我好懒决定不想写。有空再说吧。

关于这个网站 从2022年3月起一直没有更新过。后来让我改成spinx/jupyter了。 现在的状况 听了几个Ruby的演讲，发现我一直没有程序员的懒惰精神。 过去的时间 从哪里说起呢。我从3月拿到Python起，开始使用Python。在公司里做了消息模拟器。大成功。新技术才是前进的方向。 我离职了。去IBE。但是那里的情况不是很好。没有人文关怀。这是C++的通病。或许我只是想离开。 这也和住的地方有关。东三旗是一个废墟。墙太薄。空气不好。我果然需要一个高质量的生活环境。 我的新工作 后来去了微创。做英语技术支持。 但我现在已经辞职了。

I can launch backend and start debugging: uvicorn backend:app ...

I change an iso file default open program to C:\Windows\explorer.exe , and I can’t change it back. (Try this in virtual machine, not real computer.) How to change it? My OS is Windows 7.

微软总是把握软件开发的最前沿方向. 看来ML.NET需要学一学了. 希望能够改变我对机器学习的看法. 15/10/2024 更新 微软还是不行。Just a machine. C++已经过气了。

公司发了工作电脑，是笔记本ThinkBook 14 Gen2 ITL。有16GB运存和512G存储。由于我已经有了一个用来工作的笔记本，这个笔记本就被我拿到宿舍自己用了。小巧方便。 系统更新 联网激活系统后，首先下载更新。更新到了Windows 11. 安装软件 主要有V2ray、Chrome、Windows Terminal、VSCode、Telegram Desktop. 我还安装了VirtualBox用来运行虚拟机。 对了，还有Git for Windows。 虚拟机设置 安装系统后，添加网卡，设置固定IP，然后启用ssh。 通过ssh连接后，升级系统，安装常用软件。 安装cockpit sudo dnf install cockpit sudo systemctl enable --now cockpit.socket sudo firewall-cmd --add-service=cockpit sudo firewall-cmd --add-service=cockpit --permanent web控制台在9090端口。 Windows Terminal设置 更改默认配色为One Half Dark，下载Recursive Font, 更改字体为Rec Mono Linear. 设置默认字号为14，窗口大小为80*24，光标为实心框。 设置Ctrl+D退出(参考)： Set-PSReadlineKeyHandler -Key ctrl+d -Function ViExit 卸载软件 卸载联想电脑管家。
