• Xelatex could support Chinese with ctex + Truetype/OpenType font. you could search web for detail.
• latex could support Chinese with ctex + tfm/pk font.
• pdflatex need type1 font, so tfm/pk and Truetype/OpenType font doesn’t work. But there are three ways to support Chinese for pdflatex

• ctex + simsum.ttc

• \documentclass[fontset=windows]{ctexart}
• zhmetrics provide tfm file for simsun.
• zhmetrics provide mapping file to map tfm back to simsun.ttf (Truetype), but not for other Chinese ttf font,  see /usr/share/texmf-dist/tex/generic/zhmetrics/zhwinfonts.tex
• it embedded Trutype font into pdf.

• ctex + CJKutf8 + gbsn.

• it embedded type1 font into pdf, you could use “pdffonts” to check.

\documentclass[fontset=none]{ctexart}**\usepackage{CJKutf8}
\begin{document}
\begin{CJK*}{UTF8}{gbsn}
你好，世界！
\end{CJK*}

I couldn’t connect to my raspberry pi for several days. Today I conducted a trouble shooting. 

At beginning, I think system is down due to flashcard broken but later I found raspyberry still has ipv4/ipv6 address from home router. I tried to ssh but not successful. I ping the server first, ping is Ok. Then I could ssh server successfully.

it seems i am not the only guy who has this issue, see

• Error Linter:

• pyflake
• pylint

• Complexity Analysis

• mccabe

• flake8

• flake8 = Pyflakes + pycodestyle + mccabe

• type checker:

• mypy

• run it on command line
• run it with language server, for example: pylsp
• run it with Jupyter

• nb-mypy: configure it with ipython configuration or run it with command in jupyter

• jupyter-lsp + pylsp

• Language server

• pyls and pylsp
• prefer to use pylsp instead of pyls, seelink for detail.

• difference between different linter tools

• Pylint vs Pyflakes vs Flake8 vs autopep8 vs Bandit vs Prospector vs Pylama vs Pyroma vs Black vs Mypy vs Radon vs mccabe
