量卡要 CA$15/mo，换算出来要 ￥75/mo 了，够买一个路由器了（\n\n### c. 用路由器中继\n\n然后就是现在的解决方案啦，用路由器中继学校的 PEAP。首先要做的是买一个路由器，可是这边新的路由器也真的很贵，亚马逊上最便宜的 TP-Link AC750 要 $35 = ￥175... 所以去二手市场逛了逛，很幸运的看到了附近有人 $10 出路由器，一个 Netis WF2780 和一个小米路由 R4。\n\n首先试了 WF2780，但是它好像没接好 WAN 就完全不能用的样子，SYS 灯一直在闪，网线连上电脑也没办法获取到 IP，手动分配 IP 到 192.168.1.2 也进不去管理页面。可能是坏了吧，也可能这个路由器本来就是这样？不懂，下一个（\n\n然后试了 R4，可是用小米官方的固件，无限桥接模式并不能连上 PEAP 验证的 UofT Wifi 或者 eduroam，有线桥接模式把 WAN 口接上也提示识别错误。所以只能试试 OpenWRT 啦。\n\n### 1. 给小米路由 R4 刷 OpenWRT\n\n这里我跟了 https://www.wyr.me/post/619 这个教程，很轻松地就刷好了！\n\n在电脑上要做的事情：\n\n1. 网线连上路由器，登录管理后台（我是 http://192.168.31.1)\n2. 复制管理后台登录之后 URL 里面的 stok 参数\n3. 执行以下指令，输入路由器的 IP 和刚才复制的 stok\n\n```sh\ngit clone https://github.com/acecilia/OpenWRTInvasion\ncd OpenWRTInvasion\npip3 install -r requirements.txt\npython3 remote_command_execution_vulnerability.py\n```\n\n然后就有 ssh 啦！接下来用了这个固件：https://github.com/ioiotor/mir4-ss，下载 [openwrt-ramips-mt7621-xiaomi_mir4-squashfs-kernel1.bin](https://github.com/ioiotor/mir4-ss/releases/download/V19.07.4/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-kernel1.bin) 和 [openwrt-ramips-mt7621-xiaomi_mir4-squashfs-rootfs0.bin](https://github.com/ioiotor/mir4-ss/releases/download/V19.07.4/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-rootfs0.bin)\n\n4. 在电脑上执行以下指令：\n\n```sh\nmkdir temp\ncd temp\nwget https://github.com/ioiotor/mir4-ss/releases/download/V19.07.4/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-kernel1.bin\nwget https://github.com/ioiotor/mir4-ss/releases/download/V19.07.4/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-rootfs0.bin\npython3 -m http.server\n```\n\n5. 登录进 SSH Shell 之后在路由器上执行指令：\n\n```sh\ncd /tmp\nwget http://{电脑 IP 地址}/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-kernel1.bin\nwget http://{电脑 IP 地址}/openwrt-ramips-mt7621-xiaomi_mir4-squashfs-rootfs0.bin\nmtd write openwrt-ramips-mt7621-xiaomi_mir4-squashfs-kernel1.bin kernel1\nmtd write openwrt-ramips-mt7621-xiaomi_mir4-squashfs-rootfs0.bin rootfs0\nnvram set flag_try_sys1_failed=1\nnvram commit\nreboot\n```\n\n然后就好啦，重启之后就是 OpenWRT 了（虽然默认没有开 WLAN，所以只能网线连到路由器）\n\n### 2. OpenWRT 连接到 PEAP 网络\n\n登录上管理页面，改完管理密码之后，我试了直接把 wlan0 改成 client mode 去连学校的网，但是发现这里也只支持密码验证的 WPA-PSK 而不支持用户名+密码的 WPA-EAP。然后查了一下发现只要把预装的 wpad-basic 换成完整的 wpa-cli + wpa-supplicant + hostapd 就可以了。但是还有一个问题就是我的路由器现在没有网，所以不能在线安装软件包。我的解决方案是用电脑先连上学校的 WIFI，再把电脑的网线连到路由器的 LAN 口上，然后在电脑上开桥接模式路由器就有网了！\n\n之后，ssh 进路由器，执行以下指令：\n\n```sh\nopkg update\nopkg remove wpad-basic\nopkg install wpa-cli wpa-supplicant hostapd nano\nreboot\n```\n\n等重启好之后，管理页面里面 Wireless Security 那一栏的验证方式里面就有 WPA2-EAP 了！接下来把学校的验证信息填进去，然后保存就连上啦！UofT 的配置如下：\n\n```txt\nEncryption : WPA2-EAP (strong security)\nCipher : auto\nEAP-Method : PEAP\n...\nCertificate Constraaint (Domain) : radius.wireless.utoronto.ca\n...\nAuthentication : EAP-MSCHAPv2\nIdentity : 你的 UTORid\nPassword : 你的 UTORid 密码\n```\n\n接下来把 WIFI 配置一下，让智能插座连上这个 WIFI 就好了！"},
