`git clone https://github.com/pytorch/pytorch` hangs

After adding verbose switch: git clone https://github.com/pytorch/pytorch -v, we get:

Cloning into 'pytorch'...
POST git-upload-pack (175 bytes)
POST git-upload-pack (chunked)

According to StackOverflow:

This is a bug in Git; when using HTTPS it will use chunked encoding for uploads above a certain size. Those do not work. A trivial fix is to tell git to not chunk until some ridiculously large size value...

Add this to ~/.gitconfig:

[http]
        postBuffer = 157286400

Sins of Tencent LLC 腾讯的几宗“罪”

2023-04-14 |robot

微信

登陆只能用手机扫QR code，企图用手机App OTP替代传统用户名密码
不支持消息同步：e.g. 电脑上新安装client后无法显示行动装置可见之历史消息。换了新设备，旧设备上的群不见了。
垄断了IMS中国市场，导致大量人对互联网Internet存在误解，企图用“公众号”代替传统Website，e.g. 使用了web技术但不支持web标准（仅可专用客户端即微信App访问，不支持搜索服务检索），网页lazy load富媒体内容导致浏览体验极差
人在大量不适宜应用微信之场合强行应用微信及关联腾讯应用，e.g. 国人不懂RSS订阅、Jira之类的进度跟踪软件、邮件列表；凡事建形形色色的“群”，不论什么轻重缓急的消息都往“群”里发
功能臃肿，企图以小程序代替apk，实现系统中之系统，将支付与IMS等众多功能进行绑定导致使用者的数字生活高度依赖于腾讯，存在单点故障风险
数据存储使用私有格式和方式，且有异常巨量存储空间占用报道，且用户无法导出为结构化数据进行查看、备份等管理作业（截图行为导致结构化文本信息降级成像素信息）

QQ空间

莫名奇妙的、不对用户解释的关键词检测
邪恶的广告投送

Content Management

Among copious open-source content management system(CMS) or Markup-to-HTML software, e.g. MediaWiki, WordPress, Hugo, Hexo, Sphinx, Typecho is more lightweight than WordPress, and by utilizing PHP, it is full-featured compared to Markup-to-HTML software that requires a webserver to host the generated static html and js files.

Web server

Caddy has a simple yet powerful configuration syntax, yet it provide nearly the same functionality of nginx.

Operating system

Linux is more secure than Windows and supports more hardward than BSD family. Among all Linux distributions, Archlinux is the best one as it favors KISS principle, always come with up-to-date software packages using an efficient package management system.
