  • fastapi

    FastAPI framework, high performance, easy to learn, fast to code, ready for production

    Project mention: Litestar – powerful, flexible, and highly performant Python ASGI framework | | 2024-02-26

    It’s been my experience that async Python frameworks tend to turn IO bound problems into CPU bound problems with a high enough request rate, because due to their nature they act as unbounded queues.

    This ends up made worse if you’re using sync routes.

    If you’re constrained on a resource such as a database connection pool, your framework will continue to pull http requests off the wire that a sane client will cancel and retry due to timeouts because it takes too long to get a connection out of the pool. Since there isn’t a straightforward way to cancel the execution of a route handler in every Python http framework I’ve seen exhibit this problem, the problem quickly snowballs.

    This is an issue with fastapi, too-

    🔎 Hunt down social media accounts by username across social networks

    Project mention: Checking all accounts associated with my email address? | /r/PrivacySecurityOSINT | 2023-11-12

    In the interest of cleaning my digital life a bit I really want to delete all of my old accounts that I no longer use. The terminal application "Sherlock" on github can search for instances of a username you input and find associated websites. Sherlock

  • WorkOS

  • rich

    Rich is a Python library for rich text and beautiful formatting in the terminal.

    Project mention: Neat Parallel Output in Python | | 2024-02-25

    There is an open issue [1] on GitHub to make it more modular and get rid of markdown and syntax highlighting but I have no hope for rich to get more minimal.

  • celery

    Distributed Task Queue (development branch)

    Project mention: Streaming responses to websockets with multiple LLMs, am I going about this wrong? | /r/LangChain | 2023-06-20

    So this might be my understanding, but stuff like celery is more like an orchestrator that chunks up workloads (think Hadoop with multiple nodes).

  • pyxel

    A retro game engine for Python

    Project mention: Show HN: Driftmania – an open source PICO-8 racing game | | 2024-02-16

    Nice work, gives me very Micro Machines vibes for the NES. The only thing I don't like about PICO-8 is that its completely closed source. An open source alternative that seems very promising is Pyxel. It has similar retro / pixel art limitations, a built-in sprite editor, music tracker, etc.

  • memray

    Memray is a memory profiler for Python

    Project mention: Memray – A Memory Profiler for Python | | 2024-02-10

    I collected a list of profilers (also memory profilers, also specifically for Python) here:

    Currently I actually need a Python memory profiler, because I want to figure out whether there is some memory leak in my application (PyTorch based training script), and where exactly (in this case, it's not a problem of GPU memory, but CPU memory).

    I tried Scalene (, which seems to be powerful, but somehow the output it gives me is not useful at all? It doesn't really give me a flamegraph, or a list of the top lines with memory allocations, but instead it gives me a listing of all source code lines, and prints some (very sparse) information on each line. So I need to search through that listing now by hand to find the spots? Maybe I just don't know how to use it properly.

    I tried Memray, but first ran into an issue (, but after using some workaround, it worked now. I get a flamegraph out, but it doesn't really seem accurate? After a while, there don't seem to be any new memory allocations at all anymore, and I don't quite trust that this is correct.

    There is also Austin (, which I also wanted to try (have not yet).

    Somehow this experience so far was very disappointing.

    (Side node, I debugged some very strange memory allocation behavior of Python before, where all local variables were kept around after an exception, even though I made sure there is no reference anymore to the exception object, to the traceback, etc, and I even called frame.clear() for all frames to really clear it. It turns out, frame.f_locals will create another copy of all the local variables, and the exception object and all the locals in the other frame still stay alive until you access frame.f_locals again. At that point, it will sync the f_locals again with the real (fast) locals, and then it can finally free everything. It was quite annoying to find the source of this problem and to find workarounds for it.

  • pwntools

    CTF framework and exploit development library

    Project mention: PwnTools for Exploit Development | | 2023-08-20

    The Pwntools library stands out as a sophisticated toolset for CTF enthusiasts and security researchers. It aids in creating and executing shellcode, designing payloads, and interacting with remote processes. For instance, the context feature allows developers to switch between different architectures effortlessly, while the 'tube' module streamlines the communication between local and remote processes. And it's not just limited to Linux; the library has support for various platforms including Windows, making it versatile and comprehensive.

  • Osintgram

    Osintgram is a OSINT tool on Instagram. It offers an interactive shell to perform analysis on Instagram account of any users by its nickname

    Project mention: facebook hack | /r/Kalilinux | 2023-06-28

    If the tattoo studios aren't necessary to have been from facebook specifically, Osintgram is a pretty effective tool for scraping shit from Instagram really quickly that could theoretically be used to achieve this, if not perhaps in a roundabout sort of way like starting from one business you know and getting shit from their friends' info and so on. I could swear that I had known about a similar tool for facebook, but I'm drawing a blank right now...

  • ImageAI

    A python library built to empower developers to build applications and systems with self-contained Computer Vision capabilities

    Project mention: Photo gallery frontend with encryption and search | /r/selfhosted | 2023-11-27

    Hi. I want to implement an image server similar to Photoprism using ImageAI to tag images based on objects and context. However I don't want to spend to much time working on the frontend, at first I were thinking about using Danbooru and use Flexbooru or the web interface on my phone. But it doesn't have any encryption or password protection (since the purpose of it is to be used as a public image board).
