Managing Shared Names in Libraries and Binaries
When developing software, it may be desirable to have both a library and a standalone executable with the same name. This can lead to challenges in Go, as the recommended approach is for executables and libraries to have distinct names.
In the example provided, the developer is attempting to create a library for Tar operations, but also wants a standalone Tar command-line utility. The initial approach of placing the executable code in a directory named main.go within the library package doesn't work as expected.
To resolve this, it's recommended to organize the codebase as follows:
src/ tar/ tar.go # tar library tar/ main.go # tar binary
With this structure, go build -o $GOPATH/bin/tar tarbin constructs both a library named tar and a binary named tar.
If the code is hosted on GitHub, the preferred directory structure becomes:
src/ github.com/ you/ tar/ tar.go # tar library tar/ main.go # tar binary
This layout ensures that when running go get install github.com/you/tar/tar, a binary named tar is installed, and go get install github.com/you/tar installs the library named github.com/you/tar.
Depending on the primary purpose of the codebase, the library and binary can be swapped in the directory structure.
By using separate subdirectories for the library and binary within the package directory, developers can effectively manage code with shared names in Go, enabling both library and standalone executable functionality.

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),
