Bob Belderbos: Ship Your First Python App: a Free Course on the Local Dev Workflow
I keep hearing this a lot: the Python syntax I picked up in an afternoon, but shipping a real project meant learning ten more things. There is a stark difference between writing some code in Python vs building an app that someone else can run on their system. These skills are taught, but rarely together in one place. So I am building a free course to teach this.
The gap I want to help close
I spotted a post on r/learnpython recently of someone who had done several courses, worked with pandas, NumPy, and scikit-learn, and understood the language well, but had never learned the complete development cycle. The confusion:
- Installing Python
- Using the terminal
- Installing packages with pip
- Virtual environments
- Choosing/configuring the correct Python interpreter
- Organizing a project
- Saving and reusing dependencies
- Running and debugging code
- Git and GitHub
- Understanding how to share a project with someone else
- Understanding what I actually need to install versus what belongs inside my project
And the framing was spot on:
I'm not looking for another beginner Python programming course. [...] What I need is something that teaches me how to actually work as a Python developer on my own computer.
None of that is Python the language. It's the workflows around it, and it is genuinely the harder part to learn, because a. it's often skipped over or set up for you, and b. it's a lot of moving parts touching adjacent domains: the OS, the shell, the editor, the package manager, and git / GitHub.
You can learn Python without ever learning any of that (e.g. using it in a notebook), but building a real shared project without these skills is not possible.
Fortunately things timed well. One of the developers I'm currently coaching started mentoring beginners at her company, and she confirmed this gap: getting Python and package management working locally is where a lot of people still get stuck, often before they write a single line of code.
The course: 6 weeks, one small app
So I'm building Ship Your First Python App, a 6-week course that teaches the local development workflow from scratch by building a small command-line app: a dev journal.
The first week is live, and every Friday a new week is released. The course is free, self-paced, and right here on this site. You can start it right now.
This is the course that person on Reddit was looking for.
Here is what you'll learn each week:
- Week 1) Project Setup & Data Model (live now): the terminal, Git, SSH keys and your first pull request, starting a project with
uv, and modeling data with a dataclass serialized to JSON. - Week 2) CLI & Type Safety (Sep 25): wrap it in a real command-line interface using the Typer library, add type hints, and handle errors so users get a clean message instead of a traceback.
- Week 3) Features & Search (Oct 2): case-insensitive search, tag filtering, and limiting to only see the most recent entries.
- Week 4) Code Organization & Testing (Oct 9): split one file into modules, making a proper package, group persistence into a class, and share test setup with pytest fixtures.
- Week 5) Test Coverage & Polish (Oct 16): using the Rich library to nicely format an output table, and measuring coverage with pytest-cov to find untested code.
- Week 6) Ship It (Oct 23): write a README, do the final verification pass, merge, and optionally publish the package to PyPI or add a (web) frontend.
Each week you're handed a failing test suite and write the code to make it pass, so you are always coding against a clear spec and reading real pytest along the way. You also make a new branch and open a pull request each week, so you practice the full cycle of a real project. This mirrors how I work in my Snipster, Rust and Agentic AI cohort programs.
Who it is for + feedback appreciated
You can read and understand basic Python code, but you struggle with all the pieces around it required to ship an app. Or you've done that but you want a refresher on the newer tooling like uv and ruff. You have scripted in Python but want to ship a small project end-to-end using the proper workflows.
You do not need prior experience with CLIs, packaging, or git. That's what this course will teach. I hope you're excited to dive in and learn this critical piece of Python software development with me. You'll see the weeks unlock as we go. It's very important to me to get feedback to make this as useful, practical and pleasant as possible.
Don't hesitate to hit me up on X, LinkedIn or email me with your thoughts.
Have fun and learn a lot! π

Django Weblog: Proposed change to DSF voting membership
We're proposing a new voting membership status to help us track active members. If you've voted in a Board election in the last two years, you're active, and you count toward quorum. If you haven't, you're still a member, but you won't count toward quorum until you tell us you want to vote.
Why make this change?
Quorum today is measured against every member on the rolls, including members who no longer take part in elections. As membership grows, quorum becomes harder to reach and puts our elections' validity at risk.
Defining a quorum around active members is standard practice for nonprofits. Counting the entire membership roll is the outlier.
The Python Software Foundation takes a similar approach. Its voting members are asked to affirm that they intend to vote, and in June 2024 the PSF board approved waiving that affirmation for anyone who voted in the previous board election (board minutes).
No one loses their membership under this change. You remain a member and stay listed on the website. Active status only affects how we count quorum. This keeps our rolls accurate and our elections valid.
We don't want anyone excluded because they missed an email. We'll send reminders before each election and post on our blog and the forum, so everyone has plenty of notice. If you want to vote, contact us before the election opens, and we'll add you to the roll.
We've proposed the corresponding bylaw change on GitHub, discussed this proposal on the Django Forum for a while, and talked it through in person at DjangoCon US.
Next steps
This is a call for public comment. Please share your feedback by October 7, 2026, either on the pull request or, if you're a DSF member, in the members-only Forum thread.
The Board will review the comments, and if the community raises no major objections, the Board will vote on the change at our October 8th Board of Directors meeting.

ListenData: AutoGPT : Everything You Need To Know
In this post we have covered AutoGPT in detail. By end of this tutorial, you will not only understand how it works but also will be able to run it on your system. Auto-GPT has gained a significant amount of popularity in the media. It has become one of the most talked-about topics across various social media platforms after ChatGPT. It has not only captured the attention of people in Artifical Intelligence community but also people from other background. Media outlets across countries covered it and reported how it can automate everything ranging from simple to complex tasks.

What is AutoGPT?
AutoGPT is an experimental open-source project built on the latest ChatGPT model i.e GPT-4. It is not limited to ChatGPT as it can also do web search and try to find information from internet. When a client gives us a project with instructions on what to do. We, as analysts, perform tasks to fulfill the project requirements. In the same way, by assigning a project to AutoGPT, it will do on its own all the necessary tasks to meet the project's requirements.
Let's say you ask AutoGPT to do market research about different headphones in the market. It will do web search and try to find this information on internet and produce output for you in a cleaned and structured format. See the video below.

September Python Leiden meetup summaries
Two summaries from the September 2026 https://pythonleiden.nl/.
Maintaining Python packages to attract free and open source software contributors - Steve Piercy
Steve is in the Netherlands for next week's Plone conference in Maastricht (NL). He's been involved in open source software for over two decades.
What are contributors? Contributors to open source software? Why do you do it? Learning (I myself got a good programming education out of contributing to Zope/Plone while still at the university). You might want to give back. You might like the community, you like to belong to the community. Finding your tribe. Perhaps build a resume or CV. Help other people.
Why not? Negative online reactions. You want to really make money out of it. AI slop. You might not have time. Too busy. Life happens. You might enjoy walking your dog or doing gardening more. Or perhaps you just don't know how! Or you don't feel experienced enough (imposter syndrome). Perhaps you don't think your English is good enough (he advocates just using Google Translate).
(He asked how many people had already contributed to open source: about half the room raised their hands.)
There are actually lots of ways to contribute. It is not all code! Read this page for some examples. You can report security vulnerabilities or issues. You can comment on issues and help getting them forward. Review pull requests. Extend the documentation. You can join discussions in forums or on Matrix. Write a blog post on a project. And... you can financially sponsor a project.
(He again asked who had contributed: now most hands went up!)
Where to start? Start with what you use and what you find interesting. This helps staying involved and getting into the community more and more. He himself liked web applications and especially forms: making sure they're intuitive and safe and well-validated. And he liked documentation, so some of his first contributions were documentation fixes for open source projects.
Recently, he volunteered to take over maintainership of an open source project (a sphinx extension). There were lots of open pull requests and he asked the owners to look at it again and perhaps tweak it a bit and... everybody responded and a few weeks later he could make a new release with lots of fixes.
What is a maintainer? Well, basically maintainers are contributors who make releases. But ideally you also have to "tend your garden" and try to get your small community to thrive. One thing to keep in mind: you have to put your ego aside. If it is open source, it is really owned by your users, not by you. What do you have to do? Show up when someone has a question. Document your project (how to contribute, how to report bugs and security issues, etc.).
He especially mentioned https://djangonaut.space , that's a great initiative to help people get involved with contributing. Same with https://djangogirls.org/ .
As a maintainer, you might also have to look for funding. There are options like "github sponsors". But also NLnet (from the Netherlands) and the German sovereign tech agency that sponsor lots of projects.
A best practice of good maintainers is to have good tooling. Automatic tests + coverage. Build documentation. Formatting checks. zest.releaser for good releases.
The most important part of being a maintainer: how do you treat people.
There's one big problem: AI. There are just too many pull requests and too many issues. You can never get through them if your project is reasonably project. Dealing with it is hard. Several projects made the choice to disallow AI contributions. Also read https://leidendeclaration.ai/ , for the same problems are entering math and science, too.
But on the other hand... in the icalendar project that he helps maintain, they got a new contributor that made his first contribution based on AI. He liked that: the person got enough confidence through AI. They now have an AI guideline in their contributor guide now.
There's are automated tools on github that can help you check pull requests and identify slop-generating accounts, for instance. A tip when confronted with suspected AI work: ask vague, clarifying questions. Just ask for a bit of clarification in a vague way: AIs can't respond to vague questions, but humans can.
"Once men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them." - Frank Herbert, Dune. Funny that he could write that 50 years ago.
Something mentioned in the discussion: people are now bidding on real github accounts in order to let AI bots use accounts that appear real...
Watch out with AI. One of the links he shared: https://pivot-to-ai.com/2026/09/08/students-who-dont-use-ai-are-ahead-on-every-measure/ . And, look at the kids: it was bad enough with social media, but AI is much worse. And freelancers are getting buried with soulless AI slop cleanup: artists get to clean up AI-generated images, for instance.
Choose wisely. A quote he wanted to give us to think about: teach the world you want.
Monitoring my washing machine - Michiel Beijen
Michiel has a 2021 Samsung washing machine that plays Die Forelle by Schubert when it is finished washing... But the washing machine sits in the garage so he can't hear the sound. It is a smart machine, so there's an iphone app for that! "SmartThings". But the list of data it wants to collect about you is horrendeous. And the app is almost 1GB! No...
There's also "home assistant", written in python. There's even a SmartThings API connection. But... from October 2026 onwards you need a $5/month samsung subscription!?!
There's also "Matter". They call it vendor neutral, standards compliant. Samsung supports it. But only for connecting Matter devices to SmartThings, not the other way around.
Next try: put a small camera in front of the washing machine's display, add a bit of OCR text recognition to detect the remaining time from the image and add an http interface to it. An old webcam couldn't provide a good camera. A raspberry Pi Camera 3 did the trick. (He later thought it would perhaps have been better to pick some old smartphone.)
He showed some graphs detailing how the washing machine estimates the time it will finish, including the adjustments it made halfway (adjusting for load or so).
Another approach that a colleague of him took: use a monitoring plug that measures the electricity used. Once the electricity usage drops off, the wash is finished.

Django: serve the change password well-known URL
When a password manager detects that a user's password has been leaked or reused, it can prompt them to change it, but the password change URL varies by site. The web's answer to such discovery problems is the reserved /.well-known/ URL namespace (RFC 8615), home to machine-readable files and endpoints like security.txt. A Well-Known URL for Changing Passwords is the web specification that uses this namespace to fix password page discovery. It reserves the URL path /.well-known/change-password to redirect to your actual change password page, wherever that lives.
Password managers that use this URL include Apple's iCloud Keychain (in Safari since 2019), Google Password Manager (since Chrome 86, 2020), and 1Password. web.dev has an excellent article explaining the specification and showing the Google Password Manager feature in action.
In this post, we'll look at implementing the change password URL in a Django project.
Add the redirect
The specification asks that /.well-known/change-password redirect to your change password page with a temporary redirect status code, for which you can use Django's RedirectView. The pattern_name argument looks up the target URL by name, so the redirect stays correct even if you move the page.
So, to add a redirect, plop this path in your root URLconf:
from django.urls import path
from django.views.generic import RedirectView
urlpatterns = [
# ...
path(
".well-known/change-password",
RedirectView.as_view(pattern_name="password_change"),
),
# ...
]
Note the path has no trailing slash, per the specification and counter to Django's default pattern. There's also no need for a name= argument, since nothing on your site should link to the URL.
password_change is the URL name provided by django.contrib.auth.urls, which serves Django's built-in PasswordChangeView. This assumes your URLconf includes those URLs, conventionally mounted at accounts/:
path("accounts/", include("django.contrib.auth.urls")),
If you serve your change password page some other way, swap in the appropriate URL name for pattern_name, such as account_change_password if you use django-allauth. Django doesn't check pattern_name until a request arrives, so a wrong name here fails only when the URL is visited, hence the test below.
Check with runserver and visit http://localhost:8000/.well-known/change-password - you should land on your change password page (or the login page redirecting you there with ?next).
Password managers only ever visit the URL on your live site (with HTTPS), so after deploying, repeat the check on your production domain.
For an end-to-end check, Chrome's password checkup tool (under Settings β Passwords) shows a "Change password" button for compromised entries, which should open your page directly once the redirect is deployed. To make the button appear without waiting for a real breach, temporarily change your saved password for the site to a deliberately weak one, like password123, which Chrome flags in the check.
Public users only
By the way, this feature is for public users and their password change pages, not admins. So don't use this feature to redirect to your Django admin's password change view, or any other private page. That would advertise those URLs to the world, undoing the common hardening of hosting Django's admin at a non-default path.
Check the resource that should not exist
There's a second URL to be aware of, a check for whether your server is broken. Some misconfigured servers respond with 200 to every request, serving an error page instead of using a proper 404 status code. On such a server, a client fetching /.well-known/change-password can't tell whether it found a real change password page or an error page.
The specification solves this with a second reserved path, gloriously named:
/.well-known/resource-that-should-not-exist-whose-status-code-should-not-be-200
Clients may request this URL to detect broken servers. If it responds with a 200, the server's status codes are deemed meaningless, so the client ignores the change password URL and falls back to something cruder, like opening your homepage.
Django responds with a 404 for unmatched URLs, so your site should pass this check, with nothing to implement. But a catch-all URL pattern could break it, such as one serving pages from a CMS, or a single-page application fallback that serves index.html with a 200 for any path. So it's worth covering with a test, included below.
Add tests
As ever, it's best to include tests to guard against accidental breakage, such as removal of the URL. Here's a test case covering both URLs:
from http import HTTPStatus
from django.test import SimpleTestCase
from django.urls import resolve
class ChangePasswordWellKnownTests(SimpleTestCase):
"""
Test the well-known URLs for changing passwords, per:
https://adamj.eu/tech/2026/09/16/django-change-password-url/
"""
def test_change_password(self):
response = self.client.get("/.well-known/change-password")
self.assertRedirects(
response,
"/accounts/password_change/",
fetch_redirect_response=False,
)
resolve(response["Location"]) # Check it's a real URL
def test_resource_that_should_not_exist(self):
response = self.client.get(
"/.well-known/resource-that-should-not-exist-whose-status-code-should-not-be-200"
)
self.assertEqual(response.status_code, HTTPStatus.NOT_FOUND)
Notes:
- Neither view uses the database, so the test case uses
SimpleTestCase, which blocks database access and runs a little faster. assertRedirectschecks both the status code, 302 by default, and the target URL.- The target URL is hardcoded, matching where the auth URLs were mounted earlier. If yours live elsewhere, adjust it. Hardcoding, rather than using
reverse(), makes the test check what clients see, rather than using any internal details of your system. - Passing
fetch_redirect_response=Falsestops the test client from following the redirect. Without it,assertRedirectswould fetch the change password page and fail, because when logged out that page responds with a second redirect, to the login page. resolve()raisesResolver404if the target URL doesn't map to a view. Calling it makes up for the skipped fetch above, checking that the redirect points at a real page rather than a typo.
Check your form's autocomplete attributes
The web.dev article also recommends annotating your change password form fields with autocomplete attributes, so password managers can fill in the current password and suggest a generated replacement:
autocomplete="current-password"on the current password fieldautocomplete="new-password"on the new password field(s)
If you use Django's built-in PasswordChangeForm, it's done for you, as the widgets there have included these attributes since Django 3.0.
But if you've built a custom form, it's worth checking that its fields carry the right attributes. You can set them through the attrs argument of each field's widget, for example:
from django import forms
class ChangePasswordForm(forms.Form):
current_password = forms.CharField(
widget=forms.PasswordInput(attrs={"autocomplete": "current-password"}),
)
new_password = forms.CharField(
widget=forms.PasswordInput(attrs={"autocomplete": "new-password"}),
)
...
If you're customizing Django's flow, prefer subclassing PasswordChangeForm, which carries those attributes already.
Fin
So there we go, a nice little standard to make your user's security a little easier. Add one URL entry and password managers can shepherd your users away from compromised passwords.
May your data never leak and your users passwords always be strong,
-Adam

Glyph Lefkowitz: ... but what about video games?
I get asked this rhetorical question a lot, in various forms:
Sure, datacenters might use a lot of energy, but you don't have to use a hosted frontier model to do software development. What if I just run a local open-weights model to do some coding, with an open-source coding agent? Video games also use my GPU. Is local model development any worse than playing a video game?
So I want to write down my comprehensive answer to this: Yes, using an LLM to write some code is worse than playing a video game, for a few reasons.
Video Games Are Interactive, LLMs Are Batch Jobs
Video games use compute to respond to human input. You are using your GPU while you are looking at a screen, displaying an image. When you are done playing, you shut off the game, and your computer goes back to idle. It's much less energy. By contrast, agentic loops with evals (the only kind of "AI" that is meaningfully any good at coding) are running hot, for days. To use the most recent example of such a thing, a very rough first sketch of an implementation of a Windows graphics API backend to help port a paint program to other platforms, it took 3 weeks of Claude time, "day and night". Do you play a lot of video games for 500 hours to make it past the tutorial level, while also using other computers for other things, as well as the rest of your carbon footprint?
Video Games Need Development, LLMs Need Training
Video games use compute to respond to human input during development, too. Your game has to be made, but your LLM has to be trained. LLMs use a historically extreme amount of power, probably using more than the entire Internet, but it's kind of hard to say. Still, it seems a reasonable estimate to within several orders of magnitude that even over a multi-year project with hundreds of developers, the power used to develop an individual video game is nowhere close to training even a small LLM.
This is true even for local models. OpenAI has openly claimed that DeepSeek "stole its intellectual property", and I have heard grumblings that none of the open-weights generalist models could realistically exist without the massive lift that the frontier labs are doing with their training, in various other ways too. Secrecy throughout the industry makes this kind of impossible to understand rigorously, but it seems fair to say that you are partially culpable for all that famously energy-intensive frontier lab training if you're using a local model.
And They Keep Needing Training
You also can't dismiss this as a sunk cost, because in order to stay current with industry developments, models need to be updated with new information from the rest of the world, which means that you need to keep training them. Beyond the energy for your own use, if you want a real-life agentic workflow that actually does useful stuff, practically speaking you would still need to update your local models over and over again, at least once every few months, which means you would be incentivizing continued energy consumption by whoever was doing that training for you, including the energy cost of scraping.
Let's Be Real Here, You Aren't Actually Using A Local Model
This question is a hypothetical thought experiment. Despite synthetic benchmarks that keep showing there isn't much difference between open weight and frontier models, nobody's actually using local models for much of anything beyond sharing those talking points. Depending on which benchmark you're looking at, maybe it's good enough or maybe it's worse.
As an inveterate AI hater, all these systems seem pretty bad to me, but it seems that people who find them useful tend to subjectively believe the frontier models are worth the premium, and that's what they're actually using. Once you have accepted that it is OK to use LLMs for coding at all, it seems like a very quick slippery slope on down to "we'll go ahead and use the frontier models for now anyway, but we could be ethically better in the future by switching to an open weights one, that option is always available".
There's A Reason We Have Data Centers
Devolving power usage to local LLMs might be good to make users responsible for their costs and decrease the impacts to communities that are physically next to huge concentrations of power utilization, not to mention generation. However, there's a reason that it makes sense for the providers to build these giant facilities: economies of scale reduce total power consumption, they don't increase it. If you do all the same stuff with a local model that they have to do in hosted environments, it will probably take more power, even though you will be incentivized to do different stuff. This incentive to "do different stuff" is why although local models can hypothetically hold their own against the frontier labs for some tasks, when people or businesses take their inference costs in-house they often find that it's too painful and move back to hosted LLMs.
There Are Problems Other Than Power
These are subjects for a different post, but you have to consider a lot of other externalities: AI psychosis, de-skilling, comprehension debt, cultivating a dependency, introducing security defects, limiting your design space based on what LLMs can understand, context rot, wasting time on invalid solutions, introducing unpredictability into your workflows. You still have to consider the total cost benefit ratio.
To Sum Up
Local LLMs might alleviate some of the harms from using the hosted frontier providers. There are fewer privacy concerns, you can measure your power utilization and be more directly responsible for it, you can build interfaces with affordances that are less oriented towards addiction and dependency than the major frontier labs' harnesses.
But they're not automatically "the same as playing a video game" just because they can use the same GPU.

Hynek Schlawack: Production-ready Python Docker Containers with uv
Starting with 0.3.0, Astral's uv brought many great features, including support for cross-platform lock files uv.lock. Together with subsequent fixes, it has become Python's finest workflow tool for my (non-scientific) use cases. Here's how I build production-ready containers, as fast as possible.

Glyph Lefkowitz: Adversarial Communication
As I have discussed in previous posts, "AIs" can make mistakes. In fact, they do make mistakes, and their mistake-making patterns are such that where and how they will make mistakes is both uncertain and constantly changing.
Thus, in any scenario where you want to attempt to make "productive" use of "AI", you must have a system in place for checking every result. Not checking some results; checking every result. If each result might have a consequence for you (and if it didn't have a consequence, why bother automating it?) and you cannot predict in advance which kinds of results will need verification, then verification is always required.
The verification often ends up being just as expensive as doing the work in the first place, which means that if you want your usage of "AI" to be personally profitable, you have to find someone else to externalize the cost of verification onto. This person becomes your adversary, and, if you are successful, your "AI's" victim.
The Ladder-Climber And Their Reverse-Centaur Rungs
One way that this constellation of facts can straightforwardly assemble themselves into a dystopian nightmare is the phenomenon, described by Cory Doctorow, of the reverse centaur. This is when your employer non-consensually turns you into the verification system. The "AI" does the fun part of initially performing the work, and then you do the boring part where you check if the robot is right and clean up its messes, even if everyone already knows that it would, in aggregate, be cheaper for you to do the work in the first place.
Reverse centaurs can be made from any automation, not only "AI" automation. I think that there is a reason that this term happens to have emerged in the "age of AI", though, and not with earlier automation technologies (even those which were considerably more viscerally horrific). That reason is: the wrongness of "AI" output is not merely a technical feature that must be compensated for, it is a generalized externality.
As I mentioned above, if you are responsible for the entirety of the work, both extruding the "AI" output and checking it, it's usually cheaper to have humans do the entirety of the work to begin with. When humans do the writing directly, we can check as we go, and thus verification doesn't need to be as comprehensive.
When "AI" coding advocates say "code review is the bottleneck", what they are observing is that the LLM is still rolling the dice for each PR, and a human is still necessary to verify that each of those rolls is a winner. But calling this process "code review" is a bit of a misnomer; it's not really "code review" in the traditional sense, it's human understanding.
Before the advent of "AI", the human understanding was implicit in the process of writing the code in the first place1, and the code review was a way of diffusing and extending that understanding. Now that the code can be authored with no initial understanding taking place, that cost has not gone away, it has moved.
Human understanding was always the bottleneck.
However, this is taking a collaborative view of a software project, where satisfying the needs and solving the problems of your customers are the goals. We can see that "AI" is a bad tool to satisfy those goals, because all it's doing is converting the first half of the work, that of understanding the code as you write it, to understanding the agent's output as you read it.
What if, instead, we were to take the view that every software company is a Hobbesian nightmare, red in tooth and claw? In this view, the only goal of a software project is for the individual developers to make their promo cycles and get their bonuses. Given that there is only a certain amount of money to go around, this is a zero-sum game where each programmer wants to look more productive than their colleagues.
Pretty much every organization finds it easy to reward "productivity" as expressed by lines of code emitted, but the benefits of doing thorough and thoughtful design, analysis, and code review very difficult to reward. In this world, an LLM is an invaluable tool for the sociopathic ladder-climber, particularly if your legacy organization is still structuring their workflows as if the person prompting the bot is "writing" the code, and then they get to foist off the act of "reviewing" the code onto someone else.
Here, the prompter effectively externalizes the cost of the LLM's failures but internalizes any benefits. The prompter will vibe-code a big feature, so large that the assigned reviewer can't possibly comprehend it all effectively. When this happens, the reviewer will, eventually, be pressured to approve it, even if they can try to spot a few problems along the way. The reviewer has their own work to get back to, after all, the obligation to review the prompter's (read: the bot's) code is a drain on their time that they are not going to get rewarded for.
If this feature is a big success, the prompter gets a promotion. If it causes a big issue, well, the reviewer must not have been careful enough.
This is why LLMs are "good for coding", and also why their biggest promoters keep having outages.
The Generative Gish Galloper
Coding is the biggest "success story" of this type of adversarial communication, but it is by far not the only instance of such a thing. LLMs create a new form of leverage that can turn Brandolini's law from a linear advantage into an exponential one. If you are engaged in a political debate where you want to overwhelm the other side in nonsense, an LLM can generate bullshit faster than it is physically possible for a human being to type, let alone respond thoughtfully. There is an asymmetry to the utility of this weapon as well: only one side of the political spectrum wants to flood the zone and destroy trust in institutions and the concept of truth. There's a good reason that the fascists love it.
Straightforward Spam and Fraud
This is kind of obvious, but LLMs can generate lightly-customized, plausible-looking text much more quickly than any human being. This facilitates their use in fraud, spam, and scams. In a spamming or fraudulent interaction, once again, the costs are externalized onto the victim: the recipient of a spam message has to do all the work of "checking" the LLM's output. Spammers already expect very low hit rates from boilerplate, and if the LLM can increase those percentages from 1% to 5% the technology will pay for itself; they don't need anything like reliable accuracy.
Customer "Support"
If you have any kind of commercial relationship with a company, I probably don't even need to mention this: customer "support" bots are a misery. Everybody knows it at this point. But customer support is usually conceptualized by businesses as an adversarial interaction, because it is a cost center. They maintain internal metrics on time-to-resolution and try to optimize them. Implicitly, this creates a dynamic where the goal of the customer service agent's job is not to solve your problem, but to emit noise that will cause you to think your problem is resolved, or to give up, as fast as possible. Unsurprisingly, LLMs can emit this noise faster than humans can, getting those customers off the phone. But those customers will remember those interactions, and the story outside the TTR metrics is horrible.
Similarly to the situation in software development, LLMs can look very good on paper for customer support, but mostly what they are doing is illuminating the problems with the industry's existing metrics, by turning "winning the metrics battle against the customer" into a more obvious and immediate defeat for the company's long term reputation.
"Education"
In 2026 it is sadly a fact of life that students cheat all the time using "AI", and that this cheating is very successful, in that the teachers find it very hard to detect.
LLMs are great for cheating on schoolwork because the student is externalizing the work of the checking onto the teachers, who are often starting at a disadvantage to begin with, at least in the US.
My view is that this is happening because of a divergence in the way that students vs. teachers (or, more accurately, "the broader educational system") view grading.
When a student is asked to write an essay, the teachers see the effort as both intrinsically worthwhile for the student, as well as useful as a pedagogical tool to evaluate and react to the student's progress. The student, by contrast, sees a stumbling block designed to knock them off the path to success and into a permanent underclass. It is no wonder that the student sees "AI" as useful to their own goals and has no compunction about deploying it.
There is a bitter irony that the ability to understand the inherent value of actually writing the essay on their own is the sort of thing that students can really only learn by writing a bunch of essays. There's no way that I can think of which makes the benefit legible as long as a shortcut is available.
The net effect here is a downward spiral, where the already-wobbling educational system is sustaining an attack that it doesn't have the resources to recover from. The individual students' attacks against their teachers and their schools' grading systems might appear to momentarily succeed, but they will win the battle and lose the war.
Spamming "For Good"?
Usually when we talk about someone unilaterally choosing to enter into an adversarial relationship, that's an "attack" and for good reasons we have a negative impression of the attacker. However, I would be remiss if I did not point out that there are some cases where the relationship was already adversarial; just because you're the attacker doesn't mean that you are evil.
For example we might imagine use-cases like automatically filing appeals for prior authorizations against health insurance. It's relatively well-known at this point that the main way for-profit insurers maintain their margins is by denying claims right up to the line of the policies themselves being fraud, so using a spamming tool to fight them might be entirely justifiable2 in that case.
Similarly, using an LLM could be justified in a fight against a company refusing to honor a warranty. One could imagine using an LLM to immediately generate replies and escalations.
However, even in imagined cases like these, the underlying problem is that the insurers and the vendors already have a tremendous amount of structural power, so it is more likely that they will have the advantage in deploying a communications weapon like an LLM, as well as enacting policies to simply ignore any LLM-based communication that you might submit. Worse, if these strategies were to become widespread, they might provide an excuse to reject any communications by feeding them into an unreliable "LLM detector" and issuing an automated "computer says no" even to hand-written correspondence.
It is also worth stressing that these cases are imagined, as compared to the very real coworker-abuse, spam, scam, fraud, and disinformation campaigns being waged in real life today.
Therefore, while legitimate uses might exist, it's hard to imagine that there's anywhere they would be genuinely valuable and sustainable. In the best case "AI" will provide a temporary advantage for underdogs that will provoke an arms race which the resource-advantaged adversaries will win in the long run, in the worst case the arms race itself will cement permanent structural change that will make things worse.
"Search" By Stealing
Most of the adversarial utility of "AI" is on the "write" side, since write-amplification is more obviously aggressive than reading. But the "read" side of LLMs - summarization and question-answering - can be a form of attack as well.
To begin with, the act of reading itself is currently enormously destructive, but that's arguably not a fundamental aspect of this technology. They could set reasonable rate-limits and respect things like robots.txt, as search engines have for decades now. They could also refrain from committing criminal levels of copyright infringement. But, today, using "AI" tools does suborn this sort of out-of-control crawling.
More insidiously, consider the scenario described in this YouTube video. The LTT Bros decided to try Linux again, and in the course of so doing, they had problems. When trying to solve these problems, they were faced with a choice: they could consult Reddit, or they could ask an LLM. Asking an LLM would "gaslight the heck out of" them, but they still found it preferable, because they would at least get an answer without getting yelled at.
Initially this sounds great. But it also means that you want to extract knowledge from a community, while mechanically eliding any values or norms that the community may want to impart as part of offering that knowledge. As someone who spent many years in a community tech support role, this is worrying. Many requests for support are people asking how to do things that will momentarily solve a superficial problem but create a long-term reliability problem or even an immediate security risk, that the question-asker doesn't want to hear about. Consider the question "I'm tired of entering my password so much, how do I make it so my laptop unlocks automatically". An obsequious chatbot will helpfully tell you how to do this without pushback.
But, this is also a sort of ethically murky area. The Linux community is somewhat famously, for many years now, a toxic cesspool of general hostility, misogyny, etc. It is certainly a good thing that people can get access to this knowledge without subjecting themselves to abuse. But it also means that the people with the power and the privilege to change the community for the better can just quietly withdraw, rather than fixing the problems. It also means that the positive elements of culture cannot be transmitted, and people will have no opportunity to learn about unknown unknowns.
In this case, the "adversarial" communication is with society. The thing that using an LLM for search lets you do is withdraw from society and avoid forming any personal connections. There are some personal connections which are painful and annoying, and so that can feel like a momentary balm. But the need to make connections in general is, like, the concept of society itself.
Who Am I Hurting?
LLMs are good at adversarial communication. They are so good at it, relative to their other benefits, that they will tend to make communications adversarial if you are not remaining vigilant about the possibility that it might do so. My request to you, dear reader, if you are going to use such tools, is to always ask yourself, "who might I be hurting, if I use an LLM for this?"
If you're using an "AI", who is its adversary? If you haven't given it one yet, who might the "AI" turn into an adversary? Who might you overwhelm with an asymmetric amount of output, or, if you're receiving information and not sending it, who are you taking that information from without consulting?
Figure out the answers to these questions and conduct yourself accordingly; the answer might be "yourself".

One of the reasons that software developers tend to prefer greenfield development is that when you are given a blank page, you can project your own specific understanding onto it. You can structure the codebase in a way that works for your brain, down to the variable naming conventions and the module layouts. LLM-assisted development makes everything into instant brownfield work, which makes developers instantly miserable; even those who are excited about the technology will frequently complain about how it feels like their agency has been stolen and their joy in the work has been diminished. But I digress. β©

Modulo the massive amount of other externalities involved in using LLMs, of course, but I don't have the time or energy to get into those here. β©
