I'm working on Small Transfers ( https://smalltransfers.com/ ), a payment platform that makes it very convenient for SaaS / API makers to provide a pay-as-you-go model to their customers. You can charge as little as 0.000001 USD per request. The platform uses our own system for tracking usage, which is settled through Stripe. No crypto, tokens, or wallets. If combined with subscriptions, the pricing can work similarl…

Do I understand correctly that in order to pay someone through your service I need to first create an account and then link it to a conventional card? If so, it's ultimately a PayPal remake?

Customers do create an account and provide a payment method, but they don't pre-fund or hold a balance, and they don't initiate a payment. Small Transfers is an API that allows merchants to charge very small amounts programmatically. At the end of each month (or earlier, if a threshold is reached), we charge the customer what they owe. This makes the tiny charges viable and avoids death-by-$0.30.

It's not a PayPal remake, since there are no wallets, no P2P transactions, and no stored funds. In addition, Small Transfers allows very small charges (as mentioned above), and provides customer OAuth and spending caps.

I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy. https://github.com/scallyw4g/bonsai I also wrote a metaprogramming…

"Function" link in the Examples section of the poof repo is 404.

I'm working on a new unconventional form of computing called "temporal computing" - as both a PhD and as a fledgling business. The idea is to use delays in time (It's called interval modulation) as the data. I have a video explainer on YouTube https://youtu.be/rXbzJxThgig?si=FYMleAgZ0GMNEqk9. It's a long road building your own computational model and I'm currently looking at Turing completeness, and models of multiplication.

"Google maps but for old maps": https://pastmaps.com This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS . It gets ~80K MAUs and just slowly and consistently is growing o…

This is brilliant. Nice work

Working on a dutch voting compass that uses real world motion votings as a way to determine which party fits you best. The Netherlands got an open API for this since last year, so it felt appropriate to start using it. see https://github.com/van-sprundel/partijgedrag

Top man! Thanks, I went trough the votings to see if the party I was thinking of matched actual voting behaviour in the 2e Kamer. It kinda did, but I was suprised another party matched a bit more.

Since that second party also comes forward in other voting compasses I might be more inclined now to vote them instead.

I’ve been working on an app called Lång. A daily spending guide. It shows you what’s okay to spend based on how much needs to last how long. For over a decade, I’ve thought about how most people seem to resist the advice about money. And also how all advice is based on the same idea: seeing where your money went and making monthly plans based on that. I think people feel that this is a poor match for how money works.…

I've been wanting to build something like this for myself, but partnering/integrating with banks seems to be the main difficulty. How do you solve this? And which cards / banks does it support? Also, what does the name mean? It might be a tad difficult to google, unfortunately, since I imagine that googling "lang" would come up with a lot of other results.

It doesn’t integrate with banks. You log as you spend. It’s a common question, but I think there are many reasons to keep it manual. It keeps you aware of what you have left. And automation won’t ever be perfect, so you must keep an eye on it and adjust things.

The app focuses just on your everyday spending. You don’t log bills and subscriptions. And it’s not about being exact. You can add the rough total of what you spent. It acknowledges that when you plan your spending, it’s really just a guess. And you’ll adjust the plan as you go.

What did you have in mind when you thought about building something like this?

The name means ’long’, and is pronounced similarly. Naming is of course hard. I’m hoping that it will be something you remember.

Working on an AI/Governance and compliance system that also integrates with the cli for teams developing the actual code and the systems that are commonly used, GitHub, bitbucket, open policy agent, collibra etc..

Used by enterprises for compliance, reporting and answering questions like, who owns this ai model, whats the monitoring plans, where is it running, what approvals does it have, what policies are applicable (geographic etc).

Earlier quoted context omitted.

Do the same for chicken eggs

Are you making a joke, or is there some use for that? (I would think of all species on earth, chickens are the easiest to get eggs for once you exclude the insects, but lack of domain knowledge means I could easily be missing something)

Not the person you asked, but there is a lot of research in this for meat so it would be interesting for eggs as well, as replacing them when you are vegan is not that easy.

Since last year i've been working on something that surprisingly didn't exist before, an app where you can rate sports games.

https://rategame.io/ and on the app stores(I really recommend the app if you want to check it out, especially on a phone)

We've expanded on the concept with rating stadiums, creating lists, voting for player of the game and more as we are trying to become the letterboxd for sports.

I'm building a way to automatically keep code base documentation updated. https://github.com/apps/askmanu

Right now we're focusing on reference docs and soon the app will be able to write full documentation content.

We want to focus on incremental changes to docs (one PR at a time) so the content is easy to verify and merge.
