Interface Composition in Go: Building Complex AbstractionsApr 29, 2025 am 12:24 AMInterface combinations build complex abstractions in Go programming by breaking down functions into small, focused interfaces. 1) Define Reader, Writer and Closer interfaces. 2) Create complex types such as File and NetworkStream by combining these interfaces. 3) Use ProcessData function to show how to handle these combined interfaces. This approach enhances code flexibility, testability, and reusability, but care should be taken to avoid excessive fragmentation and combinatorial complexity.

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),

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.
