I need to extract certain information from a bunch of images. I'm a Python developer, but know little about this niche. Can somebody suggest particular toolkits to start with?

The problem: The placement of flippers on pinball machines has a rich history. There are thousands of different pinball machines. I would like to identify broad trends and turning points. So I'd like to be able to process photos like this in bulk, spot the flippers, and record their locations relative to the rest of the playfield: https://www.ipdb.org/showpic.pl?id=20&picno=38587

I know how to get the raw data (lists of pinball machines, collection of images) but the part I don't know how to tackle is the image processing (selection of best playfield image, compensating for photographer variation, finding the flippers, extracting their position and angle).

If you've done something like this before, what has worked for you? #pinball #python

A Python Software Foundation @ThePSF rejeitou um aporte de um milhão e meio de dólares do governo americano.

O motivo? As regras do financiamento da NSF diziam que a PSF não poderia trabalhar com iniciativas de DEI (diversidade, equidade, inclusão).

A Fundação preferiu rejeitar a grana a se sujeitar a essas condições trumpistas, que vão contra sua missão e seus valores.

A missão da PSF inclui fomentar uma comunidade diversa e internacional de pythonistas.

@ThePSF My company is pretty much built on #Python.

We just made a significant donation to the PSF in recognition to their great work on the language, of which a small but important part is their commitment to fairness (or "DEI" as USians call it).

If you can, you can donate any amount at https://psfmember.org/civicrm/contribute/transact/?reset=1&id=2.

They say "don't read the comments" but I think the ratio of good vs bad comments in this thread makes it very, very worthwhile.

Also, the *reach* has been amazing. I've seen reposts from people I follow for very non-Python reasons (not mutuals!), who as far as I know have never posted or commented on Python before. ❤️

As I mentioned to @lorenipsum , it's great to not feel so alone in this.

I have nothing but respect and sympathy for @ThePSF in their decision to withdraw from the NSF grant program in order not to compromise on their mission to keep #Python a diverse and welcoming open source community

It's hard to turn down that kind of money

So, here's my .02c for it, metaphorically. I'll personally make a $1000 donation to help fill in that gap. There are certainly 1500 of us who can spare that much, in the global python community. Who's with me?

I mentioned in my @pybay welcome – #Python's vendor-neutral governance is what's made Python be successful at keeping up (and keeping ahead) of the tech industry for 30 years.

@ThePSF cannot serve private interests. We can only support what's good for the language and growing its community. And even more importantly, our board is accountable to that community.

Is that true of your preferred language's governance and nonprofit?

Shout out to the #Python Software Foundation and everyone involved for turning down a US$1.5 millon grant rather than compromise their Values.

It's easy to say we support #DEI or any other thing. It's only when we're asked to pay a price that our #Values are tested.

When asked to turn their back on DEI, the PSF passed the test. This is what resistance looks like.

I would be glad to donate to the #Python project, but doing so requires me to divulge my name and contact information as per their 501(c)(3) charitable organisation status:

"Contact information is required for tax reporting purposes and will be shared only with the US government."

Considering the current status of the US government, I don't feel comfortable doing this. Are there some other ways to donate to Python project without getting the US government involved?

So someone found a segfault in NumPy and reported it as a security bug: https://huntr.com/bounties/49928a2c-c6bb-4c1c-80ec-5d7bf708bf28. After some back and forth, the NumPy developers agreed it was a security bug (with a low score, but still).

However, since fusil had already found that crash and I had reported it 2 months earlier (https://github.com/numpy/numpy/issues/28829), the report was deemed a duplicate and no CVE was assigned.

We didn't find a CVE, but avoided one :)

Link to fix: https://github.com/numpy/numpy/pull/30071

#fusil #fuzzer #fuzzing #numpy #python

Fuzzing pyhacl (https://codeberg.org/drlazor8/pyhacl), a package of Cython bindings for HACL* (the High Assurance Cryptographic Library), with fusil we only found one crash.

It turned out to actually be a silly bug in #Cython:

Issue: https://github.com/cython/cython/issues/7263

Fix: https://github.com/cython/cython/pull/7264

Goes to show how fuzzing a C-extension can uncover crashes in many different layers.

Thanks @drlazor8 for taking up the call for C-extensions maintainers to fuzz their code.

When I discovered redlines hit top 10% on PyPI, my first reaction wasn't pride—it was surprise. "Is this even real?"

175k monthly downloads. But also:
- $0 in revenue
- 1 maintainer (me, on free time)
- No 6-month roadmap

I built it to compare legal text for myself.
Then AI learners found it useful for tracking LLM rewrites.
That never occurred to me.

After a pause, we're back to running fusil. This time, to fuzz cereggii, a package of very interesting thread synchronization utilities for #Python, made of C-extensions.

We tailored #fusil to target these #cereggii utilities, finding more issues.

Daniele Parmeggiani (dpdani), the maintainer, has been helping in the effort and being very supportive. That's the best welcome fusil has received in any project :)

Here are the issues we found: https://github.com/dpdani/cereggii/issues?q=label%3A%22fusil-fuzzer%22

#CPython #fuzzing #fuzzer

If you teach #Python, you need to recommend an editor/IDE to people who haven't already settled on a favorite of their own. When I started teaching Python, I recommended Geany. Then I moved to Sublime Text, and most recently I've been recommending VS Code.

I'm rethinking that. A fresh install of VS Code has multiple pushes for Copilot, agents, and AI chat. They come back if you just close them.

What editor/IDE would you recommend for people new to Python?

@jochie @ehmatthes Oh I was talking about the thread workers built into Textual: https://textual.textualize.io/guide/workers/#thread-workers

loop.call_soon_threadsafe() seems like a lower-level Python thing (right @stuartl ?) which would work, but I have to imagine it's not as straightforward as using the feature that Textual already provides for you.

#Python

@ehmatthes @jochie httpx is indeed the most common recommendation I've gotten for an async-capable equivalent of requests, although I don't think it qualifies as a drop-in replacement.

The alternative might be to use worker threads in Textual, if you can't switch to use httpx.

Although I'm sure there would be a lot of interest in a Mastodon client library that could be used asynchronously... 😁

#Python

Mulling over my options to make "Mastodon.py" play nice within a "Textual" (TUI) environment, with respect to making the non-streaming bits work asynchronously:

- Mastodon.py uses "requests", not "aiohttp", so I don't think asyncio is an option?
- Unclear what the current state of the art is in terms of async drop-in replacements for "requests", unsure I could override Mastodon.py's use of it anyway.
- Best option seems to be gevent and "monkey-patching", then?

#Python #AsyncIO #Programming

Been running a fusil campaign for a week, targeting a C-extension. The fuzzer has found 9 issues so far, feels good.

The maintainer is helping with the campaign and eager to fix the issues, which is great.

Some maintainers see us with suspicion and often disregard issues, as if we're after accolades, pointing fingers or complaining about the code.

We fuzz to help, that's all.

Anyway, if you have a C-extension and would like it fuzzed, hit me up :)

woke up to a notice from datadog that their #python library had a transitive dependency cause an infinite recursion when interacting with postgres. Yes, that'd explain the day I had yesterday.

turns out the transitive dependency went from 1.x.x to 2.0.0, and datadog had set an unbounded version constraint.

tl;dr: are you a library consumer? use lockfiles. are you a library author? SET YOUR FUCKING DEPENDENCIES CORRECTLY.

A paper conical #sundial

From the Sun's altitude and azimut, this sundial derives solar time, & the place on the map where the Sun is directly overhead.
Here its approx.4:20pm local solar time ; the Sun is approaching the Brazil-Bolivia border.

The diurnal arcs crossing the hour lines are the shadow's paths on the 21st of each month (approx). These lines also tell the sunrise/sunset times where they join the cone's rim.

Made with a #Python script.
Besides the usuals gnomonic calculations, I also needed a bit of #math for the developped truncated cone (called a 'frustum' !), and some #cartography work to project the coastlines and borders on the curved surface.

Exponential time is so unusual I completely left out of my article that discusses time complexity in #Python.

https://pym.dev/time-complexities/

You might counter with "we could use functools.cache to make it essentially linear time".

You're right. But this non-recursive version is pretty simple!

def fibonacci(n):
a = b = 1
for _ in range(n-1):
a, b = b, a+b
return a

And if you really cared about performance (you shouldn't) there's a constant time version.

https://pym.dev/p/3b2bt/

Today's #Python tip was about how the only time I recommend using recursion is for creating tree-like structures or traversing tree-like structures.

I didn't make a very good case for this claim and I (rightfully) got some push back on this.

The 2 classic recursion-without-a-tree examples are factorial and fibonacci.

I believe both are better implemented without recursion.

I'm not sure I can see the ground from the top of this teetering yak stack I am perched atop right now but does anyone happen to know why a fcntl struct on macOS would be laid out with no alignment, at least as per the distinction between the #python struct module's "=" vs. "@" layout

Autoposter update:

I can now post text posts to BlueSky and Mastodon. I can also post links to articles and social cards will load on both platforms (Mastodon was much easier haha). I've tested the video upload function separately for BlueSky and Mastodon, but I haven't run the upload function to run both at the same time.

Developer friends - what are other social platforms with good APIs that I can integrate into a posting tool like this?

#python

Por muito tempo eu pensei que programação não fosse minha praia, achava complexo, difícil.

Foi quando conheci Python e me encantei, comecei a fazer as coisas, ver tudo acontecendo, era mágico.

Tanto que migrei de carreira e trabalho com isso hoje. Estudei, estudei muito e continuo estudando.

Acho que isso me trouxe conhecimento e maturidade suficientes para encarar outras linguagens. E estou me surpreendendo, aprendendo Java e C# e, por incrível que pareça, gostando.

Não me considero um desenvolvedor nessas linguagens, como me considero em Python, mas acredito que se um desafio me for dado em qualquer uma delas eu posso até sofrer um pouco, mas que sairá algo sairá! 😀

#Python #Java #CSharp

Is there a name in #Python for the:

if __name__ == "__main__":
main()

block? If not, I would like to share my name for it, which is "snake magic".

I am simultaneously excited for the implementation techniques that #python free threading is going to open up for framework authors and deeply concerned about the way I see discussions going around it, as it seems application authors will be speedrunning the “you can fit so many untestable data races in here” to “you can fit so many intractable mutex deadlocks in here” pipeline that java previewed for us all in the early aughts

I benchmarked `--help` on one of my CLIs with the reference implementation for PEP 810 (Explicit lazy imports).

Because my CLI already does the "inline imports" thing of moving them into functions just before they get used, I got a speedup of x1.3.

Then I moved all the imports to the top like normal, and got a speedup of x2.9!

hot take: a big reason for the collective anxiety around free-threading is the result of decades of copium where we assured each other that it's good, actually, that #Python has a bad threading story, because threads are dAnGeRoUs and our feeble minds need protection

Now that #Python 3.14 is out and Python 3.9 is finally EOL, I'm really looking forward to using pattern matching, string enums, and keyword-only dataclasses in more codebases.

Reminder to #Python:

If you're still using PyInstaller, py2exe, py2app, etc

🎉 I hadn't kept up with what Django's Steering Council had been up to outside of random board updates, and I'm happy to share how impressed I am with how transparent they are.

They are meeting several times a month and sharing their minutes as they go. https://github.com/django/steering-council

They are even sharing on the Django Forum to bring more visibility to what they are doing https://forum.djangoproject.com/t/django-steering-council-meetings-2025/38306

These are very welcoming changes. 👏👏

#Django #Python

I am doing a new #Python project, where I will try out #HTMX, and I intend to reach out to #Durus and #Quixote again – it's impressive how well old tools continue to be useful and powerful, and how their power increases with more usage.

I also keep learning new things. For example yesterday I discovered that the objects returned by dict.keys(), dict.values() and dict.items() are dynamic view objects!

And here I thought I was going to get work done today lol. Fuck #python and the cultural "fuck you" it gives to any semblance of stability.

Let me just figure out which funky set of symlinks and different versions of different modules I have to bodge together to get this one thing working, and will it break other stuff I need?

You're goddamn fucking right it will. Fuck Python.

I've been annoyed by my lack of a way to put "multi-line one-liner" python code into my bash code with reasonable indentation.

This discussion suggested a workaround: Make the first line `if 1:`, then you can indent all you like on the second line. Good enough for me!

lafleur, the CPython JIT fuzzer, now can compare timings for running a piece of code with JIT on and off.

The idea is that if the run with JIT on is much slower that with JIT off, we have found a performance bug.

Brandt Bucher suggested this mode. It took a while to get started on it, but it was simple to implement on top of Differential Mode.

So many modes, so little compute available...

An empirical evaluation of property-based testing in Python. ~ Savitha Ravi, Michael Coblenz. https://dl.acm.org/doi/10.1145/3764068 #Python #Programming

Hey, any Python experts want to help a Python newbie out? I've been hacking for decades, but I can't say I know Python best practices.

I'm working on https://github.com/Ovid/sqlitch-v2 (porting some Perl code to Python) and while it seems good to me (but very much alpha and a WIP), I don't know what I don't know. If there's anything obvious I've missed or is unpythonic, I would love to know.

Differential Mode has just landed in lafleur, the CPython JIT fuzzer. It runs the same code with and without the JIT, compares the result, and flags any discrepancies.

It does this while mutating the code in a feedback-guided loop, so it evolves the fuzzing scripts trying to find one where the JIT gives wrong results.

This is actually the 2nd time this feature is implemented (now better and more robust): it used to work, broke, and now is back.

Nice benchmark comparison of various #Python versions from @miguelgrinberg

Key takeaway: if you want to do a bubble sort, use Pypy or Rust.

Ok no. 3.14 is the fastest CPython. The JIT is still a work in progress. Free-threaded interpreter is quite nice for multithreading, but not regular stuff yet. Pypy is faster than any CPython. By a lot. But if speed's all you care about, maybe Rust.

Have been getting back into python programming and must say the new tooling is giving me hope.

I always liked python for small projects, but dealing with environments was never my favourite part.

UV seems to solve my past issues with python! Though not so sure how it will end up on the long-term. UV is made by a company that has seemingly no business plan and is backed by Venture Capital money.

But yeah I need to properly get back into python first.

macOS installer done, next on the final publishing and announcing steps.

#Python #Python314 #release

The Windows build is ready and macOS is underway.

#Python #Python314 #release

The Windows build has been started.

The jobs with profile-guided optimisation (PGO) build once, then collect a profile by running the tests, and then build again using that profile, to see how "real" code executes and optimises for that.

https://dev.azure.com/Python/cpython/_build/results?buildId=164907&view=results

Meanwhile, the docs+source+Android build has finished and the artifacts have been copied to where they need to go with SBOMs created.

#Python #Python314 #release

(That's actually the second CI attempt, we had to update some script arguments following an Android test runner update.)

This build takes about half an hour.

I've also informed the Windows and macOS release managers about the tag and they will start up installer builds.

This takes a few hours, so I've got time to finish up the release notes.

PEP 101 is the full process, but much is automated and we don't need to follow it all manually.

https://peps.python.org/pep-0101/

#Python #Python314 #release

Next up, merge and backport the final change to What's New in Python 3.14 to declare it latest stable.
https://github.com/python/cpython/pull/139631

Now start run_release.py, the main release automation script, which does a bunch of pre-checks, runs blurb to create a merged changelog, bumps some numbers, and pushes a branch and tag to my fork. It'll go upstream at the end of a successful build.

Then kick off the CI to build source zips, docs and Android binaries.

Release day!

First off, check blockers and buildbots.

A new release-blocker appeared yesterday (because of course) but it can wait until 3.14.1.

https://github.com/python/cpython/labels/release-blocker

Three deferred-blockers are also waiting until 3.14.1.

https://github.com/python/cpython/labels/deferred-blocker

A new tier-2 buildbot failure appeared yesterday (because of course) but it had previously been offline for a month and will need some reconfiguration. Can ignore.

https://buildbot.python.org/#/release_status

OK, let's make a Python!

#Python #Python314 #release

@chrisjrn.fyi Interesting proposal they're making there.

I've been tinkering with the AI-assisted autocompletion in #PyCharm recently - only on open source projects so no concerns about code privacy - and it's been slightly helpful but overall a very mixed bag. It'll be interesting to see if it gets better as they collect more data.

I’m somewhat exhausted to announce attrs 25.4.0!

The main reason for this release (and why it's published today) is that it ships the first pieces of work for Python 3.14 and PEP 749. There will be more work required and there's going to be a lot more churn once everyone starts testing 3.14 earnestly. We hope to receive more feedback before spending more time on this. #Python

I hear there's another big release tomorrow? This release adds support for Python 3.14 and for once code changes were needed due to AST deprecation removals.

Also drop support for almost-very-nearly-EOL Python 3.9.

@wildrikku @mark Wait there's *another* requests library? 😵‍💫 I'm talking about this one: https://pypi.org/project/requests/

I'd add that I think one of the emerging strengths of Python is how easy it makes it to use dependencies, especially with inline script metadata (https://packaging.python.org/en/latest/specifications/inline-script-metadata/). So the reasons to avoid dependencies are getting less and less relevant, and people who dogmatically insist on avoiding dependencies without a good reason - not saying that's you, but those people are out there - appear increasingly out of touch with modern best practices.

That being said, I still think it'd be a big improvement if the Python stdlib included better-designed URL handling modules, but realistically, I don't think that's going to happen. It's just that, because of the rich third-party library ecosystem, that's not as big of a problem as it would otherwise be.

@wildrikku To be fair, the URL handling is a particularly poorly structured portion of the #Python standard library. (Partly because the documentation for `HTTPResponse` lives at a very non-obvious place, https://docs.python.org/3/library/http.client.html#httpresponse-objects)

Most people just use external libraries like `requests` or `httpx`, which are much easier to use than the standard library's `urllib`; I would recommend that.

I'm still not having a great time with #Python. Seemingly simple things require poking around and searching on StackOverflow to an extent C# and PHP avoid by having better docs. I recently made a parser with BeautifulSoup. Now I wanted to extent the code to make another parser but this time the response is JSON, not HTML. It took me like 15 min to figure out which method I need because urlopen() returns Any so my IDE can't help and HTTPRequest, which is what it really returns, is undocumented.

And back to green!

Can anyone tell me why #python random.sample() *requires* deriving from collections.abc.Sequence?

if not isinstance(population, _Sequence):
raise TypeError("Population must be a sequence. "
"For dicts or sets, use sorted(d).")

I want to sample from a third-party package's list-like collection. It has a working __len__, __getitem__, and __iter__, which is all sample() needs. But it can't be sampled as it doesn't inherit from Sequence.

Given Python's usual ducktyping, this feels wrong.

I don't want to use anything Microsoft or Microsoft-adjacent for authoring Python. I *had* been using PyCharm Community Edition, because that tends to be the preferred IDE at work. However, with JetBrains now making us opt-out of something AI related (I don't even care what the details are), I want to use something else.

Zed looking interesting, but it's AI front and center.

At this rate I'll end up on Thorny or something. But seriously, what simple IDE are people using these days?

@helge I don't think there's a formal reporting mechanism for this. Since PyPI doesn't do anything special when a package is abandoned, there wouldn't be any point.

If a project being abandoned is causing some sort of particularly dangerous situation, I suppose one could contact the PyPI admins and ask them to do something about it manually. No guarantee on whether they would or not though 🤷 I think they typically take a hands-off approach by default.

How do venvs actually work? The python "binary" inside a venv is just a symlink to the system wide python. The activate script effectively sets VIRTUAL_ENV and prepends PATH. So why can't I have the same effects by just setting those two environment variable manually? Why can't modules of packages installed inside the venv be found by gunicorn when setting both env variables in a systemd unit and starting gunicorn that was installed by apt?

When people have pushed that around me, I show them the Zen of Python. It's important enough that it's the climactic line.

> Namespaces are one honking great idea -- let's do more of those!

`from x import y` throws one of Python's greatest features in the trash, and mashes everything into a single namespace, with all the opportunities for collisions, accidental overwrites, thinkos, and other problems.

#NPM from #Node.js ended up in the hands of Microsoft.

#RubyGems from #Ruby ended up in the hands of a nazi libertarian.

It feels like #OSS and #FOSS are being attacked on a daily basis.

Do anyone have information regarding #PyPi from #Python, is it also compromised? As far as I know, PyPi stopped working with pip search ("Use the browser") and the website needs JS to function (because it uses some PoW browser checking), so using Lynx or elinks as a sysadmin on a terminal-only machine in order to search for Python packages have been a no-no. Wonder how much it's due to similar phenomenon going on with Ruby and Node.js ecosystems.

I was added to the Python GitHub organization as a triager a couple of weeks ago. Feels so good, and makes me want to help even more!

Triaging CPython issues now is very different: there's a very active and attentive triage team, the number of issues has grown, we use GitHub instead of RoundUp etc.

I want to write a program to extract a list of clickable links from a PDF page.

#pypdf can list the link positions/sizes and target URLs. But in a PDF document, links are annotations, which are separate data from the document text.

This tutorial will guide you through building a simple ActivityPub bot using Python. The bot will listen for mentions and, when it receives a message in a specific format, it will schedule and send a reminder back to the user after a specified delay.

For example, if a user mentions the bot with a message like "@reminder@your.host.com 10m check the oven", the bot will reply 10 minutes later with a message like "🔔 Reminder for @user: check the oven".

Prerequisites

To follow this tutorial, you will need Python 3.10+ and the following libraries:

• apkit[server]: A powerful toolkit for building ActivityPub applications in Python. We use the server extra, which includes FastAPI-based components.
• uvicorn: An ASGI server to run our FastAPI application.
• cryptography: Used for generating and managing the cryptographic keys required for ActivityPub.
• uv: An optional but recommended fast package manager.

You can install these dependencies using uv or pip.

# Initialize a new project with uv
uv init

# Install dependencies
uv add "apkit[server]" uvicorn cryptography

Project Structure

The project structure is minimal, consisting of a single Python file for our bot's logic.

.
├── main.py
└── private_key.pem

• main.py: Contains all the code for the bot.
• private_key.pem: The private key for the bot's Actor. This will be generated automatically on the first run.

Code Walkthrough

Our application logic can be broken down into the following steps:

1. Imports and Configuration: Set up necessary imports and basic configuration variables.
2. Key Generation: Prepare the cryptographic keys needed for signing activities.
3. Actor Definition: Define the bot's identity on the Fediverse.
4. Server Initialization: Set up the apkit ActivityPub server.
5. Data Storage: Implement a simple in-memory store for created activities.
6. Reminder Logic: Code the core logic for parsing reminders and sending notifications.
7. Endpoint Definitions: Create the necessary web endpoints (/actor, /inbox, etc.).
8. Activity Handlers: Process incoming activities from other servers.
9. Application Startup: Run the server.

Let's dive into each section of the main.py file.

1. Imports and Configuration

First, we import the necessary modules and define the basic configuration for our bot.

# --- Logging Setup ---
logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

# --- Basic Configuration ---
HOST = "your.host.com"  # Replace with your domain
USER_ID = "reminder"      # The bot's username

Make sure to replace your.host.com with the actual domain where your bot will be hosted. These values determine your bot's unique identifier (e.g., @reminder@your.host.com).

2. Key Generation and Persistence

ActivityPub uses HTTP Signatures to secure communication between servers. This requires each actor to have a public/private key pair. The following code generates a private key and saves it to a file if one doesn't already exist.

# main.py (continued)

# --- Key Persistence ---
KEY_FILE = "private_key.pem"

# Load the private key if it exists, otherwise generate a new one
if os.path.exists(KEY_FILE):
    logger.info(f"Loading existing private key from {KEY_FILE}.")
    with open(KEY_FILE, "rb") as f:
        private_key = crypto_serialization.load_pem_private_key(f.read(), password=None)
else:
    logger.info(f"No key file found. Generating new private key and saving to {KEY_FILE}.")
    private_key = rsa.generate_private_key(public_exponent=65537, key_size=2048)
    with open(KEY_FILE, "wb") as f:
        f.write(private_key.private_bytes(
            encoding=crypto_serialization.Encoding.PEM,
            format=crypto_serialization.PrivateFormat.PKCS8,
            encryption_algorithm=crypto_serialization.NoEncryption()
        ))

# Generate the public key from the private key
public_key_pem = private_key.public_key().public_bytes(
    encoding=crypto_serialization.Encoding.PEM,
    format=crypto_serialization.PublicFormat.SubjectPublicKeyInfo
).decode('utf-8')

3. Actor Definition

Next, we define the bot's Actor. The Actor is the bot's identity in the ActivityPub network. We use the Application type, as this entity is automated.

# main.py (continued)

# --- Actor Definition ---
actor = Application(
    id=f"https://{HOST}/actor",
    name="Reminder Bot",
    preferredUsername=USER_ID,
    summary="A bot that sends you reminders. Mention me like: @reminder 5m Check the oven",
    inbox=f"https://{HOST}/inbox",      # Endpoint for receiving activities
    outbox=f"https://{HOST}/outbox",    # Endpoint for sending activities
    publicKey=CryptographicKey(
        id=f"https://{HOST}/actor#main-key",
        owner=f"https://{HOST}/actor",
        publicKeyPem=public_key_pem
    )
)

4. Server Initialization

We initialize the ActivityPubServer from apkit, providing it with a function to retrieve our Actor's keys for signing outgoing activities.

# main.py (continued)

# --- Key Retrieval Function ---
async def get_keys_for_actor(identifier: str) -> list[ActorKey]:
    """Returns the key for a given Actor ID."""
    if identifier == actor.id:
        return [ActorKey(key_id=actor.publicKey.id, private_key=private_key)]
    return []

# --- Server Initialization ---
app = ActivityPubServer(apkit_config=AppConfig(
    actor_keys=get_keys_for_actor  # Register the key retrieval function
))

5. In-Memory Storage and Cache

To serve created activities, we need to store them somewhere. For simplicity, this example uses a basic in-memory dictionary as a store and a cache. In a production application, you would replace this with a persistent database (like SQLite or PostgreSQL) and a proper cache (like Redis).

# main.py (continued)

# --- In-memory Store and Cache ---
ACTIVITY_STORE = {} # A simple dict to store created activities
CACHE = {}          # A cache for recently accessed activities
CACHE_TTL = timedelta(minutes=5) # Cache expiration time (5 minutes)

6. Reminder Parsing and Sending Logic

This is the core logic of our bot. The parse_reminder function uses a regular expression to extract the delay and message from a mention, and send_reminder schedules the notification.

# main.py (continued)

# --- Reminder Parsing Logic ---
def parse_reminder(text: str) -> tuple[timedelta | None, str | None, str | None]:
    """Parses reminder text like '5m do something'."""
    # ... (implementation omitted for brevity)

# --- Reminder Sending Function ---
async def send_reminder(ctx: Context, delay: timedelta, message: str, target_actor: APKitActor, original_note: Note):
    """Waits for a specified delay and then sends a reminder."""
    logger.info(f"Scheduling reminder for {target_actor.id} in {delay}: '{message}'")
    await asyncio.sleep(delay.total_seconds()) # Asynchronously wait
    
    logger.info(f"Sending reminder to {target_actor.id}")
    
    # Create the reminder Note
    reminder_note = Note(...)
    # Wrap it in a Create activity
    reminder_create = Create(...)
    
    # Store the created activities
    ACTIVITY_STORE[reminder_note.id] = reminder_note
    ACTIVITY_STORE[reminder_create.id] = reminder_create
    
    # Send the activity to the target actor's inbox
    keys = await get_keys_for_actor(f"https://{HOST}/actor")
    await ctx.send(keys, target_actor, reminder_create)
    logger.info(f"Reminder sent to {target_actor.id}")

7. Endpoint Definitions

We define the required ActivityPub endpoints. Since apkit is built on FastAPI, we can use standard FastAPI decorators. The main endpoints are:

• Webfinger: Allows users on other servers to discover the bot using an address like @user@host. This is a crucial first step for federation.
• /actor: Serves the bot's Actor object, which contains its profile information and public key.
• /inbox: The endpoint where the bot receives activities from other servers. apkit handles this route automatically, directing activities to the handlers we'll define in the next step.
• /outbox: A collection of the activities created by the bot. but this returns placeholder collection.
• /notes/{note_id} and /creates/{create_id}: Endpoints to serve specific objects created by the bot, allowing other servers to fetch them by their unique ID.

Here is the code for defining these endpoints:

# main.py (continued)

# The inbox endpoint is handled by apkit automatically.
app.inbox("/inbox")

@app.webfinger()
async def webfinger_endpoint(request: Request, acct: WebfingerResource) -> Response:
    """Handles Webfinger requests to make the bot discoverable."""
    if not acct.url:
        # Handle resource queries like acct:user@host
        if acct.username == USER_ID and acct.host == HOST:
            link = WebfingerLink(rel="self", type="application/activity+json", href=actor.id)
            wf_result = WebfingerResult(subject=acct, links=[link])
            return JSONResponse(wf_result.to_json(), media_type="application/jrd+json")
    else:
        # Handle resource queries using a URL
        if acct.url == f"https://{HOST}/actor":
            link = WebfingerLink(rel="self", type="application/activity+json", href=actor.id)
            wf_result = WebfingerResult(subject=acct, links=[link])
            return JSONResponse(wf_result.to_json(), media_type="application/jrd+json")
    return JSONResponse({"message": "Not Found"}, status_code=404)

@app.get("/actor")
async def get_actor_endpoint():
    """Serves the bot's Actor object."""
    return ActivityResponse(actor)

@app.get("/outbox")
async def get_outbox_endpoint():
    """Serves a collection of the bot's sent activities."""
    items = sorted(ACTIVITY_STORE.values(), key=lambda x: x.id, reverse=True)
    outbox_collection = OrderedCollection(
        id=actor.outbox,
        totalItems=len(items),
        orderedItems=items
    )
    return ActivityResponse(outbox_collection)

@app.get("/notes/{note_id}")
async def get_note_endpoint(note_id: uuid.UUID):
    """Serves a specific Note object, with caching."""
    note_uri = f"https://{HOST}/notes/{note_id}"
    
    # Check cache first
    if note_uri in CACHE and (datetime.now() - CACHE[note_uri]["timestamp"]) < CACHE_TTL:
        return ActivityResponse(CACHE[note_uri]["activity"])
        
    # If not in cache, get from store
    if note_uri in ACTIVITY_STORE:
        activity = ACTIVITY_STORE[note_uri]
        # Add to cache before returning
        CACHE[note_uri] = {"activity": activity, "timestamp": datetime.now()}
        return ActivityResponse(activity)
        
    return Response(status_code=404) # Not Found

@app.get("/creates/{create_id}")
async def get_create_endpoint(create_id: uuid.UUID):
    """Serves a specific Create activity, with caching."""
    create_uri = f"https://{HOST}/creates/{create_id}"
    
    if create_uri in CACHE and (datetime.now() - CACHE[create_uri]["timestamp"]) < CACHE_TTL:
        return ActivityResponse(CACHE[create_uri]["activity"])
        
    if create_uri in ACTIVITY_STORE:
        activity = ACTIVITY_STORE[create_uri]
        CACHE[create_uri] = {"activity": activity, "timestamp": datetime.now()}
        return ActivityResponse(activity)
        
    return Response(status_code=404)
