#412I am productionizing a golang project which I have working ... it parses an input image at the pixel level to synthesize its audio equivalent ... inspired by a 3Blue1Brown video on Hilbert Curves ... as it traverses the entire image pixel by pixel it assigns to each pixel an audio frequency which it increments for next pixel ... in doing so it collapses the 2D image into a 1D line of pixels ... then it engages audio oscillators at each element of this line at the assigned frequency with volume determined by the light intensity of the respective source pixel ... it then aggregates all these audio tones into a single tone which represents the source input image ( inverse Fourier Transform ) ... entire process above is reversible so the system can go from image to audio as well as audio to image ... goal is to allow Blind people to see with their ears ... alternatively it can allow the Deaf to hear with their eyes ...

This is brilliant
Is it? It just seems wasteful and unnecessery. Even gifts cards are pretty stupid for anyone that has access to a credit card. It’s strictly worse than having the actual cash for all but the unbanked (including kids).
Agreed... my first thought was "wow, this would create a lot of unnecessary waste going into a landfill."

#414I'm working on a bike part compatibility database for cyclists and anyone else who may work on bicycles. https://builder.bike
I love this, how are you sourcing compatibility data?
Thanks! I'm using this as an experience to teach myself mainly. I'm not an expert cyclist but I prefer to DIY when I can.
For example, I looked at tires and wheels as a good litmus test. What were the minimum pieces of information that you need to know to pick the right tire or wheel and make those the only filters on the site.
In terms of expertise, I've mainly farmed out to the cyclist community on Mastodon and served requests on a first-come-first-serve basis. For example, one person pointed me to sheldonbrown.com for their article on tires and it was really illuminating.

Wait, hang on, not wanting to be served poison for dinner is a cold calculating reptilian thing to do? What else do these reptilians do? Run the government?
What these reptilians do is only think about themselves. If you're invited for dinner it doesn't mean that somebody owes you a meal. It means somebody wanted to make a nice gesture towards you and get to know you more intimately, perhaps to discuss important things. You eat something before you go, because it's not about the food. You can ask about the ingredients when you are at the table.
So people with allergies shouldn't tell the people who will be preparing food for them about their allergies before the food is served?

Just playing with it now for German, and the second ever set of words it taught me were ‘Er’, ‘aus’, and ‘Dorf’, and it then asked me to fill in the blank: Er ist aus unserem Dorf …only it hadn’t taught me ‘unserem’, so I had no way of even guessing the right answer. (I just had to get it wrong intentionally.) Is this intended behaviour or should it also have taught me ‘unserem’ first?
Thank you for checking it out! That is not the intended behaviour, but happens sometimes when the NLP pipeline and the dictionary don’t agree on the part-of-speech of a particular word. I’ll have to run a script identifying all such cases in the built-in decks and most likely correct them by hand. Happy to hear any other thoughts or issues so I can make it better :)
(Obviously) I don't fully understand your architechure, but isn't there a (relatively) simple check that it shouldn't test for a word that it has never taught?
(And on the bright side, I'm sure I'll remember unserem now!)

#417it is not easy to find good software engineer job in taiwan. I also try to build a good community of english speaking engineers. If you live in taipei or interested moving, it’s on https://taipeidev.com
as someone who lived in taiwan before this is dope.

#418An open-source, type-safe http client to your postgresql database. It let's you access your database directly from your react components. It's fast, safe and performant. Think Graphql but you don't need to implement resolvers, it's all generated from your database schema. If this sounds interesting to you, ping me (email on my profile) :)
Sounds cool. How is it different from PostgREST?
What I would actually like to have is a generic PostgREST, sitting on top of sqlalchemy or something like that so that I can start on sqlite or DuckDB and then swap out the RDBMs if needed.

#419I've been building algorithmic trading models for the last 4+ years. After trading them successfully with my own capital for more than a year, I launched https://grizzlybulls.com as an alternative to the traditional hedge fund monetization path. Since launching in January 2022, we've significantly outperformed the market with lower volatility and reduced max drawdown: Model - Return - Max drawdown S&P 500 (benchmark)…
This is nice to hear about. Can you tell me more about how your live results matched or diverged from your backtesting?
Did you list the returns of the commodities as a comparison, or are you trading those futures as well in the mix? (I know you only talked about ES/MES)

#420Creating the best place to discover and distribute Christian apps and tools: http://faith.tools While some may not see this as a problem, it’s actually kind of hard to find great Christian apps in the sea of old blog posts of top 10 apps all taking about the same apps I’d consider myself an indie hacker and built many tools for Christians, but later discovered there’s no great place to distribute those apps. Hear me…
Great idea and thank you! Is there a way to filter by platform (i.e., Android)?
