Only in the conceptual stage right now. So far my thoughts are.

An app framework targeting modern C++ (>C++20) based on Boost.Fiber and stdexec( sender/receivers when C++26 releases)

I got inspired by a recent Java talk[1] from a Netflix employee about how they are building. I have the pretty strong opinion that async/await are implementation details and shouldn’t be exposed in APIs. They effectively have the compiler/runtime generate a state machine for you and you wouldn’t put a state machine in an api. Using C++ though we do have low level access to the CPU and there is no reason we cannot just use stackfull coroutines. This allows you to write literally synchronous code but it will defer blocking operations to an even loop and allow concurrency.

For GUI at least in the beginning Im thinking that I just spawn a native window and it’s up to you how you draw to that. I’m targeting something basic on linux myself which means it will probably just be direct calls to the wayland compositor to create a window. Getting a context etc will be up to the user since my idea would be in windows we use C# and on macos we use swift for UI. Documenting and building tooling around getting those languages integrated feels like it would provide more benefits than actually trying to reinvent the wheel in C++.

Likewise HTTP client will just wrap libcurl, for server side Im actually thinking of just calling into golang. HTTP servers aren’t the hard part, it’s all the infrastructure around it that is the hard part and well golang handles that better…

An open-source, self-hostable app for sending out newsletter to your friends and families. I'm mostly making it for myself because I want to share what I've been up to and family photos, without uploading it to Facebook or whatnot. At the moment, the flow goes like this: 1. During the week, write posts for things that have happened. 2. Posts can be assigned to groups. (family, friends etc). 3. At the end of the week…

Nice project, I'd totally set this up for myself as social media replacement. Please let me know once your MVP is ready. My main concern would be to overwhelm recipients if they'd ever get included in multiple people's newsletters.

I've been building on the opposite end of this. It's an open-source form submissions forwarder. I built it mostly because I wanted a service thats transparent, with usage based pricing that I could use economically for my low traffick sites.

Sometime this year I want to add docker-compose to make it easier to self host. Currently it's all manual. https://simplecontactform.org

I’m in the midst of reviving https://beatscratch.io (https://github.com/falrm/BeatScratch-Flutter). I’ve let it sit unmaintained (because it’s been “good enough” at its job) for a couple of years, through the addition of null safety to Dart and numerous Flutter changes (though I have to say, its API stability over this time is pretty impressive!). I’ve also GPLed the code in that time and the new version will also be under that license.

Once I’ve got at least the iOS and web release pipelines working again, I plan to replace its Reddit integration/sharing features with an implementation based on https://jonline.io (https://github.com/JonLatane/jonline), the AGPL, Rust/gRPC-based social network I’ve built in the intervening time.

I’m also planning on adding more detailed (left to right audio) panning and other output controls, oriented towards using BeatScratch live with other musicians. My hope for this is to use it to complement my own musical practice I’ve been working on, outside of all this 1s-and-0s programming time.

For the past several years, I've been tinkering on and off with something that might be called a "game engine", except there's not enough of it. More of a "conceptual framework", or maybe "organizing principle". Basically, I cut the idea of the Entity-Component-System down to the bare minimum and provide some structure and queries.

Here's a presentation, includes examples: https://hg.sr.ht/~oofoe/candheat/raw/dox/intro.pdf?rev=tip

It's fairly free form, so you can do almost anything you want, but still structured and "legible" for computers and the person debugging it. I wrote it in a Lisp that compiles to JavaScript, but there's no reason you couldn't implement it in any language that supports associative arrays -- idea is that the language has most of what we want, just need to organize it a little. I think the idea is useful enough, that it's potentially useful for more than "just" games.

Repo with several more-or-less worked examples: https://hg.sr.ht/~oofoe/candheat

Recently used it for a Lisp Game Jam entry, which someone described as "Helltaker meets the Magic School Bus": https://oofoe.itch.io/class6

About 800 SLOC, compiles down to just under a hundred lines of JavaScript. This includes the utilities, the "engine" (keyboard handling, overlays, text and art composition, animation, sound effects, etc.) and the game logic itself (which includes a level editor).

Thought it was goofy that I was still reading newsletters through my inbox. I really don't want to open my email unless I'm working. Anyways, some friends and I made Scrollz to fix that and also add some cool features to the newsletter reading experience. AI summaries, newsletter discovery, audio narrations, etc. https://www.scrollz.co/

I'm also not a fan of email newsletters, and the reading interface of scrollz looks nice, but I'm not understanding how scrollz actually fit into the reading workflow. How do the newsletters in my inbox get opened for reading in scrollz?

An employee advocacy platform that helps companies amplify their brand reach and thought leadership through their employees’ social networks. It integrates with tools like Slack and Microsoft Teams, allowing marketing teams to easily share curated content that employees can like, comment on, or reshare without needing to leave their workspace or log into LinkedIn.

A deep research system to discover if your dumb saas idea is already out there.

I got sick of starting a project only to later discover significant competitors or features of the marketplace I missed, despite looking. I can now do in minutes what used to take me days.

I’m working on https://postcardlove.com — a super simple site that lets you send real postcards using a photo from your phone. No login, just upload, write, and send. It started because I wanted to send my sister an old photo for her birthday, and instead of using CVS or Shutterfly like a normal person, I ended up building it using Bubble and Lob. Now I’m exploring the B2B angle — a friend asked if I could do postcar…

yay, postcard apps! this is my space, too. there's something really fun about making an API call and then postcards shoot out the other side.

i like your site and the visual design, very simple and straightforward. at $3.99 it does seem rather expensive compared to other options out there (i have an idea on how much it costs you). also, having some actual pictures of what the cards look like on the website will surely help with conversion.

the first postcard app I built is Three Kind Words (https://threekindwords.com). it’s a small vending machine on the internet where people anonymously send a friend three postcards, one word at a time. the first two cards are unsigned, and the last one reveals who sent them. it’s meant to be a slow, kind surprise in the mail. we've sent over 250 cards so far.

my latest postcard app is Slow-Mo Rainbow (https://slowmorainbow.com). this one lets you send a rainbow in the mail, one postcard at a time. i just launched it last week and am still getting the rough edges worked out, but in the spirit of the thread, i'm sharing it here.
