1. Show HN: A web app for hosting quiz games
Author: damon_default
Description: I wrote a tiny version of this in Covid lockdowns because I felt playing trivia with friends was a bit boring, and we should all have buzzers like on game shows. I’ve been using it as a test project for trying out frameworks for years but I finally polished it up into a proper product. I’d love it if people try it out and give me some feedback, at the moment it sends you an emailed validation code which might put some people off trying it, if it does put you off then please let me know, I was also toying with just having free time-limited games.

9. Show HN: Aesthetic Computer
URL: https://github.com/whistlegraph/aesthetic-computer
Author: justanothersys
Description: Aesthetic Computer is a mobile-first runtime and social network for creative computing.
AC’s client interface is designed to function like a musical instrument, on which users discover their own memorizable paths in the network of commands and published pieces. As users grow their literacy through play and exploration, they are able to improvise, recombine, and expand their performable repertoire.
I started writing Aesthetic Computer in 2021 because I desired new tools to author, publish and connect the creative software toys I had been making in my art and education practice for 10+ years. The last of these before AC was https://nopaint.art, discussed on Hacker News in 2020.[0]
** Try Me **
Visit https://aesthetic.computer and press the top left of the screen or type any key to activate the prompt.
In the AC prompt, enter names of built-in toy and utility pieces like notepat[1], or boyfriend and those published by user handles like @bash/hub.
Return to the prompt by pressing the name at the top left corner, your browser’s back button or the [Esc], [], or [Backspace] keyboard shortcuts.<p>Enter listat the prompt for a scrollable index of pieces and commands.<p>Most of AC is open to anonymous users. Some pieces likechatormoodsrequire a registered @handle to fully participate and post data.<p>Every piece on AC is URL addressable. For example, users who enjoy usingnotepatcan skip the prompt entirely by bookmarking <a href="https://aesthetic.computer/notepat" rel="nofollow">https://aesthetic.computer/notepat</a>.<p>QR codes to share any piece can be generated by prefixing the piece withshareat prompt as inshare notepat`.
Here are a some recipes to try:
To dive in more you can read the technical history [2] or try coding your own AC piece[3].A. Make a Painting1. Enter `new 128` to start a new 128x128 pixel painting. 2. Enter `rect red` and drag to paint red (or any CSS color) rectangles. (Or try other primitive brushes like `line`, `shape`, and `fill`.) 3. Press the command name in the top left corner to return to `prompt`. (Or use the [Esc], [Backspace], or [`] on the keyboard.) 4. Enter `smear` and drag to use a pixel scattering brush, then return to `prompt`. 5. Enter `dl` to download a timestamped PNG, `done` to publish the painting on AC servers, or `print` to mail order a real sticker.B. Play a Melody
1. Enter `+` to open a second prompt window. 2. Enter `metronome 120` in the second prompt window to keep rhythm at 120 BPM. 3. Enter `notepat` in the first prompt window to play tones in regular time. (Or try `bleep:sine 4x4` for a randomized playable tone matrix.) - Bonus - 4. Record a `notepat` performance as a 7s looping, downloadable video by entering `tape notepat`. 5. Play `notepat` in person with others by generating a QR code via `share notepat`.C. Say “hi” in
chat.1. Enter `imnew` or press [I'm New] on a deactivated prompt to register. 2. Verify your email. 3. Set a @handle by entering `handle ur-handle-here`. 4. First-time handle setters are automatically routed to `chat`. 5. Say "hi" and request technical help from myself (@jeffrey) and others.

11. Show HN: EnvCloak: lightweight, env file encryption – ready for CICD pipelines
URL: https://github.com/Veinar/envcloak
Author: k4k4
Description: When someone here told me to focus on something more useful than reinventing the wheel. So. EnvCloak, a lightweight and simple tool for securely managing sensitive environment files. The design focuses on simplicity - just a few intuitive commands using the Click Python library. I assume seamless integration with CI/CD workflows.
The aim is to provide a streamlined solution without the need for clunky tools. If you’re tired of complex configurations or bloated alternatives, this might be worth a look!
I would appreciate any feedback, feature ideas or input on how to improve this solution. I’d love to hear your thoughts! Regards!

14. Show HN: Angus TV+ – Track What You Watch, Share, and Save on Streaming
Author: true_pk
Description: The thing I’ve been using to track what I’ve been watching is now open for a loose public beta, so you can give it a try and message me a half-hearted, “uh, it’s … good?”
If you don’t know what I’m talking about, here’s the blog post about it: https://angus.plus/r/0298ead0?m=a7cf7962-de24-4b53-8778-8fd8…
And here’s my page: https://angus.plus/r/0e78827e?m=a7cf7962-de24-4b53-8778-8fd8…
It’s called Angus TV+ … ‘cause … why not? Mostly I got tired of looking for names and domains. Leave that problem for another day.
How To Test It
- Go to https://tv.angus.plus
- Create an account, which’ll create your page.
- Add things you watch using the search field.
- Set your page to public or private. Share it if it’s public and you want to do that.
- Report bugs, feedback and what you’d like to see from a thing like this. (See the Problem / Vision section below.)
- Expect a lot of rapid changes.
This is just the first round of features open for testing. The 2nd round will involve finding other pages to follow, managing your subscription services, and building out the community features that really are the point of the whole thing.
The Problems
1. I keep forgetting about my favourite stuff. I watch movies and TV that I love, then before long it’s just a vague memory. We used to buy and collect our favs. Now they pass by like a in a hurricane.
2. Watching stuff isn’t very social. For something we all love, our ability to bond and talk about the stuff we watch is pretty strained. We’re all watching something completely different, at different times, and have different streaming services. By the time I’ve watched the latest Star Wars series, everyone else has already forgotten it.
3. Streaming services don’t make it easy. Unlike our music services, which amazingly have almost everything for one low price, movie and tv streaming is a mess. Stuff appears, disappears, and it gets pretty expensive to have all of the services all of the time. Then there’s the added complication of the internet constantly giving you US streaming service info.
The Vision
1. Fixing problem #1 is pretty easy with a piece of paper and pen. Or a spreadsheet. But why not have a nice, clean interface to manage it? That part is already built and I’ve been using it since the beginning of 2024. It’s just become a normal habit after I watch something to open the page and click in a rating. I look back at my page now and it is awesome to browse. Like a great shelf of physical media used to be. You can do this RIGHT NOW! FOR FREE! HIGH FIVE!
2. Fixing the second and third problems is so much harder. But I have the totally original idea to combine tracking with following. There’s a definite goodreads-for-tv-and-movies analogy here, but in this case it’s as much about WHERE you watch it as WHAT you watch. For example, imagine you follow 10 people. But you only have two services right now. (Say Netflix and Crave, for example.) You can get a feed of what those 10 people are watching on those two services, ranked by their rating. This is why it’s important for it to be Canada-only.
3. Now imagine if your whole group used the same two services every quarter, and then switched them, and formed a watch club, kinda like a book club. And now you’re saving a lot of money not having every service, AND you’re having better convos about TV shows with your friends ‘cause you’re all watching the same stuff AND you’re having group movie nights. Maybe the whole country is having group movie nights.
Alright, your turn. I need to get this out of my head and get some other opinions.
Try it if it sounds like something you wanna try and tell me what you think. Tell me what features you’d find useful, even if you don’t wanna sign up. Tell me why it’s pointless because x, y & z exists. Text me a bowl of rice emoji. Whatever feedback you got I’ll take.

15. Show HN: Binge-watch or download clips from twitch
URL: https://www.twiclipsaver.com/
Author: toutoulliou
Description: I wanted to train my devloppement skill so I made TwiClipSaver.com at a side project from my work.
This idea come to my mind after creating many youtube video about clips compilation from twitch, for that I needed downloader for the clip and tools to find best clips so I create my own tools and group them in the same place. In my site, you can found 4 sections:
- Download page for downloading the clip by their url
- Clips page to watch random clips from twitch
- Trending page to watch the most viewed clips by game/date
- Blog page to see news about twitch
Because I think it can be interesting for other I decide to create this website and share with you to have some feedback about the project and maybe someone have good idea to add more feature. I use Django, HTMX and Tailwindcss/FlowBite to make this website.
The next feature I would like to add it’s the possibility to create user for liking the clip you like the most and rewatch it.
If you have any questions I’ll be happy to answer.

22. Show HN: Django Boot
URL: https://github.com/grandimam/django-boot
Author: grandimam
Description: Hi HN,
I’ve built a Django Starter Template to simplify and enhance the process of starting a new Django project. It’s focused on improving developer experience (DX) with:
- Dynamic Initialization: Automatically replaces placeholders like {{ project_name }} during setup.
- Pre-configured Tools: Comes with Black, isort, Flake8, and pre-commit hooks out of the box.
- Modular Settings: Separate configurations for development, testing, and production.
- Makefile Commands: Quick access to tasks like formatting, linting, and running the server.
- Clean and Scalable Structure: Encourages best practices for projects of any size.
Why this template?
Unlike many Django boilerplates, this one uses Django’s native startproject —template command (no Cookiecutter needed!) and is designed to be flexible without being overly opinionated. It’s perfect for beginners, experienced devs, and teams looking for consistency and speed.
Comparison with Alternatives:
- No extra dependencies like Cookiecutter—just Django’s built-in tools.
- DX-focused with Makefile shortcuts and pre-commit hooks for a smoother workflow.
- Production-ready yet easy to customize.
Target Audience:
This is great for:
- Beginners needing best-practice scaffolding.
- Teams wanting consistent project setup.
- Intermediate/advanced devs who need a solid foundation they can tweak.
- Check it out on GitHub: https://github.com/grandimam/django-boot
I’d love to hear your thoughts and feedback. What features would you like to see in a Django starter template?
