 How to set up jupyter notebook in server? # new jupyterlab does not allow cloudflare subdomain access no matter how you try, so we use old pip install jupyterlab==3.2.8 # set up password jupyter lab password # then modify a file 'vim ~/.jupyter/jupyter_server_config.json' to allow subdomain ``` {   "ServerApp": {     "password": "JkZ12Ij",     "allow_origin": "*",     "allow_remote_access": true   } } ~       ``` # new jupyterlab does not have 'jupyter lab' command, so you can only use 'jupyter server'.

1. Use zero built-in library or third_party package Try to use built-in functions to do the same thing.

Use no types The type will break python2.7, and it will make your code more complex if you use more than json 5 base types. Instead, use this template yingshaoxo created:   ``` Instead of using type in function, you can directly put the type after variable name, so that python2 could run it, for example: def hi(greeting_string):      result

How to reduce the burden on developers, reduce software size, optimize program performance, and increase compatibility？ For different hardware, systems, and architectures, build different software packages or repositories and let different programmers manage them. For example, vim can be divided into vim_linux, vim_windows, vim_mac, vim_android, etc. If need more precise, it can be divided into vim_linux_amd64, vim_linux_arm64 In this way, you may find that only the developers of Unix are the smartest, and their project have the least amount of code, and their software are most stable. If the project has 0 dependencies, in theory, in that hardware machine it targets to, you can use that software forever without updating or internet access. For people who are looking for general cross platform project, they are stupid. They do not own those hardware or operation systems, so they can't make sure in the future, those stuff won't change. So cross platform software is the most unsta

33. "remove every backend project that uses node third party packages, they might has backdoor that could use your VPS as their VPS to act like a general web client for hackers"   it is even worse if you use npm in root VPS, because the npm will always use new version of a package or sub_package, how can you make sure your 3000 dependencies will not have a virus that could use your VPS root permission to do bad things?   it is the same for other package manager, for example, python pip. or golang package, java package, rust package, flutter package. in chinese, people usally call those machine that has those software running 'rou ji'. """ 利用 package manager 自动更新新版本的特性，做远控 轻而易举 就算不更新，利用现有的package，二进制文件或者脚本 一个post发到黑客服务器，它就知道你的电脑能不能被控制 对于root设备，被控制就是被完全控制，对于普通设备，就是被当成hacker web 客户端，可以被拿来在网上发垃圾信息、垃圾账号注册 到时候你的ip就会被当成坏ip被服务器墙掉 """

如何制作通用浏览器，使其自适应几十年甚至几百年间的网页？ 让网站主在html meta tag下写一个数字，比如“build=1997” 那么在浏览器浏览该网页的时候，浏览器会自动切换到1997年的浏览器内核 #idea #yingshaoxo How to make a universal browser that adapts to web pages that either built decades ago or built from current time? Ask the website owner to write a number under the html meta tag, such as "build=1997". Then when the browser visit the web page, the browser will automatically switch to the 1997 browser kernel. By doing so, old webpage will work on new browser. #idea #yingshaoxo
