Every programmer needs to master at least three programming languages . Of course, this is just my opinion.
This is a view I have developed over the years. It may be a bias, but I can quickly understand a programmer based on the programming language he likes. When I read resumes, I try to use my set of ideas to sort them by "why this programmer uses this programming language." I use my biases to select the resumes I want from the pile.
一.The language of happiness
It’s a language you use to think. This is a language you want to use all the time. This is a language for writing your own projects. For me, it’s OCaml ( and now JavaScript, although I’m absorbing CoffeeScript into my world). For many people it might be LISP or Haskell . When a person tells me his happy language, I can identify many characteristics of this person based on this.
If the language is a very esoteric or new language, it means he has a passion for programming.
If this language is a mainstream language, it shows that he is wise or pragmatic.
二.Prolific / Powerful language
This language should be experienced and all-encompassing. It is mature and has a large base library. Using this language, it can quickly help you develop various services or command line tools in a pinch. A few taps of your fingertips and everything is done.
If a programmer lists many such languages, it may mean that he can use all these languages to develop RESTful services.
If I don't find that he has high language production, or very little, then I will suspect that he either lacks experience or is not professional enough.
Three.Butter + Bread
This is the language that makes you live when life is tight. It’s a language you only need when you or your family needs you to struggle.
If a person does not master a language that can be exchanged for bread and butter, then he probably needs to receive some education on how to work efficiently in a team.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
