Python Concurrency with asyncio.

Learn how to speed up slow Python code with concurrent programming and the cutting-edge asyncio library.

- Use coroutines and tasks alongside async/await syntax to run code concurrently
- Build web APIs and make concurrency web requests with aiohttp
- Run thousands of SQL queries concurrently
- Create a map-reduce job that can process gigabytes of data concurrently
- Use threading with asyncio to mix blocking code with asyncio code

Trio – a friendly Python library for async concurrency and I/O.

The Trio project aims to produce a production-quality, permissively licensed, async/await-native I/O library for Python. Like all async libraries, its main purpose is to help you write programs that do multiple things at the same time with parallelized I/O. A web spider that wants to fetch lots of pages in parallel, a web server that needs to juggle lots of downloads and websocket connections simultaneously, a process supervisor monitoring multiple subprocesses... that sort of thing. Compared to other libraries, Trio attempts to distinguish itself with an obsessive focus on usability and correctness. Concurrency is complicated; we try to make it easy to get things right.

Term.jl is a Julia library for stylized terminal output.

Term.jl uses a simple markup syntax to add style information to standard Julia strings. It also provides Renderable objects such as the Panel and TextBox as you can see in the example below. These too can be styled, include styled text, and they can be nested and stacked to produce structured visual displays in your terminal.

dplyr is a grammar of data manipulation, providing a consistent set of verbs that help you solve the most common data manipulation challenges:

- mutate() adds new variables that are functions of existing variables
- select() picks variables based on their names.
- filter() picks cases based on their values.
- summarise() reduces multiple values down to a single summary.
- arrange() changes the ordering of the rows.

Memray is a memory profiler for Python. It can track memory allocations in Python code, in native extension modules, and in the Python interpreter itself. It can generate several different types of reports to help you analyze the captured memory usage data.

Notable features:
• 🕵️‍♀️ Traces every function call so it can accurately represent the call stack, unlike sampling profilers.
• ℭ Also handles native calls in C/C++ libraries so the entire call stack is present in the results.
• 🏎 Blazing fast! Profiling slows the application only slightly. Tracking native code is somewhat slower, but this can be enabled or disabled on demand.
• 📈 It can generate various reports about the collected memory usage data, like flame graphs.
• 🧵 Works with Python threads.
• 👽 Works with native-threads (e.g. C++ threads in C extensions).

C3 (Custom Command and Control) is a tool that allows Red Teams to rapidly develop and utilise esoteric command and control channels (C2). It's a framework that extends other red team tooling, such as the commercial Cobalt Strike (CS) product via ExternalC2, which is supported at release. It allows the Red Team to concern themselves only with the C2 they want to implement; relying on the robustness of C3 and the CS tooling to take care of the rest. This efficiency and reliability enable Red Teams to operate safely in critical client environments (by assuring a professional level of stability and security); whilst allowing for safe experimentation and rapid deployment of customised Tactics, Techniques and Procedures (TTPs). Thus, empowering Red Teams to emulate and simulate an adaptive real-world attacker.
